[0002] The brake pipe is an important component of a railway freight car. It is often necessary to measure the installation position of the brake pipe. Due to the various shapes of the brake pipe, there are S-shaped, L-shaped, U-shaped and three-dimensional space pipes. Three-dimensional detection equipment needs multi-point, multiple times, three-dimensional positioning to measure the space, and then calculates the installation position parameters of the brake pipe. The operation is complicated, the positioning is difficult, and the positioning is inaccurate. However, the three-dimensional detection equipment is complicated to manufacture, inconvenient to use, and high in cost. Single-pipe inspection takes a long time and is inefficient. Only random inspections can be used, and it is impossible to ensure that all brake pipes are inspected for installation positions. Therefore, it is difficult to accurately control the quality of each brake pipe, which hinders production progress and reduces production quality. , increasing the risk
[0003] The Chinese patent discloses a "Composite Measuring Platform Composed of Brake Tubes for Railway Freight Cars" (Patent No. ZL: 200720032469.9). The positioning key of the movable head and the positioning key of the fixed head are arranged on the working platform, and the positioning key of the movable head and the positioning key of the fixed head are in clearance fit or interference fit with the chute. The structure of the above-mentioned patent is complex, inconvenient to operate, low in accuracy, easy to damage, and low in measurement efficiency
