Embodiment Construction

[0022] Such as figure 1 As shown, the anti-fall protection device of the vertical elevator includes: a fixed rack 2 and a brake box 3, and the fixed rack 2 is fixed on the side of the car 1.

[0023] Such as figure 2 As shown, the brake box includes: a moving slider 31, a base plate 32, a support plate 33, a base plate guide rail 34, a support plate guide rail 35, a spring 36, a spring 37, and an electromagnet 38; the support plate 33 can move forward and backward along the base plate guide rail 34 , a spring 36 is placed between the support plate 33 and the base plate 32; the mobile slider 31 can move left and right along the support plate guide rail 35; 37.

[0024] Such as image 3 As shown, when the elevator is running normally, the teeth of the moving slider 31 are staggered with the teeth of the fixed rack 2.

[0025] Such as Figure 4 As shown, when the fall protection is activated, the teeth of the moving slider 31 mesh with the teeth of the fixed rack 2 to inter...

Abstract

The invention relates to the field of elevator equipment manufacturing technology, and particularly relates to a vertical-lifting elevator anti-falling protection device. The reasons of elevator falling mainly lie in the drop or breakage of a steel wire rope, overload operation, speed measurement and limiting device and equipment failure, and the elevator falling rarely happens. In order to overcome the shortcomings of the prior art, the invention provides a vertical-lifting elevator anti-falling protection device independent from the existing safety guarantee system. The device provided by the invention consists of a brake box embedded into a shaft wall and a fixing rack fixed on the side surface of a car. When an elevator falls, a brake instruction is given manually or by a speed sensor, an electromagnet in the brake box adsorbs a movable slider so that the teeth of the movable slider are meshed with the teeth of the fixing rack, the teeth of the fixing rack collide with the teeth of the movable slider repeatedly, and the impact force of the falling car is absorbed by a spring set; and when the kinetic energy is completely absorbed and the speed approaches to zero, the resistance against the brake box is greater than the total gravity of the car, thus a soft landing process of the car is formed to realize the brake of the car.

Description

technical field [0001] The invention relates to the technical field of elevator equipment manufacturing, and relates to an anti-fall protection device for a vertical lift elevator. technical background [0002] With the increase of high-rise buildings, the use of elevators increases thereupon. In order to ensure the safety of elevator operation, an elevator anti-fall protection device must be assembled. Nowadays, elevator fall prevention is mainly realized by devices such as speed governor, safety gear and buffer spring at the bottom of the hoistway. When the running speed of the elevator reaches or exceeds the set limit value, the speed limiter stops running, and lifts the connecting rod mechanism installed on the car beam with the help of the friction force in the sheave or the rope clamping mechanism, and through mechanical action Send a signal, cut off the control circuit, and force the safety gear to act at the same time, so that the car is forced to stop on the guide ...
