TECHNICAL FIELD
[0001] The utility model relates to an adjustable rubber track block structure and belongs to the excavator track structure technical field. BACKGROUND
[0002] At present, hydraulic excavators mostly use steel tracks to cope with bad road conditions, and the track plates are mostly "three-rib" form rolled steel track plates. But in the case where the walking road or work site is not allowed to be damaged, rubber track blocks need to be installed on the steel track plate to protect the road site. But the situation that needs to use rubber track blocks is not much, such as exhibition and some light municipal work, which leads to low utilization rate of customers' rubber track blocks, and because rubber track blocks cannot be driven on bad road conditions, the demand for disassembling rubber track blocks is more frequent.
[0003] The cost of a set of rubber track blocks is about 20,000 yuan, and if the versatility of rubber track blocks can be improved, the number of purchases of customers can be reduced, and the utilization rate of rubber track blocks can be improved.
