Abstract

The invention provides a mixer truck and a crawling ladder device thereof. The crawling ladder device comprises a main ladder and an auxiliary ladder. The main ladder comprises two supporting beams arranged in parallel and at intervals and a connecting beam connected between the bottoms of the two supporting beams, and the two supporting beams are provided with rails extending vertically. The auxiliary ladder comprises an auxiliary ladder main body, slip assemblies symmetrically arranged on the two sides of the auxiliary ladder main body and turnover brackets symmetrically arranged on the twosides of the main ladder, the two slip assemblies are in sliding fit with the two rails correspondingly so that the auxiliary ladder can slide upward to be accommodated in the main ladder or stretch downward out of the main ladder, one end of each turnover bracket is hinged to one side of the middle area of the auxiliary ladder main body, and the other end of each turnover bracket is hinged to thecorresponding slip assembly. When the slip assemblies slide upward, the turnover brackets are turned from the horizontal position to the vertical position, the auxiliary ladder slides upward to be stored in the main ladder; and when the slip assemblies slide downward, the turnover brackets are rotated from the vertical position to the horizontal position, the auxiliary ladder stretches downward out of the main ladder, and the turnover brackets abut against the connecting beam.

Description

technical field [0001] The invention relates to the field of transport vehicles, in particular to a mixer truck and a ladder climbing device thereof. Background technique [0002] A mixer truck is a special vehicle widely used in the engineering and construction industry for carrying mixed concrete. There is usually a ladder on the mixer truck for the staff to go up and down, so as to wash, inspect, and maintain the roof of the mixer truck such as the feed inlet and hopper. [0003] At present, the climbing ladder is fixed on the frame of the mixer truck, and its bottom end is usually located at the frame, so that the bottom of the climbing ladder is higher than the ground, and it takes time and effort for the staff to go up and down. Contents of the invention [0004] The object of the present invention is to provide a mixer truck which is convenient for climbing up and down and its ladder climbing device, so as to solve the problems in the prior art. [0005] In order ...
