Description

Technical Field

[0001] The utility model belongs to the technical field of elevator buffers, in particular to a polyurethane elevator buffer adapted to extreme loads. Background Art

[0002] Polyurethane elevator buffers that adapt to extreme loads are a key safety component that plays a vital role in elevator systems. Polyurethane is a material that is widely used because of its high elasticity, impact resistance, and good pressure resistance. Polyurethane buffers are light in weight, simple to install, maintenance-free, and have good buffering effects. The buffering process is noiseless, spark-free, explosion-proof, safe, reliable, and stable. The response time of polyurethane elevator buffers is short, generally between a few milliseconds and tens of milliseconds. This means that in emergency situations such as overspeeding or free fall in the elevator, the polyurethane buffer can quickly provide resistance, slow down the impact of the elevator car, and protect the safety of passengers and equipment. Due to the fast response time of the polyurethane buffer, it can adapt to extreme loads and has a higher degree of safety.

[0003] Since the polyurethane buffer is mainly made of polyurethane as raw material, polyurethane will age during use, and the aging of polyurethane will lead to a decrease in the buffering effect on the elevator car; the existing polyurethane buffer is troublesome to disassemble and assemble, and it is not convenient for operators to replace it, which increases the workload of operators and reduces the disassembly and assembly efficiency.
