Embodiment Construction

[0020] refer to figure 1 - Figure 5 , the specific embodiment of the present invention includes the main body of the obstacle remover 1, the honeycomb energy-absorbing unit 2, the mounting seat 3, and the safety hanger 4. The obstacle removal surface at the front of the obstacle remover adopts a figure-eight shape with an included angle of 156°, which is convenient for pushing obstacles out of the track scope. In the middle of the main body of the obstacle remover is a honeycomb groove 101 with a front opening, and two upper and lower sliding rails 102 are arranged on both sides of the honeycomb groove. The front end of the honeycomb 201 is connected to the front cover to form 204, and the rear end passes through the main body 1 of the obstacle remover. fall off. The side of the front cover plate is processed with slide grooves 202 matched with the slide rails 102 on the honeycomb grooves, which have a guiding effect on the energy absorption of the honeycombs. So far, the...

Abstract

The invention discloses a cowcatcher with a drawer type honeycomb energy absorption structure. The cowcatcher comprises a cowcatcher main body, a honeycomb energy absorption unit and a mounting seat.A honeycomb groove with an opening in the front is formed in the middle of the cowcatcher main body, the honeycomb groove is in sliding fit with the honeycomb energy absorption unit to form a drawer type structure, and when an inner portion of a center area of the cowcatcher is seriously impacted, a front cover plate assembly retreats along a sliding rail, honeycombs are compressed, impact energyis effectively absorbed and a rear supporting frame structure and a vehicle body structure are protected from damage. The cowcatcher is simple in structure, and a current situation that an overall size is large due to a fact that an energy absorption honeycomb of an existing cowcatcher is arranged in front of a front baffle is changed. The cowcatcher is convenient to maintain, the energy absorption unit can be independently replaced by detaching the front cover plate, overall detachment is not needed, and the cowcatcher is almost free of maintenance in normal use.

Description

technical field [0001] The invention relates to an obstacle remover technology for a rail vehicle, in particular to a drawer-type honeycomb energy-absorbing obstacle remover. Background technique [0002] my country's urban rail vehicles have just started, and there are few researches and applications on the obstacle remover. Therefore, there are deficiencies in the design concept of the obstacle remover and the cognition of related standards. At present, rail vehicles in foreign cities are widely used, and the models are generally equipped with obstacle removers, most of which are rigid obstacle removers, which cannot alleviate the impact energy of hitting obstacles, causing damage to the car body at the installation interface, and the volume is large, and the cost of maintenance and replacement is relatively high. high. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the rigid obstacle remover cannot alleviate the imp...
