Beneficial effect of the present invention is: a kind of device that prevents accidental movement of elevator cage of the present invention, but it comprises the micro-switch sway and touch the slide bar of the described micro-switch that automatically resets of automatically reseting of motor, quadric linkage, connection elevator safety loop, and the lockplate that is fixedly connected on car guide rail; Described lockplate offers lock hole, and when moving right, the right-hand member of slide bar can insert described lock hole when described slide bar; When left past movement of described slide bar, the right-hand member of slide bar can break away from described lock hole; Adopt the device of said structure, when Elevator landing, elevator main control board is controlled the motor rotation, move right by quadric linkage band moving slide-bar, slide bar moves right in process, automatically reset micro-switch action of shake-up, thus elevator safety loop cut off, realize the electric security protector purpose of elevator; Simultaneously, the right-hand member of slide bar inserts described lock hole, thereby makes elevator locked, avoids car to move, and realizes the mechanical type safety method.Therefore, the present invention can effectively stop passenger's potential safety hazard that accidental movement of elevator cage brings when entering and exiting elevator.
Description of drawings
Fig. 1 is structural representation of the present invention.
Structural representation when Fig. 2 slide bar of the present invention goes out of lock the hole.
Structural representation when Fig. 3 is slide bar insertion lock hole of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of device that prevents accidental movement of elevator cage of the present invention, its structure is, it comprises the motor 2 that is arranged on sedan-chair top board 1, but also comprise quadric linkage 3, connect micro-switch 5 sway and touch the slide bar 4 of the described micro-switch 5 that automatically resets of automatically reseting of elevator safety loop, and the lockplate 8 that is fixedly connected on car guide rail 7; The output shaft of described motor 2 connects the left end of described quadric linkage 3, and the right-hand member of quadric linkage 3 connects the left end of slide bar 4, and the micro-switch 5 that automatically resets is positioned at slide bar 4 tops; Described lockplate 8 offers lock hole 80, and when past the moving right of described slide bar 4, the right-hand member of slide bar 4 can insert described lock hole 80; When past the moving left of described slide bar 4, the right-hand member of slide bar 4 can break away from described lock hole 80.Wherein, lockplate 8 is installed on often the corresponding position of door layer by layer.Further, described quadric linkage 3 comprises long connecting rod 31 and short connecting rod 30, the output shaft of described motor 2 is articulated in the left end of described short connecting rod 30, the left end of the right-hand member of short connecting rod 30 and long connecting rod 31 is hinged, the right-hand member of long connecting rod 31 is articulated in the left end of described slide bar 4, this quadric linkage 3 is simple in structure, reliable operation.
As preferred embodiment, described slide bar 4 is provided with contact boss 40, and the described micro-switch 5 that automatically resets is provided with pulley 50, and it is simple and reliable for structure.When moving right, contact boss 40 touches pulley 50, thereby touches the micro-switch 5 that automatically resets, and then cuts off elevator safety loop when slide bar 4; When moving left, contact boss 40 no longer touches pulley 50 when slide bar 4, and the micro-switch 5 that automatically resets just automatically resets, thereby connects elevator safety loop.
