Description

An automatic cable retraction device for building construction Technical Field

[0001] This utility model relates to the field of cable winding and unwinding technology, specifically to an automatic cable winding and unwinding device for building construction. Background Technology

[0002] Automatic cable winding and unwinding devices for construction are specialized equipment used in the construction engineering field to achieve efficient cable winding and unwinding through mechanization and automation. Their core function is to replace traditional manual operation, solving problems such as time-consuming, easily damaged, and unsafe cable management during construction. They are widely applicable to construction sites, municipal engineering projects, tunnel construction, and other scenarios, typically using a motor-driven winding roller to wind and unwind cables.

[0003] However, existing automatic cable winding and unwinding devices require manual replacement of different winding rollers when winding and unwinding different cables because each type of cable has a minimum allowable bending radius. This consumes a lot of manpower, and the surface of the cable will become dirty during the winding and unwinding process. Some dust and small stones may cause damage to the cable sheath during the winding process.

[0004] Therefore, there is a need to provide an automatic cable retraction and deployment device for building construction. Summary of the Invention

[0005] The purpose of this utility model is to provide an automatic cable winding and unwinding device for building construction, in order to solve the problems mentioned in the background art of existing automatic cable winding and unwinding devices. When winding and unwinding cables, each type of cable has a minimum allowable bending radius, so different winding rollers need to be manually changed when winding and unwinding different cables. This requires a lot of manpower, and the surface of the cable will become dirty during the winding and unwinding process. Some dust and small stones may cause damage to the cable sheath during the winding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic cable winding and unwinding device for building construction, comprising a base plate, with movable wheels installed at the four corners of the bottom of the base plate, a winding and unwinding assembly fixedly installed at one end of the top of the base plate, an adjusting assembly for adjusting the diameter of the winding roller fixedly installed on the inner side of the winding and unwinding assembly, a pushing assembly fixedly connected to one end of the adjusting assembly, and a clamping and cleaning assembly drivingly connected to the winding and unwinding assembly.

[0007] Preferably, a control panel is fixedly installed at one corner of the top of the base plate. A retraction switch and an adjustment switch are fixedly installed on the surface of the control panel. The device can be centrally controlled through the control panel, avoiding the need for staff to run back and forth to work and improving work efficiency.

[0008] Preferably, the retraction assembly includes a mounting frame, a side plate rotatably mounted in the middle of the mounting frame, four sliding grooves equally spaced on the side plate, a first pulley fixedly mounted at one end of the side plate, a motor fixedly mounted on one side of the first pulley, the motor fixedly mounted on the mounting frame, the motor electrically connected to an external power supply via a retraction switch, a sliding block slidably mounted inside each of the four sliding grooves, an adjusting plate fixedly mounted on the top of each sliding block, and a baffle fixedly mounted at one end of each of the four adjusting plates.

[0009] Preferably, the adjustment assembly includes a shaft, which is fixedly installed at the center of one side of the side plate. A sliding rod is slidably installed on the outside of the shaft. Four first mounting blocks are equidistantly installed on the outside of the sliding rod. A connecting rod is rotatably installed in the middle of the first mounting blocks. A second mounting block is rotatably installed at one end of the connecting rod. The four second mounting blocks are respectively fixedly installed on the inner side of the four adjustment plates. In construction sites where cable types need to be frequently changed, the traditional solution requires manual disassembly of the reel and replacement of equipment. By adjusting the diameter of the take-up roller, the changeover time is reduced, adapting to frequent switching scenarios.

[0010] Preferably, the pushing component includes a mounting platform, which is fixedly mounted on a base plate. An electric push cylinder is fixedly mounted on the top of the mounting platform. A rotating bearing is fixedly mounted on the output end of the electric push cylinder. One end of the sliding rod is fixedly mounted inside the rotating bearing. The electric push cylinder is electrically connected to an external power supply through a push switch to ensure that the diameter change of the winding roller during the diameter change process is precisely matched with the cable specification. The electric push rod can be preset with different extension lengths by the control system to automatically adjust the diameter of the winding roller to the optimal matching value.

[0011] Preferably, the clamping and cleaning assembly includes two mounting plates and two cleaning rollers. The two mounting plates are symmetrically mounted on the base plate. A mounting shell is fixedly mounted on the top of each mounting plate. Two fixing posts are fixedly mounted inside the mounting shell. Springs are sleeved on the outer sides of the fixing posts. Sliding plates are slidably mounted on the outer sides between the corresponding two fixing posts. One cleaning roller is rotatably mounted between the two sliding plates, and the other cleaning roller is rotatably mounted between the two mounting plates. A second pulley is fixedly mounted on one end of the lower cleaning roller. A transmission belt is internally connected to the second pulley. One end of the transmission belt is connected to the first pulley. The cleaning assembly operates synchronously with the retraction and extension actions, without requiring equipment interruption or additional procedures, thus improving construction efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By adjusting and pushing the components, the take-up roller can be adjusted in diameter via the push and pull of the electric push rod, making it adaptable to the winding of different cables. This eliminates the need for manual replacement of the take-up roller, thus improving work efficiency.

[0014] The clamping assembly cleans the cable surface synchronously during retraction and extension by means of pulleys and drive belts, preventing contaminants from seeping into the gaps in the cable sheath and thus preventing corrosion or wear of the insulation layer. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please refer to Figures 1-5. This utility model provides an automatic cable winding and unwinding device for building construction, including a base plate 1.

[0024] Furthermore, the take-up and unwind assembly includes a mounting frame 4, a side plate 5 rotatably mounted in the middle of the mounting frame 4, four sliding grooves 6 equally spaced on the side plate 5, a first pulley 7 fixedly mounted at one end of the side plate 5, a motor 8 fixedly mounted on one side of the first pulley 7, the motor 8 fixedly mounted on the mounting frame 4, and the motor 8 electrically connected to an external power supply through a take-up and unwind switch. Sliding blocks 9 are slidably mounted inside each of the four sliding grooves 6, and adjusting plates 10 are fixedly mounted on the top of the sliding blocks 9. Baffles 11 are fixedly mounted at one end of each of the four adjusting plates 10. The side plate 5, the four adjusting plates 10, and the four baffles 11 form a take-up roller. The motor 8 drives the first pulley 7 to rotate, which in turn drives the fixedly connected side plate 5 to rotate, thus performing the take-up and unwinding operation of the cable.

[0025] Furthermore, the adjustment assembly includes a shaft 12, which is fixedly installed at the center of one side of the side plate 5. A sliding rod 13 is slidably installed on the outside of the shaft 12. Four first mounting blocks 14 are equidistantly installed on the outside of the sliding rod 13. A connecting rod 15 is rotatably installed in the middle of the first mounting block 14. A second mounting block 16 is rotatably installed at one end of the connecting rod 15. The four second mounting blocks 16 are respectively fixedly installed on the inner sides of the four adjustment plates 10. The pushing assembly includes a mounting platform 27, which is fixedly installed on the base plate 1. An electric push cylinder 26 is fixedly installed on the top of the mounting platform 27. A rotary bearing 25 is fixedly installed at the output end of the electric push cylinder 26. One end of the sliding rod 13 is fixedly installed inside the rotating bearing 25. The electric push cylinder 26 is electrically connected to an external power supply through a push switch. The electric push cylinder 26 pushes or pulls the sliding rod 13 to slide on the shaft 12. Through the cooperation of the connecting rod 15 with the first mounting block 14 and the second mounting block 16, the four adjusting plates 10 are pushed or pulled, so that the four adjusting plates 10 slide inside the four sliding grooves 6 through the sliding block 9, thereby realizing the change of diameter of the winding roller to adapt to different cables. The output end of the electric push cylinder 26 is fixedly installed outside the rotating bearing 25, and one end of the sliding rod 13 is fixedly installed inside the rotating bearing 25.

[0026] Furthermore, the clamping and cleaning assembly includes two mounting plates 19 and two cleaning rollers 24. The two mounting plates 19 are symmetrically mounted on the base plate 1. A mounting shell 20 is fixedly mounted on the top of the mounting plates 19. Two fixing posts 21 are fixedly mounted inside the mounting shell 20. Springs 22 are sleeved on the outer side of the fixing posts 21. Sliding plates 23 are slidably mounted on the outer side between the corresponding two fixing posts 21. One cleaning roller 24 is rotatably mounted between the two sliding plates 23, and the other cleaning roller 24 is rotatably mounted between the two mounting plates 19. A second pulley 18 is fixedly mounted on one end of the lower cleaning roller 24. A transmission belt 17 is internally connected to the second pulley 18. One end of belt 17 is connected to the first pulley 7 for transmission. When the motor 8 starts to retract and extend the cable, it drives the first pulley 7 to rotate. The first pulley 7 drives the second pulley 18 to rotate through the transmission belt 17. When the second pulley 18 rotates, it drives one of the cleaning rollers 24 to rotate. The cable is placed between the two cleaning rollers 24. The cable is squeezed against the upper cleaning roller 24, which causes the two sliding plates 23 to slide upward along the fixed column 21 and squeeze the spring 22. The spring 22 is stressed and applies a squeezing force to the two sliding plates 23, which drives the upper cleaning roller 24 to squeeze the cable. The surface of the cable is cleaned by the cooperation of the two cleaning rollers 24.

[0027] In this embodiment of the application, when the cable is being wound up or down, the motor 8 is started by the winding / unwinding switch on the control panel 3, which drives the first pulley 7 to rotate. At the same time, the fixedly connected side plate 5 is also rotated to wind up or unwind the cable. When the motor 8 starts winding up or unwinding the cable, it drives the first pulley 7 to rotate. The first pulley 7 drives the second pulley 18 to rotate through the transmission belt 17. When the second pulley 18 rotates, it drives one of the cleaning rollers 24 to rotate. The cable is squeezed against the cleaning roller 24 above, which causes the two sliding plates 23 to slide upward along the fixed column 21 and squeeze the spring 22. The spring 22 is stressed and applies a squeezing force to the two sliding plates 23, which drives the cleaning roller 24 above to squeeze the cable. The surface of the cable is cleaned by the cooperation of the two cleaning rollers 24. When different cables need to be wound up, the electric push cylinder 26 is started by adjusting the switch. The electric push cylinder 26 pushes or pulls the sliding rod 13 to slide on the shaft 12. Through the cooperation of the connecting rod 15 with the first mounting block 14 and the second mounting block 16, it pushes or pulls the four adjusting plates 10, so that the four adjusting plates 10 slide inside the four sliding grooves 6 through the sliding block 9, thereby realizing the change of diameter of the winding roller to adapt to different cables, and thus winding up different cables.
