Abstract

The invention relates to a crawler-type excavator. The crawler-type excavator comprises a lower walking crawler belt 1, a rotary platform 1.2, a cab 1.1, a counter weight 1.3 ad a working device, wherein the rotary platform 1.2 is arranged on the lower walking crawler belt 1, the cab 1.1 and the counter weight 1.3 are installed on the rotary platform 1, and the working device is arranged in frontof the rotary platform; and the working device comprises a movable arm 1.4, a bucket rod 1.5 and a bucket 1.6, and the lower walking crawler belt is composed of a driving wheel 2, a tensioning wheel 3, walking wheels 4, carrier rollers 5, a tensioning device 6, a high-pressure air injection device 7 and a crawler frame 8; and the crawler-type excavator further comprises a defect detection component, and the defect detection component is used for detecting a driving block of the crawler belt is abraded and deformed or not, so that the working performance of the crawler belt of the excavator areensured.

Description

Technical field [0001] The invention belongs to the field of excavators, and relates to a crawler excavator. Background technique [0002] As a key component of the walking mechanism of a crawler excavator, the crawler piece is large in quantity, heavy, and extremely carrying capacity. The weight of the excavator and the mining reaction will be distributed on the crawler, which has always been a high concern for mine procurement and quality control departments. The product. At the same time, because it is in direct contact with the ground, ore, mud, sand, sewage and other pit materials, the crawler not only has high requirements for strength and toughness, but also requires high wear resistance and corrosion resistance. Especially for large excavator crawlers, due to the heavy weight of the large machine, the large bucket capacity and the large digging force, the performance requirements of the large excavator crawler are high, and there is currently no mechanical wear detection...
