Abstract

The invention discloses a multi-functional tunnel operation trolley, which comprises a chassis, a host platform and double movable arms, wherein the host platform is arranged on the chassis and is connected with the double movable arms through hinges; the double movable arms are rigidly connected through two connecting bridges; two movable arm hydraulic oil cylinders which synchronously act are arranged between the host platform and the double movable arms; the two ends of the movable arm oil cylinders are hinged with the host platform and the double movable arms respectively; the end parts of the double movable arms are hinged with a mounting platform; a leveling hydraulic oil cylinder is arranged between the mounting platform and the connecting bridges of the double movable arms; and the mounting platform is provided with a lifting platform, a truck mounted crane and a multidirectional adjusting manipulator. The multi-functional tunnel operation trolley has the technical effects that mounting work of an arching can be finished by only two or three operation staffs, mechanical operation of mounting of the arching can be realized, an I steel arching and a grid arching can be clamped and then lifted to any position in a tunnel, quick mounting is realized, the construction time is saved, the working efficiency is increased and other construction operations are facilitated.

Description

technical field [0001] The invention relates to tunnel construction equipment. Background technique [0002] Steel arches (grid arches), The surrounding rock is reinforced by means of bolting, hanging steel mesh, shotcrete and other means to ensure construction safety. Taking the installation of tunnel arches as an example, at present most of the installations of arches in China mainly rely on manual work. First of all, the arch frame is placed under the rock formation, fixed with anchor rods, and the multi-section arch frame is sequentially connected into a ring with bolts. During the construction process, the weight of a single arch section is as high as 200-400 kg, and more than ten workers are required to work at the same time. Affect the progress of tunnel construction. Contents of the invention [0003] The object of the present invention is to provide a tunnel operation trolley for multi-functional requirements such as arch installation, bolt installation, net h...
