Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment, and particularly relates to a column - type flaw detection auxiliary equipment. Background Art

[0002] Rail flaw detection is an important task in railway maintenance. The main purpose is to detect possible damages in the process of using rails, such as fractures, cracks, etc., as well as other problems affecting the service performance of rails. These damages may be caused by various factors, including material problems, repeated action of train dynamic loads, unreasonable track structure, etc. Each line of urban rail transit is equipped with a parking lot and a vehicle depot for vehicle parking and maintenance operations. The parking garage uses column - type tracks for vehicle parking and maintenance. The inspection pit is 1.5 meters high, and there is no walking path. There is no condition for flaw detection operation on site. During the operation, there is a risk of personnel and instruments falling, which greatly interferes with the manual flaw detection operation and poses a safety hazard. Existing flaw detection auxiliary equipment has problems such as low efficiency, inconvenient use, and low safety.

[0003] The patent with the publication number CN206493946U discloses a flaw detector auxiliary vehicle for a column - type maintenance depot, including an auxiliary vehicle body. The surface of the auxiliary vehicle body is provided with a vehicle body bearing plate. Body guardrails are arranged around the vehicle body bearing plate. A vehicle body quick - connector is arranged at the central connection of the vehicle body bearing plate. Two lifting rods are arranged on the auxiliary vehicle body. A flaw detector fixing bracket is arranged on the lifting rods. A horizontal adjustment knob is arranged at the top of the lifting rod, and a height adjustment knob is arranged on the side of the lifting rod. A rear walking wheel is arranged at the bottom of one end of the auxiliary vehicle body, and a front walking wheel is arranged at the bottom of the other end of the auxiliary vehicle body. A braking device is arranged between the front walking wheels. A pushing handrail is arranged at one end of the auxiliary vehicle body, and a brake handle is arranged on the pushing handrail, with a unique design of the vehicle body quick - connector. This device is convenient to disassemble and assemble, easy to carry and store. The flaw detector fixing bracket has high applicability and high safety. However, the flaw detector fixing bracket of this device can only adjust the height up and down, and cannot extend the flaw detector out of the auxiliary vehicle, so the flaw detection range is greatly limited. In addition, the braking device of this device is inconvenient to adjust and has poor stability, and still needs to be further improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a column - type flaw detection auxiliary equipment for the deficiencies of the existing technology, which is applicable to the overall ballast track flaw detection work of column - type inspection pits in vehicle depots and maintenance depots of each vehicle section.
