The invention relates to the technical field of lift buffer detecting devices, in particular to a lift buffer reset time detecting device. The lift buffer reset time detecting device comprises a grating ruler sensor, a supporting seat, an information processing module and a displayer. The supporting seat is arranged at the bottom of a pit of a lift car. The grating ruler sensor comprises a main ruler and a reading head, wherein the main ruler is connected with the top of the lift buffer, and the reading head is installed on the supporting seat. The reading head is electrically connected with the displayer through the information processing module. The lift buffer reset time detecting device can rapidly and accurately measure the reset time and reset speed of a lift buffer; and besides, when the recovery time of the lift buffer is measured, it is not needed to change the structure of the lift buffer, and the lift buffer reset time detecting device is not limited by the environment of the bottom of the pit of the lift car or limited by the type of the lift buffer and is simple in structure and convenient to install.
Description
technical field [0001] The invention relates to the technical field of elevator buffer detection equipment, in particular to an elevator buffer reset time detection device. Background technique [0002] The elevator buffer is an elevator safety device that provides the last safety protection for the elevator. It can buffer the elevator car when the elevator fails to protect the safety of passengers and equipment. [0003] In order to enable the elevator buffer to have a proper buffering effect, the reset time detection of the elevator buffer is generally performed. There are two types of existing elevator buffers: the first one, the human eye judges the state of the buffer, and uses a stopwatch to measure the time at the same time; this method of judging by human eyes is greatly affected by human factors and has low measurement accuracy. The second is to judge the state of the buffer through a pressure sensor, an ultrasonic range finder or a laser range finder, and use a mi...
