Description

Technical Field

[0001] This utility model belongs to the field of pipe socket technology, specifically relating to a socket assembly device for large-diameter steel-reinforced composite pipes. Background Technology

[0002] With the development of society, the chemical and materials fields are changing rapidly. Nowadays, chemical pipelines generally use steel-reinforced composite pipes, which have the advantages of high compressive strength, wear resistance, impact resistance, corrosion resistance, and no scale. They are widely used in water supply, gas supply, liquid supply and other fields.

[0003] The assembly process of large-diameter steel-reinforced composite pipes presents numerous challenges. Traditional assembly methods often rely on manual labor, using simple tools such as sledgehammers, ropes, and tensioners. However, modern large-diameter steel-reinforced composite pipes are typically larger than 800mm in diameter. Manual dragging is not only extremely costly in terms of manpower and resources, but also makes it difficult to guarantee assembly accuracy, easily leading to problems such as misalignment of pipe ends and uneven gaps. These problems, once they occur, will severely affect the sealing of the pipe connections, causing media leakage, triggering safety accidents, and polluting the surrounding environment. Furthermore, they will reduce the pressure-bearing capacity of the pipeline system, potentially affecting the progress of the entire project, even shortening the service life of the pipeline, and increasing subsequent maintenance costs. Utility Model Content

[0004] To address the aforementioned issues, this utility model discloses a large-diameter steel-framed composite pipe socket assembly device. This device employs a hydraulic system to propel the assembly bidirectionally, enabling precise and rapid pipe connection. The interface welding is completed while the track remains under pressure, ensuring the stability and reliability of the connection quality, improving construction efficiency, and reducing labor costs and workload.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A large-diameter steel-reinforced composite pipe socket assembly device includes a base frame, a docking assembly, a propulsion block, and a hydraulic device. The base frame is a rectangular frame structure. The docking assembly includes a centering frame with two inwardly inclined circular tubes on it. Rollable rollers are mounted on the circular tubes. The two rollers are symmetrically arranged. Multiple centering frames are arranged laterally along the upper surface of the base frame. Two hydraulic devices are respectively located at both ends of the base frame. The telescopic rods of the hydraulic cylinders are connected to the propulsion blocks, and the outer side of the propulsion blocks is connected to straps.

[0006] As an improvement of this utility model, the base frame is made of H-beam steel.

[0007] As an improvement of this utility model, a bubble level is provided on the surface of the base frame.

[0008] As an improvement of this utility model, the upper surfaces of the multiple rollers are on the same horizontal plane.

[0009] As an improvement of this utility model, the propulsion block is elongated or cross-shaped.

[0010] As an improvement of this utility model, the push block is welded from channel steel, and the push block is connected to the front end of the telescopic rod of the hydraulic cylinder by a thread.

[0011] The beneficial effects of this utility model are as follows: The present invention discloses a socket assembly device for large-diameter steel-reinforced composite pipes. First, the base frame is leveled and securely fixed. Then, the spacing of the centering frame is adjusted according to the length of the pipes to be assembled. Next, the two pipe sections to be assembled are suspended on rollers, with the push block attached to the outer end of the pipe. A strap is tied to the outside of the push block, and the telescopic rod of the hydraulic cylinder connects to the push block, thus pushing the pipes towards the center, connecting the two ends of the pipes together.

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0017] As shown in the figure, the large-diameter steel-framed composite pipe socket assembly device of this utility model includes a base frame 1, a docking assembly 2, a push block 3, and a hydraulic device 4. The base frame 1 is a rectangular frame structure. The docking assembly 2 includes a centering frame 5. The centering frame 5 is provided with two inwardly inclined circular tubes 6. The circular tubes 6 are provided with rolling rollers 7. The two rollers 7 are symmetrically arranged. Multiple centering frames 5 are arranged laterally along the upper surface of the base frame 1 (installed on the upper surface of the base frame 1 by bolts). Two hydraulic devices 4 are respectively located at both ends of the base frame 1. The telescopic rod of the hydraulic cylinder is connected to the push block 3, and the outer side of the push block 3 is connected to the strap 8.

[0018] The large-diameter steel-reinforced composite pipe socket assembly device of this utility model is used by first leveling and firmly fixing the base frame 1, then adjusting the spacing of the centering frame 5 according to the length of the pipes 10 to be assembled, and then suspending the two sections of pipes 10 to be assembled on the roller 7, with the push block 3 attached to the outer end of the pipe 10. Figure 3 As shown, the strap 8 is tied to the outside of the push block 3. The telescopic rod of the hydraulic cylinder is connected to the push block 3, thereby pushing the pipe 10 towards the middle, and finally connecting the two pipes together. The weld joint is still under pressure during the welding process until the welding is completed.

[0019] The large-diameter steel-framed composite pipes described in this utility model have diameters greater than 800mm, are large in volume and heavy in weight, so the base frame 1 must be stable. The base frame of this utility model is made of H100×100 H-beams, which is stable and does not deform. A docking assembly 2 is set every 300mm on both sides of the longitudinal direction of the base frame 1. The two rollers 7 on the docking assembly 2 are symmetrically arranged, forming a group with a 90° V-shaped angle between them. The upper surfaces of multiple rollers 7 are on the same horizontal plane, which precisely constrains and controls the axial, radial and angular dimensions of the pipe. On the one hand, it ensures that the two pipes to be assembled can be automatically aligned and remain coaxial when moving back and forth. On the other hand, when the hydraulic device 4 pushes the pipe forward to the assembly, the rotation of the rollers 7 can reduce frictional resistance and move forward smoothly.

[0020] If a misalignment is found between the two pipes during the insertion process, the extension rod of the hydraulic cylinder is retracted, and the binding strap 8 is used to pull the pipe 10 back a certain distance. After checking that the roller is correct, the push block 3 is pushed again, thereby pushing the pipe 10 closer to the center, and finally completing the insertion work.

[0021] Because the pipe has a large diameter, the push block 3 of this utility model is long or cross-shaped. The push block 3 is welded from channel steel. When pushing, it can distribute the force to the entire end face of the pipe, so that the force is evenly distributed. The outer side of the push block 3 is connected to the strap 8. The hydraulic cylinder can push the pipe forward through the push block 3. When retracting, the pipe can only be pulled backward by the strap 8 (the forward and backward distance does not exceed 200mm. The strap 8 is located between the two sets of docking components 2. The strap 8 will not contact the roller 7 when the pipe moves).

[0022] The push block 3 is connected to the front end of the telescopic rod of the hydraulic cylinder by a thread, which facilitates disassembly.

[0023] The hydraulic device 4 described in this utility model mainly includes components such as a hydraulic pump station, a hydraulic cylinder, a control valve group, and high-pressure oil pipes; there are two sets of hydraulic devices 4, which are respectively installed at both ends of the base frame 1.

[0024] The binding strap 8 described in this utility model is an acid and alkali resistant fiber braided strap, which protects the outer surface of the steel skeleton composite pipe and will not damage the outer surface of the pipe.

[0025] In order to enable the two pipes to automatically align and remain coaxial when moving back and forth, this utility model is equipped with a bubble level 9 on the surface of the base frame 1 to ensure that the base frame 1 is in a horizontal state, so that the two pipes can be smoothly inserted.

[0026] The large-diameter steel-reinforced composite pipe socket assembly device described in this utility model enables precise and rapid pipe connection, reducing the insertion time by 80% compared to manual hoisting, thereby saving significant construction costs and shortening the pipeline construction cycle. This method not only requires less investment but also features a simple process and high construction efficiency, making it worthy of widespread adoption.

[0027] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
