Description

Technical Field

[0001] This utility model relates to the field of support and positioning technology, specifically to an adjustable support and positioning device. Background Technology

[0002] In the field of pipeline engineering, pipeline lining technology is constantly evolving. Stainless steel, as a high-quality material, is often used for pipeline lining to enhance the pipeline's corrosion resistance, wear resistance, and other properties, thereby improving pipeline performance and service life. When using stainless steel lining technology for repair, a support and positioning device can provide support for the stainless steel lining tube inside the original pipeline, ensuring a tight fit between the lining tube and the original pipeline, restoring the pipeline's sealing and water delivery capacity.

[0003] The installation of stainless steel linings requires addressing a series of technical challenges to ensure their quality and stability. Support plates play a crucial role in the installation of stainless steel pipe linings. Existing support plates have some shortcomings in use; their complex structure, consisting of multiple components, not only increases manufacturing difficulty and cost but also makes installation and disassembly cumbersome, time-consuming, and labor-intensive.

[0004] Patent document CN217482317U discloses a pipe repair liner support device. The device is easily movable within the pipe and suitable for adjusting the support position of the liner. After the first support member provides support, the liner is initially spot-welded. After adjusting the position of the vehicle body to perform multi-point welding between the liner and the pipe, a second support member is used for further welding of the liner to the pipe to be repaired. During welding, rotating the second support member prevents the equipment from interfering with the welding work. In this technical solution, the device is pushed into the pipe by pushing the vehicle body. The two first struts of the first support member simultaneously open, allowing the liner to adhere to the inner wall of the pipe. The liner is welded to the inner wall of the pipe at the support point of the first support member. After adjusting the position of the vehicle body and supporting it with the first support member, welding is repeated until the position of the liner is fixed. Then, the position of the vehicle body is adjusted, and the multiple second struts of the second support member open for further welding of the liner to the inner wall of the pipe. The position of the second support plate affects the welding process, and the second support member can be rotated. The stainless steel liner is pre-supported by the first support member, then pre-fixed inside the pipe, and then welded after being supported at multiple points by the second support member. Since the axle cannot be effectively positioned inside the pipe, it is inconvenient to position the stainless steel liner when pre-supporting it with the first support member. When supporting the stainless steel liner with the second support member, although the second support member can provide multi-point support in the circumferential direction, when the stainless steel liner is long, it is necessary to frequently move the second support member to support it. Moving the second support member requires retracting multiple second support rods, which is quite troublesome. Utility Model Content

[0005] The main purpose of this utility model is to provide an adjustable support and positioning device for effectively supporting and positioning the stainless steel lining inside a pipe.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An adjustable support and positioning device includes a central tube with positioning components on both sides, which can fix the central tube inside the pipe. A support component is fitted on the central tube between the two positioning components. The support component includes a second sleeve fitted on the central tube, with multiple rotating sleeves rotatably fitted on the outer side of the second sleeve, and multiple fixed sleeves fixed on the outer edge of the rotating sleeves. It also includes multiple support units, one end of which is inserted into the fixed sleeve to support the stainless steel lining inside the pipe.

[0008] Specifically, the positioning component includes a first sleeve, which is sleeved on the outside of the central tube. Two first branch pipes are fixed on the first sleeve and are symmetrically arranged. A first screw jack is fixed to the end of the first branch pipe away from the first sleeve, and a first arc plate is fixed to the telescopic end of the first screw jack.

[0009] Specifically, the length direction of the first branch pipe is parallel to the radial direction of the central pipe, and the movement direction of the telescopic end of the first screw jack is parallel to the radial direction of the central pipe.

[0010] Specifically, the first sleeve is threaded with a first locking bolt, one end of which is tightly pressed against the outer wall of the central tube.

[0011] Specifically, the second sleeve is threaded with a second locking bolt, one end of which is tightly pressed against the outer wall of the central tube.

[0012] Specifically, the plurality of rotating sleeves are evenly distributed in the axial direction of the second sleeve, and anti-rotation bolts are threadedly connected to the rotating sleeves, with one end of the anti-rotation bolts tightly abutting against the outer wall of the second sleeve.

[0013] Specifically, the plurality of fixed sleeves are evenly distributed around the circumference of the rotating sleeve, the axial direction of the fixed sleeve is parallel to the radial direction of the central tube, and the fixed sleeve is threaded with limit bolts.

[0014] Specifically, the support unit includes a second branch pipe, one end of which is fixed with a second screw jack, and the telescopic end of the second screw jack is fixed with a second arc-shaped plate.

[0015] Specifically, an arc-shaped groove is formed on the outer edge surface of the second arc-shaped plate. The axial direction of the arc-shaped groove is parallel to the axial direction of the second arc-shaped plate. A round rod is inserted into the arc-shaped groove, and the part of the round rod protrudes to the outside of the second arc-shaped plate.

[0016] Specifically, the central angle of the arc-shaped groove is 190 degrees.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The symmetrically arranged positioning components drive the first arc plate to move radially through the first screw jack, so that the central tube coincides with the pipeline axis. After the central tube is fixed by the double positioning components, it forms a stable force-bearing core, providing a rigid matrix that resists torsion and bending for subsequent inner lining support.

[0019] 2. The rotating sleeve can rotate circumferentially around the central tube, and the evenly distributed fixed sleeves on its circumference allow for 360° position adjustment of the support unit, covering any weak point in the pipe lining. The second screw jack drives the second arc-shaped plate to extend and retract radially, precisely controlling the magnitude of the support force and the contact depth to avoid overpressure damage to the lining. The support unit adopts a plug-in design for quick assembly and disassembly, adapting to the number of support points required under different working conditions.

[0020] 3. The round rod is embedded in the arc groove of the second arc plate, forming a line contact with the inner lining, concentrating pressure to correct local depressions or protrusions. The 190° central angle arc groove ensures that the round rod is mechanically locked, remaining stable and not falling off under high pressure support.

[0021] 4. This device employs a step-by-step positioning strategy during use. First, the two ends of one side of the stainless steel liner are fixed by the collinear support unit, and then the remaining support points are added to prevent the liner from shifting. In single-support unit mode, the rotating sleeve can fine-tune the support position and respond in real time to changes in the liner's fit. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to 1- Figure 4 As shown, an adjustable support and positioning device includes a central tube 1, with positioning components fitted on both sides of the central tube 1. The positioning components can fix the central tube 1 inside the pipe 16.

[0029] The positioning assembly includes a first sleeve 2, which is sleeved on the outside of the central tube 1. A first locking bolt 6 is threaded onto the first sleeve 2, and one end of the first locking bolt 6 is tightly pressed against the outer wall of the central tube 1.

[0030] Two first branch pipes 3 are fixed on the first sleeve 2. The two first branch pipes 3 are symmetrically arranged. A first screw jack 4 is fixed at the end of the first branch pipe 3 away from the first sleeve 2. A first arc plate 5 is fixed on the telescopic end of the first screw jack 4.

[0031] The length direction of the first branch pipe 3 is parallel to the radial direction of the central pipe 1, and the movement direction of the telescopic end of the first screw jack 4 is parallel to the radial direction of the central pipe 1.

[0032] A support component is fitted onto the central tube 1 between the two positioning components.

[0033] The support assembly includes a second sleeve 7 fitted onto the central tube 1, with a second locking bolt 8 threaded onto the second sleeve 7, one end of which abuts against the outer wall of the central tube 1. Multiple rotating sleeves 9 are rotatably fitted onto the outer side of the second sleeve 7, evenly distributed along the axial direction of the second sleeve 7. Anti-rotation bolts 10 are threaded onto each rotating sleeve 9, one end of which abuts against the outer wall of the second sleeve 7.

[0034] Multiple fixed sleeves 11 are fixed on the outer edge of the rotating sleeve 9. The multiple fixed sleeves 11 are evenly distributed around the circumference of the rotating sleeve 9. The axial direction of the fixed sleeves 11 is parallel to the radial direction of the central tube 1. Limit bolts 12 are threadedly connected to the fixed sleeves 11.

[0035] It also includes multiple support units, one end of which is inserted into the fixed sleeve 11 to support the stainless steel lining 17 inside the pipe 16.

[0036] The support unit includes a second branch pipe 13, one end of which is fixed to a second screw jack 14, and the telescopic end of the second screw jack 14 is fixed to a second arc-shaped plate 15.

[0037] When it is necessary to support the stainless steel liner 17 inside the pipe 16, the central tube 1 is made to penetrate the stainless steel liner 17 inside the pipe 16, and the stainless steel liner 17 is positioned between the two positioning components. Then, the first screw jack 4 is activated, so that the first arc plate 5 is pressed tightly against the inner wall of the pipe 16 and the central tube 1 is concentric with the pipe 16. At this time, the central tube 1 is stably positioned inside the pipe 16, providing a force point when the support components are used to support the stainless steel liner 17 inside the pipe 16.

[0038] To further improve the stability of the central tube 1 within the pipe 16, the two positioning components are perpendicular to each other.

[0039] A support unit is installed in a fixed sleeve 11 on the rotating sleeve 9 at the end of the second sleeve 7. The rotating sleeve 9 at the end of the second sleeve 7 can be rotated so that the two support units at the end of the second sleeve 7 are collinear. Then, the anti-rotation bolt 10 is rotated to stop the rotating sleeve 9 at the end of the second sleeve 7 from rotating. The two collinear support units can support and position both ends of the stainless steel lining 17 on one side of the pipe 16.

[0040] When the support unit is connected to the fixed sleeve 11, the second branch pipe 13 is inserted into the fixed sleeve 11, and then the limiting bolt 12 is rotated to fix the second branch pipe 13 into the fixed sleeve 11.

[0041] When the support unit supports or positions the stainless steel liner 17, the second screw jack 14 is activated, and the second arc plate 15 moves toward the inner wall of the pipe 16, which can squeeze, position or support the stainless steel liner 17 inside the pipe 16.

[0042] Then other support units can be installed into other fixed sleeves 11, and the stainless steel lining 17 inside the pipe 16 can be supported at multiple points using other support units.

[0043] Since the rotating sleeve 9 can rotate, when only one of the multiple fixed sleeves 11 on the outside of the rotating sleeve 9 is equipped with a support unit, the position of the support unit can be adjusted when the rotating sleeve 9 is rotated, so that the second arc plate 15 of the support unit can support the designated position of the stainless steel lining 17 inside the pipe 16, making it more convenient to use.

[0044] This device features a rotatable rotating sleeve 9 with multiple fixed sleeves 11 on its outer side. When supporting the stainless steel lining 17 inside the pipe 16, it can first support and position one end of the stainless steel lining 17, and then use other support units to provide multi-point support for the stainless steel lining 17. The position of the support units on the rotating sleeve 9 can change as it rotates, facilitating support at designated locations on the stainless steel lining 17 and ensuring a tight fit between the stainless steel lining 17 and the inner wall of the pipe 16.

[0045] Example 2: Based on Example 1, referring to... Figure 1 and Figure 4 As shown, an arc-shaped groove 18 is formed on the outer edge surface of the second arc-shaped plate 15. The axial direction of the arc-shaped groove 18 is parallel to the axial direction of the second arc-shaped plate 15. A round rod 19 is inserted into the arc-shaped groove 18, and part of the round rod 19 protrudes to the outside of the second arc-shaped plate 15. The central angle of the arc-shaped groove 18 is 190 degrees.

[0046] Because the central angle of the arc groove 18 is 190 degrees, the round rod 19 can be prevented from falling out of the arc groove 18 after being inserted into it. After the round rod 19 is inserted into the arc groove 18, part of the round rod 19 protrudes to the outside of the second arc plate 15. The second arc plate 15 can make line contact with the stainless steel lining 17 inside the pipe 16 through the round rod 19, which can perform localized and focused compression repair on the deformed part of the stainless steel lining 17.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
