Manual emergency braking device for lifting elevator

Abstract

The invention discloses a manual emergency braking device for a lifting elevator. The manual emergency braking device for the lifting elevator aims to solve the problem that in the prior art, due to the fact that the travel of an emergency braking and stopping executing mechanism is too long, emergent sticking and stopping of the elevator are delayed, and then safety risk of the elevator is increased. The manual emergency braking device for the lifting elevator comprises a pair of guide rails, an elevator car, a control device which is arranged at the inner top of the elevator car, a speed monitoring device which is arranged on the elevator car, is connected with the control device and is used for monitoring the lifting speed of the elevator car in an elevator shaft in real time and transmitting a monitored speed signal to the control device in real time, and an emergency braking and stopping executing mechanism which is arranged on the elevator car, is connected with the control device and is used for receiving an emergency braking and stopping signal transmitted by the control device and then executing an emergency braking and stopping action. According to the manual emergency braking device for the lifting elevator, the emergency braking and stopping executing mechanism comprises a servo motor and a safety gear connected with the servo motor, no force transmission mechanismis arranged intermediately, the travel is extremely short, the elevator car can be rapidly stuck and stopped on the guide rails after a microprocessor sends out an emergency braking and stopping command, and the safety risk of the elevator can be effectively reduced.

Description

technical field [0001] The invention relates to a manual emergency braking device for an elevator. Background technique [0002] With the increasing number of high-rise buildings in our country, elevators have become an essential tool for carrying people in buildings, and the safety of their operation is the focus of people's attention in the process of using elevators. The safety of its operation is the focus of people's attention in the process of using the elevator. However, in recent years, incidents of "cannibalism" and "injury" of elevators have occurred frequently, and the safety of elevators has attracted great attention for a while. [0003] For this reason, a variety of mechanical and electrical safety devices are equipped in the design and production of the elevator system to prevent dangerous accidents that may occur in the elevator. The prior art generally uses a centrifugal speed governor to limit the overspeed operation of the elevator. The following problem...
