Abstract

COLLECTOR FLEXIBLE LINE winning machine, comprising a stationary carriage angularly block movable blocks for mains supply and wetting compensator-rocker, characterized in that in order to provide a joint sampling mains supply and wetting compensator-balancer is movable and is located on suspension mechanism, and on the one hand it is connected to the drive, and on the other by means of cables - with two moving blocks.

Description

The invention relates to the coal industry and is intended for mechanized sampling (descent), as well as laying on the ventilation drift two highways (energy supply and irrigation) of the excavation machine, working on the steep slope, their formations.

The aim of the invention is to provide jointly sampling of power supply and irrigation lines.

The drawing shows a schematic diagram of the pick-up.

Suspension mechanism 1 is fastened to the metalwork fasteners of the ventilation drift. A fixed carriage 2 is mounted on the suspension device, on which the corner unit 3 is mounted. The carriage stops at the metalworking arches with the HANDLE 4 of the core fixing its position relative to the mouth of the lava during operation . Similarly, the locking is the drive 5. The drive cable 6 is connected to the balance compensator 7, which is a block of pulleys 8 and 9 of different diameters that are rigidly connected to each other and installed on the common axis 10 of the trolley 11. The pulley 8 of smaller diameter is in turn connected by a cable 12 with the movable unit 13 of the power supply line 14 (air line or electric cable), and 1kiv 9 of larger diameter - with the cable 15 with the movable unit 16 of the irrigation highway 17.

Power supply lines and irrigation lines 14 and 17 are fixed at one end to connectors 18 and 19 on a stationary carriage 2, to which respective district lines are connected, bend around moving blocks 13 and 16, corner unit 3 and the other end are connected to combine 20.

The supporting devices 21 are designed to keep the lines 14 and 17 from sagging.

Picker works as follows.

When the combine is moving from the bottom up, the pick-up drive 5 automatically turns on. Under the action of the drive force of the drive, the moving blocks 13 and 16 move together with the balancer-balancer 7 along the suspension mechanism 1 towards the drive.

Moving along, the blocks select the movable branches of the lava highways and place them along the gateway on supporting devices 21. The working length of the lines is laid on the drift section, approximately equal to half the bottom length.

As the combine moves from top to bottom, the pickup drive automatically shuts down. Under the action of the weight of the combine, the lines 14 and 17 are carried along into the lava, all moving elements of the pick-up move in the opposite direction, and the rope is unwound from the drive drum. As a consequence, the motor-pump in the drive hydraulic system starts to operate in pump mode. By throttling the working fluid being pumped, the moving blocks are braked, thereby avoiding the possibility of care

0 in the lava of highways under the action of its own weight.

The redistribution of the tension forces between the movable blocks of the lines, as well as the compensation of the various stretches of the lines 5, is carried out by a balance compensator.
