Detailed description of the invention
For the features described above of the present invention and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing, make in detail
Carefully it is described as follows, but the present invention is not limited to this.
Referring to figs. 1 to Fig. 5
The motor-operating mechanism of a kind of direct-acting three-working-position isolation, including mounting bracket 10, described mounting bracket side sets
It is equipped with controller 20 and is positioned at the driving motor 30 on the upside of controller, the motor output shaft 40 driving motor of described driving motor
On be provided with axially extending bore 41, described axially extending bore internal messing has the unilateral bearing 50 that a pair installation direction is contrary, described unidirectional
It is equipped with the power transmission shaft 60 that outfan passes from mounting bracket opposite side in bearing, the outfan of described power transmission shaft is provided with use
In the output shaft 70 being connected with gear-driven assembly, described output shaft is provided with for driving cutting of power transmission shaft transverse shifting
Hand-off handle 80, described mounting bracket is additionally provided with the rotary encoder being connected with another synchronism output axle through bonder 91
90。
In the present embodiment, described mounting bracket includes two longitudinally disposed plate bodys 11, and the perimembranous of described two plate bodys is through connecting
Bar 12 is connected, and the opposite side perimembranous of mounting bracket is also arranged at intervals with the second connecting rod 13 being connected with disconnecting switch, institute
State motor output shaft to be installed between two plate bodys.
In the present embodiment, described driving motor can be direct current generator, and the outfan of described direct current generator is through gear driving pair
Or belt gear is connected with motor output shaft, thus motor output shaft is driven to rotate.
In the present embodiment, between a pair unilateral bearing, it is provided with fairlead 42 in described axially extending bore, in order to complete
The axial limiting of a pair unilateral bearing.Described power transmission shaft penetrates the end of unilateral bearing and is provided with external diameter less than unilateral bearing internal diameter
Annular recess 61, and this end passes the plate body of mounting bracket side, in order to be connected with manual-operating mechanism.
In the present embodiment, described output sleeve is placed on the outfan of power transmission shaft, and described switching taper knob is placed in output shaft
On the end being connected with power transmission shaft, and axially disposed on the end that is connected with power transmission shaft of output shaft there are elongated slot 71, a limit
Position pin 81 is connected through switching handle and elongated slot with output shaft, thus is completed transverse shifting and the band of power transmission shaft by spacer pin
Dynamic output shaft axial rotation.
In the present embodiment, it is additionally provided with one end in described output shaft and is placed on power transmission shaft outfan and offsets with spacer pin
The back-moving spring 72 connect, in order to the active force being moved to the left is provided for power transmission shaft.
In the present embodiment, the most axially arranged connecting hole 73 having square shape on the outfan of described output shaft.
In the present embodiment, controller is with motor overload defencive function: during electric operating, after mechanism puts in place, as
Really rotary encoder coordinates wrong with controller, and motor is the most charged rotates output, but it is limited by stopping means in mechanism,
Load is notable to strengthen, and motor working current is detected by controller, and when its numerical value is greatly to a setting limit value, controller is by motor
Stop operating.
A kind of using method of the motor-operating mechanism of direct-acting three-working-position isolation, step is as follows:
1) electronic manipulation: under normal circumstances, can electric operating, back-moving spring heads on spacer pin and makes power transmission shaft and two one-way shaft
Accept and touch.Controller is when receiving the combined floodgate of outside transmission, isolation or ground connection order, and controller controls to drive electric machine rotation, by
In unilateral bearing is engaged on the axially extending bore of motor output shaft so that one of them unilateral bearing is defeated with the motor driving motor
Shaft rotates, thus drives power transmission shaft and output shaft rotation, and final driven gear transmission component, another unilateral bearing is then in
Idling conditions.Otherwise driven output shaft by the unilateral bearing dallied before.While output shaft driven gear drive disk assembly, logical
The rotational angle of gear-driven assembly is sampled by the transmission from one meridian to another bonder rotary encoder that is connected with controller, and feeds back to control
Device, in order to when the contact of disconnecting switch is close to required operating position, the number of turns that rotary encoder sampling obtains also is up to
The predetermined amount converted according to real work position, now decelerating through motor stops, thus reduces " the drift of contact as far as possible
Move "；
2) manual manipulation: use an operation handle to make switching handle move to output shaft direction so that back-moving spring compresses, switching
Handle drives power transmission shaft to leave the constraint of unilateral bearing, now Continued depression rotating operation handle, so that output shaft rotation,
And then driven gear transmission component rotates.
The foregoing is only presently preferred embodiments of the present invention, for the ordinary skill in the art, according to this
Bright teaching, the motor-operating mechanism of the direct-acting three-working-position isolation designing multi-form is not required to the labor of creativeness
Dynamic, the most all equalizations done according to scope of the present invention patent change, repair
Change, replace and modification, all should belong to the covering scope of the present invention.
