Abstract
The utility model provides a mechanism of fighting is left to excavator, relates to the mining excavator of mechanical type. The problem of prior art inefficiency, the technique that the energy consume is big, the maintenance is difficult, the reliability is low is solved. The utility model discloses a: the motor, the frame, the reel, the reel pivot, left bearing, right bearing, the shaft coupling, the motor is permanent magnet synchronous motor, fixes on the frame, the output of motor pass through the shaft coupling with reel pivot lug connection. The utility model discloses a power supply of adoption converter realizes permanent magnet synchronous motor's low -speed operation, exports great torque, direct drive load work, and the cancellation speed reducer, the structure is simpler, practical, has improved the work efficiency of system.
Description
Technical field
The utility model relates to a kind of Kai Dou mechanism of excavator, particularly a kind of mechanical mining excavator Kai Dou mechanism.
Background technology
The Kai Dou mechanism of mechanical mining excavator is as a typical machinery, and electrically the equipment of one, is responsible at the bottom of the bucket opening scraper bowl, and coordinating digging mechanism to complete the vital task of unloading materials, is the essential core building block of mechanical mining excavator.
Current mechanical mining excavator open bucket mechanism motor and dragging system, all also exist that some we do not wish the shortcoming that exists and problem.The existence of such as reductor, causes the transmission efficiency of whole transmission system greatly to reduce, and there are large problems difficult in maintenance.Because reductor input connects the threephase asynchronous of a high-speed cruising, during operation, its bearing noise is large, and gear drive inevitably also exists mechanical wear, along with the increase of running time, wearing and tearing make gap between moving component become large, cause noise aggravation, transmission efficiency decline.In mechanical driving device, speed reducer drive system effectiveness is low, and energy dissipation is large, and running the shortcomings such as noise is large cannot overcome.Meanwhile, the oil gas produced in the wearing and tearing of reductor and transmission slip process and greasy dirt also can to environments.
Utility model content
The purpose of this utility model is intended to the shortcoming overcoming prior art, provides a kind of mechanical mining excavator Kai Dou mechanism, solves existing machinery formula mine excavator and opens the technical problems such as bucket mechanism efficiency is low, energy dissipation is large, difficult in maintenance, reliability is low.
The utility model is achieved through the following technical solutions:
A kind of bucket opening mechanism of excavator, comprising: motor, support, reel, reel rotating shaft, left bearing, right bearing, shaft coupling, described reel is installed in described reel rotating shaft, and described reel rotating shaft is fixed on described support by left bearing and right bearing, it is characterized in that, described motor is permasyn morot, is fixed on support, and the output of described motor is directly connected with described reel rotating shaft by shaft coupling.
Further, described bucket opening mechanism of excavator, also comprises frequency converter and cable, and described frequency converter is connected with described motor, to described motor by described cable.
Compared with prior art, usefulness of the present utility model is:
1, the output of permasyn morot is directly installed in the reel rotating shaft of mechanical mining excavator Kai Dou mechanism, eliminate reductor, simple and practical, improve system works efficiency, enhance the reliability of system cloud gray model, reduce maintenance difficulties and cost;
2, frequency converter is directly connected with permasyn morot, realizes permasyn morot variable frequency starting and operation, and dynamic properties of mechanism is good, and detent torque is large, and meanwhile, system can seamlessly transit operation and stepless speed regulation at four-quadrant, and energy-saving effect is remarkable;
3, adopt permasyn morot, greatly reduce the weight of motor and the complexity of internal construction, for production and installation bring a lot of facility;
4, adopt permasyn motor direct to meet driving device formula mine excavator Kai Dou mechanism, motor-driven mode can be single driving.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
The exemplary embodiments embodying the utility model feature & benefits will describe in detail by reference to the accompanying drawings in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from protection domain of the present utility model, and explanation wherein and to be shown in be use when explain in essence, and be not used to limit the utility model.
As shown in Figure 1, a kind of bucket opening mechanism of excavator, comprise: motor 1, support 9, reel 5, reel rotating shaft 4, left bearing 8, right bearing 10, shaft coupling 3, frequency converter 6 and cable 7, described reel 5 is installed in described reel rotating shaft 4, described reel rotating shaft 4 is fixed on described support 9 by left bearing 8 and right bearing 10, described motor 1 is permasyn morot, be fixed on support 9, the output 2 of described motor is directly connected with described reel rotating shaft 4 by shaft coupling 3, described frequency converter 6 is connected with described motor 1 by described cable 7, power to described motor 1.
Although exemplary embodiment describe the utility model with reference to several, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Specifically can implement in a variety of forms due to the utility model and not depart from spirit of the present utility model or essence, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and should explain widely in the spirit and scope that claims limit, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claims and contained.
