Description

Active safety elevator

Technical Field

The utility model belongs to the elevator field, concretely relates to initiative safety elevator.

Background

With the progress and development of society, elevators are increasingly used to provide travel services for the public in public places, particularly large urban population gathering and gathering areas. Thus, accidents caused by elevator faults are caused, and the elevator accidents are frequently heard, which causes serious loss to the life safety of people. With the promotion of the modernization process of our country, the use number of various elevators is continuously increased, so that the potential safety hazard is increased. Although the safety technical measures of the existing elevator control system are many, the control system fails in all the years of occurrence and serious casualty accidents of the existing elevator control system. Therefore, an elevator safety monitoring system independent of an elevator control system is urgently needed, the running state of the elevator is monitored on line in real time, and when an abnormal state is found, safety control measures are actively taken, so that the life and property safety of people is protected to the maximum extent.

In the detection of the elevator, the performance detection of the elevator steel wire rope is one of necessary items, the performance of the elevator steel wire rope can be aged, abraded and the like in the operation process of the elevator, so that the elevator steel wire rope is broken, lost and the like, and potential safety hazards are generated in the operation of the elevator; and the balance coefficient of elevator decides the stability of elevator operation, when the balance coefficient value of elevator is improper, will influence the holistic operation of elevator, produce the potential safety hazard, to foretell problem, need carry out regularly inspection and maintenance work to the elevator, present most elevator management company carries out the inspection and the maintenance work of elevator through artifical shut down, need great manpower and material resources, inspection work is very loaded down with trivial details, need investigate each work area of elevator, the mode of this kind of artifical shut down inspection can't carry out real-time data's detection to the elevator, the real-time running condition of elevator can't learn, consequently the absolute safety of elevator when the operation still can't be guaranteed to this kind of method of regularly artifical inspection maintenance, simultaneously because of the elevator trouble that artifical incomplete investigation or work fault lead to.

The elevator door system fault is one of common faults of an elevator, usually, the elevator door lock loop is shown to have a fault, the elevator door lock loop is formed by connecting a car door loop and a hall door loop of each layer in series, in this case, as long as one of the car door loops or one of the hall door loops is disconnected, the whole elevator door lock loop is disconnected therewith, fault diagnosis is to be performed on an elevator door, it is generally required to determine whether the car door loop or the hall door loop of which layer has the fault, and therefore, the detection principle adopted by the existing fault detection device is generally that: the elevator door lock loop is in short circuit, loop resistance measurement is carried out through a universal meter, when actual detection is carried out, the car door loop is in short circuit, resistance measurement is carried out through the universal meter, whether the car door loop is in fault or not is determined, if not, the elevator is controlled to operate, and each hall door loop is detected layer by layer through the universal meter in the operation process, so that a layer to which the specific hall door loop is in fault can be found out. The detection technology consumes a large amount of manpower, has low detection efficiency and high working strength, delays the operation time of the elevator and causes inconvenience to users.

in the elevator routine maintenance process, the field operation personnel are required to judge the oil quantity in the elevator guide rail lubricating oil box through naked eyes, and the following defects exist:

1. When the oil box is checked, the cover of the oil box needs to be manually opened to check the oil quantity, so that the oil quantity judgment is troublesome, and errors are easily generated in the judgment due to insufficient light in an elevator shaft;

2. because elevator maintenance operation project is various, easy oil leakage is carried out during operation personnel maintenance operation, and elevator service environment is different, and high-rise commercial building elevator operation is very frequent, probably causes lubricating oil consumption too big, leads to the lubricated not enough problem of elevator, can't judge the cycle of check oil mass, need expend manpower frequently to go to check the oil mass and refuel, can not ensure in addition that the oil mass can both reach the standard in all oil boxes.

With the development of elevators, the number of elevators is rapidly increasing, and a speed limiter is one of necessary safety parts of each traction type elevator, so that the workload of speed limiter verification is huge in terms of number. Secondly, the speed limiter passes through a steel wire rope, the tension wheel and the safety tongs form one of important safety protection systems of the elevator, the elevator is stopped firstly during verification, and the speed limiter and the steel wire rope are separated by a tool, so that preparation work required by field verification is more, and the verification time is longer. Finally, the installation positions of the elevator speed limiters are different, a common traction type elevator is installed on a machine room, and for an elevator without the machine room, the speed limiters are installed on an elevator shaft and a pit. Therefore, according to the inspection method of the inspection standard after the revision, the maintenance unit and the inspection personnel confirmed on the site must be on the site at the same time, and both sides cannot perform other regular inspection and test work in the whole process, so that the work needs to consume a large amount of manpower and time, and great challenges are brought to the manpower resources of the maintenance unit and the inspection organization.

Most of the existing safety tongs are of a mechanical control structure, the general elevator carries out safety tong overhaul work once a year, the safety tongs are difficult to perceive when in fault in the operation process of the elevator in this year, the elevator safety tongs serve as the most critical line of defense of elevator safety, once the fault occurs, the consequence is very serious, the existing part of the safety tongs is provided with a safety tong monitoring device with an electronic detection function, the detection structural design is difficult to meet the actual use requirement, and the problems that the accuracy of detected data is not high and the like exist.
