Description

Technical Field

[0001] The utility model belongs to the technical field of compensators, in particular to a shock-absorbing pipeline compensator. Background Art

[0002] The compensator is also called an expansion joint or telescopic joint. It consists of a bellows (an elastic element) that constitutes its working body and accessories such as end pipes, brackets, flanges, and conduits. The expansion joint is a flexible structure set on the container shell or pipeline to compensate for the additional stress caused by temperature difference and mechanical vibration. The effective expansion and contraction of the bellows, the working body, is used to absorb the dimensional changes caused by thermal expansion and contraction of pipelines, conduits, containers, etc., or to compensate for the axial, lateral and angular displacements of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction, and heating. In order to prevent the deformation or damage of the heating pipeline due to thermal elongation or temperature stress when the heating pipeline is heated, a compensator needs to be set on the pipeline to compensate for the thermal elongation of the pipeline, thereby reducing the stress of the pipe wall and the force acting on the valve or bracket structure; the existing compensator does not have a compression positioning function, which makes the compensator easy to spread, thereby occupying a large amount of transportation space during transportation and reducing the transportation volume. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shock-absorbing pipeline compensator, comprising a mounting hard pipe, one end of the mounting hard pipe is fixedly mounted with a first corrugated telescopic pipe, the end of the mounting hard pipe away from the first corrugated telescopic pipe is fixedly mounted with a second corrugated telescopic pipe, the end of the first corrugated telescopic pipe away from the mounting hard pipe is fixedly mounted with a second connecting flange, the end of the second corrugated telescopic pipe away from the mounting hard pipe is fixedly mounted with a first connecting flange, the surfaces of the first connecting flange and the second connecting flange are both annularly provided with a plurality of bolt connection holes at equal distances, and two equipment installations are symmetrically fixedly mounted on the surface of the mounting hard pipe A platform, four shock-absorbing damping rods are fixedly installed in a ring at equal distances between the sides of the first connecting flange and the second connecting flange where they are close to each other, first springs are provided on the surfaces of the four shock-absorbing damping rods, both ends of the four first springs are fixedly connected to the first connecting flange and the second connecting flange respectively, two positioning rods are fixedly installed on the sides of the first connecting flange and the second connecting flange close to the installation hard pipe, and limited clamps are movably installed on the ends of the four positioning rods close to the installation hard pipe through threads, and a clamping positioning component is provided between the sides of the two equipment mounting platforms that are away from each other, and the clamping positioning component matches the four positioning rods.

A plug hole is opened in the middle of the four positioning blocks, and two limit clamps are symmetrically arranged inside the four plug holes. A first rectangular rod is fixedly mounted in the middle of one side of the limit clamp, and a first rectangular sleeve is sleeved on the surface of the first rectangular rod. The first rectangular sleeve is respectively fixedly mounted on both sides of the four positioning blocks, and the limit clamps are matched with the positioning plug rods.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the operator connects the first connecting flange and the second connecting flange to the pipeline through the cooperation of several bolt connection holes and bolts on the first connecting flange and the second connecting flange, and removes four limit clamps connected by threads; when in use, when the first connecting flange and the second connecting flange are subjected to the movement and extrusion of the pipeline, the first corrugated telescopic tube and the second corrugated telescopic tube will be driven to contract in the direction of installing the hard pipe, and the first connecting flange and the second connecting flange will also squeeze the four shock-absorbing damping rods and the four first springs while moving, and the four shock-absorbing damping rods and the four first springs can effectively perform shock absorption and buffering through the cooperation of the four shock-absorbing damping rods and the four first springs, thereby ensuring its stability during use;

[0008] When transportation is required, the operator squeezes the first connecting flange and the second connecting flange inward at the same time, inserts the four positioning rods and the four limit clamps into the four plug-in holes in the four positioning blocks, and pushes the limit clamps outward.

Four shock-absorbing damping rods 6 are fixedly installed in a ring at equal distances between the sides of the connecting flanges 12 that are close to each other. The surfaces of the four shock-absorbing damping rods 6 are provided with first springs 7. The two ends of the four first springs 7 are respectively fixedly connected to the first connecting flange 4 and the second connecting flange 12. Two positioning rods 9 are fixedly installed on the sides of the first connecting flange 4 and the second connecting flange 12 close to the installation pipe 1. Limiting clamps 10 are movably installed on the ends of the four positioning rods 9 close to the installation pipe 1 through threads. A clamping positioning assembly is provided between the sides of the two equipment mounting platforms 8 that are away from each other, and the clamping positioning assembly matches the four positioning rods 9.

[0017] The operator connects the first connecting flange 4 and the second connecting flange 12 to the pipeline through the cooperation of the several bolt connection holes 5 and the bolts, and removes the four limit clamps 10 connected by the threaded connection. When in use, when the first connecting flange 4 and the second connecting flange 12 are squeezed by the movement of the pipeline, the first corrugated telescopic tube 2 and the second corrugated telescopic tube 3 will be driven to shrink in the direction of installing the hard pipe 1. When the first connecting flange 4 and the second connecting flange 12 move, the four shock-absorbing damping rods 6 and the four first springs 7 will be squeezed. The cooperation with the four first springs 7 can effectively reduce shock and buffer, ensuring its stability during use; when transportation is required, the operator squeezes the first connecting flange 4 and the second connecting flange 12 inward at the same time, and inserts the four positioning rods 9 and the four limit chucks 10 into the card-jointed positioning component, and the four positioning rods 9 are clamped by the card-jointed positioning component, and all form a limit with the limit chucks 10, so as to quickly perform compression positioning; this enables the compensator to have a compression positioning function, avoiding the compensator from dispersing after compression, thereby reducing its own occupied space and increasing the transportation volume.

When the limit clamps 14 are pushed, they drive the first rectangular rod 15 to move outward along the first rectangular sleeve 16. When the first rectangular rod 15 moves outward, it drives the second rectangular rod 18 to move outward along the second rectangular sleeve 19, and squeezes the second spring 21 through the fixed baffle 17 at the same time. When the limit clamp 10 passes over the limit clamp 14, the second spring 21 pushes the limit clamp 14 to move and reset through its own elastic force, thereby clamping the positioning rod 9 and forming a limit with the limit clamp 10, thereby quickly performing compression positioning.
