Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a support for power transmission cables in mines. Background Technology

[0002] In mining operations, the stability of power supply is crucial, and the support and fixation of power transmission cables are key to ensuring normal power transmission. However, the unique characteristics of the mining environment present numerous challenges to the performance and function of cable supports.

[0003] Existing Chinese patent CN222593066U discloses a mine power transmission cable support, including a support body and a drive assembly. The drive assembly and the support body are limited by a limiting protection component. The drive assembly includes a rotating motor, a winding roller, and a cable clamping assembly. The winding roller includes a limiting clip. The cable clamping assembly includes a mounting frame, a support rod, a turntable, and a limiting clip. The support rod has a fixed limiting clip, and the turntable has a movable limiting protrusion. The limiting protection component includes an auxiliary spring and fixed hooks at both ends of the auxiliary spring. This utility model belongs to the field of cable laying technology and specifically solves the problems of existing cable supports lacking traction function, increasing laying difficulty, having huge traction equipment, being easily affected by terrain, and having limited use. It is a new type of mine power transmission cable support.

[0004] The walls of mine tunnels are often uneven, with various protrusions, depressions, and irregular shapes, making it difficult to securely install traditional cable supports. Many traditional supports use simple flat-fit or single-point fixing to connect to the wall, which are prone to loosening, displacement, or even detachment under frequent vibrations and external forces in mines. Once the support is unstable, the cable will lose support, potentially leading to cable pulling and abrasion, resulting in power transmission interruptions, affecting normal mine production, and even causing safety accidents. Furthermore, the power cables used in mines are diverse in specifications, diameter, and weight. Existing cable support clamping methods are relatively simple, usually only suitable for specific cable specifications, lacking flexibility and versatility. For cables of different diameters, different models of supports may need to be used, which not only increases costs but also affects construction efficiency. Utility Model Content

[0013] 1. In this utility model, the inclined rod is threadedly connected to the inclined threaded cylinder and embedded in the inclined hole of the support body, forming a stable triangular support frame together with the support body and the mine wall. Utilizing the principle of stability of a triangle, this greatly enhances the fixing strength of the support to the wall. Regardless of whether the mine wall surface is flat or not, this fixing method ensures that the support body fits tightly against the wall and remains stable. Even under strong vibration or large external force, the support is not prone to displacement or loosening, providing a reliable foundation support for the power transmission cable, effectively avoiding cable failures caused by unstable support fixing, and ensuring the stability of power transmission in the mine. 2. In this invention, the distance between the clamping plate and the base is adjusted by rotating the threaded rod. The spring can adaptively adjust according to the diameter and shape of the cable, ensuring the arc-shaped plate tightly fits the cable surface. This achieves stable clamping of cables of different specifications. The arc-shaped plate, made of elastic material, can evenly distribute pressure during clamping, reducing damage to the cable sheath, protecting the internal structure of the cable, and extending its service life. Furthermore, in the event of vibration in a mining environment, the spring can also act as a buffer, absorbing some of the vibration energy, further ensuring the stability of the cable under clamping conditions and guaranteeing the continuity and reliability of power transmission.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] Reference Figures 1-4 An embodiment of this utility model includes a support body 1, with oblique holes 2 at the bottom and one side of the support body 1. A fixing component 3 is provided on one side of the support body 1, and a fixing plate 4 is fixedly connected to the middle of one side of the support body 1. A clamping component 6 is provided on the top of the fixing plate 4. The fixing component 3 includes an oblique threaded cylinder 31, one end of which is connected to one side of the support body 1. An oblique rod 32 is threadedly connected inside the oblique threaded cylinder 31. Both ends of the oblique rod 32 are movably embedded inside the oblique holes 2. One end of the oblique rod 32 is connected to a circular plate 33, and one side of the circular plate 33 is in contact with one side of the oblique threaded cylinder 31.

[0020] Insert one end of the support body 1 into the mine wall and make the side of the support body 1 fit against the wall. Then rotate the diagonal rod 32 so that it spirals through the inside of the diagonal threaded cylinder 31 and is inserted into the diagonal hole 2. The diagonal rod 32, the support body 1 and the wall form a stable triangular support frame structure, which enhances the stability of the support on the wall.

[0021] Reference Figures 1-4 The clamping assembly 6 includes a base 61, the bottom end of which is fixedly connected to the top end of the fixing plate 4. A clamping plate 62 is provided on the top of the base 61. Threaded rods 63 are rotatably connected to both sides of the clamping plate 62. Threaded holes 64 are provided on both sides of the top end of the base 61 and the fixing plate 4. The bottom of the threaded rod 63 is threadedly connected to the inner wall of the threaded hole 64. Two arc-shaped plates 65 are provided between the base 61 and the clamping plate 62. A set of springs 66 is connected to one side of each of the two arc-shaped plates 65.

[0022] Reference Figures 1-4Two support plates 5 are fixedly connected to the bottom of the fixed plate 4, and one end of the support plate 5 is fixedly connected to the bottom of one side of the bracket body 1. The arc plate 65 is made of an elastic material to adapt to the clamping requirements of cables of different specifications and to reduce damage to the cables during clamping. The bottom of the threaded rod 63 is provided with a rotating handle, which allows the operator to rotate the threaded rod 63 to adjust the distance between the clamping plate 62 and the base 61. The bracket body 1, the fixed plate 4, and the support plates 5 are all made of high-strength metal materials to ensure the overall structural strength of the bracket and to meet the usage requirements of complex mining environments. One end of one set of springs 66 is fixedly connected to the top of the base 61, and one end of the other set of springs 66 is fixedly connected to the bottom of the clamping plate 62. When cable clamping is required, the operator uses a rotating handle located at the bottom of the threaded rod 63. The rotating handle is engaged with the threaded rod 63 and can be disassembled to separate the clamping plate 62 from the base 61. This allows the cable to be clamped between the two arc-shaped plates 65. Rotating the threaded rod 63 adjusts the distance between the clamping plate 62 and the base 61, ensuring that the arc-shaped plates 65, under the action of the spring 66, tightly and gently clamp the cable. This ensures the cable is stably fixed in the mining environment and guarantees the normal operation of power transmission. Working Principle: The support body 1 serves as the basic load-bearing structure of the entire support system. During installation, one end of the support body 1 is inserted into the mine wall, ensuring a tight fit between its side and the wall for initial positioning. One end of the inclined threaded cylinder 31 is firmly connected to one side of the support body 1. The inclined rod 32 is threadedly connected to the inclined threaded cylinder 31. During installation, rotating the inclined rod 32 causes it to rotate within the inclined threaded cylinder 31. As the inclined rod 32 rotates, its two ends move along the inclined holes 2 on the support body 1. Ultimately, both ends of the inclined rod 32 are movably embedded within the inclined holes 2, and the circular plate 33 connected to one end of the inclined rod 32 fits against one side of the inclined threaded cylinder 31. At this point, the inclined rod 32, the support body 1, and the mine wall together form a triangular support frame structure. Based on the principle of triangle stability, this structure significantly enhances the stability of the support on the wall, effectively resisting vibrations and external impacts that may occur in the mining environment. This ensures that the support body 1 will not easily loosen or shift, providing a solid foundation for subsequent cable fixing. When cable clamping is required, the operator removes the clamp 62, places the cable between the two arc-shaped plates 65, and then reinstalls the clamp 62. The operator then rotates the handle at the bottom of the threaded rod 63, causing the threaded rod 63 to rotate within the threaded hole 64, thereby adjusting the distance between the clamp 62 and the base 61. As the clamp 62 moves downwards, the distance between the two arc-shaped plates 65 gradually decreases. Because the arc-shaped plates 65 are elastic, and the spring 66 can expand and contract according to the applied force, when the cable enters between the two arc-shaped plates 65, the spring 66 adaptively adjusts according to the cable's diameter and shape. The spring 66 is compressed or stretched, causing the arc-shaped plates 65 to fit tightly against the cable surface, achieving stable clamping of cables of different specifications. Simultaneously, the arc-shaped plates 65, made of elastic material, reduce damage to the cable during clamping, protecting the cable's outer sheath and internal structure. In the event of vibration in a mining environment, the spring 66 also provides cushioning. When vibration is transmitted to the clamping assembly 6, the spring 66 can absorb some of the vibration energy through its own expansion and contraction, reducing the impact of vibration on the cable and ensuring that the cable is always in a stable clamping state, thus ensuring the continuity and reliability of power transmission.
