Description

Technical Field

[0001] The invention relates to a portable railway locomotive vehicle coupler center height measuring device and method. Background Art

[0002] The continuous development of my country's railway transportation has provided favorable conditions for the country's economic growth. At the same time, with the increase in train speed and freight load capacity, extremely high requirements have been put forward for the maintenance of trains before operation. The coupler is a connecting component between the train head and the carriage or between the carriages, which plays the role of train traction, operation buffer and stability. The accurate measurement of the center height of the coupler of the locomotive and vehicle is closely related to the safety of the vehicle. The maintenance before the train operation requires the guarantee of anti-slip, anti-jump, smooth and safe operation of the coupler. If the center height of the coupler is not set properly, it may cause the connection between the locomotive and the carriage to be loose, resulting in a decoupling accident. Therefore, by accurately measuring the center height of the coupler of the locomotive and vehicle, the reliability and stability of the coupler connection can be ensured, and the safety of railway transportation can be improved.

[0003] At present, the coupler height measurement tool used by China Railway is a T-shaped measuring ruler, which has several shortcomings in the measurement process:

[0004] 1) The measuring ruler is large in size, which is not convenient to carry, and it is not convenient to move the measuring ruler during single-person operation;

[0005] 2) It is necessary to read the measurement value on the scale line of the measuring ruler. This process does not directly and clearly present the measurement value, which leads to low efficiency and prone to errors;

[0006] 3) During operation, place the horizontal ruler of the measuring ruler horizontally on the rail surface, and stand the vertical ruler against the hook so that it is perpendicular to the rail surface, and slide the caliper to measure the height. This measurement method is inconvenient to operate;

[0007] 4) The measuring claws cannot be adjusted. Most locomotive and vehicle coupler center height measuring rulers can only measure the locomotive and vehicle couplers of specific models and are not universal.

[0008] 5) During the measurement process, the ruler body cannot move horizontally. Multiple measurements require the ruler base to be moved back and forth, which is not practical. Summary of the invention

[0009] In order to solve the problems existing in the above-mentioned background technology, the present invention proposes a portable railway locomotive vehicle coupler center height measuring device, which has the advantages of good portability, low operation difficulty, high work efficiency, accurate measurement results, good practicality, low cost and wide application range.

[0010] The technical solution of the present invention to solve the above problems is:

[0021] Furthermore, the laser measurer is provided with a laser measurer emission port, a laser measurer charging port, a laser measurer start button and a laser measurer display screen, and the laser measurer emission port is located opposite to the laser passage hole.

[0022] As a further technical solution, the shell material of the centering clamping and positioning mechanism and the shell of the measuring device fixing device are ABS plastic, which has the advantages of glossy texture, drop resistance, wear resistance and not easy to deform, and can be well adapted to the working environment of the measuring device.
