[0002] As a highly efficient material conveying equipment, crawler belt conveyors are widely used in mines, construction sites, ports and docks, and are particularly suitable for long-distance, continuous material conveying. However, as the conveying distance increases, the belt support frame of the crawler belt conveyor also grows accordingly, making it difficult to effectively control the center of gravity of the equipment on the crawler chassis. This problem is particularly prominent in complex road conditions, such as uneven ground and ramps. Under these conditions, it is difficult to control the balance of crawler belt conveyors when moving or climbing, and they are prone to safety hazards such as rollover and slippage.

[0003] In addition, the instability of the center of gravity will also affect the normal operation of the belt conveyor; during the conveying process, due to the shift of the center of gravity, the belt may deviate, slip, etc., seriously affecting the conveying efficiency and the service life of the equipment. At the same time, this also increases the difficulty and cost of equipment maintenance. Therefore, a new type of crawler belt conveyor is urgently needed that can specifically cope with climbing scenarios and improve its stability. Utility Model Content
