Abstract

The invention discloses a guide rail device, a scaling ladder mechanism comprising the guide rail device and an overhead working machine. The guide rail device comprises a main body, a guide rail (11), a slide rod (50) and a synchronous driving unit (80); the guide rail (11) is arranged on the main body along the extending direction of the main body; the slide rod (50) is arranged at the bottom of the main body and can be retracted relative to the main body along the length direction of the main body so as to be used as the extension of the guide rail (11); and the slide rod (50) realizes the synchronous retraction through the synchronous driving unit (80). The slide rod can be synchronously retracted so that the sliding distance of a sliding bucket is prolonged after the slide rod stretches out, and a worker can directly slide to the ground from a working bucket.

Description

technical field [0001] The present invention relates to a high-altitude operation machine, in particular to a guide rail device, an aerial ladder mechanism including the guide rail device, and an aerial work machine. Background technique [0002] In aerial work machinery, the aerial ladder mechanism is mainly used for rescue. Specifically, for example, in a fire-fighting aerial ladder vehicle, the aerial ladder mechanism includes an aerial ladder and a working bucket arranged at the top of the aerial ladder. During the rescue, the rescue is carried out through the lifting of the working bucket, for example, the rescued person can enter the working bucket and crawl down the ladder to realize the evacuation of the personnel. Therefore, the rescue time is relatively long, which deviates from the urgency when the disaster occurs, and there is a safety hazard of falling when the rescued personnel climb the ladder. Contents of the invention [0003] The object of the present i...
