技术领域Technical Field
本发明涉及岩土钻进设备，尤其涉及一种矿井开采岩石钻进设备。The invention relates to rock drilling equipment, in particular to rock drilling equipment for mining in a mine.
背景技术Background Art
在利用钻机进行岩石钻进的过程中，出于确保钻进准确性等方面的考虑，经常需要观察钻进部位的情况（例如钻头的钻进位置、钻杆相较于孔洞的位置和状态、碎屑排出状况等），而这通常是由人眼近距离直接观察作出的。而由于在钻进过程中容易发生碎屑飞溅的状况，这种依靠人眼近距离直接观察的方式容易对工人的面部和呼吸系统产生损伤，为此，工人需要穿戴厚重的防护设备（如面罩和围脖），从而给工人的体力和舒适性造成负担，或者使用摄像头进行观察。而现有的采用摄像头进行观察作业的观察设备使用起来不够方便：稳定性差；需要额外消耗能源；无法起到防护效果。突出了现有技术的不足之处。In the process of rock drilling with a drilling rig, in order to ensure the accuracy of drilling, it is often necessary to observe the situation of the drilling site (such as the drilling position of the drill bit, the position and state of the drill rod relative to the hole, the debris discharge status, etc.), which is usually observed directly by the human eye at close range. However, since debris is prone to splashing during the drilling process, this method of relying on close-range direct observation by the human eye can easily cause damage to the worker's face and respiratory system. For this reason, workers need to wear heavy protective equipment (such as masks and neck scarves), which puts a burden on the worker's physical strength and comfort, or use cameras for observation. However, the existing observation equipment that uses cameras for observation operations is not convenient to use: poor stability; requires additional energy consumption; and cannot provide protection. This highlights the shortcomings of the existing technology.

使用时，通过钻机1带动钻杆2和钻头3进行转动，实现对岩石的钻进，并形成孔洞，在钻进过程中，通过工具或手扶使得内支撑筒4前移，直至前支撑架6前端抵于钻进表面，通过机械角度调节机构12调节前防护板8和后防护板9的角度至合适位置，使得后反光镜11向前倾斜，使得前反光镜10向后倾斜，即可通过前反光镜10折射出孔洞周围的状况，然后人为观察前反光镜10即可。一方面，工人无需直接观察孔洞周围，降低了直接被飞溅碎屑伤害的风险，另一方面倾斜的前防护板8和后防护板9能够对飞溅的碎屑进行阻拦，从而提高安全防护性能，且机械结构稳定性好，不消耗额外的能源，使用起来比较方便。When in use, the drill rig 1 drives the drill rod 2 and the drill bit 3 to rotate, so as to drill into the rock and form a hole. During the drilling process, the inner support tube 4 is moved forward by tools or hand support until the front end of the front support frame 6 is against the drilling surface. The angles of the front guard plate 8 and the rear guard plate 9 are adjusted to a suitable position by the mechanical angle adjustment mechanism 12, so that the rear reflector 11 is tilted forward and the front reflector 10 is tilted backward. The front reflector 10 can reflect the conditions around the hole, and then the front reflector 10 can be manually observed. On the one hand, workers do not need to directly observe the area around the hole, which reduces the risk of being directly injured by flying debris. On the other hand, the tilted front guard plate 8 and the rear guard plate 9 can block the flying debris, thereby improving the safety protection performance. The mechanical structure has good stability, does not consume additional energy, and is relatively convenient to use.
各所述后防护板9前端分别内嵌固定有电灯13，所述电灯13与外界的电路控制系统相电性连接。An electric lamp 13 is respectively embedded and fixed at the front end of each rear protection plate 9, and the electric lamp 13 is electrically connected to an external circuit control system.
进一步的，跟随后防护板9同步移动的电灯13，能够对孔洞周围的状况进行聚光照射，从而在后反光镜11和前反光镜10上形成明亮的孔洞周围的影像，便于进行观察。Furthermore, the electric light 13 that moves synchronously with the rear guard plate 9 can focus light on the conditions around the hole, thereby forming a bright image around the hole on the rear reflector 11 and the front reflector 10 for easy observation.
所述外支撑筒5后部同轴螺纹连接有调节筒14，所述调节筒14前部同轴转动连接有圆环状的前传动架15，各所述后防护板9后端中部分别固定有一号铰接座16，所述前传动架15圆周等角度径向铰接有多个内支撑臂17，各所述内支撑臂17前部分别与各一号铰接座16相铰接，所述调节筒14后端部设有两个相互平行的夹持台18，所述调节筒14同轴转动连接有调节座19，所述调节座19后部呈相较于调节筒14同轴的六棱筒状，所述调节座19转动连接有相较于调节筒14同轴设置且呈圆盘状的后传动架20，所述后支撑架7圆周等角度径向铰接有多个外支撑臂21，各所述前防护板8远离前支撑架6的端部固定有二号铰接座22，各所述外支撑臂21前部与各二号铰接座22相铰接。The rear part of the outer support cylinder 5 is coaxially threadedly connected with an adjusting cylinder 14, and the front part of the adjusting cylinder 14 is coaxially rotatably connected with a circular front transmission frame 15. A No. 1 hinge seat 16 is fixed to the middle of the rear end of each rear guard plate 9, and the front transmission frame 15 is radially hinged with multiple inner support arms 17 at equal angles around the circumference. The front of each inner support arm 17 is hinged to each No. 1 hinge seat 16, and the rear end of the adjusting cylinder 14 is provided with two mutually parallel clamping platforms 18. 14 is coaxially rotatably connected with an adjustment seat 19, the rear portion of the adjustment seat 19 is in the shape of a hexagonal cylinder coaxial with the adjustment cylinder 14, the adjustment seat 19 is rotatably connected with a rear transmission frame 20 coaxially arranged with the adjustment cylinder 14 and in the shape of a disc, the rear support frame 7 is radially hinged with multiple outer support arms 21 at equal angles around the circumference, and a No. 2 articulated seat 22 is fixed to the end of each front guard plate 8 away from the front support frame 6, and the front portion of each outer support arm 21 is hinged to each No. 2 articulated seat 22.
通过工具（如扳手）对夹持台18进行夹持，使调节筒14进行转动，从而沿着外支撑筒5进行轴向移动，即可带动前传动架15和内支撑臂17进行移动，从而调节后防护板9和后反光镜11相较于外支撑筒5的径向角度，同理，通过工具对调节座19后部进行夹持，使其进行转动，从而沿着调节筒14进行轴向移动，即可带动后传动架20和外支撑臂21进行移动，从而调节前防护板8和前反光镜10相较于外支撑筒5的径向角度。The clamping platform 18 is clamped by a tool (such as a wrench) to rotate the adjusting tube 14, thereby moving axially along the outer support tube 5, and the front transmission frame 15 and the inner support arm 17 are driven to move, thereby adjusting the radial angle of the rear guard plate 9 and the rear reflector 11 compared to the outer support tube 5. Similarly, the rear part of the adjusting seat 19 is clamped by a tool to rotate it, thereby moving axially along the adjusting tube 14, and the rear transmission frame 20 and the outer support arm 21 are driven to move, thereby adjusting the radial angle of the front guard plate 8 and the front reflector 10 compared to the outer support tube 5.
所述后传动架20在前后方向上贯穿，所述后传动架20的前后贯穿处闭合固定有透明的观察板23。The rear transmission frame 20 penetrates in the front-to-back direction, and a transparent observation panel 23 is closed and fixed at the front-to-back penetration of the rear transmission frame 20 .
通过观察板23能够方便的观察孔洞周围和前反光镜10的状况，并对工人的面部进行防护。The observation plate 23 can be used to conveniently observe the conditions around the hole and the front reflector 10, and protect the worker's face.
所述前防护板8、外支撑臂21和后传动架20外共同套接有能够拆卸的过滤罩24，所述过滤罩24由弹性的透气透水面料织成，所述过滤罩24前后两部沿前后方向贯穿，所述过滤罩24前部的贯穿处延边缝制固定有前弹性带25，且后部的贯穿处延边缝制固定有后弹性带26，所述过滤罩24前部开有多个插口27，各所述二号铰接座22分别固定有向外的凸起28，各所述凸起28分别与各插口27相插接，所述前弹性带25左右两部各固定有卡扣29，所述卡扣29与前支撑架6左右两部相插接，两所述卡扣29在前弹性带25的弹性拉扯下具有相互远离的趋势，所述后弹性带26沿前后方向贯穿有多个定位孔30，所述后传动架20后端固定有多个沿前后方向的定位销31，所述定位销31后部呈尖端状，各所述定位销31与各定位孔30相插接。The front protective plate 8, the outer support arm 21 and the rear transmission frame 20 are collectively sleeved with a detachable filter cover 24, the filter cover 24 is woven from an elastic breathable and water-permeable fabric, the front and rear parts of the filter cover 24 are penetrated in the front-to-back direction, a front elastic band 25 is sewn and fixed along the edge of the penetration of the front part of the filter cover 24, and a rear elastic band 26 is sewn and fixed along the edge of the penetration of the rear part, a plurality of sockets 27 are opened at the front of the filter cover 24, and each of the second hinge seats 22 is respectively fixed with an outward protrusion 28, each of the protrusions The starter 28 is respectively plugged into each socket 27, and the left and right parts of the front elastic band 25 are each fixed with a buckle 29, and the buckle 29 is plugged into the left and right parts of the front support frame 6. The two buckles 29 have a tendency to move away from each other under the elastic pulling of the front elastic band 25. The rear elastic band 26 is penetrated by a plurality of positioning holes 30 along the front and rear directions, and the rear end of the rear transmission frame 20 is fixed with a plurality of positioning pins 31 along the front and rear directions. The rear part of the positioning pins 31 is pointed, and each positioning pin 31 is plugged into each positioning hole 30.
进一步的，在钻进过程中，由于前支撑架6前端抵于钻进表面，因此碎屑和排屑液（如果向孔洞内灌注的话）能够通过前支撑架6进入到过滤罩24内进行过滤，从而能够将粉尘和碎屑进行拦截收集，并将液体漏出，继而减少对外界的污染，同时能够避免碎屑进一步溅射而对人身造成伤害，当需要清理时，将定位孔30与定位销31脱离，然后将过滤罩24向前适当移动，即可将收集物排出，当进一步向前移动时，使得卡扣29与前支撑架6脱离插接即可将过滤罩24完全卸下。Furthermore, during the drilling process, since the front end of the front support frame 6 is against the drilling surface, the debris and chip removal liquid (if poured into the hole) can enter the filter cover 24 through the front support frame 6 for filtration, so that the dust and debris can be intercepted and collected, and the liquid can be leaked out, thereby reducing pollution to the outside world, and at the same time, it can prevent the debris from further splashing and causing harm to the human body. When cleaning is required, the positioning hole 30 is disengaged from the positioning pin 31, and then the filter cover 24 is moved forward appropriately to discharge the collected material. When it is moved further forward, the buckle 29 is disengaged from the front support frame 6 and the filter cover 24 can be completely removed.
所述过滤罩24左上部和右上部分别向上贯穿有开口32，两所述开口32延边缝制固定有上弹性带33，所述上弹性带33前部缝制固定有能够开合的布盖34，所述布盖34采用弹性的透气透水面料织成，所述布盖34后部固定有多个挂钩35，所述上弹性带33后部固定有多个挂环36，各所述挂钩35在布盖34的弹性拉扯作用下与各挂环36相挂接，所述布盖34利用挂钩35与挂环36的挂接实现对开口32的盖合。The filter cover 24 has openings 32 extending upward at the upper left and right parts respectively, and upper elastic bands 33 are sewn and fixed along the edges of the two openings 32. A cloth cover 34 that can be opened and closed is sewn and fixed to the front of the upper elastic bands 33. The cloth cover 34 is made of elastic, breathable and water-permeable fabric. A plurality of hooks 35 are fixed to the rear of the cloth cover 34, and a plurality of hanging rings 36 are fixed to the rear of the upper elastic bands 33. Each of the hooks 35 is connected to each of the hanging rings 36 under the elastic pulling action of the cloth cover 34, and the cloth cover 34 covers the openings 32 by connecting the hooks 35 with the hanging rings 36.
进一步的，当利用过滤罩24对碎屑进行收集时，使得开口32向上，此时利用挂钩35与挂环36的挂接实现布盖34对开口32盖合，从而保证对飞溅的碎屑的拦截效果，而打开布盖34后通过开口32能够方便的观察到前反光镜10和孔洞周围的状况，当需要排出碎屑时，短暂解除前支撑架6与钻进表面的抵触，然后对外支撑筒5进行转动，使得开口32向下，然后打开布盖34即可方便的将碎屑排出。Furthermore, when the filter cover 24 is used to collect debris, the opening 32 is directed upwards, and the hook 35 and the hanging ring 36 are connected to realize the cloth cover 34 covering the opening 32, thereby ensuring the interception effect of the flying debris. After opening the cloth cover 34, the conditions around the front reflector 10 and the hole can be conveniently observed through the opening 32. When the debris needs to be discharged, the front support frame 6 is temporarily released from the interference with the drilling surface, and then the outer support tube 5 is rotated so that the opening 32 is directed downwards, and then the cloth cover 34 is opened to conveniently discharge the debris.
所述钻机1的转轴通过螺栓可拆卸地同轴紧固连接有钻杆2，所述钻杆2前部通过螺栓可拆卸地同轴紧固连接有钻头3，所述钻机1前部相较于其转轴圆周等角度固定有三个插块37，所述插块37采用永磁铁制成，各所述插块37共同插接有套筒38，所述套筒38为能够与永磁铁相磁性吸附的金属材料制成，所述套筒38与插块37相磁性吸合，所述钻杆2能够相较于套筒38转动，所述套筒38前端固定有螺旋状的压缩弹簧39，所述套筒38和压缩弹簧39与钻杆2相间隙插接，所述压缩弹簧39与外支撑筒5后端相搭触。The rotating shaft of the drilling rig 1 is coaxially fastened with a drill rod 2 in a detachable manner by bolts, and the front part of the drill rod 2 is coaxially fastened with a drill bit 3 in a detachable manner by bolts. Three plug blocks 37 are fixed at the front part of the drilling rig 1 at equal angles relative to the circumference of its rotating shaft. The plug blocks 37 are made of permanent magnets, and each of the plug blocks 37 is commonly plugged with a sleeve 38. The sleeve 38 is made of a metal material that can be magnetically attracted to the permanent magnet. The sleeve 38 is magnetically attracted to the plug blocks 37, and the drill rod 2 can rotate relative to the sleeve 38. A spiral compression spring 39 is fixed to the front end of the sleeve 38. The sleeve 38 and the compression spring 39 are gap-connected with the drill rod 2, and the compression spring 39 is in contact with the rear end of the outer support tube 5.
进一步的，利用压缩弹簧39的弹性斥力，能够使得外支撑筒5具有向前移动的趋势，从而便于前支撑架6抵于钻进表面或者前支撑架6隔着前弹性带25抵于钻进表面，而通过套筒38与插块37的配合，能够方便得对套筒38和压缩弹簧39一同更换。Furthermore, by utilizing the elastic repulsive force of the compression spring 39, the outer support tube 5 can have a tendency to move forward, thereby facilitating the front support frame 6 to press against the drilling surface or the front support frame 6 to press against the drilling surface through the front elastic band 25. By cooperating with the sleeve 38 and the insert block 37, the sleeve 38 and the compression spring 39 can be easily replaced together.
