Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and in particular to a multi-stage adjustable pipe support for oil pipeline installation. Background Technology

[0002] An oil pipeline consists of oil pipes and their accessories, and is equipped with corresponding oil pump units according to the needs of the process flow. It is designed and installed into a complete pipeline system to complete the tasks of oil unloading and transportation.

[0003] Oil pipelines have become one of the main means of transporting oil. Currently, oil pipelines are generally installed using supports to ensure their safety during use. However, existing pipeline supports only provide simple fixing and support; workers still need to manually adjust the pipes at both ends to align them, and sometimes even flip the pipes to align with the bolt holes on the flanges. The entire pipeline installation process is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0018] The beneficial effects of this invention are:

[0019] (1) By setting up adjustment brackets and centering adjustment components, when the pipeline is installed, the air pump adjusts the air pressure of the piston chamber inside all the rotating drums through the air pipe, and uses the pressure difference to push the movable column radially through the connecting rod, so that all the adjustment wheels approach the pipeline synchronously until they contact and squeeze the pipeline, thereby achieving centering and clamping support for the pipeline, ensuring that the pipeline is always on the axis of the adjustment bracket during the installation process, so that the oil pipelines at both ends maintain a high degree of coaxiality during the installation process, so as to facilitate accurate docking and installation.

[0020] (2) By setting up adjusting rings and adjusting wheels, after the oil pipeline is centered and clamped, the adjusting motor drives all the rotating drums to rotate simultaneously through the adjusting rings. The rotating drums will drive the corresponding adjusting wheels to rotate synchronously until the wheel axis of the adjusting wheel is parallel to the axis of the pipeline. At this time, when the adjusting wheel rotates, it will drive the pipeline to rotate around the axis, thereby adjusting the position of the bolt holes of the flange at the end of the oil pipeline until they are all aligned, which facilitates the quick docking and installation of the flange at the end of the pipeline.

[0021] (3) After the oil pipelines at both ends are connected and installed, the adjusting motor drives all the rotating drums to rotate again through the adjusting ring until the direction of the wheel axle of the adjusting wheel is perpendicular to the direction of the pipeline axis. At this time, the rotation of the adjusting wheel will drive the pipeline to move along the axis direction. Combined with the linear sliding process of the supporting slide in the slide, the connected pipeline can be quickly and conveniently transported and transferred in a straight line, avoiding the time-consuming and laborious manual handling process, and greatly improving the efficiency of connecting and installing oil pipelines.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 and Figure 4 As shown, the present invention is a multi-stage adjustable pipe support for oil pipeline installation, including a fixed base 1 and an installation base 2. The upper end of the fixed base 1 is provided with a slide rail 11, and a support slide 12 is linearly slidably installed in the slide rail 11. A pair of floating supports 3 are fixedly installed on the upper end of the installation base 2, and an annular adjusting support 4 is fixedly installed between the floating supports 3. The axis of the adjusting support 4 coincides with the axis of the support slide 12. The oil pipeline passes through the adjusting support 4 and is supported on the floating supports 3 at both ends. Several centering adjusting components 5 are evenly arranged circumferentially on the inner wall of the adjusting support 4.

[0038] Specifically, before the oil pipelines are installed and connected, the oil pipelines at both ends are placed on the supporting slide 12 and the floating support 3, respectively. At this time, the adjusting support 4 does not support the pipelines, and the height of the oil pipelines at both ends is not aligned. After the oil pipelines are centered and clamped and supported by the centering adjusting component 5, the oil pipelines will be in the axial position of the adjusting support 4. Since the axis of the adjusting support 4 coincides with the axis of the supporting slide 12, the oil pipelines at both ends will automatically maintain coaxial alignment, ensuring the accuracy of the connection and installation. Then, the centering adjusting component 5 is used to gradually bring the oil pipelines at both ends closer together to facilitate the connection and installation of the sealing flanges at the pipeline ends.

[0039] like Figure 4 , Figure 7 and Figure 8 As shown, the centering adjustment assembly 5 includes a rotating cylinder 51, a movable column 52, and a fixed base 53. The rotating cylinder 51 is rotatably and sealed on the bottom of the fixed base 53. The top of the fixed base 53 is fixedly installed on the inner wall of the adjustment bracket 4. A sliding sleeve 511 extends from the bottom of the rotating cylinder 51. The movable column 52 is slidably installed in the sliding sleeve 511. A piston chamber 514 is provided inside the rotating cylinder 51. A connecting rod 522 is fixedly connected to the top of the movable column 52. The top of the connecting rod 522 extends into the piston chamber 514 and is fixedly connected to a piston plate 524. The piston plate 524 is slidably installed in the piston chamber 514. A rotating frame 54 is fixedly connected to the bottom of the movable column 52. An adjusting wheel 55 is rotatably installed in the rotating frame 54.

[0040] like Figure 5 , Figure 6 ,and Figure 7 As shown, an air pump 41 and an adjusting motor 42 are fixedly installed on both sides of the top of the adjusting bracket 4. An air pipe 43 and an adjusting ring 45 are respectively installed inside the adjusting bracket 4. The air pump 41 controls the adjusting wheel 55 to make radial displacement through the air pipe 43, and the adjusting motor 42 controls the adjusting wheel 55 to rotate around the axis of the movable column 52 through the adjusting ring 45.

[0041] Specifically, by setting up the adjusting bracket 4 and the centering adjusting component 5, during pipeline docking installation, the air pump 41 synchronously adjusts the air pressure of the piston chamber 514 inside all the rotating drums 51 through the air pipe 43, and uses the pressure difference to push the movable column 52 radially displaced through the connecting rod 522, so that all the adjusting wheels 55 synchronously approach the pipeline until they contact and squeeze the pipeline, thereby achieving centering and clamping support for the pipeline, ensuring that the pipeline is always in the axial position of the adjusting bracket 4 during the installation process, so that the oil pipelines at both ends maintain a high degree of coaxiality during the installation process, so as to facilitate accurate docking installation.

[0042] More specifically, such as Figure 11As shown, by setting the adjusting ring 45 and adjusting wheel 55, after the oil pipeline is centered and clamped, the adjusting motor 42 drives all the rotating drums 51 to rotate simultaneously through the adjusting ring 45. The rotating drums 51 will drive the corresponding adjusting wheels 55 to rotate synchronously (at this time, the adjusting wheels 55 still maintain contact and compression with the pipeline) until the wheel axis of the adjusting wheel 55 is parallel to the axis of the pipeline. At this time, when the adjusting wheel 55 rotates, it will drive the pipeline to rotate around the axis, thereby adjusting the position of the bolt holes of the end flange of the oil pipeline until they are all aligned, which facilitates the quick docking and installation of the end flange of the pipeline.

[0043] Among them, such as Figure 1 As shown, a storage box 21 is also fixedly installed on the upper end of the mounting base 2. The storage box 21 is used to hold various tools and locking bolts required for pipe flange connection installation, so as to facilitate workers to quickly carry out the installation.

[0044] More specifically, such as Figure 10 and Figure 12 As shown, after the oil pipelines at both ends are connected and installed, the adjusting motor 42 drives all the rotating drums 51 to rotate again through the adjusting ring 45 until the wheel axle direction of the adjusting wheel 55 is perpendicular to the pipeline axis direction. At this time, when the adjusting wheel 55 rotates, it will drive the pipeline to move along the axis direction. Combined with the linear sliding process of the supporting slide 12 in the slide 11, the connected pipeline can be quickly and conveniently transported and transferred in a straight line, avoiding the time-consuming and laborious manual handling process, and greatly improving the efficiency of oil pipeline connection and installation.

[0045] like Figure 5 and Figure 8 As shown, the vent pipe 43 is fixedly installed in the adjusting bracket 4. The air pump 41 is connected to the vent pipe 43 through the air inlet pipe 411. The vent pipe 43 is evenly connected with vent connectors 431 that correspond one-to-one with the fixed seat 53. The fixed seat 53 has an air inlet channel 531 that runs through it. The vent connectors 431 are connected to the air inlet channel 531. The air inlet channel 531 is connected to the piston chamber 514.

[0046] Specifically, the air pump 41 pumps air into the vent pipe 43 through the air inlet pipe 411. The vent pipe 43 then inflates the piston chamber 514 through the vent connector 431 and the air inlet channel 531. At this time, the pressure above the piston plate 524 gradually increases, which, through the connecting rod 522, pushes the movable column 52 and the adjusting wheel 55 to achieve radial clamping and convergence. When it is necessary to release the pipe, the air pump 41 begins to pump air. At this time, the pressure above the piston plate 524 gradually decreases, and finally, under the action of pressure, the movable column 52 and the adjusting wheel 55 are moved in the opposite direction through the connecting rod 522, thereby releasing the clamping and supporting effect on the pipe. Simultaneously, due to the radial displacement process of the adjusting wheel 55, it can adapt to the installation requirements of pipes of different diameters, making it highly adaptable.

[0047] like Figure 8 As shown, a sealed bearing 523 is provided at the connection between the connecting rod 522 and the rotating drum 51, and a rotating bearing 532 is provided at the connection between the rotating drum 51 and the fixed seat 53.

[0048] Specifically, the sealed bearing 523 and the rotating bearing 532 can effectively ensure the sealing performance of the piston chamber 514, preventing gas leakage and pressure changes. At the same time, the rotating bearing 532 allows the rotating cylinder 51 to rotate smoothly while maintaining a seal between the rotating cylinder 51 and the fixed seat 53, so as to facilitate the angle adjustment process.

[0049] like Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, rotating seats 44 are evenly fixed on the inner wall of the adjusting bracket 4. A rotating rod 441 is rotatably installed in each rotating seat 44. A synchronous gear 442 is sleeved on one end of the rotating rod 441, and a first bevel gear 443 is sleeved on the other end of the rotating rod 441. A second bevel gear 513 is fixed on the outer wall of the rotating cylinder 51. The first bevel gear 443 meshes with the corresponding second bevel gear 513.

[0050] like Figure 6 As shown, the adjusting ring 45 is rotatably installed inside the adjusting bracket 4. An outer ring toothed groove 451 is fixedly provided on the outer wall of the adjusting bracket 4. An adjusting gear 421 is fixedly connected to the output end of the adjusting motor 42. The adjusting gear 421 meshes with the outer ring toothed groove 451. An inner ring toothed groove 452 corresponding to the synchronous gear 442 is evenly fixedly provided on the inner wall of the adjusting bracket 4. The synchronous gear 442 meshes with the corresponding inner ring toothed groove 452.

[0051] Specifically, by setting the adjusting ring 45, the adjusting motor 42 is started, driving the adjusting gear 421 to rotate. The adjusting gear 421 drives the adjusting ring 45 to rotate within the adjusting bracket 4 through the outer ring tooth groove 451. During this process, the inner ring tooth groove 452 on the adjusting ring 45 meshes with the corresponding synchronous gear 442, thereby driving all rotating rods 441 to rotate simultaneously. The rotating rods 441 will drive the corresponding rotating drum 51 to rotate synchronously through the bevel gear transmission pair, thereby enabling all adjusting wheels 55 to rotate synchronously, and thus enabling the adjusting wheel 55 shaft to flexibly switch between being parallel or perpendicular to the pipeline axis.

[0052] like Figure 7 and Figure 8 As shown, sliding grooves 512 are provided through both sides of the sliding sleeve 511, and sliding pins 521 are fixedly provided on both sides of the movable column 52. The sliding pins 521 are slidably installed in the corresponding sliding grooves 512.

[0053] Specifically, the sliding groove 512 utilizes the sliding pin 521 to apply rotational constraints to the movable column 52, preventing unnecessary rotation of the movable column 52 relative to the rotating drum 51. When the rotating drum 51 rotates, the sliding pin 521 drives the movable column 52 to rotate synchronously, while the movable column 52 can undergo axial displacement within the sliding sleeve 511. This ensures that the radial movement and rotational adjustment processes of the adjusting wheel 55 are independent and do not interfere with each other.

[0054] like Figure 5 and Figure 6 As shown, a limiting outer groove 402 is provided on the outer wall of the adjusting bracket 4, and an outer ring toothed groove 451 is adapted to slide and install in the limiting outer groove 402. A limiting inner groove 401 is evenly provided on the inner wall of the adjusting bracket 4, and an inner ring toothed groove 452 is adapted to slide and install in the limiting inner groove 401.

[0055] Specifically, in order to constrain and limit the rotation angle of the adjusting ring 45, a limiting outer groove 402 and a limiting inner groove 401 are set. When the adjusting ring 45 rotates, the outer ring tooth groove 451 rotates in the limiting outer groove 402, and the inner ring tooth groove 452 rotates in the corresponding limiting inner groove 401. When the outer ring tooth groove 451 and the inner ring tooth groove 452 slide to the limit position, the adjusting wheel 55 has rotated exactly 90°. This allows for accurate control of the rotation angle of the adjusting wheel 55 and avoids deviation in the rotation angle of the adjusting wheel 55 due to excessive rotation of the adjusting ring 45.

[0056] like Figure 8 As shown, a drive motor 56 is fixedly installed on the side wall of the rotating frame 54. The output end of the drive motor 56 is connected to the adjusting wheel 55. A friction rubber ring 551 is fixedly installed on the outer circumferential wall of the adjusting wheel 55.

[0057] Specifically, when the adjusting wheel 55 comes into contact with and presses against the outer wall of the oil pipeline, the friction rubber ring 551 can effectively increase the friction between the two. When the drive motor 56 drives the adjusting wheel 55 to rotate, it can effectively prevent the adjusting wheel 55 from slipping on the pipeline surface, so that the adjusting wheel 55 can drive the oil pipeline to rotate axially or move linearly.

[0058] like Figure 3 As shown, a support block 31 is fixedly installed at the top of the floating bracket 3, and several balls 311 are rolled on the inner wall of the support block 31. Floating columns 32 are fixedly installed at both ends of the bottom of the floating bracket 3. A base plate 33 is installed below the floating bracket 3. The base plate 33 is fixedly installed on the mounting base 2. A sleeve 34 is fixedly installed at the upper end of the base plate 33. The floating columns 32 are slidably installed in the sleeve 34. A support spring 321 is fixedly installed between the bottom end of the floating column 32 and the bottom of the sleeve 34.

[0059] Specifically, before the oil pipeline is centered and clamped, it is placed on the support blocks 31 at both ends. The support blocks 31, under pressure, push the floating column 32 downwards within the sleeve 34, compressing the support spring 321. When the oil pipeline is centered and clamped, the support blocks 31 automatically float upwards under the elastic force of the support spring 321, providing auxiliary support for the oil pipeline. Simultaneously, the ball bearings 311 on the inner wall of the support blocks 31 contact and compress with the pipeline surface, allowing the oil pipeline to smoothly rotate or move linearly using the free rolling of the ball bearings 311.

[0060] like Figure 2 and Figure 12 As shown, a slider 121 is fixedly installed at the bottom of the supporting slide 12 along the axial direction. The slider 121 is linearly slidably installed in the groove in the slide rail 11. A positioning buckle 122 is rotatably installed on one side of the top of the supporting slide 12. A rubber pad 123 is fixedly installed on the inner wall of the positioning buckle 122. A baffle 124 is provided extending outward from the end of the supporting slide 12 away from the adjusting bracket 4. A connecting slide plate 125 is fixedly installed at the bottom of the baffle 124. A guide rod 111 is fixedly installed at one end of the slide rail 11. The connecting slide plate 125 is slidably installed on the guide rod 111. A push-pull cylinder 13 is fixedly installed at the upper end of the fixed base 1. The output end of the push-pull cylinder 13 is fixedly connected to the connecting slide plate 125.

[0061] Specifically, when one end of the oil pipeline is placed on the support slide 12, the positioning buckle 122 is flipped to snap onto the upper end of the oil pipeline and secured with locking bolts. This effectively positions the oil pipeline and prevents it from shifting during installation. The rubber pad 123 increases the contact area and friction with the pipeline surface, thereby effectively improving positioning stability. After the pipelines at both ends are connected and installed, the push-pull cylinder 13 pushes the connecting slide 125 forward, causing the support slide 12 to gradually slide out of the slide rail 11. During this process, the connecting slide 125 remains on the guide rod 111 to ensure balance and stability during the movement. When the oil pipeline is transported out with the support slide 12, the positioning buckle 122 can be opened, and the installed oil pipeline can be removed from the support slide 12.

[0062] The working principle of this invention is as follows: Figures 1-12As shown, during use, before the oil pipelines are installed and connected, the oil pipelines at both ends are placed on the supporting slide 12 and the floating support 3 respectively. At this time, the adjusting support 4 does not support the pipelines, and the height positions of the oil pipelines at both ends are not aligned. During the pipeline connection and installation, the air pump 41 synchronously adjusts the air pressure of the piston chambers 514 inside all the rotating cylinders 51 through the air pipe 43, and uses the pressure difference to push the movable column 52 radially displaced through the connecting rod 522, so that all the adjusting wheels 55 synchronously approach the pipeline until they contact and squeeze the pipeline, thereby achieving the centering and clamping support of the pipeline. This ensures that the pipeline is always in the axial position of the adjusting support 4 during the installation process. At the same time, since the axis of the adjusting support 4 coincides with the axis of the supporting slide 12, the oil pipelines at both ends will automatically maintain coaxial alignment, ensuring the accuracy of the connection and installation. After the oil pipeline is aligned and clamped, the adjusting motor 42 drives all the rotating drums 51 to rotate simultaneously via the adjusting ring 45. Each drum 51 drives its corresponding adjusting wheel 55 to rotate synchronously (while the adjusting wheel 55 remains in contact with the pipeline). This continues until the axle of the adjusting wheel 55 is parallel to the pipeline axis. At this point, the rotation of the adjusting wheel 55 causes the pipeline to rotate around its axis, thus adjusting the bolt hole positions of the pipeline end flanges until they are all aligned. After the bolt holes are aligned, the adjusting motor 42 drives all the rotating drums 51 to rotate again via the adjusting ring 45 until the axle of the adjusting wheel 55 is perpendicular to the pipeline axis. At this point, the rotation of the adjusting wheel 55 causes the pipeline to shift along its axis until the sealing flanges at both ends are aligned. Finally, the locking bolts are used to quickly and securely install the pipeline flanges. After the pipeline connection and installation are completed, the adjusting wheel 55 drives the oil pipeline to continue to be transported forward. At the same time, the push-pull cylinder 13 pushes the connecting slide plate 125 forward, so that the supporting slide 12 gradually slides out from the slide rail 11. When the oil pipeline is transported out with the supporting slide 12, the positioning buckle plate 122 can be opened and the installed oil pipeline can be unloaded from the supporting slide 12.

[0063] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
