Description

Technical Field

[0001] This invention relates to the field of pipeline support technology, and in particular to an adjustable bracket and fastening assembly for pipeline installation and its usage method. Background Technology

[0002] In the construction of some infrastructure projects or buildings, facilities such as drainage, fire protection, heating, ventilation, and air conditioning are required, resulting in a complex network of pipes. Effective support and fixation are necessary during pipe installation, but current technologies still have the following shortcomings: 1. Traditional fastening clamps use a fixed specification design. When the outer diameter of the pipe changes, the existing fastening device has difficulty maintaining an effective clamping force, which affects the stability of the system.

[0003] 2. Once the piping system is installed, certain sections may be obstructed by supports and fixed pipe clamps, making it difficult to conduct comprehensive maintenance during the upkeep phase and posing a safety hazard.

[0004] 3. Existing technology employs a construction process of first fixing the supports (installing them to the ground with bolts) and then laying the pipeline. Because positional deviations are prone to occur during pipeline laying, when the actual height and angle do not match the pre-installed supports, the support height / position needs to be adjusted, increasing the time and cost of secondary operations.

[0005] To address the aforementioned problems, this invention proposes an adjustable bracket and fastening assembly for pipeline installation, as well as a method for using them. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing mounting brackets, such as the inability to adjust the height, position, and angle of the mounting brackets, the obstruction of parts of the pipe by the mounting brackets and their fastening clamps, and the inability of the fastening clamps to fasten pipes of different diameters. The invention proposes an adjustable bracket and fastening assembly for pipe network installation, as well as a method for using the fastening assembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The fastening assembly includes two support seats and a U-shaped fastening clamp. The top sides of the two support seats are provided with slots, and the two ends of the U-shaped fastening clamp extend into the two slots respectively. The fastening structure, located within the support base and the U-shaped fastening clamp, is used to move the U-shaped fastening clamp downwards to clamp and fix the pipeline.

[0008] In one possible design, the fastening structure includes two trapezoidal grooves disposed within a U-shaped fastening clamp. The inner walls of the two grooves on their opposite sides are each provided with a sliding groove. A second lead screw is rotatably connected to the inner walls of the two sliding grooves on their adjacent sides. The opposite ends of the two second lead screws pass through their respective grooves and extend to one side of the support base. A right-angled trapezoidal block, threadedly connected to the second lead screw, is slidably connected to each of the two sliding grooves, and the right-angled trapezoidal block engages with the trapezoidal groove to drive the U-shaped fastening clamp downwards. The bottom inner walls of the two trapezoidal grooves are provided with clearance grooves to allow space for the second lead screw. The two U-shaped fastening clamps are then secured to the pipe, with both ends inserted into their respective grooves. During insertion, the clearance grooves allow space for the second lead screw, which is then driven to rotate. The second lead screw causes the right-angled trapezoidal block to extend into the trapezoidal groove, and the right-angled trapezoidal block engages with the trapezoidal groove to press the U-shaped fastening clamp downwards, thus initially clamping and fixing the pipe.

[0009] In one possible design, the U-shaped fastening clamp has an arc-shaped hydraulic groove inside. A hydraulic cylinder is fixed to the top of the U-shaped fastening clamp, and the bottom end of the hydraulic cylinder extends into the arc-shaped hydraulic groove. A first piston block is slidably connected inside the hydraulic cylinder. A third lead screw is rotatably connected to the top of the first piston block. The top of the third lead screw is threaded through the top of the hydraulic cylinder. The third lead screw cooperates with the first piston block to squeeze hydraulic oil into the arc-shaped hydraulic groove. The bottom inner wall of the arc-shaped hydraulic groove has multiple circular hydraulic grooves. A second piston block is slidably connected to each of the multiple circular hydraulic grooves. A piston rod is fixed to the bottom end of each of the multiple second piston blocks. The bottom end of each of the multiple piston rods passes through the U-shaped fastening clamp and is fixed with a rubber pressure plate for clamping the pipeline. Rotating the third lead screw drives the first piston block to move downward. Under the action of hydraulic oil, the second piston block pushes the piston rod and the rubber pressure plate downward to clamp the pipeline, further increasing the stability of pipeline clamping.

[0010] An adjustable bracket for pipeline installation includes the fastening components described above, and also includes a base. A lifting seat is provided above the base. A fixed column is slidably connected to the top of the lifting seat. A rotating column is rotatably connected to the top of the fixed column. A mounting seat is fixed to the top of the rotating column. Both of the support seats slide on the top of the mounting seat. The first adjustment structure is located inside the base and the lifting seat, and is used to adjust the height and position of the mounting seat; A movable structure, set within the mounting base and support base, is used to drive the support base to move and expose the part to be inspected; An angle adjustment structure is installed inside the fixed column and the rotating column to adjust the deflection angle of the mounting base.

[0011] In one possible design, the first adjustment structure includes two guide rods fixed to the top of the base. Two threaded rods rotatably extend from the top of the base, with the tips of both guide rods slidingly penetrating the lifting seat and the tips of both threaded rods threadedly penetrating the lifting seat. The top of the lifting seat has a sliding groove, within which a first lead screw is rotatably connected, with one end of the first lead screw extending rotatably to one side of the lifting seat. A sliding block threadedly connected to the first lead screw is slidably connected within the sliding groove, with the top of the sliding block fixed to the bottom of the fixed column. A wrench, in conjunction with one of the hexagonal blocks, drives the threaded rods to rotate. The two threaded rods are connected by a synchronous pulley and a synchronous belt, rotating synchronously to adjust the height of the lifting seat and support seat to accommodate pipe laying. When the lateral position of the mounting seat needs adjustment, the rotation of the first lead screw drives the sliding block to move the fixed column and mounting seat to accommodate pipe deviations.

[0012] In one possible design, the movable structure includes two V-shaped brackets fixed to both ends of the mounting base. A fixing rod is fixed between the two V-shaped brackets and slides through the two support seats. A bidirectional lead screw is rotatably connected between the two V-shaped brackets, with one end of the bidirectional lead screw rotatably passing through one of the V-shaped brackets. The two support seats are respectively threaded onto the positive and negative thread sections of the bidirectional lead screw. Each of the two support seats has multiple rotating grooves, and rubber wheels are rotatably connected to each of the multiple rotating grooves. These rubber wheels are used to support the bottom of the pipe and to reduce the friction between the support seat and the pipe when the support seat moves. Each of the two support seats has an arc-shaped groove that communicates with the multiple rotating grooves. An arc-shaped plate that mates with the rubber wheel is slidably connected to each of the two arc-shaped grooves for braking the rubber wheel. Multiple lifting columns are fixed to the bottom of each of the two arc-shaped plates, and the bottom ends of the multiple lifting columns extend to the bottom of the support seat. The top of the mounting base has multiple... A rectangular groove has a wedge-shaped block fixed to its inner wall on the side away from the V-shaped frame. The bottom end of the lifting column extends into the rectangular groove. The bottom of the lifting column on the side away from the V-shaped frame has an inclined surface, which cooperates with the wedge-shaped block to drive the arc plate upward and brake the rubber wheel. When it is necessary to inspect the obstructed part of the pipeline, the third screw is rotated to drive the first piston block upward. The second piston block and the rubber pressure plate move upward under the action of hydraulic oil, releasing the clamping of the pipeline. Then, the double screw is driven to rotate, causing the two support seats to move to both sides. At the same time, after the lifting column loses the pressure of the wedge-shaped block, the arc plate moves downward under the action of gravity, releasing the braking of the rubber wheel by the arc plate. As the support seats move, the rubber wheel rotates under the action of the outer wall of the pipeline until the previously obstructed part is exposed for easy inspection. Conversely, the two support seats can converge to brake the rubber wheel, preventing the pipeline from shifting under the action of the rubber wheel during the later clamping process.

[0013] In one possible design, the angle adjustment structure includes a circular groove at the top of a fixed column, with an internal gear ring fixed to the inner wall of the bottom of the groove. A lifting rod slides longitudinally through the rotating column, and the bottom end of the lifting rod extends into the circular groove and is fixed with a gear that meshes with the internal gear ring. A tension spring is fixed between the top of the gear and the bottom of the rotating column, and the tension spring is sleeved on the outer wall of the lifting rod to drive the gear to move upward and disengage from the internal gear ring. The mounting base has a clearance hole located between two support seats, and the top end of the lifting rod extends into the clearance hole and is fixed with a... An isosceles trapezoidal block, which engages with two support seats, is used to compress the lifting rod and the gear to move downwards. When it is necessary to deflect the support seats, a double-acting screw is driven to rotate. The double-acting screw drives the two support seats to move away from each other, releasing the compression of the isosceles trapezoidal block. The isosceles trapezoidal block and the gear move upwards under the tension of the tension spring. The gear disengages from the internal gear ring, and at this time, the rotating column can drive the support seats to rotate to adapt to the laying orientation of the pipeline. Conversely, when the two support seats come together, they can compress the gear back into the internal gear ring, braking the gear and the rotating column.

[0014] In one possible design, a ring is fixed to the bottom of the rotating column, and an annular groove is provided at the top of the fixed column, with the annular groove slidably connected to the ring to increase the stability of rotation between the fixed column and the rotating column.

[0015] In one possible design, the two guide rods and threaded rods are arranged diagonally. The arrangement of the two guide rods and threaded rods can increase the stability of the lifting seat. The two threaded rods are connected by a synchronous pulley and a synchronous belt to drive the lifting seat to move up and down. The top of each of the two threaded rods is fixed with a hexagonal block to facilitate the rotation of the threaded rod.

[0016] This application discloses a method for using an adjustable bracket for pipeline installation, comprising the following steps: S1. Basic installation and coarse positioning: Install the base and lay the pipe. Use a wrench and hexagonal block to drive the threaded rod to rotate, and adjust the height of the lifting seat and support seat to adapt to the pipe laying. Adjust the lateral position of the mounting seat by rotating the first screw to adapt to pipe deviation. S2. Angle adjustment preparation: Drive the bidirectional lead screw to rotate, so that the two support seats move away from each other, release the compression on the isosceles trapezoidal block, disengage the gear from the internal gear ring, and rotate the rotating column and support seats to adapt to the pipeline laying direction; S3. Pipeline positioning and braking: Place the pipe on the support base, and the two-way screw drives the support base to converge, squeezing the isosceles trapezoidal block. The gear is inserted into the internal gear ring to position the rotating column. The lifting column brakes the rubber wheel under the action of the wedge block, which facilitates stable clamping of the pipe later. S4. Primary pipe fixing: The U-shaped fastening clamp is placed on the pipe and inserted into the slot. The second screw drives the right-angled trapezoidal block to extend into the trapezoidal groove, squeezing the U-shaped fastening clamp and initially clamping and fixing the pipe. S5, Secondary hydraulic reinforcement: Rotating the third lead screw drives the first piston block to move downwards, and the second piston block pushes the piston rod and rubber pressure plate downwards under the action of hydraulic oil, further increasing the stability of pipe clamping; S6, Maintenance Mode Switching: Reverse rotation of the third lead screw releases the rubber pressure plate from clamping the pipe, drives the bidirectional lead screw to rotate, moves the support seat to both sides, and releases the brake on the rubber wheel under the action of gravity. The rubber wheel rotates to expose the covered part, making maintenance convenient.

[0017] Beneficial effects: In this invention, two guide rods are fixed to the top of the base, and two threaded rods rotate on the top of the base. The top ends of the guide rods slide through the lifting seat, and the top ends of the threaded rods thread through the lifting seat. The two guide rods and the threaded rods are arranged diagonally. The top of the lifting seat is provided with a fixed column that is slidably connected to a sliding block through a sliding groove. A first screw threadedly connected to the sliding block is provided in the sliding groove. A wrench is used to drive the threaded rod to rotate in cooperation with one of the hexagonal blocks to adjust the height of the lifting seat and the support seat to adapt to the laying of the pipeline. The rotation of the first screw drives the sliding block to move the fixed column and the mounting seat to adapt to the position of the pipeline deviation. In this invention, an internal gear ring is fixed to the bottom inner wall of the circular groove, a gear is fixed to the bottom end of the lifting rod, and an isosceles trapezoidal block is fixed to the top end of the lifting rod. When the two support seats move to the sides, they release the pressure on the isosceles trapezoidal block. Under the tension of the tension spring, the isosceles trapezoidal block and the gear move upward, and the gear disengages from the internal gear ring. At this time, the support seats can be rotated by the rotating column to adapt to the laying orientation of the pipeline. Conversely, when the two support seats come together, they can press the gear back into the internal gear ring, thus braking the gear and the rotating column. In this invention, each of the rotating grooves is rotatably connected to a rubber wheel, and each support base has an arc-shaped groove. An arc-shaped plate is slidably connected within the arc-shaped groove, and multiple lifting columns are fixed to the bottom of each of the two arc-shaped plates. A wedge block is fixed to the inner wall of one side of the rectangular groove. When the two support bases move to the sides, the arc-shaped plate moves downward after the lifting columns are no longer pressed by the wedge block, and the rubber wheel is released from its brake. As the support bases move, the rubber wheel rotates under the action of the outer wall of the pipe until the previously covered part is exposed, facilitating maintenance. Conversely, when the two support bases move together, they can brake the rubber wheel, preventing the pipe from shifting under the action of the rubber wheel during the subsequent clamping process. In this invention, a second lead screw is rotatably connected to one inner wall of the chute, and a right-angled trapezoidal block is slidably connected inside the chute. Both ends of the U-shaped fastening clamp are provided with trapezoidal grooves, and the right-angled trapezoidal block cooperates with the trapezoidal grooves. Driving the second lead screw to rotate causes the right-angled trapezoidal block to extend into the trapezoidal groove, and the right-angled trapezoidal block cooperates with the trapezoidal groove to press the U-shaped fastening clamp downward, thereby enabling the U-shaped fastening clamp to initially clamp and fix the pipe.

[0018] In this invention, the height, position, and angle of the support base can be adjusted according to the laying of the pipeline, so that the support base can provide stable support for the pipeline. The support base and the U-shaped fastening clamp can clamp pipelines of different diameters. In addition, by moving the two support bases away from each other and releasing the brake on the rubber wheel, the previously covered parts can be exposed, which is convenient for maintenance.

[0021] 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.

[0022] Example 1: Refer to Figure 1 and Figure 9 The fastening assembly relates to the field of mounting bracket technology. The fastening assembly mainly includes two anodized 6061-T6 aluminum alloy support bases 17, a U-shaped fastening hoop 39, and a fastening structure.

[0023] Reference Figure 9 and Figure 10 First, slots 33 are provided on both sides of the top of the two support bases 17. These slots are used to receive the two ends of the U-shaped fastening clamps 39. The U-shaped fastening clamps 39 are designed in a U-shape so that they can wrap around and fit against the outer surface of the pipe. During installation, the two ends of the U-shaped fastening clamps 39 extend into the two slots 33 of the support base 17, thereby initially positioning the U-shaped fastening clamps 39. The U-shaped fastening clamps 39 are formed by bending cold-rolled 304 stainless steel strip, with a cross-sectional thickness of 2-5mm and a yield strength ≥205MPa.

[0024] Reference Figure 9 and Figure 10The fastening structure is located within the support base 17 and the U-shaped fastening clamp 39, used to drive the U-shaped fastening clamp 39 downwards to clamp and fix the pipe. Specifically, the fastening structure includes two trapezoidal grooves 38 within the U-shaped fastening clamp 39. These two trapezoidal grooves 38 are located on the inner surface of the U-shaped fastening clamp 39 and are used to cooperate with the subsequent drive mechanism. Simultaneously, the inner walls of the two slots 33 on opposite sides are provided with sliding grooves 34. Two second lead screws 35 are rotatably connected within the sliding grooves 34. One end of each second lead screw 35 passes through the corresponding slot 33 and extends to one side of the support base 17 for easy external operation. The second lead screws 35 are connected to the support base 17 via precision ball bearings (ISO P4 grade). Right-angled trapezoidal blocks 36 are also slidably connected within the sliding grooves 34, and these right-angled trapezoidal blocks 36 are threadedly connected to the second lead screws 35. When the second lead screws 35 rotate, the right-angled trapezoidal blocks 36 slide within the sliding grooves 34. The right-angled trapezoidal block 36 is designed to cooperate with the trapezoidal groove 38. When the right-angled trapezoidal block 36 extends into the trapezoidal groove 38, it will push the U-shaped fastening clamp 39 downward. The bottom inner wall of the trapezoidal groove 38 is provided with a clearance groove 37. When installing the U-shaped fastening clamp 39, the clearance groove 37 provides clearance space for the second lead screw 35, ensuring that the U-shaped fastening clamp 39 can be smoothly inserted into the slot 33.

[0025] Specifically, first, two U-shaped fastening clamps 39 are secured to the pipe, ensuring that both ends of the U-shaped fastening clamps 39 are inserted into their respective slots 33. During insertion, the clearance groove 37 provides clearance for the second lead screw 35. Then, an external tool is used to drive the second lead screw 35 to rotate. The rotation of the second lead screw 35 causes the right-angled trapezoidal block 36 to slide within the slide groove 34 and extend into the trapezoidal groove 38. The cooperation between the right-angled trapezoidal block 36 and the trapezoidal groove 38 presses the U-shaped fastening clamps 39 downward, achieving initial clamping and fixation of the pipe.

[0026] Reference Figure 1 , Figure 2 and Figure 4 An adjustable support for pipeline installation includes a base 1, which serves as the foundation for the entire support, and a lifting seat 2 on top of the base 1. The lifting seat 2 can be vertically raised and lowered on the base 1 to accommodate pipeline installations at different heights. A fixed column 9 is slidably connected to the top of the lifting seat 2, and the fixed column 9 can slide laterally on the lifting seat 2 to adjust the installation position of the pipeline. A rotating column 12 is rotatably connected to the top of the fixed column 9, and the rotating column 12 can rotate freely on the fixed column 9 to adjust the deflection angle of the mounting seat 13. The mounting seat 13 is fixed to the top of the rotating column 12 and is used to install and support the pipeline. Two support seats 17 slide on the top of the mounting seat 13 and can move on the mounting seat 13 to expose the pipeline section to be inspected.

[0027] Reference Figure 2To achieve the vertical lifting of the lifting seat 2 and the lateral sliding of the fixed column 9, a first adjustment structure is provided in the bracket. The first adjustment structure includes two guide rods 3 fixed to the top of the base 1, which guide the vertical movement of the lifting seat 2. Two threaded rods 4 are also rotatably mounted on the top of the base 1, connected to the lifting seat 2 via threaded connections. Rotating the threaded rods 4 drives the lifting seat 2 to rise or fall. The top ends of both guide rods 3 slide through the lifting seat 2, ensuring the stability of the lifting seat 2 during vertical lifting. A sliding groove 6 is provided on the top of the lifting seat 2, with a first lead screw 8 rotatably connected within it. One end of the first lead screw 8 extends rotatably to one side of the lifting seat 2 for easy rotation by the operator. A sliding block 7, threadedly connected to the first lead screw 8, is slidably connected within the sliding groove 6, allowing the sliding block 7 to slide laterally within the sliding groove 6 under the drive of the first lead screw 8. The top of the sliding block 7 is fixed to the bottom of the fixed column 9, allowing the fixed column 9 to move laterally along with the sliding block 7.

[0028] Specifically, when the height of the support needs to be adjusted to accommodate the pipe laying height, the operator can use a wrench in conjunction with one of the hexagonal blocks 5 to drive the threaded rod 4 to rotate. The two threaded rods 4 are connected by a synchronous pulley and synchronous belt drive, so the two threaded rods 4 can rotate synchronously, thereby driving the lifting seat 2 to rise or fall. When the lateral position of the mounting base 13 needs to be adjusted, the operator can rotate the first lead screw 8 to drive the sliding block 7 to move the fixed column 9 and the mounting base 13 to accommodate the pipe deviation.

[0029] Reference Figures 4-7To drive the support base 17 to move and expose the pipe section to be inspected, a movable structure is provided in the bracket. The movable structure includes two V-shaped brackets 14 fixed to both ends of the mounting base 13. A fixing rod 15 is fixed between the two V-shaped brackets 14, sliding through both support bases 17 to ensure the stability of the support base 17 during movement. A double-acting screw 16 is rotatably connected between the two V-shaped brackets 14, with one end of the double-acting screw 16 rotatably passing through one of the V-shaped brackets 14 for easy rotation by the operator. The two support bases 17 are threaded onto the positive and negative thread sections of the double-acting screw 16, so when the double-acting screw 16 rotates, the two support bases 17 move simultaneously in opposite directions. Multiple rotating grooves 32 are provided inside the support base 17, and rubber wheels 21 are rotatably connected within each groove 32. The rubber wheels 21 support the bottom of the pipe and reduce friction between the support base 17 and the pipe during movement. An arc-shaped groove 20 is also provided inside the support base 17, communicating with the multiple rotating grooves 32. An arc-shaped plate 22, which slidably connects to the arc-shaped groove 20 and engages with the rubber wheel 21, is used to brake the rubber wheel 21. Multiple lifting columns 23 are fixed to the bottom of the arc-shaped plate 22, with the bottom ends of the lifting columns 23 extending below the support base 17. The top of the mounting base 13 has multiple rectangular grooves 18, and a wedge block 19 is fixed to the inner wall of the rectangular groove 18 on the side away from the V-shaped frame 14. The bottom ends of the lifting columns 23 extend into the rectangular grooves 18, and an inclined surface 24 is provided on the bottom side of the lifting column 23 away from the V-shaped frame 14. The inclined surface 24 engages with the wedge block 19 to drive the arc-shaped plate 22 upward and brake the rubber wheel 21.

[0030] Specifically, the bidirectional lead screw 16 is driven to rotate, causing the two support seats 17 to move to both sides. During this movement, after the lifting column 23 is released from the pressure of the wedge block 19, the arc plate 22 moves downward under the action of gravity, releasing the brake on the rubber wheel 21. As the support seats 17 move, the rubber wheel 21 rotates under the action of the outer wall of the pipe until the previously obscured part is exposed, facilitating maintenance by the operator. Conversely, when the two support seats 17 converge, the inclined surface 24 of the lifting column 23 is pushed up by the wedge block 19, thereby driving the arc plate 22 to move upward and brake the rubber wheel 21. In this way, during the subsequent clamping of the pipe, displacement of the pipe under the action of the rubber wheel 21 can be avoided.

[0031] Reference Figure 3 , Figure 4 and Figure 8In addition, the bracket is equipped with an angle adjustment structure to adjust the deflection angle of the mounting base 13 to accommodate pipe installation requirements at different angles. The angle adjustment structure includes a circular groove 25 located at the top of the fixed column 9. An internal gear ring 26 is fixed to the inner bottom wall of this circular groove 25, which plays a crucial braking role. A lifting rod 28 slides longitudinally through the rotating column 12, and the bottom end of the lifting rod 28 extends into the circular groove 25, where a gear 27 is fixed. This gear 27 meshes with the internal gear ring 26, forming a reliable transmission mechanism. To drive the gear 27 upward and disengage from the internal gear ring 26, a tension spring 29 is fixed between the top of the gear 27 and the bottom of the rotating column 12. The tension spring 29 is sleeved on the outer wall of the lifting rod 28, providing a continuous upward pulling force to the gear 27. Furthermore, the mounting base 13 is also provided with a clearance hole 30 located between the two support seats 17. The top end of the lifting rod 28 extends into this clearance hole 30, where an isosceles trapezoidal block 31 is fixed. The isosceles trapezoidal block 31 engages with two support seats 17. When the support seats 17 move away from each other, they release the pressure on the isosceles trapezoidal block 31, allowing the isosceles trapezoidal block 31 and gear 27 to move upwards under the tension of the tension spring 29. The gear 27 then disengages from the internal gear ring 26. At this time, the rotating column 12 can drive the support seats 17 to rotate freely to adapt to the pipe's laying orientation. Conversely, when the two support seats 17 converge, they re-press the isosceles trapezoidal block 31, causing the gear 27 to re-engage with the internal gear ring 26, braking the gear 27 and the rotating column 12, ensuring the directional stability of the support seats 17.

[0032] Reference Figure 3 and Figure 8 To increase the stability of rotation between the fixed column 9 and the rotating column 12, a ring 11 is fixed at the bottom of the rotating column 12, and an annular groove 10 is provided at the top of the fixed column 9. The annular groove 10 and the ring 11 are slidably connected, forming a stable rotational support structure.

[0033] Reference Figure 2 In this embodiment, the two guide rods 3 and the threaded rods 4 are arranged diagonally, which increases the stability of the lifting seat 2. The two threaded rods 4 are connected by a synchronous pulley and a synchronous belt, realizing the synchronous rotation of the two threaded rods 4, thereby driving the lifting seat 2 to rise and fall smoothly. To facilitate the rotation of the threaded rods 4, hexagonal blocks 5 are fixed to the top of each of the two threaded rods 4.

[0034] Example 2: Reference Figure 11 and Figure 12 , refer to Figure 11 and Figure 12The U-shaped fastening clamp 39 also has an arc-shaped hydraulic groove 40. A hydraulic cylinder 41 is fixed to the top of the U-shaped fastening clamp 39, and the bottom of the hydraulic cylinder 41 extends into the arc-shaped hydraulic groove 40. A first piston block 43 is slidably connected inside the hydraulic cylinder 41. The first piston block 43 is equipped with a fluororubber (FKM) sealing ring, and a third lead screw 42 is rotatably connected to the top of the first piston block 43. The threaded end of the third lead screw 42 passes through the top of the hydraulic cylinder 41 for easy external operation. Rotating the third lead screw 42 drives the first piston block 43 to move downwards inside the hydraulic cylinder 41. The downward movement of the first piston block 43 squeezes the hydraulic oil in the hydraulic cylinder 41 into the arc-shaped hydraulic groove 40. ISO VG32 hydraulic oil is pre-filled into the hydraulic cylinder 41 and the arc-shaped hydraulic groove 40, with a working pressure range of 0.6-1.2 MPa. Multiple circular hydraulic grooves 44 are provided on the bottom inner wall of the arc-shaped hydraulic groove 40, and each of these circular hydraulic grooves 44 is slidably connected to a second piston block 45. When hydraulic oil enters the arc-shaped hydraulic groove 40, it pushes the second piston block 45 to slide within the circular hydraulic groove 44. A piston rod 46 is fixed to the bottom end of the second piston block 45, and the bottom end of the piston rod 46 passes through a U-shaped fastening clamp 39 and is fixed with a rubber pressure plate 47. When the second piston block 45 slides, it pushes the piston rod 46 and the rubber pressure plate 47 downwards, further clamping the pipe. The design of the rubber pressure plate 47 increases the clamping force and protects the pipe surface from damage.

[0035] A method for using an adjustable bracket for pipeline installation includes the following steps: S1. The base 1 is installed on the ground with bolts, and the pipe is laid. When there is a height deviation between the support seat 17 and the pipe, the threaded rod 4 is driven to rotate by a wrench in conjunction with one of the hexagonal blocks 5. The two threaded rods 4 are connected by a synchronous pulley and a synchronous belt. The two threaded rods 4 rotate synchronously to adjust the height of the lifting seat 2 and the support seat 17 to adapt to the laying of the pipe. When it is necessary to adjust the lateral position of the mounting seat 13, the rotation of the first screw 8 drives the sliding block 7 to move the fixed column 9 and the mounting seat 13 to adapt to the position of the pipe deviation. S2. When it is necessary to deflect the direction of the support seat 17, drive the double-acting screw 16 to rotate. The double-acting screw 16 drives the two support seats 17 to move away from each other. The two support seats 17 release the pressure on the isosceles trapezoidal block 31. The isosceles trapezoidal block 31 and gear 27 move upward under the tension of tension spring 29. The gear 27 disengages from the internal gear ring 26. At this time, the support seat 17 can be rotated through the rotating column 12 to adapt to the laying position of the pipeline. S3. Next, the pipe is placed on top of the two support seats 17. Then, the two support seats 17 are driven to move towards the middle by the two-way screw 16. The two support seats 17 converge and squeeze the isosceles trapezoidal block 31, and drive the gear 27 to insert into the internal gear ring 26 to position the rotating column 12 and the support seat 17, so as to prevent the rotating column 12 from rotating. When moving, the lifting column 23 drives the arc plate 22 to move upward under the action of the wedge block 19 and brakes the rubber wheel 21, thereby ensuring that the support seat 17 and the U-shaped fastening hoop 39 can stably clamp the pipe later. S4. Then, the two U-shaped fastening clamps 39 are clamped onto the pipe, and the two ends of the U-shaped fastening clamps 39 are inserted into the corresponding slots 33 respectively. During the insertion process, the clearance slot 37 makes way for the second screw 35, and then drives the second screw 35 to rotate. The second screw 35 drives the right-angled trapezoidal block 36 to extend into the trapezoidal groove 38, and the right-angled trapezoidal block 36 cooperates with the trapezoidal groove 38 to press the U-shaped fastening clamps 39 downward, so that the U-shaped fastening clamps 39 can initially clamp and fix the pipe. S5. To further increase the clamping of the pipe by the U-shaped fastening clamp 39, the third lead screw 42 is rotated to drive the first piston block 43 to move down, and the second piston block 45 pushes the piston rod 46 and the rubber pressure plate 47 to move down under the action of hydraulic oil to clamp the pipe, thereby further increasing the stability of the pipe clamping. S6. When it is necessary to inspect the obstructed part of the pipeline, rotate the third lead screw 42 in the reverse direction to drive the first piston block 43 to move upward. The second piston block 45 and the rubber pressure plate 47 move upward under the action of hydraulic oil, releasing the clamping of the pipeline. Then drive the double lead screw 16 to rotate, causing the two support seats 17 to move to both sides. At the same time as they move, the lifting column 23 loses the squeezing of the wedge block 19 and the arc plate 22 moves downward under the action of gravity, releasing the brake of the arc plate 22 on the rubber wheel 21. As the support seats 17 move, the rubber wheel 21 rotates under the action of the outer wall of the pipeline until the previously obstructed part is exposed, making it convenient for inspection.
