Problems solved by technology

[0004] However, the existing engineering vehicle walking chassis frame and supporting legs are separated, and are two independent structures. The supporting legs are completely retracted in the walking state and do not work. The frame is stressed, and the working state is opened to support the force.
To change from the walking state to the working state, the outriggers must be opened and the support fixed; and the outriggers must be retracted from the working state to the walking state, and the process is cumbersome

Embodiment Construction

[0032] The present invention will be further described below in conjunction with examples (accompanying drawings), but does not limit the present invention.

[0033] like figure 1 , 2 As shown, the vehicle chassis described in the present invention includes an intermediate structure 4, and four walking outrigger mechanisms 2 respectively provided with outrigger swing limit locking mechanisms 3 are installed around the intermediate structure 4 in an articulated manner. Between the two walking outrigger mechanisms 2 on the same side of the longitudinal centerline of the intermediate structure 4, there is a detachable outrigger connecting crossbeam 5 for keeping the two walking outrigger mechanisms 2 in a parallel state; the walking outrigger mechanism 2 It includes a walking chassis frame that is hinged to the intermediate structure 4 at one end, and a telescopic outrigger support mechanism 6 that can extend vertically downwards at the other end, and a walking suspension mechan...

Abstract

The invention discloses a traveling vehicle chassis, which is characterized in that the vehicle chassis comprises an intermediate structure (4), and four traveling landing leg mechanisms (2), which are respectively provided with a landing leg swinging limited locking mechanism (3), are mounted around the intermediate structure (4) in a manner of hinge joint, wherein a detachable landing leg connection cross beam (5) for keeping two traveling landing leg mechanisms (2)at the same side of a longitudinal center line of the intermediate structure (4) balance is arranged between the two traveling landing leg mechanisms (2).

Description

technical field [0001] The invention relates to a walking equipment, in particular to a walking vehicle chassis. [0002] Background technique [0003] In recent years, with the development of social production and the rapid development of large-scale construction projects, the demand for transportation and equipment construction machinery is also increasing, and the requirements are also getting higher and higher. In particular, the road conditions at the construction sites of many large-scale projects are harsh, and there is an urgent need for transportation and equipment construction machinery with strong walking ability, flexibility, and portability. [0004] However, the existing engineering vehicle walking chassis frame and supporting legs are separated, and are two independent structures. The supporting legs are completely retracted in the walking state and do not work. The frame is stressed, and the working state is opened to support the force . To switch from...
