Description
Technical Field
The utility model relates to an elevator security protection technical equipment field, concretely relates to elevator sedan-chair door sword touches early warning device with layer door lock gyro wheel mistake.
Background
At present, the well-known elevator door opening and closing device is composed of a door machine, a car door knife, a landing door lock roller and the like. When the elevator operates, layer door lock gyro wheel passes through between two sedan-chair door sword, for guaranteeing that sedan-chair door sword and layer door lock gyro wheel can not touch each other in the operation, sedan-chair door sword and layer door lock gyro wheel must keep the certain interval on being on a parallel with switch door direction of motion, and this interval generally is 5 ~ 10 mm.
The abrasion and the displacement of related parts of the elevator can cause the distance to be reduced, and finally, a car door knife can be contacted with the side surface of a landing door lock roller when the elevator runs, so that the action of an electric safety device for verifying the closing state of the landing door is caused, and the fault of sudden stop of the elevator is caused. According to authoritative data of the Changsha market supervision and management bureau, 96366 elevator emergency treatment centers in 2018 commonly treat emergency events 3958 such as trapped people faults and the like to rescue 9715 trapped people, and the proportion of elevator trapped people accidents caused by the faults of a door system is 16.76%; in 2018, the elevator emergency disposal platform of the special equipment emergency disposal center 96333 in Hangzhou city develops elevator trapped person fault disposal 7584 to save 15312 trapped persons, and the proportion of elevator trapped person accidents caused by the door system faults is 19.54%. The elevator door system fault analysis method has the advantages that the reason of elevator people trapping accidents is analyzed, except for non-equipment factors such as power failure, unhygienic elevator riding and the like, the door system fault is the most main fault type of elevator people trapping caused by an elevator equipment body, and most of the door system faults are caused by mistaken touch of a car door knife and a landing door lock roller when an elevator runs.
The reason analysis that the car door sword and layer door lock gyro wheel take place the mistake and touch is as follows: when the elevator car stops at a landing, the landing door lock roller is positioned between two car door and car door knifes, and the door machine arranged on the car drives the car door and drives the landing door lock roller through the car door knifes so as to drive the landing door to open or close. When sedan-chair door, layer door were all closed, layer door lock gyro wheel was in between two sedan-chair door knifes and sedan-chair door sword and layer door lock gyro wheel side's distance generally is greater than 5mm to this guarantees that sedan-chair door knife can not bump mutually with layer door lock gyro wheel when passing through from layer door along with the car moves from top to bottom. When the elevator normally operates, the car door and the landing door must be closed, the car door knife makes vertical lifting motion along with the elevator car body relative to the landing door lock roller, and at the moment, the car door knife and the landing door lock roller are not allowed to touch each other. The elevator is used frequently as a main vertical transport tool in a building, and parts of the elevator inevitably generate abrasion, displacement, looseness and the like after long-time operation. If can not in time adjust, change corresponding spare part, sedan-chair door sword and layer door lock gyro wheel can change at the interval that is on a parallel with switch door motion direction, reduce when this interval and reach certain degree, must cause the elevator in service sedan-chair door sword and the unusual contact of layer door lock gyro wheel, sedan-chair door sword mistake promptly touches layer door lock gyro wheel, makes the electric safety device action of verifying elevator layer door closure state, causes the elevator to stop suddenly, and then leads to the elevator trapped accident. Lead to the boots loose or lead to causing car and sedan-chair door sword to rock in service after the shoe lining wearing and tearing if the car, sedan-chair door sword, layer door lock gyro wheel are not hard up to produce the displacement etc. all can lead to sedan-chair door sword mistake to touch layer door lock gyro wheel. The elevator falling accidents frequently reported on the medium are mostly caused by the accidents. However, due to space limitation, it is difficult to manually measure the distance between the car door vane and the landing door lock roller during the daily maintenance of the elevator, and the elevator is usually checked and adjusted after a trapped accident occurs. And specific fault points are not easy to be searched and eliminated one by one due to the fact that the layer door lock roller of each layer can be involved.
Chinese patent document discloses a "detection device for displacement of gate ball for elevator" utility model patent [ grant publication No.: CN 208150718U ], relating to the technical field of elevators. The device comprises a camera detection system for detecting displacement, wherein the camera detection system comprises a camera device, and the camera device is arranged on a car door vane. This "detection device of croquet displacement for elevator" can only judge qualitatively whether the croquet displaced, can not measure the displacement volume and carry out quantitative analysis by the accuracy, does not possess trouble early warning and maintenance prompt facility. And the scheme has the disadvantages of more complicated installation process, more complicated required components and higher difficulty in practical application. Because elevator parts do frequent mechanical motion during operation, the displacement is normal, and the occurrence of accidents such as people trapping of the elevator can be effectively prevented by carrying out quantitative analysis and early warning on the displacement of the layer door lock roller.
