Embodiment Construction

[0022] The present invention will be described in detail below in combination with specific embodiments.

[0023] The invention relates to a bogie lifting and rim weighing composite track structure, which includes a weighing rail 2 on the inner side of the track rail centerline and a bogie lifting beam 1 on the outer side, both of which are longitudinally arranged, and the bogie lifting beam 1 is at the lowest position At the end, the vehicle wheel load is completely carried by the weighing rail 2, and when the vehicle wheel passes, the wheel tread does not contact the bogie lifting beam 1; there is a gap between the weighing rail 2 and the bogie lifting beam 1 in the transverse direction, and they are independent of each other. The up and down movement of the lifting beam 1 does not interfere with the weighing rail 2, so that the lifting of the vehicle bogie and the weighing of the vehicle can be completed on a section of track.

[0024] The weighing rail 2 is provided with a...

Abstract

The invention relates to a bogie lifting and rim weighing composite track structure, which comprises weighing rails on the inner side of the central line of a track steel rail and bogie lifting beamson the outer side of the central line of the track steel rail, wherein the weighing rails and the bogie lifting beams are longitudinally arranged, and vehicle wheel loads are completely borne by the weighing rails when the bogie lifting beams are positioned at the lowest ends; the weighing rails and the bogie lifting beams are transversely provided with gaps. The invention solves the problem thatthe lifting beams and the weighing rails of the bogie of a car lifting jack cannot be arranged on the same section of track side by side, the pit car lifting jack with the structure device can be integrated with a single car weighing platform, and the car can be weighed and adjusted without moving the car after the operation is finished, so that the occupied area is reduced, the transportation ofthe car is reduced, the operation time is saved, and the new construction and overhaul operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of new manufacturing or maintenance of rail transit vehicles, in particular to a composite track structure for bogie lifting and rim weighing. Background technique [0002] Existing newly built or advanced repair rail transit vehicles are manually pushed or pulled by tractors to the single vehicle weighing station after the installation of the frame is completed at the completion station. At the completion station, the lifting beam of the vehicle bogie is lifted by the lifting beam of the pit crane to lift the vehicle tread, while at the single vehicle weighing station, the vehicle contacts the weighing rail through the wheel tread, and the load of the wheel is weighed. The weighing sensor of the rail is converted into an electrical signal and transmitted to the signal acquisition and processing system. Both devices support the vehicle body through the bogie wheel treads, and the lifting beam and weighing r...
