The elevator in use should be regularly inspected and maintained to ensure the safe operation of the elevator and extend the service life. Usually there are certain requirements in the regular cycle maintenance inspection cycle of the elevator. It is roughly divided into six methods: daily inspection, monthly inspection, quarter inspection, annual inspection and special inspection. It has a planned, purposeful and organized periodic circulation maintenance. an examination. Each type of maintenance inspection system has its own key points and specific contents in terms of methods; in the front and rear links, it is closely linked and closely related, and maintenance personnel should also formulate according to the frequency of use of elevators in this unit. The specific maintenance method of the elevator, and then carefully and rhythmically implement the established maintenance system. What are the differences between the various maintenance systems, what are the key parts of maintenance, and what are the specific features of the maintenance parts, as follows:

1 Daily inspection and maintenance system Daily inspection and maintenance system: Require maintenance personnel, daily use and operation of the elevator, ask the elevator driver if there is any problem, then personally inspect it, and finally make a check on each part of the inspection. Good day record. The key part of maintenance: should be placed in the correct operation of the elevator, placed on the stability of the elevator running speed. If problems are found, solve them in time to ensure that the elevators operate safely without failure. The specific parts of the daily inspection work are as follows:

1.1 Check the following items in terms of the correct operation of the elevator

(1) Whether the switches, buttons and signal indications on the control panel of the car are correct;

(2) The call of the outer station of the hall and the display of the floor are correct;

(3) Whether the plane position of the car stop layer is accurate;

(4) The control panel accepts the command and controls whether the actual running action is coordinated;

(5) Whether the actual load in the car and the rated load in the car are the same.

1.2 The following checks should be made regarding the stability of the elevator running speed.

(1) The speed of the automatic door machine during the whole process of opening and closing the door should be normal and stable;

(2) The speed of express and slow speed of the traction machine should be normal and stable;

(3) The speed of the express and slow cars of the traction motor should be normal and stable;

(4) The speed of the rotating wheel and the car of the speed limiter device shall be the same;

(5) When the elevator is running at full speed, when it is quickly converted to slow speed, the car should have a safe, stable and comfortable feeling when starting and stopping.

(6) The elevator short-range operation of the elevator should be stable and normal. These are the focus and specific parts of the daily maintenance inspection system.

2 Weekly inspection and maintenance The focus of the weekly maintenance system: Maintenance personnel are required to check the reliability of the elevator safety device and the flexibility of the elevator running parts every week to ensure the safe operation and normal operation of the elevator. The details of the weekly inspection and maintenance system are as follows:

2.1 Elevator operation safety device reliability check

(1) Whether the door lock function is reliable;

(2) Whether the electrical limit interlocking function of the car and the hall door is reliable;

(3) Whether the emergency stop button or safety switch in the car is reliable;

(4) Whether the safety clamp limit switch is reliable;

(5) Whether the safety window switch function is correct;

(6) Whether the car top control box and the steering switch function correctly and reliably.
