Description

Technical Field

[0001] The utility model relates to the technical field of locomotive maintenance, and particularly relates to a replacement positioning device for a locomotive brake caliper seat. Background Art

[0002] Harmony D3 series locomotives are the main line passenger and freight electric locomotives in China's railway. Their braking methods all adopt disc brakes, that is, corresponding brake calipers are installed on the left and right of each pair of wheels to restrict the frictional force generated in the circumferential direction of the wheels when the locomotive brakes. In order to facilitate the fixation of the brake calipers, a mounting seat is usually used for installation and fixation.

[0003] For example: The utility model with the application number CN201620011595.5 discloses a motor car bogie frame. Specifically, the utility model provides a motor car bogie frame, which includes two side beams in a box structure and two cross beams fixedly connected to the two side beams. The cross beams are in a hollow structure, a longitudinal beam is fixed between the inner sides of the two cross beams, and brake hanging seats are fixed at both ends of each side beam. The brake hanging seats and the upper cover plates of the side beams form a closed box structure. The power bogie frame provided by the utility model has a simple structure. On the premise of ensuring the strength of the frame, it can meet the requirements of vehicle body lightweight, and at the same time, realize the three-point hanging installation of the brake calipers.

[0004] However, for the current traditional brake caliper mounting seat, when replacing the brake caliper mounting seat with fatigue cracks, usually the cracked mounting seat is first gas-welded and cut, the bottom surface of the frame is ground and repaired, and then the mounting seat is welded for repair. However, in the actual operation process, due to the relatively compact structure of the locomotive and limited by space, during the measurement and marking process, the reference and dimensions will have large errors, resulting in inaccurate position of the mounting seat after welding, large deviation of the brake caliper after installation, and phenomena such as uneven wheel wear and uneven braking force, which is a potential quality hazard for the subsequent operation of the locomotive. Content of the Utility Model

[0005] In view of this, the utility model provides a replacement positioning device for a locomotive brake caliper seat, which has a connecting beam plate, a first positioning plate and a second positioning plate that can accurately position the brake caliper mounting seat. When replacing one mounting seat, the first positioning holes and second positioning holes in other positions are fastened to the other three mounting seats through the first fixing pins or the second fixing pins. After being fixed, the naturally formed position can just position the mounting seat to be replaced. Subsequently, the mounting seat to be replaced is fastened to the first positioning holes or the second positioning holes through the first fixing pins or the second fixing pins, so as to accurately fix the position of the mounting seat and facilitate the subsequent welding of the mounting seat.
