Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying traction head anti-drop locking mechanism. Background Technology

[0002] A cable laying pull head is an auxiliary tool used to pull cables. It is mainly used to pull cables during the cable laying process to ensure that the cables are laid along the predetermined path.

[0003] When existing cable laying traction heads pull cables, due to the weight of the cables, after a long period of pulling, the traditional traction head will gradually separate from the cable and eventually fall off. This not only causes wear on the outer wall of the cable, but also affects the normal cable laying operation. In order to solve the above problems and defects, there is an urgent need for a cable laying traction head anti-fall-off locking mechanism. Utility Model Content

Detailed Implementation

[0030] The following is a detailed description of a cable laying traction head anti-drop locking mechanism provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of this utility model provides a cable laying traction head anti-drop locking mechanism, including: a fixed shaft 1, a locking assembly 2 on one side of the fixed shaft 1, and a traction assembly 3 on the other side of the fixed shaft 1; the locking assembly 2 includes a fixed tube 21 installed on the side wall of the fixed shaft 1, an inclined groove is formed on the side of the fixed tube 21 away from the fixed shaft 1, a groove 22 is formed on the outer wall of the fixed tube 21, a square groove 23 is formed on the inner wall of the fixed tube 21, a spring 24 providing elastic force is fixedly mounted on the inner wall of the groove 22, a movable plate 25 is fixedly mounted on the top of the spring 24, and the movable plate 25 is close to the spring 24. A movable rod 26 is fixedly mounted on one side, the movable rod 26 passes through the fixed tube 21, and a clamping plate 27 is fixedly mounted at the end of the movable rod 26. A fixing ring 28 is threadedly connected to the outer wall of the fixed shaft 1. The number of springs 24, movable plates 25, movable rods 26 and clamping plates 27 are several sets, and there are at least eight sets of springs 24, movable plates 25, movable rods 26 and clamping plates 27 evenly distributed around the periphery of the fixed tube 21. By limiting the number and position of springs 24, movable plates 25, movable rods 26 and clamping plates 27, it is beneficial to improve the fixing effect of the cable, thereby preventing the cable from falling off during operation.

[0032] like Figure 1 and Figure 2 As shown, the traction assembly 3 includes a connecting shaft 31 installed on the side of the fixed shaft 1 away from the fixed tube 21. A traction shaft 32 is rotatably connected to the outer wall of the connecting shaft 31. A traction ring 33 is fixedly assembled on the side of the traction shaft 32 away from the connecting shaft 31. By setting the connecting shaft 31, the traction shaft 32 and the traction ring 33, the traction device can be used to pull the device and the cable through the traction ring 33. When the cable is twisted, the fixed tube 21 and the connecting shaft 31 can be rotated to restore the state of the cable, which facilitates the pulling of the cable.

[0033] like Figure 1 and Figure 2 As shown, the cross-sectional shape of the movable plate 25 is a right trapezoid, and the hypotenuse of the movable plate 25 is located on the side close to the fixing ring 28. By limiting the movable plate 25, it is beneficial for the fixing tube 21 and the movable plate 25 to be squeezed, thereby forcing the movable plate 25 to move deeper into the groove 22.

[0034] like Figure 2 and Figure 4 As shown, a baffle 2501 is fixedly mounted on the side of the movable plate 25 away from the spring 24. The baffle 2501 is located on the side away from the fixed ring 28. By setting the baffle 2501, it is beneficial to limit the fixed ring 28 and prevent the fixed ring 28 from separating from the device.

[0035] like Figure 2 and Figure 4As shown, a sliding block 2701 is fixedly mounted on the side of the clamping plate 27 away from the moving rod 26. The outer wall of the sliding block 2701 is covered with a rubber pad. By setting the sliding block 2701, the friction between the clamping plate 27 and the outer wall of the cable is improved, thereby improving the fixing effect of the cable.

[0036] like Figure 2 and Figure 3 As shown, the outer wall of the fixing ring 28 is provided with anti-slip strips 2801, and the side of the fixing ring 28 near the moving plate 25 is provided with a guide groove 2802. By setting the anti-slip strips 2801, the friction between the worker's palm and the outer wall of the fixing ring 28 is improved. By setting the guide groove 2802, the smoothness of the fixing ring 28 moving to the outer wall of the moving plate 25 is improved, thereby facilitating the fixing effect of the cable.

[0037] The technical solution provided by this utility model, during operation, involves inserting the cable into the fixed tube 21, then rotating the fixed ring 28, which moves towards the moving plate 25. The fixed ring 28 presses against the moving plate 25, causing the moving plate 25 to push the moving rod 26 and the clamping plate 27 towards the center of the fixed tube 21. With the cooperation of several sets of clamping plates 27, the cable is clamped and fixed, thereby improving the fixing effect of the cable. When the operation is completed, it is only necessary to rotate the fixed ring 28 in the opposite direction to separate the fixed ring 28 from the moving plate 25. At this time, the spring 24 pushes the moving plate 25 to move away from the groove 22, causing the clamping plate 27 to separate from the cable, and then the cable can be taken out from the fixed tube 21.

[0038] By setting up a connecting shaft 31, a traction shaft 32, and a traction ring 33, the device and the cable can be pulled by a traction device through the traction ring 33. When the cable is twisted, the fixed tube 21 and the connecting shaft 31 can be rotated to restore the state of the cable, making it easier to pull the cable.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
