[0002] In the process of mining mineral resources, mine hoists play a crucial role in transporting personnel, materials, equipment, etc. However, there are significant safety hazards at the wellheads of mine hoists.

[0003] In the past, in some mines, the protective measures for wellheads were relatively simple and weak. Some only simply set up some temporary obstacles, such as ropes, wooden boards, etc. These obstacles are not only not firm but also difficult to effectively prevent people from accidentally approaching the wellhead.

[0004] Some other mines adopted fixed-structure guardrails, but these guardrails often had many problems. For example, their sizes and shapes are fixed, making it difficult to adapt to the actual situations of different wellheads, and they have poor versatility. The installation and disassembly processes are also relatively cumbersome, which is not conducive to the quick maintenance and operation of wellheads. With the continuous development of mine mining technology and the increasing requirements for work safety, there is an urgent need for a wellhead protection device with a reasonable structure, convenient installation, strong stability, good versatility, and capable of providing comprehensive protection.
