Aluminum honeycomb type energy absorption obstacle remover used for urban rail train

Abstract

The invention provides an aluminum honeycomb type energy absorption obstacle remover used for an urban rail train and belongs to the field of obstacle removing mechanisms on the lower portions of railway vehicle heads. The obstacle remover comprises a supporting frame, a left energy absorption unit and a right energy absorption unit. The supporting frame comprises a supporting frame front end plate, a front end plate rear side rib plate supports and two connecting seats. The largest energy absorption stroke of aluminum honeycomb energy absorption plates adopted by the two energy absorption units of the obstacle remover is 120 mm, the resistant force of the aluminum honeycomb energy absorption plates is 165+ / -10% kN, and the energy absorption capacity is about 20 kJ. Therefore, the energy absorption obstacle remover can meet the requirement for the effective energy absorption and train body protection parameter needed when the train hits an animal weighing 120 kg at most at the speed level of 160 km / h.

Description

technical field [0001] The invention belongs to the field of obstacle removal mechanism at the lower part of the rail vehicle head, and in particular relates to an aluminum honeycomb energy-absorbing obstacle removal device used for urban rail trains. Background technique [0002] At present, the obstacle deflectors installed on rail vehicles in foreign cities are usually those with hydraulic elastic energy-absorbing buffer structures or crushing energy-absorbing buffer structures. The design of the obstacle deflectors is complex and the production cost is high. [0003] my country's urban rail vehicles have just started, and the original relatively closed subway lines have no demand for obstacle removers. Therefore, there are insufficient cognitions on the design concept of obstacle removers and related standards. In order to push the obstacles away from the track to both sides, the obstacle remover is usually set in a figure-eight symmetrical structure, and the included an...

Problems solved by technology

[0005] In order to solve the left-right symmetrical structure of the figure-eight shape of the existing obstacle remover, there is no uniform design standard for the obstacle removal angle of the figure-eight-shaped obstacle remover, and the front end of the existing obstacle remover is usually a single vertical plate, a slope plate or arc plate structure, and the unreasonable design of the obstacle removal angle, the slope angle of the front end plate or the radian value will seriously affect the impact strength and service life of the obstacle remover, and the existing hydraulic elastic energy-absorbing buffer or compression The design of the obstacle remover of the energy-absorbing buffer structure is complicated and the production cost is high. Therefore, there is currently a lack of a new type of obstacle remover that is suitable for the installation interface of domestic urban rail vehicles with a speed of 160km / h, and is easy to maintain, beautiful and economical. The technical problem of the device, the present invention provides an aluminum honeycomb energy-absorbing obstacle remover for urban rail trains
