[0002] Cable protection devices are equipment used to protect cables from damage and external environmental factors. They can be used in various scenarios and applications, including industry, construction, energy, communications and transportation. They are usually protective devices such as various forms of jackets, sheaths, protective tubes, shields or insulation layers. They provide cable safety protection by wrapping, covering or isolating cables. They are designed to protect cables from damage, extend their service life and ensure safe operation.

[0003] However, in actual use, traditional coal mining machine cable protection devices may cause great wear and tear on the cables because the coal mining machine needs to move to different positions to work. After long-term wear, the wires inside the cables may be exposed, which may bring safety risks. In addition, traditional coal mining machine cable protection devices are mostly a whole, so it will cause great inconvenience for the staff to put the coal mining machine cables into the protection device, reducing the practicability of the protection device.
