A kind of clear soil device for tunnel excavation machineTechnical field
The present invention relates to a kind of tunnel excavation pick device, particularly to a kind of clear soil device for tunnel excavation machine.
Background technology
Tunnel be build in underground, under water or in massif, place an iron railway or build highway for the current building of motor vehicles.Mountain tunnel, submerged tunnel and city tunnel three major types can be divided into according to its position.That passes through from the mountain ridge or hills for reducing the distance and avoid steep gradient is referred to as mountain tunnel；For river crossing or straits from river or seabed pass through be referred to as submerged tunnel；It is referred to as city tunnel by metropolitan needs what Urban Underground passed through for adapting to railway.
The excavation method in tunnel is divided into cut and cover method and subsurface excavation method, and cut and cover method is used for shallow tunnel or city railway tunnel, and the multiplex subsurface excavation method of mountain ridge railway tunnel.Divide by excavated section size, position, have partial excavation method and full face tunneling method.Use drilling and blasting method the most extensive in stone homogenous rock stratum, use development machine directly to excavate and the most gradually promote.Use shield method excavation more in soft geology.
Drilling and blasting method is jewel hole on tunnel scar, and loads explosive blasting, the construction method being molded by tunnel excavation with full face tunneling or partial excavation etc..Full face tunneling method and partial excavation method are the methods that drilling and blasting method excavation is conventional, but constructing tunnel is the most complicated, time be commonly encountered all difficulties situation, such as major fault, drift sand, expansion stratum, solution cavity, a large amount of water bursts etc., still need and take corresponding measure.
Shield method is to use shield as the method for tunnel construction of construction equipment, and shield method is applicable to broken ground, construction safety, and few to ground disturbance, control country rock periphery is accurate, seldom backbreaks.
Tunnel boring machine method is on whole tunnel cross-section, by the method for the gear construction of driving continuously.
Present stage is when tunneling, the earth dug out, needing to be transported by other conveying arrangement, this needs to put into substantial amounts of manpower and materials, adds cost, when excavating, owing to earth falls at headstock, making troubles to moving ahead of vehicle, the earth transporting this part is, due to the restriction of tunnel space, bring inconvenience to operation.
Summary of the invention
The invention aims to solve that present stage earth cleaning after cutting the earth in tunnel is inconvenient, cleaning time the shortcoming that wastes time and energy, and a kind of clear soil device for tunnel excavation machine proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of clear soil device for tunnel excavation machine, it is characterized in that: include vehicle frame, longitudinally connected transmission band below vehicle frame, it is all connected with the first baffle plate in the both sides of transmission band, hinged shovel board on two the first baffle plates on front side of transmission band, hinged shovel board and transmission band corresponding matching, the most hinged first oil cylinder in the outside of shovel board, each first oil cylinder is all hinged on vehicle frame.
On the basis of technique scheme, can there is a technical scheme further below:
Described shovel board is trapezoidal plate, was provided with at the upper end of shovel board and the slot to make way of described transmission band corresponding matching, connects a second baffle in the shovel board of slot to make way both sides respectively.
It is provided with one group of teeth going to the bottom of described shovel board, the most hinged push pedal in the front side of each described second baffle, the shovel board outside each push pedal is also respectively connected with second oil cylinder hinged with it.
Described second baffle is folded structure.
Described vehicle frame in described shovel board both sides is equipped with an earth scraping device, earth scraping device includes the connecting plate being connected on the downside of vehicle frame, connecting plate passes through fixed plate connecting upright pole, be rotatably assorted in vertical rod connection rotating plate, flap connects scraper plate, the most hinged 3rd oil cylinder on scraper plate, the 3rd oil cylinder is fastened on connecting plate also by hinged seat.
It is provided with one group of scraping teeth in the downside of described scraper plate, is also connected with extension plate in the outside of scraper plate.
It is provided with the sleeve being rotatably assorted with described vertical rod in the side of described flap, the vertical rod on the upside of sleeve is provided with ring flange, the vertical rod between sleeve and ring flange is socketed buffer spring.
Described 3rd oil cylinder rotates in perpendicular around described hinged seat, the 3rd oil cylinder with the pin joint of described scraper plate for fulcrum at horizontal rotation in surface.
It is an advantage of the current invention that: the soil that this device goes out tunneling power blader, the rear side being transported to tunneling machine by shovel board, earth scraping device and transmission band is focused on, and makes to remain before tunneling machine clean state, and earth cleaning is convenient, speed is fast, time saving and energy saving.

Detailed description of the invention
In order to make the present invention clearer, describing this device in detail below in conjunction with accompanying drawing, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of clear soil device for tunnel excavation machine that the present invention provides, including vehicle frame 1, longitudinally connected transmission band 2 below vehicle frame 1, transmission band 2 uses belt-type transmission band, be all connected with the first baffle plate 3 in the both sides of transmission band 2, the upside of the first baffle plate 3 is higher than the top edge of transmission band 2, and the earth that two the first baffle plates 3 are prevented from transmission band 2 drops.
Hinged shovel board 5 on two the first baffle plates 3 on front side of transmission band 2, hinged shovel board 5 and transmission band 2 corresponding matching, shovel board 5 is trapezoidal plate, it is provided with one group of teeth 6 going to the bottom of described shovel board 5, it was provided with at the upper end of shovel board 5 and the slot to make way 5a of described transmission band 2 corresponding matching, transmission band 2 both sides vehicle frame 1 is respectively articulated with first oil cylinder 4, the piston rod of each first oil cylinder 4 is all hinged in shovel board 5, and under the effect of the first oil cylinder 4, shovel board 5 can rotate in perpendicular for fulcrum with it with the pin joint of the first baffle plate 3.
The shovel board 5 of described slot to make way 5a both sides connects a second baffle 7 respectively, second baffle 7 is folded structure, two second baffles 7 form horn structure, and the interior trisection of each second baffle 7 is all correspondingly arranged at the corresponding side of slot to make way 5a, outer trisection extends to the front side of shovel board 5.In the most hinged push pedal 8 in the front side of each described second baffle 7, second oil cylinder 9 hinged with it it is also respectively connected with in shovel board 5 outside each push pedal 8, under the effect of the second oil cylinder 9, each push pedal 8 all can rotate at the upper side of shovel board 5, for the soil outside shovel board 5 is pushed away to inner side.
