Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically a gas engineering pressure pipeline laying device. Background Technology

[0002] In the construction of urban gas projects, petrochemicals, and other fields, the laying of pressure pipelines is a crucial process. Traditional pipeline laying methods typically rely on large equipment such as cranes and excavators for lifting and positioning, or on simple supports and clamps for fixing. These traditional methods have many drawbacks: simple clamps have poor versatility, are difficult to adapt to pipes of different diameters, and the clamping and fixing effect is not ideal. Furthermore, when lifted by cranes and excavators, displacement or loosening can easily occur during pipe docking and welding, affecting construction accuracy and quality safety. Moreover, adjusting the height and moving the pipeline horizontally is very inconvenient, often requiring repeated adjustments of equipment or the use of multiple jacks, making the operation cumbersome and inefficient.

[0003] Therefore, there is an urgent need to develop a pressure pipeline laying device that integrates clamping and fixing, flexible movement, precise lifting and fine adjustment functions, and can adapt to various pipe diameters. Utility Model Content

[0004] The purpose of this invention is to provide a gas engineering pressure pipeline laying device to overcome the shortcomings of the above-mentioned technology.

[0005] To achieve the above objectives, this utility model provides a gas engineering pressure pipeline laying device, including at least two laying clamps. Each laying clamp includes a first clamp, a second clamp, and a base. The first clamp is detachably connected to the top surface of the base via connecting bolts. The top surface of the base is provided with a slide rail, and a slider is provided inside the slide rail. The second clamp is fixedly connected to the slider. Both the first clamp and the second clamp have folded edges at their tops, which are connected by fastening bolts. The bottom surface of the base is provided with a support plate and a hydraulic cylinder. The support plate is in the shape of an inverted U, and universal wheels are provided at the four corners of the bottom surface of the support plate. The hydraulic cylinder is located inside the support plate, and a lifting platform is provided at the output end of the hydraulic cylinder. A through channel for the lifting platform to rise and fall is provided on the support plate. Both the first clamp and the second clamp are provided with lifting rings.

[0006] Preferably, both the slide and the slider have convex cross-sectional shapes. The slide has a limiting hole and the slider has a limiting groove. The limiting hole and the limiting groove are connected by a limiting bolt.

[0007] Preferably, the inner side of the support plate is provided with reinforcing ribs.

[0008] Preferably, each laying fixture is equipped with at least two hydraulic cylinders.

[0009] The beneficial effects of this utility model are as follows: 1. By setting a sliding clamp two, the distance between the two clamps can be flexibly adjusted, and both clamp one and clamp two can be disassembled and replaced, thereby stably clamping pipes of different diameters. The folded edges at the top of the two clamps are connected by fastening bolts, achieving all-round clamping and fastening force for the pressure pipe, ensuring the stability of the pipe during hoisting, docking and welding processes, and effectively preventing the pipe from rolling or shifting.

[0010] 2. The casters at the bottom of the support plate allow for stable planar movement of the pressure pipeline, enabling flexible adjustment of the pipeline in the horizontal direction. After the horizontal position is adjusted, the hydraulic cylinder drives the lifting platform to descend, lifting the casters off the ground and raising the height of the pressure pipeline. This allows for precise and stable adjustment of the pipeline height, facilitating accurate alignment of the pipeline with fittings or the port of another section of pipeline.

[0011] 3. It integrates multiple functions such as clamping, lifting, and moving, reducing construction costs and site requirements. The lifting rings on the two clamps can be used with lifting equipment to facilitate the lifting of the two laying clamps, improving operational flexibility and safety. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] Reference Figure 1-2This embodiment provides a gas pipeline pressure laying device, including at least two laying clamps. The laying clamps include clamp 1, clamp 2, and base 3. Clamp 1 is detachably connected to the top surface of base 3 by connecting bolts 4. The top surface of base 3 is provided with a slide rail 5, and a slider 6 is provided in the slide rail 5. Clamp 2 is fixedly connected to the slider 6. Clamp 1 and clamp 2 are both provided with folded edges 7 at the top, and the folded edges 7 are connected by fastening bolts 8. The bottom surface of base 3 is provided with a support plate 9 and a hydraulic cylinder 10. The support plate 9 is in the shape of an inverted U, and universal wheels 11 are provided at the four corners of the bottom surface of the support plate 9. The hydraulic cylinder 10 is located inside the support plate 9, and a lifting platform 12 is provided at the output end of the hydraulic cylinder 10. The support plate 9 is provided with a through channel 13 for the lifting platform 12 to rise and fall. Clamp 1 and clamp 2 are both provided with lifting rings 14. According to the actual situation, the lifting rings 14 can be connected to external lifting straps for lifting the pressure pipeline.

[0017] Both the slide rail 5 and the slider 6 have convex cross-sectional shapes. The slide rail 5 is provided with a limiting hole 15, and the slider 6 is provided with a limiting groove 16. The limiting hole 15 and the limiting groove 16 are connected by a limiting bolt 17, which facilitates the replacement of the specifications of the clamp 2 and the adjustment of the position of the clamp 2.

[0018] The inner side of the support plate 9 is provided with reinforcing ribs 18 to increase the support effect of the support plate 9.

[0019] Each laying fixture is equipped with at least two hydraulic cylinders 10 to increase the support stability of the lifting platform 12.

[0020] Based on the diameter of the pipe to be laid, determine the specifications of clamp 1 and clamp 2, and adjust the distance between clamp 2 and clamp 1 to fit the pipe diameter. Then, tighten the limiting bolts to fix clamp 2. Place the pipe between clamp 1 and clamp 2, and tighten the two clamps using the fastening bolts 8 on the top folded edge 7 to securely hold the pipe. Depending on actual needs, the pressure pipe can be lifted to the required installation position using hoisting equipment and hoisting rings 14, and initially positioned using casters 11. Alternatively, if the pressure pipe is installed on the ground, it can be initially positioned by moving it to the designated laying position using the casters 11 at the bottom of the support plate 9. Multiple laying clamps can be used to support a long pipe.

[0021] When the pipe height needs to be adjusted for precise alignment, the hydraulic cylinder 10 is activated. The piston rod of the hydraulic cylinder 10 pushes the lifting platform 12 downward, causing the lifting platform 12 to pass through the through-pass 13 and rest on the ground. This lifts the entire clamping mechanism and the pipe together, achieving the pipe height adjustment. During this process, the casters 11 are lifted off the ground along with the support plate 9, and the lifting platform 12 bears the entire load, ensuring stability during operation.

[0022] After the pipeline position is adjusted, subsequent operations such as welding or connection can be carried out. After the operation is completed, first separate clamp 1 and clamp 2, remove clamp 2, operate hydraulic cylinder 10 to raise the lifting platform 12, and the casters 11 will re-contact the ground. Move the device away and proceed with the laying of the next section of pipeline.

[0023] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
