Abstract

This invention relates to a mine hoist and can be used to replace balancing cables in a mine hoist. The purpose of the invention is to reduce the labor intensity of replacing balancing cables in installations in which the weight of the replaced cables exceeds their carrying capacity. The method of replacing the ropes when using a lifting machine is to replace the balancing rope from the trunk to the pulley of the friction with a lifting machine and then twist it onto the mine’s industrial site, after which the hanging balancing rope from the mine’s platform is exhausted by the same lifting machine to the pulley of the shaft and lower it into the shaft shaft. Next, the ends of the hanging rope are attached to the vessels and proceed to the replacement of the head ropes 7 or

Description

The invention relates to a mine hoist, in particular to methods for replacing ropes of a multi-rope hoisting installation, and can be used in the coal, mining and color industries.

The purpose of the invention is to replace ropes separately and reduce the complexity of replacing balancing ropes in installations in which the weight of the ropes being replaced exceeds their carrying capacity.

FIG. 1 shows a diagram of a lifting installation with a mounting rope attached to the friction pulley when replacing balancing cables; in fig. 2 is a diagram of a lifting device with a replaceable balancing cable attached to the installation rope for issuing it from the barrel to the friction pulley; in fig. 3 is a diagram of a lifting installation when issuing a replacement equilibrium rope to a friction pulley and from the latter to the mine site; in fig. 4 is a diagram of a lifting installation with a hanging balance cable attached to the installation rope for issuing it from the mine site to the friction pulley: FIG. 5 is a diagram of a lifting device when lowering a balancing rope from a friction pulley into the shaft of a shaft; in fig. 6 is a diagram of a lifting installation with a hanging balance cable attached to the shaft shaft connected to the mounting rope. in fig. 7 is a diagram of a lifting installation with a suspended balance cable attached to the lifting vessels. When replacing ropes, a multi-gang lift installation contains a drive pulley 1 of a lifting machine, from which replaceable head ropes are removed, attached to the friction pulley 1 for a period of replacement of balancing ropes mounting cable 2. lifting vessels 3 and 4. installed receiving platforms on the overlap of the trunk and copra, or hung on the slings to the metal trunk and copra, balancing rope 5, to be noticed. diverting rollers 6 and 7 installed in

a building building for the period of ropes replacement, a hanging balancing cable 8 located on the mine site, connecting clamps 9 for attaching a replaceable rope 5 (Fig 2) or a hanging rope 8 (Fig 4 and Fig 6) to the mounting rope 2, and holding clamps 10 on the weight of the cable to be replaced 5 (FIG. 1 and FIG. 2) or on the hanging cable 8 (FIG. 6), the landing bridge 11, on which the clamps 10 rest. In the first case, the clamps 10 are used when disconnecting the cable to be replaced 5 from vessels 3 and 4 (FIG. I and FIG. 2), in the second case, when attaching, we hang 8th rope to vessels 3 and 4 (Fig. 6)

The method is carried out as follows.

To remove the replacement equilibrium cable 5, the cable 5 fastens the clips 10, which rest on the landing bridge 11 (Fig. 1). Then the cable 5 is disconnected from the vessels 3 and 4 and the upper end of the cable 5 is attached to the installation cable 2 by means of connecting clips. 9 (FIG. 2) Next, rotating the friction drive pulley 1 with a lifting machine, lift the replaceable rope 5 together with the clips 10 from the landing bridge 11, check the reliability of fixing the ropes 2 and 5 in the connecting clamps and remove the clips 10 Continuing to rotate the friction drive pulley 1 issued on a replaceable balancing cable 5 together with connecting clips 9 (FIG. 2 and FIG. 3) are replaced from the shaft of the shaft; then, rotating the drive pulley 1 in the opposite direction, a replaceable balancing cable 5 is delivered to the mine’s production site (FIG. 3). of the clamps 9 to the receiving site, that is, in the lower part shown in FIG. 2, FIG. 4 and FIG. 6, the replaceable rope 5 is disconnected from the installation rope 2 and a suspended balance rail 8 is attached to the rope 2 attached to the mine industrial site (FIG. 4) Then the rope 8 is issued lifting driving machine

friction pulley 1 (FIG. 5), after which, rotating it in the opposite direction, the rope 8 is lowered into the shaft shaft (FIG. 6) On the landing bridge II, clamps 10 are installed on the rope 8 (FIG. 6) and the ropes 2 and 8 are connected connecting clamps 9 Then the ends of the rope 8 are connected to vessels 3 and 4 (Fig. 7) and clamps 10 are removed, holding the rope 8 on the landing bridge 11. This completes the process of replacing the balancing cables 5 and 8

Then, the landing axle 11 is lifted, the discharge rollers 6 and 7 and the mounting rope 2 are removed from the friction pulley 1 and proceed to winding on the friction pulley 1 or the hanging ropes
