Automatic walking tunnel trestle capable of steering through rotating shaft as well as method

Abstract

The invention relates to an automatic walking tunnel trestle capable of steering through a rotating shaft, and belongs to the technical field of tunnel construction equipment. The automatic walking tunnel trestle capable of steering through the rotating shaft comprises a back main body, a front walking wheel, and a back walking wheel, wherein the back main body is connected with a front main bodythrough a big rotating shaft device; the front main body and the back main body form an upward inclined surface of a vehicle; the front walking wheel is arranged at the bottom of the front main body;the back walking wheel is arranged at the bottom of the back main body; the big rotating shaft device comprises a convex platform structure and a concave platform structure which are connected througha pin shaft as well as a rotating power mechanism; the convex platform structure is arranged at the connecting end of the back main body; the concave platform structure is arranged at the connectingend of the front main body; the convex platform structure is inserted into the concave platform structure; the pin shaft is inserted in a through hole of a rotating shaft of the convex platform structure and the concave platform structure; and the back main body rotates around the pin shaft and relative to the front main body. The automatic walking tunnel trestle capable of steering through the rotating shaft has the following advantages: a big rotating shaft is arranged on a trestle main body, so that the free steering of the trestle in the use process is realized; furthermore, the automaticwalking tunnel trestle capable of steering through the rotating shaft is convenient to operate, improves equipment flexibility and is easy to popularize.

Description

technical field [0001] The invention relates to a self-propelled tunnel trestle and a method that is steered by a rotating shaft, and belongs to the technical field of tunnel construction equipment. Background technique [0002] The front and rear travel wheels of the original trestle can only walk in a straight line during use. If it is necessary to adjust the steering of the trestle during use, it can only be adjusted separately by repeatedly moving the trestle in the left and right directions in a non-walking state. The walking wheels have height changes in the vertical direction during use, so it is necessary to realize the automatic walking steering of the trestle, and the changes in the vertical and horizontal directions of the trestle must be realized to solve the defects in the prior art. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the existing technology, on the basis of the original trestle, in order t...

Problems solved by technology

[0002] The front and rear travel wheels of the original trestle can only walk in a straight line during use. If it is necessary to adjust the steering of the trestle during use, it can only be adjusted separately by repeatedly moving the trestle in the left and right directions in a non-walking state. The height of the walking wheels in the vertical direction changes during use, so it is necessary to realize the automatic walking and steering of the trestle bridge, and the changes in the vertical and horizontal directions of the trestle bridge must be realized to solve the defects in the prior art
