Abstract
A kind of elevator system stop device interlocking protective device, is characterized in that, comprise hall sensing switch, relay, power supply, hoister control system, gig, indicator lamp; Hall sensing switch one termination 24V power supply, ground connection after other end series relay, connect the power input of hoister control system after power sources in series relay normally open contact, the control signal mouth of hoister control system connects gig, and indicator lamp is connected in parallel on the two ends of relay; Hall sensing switch is arranged on stop device, and the action with the motion of stop device, whether recover to put in place for Real-Time Monitoring stop device, after stop device recovery puts in place, hall sensing switch closes; Whether indicator lamp is used to indicate stop device and recovers to put in place; Relay is for controlling the power on/off of hoister control system; Hoister control system is for controlling the lifting of gig; The utility model achieves the interlock protection of elevator system and stop device.
Description
Technical field
The utility model relates to mine safety field, particularly a kind of elevator system stop device interlocking protective device.
Background technology
Current industrial and mineral mine generally ingate stop device all do not carry out interlocked control with lifting electric-control system, stop device does not recover to put in place or malfunctioning lifting electric-control system can't detect, and there is certain safety hazard; This just needs a kind of device that can realize elevator system, stop device interlock protection badly, guarantees the safe operation under mine.
Utility model content
The purpose of this utility model is to provide a kind of elevator system stop device interlocking protective device, for realizing the interlock protection of elevator system, stop device, thus ensures the safe operation under mine.
A kind of elevator system stop device interlocking protective device, is characterized in that, comprise hall sensing switch, relay, power supply, hoister control system, gig, indicator lamp; Hall sensing switch one termination 24V power supply, ground connection after other end series relay, connect the power input of hoister control system after power sources in series relay normally open contact, the control signal mouth of hoister control system connects gig, and indicator lamp is connected in parallel on the two ends of relay;
Hall sensing switch is arranged on stop device, and the action with the motion of stop device, whether recover to put in place for Real-Time Monitoring stop device, after stop device recovery puts in place, hall sensing switch closes; Whether indicator lamp is used to indicate stop device and recovers to put in place;
Relay is for controlling the power on/off of hoister control system; Hoister control system is for controlling the lifting of gig.
Elevator system stop device fender guard of the present utility model, also comprise relay normally closed contact, annunciator, relay normally closed contact is connected between hoister control system and annunciator.
The beneficial effects of the utility model are the interlock protection achieved between elevator system and stop device, thus ensure that the safety of borehole operation.
Below in conjunction with accompanying drawing, elevator system stop device interlocking protective device of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is elevator system stop device interlocking protective device schematic diagram.
Detailed description of the invention
As shown in Figure 1, elevator system stop device interlocking protective device of the present utility model comprises hall sensing switch, relay K, power supply, hoister control system, gig, indicator lamp L; Hall sensing switch one termination 24V power supply, ground connection after other end series relay K, connect the power input of hoister control system after power sources in series relay normally open contact K-1, the control signal mouth of hoister control system connects gig, and indicator lamp L is connected in parallel on the two ends of relay K;
Hall sensing switch is arranged on stop device, and the action with the motion of stop device, whether recover to put in place for Real-Time Monitoring stop device, after stop device recovery puts in place, hall sensing switch closes, when stop device does not recover to put in place, hall sensing switch is in off-state; Whether indicator lamp L is used to indicate stop device and recovers to put in place, shows that stop device has recovered to put in place when indicator lamp L is bright, shows that stop device does not recover to put in place when indicator lamp L does not work;
Relay K is for controlling the power on/off of hoister control system; Hoister control system is for controlling the lifting of gig.
In practical application, when stop device recovers to put in place, hall sensing switch closes, relay K is energized, indicator lamp L is lit, relay normally open contact K-1 closes, and connect the connection of hoister control system and power supply, now staff is effective by the control of hoister control system to the lifting of gig;
When stop device does not recover to put in place; hall sensing switch disconnects; relay K no power; indicator lamp does not work; relay normally open contact K-1 is in off-state; hoister control system is in off-position, and now staff is invalid by the control of hoister control system to the lifting of gig, namely achieves the interlock protection of elevator system and stop device.
Above-mentioned be embodiment basis on, elevator system stop device interlocking protective device of the present utility model, also comprises relay normally closed contact K-2, annunciator, and relay normally closed contact K-2 is connected between hoister control system and annunciator.When stop device does not recover to put in place, hall sensing switch disconnects, relay K no power, relay normally closed contact is in closure state, at this moment, if staff is invalid by the control of hoister control system to the lifting of gig, hoister control system sends alerting signal simultaneously, by relay normally closed contact K-2, drive alarm equipment alarm, prompting staff stop device does not recover to put in place.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
