Abstract
The invention discloses a driving device for a crane lifting mechanism. The driving device is characterized in that a high-speed end and a low-speed end of a speed reducer are of a hollow shaft structure; a driving end of a variable-frequency motor is fixedly arranged on one side of the high-speed end of the speed reducer through a connecting sleeve; and a driving shaft of the variable-frequency motor is sleeved with the hollow shaft structure of the high-speed end, and the motor/speed reduction/braking integrated driving device is formed. Compared with the prior art, the driving device is simple in structure, is high in transmission efficiency, and guarantees accurate calibration of a mechanical device. Component dislocation caused by structure deformation is solved, a coiling barrel of the lifting mechanism can be designed in a two-point supporting structural form conveniently, the structure winding degree of the coiling barrel does not cause connection dislocation of the driving end and a gearbox, high-frequency stress repetition during connection of the coiling barrel and the gearbox is avoided, and the service life of a gearbox bearing is prolonged. The driving device can be widely applied to various lifting mechanisms, reduces the self-weight and outline size, and improves work efficiency.
Description
Technical field
The present invention relates to crane technical field, the driving means of a kind of crane hoisting mechanism.
Background technology
Crane is harbour handling workpiece use, is the important production equipment of shipyard, and its principal organ is lifting mechanism and jib lubbing mechanism.Present lifting mechanism speed end is generally connected with high-speed shaft of speed reducer with shaft coupling by compensating axle by motor, and mounting seat formula brake, and low speed end is coupled together decelerator and reel by drum coupling.
Prior art there is the problem that lifting mechanism speed end is generally connected with high-speed shaft of speed reducer with shaft coupling by compensating axle by motor, and mounting seat formula brake, low speed end is coupled together decelerator and reel by drum coupling, this structure is all to be connected with vehicle frame by base, structure comparison is heavy, through being commonly formed redundant structure, force analysis is indefinite, drum coupling often damages, the normal work of impact, make maintaining cost increase, the structure of this heaviness make lifting trolley deadweight substantially little car weight more other than external ad eundem a lot of simultaneously.
Summary of the invention
It is an object of the invention to the driving means of a kind of crane hoisting mechanism designed for the deficiencies in the prior art, use decelerator and the group of motors integralization driving means of hollow shaft structure, compact conformation, guarantee the accurate calibration of machinery, avoid the parts dislocation caused because of malformation greatly, there is no the revolving part exposed, thus add safety, maintenance needs greatly reduces, hollow axle decelerator can make spool designs become two point-supported versions, reel because bear load and when bending hinged, the structure winding degree of reel is not result in the connecting staggered of drive end and gear-box, when reel stress rotates, reel/gear-box connects the stress repetition not havinging high frequency, therefore reel drive end does not has fatigue damage point, substantially prolongs the service life of box bearing.
The object of the present invention is achieved like this: the driving means of a kind of crane hoisting mechanism, including decelerator and the adjustable frequency motor being provided with Electromgnetic seat brake, it is characterized in that speed end and the low speed end of decelerator use hollow shaft structure, the drive end of adjustable frequency motor is fixedly installed on the speed end side of decelerator by branch sleeve, the drive shaft of adjustable frequency motor is inserted into speed end at branch sleeve and is bonded with hollow shaft structure, composition integrates the driving means of motor/deceleration/braking, described branch sleeve two ends are that flange arrangement is fixing with adjustable frequency motor and decelerator to be connected.
The present invention compared with prior art has simple in construction, transmission efficiency is high, preferably improve the drive pattern of existing lifting mechanism, by motor, decelerator and brake are integrated, compact conformation, guarantee the accurate calibration of machinery, not only solve the parts dislocation caused because of malformation, and facilitate the spool designs of lifting mechanism to become two point-supported versions, make decelerator hinged when reel bends because bearing load, the structure winding degree of reel is not result in the connecting staggered of drive end and gear-box, when reel stress rotates, reel/gear-box does not haves the stress repetition of high frequency in connecting, greatly reduce the fatigue damage point of reel drive end, extend the service life of box bearing, can be widely applied in various lifting mechanism, alleviate deadweight and reduce overall volume, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is that the present invention specifically applies schematic diagram.
Detailed description of the invention
Refering to accompanying drawing 1, the present invention is made up of decelerator 1 and the adjustable frequency motor 2 being provided with Electromgnetic seat brake 3, speed end 5 and the low speed end 6 of described decelerator 1 use hollow shaft structure, the drive end of adjustable frequency motor 2 is fixedly installed on speed end 5 side of decelerator 1 by branch sleeve 7, and the drive shaft 4 of adjustable frequency motor 2 is inserted into the speed end 5 of decelerator 1 at branch sleeve 7 and is bonded with hollow shaft structure.Described branch sleeve 7 two ends are that flange arrangement is arranged with concentric circular with the drive shaft 4 of adjustable frequency motor 2 and the speed end 5 of decelerator 1, and by bolt, adjustable frequency motor 2 and decelerator 1 are connected into the driving means that motor/deceleration/braking is integrated.Decelerator 1 speed end 5 is hollow axle, the output shaft 4 of adjustable frequency motor 2 is inserted directly into this hollow axle, and with flange connection reducer 1 and adjustable frequency motor 2, the attachment structure making adjustable frequency motor 2 and decelerator 1 is extremely compact, transmission efficiency is greatly improved, the drive shaft 4 of adjustable frequency motor 2 does not has the revolving part exposed in being arranged on branch sleeve 7, thus adds the safety of device.
Refering to accompanying drawing 2, the present invention can make the reel 9 of lifting mechanism realize two point-supported versions, reel 9 is bearing on two point-supported bearing blocks 8, the power intake of reel 9 is connected with the hollow shaft structure of low speed end 6, substantially improve the stressing conditions of reel 9, make decelerator 1 hinged when reel 9 bends because bearing load, the structure winding degree of reel 9 is not result in the connecting staggered of drive end and gear-box, when reel 9 stress rotates, reel/gear-box does not haves the stress repetition of high frequency in connecting, greatly reduce the fatigue damage point of reel 9 drive end, and reel 9 dismounts more convenient when manufacturing and keep in repair.
More than simply the present invention is further illustrated, and is not used to limit this patent, all implements for equivalence of the present invention, within being intended to be limited solely by the right of this patent.
