Problems solved by technology

However, the buffer is generally installed at the bottom of the elevator or the bottom of the well. If the elevator accidentally falls, the occupants will panic. And with the increasing height of buildings today, the role of the buffer is becoming more and more limited.

Embodiment 1

[0022] A safety elevator such as figure 1 As shown, it includes a hoistway 1 and a car 2 arranged in the hoistway 1; a track 3 for guiding the operation of the car 2 is arranged in the hoistway 1, and a deceleration device is arranged in the hoistway 1; a deceleration device is arranged on the car 2 Cooperating coupling means and control means for controlling the connection and disconnection of the coupling means to the reduction gear.

[0023] The deceleration device is fixed on the hoistway 1 through the hydraulic cylinder 5, and several deceleration sliders 4 are evenly distributed from top to bottom and interlocked with each other. Hinged to the hook 6 on the outer wall of the car 2, the control device includes a speed detector for detecting the speed of the car 2 and controls the rotation of the hook 6 so that the hook 6 can be hooked on the deceleration slider 4 or disengaged from the deceleration slider 4 The rotating mechanism for switching between the two states. The...

Embodiment 2

[0027] The difference from Embodiment 1 is that the speed detector is an electronic speed detector, and the rotating mechanism is an electric motor.

Abstract

The invention discloses a safety elevator. The safety elevator comprises a shaft way and a lift car, wherein the lift car is arranged in the shaft way; the shaft way is internally provided with a track which is used for guiding the lift car to run and a speed reduction device; the lift car is provided with a connection device which is matched with the speed reduction device and a control device which is used for controlling the connection device to be connected with and disconnected from the speed reduction device. According to the safety elevator disclosed by the invention, when the situation that the speed of the lift car is too fast is detected by the safety elevator, the speed is reduced through hooking a hook to speed reduction sliding blocks, and the speed reduction effect is obvious; when the kinetic energy which is generated during the speed reduction of the lift car is converted into the hydraulic energy of a hydraulic cylinder, the speed is reduced by simultaneously driving a buffer piece and supporting pieces by the hydraulic cylinder, and the safety is further ensured.

Description

technical field [0001] The invention relates to a safety elevator and belongs to the field of elevator manufacturing. Background technique [0002] With the continuous improvement of building heights, the application of elevators is becoming more and more extensive, and the safety of elevators is becoming more and more important. Common elevator safety systems use buffers to cushion the elevator when it breaks down or squats in an accident, thereby alleviating the impact on the elevator or the occupants in the elevator. However, the buffer is generally installed at the bottom of the elevator or the bottom of the shaft. If the elevator accidentally falls, the occupants will panic. Moreover, as the height of buildings continues to increase today, the effect of the buffer is becoming more and more limited. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a safe and reliable device. [0004] The technical solu...
