Description
Technical field
The present invention relates to running gear, specifically a kind of running gear that can adapt to various pavement conditions.
Background technology
Traveling gear in current various machineries can only carry out the work on plane ground, when run into the ground of various differing tilt angles, slope or hollow ground time, the inclination of whole walking mechanism can be caused, the serious horizontal service position affecting mechanism, even cause overturning.
In order to overcome above-mentioned defect, I discloses a kind of inclined-plane traveling gear with CN103231636A, this mechanism adopts the tilt rows walking system be made up of four-bar mechanism, hydraulic actuating cylinder, gear, in the course of the work, a limit of Hydraulic Cylinder four-bar mechanism realizes the joint motions of telescoping mechanism, thus opens certain angle, realizes the adjustment of mechanism to ground distance, reach the change adapting to ground-angle in real time and tilt, the working face of maintaining body is horizontal always.The traveling gear structure of this structure is comparatively complicated, carrys out the distance between adjusting mechanism and ground by the joint motions of telescoping mechanism, and precision is not high, still can there is the problem of mechanism tilts.
Summary of the invention
The object of the invention is for overcoming above-mentioned defect, and disclose a kind of running gear of various pavement conditions of adapting to, this device adapts to the change of ground-angle, to meet the horizontal operation requirement of moving device mainly through the travel angle of modifier.
The technical scheme realizing the object of the invention is:
A kind of running gear that can adapt to various pavement conditions, comprise main shaft, gear and road wheel, unlike the prior art: be provided with slider-crank mechanism, bidirectional ratchet mechanism, gear is connected with main shaft, slider-crank mechanism is by slide block, tooth bar and rocking bar composition, rocking bar upper end and main shaft are socketed, lower end is connected with road wheel, slide block is connected with main shaft, and be socketed on tooth bar, slide up and down along tooth bar, tooth bar upper end and gear are abutted against, lower end is connected with road wheel, bidirectional ratchet mechanism is fixed on fixed transverse rod, be connected with gear, the torsion spring be connected with gear is provided with in main shaft one end, gear realizes the contact with tooth bar by torsion spring.
Described rocking bar is the first rocking bar and the second rocking bar, and the first rocking bar upper end and main shaft are socketed, and lower end is connected with the second rocking bar upper end, second rocking bar lower end is connected with the revolute of road wheel, by slide block sliding up and down on tooth bar, drive rocking bar motion, realize the change that main shaft leaves ground distance.
Described bidirectional ratchet mechanism is connected with gear by stay cord, by controlling the sense of motion of stay cord, pulls gear to rotate, and band movable slider, along the up-and-down movement of tooth bar, realizes the height control that main shaft leaves ground distance.
The invention has the beneficial effects as follows, solve because terrain slope or the uneven running gear caused tilt the problem of even overturning, utilize stay cord manual operation, the distance that main shaft leaves ground is changed by slider-crank mechanism, to adapt to the change of various state of ground, ensure that the groundwork plane of running gear is horizontal, operate light, structure simple, it is convenient to realize.

Pull gear 3 to rotate by stay cord 2, the moving displacement of band carry-over bar 5, realizes the up-and-down movement of tooth bar 5;
Road wheel 9 is connected in the revolute of the second rocking bar 8 and tooth bar 5, by the up-and-down movement of tooth bar 5, band movable slider 6, first rocking bar 7 and the second rocking bar 8 move, the position of the revolute be connected on road wheel 9 is moved up and down, road wheel 9 is driven to move up and down, make running gear adapt to sloping floor, realize the change that main shaft 1 leaves ground distance;
Controlled the sense of motion of stay cord 2 by the bidirectional ratchet mechanism 10 be fixed on fixed transverse rod 11, realize the height control that main shaft leaves ground distance.
