[0002] HDPE wound reinforced pipe is a thermoformed high-density polyethylene wound structured-wall pipe, which uses high-density polyethylene resin as the main material and adopts a thermoforming winding process to make a special structured-wall pipe with high external pressure resistance using a polypropylene single-wall corrugated pipe as the support structure.

[0031] Working principle and advantages of the present invention: When the wire laying device for preparing wear-resistant HDPE winding reinforced pipes is in use, the working process is as follows:

[0032] As Figure 1 and Figure 3 shown, after fixing the HDPE winding reinforced pipe on the workbench 20, then sleeving the electrofusion wire ring from bottom to top on the convex platform 34. When the upper edge of the electrofusion wire ring abuts against the spherical end of the top pin 36, the top pin 36 slides into the groove 35 and compresses the third spring 37, so that the third spring 37 obtains a restoring force. And under the restoring force of the third spring 37, the top pin 36 plays a role in pressing the electrofusion wire ring, thereby playing a role in pre-clamping the electrofusion wire ring and preventing the electrofusion wire ring from falling off.

[0033] After the electric fuse ring is installed, start the cylinder 2 to work so that the cylinder 2 extends its piston rod and drives the first pressing plate 3 to move downward, making the first pressing plate 3 contact the lifting plate 5 and apply a downward pressure on it, causing the lifting plate 5 to drive the pressure rod 6 to move downward. As a result, the pressure rod 6 drives the boss 34 and the electric fuse ring on it to move downward through the hanging plate 13. That is, the electric fuse ring is pressed onto the inner wall of the socket of the HDPE wound and reinforced pipe blank through the hanging plate 13. While the pressure rod 6 moves downward, the first spring 11 is stretched by the annular projection 12, causing the first spring 11 to obtain an upward restoring force.

[0034] As described above, during the downward movement of the hanging plate 13, a pulling force is applied to the corresponding clamping arm 14 through the fourth connecting rod 15, causing the clamping arm to rotate towards the direction close to the pressure rod 6. And the clamping arm 14 drives the sliding rod 16 and the clamping plate 19 to approach the outer wall of the HDPE wound and reinforced pipe through the sleeve 17. When the clamping plate 19 abuts against the outer wall of the HDPE wound and reinforced pipe, the sleeve 17 compresses the second spring 18, causing the second spring 18 to obtain a restoring force, and the second spring 18 exerts a reaction force on the sleeve 17. If the pressure rod 6 and the HDPE wound and reinforced pipe are not on the same central axis position, at this time, the forces on each second spring 18 are not uniform. The second spring 18 with a greater force exerts a greater reaction force on the corresponding sleeve 17, causing the sleeve 17 to drive the circular plate 10 to move in the direction corresponding to this clamping arm 14 through the clamping arm 14 and the sliding sleeve 7. Furthermore, each second spring 18 is in a state of equal force, so that the pressure rod 6 and the HDPE wound and reinforced pipe are on the same central axis position. Furthermore, the electric fuse ring and the HDPE wound and reinforced pipe are on the same central axis position, avoiding deviation in wire laying and improving the wire laying accuracy.

[0035] While the lifting plate 5 moves downward, it drives the piston plate 23 to move downward in the pump cylinder 22 through the first push-pull rod 21. As a result, the piston plate 23 exerts a compressive force on the oil in the pump cylinder 22. Since the conduction direction of the one-way valve 24 points to the inside of the pump cylinder 22, this compressive force transports the oil in the pump cylinder 22 to the inside of the sliding cylinder 28 through the second liquid pipe 27, increasing the pressure inside the sliding cylinder 28 and causing the sliding plate 31 to move downward. Thus, the sliding plate 31 drives the second pressing plate 33 to move downward through the second push-pull rod 32. Furthermore, the second pressing plate 33 drives each second connecting rod 42 to move downward. Since the second connecting rod 42, the third connecting rod 43, and the two first connecting rods 39 form a parallel four-bar linkage mechanism, the third connecting rod 43 stretches the fourth spring 44 outward and makes it obtain a restoring force. At the same time, the third connecting rod 43 clamps the electric fuse ring and keeps the electric fuse ring from deforming inward, thus ensuring the integrity of the electric fuse ring when it is pressed onto the inner wall of the socket of the HDPE wound and reinforced pipe blank and improving the wire laying effect.

[0036] When the hydraulic pressure in the sliding cylinder 28 is higher than the set value of the pressure relief valve 29, the excess oil flows back into the oil storage box through the return pipe. After the wire laying is completed, the cylinder 2 is started to reset, and the pressing plate 1 moves upward, without applying pressure to the lifting plate 5. Thus, under the restoring force of the first spring 11, the pressing rod 6 drives the lifting plate 5 and the hanging plate 13 to move upward and reset. Since the electric fuse coil is buried on the inner wall of the socket of the HDPE winding reinforced pipe blank, when the hanging plate 13 moves upward and resets, the top pin 36 is disengaged from and does not contact the electric fuse coil. At this time, under the restoring force of the third spring 37, the top pin 36 moves outward and resets to pre-clamp the next electric fuse coil.

[0037] During the upward movement and reset of the hanging plate 13, the fourth connecting rod 15 exerts a thrust on the corresponding clamping arm 14, causing the clamping arm to rotate away from the pressing rod 6. And the clamping arm 14 drives the sliding rod 16 and the clamping plate 19 away from the outer wall of the HDPE winding reinforced pipe through the sleeve 17. When the clamping plate 19 is disengaged from and does not contact the outer wall of the HDPE winding reinforced pipe, the sliding rod 16 resets under the restoring force of the second spring 18.

[0038] While the lifting plate 5 moves upward, it drives the piston plate 23 to move upward in the pump cylinder 22 through the first push-pull rod 21. Thus, the piston plate 23 exerts a suction force on the oil in the pump cylinder 22. Since the conduction direction of the one-way valve 24 points to the inside of the pump cylinder 22, this suction force sucks the oil in the sliding cylinder 28 and the oil storage box into the pump cylinder 22 through the second liquid pipe 27 and the first liquid pipe 25, reducing the pressure in the sliding cylinder 28 and causing the sliding plate 31 to move upward and reset without applying a downward pressure on each second connecting rod 42. Thus, under the restoring force of the fourth spring 44, the third connecting rod 43 resets and moves away from the electric fuse coil, ensuring that the third connecting rod 43 does not pull out the electric fuse coil when moving upward, thereby completing the wire laying of the HDPE winding reinforced pipe.
