Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for testing suspended monorail vehicles, specifically to a running-in test bench for a suspended monorail vehicle bogie. Background Technology

[0002] Suspended monorail vehicles are a new type of rail transit vehicle whose car body is suspended below a box girder track beam and achieves its carrying function through a bogie system connected to the top of the car body. The bogie, as a crucial component of the vehicle, plays a vital role, bearing the traction, transmission, and braking functions of the entire vehicle. Before a vehicle is officially put into operation, a system is needed to conduct a run-in test of the bogie system to verify the reliability of its traction, transmission, and braking functions. Currently, only traditional wheel-rail trains in the rail transit industry have dedicated bogie run-in test benches; there are no dedicated run-in test benches for suspended monorail vehicle bogies. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects in the prior art and provide a running-in test bench for suspended monorail vehicle bogies, which fills the gap in the prior art, solves the problems of inconvenience in running-in testing of suspended monorail vehicle bogies, greatly increases the difficulty of operation for operators, and results in low testing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a suspended monorail vehicle bogie running-in test bench, comprising a support frame, a support platform, running-in wheel sets, guide wheel stop assemblies, and a loading assembly. The support frame is composed of I-beams, connected by bolts to form a frame structure including a rectangular frame at the bottom and four column structures at the intersection of the rectangular frames. The columns of the support frame are aligned with the bogie running wheels, serving as the main load-bearing components. The support platform includes a flat plate, bottom reinforcing I-beams, and channel steel. The flat plate is a hollow structure to accommodate the placement of the suspended vehicle bogie. Left and right channel steels are welded to the upper surface of the flat plate as mounting seats for the running-in wheel sets. Mounting holes for the guide wheel stop assemblies are reserved at the ends and middle of the flat plate. Bottom reinforcing I-beams are welded to the lower surface of the flat plate. The running-in wheel sets... The set consists of 4 sets, installed between the channel steels of the support platform. Each set of running-in wheel assembly comprises 6 rolling wheels, including bearings and running-in wheels capable of high-speed rotation along the axis. The width and length of each set of running-in wheel assembly meet the size requirements of the bogie running wheels, realizing the rotation requirements of the running wheels. The guide wheel stop assembly includes a guide wheel stop and a lateral positioning stop. The guide wheel stop assembly is fixedly installed on the flat plate of the support platform by bolts, wherein the guide wheel stop is located on the outside of the running-in wheel assembly, and the lateral positioning stop is located on the inside of the running-in wheel assembly. The loading assembly includes a loading beam bolted to the column, a loading rod installed on the loading beam, and a loading spring connected to the lower end of the loading rod. The upper part of the loading rod is connected to the bogie components, and the loading force is adjusted by adjusting the height of the loading spring.

[0005] Further optimization involves installing an angle steel structure between the columns of the supporting frame and the rectangular frame.

[0006] Further optimization involves the guide wheel stop and the lateral positioning stop having the same structure, including a bottom connecting plate, a support rod fixed to the connecting plate, and a threaded post horizontally connected to the support rod via threads.

The threaded post of the guide wheel stop is aligned with the length direction of the flat plate, and the top plate faces the center. The threaded post of the lateral positioning stop is aligned with the width direction of the flat plate, and the top plate faces the center. The guide wheel stop adjusts the distance between the top plate and the guide wheel by bolting the post, so that the guide wheel is fully pressed, thus achieving longitudinal fixation of the bogie. The lateral positioning stop achieves lateral fixation of the bogie.

[0007] Further optimization involves making the loading crossbeam a detachable structure, which facilitates the installation of the bogie.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: The device adopts a modular and lightweight design, realizes the placement of the entire bogie structure, realizes load loading, has the function of guide wheel positioning, and can carry out traction and its transmission system running-in.
