Description

Technical Field

[0001] This utility model relates to the field of cable protection clamp technology, specifically to a mining cable protection clamp. Background Technology

[0002] In mining operations, electricity is crucial for powering core facilities such as mining equipment, ventilation systems, and lighting. Cables, as the carriers of power transmission, need to be laid long-term on tunnel walls, floors, or around equipment. Due to the unique mining environment, with its complex conditions including falling rocks, mechanical collisions, dust accumulation, ground vibration, and geological subsidence, cable clamps are necessary to secure and limit cables, preventing direct contact between the harsh external environment and the cables.

[0003] However, most cable clamps are rigid connections when securing cables. When the cable is suddenly tightened by external forces such as equipment dragging or sudden vibration, the clamp cannot absorb the impact tension, causing the cable to break due to instantaneous overload. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a mining cable protection clamp.

[0005] The technical solution adopted in this utility model is: a mining cable protection clamp, comprising: The cable protection clamp body is composed of a lower cable protection clamp housing, an upper cable protection clamp housing, and a cable protection clamp connecting seat. The upper cable protection clamp housing is installed through one end of the lower cable protection clamp housing, and the cable protection clamp connecting seat is installed through the other end of the lower cable protection clamp housing. The buffer unit installed inside the lower housing of the cable protection clamp and the cable protection clamp connecting seat is used to achieve the effect of buffer protection; The buffer unit includes a sliding shell, which is fixedly installed on the surface inside the lower housing of the cable protection clamp. Two springs are installed inside the sliding shell, and a slider is slidably installed inside the sliding shell. A roller is rotatably installed at the other end of the slider.

[0006] Furthermore, two rollers are rotatably installed inside the lower housing and the upper housing of the cable protection clamp. The two rollers are symmetrically arranged.

[0007] Furthermore, limit grooves are formed on both sides of the sliding shell, and limit blocks are welded and installed on both sides of the slider, with the limit blocks sliding on the surface of the limit grooves.

[0008] Furthermore, the slider is slidably connected to the sliding shell via a limiting block and a limiting groove.

[0009] Furthermore, the cable ports at both ends of the upper housing of the cable protection clamp are provided with multiple sliding grooves, and springs are installed inside the multiple sliding grooves. A spherical shell is slidably installed inside the sliding groove.

[0010] Furthermore, each of the multiple spherical shells has embedded balls installed inside. The cable passes through the cable port at one end of the cable protection clamp housing, sequentially through one of the rollers, roller 2 and roller 1, and then through roller 2 symmetrically from the other end.

[0011] Furthermore, one end of the second spring is welded to the surface of the groove, and the other end is welded to the lower surface of the spherical shell.

[0012] The above-described solution of this utility model has at least the following beneficial effects: In this invention, a buffer unit consisting of a sliding shell, a slider, a roller, and a spring is provided. When the cable is suddenly tightened by an external force, the force exerted by the cable on the roller will push the slider to slide inside the sliding shell and compress the spring. The elastic deformation of the spring absorbs the impact tension, preventing the cable from breaking due to excessive instantaneous force. After the external force disappears, the spring will automatically rebound and push the slider to reset, restoring the cable to a stable tensioned state and improving the cable's impact resistance and safety.

[0013] In this utility model, two rollers symmetrically arranged inside the protective clip allow the cable to roll instead of sliding during installation and use, reducing friction loss between the cable and the inner wall of the housing. At the same time, the spring at the cable opening and the spherical shell form an elastic clamping structure. The elastic thrust of the spring allows the spherical shell to always move closer to the cable, thereby allowing the balls inside the spherical shell to fit tightly against the cable surface.

[0016] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0017] like Figures 1 to 4 As shown, an embodiment of this utility model provides a mining cable protection clamp, comprising: The cable protection clamp body 1 is composed of a lower cable protection clamp housing 11, an upper cable protection clamp housing 12, and a cable protection clamp connecting seat 13. The upper cable protection clamp housing 12 is installed through one end of the lower cable protection clamp housing 11, and the cable protection clamp connecting seat 13 is installed through the other end of the lower cable protection clamp housing 11. The cable protection clamp connector 13 can fix the cable protection clamp body 1 to the ground or wall. The cable 3 can be supported by the upper housing 12 of the cable protection clamp and the cable protection clamp connector 13, thereby preventing long-term wear and damage on the mine wall or ground.

[0018] The buffer unit 2, which is installed inside the lower housing 11 of the cable protection clamp and the connecting seat 13 of the cable protection clamp, is used to achieve the effect of buffer protection. The buffer unit 2 includes a sliding shell 21, which is fixedly installed on the surface inside the lower housing 11 of the cable protection clamp. Two springs 24 are installed inside the sliding shell 21, and a slider 22 is slidably installed inside the sliding shell 21. A roller 23 is rotatably installed at the other end of the slider 22.

[0019] Cable 3 passes through the cable port at one end of the upper housing 12 of the cable protection clamp and is attached to a roller 27, then passes through and is attached to roller 23, and finally passes through and is attached to another symmetrical roller 27, and exits through the cable port at the other end of the upper housing 12 of the cable protection clamp. When the cable opening is suddenly tightened by external force, the cable 3 at point 23 of the roller is given an upward force, which causes the slider 22 to compress the spring 24 in the sliding shell 21, thus buffering the cable 3, preventing the cable 3 from breaking, and protecting the cable 3. After the external force disappears, the spring 24 rebounds and restores the slider 22 to its original state, keeping the cable 3 in a taut state.

[0020] like Figure 2 As shown, two rollers 27 are rotatably installed inside the lower housing 11 and the upper housing 12 of the cable protection clamp. There are two rollers 27 rotatably installed, and the two rollers 27 are symmetrically arranged.

[0021] Two symmetrical rollers 27 make the cable 3 slide more smoothly and prevent the cable 3 from wearing out.

[0022] like Figure 2 and Figure 3 As shown, limit grooves 26 are formed on both sides of the sliding shell 21, and limit blocks 25 are welded and installed on both sides of the slider 22. The limit blocks 25 slide in a limited manner on the surface of the limit grooves 26.

[0023] like Figure 3 As shown, the slider 22 is slidably connected to the sliding shell 21 through the limiting block 25 and the limiting groove 26.

[0024] The slider 22 is limited to slide against the sliding shell 21 by the limiting block 25 and the limiting groove 26, which can prevent the sliding shell 21 and the slider 22 from falling off during sliding.

[0025] like Figure 4 As shown, multiple grooves 211 are provided at both ends of the cable port of the upper housing 12 of the cable protection clamp. Springs 28 are installed inside the multiple grooves 211, and a ball shell 29 is slidably installed inside the grooves 211.

[0026] like Figure 4 As shown, multiple spherical shells 29 are each embedded with ball bearings 210. The cable 3 passes through a cable port at one end, then passes through a roller 27 and a roller 23 in sequence, and then symmetrically exits from the other end.

[0027] like Figure 4 As shown, one end of spring 28 is welded to the surface of the slide groove 211, and the other end is welded to the lower surface of the spherical shell 29.

[0028] When the cable 3 moves at the cable opening, the ball 210 can reduce the friction of the cable 3, and the groove 211 can make the ball 210 fit tightly against the cable 3, which has a clamping and stabilizing effect on the cable 3, while the ball shell 29 ensures the stability of the ball 210 rolling.

[0029] Working principle: Cable 3 first enters through the cable port at one end of the upper housing 12 of the cable protection clamp, and then sequentially comes into contact with one of the rollers 27 symmetrically arranged inside the lower housing 11 and the upper housing 12 of the cable protection clamp, and then with roller 23 in the buffer unit 2. Finally, after coming into contact with the other symmetrical roller 27, it exits through the cable port at the other end of the upper housing 12 of the cable protection clamp. When cable 3 is suddenly tightened by an external force, cable 3 will exert an upward force on roller 23, causing the slider 22, which is rotatably connected to roller 23, to slide and compress inside the sliding shell 21. The two springs 24 inside the shell 21 absorb external impact through their elastic deformation, preventing the cable 3 from breaking due to excessive instantaneous force. Simultaneously, the limiting blocks 25 on both sides of the slider 22 slide along the limiting grooves 26 on both sides of the shell 21, preventing the slider 22 from disengaging from the shell 21 and ensuring stability during the buffering process. When the external force disappears, the springs 24 rebound, pushing the slider 22 back to its original position, causing the roller 23 to return to its initial position, thus keeping the cable 3 taut again. Furthermore, the rotational characteristics of the roller 27 reduce friction during cable 3 movement, preventing surface wear. One end of the spring 28 installed inside the slide groove 211 is welded and fixed to the surface of the slide groove 211, and the other end is welded to the lower surface of the ball shell 29 slidably installed inside the slide groove 211. Under the elastic thrust of the spring 28, the ball shell 29 will always move closer to the cable 3, so that the ball 210 embedded inside the ball shell 29 fits tightly against the surface of the cable 3. When the cable 3 moves at the cable opening, the ball 210 rolls with the cable 3, which greatly reduces the frictional resistance between the cable 3 and the cable opening and further protects the outer surface of the cable 3. At the same time, the cooperation between the spring 28 and the ball shell 29 can form an adaptive clamping for cables 3 of different diameters, ensuring that the position of the cable 3 is stable in the cable opening and avoiding additional wear caused by the shaking of the cable 3. The ball shell 29 can limit the rolling trajectory of the ball 210, prevent the ball 210 from falling off, and ensure the long-term effective operation of the structure.

[0030] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
