Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to a steel-reinforced polyethylene spiral corrugated pipe connection device. Background Technology

[0002] Steel-reinforced polyethylene spiral corrugated pipe (PE spiral corrugated pipe) is a pipe product that combines high-density polyethylene (PE) and steel strip materials. It is formed by molding steel strip coated with adhesive resin into a corrugated structure through a special process and then winding it with polyethylene material to form a whole double-walled spiral corrugated pipe. This pipe combines the high strength of steel with the flexibility, corrosion resistance, and wear resistance of polyethylene, and has excellent performance.

[0003] Steel-reinforced polyethylene spiral corrugated pipes are widely used in drainage, sewage and other fields due to their excellent performance. In practical engineering applications, the connection between pipes is the key link to ensure the normal operation of the entire pipeline system. Traditional steel-reinforced polyethylene spiral corrugated pipe connection devices are mostly fixed in size or have only a limited adjustment range when in use. They cannot adapt to steel-reinforced polyethylene spiral corrugated pipes with different outer diameter specifications, and cannot meet diverse engineering needs, thus lacking practicality. Therefore, it is necessary to redesign the steel-reinforced polyethylene spiral corrugated pipe connection device to address the above problems. Utility Model Content

[0024] This utility model provides a technical solution for a steel-reinforced polyethylene spiral corrugated pipe connection device:

[0025] Please see Figures 1-5A steel-reinforced polyethylene spiral corrugated pipe connecting device includes a base plate 1. Multiple support legs 2 are fixedly installed on the bottom wall of the base plate 1. Each support leg 2 has a support block 3 fixedly installed on its bottom wall. A bidirectional screw 5 is rotatably installed on the upper surface of the base plate 1 via a connecting frame 4. A motor 6 connected to the bidirectional screw 5 is fixedly installed on the outer wall of the connecting frame 4. Two moving blocks 8 are rotatably installed on the outer wall of the bidirectional screw 5 via a limiting mechanism. Placement plates 10 are fixedly installed on the upper surfaces of both moving blocks 8. Guide frames 12 are fixedly installed on both sides of each guide frame 12. Electric push rods 14 are fixedly installed on both outer walls of the guide frames 12 through an installation mechanism. Telescopic openings that cooperate with the telescopic ends of the electric push rods 14 are opened on both outer walls of the guide frames 12. A spring telescopic rod 16 is fixedly installed on the telescopic end of each electric push rod 14 through a connecting mechanism. A clamping plate 17 is fixedly installed on the telescopic end of each spring telescopic rod 16. A clamping protrusion 18 is fixedly installed on the inner wall of each clamping plate 17. Each clamping protrusion 18 has a conical cross section.

[0026] The limiting mechanism includes a limiting rod 7 fixedly installed inside the connecting frame 4, and the limiting rod 7 slides through the two moving blocks 8.

[0027] Furthermore, the setting of the limiting rod 7 effectively restricts the rotational freedom of the moving block 8, so that the moving block 8 can only move axially under the drive of the bidirectional screw 5, ensuring the stability and accuracy of the movement of the moving block 8, thereby ensuring the accuracy of the pipeline alignment process and avoiding pipeline misalignment caused by the rotation of the moving block.

[0028] The mounting mechanism includes a mounting frame 13 fixedly mounted on the outer wall of the guide frame 12, and an electric push rod 14 fixedly mounted on the inner wall of the mounting frame 13.

[0029] Furthermore, the mounting frame 13 provides a solid mounting base for the electric actuator 14, enhancing the stability of the electric actuator 14 during operation. At the same time, it provides a certain degree of protection for the electric actuator 14, preventing external factors from damaging the electric actuator 14, extending its service life, and ensuring that the electric actuator 14 can continuously and stably provide power for clamping operations.

[0030] The connecting mechanism includes a connecting plate 15 fixedly installed at the telescopic end of the electric push rod 14, and a spring telescopic rod 16 fixedly installed on the outer wall of the connecting plate 15.

[0031] Furthermore, the connecting plate 15, as a key component connecting the electric actuator 14 and the spring telescopic rod 16, can reliably transmit the extension force of the electric actuator 14, while providing a stable mounting surface for the spring telescopic rod 16, ensuring that the spring telescopic rod 16 can work stably under force, realizing coordinated action with the electric actuator 14, and improving the continuity and reliability of the clamping operation.

[0032] Two stabilizing rods 9 are fixedly installed inside the connecting frame 4, and both stabilizing rods 9 slide through the two moving blocks 8.

[0033] Furthermore, the stabilizing rod 9 and the limiting rod 7 work together to further enhance the stability of the moving block 8 during its movement, disperse the force on the moving block 8 during its movement, reduce the stress on the bidirectional screw 5 and the limiting rod 7, improve the stability and reliability of the entire device structure, and ensure that all components can operate stably during the pipeline connection process.

[0034] Both placement plates 10 have installation openings on their upper surfaces, and multiple guide rollers 11 are rotatably installed inside each of the two installation openings.

[0035] Furthermore, the guide roller 11 can greatly reduce the friction during pipe placement and adjustment. Operators can easily move the pipe on the placement plate 10, and conveniently and quickly adjust the position of the pipe so that the pipe can accurately reach the predetermined connection position, thereby improving the convenience and efficiency of pipe installation.

[0036] In practical use, the working principle of this utility model is as follows:

[0037] The base plate 1 can be stably placed by the cooperation of multiple support legs 2 and multiple support blocks 3 to ensure that the entire device remains stable during operation and avoids affecting the pipe connection accuracy due to shaking. When it is necessary to connect two steel strip reinforced polyethylene spiral corrugated pipes, the operator places the two pipes to be connected on two placement plates 10 respectively. The multiple guide rollers 11 rotatably installed on the placement plate 10 can reduce the friction between the pipe and the placement plate 10, so that the operator can easily adjust the position of the pipe and make the pipe approximately in the center of the guide frame 12.

[0038] Subsequently, the motor 6 on the outer wall of the connecting frame 4 is started. The power output shaft of the motor 6 drives the bidirectional screw 5 to rotate. Since the two threads on the outer wall of the bidirectional screw 5 rotate in opposite directions, and the two moving blocks 8 are screwed and rotated with the bidirectional screw 5 through the limiting mechanism, the moving blocks 8 cannot rotate around the bidirectional screw 5 under the restriction of the limiting rod 7, and can only move along the axial direction. Therefore, as the bidirectional screw 5 rotates, the two moving blocks 8 will move synchronously in opposite directions, thereby driving the placement plate 10, the guide frame 12 and the pipe placed on it to move, realizing the automatic alignment of the two pipes to be connected, ensuring that the axis of the pipe is on the same straight line, laying the foundation for subsequent connection operations.

[0039] After the pipe alignment is completed, the electric actuator 14 is activated. The electric actuator 14 is fixedly installed in the mounting frame 13 on the outer wall of the guide frame 12. Its telescopic end passes through the telescopic holes on both sides of the outer wall of the guide frame 12 and is connected to the spring telescopic rod 16 through the connecting plate 15. When the telescopic end of the electric actuator 14 extends, it pushes the spring telescopic rod 16 and the clamping plate 17 to move towards the pipe. When the clamping plate 17 contacts the outer wall of the pipe, the spring telescopic rod 16 will be compressed with further pushing. At this time, the conical clamping protrusion 18 on the inner wall of the clamping plate 17 will fit tightly against the pipe surface. The conical design allows the clamping protrusion 18 to automatically adjust the fitting angle according to the different outer diameters of the pipe. No matter what the outer diameter of the pipe is, it can achieve tight and stable clamping, effectively preventing the pipe from shifting during the connection process.

[0040] After the pipe is stably clamped, the corresponding connection process, such as hot melt connection or electrofusion connection, can be used to connect the two pipes. During the connection process, the limiting mechanism and stabilizing rod 9 of the device can continuously ensure the stability of the moving block 8 and avoid pipe misalignment due to external interference. After the connection is completed, first close the electric push rod 14 to retract its telescopic end, and the spring telescopic rod 16 restores its deformation, driving the clamping plate 17 to release the pipe. Then, turn off the motor 6 and remove the connected pipe from the placement plate 10. This completes the connection of a steel strip reinforced polyethylene spiral corrugated pipe.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
