Description

Technical Field

[0001] The utility model relates to the technical field of measurement auxiliary devices, in particular to a depth measurement auxiliary device for rail parent material and weld defect positions based on on-site application conditions. Background Art

[0002] Rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transfer it to the sleepers. Rails must provide a continuous, smooth and least-resistance rolling surface for the wheels. Since rails occupy an important position in railway engineering, it is necessary to inspect the installed rails.

[0003] In order to facilitate the detection of rails, the prior art has made many improvements to rail detection devices, such as the patent with patent announcement number CN219385838U, which discloses a rail head transverse displacement measuring device, including a housing, a movable ejector, a rubber snap ring, a spring and a mounting seat; the mounting seat is installed on the sleeper, the upper side of the mounting seat is connected to the housing, the surface of the housing is marked with scales, the movable ejector is slidably connected to the housing, a driving ring is provided in the middle of the movable ejector, the rubber snap ring is sleeved on the outside of the housing, the side of the rubber snap ring is close to the driving ring, the spring connects the tail of the movable ejector and the mounting seat, the movable ejector contacts the rail head of the rail, and generates a pre-compression force on the spring, and a gap is left between the driving ring and the housing in the horizontal direction. The utility model device measures the maximum transverse displacement of the rail head by means of a movable ejector that slides in the housing, in conjunction with a spring and a rubber snap ring. The device has a small number of parts, a simple and reliable structure, does not require power and acquisition equipment, and has the characteristics of simple structure and convenient operation.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

After welding, the welding position of the rails needs to be processed and it is ensured that there are no concave defects at the weld positions of the two adjacent rails. Therefore, it is necessary to detect the weld positions of the rails. The iron standard stipulates that the depth of the defect position of the rail parent material and the weld shall not exceed 0.5mm. Currently, a depth gauge is used for measurement. It is inconvenient for the depth gauge to measure the curved part of the rail waist. Therefore, this field urgently needs to improve the auxiliary device for measuring the depth of the rail parent material and weld defect position based on field application conditions, so as to solve the defects of the prior art.
