In constructing tunnel, usually can drill, so that construction can safe smoothly carrying out by means of multi-functional quick rig.The multi-functional rig of reading soon commonly used mostly is crawler type, many employing fixed connection structures between the driving frame of its creeper undercarriage and the vehicle frame of car load, its weak point be this structure to rough road surface bad adaptability, the rollover accident easily takes place.In addition, this type is subjected to the restriction of lifting device, and its lift height scope is little.
The utility model content
Technical problem to be solved in the utility model provides a kind of, multi-functional quick rig running gear that drillhole height scope big good to the road conditions comformability.
It is as follows to address the above problem the technical scheme that is adopted:
The utility model comprises creeper undercarriage and vehicle frame, it is characterized in that each hinged oil cylinder between the driving frame inboard of creeper undercarriage of described vehicle frame both sides and homonymy, and two oil cylinders arrange that along the vehicle frame bilateral symmetry it is hinged with the vehicle frame of homonymy respectively that two driving frame rear ends are arranged with central pin shaft about creeper undercarriage.
The oil circuit of two oil cylinders described in the utility model interconnects, and is provided with hydraulic lock in the oil circuit.
Good effect of the present utility model is as follows:
The utility model is improved on the prior art basis, is expert between vehicle frame and the car load vehicle frame, adopts hinge pin to connect, and has increased the pitching oil cylinder, the driving frame can be done with respect to vehicle frame swing up and down, and can adapt to ground-surface uneven situation preferably.In addition, the creeper undercarriage of this structure is installed on car load, can strengthen vehicle frame layback function, by the vehicle frame layback, makes the rig drill boom raise, and drillhole height strengthens.Adopt this device on the quick rig of crawler-type multifunctional, the stationarity of favourable raising complete machine reduces the rollover accident greatly.

The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Referring to accompanying drawing, in the present embodiment, driving frame 1 is to be connected on the vehicle frame (not expressing among the figure) with central pin shaft 7, it can swing up and down around central pin shaft 7, and the four-wheel one band system (comprising caterpillar wheel 2, track carrying wheel 3, guide wheel 4, drive wheel 5, crawler belt 6) that is fixed on the driving frame 1 swings along with the swing of driving frame 1.The power of swing comes from oil cylinder 10, and the piston rod front end of oil cylinder 10 is connected on the driving frame 1 with hinge pin under the oil cylinder 8, and the afterbody of oil cylinder 10 is connected on the vehicle frame (not expressing among the figure) with hinge pin on the oil cylinder 9.
When oil cylinder 10 elongations, driving frame 1 and device thereof can be to the bottoms, and 14 ° of maximum pendulum angles are seen accompanying drawing 2.
When oil cylinder 10 shortened, driving frame 1 and device thereof can upwards be put, and 14 ° of maximum pendulum angles are seen accompanying drawing 3.
On complete machine, left and right sides respectively has the running gear of cover symmetrical structure described in the utility model, the left and right sides running gear can move respectively, when the left and right sides floor level of complete machine is inconsistent, this device can adapt to surface state, keep the not run-off the straight of car body level, and the possibility that reduces to turn on one's side.
When the utility model uses on complete machine, can utilize the swing of aforementioned driving frame 1, make vehicle frame 11 swing back, and drive lifting device 12 upward movements, make rock drill 13 and drilling rod 14 positions raise, maximum horizontal drillhole height h can reach 5000mm, thereby under the situation of the scantling of structure that does not increase lifting device 12, satisfies the requirement of the railway tunnel construction worker method of regulation.Install and use situation on the complete machine, see accompanying drawing 4.
In the present embodiment, caterpillar wheel 2, track carrying wheel 3, guide wheel 4, crawler belt 6 are the excavating machine standard fitting, and drive wheel is design-calculated foundry goods voluntarily.
The matching used complete machine of the utility model institute adopts fluid motor-driven, double amount motor, and the big retarding ratio speed reducer, the speed of travel is 4km/h to the maximum.
Driving frame 1 is a welded structure, and the bearing of 10 times hinge pins 8 of oil cylinder is welded on the inboard of driving frame 1.Bilateral oil cylinder 10 also is arranged in the crawler belt inboard.
The oil circuit of two side cylinders 10 connects sees accompanying drawing 5, and hydraulic lock 15 shields, and vehicle frame leans forward out of control when preventing the a/b pipeline rupture.During the oil-feed of a mouth, the oil cylinder piston bar stretches out, the driving frame 1 front end bottom, vehicle frame 11 layback; During the oil-feed of b mouth, the withdrawal of oil cylinder piston bar is put on driving frame 1 front end, and vehicle frame 11 leans forward.The oil pipe of left and right sides oil cylinder interconnects, and when left and right sides Uneven road up time, fluid flows mutually, adapts to the ground-surface discrepancy in elevation automatically.
