Abstract
Description
Technical Field
[0001] This application relates to the field of power cable unwinding technology, and in particular to a novel power cable unwinding reel. Background Technology
[0002] Power cables are electrical devices used to transmit electrical energy. They consist of conductors, insulation layers, and sheaths. Power cables are typically used to transmit low, medium, and high voltage electrical energy and can be used in building interiors, urban power grids, industrial manufacturing, transportation, and other fields. After production, power cables are generally wound into coils before storage and transportation. The purpose of winding is to protect the power cables from damage or tangling, and it also saves space for storage and transportation. When laying power cables, most installations use reels, from which the wire is released during operation.
[0003] The published patent document CN220131557U discloses a cable laying device for power line construction, including a base plate. A guide mechanism is slidably connected to the top of the base plate, and the guide mechanism includes a fixed frame, a T-shaped block fixed to the bottom of the fixed frame, and a guide wheel rotatably connected to the fixed frame. Support plates are fixed at both ends of the top of the base plate. A first clamping plate is rotatably connected to one outer wall of one of the support plates, and an adjustment mechanism is slidably inserted into one outer wall of the other support plate. The adjustment mechanism includes a fixed plate and a second clamping plate rotatably connected to one outer wall of the fixed plate. However, since the size of the power cable reel varies due to different needs and requirements, the two clamping plates of fixed size in this device have poor versatility and cannot meet the needs of unwinding reels of different sizes. Utility Model Content
[0004] In view of the shortcomings of the prior art, this application provides a new type of power cable reel, which overcomes the shortcomings of the prior art and aims to solve the problem that the existing reels cannot meet the needs of unwinding wire coils of different sizes.
[0005] To achieve the above objectives, this application provides the following technical solution: a novel power cable reel, comprising a base, a fixing plate fixedly mounted on the upper surface of the base, a guide unit fixedly mounted on one side of the fixing plate, a handle rotatably connected to the inside of the fixing plate via a bearing, a turntable fixedly connected to the front end of the handle via a bearing through the fixing plate, a threaded rod fixedly connected to the center of the outer surface of the turntable, a sleeve slidably fitted onto the outer surface of the threaded rod, a connecting block fixedly connected to the outer wall of the sleeve, a collar threadedly fitted onto the outer surface of the threaded rod outside the sleeve, a sliding groove penetrating the outer surface of the turntable on one side of the threaded rod, a sliding block slidably connected inside the sliding groove, an abutment block fixedly connected to the side of the sliding block away from the fixing plate, a diagonal brace rotatably connected to the side wall of the abutment block, and the other end of the diagonal brace rotatably connected to the connecting block.
[0006] By adopting the above technical solution, the bushing is driven to move axially along the threaded rod by rotating the collar. The axial displacement of the bushing is transmitted to the diagonal brace through the connecting block. Through the cooperation between the sliding groove, sliding block, abutment block and diagonal brace, the linear motion is converted into a radial expansion action, so that the abutment block expands outward and abuts against the inner wall of the cable roll, thereby fixing the cable roll and meeting the needs of different sized cable rolls.
[0007] As a preferred embodiment of this application, the sliding block is T-shaped, and the turntable is located between the sliding block and the abutment block.
[0008] By adopting the above technical solution, the sliding block is prevented from detaching from the inside of the sliding groove, and the matching design of the sliding block and the sliding groove ensures the accuracy of linear motion.
[0009] As a preferred technical solution of this application, the sliding groove, sliding block, abutment block and connecting block are all provided in threes and correspond one to one. The three sliding grooves, sliding blocks, abutment blocks and connecting blocks are evenly distributed in a circular array about the central axis of the threaded rod.
[0010] By adopting the above technical solution, multiple abutment blocks are evenly distributed with threaded rods in a circumferential array, ensuring that all abutment blocks expand outward or contract inward synchronously to form a stable circular support surface, thereby achieving the fixation of the cable reel.
[0011] As a preferred technical solution of this application, the guide unit includes a guide frame fixedly installed on the upper surface of the base, and a rectangular groove is provided on the top of the guide frame. Two parallel guide wheels are rotatably connected inside the rectangular groove.
[0012] By adopting the above technical solution, the direction of cable movement is guided by two parallel guide wheels.
[0013] As a preferred technical solution of this application, the number of guide units is two, and a tension adjustment unit is provided on the upper surface of the base between the two guide units. The tension adjustment unit includes a tension frame fixedly installed on the upper surface of the base. An adjustment groove is opened inside the tension frame. An adjustment block is slidably connected inside the adjustment groove. A tension wheel is rotatably sleeved on the outer surface of the adjustment block. A spring is fixedly connected to the bottom of the adjustment block. The lower end of the spring is fixedly connected to the inner wall of the adjustment groove.
[0014] By adopting the above technical solution, when the cable tension changes, the tension wheel is driven by external force to slide the adjusting block along the adjusting groove, and the spring generates a reaction force through deformation, forming an automatic balancing mechanism to adapt to the tension change and ensure the stability of the unwinding process.
[0015] As a preferred embodiment of this application, both the guide wheel and the tension wheel are made of stainless steel, and the outer surfaces of both the guide wheel and the tension wheel are polished.
[0016] By adopting the above technical solutions, stainless steel has excellent rust resistance and can adapt to harsh environments such as humidity and salt spray in power construction. The polishing process can effectively reduce scratch damage to the cable surface.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. In this utility model, the sleeve is driven to move axially along the threaded rod by rotating the collar, and the axial displacement of the sleeve is transmitted to the diagonal brace by the connecting block. Through the cooperation between the sliding groove, the sliding block, the abutment block and the diagonal brace, the linear motion is converted into a radial expansion action, so that the abutment block expands outward and abuts against the inner wall of the cable roll, thereby fixing the cable roll and satisfying the use of different sized cable rolls.
[0019] 2. In this utility model, the direction of cable movement is guided by the guide unit. When the cable tension changes, the tension wheel is driven by external force to slide the adjustment block along the adjustment groove. The spring generates a reaction force through deformation, forming an automatic balancing mechanism to adapt to tension changes and ensure the stability of the unwinding process.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0028] like Figure 1 - Figure 4 As shown, this embodiment provides a novel power cable reel, including a base 1. A fixing plate 2 is fixedly installed on the upper surface of the base 1. A guide unit 3 is fixedly installed on one side of the fixing plate 2. A handle 5 is rotatably connected to the inside of the fixing plate 2 via a bearing. The front end of the handle 5 passes through the fixing plate 2 via a bearing and is fixedly connected to a turntable 6. A threaded rod 7 is fixedly connected to the center of the outer surface of the turntable 6. A sleeve 8 is slidably sleeved on the outer surface of the threaded rod 7. A connecting block 13 is fixedly connected to the outer wall of the sleeve 8. A collar 14 is threadedly sleeved on the outer surface of the threaded rod 7 outside the sleeve 8. A sliding groove 9 is formed through the outer surface of the turntable 6 on one side of the threaded rod 7. The internal sliding connection includes a sliding block 10. A stop block 11 is fixedly connected to the side of the sliding block 10 away from the fixed plate 2. A diagonal brace 12 is rotatably connected to the side wall of the stop block 11. The other end of the diagonal brace 12 is rotatably connected to the connecting block 13. In use, the sleeve 8 is driven to move axially along the threaded rod 7 by rotating the collar 14. The axial displacement of the sleeve 8 is transmitted to the diagonal brace 12 through the connecting block 13. Through the cooperation between the sliding groove 9, the sliding block 10, the stop block 11 and the diagonal brace 12, the linear motion is converted into a radial expansion action, so that the stop block 11 expands outward and abuts against the inner wall of the cable coil to fix the cable coil, thereby meeting the use of different sized cable coils.
[0029] In this embodiment, as Figure 3 As shown, the sliding block 10 is T-shaped, and the turntable 6 is located between the sliding block 10 and the abutment block 11. During use, it prevents the sliding block 10 from disengaging from the inside of the sliding groove 9. The matching design of the sliding block 10 and the sliding groove 9 ensures the accuracy of linear motion.
[0030] In this embodiment, as Figure 3 As shown, there are three sliding grooves 9, three sliding blocks 10, three abutment blocks 11 and three connecting blocks 13, and they are all arranged in a one-to-one correspondence. The three sliding grooves 9, three sliding blocks 10, three abutment blocks 11 and three connecting blocks 13 are evenly distributed in a circular array about the central axis of the threaded rod 7. In use, multiple abutment blocks 11 are evenly distributed in a circular array about the threaded rod 7 to ensure that all abutment blocks 11 expand outward or contract inward synchronously to form a stable circular support surface, thereby achieving the fixation of the cable reel.
[0031] In this embodiment, as Figure 2 As shown, the guide unit 3 includes a guide frame 31 fixedly installed on the upper surface of the base 1. A rectangular groove 32 is provided on the top of the guide frame 31. Two parallel guide wheels 33 are rotatably connected inside the rectangular groove 32. In use, the two parallel guide wheels 33 guide the direction of cable movement.
[0032] In this embodiment, as Figure 2 and 4 As shown, there are two guide units 3, and a tension adjustment unit 4 is set on the upper surface of the base 1 between the two guide units 3. The tension adjustment unit 4 includes a tension frame 41 fixedly installed on the upper surface of the base 1. An adjustment groove 42 is opened inside the tension frame 41. An adjustment block 44 is slidably connected inside the adjustment groove 42. A tension wheel 45 is rotatably sleeved on the outer surface of the adjustment block 44. A spring 43 is fixedly connected to the bottom of the adjustment block 44. The lower end of the spring 43 is fixedly connected to the inner wall of the adjustment groove 42. In use, when the cable tension changes, the tension wheel 45 is driven by external force to slide the adjustment block 44 along the adjustment groove 42. The spring 43 generates a reaction force through deformation, forming an automatic balancing mechanism to adapt to tension changes and ensure the stability of the unwinding process.
[0033] In this embodiment, as Figure 2 and 4 As shown, both guide wheel 33 and tension wheel 45 are stainless steel components, and the outer surfaces of both guide wheel 33 and tension wheel 45 are polished. When in use, stainless steel has excellent rust resistance and can adapt to harsh environments such as humidity and salt spray in power construction. The polishing process can effectively reduce scratch damage to the cable surface.
[0034] The working principle of this utility model is as follows: When using the new type of power cable reel of this application, the sleeve 8 is driven to move axially along the threaded rod 7 by rotating the collar 14. The axial displacement of the sleeve 8 is transmitted to the diagonal brace 12 through the connecting block 13. Through the cooperation between the sliding groove 9, the sliding block 10, the abutment block 11 and the diagonal brace 12, the linear motion is converted into a radial expansion action, so that the abutment block 11 expands outward and abuts against the inner wall of the cable reel, thus fixing the cable reel and satisfying the use of reels of different sizes. During the unwinding process, the guide unit 3 guides the direction of cable movement. When the cable tension changes, the tension wheel 45 is driven by external force to slide the adjusting block 44 along the adjusting groove 42. The spring 43 generates a reaction force through deformation, forming an automatic balancing mechanism to adapt to tension changes and ensure the stability of the unwinding process.
