Description

Technical Field

[0001] The utility model relates to the technical field of DMO light removal towers, and particularly relates to a fixing device for DMO light removal tower pipeline demolition. Background Technique

[0002] A light removal tower is a device that uses the difference in volatility of substances to remove light components from a mixture. This device is widely used in industrial fields such as oil refining and chemical engineering. Its main function is to separate light hydrocarbons or other light components in the mixture through processes such as heating and fractionation.

[0003] During the use of the existing fixing device for DMO light removal tower pipeline demolition, when fixing the pipeline, the clamping plate is usually driven by a mechanical device to move and clamp the pipeline to ensure that the pipeline does not shift during the demolition process. The power of the mechanical device is set during production. If the clamping force is too large, it will cause physical damage to the pipeline and the situation of pipeline deformation will occur, thus increasing the risk of pipeline damage. The damaged pipeline needs to be replaced or repaired, which will further increase the economic burden of the project. Moreover, due to the different laying heights of the pipelines, the fixing device needs to be adjusted to the corresponding height to fix the pipeline. However, the lifting mechanism of some fixing devices fails to fully consider the operation convenience during design, resulting in insufficient integration between components. Operators need to frequently switch tools or adjust multiple independent components, increasing the complexity of the operation, thereby reducing the use convenience. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for DMO light removal tower pipeline demolition to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for DMO light removal tower pipeline demolition, including a connecting plate, a bottom plate is arranged below the connecting plate, a circular ring frame is arranged on the top of the connecting plate, and further includes:

[0006] A driving component arranged on the top of the connecting plate, a rotating ring is rotatably connected to the outside of the circular ring frame, a transmission component connected to the driving component is arranged inside the rotating ring, adjusting components for fixing the pipeline are arranged on the outside of both the circular ring frame and the rotating ring, a connecting seat is arranged on the outside of the adjusting component, a buffer component for protecting the pipeline from being damaged due to excessive tightening is arranged on one side of the connecting seat, and a clamping block is arranged at one end of the buffer component;

[0007] A rotating component is arranged on one side of the bottom plate, a moving shaft is arranged on the outside of the rotating component, a guiding groove is slidably connected to the outside of the moving shaft, and folding components for adjusting the height of the connecting plate are arranged at both ends of the moving shaft.

[0012] Preferably, the rotating assembly includes a motor arranged on one side of the bottom plate, and a bidirectional screw rod is arranged at the output end of the motor.

[0013] Preferably, the folding assembly includes a first rotating rod rotating at one end of the moving shaft, and a second rotating rod is rotatably connected to the outside of the first rotating rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The present utility model pulls the fixed rod through the connecting ring, so that the rotating ring rotates slightly along the outside of the annular frame. While the rotating ring rotates, the tightening rod on one side of the fixed seat follows the movement. The movable seat will generate a rotational displacement under the change of the position of the tightening rod, so that the tightening rod slides along the inside of the movable seat, so that the four tightening rods are tightened towards the center point of the annular frame. When the clamping block touches the outside of the pipeline, the guide rod slides along the inside of the connecting seat, and the impact force generated when the adjusting assembly fixes the pipeline is reduced by the elastic force generated by the spring, and then the fixing of the pipeline is completed; the motor drives the bidirectional screw rod to rotate, so that the moving shaft threadedly connected to the outside of the bidirectional screw rod moves. While the moving shaft slides inside the guide groove, it drives the first rotating rod to move accordingly. As the first rotating rod and the second rotating rod move, the connecting plate is driven to move by the change of the rotation angle, thereby completing the height adjustment and improving the convenience of use.

By providing the rotating seat 41, it is convenient for one end of the air cylinder 42 to rotate inside it; an air cylinder 42 is arranged inside the rotating seat 41. By providing the air cylinder 42, when its piston rod moves, it drives the rotating ring 5 fixed with the fixed rod 62 to rotate; the transmission assembly 6 includes a connecting ring 61 arranged on the piston rod of the air cylinder 42. The inner side of the connecting ring 61 is rotatably connected with a fixed rod 62. By providing the transmission assembly 6, it is convenient for the air cylinder 42 to be connected with the rotating ring 5 through the transmission assembly 6; the adjusting assembly 7 includes a fixed seat 71 fixed to the outside of the rotating ring 5. By providing the fixed seat 71, the fixed seat 71 is fixed to the outside of the annular frame 3. When the rotating ring 5 rotates slightly, the tightening rod 72 on one side of the fixed seat 71 moves accordingly. The movable seat 73 will generate a rotational displacement under the change of the position of the tightening rod 72, so that the four tightening rods 72 slide along the inside of the movable seat 73, thereby tightening the four tightening rods 72 towards the center point of the annular frame 3 to complete the fixation of the light-removing tower pipeline; the outside of the annular frame 3 is rotatably connected with a movable seat 73. By providing the movable seat 73, while the tightening rod 72 rotates, it slides inside it, so that the diameter inside the four tightening rods 72 can be adjusted; one side of the fixed seat 71 is fixedly connected with a tightening rod 72. By providing the tightening rod 72, it is convenient to fix pipelines with different diameters and improve the stability during demolition; one end of the tightening rod 72 is slidably connected with the movable seat 73; the buffer assembly 9 includes a guide rod 91 sliding inside the connecting seat 8. By providing the guide rod 91, when the clamping block 10 contacts the outside of the pipeline, the guide rod 91 slides along the inside of the connecting seat 8 to improve the stability of the movement of the clamping block 10; a spring 92 is sleeved outside the guide rod 91. By providing the spring 92, the elastic force generated by it can reduce the impact force when the adjusting assembly 7 fixes the pipeline, and reduce the risk of damage to the pipeline during the fixation process.

[0025] The rotating assembly 11 includes a motor 111 arranged on one side of the bottom plate 2. By providing the motor 111, it can drive the bidirectional screw 112 to rotate when starting; the output end of the motor 111 is provided with a bidirectional screw 112. By providing the bidirectional screw 112, it is convenient to drive the moving shaft 12 provided with a threaded hole to move horizontally during rotation; the folding assembly 14 includes a first rotating rod 141 rotating at one end of the moving shaft 12. By providing the first rotating rod 141, it is convenient for one end of the moving shaft 12 to move along with it when the moving shaft 12 moves; the outside of the first rotating rod 141 is rotatably connected with a second rotating rod 142. By providing the second rotating rod 142, it is convenient for it to rotate together with the first rotating rod 141, and drive the connecting plate 1 to move up and down through the change of the rotation angle.

[0026] Working principle: During use, when fixing the pipeline, first pass the pipeline through the inside of the annular frame 3. Then, the air cylinder 42 is started, and the piston rod extends accordingly. The fixing rod 62 is pulled through the connecting ring 61, causing the rotating ring 5 to rotate slightly along the outside of the annular frame 3. While the rotating ring 5 rotates, the tightening rod 72 on one side of the fixed seat 71 moves accordingly. The movable seat 73 will generate a rotational displacement under the position change of the tightening rod 72, so that the tightening rod 72 slides along the inside of the movable seat 73, thereby causing the four tightening rods 72 to tighten towards the center point of the annular frame 3. When the clamping block 10 contacts the outside of the pipeline, the guide rod 91 slides along the inside of the connecting seat 8, and the elastic force generated by the spring 92 reduces the impact force when the adjusting assembly 7 fixes the pipeline. Subsequently, the fixing of the pipeline is completed. When the height of the device needs to be adjusted, start the motor 111 to drive the rotation of the bidirectional screw 112, causing the moving shaft 12 threadedly connected to the outside of the bidirectional screw 112 to move. While the moving shaft 12 slides inside the guide groove 13, it drives the first rotating rod 141 to move accordingly. As the first rotating rod 141 and the second rotating rod 142 move, the connecting plate 1 is driven to move through the change in the rotation angle, thus completing the height adjustment.
