Description

Technical Field

[0001] The utility model relates to the technical field of pipe inner diameter detection, in particular to a pipe inner diameter insertion detection device. Background Technique

[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. For such supports, due to their many usage scenarios and large demand, they are usually installed and disassembled by knocking back and forth, resulting in a large number of rusted and deformed situations.

[0003] After the steel pipe is rusted, 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 outer dimension 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 inner diameter of the steel pipe meets the requirements and whether it can be smoothly inserted into the designed position, the current construction methods are as follows:

[0004] ① Manual observation, and those with severe deformation or rust are directly removed.

[0005] ② Use a vernier caliper to measure the inner diameter direction 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] However, there are problems with the existing detection methods:

[0008] ① Observed by the naked eye of humans, the human factor is large, and it is difficult to judge small errors. For insertability, there are only two states: passing and not passing. Exceeding the limit means that it cannot be inserted and cannot be used.

[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 selected steel pipes for measurement. The detection quantity is small, the efficiency is low, and there are also factors such as human error.

[0010] ③ 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

[0044] By setting the distance formed by the outer sides of the first abutting member 20 and the second abutting member 30 to a specified size, that is, the normal inner diameter size of the pipe to be measured, during the detection, rotate the main frame 10. The first abutting member 20 and the second abutting member 30 closely adhere to the inner wall of the pipe to be measured and rotate synchronously. When it gets stuck and cannot rotate, it indicates that the inner diameter at this position of the pipe to be measured is small, that is, the inner diameter insertion detection result is unqualified; the whole detection operation is simple and convenient, without the need to assemble and disassemble the pipe to be measured, reducing the manual labor amount, improving the efficiency, and one person can complete the detection work of a large number of pipes to be measured. When necessary, it can easily achieve full coverage detection, effectively improving the detection accuracy.

[0045] Specifically, both the first abutting member 20 and the second abutting member 30 can be detachably connected to the main frame 10, thereby reducing the occupied space and being convenient to carry; and the operation is simple, reducing the requirement level of personnel detection operation, and it can be operated without professional training. The detection result has high accuracy and small human error; compared with the existing trial assembly, it reduces the manual labor intensity, improves the detection efficiency, and only one person is needed to operate to complete a large number of measurements. When necessary, it can easily achieve full coverage detection.

[0046] Specifically, the inner diameter insertion detection device 100 of this embodiment mainly but not limited to detects the inner diameter of the inserted part of the pipe to be measured; that is, when it is used to detect the inner diameter of the inserted part of the pipe to be measured, the lengths of the first abutting member 20 and the second abutting member 30 are the same as the length of the inserted part of the pipe to be measured.

[0047] Specifically, all unqualified positions (the inner diameter becomes smaller due to rust or deformation causes the position size to deform) will be stuck during the detection process, so that it is fast and efficient to find out the over-limit parts; it avoids repeated erection and disassembly, is safe and efficient, greatly improves the construction efficiency, reduces the manpower consumption, and saves the manpower cost and expenditure.

[0048] Specifically, when in use, as Figure 5 shown, place both the first abutting member 20 and the second abutting member 30 in the pipe to be measured and rotate one week. If it can rotate smoothly, the result is that the detection passes; if it gets stuck and cannot rotate, the corresponding position is the result of unqualified inner diameter insertion detection; after use, take out the inner diameter insertion detection device 100 of this embodiment.

The main frame 10 has telescopic rods 11 at both ends, and the telescopic rods 11 drive the first abutting member 20 and the second abutting member 30 to expand and contract, so as to be applicable to the detection of the inner diameter of the to-be-detected tube with different inner diameters.

[0051] In an alternative solution of this embodiment, preferably, scale lines and scale values are engraved on the telescopic rod 11 along its telescopic direction. The scale lines and scale values set on the telescopic rod 11 facilitate the inspectors to directly view and adjust the required detection dimensions.

[0052] Specifically, the scale value can be the inner radius data of the to-be-detected tube (that is, the distance value from the outer side of the first abutting member 20 or the second abutting member 30 to the central axis of the main frame 10), or it can be directly the inner diameter data of the to-be-detected tube (that is, the distance value between the outer sides of the first abutting member 20 and the second abutting member 30).

[0055] Specifically, based on the fact that the handle 12 is located at the central position of the main frame 10, therefore, the position of the adjustment knob 17 can be set to a position biased towards the first abutting member 20 or towards the second abutting member 30, as Figure 1 shown. At this time, the corresponding rotation of the rotating gear 14 can be towards the same side.

By adopting the roller 22, that is, the form of rolling contact between the roller 22 and the inner wall of the pipe to be measured, the friction is reduced and the service life is prolonged; and the roller 22 is sleeved on the rotating shaft 21 and does not come out through the sealing bottom bracket 23, and its structure is simple and convenient.
