A climbing ladder and a road sweeper with the same

Abstract

The invention discloses a ladder stand which comprises an upper ladder stand body and a lower ladder stand which are independent. The lower ladder stand body is in sliding connection with the lower end of the upper ladder stand body. A hinge seat mechanism, a limiting mechanism and a rotary shaft are further included, the hinge seat mechanism comprises a first shaft hole, a second shaft hole and a third shaft hole which are coaxially formed, a first sleeve and a second sleeve are coaxially arranged on the two sides of the upper end face of the upper ladder stand body respectively, and the rotary shaft sequentially penetrates through the first shaft hole, the first sleeve, the second shaft hole, the second sleeve and the third shaft hole to rotationally connect the upper ladder stand body to the hinge seat mechanism. The portion, between the second shaft hole and the second sleeve, of the rotary shaft is sleeved with a spring for pressing the upper ladder stand body to the third shaft hole, the limiting mechanism comprises at least one first limiting part and at least one pair of second limiting parts, a first clamping groove for limiting and fixing the upper ladder stand body and the lower ladder stand body is formed in the position, corresponding to the lower ladder stand storing and placing position, of the first limiting part, and second clamping grooves for limiting and supporting the upper ladder stand body are formed in the positions, corresponding to lower ladder stand body and sliding to the use position, of the second limiting parts. The invention further provides a road sweeper with the ladder stand.

Description

technical field [0001] The invention relates to a climbing ladder and a road cleaning vehicle with the climbing ladder. Background technique [0002] Currently used trucks or special vehicles, due to the need for unloading or loading, there is an unloading ladder at the rear of the compartment for people to go up and down. The upper end of the ladder is usually directly welded or installed with the rear of the compartment, which cannot realize hidden storage, which not only affects the appearance. And be unfavorable for the long-term preservation of climbing ladder; And existing road sweeping vehicle, its compartment tail is not provided with the climbing ladder that can climb so that observe compartment interior situation for the staff mostly. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, to provide a climbing ladder with reasonable design, simple structure, easy storage and use, good practicability...
