Abstract
The utility model provides a cutter head driving device for tunnel engineering machinery. The cutter head driving device comprises permanent magnet synchronous motors, speed reducers and planet gears which are sequentially connected with one another. The cutter head driving device has the advantages that the number of poles of each permanent magnet synchronous motor is high, so that the output rotational speed of each permanent magnet synchronous motor can be obviously reduced, accordingly, the input rotational speed of each speed reducer is effectively reduced, and a speed reducing ratio and the number of speed reducing stages of each speed reducer are decreased.
Description
Technical field
The utility model relates to a kind of cutterhead driving device of construction of tunnel machinery, relates 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 the 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.First kind is to comprise hydraulic motor, reductor and planetary drives structure, and second kind 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 namely be to adopt hydraulic motor or variable-frequency motor, its output speed is all than higher, and the cutterhead rotating speed in the practical application is lower.This just requires the speed reducing ratio of reductor bigger, and reductor adopts two reduction gear at least, and need extra water cooling plant be its heat radiation.This finally cause these two kinds of drives structure take that volume is big, noise is high, heat radiation is bad.Simultaneously, the transmission efficiency of these two kinds of drives structure is low, financial cost is high.
The utility model content
The purpose of this utility model provides a kind of cutterhead driving device for construction of tunnel machinery, and it is energy-efficient, and is simple in structure, and cost is low.
According to the utility model, a kind of cutterhead driving device for construction of tunnel machinery is provided, comprise permagnetic synchronous motor, reductor and planetary gear that order links to each other.
In one embodiment, be provided with at least two by a permagnetic synchronous motor and the axial mechanism that reductor constitutes, 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 water cooling plant or the air cooling equipment that is used to reductor that cooling is provided.Certainly, also cooling unit can be set, and dispel the heat by cooling off naturally.
In a specific embodiment, permagnetic synchronous motor is 20 utmost points, and the speed reducing ratio of described reductor is i=30.
Comprising in permagnetic synchronous motor, reductor and the planetary cutterhead driving device according to described in the utility model, number of poles by permagnetic synchronous motor is set to a lot, just can significantly reduce its output speed, thereby reduced the input speed of reductor effectively, 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 the advantage of saving the space thus.
In addition, reductor under normal circumstances can adopt the nature type of cooling, only needs to adopt when overheated water-cooled or air cooling way.
Compared with prior art, the cutterhead driving device for construction of tunnel machinery provided by the utility model has following effect:
1) permagnetic synchronous motor efficient height, the power factor height, thus 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, the transmission efficiency height, and noise is little, and volume is little, is fit to the narrow and small requirement of shield body space of complete-section tunnel boring machine more.
3) brand-new parts compound mode makes that whole driving device structure is simple, and easy to maintenance, cost is low.
Description of drawings
Fig. 1 has shown according to cutterhead driving device of the present utility model.
The specific embodiment
Come the utility model is elaborated below with reference to the accompanying drawings and in conjunction with a specific embodiment.
As shown in Figure 1, the cutterhead driving device 10 according to this specific embodiment of the present utility model 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 links to each other successively.Wherein, the output shaft of permagnetic synchronous motor 1 links to each other with the input of reductor 2, and the output of reductor 2 links to each other with planetary gear 3.
In the present embodiment, be provided with two groups of permagnetic synchronous motors 1 and reductor 2, thereby constituted 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 more groups of permagnetic synchronous motors 1 and reductor 2 according to the needs of actual conditions.
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.Because adopted the permagnetic synchronous motor 1 of the big torque of the slow-speed of revolution, speed reducing ratio and the input speed of reductor 2 all reduce.Therefore, reductor 2 can adopt the first class reducer structure, 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.
More than by the simplest a kind of cutterhead driving device the utility model is had been described in detail, and with most typical data declaration the beneficial effects of the utility model, this enables those skilled in the art to realize or uses the utility model.Multiple modification to these embodiment will be apparent to one skilled in the art.Defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
