Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with specific embodiments.

[0026] The invention relates to a device compatible with multi-type EMU bogie lifting and wheel flange weighing operations, compatible with multiple types of EMU bogies, and capable of completing the lifting and weighing of single EMU vehicles at the same station operation.

[0027] The specific structure is: a weighing rail 2 is installed on the inner side of the center line of the rail, and a longitudinal bogie lifting beam 1 is installed on the outer side, both of which are arranged longitudinally. When the bogie lifting beam 1 is at the lowest end, the vehicle wheel load is completely carried by the weighing rail 2 , And when the vehicle wheels pass, the wheel tread does not contact the bogie lifting beam 1; a set of bogie lifting beams 1 and weighing rails 2 are set at the four wheels of each bogie, the length and interval of each group Different, meet the different fixe...

Abstract

The invention relates to equipment compatible with multi-type motor train unit bogie lift and rim weighing work. A weighing rail is arranged in an inner side of a center line of a track rail, and a longitudinal bogie lift beam is arranged on an outer side, and the two are longitudinally arranged. When the bogie lift beam is at the lowest end, a vehicle wheel load is completely carried by the weighing rail. One group of the bogie lift beams and the weighing rail are arranged at four vehicle wheels of each bogie. Lengths and front-to-back spacings of each group are different, and different distances and wheel bases of a single section vehicle bogie of CRH2, CRH3, CRH5, CRH380A, CRH380B, CR400A, and CR400B series of motor train units are satisfied.

Description

Technical field [0001] The invention relates to the technical field of new construction or maintenance of rail transit vehicles, in particular to a device compatible with multi-type EMU bogie lifting and wheel rim weighing operations. Background technique [0002] my country’s existing production lines for newly-built or overhauled EMU bogies are designed for bogie lifting and car body weighing equipment. Two support beams carry the wheels on both sides of the bogie. Because of different types of EMU bogies , The wheelbase and fixed distance are not exactly the same (see Table 1), and if the support beam is too long, it will inevitably reduce its stiffness, increase deformation, and affect equipment accuracy. Therefore, the same lifting and weighing equipment can only correspond to one One or several EMU bogies with close dimensions. [0003] [0004] The lifting of the bogie and the weighing of the car body require the track to support the wheels of the bogie, and the lifting is us...
