Description

Technical Field

[0001] The utility model relates to a crawler walking device, in particular to an anti-slip crawler walking device. Background Art

[0002] At present, crawler track walking is one of the most common forms of walking mechanisms of large equipment. Usually, the crawler track is wrapped around the outer periphery of the wheel frame, and walking is achieved by rotating the wheel body installed on the wheel frame. When using crawler tracks for walking, the ground contact area is large, the ground contact pressure is small, the cross-ditch performance is good, and the damage to fields and roads is small. However, when walking in an unbalanced state for a long time, the crawler track itself will also deform, thereby causing the tightness between it and the wheel body to decrease, which can easily cause the belt to come off. At present, the method to solve the belt coming off phenomenon is usually to increase the tightness between the crawler track and the wheel body by adding a tensioning wheel or changing the position of the tensioning wheel. This method requires stopping the machine for repairs, and the installation position and adjustment of the tensioning wheel require special personnel to design and operate, which seriously affects the progress of the work.

The wheel body is mounted on the wheel frame 4, and the crawler 1 is arranged on the periphery of the wheel body. The utility model also includes an adjustment component 8, through which the horizontal position of the driven wheel is adjusted, the tightness between the crawler and the wheel body is improved, and the belt is effectively prevented from coming off.

[0024] As a preferred embodiment, a driving wheel seat 3 is arranged on the upper part of the wheel frame 4, and driven wheel seats 5 are symmetrically arranged on both sides of the wheel frame 4. As a preferred solution, the wheel frame 4 is a horizontal frame body arranged in parallel from top to bottom, the driving wheel seat 3 is arranged in the central part of the upper frame body, and the driven wheel seats 3 are symmetrically arranged at both ends of the lower frame body. The driven wheel seat 3 is a hollow frame structure, and the driven wheel seat 3 is connected to the upper frame body through a rib plate. Preferably, the outer diameter of the driven wheel is larger than the diameter of the running wheel.

[0025] The wheel body includes a driving wheel 2, a driven wheel 6 and a running wheel 7. The driving wheel 2 is mounted on the driving wheel seat 3 and is mainly used for power transmission. The driving wheel 2 is linked to the external transmission shaft 9 through a connecting shaft, and the external transmission shaft is connected to the driving mechanism through a chain or a crawler track. Two driven wheels 6 are respectively mounted on the driven wheel seats 5, mainly to achieve power transmission and to tighten and prevent the crawler tracks from falling off. Several running wheels 7 are mounted at the bottom of the wheel frame 4, which play the main supporting and walking roles. The entire crawler walking device forms an isosceles triangle structure to achieve stable walking. The driven wheels at both ends are horizontally symmetrical, which improves the overall stability of the walking device.

[0026] The adjustment assembly 8 is horizontally mounted in the driven wheel seat 5, and includes an adjusting bolt 8-1 and a telescopic sleeve. The adjusting bolt 8-1 is connected to the connecting frame 8-3 of the driven wheel 6 through the telescopic sleeve to achieve horizontal movement of the driven wheel.

[0027] As another preferred embodiment, the telescopic sleeve in the adjustment component 8 includes a telescopic inner sleeve 8-4 and a telescopic outer sleeve 8-2, which are movably sleeved together. The outside of the telescopic outer sleeve 8-2 is fixedly connected to the driven wheel seat 5, and a connecting seat 8-5 is arranged inside the telescopic outer sleeve 8-2, and the inner wall of the connecting seat 8-5 is threaded. The adjusting bolt 8-1 is threadedly connected to the connecting seat 8-5, one end of the adjusting bolt 8-1 extends out of the telescopic outer sleeve 8-2, and the other end is fixedly connected to the end face of the telescopic inner sleeve 8-4.
