Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fixing support, in particular to a pipeline connecting fixing support. BACKGROUND

[0002] The pipeline connecting fixing support is a key component in the pipeline system, which is widely used in the fields of petroleum and chemical industry, power supply and city heating, and plays a vital role in ensuring the safe and stable operation of the pipeline. The fixing support is based on the concrete base cast on site, and the metal support installed thereon provides rigid support to bear the weight of the pipeline itself and external load, ensures the pipeline to maintain the designed position, limits the thermal expansion and contraction displacement of the pipeline caused by temperature change, and transmits the internal pressure and external load to the concrete base.

[0003] However, there are the following problems in the installation and use of the fixing support: first, the elevation error of the concrete base is large during the cast-in-place construction, which makes it difficult to ensure that the final support planes of multiple fixing supports are at the same design height. The inconsistency of the foundation plane makes the stress of each support point of the pipeline after installation uneven, and part of the supports bear excessive load due to being too high, while the other part is completely ineffective due to being too low and cannot participate in bearing, thereby weakening the compression and vibration resistance of the pipeline and affecting the service life of the pipeline. Second, the pipeline slides and rubs between the supports to adjust the position of the pipeline, but such frictional resistance not only makes it difficult to move and adjust the pipeline, but also causes scratching damage to the pipeline.

[0004] Therefore, the complicated installation and adjustment of the support, as well as the uneven stress and damage risk of the pipeline after being fixed, are technical problems that need to be solved by those skilled in the art. SUMMARY

[0005] In view of the above problems, the present application provides a pipeline connecting fixing support to solve the above technical problems.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme: the present application provides a pipeline connecting fixing support, which comprises a base and a base installed thereon; two symmetrical L-shaped lifting seats are arranged on the base, and a ring-shaped clamp is fixedly installed on the lifting seat through a support; an adjusting mechanism and a guide mechanism are arranged on the lifting seat.

[0007] The adjusting mechanism comprises a sliding groove formed on the base, a sliding seat slidably installed in the sliding groove, two lifting seats slidably installed on the corresponding base and sliding seat, an annular clamp comprising upper and lower parts, two pairs of isosceles triangular structure pushing blocks slidably installed on the base and corresponding to the lifting seats, wedge surfaces provided on the lifting seats and matched with the inclined surfaces of the pushing blocks, and a concave-shaped pressing block detachably installed on the annular clamp and matched with the inclined surfaces of the pushing blocks.

[0008] The guide mechanism comprises a sliding block slidably installed on the vertical section of the lifting seat, two symmetrical supporting rollers rotatably installed on the sliding block through an axle seat, and a driving part provided on the base.

[0009] The driving part adjusts the height of the supporting rollers to align with the axis of the pipeline, and then the annular clamp is combined to tightly hold the pipeline and drive the lifting seat to move upward, and the wedge surfaces are tightly matched with the inclined surfaces of the pushing blocks to form self-locking; the second bolt is tightened to drive the sliding seat to move horizontally, and the rolling friction of the supporting rollers is utilized to realize the lossless butt joint of the pipeline.

[0010] As a preferred solution, the adjusting mechanism further comprises a fixing assembly, the base is provided with a fixing assembly corresponding to each lifting seat, each fixing assembly comprises two axis plates symmetrically arranged in front of and behind the corresponding lifting seat, two limiting rods symmetrically arranged in left and right of the corresponding lifting seat are fixedly installed between the two axis plates of the same group, and the pushing block is slidably installed on the corresponding limiting rod.

[0011] As a preferred solution, the end of the upper and lower parts of the annular clamp is provided with an ear plate, the upper and lower ear plates are connected through a first bolt, the first bolt is rotatably connected with the ear plate of the upper part of the annular clamp, and the lower end of the first bolt is movably penetrated through the ear plate of the lower part of the annular clamp and is threadedly connected with the corresponding lifting seat.

[0012] As a preferred solution, the horizontal section of the pressing block is connected with the upper part of the annular clamp through a fourth bolt, and the vertical section of the pressing block is slidably matched with the ear plate.

[0013] As a preferred solution, the driving part comprises a fixed block fixedly installed on the upper end of the base and located between the two sliding blocks, two inclined grooves are formed in the opposite surfaces of the two sliding blocks, a slot is formed in the left and right ends of the fixed block and corresponds to the inclined grooves, a driving block is slidably installed in the slot, and a guide column is fixedly installed on the driving block and slidably penetrates through the corresponding inclined groove.

[0014] As a preferred solution, two left and right symmetrical third bolts are threadedly connected with the fixed block, the third bolts penetrate through the fixed block and are rotatably connected with the corresponding two driving blocks.

[0015] As a preferred solution, the opposite surfaces of the vertical sections of the two lifting seats are fixedly installed with a baffle located below the sliding block.

[0016] As a preferred solution, the chute is inclined rearward from top to bottom.

[0017] The one or more technical solutions in the embodiments of the present application have at least one of the following technical effects: first, the present application effectively solves the problem of uneven force on each support caused by the elevation error of the base, and the problems of movement difficulty and surface damage caused by sliding friction during adjustment of the pipeline, by adjusting the mechanism and the guide mechanism. A small number of bolts can achieve adjustable, controllable and precise locking of the height and horizontal position of the pipeline during installation and docking, 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 wedge-shaped self-locking mechanism composed of the lifting seat, the pushing block and the pressing block can actively and effectively compensate for the construction elevation error of the concrete base when the first bolt is tightened to tightly hold the pipeline, stably lifting and locking the pipeline at a unified design height, so that the support planes of the multiple fixed supports remain consistent, thereby ensuring that each support point evenly shares the pipeline load, greatly enhancing the overall load-bearing and anti-vibration capacity of the pipeline system.

[0019] Third, the guide mechanism composed of the sliding block and the supporting roller provides rolling support for the pipeline. When the second bolt is tightened to drive the sliding seat and the pipeline to move horizontally for docking, the pipeline and the supporting roller are in rolling friction, which makes the position adjustment of the pipeline labor-saving and smooth, completely avoiding the scratching damage of the outer wall of the pipeline caused by sliding friction, effectively protecting the integrity of the pipeline and prolonging its service life.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in combination with the drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0030] As shown in Figure 1 and Figure 2 , a pipe connecting fixed support comprises a base 10 and a pedestal 11 mounted thereon; the upper end of the pedestal 11 is provided with two lifting seats 12 which are symmetrical left and right and have an L-shaped structure, the annular clamp 13 is fixedly installed on the lifting seat 12 through a support, and the adjusting mechanism 2 and the guide mechanism 3 are arranged on the lifting seat 12.

[0031] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the adjusting mechanism 2 comprises a sliding slot opened on the pedestal 11, the sliding seat 20 is slidably installed in the sliding slot through a pair of sliding rods 200, the two lifting seats 12 are slidably installed on the corresponding pedestal 11 and sliding seat 20 through a pair of stands 21, the annular clamp 13 is divided into upper and lower parts and connected and combined through the No. 1 bolt 22, the two pairs of pushing blocks 23 corresponding to the lifting seats 12 are slidably installed on the front and rear of the pedestal 11, the pushing blocks 23 have an isosceles triangular structure, the lifting seat 12 is provided with a wedge surface matched with the inclined surface of the pushing block 23, the annular clamp 13 is detachably installed with the concave-convex-shaped pressing block 24, the vertical section of the pressing block 24 is provided with an inclined surface matched with the pushing block 23, the No. 2 bolt 25 is threadedly installed on the pedestal 11 and rotatably connected with the sliding seat 20.

[0032] As Figure 1 , Figure 2 and Figure 4 shown, the guide mechanism 3 includes a slider 30, two opposite surfaces of the vertical section of the lifting seat 12 are slidingly installed with a slider 30, the upper end of the slider 30 is provided with a V-shaped groove, two front and rear symmetrical supporting rollers 31 are rotatably installed in the V-shaped groove through an axle seat, and the base 11 is provided with a driving part 4.

[0033] As Figure 1 , Figure 2 and Figure 4 shown, the two opposite surfaces of the vertical section of the lifting seat 12 are fixedly installed with a baffle 300 below the slider 30.

[0034] As Figure 3 , Figure 4 and Figure 5 shown, the end portions of the upper and lower parts of the annular clamp 13 are provided with an ear plate, a first bolt 22 is rotatably connected with the ear plate of the upper part of the annular clamp 13, and the lower end of the first bolt 22 is movably penetrated through the ear plate of the lower part of the annular clamp 13 and is threadedly connected with the corresponding lifting seat 12.

[0035] As Figures 1 to 5 shown, in specific work, the concrete base 10 is poured at the required position, and an anchor bolt (not shown in the figure) for fixing the base 11 is pre-buried during the pouring process, and a movable slot (not shown in the figure) is reserved. After the base 10 is solidified and formed, the base 11 is fixedly installed on the upper surface of the base 10 through the cooperation of the anchor bolt and the nut. Then the column 21 on the lifting seat 12 is slidingly penetrated through the base 11 and the sliding seat 20 and extends into the corresponding movable slot. Then the slider 30 is driven upward by the driving part 4, and the slider 30 drives the supporting roller 31 to move upward, so that the lowest point on the upper surface of the supporting 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 supporting roller 31 is adjusted through the driving part 4, so that the two pipes are located on the same axis.

[0036] After the adjustment is completed, the upper part of the annular clamp 13 is installed, the inner wall of the upper part of the annular clamp 13 is fitted with the pipe, then the first bolt 22 is rotated, since the upper part thereof is rotatably connected with the upper ear plate of the annular clamp 13 and the lower end thereof is threadedly connected with the lifting seat 12, the rotation of the first bolt 22 will drive the lower part of the annular clamp 13 to move upward, so that it is fitted with the lower surface of the pipe, and then the pressing block 24 is installed, and during the pressing process, the inclined surface thereof generates a wedge-shaped self-locking effect with the inclined surface of the pushing block 23, so as to reliably limit the downward movement of the lifting seat 12, and ensure the stability and anti-vibration performance of the locking.

[0037] Then the slider 30 is driven by the driving part 4 to move downward, and the slider 30 will be in contact with 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 with the base 11 and is rotationally connected with the sliding seat 20, the rotational movement of the second bolt 25 will be converted into the axial movement of the second bolt 25. When the second bolt 25 is rotated, the second bolt 25 is pushed to the left under the action of the threads of the base 11 and pushes the sliding seat 20 which is rotationally connected with the second bolt 25 to move synchronously to the left. The sliding seat 20 drives the corresponding pipeline to move to the left through the column 21, the lifting seat 12, the support and the annular clamp 13, so that the two pipeline ends are tightly butted and then welded.

[0038] Through the above-mentioned structure and cooperation, the deficiencies of the prior art are effectively overcome. The core advantage is that through the combination of the independent height adjustment of the supporting roller 31 and the wedge-shaped self-locking mechanism, the elevation error of the base 10 can be actively and accurately compensated, the uniform load of the multiple annular clamps 13 is ensured, and the stability and safety of the pipeline system are greatly improved. In addition, during the entire pipeline butt joint adjustment process, the pipeline is always provided with rolling support by the supporting roller 31, which avoids the movement difficulty and pipeline surface damage caused by traditional sliding friction, significantly improves the installation efficiency and protects the pipeline body.

[0039] As shown in Figure 1 , Figure 2 and Figure 4 , the driving part 4 comprises a fixed block 40 fixedly installed on the upper end of the base 11 and located between the two sliders 30. The opposite surfaces of the two sliders 30 are each provided with two inclined grooves 41, and the left and right ends of the fixed block 40 are each provided with a slot corresponding to the inclined grooves 41. A driving block 42 is slidably installed in the slot, and a guide column 43 slidably penetrating through the corresponding inclined groove 41 is fixedly installed on the driving block 42.

[0040] As shown in Figure 4 , the fixed block 40 is threadedly connected with two left-right symmetrical third bolts 44, and the third bolts 44 penetrate through the fixed block 40 and are rotationally connected with the corresponding two driving blocks 42.

[0041] As shown in Figure 4 , the inclined grooves 41 are inclined rearward from top to bottom.

[0042] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the adjusting mechanism 2 further comprises fixing assemblies, the base 11 is provided with fixing assemblies corresponding to the lifting seats 12, each fixing assembly is composed of two shaft plates symmetrically arranged in front of and behind the corresponding lifting seat 12, two limiting rods symmetrically arranged left and right of the corresponding lifting seat 12 are fixedly installed between the two shaft plates of the same group, and the pushing block 23 is slidingly installed on the corresponding limiting rod.

[0043] As shown in Figure 1 、 Figure 2 and Figure 6 , the horizontal section of the pressing block 24 is connected with the upper portion of the annular clamp 13 through the fourth bolt, and the vertical section of the pressing block 24 is slidingly matched with the ear plate.

[0044] As shown in Figures 1 to 6 , in specific work, first, the third bolt 44 is rotated through the external hydraulic wrench, since the third bolt 44 is threadedly connected with the fixed block 40 and is rotationally matched with the driving block 42, the rotational movement of the third bolt 44 will be converted into the axial movement of the third bolt 44, when the third bolt 44 is rotated, the third bolt 44 is pushed backward under the thread action of the fixed block 40, the backward movement of the third bolt 44 will drive the driving block 42 rotationally matched with the third bolt 44 to move backward synchronously, the backward movement of the driving block 42 will drive the sliding block 30 corresponding to the inclined groove 41 to move upward through the cooperation of the guide column 43 and the inclined groove 41, so that the lowest point of the upper surface of the supporting roller 31 is higher than the lowest point of the inner wall of the lower portion of the annular clamp 13, at this time, the two pipeline ends can be respectively placed on the corresponding supporting rollers 31, then the two third bolts 44 are respectively rotated to drive the corresponding driving blocks 42 to move and adjust the positions of the two pipelines through the cooperation of the guide column 43 and the inclined groove 41, so that the two pipelines are located on the same axis.

[0045] After the adjustment is completed, the annular clamp 13 is used to tightly hold and fix the pipelines, then the pressing block 24 is installed through the fourth bolt, so that the pressing block 24 moves downward and is pressed with the pushing block 23, to push the pushing block 23 to tightly adhere to the lifting seat 12, so as to fix the pipelines at the adjusted height.

[0046] After the second bolt 25 drives the sliding block 20 to move, to drive the corresponding pipeline to move and butt tightly with another pipeline, and in this moving process, the displacement is realized through the rolling friction between the pipeline and the supporting roller 31, which significantly reduces the moving resistance, not only guarantees the smoothness of the pipeline movement, but also effectively reduces the wear of the outer surface of the pipeline, thereby prolonging the service life of the pipeline, finally, the slider 30 is moved downward, so that the supporting roller 31 is completely lowered and is out of contact with the pipeline, then, the slider 30 is fully contacted with the baffle 300, at this time, the whole weight and load of the pipeline are finally borne by the annular clamp 13 which tightly holds it, and are transmitted to the base 10 through the support, the lifting seat 12, the pushing block 23 and the base 11, through this design, the displacement of the lifting seat 12 is completely limited from the vertical and horizontal directions, thereby realizing the high-quality and stable support of the pipeline, further guaranteeing the long-term safe use of the pipeline, finally, the exposed parts are treated to prevent rust, so as to facilitate subsequent maintenance and replacement, and prolong the service life of the parts, then, according to the above operation, the connection and support of the remaining pipelines are sequentially carried out from left to right.
