Description

Technical Field

[0001] The utility model relates to the technical field of weld detection equipment, in particular to a steel structure weld detection device. Background Art

[0002] In order to ensure the welding quality of steel structures, it is often necessary to inspect the welds of steel structures, and then weld inspection equipment is needed. The utility model patent with patent application number CN202121755227.9 discloses a weld inspection ruler with a protective structure, which solves the problem that the existing weld inspection ruler does not have a certain dust-proof mechanism. When the user uses the weld inspection ruler for inspection, a large amount of iron filings and dust will enter the gap between the weld inspection ruler and the measuring piece. After long-term use, the dust will cause the active gap between the measuring piece and the weld inspection ruler to affect the rotation, reducing the practicality of the weld inspection ruler. According to the technical solution disclosed by it, when the existing crack detection equipment is used, on the one hand, it is easy to cause inaccurate detection of the width of the weld due to irregular welds or the ruler not being perpendicular to the weld, and at the same time, it is impossible to quickly detect whether there are cracks on the weld. On the other hand, when the personnel are recording, one hand is required to keep the detection equipment fixed, which is not conducive to the detection and recording work.

[0003] Therefore, how to design a steel structure weld detection device has become our current problem to be solved. Utility Model Content

[0007] Furthermore, the top end of the sliding rod is welded to the bottom of the transparent plate, and the magnetic sleeve is arranged on the outer side of the bottom end of the sliding rod.

[0008] Furthermore, the support rod is installed at the bottom of the sliding rod, and the top end of the support rod is connected to the bottom end of the sliding rod through a spring.

[0009] Furthermore, the upper sealing ring is bonded to the inner wall of the top end of the magnetic sleeve, and the upper sealing ring is sleeved on the outer side of the sliding rod.

[0010] Furthermore, a retaining ring is integrally formed on the outer side of the bottom end of the sliding rod, the top of the retaining ring is clamped on the bottom of the upper sealing ring, and the outer diameter of the retaining ring is smaller than the inner diameter of the magnetic sleeve.

[0011] Furthermore, a ball groove is formed at the bottom end of the support rod, the ball is clamped on the inner side of the ball groove, and a sealing ring is integrally formed on the outer side of the top end of the support rod, and the outer side of the sealing ring is clamped on the inner wall of the magnetic sleeve.

[0014] 2. When the steel structure weld detection device is in use, first place the magnetic sleeve on the outside of the steel structure, and then squeeze the handle downward so that the transparent plate squeezes the sliding rod downward. The sliding rod compresses the spring and squeezes the hydraulic oil inside the magnetic sleeve outward. The hydraulic oil passes through the retaining ring to push the upper sealing ring upward, and then pushes the magnetic ring outward, so that it is easy to move through the ball bearing at the bottom of the support rod for detection. When personnel need to record data, reduce the pressure on the handle, the spring pushes the sliding rod outward, and the magnetic sleeve moves downward and is adsorbed and fixed on the steel structure. There is no need for personnel to hold it in hand for fixed operation, which is convenient for data recording.
