Description

Technical Field

[0001] This invention relates to the field of pipeline equipment technology, and in particular to a device for fixing and installing elbows in long-distance pipelines and its usage method. Background Technology

[0002] Long-distance pipelines are long-distance pipeline systems used to transport media such as oil and natural gas. As a key infrastructure for modern energy transmission, they are typically characterized by large pipe diameters, high transmission pressures, long transmission distances, and large transmission capacities. Long-distance pipelines are mostly made of steel pipes, with pipe sections connected by welding and other methods, and laid underground or above ground. Their pipe structure must have good sealing performance and corrosion resistance to ensure the safety and stability of the transmission process.

[0003] In long-distance pipeline systems, fixed installation equipment for elbows is a crucial component for ensuring the structural integrity of the pipeline. Due to the high-pressure characteristics of the transported medium and the hydrodynamic effects generated when the fluid flows through elbows, elbows often experience complex axial thrust, centrifugal force, and bending moment. Specifically, when the fluid changes direction at an elbow, the resulting impact force can be several times that of the straight pipe section. This stress state easily leads to stress concentration at the elbow. By installing fixed installation equipment at elbows, displacement at the elbows can be constrained, thereby alleviating stress concentration to some extent and maintaining the geometric stability of the pipeline.

[0004] However, when long-distance pipelines are laid in geologically unstable areas such as landslide zones, geological changes can easily cause the failure of the pipeline's underlying supports, leading to potential displacement of the pipeline under its own weight and external loads. Because existing fixed installation equipment at elbows obstructs certain areas of the pipeline, it is difficult for inspectors to directly visually observe the welds in these obstructed areas or conduct contact inspections using tools after displacement occurs. This limitation makes it difficult to detect and identify defects such as cracks, porosity, and slag inclusions in the welds in a timely manner, thus increasing the safety risks during subsequent pipeline operation.

[0005] Therefore, there is an urgent need for a device for fixing and installing elbows in long-distance pipelines and its usage method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a device for fixing and installing elbows in long-distance pipelines and its usage method, so as to solve the technical problems existing in the prior art and achieve the technical effects.

[0007] Based on the above concept, the technical solution adopted by this invention is as follows: On the one hand, a long-distance pipeline elbow fixing and installation device is provided, including a first mounting plate and a second mounting plate, wherein the first mounting plate and the second mounting plate are detachably connected and are respectively connected to both ends of the pipeline bend; The first mounting plate is provided with a clamping mechanism, which includes a support base, a cover plate assembly and an elastic limiting assembly. The cover plate assembly and the support base are respectively located on both sides of the pipe body. The elastic limiting assembly is disposed on the support base and has a tendency to bring the cover plate assembly closer to the support base so that the cover plate assembly can press the pipe body against the support base. The second mounting plate is provided with a shock-absorbing mechanism, which includes an open pipe sleeve, a connecting seat, and an elastic component. The open pipe sleeve is fitted onto the pipe body, one end of the connecting seat is connected to the open pipe sleeve, and the other end is provided with the elastic component so that the connecting seat can be elastically placed on the second mounting plate.

[0008] Preferably, the support base includes a horizontal plate and a vertical plate connected in a T-shape. The horizontal plate is arranged parallel to the first mounting plate. Both ends of the horizontal plate are provided with connecting holes. The elastic limiting component includes a rubber strip and a threaded rod. Both ends of the rubber strip are connected to the threaded rod. Both threaded rods can pass through the connecting holes on the horizontal plate and be threadedly connected to a nut.

[0009] Preferably, both ends of the rubber strip are provided with spherical connectors, and a grooved rod head is rotatably connected to the outside of the connector. The grooved rod head is threadedly connected to the end of the threaded rod away from the nut.

[0010] Preferably, the cover plate assembly includes a first cover plate and a second cover plate, the second cover plate being connected to the end of the first cover plate near the shock absorption mechanism, and multiple elastic limiting components are provided, with both the first cover plate and the second cover plate being pressed against the pipe body by the elastic limiting components.

[0011] Preferably, the second cover plate has a slot at one end near the shock absorption mechanism, and the open tube sleeve has a locking plate that mates with the slot, so that the slot and the locking plate can engage.

[0012] Preferably, the side of the connecting seat facing the second mounting plate is provided with a groove; the elastic component includes an elastic element and a connecting tube, one end of the elastic element is connected to the bottom of the groove, the other end is connected to the connecting tube, and the end of the connecting tube away from the elastic element extends out of the groove.

[0013] Preferably, a connecting block is further provided in the groove of the connecting seat. The connecting block includes a cylindrical guide portion and retaining rings protruding from both ends of the guide portion. A retaining ring is provided at the end of the connecting tube away from the second mounting plate. The retaining ring is sleeved on the guide portion. The elastic element is sleeved on the guide portion and one end is connected to the end of the retaining ring away from the second mounting plate, and the other end is connected to the retaining ring away from the second mounting plate.

[0014] Preferably, the second mounting plate is provided with a plurality of guide posts, and the connecting seat is provided with a plurality of positioning holes that mate with the plurality of guide posts one by one.

[0015] Preferably, the clamping mechanism is also provided at the end of the second mounting plate away from the first mounting plate.

[0016] On the other hand, a method for using a long-distance pipeline elbow fixing and installation device is provided, the method comprising the following steps: S1. After the open sleeve is fitted onto the pipe body, place the end of the elastic component away from the connector on the second mounting plate. S2. Connect the first mounting plate to the second mounting plate, install the elastic limiting component on the support base, and then place the cover plate component between the elastic limiting component and the pipe body. S3. If the weld of the pipe body is covered by the cover plate assembly, pull the elastic limiting assembly and move the cover plate assembly to expose the weld of the pipe body.

[0017] The beneficial effects of this invention are: The long-distance pipeline elbow fixing and installation equipment provided by this invention forms an integral rigid frame through a detachable connection between a first mounting plate and a second mounting plate. The first and second mounting plates are respectively connected to both ends of the pipeline bend, thereby achieving integrated fixing and protection of the long-distance pipeline elbow area. The clamping mechanism on the first mounting plate continuously applies a tensile force towards the support seat to the cover plate assembly through an elastic limiting component, ensuring that the cover plate assembly is always tightly fitted to the outer wall of the pipeline body and presses the pipeline body against the support seat. Even if the pipeline experiences slight thermal expansion and contraction due to temperature changes, the elastic limiting component can automatically compensate for gaps and maintain stable clamping force. The connecting seat in the shock absorption mechanism on the second mounting plate is flexibly connected to the second mounting plate through an elastic component, forming an elastic support system. When the pipeline vibrates, the elastic component undergoes elastic deformation, converting the vibration kinetic energy into elastic potential energy and gradually dissipating it, thereby reducing the vibration amplitude and protecting the elbow welded joint from damage. The entire equipment, through a combination of rigidity and flexibility, ensures precise fixing of the pipeline elbow position and provides buffering to reduce the risk of displacement damage when the pipeline body is subjected to external impact displacement. Moreover, operators can quickly release the pressure of the cover plate assembly by stretching the elastic limiting component, thereby separating the cover plate from the pipe body and exposing sufficient operating space for inspecting the welds on the pipe body. Inspectors can directly observe and place inspection tools, significantly improving the efficiency of weld inspection after pipe displacement.

[0018] The method of using the long-distance pipeline elbow fixing and installation equipment provided by the present invention can ensure the accuracy of the weld inspection results after the pipeline body is displaced. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0026] like Figures 1 to 8 As shown, this embodiment provides a long-distance pipeline elbow fixing and installation device, including a first mounting plate 1 and a second mounting plate 2. The first mounting plate 1 and the second mounting plate 2 are detachably connected and respectively connected to both ends of the pipeline bend. A clamping mechanism 11 is provided on the first mounting plate 1. The clamping mechanism 11 includes a support base 111, a cover plate assembly 112, and an elastic limiting assembly 113. The cover plate assembly 112 and the support base 111 are respectively located on both sides of the pipeline body 100. The elastic limiting assembly 113 is disposed on the support base 111. The elastic limiting assembly 113 has a tendency to bring the cover plate assembly 112 closer to the support base 111 so that the cover plate assembly 112 can press the pipeline body 100 against the support base 111. The second mounting plate 2 is provided with a shock absorption mechanism 21. The shock absorption mechanism 21 includes an open pipe sleeve 211, a connecting seat 212 and an elastic component 213. The open pipe sleeve 211 is fitted onto the pipe body 100. One end of the connecting seat 212 is connected to the open pipe sleeve 211, and the other end is provided with an elastic component 213 so that the connecting seat 212 is elastically placed on the second mounting plate 2.

[0027] Specifically, such as Figure 2As shown, in this embodiment, the first mounting plate 1 and the second mounting plate 2 are snapped together. The first mounting plate 1 has a snap-fit ​​groove, and the second mounting plate 2 has a snap-fit ​​component that mates with the snap-fit ​​groove. The snap-fit ​​component on the second mounting plate 2 can snap into the snap-fit ​​groove on the first mounting plate 1, thereby fixing the first mounting plate 1 and the second mounting plate 2. A curved groove 1111 is provided on the side of the support base 111 away from the first mounting plate 1. The elastic limiting component 113 presses the cover plate body tightly against the pipe body 100 and compresses the pipe body 100 within the curved groove 1111 of the support base 111. More specifically, the snap-fit ​​groove and the snap-fit ​​component are respectively provided at the ends of the first mounting plate 1 and the second mounting plate 2. The first mounting plate 1 is arranged vertically, and the second mounting plate 2 is vertically connected to its lower end in the horizontal direction.

[0028] It is understood that the long-distance pipeline elbow fixing and installation equipment provided in this embodiment forms an integral rigid frame through the detachable connection between the first mounting plate 1 and the second mounting plate 2. The first mounting plate 1 and the second mounting plate 2 are respectively connected to both ends of the pipeline bend, thereby achieving integrated fixing and protection of the long-distance pipeline elbow area. The clamping mechanism 11 provided on the first mounting plate 1 continuously applies a pulling force towards the support seat 111 to the cover plate assembly 112 through the elastic limiting component 113, so that the cover plate assembly 112 is always tightly attached to the outer wall of the pipeline body 100 and presses the pipeline body 100 against the support seat 111. Even if the pipeline undergoes slight thermal expansion and contraction due to temperature changes, the elastic limiting component 113 can automatically compensate for the gap and maintain a stable clamping force. The connecting seat 212 in the shock absorption mechanism 21 on the second mounting plate 2 is flexibly connected to the second mounting plate 2 through the elastic component 213 to form an elastic support system. When the pipeline vibrates, the elastic component 213 undergoes elastic deformation, converting the vibration kinetic energy into elastic potential energy and gradually dissipating it, thereby reducing the vibration amplitude and protecting the welded joint of the elbow from damage. The entire device, through a combination of rigidity and flexibility, ensures precise fixation of the pipeline elbow position while providing buffering to reduce the risk of displacement damage when the pipeline body 100 is subjected to external impact and displacement. Furthermore, operators can quickly release the pressure on the cover plate assembly 112 by stretching the elastic limiting component 113, thereby separating the cover plate from the pipeline body 100 and exposing sufficient operating space for weld inspection on the pipeline body 100. Inspectors can directly observe and place inspection tools, significantly improving the efficiency of weld inspection after pipeline displacement.

[0029] Furthermore, in some embodiments, the support base 111 includes a T-shaped horizontal plate and a vertical plate. The horizontal plate is arranged parallel to the first mounting plate 1. Both ends of the horizontal plate have connecting holes 1112. The elastic limiting component 113 includes a rubber strip 1131 and threaded rods 1132. Both ends of the rubber strip 1131 are connected to threaded rods 1132, and both threaded rods 1132 can pass through the connecting holes 1112 on the horizontal plate and be threadedly connected to a nut 1133. Figure 3 As shown, in this embodiment, both the horizontal and vertical plates extend vertically, meaning the projection of the support base 111 on the second mounting plate 2 is T-shaped. Connecting holes 1112 are located at both ends of the horizontal plate, i.e., the rubber strip 1131 and the nut 1133 are located on opposite sides of the horizontal plate, allowing the rubber strip 1131 to press the pipe body 100 into the curved groove 1111 of the support base 111 via the cover plate assembly 112. It is understood that configuring the support base 111 as a T-shaped connection between the horizontal and vertical plates allows the horizontal plate to fit precisely against the pipe body 100, providing a stable support surface; furthermore, the horizontal plate remains parallel to the first mounting plate 1, facilitating flat mounting on the surface of the first mounting plate 1 and providing a flat reference surface for the installation of the elastic limiting assembly 113. Connecting holes 1112 are provided at both ends of the horizontal plate. The threaded rod 1132 passes through the connecting holes 1112 and engages with the nut 1133. Due to the arrangement of the vertical plate, the threaded rod 1132 has sufficient room to move. By tightening the nut 1133, the relative distance between the rubber strip 1131 and the horizontal plate can be adjusted, thereby changing the degree of pressure of the cover plate assembly 112 on the pipe body 100. The rubber strip 1131 itself has elastic deformation capability. When its two ends are pulled towards the horizontal plate by the threaded rod 1132, the middle area of ​​the rubber strip 1131 adheres to the surface of the cover plate assembly 112 and generates elastic tension, which can ensure uniform pressure on the contact surface with the cover plate assembly 112.

[0030] More specifically, a pull ring 11311 is provided on the rubber strip 1131, and the pull ring 11311 is rotatably connected to the rubber strip 1131. When the operator needs to stretch the rubber strip 1131, he / she pulls the rubber strip 1131 through the pull ring 11311.

[0031] Furthermore, such as Figure 4 and Figure 5 As shown, in some embodiments, both ends of the rubber strip 1131 are provided with spherical connectors 1134, and the outer side of the connectors 1134 is rotatably connected to a grooved rod head 1135, which is threadedly connected to the end of the threaded rod 1132 away from the nut 1133.

[0032] Understandably, the placement of spherical connectors 1134 at both ends of the rubber strip 1131, forming a ball-joint rotational connection with the grooved rod head 1135, serves two purposes. First, it eliminates the torsional stress that may be generated during the tightening of the threaded rod 1132. When the nut 1133 is screwed onto the threaded rod 1132, if the threaded rod 1132 is rigidly fixed to the rubber strip 1131, the rotational torque will be transmitted to the rubber strip 1131, causing it to twist or generate additional shear stress, affecting its service life and clamping effect. The ball-joint structure allows the threaded rod 1132 to rotate freely relative to the rubber strip 1131, ensuring that the tightening of the nut 1133 only generates tension along the axial direction of the threaded rod 1132, keeping the rubber strip 1131 in a naturally extended state, resulting in a more even and reasonable force distribution. Second, the spherical surface of the spherical connector 1134, in conjunction with the inner ball socket of the grooved rod head 1135, can compensate within a certain angular range, reducing the accuracy requirements for installation alignment and improving the convenience of on-site construction.

[0033] Furthermore, in some embodiments, the cover plate assembly 112 includes a first cover plate 1121 and a second cover plate 1122. The second cover plate 1122 is connected to the end of the first cover plate 1121 near the shock absorption mechanism 21. Multiple elastic limiting components 113 are provided. The first cover plate 1121 and the second cover plate 1122 are both pressed onto the pipe body 100 by the elastic limiting components 113.

[0034] Specifically, such as Figure 4 As shown, the vertical dimension of the first cover plate 1121 is smaller than that of the second cover plate 1122. The first cover plate 1121 corresponds to the end of the support base 111 away from the second mounting plate 2, and the second cover plate 1122 is connected to the shock absorption mechanism 21. It can be understood that this arrangement can withstand the clamping force applied by the elastic limiting component 113 as a whole. The bottom end of the first cover plate 1121 is provided with an arc-shaped notch and a connecting groove located in the middle of the arc-shaped notch. The second cover plate 1122 is provided with a connecting protrusion corresponding to the connecting groove, and the connecting protrusion is pivotally connected to the connecting groove. Through this segmented cover plate design, when it is necessary to inspect the welds on the pipe body 100, it is only necessary to stretch the corresponding rubber strip 1131 and rotate to open the cover plate at the corresponding position, which can ensure that the position of the pipe body 100 remains fixed during inspection.

[0035] More specifically, a first hook 11211 is provided on the first cover plate 1121, a second hook 11221 is provided on the second cover plate 1122, and a third hook 2111 is provided on the open sleeve. The first hook 11211 is used to position the rubber strip 1131 on the first cover plate 1121. When the first cover plate 1121 needs to be opened, the rubber strip 1131 on the first cover plate 1121 is hooked on the second hook 11221; when the second cover plate 1122 needs to be opened, the rubber strip 1131 on the second cover plate 1122 is hooked on the third hook 2111. Due to the cooperation of the grooved rod head 1135 and the connector 1134, both ends of the rubber strip 1131 can rotate at a certain angle, making it easier to hook the rubber strip 1131 on different hooks.

[0036] Furthermore, in some embodiments, the second cover plate 1122 is provided with a slot 11222 at one end near the shock absorption mechanism 21, and the open tube sleeve 211 is provided with a locking plate 2112 that cooperates with the slot 11222, and the slot 11222 and the locking plate 2112 can be engaged.

[0037] Understandably, a slot 11222 is provided at the end of the second cover plate 1122, and a corresponding clamping plate 2112 is provided on the open pipe sleeve 211 to form a clamping structure. This clamping structure can transfer part of the clamping force in the area of ​​the first mounting plate 1 to the side of the shock absorption mechanism 21, while preventing the open pipe sleeve 211 from axially moving or rotating due to pipe vibration. Once the clamping is completed, the entire device forms a closed force transmission path at both ends of the bend, and the fixing and shock absorption functions on both sides of the pipe bend can work together, further enhancing the stability and vibration resistance of the overall structure.

[0038] In some embodiments, the side of the connector 212 facing the second mounting plate 2 is provided with a groove; the elastic component 213 includes an elastic element 2131 and a connecting tube 2132, one end of the elastic element 2131 is connected to the bottom of the groove, the other end is connected to the connecting tube 2132, and the end of the connecting tube 2132 away from the elastic element 2131 extends out of the groove.

[0039] Understandably, by creating a groove on the bottom surface of the connecting seat 212 and arranging the elastic component 213 within the groove, the elastic connection between the connecting seat 212 and the second mounting plate 2 can be concealed, resulting in a more compact overall structure. Simultaneously, the sidewall of the groove guides and protects the elastic component 2131, preventing lateral bending during use. One end of the elastic component 2131 is fixed to the bottom of the groove, and the other end is connected to the connecting pipe 2132, which extends out of the groove and is directly supported on the second mounting plate 2. When pipeline vibration is transmitted to the connecting seat 212 through the open sleeve 211, the relative movement between the groove and the connecting pipe 2132 causes the elastic component 2131 to be compressed or stretched, thereby absorbing vibration energy. The elastic component 2131 can be in various forms, such as a metal helical spring, a rubber column, or a disc spring; the specific selection can be determined based on the pipeline vibration frequency and amplitude. The connecting pipe 2132, as a transition piece between the elastic element 2131 and the second mounting plate 2, can be designed with different length specifications to adapt to different installation height requirements and improve the on-site adaptability of the equipment.

[0040] A connecting block 2133 is also provided in the groove of the connecting seat 212. The connecting block 2133 includes a cylindrical guide portion and retaining rings protruding from both ends of the guide portion. That is, the projection of the connecting block 2133 on the first mounting plate 1 is "I" shaped. A retaining ring is provided at the end of the connecting tube 2132 away from the second mounting plate 2. The retaining ring is sleeved on the guide portion. The elastic element 2131 is sleeved on the guide portion and one end is connected to the end of the retaining ring away from the second mounting plate 2, and the other end is connected to the retaining ring away from the second mounting plate 2.

[0041] Understandably, by adding a connecting block 2133 within the groove, and through the interaction of the guide portion, retaining ring, retaining ring, and elastic element 2131, a compact and stable elastic guiding assembly is formed. The guide portion of the connecting block 2133 is cylindrical and fits with the inner hole of the retaining ring with a clearance, providing precise guidance for the axial movement of the connecting tube 2132 and preventing the elastic element 2131 from skewing or jamming during compression. The retaining ring protrudes from both ends of the guide portion; the retaining ring on the side away from the second mounting plate 2 is used to limit one end of the elastic element 2131, while the retaining ring on the side closer to the second mounting plate 2 limits the maximum displacement stroke of the retaining ring. The retaining ring is fixed to the end of the connecting tube 2132, sleeved on the guide portion, and can slide along the guide portion. The elastic element 2131 is sleeved on the outside of the guide portion, with one end abutting against the retaining ring and the other end abutting against the upper retaining ring. When the connecting seat 212 moves downward due to vibration, the connecting tube 2132 remains in the same position relative to the second mounting plate 2, the retaining ring moves upward along the guide, and the elastic element 2131 is compressed, thus providing a buffering effect. When the vibration direction is reversed, the elastic element 2131 rebounds and pushes the retaining ring back to its original position. This structural design ensures that the elastic element 2131 always works under the constraint of the guide, with a straight movement trajectory and stable stress state, effectively extending the service life of the elastic element 2131 and ensuring the long-term reliability of the shock absorption effect.

[0042] Furthermore, such as Figure 2 and Figure 6 As shown, the second mounting plate 2 is provided with a plurality of guide posts 22, and the connecting seat 212 is provided with a plurality of positioning holes 2121 that cooperate with the plurality of guide posts 22 one by one.

[0043] Understandably, the guide post 22 is vertically fixed to the second mounting plate 2, and the corresponding positioning hole 2121 on the connecting seat 212 and the guide post 22 are fitted with a clearance fit. This ensures that the connecting seat 212 can slide freely along the axis of the guide post 22 to achieve vibration damping, while also preventing the connecting seat 212 from undergoing lateral displacement or torsion due to the lateral force of the pipeline. The number, diameter, and arrangement of the guide posts 22 can be adjusted according to the pipeline specifications and stress analysis. They are usually symmetrically arranged on both sides of the connecting seat 212 to ensure balanced stress.

[0044] To better secure the pipe body 100, such as Figure 1 and Figure 2 As shown, in this embodiment, the end of the second mounting plate 2 away from the first mounting plate 1 is also provided with a clamping mechanism 11.

[0045] Understandably, a clamping mechanism 11 is added to the other end of the second mounting plate 2. This arrangement ensures that the straight pipe sections on both sides of the elbow are firmly constrained. The damping mechanism 21 is located between the two clamping mechanisms 11, forming a "fixed-damping-fixed" mechanical layout. When the pipe elbow vibrates due to internal pressure fluctuations or fluid impact, the clamping mechanisms 11 on both sides provide reliable boundary support conditions, while the damping mechanism 21 in the middle absorbs and attenuates vibration energy, preventing vibration from propagating to distant pipes and effectively protecting the elbow and its upstream and downstream pipe welds, flange connections, and other weak points. In addition, the combined action of the clamping mechanisms 11 on both sides can share the axial thrust of the pipe, preventing pipe slippage or elbow angle deformation caused by insufficient fixation on one side, which is especially suitable for high-pressure, high-flow-rate long-distance pipeline systems.

[0046] This embodiment also provides a method for using a long-distance pipeline elbow fixing and installation device, the method for using the above-mentioned long-distance pipeline elbow fixing and installation device includes the following steps: S1. After the open sleeve is fitted onto the pipe body 100, place the end of the elastic component 213 away from the connecting seat 212 on the second mounting plate 2.

[0047] S2. Connect the first mounting plate 1 and the second mounting plate 2, install the elastic limiting component 113 on the support base 111, and then place the cover plate component 112 between the elastic limiting component 113 and the pipe body 100.

[0048] S3. If the weld of the pipe body 100 is covered by the cover plate assembly 112, pull the elastic limiting assembly 113 and move the cover plate assembly 112 to expose the weld of the pipe body 100.

[0049] Specifically, first, the connecting seat 212 is moved upward to separate the open sleeve from the connecting block 2133. Then, the guide post 22 is aligned with the positioning hole 2121 one by one, and the connecting seat 212 is reinstalled on the connecting block 2133. Next, the open sleeve is placed on the pipe body 100, and the second cover plate 1122 is moved so that the slot 11222 engages with the plate 2112. Then, the elastic limiting component 113 is installed on the support seat 111, allowing the elastic limiting component 113 to drive the cover plate assembly 112 to press against the pipe body 100. When it is necessary to inspect the weld of the pipe body 100, the gap between the cover plate assembly 112 and the support seat 111 is observed. If the weld is obscured, the rubber strip 1131 of the corresponding cover plate is pulled, and the corresponding cover plate is rotated to expose the pipe body 100 for inspection by the operator.

[0050] When the long-distance pipeline elbow is not needed for installation, first remove the elastic limiting component 113 and the cover plate component 112, then lift the pipeline body 100 upwards to separate the connecting seat 212 from the connecting block 2133, and then remove the open pipe sleeve 211 to complete the disassembly.

[0051] The method of using the long-distance pipeline elbow fixing and installation equipment provided in this embodiment can ensure the accuracy of the weld inspection results after the pipeline body 100 is displaced, and significantly improve the weld inspection efficiency after pipeline displacement.
