Abstract

The application discloses a spliced cement pipe lining structure and a mounting method thereof. The cement pipe lining structure comprises a plurality of spliced plates which are connected with each other, and a reinforcing strip is fixedly connected to the surface of the spliced plate and is used for being embedded into the inner surface of the cement pipe. The cement pipe lining is composed of a plurality of arc-shaped spliced plates which are connected with each other. The cement pipe lining is produced by taking the spliced plate as a production unit for injection molding and extrusion in the early stage of production. Compared with directly extruding an integral cement pipe lining with a large area, the cement pipe lining can improve the yield rate, and the area occupied in the later transportation is small and easy to transport. In addition, the reinforcing strip is provided on the surface of the spliced plate in a protruding mode. When the cement pipe is manufactured, the reinforcing strip can be pre-embedded into the cement pipe, so that the connection relationship can be strengthened. In addition, the spliced plates can be quickly assembled by using the buckles and the limiting blocks provided on the spliced plates, and the contact area with the inner wall of the cement pipe can be increased, and the stability of the connection can be strengthened.

Description

Spliced ​​Cement Pipe Lining Structure and Installation Method Technical Field

[0001] This invention relates to the field of cement pipe lining technology, specifically to a spliced ​​cement pipe lining structure and its installation method. Background Technology

[0002] Cement pipe lining is a type of pipe where the outer shell is made of steel or a rigid structure, and the inner lining is made of wear-resistant, corrosion-resistant, and high-temperature-resistant plastic or other materials. Through the physical and chemical properties of the materials themselves, the effects of the pipeline transported medium on the external structure, such as impact and corrosion, are reduced, which greatly extends the service life of the pipeline and reduces the cost for users.

[0003] Currently, cement pipe liners are mostly integrally molded. However, due to the large area extruded during the one-time extrusion process, defects are easily produced. Once defects occur, the extruded cement pipe liner cannot be used. Furthermore, cement pipe liners that are directly extruded into the pipe shape occupy a large space during transportation, making transportation inconvenient. Moreover, the surface of the current liner is smooth, and adhesives are added during the cement pipe manufacturing process to increase the adhesion between the liner and the cement pipe. However, even with this method of connection, there is still a possibility that the cement pipe liner may detach. Summary of the Invention

[0004] The purpose of this invention is to provide a spliced ​​cement pipe lining structure and its installation method, wherein the cement pipe lining is composed of several arc-shaped splicing plates connected to each other. This type of cement pipe lining structure provides convenience in both the early stage of production and the later stage of transportation.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The spliced ​​cement pipe lining structure includes several interconnected splicing plates. Reinforcing strips are fixedly connected to the surface of the splicing plates. The reinforcing strips are embedded in the inner surface of the cement pipe. The cross-section of the reinforcing strips is T-shaped. A buckle is provided on one side of the splicing plate surface. The buckle is U-shaped. A limiting block is provided on the surface of the splicing plate. The cross-section of the limiting block is arrow-shaped, and the outer surface of the limiting block is adapted to the inner surface of the buckle.

[0007] As a further aspect of the present invention: one end face of the splicing plate is a sealing contact portion, and the other end face of the splicing plate is a sealing mating portion, wherein the surface of the sealing contact portion is in contact with the surface of the sealing mating portion.

[0008] As a further aspect of the present invention: both sides of the inner surface of the splicing plate are provided with connecting blocks and connecting plates. The connecting blocks are used to wrap the connecting plates. A through hole is opened on one side of the connecting blocks. A connecting rod for limiting the position of the connecting plate is slidably connected to the inner surface of the through hole. A connecting through hole adapted to the connecting rod is opened on the upper part of the connecting plate. A connecting spring is sleeved on the surface of the connecting rod, wherein one end of the connecting spring is fixedly connected to the surface of the connecting blocks.

[0009] As a further aspect of the present invention: the end face of the connecting rod is hemispherical, and both sides of the connecting plate are provided with gradient portions, which are used to push the connecting rod to slide on the inner surface of the through hole.

[0010] This invention also discloses an installation method for a spliced ​​cement pipe lining structure, specifically including the following steps:

[0011] Step 1: Insert the first splicing plate into the installation equipment. After rotating the installation equipment, insert the second splicing plate into the installation equipment along one side of the first splicing plate. At this time, the sealing contact part contacts the surface of the sealing mating part, and the limiting block is inserted into the buckle, thereby connecting them.

[0012] Step 2: Repeat Step 1 to connect several splicing plates in sequence, forming a closed ring to create the inner lining of the cement pipe.

[0013] Step 3: Splice the cement pipe lining at the other end of the installation equipment, and use the installation equipment to rotate the connecting plate on one side of the cement pipe lining into the inside of the connecting clip block on the other side of the cement pipe lining, and insert the connecting rod into the inside of the connecting through hole, thereby connecting the two cement pipe linings to each other.

[0014] As a further embodiment of the present invention: the installation device includes a base located on the ground, a support ring symmetrically arranged on the top of the base, and a drive ring symmetrically arranged on both sides of the top of the splicing plate. The inner surfaces of the support ring and the drive ring are provided with a rotating sleeve that can rotate. A plurality of limiting blocks are fixedly connected to the inner surface of the rotating sleeve. The limiting blocks are used to limit the reinforcing strip.

[0015] As a further embodiment of the present invention: a drive motor is provided on both sides of the top of the base, a drive gear is fixedly connected to the output end of the drive motor, a side slot is opened on the surface of the drive ring, and a number of gear teeth are provided on the outer surface of the inner rotating sleeve of the drive ring, and the gear teeth are meshed with the drive gear.

[0016] As a further aspect of the present invention, the method of using the installation equipment is as follows: First, the reinforcing strip on the splicing plate is inserted into the corresponding limiting block, thereby connecting several splicing plates. The cement pipe liner is installed inside a set of support rings and drive rings. Similarly, the cement pipe liner is installed inside another set of support rings and drive rings. At this time, the cement pipe liners on both sides are pushed so that the end faces of the two cement pipe liners come into contact, and the connecting blocks and connecting plates on the two cement pipe liners are in an interlaced state. Then, the drive motors on both sides are started to rotate in opposite directions, thereby causing the drive gear to rotate. By utilizing the meshing relationship between the gear teeth and the drive gear, the rotating sleeve inside the drive ring is further driven to rotate, thereby causing the cement pipe liner to rotate, so that the connecting blocks and connecting plates are connected, thereby connecting the two cement pipe liners.

[0017] The beneficial effects of this invention are:

[0018] (1) The cement pipe liner in this invention is composed of several arc-shaped splicing plates connected to each other. In the early stage of production, the splicing plates are used as production units for injection molding and extrusion. Compared with the one-piece cement pipe liner with a larger area directly extruded, the yield rate can be improved. In the later stage of transportation, the area occupied is smaller and easier to transport. Moreover, by setting the raised reinforcing strip on the surface of the splicing plate, the reinforcing strip can be pre-embedded in the interior of the cement pipe during the manufacturing of the cement pipe, thereby strengthening its connection. Furthermore, by using the buckles and limiting blocks set on the splicing plate, several splicing plates can be quickly assembled. In addition, the contact area with the inner wall of the cement pipe can be increased, and the stability of the connection can be strengthened.

[0019] (2) In this invention, by extending a sealing contact part and a sealing mating part on the surface of the splicing plate, when the two splicing plates are connected to each other, the connection point of the two splicing plates can be sealed by surface contact to prevent gaps from appearing between the two splicing plates. At the same time, connecting blocks and connecting plates are provided on both ends of the splicing plate. Using the connecting rod and connecting spring on the connecting block, the connecting rod can be inserted into the connecting through hole on the connecting plate, thereby connecting the two spliced ​​cement pipe liners. The connection in this way is not only faster but also more convenient to operate, and it can also improve the applicability of the cement pipe liner.

[0020] (3) In this invention, the reinforcing strip can be limited by the limiting block in the installation equipment, and with the rotating sleeve that can rotate, when splicing the cement pipe lining, the splicing plate only needs to be inserted into the inside of the drive ring and the support ring, so that the reinforcing strip is in the limiting block, thereby completing the quick connection of the splicing plate. Moreover, after the cement pipe lining is spliced, the connecting sleeve in the two drive rings rotates, so that the connecting block rotates into the corresponding connecting plate, thereby enabling the two cement pipe linings to be quickly connected, further improving its practicality.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please refer to Figures 1-5. The present invention is a spliced ​​cement pipe lining structure, including several interconnected splicing plates 1. A reinforcing strip 2 is fixedly connected to the surface of the splicing plate 1. The reinforcing strip 2 is used to increase the contact area with the inner wall of the cement pipe by embedding it into the inner surface of the cement pipe. The cross-section of the reinforcing strip 2 is set in a "T" shape, thereby enhancing the stability of the connection between the cement pipe and the splicing plate 1 when the cement pipe is poured. A buckle 3 is provided on one side of the surface of the splicing plate 1. The buckle 3 is set in a concave shape. A limiting block 4 is provided on the surface of the splicing plate 1. The cross-section of the limiting block 4 is set in an "arrow" shape. The outer surface of the limiting block 4 is adapted to the inner surface of the buckle 3. Moreover, the arrow-shaped limiting block 4 can be quickly inserted into the buckle 3. The buckle 3 can also be deformed by pressing, thereby inserting the limiting block 4 into the inside of the buckle 3.

[0030] One end face of the splicing plate 1 is a sealing contact part 5, and the other end face of the splicing plate 1 is a sealing mating part 6. The surface of the sealing contact part 5 is in contact with the surface of the sealing mating part 6, which can avoid the phenomenon of leakage during use due to large gaps at the connection caused by production errors.

[0031] To enable the two cement pipe linings to connect to each other, connecting blocks 7 and connecting plates 8 are provided on both sides of the inner surface of the splicing plate 1. The connecting blocks 7 are used to wrap the connecting plates 8. A through hole 12 is opened on one side of the connecting blocks 7. A connecting rod 10 that limits the position of the connecting plate 8 is slidably connected to the inner surface of the through hole 12. A connecting through hole 9 that matches the connecting rod 10 is opened on the upper part of the connecting plate 8. A connecting spring 13 is sleeved on the surface of the connecting rod 10. One end of the connecting spring 13 is fixedly connected to the surface of the connecting blocks 7. The end face of the connecting rod 10 is hemispherical. Both sides of the connecting plate 8 are provided with gradient parts 11. The gradient parts 11 are used to push the connecting rod 10 to slide on the inner surface of the through hole 12. When the connecting plate 8 slides into the interior of the connecting blocks 7, the gradient parts 11 can push the connecting rod 10 to slide in the through hole 12 so that the connecting rod 10 can be inserted into the interior of the connecting through hole 9.

[0032] This invention also discloses an installation method for a spliced ​​cement pipe lining structure, specifically including the following steps:

[0033] Step 1: Insert the first splicing plate 1 into the interior of the limiting block 22 in the installation equipment. Start the drive motor 18 to rotate, thereby driving the drive gear 19 to rotate. Utilize the meshing relationship between the gear teeth 21 and the drive gear 19 to drive the rotating sleeve 17 inside the drive ring 16 to rotate, further driving the splicing plate 1 to rotate. Then, insert the second splicing plate 1 into the interior of another set of limiting blocks 22 along one side of the first splicing plate 1. At this time, the sealing contact part 5 contacts the surface of the sealing mating part 6, and the limiting block 4 is inserted into the interior of the buckle 3, thereby connecting them to each other.

[0034] Step 2: Repeat Step 1 to connect several splicing plates 1 in sequence, forming a closed ring, thereby completing the installation of the cement pipe lining between a set of support rings 15 and drive rings 16.

[0035] Step 3: Splice the cement pipe linings within another set of support rings 15 and drive rings 16 in the installation equipment. Push the cement pipe linings on both sides to bring their end faces into contact, and place the connecting clips 7 and connecting plates 8 on the two cement pipe linings in an interlaced state. At this time, start the drive motors 18 on both sides to rotate in opposite directions, thereby causing the drive gear 19 to rotate. This will rotate the connecting plate 8 on one side of the cement pipe lining into the connecting clip 7 on the other side. The gradient part 11 on the connecting plate 8 will push the connecting rod 10 to slide on the inner surface of the through hole 12, further stretching the connecting spring 13 until the connecting rod 10 moves to one side of the connecting through hole 9. At this time, under the push of the connecting spring 13, the connecting rod 10 is inserted into the connecting through hole 9, thereby connecting the two cement pipe linings together.

[0036] The installation equipment includes a base 14 located on the ground. Support rings 15 are symmetrically arranged on the top of the base 14, and drive rings 16 are symmetrically arranged on both sides of the top of the splicing plate 1. Rotating sleeves 17 are provided on the inner surfaces of both the support rings 15 and the drive rings 16. Several limiting blocks 22 are fixedly connected to the inner surface of the rotating sleeves 17. The limiting blocks 22 are used to limit the reinforcing strips 2, thereby positioning the splicing plate 1. Drive motors 18 are provided on both sides of the top of the base 14. The output of the drive motors 18... A drive gear 19 is fixedly connected to the end. A side slot 20 is opened on the surface of the drive ring 16. Several gear teeth 21 are provided on the outer surface of the rotating sleeve 17 located inside the drive ring 16. The gear teeth 21 mesh with the drive gear 19. The rotation of the rotating sleeve 17 driven by this structure can not only quickly insert the splicing plate 1 into the interior of the installation equipment when splicing the plate 1, but also quickly connect the inner linings of the two cement pipes by simply inserting the splicing plate 1 into the interior of the installation equipment in one direction.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
