Abstract
The utility model discloses a modular integrated hoisting mechanism of a crawler crane, which comprises a stand, a hoister, a caliper disc brake, a three-circle protector and a pawl, wherein the three-circle protector and the pawl are connected on the stand by pin shafts; the caliper disc brake is fixed on a base of the stand by a bolt; the hoister is connected with a planetary reducer by a flange through a bolt; a fixed end of the planetary reducer is fixed with the stand by a bolt; and the whole hoister is connected with a rotary table by a pin shaft. The modular integrated hoisting mechanism of the crawler crane adopts a modular design concept, so that the hoister, the brake, the three-circle protector and the pawl are integrated on the hoisting mechanism in a modular way, and the whole hoister is connected with the rotary table by the pin shaft. During installation and maintenance, rapid installation and disassembly can be realized; and the modular integrated hoisting mechanism is large in maintenance space, greatly reduces the machining error, is simple to maintain and convenient to assemble and disassemble, thus greatly reducing the time used for assembly and disassembly, reducing the maintenance cost and improving the production efficiency.
Description
One, technical field
The utility model belongs to mechanical equipment technical field, is 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 utility model provides a kind of crawler crane modularization integral hoist structure, and it is more efficient, simple when assembling and keep in repair to make crawler crane promote hoisting mechanism by it.
The technical solution adopted in the utility model 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 utility model 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.
