Embodiment Construction
[0073] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0074] The elevator 10 with emergency braking system in the present invention, such as figure 1 As shown, it includes a car 1, a control unit 110, a speed sensor 101 and / or an acceleration sensor 102, and an emergency braking device 3. A T-shaped guide rail 2 is fixedly arranged in the running channel 20 of the car 1, and the car 1 is movable. It is installed in the guide rail 2 and can run up and down along the guide rail 2. The upper and lower parts of the car 1 are provided with guides 1a and 1b, respectively.
[0075] like Figure 2a As shown, the emergency braking device 3 includes a braking assembly 30, an emergency braking device frame 32, an upper stopper 32a and a lower stopper 32b, and the emergency braking device 3 is installed on the mobile device through the emergency braking device frame 32. The moving device can be a...

The invention discloses an emergency braking device which comprises an actuator, a first combination, a second combination and at least one braking piece, wherein the actuator is mounted at one ends of the two combinations; the braking pieces are located at the other ends of the two combinations; after the actuator is triggered, the actuator is changed to an opened position from a closed position;the emergency braking device is changed to a triggered state from a normal operation state; the braking pieces are contacted with guide rails to generate friction; the emergency braking device is changed to a braking state from the triggered state under the action of the friction; the actuator is changed to the closed position from the opened position; and the emergency braking device brakes a moving device. The emergency braking device is simple in structure and operates under the control of a control unit to achieve braking in two directions; only one actuator can achieve triggering and reset of safety tongs; at the same time, a hazardous condition of out-of-control operation of a car occurring in an acceleration or speed reduction process of an elevator is avoided with the adoption ofa speed triggering mode and an acceleration triggering mode; and the response is quicker and more effective.
Description
technical field [0001] The invention relates to the field of elevators, in particular to an elevator emergency braking system. Background technique [0002] During the operation of the elevator, there may be an accident that the elevator car falls or goes down over the speed. At this time, safety gear is usually used to deal with it, while the traditional safety gear is generally triggered by the speed limiter. Because the speed governor-tensioner system has problems such as complex structure, large space occupation of the machine room, and easy noise generation, a large number of technical solutions for braking devices with electromagnetic actuators have appeared in recent years. Self-triggering is realized under signal control, thereby canceling the governor-tensioner system. [0003] For this kind of braking device using electromagnetic actuator, generally, when the elevator is running normally, the electromagnetic force of the electromagnetic actuator is balanced with t...
