The operation principle of the present invention is that:
Manual drive mode:
Staff pull-up pull ring 3a simultaneously catches handle 7 and pulls shaft 2 to the left, is pulled to right limit plate and when cabinet 1 contacts
It then pulls in place, unclamps pull ring 3a, lock pin 3b falls under reset spring 3c effect and falls into the engaging groove 4 in left side, with this
Meanwhile vertical bevel gear 10 is moved to the left and engages with lateral bevel gear 11, at this point, the present invention is in manual drive mode；
Braking process: the steel wire loop of brake shoe is controlled on hanging wheel 22, staff shakes rocking bar, shaft 2 in the counterclockwise direction
Vertical bevel gear 10 is driven to rotate, vertical bevel gear 10 engages lateral bevel gear 11 and lower section screw rod 15 is driven to rotate clockwise,
Silk braid 19 is risen by the transmission effect with screw rod 15, and guide wheel drives wirerope to tense, and is braked when silk braid 19 rises to top
When the opposite position of sensors in place 14, braking sensors in place 14 detects the sensor block 18 on silk braid 19 and to central processing
Module sends high level signal, and central processing module controls alarm and issues alarm signal, and staff stops shaking, brake
At.
Alleviation process: staff shakes rocking bar along clockwise direction, and shaft 2 drives vertical bevel gear 10 to rotate, vertically
Bevel gear 10 engages lateral bevel gear 11 and lower section screw rod 15 is driven to rotate counterclockwise, and silk braid 19 is made by the transmission with screw rod 15
With decline, under the decline effect of silk braid 19, guide wheel drives steel wire rope looseness, alleviates in place when silk braid 19 drops to corresponding lower section
When the position of sensor 16, alleviates sensors in place 16 and detect the sensor block 18 on silk braid 19 and sent to central processing module
High level signal, central processing module control alarm equipment alarm, and staff stops shaking, alleviates and complete.
Automatic drive mode:
Staff pull-up pull ring 3a simultaneously catches handle 7 to push shaft 2 to the right, is pushed into then to push away when left limit plate is contacted with cabinet
It moves in place, in the separating tank 5 that release pull ring 3a, lock pin 3b fell and dropped down onto right side under reset spring 3c effect, at the same time,
Vertical bevel gear 10 moves right and separates with lateral bevel gear 11, at this point, the present invention is in automatic drive mode.
Braking process: the steel wire loop of brake shoe is controlled on hanging wheel 22, when needing to brake, staff passes through control panel
Control interface Deng connection central processing module carries out a key manipulation, and it is counterclockwise that central processing module controls brshless DC motor 28
Rotation, the driving force of brshless DC motor 28 are transmitted on screw rod 15 after the three-level decelerating effect of train of reduction gears 12, screw rod
15 along rotating clockwise, and silk braid 19 rises and tense wire rope carries out braking maneuver, passes in place when silk braid 19 rises to braking
When the opposite height of sensor 14, braking sensors in place 14 detects the sensor block 18 on silk braid 19 and sends out to central processing module
High level signal is sent, central processing module control brshless DC motor 28 stops operating, at the same time, and alarm equipment alarm, braking
It completes；
If braking sensors in place 14 to fail, silk braid 19 continues to rise after reaching braking 14 position of sensors in place, rises to
When limes superiors 13 position of microswitch, limes superiors microswitch 13 sends high level signal, central processing to central processing module
Module control brshless DC motor 28 stops operating, and at the same time, alarm equipment alarm, braking is completed；
Alleviation process: staff carries out a key manipulation by the control interface that control panel etc. connects central processing module, in
Centre processing module control brshless DC motor 28 rotates clockwise, the driving force of brshless DC motor 28 through train of reduction gears 12 into
It is transmitted on screw rod 15 after row three-level decelerating effect, screw rod 15 rotates counterclockwise, and silk braid 19 declines and drives wirerope gradually
Relaxation carries out alleviation movement, when silk braid 19 drops to the height opposite with sensors in place 16 is alleviated, alleviates sensors in place
16 detect the sensor block 18 on silk braid 19 and send high level signal to central processing module, and central processing module control is brushless
Direct current generator 28 stops operating, and at the same time, alarm equipment alarm is alleviated and completed；
It fails if alleviating sensors in place 16, silk braid 19 continues to decline after reaching alleviation 16 position of sensors in place, is down to
When limit inferior 17 position of microswitch, limit inferior microswitch 17 sends high level signal, central processing to central processing module
Module control brshless DC motor 28 stops operating, and at the same time, alarm equipment alarm, braking is completed.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that, still may be used
To modify to technical solution documented by previous embodiment, or some or all of the technical features are equal
