Description

Technical Field

[0001] This utility model belongs to the field of engineering construction technology, and in particular relates to a support device for tubular structures. Background Technology

[0002] Modern architecture frequently involves large-section hollow structures, such as various silos, chimneys, and large-diameter pipes, with large-diameter pipes being the most typical. These structures are primarily made of rolled steel plates, and their cross-sections vary greatly in length, making standardized factory production impossible. They often require pre-rolling at a structural plant, transporting them to the site in sections, and then assembling them in the air or on the ground before hoisting them to the designated height for installation. Pipes present construction challenges due to their large diameter, thin walls, and susceptibility to deformation during fabrication and hoisting.

[0003] To prevent pipe deformation, the traditional approach is to implement temporary reinforcement measures after pipe fabrication. This involves installing temporary steel cross braces inside the pipe, which are then manually removed by workers at height after the pipe is installed in place. This method consumes a large amount of materials, increases the time spent working at height, affects the overall project schedule, and increases operational safety risks. Furthermore, to reduce cumulative errors and ensure structural verticality (concentricity), workers need to repeatedly measure the center of the cross-section during installation, making the process cumbersome. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a support device for tubular structures, which is particularly suitable for simultaneous measurement operations when supporting pipelines during construction.

[0005] The technical solution adopted by this utility model is as follows: Firstly, a support device for a tubular structure is provided, including a main bearing rod, a sleeve portion, a sleeve adjusting member, a branch support portion, a folding member, and a branch adjusting member. The sleeve portion and the sleeve adjusting member are disposed on the main bearing rod. The sleeve adjusting member is used to move the sleeve portion by moving on the main bearing rod. The folding member is disposed on the main bearing rod, so that the folding member can rotate around the main bearing rod in a plane. The branch support portion is disposed on the folding member. One end of the branch adjusting member is disposed on the sleeve portion, and the other end is disposed on the branch support portion.

[0006] Furthermore, it also includes a measuring unit, which is mounted on the main support rod;

[0007] The measuring unit includes a rangefinder, a positioning shaft, and a plumb bob. One end of the positioning shaft is located at the end of the main support rod, and the plumb bob is located at the other end. The rangefinder is sleeved on the positioning shaft.

[0008] Furthermore, the measuring unit also includes a level, which is mounted on the main support rod.

[0009] Furthermore, the branch support includes an inner support, an outer support, and a locking member. One end of the outer support is disposed on the folding member, and the other end is disposed on the inner support. The outer support is connected to the branch adjustment member. The locking member is disposed at the connection between the outer support and the inner support and is used to position the inner support.

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

[0011] Furthermore, the main bearing rod is provided with a thread that mates with the sleeve adjustment component, and a positioning plate is also provided. The positioning plate is elastically connected to the folding component to allow the folding component to return to its initial state when not subjected to external force.

[0012] Furthermore, it also includes a base unit, which is disposed below the main support rod;

[0013] The base unit includes a support, a support leg, and a telescopic leg. One end of the support leg is provided with the support, and the other end is provided with the telescopic leg.

[0014] The advantages and positive effects of this utility model are as follows: By adopting the above-mentioned technical solution, the support, measurement, and adjustment functions are integrated into one device, reducing the number of equipment and tools required on the construction site and avoiding the time wasted on frequent switching and calibration between different devices; the position of the sleeve part can be flexibly adjusted through the sleeve adjustment component, thereby changing the angle and support force between the branch support part and the inner wall of the pipe, which can effectively meet the installation needs of pipes with different diameters and wall thicknesses, eliminating the need to customize special support devices for each specification of pipe, thus improving the versatility and applicability of the device; the elastic connection between the positioning plate and the folding part ensures that the folding part can accurately return to its initial state when not subjected to external force, ensuring that the position and performance of the branch support part are consistent every time it is used, thus improving the stability and reliability of the device; under different terrain conditions, such as construction sites with uneven ground, slopes, or certain height differences, the height of the telescopic legs can be adjusted to ensure The main support rod remains horizontal, providing a stable foundation for the entire support system. A level ensures the main support rod's horizontality, providing a stable and reliable benchmark for the distance measuring instrument and plumb bob measurements. The distance measuring instrument accurately measures the pipe's inner diameter, ensuring the pipe dimensions meet design requirements and preventing issues such as loose pipe connections or leaks due to diameter errors. The positioning shaft provides a stable installation position for the distance measuring instrument, ensuring it remains at the accurate measurement point when measuring the pipe's inner diameter, improving the accuracy and repeatability of the measurement data. Simultaneously, the plumb bob suspended on the positioning shaft uses gravity to determine the pipe's center of gravity. Because the relative position of the positioning shaft and the main support rod is fixed, the center of gravity determined by the plumb bob and the inner diameter data measured by the distance measuring instrument are in the same coordinate system. The measurement results are correlated and accurate, providing precise positioning and dimensional references for pipe installation, thus improving the precision and quality of pipe installation.

[0025] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.

[0026] like Figure 1 As shown, this utility model provides a support device for a tubular structure, including a main support rod 101, a sleeve portion 200, a sleeve adjusting member 102, a branch support portion 300, a folding member 103, and a branch adjusting member 104. The sleeve portion 200 and the sleeve adjusting member 102 are disposed on the main support rod 101. The sleeve adjusting member 102 is used to move the sleeve portion 200 by moving on the main support rod 101. The folding member 103 is disposed on the main support rod 101, so that the folding member 103 can rotate around the main support rod 101 in a plane. The branch support portion 300 is disposed on the folding member 103. One end of the branch adjusting member 104 is disposed on the sleeve portion 200, and the other end is disposed on the branch support portion 300.

[0027] Using the above-mentioned device, the opening and closing of the branch support can be controlled by adjusting the sleeve adjustment component, which serves to support the pipeline and dismantle it after construction. This avoids the problem of using temporary steel cross braces and having workers manually cut them at height after the pipeline is installed, thus saving materials and reducing the time spent on high-altitude operations.

[0028] To address the issue of measuring the pipeline during pipeline support, this embodiment provides an implementation method.

[0029] In one embodiment, a measuring unit is also included, which is disposed on the main support rod 101. The measuring unit includes a rangefinder 401, a positioning shaft 402 and a plumb bob 403. One end of the positioning shaft 402 is disposed at the end of the main support rod 101, and the plumb bob 403 is disposed at the other end. The rangefinder 401 is sleeved on the positioning shaft 402.

[0030] By integrating support, measurement, and adjustment functions into a single device, the number of equipment and tools required on-site is reduced, and the time wasted on frequent switching and calibration between different devices is avoided. The positioning axis provides a stable installation position for the rangefinder, ensuring it remains at the accurate measurement point when measuring the pipe's inner diameter, thus improving the accuracy and repeatability of the measurement data. Simultaneously, the plumb bob suspended on the positioning axis uses gravity to determine the pipe's center of gravity. Because the relative position of the positioning axis and the main support rod is fixed, the center of gravity determined by the plumb bob and the inner diameter data measured by the rangefinder are in the same coordinate system. The measurement results are correlated and accurate, providing precise positioning and dimensional references for pipe installation, contributing to improved installation accuracy and quality.

[0031] To address the issue of insufficient measurement accuracy during pipeline measurement, this embodiment provides an implementation method.

[0032] In one embodiment, the measuring unit further includes a level 404, which is disposed on the main support rod 101.

[0033] Using the above-mentioned device, the main support rod is kept level by setting a level, which provides a stable and reliable reference for the measurement of the distance measuring instrument and the plumb line. The distance measuring instrument accurately measures the inner diameter of the pipe, ensuring that the pipe size meets the design requirements and avoiding problems such as loose pipe connection or leakage caused by pipe diameter error.

[0034] To address the issue of different pipe diameters requiring different support device lengths in pipe support systems, this embodiment provides an implementation method.

[0035] In one embodiment, the branch support 300 includes an inner support 301, an outer support 302, and a locking member 303. One end of the outer support 302 is disposed on the folding member 103, and the other end is disposed on the inner support 301. The outer support 302 is connected to the branch adjustment member 104. The locking member 303 is disposed at the connection between the outer support 302 and the inner support 301 and is used to position the inner support 301.

[0036] Using the above-mentioned device, the position of the sleeve can be flexibly adjusted by the sleeve adjustment component, thereby changing the angle and support force between the branch support and the inner wall of the pipe. It can effectively meet the installation requirements of pipes with different diameters and wall thicknesses, without the need to customize special support devices for each specification of pipe, thus improving the versatility and applicability of the device.

[0037] To address the issues of insufficient adjustment angle and durability of the branch adjustment component during operation, this embodiment provides an implementation method.

[0038] In one embodiment, the sleeve portion 200 includes a sleeve body 201 and a pivot positioning member 202, the pivot positioning member 202 being disposed on the sleeve body 201 and connected to the branch adjustment member 104.

[0039] The aforementioned device provides a stable and precise installation position for the branch adjustment component by setting a rotating shaft positioning block, ensuring that the branch adjustment component can only rotate in a predetermined direction and angle during operation. As a key component connecting the sleeve and the branch adjustment component, the rotating shaft positioning block bears various transmitted forces, including friction during rotation, component weight, and the reaction force of the pipeline on the supporting structure. Through reasonable design and material selection, the rotating shaft positioning block can effectively distribute and bear these forces, enhancing the connection strength between the sleeve and the branch adjustment component and preventing loosening or damage under high-load operating conditions.

[0040] To address the issues of angle adjustment and durability of folding components during operation, this embodiment provides an implementation method.

[0041] In one embodiment, the main support rod 101 is provided with a thread that mates with the sleeve adjustment member 102, and a positioning plate 105 is also provided. The positioning plate 105 is elastically connected to the folding member 103, so that the folding member 103 can return to its initial state when it is not subjected to external force.

[0042] The aforementioned device, with its positioning plate, provides a stable and precise installation position for the folding component, ensuring that it can only rotate in a predetermined direction and angle during operation. As a key component connecting the folding component and the main support rod, the positioning plate bears various transmitted forces, including friction during rotation, component weight, and the reaction force of the pipeline on the supporting structure. Through reasonable design and material selection, the positioning plate effectively disperses and bears these forces, enhancing the connection strength between the folding component and the main support rod, and preventing loosening or damage under high-load operating conditions. The threaded design allows the sleeve adjustment component to move on the main support rod; any other design that allows the sleeve adjustment component to move on the main support rod falls within this protection scope, such as a groove and positioning device on the main support rod that mates with the sleeve adjustment component.

[0043] To address the issues of needing manual support for the device during its initial setup and determining its height, this embodiment provides an implementation method.

[0044] In one embodiment, a base unit is also included, which is disposed below the main support rod 101; the base unit includes a support 501, a support leg 502 and a telescopic leg 503, one end of the support leg 502 is provided with the support 502 and the other end is provided with the telescopic leg 503.

[0045] Using the above-mentioned device, in different terrain conditions, such as construction sites with uneven ground, slopes, or certain height differences, the height of the telescopic legs can be adjusted to ensure that the main load-bearing rod is always in a horizontal state, providing a stable foundation for the entire support device.

[0046] like Figure 2 As shown, the following description, in conjunction with a preferred embodiment, will illustrate the contents involved in the above embodiments.

[0047] The main support rod 101 is made of materials including but not limited to hollow steel pipes and solid round steel, and is the main load-bearing component of the entire device.

A positioning shaft 402 can also be installed on the other end of the main support rod 101. A plumb bob 403 is installed at the lower end of the positioning shaft 402 to determine the center line of gravity of the pipe. The surface of the main support rod 101 is machined with external threads, and a sleeve adjustment component 102 is installed at the other end. The sleeve adjustment component 102 has internal threads and can be rotated to move the sleeve part 200. The shape of the sleeve adjustment component 102 includes but is not limited to hexagons, which are convenient for wrench turning. A rotating assist wheel can also be installed for quick movement, or a slide groove and a positioner can be installed for movement. A level 404 is also installed on the surface of the main support rod 101 to measure the levelness of the main support rod 101, and a positioning plate 105 is installed on the main support rod 101, which is connected to the folding component 103 through a hinge shaft. The sleeve portion 200 is shaped to match the main support rod 101 and is fitted onto the main support rod 101. It can move along the length of the main support rod 101 under external force. A pivot positioning component 202 is mounted on it, and the pivot positioning component 202 is connected to the branch adjustment component 104. The inner support component 301 and the outer support component 302 form a nested support combination structure. The length of the combination structure can be adjusted by rotating the locking component 303. After adjustment, it can be fixed after tightening the pipe to achieve the required length for reinforcing the pipe. One end of the outer support component 302 is mounted on the folding component 103, and the outer support component 302 is connected to the branch adjustment component 104, which is connected to the pivot. A base unit is also included, located below the main support rod 101. The base unit includes a support 501, a support leg 502, and a telescopic leg 503. One end of the support leg 502 is provided with the support 502, and the other end is provided with the telescopic leg 503. It can be used alone or in combination with other devices. The height of the base unit can be adjusted by adjusting the telescopic leg 503.
