(2) Weekly inspection and maintenance system. Suitable for elevator equipment use frequency is very high, as well as key, key user units elevator maintenance work. Of course, the weekly inspection and maintenance work content is also suitable for maintenance supervisors to carry out daily maintenance quality sampling work inspection content. ① weekly inspection and maintenance work should be focused on the inspection and maintenance of elevator safety devices, as well as the flexibility of the elevator running parts. ② in the safety and reliability of the elevator operation safety devices, mainly need to check and maintain the elevator door locks, electrical interlocking contacts and safety circuit of the safety switch is reliable, as well as the brake performance and car door safety protection devices. ③ on the flexibility of the elevator running parts, mainly need to check and maintain the flexibility of the car floor door pulley slider and door machine moving parts, as well as the motor, worm gear, guide wheel and other rotating clean lubrication condition.
(3) monthly inspection and maintenance system. Apply to most of the running condition of good elevator routine maintenance work. Of course, the monthly inspection and maintenance work can also be used as maintenance supervisors and full-time quality inspectors on the maintenance of the quality of work to carry out spot checks, inspection of the inspection content. ① monthly inspection and maintenance work is focused on checking the elevator due to frequent operation and may be easy to loose, easy to wear parts (such as car door) of the firmness and integrity, so that the elevator in the overall structure, in a complete and undamaged, firm, safe and reliable good working condition. ② in the elevator fastening parts of the firmness of the content to be checked and maintained is mainly car floor door bolts, floor door since the resumption of the door device, guide bracket pressure plate bolts, traction rope rope head, balance compensation device, the control cabinet of the electrical fastening screws, shaft information devices. ③ For the integrity and reliability of the parts that are easy to wear out due to sliding and rolling, the contents to be inspected and maintained or replaced are mainly the car floor door pulley slider, door drive belt, boot lining of the guide shoe, each fuse core traction, traction wire rope and so on. ④ Of course, the elevator is not carried out daily and weekly inspection and maintenance work, in the monthly maintenance, must be the corresponding daily and weekly inspection and maintenance work required content (maintenance, inspection projects) into the scope of the monthly maintenance work, and the elevator to carry out a more comprehensive cleaning and regular inspection and maintenance of the maintenance work.
(4) quarterly inspection and maintenance system. Apply to running in good condition, the use of less frequent maintenance of the user elevator, as well as the implementation of normal monthly maintenance work is not carried out or easy to neglect, omit the maintenance of the project. Similarly, the content of quarterly inspection and maintenance work can also be used as the inspection content for maintenance supervisors and full-time quality inspectors when they carry out random inspection of maintenance work quality. ① quarterly inspection and maintenance work focus should be placed on the impact of the elevator's reliability of the components of the gap or relative size of the inspection, adjustment and maintenance, and take into account the daily, weekly, monthly inspection of negligence, omission. ② quarterly maintenance, the elevator between the moving parts of the clearance or relative size of the inspection, adjustment of the main content of the inspection and adjustment of the automatic door system, the door knife and the floor of the hall door spacing, the car floor door electrical interlocking contacts reliable engagement, as well as the traction wire rope between the rope tightness, brake clearance, car counterweight device of the distance between the plate and the top surface of the buffer, the safety of embedded wedges and guide rails Both sides of the gap and leveling accuracy, etc.
(5) annual inspection and maintenance system. Apply to the elevator in government departments before the annual inspection routine inspection and maintenance. Of course, the annual inspection and maintenance work content can also be used as a full-time quality inspection personnel in the annual inspection of the annual maintenance work quality inspection must be checked. ① annual inspection and maintenance work focuses on the safety and reliability of the elevator, easy to wear parts and components of the various systems important related to size, a comprehensive, systematic inspection, maintenance work. ② need annual inspection and maintenance of the elevator, must check and maintain the parts and the main content: elevator performance and safety and reliability of the inspection, testing, wear parts and their integrity and reliability of the replacement of the elevator affecting the reliability of the work of the moving parts of the elevator between the important gap or relative size of the inspection, adjustment and so on.
(6) Special inspection and maintenance system. Apply to the elevator for a longer period of time and / or more problems and failures, generally special inspection and maintenance cycle for 3 to 5 years, of course, according to the specific use of elevators, maintenance conditions and changes < or advance or delay >. Similarly, the special inspection and maintenance work content can be used as the mandatory content of the quality inspection when the full-time quality inspection personnel carry out the special maintenance work quality inspection. ① elevator special inspection and maintenance work is what we usually say that the project repair or overhaul, the need for maintenance personnel according to the specific conditions of the elevator to determine the content of special inspection and maintenance. However, the safety items involved (such as speed limiter safety clamps, safety circuit switches, door protection system, etc.) must be taken as the mandatory items of special inspection and maintenance. ② Although the specific conditions of the elevator is different, the elevator's special inspection and maintenance that the project repair or overhaul work will be different, but the common special repair project content: traction brakes, a variety of rope wheels, guide rails, traction ropes, car doors, compensation devices, shaft information devices, control cabinets in the inspection and maintenance of the electrical components or replacement.
