Technical Field
[0001] This invention relates to the field of plastic pipe processing technology, and in particular to a socket-type steel strip reinforced polyethylene spiral corrugated pipe assembly. Background Technology
[0002] Currently, the two ends of the socket-type steel-reinforced polyethylene spiral corrugated pipe are injection-molded with specially made polyethylene tubular connectors, one end being a socket and the other a spigot. This type of socket-type steel-reinforced polyethylene spiral corrugated pipe often uses the elastic deformation of a rubber ring fitted into the spigot groove to achieve a flexible sealing connection. However, after the steel-reinforced polyethylene spiral corrugated pipe is produced by injection molding, the installation of sealing rings is required. But since steel-reinforced polyethylene spiral corrugated pipes are usually large, the sealing rings used are also large-sized, requiring two or more people to complete the work. This increases labor costs, reduces construction efficiency, and affects the construction schedule. Summary of the Invention

The connecting shaft is connected to the drive unit.
[0010] Preferably, the end of the tensioning block away from the mounting plate has a protruding edge, and the end face of the tensioning block facing the fixing sleeve has a clamping block. The pipe opening of the socket-type steel strip reinforced polyethylene spiral corrugated pipe abuts against the clamping block, and the protruding edge rests on the outside of the pipe opening.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0025] A specific embodiment of the present invention provides a socket-type steel strip reinforced polyethylene spiral corrugated pipe assembly, combined with an attached... Figure 1 and attached Figure 2 As shown, it mainly includes a working platform 1, a mounting plate 2, a fixing sleeve 3, a tensioning block 4, a tensioning spindle 5, a push rod 6, and a drive unit 7, wherein:
[0026] The working platform 1 is the main support structure used to support the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17 and to set up other components;
[0027] Mounting plate 2 is set on the working platform 1. Mounting plate 2 is set vertically. Mounting plate 2 can be an L-shaped plate. One side of mounting plate 2 is connected to the lower working platform 1. Other components are set on the other side of mounting plate 2.
[0028] The fixing sleeve 3 is horizontally set on the mounting plate 2. Specifically, the fixing sleeve 3 is set perpendicular to the vertical edge of the mounting plate 2. The fixing sleeve 3 can be a cylindrical body or a prismatic body, and is set on the mounting plate 2 with the center line of the fixing sleeve 3 perpendicular to the vertical edge of the mounting plate 2.
[0029] The tensioning block 4 is movably set outside the fixed sleeve 3. The number of tensioning blocks 4 needs to be set to multiple, and the multiple tensioning blocks 4 are evenly distributed along the circumference of the fixed sleeve 3. The multiple tensioning blocks 4 surround the fixed sleeve 3 to form the entire tensioning body. The sealing ring 10 is sleeved on the outside of this sealing body. A top block 8 is also provided on the end face of the tensioning block 4 facing the fixed sleeve 3. The top block 8 passes through the outer wall of the fixed sleeve 3 and extends into the interior of the fixed sleeve 3. The top block 8 can contact the tensioning spindle 5 inside the fixed sleeve 3.
[0030] The tensioning mandrel 5 is horizontally positioned and movably connected to the fixed sleeve 3, allowing the tensioning mandrel 5 to translate horizontally. At least a portion of the tensioning mandrel 5 is located inside the fixed sleeve 3, and a part of the tensioning mandrel 5 inside the fixed sleeve 3 is used to push the top block 8. Specifically, the outer wall surface 9 of the portion of the tensioning mandrel 5 located inside the fixed sleeve 3 needs to be designed as an inclined surface. During the translation of the tensioning mandrel 5, the top block 8 and the outer wall surface 9 are in constant contact, and the inclined plane can push the top block 8 to drive the tensioning block 4 to move away from the fixed sleeve 3. In this way, during the movement of the tensioning mandrel 5, multiple tensioning blocks 4 move away from the fixed sleeve 3 in a star-shaped manner, thereby opening the sealing ring 10.
[0031] The push rod 6 is located on the outside of the tensioning block 4. Both the tensioning spindle 5 and the push rod 6 are connected to the drive unit 7. The drive unit 7 can drive the push rod 6 to move back and forth in the horizontal direction. The push rod 6 can push out the sealing ring 10 that has opened on the outside of the tensioning block 4.
[0032] The above-described structure, which involves opening the sealing ring 10 and then pushing it down using the push rod 6, allows for the installation of the sealing ring 10. Furthermore, since commonly used socket-type steel-reinforced polyethylene spiral corrugated pipes are large-volume pipes, they also utilize large-volume sealing rings 10. Therefore, a working platform supports the socket-type steel-reinforced polyethylene spiral corrugated pipe, and the sealing ring 10 is installed horizontally. A single person can complete the installation of the sealing ring 10, thus reducing the waste of human resources. Mechanized installation saves manpower compared to manual installation, allowing for uninterrupted work and improving construction efficiency.
[0033] This application also requires a limiting connector 11 to connect the tensioning block 4 and the fixing sleeve 3. The limiting connector 11 passes through the tensioning block 4 and connects to the fixing sleeve 3. The tensioning block 4 can move along the axial direction of the limiting connector 11. (See attached diagram for details.) Figure 1As shown, the limiting connector 11 can be a bolt with an external thread at the head and a smooth shank at the shank. A through hole is provided on the tensioning block 4, and a threaded hole is provided on the corresponding fixing sleeve 3. The bolt passes through the through hole and is threaded into the threaded hole. The length of the bolt is set to be longer than the thickness of the tensioning block 4 and the fixing sleeve 3, allowing for a certain amount of movement between the tensioning block 4 and the fixing sleeve 3. The tensioning block 4 can move along the axial direction of the bolt, and the number of these limiting connectors 11 can be increased along the length direction of the tensioning block 4 (see attached diagram). Figure 1 Two or more limit connectors (horizontal) are provided to provide a good limiting connection. Of course, the limit connector 11 can also be configured in other ways according to the actual situation, so that the tensioning block 4 and the fixing sleeve 3 can be connected in a similar way to the above-mentioned limiting method.
[0034] In a specific embodiment of this application, a reset member 12 is also provided. The reset member 12 is disposed on the tensioning block 4 and is used to push the tensioning block 4 toward the fixed sleeve 3, so that the tensioning block 4, which has been opened by the tensioning spindle 5, can return to its original position. Specifically, the reset member 12 can be an elastic ring. The reset member 12 is sleeved on the outside of all the tensioning blocks 4. Grooves are provided on the outer surface of all the tensioning blocks 4 away from the fixed sleeve 3. The grooves on all the tensioning blocks 4 are connected in a ring shape. By sleeved multiple tensioning blocks 4, the retraction action of the reset member 12 applies a force toward the fixed sleeve 3 to the tensioning blocks 4. The reset member 12 can also be disposed between the tensioning block 4 and the fixed sleeve 3. The reset member 12 can be a spring, and the tension force of the spring pulls the tensioning block 4 toward the fixed sleeve 3, thereby achieving the purpose of automatic retraction. Retraction is necessary for the subsequent filling of the sealing ring 10. After all the tensioning blocks 4 have retracted, the sealing ring 10 can be easily sleeved on the outside of the tensioning blocks 4.
[0035] The tensioning mandrel 5 in this application includes a push shaft 13 and a connecting shaft 14. The push shaft 13 is located inside the fixed sleeve 3 and is mainly used to push the tensioning block 4. The connecting shaft 14 passes through the mounting plate 2 and extends into the fixed sleeve 3 to connect with the tail end of the push shaft 13. The connecting shaft 14 is used to connect to the external drive unit 7 and transmits the force transmitted from the drive unit 7 through the connecting shaft 14. A through hole is provided in the mounting plate 2. The connecting shaft 14 can be a cylindrical shaft. A linear bearing is provided in the through hole, and the connecting shaft 14 passes through the linear bearing. The cross-sectional dimension of the push shaft 13 in this application, perpendicular to the center line from the head end to the tail end, first gradually increases and then remains constant, as detailed in the attached figure. Figure 1As shown, the push shaft 13 consists of a frustum or prismatic structure in the front half near the head end and a cylindrical or prismatic structure in the rear half near the tail end. When the front half is frustum-shaped, the rear half is cylindrical; when the front half is prismatic, the rear half is prismatic. This ensures that the front half has an inclined outer surface, thus guaranteeing that a thrust is gradually applied to the top block 8 during the translation of the push shaft 13. When the top block 8 moves relative to the push shaft 13 to the rear half, no further expansion is needed; only the sealing ring needs to be installed. 10 can be pushed down. Because this application uses the same drive unit 7 to linearly drive the tensioning mandrel 5 and the push rod 6 at the same time, the push rod 6 only contacts the sealing ring 10 after the tensioning mandrel 5 has fully opened the sealing ring 10, and then pushes down the sealing ring 10. For this reason, the length of the push rod 6 needs to be set to be less than the length of the tensioning mandrel 5. The tensioning mandrel 5 and the push rod 6 are both set on the same drive plate, and the drive plate is connected to the drive unit 7. The drive unit 7 can be a ball screw motor to achieve linear drive or an electric push rod, etc., for drive.
[0036] In a specific embodiment of this application, a protruding edge 15 is extended from the end of the tensioning block 4 away from the mounting plate 2, and a retaining block 16 is provided on the end face of the tensioning block 4 facing the fixing sleeve 3. The retaining block 16 is close to the protruding edge 15. When the working platform 1 lifts the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17 to be coaxial with the center line of the fixing sleeve 3, the pipe opening of the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17 can abut against the retaining block 16, and the protruding edge 15 rests on the outside of the pipe opening. This can ensure that the sealing ring 10 can be smoothly pushed into the mounting groove on the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17.
[0037] In order to ensure that the sealing ring 10 is pushed down with even force, multiple push rods 6 are provided. The number of push rods 6 is the same as the number of tensioning blocks 4, and the push rods and tensioning blocks 4 are set in a one-to-one correspondence.
[0038] In one embodiment, the end of the top block 8 away from the tensioning block 4 is also set as an arc-shaped surface 18, for example, designed as a hemispherical structure, to ensure that the top block 8 can always smoothly contact the outer wall surface 9 of the tensioning mandrel 5.
[0039] It is worth noting that the outer surface of the tensioning block 4 can be designed as an arc shape, with the center line of the fixing sleeve 3 as the central axis. This allows all the tensioning blocks 4 to form a cylindrical ring after contraction.
[0040] In a specific embodiment of this application, the working platform 1 includes a base 19, a lifting frame 20, a support frame 21, a moving platform 22, a translation mechanism 23, and a lifting roller mechanism 24, in conjunction with the attached... Figure 4As shown, the base 19 is used to support the ground where it is placed. A lifting frame 20 is set on the top of the base 19, and a support frame 21 is set on the lifting frame 20. The support frame 21 can be raised and lowered by the lifting action of the lifting frame 20. The lifting frame 20 can be a hydraulic cylinder mechanism or a worm gear structure, etc., that can achieve the lifting action.
[0041] The movable platform 22 is slidably mounted above the support frame 21. A slide rail is provided above the support frame 21, and pulleys are provided at the bottom of the movable platform 22. The movable platform 22 is mounted on the support frame 21, and the pulleys are located inside the slide rail, thus enabling the movable platform 22 to move. The support frame 21 and the movable platform 22 are connected by a translation mechanism 23, which drives the parallel movement of the movable platform 22. The mounting plate 2 is mounted on the movable platform 22, so that the entire assembly is mounted on the movable platform 22. The movement of the movable platform 22 can drive the overall translation of the entire assembly. Specifically, the translation mechanism 23 includes a cylinder 26 and a connecting rod 27. The cylinder 26 is located below the support frame 21 and is connected to the bottom wall of the support frame 21. A slot 30 along the length of the cylinder 26 is provided on the support frame 21. The connecting rod 27 passes through the slot 30 and connects to the movable platform 22. Thus, the movable platform 22 can be moved by pushing the cylinder 26.
[0042] An extension 25 is also provided on the moving platform 22. The moving platform 22 is a large-area plate-shaped body, and the extension 25 is a square opening set on the entire plate. To ensure that the moving platform 22 will not collide with the lifting roller mechanism 24 after translation, a certain length of spare length is reserved for the extension 25. The lifting roller mechanism 24 is set on the support frame 21 corresponding to the extension 25. The lifting roller mechanism 24 can support and lift the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17 through its own lifting action and the top roller 29. Specifically, the lifting roller mechanism 24 includes a lifting cylinder 28 and a roller 29. The lifting cylinder 28 is set below the support frame 21. The lifting cylinder 28 passes through the support frame 21 and connects to the roller 29. The axis of the roller 29 is oriented in the same direction as the support frame 21. The centerline of the fixed sleeve 3 is parallel, and the lifting roller mechanism 24 is arranged in pairs. At least two sets of lifting roller mechanism 24 are arranged along the centerline of the fixed sleeve 3. The two sets of lifting roller mechanism 24 arranged in pairs can achieve stable support for the cylindrical socket-type steel strip reinforced polyethylene spiral corrugated pipe 17. At least two sets are arranged in the length direction. The large-volume socket-type steel strip reinforced polyethylene spiral corrugated pipe 17 is lifted by multiple lifting roller mechanisms 24 to a state where the axis of the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17 is coaxial with the centerline of the fixed sleeve 3. Then, the sliding action of the moving table 22 drives the sleeve mechanism to move to press against the socket-type steel strip reinforced polyethylene spiral corrugated pipe 17. Finally, the sealing ring 10 is pushed down by the push rod 6.
[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
