Description

Technical Field

[0001] The invention relates to the technical field of spring supports and hangers, in particular to an ultra-large displacement constant force spring support and hanger. Background Art

[0002] Constant-force spring supports and hangers are designed based on the principle of moment balance. Within the permitted load displacement, the load torque and spring torque remain in equilibrium. Constant-force spring supports and hangers provide constant support force to the pipes and equipment supported by them during displacement, thus preventing additional stress on the pipes and equipment. Constant-force spring supports and hangers are generally used where displacement stress reduction is necessary, such as in power station boilers, suspended steam, water, smoke, and air ducts and burners in power plants, and in other applications within the petroleum and chemical industries.

[0003] The constant force spring support hanger supports the pipeline through the spring set inside. The pressure carried by the support hanger for different pipes is also different. Since the spring inside the support hanger is often unable to be replaced, it is often necessary to select supports and hangers of different specifications. In addition, the screw at the top of the support hanger needs to be manually rotated and lifted by the operator, which is inefficient and inconvenient to adjust for pipelines with a large support height.

The end of 05 conflicts with the inner side of the shell 1, and a conflict groove 206 is provided on the inner side of the shell 1. A guide groove 210 is provided on the inner side of the shell 1. A lifting slider 211 is fixedly connected to the side of the lifting seat 203, and the lifting slider 211 is slidably connected to the shell 1 through the guide groove 210. Two blocking rods 207 are respectively connected to the two sides of the shell 1 in parallel and sliding manner. The blocking rod 207 and the guide groove 210 are arranged perpendicular to each other. A second spring 212 is fixedly connected between the end of the blocking rod 207 and the shell 1. A bevel groove 209 is provided on the side of the blocking rod 207, and the bevel groove 209 is a right-angled trapezoidal structure;

[0038] The lifting seat 203 in the middle of the shell 1 is provided with a threaded column 201 that can be adjusted in height on the inner side of the lifting seat 203, which is used to adjust the height of the support seat 202 to support the pipe. In order to facilitate the adjustment of the position of the threaded column 201, two threaded sliders 204 are provided on the inner side of the lifting seat 203. The threaded sliders 204 are threadedly connected to the threaded column 201. The height of the threaded sliders 204 can be adjusted by rotating the threaded column 201. When the height of the threaded column 201 needs to be changed in a large range, the user can lift the threaded column 201 to the top side so that the interference rod 205 on the side of the threaded slider 204 moves to the interference groove 206 and interferes with the inner side of the shell 1. At this time, under the push of the first spring 208, the threaded slider 204 is released from the threaded connection state with the threaded column 201. At this time, the user can directly lift and lower the threaded column 201. The lifting bracket 203 is conveniently positioned to the user, and the user can adjust the height of the lifting bracket 203 by pressing the blocking rod 207 and the lifting slider 211. The lifting slider 211 is connected to the outer shell 1 through the guide groove 210 by the blocking rod 207. The blocking rod 207 blocks the sliding of the lifting slider 211. The inclined groove 209 on the blocking rod 207 allows the user to move the lifting bracket 203 from bottom to top. When the lifting slider 211 conflicts with the blocking rod 207 on the top side, the interference rod 205 conflicts with the interference groove 206, which is convenient for maintaining the position of the lifting bracket 203 and adjusting the height of the threaded column 201. After completing the rough adjustment of the height of the threaded column 201, press the blocking rod 207 and push the lifting bracket 203 down. At this time, the lifting slider 211 conflicts with the blocking rod 207 on the bottom side, so that the lifting bracket 203 remains in the initial position, which is convenient for adjusting the supporting effect of the support bracket.

[0039] Specifically, such as Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 10As shown, the disassembly structure 3 includes a side cover plate 301, a side of the housing 1 is provided with a side cover plate 301, the end of the blocking rod 207 conflicts with the side cover plate 301, a side of the housing 1 is provided with a snap-fitting groove 305, the inner side of the side cover plate 301 is slidably connected with a snap-fitting plate 306, the end of the snap-fitting plate 306 is snap-fitted with the housing 1 through the snap-fitting groove 305, a third spring 304 is fixedly connected between the snap-fitting plate 306 and the side cover plate 301, and a limited number of springs are provided on the side cover plate 301. The side cover 301 is slidably connected to a carrier plate 307 through the limiting groove 302. The carrier plate 307 and the side cover 301 are arranged perpendicular to each other. A plurality of expansion rods 308 are slidably connected to the carrier plate 307. The plurality of expansion rods 308 are arranged in a circle. A fourth spring 309 is fixedly connected between the side of the expansion rod 308 and the carrier plate 307. A support spring 303 is provided on the carrier plate 307. The expansion rod 308 conflicts with the inner side of the support spring 303.

[0040] A side cover 301 is provided on the side of the housing 1, and a bearing plate 307 with a support spring 303 is slidably provided on the side cover 301. The side cover 301 is fixed to the snap groove 305 on the housing 1 through the snap plate 306 on the top side. When the side cover 301 is in a closed state, the inner side of the side cover 301 pushes the blocking rod 207, so that the inclined groove 209 on the blocking rod 207 is connected to the guide groove 210. At this time, the lifting seat 203 can freely move up and down in height. When the side cover 301 is opened, the blocking rods 207 on both sides are pushed by the second spring 212 It will automatically pop up, thereby playing a positioning effect on the lifting seat 203. On the other hand, according to the support needs of different pipes, users can choose different support springs 303 for support. The support spring 303 can be fixed by the expansion rod 308 on the supporting plate 307, so that the expansion rod 308 is placed in the middle of the support spring 303. Under the push of the fourth spring 309, the expansion rod 308 will fix the support spring 303 to the middle position of the supporting plate 307, and the top of the support spring 303 will support the bottom side of the lifting seat 203, thereby providing a supporting effect for the pipe.

[0041] Specifically, such as Figure 1 、 Figure 2 、 Figure 8As shown, the supporting structure 4 includes a thread groove 408, a thread groove 408 is provided on the bottom side of the shell 1, and the shell 1 is threadedly connected to a lifting stud 402 through the thread groove 408, and the top of the lifting stud 402 conflicts with the bearing plate 307, and a transmission groove 406 is provided on the side of the lifting stud 402, and the lifting stud 402 is slidingly connected to a driving ring 403 through the transmission groove 406, and the driving ring 403 is rotatably connected to the shell 1, and a tooth groove 407 is provided on the side of the driving ring 403, and the side of the driving ring 403 is meshed with a second bevel gear 405 through the tooth groove 407, and the second bevel gear 405 is rotatably connected to the shell 1, and the side of the second bevel gear 405 is meshed with a first bevel gear 404, and the middle part of the first bevel gear 404 is rotatably connected to the rocker 401, and the rocker 401 is rotatably connected to the shell 1;

[0042] The lengths of support springs 303 of different models may be different. At this time, in order to ensure that the support springs 303 can fully exert their supporting effect, the bottom side of the supporting plate 307 is in conflict with the top of the lifting stud 402. The user can rotate the rocker 401 located on the side of the shell 1. The rocker 401 drives the driving ring 403 on the lifting stud 402 to rotate through the transmission effect of the first bevel gear 404 and the second bevel gear 405. The driving ring 403 slides with the lifting stud 402 through the transmission groove 406. As the driving ring 403 rotates, the lifting stud 402 rotates in the threaded groove 408, and the height of the supporting plate 307 can be adjusted. Since the lifting seat 203 can slide freely after the side cover 301 is closed, the lifting seat 203 will automatically slide to the bottom and conflict with the top of the support spring 303, so that the user can freely adjust the position of the support spring 303 inside the shell 1 according to the length of the support spring 303 and the support height of the pipe. It is more flexible to use and has sufficient buffer distance when facing the need for large displacement support.

[0043] Specifically, such as Figure 1 、 Figure 4 、 Figure 9As shown, the adjustment structure 5 includes a gear ring 502, the top of the threaded column 201 is rotatably connected to the support seat 202, the threaded column 201 is fixedly connected to the gear ring 502, the side of the gear ring 502 is meshed with a third bevel gear 505, the third bevel gear 505 is rotatably connected to the support seat 202, the side of the third bevel gear 505 is meshed with a fourth bevel gear 506, the middle part of the fourth bevel gear 506 is fixedly connected to a handwheel 507, and the handwheel 507 is rotatably connected to the support seat 202, the gear ring 502 is provided with a positioning tooth block 503 on the side facing away from the third bevel gear 505, the side of the positioning tooth block 503 is meshed with the gear ring 502, the other side of the positioning tooth block 503 is fixedly connected to the support seat 202 with a fifth spring 504, the side of the positioning tooth block 503 is in contact with the adjusting rod 501, and the adjusting rod 501 is threadedly connected to the support seat 202;

[0044] After completing the fixing of the side cover 301 and the rough adjustment of the extended height of the threaded column 201, in order to accurately control the support height, the user can turn the handwheel 507 located on the side of the support seat 202. The rotation of the handwheel 507 will drive the threaded column 201 to rotate through the gear ring 502 through the transmission effect of the third bevel gear 505 and the fourth bevel gear 506, thereby accurately adjusting the height of the support seat 202. At the same time, in order to facilitate the lifting or lowering of the threaded column 201 when the threaded column 201 is not in contact with the threaded slider 204, an adjusting rod 501 is provided on the other side of the support seat 202. When the adjusting rod 501 is rotated, the end of the adjusting rod 501 will push the positioning tooth block 503 to engage with the gear ring 502. At this time, the threaded column 201 and the support seat 202 can be relatively fixed, which is convenient for operation.

[0045] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 10 、 Figure 11 As shown, the positioning structure 6 includes a first side block 603, and the two sides of the housing 1 are respectively fixedly connected to the first side blocks 603, and the two sides of the support seat 202 are respectively fixedly connected to the second side blocks 604, and the middle part of the second side block 604 is slidably connected to a positioning column 605, and a sixth spring 606 is fixedly connected between the positioning column 605 and the support seat 202.

The end of the positioning column 605 conflicts with the synchronization rod 601 through the positioning groove 607, and the side of the synchronization rod 601 is provided with a slot 602;

[0046] The support seat 202 is used to support the pipe, and the support seat 202 and the threaded column 201 can be rotated. In order to ensure that the support seat 202 does not change while adjusting the threaded column 201, a first side block 603 and a second side block 604 are respectively provided on the side of the support seat 202 and the housing 1. When it is necessary to rotate the hand wheel 507 to adjust the height of the threaded column 201, the user can install the synchronization rod 601 on the first side block 603 and the second side block 604 provided on the same side. The side of the synchronization rod 601 is provided with a slot 602. When installing, first Rotate the support seat 202 and the shell 1 until they are aligned, then slide the first side block 603 into the interior of the synchronization rod 601, and then slide and adjust the position of the synchronization rod 601 so that the second side block 604 slides from the slot 602 into the inside of the synchronization rod 601, and finally slide the synchronization rod 601 so that the end of the positioning column 605 at the end of the second side block 604 engages with the positioning groove 607 on the synchronization rod 601 to complete the installation of the synchronization rod 601. Due to the restriction of the synchronization rod 601, the support seat 202 will maintain its initial orientation while changing in height, ensuring support for the pipeline after the adjustment is completed.

[0047] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the connection structure 7 includes a first fixing sleeve 701, a first fixing sleeve 701 is provided on the top side of the support base 202, a second fixing sleeve 702 is installed on the top side of the first fixing sleeve 701, a connecting groove 704 is opened on the top side of the support base 202, a connecting block 703 is fixedly connected to the bottom side of the first fixing sleeve 701, a plurality of pulleys 705 are rotatably connected to the bottom side of the connecting block 703, and the pulleys 705 are rollingly connected to the support base 202 through the connecting grooves 704. Seventh springs 706 are fixedly connected between the two ends of the connecting block 703 and the support base 202 respectively.

[0048] Due to the thermal expansion and contraction of the pipeline, the length of the pipeline will change slightly with the change of temperature. Directly fixing the pipeline to the support bracket may reduce its lifespan under long-term use. A first fixing sleeve 701 and a second fixing sleeve 702 are provided on the support seat 202 for fixing the pipeline, and a connecting block 703 is provided on the bottom side of the first fixing sleeve 701. The connecting block 703 slides in the connecting groove 704 in the support seat 202 through the pulley 705 on the bottom side. Through the setting of the connecting groove 704, the pipeline has a certain lateral movement space when fixed, which effectively reduces the impact of temperature and improves the support effect.

[0049] When the present invention is in use, first, a height-adjustable threaded column 201 is provided on the inner side of the lifting seat 203 located in the middle of the shell 1, which is used to adjust the height of the support seat 202 to support the pipe. In order to facilitate the adjustment of the position of the threaded column 201, two threaded sliders 204 are provided on the inner side of the lifting seat 203. The threaded sliders 204 are threadedly connected to the threaded column 201. The height of the threaded sliders 204 can be adjusted by rotating the threaded column 201. When the height of the threaded column 201 needs to be changed in a large range, the user can lift the threaded column 201 to the top side, so that the interference rod 205 on the side of the threaded slider 204 moves to contact the inner side of the shell 1 through the interference groove 206. At this time, under the push of the first spring 208, the threaded slider 204 is The threaded slider 204 releases the threaded connection state with the threaded column 201. At this time, the user can directly lift and lower the threaded column 201, thereby improving the placement efficiency of the support bracket. On the other hand, a blocking rod 207 is provided on the inner side of the shell 1. The lifting slider 211 on the side of the lifting seat 203 is slidably connected to the shell 1 through the guide groove 210, and the blocking rod 207 blocks the sliding of the lifting slider 211. The inclined groove 209 provided on the blocking rod 207 allows the user to move the lifting seat 203 from bottom to top. When the lifting slider 211 conflicts with the blocking rod 207 on the top side, the conflicting rod 205 conflicts with the conflicting groove 206, which facilitates maintaining the position of the lifting seat 203 and thus adjusting the height of the threaded column 201, completing the adjustment of the threaded column 201. The lifting platform 203 is then moved downwards to the upper and lower portions of the support frame 201. The lifting platform 203 is then moved downwards to the upper and lower portions of the support frame 201. The lifting platform 203 is then moved downwards to the upper and lower portions of the support frame 201. When the plate 301 is opened, the blocking rods 207 on both sides will automatically pop out under the push of the second spring 212, thereby playing a positioning effect on the lifting seat 203. On the other hand, according to the support needs of different pipes, the user can choose different support springs 303 for support. The support spring 303 can be fixed by the expansion rod 308 on the supporting plate 307, so that the expansion rod 308 is placed in the middle of the support spring 303. Under the push of the fourth spring 309, the expansion rod 308 will fix the support spring 303 to the middle position of the supporting plate 307. The top of the support spring 303 will support the bottom side of the lifting seat 203, thereby providing a supporting effect for the pipe. For different models of support springs 303, the lengths may be inconsistent. At this time,In order to ensure that the support spring 303 fully exerts its supporting effect, the bottom side of the carrying plate 307 conflicts with the top of the lifting stud 402. The user can rotate the rocker 401 located on the side of the shell 1. The rocker 401 drives the driving ring 403 on the lifting stud 402 to rotate through the transmission effect of the first bevel gear 404 and the second bevel gear 405. The driving ring 403 slides with the lifting stud 402 through the transmission groove 406. As the driving ring 403 rotates, the lifting stud 402 rotates in the threaded groove 408, and the height of the carrying plate 307 can be adjusted. Since the lifting seat 203 can slide freely after the side cover 301 is closed, the lifting seat 203 will automatically slide to the bottom and conflict with the top of the support spring 303, so that the user can adjust the height of the carrying plate 307. The user can freely adjust the position of the support spring 303 inside the housing 1 according to the length of the support spring 303 and the support height of the pipe, which is more flexible to use and has sufficient buffer distance when facing the need for large displacement support. After completing the fixation of the side cover 301 and the rough adjustment of the extended height of the threaded column 201, in order to accurately control the support height, the user can turn the handwheel 507 on the side of the support seat 202. The rotation of the handwheel 507 is transmitted through the third bevel gear 505 and the fourth bevel gear 506, and finally drives the threaded column 201 to rotate through the gear ring 502, thereby accurately adjusting the height of the support seat 202. At the same time, in order to facilitate the adjustment of the threaded column 201 when the threaded slider 204 is not in contact with the threaded column 201, The column 201 is lifted or lowered, and an adjusting rod 501 is provided on the other side of the support seat 202. When the adjusting rod 501 is rotated, the end of the adjusting rod 501 will push the positioning tooth block 503 to engage with the tooth ring 502. At this time, the threaded column 201 and the support seat 202 can be relatively fixed, which is convenient for operation. The support seat 202 is used to support the pipeline, and the support seat 202 and the threaded column 201 can be rotated. In order to ensure that the support seat 202 does not change while adjusting the threaded column 201, a first side block 603 and a second side block 604 are respectively provided on the sides of the support seat 202 and the housing 1. When it is necessary to rotate the hand wheel 507 to adjust the height of the threaded column 201, the user can install the synchronization rod 601 607 on the synchronizing rod 601. The installation of the synchronizing rod 601 is completed. Due to the restriction of the synchronizing rod 601, the support seat 202 will maintain its initial orientation while changing its height, ensuring support for the pipeline after the adjustment is completed. Due to the thermal expansion and contraction of the pipeline,The length of the pipe will change slightly with temperature changes. Directly fixing the pipe to the support bracket may reduce its lifespan over long-term use. A first fixing sleeve 701 and a second fixing sleeve 702 are provided on the support base 202 for fixing the pipe. The bottom side of the first fixing sleeve 701 is provided with a connecting block 703. The connecting block 703 slides within the connecting groove 704 in the support base 202 via a pulley 705 on the bottom side. The setting of the connecting groove 704 allows a certain amount of lateral movement of the pipe when it is fixed, effectively reducing the impact of temperature and improving the support effect.
