Description

Technical Field

[0001] This utility model relates to the field of buffer strip technology, specifically a high-efficiency buffer strip with a multi-level buffer structure. Background Technology

[0002] In many industrial production and material transportation sectors, such as mining, port loading and unloading, coal transportation, and material transfer in manufacturing, impacts are inevitable during material transport. For example, on a belt conveyor in a mine, large pieces of ore falling from a height onto the conveyor belt cause significant impact on the belt and its supporting structure. Similarly, during port loading and unloading, the frequent placement of heavy objects on the conveyor belt also generates strong impacts. These impacts not only easily lead to wear and tear on the conveyor belt, shortening its service life, but also transmit to other components of the conveying equipment, causing equipment failures, increasing maintenance costs, and affecting the normal operating efficiency of the entire production and transportation system.

[0003] Traditional buffer strips mostly use a single buffer material or a relatively simple structural design, which can only provide limited buffering capacity. For example, common buffer strips made primarily of rubber will quickly reach their deformation limit when faced with a large impact. To achieve a multi-level buffering effect, they are spliced ​​together. However, in actual use, some existing buffer strips have complex splicing methods, often using bolts for connection. Although the bolts are relatively strong, they require tools for installation and disassembly, making the operation cumbersome. Furthermore, the bolts are prone to rust and corrosion, affecting subsequent disassembly and maintenance. The overall splicing process is time-consuming, labor-intensive, and consumes a lot of manpower and time costs, which is not conducive to rapid installation and subsequent maintenance and replacement, thus affecting their practicality and widespread application in actual production.
