Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable construction equipment, in particular to a cable pay-out structure. Background Art
[0002] Cables include electric wires and cables. Cable pay-off structures are commonly used tools in cable laying projects. In reality, there are various types of cable pay-off devices. At present, the traditional cable laying is to use a cable rack that is rotated and installed inside the pay-off space. Then, the cable rack is rotated by pulling the cables, so that the cables can be quickly detached from the cable rack for laying. However, during the rotation of the cable rack, the cables inside it are quickly pulled out, which easily causes the inner ring of cables to fall off prematurely. Once too many cables fall off the inner ring, the cables will become tangled when they are pulled out, affecting the cable laying operation. Utility Model Content

[0012] Preferably, a mounting sleeve is fixedly installed at the bottom of the line-releasing limit frame, and the mounting sleeve is rotatably connected to the line-releasing support rod through a bearing. A limiting groove is provided at the bottom end of the mounting sleeve, and the mounting sleeve is clamped to the surface of the limiting protrusion through the limiting groove. The rotation angle of the mounting sleeve can be limited by the limiting action of the limiting protrusion and the limiting groove.

[0025] Please see the attached Figure 1 To the attached Figure 5 As shown, the utility model provides a cable pay-out structure, comprising:
[0026] The wire-paying bracket 1 has a roller 11 rotatably installed at the bottom of the wire-paying bracket 1, and a handle 12 is provided above the roller 11. The wire-paying bracket 1 can be pushed or pulled to move by the roller 11 and the handle 12. A lower limit ring 13 and an upper limit ring 14 are fixedly provided on the surface of the wire-paying bracket 1. A guide groove 15 is provided between the lower limit ring 13 and the upper limit ring 14. A cable rack 4 is rotatably provided inside the wire-paying bracket 1. The lower limit ring 13 and the upper limit ring 14 are provided on the opening side of the cable rack 4. A wire-paying support rod 2 is fixedly installed on the surface of the wire-paying bracket 1. The wire-paying support rod 2 is provided on the side of the cable rack 4 close to the lower limit ring 13. A limiting protrusion 21 is fixedly provided on the surface of the wire-paying support rod 2.
[0027] The wire-paying limit frame 3 is rotatably arranged at the top of the wire-paying support rod 2. A mounting sleeve 32 is fixedly installed at the bottom of the wire-paying limit frame 3. The mounting sleeve 32 is rotatably connected to the wire-paying support rod 2 through a bearing. A limiting groove 33 is provided at the bottom end of the mounting sleeve 32. The mounting sleeve 32 is clamped on the surface of the limiting protrusion 21 through the limiting groove 33. The rotation angle of the mounting sleeve 32 can be limited by the limiting action of the limiting protrusion 21 and the limiting groove 33. A limiting wheel 31 is rotatably installed inside the wire-paying limit frame 3. A groove is provided on the surface of the limiting wheel 31. At least one group of limiting wheels 31 is provided, such as two groups. The cable can pass between the two groups of limiting wheels 31.
[0028] The pressure roller 5 is arranged inside the cable rack 4, and a central axis 51 is provided inside the pressure roller 5 for rotation. The central axis 51 is fixedly connected to the sleeve 53 through a connecting rod 52, and the sleeve 53 is slidably sleeved on the surface of the wire-paying bracket 1. A supporting spring 55 is provided between the sleeve 53 and the lower limit ring 13, and the supporting spring 55 is sleeved on the surface of the wire-paying bracket 1. Under the elastic force of the supporting spring 55, the initial position of the sleeve 53 abuts against the upper limit ring 14, and a guide slider 54 is fixedly provided inside the sleeve 53. The guide slider 54 is slidably set inside the guide slot 15. The sleeve 53 can be prevented from rotating on the surface of the wire-paying bracket 1 through the limiting action of the guide slider 54 and the guide slot 15.
[0029] Example 1:
[0030] The present invention proposes a cable pay-off structure. When the cable is loaded into the cable rack 4, the holding spring 55 presses the pressure roller 5 against the inner ring of the cable through the sliding sleeve 53 and the connecting rod 52. When paying out the cable, one end of the cable is passed between the two sets of limiting wheels 31, and then the cable rack 4 is rotated by pulling the cable to make the cable detach from the inside of the cable rack 4. During the rotation of the cable rack 4, the pressure roller 5 rolls along the inner ring of the cable, and under the supporting action of the holding spring 55, the pressure roller 5 always presses the inner ring of the cable, thereby avoiding the problem of the cable in the inner ring falling off prematurely and causing the cable to become knotted during the pay-off process.
[0031] Example 2:
[0032] On the basis of Example 1, by rotatably connecting the wire-paying limit frame 3 with the wire-paying support rod 2, during the wire-paying process, when the direction of the wire-paying changes slightly, the cable can drive the wire-paying limit frame 3 to rotate, so that the direction of the wire-paying limit frame 3 is consistent with the wire-paying direction, avoiding the problem of friction between the cable and the side wall of the wire-paying limit frame 3 due to changes in the wire-paying direction.
[0033] Example 3:
[0034] On the basis of Example 2, by setting a limiting protrusion 21 and a limiting groove 33, the limiting angle of the wire-releasing limiting frame 3 is limited, thereby avoiding the problem that during the wire-releasing process, the wire-releasing limiting frame 3 rotates too much due to the cable being loose or tight, and the cable is entangled on the surface of the wire-releasing limiting frame 3.
[0035] Working principle: The cable pay-off structure is a tool commonly used in cable laying projects. The utility model proposes a cable pay-off structure. When the cable is loaded into the cable rack 4, the supporting spring 55 presses the pressure roller 5 against the inner ring of the cable through the sliding sleeve 53 and the connecting rod 52. When paying out the cable, one end of the cable is passed between the two sets of limiting wheels 31, and then the cable rack 4 is driven to rotate by pulling the cable, so that the cable is disengaged from the inside of the cable rack 4. During the rotation of the cable rack 4, the pressure roller 5 rolls along the inner ring of the cable, and under the supporting action of the supporting spring 55, the pressure roller 5 always presses the inner ring of the cable. When the direction of paying out changes slightly, the cable can drive the paying-out limit frame 3 to rotate, so that the direction of the paying-out limit frame 3 is consistent with the paying-out direction, avoiding the problem of friction between the cable and the side wall of the paying-out limit frame 3 due to changes in the paying-out direction.
