Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for pipeline installation, and in particular to an adjustable-angle temporary pipeline support frame for temporarily supporting, fixing and adjusting the installation elevation of pipelines, and its application method. Background Technology

[0002] In electromechanical installation projects, especially in narrow spaces such as building ceilings and integrated pipe corridors, various pipelines often need to be laid in layers and crisscross. For example Figure 7 As shown, when it is necessary to install, weld, or modify new pipelines above existing lower-level pipelines, it is impossible to directly erect fixed supports from the ground or the lower-level structure because the lower-level pipelines already occupy space. This problem is particularly typical in pipeline renovation projects: the lower-level pipelines have been installed, and sporadic pipeline installation or welding work needs to be carried out above them, but the lower space is completely blocked by existing pipelines, and traditional support structures have nowhere to be anchored. Other temporary methods must be sought to barely achieve temporary placement and elevation adjustment of the new pipelines, which is extremely inconvenient and poses safety hazards.

[0003] Traditional construction methods often involve erecting full-span scaffolding, suspending manual hoists, or setting up temporary support poles. These methods are cumbersome, time-consuming, and labor-intensive, and are difficult to implement in areas with high-density pipelines. They also result in low construction efficiency, high safety risks, and potential damage to existing pipelines.

[0004] Existing temporary support devices are mostly fixed brackets or simple blocks, which cannot flexibly adapt to the needs of different pipe diameters, different installation elevations, and changes in pipeline routes. Especially when there is a height difference or horizontal angle between upper and lower pipelines, conventional support methods are difficult to achieve quick and stable temporary positioning and precise elevation adjustment, affecting the accuracy of pipeline connection and welding quality, and also increasing the difficulty and danger of high-altitude operations.

[0005] Therefore, there is an urgent need for a temporary pipe support device that is lightweight, widely applicable, quick to install, and flexibly adjustable in height and angle, in order to solve the technical challenges of temporary support and position adjustment during the construction of multi-layer pipes in narrow spaces. Summary of the Invention

[0006] The purpose of this invention is to provide a solution for a quick, stable, and precise adjustable temporary pipe support frame and its application method in installation environments with multiple layers of pipelines and limited space, especially in situations where existing pipelines obstruct the space and it is impossible to set up supports in traditional locations.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An angle-adjustable temporary pipe support frame is used to temporarily support and position a newly installed pipe above an existing pipe, including an upper pipe support, a lower pipe support, and a support adjustment assembly connecting the lower pipe support and the upper pipe support.

[0009] The lower pipe support is used to clamp the existing pipe;

[0010] The upper pipe support is used to clamp the pipe to be installed;

[0011] The support adjustment assembly includes a base, a support rod, an angle control device, and an angle adjustment device;

[0012] The base is connected to the lower tube support;

[0013] The lower end of the support rod is driven to be connected to the angle control device, which is located on the base and is used to provide a drive for the support rod to swing left and right, so that the support rod body tilts.

[0014] The upper end of the support rod is connected to the upper tube support through the angle adjustment device, which is used to convert the movement of the tilted upper end of the support rod into a positional offset of the upper tube support in the horizontal plane.

[0015] Preferably, the angle control device includes a motor gearbox and a sliding seat driven therefrom;

[0016] The motor gearbox is mounted on the base; the sliding seat is connected to the output end of the motor gearbox, and the motor gearbox drives the sliding seat to swing left and right on the base.

[0017] Preferably, the angle adjustment device includes a connecting plate and a sliding adjustment assembly;

[0018] The lower end of the support rod is fixedly connected to the sliding seat through a connecting plate, and the support rod body tilts due to the left and right swing of the sliding seat.

[0019] The upper end of the support rod is connected to the upper tube support through the sliding adjustment component. When the support rod body tilts, the upper end of the support rod forms an angle with the bottom of the upper tube support through the sliding adjustment component, thereby causing the upper tube support to shift horizontally.

[0020] Preferably, the sliding adjustment assembly includes a rectangular slide groove limiting housing, a slide rail, and a hinge; the rectangular slide groove limiting housing is disposed on the top of the upper tube support, the slide rail is embedded in the rectangular slide groove limiting housing, a slider is sleeved on the slide rail, and the upper end of the support rod is hinged to the slider via a hinge; when the support rod body tilts, the top of the support rod moves horizontally on the slide rail via the slider, thereby achieving that when the support rod body tilts, the upper tube support connected to it maintains a horizontal position and moves horizontally along with the support rod.

[0021] Preferably, the support rod is composed of two double hydraulic rods, which are equipped with a hydraulic system that drives their piston rods to extend and retract synchronously. This system is used to independently drive the upper tube support to move up and down, and to adaptively adjust the height during tilting, thereby maintaining the upper tube support in a horizontal positional shift.

[0022] Preferably, the lower tube support includes a first semi-circular ring clamp, a second semi-circular ring clamp, a U-shaped lock, an irregular spring, and a spring winding block;

[0023] Both the first and second semicircular ring clamps have locking holes at one end, and the U-shaped buckle is connected to the ends of the first and second semicircular ring clamps through the locking holes for locking.

[0024] The other ends of the first semi-circular ring clamp and the second semi-circular ring clamp are respectively provided with cylindrical connecting parts. The cylindrical connecting parts are rotatably connected to the base, so that the first semi-circular ring clamp and the second semi-circular ring clamp are symmetrically arranged and open outwards respectively, for clamping existing pipes of different diameters.

[0025] The spring winding block is located inside the base. One end of the irregular spring is fixed to the side of the cylindrical connecting part, and the other end is fixedly sleeved on the spring winding block so that the first semi-circular ring clamp and the second semi-circular ring clamp maintain an outward opening elastic force.

[0026] Preferably, the lower pipe support further includes a plurality of hydraulic pipe clamps evenly distributed on the inner walls of the first semi-circular ring clamp and the second semi-circular ring clamp, and anti-wear blocks disposed on the hydraulic pipe clamps;

[0027] Each of the hydraulic pipe clamps has an anti-wear block at the end of its piston rod. The anti-wear block is used to increase friction with the clamped pipe, prevent slippage, and avoid the metal piston rod scratching the pipe.

[0028] Preferably, the upper tube support includes a movable tube support housing, a movable clamp, and two oppositely arranged fixed clamps;

[0029] The two fixed clamps are fixed to the top of the movable pipe support housing and close to the edge of the movable pipe support housing; the movable clamp is movably disposed on the movable pipe support and driven by a ball screw mechanism. The ball screw mechanism drives the movable clamp to move closer to or away from the two fixed clamps, thereby forming a clamping opening with a variable spacing, which is used to adapt to and clamp pipes of different diameters to be installed.

[0030] Preferably, the movable clamp is a movable wedge clamp, and the fixed clamp is a fixed wedge clamp; the clamping surfaces of the movable wedge clamp and the fixed wedge clamp are wedge-shaped surfaces.

[0031] This invention also provides a method for applying an angle-adjustable temporary pipe support, comprising the following steps:

[0032] Step S1: On-site preparation and equipment inspection

[0033] Step S11: Investigate the construction site, measure and record the spatial relative positions of existing pipelines and pipelines to be installed;

[0034] Step S12: Prepare and check the functionality of each component of the temporary pipe support frame according to the specifications of the pipe to be clamped;

[0035] Step S13: Clean the surface of the existing pipe at the location where the pipe support is to be installed, ensuring that it is free of dirt and burrs;

[0036] Step S2: Install and secure the pipe support to the existing pipeline.

[0037] Step S21: The operator holds the base and, with the help of the elastic force provided by the irregular spring, opens the first semi-circular ring clamp and the second semi-circular ring clamp symmetrically outward;

[0038] Step S22: Insert the open lower pipe support horizontally into the existing lower pipe from the side, so that the pipe is placed in the opening formed by the two semi-circular ring clamps;

[0039] Step S23: Loosen the first semicircular ring clamp and the second semicircular ring clamp, so that they can initially wrap around the existing pipe under the action of the rebound force of the irregular spring and its own weight;

[0040] Step S24: Pass the U-shaped buckle through the corresponding locking holes on the first semi-circular ring clamp and the second semi-circular ring clamp and lock it to initially fix the lower pipe support on the existing pipe;

[0041] Step S25: According to the pipe specifications, activate the hydraulic pipe clamp to drive the anti-wear block at its end to press against the outer wall of the existing pipe, achieving the final stable clamping. At this time, the anti-wear block can prevent damage to the pipe surface.

[0042] Step S3: Coarse and fine adjustment of the spatial position of the pipe to be installed

[0043] Step S31: Height adjustment: Synchronously control the extension or retraction of the dual hydraulic rods to smoothly raise or lower the upper pipe support and the pipe it holds, and roughly adjust it to near the target elevation;

[0044] Step S32: Horizontal Angle and Position Adjustment: Start the motor gearbox of the angle control device to drive the sliding seat to make precise left and right displacement; the sliding seat drives the lower end of the double hydraulic rod fixed thereto to move, so that the upper end of the double hydraulic rod can slide adaptively along the slide rail through the hinged slider. The structure embedded in the rectangular slide groove limiting housing ensures the stability of the movement and limits the sliding of the slider.

[0045] At this time, the ends of the double hydraulic rods and the movable pipe support housing of the upper pipe support are angled due to the inclination of the double hydraulic rods, and the extension or contraction is adaptively adjusted; the angle adjustment device pushes the upper pipe support to swing left and right, thereby adjusting the horizontal angle and lateral position of the upper pipe.

[0046] Step S33: Repeat the above fine-tuning operations for height and angle, observe the measuring instrument, until the pipe to be installed reaches the precise three-dimensional spatial coordinates and orientation required by the design drawings;

[0047] Step S4: Place and clamp the pipe to be installed on the upper pipe support.

[0048] Step S41: Control the retraction of the dual hydraulic rods to adjust the upper tube support to a suitable initial height for easy operation;

[0049] Step S42: Control the ball screw motor to reverse, drive the screw to rotate, and move the nut and the movable wedge clamp connected to it away from the fixed wedge clamp to open the clamping space of the upper tube support;

[0050] Step S43: Hang or manually place the upper pipe to be installed onto the movable pipe support of the upper pipe support, so that it is tightly attached to the inside of the two fixed wedge clamps;

[0051] Step S44: Control the ball screw motor to rotate forward, drive the movable wedge clamp to move towards the two fixed wedge clamps, and use the guiding and self-locking characteristics of the wedge structure until it works with the two fixed wedge clamps to firmly hold the pipe to be installed from both sides.

[0052] Step S5: Pipe fixing and subsequent work

[0053] Step S51: After confirming that the pipe position fully meets the requirements, maintain the pressure of the double hydraulic rods to maintain the support state;

[0054] Step S52: Construction personnel carry out subsequent work such as installation, alignment, and welding of the formal pipe supports and hangers. This temporary pipe support frame provides stable and reliable temporary support throughout the entire operation.

[0055] Step S6: Disassembly and Recycling

[0056] Step S61: After the permanent support or connection of the pipeline is completed and it is confirmed that it can support itself, loosen the movable wedge clamp of the upper pipe support according to the operation in step S42 to release the clamp on the installed pipeline.

[0057] Step S62: Control the retraction of the dual hydraulic rods to move the upper tube support away;

[0058] Step S63: Perform the reverse operation of steps S24 and S25 to release the pressure of the hydraulic pipe clamp, open the U-shaped lock, and remove the lower pipe support from the existing pipe;

[0059] Step S64: Clean and maintain the temporary pipe support frame, and store it for future use.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] (1) Convenient and efficient construction: Through modular and integrated design, this invention integrates support, clamping and multi-directional adjustment functions, enabling a single person to quickly "install and use" and dismantle, saving the cumbersome process of traditional scaffolding erection and hanging equipment, and significantly shortening the construction cycle.

[0062] (2) Strong spatial adaptability: The present invention achieves independent and synchronous precise adjustment of height and horizontal angle through a support adjustment component consisting of a motor-driven slider, double hydraulic rods and a slide rail-hinge structure. This allows the device to flexibly adapt to narrow spaces with crisscrossing pipes and varying heights, fundamentally solving the problem of not being able to set up traditional supports due to spatial obstruction.

[0063] (3) Stable bearing and reliable clamping: The present invention achieves adaptive locking and stable bearing on existing pipelines by setting a lower pipe support with a spring-assisted opening mechanism, a U-shaped lock and a hydraulically driven clamping unit; at the same time, by adopting an upper pipe support that combines a wedge surface and a ball screw drive, adaptive centering and firm clamping of pipelines of different diameters are achieved, providing a stable and non-slip temporary support point for the pipeline.

[0064] (4) Precise adjustment and accurate positioning: This invention achieves fine and continuous adjustment of the spatial posture of the pipeline by linking the independent lifting drive of the dual hydraulic rods with the horizontal angle adjustment driven by the slider mechanism, ensuring the alignment accuracy of welding and installation, and effectively improving the construction quality.

[0065] (5) Good versatility and wide range of applications: The upper and lower pipe supports of this invention are designed differently for different functions and can adapt to various pipe diameters; the adjustment mechanism has a wide range of continuous adjustment capabilities, so that one set of equipment can meet the temporary support needs of pipes at different elevations and in different directions, reducing the investment in special equipment.

[0066] (6) High safety and significant comprehensive benefits: The invention has a lightweight structure and is stable to install, which fundamentally reduces the safety risks caused by high-altitude scaffolding operations and temporary hoisting. At the same time, the device can be reused, avoiding the consumption of a large amount of temporary materials, and has outstanding economic and environmental benefits.

[0067] This invention, through the synergistic innovation of modular integrated design and a multi-functional adjustment mechanism, effectively solves the technical challenge of temporarily supporting and precisely positioning newly installed pipelines above existing pipelines in confined spaces. Compared with traditional methods such as erecting scaffolding or using slings, this device achieves a unified approach of rapid assembly and disassembly, stable load-bearing capacity, multi-directional precision adjustment, and wide adaptability. The spring-assisted and hydraulic locking design of the lower pipe support ensures installation efficiency and foundation stability, while the wedge-shaped centering and screw drive of the upper pipe support ensure reliable pipe clamping. The adjustment system, composed of a dual hydraulic rod and a slider hinge mechanism, provides the device with independent and synchronous adjustment capabilities in both height and horizontal angle. In summary, this invention has significant advantages in construction efficiency, spatial adaptability, operational safety, adjustment accuracy, and overall economic benefits, providing an advanced and reliable specialized construction equipment for electromechanical installation, especially pipeline renovation projects.

[0082] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0083] like Figures 1 to 6 As shown, this invention discloses an angle-adjustable temporary pipe support frame for temporarily supporting and positioning newly installed pipes above existing pipes. It includes an upper pipe support 500, a lower pipe support 100, and a support adjustment assembly connecting the lower pipe support 100 and the upper pipe support 500.

[0084] The lower pipe support 100 is used to clamp an existing pipe, and includes a first semi-circular ring clamp 101, a second semi-circular ring clamp 102, a U-shaped lock 103, an irregular spring 104, and a spring winding block 201.

[0085] Both the first semicircular ring clamp 101 and the second semicircular ring clamp 102 have locking holes at one end. The U-shaped buckle 103 connects the ends of the first semicircular ring clamp 101 and the second semicircular ring clamp 102 through the locking holes to lock them.

[0086] The other ends of the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102 are respectively provided with cylindrical connecting parts 105. The cylindrical connecting parts 105 are rotatably connected to the base 200, so that the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102 are symmetrically arranged and open outwards respectively, for clamping existing pipes of different diameters.

[0087] A spring-encircling block 201 is disposed inside the base 200. One end of the irregularly shaped spring 104 is fixed to the side of the cylindrical connecting part 105, and the other end is fixedly sleeved on the spring-encircling block 201, so that the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102 maintain an outwardly opening elastic force. (The arrangement of the irregularly shaped spring 104 belongs to a similar structure to an open clamp, which is prior art and not a technical solution of this application, so it will not be discussed further here.)

[0088] Furthermore, in this embodiment, the lower pipe support 100 also includes a plurality of hydraulic pipe clamps 106 evenly distributed on the inner walls of the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102, and anti-wear blocks 107 disposed on the hydraulic pipe clamps 106.

[0089] Each hydraulic pipe clamp 106 is essentially a small single-acting hydraulic cylinder with its cylinder body embedded in a semi-circular ring clamp. The end of its piston rod is provided with an anti-wear block 107, which is used to increase the friction with the clamped pipe, prevent slippage, and avoid the metal piston rod scratching the pipe.

[0090] The anti-wear block 107 is made of elastic wear-resistant materials such as engineering plastics or rubber and is replaceably connected to the end of the piston rod. After the U-shaped locking buckle 103 has completed its initial locking, an external hydraulic power source can be connected to simultaneously supply oil to each hydraulic clamp 106, driving its piston rod to extend synchronously and pushing the anti-wear block 107 tightly against the outer wall of the pipe, thereby providing a strong and uniform final clamping force. The function of the anti-wear block 107 is to increase friction, prevent slippage, and avoid direct contact between the metal piston rod and the pipe's anti-corrosion layer.

[0091] The upper pipe support 500 is used to clamp the pipe to be installed. The upper pipe support 500 includes a movable pipe support housing 501, a movable wedge clamp 502, and two oppositely arranged fixed wedge clamps 503.

[0092] Two fixed wedge clamps 503 are fixed to the top of the movable pipe support housing 501 and close to the edge of the movable pipe support housing 501; the movable wedge clamp 502 is movably disposed on the movable pipe support housing 501 and driven by a ball screw mechanism. The ball screw mechanism drives the movable wedge clamp 502 to move closer to or away from the fixed wedge clamp 503, thereby forming a clamping opening with a variable spacing. The clamping surface of the clamping opening is a wedge-shaped surface, which is used to adapt to and clamp pipes of different diameters to be installed.

[0093] The support adjustment assembly includes a base 200, a support rod, an angle control device 300, and an angle adjustment device 400.

[0094] The base 200 is connected to the lower tube support 100.

[0095] In this embodiment, the support rod adopts two double hydraulic rods 401. The double hydraulic rods 401 are equipped with a hydraulic system that drives their piston rods to extend and retract synchronously. This system is used to independently drive the upper tube support 500 to perform lifting and lowering movements, and to adaptively adjust the height during tilting, thereby maintaining the horizontal positional shift of the upper tube support 500.

[0096] The angle control device 300 includes a motor gearbox 301 and a sliding seat 302 driven by it. The motor gearbox 301 is mounted on the base 200; the sliding seat 302 is connected to the output end of the motor gearbox 301, and the motor gearbox 301 drives the sliding seat 302 to swing left and right on the base 200. The motor gearbox 301 drives the sliding seat 302 to move through a gear rack or lead screw and nut pair. (The operation mode of the motor gearbox 301 is prior art and not the technical solution of this application, so it will not be described in detail here.)

[0097] The angle adjustment device 400 includes a connecting plate 403 and a sliding adjustment assembly.

[0098] The lower ends of the two double hydraulic rods 401 are fixedly connected to the sliding seat 302 of the angle control device through the connecting plate 403. The left and right swing of the sliding seat 302 causes the rods of the two double hydraulic rods 401 to tilt.

[0099] The upper ends of the two double hydraulic rods 401 are connected to the upper tube support 500 via a sliding adjustment assembly, such as... Figure 5 As shown, the sliding adjustment assembly includes a rectangular slide groove limiting housing 402, a slide rail 404, and a hinge 405.

[0100] A rectangular sliding groove limiting housing 402 is set on the top of the upper tube support 500. A slide rail 404 is embedded in the rectangular sliding groove limiting housing 402. A slider is sleeved on the slide rail 404. The upper ends of the two double hydraulic rods 401 are hinged to the slider through hinges. When the rods of the two double hydraulic rods 401 are tilted, the upper ends of the two double hydraulic rods 401 form an angle with the bottom of the movable tube support housing 501 of the upper tube support 500 through the sliding adjustment component. The tops of the two double hydraulic rods 401 are horizontally displaced on the slide rail 404 through the slider, so that when the rods of the two double hydraulic rods 401 are tilted, the upper tube support 500 connected to them remains in a horizontal position and moves horizontally with the two double hydraulic rods 401.

[0101] In addition, such as Figure 8As shown, this embodiment also provides an application method for the angle-adjustable temporary pipe support, including the following steps:

[0102] Step S1: On-site preparation and equipment inspection

[0103] Step S11: Investigate the construction site, measure and record the spatial relative positions of the existing pipeline (lower layer pipeline) and the pipeline to be installed (upper layer pipeline);

[0104] Step S12: According to the specifications of the pipe to be clamped, prepare and check whether the functions of each component of the temporary pipe support frame are intact; in particular, check the locking function of the U-shaped lock 103 and the hydraulic pipe clamp 106, as well as whether the operation of the ball screw motor 504, the double hydraulic rod 401 and the angle control device 300 is smooth and effective.

[0105] Step S13: Clean the surface of the existing pipe at the location where the lower pipe support 100 is to be installed, ensuring that there is no dirt or burrs;

[0106] Step S2: Install and secure the pipe support to the existing pipeline.

[0107] Step S21: The operator holds the base 200 and, with the help of the elastic force provided by the irregular spring 104, opens the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102 outward symmetrically.

[0108] Step S22: Insert the open lower pipe support 100 horizontally into the existing lower pipe from the side, so that the pipe is placed in the opening formed by the two semi-circular ring clamps.

[0109] Step S23: Loosen the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102, so that they initially wrap around the existing pipe under the action of the rebound force of the irregular spring 104 and their own weight.

[0110] Step S24: Pass the U-shaped buckle 103 through the corresponding locking holes on the first semi-circular ring clamp 101 and the second semi-circular ring clamp 102 and lock it, so that the lower pipe support 100 is initially fixed on the existing pipe;

[0111] Step S25: According to the pipe specifications, start the hydraulic pipe clamp 106 and drive the anti-wear block 107 at its end to press against the outer wall of the existing pipe to achieve the final stable clamping. At this time, the anti-wear block 107 can prevent damage to the pipe surface.

[0112] Step S3: Coarse and fine adjustment of the spatial position of the pipe to be installed

[0113] Step S31: Height adjustment: Synchronously control the double hydraulic rods 401 to extend or retract, smoothly raise or lower the upper pipe support 500 and the pipe it holds, and roughly adjust it to near the target elevation.

[0114] Step S32: Adjusting the horizontal angle and position: as follows Figure 6 As shown, the motor gearbox 301 of the start angle control device 300 drives the sliding seat 302 to make precise left and right displacements; the sliding seat 302 drives the lower end of the double hydraulic rod 401 fixed thereto to move, so that the upper end of the double hydraulic rod 401 connected by the hinge 405 can slide adaptively along the slide rail 404. The structure embedded in the rectangular slide groove limiting housing 402 ensures the stability of the movement and limits the sliding of the slider.

[0115] At this time, the ends of the double hydraulic rods 401 and the movable pipe support housing 501 of the upper pipe support 500 are angled due to the inclination of the double hydraulic rods 401, and their extension or contraction is adaptively adjusted; the angle adjustment device 400 pushes the upper pipe support 500 to swing left and right, thereby adjusting the horizontal angle and lateral position of the upper pipe.

[0116] Step S33: Repeat the above fine-tuning operations for height and angle, observe the measuring instrument, until the pipe to be installed reaches the precise three-dimensional spatial coordinates and orientation required by the design drawings;

[0117] Step S4: Place and clamp the pipe to be installed on the upper pipe support.

[0118] Step S41: Control the retraction of the double hydraulic rods 401 to adjust the upper tube support 500 to a suitable initial height for easy operation;

[0119] Step S42: Control the ball screw motor 504 to reverse, drive the screw 505 to rotate, and drive the nut 506 and the movable wedge clamp 502 connected thereto to move away from the fixed wedge clamp 503, so as to open the clamping space of the upper tube support 500.

[0120] Step S43: Hoist or manually place the upper pipe to be installed onto the movable pipe support housing 501 of the upper pipe support 500, so that it is tightly attached to the inner side of the two fixed wedge clamps 503.

[0121] Step S44: Control the ball screw motor 504 to rotate forward, drive the movable wedge clamp 502 to move towards the two fixed wedge clamps 503, and use the guiding and self-locking characteristics of the wedge structure until it works with the two fixed wedge clamps 503 to firmly hold the pipe to be installed from both sides.

[0122] Step S5: Pipe fixing and subsequent work

[0123] Step S51: After confirming that the pipe position fully meets the requirements, maintain the pressure of the double hydraulic rods 401 to maintain the support state;

[0124] Step S52: Construction personnel carry out subsequent work such as installation, alignment, and welding of the formal pipe supports and hangers. This temporary pipe support frame provides stable and reliable temporary support throughout the entire operation.

[0125] Step S6: Disassembly and Recycling

[0130] This invention, through the synergistic innovation of modular integrated design and a multi-functional adjustment mechanism, effectively solves the technical challenge of temporarily supporting and precisely positioning newly installed pipelines above existing pipelines in confined spaces. Compared with traditional methods such as erecting scaffolding or using slings, this device achieves a unified approach of rapid assembly and disassembly, stable load-bearing capacity, multi-directional precision adjustment, and wide adaptability. The spring-assisted and hydraulic locking design of the lower pipe support ensures installation efficiency and foundation stability, while the wedge-shaped centering and screw drive of the upper pipe support ensure reliable pipe clamping. The adjustment system, composed of a dual hydraulic rod and a slider hinge mechanism, provides the device with independent and synchronous adjustment capabilities in both height and horizontal angle. In summary, this invention has significant advantages in construction efficiency, spatial adaptability, operational safety, adjustment accuracy, and overall economic benefits, providing an advanced and reliable specialized construction equipment for electromechanical installation, especially pipeline renovation projects.
