Description

Technical Field

[0001] This application relates to the field of power cable technology, and in particular to a layered combing and fastening device for special grade cables. Background Technology

[0002] In cable applications, there are many situations where a cable clamping device that is easy to install and operate is required. For example, in wind turbine generator sets, the cable from the nacelle to the bottom of the tower is quite long and has a large weight hanging down naturally, requiring auxiliary force to fasten it. In addition, there are many cables, and good heat dissipation needs to be considered when fastening them. Furthermore, there are many types of wire diameters and limited available space, so it is also necessary to ensure that cables of different diameters can be easily clamped.

[0003] Existing cable layering and fastening devices typically use cable clamps to secure cables during use. However, these clamps are prone to loosening over time, leading to cable loosening. Additionally, when the clamping force is high, friction between the cable and the clamp can cause wear and damage to the cable's outer wall, making the device inconvenient for users. Utility Model Content

[0004] This application provides a layered combing and fastening device for special grade cables to solve the problems of existing cable layered combing and fastening devices, which generally use corresponding cable clamps to fix and hold the cables during use, thereby achieving the cable fixing operation. However, during use, the fixing clamps are prone to loosening during long-term clamping, which can lead to the cable loosening. At the same time, when the clamping force is large during the clamping process, the friction between the cable and the clamp can easily cause wear and damage to the outer wall of the cable.

[0005] This application provides a layered combing and fastening device for special grade cables, including a fixing body. A first rotating wheel is installed at one end of the fixing body, a handwheel is installed at one end of the first rotating wheel, a connecting rod is fixed at one end of the first rotating wheel, a bidirectional lead screw is installed at one end of the connecting rod, a lead screw nut is sleeved on the outer wall of the bidirectional lead screw, a movable slider is fixed on the outer wall of the lead screw nut, a movable frame is installed at the top of the movable slider, an mounting frame is installed at one end of the movable frame, a return spring is installed on the inner wall of the mounting frame, a positioning clamp is installed at one end of the mounting frame, and a positioning screw is fixed on one side of the first rotating wheel.

[0006] Preferably, the two ends of the return spring are connected to mounting plates.

[0007] Preferably, a limiting groove is provided on one side of the main body of the fixture.

[0008] Preferably, the positioning screw has a tightening nut threaded onto its outer surface.

[0009] Preferably, a second rotating wheel is installed at the end of the fixture body away from the first rotating wheel.

[0010] Preferably, a limiting groove is formed inside the main body of the fixture.

[0011] Preferably, the positioning clamp holds the cable body on one side.

[0012] Beneficial effects:

[0013] Considering that existing cable layering and fastening devices generally use corresponding cable clamps to fix and hold cables during use, the cables are prone to loosening during long-term use, which can lead to cable loosening. At the same time, when the clamping force is large, the friction between the cable and the clamp can easily cause wear and damage to the outer wall of the cable.

[0014] When it is necessary to fix the cable body, the cable body can be inserted between the two sets of positioning clamps inside the fixing body. Then, by turning the handwheel, the first rotating wheel is rotated, causing the connecting rod and the double-acting screw to rotate. The rotation of the double-acting screw causes the two sets of screw nuts at both ends of the outer wall of the double-acting screw to move closer to each other in a straight line along the outer wall of the double-acting screw. Under the action of the screw nuts, the moving slider, moving frame, mounting frame and positioning clamps are moved synchronously. The two sets of positioning clamps hold and fix the cable body. During the process, the cable body is clamped and fixed by the mutual approaching movement of two sets of mounting brackets. The return spring does not play a fixing role. The return spring is only to prevent the cable body from shaking and rubbing against the positioning clamp, and to prevent the positioning clamp from causing friction damage to the cable body during the fixing process. After the cable body is fixed, the tightening nut on the outer wall of the positioning screw is rotated to fix the first rotating wheel to one side of the fixing body. This prevents the first rotating wheel from rotating on its own when not in use, which would cause the cable body to loosen and increases the fixing stability of the cable body.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-4The device shown is a layered combing and fastening device for a special grade cable, including a fixing body 1. A first rotating wheel 2 is installed at one end of the fixing body 1. A handwheel 3 is installed at one end of the first rotating wheel 2. A connecting rod 4 is fixed at one end of the first rotating wheel 2. A double-acting screw 5 is installed at one end of the connecting rod 4. A screw nut 6 is sleeved on the outer wall of the double-acting screw 5. A movable slider 7 is fixed on the outer wall of the screw nut 6. A movable frame 8 is installed at the top of the movable slider 7. A mounting frame 9 is installed at one end of the movable frame 8. A return spring 10 is installed on the inner wall of the mounting frame 9. A positioning clamp 12 is installed at one end of the mounting frame 9. A positioning screw 14 is fixed on one side of the first rotating wheel 2.

[0030] When it is necessary to fix the cable body 18, the cable body 18 can be inserted between the two sets of positioning clamps 12 inside the fixing body 1. Then, by turning the first rotating wheel 2 with the handwheel 3, the first rotating wheel 2 drives the connecting rod 4 and the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 will drive the two sets of lead screw nuts 6 at both ends of the outer wall of the bidirectional lead screw 5 to move closer to each other in a straight line along the outer wall of the bidirectional lead screw 5. Under the action of the movement of the lead screw nuts 6, the moving slider 7, the moving frame 8, the mounting frame 9 and the positioning clamps 12 will move synchronously. The cable body 18 is clamped and fixed by the two sets of positioning clamps 12. During the process, the cable body 18 is clamped and fixed by the mutual approaching movement of the two sets of mounting brackets 9. The return spring 10 does not play a fixing role. The return spring 10 is only to prevent the cable body 18 from shaking and rubbing against the positioning clamp 12, so as to prevent the positioning clamp 12 from causing friction damage to the cable body 18 during the fixing process. After the cable body 18 is fixed, the tightening nut 15 on the outer wall of the positioning screw 14 is rotated so that the tightening nut 15 fixes the first rotating wheel 2 to one side of the fixing body 1, so as to prevent the first rotating wheel 2 from rotating when not in use, which would cause the fixing of the cable body 18 to loosen, thus increasing the fixing stability of the cable body 18.

[0031] The two ends of the return spring 10 are connected to the mounting plate 11.

[0032] The two ends of the reset spring 10 are fixed to the mounting bracket 9 and the positioning clamp 12 respectively by two sets of mounting plates 11. The reset spring 10 is only used to prevent the cable body 18 from shaking and to avoid friction between it and the positioning clamp 12, so as to prevent the positioning clamp 12 from causing damage to the cable body 18 during the process of fixing the cable body 18.

[0033] A limiting groove 13 is provided on one side of the main body 1 of the fixture.

[0034] When the first rotating wheel 2 is rotated, the positioning screw 14 will rotate along the inside of the limiting groove 13, and the rotation of the first rotating wheel 2 will be limited by the limiting groove 13 and the positioning screw 14.

[0035] The positioning screw 14 has a tightening nut 15 connected to its external thread.

[0036] Once the cable body 18 is fixed, the tightening nut 15 on the outer wall of the positioning screw 14 is rotated to fix the first rotating wheel 2 to one side of the fixture body 1, thus preventing the first rotating wheel 2 from rotating when not in use and causing the cable body 18 to loosen, thereby increasing the fixing stability of the cable body 18.

[0037] A second rotating wheel 16 is installed at the end of the fixture body 1 that is away from the first rotating wheel 2.

[0038] By installing a first rotating wheel 2 and a second rotating wheel 16 at both ends of the fixture body 1, the fixture body 1 can simultaneously fix two different cable bodies 18.

[0039] A limiting groove 17 is provided inside the main body 1 of the fixture.

[0040] When the movable frame 8 moves under the drive of the movable slider 7, it will move along the limiting groove 17. The limiting groove 17 limits the movement of the movable slider 7, thereby increasing the movement stability of the movable slider 7.

[0041] The positioning clamp 12 holds the cable body 18 on one side.

[0042] The cable body 18 is clamped by the mutual approach of two sets of positioning clamps 12.

[0043] Working principle: When using this special grade cable layer combing and fastening device, when it is necessary to fix the cable body 18, the cable body 18 can be inserted between the two sets of positioning clamps 12 inside the fixing body 1. Then, the first rotating wheel 2 is rotated by the handwheel 3, so that the first rotating wheel 2 drives the connecting rod 4 and the bidirectional screw 5 to rotate. The rotation of the bidirectional screw 5 will drive the two sets of screw nuts 6 at both ends of the outer wall of the bidirectional screw 5 to move closer to each other in a straight line along the outer wall of the bidirectional screw 5. Under the movement of the screw nuts 6, the moving slider 7, the moving frame 8, the mounting frame 9 and the positioning clamps 12 will move synchronously. The cable body 18 is clamped and fixed by the two sets of positioning clamps 12.

[0044] During the process of fixing the cable body 18, the cable body 18 is clamped and fixed by the mutual approaching movement of the two sets of mounting brackets 9. The return spring 10 does not play a fixing role. The return spring 10 is only to prevent the cable body 18 from shaking and rubbing against the positioning clamp 12, and to prevent the positioning clamp 12 from causing friction damage to the cable body 18 during the fixing process. After the cable body 18 is fixed, the tightening nut 15 on the outer wall of the positioning screw 14 is rotated so that the tightening nut 15 fixes the first rotating wheel 2 to one side of the fixing body 1, preventing the first rotating wheel 2 from rotating when not in use and causing the fixing of the cable body 18 to loosen, thus increasing the fixing stability of the cable body 18.

[0045] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
