Problems solved by technology

In the streamlined locomotive newly developed in China, the movable hood is connected to the fixed hood by manual means such as bolts. During shunting operation or after operation, the movable hood can only be unloaded and installed manually, which is time-consuming and inconvenient. It is also easy to cause damage to the movable hood

Abstract

An automatic opening-closing unit for the movable head cover of locomotive with stream line contour is composed of fixed head cover, movable head cover, supporting mechanism, slide mechanism, pilot mechanism, link-rod unit, drive unit and the switching unit between manual and electric operations. Under the action of pilot mechanism, the link-rod, slide and supporting units and the movable head cover are sequentially driven by drive unit to move the movable head cover directionally to inside of fixed head cover or to original position for closing it. Said movable head cover can also be opened or closed manually when electric power is turned off.

Description

Technical field: [0001] The invention relates to a device for closing and opening a locomotive head cover, in particular to a movable head cover closing and opening device for locomotives such as high-speed locomotives and power cars with a streamlined shape. Background technique: [0002] In the past, due to the low speed of locomotives produced and used at home and abroad, the shape of the driver's cab at the head of the locomotive was mostly square in the early days, and the couplers used for shunting operations were also exposed outside the car body. Therefore, the shunting operations of locomotives were not protected. hinder. With the continuous improvement of the running speed of the locomotive, the shape of the locomotive head has been changed to a streamlined shape due to the need to reduce air resistance and aesthetics, and the couplers for shunting operations are also placed in the locomotive head cover, which hinders daily adjustment. Car work. For solving this ...
