Description
Technical field
The utility model relates to a kind of sedan-chair top Weighing type overload protection device, particularly a kind of electronics sedan-chair top Weighing type overload protection device.
Background technology
Along with the develop rapidly of China's economy, improving constantly of living standards of the people, the requirement of people to clothing, food, lodging and transportion--basic necessities of life is more and more higher.Elevator is the necessary devices of skyscraper, and the reliability of its corresponding safety system and stability in use will affect the security of the lives and property of elevator ride personnel.
Sedan-chair top Weighing type overload protection device is when lift car exceedes rated load, can send warning signal and make the safety device that car can not run.Existing Weighing type overload protection device is divided into mechanical type, rubber block formula and load sensor formula three kinds.But be no matter any in above-mentioned three kinds, its structure is all comparatively loaded down with trivial details, is unfavorable for the stability in use of product.
Utility model content
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides a kind of structure simple electronics sedan-chair top Weighing type overload protection device.
In order to achieve the above object, a kind of electronics sedan-chair top Weighing type overload protection device designed by the utility model, comprise fixing on the elevator car for connecting rope hitch plate and the sedan-chair head piece of hoist ropes, on described sedan-chair head piece, activity runs through a pair detection conduit, wherein all be socketed with rope hitch plate spring outward at each detection conduit, described rope hitch plate spring is positioned at the below of sedan-chair head piece, and one end and sedan-chair head piece surface phase apical grafting, the other end then with lift car phase apical grafting, described a pair detection conduit is provided with the detecting plate matched with it jointly, described detecting plate is positioned at the top of sedan-chair head piece, described rope hitch plate is fixed on this detecting plate, on described sedan-chair head piece, also activity is fixed with the differential transformer be connected with elevator control circuit ohm, the iron core of this differential transformer is connected with traction finer wire, the other end of this traction finer wire is led afterwards by pulley and detecting plate fixes.
The principle of work of above-mentioned a kind of electronics sedan-chair top Weighing type overload protection device: when after sedan-chair carrying; sedan-chair head piece on car is stressed and compress rope hitch plate spring; the iron core of differential transformer does horizontal axis along with the power of traction seizing wire and moves; differential transformer output voltage changes thereupon; namely the change of voltage signal is the change of car bearing capacity; when car bearing capacity reaches setting value; control circuit just sends the action of signal control vital circuit; car is not closed the door, overload light and the work of other suggestion devices.
As further technological selection, the concrete fixed sturcture of above-mentioned differential transformer on sedan-chair head piece is: on described sedan-chair head piece, offer two row's preset hole, this two rows preset hole is all in horizontal linear shape, gusset is equipped with in the arranged on left and right sides of described differential transformer, each described block gusset being equipped with strip hole and, to arrange preset hole corresponding, and through bolt assembly is fixed.This further preferably prevents middle differential transformer to be flexibly connected mutually with sedan-chair head piece between the two, and it is simple to be flexibly connected implementation, and stability in use is good.
A kind of structure simple electronics sedan-chair top Weighing type overload protection device provided in the utility model; it is by being converted into the change of differential transformer output voltage by the change of car bearing capacity; thus Drive and Control Circuit just sends the action of signal control vital circuit; car is not closed the door, overload light and the work of other suggestion devices.Integral structure is simple, and stability in use is good.
