Description

Technical Field

[0001] This invention relates to the field of compensator technology, specifically to a compensator with adjustment function. Background Technology

[0002] In various pipeline transportation systems, pipelines inevitably undergo thermal expansion and contraction due to temperature changes. Existing compensators may not be able to fully meet the compensation requirements, resulting in pipelines still bearing significant stress.

[0003] Patent CN219866868U discloses a compensator with an adjustable function, comprising a pipe body, a hinged connection, and an adjustable telescopic connection. Connecting end pipes are connected to both ends of the pipe body. The hinged connection is connected to both ends of the pipe body. This device, through the cooperation of a telescopic fixed end block, a telescopic inner pipe, a sealing rubber ring, a first nut fixing block, a threaded connection block, a threaded rod, a hexagonal head, a threaded rod, a second nut fixing block, and the connecting end pipe, allows for flexible adjustment of the compensator's length according to actual working conditions. This enables the compensator to maintain optimal working condition under various complex working conditions. The adjustable telescopic connection can adjust according to the actual displacement of the pipeline. Adjustments are made to ensure a more reasonable stress distribution during operation of the compensator, reducing stress concentration or excessive stretching caused by excessive or insufficient compensation, thereby extending the compensator's service life. Although the device can be adjusted by adjusting the telescopic connection to make the stress distribution more reasonable during equipment operation and improve the stability of equipment transportation, the device will shake during transportation. This can easily cause the equipment compensation to lack buffering, resulting in stress concentration at the shaking point, which can damage the equipment, reduce its service life, and make it difficult to guarantee the equipment's compensation reset. Therefore, a compensator with adjustment function is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a compensator with adjustment function in view of the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a compensator with an adjustment function, comprising a compensating tube, an extension adjustment sleeve installed on the inner wall of the compensating tube, a connecting plate fixedly connected to the circumferential surface of the compensating tube, a bolt slidably connected to the inner wall of the connecting plate, a nut threadedly connected to the circumferential surface of the bolt, oil pipes provided on the front and rear sides of the compensating tube, positioning and buffering mechanisms provided on both sides of the connecting plate, and a damping mechanism for damping buffering provided on the side of the connecting plate near the extension adjustment sleeve. A fixed plate is fixedly connected, and a bolt is slidably connected to the inner wall of the fixed plate. A sleeve spring is sleeved on the circumferential surface of the bolt, and a nut is threadedly connected to the circumferential surface of the bolt. When transporting oil through pipelines, the expansion and contraction of the compensating pipe is adjusted by rotating the nut and the bolt, thereby compensating for pipelines with different spacing, changing the axial thrust and angular compensation capabilities, achieving precise matching with thermal expansion and contraction, pipeline displacement, or power grid reactive power demand, reducing vibration and impact loads caused by thermal expansion or external impact, and thus extending the service life of pipelines, valves, and electrical equipment.

[0006] The first nut contacts the connecting plate near the telescopic adjustment sleeve, and the second bolt is slidably connected to the inner wall of the connecting plate. The sleeve spring contacts the side of the connecting plate near the telescopic adjustment sleeve, the sleeve spring contacts the side of the fixing plate near the telescopic adjustment sleeve, and the second nut contacts the side of the connecting plate away from the telescopic adjustment sleeve. A damping groove is formed on the circumferential surface of the first bolt. During compensation adjustment, to prevent the telescopic adjustment sleeve from shaking, a sleeve spring is fitted on the circumferential surface of the second bolt to provide elastic buffering for the compensation tube, preventing damage to the telescopic adjustment sleeve during adjustment. Allowing a certain amount of time or resources provides a "safety cushion" in case of unexpected delays, equipment failures, or fluctuations in demand, ensuring that the task can still be completed on time and avoiding errors or rework caused by rushing. The buffer time also allows for inspection and optimization, thereby improving delivery quality.

[0007] Preferably, the positioning buffer mechanism includes an annular plate, a trapezoidal plate fixedly connected to the outer surface of the annular plate, a sliding rod slidably connected to the inner wall of the compensation pipe, a roller rotatably connected to the inner wall of the sliding rod, a positioning block one fixedly connected to the circumferential surface of the compensation pipe, and a sealing plate rotatably connected to the inner wall of the positioning block one via a torsion spring. When the compensation pipe is connected to the oil pipe, the oil pressure inside the compensation pipe pushes the annular plate, causing the annular plate to drive the sealing plate to seal the interface between the compensation pipe and the oil pipe. This can accurately limit the compensation amount, avoid hose stretching out of control, seal aging or rupture due to excessive pipe displacement, thereby reducing the risk of leakage. The combined effects of limiting the compensation range, leak-proof sealing and real-time monitoring reduce axial thrust and vibration, significantly reduce wear on downstream equipment such as pipes and valves, and extend the overall system life.

[0008] Positioning blocks are fixedly connected to both sides of the connecting plate. An arc plate is rotatably connected to the inner wall of the positioning block via a torsion spring. An elastic telescopic rod is fixedly connected to the side of the arc plate near the oil pipe. A snap-fit ​​plate is fixedly connected to the elastic telescopic end of the elastic telescopic rod. The circumferential surface of the annular plate is slidably connected to the inner wall of the compensating pipe. The trapezoidal plate contacts the circumferential surface of the roller and moves on the trajectory of the roller. The top of the sliding rod is hinged to the sealing plate. The circumferential surface of the oil pipe interface contacts the sealing plate, and a rubber sealing sleeve is provided on the inner wall of the sealing plate. The snap-fit ​​plate contacts the circumferential surface of the oil pipe. When the compensating pipe is connected to the oil pipe, the arc plate drives the snap-fit ​​plate to approach the oil pipe for positioning. When vibration occurs, the snap-fit ​​plate will buffer the compensating pipe, so that the vibration energy is absorbed during transmission, significantly reducing the impact on downstream components such as pipelines, valves, and pumps, avoiding loosening, wear, or premature failure caused by vibration, maintaining the accuracy of axial and angular positions, thereby improving the positioning accuracy and operational stability of the overall system.

[0009] Preferably, the damping mechanism includes a bracket, and a movable rod is slidably connected to the inner wall of the bracket via a small spring. A wedge block is fixedly connected to the bottom of the movable rod, and a locking plate is fixedly connected to the top of the arc plate. When the compensation tube is positioned, the arc plate will drive the wedge block and the locking plate to lock themselves, which greatly reduces the actual position error, further suppresses the accumulation of error, can adjust the compensation parameters in real time, maintain stable positioning, and prevent positioning deviation caused by inertial displacement.

[0010] A cylinder is fixedly connected to the side of the connecting plate near the telescopic adjustment sleeve. A limit rod is slidably connected to the inner wall of the cylinder via a small spring. A damping plate is fixedly connected to the side of the limit rod near bolt one. The bracket is fixedly connected to the top of the arc plate. The inclined block contacts the inner wall of the bracket. The clamping plate contacts the bottom of the inclined block. The clamping plate contacts the inner wall of the bracket. When adjusting the compensating tube through bolt one, the movement of bolt one will cause it to contact the damping plate inside the limit rod through the damping groove on the circumferential surface for damping. This absorbs the transient vibrations and impact loads generated during the adjustment process, making the displacement or tension changes of the compensator smoother and significantly reducing the impact on downstream equipment such as pipelines and valves. This not only improves the dynamic stability of the equipment during operation but also improves the overall accuracy during adjustment.

[0011] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0012] 1. This compensator with adjustment function, through the coordinated operation of the compensating pipe, connecting plate, bolt one, nut one, oil pipe, telescopic adjustment sleeve, bolt two, fixing plate, sleeve spring, and nut two, allows for the contraction and adjustment of the compensating pipe during oil pipeline transportation by rotating nut one in conjunction with bolt one. This compensates for pipelines with different spacing, changes the axial thrust and angular compensation capacity, and achieves precise matching with thermal expansion and contraction, pipeline displacement, or power grid reactive power demand. It reduces vibration and impact loads caused by thermal expansion or external impacts, thereby extending the service life of pipelines, valves, and electrical equipment. During the adjustment process, to prevent the telescopic adjustment sleeve from wobbling, a sleeve spring is fitted around the circumference of bolt two to provide elastic buffering for the compensating pipe, preventing damage to the telescopic adjustment sleeve during adjustment. The reserved time or resources provide a "safety cushion" in case of unexpected delays, equipment failures, or demand fluctuations, ensuring that the task can still be completed on time and avoiding errors or rework caused by rushing. The buffer time also allows for inspection and optimization, thereby improving delivery quality.

[0013] 2. This compensator with adjustment function operates through the coordinated operation of annular plate, trapezoidal plate, roller, sliding rod, positioning block, and sealing plate. After the compensating pipe is connected to the oil pipe, the oil pressure inside the compensating pipe pushes the annular plate, causing the annular plate to drive the sealing plate to seal the interface between the compensating pipe and the oil pipe. It can accurately limit the compensation amount, avoid uncontrolled hose stretching, seal aging or rupture due to excessive pipeline displacement, thereby reducing the risk of leakage. The combined effects of limiting the compensation range, leak-proof sealing and real-time monitoring reduce axial thrust and vibration, significantly reduce wear on downstream equipment such as pipelines and valves, and extend the overall system life.

[0014] 3. This compensator with adjustment function works in coordination with positioning block two, arc plate, elastic telescopic rod and snap-fit ​​plate. When the compensating pipe is connected to the oil pipe, the arc plate drives the snap-fit ​​plate to move closer to the oil pipe for positioning. When vibration occurs, the snap-fit ​​plate will buffer the compensating pipe, so that the vibration energy is absorbed during transmission, which significantly reduces the impact on downstream components such as pipelines, valves, pumps, etc., avoids loosening, wear or premature failure caused by vibration, maintains the accuracy of axial and angular positions, and thus improves the positioning accuracy and operational stability of the overall system.

[0015] 4. This compensator with adjustment function, through the coordinated operation of the clamping plate, bracket, moving rod and inclined block, when positioning the compensation tube, the arc plate will drive the inclined block and the clamping plate to lock together, which greatly reduces the actual position error, further suppresses the accumulation of error, can adjust the compensation parameters in real time, maintain stable positioning, and prevent positioning deviation caused by inertial displacement.

[0016] 5. This compensator with adjustment function operates through the cooperation of the cylinder, the limiting rod, and the damping plate. When the compensator is adjusted by bolting a pair of compensator tubes, the movement of the bolt will cause the damping groove on the circumferential surface to contact the damping plate inside the limiting rod for damping, absorbing the transient vibration and impact load generated during the adjustment process. This makes the displacement or tension change of the compensator smoother, significantly reducing the impact on downstream equipment such as pipelines and valves. It not only improves the dynamic stability of the equipment during operation, but also improves the overall accuracy during adjustment. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-7One embodiment of the present invention is as follows: a compensator with an adjustment function includes a compensating pipe 1, an extension adjustment sleeve 6 installed on the inner wall of the compensating pipe 1, a connecting plate 2 fixedly connected to the circumferential surface of the compensating pipe 1, a bolt 3 slidably connected to the inner wall of the connecting plate 2, a nut 4 threadedly connected to the circumferential surface of the bolt 3, oil pipes 5 provided on the front and rear sides of the compensating pipe 1, positioning buffer mechanisms 7 for positioning buffering provided on both sides of the connecting plate 2, a damping mechanism 8 for damping buffering provided on the side of the connecting plate 2 near the extension adjustment sleeve 6, a fixing plate 10 fixedly connected to the circumferential surface of the compensating pipe 1, a bolt 9 slidably connected to the inner wall of the fixing plate 10, a sleeve spring 11 sleeved on the circumferential surface of the bolt 9, and a nut 12 threadedly connected to the circumferential surface of the bolt 9.

[0027] When transporting oil through pipelines, space constraints may arise when connecting pipelines. In such cases, it is necessary to connect the compensation pipe 1 to the middle of the oil pipe 5. At this time, the operator can rotate nut 4. Rotating nut 4 will push the connection port of compensation pipe 1 to slide along bolt 3 through the contact surface. This will cause compensation pipe 1 to drive the expansion and contraction adjustment sleeve 6 to adjust, thereby compensating for pipelines with different spacing, changing the axial thrust and angular compensation capabilities, achieving precise matching with thermal expansion and contraction, pipeline displacement or reactive power demand of the power grid, reducing vibration and impact loads caused by thermal expansion or external impacts, thereby extending the service life of pipelines, valves and electrical equipment.

[0028] Nut 14 is in contact with the connecting plate 2 on the side near the telescopic adjustment sleeve 6, and bolt 29 is slidably connected to the inner wall of the connecting plate 2; sleeve spring 11 is in contact with the side of the connecting plate 2 near the telescopic adjustment sleeve 6, sleeve spring 11 is in contact with the side of the fixing plate 10 near the telescopic adjustment sleeve 6, nut 212 is in contact with the side of the connecting plate 2 away from the telescopic adjustment sleeve 6, and a damping groove is provided on the circumferential surface of bolt 13.

[0029] While the compensation is being adjusted, to prevent the telescopic adjustment sleeve 6 from shaking, the second nut 12 is simultaneously rotated. At this time, the second nut 12 will push the fixed plate 10 to move through the contact surface. Because the circumferential surface of the second bolt 9 is fitted with a sleeve spring 11, when the compensation pipe 1 adjusts the oil, it will shake. At this time, the sleeve spring 11 will use its own elasticity to provide elastic buffer between the compensation pipe 1 and the connecting plate 2, avoiding damage to the telescopic adjustment sleeve 6 during adjustment. Allowing a certain amount of time or resources can provide a "safety cushion" in case of unexpected delays, equipment failures, or fluctuations in demand, ensuring that the task can still be completed on time, and avoiding errors or rework caused by rushing. The buffer time also allows for inspection and optimization, thereby improving the quality of delivery.

[0030] Working principle: When transporting oil through pipelines, the expansion and contraction of the compensation pipe 1 is adjusted by rotating nut 4 in conjunction with bolt 3, thereby compensating for pipelines with different spacing, changing the axial thrust and angular compensation capacity, and thus extending the service life of pipelines, valves and electrical equipment. While adjusting the compensation, to prevent the expansion and contraction sleeve 6 from shaking, a spring 11 is fitted on the circumferential surface of bolt 29 to provide elastic buffering for the compensation pipe 1, preventing damage to the expansion and contraction sleeve 6 during adjustment. A certain amount of time or resources are reserved to provide a "safety cushion" in case of unexpected delays, equipment failures, or fluctuations in demand, ensuring that the task can still be completed on time.

[0031] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the positioning buffer mechanism 7 includes an annular plate 71, a trapezoidal plate 72 fixedly connected to the outer surface of the annular plate 71, a sliding rod 74 slidably connected to the inner wall of the compensation tube 1, a roller 73 rotatably connected to the inner wall of the sliding rod 74, a positioning block 75 fixedly connected to the circumferential surface of the compensation tube 1, and a sealing plate 76 rotatably connected to the inner wall of the positioning block 75 via a torsion spring.

[0032] After the compensation pipe 1 is connected to the oil pipe 5, oil flows through the interior of the compensation pipe 1 through the oil pipe 5. At this time, a large pressure will be generated inside the compensation pipe 1, which will push the annular plate 71 through the oil pressure inside the compensation pipe 1. This will cause the annular plate 71 to drive the trapezoidal plate 72 to move. The trapezoidal plate 72 moves on the movement trajectory of the roller 73, and thus contacts the circumferential surface of the roller 73 through the inclined surface, thereby pushing the sliding rod 74 to move upward. The movement of the sliding rod 74 will drive the sealing plate 76 to rotate through the hinge point of the positioning block 75, so that the sealing plate 76 is close to the interface between the compensation pipe 1 and the oil pipe 5, thereby sealing the oil pipe 5. This can accurately limit the compensation amount, avoid the hose stretching out of control, seal aging or rupture due to excessive pipeline displacement, thereby reducing the risk of leakage. The combined effect of limiting the compensation range, leak-proof sealing and real-time monitoring reduces axial thrust and vibration, significantly reduces wear on downstream equipment such as pipelines and valves, and extends the overall system life.

[0033] Positioning blocks 77 are fixedly connected to both sides of the connecting plate 2. An arc plate 78 is rotatably connected to the inner wall of the positioning block 77 via a torsion spring. An elastic telescopic rod 79 is fixedly connected to the side of the arc plate 78 near the oil pipe 5. A snap-fit ​​plate 710 is fixedly connected to the elastic telescopic end of the elastic telescopic rod 79. The circumferential surface of the annular plate 71 is slidably connected to the inner wall of the compensating pipe 1. The trapezoidal plate 72 is in contact with the circumferential surface of the roller 73, and the trapezoidal plate 72 moves on the movement trajectory of the roller 73. The top of the sliding rod 74 is hinged to the sealing plate 76. The circumferential surface of the interface of the oil pipe 5 is in contact with the sealing plate 76, and a rubber sealing sleeve is provided on the inner wall of the sealing plate 76. The snap-fit ​​plate 710 is in contact with the circumferential surface of the oil pipe 5.

[0034] While the compensating pipe 1 is being connected to the oil pipe 5, the arc plate 78 will rotate and move closer to the oil pipe 5 via the torsion spring between the positioning blocks 77. At this time, the arc plate 78 will drive the elastic telescopic rod 79 to rotate, and the elastic telescopic rod 79 will drive the snap-fit ​​plate 710 to move closer to the oil pipe 5 for positioning. When vibration occurs, the snap-fit ​​plate 710 will buffer the compensating pipe 1, so that the vibration energy is absorbed during transmission, significantly reducing the impact on downstream components such as pipelines, valves, and pumps, avoiding loosening, wear, or premature failure caused by vibration, maintaining the accuracy of axial and angular positions, thereby improving the positioning accuracy and operational stability of the overall system.

[0035] Working principle: After the compensation pipe 1 is connected to the oil pipe 5, the oil pressure inside the compensation pipe 1 pushes the annular plate 71, causing the annular plate 71 to drive the sealing plate 76 to seal the interface between the compensation pipe 1 and the oil pipe 5. This can accurately limit the compensation amount, avoid uncontrolled stretching of the hose, aging of the seal or rupture due to excessive pipeline displacement, thereby reducing the risk of leakage. The combined effect of limiting the compensation range, preventing leakage and sealing and real-time monitoring extends the overall system life. When the compensation pipe 1 is connected to the oil pipe 5, the arc plate 78 drives the snap-fit ​​plate 710 to approach the oil pipe 5 for positioning. When vibration occurs, the snap-fit ​​plate 710 will buffer the compensation pipe 1, so that the vibration energy is absorbed during transmission, significantly reducing the impact on downstream components such as pipelines, valves, and pumps, and avoiding loosening, wear or premature failure caused by vibration.

[0036] The damping mechanism 8 includes a bracket 82, a movable rod 83 is slidably connected to the inner wall of the bracket 82 by a small spring, an inclined block 84 is fixedly connected to the bottom of the movable rod 83, and a clamping plate 81 is fixedly connected to the top of the arc plate 78.

[0037] While positioning the compensation tube 1, the arc plate 78 will drive the clamping plate 81 and the bracket 82 to move closer to each other. Thus, the left arc plate 78 rotates, causing the clamping plate 81 to rotate, and the right arc plate 78 drives the bracket 82 to rotate. The bracket 82 drives the moving rod 83 to rotate, and the moving rod 83 drives the inclined block 84 to rotate, thereby making the clamping plate 81 and the inclined block 84 hinged. The clamping plate 81 drives the inclined block 84 to move through the inclined surface. When the inclined surface of the clamping plate 81 leaves the inclined surface of the inclined block 84, the inclined block 84 will be reset by the small spring between it and the bracket 82. Thus, the inclined block 84 and the clamping plate 81 self-lock the arc plate 78, which greatly reduces the actual position error, further suppresses the accumulation of error, can adjust the compensation parameters in real time, maintain stable positioning, and prevent positioning deviation caused by inertial displacement.

[0038] A cylinder 85 is fixedly connected to the side of the connecting plate 2 near the telescopic adjustment sleeve 6. A limit rod 86 is slidably connected to the inner wall of the cylinder 85 through a small spring. A damping plate 87 is fixedly connected to the side of the limit rod 86 near the bolt 3. The bracket 82 is fixedly connected to the top of the arc plate 78. The inclined block 84 contacts the inner wall of the bracket 82. The clamping plate 81 contacts the bottom of the inclined block 84. The clamping plate 81 contacts the inner wall of the bracket 82.

[0039] When adjusting the compensating pipe 1 via bolt 3, bolt 3 slides along the connecting plate 2. As bolt 3 moves, it contacts the damping plate 87 inside the limiting rod 86 through the damping groove on the circumferential surface. The damping groove of bolt 3 pushes the damping plate 87 to move through the inclined surface. When the damping plate 87 enters the next damping groove, it is reset by the spring between the damping plate 87 and the limiting rod 86, thereby damping bolt 3 and absorbing the transient vibration and impact load generated during the adjustment process. This makes the displacement or tension change of the compensator smoother and significantly reduces the impact on downstream equipment such as pipelines and valves. It not only improves the dynamic stability of the equipment during operation but also improves the overall accuracy during adjustment.

[0040] Working principle: When positioning the compensation tube 1, the arc plate 78 will drive the inclined block 84 and the clamping plate 81 to lock themselves, which will greatly reduce the actual position error and further suppress the accumulation of error. It can adjust the compensation parameters in real time, maintain stable positioning, and prevent positioning deviation caused by inertial displacement. When adjusting the compensation tube 1 by bolt 3, the movement of bolt 3 will contact the damping plate 87 inside the limit rod 86 through the damping groove on the circumferential surface for damping, absorbing the transient vibration and impact load generated during the adjustment process, making the displacement or tension change of the compensator smoother and improving the overall accuracy during adjustment.

[0041] This invention provides a compensator with adjustment function. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technology.
