Description

Technical Field

[0001] This utility model relates to the field of bogie fixing fixture technology, specifically a fixing fixture for locomotive and rolling stock bogies. Background Technology

[0002] A locomotive bogie is an independent running gear consisting of two or more pairs of wheelsets connected by a frame or other device, capable of rotating relative to the car body, and equipped with springs and other components. Depending on the vehicle's total weight, the car body is supported on two or more bogies. Generally, the running gear of a vehicle consists of two two-axle bogies, while a few vehicles use three-axle bogies, and some long freight cars consist of four, six, or eight bogies. The more axles, the greater the vehicle's load capacity. During assembly, the bogies are assembled using fixed fixtures to ensure driving safety and improve vehicle stability.

[0003] Currently, when using fixed fixtures to fix and adjust bogies for locomotives and rolling stock, the process is cumbersome and inefficient for different specifications of locomotives and rolling stock. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing fixture for locomotive and rolling stock bogies, thereby solving the problem mentioned in the background art that current fixing fixtures are cumbersome to use for fixing and adjusting locomotive and rolling stock bogies of different specifications, resulting in low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for a locomotive bogie, comprising a base, two first fixing brackets fixedly mounted on the outer surface of the base, a first sliding groove formed on the outer surface of the first fixing bracket, a first servo motor embedded inside the first fixing bracket, a first gear plate fixedly mounted at the output end of the first servo motor, a first rack plate and a second rack plate meshing with the outer surface of the first rack plate, a second fixing bracket fixedly connected to the outer surfaces of both the first and second rack plates through the first sliding groove, a second sliding groove formed on the outer surface of the second fixing bracket, a second servo motor embedded inside the second fixing bracket, a second gear plate fixedly mounted at the output end of the second servo motor, two connecting rack plates meshing with the outer surface of the second gear plate, and connecting brackets fixedly connected to the outer surfaces of both connecting rack plates through the second sliding groove.

[0006] Preferably, each of the four connecting frames is provided with a drive motor on its outer surface, and a long screw is fixedly installed at the output end of the drive motor. The long screw is rotatably connected to the connecting frame. Each of the four connecting frames has a limit opening on its outer surface, and each of the four long screws has a fixing member slidably connected to its outer surface through the limit opening.

[0007] Preferably, the outer surface of the base is embedded with a main electric telescopic seat and four auxiliary electric telescopic seats, and the main electric telescopic seat is located at the center point of the base, while the four auxiliary electric telescopic seats are arranged in a rectangular array.

[0008] Preferably, a mounting base is fixedly installed on the outer surface of the base, and a plurality of mounting holes are opened on the outer surface of the mounting base. A controller is provided on the outside of the base, and the controller is electrically connected to a first servo motor, a second servo motor, a drive motor, a main electric telescopic seat, and an auxiliary electric telescopic seat.

[0009] Preferably, the two first fixing frames and the two second fixing frames form a rectangle, and the two first fixing frames are arranged in parallel, the two second fixing frames are arranged in parallel, and the first fixing frames and the second fixing frames are arranged at an angle of 90 degrees.

[0010] Preferably, all four fixing members are fitted and connected to the outer surface of the base, and the fixing members are located at the intersection of the first fixing frame and the second fixing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The bogie fixing fixture of this locomotive and rolling stock uses two No. 1 servo motors to drive the No. 1 rack plate and the No. 2 rack plate to move in opposite directions, thereby driving the two No. 2 fixing brackets to move closer or further apart. At the same time, the two No. 2 servo motors are controlled to drive the two connecting rack plates to move closer or further apart, so that the four fixing components can be used according to the specifications of the locomotive and rolling stock bogie. This achieves the effect of facilitating the fixing and adjustment of locomotives and rolling stock of different specifications and improving the efficiency of use.

[0013] 2. The bogie of this locomotive uses a fixed fixture. By controlling four drive motors to operate synchronously, the long screw is rotated, which in turn drives four fixed parts to slide up or down on the outer surface of the long screw through the limit port. This allows the fixed locomotive bogie to be raised or lowered, thus achieving the effect of easy height adjustment and easy operation. Attached Figure Description
