Abstract

The invention relates to a railway vehicle integral lifting device and a railway vehicle integral lifting method. A traction pin is provided with a lifting base, wherein the lifting base extends towards frameworks at two sides, and is matched with first limiting structures at the frameworks at two sides to form two lifting points in lifting; meanwhile, a traction pull rod and a longitudinal limiting stop catch are matched to form a third lifting point; a vehicle body and a bogie are lifted integrally by the three lifting points. According to the invention, a structure is simplified and optimized by utilizing components such as an existing traction pull rod, so that the integral structure is simple and reasonable; different components are combined to achieve the integral lifting function; the additionally components are less, light weight, low cost and installation convenience can be realized well; moreover, the vehicle body and the bogie can be lifted by three points; the stress is uniform in lifting; stability and reliability can be ensured in lifting, and the phenomena of deviation and the like cannot be generated.

Description

technical field [0001] The invention relates to an overall lifting device for a rail vehicle and a lifting method, belonging to the technical field of rail vehicle manufacturing. Background technique [0002] The rail vehicle is composed of a car body and a bogie. The load between the car body and the bogie is realized by secondary springs, and the traction and braking force is transmitted from the bogie to the car body through the traction rod. China's standard EMUs must be exported overseas, so it is necessary to lift the whole vehicle during sea transportation, and if there is an abnormal situation during the operation of the rail vehicle, and in order to realize the heavy work caused by not lifting the vehicle and pushing out the bogie when replacing the single wheel set Due to the workload, it is often necessary to hoist the car body and the bogie as a whole. [0003] The traditional rail vehicles are equipped with hoisting devices such as lifting holes on the bogie an...
