Abstract
The invention provides a kind of cutterhead driving device for construction of tunnel machinery, comprise permagnetic synchronous motor, reductor and planetary gear that order is connected.By the number of poles of permagnetic synchronous motor is set to a lot, just can significantly reduces its output speed, thus significantly reduce the input speed of reductor, reduce the speed reducing ratio of reductor, the step of reduction of reductor is reduced.
Description
Technical field
The present invention relates to a kind of cutterhead driving device of construction of tunnel machinery, particularly relate to a kind of cutterhead driving device for complete-section tunnel boring machine.
Background technology
Construction of tunnel machinery for tunneling boring set of tunneling construction comprises balancing earth-pressure shielding machine, slurry balance shield machine, hard rock mole, etc.In these engineering machinery, utilize cutterhead to cut the soil body.Therefore, the drive unit of cutterhead is the critical component in complete-section tunnel boring machine.Cutterhead driving device stable, reliable, efficient, determines the efficiency of complete-section tunnel boring machine construction.
The cutterhead driving device of existing complete-section tunnel boring machine mainly contains two kinds of forms.The first comprises hydraulic motor, reductor and planetary drives structure, and the second comprises variable-frequency motor, reductor and planetary drives structure.But these two kinds of combination driving devices have a common shortcoming, no matter be namely adopt hydraulic motor or variable-frequency motor, its output speed is all higher, and cutterhead rotating speed in practical application is lower.This just requires that the speed reducing ratio of reductor is comparatively large, and reductor at least adopts two reduction gear, and needs extra water cooling plant for its heat radiation.What this finally caused these two kinds of drives structure takies that volume is large, noise is high, it is bad to dispel the heat.Meanwhile, the transmission efficiency of these two kinds of drives structure is low, financial cost is high.
Summary of the invention
The object of this invention is to provide a kind of cutterhead driving device for construction of tunnel machinery, it is energy-efficient, and structure is simple, and cost is low.
According to the present invention, provide a kind of cutterhead driving device for construction of tunnel machinery, comprise permagnetic synchronous motor, reductor and planetary gear that order is connected.
In one embodiment, be provided with at least two axial mechanisms be made up of a permagnetic synchronous motor and a reductor, wherein each axial mechanism jointly acts on a planetary gear.
Needs as the case may be, reductor is three grades of reductors, double reduction machine or first class reducer.
In one embodiment, cutterhead driving device also comprises water cooling plant or the air cooling equipment for providing cooling for reductor.Certainly, also can not cooling unit be set, and dispels the heat by naturally cooling.
In a specific embodiment, permagnetic synchronous motor is 20 poles, and the speed reducing ratio of described reductor is i=30.
Comprising in permagnetic synchronous motor, reductor and planetary cutterhead driving device according to of the present invention, by the number of poles of permagnetic synchronous motor is set to a lot, just can significantly reduce its output speed, thus significantly reduce the input speed of reductor, reduce the speed reducing ratio of reductor.Like this, the step of reduction of reductor reduces, and the progression scope that can realize reducing gear is by 1 grade to 3 grades.Also bring joint space-efficient advantage thus.
In addition, reductor can adopt the nature type of cooling under normal circumstances, only need adopt water-cooled or air cooling way when overheated.
Compared with prior art, the cutterhead driving device for construction of tunnel machinery provided by the present invention has following effect:
1) permanent magnet synchronous electric engine efficiency is high, and power factor is high, thus reduces energy consumption and running cost.
2) permagnetic synchronous motor number of poles is many, and rotating speed is low.Therefore, the gearratio of reductor is little, and transmission efficiency is high, and noise is little, and volume is little, is more applicable to the requirement that the shield body space of complete-section tunnel boring machine is narrow and small.
3) brand-new component combination mode makes whole driving device structure simple, and easy to maintenance, cost is low.
Accompanying drawing explanation
Fig. 1 shows according to cutterhead driving device of the present invention.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with a specific embodiment, the present invention is elaborated.
As shown in Figure 1, especially can be used for complete-section tunnel boring machine according to the cutterhead driving device 10 of this specific embodiment of the present invention.This cutterhead driving device 10 comprises the permagnetic synchronous motor 1, reductor 2 and the planetary gear 3 that are connected successively.Wherein, the output shaft of permagnetic synchronous motor 1 is connected with the input of reductor 2, and the output of reductor 2 is connected with planetary gear 3.
In the present embodiment, be provided with two groups of permagnetic synchronous motors 1 and reductor 2, thus constitute two groups of axial mechanisms, they drive planetary gear 3 jointly, thus drive the cutterhead of tunnel machine.But be appreciated that those skilled in the art can arrange more groups of permagnetic synchronous motors 1 and reductor 2 according to the needs of actual conditions.
By the speed reducing ratio of the number of poles and reductor 2 of suitably selecting permagnetic synchronous motor 1, desired cutterhead rotating speed can be realized and export.In a concrete example, permagnetic synchronous motor 1 is 20 poles, and its specified output speed is 300rpm.Meanwhile, adopt the reductor 2 of speed reducing ratio i=30, its specified output speed is 10rpm.In this case, the rotating speed of cutterhead is 10rpm.Owing to have employed the permagnetic synchronous motor 1 of the large torque of the slow-speed of revolution, speed reducing ratio and the input speed of reductor 2 all reduce.Therefore, reductor 2 can adopt primary speed-down mechanism, and reductor is the nature type of cooling.This just enormously simplify the structure of existing complete-section tunnel boring machine cutterhead driving device, saves space and cost.
Above by the simplest cutterhead driving device of one to invention has been detailed description, and describe beneficial effect of the present invention with most typical data, this enables those skilled in the art to realize or use the present invention.To be apparent to one skilled in the art to the multiple amendment of these embodiments.General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
