Abstract
The utility model discloses a kind of cable of powering to mine down-hole, this cable comprises the cable and steel wire rope that be arranged in parallel, cable is provided with multiple clamp, steel wire rope is provided with multiple wire line shoe, is fixedly connected with between clamp and wire line shoe.A kind of cable of powering to mine down-hole of the present utility model can solve conventional art in the wellbore cabling time, cable is easily subject to the object fall such as ore, material and smashes and be subject to equipment in pit shaft and scratch and cause the problem of dead electricity, decrease the chance of the adverse circumstances such as conductive cable contacts humidity, dust, improve its useful life, equipment replacement simultaneously and maintenance process do not affect the production of auxiliary shaft, improve production efficiency.
Description
Technical field
The present invention relates to power cable, be specifically related to a kind of cable of powering to mine down-hole.
Background technology
Underground mine is when exploiting, and generally powered by the power consumption equipment of cabling to down-hole, meanwhile, the communication information, control signal etc. in mine also need to be transmitted mutually by cable.At present, mine is generally laid in auxiliary shaft to underground power supply used, transmission communication and control signal etc. cable, is fixed on the borehole wall, and lays downwards to down-hole central substation by the cable bearer be welded by shaped steel.This technical scheme has multiple drawback: be provided with the lifting means such as cage in (1) auxiliary shaft simultaneously, and for promoting mine car, ore, material and equipment, in lifting process, ore, material etc. fall to easily smashing cable, make down-hole dead electricity, and security incident occurs; (2) mine wellbore environment is severe, and cable bearer drenches and corrosion by water, and its intensity is lower and cable cannot be fixed along the borehole wall, causes cage, counterweight scratch cable, makes down-hole dead electricity, and security incident occurs; (3) in pit shaft, cable covering is easily aging by harsh environmental effects such as humidity, dust, can reduce the useful life of cable; (4) patrol officer needs often to patrol the cable laid in the wellbore, the cable bearer of corrosion and cable are changed, there is potential safety hazard in this process, simultaneously, mine auxiliary well production task is heavy, the process changing cable bearer and cable is complicated, and required time is long, affects the normal production of auxiliary shaft.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the utility model proposes a kind of cable of powering to mine down-hole, cable can be solved and be easily subject to the object fall such as ore, material and smash and be subject to equipment in pit shaft and scratch and cause the problem of dead electricity.
Above-mentioned purpose is realized by following proposal.
A kind of cable of powering to mine down-hole, it is characterized in that, this cable comprises the cable and steel wire rope that be arranged in parallel, and described cable is provided with multiple clamp, described steel wire rope is provided with multiple wire line shoe, is fixedly connected with between described clamp and described wire line shoe.
Cable of powering to mine down-hole according to claim 1, is characterized in that, a described clamp is fixedly connected with multiple described wire line shoe.
Cable of powering to mine down-hole according to claim 1, is characterized in that, multiple clamps that described cable is arranged are equidistant setting.
Cable of powering to mine down-hole according to claim 1, is characterized in that, described cable and steel wire rope overcoat have steel pipe.
A kind of cable of powering to mine down-hole of the present utility model can solve conventional art in the wellbore cabling time, cable is easily subject to the object fall such as ore, material and smashes and be subject to equipment in pit shaft and scratch and cause the problem of dead electricity, decrease the chance of the adverse circumstances such as conductive cable contacts humidity, dust, improve its useful life, equipment replacement simultaneously and maintenance process do not affect the production of auxiliary shaft, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
As shown in Figure 1, a kind of cable of powering to mine down-hole of the present utility model comprises cable 1 and steel wire rope 2.Cable 1 is provided with multiple clamp 3, steel wire rope 2 is provided with multiple wire line shoe 4, is fixedly connected with between clamp 3 and wire line shoe 4.Cable 1, steel wire rope 2, structure between clamp 3 and wire line shoe 4 can prevent cable dead weight excessive and rupture.
Especially, a clamp 3 can be fixedly connected with multiple wire line shoe 4, the equidistant setting on cable 1 of multiple clamp 3.
Cable 1 and steel wire rope 2 outer cover have steel pipe 5.
The installation process of power cable of the present utility model is as follows:
Select on earth's surface the good location of ROCK CONDITIONS to hole, after down well placement is got in boring, diameter is slightly less than down in boring after steel pipe 5 firm welding of bore diameter, and adopts oil-well cement 6 to carry out solid pipe, ensure that steel pipe 5 is fixing in the borehole.Then by multiple clamp 3 banding of cable 1, multiple wire line shoe 4 banding of steel wire rope 2, is fixedly connected with wire line shoe 4 with clamp 3 subsequently.Finally, transfer to steel pipe by the structure of the cable 1 of installation, steel wire rope 2, clamp 3 and wire line shoe 4, so far, cable successfully lays to down-hole.
