Technical Field

[0001] The invention belongs to the technical field of rail detection, and relates to a detection vehicle, in particular to a rail state dynamic detection vehicle. Background Art

[0002] Rails are an important part of railway tracks and are under tremendous pressure. As they are exposed to the elements all year round, they are subject to wind, rain, freezing and thawing, and train loads. The geometric dimensions of rails are constantly changing, the roadbed and ballast are constantly deforming, and the rails, connecting parts and sleepers are constantly wearing out, which causes the technical status of line equipment to change constantly. Therefore, it is important for the engineering department to master the changing rules of line equipment[1], detect the line status in a timely manner, and strengthen line detection management to ensure line quality and transportation safety.

[0003] After searching, it is found that a flaw detection vehicle for detecting the state of rails is disclosed in Chinese patent documents [Application No.: 202223305160.6; Publication No.: CN 219096706 U]. This flaw detection vehicle for detecting the state of rails relates to the field of rail detection technology. The present invention includes a vehicle floor, four seats are fixedly installed near the center of the top of the vehicle floor, a protective rod is fixedly connected to the outside of the seat near the top of the vehicle floor, a lifting assembly is extended downward and fixedly connected to the center of the vehicle floor, a T-shaped cylinder is fixedly connected to the center of the bottom of the lifting assembly, a collar is sleeved and rotatably connected to the outer surface of the T-shaped cylinder, and four rollers are installed below the vehicle floor. The present invention lifts the vehicle floor through the lifting assembly and makes the support point of the vehicle floor only the collar, and then pushes the vehicle floor to rotate with the center of the T-shaped cylinder, thereby adjusting the overall direction of the flaw detection vehicle so that the flaw detection vehicle is parallel to the rail. The whole process only requires one staff member to operate, and does not require too much labor and large equipment.

[0004] Although the lifting assembly disclosed in the patent lifts the vehicle floor and makes the vehicle floor support point only the sleeve, and then pushes the vehicle floor to rotate it about the center of the T-shaped cylinder, thereby adjusting the overall orientation of the flaw detection vehicle to make the flaw detection vehicle parallel to the rail, the entire process only requires one staff member to operate, and does not require excessive labor and large equipment. However, the staff needs to use tools to move the flaw detection vehicle to the middle of the rail, and then use the lifting assembly to make the rollers on the flaw detection vehicle fall onto the rail, which reduces work efficiency and increases workload.
