Underground people carrier is a kind of trackless transportation equipment with high efficiency, low energy consumption and no pollution.In metallurgical mines, it is responsible for the transportation of underground rocks and ores.Due to the poor underground working conditions and humid environment, underground trucks often leak electricity, which directly endangers the lives and safety of production workers.Therefore, practical, reasonable and effective measures and methods must be taken to protect them in order to achieve the purpose of safe production.The following combines the actual use of underground personnel carriers to discuss several methods and measures for leakage protection of underground personnel carriers.

Underground personnel carriers work in harsh environments such as underground gun smoke, dust, dripping water on the roof, ground slag, uneven corners of the surrounding rock of the roadway, and high-frequency turns.Its power supply is a rubber-sheathed or silicone rubber flexible cable.The cable is arranged by the winder of the underground people carrier, and the cable is dragged by the winder. It always has friction and contact with the roadway, the ground of the quarry or the wall of the roadway, which makes the cable insulation easily damaged, causing leakage, which in turn causes the underground people carrier to carry electricity.Therefore, effective measures and methods must be taken to protect the cables to reduce or eliminate the problem of leakage of underground people and vehicles.

The measures and methods are as follows: one end of the power cable of the underground people carrier needs to be in a firm state to meet the operating conditions.If the fixed end of the cable falls off, the power switch distribution box will be dragged and moved, which will cause a safety accident in severe cases.When the cable is fixed, the cable should be clamped with an iron clamp welded by a chain (the cable placed in the clamp should be protected before installing the clamp) to prevent the cable from being damaged and leaking electricity.The iron bolt is inserted into the wall of the hole about 0.5m from the ground, and the other end of the cable clamp chain is fixed to the bolt to achieve reliable fixation.

At the same time, it is necessary to ensure that the cable clamp does not touch the cable connector and the damaged part of the cable to prevent leakage.It is not allowed to use wind and water pipes as fixed points, and cables are not allowed to be laid on wind and water pipes. It is forbidden for cable joints and damaged parts of the cables to come into contact with wind and water pipes to prevent leakage of electricity from the cables and electricity from the wind and water pipes, causing personal injury.Check the operation of the horizontal and vertical rollers of the underground truck reel at any time.Blockage of the idler wheel is not allowed.When the roller is worn to the limit, it should be replaced in time to prevent cable damage and leakage.The length of the cable stored in the reel of the underground people carrier is not allowed to exceed the length specified in its technical parameters.Check the operation of the receiver at any time. If the receiver is found to be abnormal, it should be adjusted to a better state immediately to avoid damage to the cable.
