Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of boiler pipeline support, specifically relates to a buffer shock support for boiler pipeline. BACKGROUND

[0002] In the field of industrial boiler pipeline support, the stability and adaptability of the support are the key to ensuring the safe operation of the system. The existing patent CN222669156U discloses a buffer type support for boiler pipeline, which realizes height adjustment through a screw rod assembly and uses elastic pads for shock absorption and buffering. However, this scheme still has significant technical limitations: first, the shock absorption structure only relies on fixedly installed elastic pads, and there is no dynamic self-adaptive support for the rotating part during height adjustment. When the support screw drives the pipeline support seat to rise and fall, the compression amount of the elastic pad cannot be adjusted synchronously with the position change of the rotating disc, resulting in uneven shock absorption performance at different heights, especially in high-temperature working conditions, the elastic material is prone to aging and failure; second, the pipeline clamping mechanism adopts a single-sided sliding adjustment method, and a single screw drives the clamping plate to move. The clamping symmetry for different diameter pipelines is insufficient, and there is no reliable locking structure, which is prone to clamping plate displacement during pipeline vibration, posing a safety hazard.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Please refer to Figures 1-4 The utility model provides a kind of technical solutions: a kind of buffer shock support for boiler pipeline, comprising:

[0026] Pipeline support block 1, it provides stable installation and bearing base for entire support system. Its solid material and reasonable shape design can bear the gravity and dynamic load from boiler pipeline and other structural members, ensure that support does not displace or deform under complex working conditions, and the end of pipeline support block 1 is provided with pipeline support seat 3 adjusted according to the height of suspended support of boiler pipeline by threaded lifting support screw 2, and support screw 2 efficiently converts the rotary motion of rotating disc 6 into linear lifting motion, to realize the accurate adjustment of the height of pipeline support seat 3. Its high-strength material ensures that it will not bend or break when bearing the force of pipeline gravity and adjustment process, and pipeline support seat 3 provides installation base for double-thread rotating rod 12, moving block 13, pipeline support clamping plate 4 and other components. Its reasonable size and structure design ensure the stability when adjusting the spacing of pipeline support clamping plate 4, and the reliability when clamping different diameter pipelines, and pipeline support clamping plate 4 is adjusted and slid on the upper end surface of pipeline support seat 3 for adjusting and clamping support according to different diameter filter pipelines, and is fixedly connected with moving block 13 through the bottom stabilizing support block 15 and moves with moving block 13. Two pipeline support clamping plates 4 are symmetrically distributed below the pipeline, and jointly realize clamping and supporting the pipeline.

[0027] The top end of the supporting screw rod 2 is provided with a supporting shaft seat 5 for supporting the height adjustment of the pipeline supporting seat 3 without following the rotation when the supporting screw rod 2 rotates and lifts. The unique structural design effectively solves the problem that the pipeline supporting seat 3 rotates when the supporting screw rod 2 rotates, ensures that the pipeline supporting seat 3 can move up and down stably and vertically, accurately adapts to the suspended support requirements of the boiler pipeline at different heights, greatly improves the precision and stability of the height adjustment, and is provided with a rotating disc 6 for rotating and lifting. By rotating it, the rotating and lifting of the supporting screw rod 2 can be easily realized. The strip-shaped supporting blocks 18 uniformly distributed on the upper end surface side reduce the friction during rotation, save manpower, and uniformly transmit the supporting force to the pipeline supporting seat 3, avoiding deformation or damage of the supporting seat due to uneven local stress, and improving the stability of the entire supporting structure. The pipeline supporting block 1 is provided with a damper 8 in the installation cavity 7 on the inner side of the end portion for self-adapting and following extension and jacking support during the lifting of the rotating disc 6. The length of the damper 8 can be adjusted in real time according to the position change of the rotating disc 6, effectively buffers the displacement of the rotating disc 6, converts part of the vibration energy into other forms of energy and consumes it, and greatly reduces the influence of vibration on the boiler pipeline. Compared with the traditional fixed elastic pad damping method, uniform damping effect can be continuously and stably provided in the whole range of height adjustment of the support, especially in complex working conditions such as high temperature and high pressure, avoiding the problem of damping failure caused by aging of elastic materials.

[0028] The damper 8 is installed in the installation cavity 7 uniformly arranged on the side of the end portion of the pipeline supporting block 1. Its unique structural design enables it to have self-adapting extension and contraction capability. When the rotating disc 6 is displaced due to pipeline vibration or height adjustment, the vibration jacking block 9 first senses the displacement change and transmits it to the piston or piston rod inside the damper 8. The damper 8 usually adopts a piston structure, and the piston moves in the cylinder filled with damping medium. When the piston is subjected to the displacement force from the rotating disc 6, it will move in the cylinder. Since the damping medium has a certain viscosity, the piston will be subjected to the resistance of the damping medium during movement. The resistance is related to the speed of the piston. The faster the speed, the greater the resistance. In this way, the damper 8 can automatically adjust its extension length and buffer force according to the speed and amplitude of the displacement of the rotating disc 6, and realize precise buffering of the displacement of the rotating disc 6.

[0029] The core principle of the operation of the damper 8 is to convert vibration energy into other forms of energy and consume it. When the piston of the damper 8 moves in the cylinder, the damping medium will rub with the piston and the inner wall of the cylinder, and at the same time, viscous shear deformation will occur inside the damping medium. These friction and deformation processes will convert the mechanical energy of vibration into heat energy. For example, when the pipeline vibrates at a high frequency, the piston reciprocates rapidly, the friction between the damping medium and the piston increases, a large amount of mechanical energy is rapidly converted into heat energy, and the heat energy is dissipated to the surrounding environment through the shell of the damper 8. In addition, part of the energy may also be consumed in the form of sound energy and other forms, but the main form of energy conversion is heat energy. Through this continuous energy conversion and consumption process, the damper 8 effectively weakens the influence of vibration on the support and pipeline system, ensuring the stable operation of the system.

[0030] The mounting cavities 7 are uniformly arranged around the side of the end of the pipeline support block 1, and the dampers 8 are mounted in the mounting cavities 7. The top end of each damper 8 is provided with a damping top block 9 abutting the lower end surface of the rotating disc 6, which serves as a contact component between the damper 8 and the rotating disc 6, and can uniformly transmit the buffering force of the damper 8 to the rotating disc 6, while reducing the wear between the damper 8 and the rotating disc 6, prolonging the service life of the damper 8, and improving the stability of the buffering and damping effect. An internally threaded groove 10 is formed in the center of the end of the pipeline support block 1, and one end of the support screw 2 is threadedly arranged in the internally threaded groove 10 to rotate and lift to adjust the lifting support of the pipeline support seat 3.

[0031] A sliding groove 11 is formed in the center of the end of the pipeline support seat 3, and a double-headed threaded rotating rod 12 with threads at both ends is rotatably arranged in the sliding groove 11. By rotating the auxiliary rotating disc 14 to rotate the double-headed threaded rotating rod 12, the two end moving blocks 13 can be synchronously and oppositely moved, efficiently and accurately adjusting the distance between the pipeline support clamping plates 4 to adapt to boiler pipelines of different diameters. Compared with the single-sided adjustment method, the adjustment efficiency and clamping symmetry are greatly improved. The two ends of the double-headed threaded rotating rod 12 are both threadedly sleeved with the moving blocks 13, which serve as intermediate components connecting the double-headed threaded rotating rod 12 and the pipeline support clamping plates 4, accurately converting the rotation of the double-headed threaded rotating rod 12 into linear movement to stably drive the pipeline support clamping plates 4 to approach or move away, realizing clamping or loosening of the pipeline, and ensuring the stability and accuracy of the pipeline clamping process. One end of the double-headed threaded rotating rod 12 is movably penetrated to one side outside the pipeline support seat 3 and is provided with the auxiliary rotating disc 14.

[0032] The bottom of each pipe supporting clamping plate 4 is provided with a stable supporting block 15, which enhances the stability of the connection between the pipe supporting clamping plate 4 and the moving block 13, keeps the pipe supporting clamping plate 4 stable during the movement and clamping of the pipe, avoids shaking or displacement, improves the reliability of the whole pipe clamping system, and transmits the movement of the moving block 13 to the pipe supporting clamping plate 4; the front and rear surfaces are provided with adjusting lock plates 16, which are matched with the threaded lock holes 19 on the surface of the pipe supporting seat 3 to realize position locking, the front and rear surfaces of the stable supporting block 15 are provided with the adjusting lock plates 16, the threaded lock rods 17 are penetrated through the adjusting lock plates 16, the adjusting lock plates 16 are matched with the threaded lock rods 17 to form a reliable locking structure. After the spacing of the pipe supporting clamping plate 4 is adjusted, the threaded lock rods 17 are tightened to firmly lock the stable supporting block 15 on the pipe supporting seat 3, which prevents the displacement of the pipe supporting clamping plate 4 due to vibration and other factors during the operation of the pipe, and ensures the stable clamping of the pipe.

[0033] The pipe supporting clamping plate 4 is provided with two, each pipe supporting clamping plate 4 is fixed on the moving block 13 at both ends of the double-end threaded rotating rod 12 through the stable supporting block 15, and the pipe supporting clamping plate 4 is arc-shaped and is supported on both sides of the lower end of the boiler pipe.

[0034] The rotating disc 6 is penetrated and fixed on the upper end of the supporting screw rod 2 and located on the lower end surface of the pipe supporting seat 3, the upper end surface of the rotating disc 6 is uniformly provided with strip-shaped supporting blocks 18 which uniformly support the pipe supporting seat 3 and assist the rotation of the rotating disc 6, the damper 8 can be self-adapted to stretch and contract according to the change of its position during the lifting process, and provides a buffering and damping effect; the strip-shaped supporting blocks 18 on the upper end surface are in contact with the lower end surface of the pipe supporting seat 3, which transmits the supporting force and assists the rotation of itself, the front and rear of the port of the sliding groove 11 and the surface of the pipe supporting seat 3 are uniformly provided with threaded lock holes 19, and the position of the stable supporting block 15 is locked after the threaded lock rods 17 on the adjusting lock plates 16 are locked in the threaded lock holes 19.

[0035] Specifically, during use, the height adjustment of the support is mainly realized through the cooperation of the supporting screw rod 2 and the pipe supporting block 1. The inner threaded groove 10 at the center of the end of the pipe supporting block 1 is threadedly connected with the supporting screw rod 2, when the rotating disc 6 is rotated, since the supporting screw rod 2 is fixed with the rotating disc 6 and the supporting screw rod 2 can only rotate along the axial direction due to the constraint of the inner threaded groove 10, the up and down lifting is realized. At this time, the supporting shaft seat 5 plays a role, which allows the supporting screw rod 2 to rotate while limiting the pipe supporting seat 3 from rotating, and ensures that the pipe supporting seat 3 can move up and down stably to adapt to different requirements of the height of the suspended support of the boiler pipe. The strip-shaped supporting blocks 18 on the rotating disc 6 assist the rotation of the rotating disc 6 on one hand, reduce the friction during rotation, and make the adjustment operation more easy; on the other hand, they are uniformly distributed on the upper end surface of the rotating disc 6, can uniformly transmit the supporting force to the pipe supporting seat 3, and ensure the stability of the support

[0036] In the clamping of pipes of different diameters, the cooperation of the double-threaded rotating rod 12 on the pipe support base 3 and the pipe support clamping plate 4 is relied on. The double-threaded rotating rod 12 has reverse threads at both ends, which are respectively screwed into the moving blocks 13. When the auxiliary rotating disc 14 is rotated, the double-threaded rotating rod 12 is rotated, and the moving blocks 13 at both ends are synchronously moved in opposite directions along the sliding groove 11. Since the two pipe support clamping plates 4 are fixed on the moving blocks 13 through the stable supporting blocks 15, the movement of the moving blocks 13 will change the distance between the pipe support clamping plates 4. After being adjusted to the appropriate position, the position of the stable supporting block 15 is locked by the cooperation of the threaded locking rod 17 on the locking plate 16 and the threaded locking hole 19 on the surface of the pipe support base 3, so that the pipes of different diameters are clamped firmly. The pipe support clamping plate 4 is designed in an arc shape and is attached to the lower end of the two sides of the boiler pipe, thereby increasing the contact area with the pipe, uniformly distributing the load of the pipe, and improving the stability of clamping.

[0037] In terms of buffering and shock absorption, the damper 8 installed in the installation cavity 7 at the end of the pipe support block 1 is mainly relied on. The installation cavity 7 is evenly arranged along the side of the end of the pipe support block 1, and the damper 8 is installed in each installation cavity 7. The damping top block 9 at the top end of the damper 8 is attached to the lower end surface of the rotating disc 6. When the support screw 2 drives the rotating disc 6 to rise and fall, the damper 8 will adaptively stretch and contract according to the position change of the rotating disc 6. When vibration occurs during the operation of the pipe, the vibration is transmitted to the pipe support base 3, and then the rotating disc 6 is displaced, and the damper 8 buffers the displacement of the rotating disc 6 through its damping characteristics, and offsets part of the vibration energy, thereby reducing the influence of vibration on the boiler pipe. Compared with the traditional damping method relying on fixed elastic pads, the circumferentially uniformly distributed dampers 8 can continuously provide stable and uniform damping effect in the full range of height adjustment of the support, especially in complex working conditions such as high temperature, avoiding the problem of damping failure caused by aging of elastic materials.

Although the present application 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 replacements to some technical features, as long as they are within the spirit and principles of the present application.
