Anti-intertwisting installation method of putting shaft cable downward through two winches

Abstract

In vertical shaft equipment of coal mines and non-coal mines, when a winch (1) is used for putting a cable downward, a wire rope (4) of the winch and the cable (9) are liable to intertwist with each other, and a great technical difficulty is brought to the construction of the cable (9). The scheme provides an anti-intertwisting installation method of putting the shaft cable (9) downward through two winches (1, 2). When the cable (9) and the wire rope (4) intertwist with each other, a wire rope (5) of the other winch (2) is connected to an appropriate position under the position where the cable (9) and the wire rope (4) intertwist with each other, and is tightly connected with the wire rope (4) for putting the cable (9) downward, and replaces the original wire rope (4) which puts the cable (9) downward to bear the force. After the wire rope (5) is confirmed to bear the force, the original wire rope (4) which puts the cable (9) downward is gradually loosened, and the wire rope (4) and the cable (9) are naturally separated. The cycle repeats until the installation of the cable (9) is finished.

Description

1. Technical field: [0001] In the shaft shaft equipment of coal mines and non-coal mines, various process cables such as power cables and communication cables connecting the ground and underground are fixed on the cable brackets in the shaft shaft (see figure 1 ). 2. Background technology: [0002] When the construction unit installs shaft cables, especially large-diameter power cables, most of them use stable vehicles to lower them. Even small communication cables can only be lowered by stable vehicles as long as they are arranged at the opening of the beam. The main method steps as follows: [0003] 1. Arrange a stabilizing car on the ground and root it firmly. The direction of stabilizing the car is aligned with the direction of the lowering point (see figure 2 ). [0004] 2. Arrange the cable reel waiting to be lowered at an appropriate position at the wellhead, and arrange a large-diameter empty rope roll at the position where the cable is lowered at the wellhead, s...

[0013] (5) When dealing with this kind of twisting force, the operator always adopts the most primitive method, directly inserts the crowbar into the twisting position, rotates the twisting force in the opposite direction, and forcibly separates the steel wire rope from the cable, so that the cable can be fixed to the permanent cable On the bracket, this stupid method is time-consuming, extremely unsafe, and damages the protective layer of the permanent cable

[0014] (6) Especially when the twisting force is large and there are many twisting forces, the operator can't find a better way underground. For one twisting force, one shift can't handle it for a few days. Finally, a large-scale cutting of small ties is used , forcibly tearing cables and wire ropes with chain hoists, the method is clumsy and extremely dangerous
