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. Under the permitted load displacement, the load moment and spring moment are always balanced. For pipes and equipment supported by constant force spring supports and hangers, constant support force can be provided when displacement occurs, so no additional stress is brought to the pipe equipment. Constant force spring supports and hangers are generally used in places where displacement stress needs to be reduced, such as the boiler body of a power station, the suspended parts of steam, water, smoke, air ducts and burners of a power plant, and places where such support is needed in the petroleum and chemical industries.

[0003] The constant force spring support and hanger supports the pipeline through the spring set inside. The pressure carried by different pipe supports and hangers is also different. Since the spring inside the support and hanger is often unable to be replaced, it is often necessary to select supports and hangers of different specifications. In addition, the screw rod at the top of the support and 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. On the other hand, the pipeline will also change in length due to the influence of thermal expansion and contraction, and it is difficult to eliminate this effect with existing supports and hangers.

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 is convenient for maintaining the position of the lifting seat 203 and then 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 seat 203 down. At this time, the lifting slider 211 conflicts with the blocking rod 207 on the bottom side, so that the lifting seat 203 is maintained in the initial position, which is convenient for adjusting the supporting effect of the support and hanger.

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 mounted on the side cover 301. The side cover 301 is fixed to the snap-fit ​​groove 305 on the housing 1 through the snap-fit ​​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 be freely raised and lowered in height. When the side cover 301 is opened, the blocking rods 207 on both sides are pushed by the second spring 212.

When the side cover plate 301 is in a closed state, the inner side of the side cover plate 301 will push the blocking rod 207, so that the inclined groove 209 on the blocking rod 207 is connected with the guide groove 210. At this time, the lifting seat 203 can be freely raised and lowered in height, and when the side cover 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 pipelines, the user can choose different support springs 303 for support. The support spring 303 can be fixed by the expansion rod 308 on the bearing 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 bearing 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 pipeline. For different types 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 bearing plate 307 conflicts with the top of the lifting stud 402. The user can rotate the rocker 401 located on the side of the housing 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 bearing plate 307 can be adjusted. After the side cover 301 is closed, the lifting seat 203 can slide freely, and 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 bearing 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 pipeline, which is more flexible to use and has sufficient buffer distance when facing the need for large displacement support. After completing the fixing of the side cover plate 301 and the rough adjustment of the extension height of the threaded column 201, in order to accurately control the support height, the user can turn the hand wheel 507 located on the side of the support seat 202. The rotation of the hand wheel 507 will eventually 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 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. By rotating the adjusting rod 501, 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 On the first side block 603 and the second side block 604 set on the same side, the side of the synchronization rod 601 is provided with a slot 602. During installation, the support seat 202 and the housing 1 are first rotated to align, and then the first side block 603 is slid into the inside of the synchronization rod 601, and then the position of the synchronization rod 601 is adjusted by sliding, so that the second side block 604 slides into the inner side of the synchronization rod 601 from the slot 602, and finally the synchronization rod 601 is slid so that the end of the positioning column 605 at the end of the second side block 604 is engaged with the positioning groove 607 on the synchronization rod 601 to complete the installation of the synchronization rod 601. Through the restriction of the synchronization rod 601, the support seat 202 will maintain the initial orientation while the height changes, so as to ensure the support of the pipeline after the adjustment is completed. 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 the service life under long-term use. The first fixing sleeve 701 and the second fixing sleeve 702 are provided on the support seat 202 for fixing the pipeline, and the bottom side of the first fixing sleeve 701 is provided with a connecting block 703. The connecting block 703 slides in the connecting groove 704 in the support seat 202 through the pulley 705 on the bottom side. The setting of the connecting groove 704 allows the pipeline to have a certain lateral movement space when fixed, effectively reducing the impact of temperature and improving the support effect.
