Said litter is provided with the contact boss, and the said micro-switch that automatically resets is provided with pulley.
Also be provided with guide pin bushing on the said sedan-chair top board, the said litter of said guide pin bushing socket.
It also comprises the pressure guide plate, and said lockplate is fixedly connected on car guide rail through pressing guide plate.
Said quadric linkage comprises long connecting rod and short connecting rod, and the output shaft of said motor is articulated in the left end of said short connecting rod, and the right-hand member of short connecting rod and the left end of long connecting rod are hinged, and the right-hand member of long connecting rod is articulated in the left end of said litter.
Beneficial effect of the present invention is:
A kind of device that prevents the lift car accidental shifting of the present invention; 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 present invention can effectively stop passenger's potential safety hazard that the lift car accidental shifting brings when entering and exiting elevator.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Structural representation when Fig. 2 litter of the present invention goes out of lock the hole;
Fig. 3 is a litter of the present invention structural representation when inserting lock hole.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
Extremely shown in Figure 3 like Fig. 1; A kind of device that prevents the lift car accidental shifting of the present invention; 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.
As preferred embodiment, said litter 4 is provided with contact boss 40, and the said micro-switch 5 that automatically resets is provided with pulley 50, and it is simple and reliable for structure.When litter 4 past 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 litter 4 past moving left, contact boss 40 no longer touches pulley 50, and the micro-switch 5 that automatically resets just automatically resets, thereby connects elevator safety loop.
