Description

Technical Field

[0001] The present invention relates to the technical field of cables and wires, and in particular to an automatic cable retractor and a use method thereof. Background Art

[0002] Before laying high-voltage cables in the cable trench, fine sand is usually laid in the cable trench to reduce the friction between the cable and the bottom of the trench and protect the cable from mechanical damage; secondly, fine sand has good water permeability, which helps prevent water accumulation in the cable trench and protect the cable from moisture; in addition, fine sand also helps to dissipate heat from the cable and reduce the problem of thermal expansion and contraction caused by temperature changes. In the process of laying high-voltage cables in tunnels, manual pushing of cable retractors is usually used to complete the work. Due to the certain distance between the cable retractor and the cable trench and the limitation of the length of the released cable, the high-voltage cable is often located on the side of the cable trench in the early stage of laying. This layout requires the high-voltage cable to be moved from the side to the middle of the cable trench after the laying work is completed. This process is not only labor-intensive, but also in the process of transferring the high-voltage cable from the side to the middle, the fine sand may be displaced due to the movement, causing the high-voltage cable to directly contact the bottom of the cable trench, increasing the friction between the cable and the bottom of the trench. This friction may not only cause cable damage, but also damage the insulation layer of the cable, affecting the safety and service life of the cable. Summary of the invention

[0040] The sides of the fixed support plate 106 are chamfered to prevent the sides of the fixed support plate 106 from scratching the high-voltage cable 100 .

[0041] The surfaces of the guide pulley 31 and the positioning pulley 5 are both provided with a nylon layer to reduce the friction between the high-voltage cable 100 and the surfaces of the guide pulley 31 and the positioning pulley 5 .

[0042] A method for using an automatic cable retractor comprises the following steps:

[0043] Step 1: Pass the high-voltage cable 100 wound on the reel 1 through the automatically arranged cable retractor;

[0044] Step 2: Arrange the high-voltage cable 100 by an automatic cable retractor and place it in the middle of the cable trench 200;

[0045] Step 3: Use a tractor to drive the automatically arranged cable retractor to move along the cable trench 200, release the high-voltage cable 100, and arrange it in the middle position of the cable trench 200;

[0046] Step 4: The high-voltage cable 100 is arranged in the cable trench 200 so as to be separated from the automatically arranged cable retractor.

[0047] First, before the present invention works, Figure 2As shown, the staff first passes the high-voltage cable 100 through the electric fixing block 2, the guide assembly 3, the burying assembly 4 and other parts. When working, the present invention is arranged next to the cable trench 200 and connected to the present invention through an external tractor, and the present invention is pulled to the left. Before moving to the left, the high-voltage cable 100 is released by rotating the reel 1, and at the same time, the high-voltage cable 100 passes through the fixed channel 2001 and the two guide channels 3001, and is guided by the positioning pulley 5. At this time, the positioning pulley 5 is located in the cable trench 200 and close to one side of the fixed support plate 106. The high-voltage cable 100 is guided in the cable trench 200 by the positioning pulley 5, so that the high-voltage cable 100 is located in the middle part of the cable trench 200. Before laying the high-voltage cable 100 according to the present invention, the workers will lay fine sand in the cable trench 200 to reduce the friction between the cable and the trench bottom and protect the cable from mechanical damage. Therefore, during the movement of the present invention to the left, the high-voltage cable 100 is Figure 4 The laying starts from the state shown, so that during the laying process of the high-voltage cable 100, under the guidance of the positioning pulley 5, it is located in the middle of the cable trench 200 throughout the whole process, avoiding the complicated arrangement steps of initially laying the high-voltage cable 100 on the side of the cable trench 200 and moving it to the middle after completion. It also avoids the displacement of fine sand due to the movement of the high-voltage cable 100, which increases the friction between the high-voltage cable 100 and the trench bottom, thereby damaging the high-voltage cable 100 and affecting its safety and service life.

[0048] When the present invention is pulled by a vehicle and moves to the left along the cable trench 200 to lay the high-voltage cable 100, after the high-voltage cable 100 is guided by the positioning pulley 5, it passes through the guide opening 4003, and then when the present invention moves to the left, the burying block 44 presses on the surface of the fine sand, and during the movement of the burying block 44 to the left, part of the fine sand is shoveled up, and the shoveled fine sand enters from the burying channels 4004 on both sides of the guide opening 4003. During the continuous movement of the burying block 44 to the left, fine sand continues to enter from the burying channel 4004 and gathers in the gathering channel 4005. Then, the fine sand gathered in the gathering channel 4005 is discharged from the burying channel 4004. Fig.11 The narrow eight-shaped mouth of the collecting channel 4005 shown falls down to bury the laid high-voltage cable 100, thereby burying the high-voltage cable 100 while it is being laid, effectively reducing the overheating problem of the high-voltage cable 100 caused by heat dissipation, and protecting the high-voltage cable 100 from vibration damage. This process simplifies the step of separately burying the traditional high-voltage cable 100 after laying, thereby improving the construction efficiency and the safety of the high-voltage cable 100.

[0049] During the laying of the high-voltage cable 100, in order to ensure the smooth operation, before starting to lay the high-voltage cable 100, the workers will place the cover plate of the cable trench 200 next to the cable trench 200 and ensure that the cover plate is against the tunnel wall for subsequent use. During the placement of the cover plate, the cover plate may accidentally fall into the cable trench 200, which may hinder the normal operation of the present invention and the laying of the high-voltage cable 100. In order to solve this problem, the present invention provides a first guide plate 41, a second guide plate 42 and a third guide plate 43. When the present invention moves to the left, the first guide plate 41, the second guide plate 42 and the third guide plate 43 are The guide plate 42 and the third guide plate 43 will move along, scoop up any fallen cover plates and place them on the first guide plate 41, thereby preventing the cover plates from obstructing the laying of the high-voltage cable 100. Once the cover plates are safely placed on the first guide plate 41, the workers will then remove the cover plates from the first guide plate 41 to ensure that the cable trench 200 is unobstructed so as to continue the laying of the high-voltage cable 100. Through this design, the present invention can effectively deal with the obstructions that may be caused by the cover plates, ensure the smooth progress of the laying of the high-voltage cable 100, and at the same time reduce manual intervention and improve construction efficiency and safety.

[0050] In order to ensure that the first guide plate 41, the second guide plate 42 and the third guide plate 43 can smoothly pass through the cable trench 200 where there may be curved parts, the first guide plate 41, the second guide plate 42 and the third guide plate 43 are connected to each other by a hinge 4002, which helps to improve the flexibility and passability of the first guide plate 41, the second guide plate 42 and the third guide plate 43 in the curved cable trench 200. This connection method allows a certain amount of activity space between the plates, so that the entire structure can be flexibly adjusted and smoothly passed when encountering a curved part of the cable trench 200. Through the connection of the hinge 4002, the first guide plate 41, the second guide plate 42 and the third guide plate 43 can form a continuous, bendable guide path, ensuring that the continuity and effectiveness of the guiding function can be maintained at any curved part of the cable trench 200. Through this arrangement, the first guide plate 41 of the present invention can adapt to the bending changes of the cable trench 200, ensure the smooth guidance and processing of the cover plate in the cable trench 200, and improve the flexibility and efficiency of construction.

[0051] In order to ensure that the high-voltage cable 100 will not be damaged due to excessive bending during the laying process, the present invention effectively guides the high-voltage cable 100 through parts such as the electric fixing block 2, the guide component 3, the burying component 4, and the positioning pulley 5, so that when it is released from the reel 1, it is not in a free hanging state, but is restricted to a specific bending state. This arrangement can avoid sudden bending of the high-voltage cable 100 when it is transferred to the cable trench 200, thereby preventing damage to the high-voltage cable 100 due to excessive bending. By controlling the bending degree of the high-voltage cable 100, the safety and integrity of the high-voltage cable 100 during the laying process can be ensured, its service life can be extended, and the reliability of power transmission can be ensured.

[0052] In order to adapt to the non-bending characteristics of the high-voltage cable 100 and reduce the damage caused to it during the laying process, each guide component 3 is set to be rotatable, so that the guide component 3 can adapt to the bending requirements of the high-voltage cable 100 within a certain range, thereby reducing damage to the high-voltage cable 100. Since the height of the high-voltage cable 100 when it is released from the reel 1 is uncertain, the electric fixing block 2 can follow the height change of the high-voltage cable 100 and move up and down along the slide rail 102. When the electric fixing block 2 moves downward along the slide rail 102, the supporting arc plate 105 can limit the downward bending curvature of the high-voltage cable 100 to a certain extent, which helps to reduce the damage that the high-voltage cable 100 may suffer due to excessive bending, thereby improving construction efficiency and the service life of the high-voltage cable 100.

[0053] It should be noted that in order to protect the high-voltage cable 100 from being damaged when passing through the channel formed by the fixed support plate 106 and the first guide plate 41, the fixed support plate 106 is chamfered and a universal bead 4001 is provided on the first guide plate 41 to guide the high-voltage cable 100 and prevent the high-voltage cable 100 from being scratched by the edges and corners of the fixed support plate 106 and the first guide plate 41.

[0054] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the appended claims of the application.
