Description

Technical Field

[0001] The utility model belongs to the technical field of underground operation, and in particular relates to an underground operation auxiliary device. Background Art

[0002] Underground work refers to work carried out in underground spaces such as mines, underground projects or shafts. This working environment is particularly dangerous and complex because the underground working space is narrow, the light is insufficient, the ventilation is poor, and there are safety hazards such as landslides, roof falls, water gushing, and gas.

[0003] When mining operations are carried out underground in a mine, due to the poor stability of the mine roof and side walls, collapse accidents are prone to occur. The roof and side walls need to be supported to prevent the mine from collapsing. The internal space of the mine is small. In order to facilitate carrying and transportation, hydraulic supports are used to support and fix the mine roof. During the use of hydraulic supports, they need to be used for a long time. The hydraulic supports are exposed to greater pressure and hydraulic oil leakage may occur, resulting in insufficient system pressure and affecting the normal operation of the equipment. The hydraulic oil needs to be replaced regularly and the sealing performance needs to be checked. The problem with the above technology is that during the long-term use of the hydraulic supports, hydraulic oil leakage may occur, resulting in a decrease in the load-bearing capacity of the hydraulic supports.
