Problems solved by technology

The self-weight of the chassis and the mechanical body installed on the chassis cause a great burden on the movement or rotation of the steering wheel
In particular, the construction site is mostly in a rough state, and the ground is mostly undulating and rough, causing great frictional resistance
It is difficult for rolling wheels to achieve linear contact with the ground under actual conditions, and it is especially difficult to turn, resulting in poor mobility and low flexibility of the chassis, which brings great inconvenience to workers' operation and use

Embodiment 1

[0036] see figure 1 , the retractable wheeled chassis 1000 has a chassis body 0100 . The chassis body 0100 serves as a support base for the retractable wheeled chassis 1000 and the construction machinery, plays a load-bearing role, and affects the horizontal state of the construction machinery. Generally, the chassis body 0100 should have sufficient structural strength. The chassis body 0100 can adopt various structural forms, such as a truss structure, an integral casting structure, etc. In this embodiment, the chassis body 0100 adopts a hollow frame structure.

[0037] Please refer to Figure 1~3 , the retractable wheeled chassis 1000 also has a first wheel set 0200, the first wheel set 0200 has a plurality of first moving wheels 0210 arranged axially along the horizontal direction and parallel to each other, and the first moving wheels 0210 are arranged on the chassis body 0100 . The first wheel set 0200 is used to realize the horizontal movement of the retractable whee...

Embodiment 2

[0058] The difference between this embodiment and Embodiment 1 is that in this embodiment, the telescopic moving body 0310 is rotatably held on the chassis body 0100 in the vertical plane.

[0059] Please refer to figure 1 and Image 6 Specifically, one end of the telescopic moving body 0310 is hinged on the chassis body 0100 , and the other end is connected to the second wheel set 0400 . Wherein, the telescopic moving body 0310 is connected with the second moving wheel 0410 in a one-to-one correspondence. Preferably, a motion driving part 0320 is connected to the middle of the telescopic moving body 0310 , and the moving driving part 0320 is used to drive the telescopic moving body 0310 to rotate around the hinged end of the telescopic moving body 0310 and the chassis body 0100 . Among them, the motion driving part 0320 can be in the form of a rotary motor, a linear motor, a cylinder, a hydraulic cylinder, an electric push rod, an electric cylinder, or a hydraulic motor.

Embodiment 3

[0062] The difference between this embodiment and Embodiment 1 is that in this embodiment, the chassis body 0100 is provided with a chassis adjustment mechanism 0500 for adjusting the levelness of the chassis body 0100 .

[0063] Please refer to figure 1 and Figure 7 , specifically, the ground of the construction site is mostly still in a rough state, and has certain ups and downs. If only the plurality of first moving wheels 0210 of the first wheel set 0200 are used to support, the levelness of the chassis body 0100 will be along the ground, resulting in insufficient precision, which in turn will affect the work of the construction machinery working department located on the retractable wheeled chassis 1000 precision. The chassis adjustment mechanism 0500 can independently adjust the levelness of the chassis body 0100, and get rid of the inaccurate levelness of the traditional structure.

[0064] Preferably, the chassis adjustment mechanism 0500 has a plurality of telesco...

Abstract

A telescoping wheel type chassis comprises a chassis body and is further provided with first wheel sets, a telescoping movement assembly and second wheel sets. Each first wheel set is provided with multiple first moving wheels arranged in parallel, the axial direction of each first moving wheel is in the horizontal direction, and the first moving wheels are arranged on the chassis body. The telescoping movement assembly is provided with a telescoping movement body which can linearly move in the vertical direction or be rotationally kept on the chassis body in a vertical face. Each second wheel set is arranged on the telescoping movement body and provided with multiple second moving wheels which are in the horizontal direction, the axial directions of the second moving wheels are arranged in parallel, and the axial directions of the second moving wheels are perpendicular to those of the first moving wheels. The telescoping wheel type chassis has good movement flexibility and the wide processing range.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to a retractable wheeled chassis. Background technique [0002] With the development of the construction industry, the need for construction engineering automation is getting higher and higher. In some miniaturized construction machinery applications, it is often necessary to push the machinery to move or turn. In the current construction machinery, the movement and steering are mainly realized through the chassis structure. [0003] In the existing chassis structure, steering wheels are mostly used for steering or moving. The self-weight of the chassis and the mechanical main body arranged on the chassis cause a great burden on the movement or rotation of the steering wheel. In particular, the construction site is mostly in a rough state, and the ground is mostly undulating and rough, causing great frictional resistance. It is difficult for rolling wheels to achie...
