Figure 3 for Figure 1 The diagram shows the structure of the through-hole and the fixing bolt.

[0024] Figure 4 for Figure 1 The diagram shows the structure of the clamping plate and the primer layer. The rope clamping device for the mine hoist includes two clamping plates 1 that are arranged opposite each other and clamped together. The opposite surfaces of the two clamping plates 1 are provided with connecting grooves 2. The two connecting grooves 2 form a cylindrical groove. The inside of the cylindrical groove is provided with an anti-slip structure for clamping the rope. The two clamping plates 1 are connected and detached by several bolt groups 8.

[0025] One end of the card plate 1 is fixedly connected to a positioning strip 9, and the other end of the card plate 1 is provided with a positioning groove 10 that is adapted to the positioning strip 9.

[0026] A horizontal plate 11 is fixedly connected to the top and bottom of one end face of the card plate 1. An opening 12 is provided on the horizontal plate 11. A connecting seat 13 adapted to the horizontal plate 11 is fixedly connected to the upper and lower parts of the other end face of the card plate 1. A threaded hole 14 adapted to the opening 12 is provided on the outer side of the connecting seat 13.

[0027] After the connecting groove 2 is fitted onto the surface of the wire rope, the two clamping plates 1 are locked together to restrict and protect a single wire rope. Then, by embedding the positioning strip 9 into the positioning groove 10 on different clamping plates 1, multiple clamping plates 1 can be connected and positioned.

[0028] After positioning, the opening 12 moves to the corresponding position of the connecting seat 13. Then, the bolts pass through the inside of the opening 12 and are threadedly connected to the connecting seat 13. This fixes the adjacent horizontal plates 11 to the connecting seat 13, and then the two adjacent clamping plates 1 are combined in a modular manner. Depending on the working conditions, the corresponding number of clamping plates 1 can be combined, which can accommodate different numbers of wire ropes for protection, thus facilitating the operation of the mine hoist.

[0029] The anti-slip structure includes two arc-shaped plates 3, which are respectively detached and installed on the inner wall of one connecting groove 2 and the inner wall of the other connecting groove 2. Several anti-slip strips 7 are fixedly connected to the inner wall of the arc-shaped plates 3.

[0030] The upper and lower parts of the outer surface of the arc plate 3 are fixedly connected with fixing bolts 5. The surface of the clamping plate 1 is provided with a through hole 4 that is compatible with the fixing bolt 5. The other end of the fixing bolt 5 passes through the interior of the corresponding through hole 4 and is threaded with a nut 6.

[0031] When the clamping plate 1 is engaged, the anti-slip strip 7 comes into contact with the surface of the wire rope, improving the anti-slip properties and thus enhancing the stability of the clamping between the device and the wire rope. After opening the clamping plate 1, the nut 6 can be twisted to remove the arc plate 3, making it easy to replace the anti-slip strip 7.

[0032] The outer surface of the card plate 1 is coated with a primer layer 15, which covers the surface of the card plate 1. The outer surface of the primer layer 15 is coated with an anti-corrosion coating 16. A reinforcing rib is fixedly connected between the inner end of the horizontal plate 11 and the side wall of the card plate 1.

[0033] The working principle of the rope clamping device for mine hoists provided by this utility model is as follows:

[0034] After the connecting groove 2 is fitted onto the surface of the wire rope, the two clamping plates 1 engage and fix each other, thus restricting and protecting a single wire rope. Then, by embedding the positioning strip 9 into the positioning groove 10 on different clamping plates 1, multiple clamping plates 1 can be connected and positioned. After positioning, the opening 12 moves to the corresponding position of the connecting seat 13, and then the bolt passes through the inside of the opening 12 and is threadedly connected to the connecting seat 13, thus fixing the adjacent horizontal plate 11 to the connecting seat 13, and then combining the two adjacent clamping plates 1. When the clamping plates 1 are engaged, the anti-slip strip 7 contacts the surface of the wire rope, improving the anti-slip properties, thereby improving the stability of the clamping between the device and the wire rope.

[0035] Compared with related technologies, the rope clamping device for mine hoists provided by this utility model has the following advantages:

After positioning, the opening 12 moves to the corresponding position of the connecting seat 13. Then, by threading the bolt through the inside of the opening 12 to the connecting seat 13, the adjacent horizontal plates 11 are fixed to the connecting seat 13. The two adjacent clamping plates 1 can then be combined in a modular manner. The number of clamping plates 1 can be combined according to the working conditions, thus adapting to different numbers of wire ropes for protection, which is beneficial to the operation of mine hoists.
