Description

A kind of shuttle car for coal mine metal-shielded rubber-sheathed flexible cable

Art

The utility model belongs to Coal Mine Power Distribution System emergency electric supply unit technical field, specifically a kind of shuttle car for coal mine metal-shielded rubber-sheathed flexible cable.

Background technology

Coal rubber sheathed flexible cable for mine is the indispensable auxiliary products of coal industry, along with the continuous progress of mining technique, the Coal Electricity cable demand with special purpose and high performance index increases sharply, shuttle car for coal mine metal-shielded rubber-sheathed flexible cable is exactly one of them, and it is as the connecting line of electric power and Signal transmissions.Shuttle car refers to the transport vehicle being transported coal by coal work towards transport tape, because it moves back and forth between coal-face and conveyer belt, as the shuttle on weaving loom, therefore is called shuttle car.Shuttle car for coal mine metal-shielded rubber-sheathed flexible cable is the connecting line for shuttle car transmission power and signal, and its one end connects shuttle car equipment, and one end connects power supply and control appliance.In use along with the motion of shuttle car, be in all the time be wound-stretching-reel again-stretching again cycle movement state under.The very narrow and hard objects such as residing visible gangue in tunnel in the tunnel of underground coal mine, cable have at any time by the borehole wall, supporting thing and gangue etc. hang wound, scratch may; Be subject to the restriction of cable hoist self-capacity and shuttle car range ability in addition, the outside dimension of cable also must have strict restriction.Because environment for use is severe and the restriction of service condition, the useful life of coal mine shuttle car cable is very of short duration.Tens of sky that often comes into operation even just there will be open circuit or short trouble several weeks, causes shuttle car to stop work, thus directly impact is mined and normally the carrying out of driving.The fault that coal mine shuttle car cable frequency of occurrence is maximum is exactly disconnected core, and substantially cannot spot repair when disconnected core fault appears in cable.Common way changes cable exactly, is all removed by cable, then new cable is transported to underground site be wound up on cable hoist from cable hoist.It is important to note that the replacing of above-mentioned cable is operated in that underground coal mine is narrow, in the tunnel of bad environments, almost completely by manually having come, unavoidably adding the labour intensity of coal miner, adding production cost, reducing production efficiency.In recent years, more domestic cable manufacturers have carried out some according to user's service condition to the construction of cable in the past used and have improved, but the performance of cable is difficult to meet instructions for use all the time.
