[0024] The technical scheme of the utility model will be described clearly and completely in combination with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] The utility model will be described in detail in combination with the drawings and specific embodiments. Figure 1 to the drawings Figure 3 and specific embodiments.

[0026] As Figures 1 to 3 shown, the utility model provides a device for preventing metal pipe subsidence, including metal bellows 1, process pipe 2 and adjusting mechanism 3, the adjusting mechanism 3 includes door type limiting frame 4, the door type limiting frame 4 side wall is set with the slot for the metal bellows 1 in and out, be provided with movable cushion block 5, fixed part 6 and elastic part 7 in the slot, the movable cushion block 5 is used to support metal bellows 1, the fixed part 6 is used to fix metal bellows 1, the elastic part 7 sets up at movable cushion block 5 end face, the elastic part 7 is used to adjust the height of metal bellows and slot.

[0027] In this embodiment, the design of the adjusting mechanism 3 adopts the form of a door-type limiting frame 4, which can provide the necessary support and positioning for the metal bellows 1. Special notches are opened on the side walls of the door-type limiting frame 4, which not only allow the metal bellows 1 to smoothly enter and exit, but also provide space for other components. Inside the notches are configured with three components: a movable cushion block 5, a fixed part 6, and an elastic part 7, which work together to effectively manage and protect the metal bellows 1. The movable cushion block 5, as the part directly in contact with the metal bellows 1, bears the role of supporting the pipe, which can slide along the notch as needed to adapt to different working conditions and always maintain good support for the pipe. The fixed part 6, through appropriate fastening methods, can firmly fix the pipe in the desired position, preventing unnecessary movement due to external forces or self-weight. The elastic part 7, located on the end face of the movable cushion block 5, can adjust the height of the metal bellows 1 relative to the notch when the external environment changes or the pipe itself deforms, thereby ensuring that the pipe is always in the best working state.

[0028] When the metal bellows 1 is placed in the notch of the door-type limiting frame 4, the movable cushion block 5 first provides a preliminary support platform. With further operation, the fixed part 6 will fix the pipe, and at this time, if there is a height difference or other factors causing uneven stress, the elastic part 7 will play a role by automatically adjusting to balance these influences. This mechanism not only effectively avoids permanent deformation or damage to the metal pipe due to long-term pressure, but also improves the overall reliability and service life of the system.

[0029] In this embodiment, the elastic part 7 is a compression spring, one end of which is connected to the inner wall of the notch, and the other end is connected to the end face of the movable cushion block 5.

[0030] In this embodiment, when the metal bellows 1 is placed in the notch of the door-type limiting frame 4, the compression spring can automatically adjust its length according to the actual position and weight of the pipe. If the pipe sinks or is subjected to additional load, the compression spring will compress accordingly to maintain the appropriate distance between the pipe and the notch; conversely, if the pipe rises or the load decreases, the compression spring will elongate to ensure that the pipe is always at the optimal working height. This helps to maintain the shape of the pipe and prevent permanent deformation due to long-term pressure.

[0031] In other embodiments, in industrial environments, pipeline systems often face vibrations and impacts from external environments or internal fluid flow. The compression spring can effectively absorb these energies and reduce the vibration transmitted to the metal bellows 1, thereby protecting the pipe and prolonging its service life.

[0032] The elastic force provided by the compression spring can ensure that the moving pad 5 supports the metal bellows 1 evenly and stably. Even if the external conditions change, such as material expansion or contraction caused by temperature fluctuations, the compression spring can adapt to these small changes through its own elastic changes, ensuring that the pipe always remains in a relatively fixed position.

[0033] In order to facilitate installation and subsequent maintenance, the design of the compression spring takes into account the ease of operation. It is directly connected between the inner wall of the door type limiting frame 4 slot and the moving pad 5, and the installation process is simple and fast, only need to fix the two ends of the spring. At the same time, if the compression spring needs to be replaced or adjusted, it only needs to loosen the corresponding fixing point, and it can be easily completed without disassembling the entire device, greatly improving work efficiency.

[0034] In this embodiment, the fixing member 6 includes a screw rod, one end of the screw rod penetrates the compression spring and is connected with the moving pad 5, and the other end of the screw rod penetrates and extends out of the door type limiting frame 4, and the end face of the door type limiting frame 4 is provided with a nut for threaded connection with the screw rod.

[0035] In this embodiment, one end of the screw rod penetrates the compression spring and is connected with the moving pad 5, ensuring that the screw rod not only can transmit the fixing force from the outside, but also can work with the compression spring to allow a certain displacement and elastic recovery when needed. Since the screw rod penetrates the compression spring, it actually plays a role in protecting the compression spring, preventing the spring from being twisted or damaged when subjected to excessive external force or uneven stress; the screw rod is directly connected with the moving pad 5, ensuring close contact between the two. This allows the moving pad 5 to better support the metal bellows 1 under the support of the screw rod, and by rotating the screw rod, the position of the moving pad 5 can be adjusted, and in turn the height of the metal bellows 1 can be fine-tuned, ensuring that it is always in the best working condition; the other end of the screw rod extends out of the door type limiting frame 4 and is connected with the nut on the end face of the frame through a thread, allowing the operator to directly tighten the nut from the outside without disassembling other components to tighten or loosen the metal bellows 1; the threaded connection between the screw rod and the nut provides a high-strength fixing effect, and at the same time, due to the presence of the thread, the fixing force can also be finely adjusted according to actual needs, ensuring that the metal bellows 1 will not be damaged due to being too tight, nor will it lose its proper support due to being too loose.

[0036] In this embodiment, both ends of the metal bellows are connected with the process pipe 2 through a welded interface.

[0037] In this embodiment, the welding interface can provide extremely high mechanical strength, ensuring that the connection between the metal bellows and the process pipe 2 will not loosen or separate due to external pressure, temperature changes, or vibrations. The welding process can achieve complete metal fusion, avoiding the leakage problems that may occur with traditional threaded connections or other mechanical connection methods, especially when transporting high-pressure or corrosive media, the sealing of the welding interface is particularly important.

[0038] In this embodiment, one side of the process pipe 2 is in a horizontal state, and the process pipe 2 is fixed to the top surface by a fastening U-shaped pipe clamp.

[0039] In this embodiment, the other side of the process pipe 2 is in a vertical state, and the process pipe 2 is connected with an adjusting pipe through a fastening U-shaped pipe clamp.

[0040] In this embodiment, for the process pipe 2 in a horizontal state: the process pipe 2 on this side is placed horizontally, usually at the top of the equipment or other locations where horizontal laying is required. It is firmly fixed to the top surface by a fastening U-shaped pipe clamp. The U-shaped pipe clamp is a common pipe fixing piece 6, which consists of a U-shaped metal clamp with bolts and nuts at both ends, allowing the pipe to be clamped and fixed in place conveniently.

[0041] For the process pipe 2 in a vertical state: the process pipe 2 on this side is installed vertically upwards, suitable for situations where the medium needs to be transported vertically or connected with other vertical pipe systems. Similarly, a fastening U-shaped pipe clamp is used, but here the U-shaped pipe clamp is not only used for fixation, but also connects the process pipe 2 in a vertical state with the adjusting pipe. The presence of the adjusting pipe provides additional flexibility to the entire system, allowing the height or angle of the pipe to be adjusted according to actual conditions; by using the adjusting pipe in combination with the U-shaped pipe clamp, the position of the process pipe 2 in a vertical state can be easily adjusted without changing the original pipe layout. For example, when encountering ground subsidence, thermal expansion and contraction of pipes caused by temperature changes, etc., these changes can be compensated by adjusting the adjusting pipe appropriately, ensuring the normal operation of the pipe system. The U-shaped pipe clamp can tightly fit the pipe surface, and through the tightening force of the bolts and nuts, the process pipe 2 is firmly fixed in the required position, preventing it from moving due to external factors.

[0042] In this embodiment, the adjusting pipe is provided with several flanges.

[0043] In this embodiment, the moving pad 5 has a U-shaped cross-section.

[0044] The utility model is further described with the help of specific embodiments above by the staff above, but should understand, here specific description, should not be understood as the limitation of the essence and scope of the utility model, various modifications of above-mentioned embodiment made by the ordinary skilled in the art after reading the specification all belong to the range of the utility model.
