[0002] Polyethylene composite pipes are widely used in all aspects of production and life, and have the characteristics of excellent corrosion resistance, no scaling, smoothness and low resistance.

[0003] With the increase in the scope of application, the pressure-bearing and heat-resistant properties of polyethylene composite pipes cannot meet the use requirements under high temperature and high pressure environments, and with the increase in the use time, the durable strength of the plastic of the polyethylene composite pipe itself will be greatly reduced. At the same time, polyethylene composite pipes are often piled together in large quantities when placed. Since the composite pipes are round, they are prone to displacement and slipping during stacking, which requires manual rearrangement, which is time-consuming and will also cause unnecessary losses due to slipping.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-7A multi-layer reinforced steel wire mesh skeleton polyethylene composite pipe comprises a composite pipe 1, the inner wall and the outer wall of the composite pipe 1 are polyethylene layers 2, a first steel wire mesh 3 is arranged inside the polyethylene layer 2, a second steel wire mesh 4 is arranged between the first steel wire mesh 3 and the inner wall of the composite pipe 1, a modified bonding resin is filled between the first steel wire mesh 3 and the second steel wire mesh 4, and stacking components 5 are arranged at both ends of the composite pipe 1. The composite pipe 1 is similar to the traditional polyethylene pipe in that the composite pipe 1 is still made of polyethylene material, which can ensure the anti-corrosion, anti-scaling and smooth and low-resistance characteristics of the composite pipe 1. In order to improve the compressive and high-temperature resistance of the composite pipe 1, the first steel wire mesh 3 and the second steel wire mesh 4 are used as the skeleton during production. The first steel wire mesh 3 and the second steel wire mesh 4 can effectively restrain the creep of the polyethylene material and increase the strength of the polyethylene material, thereby improving the compressive and high-temperature resistance of the composite pipe 1. In production, a modified adhesive resin is used to tightly connect the polyethylene layer 2 and the first steel wire mesh 3 and the second steel wire mesh 4, so that the composite pipe 1 can inherit the advantages of the polyethylene pipe and overcome its disadvantages. The stacking components 5 are installed at both ends of the composite pipe 1. When the composite pipes 1 are stacked, each composite pipe 1 can be evenly and orderly discharged by combining the stacking components 5. Since the stacking components 5 can be combined in pairs and limit each other, the composite pipe 1 can be effectively prevented from deviating or sliding, which can reduce the quality problems caused by external damage to the composite pipe 1 and prevent increased labor after sliding.

[0027] As a technical optimization solution of the utility model, the stacking assembly 5 includes a stacking block 6, which is a flat rectangular structure, with a through hole 7 in the center of the stacking block 6, a wedge block 8 fixedly connected to the bottom of the stacking block 6, a matching groove 9 at the top of the stacking block 6, and a connecting mechanism 10 arranged in the matching groove 9. The two ends of the composite pipe 1 are inserted into the through hole 7 for positioning the composite pipe 1, and the two stacking blocks 6 can be stacked through the cooperation of the wedge block 8 and the matching groove 9, and after the wedge block 8 is connected to the matching groove 9, the wedge block 8 can push the connecting mechanism 10 to slide out of the matching groove 9 to facilitate the stacking block 6 to connect with another stacking block 6 in the horizontal direction, and such a cycle can realize the connection of multiple stacking blocks 6 in pairs, so that multiple composite pipes 1 are stacked in an orderly manner without being easily offset and slipping.

[0028] As a technical optimization solution of the utility model, the connection mechanism 10 includes a wedge-shaped slider 101 and a first spring 12. The wedge-shaped slider 101 is slidably connected to one side of the matching groove 9, and the fixed block 11 is fixedly connected to the middle of the bottom end of the wedge-shaped slider 101. The first spring 12 is fixedly connected between one side of the fixed block 11 and one side of the inner wall of the matching groove 9. When a wedge-shaped block 8 of a stacking card block 6 is connected to the matching groove 9, the wedge-shaped block 8 pushes the wedge-shaped slider 101 and the fixed block 11 to slide along the matching groove 9 until the tail of the wedge-shaped slider 101 passes through the matching groove 9. At this time, the first spring 12 is compressed. In the idle state, the first spring 12 resets and pushes the fixed block 11 and the wedge-shaped slider 101 to be retracted into the matching groove 9.

[0029] As a technical optimization solution of the utility model, a connecting groove 13 is provided on the side wall of the top of the stacking block 6 away from the wedge-shaped slider 101. The size of the connecting groove 13 matches the tail of the wedge-shaped slider 101, and a locking mechanism 14 is provided in the connecting groove 13. When placing the horizontal composite pipe 1, the connecting groove 13 on the horizontal stacking block 6 can be aligned with the tail of the wedge-shaped slider 101 that has passed through the matching groove 9. At this time, the wedge-shaped slider 101 in the stacking block 6 of the second layer is still accommodated in the matching groove 9, so it does not affect the stacking of the second layer of stacking blocks 6. When stacking the third layer of stacking blocks 6, the wedge-shaped block 8 of the third layer of stacking blocks 6 can be used to connect the wedge-shaped slider 101 of the second layer to the connecting groove 13. In this way, multi-layer stacking can be realized by a cycle. The locking mechanism 14 can lock the two horizontal stacking blocks 6 to prevent the stacking blocks 6 of the bottom layer from sliding when stacking high-layer composite pipes 1.

[0030] As a technical optimization solution of the utility model, the locking mechanism 14 includes a connecting rod 15 and a ball head 17. A connecting hole is provided on one side of the connecting groove 13, and the connecting rod 15 is slidably connected in the connecting hole. The ball head 17 is connected to one end of the connecting rod 15 close to the connecting groove 13, and the other end of the connecting rod 15 is fixedly connected to a limit block 18, which is located outside the stacking block 6. When the tail of the wedge-shaped slider 101 is connected to the connecting groove 13, the tail of the wedge-shaped slider 101 first abuts against the ball head 17 and then pushes the ball head 17 and the connecting rod 15 to slide outward along the connecting hole until the ball head 17 slides into the groove 19 to achieve the locking of the two stacking blocks 6.

[0031] As a technical optimization solution of the utility model, a groove 19 is provided on the side wall of the rear end of the wedge-shaped slider 101, and the groove 19 is adapted to the ball head 17. A second spring 16 sleeved on the connecting rod 15 is fixedly connected between the ball head 17 and the stop block 18. The second spring 16 is used to push the ball head 17 into the groove 19. When unlocking, the stop block 18 can be pulled to pull the ball head 17 out of the groove 19.

[0032] As a technical optimization solution of the utility model, an adjustment groove is provided on one side of the top of the stacking block 6, and an adjustment block 20 is slidably connected in the adjustment groove. One side of the adjustment block 20 is an arc-shaped structure, and a plurality of slots 21 are symmetrically provided on the outer side wall of the adjustment groove. When stacking composite pipes 1 of different diameters, the position of the adjustment block 20 can be adjusted so that the arc-shaped structure of the adjustment block 20 abuts against the top of the composite pipe 1 and the block at the tail of the adjustment block 20 is connected to the slot 21 for fixation, which can meet the stacking requirements of composite pipes 1 of different diameters.

[0033] When the utility model is in use, the first steel wire mesh 3 and the second steel wire mesh 4 are used as the skeleton during production, and the polyethylene layer 2 and the first steel wire mesh 3 and the second steel wire mesh 4 are tightly connected together by using a modified adhesive resin to form a composite pipe 1. When stacking, both ends of the composite pipe 1 are inserted into the through hole 7, and the two stacking blocks 6 can be stacked through the cooperation of the wedge block 8 and the matching groove 9. After the wedge block 8 is inserted into the matching groove 9, the wedge block 8 pushes the wedge slider 101 and the fixed block 11 to slide along the matching groove 9 until the tail of the wedge slider 101 passes through the matching groove 9. At this time, the first spring 12 is compressed. This is to stack the first layer of composite pipes 1 in the horizontal direction. The connecting groove 13 on the stacking block 6 in the horizontal direction is aligned with the tail of the wedge slider 101 that has passed through the matching groove 9. When the wedge slider 101 When the tail is connected to the connecting groove 13, the tail of the wedge-shaped slider 101 first abuts the ball head 17 and then pushes the ball head 17 and the connecting rod 15 to slide outward along the connecting hole until the ball head 17 slides into the groove 19 to achieve the locking of the two stacking blocks 6. At this time, the wedge-shaped slider 101 in the stacking block 6 of the second layer is still received in the matching groove 9, so it does not affect the stacking of the second layer of stacking blocks 6. When stacking the third layer of stacking blocks 6, the wedge-shaped slider 101 of the second layer can be connected to the connecting groove 13 through the wedge block 8 of the third layer of stacking blocks 6. Such a cycle can realize multi-layer stacking. When stacking composite pipes 1 of different diameters, the position of the adjusting block 20 can be adjusted so that the arc structure of the adjusting block 20 abuts against the top of the composite pipe 1 and the block at the tail of the adjusting block 20 is connected to the slot 21 for fixation.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
