Abstract

The invention provides a hoisting mechanism of a double-lifting-appliance crane and the crane. The hoisting mechanism comprises a speed reducer and two transmission systems connected to the two sides of the speed reducer, each transmission system comprises a low-speed shaft close to the speed reducer and a high-speed shaft away from the center of the speed reducer, the high-speed shafts are connected with a driving system, each driving system comprises a motor and a transmission shaft, and the transmission shafts are connected with the high-speed shafts of the speed reducers through couplings. A low-speed shaft of the speed reducer is connected with a winding drum; and the winding drum realizes lifting of a lifting appliance connected with the winding drum by winding a steel wire rope. The hoisting mechanism is formed by connecting the low-speed shafts of the double transmission systems, the other set of transmission system can be used for driving the whole mechanism to work in an accident state such as a single motor fault or shaft breakage and tooth breaking of a high-speed shaft system or a middle shaft system of a speed reducer on one side, and the production efficiency is not influenced. Low-speed shaft connection is realized through an idle wheel arranged in the speed reducer, so that two sets of safety brakes and speed detection equipment which are high in price can be saved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a hoisting mechanism of a crane with double spreaders and the crane. Background technique [0002] The tundish is the process equipment for steelmaking and continuous casting in steel plants. Its function is to pour molten steel refined in the converter into it through the ladle, and then distribute it to each crystallizer through the water distribution port on the tundish to complete the distribution of molten steel. The crane for lifting the tundish is used to lift the tundish from the rotary table to a safe position in order to avoid the expansion of the accident when the continuous casting machine fails. The tundish is generally equipped with four hanging trunnions. Due to the fact that some tundish nozzles are set to one side, and the location of the pouring point of the ladle is not the center point, etc., most of the tundishes currently used by domestic steel mills are The...
