Pipeline diameter changing device

Abstract

The invention aims to solve the problem that the diameter of a pipeline is not easy to adjust in the prior art, and discloses a pipeline diameter changing device. The pipeline diameter changing devicecomprises a first rotating shaft, a guide wheel, a wheel frame, a push plate, a first spiral spring, a guide rod, a mounting box, a first guide pipe, a second spiral spring, a sliding rod, a second guide pipe, an extrusion plate, a rotating rod, a third spiral spring, a baffle, a top plate, an end cover, an ejector rod, a fourth spiral spring, a sleeve, a rack, a first motor, a supporting frame,a second rotating shaft, a gear, a pull rope, a rotating cylinder, a rack, a sliding frame, a fifth spiral spring, a second motor, a guide ring, a connecting frame, a pull ring, a pipeline body and athird motor. According to the pipeline diameter changing device, the device can move in the pipeline through the driving of the third motor, and meanwhile, the extrusion plate can be used for extruding the pipeline through the driving of the first motor, so that the fine adjustment of the diameter of the pipeline is realized, and meanwhile, the deformation part can be conveniently repaired.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a pipeline diameter changing device. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Due to its unique characteristics, pipelines are widely used in many industries and fields. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] The diameter of the pipes used in daily use is generally not adjustable, especially for some pipes used in gas experiments. Fine-tuning the diameter of the pipes may change the pressure, which will bring different experimental results. If the pipes used are deformed , will also affect the dredging in the pipeline, and it is not easy to quickly repair the slightly deformed pipeline, ...

Problems solved by technology

[0003] The diameter of the pipes used in daily use is generally not adjustable, especially for some pipes used in gas experiments. Fine-tuning the diameter of the pipes may change the pressure, which will bring different experimental results. If the pipes used are deformed , will also affect the dredging in the pipeline, and it is not easy to quickly repair the slightly deformed pipeline, so it is not easy to quickly adjust the diameter of the pipeline. In order to adjust the diameter of the pipeline, it is urgent to design a pipeline diameter changing device to solve the existing problems. lack of technology
