(54) DEVICE FOR SUPPLYING ENERGY TO THE MINING MACHINE IN THE DEVELOPMENT

one

The invention relates to the laying of energy mains between mutually moving objects and can be used in mining when sinking mines to supply energy to the mining machine in the bottom zone .5

The known supporting system of the movable cable, containing a horizontal direction, on which the carriages are mounted on the rollers, carries the cable loops, the end of which is embedded on the vehicle Q.

A disadvantage of the known device is the need for large labor costs when moving the entire system to another work zone, due to dismantling the carriages and guides, transporting them and then installing them in a new system work zone.

The closest to the present invention is a device for supplying energy to a mining machine in a mine, containing Q grips mounted on the mine workpieces, a cable tensioned between the jaws parallel to the longitudinal axis of the mine, and suspensions made at one end in the form of an earring with an open circuit covering the cable with the possibility of movement, and connected at the other end with a flexible energy route 2.

The disadvantage of this device is the large labor costs for moving the energy trunk along with its suspension in the process of advancing the mine workings, due to the need to release the cable from the earrings, dismantle the cable, carry the grips, hang the cable to the new place and then tension it and hang the earrings. Removing, transferring and tensioning the cable without removing the earrings is difficult, since the weight of the cable or pneumatic manual together with the suspensions is very significant, and the cable is attached at a height of 2.5-3.0 meters from the working soil.

The purpose of the invention is to reduce labor costs during operation.

The goal is achieved by the fact that the device for supplying energy to the mining machinery in the mine, containing grips, designed to be mounted on the lining of the mine workings, a cable tensioned between the grips parallel to the longitudinal axis of the mine and suspension, one end fixed in the form of earrings covering the cable with the ability to move along it, is equipped with an additional cable and clamps, on which an additional one is mounted with an offset in the longitudinal direction relative to the main cable Yelnia rope schag offset which is equal to the advance of generation per cycle, each of the hangers mounted to cover both cables, the suspension formed to the extreme end of the second closed loop.

Such an implementation allows to reduce labor costs by excluding operations to free the cable from earrings, transport the energy trunk line through the soil of the mine with its subsequent rise to a fixed level and visit the earrings.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

A device for supplying energy to the mining machine in the mine contains the main cable 1, the auxiliary cable 2, tensioned on the grippers 3. The grippers 3 are mounted on the support 4 of the mine working. Cable 2 is offset from cable 1 by the amount of advancement of the mine workings per cycle.

The energy route 5 is flexible, connected to the machine, fixed in cages 6 hangers 7, the second end of which, made in the form of earrings 8, simultaneously covers both cables. Earrings of extreme hangers are made with a closed loop, because otherwise they will not move fixed at the height of the suspension, which subsequently will lead to the need to lift it to the specified height.

The suspensions are fixed on the energy line with a certain pin, the minimum size of which is determined by the allowable bend radius of the energy line, and the maximum - by excluding the possibility of the lower part of the loop of elements of the mining equipment touching the full alignment of adjacent suspensions

 (Hh),

where E is the pitch of the suspension;

H - the height of the suspension cable relative

soil;

h is the maximum height of mining equipment in the mine. The device works as follows. When the mining machine is moving, the energy route connected to the machine moves the suspensions along the mine to the face.

The main cable 1 is ice for the movement of the mining machine.

At the end of the mining cycle, the main cable 1 is disconnected from the grips 3, which are transferred in the downstream direction by an amount equal to the double advancement of the excavation per cycle, then, after fixing the grips on the support, the main cable 1, In the next cycle, it acts as an auxiliary cable, the auxiliary cable being the main cable at that time.

A smooth transition from the main cable to the auxiliary cable without any additional labor costs is also ensured by the fact that each of the earrings is installed with the possibility of simultaneously covering both cables.

When moving the machine from the bottom in accordance with the technology of mining, there is a gradual convergence of the suspensions with the formation of energy-hinge loops. In the extreme position of the mining machine, there is a complete convergence of adjacent suspensions up to their direct contact.
