Problems solved by technology
In this overturning method, there is a process in which the vertical lifting force of the lifting point gradually approaches and moves away from the gravity line of the structural member (the process of lifting one end of the structural member to the highest and then lowering it), when the vertical lifting force of the lifting point is lifted from the structure When one side of the gravity line of the component gradually approaches the gravity line of the structural component, an impact will occur, which brings certain difficulties to the control of the crane and brings unsafe factors, and it is also easy to cause damage to the structural component

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 ...
