Novel multi-functional operation trolley used for tunnel construction

Abstract

The invention discloses a novel multi-functional operation trolley used for tunnel construction. The operation trolley includes a chassis, a caterpillar band and a power device; the lower portion of the chassis is provided with the caterpillar band, the upper portion of the front part of the chassis is provided with the power device, the rear portion of the chassis is provided with retractable support legs, the middle of the upper portion of the chassis is provided with a middle working arm, the left side and right side of the chassis are symmetrically provided with a left-side working arm and a right-side working arm respectively, the top of the middle working arm is provided with a main hanging basket, and the top of the left-side working arm and the top of the right-side working arm are provided with side hanging baskets arranged in a symmetrical mode respectively. The multi-functional operation trolley is mainly used for primary support, explosive material filling and other kinds of high-altitude operation and construction of tunnel excavation of high-speed railways, light rails, subways and the like, and mainly devoted to solving the problems occurring in all primary support, explosive material filling and other kinds of high-altitude operation in the tunnel construction, the operation includes back break and dangerous rock processing of a tunnel face, installation of a steel arch and erecting of a reinforcing mesh, and at the same time, other kinds of high-altitude operation and hoisting operation in the tunnel can also be completed.

Description

technical field [0001] The invention relates to a multifunctional operation trolley, in particular to a novel multifunctional operation trolley for tunnel construction, and belongs to the technical field of construction machinery. Background technique [0002] At present, high-altitude operations such as over- and under-excavation and dangerous rock treatment, steel arch installation, steel mesh hanging, and explosive loading in tunnel construction mainly rely on manual construction, and simple steel structures or equipment are used to carry out the work. Auxiliary construction. These manual-based tunnel constructions with high-altitude operations are characterized by intensive personnel, high labor intensity, low efficiency, and high safety risks. Once a safety accident occurs, the loss will be very large and the impact will be severe. In recent years, with the continuous attention to mechanized construction, some specialized equipment for the above-mentioned single constr...

Problems solved by technology

These manual-based tunnel constructions with high-altitude operations are characterized by intensive personnel, high labor intensity, low efficiency, and high safety risks. Once a safety accident occurs, the loss will be very large and the impact will be bad.

In recent years, with the continuous attention to mechanized construction, some specialized equipment for the above-mentioned single construction operations have also appeared one after another, but they all have a common feature: they only pay attention to a certain construction link, while ignoring related work links. Multiple links have been considered, but the structure of the equipment is too complicated, inconvenient to use, and the cost is very high
