The invention discloses a modular integrated hoisting mechanism of a crawler crane, which comprises a rack, a hoist, a clamp plate brake, a three-coil protector and a pawl, wherein the three-coil protector and the pawl are connected on the rack through pin shafts, the clamp plate bake is fixed on a base of the rack through bolts, the hoist is connected with a flange of a planetary reducer through bolts, the fixed end of the planetary reducer is fixed with the rack through bolts, and the hoisting mechanism is integrally connected with a turnplate through pin shafts. According to the invention, the modular design concept is adopted, the hoist, the brake, the three-coil protector and the pawl are modularly integrated on the hoisting mechanism, and the hoisting mechanism is integrally connected with the turnplate through the pin shafts. In assembly and maintenance, the quick assembly and disassembly can be realized, the maintenance space is large, the processing errors can be greatly reduced, the maintenance is simple, the assembly and disassembly are convenient, the assembly and disassembly time can be greatly shortened, the maintenance cost is reduced, and the production efficiency can be improved.
Description
1. Technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a modular integrated winch mechanism of a crawler crane. 2. Background technology [0002] At present, the hoisting mechanism of crawler cranes in China mostly adopts a structure in which pawls and brakes are respectively fixed on the turntable, which has large assembly size errors, inconvenient structural maintenance, and a large amount of turntable processing. The pawl, three-ring protector, brake and rope stop are modularized and integrated to reduce the assembly size error, which can greatly reduce the assembly time, reduce the processing amount of the turntable, and make maintenance more convenient and improve work efficiency. 3. Contents of the invention [0003] The object of the present invention is to provide a modularized integrated hoisting mechanism of a crawler crane, which can make the hoisting hoisting mechanism of the crawler crane mo...
