Abstract
The invention discloses an elevator cage flat-layer-falling prevention device in linkage with a door motor. The prevention device comprises two linkage structures which are respectively mounted at the two sides of the top of an elevator cage and are in linkage with the elevator door motor, wherein two cage top limiting switches which are respectively in contact with the linkage structures are further mounted at the top of the elevator cage and are connected into a control system; an inserted pin is fixed at the front end of each linkage structure, an inserted pin limiting switch is further arranged on each inserted pin, inserted pin holes are formed in a hoistway where an elevator is located, the inserted pins and the inserted pin holes are in position level under the condition that the elevator is in a flat layer state, and the inserted pin limiting switches are connected into a safety circuit. According to the prevention device, a whole set of mechanical structures and electrical linkages, which are related to the door motor and a cage, is adopted, the cage can be prevented from falling during falling due to the mechanical structures, and due to the electrical linkage, whether the structures are in a working state or not can be monitored and the safety circuit can be disconnected during falling, so that the problem that the cage accidentally falls in the flat layer state can be effectively solved.
Description
Technical field
the present invention relates to an elevator cabin flat level a kind of and door machine interlock the holdout device that falls.
Background technology
at present elevator when flat bed turnover passenger to car because the situation of a series of reasons tenesmus does not have actv., perfect solution.This device can when this situation occurs, effectively avoid passenger's injures and deaths and device impaired.
Summary of the invention
the present invention seeks to: a kind of failure-free, easy to maintenance, the lift car holdout device that falls are cheaply provided.
technical scheme of the present invention is:
an elevator cabin flat level a kind of and door machine interlock the holdout device that falls, whether described elevator is controlled and is moved by safety return circuit by control system, described holdout device comprises two linkage structures that are installed on respectively elevator car top both sides and link with elevator door-motor, two sedan-chair top limit switches that contact with linkage structure respectively are also installed, described sedan-chair top limit switch access control system on described elevator car top; Described linkage structure front end is fixed with respectively a latch, on described latch, be also provided with a latch limit switch, in the hoistway at elevator place, pin hole is installed, under Elevator landing state, described latch is concordant with pin hole position, described latch limit switch access security loop.
concrete, described latch limit switch uses normally closed point, and described pin hole is U-shaped hole.
concrete, described sedan-chair top limit switch uses normal battle.
advantage of the present invention is:
1. the elevator cabin flat level provided by the present invention holdout device that falls, adopt a whole set of physical construction relevant with car to door machine and electric-linked, physical construction can stop car to fall in tenesmus process, whether electric-linked this structure of can monitoring is in running order and can break safety return circuit in tenesmus process, can effectively solve car in the accidental falling problem of flat bed state;
2. the present invention can select place of erection according to hoistway actual conditions, increases or reduce the size of latch, flexible for installation simple and easy;
3. the present invention is easy to maintenance, and cost is lower, makes apparatus for controlling elevator more reliable, perfect.

in figure, 1, car; 2, door machine; 3, linkage structure; 4, sedan-chair top limit switch; 5, latch; 6, pin hole; 7, latch limit switch.
The specific embodiment
as illustrated in fig. 1 and 2, the disclosed elevator cabin flat level holdout device that falls, comprise two linkage structures 3 that are installed on respectively lift car 1 sedan-chair both sides, top and link with elevator door-motor 2, two sedan-chair top limit switches 4 that contact with linkage structure respectively are also installed on described elevator car top, described sedan-chair top limit switch 4 uses normal battle, access control system, elevator need could operate when sedan-chair top limit switch 4 is oppressed; Described linkage structure front end is fixed with respectively a latch 5, and pin hole 6 is installed in the hoistway at elevator place, and under Elevator landing state, described latch is concordant with pin hole 6 positions.
as shown in Figures 4 and 5, on described latch 5, be also provided with a latch limit switch 7, described latch limit switch access security loop, latch limit switch uses normally closed point, and described pin hole is U-shaped hole.When elevator is in flat bed state and open the door while allowing passenger enter, by the linkage structure 3 between door machine 2 and latch 5, when door machine opens the door, latch 5 enters pin hole 6, and the latch limit switch 7 on latch 5 is not got to by pin hole 6, the sedan-chair top limit switch 4 that is simultaneously installed on sedan-chair top feeds back to this device of control system and has entered mode of operation under the effect of linkage structure.
as shown in Figures 6 and 7, when car is opening the door and during accidental falling, latch 5 falls to prevent car with the mutual locking of pin hole 6, and the latch limit switch 7 on latch plays the effect of disconnection safety return circuit because touching pin hole.
as shown in Figure 3, for electrical schematic diagram of the present invention, in figure, K switch 1, K2 and K3 are respectively above-mentioned two sedan-chair top limit switches 4 and latch limit switch 7, K switch 1, K2 are long normal open switch, when elevator door-motor 2 starts, under the effect of linkage structure, K switch 1, K2 closure, feed back to this device of control system and entered mode of operation; K switch 3 is normally closed switch, does not contact pin hole 6 when car is normal, and when car surprisingly drops, K switch 3 contact pin holes disconnect safety return circuit simultaneously.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All modifications that the Spirit Essence of main technical schemes is done according to the present invention, within all should being encompassed in protection scope of the present invention.
