Description
Technical Field
The invention relates to the technical field of detection, in particular to detection equipment for an escalator and a moving sidewalk.
Background
With the rapid development of urbanization, large-scale integrated service centers such as businesses and the like are gradually increased, and the application of escalators and moving sidewalks is more and more extensive. The maintenance, inspection and detection of the escalator and the moving sidewalk are well done, the life and property safety of people is guaranteed, and the escalator and the moving sidewalk are the responsibility of elevator maintenance personnel and inspection and detection mechanisms.
The comb plate protection device is a device for protecting the comb plate in the escalator and the moving sidewalk and preventing the step from being damaged, when the comb plate and the step are clamped into a large and hard foreign matter, if the escalator or the moving sidewalk continuously runs, the foreign matter clamped between the pedal and the comb plate is extruded, so that the comb plate tilts, meanwhile, the comb plate and the step cannot be normally meshed, and the comb plate collides with the step, at the moment, if the comb plate protection device is not arranged, the continuous running of the escalator or the moving sidewalk can cause the damage to the comb plate and the step. According to the requirements of 6.2 comb plate protection in elevator supervision and inspection and regular inspection rules, escalator and moving sidewalk (TSGT 7005-2012): when foreign matters are clamped into the escalator or the moving sidewalk and the comb teeth cannot be normally meshed with the steps or the pedals, so that the comb plate collides with the steps or the pedals, the escalator or the moving sidewalk should automatically stop running. The comb plate protection switch is required to be subjected to simulation operation in daily maintenance, inspection and detection. However, through on-the-spot discovery, the instrument that the tester is used for triggering the comb plate protection switch action is all nonstandard, for example adopts tools such as spanner, flat mouthful screwdriver to remove to sled and move the comb plate, and these nonstandard instruments often injure hand or damage comb plate and step surface, still can not trigger the comb plate protection switch effectively simultaneously. Therefore, a safe and practical tool is needed to check the effectiveness of the comb plate protection switch. In addition, in the daily maintenance, inspection and detection process of the escalator and the moving sidewalk, the safety clearance between the components is also one of very important items, and has very important significance for the life safety of passengers and the normal use of the escalator and the moving sidewalk. According to the requirements of 5.1 comb teeth and comb plates in elevator supervision and inspection and regular inspection rules, namely escalator and moving sidewalk (TSGT 7005-2012): the meshing depth of comb teeth of the comb plate and tooth grooves of the tread surface is at least 4mm, and the gap is not more than 4 mm; 4.6 step, footboard or sticky tape and apron plate clearance requirement: the apron boards of the escalator or the moving sidewalk are arranged on two sides of the steps, the pedals or the adhesive tapes, the horizontal clearance on any side is not more than 4mm, and the sum of the clearances at symmetrical positions on two sides is not more than 7 mm; 4.1 requirements of the hand strap: the distance between the opening of the handrail belt and the guide rail or the handrail support is not more than 8mm under any condition; 4.4 requirements for the gap between dado panels: the gap between the dado panels should be no more than 4mm with rounded or chamfered edges. It follows that the position and the gap requirements are different. In the field measurement process, the tester needs to constantly go to a tool box to find different measuring tools so as to adapt to the measurement of different gaps, and the efficiency is very low.
