Description

Technical Field

[0001] This utility model belongs to the field of cable support technology and relates to a cable support device. Background Technology

[0002] On the roof of industrial plants, tow cables are widely used for power transmission of mobile electrical equipment such as overhead cranes and electric hoists. Currently, steel wire ropes are commonly used to support the tow cables. When the span of some plants is large, the weight of the cable and the steel wire rope can easily cause the middle of the steel wire rope to bend downwards during the movement of the cable. This can cause the cable hanging rings to pile up and become stuck. When the electric hoist moves, the corresponding ends of the cable will be subjected to a large tensile force, which can break the cable and cause equipment failure or safety accidents. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art that cable-supporting wire ropes are prone to bending downwards under gravity, causing accidents, by providing a cable-supporting device.

[0004] Therefore, the present invention adopts the following technical solution: A cable support device includes a guide rail, on which an electric hoist is mounted. The electric hoist can move back and forth along the length of the guide rail. A cable tensioning wire is provided on one side of the guide rail along the length of the guide rail. A cable is connected to the electric hoist. Multiple hanging rings are provided on the cable along the length of the cable. The hanging rings are suspended on the cable tensioning wire and can move back and forth along the length of the cable tensioning wire. A connecting frame is provided on the electric hoist, and a movable support roller is provided on the connecting frame. The movable support roller abuts against the bottom of the cable tensioning wire.

[0005] Furthermore, the movable support roller is arranged perpendicular to the cable tensioner.

[0006] Furthermore, the surface of the movable support roller is formed with a corrugated surface.

[0007] Furthermore, each end of the cable tensioner is provided with a bracket, and the bracket is provided with a fixed support roller, which abuts against the bottom end of the cable tensioner.

[0008] The beneficial effects of this utility model are as follows: by setting a movable support roller on the electric hoist and setting fixed support rollers at both ends of the cable tension line, the cable tension line can be supported at three points, which can effectively prevent long cable tension lines from bending downward under external force and causing cable damage; by supporting the cable with rotatable support rollers, cable wear can be prevented; the result is simple, the manufacturing cost is low, and the use effect is good.

Detailed Implementation

[0010] The present invention will now be described in detail with reference to the accompanying drawings: like Figure 1 As shown, a cable support device includes a guide rail 1, on which an electric hoist 2 is mounted. The electric hoist 2 can move back and forth along the length of the guide rail 1. A cable tensioner 3 is provided on one side of the guide rail 1 along its length. The electric hoist 2 is connected to a cable 4 for supplying power to the electric hoist. Multiple hanging rings 5 ​​are provided on the cable 4 along its length. The hanging rings 5 ​​are suspended on the cable tensioner 3 and can move back and forth along the length of the cable tensioner 3, i.e., the cable tensioner 3 passes through the hanging rings 5. When the electric hoist 2 moves, an external force can be applied to one end of the cable tensioner 3, causing the cable tensioner 3 to move under the action of the external force. The hanging rings 5 ​​move along the length of the cable tensioner 3 under the action of the external force. The electric hoist 2 is provided with a connecting... The frame 6 and the connecting frame 6 are equipped with a movable support roller 7. The movable support roller 7 is set perpendicular to the cable tension 3 and abuts against the bottom of the cable tension 3. The movable support roller 7 can move with the electric hoist 2. The movable support roller 7 can support the corresponding parts of the cable tension 3, effectively preventing the cable tension 3 from bending downward under the action of gravity. When the movable support roller 7 moves with the electric hoist 2, the movable support roller 7 rotates under the action of friction with the cable tension 3, which can effectively prevent wear on the cable tension 3. In order to increase the friction between the movable support roller 7 and the cable tension 3, a corrugated surface 10 is formed on the surface of the movable support roller 7, which improves the friction between the movable support roller 7 and the cable tension 3 and ensures that the movable support roller 7 rotates during the movement.

[0011] A bracket 8 is provided at each end of the cable tension 3. A fixed support roller 9 is provided on the bracket 8. The fixed support roller 9 abuts against the bottom end of the cable tension 3 to support the two ends of the cable tension 3. The cable tension 3 is supported by the rotatable fixed support roller 9, which can prevent wear on the cable tension 3.

[0012] The method of using this utility model is as follows: When the electric hoist 2 moves on the guide rail 1, the moving support roller 7 also moves simultaneously with the electric hoist 2, supporting the corresponding position of the cable tension 3. During the movement, the moving support roller 7 rotates under the action of friction without wearing down the cable tension 3. That is, by using one moving support roller 7 and two fixed support rollers 9, the cable tension 3 is supported at three points, which can effectively prevent the cable tension 3 from bending downward under its own weight and the weight of the cable 4, thereby effectively preventing the cable from being damaged under tension, and thus preventing equipment failure or safety accidents.
