Description
Technical Field
The invention relates to an elevator, in particular to an elevator maintenance system.
Background
The safety of passengers and elevator equipment is mainly considered in the conventional elevator protection function, the safety of operators is less considered, and the existence and the behavior of the operators cannot be monitored.
During debugging and maintenance operation of the elevator, operators may appear in various areas such as a machine room, a car roof, a car, a pit, a floor gate and the like according to working requirements. Taking the car roof entering as an example, the standard operation steps are as follows:
1) if the machine room or the top layer door control equipment accessories are used, the maintenance device is operated to enable the elevator to enter a maintenance state, and the elevator does not respond to calling instructions of the landing and the car at the moment;
2) the elevator is maintained and operated, the lift car is moved to a proper position, and the height difference between the top of the lift car and the ground of a certain floor is small;
3) opening a landing door at the landing, and transmitting a landing door lock switch off signal to an elevator control system to further prevent the elevator from running;
4) an operator presses an emergency stop button on the car top at the landing door to further prevent the elevator from running;
5) an operator enters the car top, the landing door is closed, and a door lock closing signal of the landing door is transmitted to an elevator control system;
6) if the elevator needs to be operated by an operator, the maintenance switch is operated on the car roof to enter a maintenance mode, meanwhile, the emergency stop button is recovered, and the elevator is operated by pressing the designated uplink button and the designated downlink button.
The above operations realize basic protection and avoid abnormal movement of the elevator when the operator enters the car roof depending on the standard operation steps of the operator and the functions of the elevator system, but in the annual elevator casualty accident statistics, the casualty accidents of professionals caused by elevator debugging and maintenance work still account for a higher proportion. The main reasons are as follows:
1) the maintenance worker is not operated properly. Even if the process is standardized, the operation is not completely standardized due to various reasons, such as busy work, unskilled business, accidental negligence, neglect of part of steps after the operation process is interrupted due to unexpected reasons, and the like. For example, when the guide rail, the guide shoe and the oil cup are checked, the landing door is opened and directly enters the car roof, the emergency stop button is not pressed, an operator thinks that the door lock switch is disconnected when the landing door is opened, and the elevator cannot run; the operation of pit components and safety switches in the pit is checked, when a landing door is opened and the pit enters, an emergency stop button is not pressed, and the elevator can run after the landing door is closed, so that danger is generated; the operating personnel at the car top recovers the emergency stop button, but does not set the maintenance mode, and at the moment, the elevator can respond to the hall call to move, so that danger is generated.
2) Many people are in the time of the cooperation operation in different positions, and the cooperation is not good, fails to carry out effective communication during the operation elevator: for example, when a machine room person operates the elevator to excessively move upwards, the operator neglects the existence of the car roof, so that the car roof person is squeezed between the roof plate and the top of the car; the situation is similar when entering the pit.
CN108529368A and CN108529369A provide elevator maintenance support systems that can ensure the safety of elevator operators by monitoring the behavior and position of operators wearing wearable devices to limit the operation functions of elevators. However, such an elevator maintenance work support system is complicated, expensive, and poor in usability, and thus cannot be widely popularized.
