Upper crane part of formwork grabbing and hoisting alignment machine

Abstract

The invention discloses an upper crane part of a formwork grabbing and hoisting alignment machine. The upper crane part comprises a base, a big arm hinged to the base, a telescopic boom slidably connected with the big arm, a small arm and a rotating arm. The telescopic boom, the small arm and the rotating arm are sequentially connected end to end. The small arm and the rotating arm are connected through a rotating arm slewing bearing. The plane where the rotating arm slewing bearing is located is kept perpendicular to the plane formed by the small arm and the telescopic boom all the time. Graspers are arranged at the tail end of the rotating arm, and the rotating arm is connected with each grasper through a grasper slewing bearing. The included angle between the slewing center of each grasper and the rotating arm is zero. According to the upper crane part of the formwork grabbing and hoisting alignment machine, the machine has multiple purposes, the labor cost is lowered, work efficiency is improved, and work quality is improved.

Description

technical field [0001] The invention relates to engineering machinery, in particular to the boarding part of a formwork snatch alignment machine. Background technique [0002] For underground or tunnel projects with small cross-sections and constantly changing cross-sections, ordinary lifting equipment or tunnel trolleys are not suitable due to the limitations of factors such as fuselage volume, range of motion, and lifting flexibility, while the freedom of self-propelled aerial work vehicles The degree is limited, and the alignment adjustment of the template cannot be completed. Therefore, for this type of project, a large number of formwork handling, formwork or demoulding operations must rely on manual labor. There are following problems in this way: 1) the labor intensity is high, and it is very easy to cause personal injury. 2) Very inefficient. 3) Templates are easily damaged. Contents of the invention [0003] In order to solve the problems existing in the prior...
