Description

Technical Field

[0001] The present application relates to the technical field of mobile device cable protection, and in particular to a mobile device cable well cable protection device. Background Art

[0002] At present, the working characteristics of mobile equipment such as stackers, unloaders, shuttle belt conveyors, impeller feeders, etc. in raw material yards are long-stroke reciprocating movements. In order to ensure their efficient and safe operation, thereby ensuring the continuous production tasks of the factory, the safety and reliability of their power supply methods are particularly important.

[0003] Currently, the mainstream ways to power mobile devices include safety busbars, trolley busbars, cable reels and cable drag chains. Among them, the cable reel power supply method has a relatively compact structure, which is convenient for the arrangement of the cable reel on the host and easy to install and maintain. It is also fully functional. The cable is a multi-core flat cable that can be used for power supply and communication of mobile devices at the same time. The flat cable is connected from the cable well to power the mobile device. When the mobile device is away from the cable well, the cable is dragged on the ground.

[0004] In the related art, when a cable reel is used to power a mobile device, the cable moves back and forth with the mobile device, is repeatedly dragged and bent on the ground, stepped on and pressed by people and vehicles, and the cable has a high frequency of back and forth friction against the side walls and wellhead of the cable well, which can easily cause cable damage. The safety of the cable cannot be guaranteed after it is damaged. If it is not discovered in time, it can easily cause production safety accidents, so there is room for improvement.

[0006] The present application provides a mobile equipment cable well cable protection device adopts the following technical solution:

[0007] A cable protection device for a cable well of a mobile equipment, comprising a clamping roller group arranged at the wellhead of the cable well, the clamping roller group comprising four clamping rollers, a clamping frame and four clamping rotating shafts, a slide groove for the sliding of the clamping frame is opened on the inner wall of the wellhead of the cable well, the four clamping rollers correspond to the four clamping rotating shafts respectively, the four clamping rotating shafts are rotatably connected to the clamping frame, the clamping rollers are connected to the corresponding clamping rotating shafts, a clamping area for the cable to pass through is formed between the four clamping rollers, and guide roller groups for guidance are arranged on both sides of the clamping roller group.

[0008] When a cable reel is used to power a mobile device, the cable moves back and forth with the mobile device, is repeatedly dragged and bent on the ground, stepped on and pressed by people and vehicles, and the cable rubs against the side walls of the cable well and the wellhead at a high frequency, which can easily cause cable damage. After the cable is damaged, the safety problem cannot be guaranteed. If it is not discovered in time, it can easily cause production safety accidents. By adopting the above technical solution, the clamping roller group is slidably installed at the wellhead of the cable well, and the clamping roller group consists of four clamping rollers, a clamping frame and four clamping rotating shafts. When the cable moves back and forth with the mobile device, the cable passes through the guide roller group and the clamping roller group and extends into the cable well. The clamping roller group and The guide roller group cooperates to avoid friction between the cable and the edge of the cable well, and at the same time, the clamping roller group slides as the cable swings back and forth, reducing the friction between the cable and the inner wall of the cable well; through the arrangement of clamping rollers, clamping frames, clamping shafts and guide roller groups, direct friction between the cable and the edge of the cable well or other objects can be avoided, and the sliding friction during movement is converted into rolling friction.

[0017] Optionally, the plurality of guide brackets are arranged from low to high in a direction away from the clamping roller group, and each of the guide rollers is provided with a concave notch.

The number of guide rollers 41, guide brackets 42 and guide shafts 43 is the same and corresponds to each other. In this embodiment, the number of guide rollers 41 is at least three groups. The guide brackets 42 are installed and fixed at the wellhead of the cable well 2. The guide brackets 42 can be installed by welding or bolting. The guide rollers 41 are sleeved and fixed on the guide shafts 43. The guide shafts 43 are rotatably installed on the guide brackets 42 through bearings to guide the cables to correctly enter and exit the cable well 2, ensure that the cables move along a predetermined path, reduce the bending and twisting of the cables, and thus reduce the wear of the cables.

[0035] Reference Figure 1 and Figure 2 Each guide roller 41 has a concave notch 8 on its surface, which reduces the contact area between the cable and the roller, thereby reducing friction resistance and reducing cable wear.

[0036] Reference Figure 1and Figure 2 In this embodiment, several guide brackets 42 of the same group are arranged from low to high in the direction away from the clamping roller group 1. The arrangement of the guide brackets 42 from low to high can better adapt to the movement requirements of the cable, reduce wear and friction, and ensure that the cable always remains in the correct position.

The plurality of clamping rollers 11 and the plurality of clamping shafts 13 correspond to each other one by one. The clamping rollers 11 are sleeved and fixed on the clamping shafts 13. The four clamping shafts 13 are rotatably mounted on the clamping frame 12 through bearings. A slide groove 21 is provided at the wellhead of the cable well 2. The clamping frame 12 is slidably connected in the slide groove 21. In this embodiment, the clamping frame 12 can realize corresponding sliding movements through pulleys. In this embodiment, the four clamping rollers 11 are sequentially surrounded into a whole. A clamping area 3 for the cable to pass through is formed between the four clamping rollers 11, which is used to move with the swing of the cable, thereby limiting the swing amplitude of the cable, further reducing the friction between the cable and the inner wall of the cable well 2, and effectively protecting the cable.

The channel steel support plates 122 are connected to the channel steel seat 121 through fixing bolts 9 to form a solid supporting structure, which reduces the shaking or displacement of the clamping and protecting rollers 11 during use.

[0039] Reference Figure 1 and Figure 3 Each clamping roller 11 is fixedly sleeved with an elastic cushion sleeve 10, which may be made of rubber material to provide sufficient friction to reduce the cable from slipping or unnecessary displacement during movement, thereby ensuring stable transmission of the cable on the clamping roller 11. At the same time, a buffer layer is formed between the cable and the clamping roller 11, which can absorb part of the impact and friction and reduce wear and damage to the cable surface.

[0040] Reference Figure 1Two arc-shaped baffles 5 are installed below the clamping roller group 1. The two arc-shaped baffles 5 are welded and fixed in the cable well 2. The two arc-shaped baffles 5 are arranged opposite to each other, and an arc-shaped area 6 for limiting the cable is formed between the two arc-shaped baffles 5, which is used to effectively limit the swing amplitude of the cable in the vertical direction and guide the direction of the cable to a certain extent, thereby reducing the collision and friction between the cable and the side wall or bottom of the cable well 2, thereby reducing the damage that the cable may suffer.

[0041] Reference Figure 1 A protective round tube 51 is welded and fixed at the end of each arc-shaped baffle plate 5, and the two protective round tubes 51 are arranged opposite to each other. In this embodiment, the protective round tube 51 is installed at one end of the corresponding arc-shaped baffle plate 5 close to the bottom of the cable well 2, so that the contact surface between the cable and the arc-shaped baffle plate 5 becomes smoother, and the cable can slide more smoothly when moving, reducing the resistance caused by friction, thereby reducing the possibility of wear and tear and extending the service life of the cable.

[0042] Reference Figure 1 and Figure 4 A plurality of side roller groups 7 are installed between the two arc-shaped baffles 5. The plurality of side roller groups 7 are sequentially installed on the inner wall of the cable well 2. Each side roller group 7 includes a side roller 71, a side bracket 72 and a side shaft 73. The side roller 71 is sleeved and fixed on the side shaft 73. In this embodiment, the side rollers 71 and the guide rollers 41 are both ceramic rollers. The side shaft 73 is rotatably installed on the side bracket 72 through bearings. The side bracket 72 is fixed to the inner wall of the cable well 2 by welding or bolts, so as to reduce the friction and wear of the cable, so that the sliding friction between the cable and the inner wall of the cable well 2 is changed to the rolling friction with the side roller 71, thereby reducing the wear of the cable. At the same time, it provides stable support and guidance and reduces the movement resistance.

[0043] The implementation principle of a cable protection device for a cable well of a mobile device in an embodiment of the present application is as follows: when the cable moves back and forth with the mobile device, the cable passes through the guide roller group 4 and the clamping roller group 1 and extends into the cable well 2. The clamping roller group 1 and the guide roller group 4 cooperate to avoid friction between the cable and the well edge of the cable well 2. At the same time, the clamping roller group 4 slides as the cable swings back and forth. The arc-shaped baffle 5 limits the swing amplitude of the cable, and the side roller group 7 reduces the friction between the cable and the inner wall of the cable well 2, thereby protecting the cable when it moves; by setting the clamping roller 11, the clamping frame 12, the clamping shaft 13 and the guide roller group 4, direct friction between the cable and the well edge of the cable well 2 or other objects can be avoided, and the sliding friction during the movement process can be converted into rolling friction. At the same time, the synergistic effect of the clamping roller group 1 and the guide roller group 4 can also limit the swing amplitude of the cable, further reduce the friction between the cable and the inner wall of the cable well 2, effectively protect the cable, reduce its damage during movement, and extend its service life, thereby improving the safety and stability of the equipment.
