Problems solved by technology

The high-strength crawler tensioning mechanism is not easy to deform when it bears a large load, but the structure is complicated, and it is very inconvenient to use, maintain, assemble and disassemble
Compared with the high-strength crawler tensioning mechanism, the low-strength crawler tensioning mechanism has the advantages of less complicated structure and more convenient use, maintenance, and loading and unloading, but it is easy to deform when bearing a large load, or cannot play a role. Effective tensioning, or the tensioning direction will be tilted and sideways, causing the track to deform, resulting in increased internal force, wear, and vibration during the movement of the track, which is not conducive to the use of the track running mechanism
It can be seen that the existing high-strength and low-strength crawler tensioning mechanisms each have some shortcomings. How to combine the advantages of the two is a problem that needs to be solved at present

Abstract

The invention discloses a modularized track tensioning mechanism and a mounting and dismounting method thereof. The track tensioning mechanism comprises a U-shaped outer frame, the outer frame is fixedly connected with a fixing frame, the outer frame comprises two side frames, and the two side frames are connected through a connecting frame; a tensioning shaft assembly is installed between the two side frames, a tensioning wheel is rotatably installed on a tensioning shaft assembly and surrounded by three surfaces of the outer frame, and the two ends of the tensioning shaft assembly penetrate through and stretch out of the two side frames and can slide in sliding grooves of the two side frames; a screw rod is movably screwed on a connecting frame in a penetrating manner; one end, extending into the outer frame, of the screw rod is detachably connected with the tensioning shaft assembly; and when the tensioning shaft assembly slides to the position needing to be tensioned and is connected with the end, extending into the outer frame, of the screw rod, the screw rod is fixed by a positioning pin installed on the outer frame in a penetrating mode. The mechanism can bear a large load, and is high in strength, simple in structure and convenient to use, maintain, assemble and disassemble.

Description

technical field [0001] The invention relates to a tensioning mechanism of a crawler vehicle, in particular to a modularized crawler tensioning mechanism and its installation and disassembly method. Background technique [0002] The tensioning mechanism is an indispensable part of the crawler running mechanism. Its function is to make the crawler belt tighten or loosen due to its own movement or structural changes, so that the crawler running mechanism can successfully complete the task or adapt to diverse environments. Existing track tensioning mechanisms can be classified into high-strength and low-strength types according to different application occasions and loads. The high-strength crawler tensioning mechanism is not easy to deform when it bears a large load, but its structure is complicated, and it is very inconvenient to use, maintain, assemble and disassemble. Compared with the high-strength crawler tensioning mechanism, the low-strength crawler tensioning mechanism...
