Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to an adjustable detection device for checking the curvature of a steel pipe. Background Art

[0002] In recent years, many offshore wind power projects have emerged at home and abroad, involving many large-diameter steel pipe structures. Large-diameter steel pipes are long and are generally made up of multiple pipe sections. When manufacturing a single pipe section, the roundness of the pipe section needs to be strictly controlled. At present, the general operation of detecting the roundness of steel pipes is to make separate arc templates according to different pipe diameters for measurement, and then clamp the template on the inner wall of the steel plate to see whether the plate wall fits the template. Because different pipe diameters require templates that match the curvature, one template can only measure one pipe diameter. The more types of pipe diameters, the more templates there are, which will undoubtedly increase costs. Utility Model Content

[0003] The utility model aims to avoid the deficiencies of the above-mentioned prior art and provides an adjustable roundness detection device, which can adjust various radians. One device can meet the roundness detection of various pipe diameters, and there is no need to make multiple templates, thereby improving work efficiency and saving detection costs.

[0018] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be further described in detail below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model but not all. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1-2 , This embodiment provides an adjustable detection device for checking the curvature of a steel pipe, comprising a support frame 1, a measuring edge 2, and an adjustment rod 3;

[0020] The support frame 1 is provided with a plurality of lockable positioning frames 4, and the adjusting rods 3 are inserted in the positioning frames 4. Each adjusting rod 3 can be moved up and down and fixed in the positioning frames 4 to achieve the extension and retraction of the adjusting rod 3. In this embodiment, the positioning frames 4 are provided with fastening screws 5 to fix the adjusting rods 3.

[0021] The measuring edge 2 is hinged to a plurality of adjusting rods 3 , and the measuring edge 2 can obtain various curvature curves by extending and retracting the adjusting rods 3 to different lengths.

[0022] The support frame 1 of the device is a square frame, which plays a supporting and shaping role. The square frame is provided with two rows of lockable positioning frames 4, and each adjusting rod 3 passes through the two rows of positioning frames 4. The two positioning frames 4 prevent the adjusting rod 3 from deviating during the telescopic movement.

[0023] The measuring edge 2 is a bendable steel bar or aluminum plate.

[0024] The measuring edge 2 is divided into two sections, with a gap 6 in the middle. When used to detect the roundness of the inner diameter of the steel pipe 7, a position is reserved for the longitudinal weld 8, so that the detected roundness is not affected by the protrusion of the longitudinal weld 8.

[0025] Specifically, first draw the roundness arc to be measured on the ground or paper at a ratio of 1:1, then place the measuring edge 2 of the detection device close to the roundness arc, and then adjust the adjustment rods 3 to make the outer edge line of the measuring edge 2 coincide with the roundness arc.

[0026] After the measuring edge 2 matches the roundness arc, each adjusting rod 3 is locked, so that the supporting frame 1, the measuring edge 2 and the adjusting rod 3 of the whole device form a rigid fixation as a whole, and no deformation or displacement occurs. At this time, the roundness measuring device is completed;

[0027] The adjusted measuring edge 2 of the detection device is placed against the inner wall of the steel pipe 7. By observing the gap between the inner wall of the steel pipe 7 and the measuring edge 2 of the detection device, it can be determined whether the roundness of the steel pipe 7 meets the requirements. The middle gap of the measuring edge 2 can be staggered with the longitudinal weld bead 8 of the pipe section, and the roundness of the longitudinal seam area of ​​the pipe section can also be detected.

[0028] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
