Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and in particular to a high-temperature resistant constant force spring support and hanger integrated device for pipe racks. Background Technology

[0002] Spring supports are designed based on the principle of torque balance. Within a specified load displacement range, the load torque and spring torque remain balanced. Therefore, when pipes and equipment supported by constant hangers experience displacement, a constant supporting force can be obtained, without introducing additional stress to the pipes and equipment.

[0003] A search revealed a constant force spring hanger with publication number CN211315489U. The hanger features a support frame fixed to the top inner side of the outer casing. A first support column runs through the middle of the support frame, with a limit block fixed to the top of the first support column. The bottom of the limit block is connected to the outside of the support frame via a first spring. Second leaf springs are provided on both sides of the U-shaped frame, and a second support column inserted into the U-shaped frame is fixed to the outside of the cylinder. This hanger uses the first spring, second spring, first leaf spring, and second leaf spring to jointly support the hanger rod, enabling the hanger rod to provide constant force support to the pipeline. The second support column compresses the second leaf spring, allowing the second leaf spring to provide elastic support to the second support column. The second spring supports the first leaf spring, enhancing its elasticity and effectively buffering the impact force on the pipeline during hoisting, preventing damage due to impact.

[0004] When in use, the device in the disclosed patent has difficulty in providing a relatively constant support force throughout the entire stroke. It may be too stiff under light loads, and the buffer stroke may be insufficient or the support force may increase sharply under heavy loads. In addition, the impact force on the pipeline is large when the spring quickly returns to its original position, which affects the buffering effect on the pipeline. Utility Model Content

[0005] In response to the technical problems in existing patents, such as the difficulty in providing a relatively constant support force throughout the entire stroke of the device during use, the potential for excessive stiffness under light loads, insufficient buffer stroke or a sharp increase in support force under heavy loads, and the large impact force on the pipeline when the spring quickly returns to its original position, which affects the buffering effect on the pipeline, this utility model provides a high-temperature resistant constant force spring support and pipe rack integrated device.

[0006] The technical solution adopted by this utility model is: a high-temperature resistant constant force spring support and pipe rack integrated device, including: support and pipe rack, wherein the support and pipe rack includes a box, a first buffer mechanism and a second buffer mechanism disposed in the box, and a limiting mechanism disposed on the box;

[0007] The first buffer mechanism includes a plurality of first buffer plates that are elastically slidably fitted inside the housing, a plurality of first high-temperature resistant springs fixed to the bottom of the first buffer plates, and a plurality of transmission rods that are slidably fitted inside the housing. The transmission rods are fixed to the first buffer plates located at the upper end of the first buffer mechanism, and one end of the transmission rods extends through the remaining first buffer plates and out of the housing. The spring force of the first high-temperature resistant springs at the bottom of the plurality of first buffer plates gradually decreases along the height direction of the first buffer mechanism.

[0008] The second buffer mechanism includes a second buffer plate that is elastically slidably fitted on the first buffer mechanism, the limiting mechanism is corresponding to the second buffer plate, and the tube frame is fixed on one end of the transmission rod that extends out of the housing.

[0009] Furthermore, in the first buffer mechanism, two adjacent first buffer plates are connected by a first high-temperature resistant spring, and the first high-temperature resistant spring located at the bottom end of the first buffer mechanism is fixed to the bottom surface of the inner wall of the box.

[0010] Furthermore, the second buffer mechanism also includes a second high-temperature resistant spring fixed to the bottom end of the second buffer plate. One end of the second high-temperature resistant spring is fixed to the first buffer plate located at the upper end of the first buffer mechanism, and the second buffer plate is slidably fitted into the housing.

[0011] Furthermore, the first buffer plate has multiple first damping holes evenly distributed on its upper side, the second buffer plate has multiple second damping holes evenly distributed on its upper side, and the upper side of the housing is provided with two U-shaped mounting brackets.

[0012] Furthermore, the limiting mechanism includes an electric push rod fixed to the bottom surface of the inner wall of the box and a limiting plate disposed at the bottom end of the electric push rod.

[0013] Furthermore, the tube frame includes a guide bar fixed to the bottom surface of the plurality of transmission rods, a T-shaped guide groove at the bottom end of the guide bar, two tube clamps slidably fitted in the T-shaped guide groove, a servo motor on one side of the guide bar, and a bidirectional threaded rod on the output shaft of the servo motor. The threads at both ends of the bidirectional threaded rod are opposite in direction, and the two ends of the bidirectional threaded rod are respectively threaded into the two tube clamps. Bearing seats are provided at both ends of the T-shaped guide groove, and bearings are provided in the bearing seats. Smooth surfaces are provided on the outer sides of the ends of the bidirectional threaded rod, and the two ends of the bidirectional threaded rod are respectively fixed in the two bearings.

[0014] The beneficial effects of this utility model are:

[0015] By setting the first buffer mechanism with the spring force of the first high temperature resistant springs at the bottom of the multiple first buffer plates along the height direction gradually decreasing, it is convenient to buffer the impact force of the pipe through the first high temperature resistant springs with different spring forces, and reduce the impact of the first high temperature resistant springs being too hard or too soft on the pipe buffering effect.

[0016] By setting the first damping hole and the second damping hole, when the pipeline is quickly lifted and transported by the support, the first buffer plate compresses the air in the box through the first damping hole to improve the buffering effect on the pipeline, and the second buffer plate compresses the air in the box through the second damping hole to improve the buffering effect on the pipeline; when the first high-temperature spring returns to its original position, the first damping hole reduces the upward speed of the first buffer plate, reduces the return speed of the first high-temperature spring, and reduces the impact force of the first high-temperature spring on the pipeline.

[0017] By setting a limiting plate, when the second buffer plate contacts the limiting plate, the limiting plate blocks the second buffer plate from moving upward, causing the second high-temperature resistant spring to compress. This facilitates further reduction of the upward speed of the first buffer plate, reduces the reset speed of the first high-temperature resistant spring, and reduces the impact force of the first high-temperature resistant spring on the pipeline.

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0027] To address the problems existing in the background art, this application proposes the following technical solution:

[0028] A high-temperature resistant constant force spring support and pipe rack integrated device includes: support 1 and pipe rack 2. The support 1 includes a housing 101, a first buffer mechanism 102 and a second buffer mechanism 103 disposed in the housing 101, and a limiting mechanism 104 disposed on the housing 101.

[0029] The first buffer mechanism 102 includes a plurality of first buffer plates 1021 elastically slidingly fitted inside the housing 101, a plurality of first high-temperature resistant springs 1022 fixed at the bottom of the first buffer plates 1021, and a plurality of transmission rods 1023 slidingly fitted inside the housing 101. The transmission rods 1023 are fixed to the first buffer plates 1021 located at the upper end of the first buffer mechanism 102. One end of the transmission rod 1023 passes through the other first buffer plates 1021 and extends out of the housing 101. The spring force of the first high-temperature resistant springs 1022 at the bottom of the plurality of first buffer plates 1021 gradually decreases along the height direction of the first buffer mechanism 102.

[0030] The second buffer mechanism 103 includes a second buffer plate 1031 that is elastically slidably fitted on the first buffer mechanism 102, a limiting mechanism 104 that corresponds to the second buffer plate 1031, and a tube frame 2 that is fixed on one end of the transmission rod 1023 that extends out of the housing 101.

[0031] Furthermore, two adjacent first buffer plates 1021 in the first buffer mechanism 102 are connected by a first high-temperature resistant spring 1022, and the first high-temperature resistant spring 1022 located at the bottom of the first buffer mechanism 102 is fixed to the bottom surface of the inner wall of the box 101.

[0032] Furthermore, the second buffer mechanism 103 also includes a second high-temperature resistant spring 1032 fixed at the bottom of the second buffer plate 1031. One end of the second high-temperature resistant spring 1032 is fixed on the first buffer plate 1021 located at the upper end of the first buffer mechanism 102, and the second buffer plate 1031 is slidably fitted inside the housing 101.

[0033] Furthermore, the upper side of the first buffer plate 1021 is evenly distributed with a plurality of first damping holes 1024, the upper side of the second buffer plate 1031 is evenly distributed with a plurality of second damping holes 1033, and the upper side of the housing 101 is provided with two U-shaped mounting brackets 105, which facilitates the fixing of the housing 101 to an external object through the U-shaped mounting brackets 105.

[0034] Furthermore, the limiting mechanism 104 includes an electric push rod 1041 fixed to the bottom surface of the inner wall of the housing 101 and a limiting plate 1042 located at the bottom end of the electric push rod 1041.

[0035] Furthermore, the tube frame 2 includes a guide bar 201 fixed to the bottom surface of multiple transmission rods 1023, a T-shaped guide groove 202 at the bottom end of the guide bar 201, two tube clamps 203 slidingly fitted in the T-shaped guide groove 202, a servo motor 204 on one side of the guide bar 201, and a bidirectional threaded rod 205 on the output shaft of the servo motor 204. The threads at both ends of the bidirectional threaded rod 205 are opposite in direction, and both ends of the bidirectional threaded rod 205 are threadedly fitted with the two tube clamps 203 respectively. Bearing seats are provided at both ends of the T-shaped guide groove 202, and bearings are provided in the bearing seats. Smooth surfaces are provided on the outer sides of the ends of both ends of the bidirectional threaded rod 205, and both ends of the bidirectional threaded rod 205 are fixed in the two bearings respectively.

[0036] Working principle: The servo motor 204 drives the bidirectional threaded rod 205 to move the two pipe clamps 203 towards each other, clamping the pipe. Then, when the pipe is lifted by the support bracket 1, it is slowly lifted off the pipe support seat. The pipe support 2, under the weight of the pipe, pulls the first buffer plate 1021 through the transmission rod 1023, compressing the first high-temperature resistant spring 1022. The second high-temperature resistant spring 1032 pulls the second buffer plate 1031 to slide. Then, the electric push rod 1041 drives the limit plate 1042 to engage with the second buffer plate 1031. At this point, the first buffer... The tension force on mechanism 102 is equal to the weight of the pipeline. When the pipeline is quickly lifted and transported by the support 1, the upward impact force on the pipeline continues to pull the first buffer plate 1021 through the pipe support 2 and the transmission rod 1023, compressing the first high-temperature resistant spring 1022. The second high-temperature resistant spring 1032 then pulls the second buffer plate 1031 to slide. When the first buffer plate 1021 slides, the air inside the housing 101 is compressed by the first buffer plate 1021 and passes through the first damping hole 1024, thereby improving the buffering effect on the pipeline. The buffer plate 1031 compresses the air inside the housing 101 and passes it through the second damping hole 1033, thereby improving the buffering effect on the pipeline. When the first high-temperature resistant spring 1022 returns to its original position, it simultaneously passes through the first damping hole 1024, reducing the upward movement speed of the first buffer plate 1021, reducing the return speed of the first high-temperature resistant spring 1022, and reducing the impact force of the first high-temperature resistant spring 1022 on the pipeline. When the second buffer plate 1031 contacts the limiting plate 1042, the limiting plate 1042 blocks the upward movement of the second buffer plate 1031, causing the first... The compression of the two high-temperature resistant springs 1032 facilitates further reduction of the upward movement speed of the first buffer plate 1021, reduces the reset speed of the first high-temperature resistant spring 1022, and reduces the impact force of the first high-temperature resistant spring 1022 on the pipeline during reset. By setting the first buffer mechanism 102 to gradually reduce the spring force of the first high-temperature resistant springs 1022 at the bottom of the multiple first buffer plates 1021 along the height direction, it is convenient to buffer the impact force on the pipeline through the first high-temperature resistant springs 1022 with different spring forces, and reduce the impact of the first high-temperature resistant spring 1022 being too hard or too soft on the pipeline.
