Description

Technical Field

[0001] The utility model belongs to the technical field of vibration reduction structures, in particular to an adjustable movable pipeline vibration reduction and damping device. Background Art

[0002] At present, vibrations of various pipelines in chemical production facilities are common, affecting the sealing performance and service life of pipelines, and even posing the risk of rupture and leakage, which seriously restricts the safety and stability of the chemical industry. During the research on pressure control and tail gas recycling technology of Fischer-Tropsch synthesis system, it was found during the inspection process that the running pipelines in the device would experience excessive vibration, pipeline leakage and cracking.

[0003] Common pipeline vibration reduction methods include optimizing pipeline layout, increasing support and fixation, installing buffer devices, controlling fluid flow rate and pressure, etc. Since chemical pipelines often involve high-temperature, high-pressure, toxic and harmful media, once the design is completed and put into use, the cost of re-optimizing the layout is high, and the buffer device has limited pressure resistance and cannot be completely replaced. In addition, due to the limitations of process requirements, the flow rate and pressure adjustment range of the fluid in the pipeline are small, and there are many variables during operation, and the pipeline vibration conditions change under different working conditions. Therefore, the pipeline vibration reduction methods are very limited in actual operation. Utility Model Content

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0020] like Figure 1As shown, this embodiment provides an adjustable movable pipeline vibration reduction and damping device, including a support ring 1, a coarse adjustment support rod 2, a limit anti-tilt piston 5, a support seat 6 and a fine adjustment leg 7; the four corners of the bottom surface of the support seat 6 are connected with fine adjustment legs 7, and the height of the support seat 6 is adjusted through the fine adjustment legs 7. The fine adjustment legs 7 are screw structures, and an enlarged support foot is provided at the bottom of the screw structure. The fine adjustment legs 7 are connected to the adjustment nut 9, and the height of the support seat 6 is fixed by adjusting the position of the adjustment nut 9. In order to improve stability, an anti-skid pad is provided at the bottom of the fine adjustment leg 7.

[0021] A cylindrical sleeve 10 is connected to the top surface of the support seat 6; the bottom of the coarse adjustment support rod 2 extends into the sleeve 10 and can move up and down in the sleeve 10; the coarse adjustment support rod 2 is connected with a coarse adjustment nut 3 and a locking nut 4, and the coarse adjustment support rod 2 is fixedly connected to the sleeve 10 through the coarse adjustment nut 3; the locking nut 4 is used to further lock the coarse adjustment support rod 2 and the sleeve 10. A limited anti-tilt piston 5 is connected to the bottom of the coarse adjustment support rod 2, and the limited anti-tilt piston 5 is slidably connected to the inner wall of the sleeve 10; the limited anti-tilt piston 5 is a metal block, which is used to increase the supporting force of the coarse adjustment support rod 2 and effectively prevent the coarse adjustment support rod 2 from loosening and tilting when it is affected by vibration, thereby ensuring the vertical stability of the support. A support ring 1 is connected to the top of the coarse adjustment support rod 2, and the top surface of the support ring 1 is provided with an arc-shaped card slot for supporting the pipe, and the inner wall of the card slot is provided with a damping flexible cushion layer made of rubber material, which further forms a buffering effect on the pipe.

[0022] A level bubble 8 is provided on the surface of the support base 6 ; the level bubble 8 is used to level the support base 6 .

[0023] The working principle of this device is:

[0024] Place the device on the ground below the pipeline, and use the anti-skid pads at the bottom of the fine-adjustment legs 7 to prevent the fine-adjustment legs 7 from tipping over; according to the pipe diameter and height from the ground, adjust the locking nut 4 and the coarse-adjustment nut 3 counterclockwise to the top of the coarse-adjustment support rod 2, and adjust the fine-adjustment legs 7 to the shortest; confirm that the damping flexible cushion layer in the slot of the support ring 1 has been installed and is higher than the slot, and tighten the coarse-adjustment nut 3 and the locking nut 4 clockwise; after the coarse adjustment is completed, use the four fine-adjustment legs 7 to accurately adjust the height and level. If it is the first time to support the pipeline and the best pipeline support position is not clear, you can use a vibration meter to install the device at different positions of the pipeline, conduct multi-point support tests, and finally determine the position that needs support, and then fix the device.

[0025] The support ring of the device is provided with a slot for installing a damping flexible cushion layer, and the thickness of the cushion layer is higher than the height of the slot, which can effectively utilize the elastic balance of the cushion layer to buffer vibration and achieve low-cost shock reduction.

[0026] The device adjusts the support height through the coarse adjustment nut 3 and the fine adjustment leg 7. In addition, a locking nut 4 and a horizontal bubble 8 are added to greatly improve the adjustment height range and adjustment accuracy, thereby ensuring the stability of the support.

[0027] The device adds a limit anti-tilt piston 5 in the sleeve 10 to effectively prevent the coarse adjustment support rod 2 from being separated from the support seat 6, thereby ensuring that the support is vertical and stable.

[0028] The above content is a further detailed description of the utility model in combination with a specific preferred implementation method. It cannot be determined that the specific implementation methods of the utility model are limited to this. For ordinary technicians in the technical field to which the utility model belongs, they can make several simple deductions or substitutions without departing from the utility model, which should be regarded as belonging to the utility model and the scope of patent protection determined by the submitted claims.
