Rotary table of arch installation machine for tunnel

Abstract

The invention discloses a rotary table of an arch installation machine for a tunnel. The rotary table comprises a chassis, a cab 2, a traveling mechanism 3, an upper platform 4, a working arm 5 and a working device 6. The rotary table is characterized in that a rotary platform 45 comprises a bottom plate 451, a cab rotary base 452, two installation arm bases 453 and a hanging basket arm rotary base 454, wherein the bottom plate is used for supporting all assemblies on an installation platform, the cab rotary base is arranged on the front left, the two installation arm bases and the hanging basket arm rotary base are arranged on the front right of the bottom plate and located on the right side of the cab rotary base, and the two installation arms are symmetrically installed relative to a hanging basket arm.

Description

technical field [0001] The invention relates to a turntable of an arch installation machine, in particular to a turntable of an arch installation machine for tunnels, and belongs to the field of manipulators. Background technique [0002] In recent years, with the rapid development of my country's economy, the construction of my country's transportation infrastructure is also developing rapidly, especially in the construction of expressways and railways, which put forward new requirements and tests for the mechanization level of tunnel construction in my country. Especially in the tunnel construction of soft surrounding rock, the installation of the supporting steel arch after excavation is particularly critical. But in the current stage of domestic tunnel construction, the installation of steel arches is still mainly done manually or with the help of other equipment. Not only is the labor intensity relatively high, but also the efficiency and safety cannot be guaranteed. I...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a turntable of an arch installation machine for tunnels, and the steel arch installation machine for tunnels with double installation arms and a swivel support can be used to solve the problem of steel arch installation for tunnels in the prior art. Frame installation machine turntable The working arm used for steel arch installation only includes one installation arm and one hanging basket arm. The hanging basket arm does not have a slewing support. Only one section of steel arch can be installed at a time, which is not convenient for the overall installation. Adjustment, and the cab is generally arranged between the installation arm and the basket arm, which is not convenient for driving and operation. In actual installation, the working accuracy and efficiency will not be improved, and at the same time, the difficulty of installation will increase.
