The utility model beneficial effect is:
The described a kind of device that prevents the lift car accidental shifting of the utility model; But it comprises the micro-switch sway and touch the litter of the said 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; Said lockplate offers lock hole, when said litter when moving right, the right-hand member of litter can insert said lock hole; When past the moving in a said litter left side, the right-hand member of litter can break away from said lock hole; Adopt the device of said structure; When Elevator landing, the rotation of elevator master control board control motor drives litter through quadric linkage and moves right; Litter moves right in the 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 litter inserts said lock hole, thereby makes elevator be locked, and avoids car to move, and realizes the mechanical type safety method.Therefore, the utility model can effectively be stopped passenger's potential safety hazard that the lift car accidental shifting brings when entering and exiting elevator.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Structural representation when the litter of Fig. 2 the utility model goes out of lock the hole;
Fig. 3 is the structural representation of the litter of the utility model when inserting lock hole.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Extremely shown in Figure 3 like Fig. 1; The described a kind of device that prevents the lift car accidental shifting of the utility model; Its structure is; It comprises the motor 2 that is arranged on the sedan-chair top board 1, but also comprises quadric linkage 3, connect micro-switch 5 sway and touch the litter 4 of the said 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 said motor 2 connects the left end of said quadric linkage 3, and the right-hand member of quadric linkage 3 connects the left end of litter 4, and the micro-switch 5 that automatically resets is positioned at litter 4 tops; Said lockplate 8 offers lock hole 80, when said litter 4 when moving right, the right-hand member of litter 4 can insert said lock hole 80; When said litter 4 when moving left, the right-hand member of litter 4 can break away from said lock hole 80.Wherein, lockplate 8 is installed on whenever the corresponding position of door layer by layer.Further; Said quadric linkage 3 comprises long connecting rod 31 and short connecting rod 30; The output shaft of said motor 2 is articulated in the left end of said short connecting rod 30, and the left end of the right-hand member of short connecting rod 30 and long connecting rod 31 is hinged, and the right-hand member of long connecting rod 31 is articulated in the left end of said litter 4; This quadric linkage 3 is simple in structure, reliable operation.
