An elevator emergency braking device and braking method

Abstract

The invention discloses an emergency braking device for an elevator. The device comprises an elevator car, a traction steel rope is fixedly connected to the top of the elevator car, the part, on the two sides of the traction steel rope, of the top of the elevator car are fixedly connected with heightening blocks, sensing devices are arranged above the heightening blocks, the two sides of the elevator car are provided with braking positioning devices, and the braking positioning devices are installed in elevator shafts; and each sensing device comprises a first round pipe, the bottom of each first round pipe is fixedly connected to one corresponding heightening block, round rods are inserted into the first round pipes, one end of each round rod extends to one side of the traction steel rope, the end, close to the traction steel rope, of each round rod is movably connected with a rolling wheel, each rolling wheel is tangent to the traction steel rope, and a baffle sleeves the rod wall ofthe end, close to the traction steel rope, of each round rod. According to the emergency braking device for the elevator, the falling potential energy of the elevator car is buffered through a top end buffering device and a bottom buffering device, and the elevator car is stopped finally, and casualties caused by immediate falling of the car are avoided.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator emergency braking device and a braking method. Background technique [0002] With the gradual improvement of people's living standards, elevators have become a tool that is often used in people's lives. Since the motor is mechanical, unexpected accidents may occur during use, such as stalling, etc., so emergency braking devices are needed. To protect the safety of personnel and prevent the elevator from falling, most of the braking devices currently on the market are braked by installing a safety gear at the bottom of the elevator car. Although the brake can be used, the braking effect is not good. For this reason, we An elevator emergency braking device and braking method are proposed to solve the above-mentioned problems. Contents of the invention [0003] The object of the present invention is to provide an elevator emergency braking device and braking method ...
