Explosion-proof trackless rubber-tyred vehicle with inverted arch block stable supporting function

Abstract

The anti-explosion trackless rubber-tyred vehicle with the inverted arch block stable supporting function comprises a driving part, a steering part, a power part and a supporting part, at least two supporting pieces for supporting inverted arch blocks are arranged on the top face of the supporting part, and rotating body spherical hinge mechanisms are arranged at the rotating ends of the supporting pieces to form driving structures for the supporting pieces to swing horizontally. The swivel spherical hinge mechanism drives the supporting piece to be switched to be in a transverse supporting state or a longitudinal supporting state. On one hand, the swivel spherical hinge mechanism is adopted, stable and high-precision angle adjustment of the supporting piece is achieved, supporting of the supporting piece is stable, meanwhile, the supporting piece suitable for transverse supporting such as an inverted arch block can be supported in the transverse supporting state, and the supporting piece suitable for longitudinal supporting such as a concrete tank body can be supported in the longitudinal supporting state; therefore, the supportable supporting range of the supporting part is expanded.

Description

technical field [0001] The invention relates to the technical field of an explosion-proof trackless rubber-tyred vehicle, in particular to an explosion-proof trackless rubber-tyred vehicle with a stable support function of an inverted arch block. Background technique [0002] The prototype of the explosion-proof trackless rubber wheeled vehicle is a segment transport vehicle. The segment transporter is mainly used to transport segments (inverted arch segments) for shield tunnel construction. The most common one is that in subway construction, the shield machine needs to continuously splicing segments during tunnelling, but segment splicing The distance between the storage positions of the outer segments of the tunnel is usually very long, and the space in the tunnel roadway, especially at the rear and inside, is relatively narrow. [0003] The swivel spherical hinge, as the axis of the swivel construction technology, is the core component to realize the high-precision swive...

AI Technical Summary

Problems solved by technology

[0005] One: Most of the supports of the inverted arch block in the existing support part are rigidly connected with the frame assembly, and the angle of the support cannot be adjusted. On the one hand, the contact effect between the inverted arch block and the top surface of the support is limited, thereby limiting the inversion. The supporting effect of the block; on the other hand, the supporting range is limited and can only be used to support the inverted arch block
