Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline support technology, specifically a pipeline support device for the renovation of thermal power stations. Background Technology

[0002] In the renovation of heating stations, pipeline support devices are key equipment to ensure the stable operation of heating pipelines. With the upgrading of urban heating systems, existing heating stations need to adapt to the renovation needs such as pipeline layout adjustments, changes in pipe diameter, and the addition of new pipelines, which places higher demands on the mobility and adjustment performance of pipeline support devices.

[0003] In existing technologies, pipeline support devices used for heating station renovations mostly employ fixed supports. These supports are rigid and prone to severe vibrations under thermal expansion and contraction or external loads, which not only exacerbate pipeline wear but may also lead to loosening and leakage at connections. The moving adjustment mechanisms are rudimentary, relying heavily on manual prying or bolt-based adjustments. They lack smooth guiding and positioning components, making pipeline positioning laborious and difficult to align precisely. This is especially problematic in complex pipeline renovations, severely impacting construction efficiency and installation accuracy. This inconvenience in adjustment due to the inability to reduce vibration and poor mobility has become a prominent bottleneck restricting the quality and progress of heating station renovation projects. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline support device for the renovation of heating stations. It has the advantages of convenient installation and stable support. It solves the problem that the existing pipeline support devices for the renovation of heating stations cannot reduce vibration and improve the ease of pipeline movement when adjusting the support for heating pipelines, which makes the adjustment of pipeline support in pipeline renovation inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The pipeline support device for the renovation of a heating station includes a vibration damping support assembly, as well as an insulation sleeve and a hydraulic lift. The vibration damping support assembly has an insulation sleeve and a hydraulic lift installed at its upper and lower ends, respectively. The vibration damping support assembly includes a vibration damping tube. A damper is installed inside the vibration damping tube, and the damper housing is fixedly connected to the inner wall of the vibration damping tube. A lifting column is installed at the upper end of the damper, and the lifting column is movably connected to the inside of the vibration damping tube. A spring-loaded pressure plate is installed outside the lifting column. Movable grooves are provided on both sides of the vibration damping tube. A vibration damping spring is installed between the spring-loaded pressure plate and the damper. A pipeline support roller frame is installed at the upper end of the lifting column.

[0007] Preferably, the roller shaft of the pipe support roller frame is rotatably connected to the support.

[0008] It is worth noting that this method significantly reduces the frictional resistance between the pipe and the roller frame, making the pipe smoother during transportation or movement adjustment, reducing wear and energy loss caused by friction. At the same time, this connection method can adapt to possible small displacements or angle changes in the pipe, improving the flexibility and stability of the support, and effectively protecting the pipe and roller frame components.

[0009] Preferably, the spring-loaded pressure plate is fixedly connected to the lifting column.

[0010] It is worth noting that the fixed connection between the spring pressure plate and the lifting column has the advantage of ensuring the synchronization of their movements, avoiding structural loosening or functional failure caused by relative displacement, and improving overall stability. At the same time, the fixed connection can efficiently transmit the force of the spring to the lifting column through the pressure plate, reducing energy loss and enhancing the response efficiency and operational reliability of the lifting system.

[0011] Preferably, the movable groove and the shock absorber tube are integrally formed, and the two sides of the spring pressure plate are vertically movable through the movable groove.

[0012] It is worth noting that the integrated molding of the movable groove and the damping tube enhances the stability and connection strength of the overall structure, reduces assembly steps and potential loosening risks. The vertically movable arrangement of the spring pressure plate through the movable groove on both sides not only provides stable guidance for the spring pressure plate through the movable groove, ensuring its precise movement trajectory, but also improves the rigidity and deformation resistance of the overall device during movement through the structural cooperation of the integrated damping tube and the movable groove, thus balancing movement flexibility and structural reliability.

[0013] Preferably, the insulation sleeve is set at the upper end of the pipe support roller frame, and the insulation sleeve wraps around the thermal pipe, and the insulation sleeve itself is sealed with an adhesive tape.

[0014] It is worth noting that the insulation sleeve is set on the upper end of the pipe support roller frame and wraps around the thermal pipe, which can effectively reduce the heat loss of the thermal pipe and play a good role in insulation. At the same time, the insulation sleeve itself adopts an adhesive tape sealing setting, which can enhance its sealing performance, prevent the entry of cold air from affecting the insulation effect, and also prevent the inside of the insulation layer from getting damp, further ensuring the insulation performance and operational stability of the thermal pipe.

[0015] Preferably, a base plate is provided at the lower end of the damping tube, and the base plate is fixedly connected to the damping tube. It is worth noting that the fixed connection of the base plate to the lower end of the damping tube has the advantage that the base plate can provide a stable supporting foundation for the damping tube, enhance the stability of the overall structure, and at the same time, the force on the damping tube can be more evenly transferred to the connecting structure below through the base plate, reducing local stress concentration and improving the overall load-bearing capacity and the stability of the damping effect.

[0016] Preferably, the output end of the hydraulic lift is located on the lower end face of the base plate; each of the four corners of the base plate is provided with a screw, and the screw connects the base plate and the output end of the hydraulic lift via threads. It is worth noting that: the output end of the hydraulic lift is directly located on the lower end face of the base plate, which facilitates efficient transmission of lifting power; the screws at the four corners of the base plate connect it to the output end of the hydraulic lift via threads, ensuring the stability of the connection and allowing adjustment of the base plate's level through the threads, resulting in even force distribution on the base plate and thus improving the overall stability and reliability of the structure.

[0017] Preferably, lifting limit rods are provided inside both sides of the spring pressure plate, and the lifting limit rods are fixedly connected to the housing of the shock absorber tube, and the lifting limit rods are vertically movable through the internal holes on both sides of the spring pressure plate.

[0018] It is worth noting that the lifting limit rod is fixed to the shock absorber housing and vertically connected through the internal holes on both sides of the spring pressure plate. Its advantage is that it can accurately limit and guide the lifting of the spring pressure plate, effectively preventing the spring pressure plate from shifting or shaking during the movement, ensuring that it always moves stably in the vertical direction, thereby enhancing the stability and reliability of the overall structure during operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model uses a hydraulic lift to flexibly adjust the overall support height, and works with the base plate and the screws at the four corners to achieve a stable connection with the foundation. At the same time, the roller shaft of the pipe support roller frame is rotatably connected to the bracket, which can not only stably support the thermal pipe, but also adapt to the slight displacement of the pipe caused by thermal expansion and contraction. This solves the problem of fixed support height and easy support failure caused by pipe displacement in existing devices.

[0021] In the vibration damping support assembly, the damper inside the damping tube and the damping spring form a composite vibration damping structure. When the pipeline vibrates, the lifting column drives the lower pressure plate of the spring to move vertically along the movable groove and the lifting limit rod. The damping spring buffers the vibration impact force, and the damper further absorbs the vibration energy. Compared with the existing single spring vibration damping structure, it greatly improves the suppression effect on pipeline vibration and reduces the damage of vibration to the pipeline and support device.

[0030] To address the problem of inconvenient pipe support adjustments during heating station renovations due to the inability of existing pipe support devices to reduce vibration and improve the ease of pipe movement, the following technical solution is provided. Please refer to [link / reference]. Figure 1-5 ;

[0031] The pipeline support device for the renovation of a heating station includes a vibration damping support assembly 1, an insulation sleeve 2, and a hydraulic lift 3. The upper and lower ends of the vibration damping support assembly 1 are respectively equipped with the insulation sleeve 2 and the hydraulic lift 3. The vibration damping support assembly 1 includes a vibration damping tube 101. A damper 110 is installed inside the vibration damping tube 101, and the shell of the damper 110 is fixedly connected to the inner wall of the vibration damping tube 101. A lifting column 102 is installed at the upper end of the damper 110, and the lifting column 102 is movably connected to the inside of the vibration damping tube 101. A spring pressure plate 104 is installed outside the lifting column 102. Movable grooves 103 are provided on both sides of the vibration damping tube 101. A vibration damping spring 105 is installed between the spring pressure plate 104 and the damper 110. A pipeline support roller frame 107 is installed at the upper end of the lifting column 102.

[0032] The roller shaft of the pipe support roller frame 107 is rotatably connected to the support.

[0033] The spring-loaded pressure plate 104 is fixedly connected to the lifting column 102.

[0034] The movable groove 103 is integrally formed with the shock absorber tube 101, and the two sides of the spring pressure plate 104 are vertically movable through the movable groove 103.

[0035] The insulation sleeve 2 is set at the upper end of the pipe support roller frame 107, and the insulation sleeve 2 wraps around the thermal pipe, and the insulation sleeve 2 itself is sealed with an adhesive tape.

[0036] The lower end of the shock absorber tube 101 is provided with a base plate 108, and the base plate 108 is fixedly connected to the shock absorber tube 101.

[0037] The output end of the hydraulic lift 3 is located on the lower end face of the base plate 108; each of the four corners of the base plate 108 is provided with a screw 109, and the screw 109 threadedly connects the base plate 108 and the output end of the hydraulic lift 3.

[0038] Both sides of the spring pressure plate 104 are provided with lifting limit rods 106, and the lifting limit rods 106 are fixedly connected to the housing of the shock absorber tube 101. The lifting limit rods 106 are vertically and movably connected through the internal holes on both sides of the spring pressure plate 104.

[0039] Working principle: The overall support height can be flexibly adjusted by the hydraulic lift 3, and a stable connection with the foundation is achieved with the base plate 108 and the screws 109 at the four corners. At the same time, the roller shaft of the pipe support roller frame 107 is rotatably connected to the bracket, which can not only stably support the thermal pipe, but also adapt to the slight displacement of the pipe caused by thermal expansion and contraction. This solves the problem of fixed support height and easy support failure due to pipe displacement in existing devices. The damper 110 and the damping spring 105 inside the shock-absorbing tube 101 form a composite shock-absorbing structure. When the pipe vibrates, the lifting column 102 drives the lower pressure plate 104 of the spring to move vertically along the movable groove 103 and the lifting limit rod 106. The damping spring 105 buffers the vibration impact force, and the damper 110 further absorbs the vibration energy. Compared with the existing single spring shock-absorbing structure, the suppression effect of pipe vibration is greatly improved, and the damage of vibration to the pipe and support device is reduced.
