Description
Technical field
The utility model belongs to elevator machinery technical field, is specifically related to a kind of travel driving unit, particularly a kind of crawler crane travel driving unit.
Background technology
Crawler crane is contained on crawler body by hoisting operation part, walking relies on the runabout crane of crawler attachment, working environment is relatively severe, a complete set of various gear and reductor are articulated and connected and drive, and deceleration rank is more, and transmission link is complicated, part comparison is heavy, structure is comparatively complicated, and dismantle after et out of order, keep in repair and change more loaded down with trivial details, therefore a kind of compact conformation, drive configuration easy to detect just have Practical significance very much.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of compact conformation, crawler crane travel driving unit easy to detect.
The purpose of this utility model is achieved in that a kind of crawler crane travel driving unit, it comprises drive wheel, described drive wheel lower end is hinged with crawler belt, live axle is interspersed with in described drive wheel, described live axle left end is provided with vehicle wheel frame, described live axle right-hand member is provided with reducing gear, described reducing gear is hinged with wheel reduction gear, retarder bearing is provided with on the left of described wheel reduction gear, on the right side of described wheel reduction gear, coupler is provided with drive motor, described drive motor is outside equipped with protective cover, exhaust fan is provided with on the upside of described protective cover, louvre is provided with on the downside of described protective cover.
Described wheel reduction gear is built-in wheel reduction gear.
Described drive motor is variable-frequency motor.
Described protective cover is square.
The beneficial effects of the utility model: the utility model adopts built-in wheel reduction gear to be articulated and connected reducing gear, reducing gear connects live axle drive drive wheel simultaneously, which reduce middle complicated transmission device, make drive configuration more compact, and decrease trouble point, make maintenance, dismantle and change more convenient, drive motor adopts variable-frequency motor, can regulate and control more precisely with energy-conservation like this, protective cover can protect variable-frequency motor not by the impact of external environment, protection variable-frequency motor reduces the probability damaged, the exhaust fan of upside coordinates the louvre of downside can stroke convection current in protective cover, reduce the temperature in protective cover, total the utility model has compact conformation, easy to detect, reduce fault, practical advantage.
