Background
With the high-speed development of Chinese economy, the living standard of people is continuously improved, and the elevator becomes a common transportation means for people to travel in daily life. While bringing great convenience to people's travel, safety accidents caused by elevators also occur sometimes. Some accidents are transmitted through news media, causing great panic to society. How to ensure the safety of the elevator, meets the beautiful living needs of people on safe trip, and becomes a problem of increasing attention of government departments.
According to the requirements of inspection rules and standards in China, a plurality of projects of the elevator are required for safety clearance values, wherein the safety clearance values are directly exposed in the process of taking the elevator by people, and two main categories are easily damaged by passengers.
One type is the gap between the door leaves of an elevator car door or landing door or between a door leaf and the surrounding static structure. According to the gauge requirements of traction type elevators and hydraulic elevators: when the elevator door is closed, gaps between the door leaves and gaps between the door leaves, the upright posts, the door lintel and the sill are not more than 6mm for the passenger elevator; for freight elevators not larger than 8mm, it is allowed to reach 10mm due to wear during use. According to the gauge requirement of the sundry elevator: after the door is closed, gaps between the door leaves and the upright posts, the door lintel and the sill are not more than 6mm; due to wear during use, it is allowed to reach 10mm.
Another type is the gap between the steps or pallets of the escalator and the travelator and the apron. According to the gauge requirements of the escalator and the moving pavement: the apron plates of the escalator and the moving sidewalk are arranged on two sides of the steps, the pedals or the adhesive tape, the horizontal clearance of any side is not more than 4mm, and the sum of the clearances at symmetrical positions of two sides is not more than 7mm. If the apron of the travelator is placed above the tread or the adhesive tape, the vertical clearance measured between the tread surface and the lower end of the apron should not exceed 4mm; when the pedal or the adhesive tape moves transversely, a gap is not allowed to be formed between the side edge of the pedal or the adhesive tape and the vertical projection of the apron board.
Both types of gaps are directly exposed in the process of taking the elevator by the passenger, particularly the gaps between the steps of the escalator and the moving walkway and the apron, and the passengers can be hurt in the whole taking process of the passenger. How to ensure that the values of the two types of gaps meet the requirements of the gauge has very important significance for preventing the occurrence of accidents of injuring passengers.
At present, the detection means of the inspection institutions at home and abroad for the two types of gaps are usually manual measurement by adopting a feeler gauge or a steel ruler, and no professional detection instrument and equipment exist yet.
