Description

Technical Field

[0001] This utility model relates to the field of cable hanging technology, and in particular to a self-locking, impact-resistant communication cable hanging device for mining. Background Technology

[0002] In underground coal mine roadways, especially in areas such as main inclined shafts, a large number of communication and monitoring cables typically need to be laid. Currently, the most common hanging methods are wire binding or direct suspension with ordinary hooks. These traditional methods have obvious drawbacks. First, wire binding is prone to loosening. Under the vibration and impact caused by the operation of underground equipment, personnel passage, or changes in ground stress, the cables are prone to falling off, shifting, or even becoming entangled, affecting communication safety. Second, ordinary hooks lack a locking function, and the cables may jump out of the hooks under their own weight or external forces, posing a safety hazard. Finally, the chaotic cable layout is not only detrimental to daily maintenance and standardized management, but may also hinder personnel evacuation and rescue in emergencies.

[0003] Therefore, there is an urgent need for a special cable hanging device that is easy to install, reliably fixed, can effectively resist vibration and impact caused by complex working conditions downhole, and has an anti-fall-off function. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing mining communication cable hanging devices usually have cables that are easy to loosen; poor impact resistance and easy to loosen; poor flexibility and inconvenient maintenance.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a mine self-locking impact-resistant communication cable hanging device, including a load-bearing base plate, an anchor plate at the rear end of the load-bearing base plate, hooks and straps on the load-bearing base plate. Two sets of first mounting holes are symmetrically opened on the load-bearing base plate. The hooks are detachably connected to the load-bearing base plate through the first mounting holes. Two sets of round holes are symmetrically opened on both sides of the first mounting holes on the load-bearing base plate. The round holes are used for the straps to pass through. The two hooks are arranged symmetrically side by side with their arc-shaped parts facing upward. The two hooks together form a gantry-type cable passage under the load-bearing base plate. The cable passes horizontally through the passage. The arc-shaped concave surface of the hook is used to support and initially limit the cable. The straps are used to further bind and limit the cable on both sides of the hook.

[0006] The beneficial effects of this utility model are: by combining the "gantry-type cable threading channel" with the "tie strap auxiliary locking", a double limit is achieved. First, the channel formed by the two side-by-side hooks provides lateral restraint to the cable, preventing it from moving laterally. Then, the tie strap passing through the round hole presses the cable bundle tightly from above, forming a second safety measure, which effectively solves the problem of cable jumping off due to vibration and demonstrates the self-locking nature of the device.

[0007] Furthermore, the load-bearing base plate is set horizontally, the anchor plate is set vertically, and the anchor plate is welded to the rear end of the load-bearing base plate.

[0008] Furthermore, an anti-slip pad is fitted to the rear end of the anchor plate, and a second mounting hole penetrating the anti-slip pad is symmetrically opened on the anchor plate.

[0009] Furthermore, a ring block is fixedly connected to the upper end of the hook, and a threaded head is fixedly connected to the upper end of the ring block.

[0010] Furthermore, a nut is threaded onto the outer side of the threaded head, and rubber washers are provided at the ends of the nut and the ring block that are close to each other.

[0011] Furthermore, the hook is threaded to the load-bearing base plate via a threaded head.

[0012] Furthermore, the nut and the rubber washer on the ring block together form a damping and shock absorption unit after tightening, which is used to absorb the vibration energy of the hook and provide anti-loosening friction.

[0013] Furthermore, the second mounting hole is used to install and fix the anchor plate to the tunnel wall.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: Anti-slip pads are installed between the anchor plate and the tunnel wall, utilizing the material's elasticity to absorb external macroscopic vibrations and prevent overall device slippage. At the hook's fastening point, the rubber washers between the nut and the ring block together form a damping and shock-absorbing unit, effectively absorbing and dissipating the vibration energy transmitted through the load-bearing base plate. The friction of the rubber prevents the nut from self-spinning and loosening, achieving the crucial impact resistance function and providing dual shock absorption and anti-loosening effects. The modular design allows for detachable connection between the hook and the load-bearing base plate via threaded heads and nuts, enabling adjustable hook spacing and quick replacement of individual components, greatly improving installation flexibility and maintenance efficiency.

[0019] like Figures 1-5 As shown, a mine-use self-locking impact-resistant communication cable hanging device includes a load-bearing base plate 1, an anchor plate 4 located at the rear end of the load-bearing base plate 1, hooks 2 and straps 3 located on the load-bearing base plate 1. Two sets of first mounting holes 5 are symmetrically opened on the load-bearing base plate 1. The hooks 2 are detachably connected to the load-bearing base plate 1 through the first mounting holes 5. Two sets of round holes 6 are symmetrically opened on both sides of the first mounting holes 5 on the load-bearing base plate 1. The round holes 6 are used for the straps 3 to pass through. The two hooks 2 are arranged symmetrically side by side with their arc-shaped parts facing upward. The two hooks 2 together form a gantry-type cable passage under the load-bearing base plate 1. The cable passes horizontally through this passage. The arc-shaped concave surface of the hook 2 is used to support and initially limit the cable. The straps 3 are used to further bind and limit the cable on both sides of the hook 2.

[0020] like Figures 2-4As shown, the load-bearing base plate 1 is horizontally positioned, and the anchor plate 4 is vertically positioned. The anchor plate 4 is welded to the rear end of the load-bearing base plate 1. An anti-slip pad 7 is attached to the rear end of the anchor plate 4. The anti-slip pad 7 is made of wear-resistant rubber, engineering plastics (such as nylon, ultra-high molecular weight polyethylene), or polyurethane. The anti-slip pad 7 fills the gaps in the contact surface through its elastic deformation. While achieving buffering and shock absorption, it utilizes the huge static friction force generated to fundamentally prevent the entire device from slipping and loosening due to vibration. A second anchor plate 4 is symmetrically positioned, penetrating the anti-slip pad 7. The upper end of the hook 2 is fixedly connected to the mounting hole 8, and the upper end of the ring block 9 is fixedly connected to the threaded head 10. The outer side of the threaded head 10 is threaded with a nut 11. The ends of the nut 11 and the ring block 9 that are close to each other are provided with rubber washers 12. The hook 2 is threadedly connected to the load-bearing base plate 1 through the threaded head 10. After the nut 11 and the rubber washers 12 on the ring block 9 are tightened, they together form a damping and shock absorption unit, which is used to absorb the vibration energy of the hook 2 and provide anti-loosening friction. The second mounting hole 8 is used to install and fix the anchor plate 4 to the tunnel wall.

[0021] Working principle: First, the workers use anchor bolts and other fasteners through the second mounting hole 8 on the anchor plate 4 to firmly install the entire device in the predetermined position on the roadway wall. At this time, the anti-slip pad 7 at the rear end of the anchor plate 4 is pressed down and fills the gap on the wall through its elastic deformation, which not only buffers the vibration, but also prevents the basic slippage of the entire device through huge static friction. Then, the communication cable to be laid is horizontally threaded into the "gantry-type cable channel" formed by two hooks 2 arranged side by side symmetrically below its load-bearing base plate 1. The weight of the cable is borne by the arc-shaped concave surface of the hook 2, which realizes the initial support and limitation of the cable. Next, nylon cable ties or similar straps are used as binding straps 3, which are passed through the round holes 6 on both sides of the first mounting hole 5 on the load-bearing base plate 1 to bind and lock the entire bundle of cables that has been placed in the hook 2 to the load-bearing base plate 1. This step constitutes a secondary auxiliary fixation of the cables, ensuring that even if a violent impact occurs, the cables will not jump out of the hook 2, thus realizing the mechanical self-locking of the device. Finally, during the long-term operation of the device, when the tunnel environment vibrates, the vibration energy will be effectively attenuated through two paths: one is absorbed by the anti-slip pad 7 at the anchor plate 4; the other is transmitted to the load-bearing base plate 1 and consumed by the damping and shock absorption unit composed of upper and lower rubber washers 12 at the connection of the hook 2, thereby ensuring that the nut 11 will never loosen, the hook 2 will always be stable, and the cable suspension will be absolutely safe.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
