Main clamping device for installation of tunnel construction arch support

Abstract

The invention discloses a main clamping device for installation of a tunnel construction arch support. The main clamping device comprises a rotating base, a clamping head base, a rubber supporting back plate, a steel arch support clamping plate, a clamping connecting rod and a longitudinal rotary support device, wherein the rotating base is fixedly connected with the longitudinal rotary support device through bolts, the rotating base is fixedly connected with the clamping head base through a square tube, the rubber supporting back plate is arranged on one side of the clamping head base, the clamping connecting rod is hinged to the other side of the clamping head base, the steel arch support clamping plate is hinged to the movable end of the clamping connecting rod, and the longitudinal rotary support device is fixedly connected to the pedestal of a construction platform. The main clamping device for installation of the steel arch support can rotate by 180 degrees, the first section (middle section) of the steel arch support can be automatically picked up under any working condition and can also be safely clamped in a balanced mode, the process can be completed with little assistance from only one worker in construction, and the problem is solved that some devices of the same type need complex and precise rigid butt joint which consumes time and labor.

Description

technical field [0001] The invention relates to a clamping device, in particular to a main clamping device used for installing tunnel construction arches, 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 installation and construction of arches, the automatic picking and clamping of steel arches is a difficult problem, which has not been solved at present. Some manufacturers' products can be automatically picked up under very ideal conditions, but they also need It can only be completed with the assistance of workers, but other things basically need to be picked up manually. On the one hand, it requires a lot of manpower, and secondly, there is a greater safety risk. Contents of the invention [0003] The tec...
