Description

Technical Field

[0001] This application belongs to the technical field of pipeline positioning equipment, specifically a positioning device for pre-embedded concrete pipelines. Background Technology

[0002] When installing sewage, tap water, and urban water pipes, the pipes are usually buried in the soil. During construction, a foundation pit is dug in the ground, and then several pipes are placed inside the foundation pit and backfilled with soil.

[0003] Referring to CN215488051U, a pre-embedded pipe positioning device includes multiple positioning mechanisms. Each positioning mechanism includes a base plate abutting against the bottom of a foundation pit. The base plate is provided with a fixing seat for installing the pipe. The base plate also includes an adjustment assembly, which includes a drive screw, two sliders, and two push rods. The drive screw passes through and is rotatably connected to the base plate. The drive screw also passes through and is threadedly connected to the two sliders, with the threaded directions of the drive screw and the two sliders being opposite. The sliders are open and slidably connected to the base plate. The two push rods are respectively hinged to the two sliders one-to-one, and the end of the push rod away from the slider is hinged to the fixing seat. This application has the effect of reducing the height difference between two adjacent pipe openings. A sand and gravel foundation is laid under the pipe base, with the foundation pad being the same width as the bottom of the trench. The pipe joint uses a flexible rubber ring joint. The working surface outside the pipe is cleaned, and the rubber ring fitted on the spigot should be straight and free from twisting.

[0004] When connecting two pipes, flexible socket connection or flange connection is usually used. Flexible socket connection refers to installing a rubber ring between the socket and spigot of the two pipes. The elastic deformation of the rubber ring is used to achieve a seal. During installation, the rubber ring is put on the spigot and then the spigot is inserted into the socket, so that the rubber ring is compressed in the socket to form a seal. Flange connection refers to installing flanges at both ends of the concrete pipe. Usually, a concrete structure with flange connection holes is poured at the end of the pipe and the two flanges are fixed with bolts.

[0005] Flexible connections require rotating the pipe to ensure the sealing ring is evenly pressurized across the entire circumference of the concrete pipe, achieving a tight and uniform seal. Similarly, flange connections require rotating the pipe to align the holes on the flanges before installation. However, existing concrete pipes are placed directly on the laid gravel, and the pipes themselves are heavy, making rotation time-consuming and laborious, which is detrimental to pipe connections and affects work efficiency. Utility Model Content

[0006] The purpose of this application is to provide a concrete pre-embedded pipe positioning device to solve the problem that the concrete pipes are placed directly on the laid sand and gravel, and the pipes are heavy, which makes it time-consuming and laborious to rotate the pipes, which is not conducive to the connection between pipes and affects work efficiency.

[0007] The technical solution adopted in this application is as follows: A concrete pre-embedded pipe positioning device includes a positioning plate, a support block fixedly connected to the upper surface of the positioning plate, a moving groove opened on the upper surface of the support block, a moving block slidably connected to the inner wall of the moving groove, a bolt fixedly passing through the side of the moving block, a bidirectional threaded rod threadedly connected to the inner wall of the bolt, a support plate fixedly connected to the upper surface of the support block, a round rod rotatably connected to the inner wall of the support plate, a second cylinder fixedly sleeved on the surface of the round rod, a limit plate fixedly connected to the upper surface of the support block, a first cylinder rotatably connected to the back of the limit plate, and a concrete pipe provided on the upper surface of the second cylinder and the first cylinder.

[0008] Preferably, a gasket is fixedly fitted on the surface of the second cylinder. The gasket is made of rubber. By setting the gasket to be made of rubber, which is elastic, when the gasket is attached to the concrete pipe, the rubber is squeezed to increase the friction between the concrete pipe and the second cylinder. When the concrete pipe is pushed, it is convenient to use the second cylinder to make the concrete pipe rotate.

[0009] Preferably, there are two positioning plates, and eight cone rods are inserted through the lower surface of the positioning plates. The cone rods are arranged in groups of four, and the two groups of cone rods are arranged in a rectangular array at the four corners of the lower surface of the two positioning plates. Each group of four cone rods is inserted through a positioning plate. Then, the cone rods are chiseled into the soil using external tools to fix the positioning plates.

[0010] Preferably, a connecting plate is fixedly connected to the back of the support block, a vertical plate is fixedly connected to the upper surface of the connecting plate, and a rotating rod is rotatably connected to the back of the vertical plate. There are two rotating rods, and the two rotating rods are located on both sides of the upper surface of the connecting plate. A second clamp is fixedly fitted on the surface of the left rotating rod on the upper surface of the connecting plate, and a first clamp is fixedly fitted on the surface of the right rotating rod on the upper surface of the connecting plate. When the concrete pipe rotates, it pushes the second clamp and the first clamp to rotate respectively. The second clamp and the first clamp rotate and respectively fasten to both sides of the concrete pipe, limiting the position of the concrete pipe.

[0011] Preferably, bolts are threaded through the sides of the second clamp and the first clamp, and nuts are threaded onto the surface of the bolts. After the second clamp and the first clamp are fastened to the surface of the concrete pipe, the bolts are passed through the second clamp and the first clamp respectively, and then the nuts are rotated to fix the second clamp and the first clamp together.

[0012] Preferably, a drive handle is fixedly connected to the end of the bidirectional threaded rod away from the support block. The drive handle is circular in shape. By setting the shape of the drive handle to be circular, it is easy for the user to hold both sides of the drive handle to drive the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod thereby uses the bolt to push the moving block to move.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, the rotation of the bidirectional threaded rod utilizes the internal threaded cylinder to drive the moving block to move. The movement of the moving block then drives the second cylinder to move until the distance between the second cylinders is the same as the diameter of the concrete pipe. At this point, the concrete pipe is placed above the first cylinder. Then, the bidirectional threaded rod is rotated in the opposite direction. The rotation of the bidirectional threaded rod utilizes the internal threaded cylinder to drive the support plate to move again. The movement of the support plate drives the second cylinder to move until the sleeve is tightly attached to both sides of the concrete pipe. The rotation is then stopped, and an external rubber ring is fitted onto the surface of the concrete pipe. Then, other external pipes are fastened to the rubber ring on the surface of the concrete pipe. After that, the concrete pipe, the second cylinder, and the first cylinder are pushed to rotate. At this time, the concrete pipe rotates, thus enabling the device to facilitate the rotation of the concrete pipe. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example:

[0021] Reference Figure 2-3 A concrete pre-embedded pipe positioning device includes a positioning plate 1, a support block 2 fixedly connected to the upper surface of the positioning plate 1, a movable groove 5 formed on the upper surface of the support block 2, a movable block 6 slidably connected to the inner wall of the movable groove 5, an internally threaded cylinder 22 fixedly inserted through the side of the movable block 6, a bidirectional threaded rod 16 threadedly connected to the inner wall of the internally threaded cylinder 22, a support plate 7 fixedly connected to the upper surface of the support block 2, a round rod 19 rotatably connected to the inner wall of the support plate 7, a second round cylinder 8 fixedly sleeved on the surface of the round rod 19, a limiting plate 3 fixedly connected to the upper surface of the support block 2, a first round cylinder 4 rotatably connected to the back of the limiting plate 3, and a concrete pipe 10 disposed on the upper surfaces of the second round cylinder 8 and the first round cylinder 4. The bidirectional threaded rod 16 is rotated using the internally threaded cylinder 2. 2. Push the moving block 6 to move. The movement of the moving block 6 then drives the second cylinder 8 to move until the distance between the second cylinders 8 is the same as the diameter of the concrete pipe 10. Place the concrete pipe 10 above the first cylinder 4. Then, drive the bidirectional threaded rod 16 to rotate in the opposite direction. The rotation of the bidirectional threaded rod 16 drives the support plate 7 to move again through the internal threaded cylinder 22. The movement of the support plate 7 drives the second cylinder 8 to move until the sleeve 9 is tightly attached to both sides of the concrete pipe 10. Stop rotating and drive the handle 17 to put the external rubber ring on the surface of the concrete pipe 10. Then, fasten the other external pipes onto the rubber ring on the surface of the concrete pipe 10. Then push the concrete pipe 10, the second cylinder 8 and the first cylinder 4 to rotate. At this time, the concrete pipe 10 rotates.

[0022] Reference Figure 1-2 A gasket 9 is fixedly fitted on the surface of the second cylinder 8. The gasket 9 is made of rubber. By setting the material of the gasket 9 to rubber, the rubber is elastic. When the gasket 9 is attached to the concrete pipe 10, the rubber is squeezed to increase the friction between the concrete pipe 10 and the second cylinder 8. When the concrete pipe 10 is pushed, it is convenient to use the second cylinder 8 to make the concrete pipe 10 rotate.

[0023] Reference Figure 1-2 There are two positioning plates 1. The lower surface of the positioning plate 1 is provided with a cone rod 18. There are eight cone rods 18 in total. Every four cone rods 18 form a group. The two groups of cone rods 18 are arranged in a rectangular array at the four corners of the lower surface of the two positioning plates 1. Every four cone rods 18 are individually inserted into one positioning plate 1. Then, the cone rods 18 are chiseled into the soil using external tools to fix the positioning plate 1 at the pre-embedded location.

[0024] Reference Figure 2-3A connecting plate 20 is fixedly connected to the back of the support block 2. A vertical plate 21 is fixedly connected to the upper surface of the connecting plate 20. A rotating rod 15 is rotatably connected to the back of the vertical plate 21. There are two rotating rods 15, and the two rotating rods 15 are located on both sides of the upper surface of the connecting plate 20. A second clamp 12 is fixedly fitted on the surface of the left rotating rod 15 on the upper surface of the connecting plate 20, and a first clamp 11 is fixedly fitted on the surface of the right rotating rod 15 on the upper surface of the connecting plate 20. When the concrete pipe 10 rotates, it pushes the second clamp 12. The second clamp 12 and the first clamp 11 rotate, and the second clamp 12 and the first clamp 11 rotate to fasten to both sides of the concrete pipe 10, limiting the concrete pipe 10. Bolts 14 are inserted through the sides of the second clamp 12 and the first clamp 11, and nuts 13 are threaded onto the surface of the bolts 14. After the second clamp 12 and the first clamp 11 are fastened to the surface of the concrete pipe 10, the bolts 14 are passed through the second clamp 12 and the first clamp 11 respectively, and then the nuts 13 are rotated to fix the second clamp 12 and the first clamp 11 together.

[0025] Reference Figure 1-3 The end of the bidirectional threaded rod 16 away from the support block 2 is fixedly connected to a drive handle 17. The drive handle 17 is circular in shape. By setting the drive handle 17 to be circular, it is easy for the user to hold both sides of the drive handle 17 to drive the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 thereby uses the bolt 14 to push the moving block 6 to move.

[0026] The implementation principle of the concrete pre-embedded pipe positioning device embodiment of this application is as follows: First, rotating the handle 17 drives the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 uses the internal threaded cylinder 22 to push the moving block 6 to move. The movement of the moving block 6 then drives the second cylinder 8 to move until the distance between the second cylinders 8 is the same as the diameter of the concrete pipe 10. Then, the concrete pipe 10 is placed above the first cylinder 4. Next, rotating the bidirectional threaded rod 16 in the opposite direction drives the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 uses the internal threaded cylinder 22 to drive the support plate 7 to move again. The movement of the support plate 7 drives the second cylinder 8 to move until the sleeve 9 is tightly attached to both sides of the concrete pipe 10. Then, rotating the handle 17 stops. 7. An external rubber ring is fitted onto the surface of the concrete pipe 10. Then, other external pipes are fastened to the surface of the concrete pipe 10. The concrete pipe 10, the second cylinder 8, and the first cylinder 4 are then pushed to rotate. The concrete pipe 10 rotates. After the concrete pipe 10 rotates, the second clamp 12 and the first clamp 11 are pushed to rotate. The second clamp 12 and the first clamp 11 are fastened to both sides of the concrete pipe 10. The bolts 14 are passed through the second clamp 12 and the first clamp 11 respectively. Then, the nut 13 is rotated to fix the second clamp 12 and the first clamp 11, limiting the concrete pipe 10. This makes the device easy to rotate the concrete pipe.
