Device for detecting roundness of formed bamboo winding pipe gallery

Abstract

The invention relates to the technical field of pipeline detection, in particular to a roundness detection device for a formed bamboo winding pipe gallery, which comprises a supporting seat, telescopic cylinders, a lifting plate, a limiting part and a detection part, and is characterized in that the two telescopic cylinders are arranged at the upper end of the supporting seat in a bilateral symmetry manner, the tops of the two telescopic cylinders are jointly connected with the lifting plate, and the limiting part is arranged on the lifting plate; a detection part is mounted between the lifting plate and the supporting seat; an existing detector has the following problems that the detection length of the detector is limited, the roundness of the deeper position of the inner side wall of a pipeline cannot be detected, only the inner wall of the pipeline can be detected, the detector cannot detect the pipeline at a time, and the detection efficiency is low; rotary roundness detection can be performed on the inner and outer side walls of the pipe gallery at the same time, so that roundness detection on the circumferential surfaces of any positions of the inner and outer side walls of the pipe gallery can be completed at a time, the detection efficiency can be improved, and the operation steps can be reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a roundness detection device after forming a bamboo winding pipe gallery. Background technique [0002] The bamboo winding pipe gallery is a tubular pipe gallery made of bamboo as the main raw material, using thermosetting resin as the adhesive, and made by winding technology. Using bamboo material as the raw material can effectively save resources. [0003] After the bamboo winding pipe gallery is formed, its roundness needs to be inspected to ensure that the bamboo winding pipe gallery meets the requirements of use. At present, in the technical field of pipe roundness detection, the diameter of the end section of the pipe is usually measured to Judging whether the roundness of the pipeline meets the requirements, but it is not convenient to locate it when measuring the pipeline, which makes the pipeline deviate during the test, so the detection accuracy is low.

Problems solved by technology

[0003] After the bamboo winding pipe gallery is formed, its roundness needs to be inspected to ensure that the bamboo winding pipe gallery meets the requirements of use. At present, in the technical field of pipe roundness detection, the diameter of the end section of the pipe is usually measured to Judging whether the roundness of the pipeline meets the requirements, but it is not convenient to locate it when measuring the pipeline, which makes the pipeline deviate during the test, so the detection accuracy is low

[0004] For the above-mentioned problem of low detection accuracy, corresponding solutions are provided in the prior art, for example: the publication number is CN213542006U Chinese utility model patent discloses a kind of pipe roundness detector, the roundness detector that this patent relates to at first detects the pipeline Fix it, and then operate the detection assembly to rotate around the central axis of the detection housing. If the roundness of the pipe changes, the lifting rod will be displaced, and the spring will be compressed and deformed by the lifting block and the sliding shaft, and then the distance will be measured by infrared. The sensor detects the displacement of the sliding shaft to detect whether the roundness of the inner wall of the pipe is qualified

[0005] However, the roundness detector involved in the above-mentioned patent also has the following problems: 1. When the detector is in use, the handle needs to be manually operated to drive the slide bar to rotate around the detection housing. When there is a certain distance from the top of the pipe, it is inconvenient for the operator to put his hand into the pipe, so that he cannot smoothly detect the roundness of the inner wall of the pipe. Therefore, the detection length of the detector is limited, and it can only detect the inner wall of the pipe. To detect, there are limitations

[0006] 2. Since the detector can only detect the place where the inner wall of the pipe contacts and rolls with the ball, if it is necessary to detect the roundness of the entire circumferential surface of the inner wall of the pipe, it is necessary to frequently adjust the distance between the detector and the pipe. relative position, so it is impossible to perform one-time detection on the pipeline, the detection efficiency is low, and the operation is cumbersome
