Description

Technical Field

[0001] The utility model relates to the technical field of crawler track tensioning, in particular to a novel tensioning mechanism for a crawler track beam. Background Art

[0002] As tracked self-propelled vehicles are used, their bushings and track connecting pins will wear out, causing the track tension to decrease. The track tension should also be adjusted appropriately under different working conditions, such as the hardness of the ground, the distribution of sand and gravel, etc., to extend its service life.

[0003] And in the application document with publication number CN218343625U, a new type of track beam tensioning mechanism is mentioned. This mechanism realizes pure mechanical structure adjustment of track tensioning through a simple structure, and the adjustment degree can be observed in real time. It can be well adapted as a backup adjustment mechanism or an auxiliary adjustment mechanism for track tensioning, and is especially suitable for crawler self-propelled vehicles such as small excavators, making their chassis layout space more ample. However, there are still certain defects that need to be optimized. The specific defects are as follows: The tensioning structure is an integrated structure, and after damage, it needs to be completely replaced and repeatedly adjusted, which is cumbersome.

[0004] Therefore, it is particularly important to design a new tensioning mechanism for the crawler beam to change the above-mentioned technical defects and improve the overall practicality. Utility Model Content
