Description
[technical field]
The utility model relates to a kind of elevator load detecting device.
[background technology]
Along with the develop rapidly of China's economy, skyscraper is rised sheer from level ground like the mushrooms after rain.Elevator is the indispensable device of skyscraper, its transport facility as a kind of uniqueness has obtained popularizing rapidly and development, elevator also is the higher electromechanical integrated product of a kind of technology content simultaneously, because it has fully used microcomputer control, intelligence and electrical and electronic technology, so the content height that possesses skills, develop fast characteristics.When high-rise is more and more higher to the requirement of elevator performance and control system, require its corresponding safety system also more advanced, more reliable.
Overload protection function is a kind of important defencive function of elevator, and the elevator lot of accident that newpapers and periodicals and TV etc. are exposed by the media all lost efficacy relevant with the lift car overload warning.Particularly elevator without the driver operation state under because people do not know the elevator key property, run into coaster or other improper operating conditions, mostly blindly in the car toward flight, thereby cause the tragedy that much should not occur.And overload protection function all is very important for the goods of the personal safety of guaranteeing the boarding personnel and elevator conveying and lift facility inherently safe etc.
Overload protection device in use, for various reasons, its validity and precision can change unavoidably.If this apparatus function lost efficacy or load carrying ability also can't move above 110% rated load, just there has been potential safety hazard in elevator.For guaranteeing that every elevator has reliable, accurate, a stable overload protection device; elevator maintain and protection company will regularly safeguard this device and test; but in practical operation for various reasons; the Application standard counterweight is comparatively limited as the overload condition of the function that detects of load or other load, many times just may not find enough load to test.So no matter elevator maintenance company might as well; or special equipment inspection mechanism might as well; overload protection to elevator has certain ignorance; whether the warning function that also is at most action detection switch is effective; see simultaneously whether satisfy relevant criterion to the requirement of elevator overload, but when reporting to the police represented load capacity whether to satisfy the requirement of standard just unknown.
Can realize that without instrumentation no-load detects the elevator overload warning function in the market.The check of elevator overload alarm and protection function is a blind area now, also is the major cause that there is potential safety hazard in elevator even has an accident.
The day for announcing is on 07 18th, 2012, notification number is the Chinese patent of CN202337623U, a kind of lift load detector is disclosed, its main points are, it comprises support, lever, bearing pin, strut bar, upper support seat, all is processed with the pin-and-hole that matches with bearing pin on support, the lever, and lever is hinged by bearing pin and support, strut bar one end links to each other with support, and the other end links to each other with upper support seat.This patent is based on lever principle and designs, and its upper support seat need act on the upper bank of hoistway door, so the upper bank of hoistway door must provide enough antagonistic forces; Yet in practical operation, the upper bank of hoistway door possibly can't be realized this function, for example: and bank undercapacity on some hoistway door, can't bear bearing force; Bank is too narrow again or on some hoistway door, can't support this detector upper support seat, and causing elevator load to detect can't effectively carry out; This detector volume is too huge in addition, and preponderance is not easy to carry; Should be to lightness, miniaturization development.
