Technical Field

[0001] The present application relates to the technical field of cable racks, and in particular to a pulley-supported cable rack structure. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and insulation layers, used to connect circuits, electrical appliances, etc. In the field of power facilities, the laying and management of cables are important links.

[0003] Existing cables are usually supported by fixed brackets or hangers during laying. However, the fixed support structure has poor adjustability during cable laying, making it difficult to control the direction and position of the cables, which reduces work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve or at least alleviate the problem that the existing cables are usually supported by fixed brackets or hangers during laying, but the fixed supporting structure has poor adjustability during cable laying, making it difficult to control the direction and position of the cables, resulting in reduced work efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pulley-supported cable rack structure comprises a crossbeam and a pulley assembly, wherein the pulley assembly is slidably connected to the crossbeam via a fixing assembly, wherein the fixing assembly comprises a slide groove provided on a side wall of one side of the crossbeam, wherein a threaded rod is provided in the slide groove, wherein both ends of the threaded rod are rotatably connected to the side walls of both sides of the slide groove, a slider is threadedly connected to the threaded rod, and an end of the slider away from the threaded rod is fixedly connected to the pulley assembly.

[0007] By adopting the above technical solution, when in use, the beam is installed on the wall, and then the cable is laid on the pulley assembly. The slider is made to slide in the slide groove by rotating the threaded rod, driving the pulley assembly to move on the beam to adjust the direction of the cable. This avoids the problem of poor adjustability and difficulty in controlling the direction of the cable when laying the cable, which leads to reduced work efficiency.

[0008] Optionally, the pulley assembly includes a rotating rod fixedly connected to an end of the sliding block away from the threaded rod, and a pulley body is rotatably arranged on the rotating rod.

[0009] By adopting the above technical solution, by laying the cable on the pulley body, when the cable is pulled, the cable drives the pulley body to rotate on the rotating rod, which can reduce the friction of the cable and prevent the cable from being severely worn and damaged.

[0010] Optionally, a bearing is sleeved on the rotating rod, an inner wall of the bearing is fixedly connected to the rotating rod, and an outer wall of the bearing is fixedly connected to an inner wall of the pulley body.

[0011] By adopting the above technical solution, the rotation speed of the pulley body on the rotating rod can be increased through the bearing.

[0012] Optionally, a side wall of the pulley body is provided with an annular wire groove.

[0013] By adopting the above technical solution, the annular wire groove can prevent the cable from shaking and falling off the pulley body when the cable is pulled.

[0014] Optionally, one end of the rotating rod away from the slider is fixedly connected to a connecting block, the connecting block and the upper surface of the slider are fixedly connected to the same U-shaped rotating shaft, and the vertical end and horizontal end of the U-shaped rotating shaft are both rotatably connected to guide wheels.

[0015] By adopting the above technical solution, the guide wheel on the U-shaped rotating shaft cooperates with the pulley body, so that the cable can be easily turned up, down, left and right, while reducing the friction between the cable and the guide wheel.

[0016] Optionally, one end of the threaded rod passes through the side wall of the slide groove and is fixedly connected to a rotating disk.

[0017] By adopting the above technical solution, the operator can conveniently rotate the threaded rod by means of the rotating disk, so that the slider moves in the slide groove.

[0018] Optionally, one end of the cross beam is located on one side of the threaded rod and is fixedly connected to a telescopic rod, a side wall of one side of the rotating disk is provided with a plurality of through holes in an annular array, and one end of the telescopic rod away from the cross beam is located in the through hole.

[0019] By adopting the above technical solution, after the slider is moved to a suitable position, the threaded rod can be fixed by pulling out the telescopic rod and passing one end of the telescopic rod through the through hole to prevent the threaded rod from rotating during use and causing the slider to shift.

[0020] Optionally, one end of the telescopic rod away from the crossbeam is threadedly connected to a limit plate.

[0021] By adopting the above technical solution, after the telescopic rod passes through the through hole, the limit plate is threadedly connected to one end of the telescopic rod, which can prevent the telescopic rod from automatically sliding out of the through hole, resulting in the inability to fix the threaded rod.

[0022] In summary, the beneficial effects of this application are as follows:

[0023] 1. The present application uses the coordination of structures such as the slide groove, the threaded rod and the slider. When in use, the beam is installed on the wall, and the cable is laid on the pulley assembly. The threaded rod is rotated to make the slider slide in the slide groove, driving the pulley assembly to move on the beam to adjust the direction of the cable, thereby avoiding the problem of poor adjustability and difficulty in controlling the direction of the cable when laying the cable, which reduces the work efficiency.

[0024] 2. The guide wheel on the U-shaped rotating shaft cooperates with the pulley body to facilitate the cable to turn up, down, left, and right, while reducing the friction between the cable and the guide wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] See also Figure 1-3 A pulley-supported cable rack structure includes a beam 1 for support and a pulley assembly for placing cables. The pulley assembly is slidably connected to the beam 1 through a fixed assembly. The fixed assembly includes a slide groove 2 opened on a side wall of one side of the beam 1. A threaded rod 3 is provided in the slide groove 2 for driving an object to move in the slide groove 2. Both ends of the threaded rod 3 are rotatably connected to the side walls of the slide groove 2. A slider 4 is threadedly connected to the threaded rod 3. The slider 4 fits against the side wall of the slide groove 2 to prevent shaking. The end of the slider 4 away from the threaded rod 3 is fixedly connected to the pulley assembly.

[0031] When in use, the beam 1 is installed on the wall, and the cable is then laid on the pulley assembly. The slider 4 is made to slide in the slide groove 2 by rotating the threaded rod 3, thereby driving the pulley assembly to move on the beam 1 to adjust the direction and position of the cable, thereby avoiding as much as possible the problem of poor adjustability and difficulty in controlling the direction and position of the cable during cable laying, which leads to reduced work efficiency.

[0032] Reference Figure 2 The pulley assembly includes a rotating rod 5 fixedly connected to the end of the slider 4 away from the threaded rod 3, and a pulley body 6 is rotatably arranged on the rotating rod 5. By laying the cable on the pulley body 6, when the cable is pulled, the cable drives the pulley body 6 to rotate on the rotating rod 5, which can reduce the friction of the cable and prevent the cable from being severely worn and damaged.

[0033] Reference Figure 2 A bearing 7 is sleeved on the rotating rod 5, the inner wall of the bearing 7 is fixedly connected to the rotating rod 5, and the outer wall of the bearing 7 is fixedly connected to the inner wall of the pulley body 6. The bearing 7 can increase the rotation speed of the pulley body 6 on the rotating rod 5.

[0034] Reference Figure 2 The side wall of the pulley body 6 is provided with an annular wire groove 8, through which the cable can be prevented from shaking and detaching from the pulley body 6 when the cable is pulled.

[0035] Reference Figure 2 The end of the rotating rod 5 away from the slider 4 is fixedly connected to a connecting block 9, and the connecting block 9 and the upper surface of the slider 4 are fixedly connected to the same U-shaped rotating shaft 10. The vertical end and the horizontal end of the U-shaped rotating shaft 10 are rotatably connected to guide wheels 11. The guide wheels 11 on the U-shaped rotating shaft 10 cooperate with the pulley body 6 to facilitate the cable to turn up, down, left, and right, while reducing the friction between the cable and the guide wheels 11.

[0036] Reference Figure 3 One end of the threaded rod 3 passes through the side wall of the slide groove 2 and is fixedly connected to a rotating disk 12. Through the rotating disk 12, it is convenient for an operator to rotate the threaded rod 3 to move the slider 4 in the slide groove 2.

[0037] Reference Figure 3 One end of the cross beam 1 is located on one side of the threaded rod 3 and is fixedly connected to a telescopic rod 13. A plurality of through holes 14 in a circular array are opened on the side wall of one side of the rotating disk 12. The end of the telescopic rod 13 away from the cross beam 1 is located in the through hole 14. After the slider 4 is moved to a suitable position, the threaded rod 3 can be fixed by pulling out the telescopic rod 13 and passing one end of the telescopic rod 13 through the through hole 14 to prevent the threaded rod 3 from rotating during use and causing the slider 4 to shift.

[0038] Reference Figure 3The end of the telescopic rod 13 away from the crossbeam 1 is threadedly connected to the limit plate 15. After the telescopic rod 13 passes through the through hole 14, the limit plate 15 is threadedly connected to one end of the telescopic rod 13 to prevent the telescopic rod 13 from automatically sliding out of the through hole 14, resulting in the inability to fix the threaded rod 3.
