Lifting device for building construction site

Abstract

The invention discloses a lifting device for a building construction site. The lifting device comprises a lifting table, wherein two sliding blocks are welded to the two side end surfaces of the lifting table correspondingly; the sliding blocks are arranged in sliding chutes in the inner wall of a supporting frame; the sliding chutes are arranged in the vertical direction; a first driving shaft is arranged on each of the other two side surfaces of the lifting table; the two ends of each first driving shaft are fixedly welded on the end surfaces of protrusions on the lifting table; the first driving shafts are fixedly connected with one end of each of chain belts in a surrounding manner; the other ends of the chain belts are connected with driving mechanisms; the middle sections of the chain belts are supported by second driving shafts; the two ends of each second driving shaft are welded to fixing blocks at the upper end of a fixing table. The lifting device for the building construction site is high in structural stability and steady in lifting; compared with a conventional form that a rigid rope is matched with a pulley for transmission, the lifting device disclosed by the invention has the advantages that the chain belts are matched with the driving shafts to realize lifting in a more synchronous and steadier manner under the driving of a hydraulic cylinder.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a lifting device for a building construction site. Background technique [0002] Most of the current lifting devices are large-scale equipment, which occupy a large area. Not only will resources be wasted for lifting items with a small height, but also because the lifting device occupies a large area, it is very difficult to adjust the low-height transportation in a small open space. ; And for most of the lifts that adopt steel ropes to cooperate with pulleys in the past, the strength is too low, the synchronization stability is too poor, and the safety factor is too low. Contents of the invention [0003] The object of the present invention is to provide a lifting device for a building construction site to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provide...
