Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, specifically to a line-laying device used in power engineering construction. Background Technology

[0002] In power engineering construction, cables are typically laid, requiring appropriate cable-laying equipment to support the wound cables, facilitate cable stretching during construction, and reel in excess cable. For example, a cable-laying device for power engineering construction, with announcement number CN216598742U, includes a traveling device for moving and releasing the cable, and a limiting device for guiding the cable release. The limiting device has two symmetrically arranged lifting devices for vertical movement. The traveling device includes a base plate with four evenly distributed wheels at its four corners. A traction plate is welded to one side of the base plate, and a first bracket is mounted on the base plate. A cable reel roller is mounted on the first bracket, and a second bracket is located on one side of the first bracket. The limiting device includes a support beam with a limiting ring mounted on its top. This cable-laying device for power engineering construction ensures applicability to different cable-laying heights through height adjustment; ensures cable-laying stability through limiting support; and ensures continuous height adjustment through rotational height adjustment. However, the overhead line device used in power engineering construction still has the following drawbacks in actual use:

[0003] Traditional cable-laying equipment causes the cable to extend further due to inertia after it is stretched, which can affect the construction. After the cable stretching stops, there is no structure to limit and fix it in time. To address these issues, there is an urgent need for innovative design based on the existing cable-laying equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a cable-laying device for power engineering construction, in order to solve the problem mentioned in the background art that after the cable is stretched, the cable will continue to extend due to inertia, which will have a certain impact on the construction. After the cable stretching is stopped, there is no structure to limit and fix it in time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire-laying device for power engineering construction, comprising a support frame, wherein a winding roller is rotatably mounted on the inner side of the support frame, and a cable is wound on the outer side of the winding roller;

[0006] It also includes: a support plate, fixed to the edge of the support frame, the upper surface of the support plate having a movable groove, and the support block forming a sliding structure with the support plate through the movable groove, the support block being fixed to the bottom of the limiting tube, and the limiting tube being positioned above the support plate;

[0007] A limiting component is disposed inside the limiting tube, and the limiting component is used to keep the cable stationary after the cable stops stretching.

[0008] Preferably, the movable groove has the same length as the winding roller, the inner bottom surface of the limiting tube is an arc surface structure, and the inner top surface of the limiting tube is a horizontal surface. When the cable is stretched at different positions, the limiting tube can be driven to slide on the support plate.

[0009] Preferably, the limiting component includes a fixed cavity disposed inside the limiting tube, and air supply holes are reserved at equal intervals above the fixed cavity. The inner bottom surface of the limiting tube is made of rubber. When the inner bottom surface of the limiting tube is squeezed, the gas in the fixed cavity can be squeezed out and adsorbed onto the surface of the cable through the air supply holes.

[0010] Preferably, the limiting component further includes a movable plate disposed on the top surface of the limiting tube, and the movable plate and the limiting tube form a rotating structure. The movable plate is inclined and can be rotated when the cable pushes the movable plate.

[0011] Preferably, the surface of the movable plate is connected to the limiting tube by a spring, and a fixing block is fixed at the edge of the movable plate. The end of the fixing block away from the movable plate is fixedly connected to the connecting rope. When the movable plate is pulled, it can rotate to drive the fixing block to engage with the fixing hole.

[0012] Preferably, the other end of the connecting rope is provided with a connecting block, and an adjusting ball is fixed at the end of the connecting block away from the connecting rope. When the adjusting ball is pulled, the movable plate can be rotated through the connecting rope.

[0013] Preferably, the connecting rope slides through the fixing hole, and the fixing hole is opened at the top of the limiting tube. When the connecting block is stuck inside the fixing hole, the fixing block inside the fixing hole can be pushed out.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the overhead line equipment used in power engineering construction has a structure to limit and fix the cable when the cable stretching is stopped, preventing the cable from continuing to extend due to inertia and reducing the impact on construction. The specific details are as follows:

[0015] 1. During the pulling of the cable, it can contact the movable plate and drive it to rotate. When the pulling stops, the spring's rebound can drive the movable plate to rotate in the opposite direction and contact the cable surface, pressing it to achieve initial limitation. This can prevent the cable from continuing to extend due to inertia.

[0016] Furthermore, the movable plate presses the cable downwards, causing it to apply pressure to the inner bottom surface of the limiting tube. Through this squeezing, the gas in the fixed cavity can be squeezed out from the air inlet, so that the cable can be adsorbed onto the air inlet, further limiting the cable and ensuring its stability after it stops pulling.

[0017] 2. To prevent the moving plate from affecting the cable winding process, the adjusting ball can be pulled to rotate the moving plate via the connecting rope, so that the fixing block is locked in the fixing hole to facilitate cable passage. After the operation is completed, the connecting block can be locked in the fixing hole, and the fixing block in the fixing hole can be pushed out to restore the moving plate to its tilted state.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] To address the problems existing in the prior art, this embodiment provides the following technical solution: a power line overhead line device for power engineering construction, comprising a support frame 1, a winding roller 2 rotatably mounted on the inner side of the support frame 1, and a cable 3 wound on the outer side of the winding roller 2; further comprising: a support plate 4 fixed to the edge of the support frame 1, a movable groove 5 formed on the upper end surface of the support plate 4, and a support block 7 forming a sliding structure with the support plate 4 through the movable groove 5, the support block 7 being fixed to the bottom of a limiting tube 6, and the limiting tube 6 being positioned above the support plate 4; and a limiting component disposed inside the limiting tube 6, the limiting component being used to keep the cable 3 stationary after the cable 3 stops being stretched.

[0028] Existing cable-laying equipment, after stretching the cable, causes the cable to extend further due to inertia, which can affect construction. There is a lack of a structure to promptly limit and fix the cable after stretching stops. The movable groove 5 is the same length as the winding roller 2. The inner bottom surface of the limiting tube 6 is arc-shaped, and the inner top surface of the limiting tube 6 is horizontal. The limiting assembly includes a fixed cavity 8 inside the limiting tube 6, with air inlets 9 evenly spaced above the fixed cavity 8. The inner bottom surface of the limiting tube 6 is made of rubber. The limiting assembly also includes a movable plate 10 on the inner top surface of the limiting tube 6. The movable plate 10 is inclined and forms a rotating structure with the limiting tube 6. The surface of the movable plate 10 is connected to the limiting tube 6 by a spring, and a fixing block 11 is fixed at the edge of the movable plate 10. The end of the fixing block 11 away from the movable plate 10 is fixedly connected to the connecting rope 12. The other end of the connecting rope 12 is provided with a connecting block 14, and an adjusting ball 15 is fixed at the end of the connecting block 14 away from the connecting rope 12. The connecting rope 12 slides through the fixing hole 13, and the fixing hole 13 is opened at the top of the limiting tube 6. First, the cable 3 is passed through the inside of the limiting tube 6 and used by stretching. As the cable 3 extends, the limiting tube 6 can slide within the movable groove 5 via the support block 7, depending on its winding position. This prevents the cable 3 from bending excessively. During pulling, the cable 3 contacts the movable plate 10, causing it to rotate, thus not obstructing the cable 3's passage. When pulling the cable 3 stops, the spring's rebound causes the movable plate 10 to rotate in the opposite direction and contact the surface of the cable 3, pressing it down to achieve initial limiting. This prevents the cable 3 from continuing to extend due to inertia. When the movable plate 10 presses the cable 3 downwards, it causes the cable 3 to apply pressure to the inner bottom surface of the limiting tube 6, thus compressing the cable. The gas in the fixed cavity 8 is squeezed out from the air outlet 9, so that the cable 3 can be attracted to the air outlet 9, further limiting the cable 3 and ensuring its stability after it stops pulling. When it is necessary to rewind the excess cable 3, in order to avoid the influence of the movable plate 10 on the cable 3, the adjusting ball 15 can be pulled to drive the movable plate 10 to rotate through the connecting rope 12, so that the fixing block 11 can be locked in the fixing hole 13, which facilitates the passage of the cable 3. After the operation is completed, the adjusting ball 15 is locked in the fixing hole 13 through the connecting block 14, which can push out the fixing block 11 in the fixing hole 13 and allow the movable plate 10 to return to the tilted state.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
