Abstract
The present invention relates to a three-in-one rotary mechanism for a metallurgical crane, which comprises an upper beam, a lower beam, a parallel shaft type gear motor, a slider coupling and a central shaft. The present invention is characterized in that the parallel shaft type gear motor is connected to the upper beam, an output hollow shaft of the gear motor is connected with the central shaft through the slider coupling and the central shaft is connected with the lower beam. The present invention is arranged on a metallurgical crane, which enables the self weight of the metallurgy crane to be greatly lightened, factory building height above a crane track surface to be decreased, difficulty and production cost of equipment fabrication to be lowered and workpiece rotary actions to become light and flexible.
Description
Technical field
The present invention relates to the swing type mechanism that a kind of crane for steelworks use is used, particularly a kind of three-in-one swing type mechanism.
Background technology
On some cranes for steelworks use (for example magnet crane and ladle carne), the crossbeam (for example lifting beam with electromagnets and gantry hook crossbeam that hangs the molten steel jar) of directly installing load-engaging device often needs to have the horizontal rotation function.For obtaining this function, traditional structure has two kinds, a kind of employing double-layer trolley, and upper trolley is turned round along the circular orbit on the lower floor's dolly that is laid in, thus drive lifting beam with electromagnets or gantry hook crossbeam turn round; A kind of be with entablatrance that lifting mechanism connects mutually on, it is that magnetic chuck foundation or gantry hook crossbeam turn round that the swing type mechanism of installing huge heaviness drives cross sill.The shortcoming of these two kinds of structural schemes is: 1. hoisting crane cause the hoisting crane wheel load to increase, thereby the factory building height dimensional characteristic more than the crane track plane is big from great; 2. the swing type mechanism complexity causes that the device fabrication difficulty is big; 3. use at the middle and upper levels dolly have from the danger of ring rail derailing (sliding down).
Summary of the invention
Purpose of the present invention just provides a kind of swing type mechanism of compact conformation.
The present invention is achieved like this, it comprises entablatrance, cross sill, parallel-axis type gear motor (being three-in-one retarder), sliding cross coupling, axis, on entablatrance, connect the parallel-axis type gear motor, the output hollow shaft of motor is connected with axis by sliding cross coupling, axis connects cross sill, cross sill can be the magnetic-disc crossbeam, also can be gantry hook crossbeam.
The present invention is installed on the crane for steelworks use, can alleviate the hoisting crane deadweight greatly, reduces the above factory building height of crane track face, has reduced device fabrication difficulty and productive costs, makes workpiece revolution action become flexibly light and handy.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1. pulleys, 2. parallel-axis type gear motor, 3. entablatrance, 4. sliding cross coupling, 5. axis, 6. cross sill in the drawings.
The specific embodiment
As shown in Figure 1, the present invention connects a parallel-axis type gear motor 2 on entablatrance 3, the output hollow shaft of motor is connected with axis 5 by sliding cross coupling 4, axis connects cross sill 6, during use, motor driven axis rotation on the entablatrance, axis drives cross sill 6 rotations, cross sill can be a lifting beam with electromagnets, it also can be gantry hook crossbeam, in order to reduce the height of equipment, can replace the parallel-axis type gear motor with worm and gear gear motor or bevel gear motor, entire mechanism is suspended on by pulley 1 on the steel rope of lifting mechanism and realizes integral elevating.
