[0003] The existing anti-falling method often uses a speed limiter with a wire rope connected to a safety clamp to limit the speed of the stalled elevator, thereby achieving the anti-falling function;

At this time, when it is necessary to control the operation of the elevator, the controller in the elevator is adjusted, and these signals are transferred to the single-chip microcomputer 9. The single-chip microcomputer 9 controls the operation of the traction machine 11, and the traction machine 11 drives the traction rope 12 to extend and retract, thereby pulling the car 4 to change its height. In this process, the counterweight 10 will also change its height in the opposite direction as the car 4 changes its height. The speed sensor 8 is running, and the speed information of the car 4 that is changing its height is returned to the single-chip microcomputer 9 in real time;

[0027] The working principle of a safety elevator for preventing falling provided by the utility model is as follows: the top mounting plate 1 is installed on the designated position, and then the front side slide rail 2 is installed on the designated position. At this time, when it is necessary to control the operation of the elevator, the controller in the elevator is adjusted, and these signals are transferred to the single chip computer 9. The single chip computer 9 controls the operation of the traction machine 11, and the traction machine 11 drives the traction rope 12 to extend and retract, thereby pulling the car 4 to change the height. In this process, the counterweight 10 will also change the height of the car 4 while the height changes. At the same time, the pulley 53 slides on the front side slide rail 2, and at the same time, the speed measurement The sensor 8 operates and returns the speed information of the car 4 undergoing height change to the single-chip microcomputer 9 in real time. When the speed exceeds the specified speed, the single-chip microcomputer 9 controls the external oil pump, and the two brake pumps 76 operate at the same time.

When the upper side swivel seat 77 changes in height, it drives the two lower side connecting rods 73 and the two upper side connecting rods 75 to rotate, thereby driving the two connecting shafts 74 to be relatively close, and then driving the two clamps 78 to hold the front side slide rail 2, generating friction with the front side slide rail 2, achieving braking, and effectively preventing the car 4 from stalling and falling.
