buffer elevator

Abstract

The invention relates to a buffer elevator. The buffer elevator comprises an elevator lift car arranged in an elevator shaft, a vibration conversion device and a power storage device connected with the vibration conversion device are arranged on the car wall of the elevator lift car, a damping device is arranged on a base plate of the lift car, the vibration conversion device is used for converting kinetic energy in the damping device into electric energy, and buffer devices are arranged on the outer side of the top of the lift car and the outer side of the bottom of the lift car respectively and are powered by the power storage device. Two transverse latches are arranged outside the lift car of the error-opening-prevention elevator, when the elevator is overhauled, the triangular prism end of a rotating shaft is sleeved with a triangular key by a maintenance worker inside the lift car, the rotating shaft is forwards rotated to drive the transverse latches through gears to advance in the direction of the lateral wall of the shaft, and rotation is ended when the ends of the transverse latches are completely inserted into locking grooves. When the transverse latches are inserted into the locking grooves, even though being suddenly started, the elevator cannot ascend or descend, and the personnel safety of the maintenance worker is guaranteed.

Description

technical field [0001] The invention relates to an elevator, in particular to a buffer elevator. Background technique [0002] When the elevator car is moving up and down at high speed, the irregular airflow will aggravate the vibration of the elevator, and the elevator itself will also vibrate. The vibration of the elevator, the natural frequency of the elevator will change as the frequency of the objects in the elevator changes. [0003] In addition, when the elevator stops and starts, it will get energy due to the state of motion. However, if this part of energy is not eliminated, the internal occupants will feel vibration and feel overweight or weightless, which will not only make the internal occupants feel uncomfortable, but also waste Tired part of the energy. [0004] The energy consumption of elevators has always been a problem that needs to be paid attention to during the operation of elevators. The energy consumption of elevators in buildings is often very large...

[0003] In addition, when the elevator stops and starts, it will get energy due to the state of motion. However, if this part of energy is not eliminated, the internal occupants will feel vibration and feel overweight or weightless, which will not only make the internal occupants feel uncomfortable, but also waste part of the energy

[0004] The energy consumption of elevators has always been a problem that needs to be paid attention to during the operation of elevators. The energy consumption of elevators in buildings is often very large, but few people pay attention to it. According to the survey data released by Germany, the annual electricity consumption of elevators in 27 EU countries is as high as 1.8 billion kwh, and the reasonable application of energy-saving measures can reduce the power consumption of elevators by half.
