Abstract
An anti-falling safety device for a building construction elevator comprises a control mechanism and an anti-falling mechanism. The anti-falling safety device has the advantages of being simple in structure, ensuring personal safety of constructors and reducing accidents that the construction elevator falls. The anti-falling safety device can be modified base on an existing construction elevator.
Description
Technical field
The utility model relates to building operation elevator technology field, a kind of specifically building operation elevator falling-proof safety device.
Background technology
Continuous development along with urban construction; Skyscraper is on the increase; Building operation elevator thereby be widely used, it is inseparable with workmen's productive life as the service tool of vertical operation in the skyscraper, but in a single day the building operation elevator has an accident, when falling rapidly; To produce harm greatly even the safety that jeopardizes property, life to workmen's physical and mental health.
Elevator brake or safety tongs (being safety device) are installed in the existing building operation elevator, and most building operation elevator device all can there be a bumper of fixing with ground in the hoistway bottom.When down falling rapidly at et out of order, the safety device in the building operation elevator is opened, and it can pin the elevator of up-and-down movement in hoistway; When elevator dropped down onto the hoistway bottom, the bumper that fixes on the ground can play certain buffer action, even so; Some building operation elevator is in bad repair with age; Elevator safety device loses effect, and the buffer action that the bumper that fixes on the ground can play is also limited, and personal safety is brought threat.
The utility model content
To be that design is a kind of can make the construction elevator safe operation to the purpose of the utility model under the situation that original safety device lost efficacy, and improves a kind of building operation elevator falling-proof safety device of construction elevator safety factor.
A kind of building operation elevator of the utility model falling-proof safety device comprises control mechanism and safety dropping prevent mechanism; It is characterized in that: control mechanism comprises that one on spring in the insulating cylinder links to each other with the fixed mount that insulate; The other end of spring links to each other with prill; Conducting film is equipped with on the first half bulkhead both sides of insulating cylinder; Conducting film is connected with power supply with lead on one side, and the conducting film of another side is connected with the motor of lead and safety dropping prevent mechanism; Safety dropping prevent mechanism comprises: be fixed on the buffer rack of top, outside, construction elevator room and be fixed on the ejector on the slideway.
Ejector comprises: pin that is equipped with and the spring that is with on motor and the turning cylinder that motor links to each other, and one of spring with turning cylinder one links to each other, and the other end of spring links to each other with the bracing frame of turning cylinder.
Buffer rack comprises: be fixed on the connection support flexible shelves post continuous with being connected support of top, outside, construction elevator room, flexible shelves post is high-intensity rubber column or high-intensity nylon rope post.
A kind of building operation elevator of the utility model falling-proof safety device is achieved in that bead was in state of weightlessness when construction elevator fell rapidly, rises to the conducting film place of insulating cylinder; Switch on, the electric motor starting running drives turning cylinder and rotates; Be contained in the pin on the turning cylinder; Move to and the previous status upright position, the flexible shelves post of buffer rack is fallen on the pin, and construction elevator slows down until stopping; Behind the static trouble-shooting of construction elevator, bead comes back to and receives gravity state, breaks away from conducting film, and circuit breaks off; The motor of all the other floors cuts out, and pin is return under the effect of spring, as long as construction elevator starts; Support pin return under the effect of spring of construction elevator, construction elevator can recover normal operation, when construction elevator drops; If certain one deck is not because the time difference is blocked, following one deck is bound to block, and has improved the safety control coefficient.
The advantage of a kind of building operation elevator of the utility model falling-proof safety device is: simple in structure, can on existing construction elevator basis, transform, and need not increase very big cost, ensure workmen's personal safety, reduce the generation of construction elevator falling accident.
Description of drawings
The structural representation of Fig. 1, a kind of building operation elevator of the utility model falling-proof safety device.
The specific embodiment
Shown in accompanying drawing, a kind of building operation elevator of the utility model falling-proof safety device, the specific embodiment is:
A kind of building operation elevator falling-proof safety device comprises: control setup 1 and anti-fall device 2.
Anti-fall device 2; Comprise: the buffer rack 9 that is fixed on below, outside, elevator room; Be fixed on the ejector 10 on the slideway; Ejector 10 comprises: pin 11 that is equipped with and the spring 12 that is with on motor 8 and the turning cylinder 13 that motor 8 links to each other, and one of spring 12 with turning cylinder 13 one links to each other, and the other end of spring 12 links to each other with the bracing frame of turning cylinder 13.
Buffer rack 9 comprises: the connection support 14 that is fixed on outside, elevator room top with is connected the flexibility grade post 15 that support 14 links to each other.
Claims (3)
