Description

Technical Field

[0001] This utility model relates to the field of communication construction, specifically a communication construction cable laying device. Background Technology

[0002] In communication construction and cable laying operations, track-type cable laying frames are commonly used cable laying equipment. When adjusting the pulley spacing of existing track-type cable laying frames, the adjusting nut and groove are generally used for locking.

[0003] On the one hand, the process of loosening and tightening the nut is quite cumbersome; on the other hand, in the actual cable laying operation, due to the continuous vibration generated during cable laying, the frequent changes in cable tension, and the dynamic impact when the reel rotates, the locking structure composed of the nut and the groove is very prone to loosening. Once the nut is loose, the pulley loses its effective constraint and there is a risk of displacement. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this utility model is to provide a communication construction cable laying device to solve the problems mentioned in the background art, such as the cumbersome installation of pulleys and the risk of displacement of conventional cable laying frames.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a communication construction and cable laying device, comprising a pair of support frames and a positioning rod, wherein two pulleys are detachably mounted on the positioning rod and rotatably mounted via a rotating shaft, and the top of the support frame is provided with a plurality of grooves for accommodating the rotating shaft, wherein one of the pulleys is locked in the groove by a nut, and the other pulley is engaged in the groove by an elastic member to prevent the pulley from dislodging from the groove.

[0006] Preferably, one end of the support frame is provided with an inclined structure.

[0007] Preferably, a pad is movably mounted on the bottom of the support frame, and the elastic member is a pair of tension springs respectively sleeved on both ends of the rotating shaft, with the other end of the tension spring connected to the pad.

[0008] Preferably, the support frame has concave sections on both sides for accommodating the pad.

[0009] Preferably, the pad has a U-shaped structure, and both ends of the pad are respectively provided with through holes for hooking the tension spring.

[0010] Preferably, the side wall of the support frame is provided with a circular hole for the positioning rod to pass through.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a tension spring and a pad to constrain the pulley in a groove. The continuous and adaptive tension of the tension spring keeps the pulley firmly fixed in the groove, which can effectively cope with complex working conditions such as different wire feeding speeds, spool weights, and unexpected disturbances, and also facilitates the adjustment of the distance between a pair of pulleys.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a communication construction cable laying device, including a pair of support frames 1 and a positioning rod 2. The side wall of the support frame 1 is provided with a round hole for the positioning rod 2 to pass through. The pair of support frames 1 are connected through the positioning rod 2 to keep them parallel. One end of the support frame 1 is provided with an inclined structure 5. The inclined structure 5 is conducive to rolling the cable reel to the top of the support frame 1. Two pulleys 4 are detachably mounted on the positioning rod 2 and are rotatably mounted on the shaft 3. The top of the support frame 1 is provided with several grooves 8 for accommodating the shaft 3. Nuts are threaded on both ends of the shaft 3. One pulley 4 is locked in the groove 8 by the nut, and the other pulley 4 is engaged in the groove 8 by an elastic member to prevent the pulley 4 from dislodging from the groove 8. A pad 7 is movably installed at the bottom of the support frame 1. The two sides of the support frame 1 are respectively provided with concave sections 9 for accommodating the pad 7. The concave sections 9 provide sliding space for the pad 7 and do not affect the horizontal placement of the support frame 1. The elastic component is a pair of tension springs 6 respectively sleeved on both ends of the rotating shaft 3. The other end of the tension spring 6 is connected to the pad 7. The pad 7 has a U-shaped structure. The horizontal section of the U-shaped structure is adapted to the width of the support frame 1. Both ends of the pad 7 are respectively provided with through holes 10 for hooking the tension spring 6. The two ends of the tension spring 6 are hooked on the rotating shaft 3 and the pad 7 respectively.

[0020] When it is necessary to adjust the spacing of a pair of pulleys 4 according to the spool, pulleys 4 are pulled up until the shaft 3 is disengaged from the groove 8. The shaft 3 is then slid on the top of the support frame 1 to the designated groove 8 and then the pulleys 4 are released. The tension spring 6 uses its own elastic potential energy to constrain the shaft 3 to be stably fixed in the groove 8. Compared with the current method of adjusting the position of pulleys 4 by turning bolts, the structure is simple and the operation is convenient, bringing convenience to the quick adjustment of the position of pulleys 4.

[0021] During the wire feeding process, the rotation of the spool may cause slight wobble and positional changes in the pulley 4. In this device, the tension spring 6 can always maintain the constraint on the pulley 4 to adapt to different wire feeding speeds, spool weights, and possible unexpected disturbances, greatly reducing the risk of the pulley 4 dislodging from the groove 8 and improving the reliability of the wire feeding frame.
