How to connect the lines of Hengda Fuji Elevator?

"Microcomputer-controlled safe and fail-safe escalator" is a new type of escalator innovatively designed by the technology research and development center of Hengda Fuji Elevator Co., Ltd. on the basis of full market research. The escalator fully applies computer network technology, and strictly demonstrates various technical parameters in the design and manufacture process. Redesign the non-running reverse monitoring device, intelligent fault monitoring device, intelligent step speed monitoring device, driving chain tensioning device, step collapse protection device, new escalator entrance and exit structure, turbine lubrication device, escalator chain and sprocket heat treatment technology, etc. According to the principle of innovation and continuous development, the new escalator Evergrande Fuji innovatively applied the following new technologies and processes: ①. It adopts a highly sensitive modular structure, and the escalator control system with Fuji CPM 1A-20CDR-A-V 1 microcomputer as the core has the characteristics of pace monitoring, intelligent operation, safety and reliability. Using Swedish Simon frequency converter, the HDFUJI program is compiled by ourselves, which makes the escalator have high sensitivity and intelligent photoelectric monitoring system. ②: Step-by-step quenching process of heat treatment mesh belt furnace is adopted for the step chain, and at the same time, the protective atmosphere of methanol cracking is used, so that the tensile strength of the step chain reaches above 250KN, which ensures the good toughness and strength of the step chain and further improves the safety and reliability of the escalator. The sprocket adopts three-stage nitriding process, which greatly improves the strength, toughness and wear resistance of sprocket. ③ The U-shaped cross fit design is adopted between the comb plate and the pedal, which improves the meshing depth of the comb plate and the pedal and improves the safety and reliability. At the same time, the automatic arc extinguishing device can effectively filter out interference and absorb impurities, avoid arc discharge of electronic circuits, and has good protection and anti-interference ability, thus ensuring the safety and reliability of the escalator electrical system. (4) Design a monitoring device for the non-running reversal of the escalator, and monitor the traction machine and chain at the same time to improve the reliability of safety monitoring. Comprises a PLC controller, a main speed measuring sensor arranged at one side of a chain wheel of a traction machine and an auxiliary speed measuring sensor arranged at one side of a chain stressed or an auxiliary chain wheel, and the auxiliary speed measuring sensor is connected with the PLC controller. Monitor the non-running reverse rotation of traction machine and chain respectively. No matter whether the traction machine or the chain is reversed, the escalator can stop running to prevent accidents and improve the reliability of safety monitoring. ⑤: Design a tensioning device for the transmission chain of the escalator to solve the problem that the escalator runs unsteadily due to the swing of the transmission chain when the traction machine is installed under the driving device, and at the same time shorten the horizontal length of the escalator. A tensioning sprocket is arranged on the tensioning box, and the tensioning sprocket pushes against the driving chain. Because of its adjustable tension, the problem that the escalator runs unsteadily due to the swing of the transmission chain is effectively solved without increasing the horizontal length of the escalator. ⑥: Design the escalator step collapse protection device, including the installation plate at one side of the comb plate and the lever below the step plate, which is greatly beneficial to the escalator's function of preventing step collapse and can be automatically reset after troubleshooting. ⑦: Design a new escalator entrance and exit structure, which has good overall effect, smooth and beautiful surface, no splicing interface and is not easy to scratch people. The escalator runs reliably, and the handrail belt will stop automatically when the entrance and exit are stuck by foreign objects, which can prevent accidents. ⑧ Design escalator lubrication device, including turbine oiler; The turbine oiler is connected with the oil nozzles installed at each oil injection point through oil pipes, which can conveniently lubricate the gearbox, bearing, chain and sprocket of the reducer. Because the pressure element of the turbine oiler is pressurized by the turbine, the friction when the turbine rotates is extremely small, it is not easy to be damaged, the service life is long, it does not need to be replaced frequently, the maintenance cost can be reduced, and the work is more reliable. The project was appraised as the outstanding scientific and technological achievement in Zhejiang Province by the appraisal of the achievements of the Science and Technology Department of Zhejiang Province, and there were five utility model authorizations related to the new microcomputer-controlled safe trouble-free escalator. They are: escalator non-running reverse monitoring device (patent number ZL200920309692.2), escalator lubricating device (patent number ZL20092030973 1.9), escalator entrance structure (patent number ZL20082 030385 1.3) and escalator driving chain tensioner. In addition, the automatic assistant also accepted two national invention patents: the gradual heat treatment method of escalator chain plate (acceptance number 2009 10309202.3) and the strengthening treatment method of escalator sprocket (acceptance number 2009 10309200.4).
