Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] In the present invention, the accompanying drawings are only used to show the specific structure and its connection relationship, which are only schematic and do not represent the specific dimensions and the proportional relationship between parts.

[0023] An embodiment of a shock-absorbing support hanger for a gas pipeline of the present invention, as Figures 1 to 16 shown, includes a housing 100, two vertical shock-absorbing devices 200 and two horizontal shock-absorbing devices 300; The housing 100 is arranged vertically, and a receiving cavity 101 is provided inside the housing 100; the receiving cavity 101 is arranged front and back for placing the pipeline 500; a limiting frame 110 is also provided in the receiving cavity 101, and the four sides of the limiting frame 110 are in contact with the pipeline 500. Two horizontal shock-absorbing devices 300 are symmetrically arranged left and right. The horizontal shock-absorbing device 300 includes a horizontal damping cylinder 310 and an adjusting component 320; the horizontal damping cylinder 310 is opened in the housing 100; a horizontal piston 311 and a damping regulator 314 are movably arranged left and right in the horizontal damping cylinder 310; a first flow port 312 is provided on the horizontal piston 311, and the horizontal piston 311 is connected to the limiting frame 110; the damping regulator 314 is located on the side of the horizontal piston 311 away from the limiting frame 110, and there is a certain distance between them in the initial state. When there is left-right vibration, the horizontal piston 311 on the corresponding side approaches the damping regulator 314 until they contact. Before they contact is the first shock-absorbing stage, and after they contact is the second shock-absorbing stage; a second flow port 315 is provided on the damping regulator 314; during the second shock-absorbing stage, the first flow port 312 is blocked; a first baffle 316 is rotatably installed in the damping regulator 314. When the first baffle 316 rotates, the area of the first baffle 316 coinciding with the second flow port 315 changes; the adjusting component 320 includes a hinged rod 321, a transmission rod 322, a torsion spring 324 and a gear 325; one end of the hinged rod 321 is hinged to the horizontal piston 311; one end of the torsion spring 324 is fixedly connected to the horizontal piston 311, and the other end is fixedly connected to the hinged rod 321; the transmission rod 322 includes a connected horizontal section and a vertical section, and the horizontal section is hinged to the other end of the hinged rod 321; a rack 323 is provided at the lower end of the vertical section; the gear 325 is fixedly installed on the first baffle 316, and the rack 323 meshes with the gear 325. When the housing 100 vibrates in the horizontal direction, the horizontal piston 311 moves in the horizontal damping cylinder 310, and the horizontal piston 311 approaches the damping regulator 314. During this process, the hinged rod 321 rotates, driving the transmission rod 322 to move in the vertical direction. The rack 323 moves synchronously with the transmission rod 322, and the gear 325 drives the first baffle 316 to rotate. The area of the first baffle 316 coinciding with the second flow port 315 gradually increases, and the area of the second flow port 315 for the damping liquid to pass through decreases, thereby increasing the damping in the horizontal direction.

[0024] Two vertical shock-absorbing devices 200 are symmetrically arranged up and down. The vertical shock-absorbing device 200 includes a first vertical damping cylinder 210 and a first vertical piston 211; the first vertical damping cylinder 210 is movably installed up and down on the housing 100, and the first vertical piston 211 is movably installed up and down in the first vertical damping cylinder 210; a flow port is provided on the first vertical piston 211; the first vertical piston 211 is connected to the limiting frame 110.

[0025] In this embodiment, the shock-absorbing support hanger further includes a gravity adjustment structure 400; a second baffle 317 is rotatably installed in the damping regulator 314, and when the gravity of the pipeline 500 increases, the gravity adjustment structure 400 drives the second baffle 317 to rotate. As the second baffle 317 rotates unidirectionally, the area of the second baffle 317 overlapping with the second flow port 315 gradually increases; thus, when there is a horizontal vibration, the horizontal damping force received by the pipeline 500 increases, thereby achieving the effect of shock absorption.

[0026] In this embodiment, the gravity adjustment structure 400 includes a connecting frame 410, two adjusting rods 411, and two sensing frames 412; the two adjusting rods 411 are respectively located on the left and right sides of the pipeline 500, the adjusting rods 411 are installed on the casing 100 so as to move up and down, and are located on the same horizontal plane as the center of the pipeline 500; the two sensing frames 412 are respectively located on the upper and lower sides of the pipeline 500; one end of the sensing frame 412 facing the pipeline 500 abuts against the pipeline 500; the sensing frame 412 and the adjusting rod 411 are connected by the connecting frame 410; the second baffle 317 is connected with a telescopic rod 430, and the telescopic rod 430 rotates synchronously with the second baffle 317; the telescopic rod 430 is rotatably installed on the casing 100, and the other end of the telescopic rod 430 is connected with a moving rod 431, and the moving rod 431 is in threaded transmission with the telescopic rod 430; one end of the moving rod 431 in contact with the adjusting rod 411 is a slope, and the distance from the upper end to the pipeline 500 is less than the distance from the lower end to the pipeline 500. When the mass of the pipeline 500 increases, the sensing frame 412 moves downward, driving the connecting frame 410 to move downward, and further causing the adjusting rod 411 to move downward. When the adjusting rod 411 moves downward, it contacts the slope of the moving rod 431, causing the moving rod 431 to move towards the pipeline 500. Since the moving rod 431 is threadedly connected to the telescopic rod 430, the horizontal movement of the moving rod 431 drives the telescopic rod 430 to rotate, and further drives the second baffle 317 to rotate, thereby increasing the area of the second baffle 317 overlapping with the second flow port 315, further reducing the area for the damping liquid to pass through, and increasing the damping force in the second shock-absorbing stage.

[0027] In this embodiment, a blocking block 413 is provided in the middle of the induction frame 412. One end of the blocking block 413 away from the pipeline 500 is fixedly connected to a first spring 414, and the other end of the first spring 414 is fixedly connected to the machine shell 100. A U-shaped frame 415 with an opening facing the pipeline 500 is connected to the induction frame 412. The upper and lower U-shaped frames 415 are connected by two connection structures. The connection structure includes four connecting rods 421. The four connecting rods 421 are connected end to end to form a rhombus structure. The two ends of the connecting rod 421 are respectively hinged to two adjacent connecting rods 421, and one end of the connecting rod 421 is hinged to the U-shaped frame 415 and one end is hinged to the adjusting rod 411. The adjusting rod 411 is telescopic. So that in both the case of vibration and the case of no vibration of the machine shell 100, the horizontal plane where the center of the pipeline 500 is located is approximately the same. Furthermore, the vertical position of the first vertical damping cylinder 210 remains unchanged, preventing the pipeline 500 from hitting the cylinder during up and down vibration and reducing the damage to the pipeline 500. And it enables the gravity adjustment mechanism to more accurately sense the mass change of the pipeline 500, and then change the damping magnitude in the second damping stage, further improving the damping effect.

[0028] In this embodiment, two second vertical damping cylinders 120 are provided on the machine shell 100. The two second vertical damping cylinders 120 are located on the upper and lower sides of the pipeline 500. A second vertical piston 121 is installed in the second vertical damping cylinder 120 to move up and down. One end of the second vertical piston 121 facing the pipeline 500 is connected to an installation rod 122. The other end of the installation rod 122 is connected to the blocking block 413. A blocking plate 123 is provided on the side of the second vertical piston 121 away from the pipeline 500, and small holes are provided in the blocking plate 123. The blocking plate 123 is hinged to the machine shell 100. When the pipeline 500 moves downward relative to the outer shell, the upper blocking plate 123 divides the second vertical damping cylinder 120 where it is located into upper and lower parts. When the pipeline 500 moves upward relative to the outer shell, the lower blocking plate 123 divides the second vertical damping cylinder 120 where it is located into upper and lower parts. The second vertical piston 121 moves in the second vertical damping cylinder 120. When the machine shell 100 moves upward relative to the pipeline 500, the lower blocking plate 123 rotates under the action of the damping liquid, dividing the lower second vertical damping cylinder 120 into upper and lower ends. The damping liquid can only flow through the small holes in the center of the blocking plate 123. At this time, the damping of the lower end is larger, consuming the vibration energy. When the machine shell 100 moves downward relative to the pipeline 500, the upper blocking plate 123 rotates under the action of the damping liquid, dividing the upper second vertical damping cylinder 120 into upper and lower ends. The damping liquid can only flow through the small holes in the center of the blocking plate 123. At this time, the damping of the upper end is larger, consuming the vibration energy; until the energy is exhausted.

[0029] In this embodiment, the damping regulator 314 is connected to a second spring 319, and the other end of the second spring 319 is connected to the machine housing 100; a third spring 432 is sleeved on the moving rod 431; one end of the third spring 432 is connected to the moving rod 431, and the other end is connected to the machine housing 100. When the vibration disappears, the shock-absorbing support hanger is reset to prepare for the next shock absorption.

[0030] In this embodiment, a plug block is provided at one end of the telescopic rod 430 facing the second baffle 317; a jack 318 is provided at the corresponding position of the second baffle 317; the plug block is inserted into the jack 318 so that the telescopic rod 430 and the second baffle 317 rotate synchronously.

[0031] In this embodiment, a horizontal support rod 313 is connected to the side of the horizontal piston 311 facing the limit frame 110, and the horizontal support rod 313 is connected to the limit frame 110 so as to move up and down; a vertical support rod 212 is connected to one end of the first vertical piston 211 facing the limit frame 110, and the vertical support rod 212 is connected to the limit frame 110 so as to move left and right. This avoids jamming during the vibration process.

[0032] In this embodiment, sliding grooves are provided on all four sides of the limit frame 110; clamping blocks 213 are provided at one ends of the horizontal support rod 313 and the vertical support rod 212 facing the limit frame 110; the clamping blocks 213 are slidably installed in the sliding grooves to prevent the horizontal support rod 313 and the vertical support rod 212 from detaching from the limit frame 110.

[0033] Combining the above embodiments, the working principle and process of the present invention are as follows: When the workshop where the gas pipeline support is located vibrates, the machine housing 100 vibrates synchronously with the wall; the energy in the vertical direction of the machine housing 100 is offset by the vertical shock-absorbing device 200; the energy in the horizontal direction is offset by the horizontal shock-absorbing device 300; since the energy of the longitudinal wave is relatively low, the energy transmitted by the vertical vibration can be offset through a damping process; while the energy transmitted by the vibration on the horizontal plane is relatively large, so the operation of the horizontal shock-absorbing device 300 is divided into a first shock-absorbing stage and a second shock-absorbing stage; the energy transmitted by the vibration is fully offset, avoiding the occurrence of the pipe body falling off the support due to vibration, and at the same time avoiding the damage to the pipeline 500 caused by the vibration.

[0034] When the housing 100 vibrates in the horizontal direction, the horizontal piston 311 moves within the horizontal damping cylinder 310. As the horizontal piston 311 approaches the damping adjuster 314, during this process, the articulated rod 321 rotates, driving the adjusting rod 411 to move in the vertical direction. The rack 323 moves synchronously with the adjusting rod 411, and the gear 325 drives the first baffle 316 to rotate, thereby increasing the area of overlap between the first baffle 316 and the second flow port 315. At the same time, the damping fluid flows through the larger first flow port 312 to counteract the energy transmitted by the vibration to the pipeline 500. When the vibration amplitude is large, the horizontal piston 311 fits against the damping adjuster 314, blocking the first flow port 312. At this time, the damping fluid can only flow through the smaller second flow port 315. Moreover, the larger the vibration amplitude, the smaller the area of the second flow port 315, the greater the damping, and the stronger the shock absorption effect.

[0035] When the housing 100 vibrates vertically, the first vertical piston 211 moves within the first vertical damping cylinder 210, and the second vertical piston 121 moves within the second vertical damping cylinder 120. When the housing 100 moves upward relative to the pipeline 500, the lower blocking plate 123 rotates under the action of the damping fluid, dividing the lower second vertical damping cylinder 120 into upper and lower sections. The damping fluid can only flow through the small hole in the center of the blocking plate 123. At this time, the damping in the lower section is greater, consuming the vibration energy. When the housing 100 moves downward relative to the pipeline 500, the upper blocking plate 123 rotates under the action of the damping fluid, dividing the upper second vertical damping cylinder 120 into upper and lower sections. The damping fluid can only flow through the small hole in the center of the blocking plate 123. At this time, the damping in the upper section is greater, consuming the vibration energy; until all the energy is consumed.

[0036] When the mass of the pipeline 500 increases, the induction frame 412 moves downward, driving the U-shaped frame 415 downward, and further causing the adjusting rod 411 to move downward. When the adjusting rod 411 moves downward, it contacts the inclined surface of the moving rod 431, causing the moving rod 431 to move towards the pipeline 500. Since the moving rod 431 is threadedly connected to the telescopic rod 430, the horizontal movement of the moving rod 431 drives the telescopic rod 430 to rotate, and then drives the second baffle 317 to rotate through the insertion block and the insertion hole 318, thereby further reducing the area of the second flow port 315 and increasing the damping in the second shock absorption stage. When the vibration is relatively intense, part of the energy is offset in the first shock absorption stage, and the remaining energy is offset in the second shock absorption stage. The present invention can change the damping in the second shock absorption stage according to the mass and vibration speed of the pipeline 500, thereby offsetting the remaining energy.

[0037] Furthermore, when the amplitudes are consistent in the vertical direction, since the four connecting rods 421 are connected end to end to form a rhombus structure, the adjusting rod 411 is the diagonal of the rhombus structure and is telescopic. Through the connecting frame 410, the U-shaped frame 415, the induction frame 412, and the vertical support rod 212, it is connected to the pipeline 500, so that the center horizontal plane of the pipeline 500 is approximately the same in both the vibration and non-vibration cases of the casing 100. Furthermore, the vertical position of the first vertical damping cylinder 210 remains unchanged, preventing the pipeline 500 from hitting the cylinder during up and down vibrations and reducing damage to the pipeline 500; and enabling the gravity adjustment mechanism to more accurately sense changes in the mass of the pipeline 500, thereby changing the damping magnitude in the second shock absorption stage and further improving the shock absorption effect.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
