Abstract
The utility model discloses an interlock of material hoist guard gate, including the lock shell, the lock shell is fixed on the gatepost of end one side is opened and close to the guard gate, still includes through bolt fastening activity hasp on the lock shell, sets up insulating box and insulating telescopic ejector rod in the lock shell, is equipped with the spring in the insulating box to reach the circuit contact that communicates with material hoist, the spring is connected with insulating telescopic ejector rod, and insulation telescopic ejector rod sets up with the material hoist guard gate outside extending the lock shell relatively. This interlock simple structure, practicality only can ensure that the lifting machine can move under the condition that the guard gate closed, have improved the security performance of guard gate to reduced that operation personnel take place highly to weigh down, mechanical injury's probability.
Description
Technical field
The utility model relates to the protective device that construction floor faces limit, specifically a kind of interlock system coordinating material elevator protective door.
Background technology
At present; discharging platform between construction floor and material elevator is arranged together movable security door to protect the life security of workmen; protective door forms combined control system by the electric system of travel switch and material elevator; when protective door is closed; protective door frame promotes travel switch, and make circuit ON, the latch of door leaf is plugged by operating personal; make material lifting machine circuit maintain closure state while locking protective door, gig can normally be run.Because operator's awareness of safety of part camp site is thin, for seeking convenient saving trouble of doing manual work, directly travel switch is placed in closure state and does not close protective door, run under the environment that gig is not closed at each floor, operating personnel is caused habitually in dangerous region, to wait for gig, or erect-position is pressed close to floor edge and pop one's head in look around, therefore cause having occurred many height pendants, the event of mechanical wounding.
Summary of the invention
In order to ensure safety in production, stop to operate against regulations, the utility model provides a kind of interlock system of material elevator protective door, this device can guarantee that only gig can run when protective door closes, improve the safety performance of protective door, thus reduce the probability that high pendant, mechanical wounding occur operating personnel.
The technical scheme realizing the utility model object is:
A kind of interlock system of material elevator protective door, comprise lock housing, lock housing is fixed on protective door and opens and closes on the door pillar of end side, also comprise and be bolted on movable snap in lock housing, be arranged on the insulation booth in lock housing and insulating telescopic push rod, in insulation booth, be provided with spring, and the line contact to be communicated with material elevator, spring is connected with insulating telescopic push rod, and insulating telescopic push rod extends outside lock housing, is oppositely arranged with material elevator protective door.
Described movable snap, can 180 ° of rotations in " 7 " font.
Steel plate washer is provided with between described spring and insulating telescopic push rod.
When protective door closes, insulating telescopic push rod advances in press-in insulation booth by spring by protective door, now steel plate washer contact line contact makes gig circuit close, movable snap is left behind and is fastened protective door by operating personnel simultaneously, now protective door is in the state of closing, and gig circuit is channel status and normal operation.
When gig arrives operation floor, operating personnel pulls open movable snap, insulating telescopic push rod is released by spring, steel plate washer departs from line contact, now protective door is opened, and gig circuit is in off state, and gig is out of service, before operating personnel closes protective door, gig cannot start.
The beneficial effects of the utility model are: this interlock structure is simple, practical, can guarantee that only gig can run when protective door closes, improve the safety performance of protective door, thus reduce the probability that high pendant, mechanical wounding occur operating personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is assembling of the present utility model application schematic diagram.
In figure, 1. interlock system 2. protective door 3. lock housing 4. insulating telescopic push rod 5. steel plate washer 6. spring 7. contact 8. movable snap 9. insulation booth 10. door pillar.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model content is described further, but is not to restriction of the present utility model.
With reference to Fig. 1-2, a kind of interlock system of material elevator protective door, comprise lock housing 3, lock housing 3 is fixed on protective door 2 and opens and closes on the door pillar 10 of end side, also comprises and is bolted on movable snap 8 in lock housing 3, be arranged on the insulation booth 9 in lock housing 3 and insulating telescopic push rod 4, spring 6 is provided with in insulation booth 9, and the line contact 7 be communicated with material elevator, spring 6 is connected with insulating telescopic push rod 4, insulating telescopic push rod 4 extends outside lock housing 3, is oppositely arranged with material elevator protective door 2.
Described movable snap 8, can 180 ° of rotations in " 7 " font.
Steel plate washer 5 is provided with between described spring 6 and insulating telescopic push rod 4.
When protective door 2 closes, insulating telescopic push rod 4 advances in press-in insulation booth 9 by spring 6 by protective door 2, now steel plate washer 5 contact line contact 7 make gig circuit close, movable snap 8 is left behind and is fastened protective door 2 by operating personnel simultaneously, now protective door 2 is in the state of closing, and gig circuit is channel status and normal operation.
When gig arrives operation floor, operating personnel pulls open movable snap 8, insulating telescopic push rod 4 is released by spring 6, steel plate washer 5 departs from line contact 7, now protective door 2 is opened, and gig circuit is in off state, and gig is out of service, before operating personnel closes protective door 2, gig cannot start.Only when protective door 2 closes, gig can run, and improves the safety performance of protective door 2 to use this interlock system to guarantee, thus reduces the probability that high pendant, mechanical wounding occur operating personnel.
