Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically to an auxiliary device for power engineering pipeline construction. Background Technology

[0002] In electrical engineering, conduit laying typically refers to the installation of electrical protection conduits. Their core function is to provide mechanical protection (against compression and impact), environmental isolation (moisture-proof, corrosion-proof, and anti-corrosion), and path guidance for wires and cables, ensuring the safe and stable operation of the electrical system. The requirements for conduit laying vary significantly depending on the scenario (e.g., indoor, outdoor, underground, wall-mounted), and must be implemented comprehensively based on conduit material selection, construction specifications, and acceptance standards.

[0003] In the process of power engineering construction, right-angle connections need to be avoided when making spatial transitions. This can be achieved by laying inclined pipes to increase the bending angle and protect the cables laid inside the pipes. When laying inclined pipes, hoisting equipment is needed to suspend the pipes in the air, and then other positioning equipment is used to fix the inclination angle of the pipes. This requires the coordinated operation of multiple equipment, which not only reduces the laying efficiency but also increases the construction cost. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for power engineering pipeline construction. The drive component not only clamps the steel cable but also drives it, adjusting the length of the steel cables on both sides so that the pipeline clamped by the clamp is tilted under the action of gravity. In conjunction with other kit equipment, the pipeline can be transferred. Moreover, it can be adjusted at multiple angles, which facilitates the laying and welding of the pipeline, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for power engineering pipeline construction, comprising: Lifting structure; The hoisting structure includes a steel cable, two sets of clamps installed on the pipe, and a load-bearing structure for adjusting the steel cable. The steel cable passes through the load-bearing structure and its two ends are connected to the clamps respectively. The load-bearing structure includes a box, and two sets of guide wheels for guiding the steel cable are rotatably connected to both sides of the inner cavity of the box via bearings. The inner cavity of the box is provided with a drive assembly for adjusting the steel cable left and right.

[0007] Preferably, both ends of the steel cable are provided with buckles, and the top of the upper clamp is fixed with a fixing ring, and the buckles are fastened inside the fixing ring.

Detailed Implementation

[0016] 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.

[0017] This utility model provides, for example Figures 1-5 An auxiliary device for power engineering pipeline construction is shown, comprising: Lifting structure; The hoisting structure includes a steel cable 1, two sets of clamps 2 installed on the pipe, and a load-bearing structure 3 for adjusting the steel cable 1. The steel cable 1 passes through the load-bearing structure 3 and its two ends are connected to the clamps 2 respectively. The load-bearing structure 3 includes a box 31. Two sets of guide wheels 32 for guiding the steel cable 1 are rotatably connected to both sides of the inner cavity of the box 31 through bearings. The inner cavity of the box 31 is provided with a drive assembly 33 for adjusting the steel cable 1 left and right. The steel cable 1 is supported by the load-bearing structure 3, and then driven by the drive component 33 to drive the steel cable 1 and adjust the length of the steel cables 1 on both sides. With the help of the clamp 2, the pipe can be tilted when suspended. By driving the steel cable 1, the angle of the pipe can be adjusted, which facilitates the precise hoisting of the pipe when laying the inclined pipe. This device is not only highly practical, but can also speed up the laying of inclined pipes without the help of other equipment.

[0018] Among them, such as Figure 2 As shown: The clamp 2 includes an upper clamp 21 and a lower clamp 22. Rubber protective pads 23 are embedded on the inner side of the upper clamp 21 and the lower clamp 22. Mounting holes are opened at both ends of the upper clamp 21 and the lower clamp 22, and bolt posts 24 are movably installed in the mounting holes. Mounting nuts 25 are threaded to both ends of the bolt posts 24. The upper clamp 21 and the lower clamp 22 are installed on the outside of the pipe through the bolt posts 24 and the mounting nuts 25, so that the two ends of the steel cable 1 are connected to two points on the pipe. The rubber protective pads 23 can not only protect the pipe and prevent the upper clamp 21 and the lower clamp 22 from scratching the outer wall of the pipe, but also prevent the clamp 2 from sliding between the pipe and the pipe.

[0019] Furthermore, such as Figure 2-3 As shown: Both ends of the steel cable 1 are equipped with buckles 4, and the top of the upper clamp 21 is fixed with a fixing ring 5. The buckles 4 are fastened inside the fixing ring 5. The buckles 4 and the fixing ring 5 facilitate the connection of the steel cable 1 to the clamp 2.

[0020] Preferred, such as Figure 3-5 As shown: The drive assembly 33 includes a drive wheel 331 and a limit wheel 332 rotatably connected to the housing 31 via bearings. The steel cable 1 is movably engaged between the drive wheel 331 and the limit wheel 332. A drive motor 333 is fixed to the outside of the housing 31. The output shaft of the drive motor 333 passes through the inner cavity of the housing 31 and is fixedly connected to one end of the drive wheel 331. The drive motor 333 drives the drive wheel 331, which in turn transports the steel cable 1 in conjunction with the limit wheel 332. The length of the steel cable 1 on both sides of the housing 31 is adjusted, thereby adjusting the tilt of the pipeline.

[0021] The drive motor 333 is connected to an external controller via a cable, which allows for manual forward and reverse operation of the drive motor 333.

[0022] It is worth noting that, such as Figure 5 As shown: The drive wheel 331 and the limit wheel 332 are provided with a groove 6 on their outer sides. The steel cable 1 is located in the groove 6. By setting the groove 6, the contact area between the drive wheel 331, the limit wheel 332 and the steel cable 1 is increased, the friction is increased, and the steel cable 1 is prevented from sliding with the limit wheel 332 and the drive wheel 331, which would cause the pipe tilt angle to change.

[0023] In a further preferred embodiment, such as Figure 5 As shown: Two sets of meshing gears 7 are fixed on the outer sides of the drive wheel 331 and the limit wheel 332. The gears 7 are located on both sides of the groove 6. By setting the gears 7, the drive wheel 331 drives the limit wheel 332, avoiding insufficient friction between the drive wheel 331 and the limit wheel 332, which would cause the limit wheel 332 to be unable to restrict the steel cable 1 and cause the limit wheel 332 to rotate in the opposite direction.

[0024] In addition, such as Figure 3 As shown: A counterweight 8 is fixed on the other side of the housing 31. The weight of the counterweight 8 is equal to that of the drive motor 333. The counterweight 8 improves the balance of the housing 31 and prevents the center of gravity of the housing 31 from shifting, which would cause severe local wear on the steel cable 1, the limit wheel 332, and the drive wheel 331.

[0025] In practical use, the upper clamp 21 and lower clamp 22 are clamped on the outside of the pipe. Then, the bolt column 24 is passed through the mounting hole and locked with the mounting nut 25 to clamp the pipe. Then, the buckles 4 at both ends of the steel cable 1 are connected to the fixing rings 5 ​​on the upper clamp 21. Then, the box 31 is suspended by the hoisting equipment. Then, the drive motor 333 drives the drive wheel 331 to rotate. The drive wheel 331 uses the gear 7 to synchronously drive the limit wheel 332 to clamp and transport the steel cable 1, so that the length of the steel cable 1 on both sides of the box 31 changes. Using the gravity of the pipe, the pipe is naturally tilted. The digital display inclinometer is magnetically attached to the pipe to realize the intuitive adjustment of the pipe tilt angle. Then, it is transferred to the designated position and connected with other pipes. Finally, it is fixed by welding.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
