Description

Technical Field

[0001] This utility model relates to the field of cable handling technology, specifically a cable reel dragging device for power construction. Background Technology

[0002] Cables are usually wound on cable reels, and the cables are moved by handling the reels. Existing cable handling devices cannot be adjusted according to the size of the reels, so they cannot handle reels of different sizes, resulting in low applicability. In addition, existing cable handling devices cannot fix the reels, which makes it easy for the reels to slip off during handling, causing damage to the reels and affecting handling efficiency.

[0003] Existing patent application CN202421330531.2 discloses an adjustable cable handling and fixing device, belonging to the field of cable handling technology. It includes a main body of the handling device and multiple casters. Two fixing mechanisms are provided on one side of the main body. Each fixing mechanism includes a moving block, and a travel groove is formed on one side of the moving block. A second rack is slidably connected to the inner wall of the travel groove. In this invention, by setting up fixing mechanisms, the pressure plate and pressure block are moved by the weight of the cable and the reel. As the pressure block moves, it presses against the moving plate, causing the moving plate to move the first rack. The movement of the first rack causes the gear to rotate counterclockwise, which in turn moves the second rack and the clamping plate closer to the pressure block. This allows the clamping plate to clamp and fix the reel, preventing the reel and cable from slipping off the device during handling and causing damage to the reel. This improves the stability and efficiency of handling.

[0004] After the two fixing mechanisms of the patent come into contact with each other and the cable reel, the two fixing mechanisms continue to come closer to each other to lift the cable reel. When the two fixing mechanisms lift the cable reel, they will squeeze or rub against the cable reel. Long-term use will cause damage to the fixing mechanisms or the cable reel. Utility Model Content

[0005] To address the problem of how to prevent damage to the cable reel or the fixing mechanism due to squeezing or friction between the two fixing mechanisms when lifting the cable reel, this utility model provides a cable reel dragging device for power construction.

[0006] The technical solution of this utility model is as follows:

[0007] A cable reel dragging device for power construction includes a U-shaped movable support device. The movable support device has multiple rollers at its bottom. The movable support device comprises a telescopic transport body. Support arms are respectively provided on the same side at both ends of the transport body. Grooves are provided on opposite sides of the two support arms, and support rollers are rotatably mounted within these grooves. The two support rollers support the cable reel. When the two support rollers approach each other, they rotate due to the frictional force of the cable reel, thus relieving the friction between the cable reel and the support rollers.

[0008] Furthermore, the conveying body includes a main housing, with a dual-shaft motor located in the middle section inside the main housing. Telescopic housings are located at both ends of the main housing. Each telescopic housing has a threaded hole near the end of the dual-shaft motor. The two power output ends of the dual-shaft motor have threaded rods with opposite thread directions, which are screwed into the threaded holes. The dual-shaft motor drives the telescopic housings to extend or retract from the main housing, facilitating the support of cable reels of different diameters.

[0009] Furthermore, a limiting block is provided at the free end of the threaded rod. This prevents the telescopic housing from becoming loose from the threaded rod, which would cause the telescopic housing to separate from the main housing.

[0010] Furthermore, a power supply is provided at the top of the main housing, and support frames are provided on both sides of the top of the main housing. Handles are provided on the support frames, and controllers are provided on the handles. The power supply and controllers are electrically connected to the dual-output shaft motor, facilitating control of the dual-output shaft motor.

[0011] Furthermore, each of the two supporting arms has a sliding groove on its opposite side, and two sliders are provided inside the sliding groove. An L-shaped limiting plate is hinged to each slider, and the top of each supporting arm has a limiting tooth that fits into the limiting plate. The cable reel is limited by the cooperation between the limiting tooth and the limiting plate.

[0012] Furthermore, the support arm is located on the side of the telescopic housing away from the dual-output shaft motor, and the support roller is made of metal. When the two telescopic housings extend and retract inside the main housing, they cause the two support arms to move away from or closer to each other.

[0013] Furthermore, the rollers are omnidirectional wheels, with multiple omnidirectional wheels respectively located at the bottom of the telescopic housing at the end away from the dual-output shaft motor and at the bottom of the support arm at the end away from the telescopic housing. The omnidirectional wheels facilitate the movement of the two support arms, allowing them to move closer together or further apart, and also facilitate the movement of the device.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1): The structure of this utility model is simple. The cable reel is squeezed by two support rollers. The cable reel is lifted from the ground and supported by the two support rollers. At the same time that the two support rollers support the cable reel, the support rollers and the cable reel will generate friction. When the support rollers are subjected to friction, they rotate to relieve the force and avoid damage to the support rollers or the cable reel due to the large friction, thus ensuring the life of the device and the cable reel.

[0016] (2): This device slides two sliders in the same groove to the two sides of the cable reel respectively. Since the sliders are equipped with L-shaped limiting plates by hinges, it is easy to rotate the limiting plates to the top of the support arm. This ensures that the two limiting plates are located on the two sides of the cable reel respectively, and the limiting plates can be engaged with the limiting teeth on the support arm to ensure the stability of the cable reel during transportation and prevent the cable reel from slipping off the support roller.

[0026] Example

[0027] This embodiment provides a cable reel dragging device for power construction. See [link / reference] Figures 1-4 The device includes a U-shaped movable support device with multiple rollers at its bottom. The movable support device comprises a telescopic transport body 1, with support arms 2 on the same side at both ends of the transport body 1. Each of the two support arms 2 has a groove 11 on its opposite side, within which a support roller 12 is rotatably mounted. The two support rollers 12 support the cable reel 4. When the two support rollers 12 approach each other, they rotate due to the frictional force of the cable reel 4, thus relieving the friction between the cable reel 4 and the support rollers 12.

[0028] The device is moved to the position where the cable reel 4 is placed using rollers. Due to its U-shaped structure, the device is easy to move. The two support arms 2 are inserted into the bottom of the cable reel 4. As the transport body 1 retracts, the support rollers 12 on the two support arms 2 come into contact with the cable reel 4. As the transport body 1 continues to retract, the two support arms 2 continue to move closer to each other. At this time, the cable reel 4 is squeezed by the two support rollers 12, and the cable reel 4 rises from the ground and is supported by the two support rollers 12. While the two support rollers 12 are supporting the cable reel 4, friction is generated between the support rollers 12 and the cable reel 4. When the support rollers 12 are subjected to friction, they rotate to relieve the force and prevent damage to the support rollers 12 or the cable reel 4 due to excessive friction, thus ensuring the lifespan of the device and the cable reel 4.

[0029] The conveying body 1 includes a main housing 8. A dual-shaft motor 6 is located in the middle section of the main housing 8. Telescopic housings 9 are located at both ends of the main housing 8. Each telescopic housing 9 has a threaded hole 10 near the end of the dual-shaft motor 6. The two power output ends of the dual-shaft motor 6 have threaded rods 7 with opposite thread directions, which are screwed into the threaded holes 10. The dual-shaft motor 6 drives the telescopic housing 9 to extend or retract from the main housing 8, facilitating the support of cable reels 4 of different diameters.

[0030] Since the two telescopic housings 9 are sleeved at both ends inside the main housing 8, and are screwed to the threaded rods 7 of the dual-shaft motor 6 in the middle section of the main housing 8 through the threaded holes 10 at the ends, when the dual-shaft motor 6 is working, the telescopic housings 9 can be controlled to extend and retract inside the main housing 8 simultaneously through the two threaded rods 7, so as to drive the two support arms 2 to move closer or further away from each other, which is convenient for supporting cable reels 4 of different diameters and ensuring the versatility of this device.

[0031] The free end of the threaded rod 7 is provided with a limiting block 19 to prevent the telescopic housing 9 from becoming loose from the threaded rod 7 and causing the telescopic housing 9 to separate from the main housing 8.

[0032] When the threaded rod 7 drives the telescopic housing 9 to extend outward from inside the main housing 8, the limiting block 19 at the end of the threaded rod 7 can prevent the operator from continuously controlling the threaded rod 7 to drive the telescopic housing 9 out of the main housing 8, thus ensuring the stability of the device during use.

[0033] The main housing 8 has a power supply 5 on its top, and support frames are provided on both sides of the top of the main housing 8. The support frames are equipped with handles 18, and the handles 18 are equipped with controllers. The power supply 5 and the controllers are electrically connected to the dual-output shaft motor 6, which facilitates the control of the dual-output shaft motor 6.

[0034] The handle 18 and support frame facilitate the movement of the cable reel 4 to the desired location. The power supply 5 provides energy to the dual-output shaft motor 6. The controller can control the forward and reverse rotation of the dual-output shaft motor 6, ensuring effective control of the two support arms 2 moving closer or further apart from each other.

[0035] Each of the two supporting arms 2 has a sliding groove 14 on its opposite side. Two sliders 15 are located inside the sliding groove 14. An L-shaped limiting plate 16 is mounted on each slider 15 via a hinge 17. The top of each supporting arm 2 has a limiting tooth 13 that fits into the limiting plate 16. The cable reel 4 is limited by the cooperation between the limiting tooth 13 and the limiting plate 16.

[0036] After the cable reel 4 is supported, to prevent the cable reel 4 from slipping off the support roller 12 during movement and causing damage to the cable reel 4, two sliders 15 in the same groove 14 are slid to the two sides of the cable reel 4 respectively. Since the sliders 15 are equipped with L-shaped limiting plates 16 through hinges 17, it is easy to rotate the limiting plates 16 above the support arm 2, ensuring that the two limiting plates 16 are located on the two sides of the cable reel 4 respectively, and the limiting plates 16 can be engaged with the limiting teeth 13 on the support arm 2, ensuring the stability of the cable reel 4 during transportation and preventing the cable reel 4 from slipping off the support roller 12.

[0037] The support arm 2 is located on the side of the telescopic housing 9 away from the dual-output shaft motor 6, and the support roller 12 is made of metal. When the two telescopic housings 9 extend and retract inside the main housing 8, they cause the two support arms 2 to move away from or closer to each other, which facilitates the support of cable reels 4 of different diameters. The metal support roller 12 has high rigidity and can support heavier cable reels 4, ensuring the service life of this device.

[0038] The rollers are omnidirectional wheels 3, and multiple omnidirectional wheels 3 are respectively located at the bottom of the telescopic housing 9 at the end away from the dual-output shaft motor 6 and at the bottom of the support arm 2 at the end away from the telescopic housing 9. The omnidirectional wheels 3 facilitate the two support arms 2 to move closer or further apart, and facilitate the movement of this device to drag the cable reel 4 to the desired location.

[0039] In addition, since the cable reel 4 is abutted by the support roller 12, the cable reel 4 can rotate on the support roller 12, which makes it easy to drag the device to the cable laying position and lay the cable at the same time by pulling one end of the cable to remove it from the cable reel 4.

[0040] In this embodiment, the working principle of the cable reel dragging device for power construction is as follows:

[0041] First, move the device to the cable reel 4 location using the casters 3. Then, drive the two support arms 2 away from each other by rotating the dual-axis motor 6 in the forward direction. Next, move the device using the casters 3 to insert the two support arms 2 into the bottom sides of the cable reel 4. Then, drive the dual-axis motor 6 in the reverse direction, bringing the two support arms 2 closer together. The support rollers 12 on the support arms 2 abut against the bottom sides of the cable reel 4. As the support arms 2 continue to move closer together, the two support rollers 12 lift the cable reel 4 from the ground. Next, move the two sliders 15 in the same groove 14 away from each other, ensuring that the two sliders 15 are located on both sides of the cable reel 4. Rotate the limiting plate 16 so that it is positioned on both sides of the cable reel 4, ensuring that the limiting plate 16 engages with the limiting teeth 13. Finally, move the lifted cable reel 4 to the desired location and reverse the above steps to place the cable reel 4 in the desired location.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
