Description
Technical field
the utility model 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 utility model object is: a kind of failure-free, easy to maintenance, the lift car holdout device that falls are cheaply provided.
the technical solution of the utility model 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.
the utility model has the advantages that:
1. the elevator cabin flat level provided by the utility model 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 utility model can be selected place of erection according to hoistway actual conditions, increases or reduce the size of latch, flexible for installation simple and easy;
3. the utility model is easy to maintenance, and cost is lower, makes apparatus for controlling elevator more reliable, perfect.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the elevator cabin flat level described in the utility model constructional drawing of holdout device under off working state that fall;
fig. 2 is the elevator cabin flat level described in the utility model constructional drawing of holdout device under in working order that fall;

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 elevator cabin flat level that the utility model the discloses 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 utility model, 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 utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications of doing according to the Spirit Essence of the utility model main technical schemes, within all should being encompassed in protection domain of the present utility model.
Claims (3)
