Testing table, testing system and testing method for brake load moment of brake

Abstract

The invention discloses a testing table, a testing system and a testing method for brake load moment of a brake. The testing table for the brake load moment of the brake comprises a brake wheel, a pawl, a driving wheel, a first driving device, a second driving device and a rack, wherein the driving wheel and the brake wheel are both arranged on the rack, the first driving device is used for driving the driving wheel, the brake wheel is fixedly connected with the driving wheel, the brake wheel is provided with the pawl, the pawl is matched with ratchets, the second driving device is used for driving the ratchets, and one end of the pawl butts against the ratchets when braking is conducted. By means of the device, on-site braking tests do not need to be carried out on an escalator, corresponding testing data can be obtained by simulating the actual running process of the escalator on the device, on-site mounting and debugging work is reduced, debugging efficiency is improved, and potential safety hazards brought by the field tests are completely eradicated. The testing system and the testing method enable the testing process to be more convenient and enable the testing data to be more accurate.

Description

technical field [0001] The invention relates to the technical field of brake load moment testing of escalators or inclined moving walks, in particular to a brake load moment test bench, a test system and a test method thereof. Background technique [0002] According to relevant regulations, at least one or more brakes should be installed on escalators and moving walks. The main function of the brakes is to prevent the escalator or moving walk from being damaged by a sudden power failure or sudden abnormality. Brake to ensure the safe use of escalators or moving walks. After the brake is installed, it needs to be debugged to make the braking torque of the brake meet the corresponding requirements. When debugging the brake torque, a certain load of weight should be loaded To the escalator or moving walk, there are the following disadvantages in this way: [0003] 1. On-site testing is very labor-intensive and requires repeated handling of heavy weights; [0004] 2. The on-si...

Problems solved by technology

[0003] 1. On-site testing is very labor-intensive and requires repeated handling of heavy weights;

[0004] 2. The on-site test and adjustment are difficult, and there are many uncertain factors on site, so it is difficult to grasp the accuracy during adjustment;

[0005] 3. There is a danger of the weight hitting the bottom. When the braking force of the brake is not enough to stop the escalator, the weight will directly rush to the bottom of the escalator, causing damage to the escalator
