Step and skirt panel safety gap measurement and hidden danger positioning system and method for escalator

Abstract

The invention discloses a step and skirt panel safety gap measurement and hidden danger positioning system and method for an escalator. The working efficiency of detection personnel is improved, and the labor intensity is reduced; the precision is high, detection errors caused by manual observation and poor personnel responsibility are eliminated, the detection personnel can be assisted in discovering hidden dangers more comprehensively, and escalator safety accidents caused by the hidden dangers are reduced to the utmost extent; and the precise hidden danger positioning function can help maintenance personnel to quickly conduct maintenance and adjustment. The step and skirt panel safety gap measurement and hidden danger positioning system and method for the escalator have significance on safety running of the escalator and personnel safety of passengers, and have a positive promoting effect on development of the whole quality supervision cause.

Description

technical field [0001] The invention relates to the field of escalators or moving walks, in particular to a system and method for measuring the safety gap between steps and aprons of escalators and locating hidden dangers. Background technique [0002] When the escalator is running, if the gap between the steps and the apron panels on both sides is too large, foreign objects or children's hands and toes will be involved, which will cause equipment damage or casualties. In recent years, children's fingers, toes or rubber shoes have frequently been involved in the gap between the sports steps and the apron board, causing personal injury. The testing agency of the quality supervision department needs to test the gap between the steps and the apron board when conducting supervisory inspection and regular inspection of the escalator. According to the national standard requirements: one side is not greater than 4mm, and the sum of both sides is not greater than 7mm. [0003] Howe...

Problems solved by technology

[0003] However, at present, the detection method for the gap between the step and the apron board at home and abroad is often manually measured with a feeler gauge or a steel ruler when the escalator stops running. There is no professional testing instrument and equipment. The main problems are as follows: First, when the step stops running There are differences between the test results when the escalator is running and the test results when the steps are moving (due to the wear of the guide rails and pulleys, the steps shake from side to side when the escalator is running); the second is that the use of steel rulers (feeler gauges) for manual measurement is inefficient and difficult to measure all gaps Carry out all measurements one by one, so it is easy to miss some hidden dangers; third, the resolution of steel ruler and feeler gauge is low, and the error of personnel reading is large, especially when the data is close to the critical value, it is easy to affect the judgment conclusion
