In addition, the accuracy of the car’s stay between floors is also one of the reasons for elevator accidents. People always ignore the accuracy of the elevator’s stay and take it for granted to step into the elevator. If the elevator’s stay has not reached the correct position, which is prone to accidents

Embodiment
[0027] In practical applications, when the elevator car 2 has not reached the designated floor position, the linear drive module 34 remains in a contracted state. Under the push of the elastic member 35, the positioning pin 32 slides closely against the guide rail 1. When the car 2 reaches At the designated floor position, the positioning pin 32 corresponds to the position of the locking hole 31. At this time, the linear drive module 34 enables the positioning pin to be inserted into the locking hole 31, and the car 2 is fixed at the floor position. The linear drive module 34 pulls the positioning pin 32 out of the locking hole 31, and now the car 2 is unlocked and can run freely.
[0028] When the car 2 falls out of control, the friction wheel 4 decelerates the car 2 during its descent. Since the positioning pin 32 is close to the guide rail 1 under the action of the elastic member 35, when the car 2 slides to the specified During the position of the floor, the positioning pi...

The invention relates to an elevator safety device which comprises guide rails and a cage, wherein the cage is capable of sliding and lifting on the guide rails; the elevator safety device is characterized in that locking devices are arranged between the guide rails and the cage; a plurality of locking holes are formed in the guide rails; the locking devices are corresponding to the locking holes; positioning pins on the locking devices are correspondingly buckled with the locking holes; the locking holes are uniformly distributed; the distance of the locking holes is corresponding to the distance of the floors. According to the elevator safety device, through the structure form of the positioning pins combined with the locking holes, the cage can be safely and firmly positioned on an appointed position; in a running process of the cage, under the effect of an elastic component, the positioning pin can be clung to and compressed on the surface of the guide rails all the time; when the cage falls in the running process, the positioning pins can be timely automatically inserted into the locking holes, so that the cage is stopped to fall off; the elevator safety device has a compact structure and has a position locking function and a falling buffering safe locking function.
Description
technical field [0001] The invention relates to an elevator component, in particular to an elevator safety device. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. The elevator car is a very important part of the elevator. The stability, rationality and safety of the elevator car operation are the key factors to determine the elevator grade. [0003] At present, the elevator car generally adopts a suspended car structure. This kind of elevator structure is relatively simple, but its safety performance depends on the strength of the cable. Accidents caused by fatigue. In addition, the accuracy of the car’s stay between floors is also one of the reasons for elevator accidents. People always ignore the accuracy of the elevator’s st...
