Description

Technical Field

[0001] The utility model relates to the technical field of pipe joint thickness detection, in particular to a pipe joint thickness detection device. Background Art

[0002] In the field of temporary steel structure construction in civil engineering, a large number of steel pipes are usually used to erect steel pipe support frames to meet various needs at the construction site. Since such supports are used in many scenarios and have a large demand, they are usually installed and disassembled back and forth by knocking in violation of the regulations, resulting in a large number of cases of rust and deformation.

[0003] After the steel pipe rusts, its external surface area and volume will increase. After the steel pipe is deformed, its structure will exceed the external design limit. Both of these situations will cause the external dimensions of the steel pipe to deviate or change from the original design. After the change, whether the steel pipe can be inserted into the designed holes and cavities becomes the main problem to be faced. For inspecting whether the thickness of the steel pipe and the inner and outer diameter dimensions meet the design requirements, the current construction methods are as follows:

[0004] ① Visual inspection by workers, and those with severe deformation or rust are directly removed;

[0005] ② Use a vernier caliper to measure the inner and outer diameters of the steel pipe and measure the wall thickness of the steel pipe, and select a qualified number of points for inspection;

[0006] ③ Select a part of a batch of steel pipes for trial assembly. If the trial assembly is qualified, the whole batch is qualified; if the trial assembly is unqualified, the whole batch is unqualified.

[0007] Problems existing:

[0008] ① Visual inspection by the human eye has a large human factor and it is difficult to judge small errors; moreover, what needs to be observed are the inner diameter, outer diameter and thickness of the steel pipe, and it is basically impossible to distinguish details;

[0009] ② When using a vernier caliper for detection, only part of the steel pipes in a batch can be selected, and several points are selected on these steel pipes for measurement. The number of detections is small, the efficiency is low, and there are also factors such as human errors;

[0010] ③ When using the method of sampling inspection and trial assembly, the coverage is small, only a small part of the sampling can be covered, and it is necessary to continuously assemble and disassemble, wasting manpower, with low efficiency, and prone to danger. Content of the Utility Model

[0023] The utility model has achieved the following technical effects compared with the prior art:

[0024] The pipe joint thickness detection device provided by the utility model respectively sets a clamping member at both ends of the main frame. Each clamping member has a clamping gap with the same wall thickness as the pipe joint to be detected. The thickness dimension is fixed by the set clamping gap. When detecting the thickness of the pipe joint to be detected, the end of the pipe joint to be detected can be inserted into the two clamping gaps, and the main frame drives each clamping member to rotate around the axis of the pipe joint to be detected. Based on the deformation or rust thickening at the detection position of the pipe joint to be detected, the main frame and each clamping member cannot pass through here. Therefore, when it cannot continue to rotate, it means that the detection result of the pipe joint to be detected fails. If it can rotate smoothly for one week, it means that the detection result of the pipe joint to be detected passes; and setting two clamping members can reduce the rotation angle and improve the detection efficiency; the whole detection operation is simple and convenient, without the need to assemble and disassemble the pipe joint to be detected, reducing the manual labor amount and improving the efficiency.

[0026] Furthermore, the telescopic movement of the first telescopic rod relative to the fixed body can adjust the size of the clamping gap, so as to adapt to the detection of pipe joints to be detected with different thicknesses.

[0027] Furthermore, the first abutting member adopts a combination of a cylindrical rod, a roller and a sealing bottom support. The roller is in rolling contact with the side wall of the pipe joint to be detected, reducing friction, extending the service life, and reducing the rotation resistance during detection.

[0028] Furthermore, the first abutting member and the second abutting member have the same structure, which can ensure small rotational resistance during detection, and the same structure for the two parts can achieve the universality of parts, reducing the manufacturing and maintenance costs.

[0029] Furthermore, two second telescopic rods are adopted at both ends of the main frame, which can be used for detecting pipe joints with different pipe diameters to expand the scope of application.

[0030] Furthermore, the handle provided on the main frame can facilitate the operator to hold and rotate, improving the rotational detection efficiency.

[0031] Furthermore, by the cooperation of the rotating gear and the racks on the two second telescopic rods, the synchronous telescopic driving of the two second telescopic rods is realized. The adjusting knob provided on the main frame facilitates the operator to hold and rotate and drive the rotating gear to rotate, and the provided limiting member facilitates the rotational locking of the adjusting knob (i.e., the rotating gear), so as to maintain the stability of the dimension to be detected.

[0032] Furthermore, the scale lines and scale values provided on the first telescopic rod can facilitate and clearly know the size of the clamping gap.

[0049] By respectively arranging a clamping member 20 at both ends of the main frame 10, each clamping member 20 has a clamping gap 24 with the same wall thickness as that of the pipe joint to be measured. The thickness dimension is fixed by the arranged clamping gap 24. When detecting the thickness of the pipe joint to be measured, the end of the pipe joint to be measured can be inserted into the two clamping gaps 24, and the main frame 10 drives each clamping member 20 to rotate around the axis of the pipe joint to be measured. Based on the deformation or rust thickening at the detection position of the pipe joint to be measured, the main frame 10 and each clamping member 20 cannot pass through here. Therefore, when it cannot continue to rotate, it means that the detection result of the pipe joint to be measured fails.
