The mechanism comprises track frames, positioning pins, front connecting rods, widening oil cylinders, a lower vehicle frame and rear connecting rods, wherein a guide wheel is arranged at one end of each track frame, and a driving wheel is arranged at the other end of each track frame; a plurality of thrust wheels are arranged under each track frame; a caterpillar track is wound at the periphery of each track frame; bearing chain wheels are also arranged between each caterpillar track and a frame body; the track frames, the front connecting rods, the lower vehicle frame and the rear connecting rods are connected to form a parallelogram through pin shafts; a cylinder barrel end of each widening oil cylinder is hinged with the lower vehicle frame; a piston rod end of each widening oil cylinder is hinged with one track frame; and a locking shaft pin and a positioning pin hole are arranged on a convex corner of each front connecting rod. The mechanism avoids the sliding friction of the original structure, can ensure that the gravity center position of a transport state of a drilling rig is relatively reasonable at the same time, and can also be structurally implemented easily.
Description
Technical field
The present invention relates to rotary drilling rig crawler body technical field, especially a kind of crawler body gauge regulating mechanism.
Background technology
Rotary drilling rig is a kind of the most frequently used pile foundation construction equipment, is widely used in the pile foundation construction of the engineerings such as high speed railway, express highway, bridge, harbour, skyscraper.Rotary drilling rig one general configuration crawler body, and require the gauge of crawler body adjustable, for satisfying stability requirement, need the chassis gauge wider during work; For avoiding super wide, need the chassis gauge narrower during transportation.
Realize that at present mode that the chassis gauge regulates is shown in accompanying drawing 7 and accompanying drawing 8: four square beams of former lower vehicle frame 17 insert respectively in four square holes of left track frame 14, right-hand track chiain frame 15 and form the very little cooperation in gap, it is L that a former broadening oil cylinder 16(stroke is equipped with in each square beam the inside), the cylinder barrel end of former broadening oil cylinder 16 and former lower vehicle frame 17 are hinged, the rod end of former broadening oil cylinder 16 and left track frame 14, right-hand track chiain frame 15 are hinged respectively, expansion and the withdrawal of the flexible realization left and right sides track frame by cylinder piston rod.Accompanying drawing 7 is the full retracted state of piston rod, and gauge this moment minimum (size W), accompanying drawing 8 stretch out state, gauge maximum this moment (size W+2L) entirely for piston rod.
The shortcoming of this kind mode is: have cliding friction between the square beam of the vehicle frame at present of 1) working and the track frame square hole, because rig weight is very large, cause friction force very large, be easy to cause the scuffing of contact surface, can cause larger friction force after the scuffing; 2) upper body does not change with respect to chassis relative position on the rig fore-and-aft direction when crawler belt withdrawal and broadening, makes rig center of gravity when travelling position too forward.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides a kind of crawler body gauge regulating mechanism.
The technical solution adopted for the present invention to solve the technical problems is: a kind of crawler body gauge regulating mechanism, comprise track frame, locating dowel pin, front rod, the broadening oil cylinder, lower vehicle frame, rear connecting rod, track frame one end is equipped with guide wheel, one end is equipped with drive wheel, be provided with caterpillar wheel below the track frame, the track frame periphery is wound with crawler belt, also be provided with the holder sprocket wheel between crawler belt and the support body, track frame, front rod, lower vehicle frame, rear connecting rod is connected to form a parallelogram by bearing pin, broadening cylinder tube end and lower vehicle frame are hinged, broadening oil cylinder piston rod end and track frame are hinged, and the salient angle of front rod is provided with lock shaft pin and dowel hole.
The invention has the beneficial effects as follows that the present invention has avoided the cliding friction of original design, can make the center-of-gravity position of rig travelling position more reasonable simultaneously, also be easy on the structure realize.
