Clamping device and tunnel arch operating vehicle

Abstract

The invention discloses a clamping device which comprises a support. A supporting plate is movably connected to the support. The portion above the supporting plate is used for installation of a working platform. A cantilever crane is movably connected to the supporting plate. A gripper is movably connected to the cantilever crane. A pitch oil cylinder is arranged between the supporting plate and the cantilever crane and used for controlling pitching of the cantilever crane. A clamping oil cylinder is arranged on the gripper and used for controlling the gripper to conduct clamping or releasing. The invention further provides a tunnel arch operating vehicle provided with the clamping device of any item. The clamping device and the tunnel arch operating vehicle have the advantages that by means of the structural design of the clamping device and the tunnel arch operating vehicle, clamping of structures such as steel arches can be conveniently, easily and safety achieved in the tunnel construction process, the requirement for the number of operators can be lowered, the labor intensity is lowered, the production efficiency is improved, and the construction safety is ensured.

Description

technical field [0001] The invention relates to the field of construction machinery, and more specifically, to a clamping device and a tunnel arch operation vehicle. Background technique [0002] The tunnel arch work vehicle is generally controlled by a hydraulic or electric system with multiple hydraulic cylinders. A work platform is set on the hydraulic cylinder, and the hydraulic cylinder drives the work platform to lift up and down. The operator stands on the work platform to perform high-altitude operations. The tunnel arch operation vehicle is a relatively advanced construction machinery and equipment in contemporary times. With the help of the tunnel arch operation vehicle, the operator can be lifted to a certain height, so as to conveniently realize the tunnel arch construction and other high-altitude production operations. With the development of modern science and technology, the research and development of tunnel arch operation vehicles has been greatly developed....

AI Technical Summary

Problems solved by technology

In order to facilitate the erection of steel arches, etc., operators usually need to find ways to clamp and fix the installation of steel arches and other mechanisms when they are on the work platform. Due to the lack of special clamping devices on conventional tunnel arch operation vehicles, steel The installation of arches and other mechanisms can only be done manually, and the arches are installed in place by manpower with the help of a simple bench. This method requires a lot of construction workers, high labor intensity, and low work efficiency; at the same time, the steel arches in the construction process The frame is easy to collapse, and the construction risk is very high. It has become less and less suitable for the rapid construction of the tunnel.
