[0002] A cable is a device for transmitting electrical energy or signals. It is usually made up of several or several groups of conductors (at least two in each group) twisted together. Each group of conductors is insulated from each other and wrapped with a highly insulating covering. Cables are often installed in the air or underground or underwater, and are mainly used for telecommunications or power transmission. During the laying process of cables, traction equipment is required to pull and transport the cables, thereby greatly reducing the labor intensity of workers and improving the quality of construction.

[0003] Some existing cable pulling devices, which are mostly made of wire, can damage the cable's exterior. The wire puller can scratch the cable's insulation when pulling. These scratches can expose the internal conductor, increasing the risk of cable damage. Uneven pressure from the wire during pulling can cause indentations or depressions on the cable surface, potentially leading to future failures. A cable pulling device for cable laying has been proposed to address these issues. Utility Model Content

The right side of the limiting column 15 is slidably connected to the left side of the rotating disk 14 to ensure that the position and tension of the cable 3 can be stably controlled during the traction process of the cable 3.

[0034] The right sides of the multiple limiting columns 15 are all slidably connected to the left side of the rotating disk 14, and the rotation of the rotating disk 14 can adjust the tension and position of the limiting columns 15. Wheels 18 are fixedly connected to the bottom of the base plate 1 on all four sides. The wheels 18 allow the traction device to be easily moved between different work sites. The design of the wheels 18 takes into account the load capacity and ground adaptability to ensure smooth operation in various working environments. The left sides of the multiple limiting columns 15 are all slidably connected to the inside of the shell 12, and a slide groove is provided on one side of the rotating disk 14. This allows the limiting columns 15 to maintain good centering and tension adjustment during the limiting process. The left side of the limiting column 15 is slidably connected to the rotating disk 14, and a handle 13 is fixedly connected to one side of the rotating disk 14. The outer side of the handle 13 is slidably connected to the shell 12. The design of the shell 12 protects the internal components and provides an operating interface for the device.

[0035] A traction ring 17 is fixedly connected to the right side of the housing 12, and a restraining assembly for restraining an object is fixedly connected to the front end of the base plate 1. The traction assembly includes a traction wheel 10, the outer side of which is rotatably connected to the inner side of the cable 3. The front end of the traction wheel 10 is fixedly connected to a motor 11. The traction assembly is designed to provide stable and adjustable traction to meet the traction requirements of different objects. The power and control system of the motor 11 can be adjusted according to the actual application requirements to improve traction efficiency and control accuracy.

[0036] Reference Figure 2 、 Figure 3 The limiting assembly includes a protective shell 4, one side of which is fixedly connected to the front end of the base plate 1. A plurality of springs 5 ​​are fixedly mounted inside the protective shell 4. Each of the springs 5 ​​is fixedly connected to an inclined block 6 at one end. One side of the inclined blocks 6 is set at an angle, and one side of the long plate 8 is set at an angle. Multiple springs 5 ​​and inclined blocks 6 are installed inside the protective shell 4. The protective shell 4 is designed to protect the other components of the device from the external environment. Elastic support is provided to cope with dynamic changes during traction. The angled design optimizes the stability of the device and the traction effect.

[0037] The adjacent sides of the multiple inclined blocks 6 are all slidably connected to the disc 7, and the right side of the disc 7 is rotatably connected to the long plate 8, providing further stability and rotation support. The rear end of the long plate 8 is fixedly connected to the rotating shaft, and the other side of the rotating shaft is fixedly connected to the inside of the drum 2. The other side of the rotating shaft is fixedly connected to the inside of the drum 2 for supporting and transmitting rotational power. The right side of the long plate 8 is fixedly connected to the spring 2 9, and one end of the spring 2 9 is fixedly connected to the rear end of the disc 7. The spring 2 9 is used to provide additional elastic support to ensure that the long plate 8 and the disc 7 can operate stably during the traction process and absorb vibration and impact.

[0038] Working principle: After the staff wraps the cable 3 around the outside of the traction wheel 10, they can start the motor 11, so that the motor 11 drives the traction wheel 10, and the other end of the cable 3 is placed inside the shell 12. Then, the staff can manually pull the handle 13 to drive the rotating disk 14 inside it. A sliding groove is provided on one side of the rotating disk 14, and a limiting column 15 is slidably connected to the inside of the sliding groove, and a splint 16 is fixedly connected to the outside of the limiting column 15. One end of the splint 16 slides in the sliding groove of the rotating disk 14, and the other end slides on one side of the shell 12, and the outside There is also a slide groove on one side of the shell 12, so when the staff pulls the handle 13, they can drive the internal rotating disk 14, and drive multiple limiting columns 15 through the slide groove on one side of the rotating disk 14, so that multiple clamping plates 16 can be adjusted to clamp the cable 3 inside the shell 12. The traction wheel 10 drives one end of the cable 3, and the other end of the cable 3 is wound around the outside of the drum 2. At this time, the protective shell 4 fixed to one side of the bottom plate 1 can be used. The inside of the protective shell 4 is provided with a disc 7, and one side of the disc 7 is rotatably connected to a long The plate 8 is provided with a plurality of springs 5 ​​and inclined blocks 6 inside the protective shell 4, and the interior of the long plate 8 is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to the inside of the drum 2, so when the drum 2 rotates, it will also drive the long plate 8, and the long plate 8 will drive the disc 7 through the spring 2 9, because there is a notch on one side of the disc 7 and this notch will be restricted by the inclined block 6, because one end of the inclined block 6 is set at an angle to fit the notch on one side of the disc 7, and the other side is fixedly connected to the spring 5, and when the inclined block 6 does not encounter the notch, it will be due to the external air The space is not enough, so the spring 1 5 is squeezed inwardly, and when it encounters a gap, it will be ejected by the spring 1 5, so as to use the gap to clamp the disc 7. At this time, when the long board 8 rotates to the clamping position, one end of the long board 8 is also set at an angle, so the spring 1 5 can be pushed back to the used position through this angle. At this time, the disc 7 will be pulled by the spring 2 9 to the next spring 1 5 because there is no restriction. In this way, the rotation of the drum 2 can be restricted to avoid the cable 3 being pulled too long due to excessive speed and having to be rewound back.
