Abstract

The invention relates to a turnover device of large components, which is composed of at least two sets of side by side turnover mechanism. The turnover mechanism is composed of an L-shaped bearing revolving body with short arms and long arms; the long arms are provided with revolving hinge and the bearing revolving body is articulated with a fixed hinged bearing via the revolving hinge; the long arms are also articulated with a piston rod of a lift cylinder; the other end of the lift cylinder is articulated with a hydraulic hinged bearing and the lift cylinder is connected with a hydraulic control device via pipelines. Compared with the prior art the invention has the advantages of being easy in operation, safe and reliable, low in equipment cost and convenient maintenance, which can realize the turnover of large components without damage.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to a turning device for large components. Background technique [0002] Hydraulic metal structural steel gates and large crane beams and other components are rectangular as a whole. Due to the needs of the production process, they need to be turned over many times during the production process. However, there is no automatic and relatively safe turning device for turning over such workpieces. , the commonly used overturning method is to use a crane to lift one end of the structural part to be overturned from the top of the structural part with a cable, so that one end of the structural part touches the ground, and the other end slowly rises. While one end is slowly lifted, it moves toward the ground end, so that the lifting end of the structural member rotates around the ground end. When the lifting end is lifted from one place to the highest by the crane, it is then ...
