Description

Technical Field

[0001] This utility model relates to the field of protection for cables used in coal mines, and specifically to a cable protection device. Background Technology

[0002] Currently, the power cables supplying the transport machinery are laid on the ground. Due to their length and weight, these cables can hinder the movement of technicians within the mine, potentially causing them to trip. Furthermore, the cables' placement on the ground or their insufficient suspension height can lead to them being squeezed or damaged during the movement of some mobile machinery, posing a potential hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a cable protection device that solves the problem of unreasonable cable laying.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cable protection device includes a main body, a flipping component, and a telescopic cylinder. The flipping component is rotatably connected to the main body, and one end of the telescopic cylinder is hinged to the main body, while the other end is rotatably connected to the flipping component. The telescopic cylinder drives the flipping component to rotate relative to the main body through changes in its extension and retraction posture.

[0006] Furthermore, the main body includes two side plates, a back plate, and a bottom plate, with the side plates and bottom plate both mounted on the bottom plate. The side plates are respectively positioned on both sides of the back plate. The back plate is provided with a U-shaped hole and two elongated holes, with the elongated holes located on both sides of the U-shaped hole.

[0007] Furthermore, the flipping component includes a flipping part and a transmission part; the flipping part includes a roller and a rotating arm, the transmission part includes a rocker arm and a rocker rod, the two sides of the roller are rotatably connected to the front end of the rotating arm, the rear end of the rotating arm is provided with a transmission rod, the transmission rod passes through the side plate and is connected to the rocker arm, and the telescopic end of the telescopic cylinder is hinged to the rocker rod provided on the rocker arm.

[0008] Furthermore, the flipping component includes a flipping part and a transmission part; the flipping part includes two rollers and a rotating arm, the transmission part includes a rocker arm and a rocker rod, one of the rollers is rotatably connected to the front end of the rotating arm on both sides, and the other roller is rotatably connected to the rear end of the rotating arm on both sides; a transmission rod is provided at the rear end of the rotating arm, the transmission rod passes through the side plate and is connected to the rocker arm, and the telescopic end of the telescopic cylinder is hinged to the rocker rod provided on the rocker arm.

[0010] Furthermore, the main body is provided with a guide hole, which is arc-shaped, and the rocker arm is provided with a guide block, which can move along the guide hole.

[0011] By adopting the above technical solution, the beneficial technical effects of this utility model are:

[0012] This invention fixes the main body through an elongated hole, then places the cable on the flipping component. When it is necessary to increase the cable laying height, the fixing height of the main body can be changed through the elongated hole, or the flipping component can be flipped using a telescopic cylinder to increase the cable laying height. This avoids the cable interfering with the technicians' walking operations underground, and also prevents mobile machinery from squeezing or damaging the cable. This invention improves the cable laying height and can change the cable laying height, effectively adapting to different mobile machinery operating heights and improving cable safety.

[0017] Example 1

[0018] like Figure 1As shown, a cable protection device includes a main body 1, a flipping component 2, and a telescopic cylinder 3. The flipping component 2 is rotatably connected to the main body 1, and the cable is placed on the flipping component 2. One end of the telescopic cylinder 3 is hinged to the main body 1, and the other end is rotatably connected to the flipping component 2. The telescopic cylinder 3 drives the flipping component 2 to rotate relative to the main body 1 through its extension and retraction posture changes. The main body 1 includes two side plates 11, a back plate 12, and a bottom plate 13. The side plates 11 and the bottom plate 13 are both disposed on the bottom plate 13, and the side plates 11 are respectively located on both sides of the back plate 12. The back plate 12 has a U-shaped hole 14 and two elongated holes 15, which are vertically arranged and located on both sides of the U-shaped hole 14. The height of the cable is lower than the highest point of the two side plates 11, and the side plates 11 can limit the cable and prevent the cable from slipping off the side plates 11. The U-shaped hole 14 allows the cable laid on the flipping component 2 to pass through. The main body 1 is fixed through the elongated hole 15, and the fixing height of the main body 1 can be changed according to the different fixing positions of the elongated hole 15, thus changing the cable laying height to adapt to mobile housings of different heights. After the main body 1 is fixed, if the cable is still too low during the movement of the coal mining machine and the cable laying height needs to be increased, the telescopic cylinder 3 extends, and the flipping part 2 rotates around the connection point with the main body 1. After the flipping part 2 rotates, the cable laying height is increased, making it easier for mobile machinery such as the coal mining machine to pass through, and the mobile machinery such as the coal mining machine will not squeeze or damage the cable.

[0019] The flipping component 2 includes a flipping part and a transmission part. The flipping part includes a roller 21 and a rotating arm 22. The transmission part includes a rocker arm 23 and a rocker rod 24. The two sides of the roller 21 are rotatably connected to the front end of the rotating arm 22, allowing the roller 21 to rotate relative to the rotating arm 22, thus improving the smoothness of the cable's lateral movement. A transmission rod 25 is provided at the rear end of the rotating arm 22. The transmission rod 25 passes through the side plate 11 and is connected to the rocker arm 23. The telescopic end of the telescopic cylinder 3 is hinged to the rocker rod 24 provided on the rocker arm 23. The main body 1 also includes a fixing plate 26, on which a hinged base 27 is provided. The telescopic cylinder 3 is hinged to the hinged base 27. When the cable laying height needs to be adjusted, the telescopic cylinder 3 will extend, and the fixed end of the telescopic cylinder 3 will rotate relative to the hinge base 27. The telescopic end of the telescopic cylinder 3 will provide thrust to the rocker arm 24. The rocker arm 24 will drive the rocker arm 23 to rotate around the transmission rod 25. The transmission rod 25 will rotate in the side plate 11 of the main body 1, and the transmission rod 25 will drive the rotating arm 22 to rotate, causing the roller 21 located at the rear end of the rotating arm 22 to rotate, ultimately achieving the purpose of raising the cable height.

[0020] like Figure 2As shown, the main body 1 is provided with a guide hole 28, which is arc-shaped. The rocker arm 24 is provided with a guide block 29, which can move along the guide hole 28. When the telescopic cylinder 3 extends, the rocker arm 23 rotates, and the guide block 29 fixed on the rocker arm 23 also rotates with the rocker arm 23. To improve the controllability of the rotation of the rocker arm 23, the guide block 29 moves in the guide hole 28. The guide hole 28 is set along the movement trajectory of the guide block 29 to improve the stability of the rotation of the rocker arm 23.

[0021] Example 2

[0022] like Figure 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the flipping part includes two rollers 21 and a rotating arm 22, and the transmission part includes a rocker arm 23 and a rocker rod 24. The two sides of one roller 21 are rotatably connected to the front end of the rotating arm 22, and the two sides of the other roller 21 are rotatably connected to the rear end of the rotating arm 22. A transmission rod 25 is provided at the rear end of the rotating arm 22. The transmission rod 25 passes through the side plate 11 and connects to the rocker arm 23. The telescopic end of the telescopic cylinder 3 is hinged to the rocker rod 24 located on the rocker arm 23. When the cable laying height needs to be adjusted, the telescopic cylinder 3 extends, and the fixed end of the telescopic cylinder 3 rotates relative to the hinged base 27. The telescopic end of the telescopic cylinder 3 provides thrust to the rocker rod 24, which in turn drives the rocker arm 23 to rotate around the transmission rod 25. The transmission rod 25 rotates within the side plate 11 of the main body 1, and the transmission rod 25 drives the rotating arm 22 to rotate, causing the two rollers 21 located on the rotating arm 22 to rotate respectively, ultimately achieving the purpose of raising the cable height. The purpose of setting two rollers 21 on the rotating arm 22 is to allow the two rollers 21 to rotate separately when the cable needs to move laterally, thereby improving the smoothness of the cable movement.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
