[0002] After the cable is produced, the cable will be evenly wound around the outer ring of the cable reel for storage and transportation. In the prior art, traditional cable reels generally lack a dedicated braking device. Most on-site workers use steel pipes or wooden sticks to apply brute force for braking, and the braking effect is not obvious and there are great potential safety hazards.

[0003] How to solve the above technical problems has become an urgent problem to be solved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable reel braking device, aiming to solve the problems pointed out in the background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A cable reel braking device includes a cable reel body: used for winding the cable; two braking parts: respectively arranged at the left and right ends of the cable reel body, and the braking parts can clamp the ends of the cable reel body, so as to control the rotation speed of the cable reel body, and then brake the cable reel body; the braking part includes two symmetrically arranged friction wheels, and the two friction wheels can move towards or away from each other. When the two friction wheels move towards each other, they can clamp the cable reel body, so that it can be applicable to cable reel bodies with different diameters for clamping. And the two friction wheels can rotate in the direction opposite to the rotation direction of the cable reel body, and brake through the frictional force between the friction wheels and the cable reel body; the braking part also includes a driving part. When the friction wheels clamp the cable reel body, the rotation of the cable reel body can drive the friction wheels to rotate in the reverse direction. The driving part includes a connecting mechanism for detachably connecting the cable reel body and the driving part.

[0007] A further technical scheme of the utility model is that the driving part further includes a slide rail arranged at the end of the cable reel body. Two sliders are slidably connected in the slide rail. A rotating shaft is rotatably connected in each of the two sliders, and one end of the rotating shaft close to the friction wheel is fixedly connected to the friction wheel. A fixed block is fixedly connected in the slide rail. A large gear is arranged on the side of the fixed block away from the cable reel body. When the cable reel body rotates, it can drive the large gear to rotate through the connecting mechanism. One end of the rotating shaft away from the friction wheel is fixedly connected to a small gear. When the friction wheels clamp the cable reel body, the small gear can mesh with the large gear.

[0008] A further technical solution of the present utility model is that the connecting mechanism includes a rotating shaft rotatably connected within the fixed block. One end of the rotating shaft close to the large gear is fixedly connected to the large gear. A non-circular groove is provided at one end of the rotating shaft close to the cable reel body. One side of the cable reel body close to the rotating shaft is fixedly connected with a non-circular rod adapted to the non-circular groove. When the fixed block approaches the cable reel body, the non-circular rod can be inserted into the non-circular groove.

[0009] A further technical solution of the present utility model is that a driving positioning part is provided on the slide rail for driving the two small gears and the friction wheels to move, so that the small gears are engaged with the large gear and the friction wheels clamp the cable reel body.

[0010] A further technical solution of the present utility model is that the driving positioning part includes two nuts, and the two nuts are respectively rotatably connected to one side of the two small gears away from the cable reel body. A screw rod is threadedly connected within the two nuts, and one end of the screw rod is fixedly connected with a turning handle.

[0011] A further technical solution of the present utility model is that a fixing frame is provided below the slide rail, and the slide rail is fixed to the fixing frame, and the fixing frame is fixed to the ground.

[0012] The beneficial effects of the present utility model are as follows:

[0013] During use, the cable reel body is detachably connected to the driving part through the connecting mechanism, and then the two friction wheels are driven to move towards each other to clamp the cable reel body. When the cable reel body rotates, it can drive the driving part to work through the connecting mechanism. When the driving part works, it can drive the two friction wheels to rotate in the opposite direction relative to the cable reel body, and brake the cable reel body through the rotational friction force between the friction wheels and the cable reel body, thereby effectively reducing potential safety hazards.

[0018] The specific implementation manner of the present utility model will be further described below in conjunction with the accompanying drawings.

[0019] As Figures 1-3 shown, a cable reel braking device includes a cable reel body 1 for winding the cable. Braking parts are arranged at both the left and right ends of the cable reel body 1. When the cable reel body 1 rotates to pay out the cable, the braking parts can clamp the ends of the cable reel body 1, thereby controlling the rotation speed of the cable reel body 1 and further braking the cable reel body 1. The braking parts include two symmetrically arranged friction wheels 23, and the two friction wheels 23 can move towards or away from each other. When braking is required, driving the two friction wheels 23 to move towards each other can clamp the cable reel body 1, so that it can be applicable to cable reel bodies 1 with different diameters for clamping, improving the practicability of the braking parts. Moreover, the two friction wheels 23 can rotate in a direction opposite to the rotation direction of the cable reel body 1, so as to brake through the frictional force between the friction wheels 23 and the cable reel body 1. The braking parts further include a driving part. When the friction wheels 23 clamp the cable reel body 1, the rotation of the cable reel body 1 can drive the friction wheels 23 to rotate in the reverse direction.

[0020] As Figures 1-3As shown in the figure, the driving part includes a slide rail 21 arranged at the end of the cable reel body 1. Two sliders 22 are slidably connected in the slide rail 21. A rotating shaft is rotatably connected in each of the two sliders 22. One end of the rotating shaft close to the friction wheel 23 is fixedly connected to the friction wheel 23. A fixed block 24 is fixedly connected in the slide rail 21. A connecting mechanism is arranged in the fixed block 24. The cable reel body 1 and the fixed block 24 are detachably connected through the connecting mechanism. A large gear 25 is arranged on one side of the fixed block 24 away from the cable reel body 1. When the cable reel body 1 rotates, the large gear 25 can be driven to rotate through the connecting mechanism. One end of the rotating shaft away from the friction wheel 23 is fixedly connected to a small gear 26. When the friction wheel 23 clamps the cable reel body 1, the small gear 26 can mesh with the large gear 25. When the cable reel body 1 rotates, the large gear 25 can be driven to rotate through the connecting mechanism. Then, the rotation of the large gear 25 can drive the small gear 26 to reverse. Then, the rotation of the small gear 26 can drive the friction wheel 23 to rotate through the rotating shaft, so as to brake the cable reel body 1 through the rotational friction force between the cable reel body 1 and the friction wheel 23. A driving positioning part is arranged on the slide rail 21, which is used to drive the two small gears 26 and the friction wheel 23 to move, so that the small gear 26 meshes with the large gear 25 and the friction wheel 23 clamps the cable reel body 1;

[0021] The connecting mechanism includes a rotating shaft 27 rotatably connected in the fixed block 24. One end of the rotating shaft 27 close to the large gear 25 is fixedly connected to the large gear 25. A non-circular groove 28 is opened at one end of the rotating shaft 27 close to the cable reel body 1. A non-circular rod 29 adapted to the non-circular groove 28 is fixedly connected to one side of the cable reel body 1 close to the rotating shaft 27. When the fixed block 24 approaches the cable reel body 1, the non-circular rod 29 can be inserted into the non-circular groove 28. When the cable reel body 1 rotates, the non-circular rod 29 can be driven to rotate. Then, the rotation of the non-circular rod 29 can drive the rotating shaft 27 to rotate through the non-circular groove 28. When the rotating shaft 27 rotates, the large gear 25 can be driven to rotate. Thus, it can be realized that when the cable reel body 1 rotates, the large gear 25 can be driven to rotate, and the cable reel body 1 and the braking part can be disassembled and separated, which is convenient for storage when not in use.

[0022] As Figure 1 and Figure 2As shown in the figure, the driving and positioning part includes two nuts 31, and the two nuts 31 are respectively rotatably connected to one side of the two pinions 26 away from the cable reel body 1. A screw rod 32 is threadedly connected inside the two nuts 31. One end of the screw rod 32 is fixedly connected to a torsion 33. When the driving torsion 33 rotates, it can drive the screw rod 32 to rotate. Then, when the screw rod 32 rotates, it can drive the two nuts 31 to move towards or away from each other. When the nuts 31 move, they can drive the pinions 26 to move. When the two pinions 26 move towards each other, they can be engaged with the large gear 25. When the pinions 26 move, they can drive the two friction wheels 23 to move. Thus, the two friction wheels 23 can clamp the cable reel body 1, and then the two friction wheels 23 and the pinions 26 can be driven to translate.

[0023] As Figure 1 and Figure 2 As shown in the figure, a fixing frame 4 is arranged below the slide rail 21, and the slide rail 21 is fixed to the fixing frame 4 to install and fix the slide rail 21. The fixing frame 4 is fixed to the ground to prevent the fixing frame 4 from moving under the reaction force of the cable reel body 1 when braking the cable reel body 1.

[0024] Working principle: First, insert the non-circular rod 29 into the non-circular groove 28, then fix the fixing frame 4 to the ground, and then drive the driving and positioning part to clamp the end of the cable reel body 1 with the friction wheels 23. At this time, the driving and positioning part can also drive the pinions 26 to be engaged with the large gear 25. After installation, when the cable reel body 1 rotates, it can drive the large gear 25 to rotate through the connecting mechanism. The rotation of the large gear 25 can drive the pinions 26 to reverse. Then, the reverse rotation of the pinions 26 can drive the friction wheels 23 to reverse. Through the rotational friction force between the friction wheels 23 and the cable reel body 1, the cable reel body 1 is braked, thereby effectively reducing potential safety hazards. Moreover, when not in use, the cable reel body 1 and the braking part can be separated, which is convenient for the user to carry and store.
