Description

Technical Field

[0001] This utility model relates to the field of cable traction technology, and more specifically, to a convenient cable traction auxiliary device. Background Technology

[0002] In today's infrastructure construction and information and communication development, the demand for cable laying in industries such as power and communications continues to grow. Whether it's upgrading and transforming urban power grids, constructing large-scale 5G communication base stations, or laying power transmission lines in remote areas, efficient and reliable cable pulling operations are indispensable. Traditional cable pulling methods, such as relying solely on manual dragging, not only consume a lot of labor costs but are also extremely inefficient. Workers need to work at high intensity for long periods, which easily leads to fatigue, resulting in slow work progress and making it difficult to meet the strict time requirements of modern projects. Furthermore, manual pulling cannot precisely control the pulling force and speed of the cable. When the cable is dragged on the ground, it frequently rubs against the ground or other obstacles, easily causing wear and scratches on the cable sheath. This not only reduces the insulation performance of the cable but also shortens its service life. Therefore, cable pulling assistance is proposed to assist in cable laying.

[0003] For example, Chinese Patent CN221226980U discloses a cable traction auxiliary device, which includes a support frame, an electric motor mounted on the support frame, a rotating shaft fixedly connected to the output shaft of the electric motor, and a rotating shaft rotatably connected to the support frame at one end away from the electric motor. Support rods are fixedly connected to both sides of the rotating shaft, and a U-shaped soft pad for lapping the cable is provided at the end of the support rod away from the rotating shaft. As needed, at least two of these devices are placed parallel to each other on the line laying path, so that the rotating shaft is perpendicular to the line laying direction. Then, the casters are locked to prevent the devices from sliding. The cable is placed on the first or second soft pad between the first and second baffles, with the first or second soft pads of two adjacent devices arranged alternately (i.e., when the cable is placed on the first soft pad of the first device, the adjacent device is placed on the second soft pad). The first and second baffles prevent the cable from sliding out of the device during the laying process.

[0004] Considering that cable traction auxiliary devices generally use a motor to drive a turntable to move the cable during the cable laying process, but considering that the cable is generally long, during its transportation process, due to the long distance, the cable is very likely to fall onto the surface of the turntable used for laying. Once the cable falls onto the surface of the turntable, even if the motor is running at its maximum power, it is difficult to make the cable slide smoothly. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned shortcomings. Cable traction auxiliary devices often use a motor to drive a turntable to release the cable. However, the cable is usually long and is prone to falling onto the turntable surface due to the long distance during transport. Once this happens, even if the motor runs at full speed, it is difficult to make the cable slide smoothly.

[0006] To achieve the above objectives, this utility model provides a convenient cable traction auxiliary device, including a support frame body. A driving device is fixedly connected to the top of the support frame body, and a conveying component is provided at the output end of the driving device. Two sets of tension adjusting components are provided on the top of the support frame body, and the two sets of tension adjusting components are distributed at both ends of the conveying component, wherein:

[0007] The tension adjustment assembly includes a bracket fixedly connected to the top of the support frame body, a sliding groove is opened on the surface of the bracket, a sliding column is slidably connected to the inner wall of the sliding groove, and a small turntable is fixedly connected to the end of the sliding column;

[0008] During cable transport, the small turntable in the tension adjustment component at the output end slides within the groove of the bracket via a sliding column. It can adaptively adjust its position according to the real-time tension of the cable, thereby changing the tension on the cable and maintaining the cable tension within a suitable range. This prevents problems such as cable breakage, slackness, or knotting due to abnormal tension. The small turntable in the tension adjustment component at the input end rotates with the movement of the cable at the beginning of cable transport, assisting the cable to enter the transport component smoothly and steadily, reducing jamming and resistance at the start of cable transport. The small turntable at the output end also serves to guide the output cable, ensuring that the cable is output in the predetermined direction.

[0009] As a further improvement to this technical solution, the conveying assembly includes a large turntable rotatably connected to the output end of the drive device, and a plurality of limit frames are fixedly connected to the surface of the large turntable, with limit grooves formed on the surface of the limit frames.

[0010] The inner wall of the limiting groove is made of rubber to increase the friction with the cable surface;

[0011] The large turntable in the conveying assembly is rotatably connected to the output end of the drive device. When the drive device is working, it can drive the large turntable to rotate, and multiple limit frames fixed on the surface of the large turntable will rotate accordingly. The cable is placed in the limit groove on the surface of the limit frame. The rotation of multiple limit frames can drive the cable in the limit groove to slide synchronously, thereby realizing the conveying of the cable. The inner wall of the limit groove is made of rubber material. The good flexibility and high coefficient of friction of rubber increase the friction with the surface of the cable.

[0012] As a further improvement to this technical solution, a positioning wheel is fixedly connected to the end of the sliding column away from the small turntable, a positioning groove is opened on the surface of the bracket, a pin is inserted into the inner wall of the positioning groove, and a slot is opened on the surface of the positioning wheel, with the inner wall of the slot contacting the surface of the pin.

[0013] The support surface is provided with multiple positioning grooves, which are vertical and evenly distributed on the support surface with equal spacing.

[0014] After the sliding column moves the small turntable to the appropriate position, the pin is inserted into the positioning groove on the surface of the bracket, so that the pin is in close contact with the groove on the surface of the positioning wheel, thereby blocking the rotation of the positioning wheel and restricting the sliding of the sliding column, thus achieving the purpose of fixing the position of the small turntable. The bracket surface is provided with multiple vertically oriented and evenly distributed positioning grooves, so that no matter where the sliding column moves the small turntable in the groove, the positioning wheel connected to it can find the corresponding positioning groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this portable cable traction auxiliary device, tension adjustment components are set at both ends of the support frame. The small turntables in these components, in conjunction with the conveying components, avoid the slippage difficulties caused by cable drooping, ensuring that the cable can be effectively pulled. The cable is sequentially wrapped around the small turntables and the surface of the conveying components at both ends, forming a stable conveying path. The small turntable near the inlet end of the conveying components helps the cable smoothly enter the conveying components, while the small turntable at the outlet end guides and adjusts the tension to ensure that the cable is output in the predetermined direction, preventing twisting and tangling. The device maintains the stability and smoothness of the cable throughout the conveying process. When the cable accumulates due to delays in subsequent use, the sliding column can slide on the inner wall of the groove opened on the support surface, driving the small turntable to move its position. By adjusting the relative position of the small turntable and the cable, the cable conveying state is adaptively adjusted, effectively preventing problems such as tangling and knotting caused by excessive cable accumulation.

[0024] 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. Example

[0025] Please see Figures 1-3 As shown, this embodiment provides a convenient cable pulling auxiliary device, including a support frame body 1. A drive device 11 is fixedly connected to the top of the support frame body 1. A conveying component 2 is provided at the output end of the drive device 11. Two sets of tension adjusting components 3 are provided on the top of the support frame body 1, and the two sets of tension adjusting components 3 are distributed at both ends of the conveying component 2.

[0026] The tension adjustment assembly 3 includes a bracket 31 fixedly connected to the top of the support frame body 1. A groove 310 is opened on the surface of the bracket 31. A sliding column 320 is slidably connected to the inner wall of the groove 310. A small turntable 32 is fixedly connected to the end of the sliding column 320.

[0027] First, the cable is placed on the surface of the small turntable 32 at one end, then on the surface of the conveying assembly 2, and finally on the surface of the small turntable 32 at the other end. When the drive device 11 is started, the conveying assembly 2 rotates accordingly. During the rotation of the conveying assembly 2, the cable on its surface will slide due to friction. At the same time, the small turntable 32 near the cable inlet end of the conveying assembly 2 will rotate with the movement of the cable to assist in cable conveying. The small turntable 32 located at the cable outlet end plays a corresponding guiding and tension adjustment role for the conveyed cable, ensuring that the cable can be conveyed stably and smoothly. If, during the transport process, the cables accumulate due to delays in subsequent use stages, the sliding column 320 can be manually moved to slide along the inner wall of the groove 310 on the surface of the bracket 31. Since the end of the sliding column 320 is fixedly connected to the small turntable 32, the sliding of the sliding column 320 can drive the small turntable 32 to move. The change in the position of the small turntable 32 can adaptively adjust the transport status of the cables by adjusting its relative position to the cables when they are piled up, preventing problems such as tangling and knotting caused by excessive accumulation that affect normal transport.

[0028] The improvement in this embodiment is as follows:

[0029] Considering that cable traction auxiliary devices typically use a motor-driven turntable to move the cable during the cable laying process, but given the generally long length of the cable, it is prone to slumping onto the turntable surface due to the long distance involved in its transport. Once this happens, even with the motor running at maximum power, it is difficult for the cable to slide smoothly. Therefore, by using tension adjustment components 3 at both ends of the support frame body 1, with small turntables 32 working in conjunction with the conveying component 2, the sliding difficulties caused by cable slumping are avoided, ensuring that the cable can be effectively pulled. The cable is sequentially looped between the small turntables 32 and the conveying component 2 at both ends. On the surface, a stable conveying path is formed. The small turntable 32 near the inlet end of the conveying component 2 assists the cable to enter the conveying component 2 smoothly. The small turntable 32 at the outlet end guides and adjusts the tension to ensure that the cable is output in the predetermined direction, preventing twisting and tangling. It maintains the stability and smoothness of the cable throughout the conveying process. When the cable accumulates due to the lag in the progress of subsequent use, the sliding column 320 can slide on the inner wall of the sliding groove 310 opened on the surface of the bracket 31, driving the small turntable 32 to move its position. By adjusting the relative position relationship between the small turntable 32 and the cable, the cable conveying state is adaptively adjusted, effectively preventing the cable from tangling, knotting and other problems caused by excessive accumulation.

[0030] In order to enable the conveying assembly 2 to convey cables, the parts of the conveying assembly 2 need to be further disclosed. Therefore, the conveying assembly 2 includes a large turntable 21 rotatably connected to the output end of the drive device 11. Multiple limit frames 22 are fixedly connected to the surface of the large turntable 21. Limit grooves 220 are formed on the surface of the limit frames 22. By placing the cable in the limit grooves 220, when the drive device 11 drives the large turntable 21 to rotate, the multiple limit frames 22 can rotate simultaneously, so that the cable in the limit grooves 220 can slide accordingly.

[0031] To ensure that the cable in the limiting groove 220 can slide smoothly during the rotation of the limiting frame 22 without slipping and affecting cable transport, the inner wall of the limiting groove 220 is made of rubber to increase the friction with the cable surface. By placing rubber on the inner wall of the limiting groove 220, the good flexibility and high coefficient of friction of the rubber significantly increase the friction between the inner wall of the limiting groove 220 and the cable surface, which can firmly restrict the cable within the limiting groove 220 and effectively prevent the cable from slipping or displacing from the predetermined running track.

[0032] Considering that when the sliding column 320 slides on the inner wall of the slide groove 310 and drives the small turntable 32 to move, the first consideration is to fix the position of the small turntable 32. Therefore, a positioning wheel 33 is fixedly connected to the end of the sliding column 320 away from the small turntable 32. A positioning groove 311 is opened on the surface of the bracket 31, and a pin 34 is inserted into the inner wall of the positioning groove 311. A slot is opened on the surface of the positioning wheel 33, and the inner wall of the slot contacts the surface of the pin 34. By fixing the slot on the surface of the positioning wheel 33 and the positioning groove 311 on the surface of the bracket 31, the pin 34 is inserted into the positioning groove 311, so that the surface of the pin 34 is in close contact with the inner wall of the slot of the positioning wheel 33. At this time, the positioning wheel 33 is blocked by the pin 34 and cannot rotate freely, thereby restricting the sliding of the sliding column 320 and fixing the position of the small turntable 32. This ensures that in the subsequent cable conveying operation, the small turntable 32 can stably guide and adjust the tension of the cable.

[0033] In order for the pin 34 to position the positioning wheel 33 at different positions, multiple positioning grooves 311 are provided on the surface of the bracket 31. The positioning grooves 311 are vertical and evenly distributed on the surface of the bracket 31 at equal intervals. By providing multiple positioning grooves 311, the sliding column 320 can drive the small turntable 32 to slide in the sliding groove 310 to any position. The positioning wheel 33 connected to it can always correspond to the appropriate positioning groove 311. The operator can easily insert the pin 34 into the corresponding positioning groove 311, so that the pin 34 and the groove on the surface of the positioning wheel 33 are tightly fitted, thereby locking the positioning wheel 33 and stabilizing the position of the small turntable 32.

[0034] In practical use, this convenient cable traction auxiliary device first places the cable onto the surface of the small turntable 32 at one end, then places the cable in the limiting groove 220, and finally places it onto the surface of the small turntable 32 at the other end. When the drive device 11 is started, the large turntable 21 rotates accordingly, causing multiple limiting frames 22 to rotate simultaneously. The cable then slides in the limiting groove 220. At the same time, the small turntable 32 at the cable inlet end of the large turntable 21 rotates with the movement of the cable, assisting in cable delivery. The small turntable 32 at the cable outlet end, on the other hand, controls the cable delivery. The delivered cable serves as a guide and tension regulator. If the cable accumulates due to delays in subsequent use during the delivery process, the slide column 320 can be manually moved to slide along the inner wall of the groove 310 on the surface of the bracket 31. Since the end of the slide column 320 is fixedly connected to the small turntable 32, the sliding of the slide column 320 can drive the small turntable 32 to move. The change in the position of the small turntable 32 can adaptively adjust the delivery state of the cable by adjusting its relative position to the cable when the cable is accumulated.
