Description

Technical Field

[0001] This utility model relates to the field of boiler pipe thermal expansion adjustment support technology, and in particular to a boiler pipe thermal expansion adjustment support device. Background Technology

[0002] During boiler pipeline operation, the deformation caused by thermal expansion and contraction is a key factor affecting the safety and stability of the equipment. This device mainly achieves flexible support and adjustment of the pipeline through the design of a mechanical structure. It uses high-strength steel as the main frame and connects the pipeline to the fixed base through support rods. The support rods are equipped with a spring buffer mechanism that can automatically extend when the pipeline expands thermally and automatically contract when it contracts, thereby effectively relieving the stress caused by temperature changes in the pipeline. Therefore, developing a more accurate and convenient support device has become an important direction for technological improvement.

[0003] In the existing technology, the support device for regulating thermal expansion of boiler pipes usually adopts a fixed structure, which has high overall stability, is firmly and reliably installed, has a simple structure, low cost, can support the pipe and relieve thermal expansion stress, and is very convenient to use. It can be applied to many long-term scenarios. However, in actual use, the support claw and the support frame are fixedly connected, and cannot be replaced separately after wear. The replacement is very inconvenient and the operation is too cumbersome.

[0004] However, existing boiler pipe thermal expansion regulating support devices still have certain problems in practical applications. On the one hand, the support claws are prone to wear when in contact with the pipe, and traditional structures are all fixed, making it impossible to replace the support claws individually, which affects the convenience of operation and the cost of use. On the other hand, the compression angle cannot be adjusted. Therefore, a boiler pipe thermal expansion regulating support device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a boiler pipe thermal expansion adjustment support device, which aims to improve the problem of the inability to replace the support soft claw in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a boiler pipe thermal expansion adjustment support device, comprising a support soft claw, characterized in that: a locking column is fixedly connected to the bottom of the support soft claw, a quick-change component is provided at the bottom of the locking column, a compression column is provided at the bottom of the support soft claw, and a rotary compression component is provided at the top of the compression column;

[0007] The quick-change assembly includes a buckle, the top of which is fixedly connected to the bottom of the buckle post, and a rotating post slidably connected to the bottom of the buckle post. The top of the rotating post slidably has an inner groove, and a pulling post is slidably connected inside the rotating post slidably. A sliding block is fixedly connected to one end of the pulling post, and a spring slidably fitted on the outer wall of the pulling post. One end of the spring slidably is fixedly connected to one side of the sliding block, and the other end of the spring slidably is fixedly connected to the inner wall of the rotating post slidably.

[0008] As a further description of the above technical solution:

[0009] The rotary compression assembly includes a rotary ball, the top of which is rolledly connected to the bottom of the rotary column two, and the bottom of which is rolledly connected to the rotary column one.

[0010] As a further description of the above technical solution:

[0011] A connecting column two is fixedly connected to the bottom of the rotating column one, and a cover plate is fixedly connected to the bottom of the connecting column two.

[0012] As a further description of the above technical solution:

[0013] The compression column is slidably connected to the outer wall of the connecting column. A spring is sleeved on the outer wall of the connecting column. One end of the spring is fixedly connected to the bottom of the cover plate, and the other end of the spring is fixedly connected to the compression column.

[0014] As a further description of the above technical solution:

[0015] The compression column has an inner groove, and a base is fixedly connected to the top of the compression column.

[0016] As a further description of the above technical solution:

[0017] The base has an inner groove three, and a fixing frame is fixedly connected to the top of the base.

[0018] As a further description of the above technical solution:

[0019] A sliding column is fixedly connected to the top of the fixed frame, and the sliding column is slidably connected to the outer wall of the second connecting column.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, when the pulling column is first pulled, the pulling column causes the sliding block to move outward, disengaging the sliding block from its slot. The buckle is then pulled outward to remove the supporting soft claw. Next, the buckle at the bottom of the new supporting soft claw is pushed into the inner groove. The sliding block has an inclined structure; when the buckle is pushed in, it compresses the sliding block as it slides past one side, compressing the spring. A slot is provided on the sliding block; when the buckle is fully pushed in, the spring pushes the sliding block into the slot, fixing the rotating column and the locking column together. This achieves the effect of replacing the supporting soft claw, solving the problem of the boiler pipe thermal expansion regulating support device being unable to replace the supporting soft claw, and improving the convenience of the boiler pipe thermal expansion regulating support device.

[0022] In this invention, the boiler tube first expands due to heat, compressing the supporting soft claw downwards. Under the action of the rotating ball, the rotating column and the locking column will adaptively adjust to the most suitable angle for better support. Under the action of the sliding column, it will not be affected by the angle adjustment of the rotating ball, achieving an adaptive effect, reducing the squeezing force on the boiler tube, solving the problem that the support rod of the boiler pipe thermal expansion adjustment support device cannot be adaptively adjusted, and improving the accuracy of the boiler pipe thermal expansion adjustment support device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-4 The present invention provides an embodiment of a boiler pipe thermal expansion adjustment support device, including a support soft claw 13, which is elastic and can better support the boiler pipe and prevent deformation caused by the expansion and compression of the boiler pipe. The bottom of the support soft claw 13 is fixedly connected to a locking post 12 to stabilize the support soft claw 13. The bottom of the locking post 12 is provided with a quick-change component. The bottom of the support soft claw 13 is provided with a compression post 2, and the top of the compression post 2 is provided with a rotary compression component.

[0032] The quick-change assembly includes a buckle 19 with an inner groove into which a sliding block 18 can slide to connect to the support claw 13. The top of the buckle 19 is fixedly connected to the bottom of the locking post 12, and a rotating post 11 is slidably connected to the bottom of the buckle 19 for stable support of the locking post 12. The top of the rotating post 11 has an inner groove 15 into which the buckle 19 slides. The inner groove 15 is infinitely movable, allowing the buckle 19 to disengage. A pulling post 16 is slidably connected inside the rotating post 11 for connecting the sliding block 18. The sliding block 18 can be pulled out from the slot inside the buckle 19. One end of the pulling column 16 is fixedly connected to the sliding block 18, which is used to fix the buckle 19 in the inner groove 2, thereby fixing the soft claw 13 on the top of the rotating column 2 11. The outer wall of the pulling column 16 is fitted with a spring 2 17. One end of the spring 2 17 is fixedly connected to one side of the sliding block 18, and the other end of the spring 2 17 is fixedly connected to the inner wall of the rotating column 2 11. This can better compress and reset the sliding block 18, preventing the plug from getting stuck and unable to be replaced during the process.

[0033] Reference Figure 5The rotary compression assembly includes a rotating ball 10, which is rolled to the bottom of a rotating column 11 to achieve rotational movement and adaptive angle adjustment. The top of the rotating ball 10 is rolled to the bottom of the rotating column 11, and a rotating column 9 is rolled to the bottom of the rotating ball 10 to provide support and a rotation path for the rotating ball 10, ensuring smooth rotation. A connecting column 6 is fixedly connected to the bottom of the rotating column 9, serving as an intermediate support for the structure and connecting the rotating part and the bottom structure. A cover plate 5 is fixedly connected to the bottom of the connecting column 6, which serves to seal and protect the internal structure and may also participate in force transmission during the compression process. The compression column 2 is slidably connected to the outer wall of the connecting column 3, and slides within the connecting column 3 to achieve compression and release functions. A spring 4 is sleeved on the outer wall of the connecting column 3 to provide necessary support and guidance for the compression column 2. Spring 4 is fixedly connected at one end to the bottom of cover plate 5 and at the other end to compression column 2. When spring 4 receives pressure, it compresses to compress the upper device downwards. During compression, it provides restoring force to ensure that the boiler pipe contraction lock compression column 2 can move upwards, thereby providing stable support. The compression column 2 has an inner groove 14 inside, and the connecting column 3 slides inside the inner groove 14 when compressed. The top of the compression column 2 is fixedly connected to a base 1, which provides stable support and an installation platform. The base 1 has an inner groove 20, which provides nail holes to fix the base 1 stably, preventing the entire support device from shifting due to boiler pipe expansion. The top of the base 1 is fixedly connected to a fixing frame 7, which is used to stably support the sliding column 8. The top of the fixing frame 7 is fixedly connected to the sliding column 8, which is used to limit the connecting column 6, allowing it to make stable vertical movement when the boiler pipe contracts and expands. The sliding column 8 is slidably connected to the outer wall of the connecting column 6.

[0034] Working principle: When using this boiler pipe thermal expansion adjustment support device, first pull the pulling column 16 outward. The pulling column 16 drives the sliding block 18 to move outward away from the inside of the buckle 19, thereby removing the buckle 12 connected to the top 11 of the rotating column 2. The buckle 12 and the support soft claw 13 are fixedly connected, thereby removing the support soft claw 13. Push the buckle 19 at the bottom of the replacement support soft claw 13 into the inner groove 2 15. The sliding block 18 has an inclined structure. When the buckle 19 is pushed in, the sliding block 18 will compress the spring 2 17 outward. When the buckle 19 reaches the designated position, the sliding block 18 is pushed into the inner groove of the buckle 19 by the left and right sides of the spring 2 17.

[0035] When the boiler pipe expands due to heat, the pipe presses down on the support claw 13. The rotating column 11 rotates to a suitable angle at the top of the rotating ball 10. The rotating column 11 drives the locking column 12 to adjust the angle. The locking column 12 drives the support claw 13 to adjust the angle. The support claw 13 presses down, thereby driving the rotating column 9 to press down. Under the limit of the sliding column 8, the cover plate 5 is pressed down vertically. The cover plate 5 presses down on the spring 4.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
