Main clamping device for installation of tunnel construction arch support

Abstract

The invention discloses a main clamping device for tunnel construction arch installation, which comprises a rotating seat, a clamping head base, a rubber support backboard, a steel arch clamping plate, a clamping connecting rod and a longitudinal rotary support device, the swivel seat is fixedly connected with the longitudinal slewing support device by bolts, and the swivel seat is fixedly connected with the base of the clamping head with a square tube. One side of the base of the clamping head is a rubber support back plate, and the other side is hinged There is a clamping link, and the movable end of the clamping link is hinged with a steel arch clamping plate, and the longitudinal slewing support device is fixedly connected to the base of the construction platform. It is a main clamping device for steel arch installation that can be rotated 180°. It realizes that the first section (middle section) of the steel arch can be automatically picked up under any working conditions, and at the same time it can be safely and balancedly clamped. During construction, only It can be completed by a worker with a little assistance, which solves the hard docking problem of some similar equipment that requires complex and precise operations and is time-consuming and labor-intensive.

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...
