Description

Technical Field

[0001] This utility model relates to the technical field of cable laying devices, specifically a cable laying device for the installation of electrical equipment on construction sites. Background Technology

[0002] Cable laying devices for electrical equipment installation at construction sites refer to the collective term for specialized tools, machinery, and auxiliary components used to safely and efficiently transport power cables, control cables, etc., from storage points (such as cable reels) to target installation locations, such as cable trenches, cable trays, conduits, and equipment terminals. Their core functions include the stable release and traction of cables via cable laying frames and traction machines, limiting the cable laying path to prevent deviation using guide rollers and limiting grooves, and protecting the cable insulation layer from scratches or compression through wear-resistant contact components. They are suitable for laying cables of different cross-sections and lengths, significantly improving laying efficiency, reducing labor intensity, and ensuring the installation quality and safety of cables and subsequent electrical systems.

[0003] However, currently, cable laying devices commonly use a structure with two flat conveying rollers to transport cables. In this design, the contact area between the flat conveying rollers and the cable is relatively limited, and the conveying principle relies heavily on the friction between the two to drive the cable forward. This "small contact area + squeezing friction" mode is not only prone to cable slippage and unstable conveying speed due to insufficient friction, but may also scratch the outer insulation layer of the cable due to local pressure concentration, and even cause local deformation of the cable. In addition, the specifications of the cables to be laid in actual construction vary greatly, and traditional laying devices often lack flexible adaptability and adjustment capabilities. The roller spacing is mostly fixed, which is usually only convenient for stable conveying of a single specification of cable. When facing construction site scenarios where multiple specifications of cables are laid alternately, construction personnel need to frequently change the adapting device, which affects the overall construction efficiency of cable laying.

[0004] The purpose of this utility model is to provide a cable laying device for the installation of electrical equipment on construction sites, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable laying device for electrical equipment installation at construction sites, comprising a laying plate, and further comprising: A support frame is fixed to one side of the top of the laying plate. Four limiting plates are also fixedly connected to the top of the laying plate. An adjusting component is provided inside the support frame.

[0006] Preferably, the adjusting component further includes a motor, which is fixed to one side of the support frame. The output end of the motor extends through the interior of the support frame and is fixedly connected to the first conveying roller. A limiting groove is formed inside the support frame.

[0007] Preferably, a support rod is fixedly connected inside the second conveying roller, and both sides of the support rod extend to the outside of the limiting groove and are rotatably connected to a connecting frame via bearings.

[0015] 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.

[0016] Please see Figure 1 - Figure 4 As shown, a cable laying device for electrical equipment installation at a construction site includes a laying plate 1, and further includes: A support frame 2 is fixed to one side of the top of the laying plate 1. Four limiting plates 3 are also fixedly connected to the top of the laying plate 1. An adjusting component 4 is provided inside the support frame 2. The adjusting component 4 includes a first conveying roller 401 and a second conveying roller 403. The limiting shell 5 is fixed to the top of the limiting plate 3. The top of the limiting shell 5 is fixedly connected to the extension plate 6. The support frame 2 and the limiting plate 3 are conveniently fixed and installed through the laying plate 1. The adjustment component 4 set inside the support frame 2 mainly increases the contact area between the first conveying roller 401 and the second conveying roller 403 in a funnel shape to improve the stability during the laying and conveying process. At the same time, the distance between the two can be manually adjusted to improve the applicability of the device.

[0017] The adjusting component 4 also includes a motor 402, which is fixed to one side of the support frame 2. The output end of the motor 402 extends into the interior of the support frame 2 and is fixedly connected to the first conveying roller 401. A limiting groove 404 is formed inside the support frame 2. A support rod 405 is fixedly connected inside the second conveying roller 403. Both sides of the support rod 405 extend to the outside of the limiting groove 404 and are rotatably connected to a connecting frame 406 via bearings. A screw 407 is rotatably connected inside the connecting frame 406. The bottom of the screw 407 is rotatably connected to the support frame 2, and a torsion block 408 is fixedly connected to the top of the screw 407. By opening the output end of the motor 402, the first conveying roller 401 can be directly driven to rotate. This utilizes friction to transport the cable. The limiting groove 404 facilitates the limiting of the support rod 405. The support rod 405, in conjunction with the second conveying roller 403 rotatably connected to the surface, also facilitates the limiting of the cable. If the user needs to adjust the distance between the second conveying roller 403 and the first conveying roller 401 to accommodate the transport of cables of different specifications, the user can rotate the torsion block 408. As the torsion block 408 rotates, it will drive the screw 407 to rotate. At this time, the connecting bracket 406 threaded to the surface of the screw 407 will drive the support rod 405 to move up and down inside the limiting groove 404. As the support rod 405 moves, it will drive the second conveying roller 403 to move and fit against the surface of the cable.

[0018] Rubber strips 409 are fixed in a ring array on the surface of both the first conveying roller 401 and the second conveying roller 403. Both the first conveying roller 401 and the second conveying roller 403 are funnel-shaped. The rubber strips 409 on the surface of both the first conveying roller 401 and the second conveying roller 403 can increase the contact friction with the cable, thereby ensuring the stability of cable laying and conveying. The funnel-shaped arrangement of the first conveying roller 401 and the second conveying roller 403 increases the contact surface from one side to two sides on a single roller, thereby improving the contact friction with the cable, ensuring stable conveying, and also adapting to the conveying of cables of different specifications.

[0019] A first guide roller 7 is rotatably connected between two limiting plates 3. A second guide roller 8 is rotatably connected to both sides inside the limiting shell 5. A fixing plate 9 is slidably connected inside the two extension plates 6. A third guide roller 10 is rotatably connected between the two fixing plates 9. A spring 11 is fixedly connected between the bottom of one side of the fixing plate 9 and the limiting shell 5. A limiting rod 12 that slides inside the fixing plate 9 is fixedly connected to the top of the limiting shell 5. The first guide roller 7 is rotatably connected inside the limiting plate 3 to facilitate support of the bottom of the cable. The second guide roller 8 is rotatably installed inside the limiting shell 5 to limit the position of both sides during cable transportation. When the cable is transported through the top of the first guide roller 7, the third guide roller 10 will be affected by different specifications of cables, which will drive the fixing plate 9 to move inside the limiting shell 5 and stretch the spring 11 to adapt to the large cable body. The limiting rod 12 is slidably connected inside the fixing plate 9 to improve the stability of the fixing plate 9 during movement.

[0020] Working principle: First, based on the cable width, the screw 407 is rotated by turning the torsion block 408. As the screw 407 rotates, the connecting frame 406 drives the support rod 405 to move within the limiting groove 404. The movement of the support rod 405 also causes the second conveying roller 403 to rise, facilitating the fitting of cables of different specifications. Then, the cable is inserted between the first conveying roller 401 and the second conveying roller 403, and the motor 402 is turned on to drive the first conveying roller 401 to rotate. The surfaces of the first conveying roller 401 and the second conveying roller 403 are then used to... The rubber strip 409 increases the friction between the cable and the cable, thereby ensuring stable cable delivery and laying. Subsequently, the cable passes over the third guide roller 10 at the top of the first guide roller 7. The cable will be affected by different specifications of the cable, which will drive the fixing plate 9 to move inside the limiting shell 5 and stretch the spring 11 to adapt to the large cable body. The limiting rod 12 is slidably connected inside the fixing plate 9, which can improve the stability of the fixing plate 9 during movement. In addition, the setting of the second guide roller 8 can also limit the delivery position on both sides of the cable, effectively preventing the cable from deviating during delivery.
