Problems solved by technology

The disadvantage is that the braking distance usually detected by the elevator industry is the elevator car travel during the period from the moment of "cutting off the power supply of the drive host" to the stop of the elevator car. In addition, this technical solution only measures and displays the braking distance, and the braking distance cannot be judged directly from the detection data, because the braking distance must be judged according to the running speed parameters. The allowable braking distance of the speed elevator is different

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0016] Such as figure 1 As shown, the elevator braking parameter detector of the present invention includes an instrument casing 1, an acceleration sensor 2, a data processor 4, a display 5, a power supply battery 7, a Micro-USB socket 6, an SD card slot and an SD card 3 and seven modules constitute. According to the relevant standards of elevators, the braking test of the elevator is divided into three types: 125% rated load downward braking test, rated load downward braking test and no-load upward braking test. The detection operation must be determined according to the requirements of the detection working conditions Elevator load and running direction, put the instrument in the elevator car, control the elevator to run at the rated speed, then cut off the power supply of the drive host, make the brake brake → the elevator decelerates → stop running. Dur...

Abstract

An elevator braking parameter detector is formed by seven modules of an instrument housing, an acceleration sensor, a data processor, an SD card slot and SD card, a displayer, a power supply battery, a Micro-USB charging jack. Elevator cage motion information in the elevator braking process is collected by the acceleration sensor; and a speed-time curve graph and elevator braking parameters of elevator braking distance, elevator braking deceleration speed and elevator braking time and the like in the elevator braking process are obtained through analysis and calculation of the data processor, and the detection results are displayed and output through the displayer. The instrument is exquisite in structure and simple to detect and operate; setting of detection items and measurement data accords with elevator standard and industry habits; and through the arrangement of the SD card and the charging jack, compatibility is good.

Description

technical field [0001] The invention relates to a detection instrument, more specifically, a special detection instrument for testing the technical parameters of braking capacity of elevator brakes. Background technique [0002] The brake of the elevator is equivalent to the brake system of the car. In view of the characteristics of the elevator running in space, the brake of the elevator is more important than the brake system of the car. It is one of the most important components to ensure the safety of the elevator. [0003] The function of the elevator brake should be reflected by the braking ability, usually by detecting the operating parameters of the elevator car during the elevator braking process to evaluate the braking ability technical index of the brake. At present, the testing instrument used to test the braking parameters of the elevator in the elevator industry is the elevator transportation quality analyzer. The car can detect and display the speed and accel...
