Abstract
The invention discloses a cutting disc driving device used for tunnel engineering machinery. The cutting disc driving device used for the tunnel engineering machinery comprises a permanent magnet synchronous motor, a speed reducer, and a planetary gear, wherein the permanent magnet synchronous motor, the speed reducer, and the planetary gear are connected in sequence. The number of poles of the permanent magnet synchronous motor is set to be large, so that output rotation speed of the permanent magnet synchronous motor is significantly reduced, input rotation speed of the speed reducer is effectively reduced, speed reducing ratio of the speed reducer is reduced, and speed reducing levels of the speed reducer is reduced.
Description
Technical field
The present invention relates to a kind of cutterhead driving device of construction of tunnel machinery, relate in particular to a kind of cutterhead driving device for complete-section tunnel boring machine.
Background technology
The construction of tunnel machinery that is used for full bore tunnel 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 determined the efficient 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 is to comprise hydraulic motor, reductor and planetary drives structure, and the second is to comprise variable-frequency motor, reductor and planetary drives structure.Yet these two kinds of combination driving devices have a common shortcoming, no matter be namely to adopt hydraulic motor or variable-frequency motor, its output speed is all higher, and the cutterhead rotating speed in practical application is lower.This just requires the speed reducing ratio of reductor larger, and reductor adopts two reduction gear at least, and need to extra water cooling plant be its heat radiation.This finally cause these two kinds of drives structure take that volume is large, noise is high, heat radiation is bad.Simultaneously, the transmission efficiency of these two kinds of drives structure is low, financial cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of cutterhead driving device for construction of tunnel machinery, it is energy-efficient, and is simple in structure, and cost is low.
According to the present invention, a kind of cutterhead driving device for construction of tunnel machinery is provided, comprise permagnetic synchronous motor, reductor and planetary gear that order is connected.
In one embodiment, be provided with at least two by a permagnetic synchronous motor and the axial mechanism that reductor consists of, wherein each axial mechanism jointly acts on a planetary gear.
Needs as the case may be, reductor are three grades of reductors, double reduction machine or first class reducer.
In one embodiment, cutterhead driving device also comprises and is used to reductor that cooling water cooling plant or air cooling equipment is provided.Certainly, also cooling unit can be set, and by cooling heat radiation the naturally.
In a specific embodiment, permagnetic synchronous motor is 20 utmost points, and the speed reducing ratio of described reductor is i=30.
Comprising permagnetic synchronous motor, reductor and planetary cutterhead driving device according to of the present invention, number of poles by permagnetic synchronous motor is set to a lot, just can significantly reduce its output speed, thereby effectively reduced the input speed of reductor, reduced 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 brought thus joint space-efficient advantage.
In addition, reductor can adopt the nature type of cooling under normal circumstances, only needs to 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) the permanent magnet synchronous electric engine efficiency is high, and power factor is high, thereby has reduced energy consumption and running cost.
2) the 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, more is fit to the narrow and small requirement of shield body space of complete-section tunnel boring machine.
3) brand-new component combination mode makes whole driving device structure simple, easy to maintenance, and cost is low.
Description of drawings
Fig. 1 has shown according to cutterhead driving device of the present invention.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with a specific embodiment the present invention is elaborated.
As shown in Figure 1, the cutterhead driving device 10 according to this specific embodiment of the present invention especially can be used for complete-section tunnel boring machine.This cutterhead driving device 10 comprises permagnetic synchronous motor 1, reductor 2 and the planetary gear 3 that is 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, thereby consisted of two groups of axial mechanisms, they drive planetary gear 3 jointly, thereby drive the cutterhead of tunnel machine.Yet be appreciated that those skilled in the art can arrange according to the needs of actual conditions more groups of permagnetic synchronous motors 1 and reductor 2.
Number of poles by suitably selecting permagnetic synchronous motor 1 and the speed reducing ratio of reductor 2 can realize desired cutterhead rotating speed output.In a concrete example, permagnetic synchronous motor 1 is 20 utmost points, and its specified output speed is 300rpm.Simultaneously, 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.Due to the permagnetic synchronous motor 1 that has adopted 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 has just simplified the structure of existing complete-section tunnel boring machine cutterhead driving device greatly, has saved space and cost.
Abovely by the simplest a kind of cutterhead driving device, the present invention is had been described in detail, and with most typical data declaration beneficial effect of the present invention, this enables those skilled in the art to realize or use the present invention.Multiple modification to these embodiment will be apparent to one skilled in the art.General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
