Deflection clamping device used for installation of arch frame in tunnel construction

Abstract

The invention discloses a deflection clamping device used for installation of an arch frame in tunnel construction. The deflection clamping device contains a vertical revolving support device, a hydraulic winch, a limiting pulley, a deflection arm and a lifting support cantilever. The side edge at one end of the deflection arm is fixedly connected to the vertical revolving support device through bolts. The other end of the deflection arm is provided with a cantilever end. One end of the lifting support cantilever is fixedly connected to a fixing end of the deflection arm. The vertical revolving support device is fixedly connected to a base of a construction platform. Rapidly and flexible butt-joint and firm connection of an installation flange of the arc frame in tunnel construction are realized. The same kind of equipment does not need to perform accurate operation repetitively so that a time-consuming and labor-consuming problem of hard butt-joint is resolved. Meanwhile, the device can work with a main clamping device (a middle arm clamping device) to form a three-point fixing type after installation and formation of the overall arch frame so that the front-and-back distance of the overall arch frame is adjusted. It is no longer difficult to adjust the overall arch steel frame by other similar equipment. The device obtains good effect.

Description

Technical field [0001] The invention relates to a clamping device, in particular to a deflection clamping device used for tunnel construction arch frame installation, and belongs to the technical field of construction machinery. Background technique [0002] At present, some construction equipment for the installation of steel arches in tunnel construction has appeared on the market, and its function is mainly reflected in the installation and construction of steel arches. In the arch installation construction, the automatic picking and clamping of the steel arch is a difficult problem to solve, and it has not been solved at present. Some manufacturers’ products can be automatically picked under very ideal conditions, but they also need It can be completed only with the assistance of workers, but other things basically require manual picking. On the one hand, more manpower is required, and secondly, there is a greater safety risk. Summary of the invention [0003] The technical p...

Problems solved by technology

At the same time, after the entire arch frame is installed and formed, it can cooperate with the main clamping device (middle arm clamping device) to form a three-point fixed type to adjust the front and rear distances of the entire arch frame, so as to solve the problem of some existing similar equipment on the entire steel frame after forming. Rack adjustment is more difficult problem
