A kind of electroplating traveling crane travel mechanism
Technical field
The utility model relates to a kind of electroplating traveling crane, particularly relates to a kind of electroplating traveling crane travel mechanism.
Background technology
It is well known that driving mechanism is mainly used in being placed in different plating tanks extension tool according to manufacturing technique requirent, and taking out in the predetermined time and be transported in the plating tank of next station, the quality of its design directly determines electroplating efficiency and the electroplating quality of plating line. Travel mechanism is the important component part of electroplating traveling crane, and for driving, electroplating traveling crane advances or retreats for it.
At present, generally there is following shortcoming in the travel mechanism of traditional electroplating traveling crane:
1) because of Structure Designing Problem, cause the force-bearing situation bearing the bigger component of load unreasonable, affect its work-ing life;
2), in walking, it is that simple being rolled by roller controls walking precision so that the walking precision of driving is poor;
3) drive-motor is fixed by welding on deep beam, needs the framework changing whole travel mechanism after parts damages, installs with maintenance cost higher.
Practical novel content
The purpose of this utility model is to provide a kind of electroplating traveling crane travel mechanism, its feature having long service life, walking precision height and being convenient to installation and safeguard, to solve the problems referred to above that in prior art, electroplating traveling crane travel mechanism exists.
For reaching this object, the utility model by the following technical solutions:
A kind of electroplating traveling crane travel mechanism, it comprises traveling vehicle frame, it is provided with deep beam between described traveling vehicle frame, wherein, and the bottom of described traveling vehicle frame is provided with four rolling, described four rolling has two for driving roller, two other is driven roller, described driving roller is installed on and drives on wheel shaft, described driving wheel shaft is connected with drive shaft by shaft coupling, the drive-motor that described drive shaft is connected on described deep beam, and described driving wheel shaft is provided with gear in the outside of described driving roller, coordinate described gear, on described traveling vehicle frame, tooth bar is installed, described driven roller is installed on described follower shaft, described follower shaft is connected with transmission shaft by shaft coupling.
Especially, the both sides correspondence of described traveling vehicle frame is provided with walking case, described driving roller, drives wheel shaft, gear, driven roller and follower shaft to be all arranged in walking case, and described driving wheel shaft and follower shaft are arranged on described walking case by bearing.
Especially, described drive-motor is arranged on motor fixing plate, and described motor fixing plate is bolted on described deep beam.
Especially, the two ends of described driving vehicle frame are all provided with anti-collision block.
Especially, the two ends of described drive shaft and transmission shaft are all installed on described driving vehicle frame by rolling bearing units.
The beneficial effects of the utility model are, compared with prior art described electroplating traveling crane travel mechanism has the following advantages:
1) walking manner adopts rack and pinion drive mechanism and roller rolling dual-driving-mode to promote, and promotes driving motion while the weight of the whole driving of roller supporting, and rack and pinion drive mechanism does not almost bear driving weight, only provides the thrust of driving motion. This kind of mode improves the force-bearing situation of roller and rack-and-pinion, and what extend that these bear the bigger component of load benefits from the life-span;
2) rack and pinion drive mechanism can realize the location of driving accurately by controlling the rotation of electric motor so that the walking of driving is more accurate, overcomes the defect that in simple roller rolling control, roller walking precision is not high;
3) step-down gear retaining plate is fixed with bolts on walking deep beam, instead of it is welded on walking deep beam, make can change easily during these damage of components, and the framework of whole travel mechanism need not be changed, add the interchangeability of driving component, save installation and maintenance cost.
