Description

Technical Field

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

[0002] Cable laying is a complex and challenging task in power engineering construction, especially in special environments such as underground, underwater, or underground tunnels. These environments share common characteristics: confined space, insufficient light, high humidity, and potential additional challenges such as water or soil pressure, all of which significantly increase the difficulty of cable laying. Cables are not only heavy, but to ensure the safety and stability of power transmission, they are typically wrapped with one or more layers of thick insulation material. This not only increases the cable's weight but also makes its surface exceptionally smooth, making it difficult to grasp or drag by hand.

[0003] Chinese Patent 202121405216.8 discloses a high-efficiency installation and traction device for power cables, which includes a conveying wheel, a drive unit, a transmission mechanism, and a clamping mechanism. Rotating a rotating block drives a worm gear, which in turn drives a worm wheel via a connecting rod. This causes a gear rack to move vertically, which in turn moves a roller to clamp and fix the cable. Starting a motor then rotates the conveying wheel, thus enabling the cable to be conveyed. However, in use, clamping the cable still requires manual rotation of the rotating block, and the clamping and conveying operations are performed separately. The motor can only be started to convey the cable after it is clamped in place, resulting in low automation and low laying efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a cable traction device that can solve the problem of low automation in existing traction equipment, which leads to low laying efficiency.

The guide groove includes two oppositely arranged first arc-shaped guide sections and two oppositely arranged second arc-shaped guide sections. The two first arc-shaped guide sections protrude to the side away from each other, and the two second arc-shaped guide sections protrude to the side away from each other. The diameter of the circle containing the two first arc-shaped guide sections is smaller than the diameter of the circle containing the two second arc-shaped guide sections. The two first arc-shaped guide sections and the two second arc-shaped guide sections are alternately arranged and connected in sequence along the circumference of the first gear. When the second end of the connector is located on the first arc-shaped guide section, the clamping part is in a clamped state. When the second end of the connector is located on the second arc-shaped guide section, the clamping part is in a released state.

[0010] Furthermore, the guide groove also includes two first transition sections and two second transition sections. One of the first arc-shaped guide sections has a first transition section at each end, and the other first arc-shaped guide section has a second transition section at each end. The first ends of both first transition sections are connected to the corresponding first arc-shaped guide sections. The second end of one of the first transition sections is connected to the first end of one of the second arc-shaped guide sections, and the second end of the other first transition section is connected to the first end of the other second arc-shaped guide section. The first ends of both second transition sections are connected to the corresponding first arc-shaped guide sections. The second end of one of the second transition sections is connected to the second end of one of the second arc-shaped guide sections, and the second end of the other second transition section is connected to the second end of the other second arc-shaped guide section.

[0011] Furthermore, the drive unit includes a motor and a rack, the output shaft of the motor is driven to connect with the rack, the transmission unit includes a rotating member and a second gear mounted on the rotating member, the rack and the rotating member are spaced apart, the second gear meshes with the rack, both the rack and the rotating member are configured to pass through the moving part, and the outer wall surface of the rotating member drives to engage with the moving part.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1 to 4 As shown, this utility model provides a cable pulling device, which includes: a mounting base 10; a clamping mechanism 20, the clamping mechanism 20 including a clamping part 21 and a moving part 22, the clamping part 21 being mounted on the moving part 22, the clamping part 21 having a clamping state for clamping the cable and a releasing state for releasing the cable, the moving part 22 being movably disposed relative to the mounting base 10 along a first direction; and a first driving mechanism 30, mounted on the mounting base 10, the first driving mechanism 30 being capable of driving the clamping mechanism 20 to switch between the clamping state and the releasing state and driving the moving part 22 to move relative to the mounting base 10 along the first direction.

[0026] In this embodiment, the first direction refers to the cable conveying direction. Because the clamping part 21 has clamping and releasing functions, and the moving part 22 has a movable design, this cable pulling device can be applied to various cable construction scenarios, whether indoors or outdoors, on the ground or underground, for cable laying work. By automating the clamping, releasing, and moving functions, it facilitates automatic cable dragging during construction operations, reducing the labor intensity of workers, significantly reducing reliance on manual labor, lowering construction costs, and also reducing the risk of accidents caused by improper manual operation.

[0027] When laying cables, the first drive mechanism 30 drives the clamping mechanism 20 to clamp the cable. Then, the moving part 22 moves relative to the mounting base 10 in the first direction under the drive of the first drive mechanism 30 to transport the cable to the designated position. This can avoid the inconvenience and safety hazards caused by manual operation, and also improve the efficiency of cable laying.

[0028] See also Figures 1 to 4 As shown, in one embodiment of the present invention, the first driving mechanism 30 includes a driving part 31 and a transmission part 32. The driving part 31 drives and cooperates with the clamping part 21 to switch the clamping mechanism 20 between a clamping state and a releasing state. The driving part 31 drives and cooperates with the transmission part 32 to make the moving part 22 reciprocate linearly relative to the mounting base 10 in a first direction.

[0029] In this embodiment, the drive unit 31 directly cooperates with the clamping unit 21 to switch the clamping mechanism 20 between the clamping state and the releasing state. This automated operation greatly improves construction efficiency and avoids the problems of excessive waiting time and discontinuous operation caused by manual operation. The cooperation between the drive unit 31 and the transmission unit 32 enables the moving unit 22 to perform reciprocating linear motion along the first direction, ensuring that the cable is arranged according to the predetermined path and requirements during construction.

[0030] See also Figures 1 to 4 As shown, in one embodiment of the present invention, the clamping part 21 includes a second driving mechanism 211 and two grippers 212 rotatably disposed on the moving part 22 at intervals along a second direction. The second driving mechanism 211 is connected between the two grippers 212. The second driving mechanism 211 is rotatably engaged with the driving part 31 and, under the drive of the driving part 31, causes the clamping ends 214 of the two grippers 212 to move toward or away from each other.

[0031] In this embodiment, driven by the drive unit 31, and through the cooperation of the drive unit 31 and the second drive mechanism 211, the clamping ends 214 of the two grippers 212 can move closer to or further away from each other, thus enabling the clamping mechanism 20 to switch between a clamping state and a releasing state. The two grippers 212 are independently arranged and can rotate relative to the moving part 22 to accommodate cables of different diameters, improving the applicability of the cable pulling device.

[0032] See also Figures 1 to 4As shown, in one embodiment of the present invention, the second drive mechanism 211 includes a first gear 2111 and two connecting members 2112. The first gear 2111 is rotatably disposed relative to the mounting base 10. The two connecting members 2112 are disposed in one-to-one correspondence with the two grippers 212. The first end of the connecting member 2112 is hinged to the corresponding gripper 212, and the second end of the connecting member 2112 is connected to the first gear 2111. Under the drive of the first gear 2111, the clamping part 21 can switch between a clamping state and a releasing state. The drive unit 31 includes a motor 311 and a rack 312. The output shaft of the motor 311 is drivenly connected to the rack 312. The transmission unit 32 includes a rotating member 321 and a second gear 322 mounted on the rotating member 321. The rack 312 and the rotating member 321 are spaced apart. The second gear 322 meshes with the rack 312. Both the rack 312 and the rotating member 321 are configured to pass through the moving part 22. The outer wall surface of the rotating member 321 is drivenly engaged with the moving part 22.

[0033] In this embodiment, the outer peripheral surface of the rack 312 is provided with teeth that can mesh with the first gear 2111. The output shaft of the motor 311 drives the rack 312 to rotate. The rotation of the rack 312 is transmitted to the rotating member 321 through the second gear 322 that meshes with it, causing the rotating member 321 to also start rotating. The specific driving engagement mechanism between the outer wall surface of the rotating member 321 and the moving part 22 causes the moving part 22 to reciprocate linearly along the first direction. At the same time, the rack 312 meshes with the first gear 2111, driving the first gear 2111 to rotate. The rotation of the first gear 2111 is transmitted to the two grippers 212 through two connectors 2112. The first end of each connector 2112 is hinged to a gripper 212, and the second end is connected to the first gear 2111. As the first gear 2111 rotates, the second end of the connector 2112 causes the gripping ends 214 of the two grippers 212 to move closer to or further away from each other, realizing the automatic switching of the gripping part 21 between the clamping state and the releasing state. With the above settings, the automatic clamping, dragging and releasing operation of the cable can be realized.

[0034] See also Figures 1 to 3 As shown, in one embodiment of the present invention, both grippers 212 are provided with elongated holes 213, which extend toward the gripping end 214. The first end of the connector 2112 can slide relative to the elongated hole 213 along the extension direction of the elongated hole 213.

[0035] See also Figures 1 to 3As shown, in one embodiment of the present invention, the movable part 22 further includes a connecting block 224 and a movable block 225. The connecting block 224 is fixedly disposed on the top of the movable block 225, and two grippers 212 are rotatably disposed on the connecting block 224. The movable block 225 is provided with a first through hole 222 and a second through hole 223. The first through hole 222 is used to pass through the toothed rod 312, and the second through hole 223 is used to pass through the rotating member 321.

[0036] See also Figures 1 to 4 As shown, in one embodiment of this utility model, a guide groove 2113 is provided on the first gear 2111, and the second end of the connector 2112 is slidably disposed in the guide groove 2113. The guide groove 2113 includes two opposing first arc-shaped guide sections 2114 and two opposing second arc-shaped guide sections 2115. The two first arc-shaped guide sections 2114 protrude to the side away from each other, and the two second arc-shaped guide sections 2115 protrude to the side away from each other. The diameter of the circle containing the arc-shaped guide segment 2114 is smaller than the diameter of the circles containing the two second arc-shaped guide segments 2115. The two first arc-shaped guide segments 2114 and the two second arc-shaped guide segments 2115 are arranged alternately and connected sequentially along the circumference of the first gear 2111. When the second end of the connector 2112 is located in the first arc-shaped guide segment 2114, the clamping part 21 is in a clamped state. When the second end of the connector 2112 is located in the second arc-shaped guide segment 2115, the clamping part 21 is in a released state.

[0037] In this embodiment, the first gear 2111 is provided with a guide groove 2113, which includes two first arc-shaped guide sections 2114 protruding away from each other and two similarly protruding second arc-shaped guide sections 2115. The two first arc-shaped guide sections 2114 and the two second arc-shaped guide sections 2115 are arranged alternately along the circumference of the first gear 2111 and are connected in sequence. The second end of the connector 2112 is slidably disposed in the guide groove 2113. When the first gear 2111 rotates, the second end of the connector 2112 slides in the guide groove 2113. Depending on its position (i.e., located in the first arc-shaped guide section 2114 or the second arc-shaped guide section 2115), the clamping or releasing state of the gripper 212 is controlled. Specifically, when the second end of the connector 2112 is located at the first arc-shaped guide section 2114, due to the small diameter of the first arc-shaped guide section 2114, the first gear 2111 pulls the first ends of the two connectors 2112 closer to each other, causing the clamping ends 214 of the two jaws 212 to move away from each other. At this time, the clamping part 21 is in a released state to release the cable. When the second end of the connector 2112 slides to the second arc-shaped guide section 2115, due to the large diameter of the second arc-shaped guide section 2115, the first gear 2111 pushes the first ends of the two connectors 2112 away from each other, causing the clamping ends 214 of the two jaws 212 to move closer to each other. At this time, the clamping part 21 is in a clamping state to clamp the cable.

[0038] See also Figures 1 to 4 As shown, in one embodiment of the present invention, the guide groove 2113 further includes two first transition sections 2116 and two second transition sections 2117. One of the first arc-shaped guide sections 2114 has a first transition section 2116 at both ends, and the other first arc-shaped guide section 2114 has a second transition section 2117 at both ends. The first ends of the two first transition sections 2116 are connected to the corresponding first arc-shaped guide sections 2114. The second end of one of the first transition sections 2116 is connected to the first end of one of the second arc-shaped guide sections 2115, and the second end of the other first transition section 2116 is connected to the first end of the other second arc-shaped guide section 2115. The first ends of the two second transition sections 2117 are connected to the corresponding first arc-shaped guide sections 2114. The second end of one of the second transition sections 2117 is connected to the second end of one of the second arc-shaped guide sections 2115, and the second end of the other second transition section 2117 is connected to the second end of the other second arc-shaped guide section 2115.

[0039] With the above settings, it can be ensured that the second end of the connector 2112 can transition between the first arc-shaped guide section 2114 and the second arc-shaped guide section 2115.

[0040] See also Figures 1 to 4 As shown, in one embodiment of the present invention, a continuous spiral guide groove 323 is provided on the outer wall surface of the rotating member 321 along the length direction of the rotating member 321, and a protrusion 221 adapted to the spiral guide groove 323 is provided on the moving part 22, and the protrusion 221 is slidably disposed in the spiral guide groove 323.

[0041] In this embodiment, the protrusion 221 is located at the starting position of the spiral guide groove 323, and the moving part 22 is stationary. At this time, the cable is not being pulled. When the motor 311 starts, power is transmitted to the rotating part 321 through the meshing of the rack 312 and the second gear 322, causing it to start rotating. As the rotating part 321 rotates, the spiral guide groove 323 guides the protrusion 221 to move along the axial direction of the rotating part 321. The protrusion 221 slides in the spiral guide groove 323, driving the moving part 22 to move linearly in the first direction, thereby achieving cable dragging. By controlling the rotational speed and direction of the motor 311, the rotation of the rotating part 321 can be precisely controlled, thereby further controlling the movement of the protrusion 221 and the moving part 22, achieving precise control of the cable traction speed.

[0042] See also Figures 1 to 3 As shown, in one embodiment of the present invention, the mounting base 10 has a mounting cavity 11, and there are at least two clamping mechanisms 20, which are spaced apart along a first direction.

[0043] In this embodiment, by arranging multiple clamping mechanisms 20 at intervals in the first direction, clamping force can be applied to multiple points of the cable simultaneously, thereby improving the stability and reliability of clamping and preventing the cable from slipping or being damaged due to insufficient or uneven clamping force at a single point during dragging. At the same time, the multiple clamping mechanisms 20 arranged at intervals can distribute the weight of the cable, increase the load-bearing capacity of the device, and enable the device to adapt to dragging heavier or longer cables.

[0044] See also Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a roller 12 is provided at the bottom of the mounting base 10.

[0045] The above settings facilitate the movement of the cable traction device.

[0046] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: An mounting base, a clamping mechanism, and a first driving mechanism are provided. The clamping mechanism includes a clamping part and a moving part. The first driving mechanism can drive the clamping mechanism to switch between a clamping state and a releasing state and drive the moving part to move relative to the mounting base along a first direction. When laying cables, the first driving mechanism drives the clamping mechanism to be in a clamping state to clamp the cable. Then, the moving part moves relative to the mounting base along a first direction under the drive of the first driving mechanism to transport the cable to the designated position. This avoids the inconvenience and safety hazards caused by manual operation and also improves cable laying efficiency.
