Description

Technical Field

[0001] This utility model belongs to the technical field of construction equipment for overhead power distribution lines, and specifically relates to a vertical cable laying frame suitable for overhead power distribution lines. Background Technology

[0002] To improve power supply quality and ensure safe and stable power supply, the power industry is upgrading its services and strengthening safety management. Under these circumstances, the workload of supporting projects for power expansion has increased significantly, service deadlines are becoming increasingly tight, and the pressure on safety management is growing. In distribution network renovation projects, short-distance line upgrades account for the majority, especially in rural areas. However, the complex terrain of rural areas, with its crisscrossing mountains, hills, and ravines, and limited construction space, presents significant challenges to construction. At the same time, users' demands for timely power access are constantly increasing, adding further challenges to construction.

[0003] Traditional power distribution network upgrades often use large winches for wiring, but due to the complex terrain in rural areas, these large winches are bulky, have poor mobility, and are difficult to transport and deploy. Their operation is complex, and the start-up, commissioning, and operation processes are time-consuming, making it difficult to meet tight service deadlines. Furthermore, the high costs of purchasing, transporting, and maintaining them do not meet cost control requirements.

[0004] Given the limitations of large winches in rural power distribution network upgrades, the laying of short-distance power distribution network lines currently relies primarily on manual labor. While manual laying can adapt to complex terrain to some extent, it has significant drawbacks. Specifically, manual laying is inefficient, requiring workers to expend considerable physical strength and time to complete the line laying, thus extending the construction period. Furthermore, manual laying consumes substantial human resources; the conductor reels are large, typically 1.5-2 meters in diameter. Manual laying requires 4-5 people standing at four points on the reel to unwind the conductor from the reel, while another person drags the free end of the conductor towards the target location. An additional person is needed to pull the unwinding conductor between the reel and the free end. Utility Model Content

[0005] In view of this, the present invention provides a vertical cable laying frame suitable for overhead power distribution lines to solve the technical problem that manual cable laying in the prior art requires a lot of manpower and is inefficient.

[0006] To achieve the above objectives, this application adopts the following approach:

[0007] A vertical cable laying frame suitable for overhead power distribution lines is used to hold conductor reels for power distribution. Construction workers can lay the conductor to the required length by dragging the free end of the conductor. The frame includes a base, a rotating disk, and a cable laying control component. The rotating disk is located above the base, and the cable laying control component is located between the base and the rotating disk. Both the rotating disk and the cable laying control component are mounted on the base. The rotating disk holds the conductor reel, and the free end of the conductor passes through the cable laying control component. The cable laying control component locks the rotating disk and releases it in response to the pulling force exerted by the operator when dragging the free end of the conductor, allowing the rotating disk to rotate relative to the base and lay the conductor to the required length.

[0008] A connecting rod is vertically arranged at the center of the base, and the rotating disk is rotatably mounted on the connecting rod; a plurality of rolling elements are provided between the rotating disk and the base so that the rotating disk and the base are rotatably connected.

[0009] Preferably, the wire feeding control assembly includes a ratchet, a pawl, an L-shaped adjustable rocker arm, and an elastic connector. The ratchet is coaxially mounted on the rotating disk. The pawl is located at the lower end of the L-shaped adjustable rocker arm and is lockably connected to the ratchet. The lower end of the L-shaped adjustable rocker arm is rotatably mounted on the base. A guide pulley is provided at the upper end of the L-shaped adjustable rocker arm to guide the free end of the wire smoothly through. One end of the elastic connector is connected to the L-shaped adjustable rocker arm, and the other end is connected to the base. Pulling the L-shaped adjustable rocker arm causes the pawl to engage the ratchet. When the operator drags the free end of the wire, the guide pulley senses the pulling force, causing the L-shaped adjustable rocker arm to swing, thereby disengaging the pawl from the ratchet. This allows the rotating disk to rotate via the rolling element, extending the wire to the desired length. When dragging the free end of the wire stops, the rotating disk continues to rotate due to inertia. The elastic connector pulls the L-shaped adjustable rocker arm, causing the pawl to engage the ratchet, thus stopping the rotating disk from rotating.

[0010] Preferably, the rolling element is a swivel ball, and a ball seat is provided on the base. The swivel ball is located inside the ball seat and rolls in contact with the bottom of the rotating disk.

[0011] Preferably, the rotating disk is further provided with a pair of anti-collision members, which are respectively located on both sides of the L-shaped adjustable rocker arm to prevent the L-shaped adjustable rocker arm from colliding with the rolling element.

[0012] Preferably, the connecting rod is a screw, and either end of the screw is detachably connected to the base.

[0013] Preferably, the rotating disk is a support frame, and an annular protrusion is provided on the inner wall of the support frame along the circumference. The wire coil is placed on the annular protrusion to make it more stable.

[0014] Preferably, the L-shaped adjustable rocker arm includes a first telescopic section, an L-shaped fixed section, and a second telescopic section. The first telescopic section is horizontally disposed on the rotating disk, and the second telescopic section is vertically disposed on the rotating disk. The L-shaped fixed section is located between the first telescopic section and the second telescopic section and is used to connect the first telescopic section and the second telescopic section. When the first telescopic section extends horizontally, the horizontal position of the guide pulley can be adjusted. When the second telescopic section extends vertically, the height of the guide pulley can be adjusted.

[0015] Preferably, at least two lifting members are also provided on the edge of the base, and the two lifting members are symmetrically arranged at 180° between each other on the edge of the base to facilitate its movement.

[0016] Preferably, the lifting component is a lifting lug.

[0017] In the aforementioned vertical cable-laying frame applicable to overhead power distribution lines, the rotating disk and the base are rotatably connected via rolling elements. The conductor reel for the power distribution network is placed on the rotating disk, with the center hole of the reel aligned with the connecting rod. The free end of the conductor is then passed through the cable-laying control assembly. When cable laying is required, the worker drags the free end of the conductor. When the cable-laying control assembly senses the pulling force exerted by the worker, it releases the rotating disk, causing it to rotate relative to the base via the rolling elements, thus laying the conductor to the required length. When the worker stops dragging the free end, the cable-laying control assembly no longer senses the pulling force, locking the rotating disk and stopping the cable laying. Compared to manual cable laying, the cable-laying frame provided in this application requires only one person to complete the cable laying operation for one conductor reel, saving 4-5 workers per reel. Furthermore, the pulling force generated when dragging the free end of the conductor causes the rotating disk to rotate around the connecting rod, enabling continuous cable laying and thus greatly improving work efficiency.

Detailed Implementation

[0026] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are also given. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please refer to Figures 1 to 7In one specific embodiment, a vertical cable-laying frame suitable for overhead power distribution lines is provided for placing conductor reels for power distribution. Construction workers can lay the conductor to the required length by dragging the free end of the conductor. The frame includes a base 100, a rotating disk 200, and a cable-laying control component. The rotating disk 200 is located above the base 100, and the cable-laying control component is located between the base 100 and the rotating disk 200. Both the rotating disk 200 and the cable-laying control component are mounted on the base 100. The rotating disk 200 is used to hold the conductor reels, and the free end of the conductor passes through... The wire feeding control component locks the rotating disk 200 and releases it in response to the pulling force exerted by the operator when dragging the free end of the wire, allowing the rotating disk to rotate relative to the base and thus feed the wire to the required length. A connecting rod 100 is vertically arranged at the center of the base 100, and the rotating disk 200 is rotatably mounted on the connecting rod 100. A plurality of rolling elements 210 are provided between the rotating disk 200 and the base 100 to allow the rotating disk 200 and the base 100 to be rotatably connected.

[0029] The base 100 and the rotating disk 200 can be of any shape, but are preferably circular in this embodiment; and the size of the base 100 and the rotating disk 200 can be selected according to the size of the wire reel. In a preferred embodiment, the size of the base 100 is slightly larger than the size of the rotating disk 200.

[0030] In use, first, place the vertical wire laying frame in the construction area of ​​the overhead power distribution line, ensuring the base 100 is stable. Place the wire reel on the rotating disk 200, aligning the center hole of the wire reel with the connecting rod 100, thus completing the reel installation. Then, pass the free end of the wire on the wire reel through the wire laying control component and pull it to the desired construction position. When wire laying is required, the construction worker drags the free end of the wire. The wire moves smoothly under the guidance of the wire laying control component. When the wire laying control component senses the pulling force of the operator on the free end of the wire, it releases the rotating disk 200, causing the rotating disk 200 to rotate relative to the base 100 via the rolling element 210, thereby achieving continuous wire laying. When the wire has been laid to the required length, stop dragging the wire. The wire laying control component no longer senses the pulling force of the operator on the free end of the wire, thus locking the rotating disk 200 and stopping wire laying.

[0031] Compared with manual wire laying, the wire laying frame provided by this application only requires one person to complete the wire laying operation of one wire reel. The wire laying of one wire reel can save 4-5 manpower. Moreover, the tension generated when dragging the free end of the wire will cause the rotating disc to rotate around the connecting rod, thereby realizing the continuous laying of the wire. Therefore, the work efficiency is greatly improved.

[0032] In one specific embodiment, the wire feeding control assembly includes a ratchet 410, a pawl 420, an L-shaped adjustable rocker arm 310, and an elastic connector 430. The ratchet 410 is coaxially mounted on the rotating disk 200. The pawl 420 is located at the lower end of the L-shaped adjustable rocker arm 310 and is lockably connected to the ratchet 410. The lower end of the L-shaped adjustable rocker arm 310 is rotatably mounted on the base 100. A guide pulley 320 is provided at the upper end of the L-shaped adjustable rocker arm 310 to guide the free end of the wire to pass smoothly. One end of the elastic connector 430 is connected to the L-shaped adjustable rocker arm 310, and the other end is connected to the base 100. The base 100 is used to pull the L-shaped adjustable rocker arm 310, causing the pawl 420 to engage the ratchet 410. When the operator drags the free end of the wire, the guide pulley 320 senses the pulling force, causing the L-shaped adjustable rocker arm 310 to swing, thereby disengaging the pawl 420 from the ratchet 410. This allows the rotating disk 200 to rotate via the rolling element 210, laying the wire to the required length. When dragging the free end of the wire stops, the rotating disk 200 continues to rotate due to inertia. The elastic connector 430 pulls the L-shaped adjustable rocker arm 310, causing the pawl 420 to engage the ratchet 410, stopping the rotating disk 200 from rotating. This design achieves automatic braking of the rotating disk 200, eliminating the need for additional manual operation, improving construction efficiency, and ensuring that the rotating disk 200 stops rotating immediately when the wire is no longer being dragged, thus improving the accuracy and precision of wire laying.

[0033] In addition, the position of the L-shaped adjustable rocker arm 310 can be adjusted according to the actual situation, including the horizontal and vertical positions, so that its guide pulley 320 is at a suitable height and angle to adapt to different working conditions.

[0034] To enable the rotating disk 200 to rotate more flexibly, the rolling element 210 is a omnidirectional ball joint, and a ball seat is provided on the base 100. The omnidirectional ball joint is located within the ball seat and rolls in contact with the bottom of the rotating disk 200. The omnidirectional ball joint has the characteristic of omnidirectional rolling, which allows the rotating disk 200 to rotate more flexibly when subjected to the drag force of the wire, reducing problems of poor rotation caused by friction or jamming. Because the omnidirectional ball joint makes rolling contact with the bottom of the rotating disk 200, the direct friction between the rotating disk 200 and the base 100 is reduced, making the wire release process smoother and avoiding wire wear or difficulties in wire release caused by excessive friction.

[0035] Considering that the L-shaped adjustable rocker arm 310 may collide with the rolling element 210 (universal ball) when adjusting its position or under external force, such physical impact may cause damage, deformation, or detachment of the rolling element 210, thereby affecting the rotational flexibility and overall stability of the rotating disk 200, a pair of anti-collision members 220 are further provided on the rotating disk 200. The pair of anti-collision members 220 are located on both sides of the L-shaped adjustable rocker arm 310 to prevent the L-shaped adjustable rocker arm 310 from colliding with the rolling element 210. By preventing direct impact between the L-shaped adjustable rocker arm 310 and the rolling element 210, the anti-collision members 220 reduce the risk of equipment failure and improve the overall reliability of the vertical cable reel. The anti-collision members 220 are supported by elastic material.

[0036] Specifically, the connecting rod 100 is a screw, and either end of the screw is detachably connected to the base 100, which improves the ease of operation.

[0037] Considering that when the wire reel is placed on the rotating disk 200, manual dragging of the wire end can cause the reel to move, affecting the wire feeding efficiency, in a preferred embodiment, the rotating disk 200 is a support frame. The inner wall of the support frame has annular protrusions along its circumference. The wire reel is placed on these annular protrusions for greater stability. The annular protrusions provide additional support and fixation for the wire reel when placed on the rotating disk 200 (support frame). This design reduces the problem of uneven wire feeding caused by shaking or shifting of the wire reel during the feeding process, thereby improving work efficiency.

[0038] In one specific embodiment, the L-shaped adjustable rocker arm 310 includes a first telescopic section 311, an L-shaped fixed section 312, and a second telescopic section 313. The first telescopic section 311 is horizontally disposed on the rotating disk 200, and the second telescopic section 313 is vertically disposed on the rotating disk 200. The L-shaped fixed section 312 is located between the first telescopic section 311 and the second telescopic section 313 and is used to connect the first telescopic section 311 and the second telescopic section 313. When the first telescopic section 311 extends and retracts horizontally, the horizontal position of the guide pulley 320 can be adjusted. When the second telescopic section 313 extends and retracts vertically, the height of the guide pulley 320 can be adjusted.

[0039] The design of the first telescopic section 311 and the second telescopic section 313 allows the guide pulley 320 to be independently adjusted in both the horizontal and vertical directions. This flexibility allows construction personnel to precisely adjust the position of the guide pulley 320 according to actual construction needs, to adapt to the conductor release requirements at different heights and angles. By adjusting the telescopic section of the L-shaped adjustable rocker arm 310, construction personnel can easily position the guide pulley 320 to the most suitable position, thereby reducing friction and resistance during conductor release, which not only improves the convenience of the release operation but also ensures that the conductor can be released smoothly.

[0040] To adapt to different construction scenarios, in a preferred embodiment, at least two lifting members 120 are also provided on the edge of the base 100. The two lifting members 120 are symmetrically arranged at 180° between each other on the edge of the base 100, facilitating its movement. The lifting members 120 make the movement of the vertical cable laying frame more convenient and efficient. Construction personnel or handling equipment can easily lift or move the cable laying frame to the required position using the lifting members 120, reducing the difficulty and labor intensity of manual handling. Moreover, the ease of movement of the vertical cable laying frame allows it to adapt to different construction scenarios. Whether in urban power distribution network renovation, rural power grid upgrades, or other overhead power line construction, the cable laying frame can be easily moved to the required position for cable laying operations.

[0041] In one specific embodiment, the lifting component 120 is a lifting lug.

[0042] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
