Description

Technical Field

[0001] This invention relates to the field of fixed support technology, and in particular to a pipe connection fixed support. Background Technology

[0002] Pipeline connection supports are key components in pipeline systems, widely used in petrochemical, power supply, and urban heating industries, playing a crucial role in ensuring the safe and stable operation of pipelines. The supports consist of a cast-in-place concrete base as the foundation, upon which metal supports provide rigid support to bear the weight of the pipeline itself and external loads, ensuring the pipeline maintains its designed position. They also limit displacement caused by thermal expansion and contraction due to temperature changes and transfer internal pressure and external loads to the concrete base.

[0003] However, the following problems exist in the current installation and use of fixed supports: First, the concrete base is constructed in-situ, resulting in significant elevation errors. This makes it difficult to ensure that the final support planes of multiple fixed supports are at the same design height. This inconsistency in the foundation plane leads to severely uneven stress on the support points after pipeline installation. Some supports are too high and bear excessive loads, while others are too low and completely fail to participate in load-bearing, thus weakening the pipeline's compressive and vibration resistance and affecting its service life. Second, the pipeline slides and moves between supports to adjust its position, but this frictional resistance not only makes pipeline movement and adjustment difficult but also causes scratch damage to the pipeline.

[0004] Therefore, the cumbersome installation and adjustment of the bracket, as well as the uneven stress on the pipeline after fixing and the risk of damage, are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention provide a pipe connection fixing bracket to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a pipe connection fixing bracket, including a base and a base mounted thereon; the base is provided with two symmetrical and L-shaped lifting seats, and annular clamps are fixedly installed on the lifting seats by supports. The lifting seats are provided with an adjustment mechanism and a guide mechanism.

[0007] The adjustment mechanism includes a slide groove on the base, a slide seat slidably installed in the slide groove, two lifting seats slidably installed on the corresponding base and slide seat, an annular clamp consisting of two detachably connected parts, two pairs of isosceles triangular push blocks corresponding one-to-one with the lifting seats slidably installed on the base, a wedge-shaped surface that mates with the inclined surface of the push block on the lifting seat, an inverted concave pressure block detachably installed on the annular clamp, an inclined surface that mates with the push block on the pressure block, and a No. 2 bolt threaded on the base for rotatable connection with the slide seat.

[0008] The guiding mechanism includes a slider that is slidably mounted on the vertical section of the lifting seat, two symmetrical support rollers that are rotatably mounted on the slider via a bearing seat, and a drive unit on the base.

[0009] The drive unit adjusts the height of the support roller to align with the pipeline axis; then the ring clamp assembly grips the pipeline and drives the lifting seat to move upward, with the wedge surface and the inclined surface of the push block in close contact to form a self-locking mechanism; tightening the No. 2 bolt drives the slide to move horizontally, and the rolling friction of the support roller achieves non-destructive pipeline connection.

[0010] As a preferred embodiment, the adjustment mechanism further includes a fixing component. The base is provided with fixing components that correspond one-to-one with the lifting seat. Each group of fixing components consists of two shaft plates that are symmetrical about the front and rear of the corresponding lifting seat. Two limiting rods that are symmetrical about the left and right of the corresponding lifting seat are fixedly installed between the two shaft plates in the same group. The pushing block is slidably installed on the corresponding limiting rod.

[0011] As a preferred embodiment, the ends of both the upper and lower parts of the annular clamp are provided with ear plates, and the upper and lower ear plates are connected by a No. 1 bolt. The No. 1 bolt is rotatably connected to the ear plate of the upper part of the annular clamp, and the lower end of the No. 1 bolt moves through the ear plate of the lower part of the annular clamp and is threadedly connected to the corresponding lifting seat.

[0012] As a preferred embodiment, the horizontal section of the pressure block is connected to the upper part of the annular clamp by a No. 4 bolt, and the vertical section of the pressure block is slidably fitted with the ear plate.

[0013] As a preferred embodiment, the driving unit includes a fixed block that is fixedly installed on the upper end of the base and located between two sliders. Two inclined grooves are opened on the opposite surfaces of the two sliders. The left and right ends of the fixed block are provided with slots that correspond one-to-one with the inclined grooves. The driving block is slidably installed in the slots. A guide post that slides through the corresponding inclined groove is fixedly installed on the driving block.

[0014] As a preferred embodiment, the fixing block is threaded with two symmetrical No. 3 bolts, which pass through the fixing block and are rotatably connected to the corresponding two driving blocks.

[0015] As a preferred option, baffles located below the sliders are fixedly installed on the opposite surfaces of the vertical sections of the two lifting seats.

[0016] As a preferred embodiment, the inclined groove slopes downwards and backwards.

[0017] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention effectively solves the problem of uneven force distribution on each support caused by base elevation errors, as well as the problem of difficulty in movement and surface damage to the pipeline caused by sliding friction during adjustment, through the adjustment mechanism and guide mechanism. A small number of bolts are used to achieve adjustable, controllable, and precise locking of the pipeline's height and horizontal position during installation and connection, ensuring the uniformity and stability of the pipeline system support, while reducing the difficulty of installation and adjustment and protecting the pipeline body.

[0018] Second, the present invention uses a wedge-shaped self-locking mechanism composed of a lifting seat, a pushing block, and a pressing block. When tightening the No. 1 bolt to hold the pipeline, it can actively and effectively compensate for the construction elevation error of the concrete base, and steadily lift and lock the pipeline at a uniform design height. This ensures that the support planes of multiple fixed supports are consistent, thereby ensuring that the pipeline load is evenly distributed among the support points, and greatly enhancing the overall load-bearing capacity and vibration resistance of the pipeline system.

[0019] Third, the present invention provides rolling support for the pipeline through a guiding mechanism composed of a slider and a support roller. When the sliding block and the pipeline are moved horizontally and connected by tightening the No. 2 bolt, there is rolling friction between the pipeline and the support roller. This makes the adjustment of the pipeline position easier and smoother, completely avoiding the scratch damage to the outer wall of the pipeline caused by sliding friction, effectively protecting the integrity of the pipeline and extending its service life.

Detailed Implementation

[0029] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, a pipe connection fixing bracket includes a base 10 and a base 11 mounted thereon; the upper end of the base 11 is provided with two symmetrical L-shaped lifting seats 12, and the lifting seats 12 are fixedly installed with ring clamps 13 by supports. The lifting seats 12 are provided with an adjustment mechanism 2 and a guide mechanism 3.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjustment mechanism 2 includes a slide groove on the base 11. A slide seat 20 is slidably installed in the slide groove by a pair of slide rods 200. Two lifting seats 12 are slidably installed on the corresponding base 11 and slide seat 20 by a pair of columns 21. The annular clamp 13 is divided into upper and lower parts and is connected by a bolt 22. Two pairs of pushing blocks 23 corresponding to the lifting seats 12 are slidably installed on the base 11. The pushing blocks 23 are in the shape of isosceles triangles. The lifting seats 12 are provided with wedge-shaped surfaces that cooperate with the inclined surfaces of the pushing blocks 23. The annular clamp 13 is detachably installed with an inverted concave pressure block 24. The vertical section of the pressure block 24 is provided with an inclined surface that cooperates with the pushing blocks 23. A bolt 25 is threaded on the base 11 and is rotatably connected to the slide seat 20.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the guide mechanism 3 includes a slider 30. A slider 30 is slidably installed on the opposite surfaces of the vertical sections of the two lifting seats 12. A V-shaped groove is provided at the upper end of the slider 30. Two symmetrical support rollers 31 are rotatably installed in the V-shaped groove through a bearing seat. A drive unit 4 is provided on the base 11.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, baffles 300 located below sliders 30 are fixedly installed on the opposite surfaces of the vertical sections of the two lifting seats 12.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, the upper and lower ends of the annular clamp 13 are provided with ear plates. The first bolt 22 is rotatably connected to the ear plate of the upper part of the annular clamp 13, and the lower end of the first bolt 22 moves through the ear plate of the lower part of the annular clamp 13 and is threadedly connected to the corresponding lifting seat 12.

[0035] like Figures 1 to 5 As shown, in specific operations, a concrete base 10 is poured at the required location, and anchor bolts (not shown in the figure) for fixing the base 11 are pre-embedded during the pouring process, while a movable groove (not shown in the figure) is reserved. After the base 10 solidifies, the base 11 is fixedly installed on the upper surface of the base 10 using anchor bolts and nuts. Then, the column 21 on the lifting seat 12 is slid through the base 11 and the slide 20, extending into the corresponding movable groove. Then, the slider 30 is driven upward by the drive unit 4, and the slider 30 drives the support roller 31 upward, so that the lowest point of the upper surface of the support roller 31 is higher than the lowest point of the inner wall of the lower part of the annular clamp 13. Then, the height of the support roller 31 is adjusted by the drive unit 4, so that the two pipes are on the same axis.

[0036] After adjustment, install the upper part of the annular clamp 13. The upper inner wall of the annular clamp 13 fits against the pipe. Then, rotate the No. 1 bolt 22. Since its upper part is rotatably connected to the upper ear plate of the annular clamp 13 and its lower end is threadedly engaged with the lifting seat 12, the rotation of the No. 1 bolt 22 will drive the lower part of the annular clamp 13 to move upward, so that it fits against the lower surface of the pipe. Then, install the pressure block 24. During the downward pressing process, its inclined surface and the inclined surface of the pushing block 23 produce a wedge-shaped self-locking effect, thereby reliably restricting the downward movement of the lifting seat 12 and ensuring the stability of the locking and the anti-vibration performance.

[0037] Then, the drive unit 4 drives the slider 30 to move down, and the slider 30 will abut against the corresponding baffle 300 to limit the upward movement of the lifting seat 12, thereby ensuring the stability of the lifting seat 12 after height adjustment. Then, the second bolt 25 is rotated by an external hydraulic wrench. Since the second bolt 25 is threadedly connected to the base 11 and rotates with the slide 20, the rotational movement of the second bolt 25 will be converted into its own axial movement. When the second bolt 25 is rotated, the second bolt 25 is pushed to the left by the thread of the base 11 and pushes the slide 20, which rotates with it, to move to the left in sync. The slide 20 then drives the corresponding pipe to move to the left through the column 21, the lifting seat 12, the support and the ring clamp 13, so that the ends of the two pipes are tightly joined and welded.

[0038] Through the coordinated operation of the above structures, the shortcomings of existing technologies are effectively overcome. Its core advantages are: by combining the independent height adjustment of the support roller 31 with the wedge-shaped self-locking mechanism, the elevation error of the base 10 can be actively and accurately compensated, ensuring that multiple annular clamps 13 bear the load evenly, which greatly improves the stability and safety of the pipeline system; in addition, during the entire pipeline docking and adjustment process, the pipeline is always provided with rolling support by the support roller 31, avoiding the difficulties in movement and damage to the pipeline surface caused by traditional sliding friction, significantly improving installation efficiency and protecting the pipeline body.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, the driving unit 4 includes a fixed block 40 fixedly installed on the upper end of the base 11 and located between two sliders 30. Two inclined grooves 41 are opened on the opposite surfaces of the two sliders 30. The left and right ends of the fixed block 40 are provided with slots corresponding to the inclined grooves 41. A driving block 42 is slidably installed in the slot. A guide post 43 that slides through the corresponding inclined groove 41 is fixedly installed on the driving block 42.

[0040] like Figure 4 As shown, the fixing block 40 is threaded with two symmetrical No. 3 bolts 44, which pass through the fixing block 40 and are rotatably connected to the corresponding two driving blocks 42.

[0041] like Figure 4 As shown, the inclined groove 41 slopes backward from top to bottom.

[0042] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the adjustment mechanism 2 also includes a fixing component. The base 11 is provided with fixing components that correspond one-to-one with the lifting seat 12. Each fixing component consists of two shaft plates that are symmetrical about the front and back of the corresponding lifting seat 12. Two limiting rods that are symmetrical about the left and right of the corresponding lifting seat 12 are fixedly installed between the two shaft plates in the same group. The pushing block 23 is slidably installed on the corresponding limiting rod.

[0043] like Figure 1 , Figure 2 and Figure 6 As shown, the horizontal section of the pressure block 24 is connected to the upper part of the annular clamp 13 by a No. 4 bolt, and the vertical section of the pressure block 24 is slidably fitted with the ear plate.

[0044] like Figures 1 to 6 As shown, in specific operation, the No. 3 bolt 44 is first rotated by an external hydraulic wrench. Since the No. 3 bolt 44 is threadedly connected to the fixed block 40, and rotates with the drive block 42, the rotational movement of the No. 3 bolt 44 is converted into its own axial movement. When the No. 3 bolt 44 is rotated, it is pushed backward by the thread of the fixed block 40. The backward movement of the No. 3 bolt 44 will push the row of drive blocks 42 that rotate with it to move backward synchronously. The backward movement of the drive blocks 42 will drive the corresponding slider 30 to move upward through the cooperation of the guide post 43 and the corresponding inclined groove 41, so that the lowest point of the upper surface of the support roller 31 is higher than the lowest point of the lower inner wall of the annular clamp 13. At this time, the ends of the two pipes can be placed on the corresponding support rollers 31 respectively. Then, the two No. 3 bolts 44 are rotated respectively to drive the corresponding drive blocks 42 to move. The positions of the two pipes are adjusted by the cooperation of the guide post 43 and the inclined groove 41 so that the two pipes are on the same axis.

[0045] After adjustment, use the ring clamp 13 to tighten and fix the pipe, and then install the pressure block 24 with the No. 4 bolt, so that the pressure block 24 moves down and squeezes the push block 23, so as to push the push block 23 to fit tightly against the lifting seat 12, thereby fixing the pipe at the adjusted height.

[0046] Then, bolt 25 drives slide 20 to move, so as to move the corresponding pipe to connect and fit tightly with another pipe. During this movement, displacement is achieved through rolling friction between the pipe and the support roller 31, which significantly reduces the moving resistance. This ensures the smoothness of pipe movement and effectively reduces wear on the outer surface of the pipe, thereby extending the service life of the pipe. Finally, slide 30 is moved downward, so that the support roller 31 completely descends and disengages from the pipe. Subsequently, slide 30 fully contacts baffle 300. At this time, the entire weight and load of the pipe is finally borne by the ring clamp 13 that is fully clamped to it, and is transmitted to base 10 through support, lifting seat 12, pushing block 23 and base 11. This design completely restricts the displacement of lifting seat 12 in multiple directions, including vertical and horizontal, thereby achieving high-quality and stable support for the pipe and further ensuring the long-term safe use of the pipe. Finally, the exposed parts are rust-proofed to facilitate subsequent maintenance and replacement and extend the service life of the parts. Then, following the above operation, the remaining pipes are connected and supported in sequence from left to right.
