Abstract
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
One, technical field
The invention belongs to mechanical equipment technical field, be specifically related to a kind of crawler crane modularization integral hoist structure.
Two, background technology
At present domestic crawler crane promotes hoisting mechanism and adopts ratchet, drg to be separately fixed at structure on the turntable more, and its fitted position error is large, and structural repair is inconvenient, and the turntable processing capacity is large.And ratchet, three circle protectors, drg and gear rope device are adopted the modularization Integrated design, and reduce the fitted position error, can greatly reduce time of setting up, reduced the processing capacity of turntable, also make maintenance convenient, increase work efficiency.
Three, summary of the invention
The purpose of this invention is to provide a kind of crawler crane modularization integral hoist structure, can make crawler crane promote hoisting mechanism by it more efficient, simple when assembling and keep in repair.
The technical solution used in the present invention is: crawler crane modularization integral hoist structure comprises frame, winch, clipper disk brake, three circle protector and ratchets; three circle protectors and ratchet are connected on the frame by bearing pin; clipper disk brake is bolted on the gantry base; the winch flange connect of bolt and planetary reducer; the fixed end of planetary reducer is fixed by bolt and frame, and hoisting mechanism is whole to adopt bearing pin to connect with turntable.
The present invention adopts modular design concept, and winch, drg, three circle protectors, ratchet modularization are integrated on the hoisting mechanism, and hoisting mechanism is whole to adopt bearing pin to be connected with turntable.Can realize Fast Installation and dismounting when assembling and maintenance, service clearance is large, has greatly reduced Mismachining tolerance, safeguards that simply easy installation and removal can significantly reduce the installing/dismounting time, has reduced maintenance cost, has improved production efficiency.
