Abstract

The invention discloses a foldable escalator, which comprises a pedal hinged on the escalator box through a main hinge shaft, one of the multiple pedals is the main pedal, and the main hinge shaft on the main pedal is provided with teeth through a gear plate reset spring sleeve. There is a knife plate on the inner side of the main hinge shaft, and the knife plate is hinged on the main pedal near the tooth plate through the knife plate return spring sleeved on the first pin shaft; the knife plate has a ratchet that is movable and engaged with the tooth plate The claw part and the rocker part extending out of the main pedal, the main pedal is provided with a first limit pin at the outer edge connecting the ratchet part and the rocker part; the escalator box is provided with a driving handle part below the rocker part The rotating cam is provided with a second limit pin near the cam, and a second limit pin is arranged below the first limit pin; each connecting plate is provided with a plurality of The arc-shaped opening of the main hinge shaft is clamped. Compared with the prior art, the present invention can solve the problem that the escalator of the existing engineering machinery vehicle is easily deformed and damaged by collision when turning in a narrow space.

Description

technical field [0001] The invention relates to the technical field of manufacturing engineering machinery vehicles, in particular to a folding escalator for engineering machinery vehicles. Background technique [0002] The escalator on the driver's cab of the existing construction machinery vehicle all comprises an escalator box and a plurality of pedals, and the plurality of pedals are fixedly mounted on the escalator box; the escalator box is installed on the vehicle frame near the cab door. . This kind of escalator has the following problems during use: because the escalator is on the outermost side of the turning vehicle, when the vehicle is turning in a narrow space, it is easy to be deformed and damaged by bumps; The raised sludge is splashed on the escalator, and the sludge accumulates, which affects the driver's access to and from the cab. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a folding escal...
