Brief description of the drawings
Fig. 1 is the theory diagram of anti-falling apparatus of elevator in one embodiment provided by the utility model.
Fig. 2 is the circuit connection diagram of brake in one embodiment provided by the utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description, but the utility model
Protection domain be not limited to it is as described below.
As shown in figure 1, be the theory diagram of anti-falling apparatus of elevator in one embodiment provided by the utility model,
Brake YB in the governor circuit, first switch, second switch and the brake apparatus that are connected including power supply, with main drive,
First output end of the control terminal connection governor circuit of first switch, the second of the control terminal connection governor circuit of second switch are defeated
Go out end, the first motion end connection power supply of first switch, the first action of the second motion end connection second switch of first switch
End, the second motion end connecting brake YB of second switch.
First switch and second switch action are consistent during work, and when equipment main drive obtains electric work, first opens
Close and second switch simultaneously it is electric, brake YB obtains electric, and brake YB is in releasing orientation, and equipment can move up and down；Equipment
When main drive power-off is stopped, first switch and second switch power off simultaneously, and brake YB is in power-off holding state,
Make equipment stop motion, realize that equipment is stopped equipment effective brake in main drive by such a mode, will not occur
Device fall accident；Using two switches of first switch and second switch in the design, when first switch or second switch occur
When mechanical clamping or sticky point cause to power off, second switch or first switch are powered off, and hold brake YB power-off tightly, really
Protect equipment and falling accident do not occur, prevented with this because mechanical clamping occurs for breaker or sticky point causes the accident of device fall,
Improve the safety coefficient that equipment uses.
In one embodiment of the present utility model, anti-falling apparatus of elevator also includes detection circuit and alarm, inspection
Slowdown monitoring circuit connects first switch and second switch respectively, for detecting first switch and second switch state, alarm connection inspection
Slowdown monitoring circuit.
During work, after the power-off of equipment main drive is stopped, electric circuit inspection first switch output end and second is detected
Output switching terminal contacts status, when any one contact is in the conduction state in first switch output end and second switch output end
When, the alarm of connection detection circuit is alarmed；Because apparatus logic needs, when equipment main drive powers off, first
Switch and second switch need synchronous power-off, therefore first switch and the output end of second switch should be at off-state, now
First switch and second switch output end are in the conduction state, illustrate that first switch and second switch break down, alarm report
Police notifies staff to be repaired in time, ensures the safe handling of equipment.
In one embodiment of the present utility model, alarm includes buzzer and flash lamp, due to equipment working environment noise
Miscellaneous, single audible alarm cannot ensure that staff receives warning message, and the design reaches sound using buzzer and flash lamp
The same alarm of light, the effective percentage of alarm is improved with this.
In one embodiment of the present utility model, first switch is contactor or relay, second switch be contactor or
Relay.
As shown in Fig. 2 it is the circuit connection diagram of brake in one embodiment provided by the utility model, in the present embodiment
First switch and second switch select contactor, respectively contactor KM1 and contactor KM2, contactor KM1 input and
Contactor KM2 input connects the first output end and the second output end of governor circuit respectively, and contactor KM1 input connects
Meet power supply, contactor KM1 output end connection contactor KM2 input, contactor KM2 output end connecting brake YB.
During work, the power-off of equipment main drive needs brake YB power-off holding to prevent equipment high-altitude from falling when being stopped
Fall, now governor circuit control contactor KM1 and contactor KM2 power-off, now has in timely contactor KM1 and contactor KM2
One contactor breaks down and can not powered off, because contactor KM1, contactor KM2, brake YB and power sources in series are in same electricity
Lu Zhong, as long as brake YB power-off can be achieved in contactor KM1 and the power-off of any one contactor of contactor KM2, held tightly,
Preventing equipment falling from high altitude, such a design, which can avoid contact with device and break down, can not power off the accident for causing equipment falling from high altitude,
Improve equipment coefficient safe to use.
In one embodiment of the present utility model, the first output end is located at the different control of governor circuit with the second output end
In circuit, due to the first output end of contactor KM1 connection governor circuits, the second output of contactor KM2 connection governor circuits
End, contactor KM1 and contactor KM2, which are connected in different control circuits, prevents control circuit breaks down from causing contactor
KM1 and contactor KM2 while failure phenomenon, the stability to be worked with this strengthening system.
By the high-altitude of transducer drive connect volume tray apparatus exemplified by, wherein contactor KM1 connections frequency converter export switch
Control point is measured, and contactor KM2 connections PLC controls the digital output modul point of output, it is ensured that contactor KM1 and contactor KM2 are not
It can fail simultaneously.During normal work, contactor KM1 and contactor KM2 synchronization actions, alarm do not work, as contactor KM1
（KM2）When generation mechanical clamping or sticky point failure, on the one hand, contactor KM2 (KM1) still can be avoided with normal work
Dynamo-electric brake YB can not be powered off and be caused main drive equipment stall to fall during braking, on the other hand, detect electric circuit inspection
Contactor KM1 and contactor KM2 can show different machine performances when main drive is shut down, and alarm is alarmed,
Remind operator to have electric fault in time, can repair immediately.Thus thoroughly prevent equipment falling from high altitude security incident
Generation.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
