Problems solved by technology

[0002] The initial support forms of tunnel engineering include sprayed anchor net support and steel frame anchored sprayed support. It is processed in sections in the factory outside the tunnel hole. Before installation, it is transported to the excavation site of the tunnel face. It is manually assembled on the ground into two sections on the left and right, and then assembled vertically. Connect the steel bars, install the steel mesh, and finally, spray the initial support concrete. The existing steel arch installation platform is only for the operators to climb to the installation position on the inner wall of the tunnel, and then manually lift each steel arch section to the installation position. This installation method is labor-intensive and slow, and the working surface of the arch installation is the excavation section just after excavation, the surrounding rock is unstable, and it is easy to cause problems such as falling rocks and injuring people, which is very dangerous. In addition, the existing steel arch support trolley is equipped with traveling wheels and moves through the rails laid in the tunnel. Therefore, the installation process of the steel arch support equipment is greatly increased, and the labor intensity is increased.

Abstract

The invention discloses a movable steel arch bracing trolley comprising a lower stand, an upper support, a plurality of deformable wheels for supporting the lower stand and driving the lower stand to move, and a steel arch jacking system; the steel arch jacking system comprises a jack unit I which is installed between the lower stand and the upper support for jacking the upper support and a jack unit II which is installed on top of the upper support for jacking a steel arch; both the jack unit I and the jack unit II comprise one or more jacks; the deformable wheels of the trolley are able to deform by driving a certain mechanism, so as to greatly increase the trafficability characteristic of the trolley; while traveling on ordinary roads, the deformable wheels can be kept round, allowing a pile driver traveling steadily at a high speed.

Description

technical field [0001] The invention relates to the field of piling equipment, in particular to a movable steel arch support trolley. Background technique [0002] The initial support forms of tunnel engineering include sprayed anchor net support and steel frame anchored sprayed support.
