Abstract
The utility model discloses a walking device suitable for various road conditions. The walking device comprises a spindle, a gear and a walking wheel. The walking device is characterized in that a slider-crank mechanism and a two-way ratchet mechanism are arranged, the gear is connected with the spindle, the slider-crank mechanism is composed of a slider, a rack and a rocker, the upper end of the rocker is connected with the spindle in a sleeved mode, the lower end of the rocker is connected with the walking wheel, the slider is connected with the spindle, the rack is sleeved with the slider, the slider slides up and down along the rack, the upper end of the rack is connected with the gear in an abutting mode, the lower end of the rack is connected with the walking wheel, the two-way ratchet mechanism is fixed to a fixing cross bar and connected with the gear, a torsion spring connected with the gear is arranged at one end of the spindle, and the gear makes contact with the rack through the torsion spring. The walking device has the advantages that the problem that the walking device inclines and even is turned over due to the fact that the ground inclines or is uneven is solved, manual operation is conducted through a pull rope, the distance from the spindle to the ground is changed through the slider-crank mechanism to make the walking device suitable for the change of various ground states, it is guaranteed that the main working plane of the walking device is located at the horizontal position, and the walking device is simple in operation, simple in structure and convenient to realize.
Description
Technical field
The utility model 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, in the time 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 made up 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 the adjustment of mechanism to 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, carrys out the distance between adjusting mechanism and ground by the joint motions of telescoping mechanism, and precision is not high, the problem that still can exist mechanism to tilt.
Utility model content
The purpose of this utility model is for overcoming above-mentioned defect, and discloses a kind of running gear that can adapt to various pavement conditions, and 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 utility model object 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 socket, 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, be provided with the torsion spring being connected with gear in main shaft one end, 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, realizes the height control of main shaft built on stilts distance.
The beneficial effects of the utility model are, solve due to the tilt problem of even overturning of terrain slope or the uneven running gear causing, utilize stay cord manual operation, change the distance of main shaft built on stilts by slider-crank mechanism, to adapt to the variation of various states of ground, guarantee that the groundwork plane of running gear is horizontal, operate light, simple in structurely, it is convenient to realize.
