The present invention includes a variable spring support, a support protection mechanism, a buffer protection mechanism, a trigger mechanism and a warning mechanism, and the variable spring support includes a base, a cylindrical shell, a load spring, a displacement indicator plate and a load column. The present invention drives the transmission parts inside multiple sets of sleeves to rotate synchronously through the rotation of the transmission mechanism, so that the lifting parts inside the sleeves can be adjusted in height and position.

Description

Technical Field

[0001] The invention relates to the technical field of pipeline supports, and in particular to a variable spring support device for pipeline supports. Background Art

[0002] The variable spring hanger is a device used to support and hang pipes. It can adapt to load changes and displacements, thereby protecting the pipes from factors such as thermal expansion or contraction. It relies on the elastic deformation of the spring inside to absorb or release energy, thereby supporting the load and maintaining its stability. When the loaded pipe vibrates or moves due to various factors, the deformation of the spring will also change accordingly to maintain the balance of the load. Compared with rigid fixation, the movable support device increases the service life of the pipe.

[0003] The existing variable spring support hanger is composed of a shell, a spring, an indicator plate and a threaded support rod. The threaded support rod is threadedly installed on the indicator plate on the top of the spring. The indicator plate slides inside the shell. The height of the threaded support rod is adjusted according to the position of the supported pipeline. The pipeline is supported by the spring. However, during the long-term use of the bracket, due to external factors or production quality problems, the internal spring is broken or damaged, causing the pipeline at that location to suddenly lose support completely, causing the pipeline to be damaged, increasing the difficulty of repair work and slowing down the recovery efficiency of transportation work. If the staff fails to discover it in time, the loss caused is likely to be further expanded. Summary of the invention

[0004] In order to solve the above-mentioned problems, the present invention provides a variable spring support device for pipeline support to solve the problem that the spring inside the variable spring support bracket fails and loses its supporting function, which will cause the pipeline at that location to be unable to be transported.

[0020] The beneficial effects of the present invention are as follows:

[0021] The present invention drives the transmission parts inside the multiple sets of sleeves to rotate synchronously through the rotation of the transmission mechanism, so that the height position of the lifting parts inside the sleeve can be adjusted. According to the displacement change of different pipelines when in use, the lifting parts are adjusted to move below the extreme value of the pipeline displacement decrease. During the use of supporting the pipeline, if the load spring is broken or damaged due to external factors or quality problems, resulting in the device being unable to continue to support the pipeline, the support and protection mechanism can be used to support and protect the falling pipeline to avoid the situation where the pipeline completely loses support, prevents the pipeline from being damaged and increases the loss, and avoids hindering its up and down movement when the device is in normal use.

[0022] The present invention enables the cylindrical shell to move up and down along the top of the cylindrical shell through the rotation of the rotating mechanism, thereby driving the mobile ends of the multiple groups of buffer protection mechanisms at the bottom thereof to move up and down synchronously. According to the displacement change amount when different pipelines are used, the position of the mobile end of the buffer protection mechanism inside the buffer protection mechanism is adjusted, so that when the pipeline is in normal use, when the load column drives the displacement indicator plate to move down to the extreme value, the mobile end of the buffer protection mechanism fits with the top of the inner wall of the buffer protection mechanism. During the use of the supporting pipeline, if there is a problem with the load spring, the buffer protection mechanism can be used to buffer the displacement indicator plate. During the falling process of the displacement indicator plate, when the mobile end of the buffer protection mechanism fits with the top of the inner wall of the buffer protection mechanism and the buffer protection mechanism continues to move down, the mobile end of the buffer protection mechanism is pulled and deformed, thereby buffering the displacement indicator plate, avoiding the falling displacement indicator plate from being directly contacted with the top of the supporting protection mechanism without buffering, causing impact, causing secondary damage to the device, and increasing the possibility of pipeline damage.

[0023] The present invention uses a spring telescopic rod to move downward with the moving end of the buffer protection mechanism. If a problem occurs with the load spring, the moving end of the buffer protection mechanism continues to move downward and contacts the other end of the limiting special-shaped plate, pushing the limiting special-shaped plate to rotate, thereby releasing the limit of one end of the limiting special-shaped plate on the warning mechanism. The warning rod rotates from a vertical state to a horizontal state, and triggers a sound alarm, which emits an alarm sound to remind the staff. The position change of the warning rod indicates the specific device with the problem, so that the faulty device can be discovered as early as possible and repaired in time.

[0037] A transmission mechanism 2 is disposed on the top of the base 101 . A support and protection mechanism 3 is disposed on the top of the base 101 . The support and protection mechanisms 3 are provided in multiple groups and are arranged in a circular array on the top of the base 101 .

[0038] The supporting and protecting mechanism 3 includes a sleeve plate 301 , a transmission member and a lifting member. The sleeve plate 301 is fixedly mounted on the top of the base 101 , the transmission member is connected to the transmission mechanism 2 , and the lifting member is located below the displacement indicating plate 104 .

[0039] A rotating mechanism 4 is provided on the top of the cylindrical shell 102, and a buffer protection mechanism 5 is provided on the top of the displacement indicating plate 104. The moving end of the rotating mechanism 4 is fixedly connected to the moving end of the buffer protection mechanism 5. The buffer protection mechanisms 5 are provided in multiple groups and are arranged in a circular array on the top of the displacement indicating plate 104.

[0040] The trigger mechanism 6 includes a spring telescopic rod 601 and a limiting shaped plate 602. The spring telescopic rod 601 is fixedly installed at the bottom of the moving end of the buffer protection mechanism 5, and the limiting shaped plate 602 is rotatably installed inside the cylindrical shell 102. The limiting shaped plate 602 is L-shaped, and the middle part of the limiting shaped plate 602 is rotatably connected to the base 101. The end of the horizontal part of the limiting shaped plate 602 is located directly below the spring telescopic rod 601, and the end of the vertical part of the limiting shaped plate 602 is provided with an arc-shaped locking part bent outward.

[0042] The pipeline is supported by the variable spring support 1. The support of the pipeline by the device can adapt to its load change and displacement by relying on the deformable expansion and contraction of the load spring 103. The up and down movement of the load column 105 is kept stable by relying on the displacement indicator plate 104 and the guide column. The relative position of the load column 105 and the displacement indicator plate 104 can be adjusted by twisting the load column 105 to fit the bottom of the pipeline at different heights and support it. The transmission member in the support protection mechanism 3 is driven to rotate by rotating the transmission mechanism 2. The lifting member is driven to move up and down on the top of the sleeve plate 301 by the transmission member. The lifting member is controlled to move up and down on the top of the cylindrical shell 102 by rotating the rotating mechanism 4, so that the moving end of the buffer protection mechanism 5 connected thereto moves up and down accordingly. The spring expansion rod 601 contacts the limit shaped plate 602 as the buffer protection mechanism 5 moves downward, so that the limit shaped plate 602 rotates, and the limit on the warning rod is released, thereby triggering the alarm function of the sound alarm 704.

[0043] The variable spring support 1 also includes a top support 106 and a positioning block 107. The top support 106 is fixedly installed on the top of the load column 105. Through grooves are provided on the left and right sides of the cylindrical shell 102. Limit platforms slidably connected to the through grooves are provided on both sides of the displacement indicating plate 104. The positioning block 107 is slidably installed inside the through grooves of the cylindrical shell 102. Positioning blocks 107 are installed in the through grooves on the upper and lower sides of each limit platform to limit the displacement indicating plate 104 through the limit platform.

[0044] The positioning block 107 is fitted to the upper and lower sides of the displacement indicating plate 104 to limit the position of the displacement indicating plate 104 before the device is installed. The position of the displacement indicating plate 104 is consistent with the position of the load pipe when it is stationary. After the load pipe is supported, the positioning block 107 can be freely taken out.

[0045] The transmission mechanism 2 includes a dial 201, a transmission ring 202 and a driving wheel 203. The dial 201 is rotatably installed inside the base 101. One side of the dial 201 protrudes from the base 101 to facilitate the staff to rotate the dial 201. The transmission ring 202 is rotatably installed inside the base 101. The transmission ring 202 is coaxially arranged with the guide column and fixedly connected to the top of the transmission ring 202. The surface of the dial 201 is provided with teeth, and the transmission ring 202 is an outer gear ring. The dial 201 is meshed with the transmission ring 202. The driving wheel 203 is located on the upper side of the transmission ring 202 and meshed with it. The upper part of the driving wheel 203 extends into the interior of the sleeve 301 and meshes with the transmission member of the supporting protection mechanism 3. By turning the dial 201 to rotate inside the base 101, the dial 201 drives the transmission ring 202 to rotate, and the transmission ring 202 drives the driving wheel 203 to rotate on the top of the base 101, and the driving wheel 203 drives the multiple groups of transmission parts of the supporting protection mechanism 3 to rotate synchronously. In this embodiment, the driving wheel 203 is a bevel gear.

[0046] The transmission member includes a rotating rod 302 and a driven wheel 303. The rotating rod 302 is rotatably mounted inside the sleeve 301. A slot is provided at the top of the rotating rod 302. There are two groups of driven wheels 303. One group of driven wheels 303 is fixedly mounted at the bottom of the rotating rod 302, and the other group of driven wheels 303 is rotatably mounted on the inner wall of the sleeve 301. The driven wheels 303 are bevel gears, wherein the driven wheels 303 located on the inner wall of the sleeve 301 mesh with the driving wheel 203, and the two driven wheels 303 in the same group mesh with each other. Through the mutual meshing of the two groups of driven wheels 303 and the driving wheel 203, the rotation of the driving wheel 203 is transmitted through the driven wheels 303, thereby driving the rotating rod 302 to rotate.

[0047] The lifting member includes a threaded rod 304, a square column 305 and a support plate 306. The threaded rod 304 is installed on the upper part of the sleeve plate 301 and is threadedly connected to the top of the sleeve plate 301. The bottom end of the threaded rod 304 is fixedly installed with a square column 305. The rotating rod 302 is provided with a square hole that matches the square column 305. The lower end of the square column 305 can be slidably inserted into the square hole of the rotating rod 302. The square column 305 rotates synchronously with the rotating rod 302. The top end of the threaded rod 304 is rotatably installed with a support plate 306. The bottom of the support plate 306 is fixedly connected with a guide rod, and the guide rod is slidably plugged into the top of the sleeve plate 301.

[0048] The rotation of the rotating rod 302 is transmitted through the square column 305, driving the threaded rod 304 to rotate, and relying on the free sliding of the square column 305 on the top of the rotating rod 302, the threaded rod 304 threadedly installed on the top of the sleeve plate 301 can move up and down, driving the support plate 306 to adjust the height position.

[0049] The rotating mechanism 4 includes a rotating disk 401, a slide groove 402 and a slider 403. A connecting tube is provided at the bottom of the rotating disk 401. The connecting tube can be rotatably sleeved outside the load column 105. The lower part of the connecting tube extends into the top cover of the cylindrical shell 102 and is threadedly connected thereto. A slide groove 402 is provided at the bottom of the rotating disk 401. A slider 403 is slidably installed inside the slide groove 402. There are multiple groups of sliders 403, and the multiple groups of sliders 403 are arranged in a circular array inside the slide groove 402. A through hole is provided inside the rotating disk 401, and a handle is fixed around the rotating disk 401. The rotating disk 401 is moved up and down by pushing the rotating disk 401 to rotate. During the rotation process, the slider 403 slides inside the slide groove 402, so that the moving ends of the multiple groups of buffer protection mechanisms 5 connected to the slider 403 can move up and down synchronously.

[0050] Furthermore, the cross section of the slide groove 402 is T-shaped, and the slider 403 is a T-shaped block matched with the slide groove 402 .

[0051] The buffer protection mechanism 5 includes a push rod 501, a buffer spring 502, a card plate 503 and a sleeve 504. The push rod 501 is fixedly installed at the bottom of the moving end of the rotating mechanism 4. Furthermore, the top of the push rod 501 is fixedly connected to the corresponding slider 403. The lower end of the push rod 501 passes through the cylindrical shell 102 and can be slidably inserted into the cylindrical shell 102. The bottom of the push rod 501 is fixedly connected with a buffer spring 502, and the bottom of the buffer spring 502 is fixedly connected with a card plate 503. The sleeve 504 is fixedly installed at the top of the displacement indicating plate 104, and the buffer spring 502 is located inside the sleeve 504. The lower end of the push rod 501 and the card plate 503 can be slidably inserted into the sleeve 504. The push rod 501 is pushed by the rotating mechanism 4, passes through the top of the cylindrical shell 102, and drives the buffer spring 502 and the card plate 503 to move up and down inside the sleeve 504, thereby adjusting the height position of the card plate 503.

[0052] There are multiple groups of buffer protection mechanisms 5, which are arranged in a circular array on the top of the displacement indicating plate 104. A spring telescopic rod 601 is fixedly connected to the bottom of a group of clamping plates 503 close to the trigger mechanism 6. The clamping plates 503 are in contact with the top of the inner wall of the sleeve 504, and the clamping plates 503 are driven by the sleeve 504 to move downward, so that the spring telescopic rod 601 at the bottom of the clamping plates 503 moves downward accordingly.

[0053] The spring telescopic rod 601 is a telescopic rod with a built-in spring. The locking portion of the limiting shaped plate 602 fits against the top of the warning mechanism 7. Through the built-in spring of the spring telescopic rod 601, after the clamping plate 503 moves downward in the sleeve 504, the limiting shaped plate 602 is triggered by the spring telescopic rod 601. As the clamping plate 503 moves downward, the spring telescopic rod 601 can maintain the state of triggering the limiting shaped plate 602 without causing damage to the equipment. Compared with the buffer spring 502 that buffers the pipeline and supporting components, the deformation of the buffer spring 502 caused by the weight of the spring telescopic rod 601 itself is negligible. The spring telescopic rod 601 presses the other end of the limiting shaped plate 602 to cause the limiting shaped plate 602 to rotate, driving the locking portion of the limiting shaped plate 602 to separate from the warning mechanism 7.

[0054] The warning rod includes a rotating seat 701, an outer rotating plate 702 and an inner rotating plate 703. The rotating seat 701 is fixedly installed on the top of the base 101 and is located on the outside of the cylindrical shell 102. The outer rotating plate 702 is rotatably installed inside the rotating seat 701. The inner rotating plate 703 is rotatably installed inside the top of the outer rotating plate 702. Torsion springs are provided at the rotating part between the rotating seat 701 and the outer rotating plate 702, and at the rotating part between the outer rotating plate 702 and the inner rotating plate 703. The pressing trigger component of the sound alarm 704 is provided at the top thereof and is correspondingly provided with the outer rotating plate 702. The torsion spring connected to the outer rotating plate 702 causes it to rotate in a direction close to the sound alarm 704, while the torsion spring connected to the inner rotating plate 703 causes its lower end to move in a direction away from the sound alarm 704.

[0055] Through the torsion springs at the rotating ends of the outer rotating plate 702, after the limit of the warning mechanism 7 by the limit-shaped plate 602 is released, the outer rotating plate 702 and the inner rotating plate 703 both rotate toward the side of the sound alarm 704 until the outer rotating plate 702 presses the pressing trigger component of the sound alarm 704 and the inner rotating plate 703 rotates and extends.

[0056] In summary, when the present invention is used, the staff moves the device to the installation site, first fixes the base 101, and then rotates the load column 105 to make it rise according to the position of the pipeline to be supported, drives the top support 106 to fit with the bottom of the pipeline support seat, connects and fixes the two, removes the positioning block 107, and adjusts the height positions of the support plate 306 and the clamping plate 503 according to the extreme value of pipeline movement, turns the dial 201 to drive the transmission ring 202 to rotate, and the transmission ring 202 drives the driving wheel 203 to rotate, relying on the conduction of the driven wheel 303, so that The driving wheel 203 drives multiple groups of rotating rods 302 to rotate synchronously. After being transmitted by the square column 305, the threaded rod 304 drives the support plate 306 to move up and down on the top of the sleeve plate 301, adjusts and determines the position of the support plate 306, and then pushes the turntable 401 to rotate, so that the slider 403 slides inside the slide groove 402. The up and down movement of the turntable 401 drives multiple groups of push rods 501 connected to the slider 403 to move synchronously, and pushes the card plate 503 at the bottom end of the buffer spring 502 to move up and down inside the sleeve 504, and adjusts and determines the position of the card plate 503.

[0057] The device is normally used to elastically support the pipeline, relying on the load spring 103 to adapt to load changes and displacements. If the load spring 103 is broken or damaged due to external factors or quality problems, the pipeline loses support, and the displacement indicator plate 104 falls beyond the normal downward limit, driving the top of the inner wall of the sleeve 504 to contact the card plate 503, so that the buffer spring 502 is stretched and deformed, thereby buffering and protecting the downward movement of the displacement indicator plate 104 until the displacement indicator plate 104 continues to move downward to contact the top of the support plate 306, relying on the support plate 306 to support and protect it. At the same time, the sleeve 504 pulls the card plate 503 downward. , the spring telescopic rod 601 at the bottom of the card plate 503 is driven to move downward and contact one end of the limiting shaped plate 602, pressing to cause the limiting shaped plate 602 to rotate, and the other end of the limiting shaped plate 602 is separated from the warning mechanism 7, releasing the limit of the warning mechanism 7. At this time, the torsion springs at the rotating ends of the outer rotating plate 702 push the outer rotating plate 702 to rotate along the rotating seat 701, and the inner rotating plate 703 rotates along the outer rotating plate 702 until the outer rotating plate 702 presses the pressing trigger component of the sound alarm 704, and a sound is issued to remind the staff that the device has a fault. The inner rotating plate 703 rotates and extends to instruct the staff to find the specific faulty device and perform repair work in time.
