Problems solved by technology

Although the rapid construction technology of shaft shaft equipment below 1,000 meters is relatively advanced in China, there is obviously insufficient experience in the construction of shaft shaft equipment for shafts with a length of 1,500 meters.

Embodiment Construction

[0026] The anti-rotation installation method of heavy weight head and tail ropes in ultra-deep shafts is characterized in that the process steps are as follows: ① Divide the head ropes into n groups of two from the outside to the inside; Manufacture of rotating device, ③Arrange two hydraulic brake sinking winches on the ground, ④Use two hydraulic brake sinking winches and 2 old steel wire ropes to lower the lifting container Ⅰ to the bottom of the well, ⑤Use hydraulic brake to sink the well The drawworks, the sky pulley on the top wheel platform of the permanent derrick, each group of head rope anti-rotation devices and tail rope anti-rotation devices respectively lower each group of head ropes and tail ropes to the bottom of the well, and each group of head ropes that go down to the bottom of the well The lifting container I and the lifting container II are fixedly connected with the tail rope respectively.

[0027] The number of first ropes is six, which are divided into 3 g...

Abstract

The anti-rotation installation method of extra-deep vertical shaft of fore and aft rope comprises the processing steps that:(1)each two pieces of fore rope is integrated into one group from outside toinside, and there are n groups; (2) preparing anti-rotation devices of each fore rope group and anti-rotation devices of each aft rope group; (3) installing two hydraulic braking sinking winches on the ground; (4) by using the two hydraulic braking sinking winches and two old steel wires, a lifting container I is lowered to the bottom of the well; (5) using the hydraulic braking shaft winches, ahead sheave of a permanent derrick sheave wheel platform, the anti-rotation devices of each fore rope group and each aft rope group, each fore rope and each aft rope are bellowed to the shaft bottom,and the fore rope and the aft rope are respectively and fixedly connected with the lifting container I and a lifting container II. Compared with the prior art, the anti-rotation method and devices have the following advantages: 1. the installing quality and the processing precision are improved; 2. the over rotation of the fore and aft ropes is prevented and then the construction safety is improved; 3. the construction efficiency is improved; 4. the devices are simple in structure, convenient in processing steps, light in weight and easy in execution.

Description

technical field [0001] The invention relates to a method for installing head and tail ropes of a vertical shaft, in particular to an anti-rotation installation method and an anti-rotation device for installing heavy-weight head and tail ropes of an ultra-deep shaft. Background technique [0002] At present, my country's metal mines are gradually facing the situation that shallow minerals are gradually depleted. Many mines have been mined to a critical depth, and it is urgent to develop deep deposits. With the continuous deepening, mines exceeding one thousand meters have appeared one after another, and some shafts are even deeper than 1500m. Although the rapid construction technology for shaft shaft equipment below 1,000 meters is relatively advanced in China, there is obviously insufficient experience in the construction of shaft shaft equipment for shafts with a length of 1,500 meters. As we all know, the installation of shaft permanent lifting facilities includes the plac...
