TECHNICAL FIELD

[0001] The utility model relates to cable protection technical field, concretely is coal mining equipment cable protection equipment for coal mining. BACKGROUND

[0002] Coal mining is to separate and transport valuable coal from underground or surface. Coal deposits are layered, widely distributed, large in reserves, brittle and easy to cut and break, and often accompanied by water, fire, gas and other disaster threats during mining. Compared with the mining of other minerals, coal mining technology has some different characteristics. Mining methods are divided into open-pit mining and underground mining. Usually, mechanical methods are used; a few use hydraulic coal mining; underground coal gasification is still in the experimental stage. Mechanical methods are used for coal mining, and mining equipment is deep into the mine, and then connected to the external power supply for driving. The cable used in the mine often bends with the movement of the coal mining equipment. When the cable is excessively bent, it can cause excessive stress inside the cable, thereby accelerating the aging of the cable, and the damage to the conductor, the insulating layer and the sheath is intensified. During the use of the coal mining equipment, there is no protection for the cable, so the risk of core breakage is easy to occur, which affects the normal use of the coal mining equipment. SUMMARY

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5The utility model discloses a kind of cable protection equipment for coal mining equipment for coal mining, comprising: bending degree adjusting mechanism 100, protection mechanism 200, bending degree adjusting mechanism 100 can lock the bending degree of cable to avoid excessive bending, bending degree adjusting mechanism 100 includes two support seats 101, one support seat 101 side wall is fixedly connected with arc slide rail 104, arc slide rail 104 is slidably sleeved with arc slide strip 105, limit groove 106 is formed in the top of arc slide strip 105, arc slide strip 105 end is fixedly connected with positioning block 108, arc slide rail 104 top is fixedly connected with top shell 109, multiple round holes 110 are equidistantly formed on top shell 109, round hole 110 is inserted with locking column 111 that is screw connection with positioning block 108, when cable is bent to suitable angle, locking column 111 is inserted into the round hole 110 in top shell 109 and is screw connection with positioning block 108, so that arc slide strip 105 and arc slide rail 104 no longer relatively slide, and the position of the two support seats 101 is fixed, protection mechanism 200 can be insulated and buffer protected to the outside of cable.

[0026] Specifically, by setting cable protection equipment at the turning of cable, after connecting cable through flexible sleeve 205 and coal mining equipment, rotating turnover shell 202 and bottom shell 201 are combined to protect the outside of cable, and two fixed blocks 206 on one side of turnover shell 202 and corresponding clamping seat 207 are embedded, insert rod 209 is moved by driving plate 208, when fixed block 206 slides into clamping seat 207, release, insert rod 209 is locked to fixed block 206 under the action of reset spring 210, so that cable protection equipment is conveniently disassembled and installed.

[0027] Adjusting the included angle between the two support seats 101 will cause the arc-shaped slider 105 and the arc-shaped slide rail 104 to slide relative to each other. The support seats 101 are rotatably connected by the rotating column 102. When the position of the support seat 101 changes, the position of the bottom shell 201 and the flip shell 202 will also be adjusted. When the cable is bent to a suitable angle, the locking column 111 is inserted into the round hole 110 in the top shell 109 and screwed into the positioning block 108. In this way, the arc-shaped slider 105 and the arc-shaped slide rail 104 will no longer slide relative to each other. Similarly, the position between the two support seats 101 is fixed, so the degree of bending of the cable is fixed. This can protect the cable from excessive bending when used in the mine, which would shorten the service life of the cable.

[0028] Example 1

[0029] like Figure 5 As shown, in this embodiment, the protective mechanism 200 includes two bottom shells 201 fixedly connected to the top of the support base 101. A flip shell 202 is rotatably connected to each of the two bottom shells 201. A socket joint 203 is fixedly connected to both ends of the bottom shells 201 and the flip shell 202. A flexible sleeve 205 is located between the two bottom shells 201. A sealing ring 204 is fixedly installed on the inner wall of the socket joint 203. An elastic buffer layer 213 is fixedly installed on the inner wall of both the bottom shells 201 and the flip shell 202. A flame-retardant cotton layer 212 is fixedly installed on the inner wall of the elastic buffer layer 213. An insulating layer 211 is fixedly installed on the flame-retardant cotton layer 212. With the insulating layer 211, the flame-retardant cotton layer 212, and the elastic buffer layer 213 located between the bottom shells 201 and the flip shell 202, the flame-retardant cotton layer 212 provides a certain flame-retardant effect for the cable, while the elastic buffer layer 213 provides a cushioning effect when a heavy object falls on the cable.

[0030] In specific implementation, an insulating layer 211, a flame-retardant cotton layer 212, and an elastic buffer layer 213 are provided between the bottom shell 201 and the flip shell 202. The flame-retardant cotton layer 212 can play a certain flame-retardant role for the cable, while the elastic buffer layer 213 plays a buffering role when a heavy object falls on the cable. Therefore, the protective mechanism 200 can play a good protective role for the cable, prevent the cable from breaking during use, and ensure the normal operation of the coal mining equipment.
