The walking device comprises a main shaft, a gear and a walking wheel, and is characterized in that the walking device is provided with a crank slide block mechanism and a two-way ratchet wheel mechanism, the gear is connected with the main shaft, the crank slide block mechanism consists of a slide block, a rack and a rocker rod, the upper end of the rocker rod is sheathed and connected with the main shaft, the lower end of the rocker rod is connected with the walking wheel, the slide block is connected with the main shaft, is sheathed on the rack and upwards and downwards slides along the rack, the upper end of the rack is in leaning connection with the gear, the lower end of the rack is connected with the walking wheel, the two-way ratchet wheel mechanism is fixedly arranged on a fixed transverse rod and is connected with the gear, one end of the main shaft is provided with a torque spring connected with the gear, and the gear realizes the contact with the rack through the torque spring. The walking device has the beneficial effects that the problem of inclination or even turnover of the walking device caused by ground inclination or unevenness is solved, the manual operation is realized by using a pulling rope, the distance of the main shaft from the ground is changed through the crank slide block mechanism for adapting to various road condition variations, the major work plane of the walking device is guaranteed to be positioned in the horizontal position, the operation is light and convenient, the structure is simple, and the realization is convenient.
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 running into the ground of ground, slope or hollow of various differing tilt angles, can cause the inclination of whole walking mechanism, the serious horizontal service position that affects mechanism, even causes overturning.
In order to overcome above-mentioned defect, I disclose a kind of inclined-plane traveling gear with CN103231636A, this mechanism adopts the tilt rows walking system being comprised of four-bar mechanism, hydraulic actuating cylinder, gear, in the course of the work, the joint motions of telescoping mechanism are realized on a limit of Hydraulic Cylinder four-bar mechanism, thereby open certain angle, realize mechanism to the adjustment of ground distance, reach the variation that real-time adaptation ground angle tilts, the working face of maintaining body is horizontal always.The traveling gear structure of this structure is comparatively complicated, and the joint motions by telescoping mechanism carry out the distance between adjusting mechanism and ground, and precision is not high, the problem that still can exist mechanism to tilt.
Summary of the invention
The object of the invention is for overcoming above-mentioned defect, and disclose a kind of running gear that can adapt to various pavement conditions, this device mainly adapts to the variation of ground angle by the travel angle of modifier, to meet the horizontal operation requirement of moving device.
The technical scheme that realizes 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 form, rocking bar upper end and main shaft socket, lower end is connected with road wheel, slide block is connected with main shaft, and be socketed on tooth bar, along tooth bar, slide up and down, 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, in main shaft one end, be provided with the torsion spring being connected with gear, gear is realized and the contacting of tooth bar by torsion spring.
Described rocking bar is the first rocking bar and the second rocking bar, the first rocking bar upper end and main shaft socket, and lower end is connected with the second rocking bar upper end, the second rocking bar lower end is connected with the revolute of road wheel, sliding up and down by slide block on tooth bar, drives rocking bar motion, realizes the change of main shaft built on stilts distance.
Described bidirectional ratchet mechanism is connected with gear by stay cord, by controlling the sense of motion of stay cord, pulls gear rotation, and the up-and-down movement with movable slider along tooth bar is realized the height of main shaft built on stilts distance and controlled.
The invention has the beneficial effects as follows, solved due to the tilt problem of even overturning of terrain slope or the uneven running gear causing, utilize stay cord manual operation, by slider-crank mechanism, change the distance of main shaft built on stilts, to adapt to the variation of various states of ground, the groundwork plane that guarantees running gear is horizontal, and operates light, simple in structurely, and it is convenient to realize.

The specific embodiment
With reference to Fig. 1-2, a kind of running gear that can adapt to various pavement conditions, by main shaft 1, stay cord 2, gear 3, torsion spring 4, tooth bar 5, slide block 6, the first rocking bar 7, the second rocking bar 8, road wheel 9, bidirectional ratchet mechanism 10, fixed transverse rod 11 forms, gear 3 is located at main shaft 1 top, in main shaft 1 one end, be provided with the torsion spring 4 being connected with gear 3, in gear 3 one sides, be provided with tooth bar 5, gear 3 is realized and the contacting of tooth bar 5 by torsion spring 4, the first rocking bar 7 upper ends and main shaft 1 socket, lower end is connected with the second rocking bar 8 upper ends, the second rocking bar 8 lower ends are connected with the revolute of road wheel 9, slide block 6 is connected with main shaft 1, and be socketed on tooth bar 5, tooth bar 5 upper ends and gear 3 are abutted against.
By stay cord 2, pull gear 3 rotations, with the moving displacement of carry-over bar 5, realize 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, the first rocking bar 7 and the second rocking bar 8 motions, the position that is connected to the revolute on road wheel 9 is moved up and down, drive road wheel 9 to move up and down, make running gear adapt to sloping floor, realize the change of main shaft 1 built on stilts distance;
By being fixed on the sense of motion of the bidirectional ratchet mechanism 10 control stay cords 2 on fixed transverse rod 11, realize the height of main shaft built on stilts distance and control.
