Description
Technical field
Shield machine field is the utility model is related to, more specifically to a kind of cutter drive system of shield machine.
Background technology
Cutter head of shield machine driving typically uses hydraulic driving mode or master-slave control method, and hydraulic driving mode exists following
Shortcoming：1st, the Hydraulic Elements accuracy of manufacture requires high, and assembling is relatively difficult, and working service is stricter；2nd, fluid easily pollutes, oil
After liquid pollution, the reliability of system work can be influenceed；3rd, break down and be not easy to check and exclude.In master-slave control method from change
The operating frequency change of frequency device always lags behind primary transducer, so as to so that primary transducer and starting or stoping from frequency converter
It is asynchronous.So, the mechanical gear of cutterhead starts in cutterhead in the motor-driven shield machine that can be connected with primary transducer
Independent stress when startup, thus, mechanical gear load and the discontinuity of cutterhead in shield machine can be caused, is ultimately resulted in
Its service life is influenceed because of the serious wear of the mechanical gear.
Utility model content
In order to overcome the disadvantages mentioned above of cutter drive system of shield machine in the prior art, the utility model provides a kind of shield
Structure machine knife disc driving system, including：PLC, motor, frequency converter group, decelerator, base bearing, sealing lubricating arrangement, become
Frequency device group be arranged on rear chassis on, be connected by CC-Link buses with PLC, cutter plate driver by base bearing external tooth
Circle is connected by adpting flange high-strength bolt with cutterhead, and cutterhead cylinder sets sealing lubricating arrangement, and motor passes through
Decelerator drives cutterhead, and frequency converter corresponds with motor, and motor and frequency converter are 8, and frequency converter passes through electric power electricity
Cable is connected with motor, and the parallel control structure of a motor is dragged using a frequency converter, and every motor is born
It is identical to carry characteristic.
Further, motor is synchronous motor.
Further, motor rounded distribution on cutterhead is set.
The utility model has the advantages that：Functional reliability can be improved, makes maintenance easy；The synchronous operation of frequency converter simultaneously
Or stop causing synchronizing motors and stopping, so that the mechanical gear of cutterhead is in electric motor starting or stopping in shield machine
When, load and uniform force, so as to extend the service life of equipment.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the utility model drive system theory diagram.
Fig. 2 is the position distribution schematic diagram of motor in the utility model.
Embodiment
To make the technical solution of the utility model and advantage clearer, the utility model is implemented below in conjunction with accompanying drawing
Mode is described in further detail.Unless otherwise defined, all technical terms used in the utility model embodiment are respectively provided with
The identical implication being generally understood that with those skilled in the art.
Cutter drive system of shield machine of the present utility model, including：PLC, motor, frequency converter group, decelerator,
Base bearing, sealing lubricating arrangement.Frequency converter group is arranged on the chassis of rear, and cutter plate driver passes through connection by the external toothing of base bearing
Flange high-strength bolt is connected with cutterhead, and cutterhead cylinder sets sealing lubricating arrangement, and motor is driven by decelerator
Cutterhead.
As shown in figure 1, PLC is connected by CC-Link buses with frequency converter, CC-Link is as in current industry
The bus-network of most high speed, can transmit substantial amounts of shield machine and rear auxiliary facility at high speed includes switching signal, mould
The data such as analog quantity information.Frequency converter is corresponded with motor, and frequency converter is connected by power cable with motor, using one
Frequency converter drags the parallel control structure of a motor, and the load characteristic of every motor is identical, and motor and frequency converter are equal
For 8.Specifically, motor 1 and frequency converter 1 ' connect, motor 2 and frequency converter 2 ' connect, and motor 3 and frequency converter 3 ' are even
Connect, motor 4 and frequency converter 4 ' connect, and motor 5 and frequency converter 5 ' connect, and motor 6 and frequency converter 6 ' connect, motor 7
Connected with frequency converter 7 ', motor 8 and frequency converter 8 ' connect.
As shown in Fig. 2 motor rounded distribution on cutterhead is set.
It is described above to be for only for ease of it will be understood by those skilled in the art that the technical solution of the utility model, not to
Limit the utility model.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc.,
It should be included within the scope of protection of the utility model.
