Description

Technical Field

[0001] The invention belongs to the technical field of engineering construction, and in particular relates to a supporting device for a tubular structure and a use method thereof. Background Art

[0002] Modern buildings often involve large-section hollow structures, such as various silo structures, chimneys, and various large-diameter pipes, among which large-diameter pipes are the most typical. Such structures are mostly made of rolled steel plates as the main material, with various structural cross-sections and lengths, so they cannot be produced in standardized factories. They often need to be pre-rolled and formed in the structure factory, transported to the site in sections, and then assembled in the air or on the ground, and then hoisted in sections to the specified height for installation. Pipes have large diameters, thin walls, and are easy to deform during production and hoisting.

[0003] To prevent pipeline deformation, the traditional approach is to take temporary reinforcement measures after the pipeline is completed, that is, to set up temporary steel structure cross braces inside the pipeline, and then the cross braces are manually cut off by workers at high altitude after the pipeline is installed in place. This method requires a lot of measures and materials, increases the duration of high-altitude operations, affects the total construction period, and increases the safety risk of operations. At the same time, in order to reduce cumulative errors and ensure the verticality (concentricity) of the structure, workers are required to repeatedly measure the center of the cross section during the installation process, which is cumbersome. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a support device for a tubular structure and a method of use, which is particularly suitable for simultaneous measurement operations during support construction of a pipeline.

[0010] Furthermore, the sleeve portion includes a sleeve body and a rotating shaft positioning member, wherein the rotating shaft positioning member is disposed on the sleeve body, and the rotating shaft positioning member is connected to the branch adjusting member.

[0011] Furthermore, the main bearing rod is provided with a thread that cooperates with the sleeve adjustment piece, and is also provided with a positioning plate, and the positioning plate is elastically connected to the folding piece to enable the folding piece to return to an initial state when not affected by external force.

[0012] Furthermore, it also includes a base unit, and the base unit is arranged below the main bearing rod;

[0013] The base unit comprises a bracket, a supporting leg and a telescopic leg. The bracket is arranged at one end of the supporting leg, and the telescopic leg is arranged at the other end.

[0014] In a second aspect, a method for using a support device for a tubular structure is provided, comprising:

[0015] adjusting the telescopic legs within the conduit to adjust the height of the base unit;

[0016] opening the branch support portion;

[0017] Adjust the locking member to adjust the length of the inner support member extending from the outer support member until the inner support member is tightly pressed against the inner wall of the pipe;

[0018] Measure the inner diameter of the pipe and determine the center of gravity.

[0019] Furthermore, installing the branch support portion comprises the following steps:

[0020] Adjust the sleeve adjusting member to move on the main bearing rod to push the sleeve portion;

[0021] The movement of the sleeve portion drives the outer support member connected through the branch adjusting member, so that the angle between the outer support member and the inner wall of the pipeline is gradually increased to achieve the optimal vertical angle for supporting force.

[0022] Further, measuring the inner diameter of the pipeline and determining the center of gravity line includes the following steps:

The load-bearing rod is always in a horizontal state, providing a stable foundation for the entire supporting device; the spirit level ensures the horizontality of the main load-bearing rod, providing a stable and reliable benchmark for the measurement of the distance meter and the plumb line. The distance meter accurately measures the inner diameter of the pipeline to ensure that the pipeline size meets the design requirements and avoids problems such as loose pipeline connection or leakage caused by pipe diameter errors; the positioning shaft provides a stable installation position for the distance meter, ensuring that the distance meter can always remain at the accurate measurement point when measuring the inner diameter of the pipeline, improving the accuracy and repeatability of the measurement data. At the same time, the plumb line suspended on the positioning shaft uses the principle of gravity to determine the center of gravity of the pipeline. Since the relative position of the positioning shaft and the main load-bearing rod is fixed, the center of gravity determined by the plumb line and the inner diameter data measured by the distance meter are in the same coordinate system. The measurement results of the two are interrelated and accurate and reliable, providing precise positioning and size reference for pipeline installation, which helps to improve the accuracy and quality of pipeline installation.

[0038] The present disclosure is described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are described. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] like Figure 1 As shown, the present invention provides a supporting device for a tubular structure, comprising a main bearing rod 101, a sleeve portion 200, a sleeve adjusting piece 102, a branch supporting portion 300, a folding piece 103 and a branch adjusting piece 104, the sleeve portion 200 and the sleeve adjusting piece 102 are arranged on the main bearing rod 101, the sleeve adjusting piece 102 is used for driving the sleeve portion 200 to move by moving on the main bearing rod 101, the folding piece 103 is arranged on the main bearing rod 101, so that the folding piece 103 can flip around the main bearing rod 101 in a plane, the branch supporting portion 300 is arranged on the folding piece 103, one end of the branch adjusting piece 104 is arranged on the sleeve portion 200, and the other end is arranged on the branch supporting portion 300.

[0040] By adopting the above device, the opening and closing of the branch support part is controlled by adjusting the sleeve adjustment part, which plays the role of supporting the pipeline and dismantling it after the construction is completed, avoiding the problem of using temporary steel structure cross braces and workers manually cutting them off at high altitude after the pipeline is installed in place, thereby saving measures and materials and reducing the duration of high-altitude operations.

[0041] In order to solve the problem of needing to measure the pipeline during the pipeline support process, an implementation method is provided in this embodiment.

[0042] In one embodiment, a measuring unit is further included, and the measuring unit is arranged on the main bearing rod 101; the measuring unit includes a rangefinder 401, a positioning shaft 402 and a plumb line 403, one end of the positioning shaft 402 is arranged at the end of the main bearing rod 101, and the other end is provided with the plumb line 403, and the rangefinder 401 is sleeved on the positioning shaft 402.

[0043] By adopting the above device, the support, measurement and adjustment functions are integrated into one device, which reduces the number of equipment and tools required on the construction site and avoids the time wasted by frequent switching and calibration between different equipment. The positioning shaft provides a stable installation position for the distance meter, ensuring that the distance meter can always remain at the accurate measurement point when measuring the inner diameter of the pipeline, improving the accuracy and repeatability of the measurement data. At the same time, the plumb line hanging on the positioning shaft uses the principle of gravity to determine the center of gravity of the pipeline. Since the relative position of the positioning shaft and the main bearing rod is fixed, the center of gravity determined by the plumb line and the inner diameter data measured by the distance meter are in the same coordinate system. The measurement results of the two are interrelated and accurate and reliable, providing precise positioning and size reference for pipeline installation, which helps to improve the accuracy and quality of pipeline installation.

[0044] In order to solve the problem of insufficient measurement accuracy when measuring pipelines, an implementation method is provided in this embodiment.

[0045] In one embodiment, the measuring unit further includes a level 404 , and the level 404 is disposed on the main bearing bar 101 .

[0046] By adopting the above device, the level meter is set to ensure the horizontality of the main bearing rod, which provides a stable and reliable benchmark for the measurement of the distance meter and the plumb line. The distance meter accurately measures the inner diameter of the pipeline to ensure that the pipeline size meets the design requirements and avoids problems such as loose pipeline connection or leakage due to pipe diameter error.

[0047] In order to solve the problem that different pipe diameters in pipeline support require different support device lengths, an implementation method is provided in this embodiment.

[0048] In one embodiment, the branch support portion 300 includes an inner support member 301, an outer support member 302 and a locking member 303, one end of the outer support member 302 is arranged on the folding member 103, and the other end is provided with the inner support member 301, the outer support member 302 is connected to the branch adjusting member 104, and the locking member 303 is arranged at the connection between the outer support member 302 and the inner support member 301, and is used to position the inner support member 301.

[0049] By adopting the above device, the position of the sleeve part can be flexibly adjusted through the sleeve adjustment part, thereby changing the angle and supporting strength between the branch support part and the inner wall of the pipe, which can effectively meet the installation requirements of pipes with different diameters and wall thicknesses. There is no need to customize special supporting devices for each specification of pipes, which improves the versatility and applicability of the device.

[0050] In order to solve the problem of insufficient angle adjustment and durability of the branch adjusting member during operation, an implementation method is provided in this embodiment.

[0051] In one embodiment, the sleeve portion 200 includes a sleeve body 201 and a shaft positioning member 202 . The shaft positioning member 202 is disposed on the sleeve body 201 , and the shaft positioning member 202 is connected to the branch adjusting member 104 .

[0052] The above device provides a stable and precise installation position for the branch adjustment member by setting the shaft positioning block, ensuring that the branch adjustment member can only rotate in a predetermined direction and angle during operation. As a key component connecting the sleeve part and the branch adjustment member, the shaft positioning block bears various forces transmitted, including friction during rotation, component gravity, and the reaction force of the pipeline on the supporting structure. Through reasonable design and material selection, the shaft positioning block can effectively disperse and withstand these forces, enhance the connection strength between the sleeve part and the branch adjustment member, and prevent the connection from loosening or being damaged under high-load working conditions.

[0053] In order to solve the problem of angle adjustment and durability of the folding member during operation, an implementation method is provided in this embodiment.

[0054] In one embodiment, the main bearing rod 101 is provided with a thread that cooperates with the sleeve adjustment member 102, and is also provided with a positioning plate 105. The positioning plate 105 is elastically connected to the folding member 103 to restore the folding member 103 to its initial state when not affected by external force.

[0055] By adopting the above-mentioned device, a stable and precise installation position is provided for the folding part by setting a positioning plate, ensuring that the folding part can only rotate in a predetermined direction and angle during operation. As a key component connecting the folding part and the main bearing rod, the positioning plate bears various forces transmitted, including friction during rotation, component gravity, and the reaction force of the pipeline on the supporting structure. Through reasonable design and material selection, the positioning plate can effectively disperse and withstand these forces, enhance the connection strength between the folding part and the main bearing rod, and prevent the connection from loosening or being damaged under high-load working conditions. Setting a thread is a way to enable the sleeve adjustment part to move on the main bearing rod. Any other settings that enable the sleeve adjustment part to move on the main bearing rod are within this protection range, such as setting a slide groove and positioning device on the main bearing rod that cooperates with the sleeve adjustment part.

[0056] In order to solve the problem of requiring manual support of the device and determination of the height of the device during the initial setting of the device, an implementation method is provided in this embodiment.

[0058] By adopting the above device, under different terrain conditions, such as uneven ground, slopes or construction sites with certain height differences, the height of the telescopic legs can be adjusted to ensure that the main bearing rod is always in a horizontal state, providing a stable foundation for the entire support device.
