A kind of adjustable trestle for installing touch screen in engineering machinery driving cabinTechnical field
The present invention relates to a kind of adjustable trestle installing touch screen for engineering machinery driving cabin, be specifically related to a kind of adjustable trestle installing touch screen for cab of rotary drilling rig.
Background technique
Cab of rotary drilling rig space is less, touch screen used needs to be placed in suitable operating position, due to build and the operating habit difference thereof of different operating personnel, the height of touch screen and towards sometimes needing to carry out appropriateness adjustment, for this reason, the adjustable trestle of the bright a kind of installation touch screen do not taken up space of beard and hair.
Summary of the invention
For above-mentioned prior art Problems existing, object of the present invention provides a kind of installation supporting frame of touch screen, neither takies cab space, can meet again the individual demand of rotary drilling rig operator, carries out appropriateness adjustment to the dimensional orientation of touch screen.
The present invention is achieved in that
A kind of arbitrarily angled adjustable trestle for installing touch screen in engineering machinery driving cabin, comprise the first U-shaped support and the second U-shaped support, the back side of shell of described touch screen is bolted on the second U-shaped support, second U-shaped support and the first U-shaped support by pin bolt and guide hinged, second U-shaped support both sides are provided with oval hole, second knurled screw screw thread is installed in the oval hole of the second U-shaped support both sides, first U-shaped support and the second U-shaped support can relatively rotate several angle around pin bolt, both sides second knurled screw is twisted to first with hand behind location, two U-shaped supports carry out fastening, first U-shaped support underrun holding down bolt connects with the top board of upper support base, first U-shaped support bottom surface is provided with oval hole, make it can turn an angle around holding down bolt, 3rd knurled screw screw thread is installed in the oval hole of the first U-shaped support, locates stubborn 3rd knurled screw of rear hand and carries out fastening to the first U-shaped support, top board, described upper support base by casing pipe sleeve above lower support base, first knurled screw screw thread is installed in the base hole of support base, mutually can rotate between sleeve pipe and lower support base, also can adjust upper-lower height, twist the first knurled screw with hand when must fix and carry out fastening, flange bottom described lower support base is provided with threaded mounting hole, by bolt described support is fixed on the appropriate location on bottom plate of driving cab.A whole set of support volume is little, substantially covers the behind at touch screen.
It is further preferred that described upper support base top has the threading hole that supply lines passes.
The invention has the beneficial effects as follows: a whole set of support volume is very little, substantially covers the behind at touch screen, does not separately take up space.The electrical equipment wiring harness of touch screen, from the bottom threading of lower support base, is then drawn from the threading hole on upper support tube cover for seat pipe top, then through touch screen socket hole access behind, wire harness is substantially hidden and do not expose.The present invention is simple and reliable for structure, it is little to take up room, and can arbitrarily angledly adjust, both artistic and practical.
Accompanying drawing explanation
Fig. 1 is the plan view of the embodiment of the present invention;
Fig. 2 is the A direction view of embodiment of the present invention Fig. 1.
Reference character in above-mentioned figure:
1 lower support base, 2 first knurled screws, support base on 3,4 pin bolts, 5 guidees,
6 second knurled screws, 7 the 3rd knurled screws, 8 holding down bolts, 9 first U-shaped supports, 10 second U-shaped supports, 11 touch screens
Embodiment
Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
As shown in Figure 1 and Figure 2, in the embodiment of the present invention, touch screen 11 back side of shell is bolted on the second U-shaped support 10; Second U-shaped support 10 both sides are all provided with the oval hole of certain arc length, second U-shaped support 10 and the first U-shaped support 9 by pin bolt 4 and guide 5 hinged, make two supports can relatively rotate several angle around pin bolt 4, second knurled screw 6 screw thread is installed in the oval hole of the second U-shaped support 10 both sides, and guide 5 is twisted both sides second knurled screw 6 with hand after locating in oval hole and carried out fastening to both; First U-shaped support 9 underrun holding down bolt 8 connects with the top board of upper support base 3, first U-shaped support 9 bottom surface is also provided with an oval hole, 3rd knurled screw 7 screw thread is installed in the oval hole of the first U-shaped support 9, make it can turn an angle around holding down bolt 8, locate stubborn 3rd knurled screw 7 of rear hand and carry out fastening to both; Upper support base 3 by casing pipe sleeve above lower support base 1, can mutually rotate between the two, also can adjust upper-lower height, the first knurled screw 2 screw thread is installed in the base hole of support base 3, twists the first knurled screw 2 carry out fastening when must fix with hand; Flange bottom lower support base 1 is bolted on the appropriate location on bottom plate of driving cab.Touch screen is arranged on this support just can carry out appropriateness adjustment comprehensively to its orientation as required, and a whole set of support volume is very little, substantially covers the behind at touch screen, does not separately take up space.The electrical equipment wiring harness of touch screen, from the bottom threading of lower support base 1, is then drawn from the threading hole on upper support base 3 sleeve pipe top, then through touch screen socket hole access behind, wire harness is substantially hidden and do not expose.
The present invention is simple and reliable for structure, easy to operate, low cost of manufacture, both artistic and practical.
