Description

Technical Field

[0001] The utility model relates to the technical field of passenger car bogies, in particular to a bogie alignment detection platform. Background Art

[0002] After the cross-bracing device of the cross-bracing bogie is assembled, the bogie must be inspected for correct position before the wheelset is installed;

[0003] According to the Chinese patent announcement number: CN217930214U, a bogie alignment detection platform is disclosed, which uses an X-axis measuring component to measure the coordinate value of the center of the guide frame in the X direction, and a Y-axis measuring device to measure the coordinate value of the center of the guide frame in the Y direction. It has a high degree of automation, is less dependent on the technical level of the operator, and has accurate and stable measurement results; the floating platform can drive the bogie to move in the horizontal plane to achieve fine adjustment of the position of the bogie; the power cord of the Y-axis measuring device and the X-axis measuring component can be inserted into the frame through the wire inlet hole and pass through the wire outlet hole, which reduces the external wiring of the equipment, is not easy to cause line damage, and has a beautiful appearance; in this technical solution, the floating platform drives the bogie to move in the horizontal direction through the friction between the floating platform and the bogie, and there is no limiting structure between the floating platform and the bogie, resulting in the possibility of the bogie falling off the floating platform when it is collided, thereby affecting the normal detection of the bogie. For this reason, we propose a bogie alignment detection platform. Utility Model Content

[0004] The utility model aims to provide a bogie alignment detection platform, which solves the problems in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: a bogie alignment detection platform, comprising a frame, a bogie and a horizontal measuring component, the number of the horizontal measuring components is four, the four horizontal measuring components are respectively fixedly mounted at the top of the frame near the four corners, the top of the horizontal measuring component is connected to a floating platform, the bogie is placed on the floating platform, and a limiting mechanism is arranged between the floating platform and the bogie;

[0006] The limit mechanism includes a limit block and a stop plate. The limit block is fixedly mounted on the top of the floating platform. A limit groove is provided on the top of the inner wall of the bogie. The limit block is inserted in the limit groove. The stop plate is fixedly mounted on the outer wall of the limit block, and a limit rod is fixedly mounted on the inner wall of the stop plate. A rod groove is provided on the outer wall of the limit block. The limit rod is inserted in the rod groove. A spring is surrounded by the outer wall of the limit rod. One end of the spring is fixedly mounted on the inner wall of the stop plate, and the other end of the spring is fixedly mounted on the outer wall of the limit block.

[0007] Preferably, the number of the abutment plates is four, and the four abutment plates are respectively arranged on four sides of the limiting block.

[0008] Preferably, the material of the abutment plate is an elastic steel sheet. By selecting the elastic steel sheet as the material of the abutment plate, the abutment plate has a certain buffering effect.

[0009] Preferably, support legs are fixedly installed near the four corners of the bottom end of the frame, and the support legs can provide a good supporting effect on the frame.

[0010] Preferably, mounting grooves are provided on all four sides of the bottom end of the frame, a hydraulic cylinder is fixedly installed on the inner wall of the mounting groove, a support frame is fixedly installed on the output end of the hydraulic cylinder, and a universal wheel is fixedly installed on the bottom end of the support frame.

[0011] Preferably, the number of the universal wheels is four.

[0012] The utility model provides a bogie alignment test platform. The bogie alignment test platform has the following beneficial effects:

[0013] (1) The bogie alignment detection platform can stably drive the bogie to move in the horizontal direction by setting a limit mechanism, and the bogie will not fall off the floating platform when it is hit. The bogie will squeeze the abutment plate and the spring, thereby playing a certain buffering role on the bogie, reducing the impact, and further improving the stability of the bogie. This solves the problem that the floating platform drives the bogie to move in the horizontal direction through the friction between the floating platform and the bogie in the prior art solution, and there is no limit structure between the floating platform and the bogie, resulting in the possibility of the bogie falling off the floating platform when it is hit, thereby affecting the normal detection of the bogie;

[0014] (2) The bogie alignment test platform can make the universal wheel contact with the ground through the cooperation of the support frame, the mounting groove, the hydraulic cylinder and the universal wheel, so that the support legs can be pushed off the ground, thereby making it easier for personnel to push the test platform as a whole to move and carry it, saving manpower and being highly practical.

[0026] The horizontal measuring component 3 is a patented bogie alignment detection platform, with a publication number of CN217930214U, so it is not described and drawn in detail in this article and the accompanying drawings;

[0027] The limiting mechanism 5 includes a limiting block 501 and a stop plate 503. The limiting block 501 is fixedly mounted on the top of the floating platform 4. A limiting groove 502 is provided at the top of the inner wall of the bogie 2. The limiting block 501 is inserted in the limiting groove 502. The stop plate 503 is fixedly mounted on the outer wall of the limiting block 501, and a limiting rod 505 is fixedly mounted on the inner wall of the stop plate 503.

[0028] Specifically, in the above technical scheme, when the bogie 2 alignment detection platform is in use, when the bogie 2 is placed on the floating platform 4, the limit block 501 is inserted into the limit groove 502, so that the abutment plate 503 is in close contact with the inner wall of the limit groove 502.
