Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a cable installation traction frame. Background Technology

[0002] Publication No.: CN221380247U, Title: A Cable Laying Traction Frame, which discloses: including a bracket, with wheels fixedly installed on the surface of the bracket, and a connecting rod fixedly installed on the right side of the bracket, achieving better usage effect. When in use, the cable roll is first placed on the top of the support plate through the rotating block, and then the rotating block is pinched and pulled to the left, so that the rotating block rotates on the top of the support plate through the hinge. When the bottom end of the rotating block reaches the top of the support plate and the right side of the fixed plate is attached to the left side of the support plate, the pull handle can be pinched to push the corresponding sliding groove and fixed groove of the locking rod inward, so that the soft pad firmly locks the locking rod in the fixed groove. At this time, the rotating block can firmly lock the rotating block on the top of the support plate, thereby avoiding the situation where the cable roll falls off the support plate and causes cable damage due to excessive pulling force on the traction frame during use because the cable roll is not fixed.

[0003] The aforementioned disclosure can fix the cable reel. However, when releasing the cable from the reel, the weight of the reel is generally too large to be pulled out manually. A traction and pulling device needs to be set up outside the traction frame to effectively pull out the cable. As a result, multiple machines need to work together to achieve this during cable laying, which is quite cumbersome. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-6This utility model provides a technical solution: a cable installation traction frame, including a traction trolley 1, a placement frame 2 rotatably mounted on the upper surface of the traction trolley 1, a locking device 3 for fixing the position of the cable reel on the placement frame 2, and an external pulling device 6 fixedly mounted on the tail end of the placement frame 2 through a connecting frame 5. The external pulling device 6 is used to pull the cable out of the cable reel. The external pulling device 6 includes two rotating columns 61, the periphery of which is in contact with the outer sheath of the cable. A guide device 7 is provided on the upper surface of the connecting frame 5 between the traction trolley 1 and the external pulling device 6.

[0024] Specifically, the traction trolley 1 is existing technology and docks with the vehicle. When the vehicle starts, it drives the traction trolley 1 to move. The cable reel is fitted into the placement frame 2 on the traction trolley 1. The placement frame 2 rotates to release the cable. The locking device 3 can expand to abut against the inner wall of the cable reel, thereby fixing the position of the cable reel and preventing the cable reel from shifting when releasing the cable. The external pulling device 6 pulls the cable outward. In use, the rotating column 61 rotates and pulls the cable outward under the action of frictional resistance. The guiding device 7 guides the position of the cable so that the cable enters between the two rotating columns 61 at a specific angle.

[0025] The placement rack 2 includes a rotating plate 21. A first T-shaped ring block 22 is fixedly connected to the center of the bottom of the rotating plate 21. A first T-shaped ring groove 12 matching the first T-shaped ring block 22 is opened on the upper surface of the traction trolley 1. Multiple balls 23 are rolled and engaged on the lower surface of the rotating plate 21. A circular groove 11 cooperating with the balls 23 is opened on the upper surface of the traction trolley 1.

[0026] Specifically, the cable reel is placed on the rotating plate 21. The rotation of the rotating plate 21 drives the cable reel to rotate synchronously. The first T-shaped ring block 22 and the first T-shaped ring groove 12 rotatably connect the rotating plate 21 to the traction trolley 1. The setting of the ball bearing 23 can reduce the frictional resistance between the rotating plate 21 and the traction trolley 1 when the rotating plate 21 rotates.

[0027] A screw 43 is fixedly connected to the upper surface of the placement rack 2. An adjustment device 4 is provided around the screw 43. The adjustment device 4 includes a nut 41 that is threadedly connected to the screw 43. A lifting sleeve 42 is sleeved around the screw 43 and below the nut 41. Multiple sets of rotating rods 31 are provided between the lifting sleeve 42 and the placement rack 2. Each set of rotating rods 31 consists of two rods.

[0028] Specifically, the nut 41 rotates and moves downward under the action of the thread, which squeezes and drives the lifting sleeve 42 to move downward as well. The lifting sleeve 42 descends and drives the rotating rod 31 to rotate, so that the end of the rotating rod 31 squeezes and abuts against the cable reel, squeezing and fixing it.

[0029] One end of the two rotating rods 31 in a set is close to each other and rotates and is connected to each other. The other end of the two rotating rods 31 in a set is rotatably connected to the placement frame 2 and the lifting sleeve 42 respectively. The lower surface of the nut 41 is fixedly connected to the second T-shaped ring block 411. The upper surface of the lifting sleeve 42 is provided with a second T-shaped ring groove 421 that matches the second T-shaped ring block 411.

[0030] Specifically, the second T-shaped ring block 411 and the second T-shaped ring groove 421 cooperate with each other to rotatably connect the nut 41 and the lifting sleeve 42 together, so that the nut 41 can move up and down, which can drive the lifting sleeve 42 to move up and down synchronously.

[0031] The connecting frame 5 includes a connecting rod 52 fixedly connected to the traction trolley 1. A rectangular frame 51 is fixedly connected to the upper surface of the connecting rod 52. Two rotating columns 61 are vertically arranged inside the rectangular frame 51. The periphery of the rotating columns 61 is frosted. A third T-shaped ring block 611 is fixedly connected to both the upper and lower ends of the rotating columns 61. A third T-shaped ring groove 511 matching the third T-shaped ring block 611 is opened on the inner side of the rectangular frame 51.

[0032] Specifically, the third T-shaped ring block 611 and the third T-shaped ring groove 511 rotatably connect the rotating column 61 to the rectangular frame 51. The circumference of the rotating column 61 is set with a frosted surface, which can increase the friction between the rotating column 61 and the cable sheath, thereby effectively pulling out the cable.

[0033] A motor 62 is fixedly mounted on the connecting rod 52. The periphery of the third T-shaped ring block 611 located at the bottom of the two rotating columns 61 is fixedly connected with meshing ring teeth 612. The output shaft of the motor 62 is fixedly connected to one of the third T-shaped ring blocks 611.

[0034] Specifically, the motor 62 is existing technology and provides power for the rotation of the rotating column 61.

[0035] The guide device 7 includes a Y-shaped bracket 71 fixedly connected to the connecting frame 5, and a limit sleeve 72 is rotatably connected inside the Y-shaped bracket 71 via a rotating shaft.

[0036] Specifically, the cable passes through the limiting sleeve 72 and slides with it. The limiting sleeve 72 limits the height of the cable entering between the two rotating columns 61 to prevent the cable from tilting into the space between the two rotating columns 61 and reducing the traction efficiency.
