Abstract
The invention discloses a cover plate hoisting device. A suspender is assembled on a hoisting support in a vertical direction guiding manner; an oscillating bar which is arranged obliquely in the vertical direction is assembled between the top of the suspender and the hoisting support; the upper end of the oscillating bar is hinged to the top of the suspender around the horizontally extending axis; the lower end of the oscillating bar is hinged to the hoisting support around the horizontally extending axis through a connecting piece; the connecting piece is movably assembled on the hoisting support in a horizontal direction guiding manner; a driving device is assembled between the oscillating bar and the hoisting support. The suspender descends under self gravity and traction of gravity of a lifting appliance and a cover plate, so the driving device hoists the cover plate through a link mechanism formed by the connecting piece, the oscillating bar and the suspender on the hoisting support, and the lifting principle and the lifting action are simpler.
Description
Technical field
