Description

Technical Field

[0001] The invention patent relates to the field of coal mine equipment, in particular to a small material recovery device for anchor cables used in coal mines. Background Art

[0002] my country's coal mines are mainly mined underground, and a large number of tunnels need to be excavated underground. The use of tunnel support to keep the tunnels unobstructed and the surrounding rock stable is of great significance to coal mine construction and production. The basic purpose of tunnel support is to ease and reduce the movement of surrounding rock, so that the tunnel section will not be excessively reduced, and at the same time prevent the scattered and damaged surrounding rock from falling. At present, with the promotion of science and technology in the coal industry, anchor support technology has also been fully promoted, but with the increase of mine service life, the requirements for tunnel repair will gradually increase. A large amount of anchor support materials can usually continue to be used for support of other tunnels after the tunnel is used up. However, due to the difficulty of recycling mine anchor support materials, they are rarely effectively recycled, resulting in a large amount of waste of idle anchor support materials. In addition, even if there are a small amount of equipment that can be recycled, its structure is relatively complex, the cost is high, and the recycling effect is poor, which greatly hinders the recycling and reuse of anchor support materials.

DETAILED DESCRIPTION

[0013] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in combination with the accompanying drawings.

[0014] like Figure 1-2As shown in the figure, a coal mine anchor cable small material recovery device comprises a directional top pressure component 1, a pressure device 2 is arranged outside the rear end of the directional top pressure component 1, a support assembly 3 is arranged at the front end of the directional top pressure component 1, the support assembly 3 comprises a steel mesh 4 abutting against the coal wall of the roadway, the front end of an anchor cable 5 passes through the steel mesh 4 and is inserted into the coal wall of the roadway, an anchor cable leather plate 6 is tightly sleeved on the outer side wall of the anchor cable 5 on the rear side of the steel mesh 4, and an anchor cable iron plate 7 is tightly sleeved on the outer side wall of the anchor cable 5 on the rear side of the anchor cable leather plate 6 An anchor ball 8 is sleeved on the outer side wall of the anchor cable 5 on the rear side of the anchor cable iron plate 7, the steel mesh 4, the anchor cable leather plate 6, the anchor cable iron plate 7, and the anchor cable ball 8 are pressed against each other in sequence, and an inner ball core 9 is inserted in the cavity of the anchor cable ball 8. The inner cavity of the inner ball core 9 is tightly sleeved on the outside of the anchor cable 5, and the outer side wall is in contact with the cavity of the anchor cable ball 8. The directional pressing component 1 includes a set of hollow rigging 10 arranged on the outer side wall of the rear end of the anchor cable 5 on the rear side of the anchor cable ball 8, and the front end face of the hollow rigging 10 is in contact with the rear end face of the anchor cable ball 8.

[0015] The directional pressing component 1 also includes a connecting rod 11 fixedly connected to the outer side wall of the hollow rigging 10, and a handle 12 is fixedly connected to the distal free end of the connecting rod 11. When the hollow rigging 10 is installed by holding the handle 12, the convenience of installation and the stability after installation of the hollow rigging 10 can be ensured, and disassembly is also convenient.

[0016] The cavity of the hollow rigging 10 is in the shape of a horizontally placed truncated cone, and the inner diameter of the cavity of the hollow rigging 10 decreases from front to back. The distance from the front end face of the inner ball core 9 to the rear end face of the anchor cable 5 is less than the length of the hollow rigging 10, and the inner diameter of the cavity of the hollow rigging 10 is greater than the outer diameter of the inner ball core 9. When the hydraulic cylinder 15 is used to push the hollow rigging 10 to move forward, it can be ensured that only or mainly the anchor ball 8 is pushed forward, and finally a displacement difference is formed between the anchor ball 8 and the inner ball core 9, thereby ensuring that the inner ball core 9 is separated. When the outer periphery of the inner ball core 9 is separated from the tightening restriction of the anchor ball 8, the tightness between it and the anchor cable 5 will be greatly reduced. At this time, after the hollow rigging 10 is withdrawn outward, it will be easy to dismantle the steel mesh 4, the anchor cable leather plate 6, the anchor cable iron plate 7, the anchor cable ball 8 and other cuttings for recycling and collection.

[0017] The pressurizing device 2 includes a pulling jack 13 , and a hydraulic cylinder 15 is connected to the front end of the pulling jack 13 through a connecting oil pipe 14 . The piston rod at the front end of the hydraulic cylinder 15 cooperates with the rear end surface of the hollow rigging 10 .

[0018] A pressure gauge 16 for detecting the internal pressure of the hydraulic cylinder 15 is provided on the cylinder body of the hydraulic cylinder 15 , so that the current pressure status of the hydraulic cylinder 15 can be conveniently observed, thereby facilitating the constant pressure hollow rigging 10 .

[0019] Working principle:

[0020] When in use, the directional pressing component 1 can be sleeved on the end of the anchor cable 5 at the rear end of the support assembly 3 by grasping the handle 12. After placement, the operator can hold the handle 12 to enhance the stability of the entire directional pressing component 1, and then control the pressure device 2 to apply pressure to the directional pressing component 1, and use the hydraulic cylinder 15 to push the hollow rigging 10 to move forward, thereby pushing the anchor ball 8 forward, and finally forming a displacement difference between the anchor ball 8 and the inner ball core 9, thereby ensuring that the inner ball core 9 is separated. When the outer periphery of the inner ball core 9 is free from the fastening restriction of the anchor ball 8, the fastening between it and the anchor cable 5 will be greatly reduced. At this time, when the hollow rigging 10 is withdrawn outward, it will be easy to disassemble the steel mesh 4, anchor leather plate 6, anchor iron plate 7, anchor ball 8 and other materials for recycling and collection. The device is easy and convenient to operate, and reduces the difficulty of recycling.
