Description
Technical field
This utility model relates to lift technical field, particularly belongs to a kind of device for preventing elevator from falling.
Background technology
China's elevator industry grows out of nothing since after the founding of the state, from first license awarding in 1974 till now, and China's electricity
Ladder industry has become as elevator factory of the world, and either volume of production and marketing all reaches the whole world first.And China in 2014 will implement " extraordinary
Equipment safety law ", manufacture with legal norm elevator, install and after-sale service further.The enforcement of special safety equipment method is " extraordinary
Equipment safety law " elevator industry will be caused great vibrations, force elevator industry to attain a yet higher goal, entirely from quality and management
The manufacture of face monitoring elevator, install, use and repair and maintenance after-sale service；China's elevator will have earth-shaking change in 2014,
On the one hand this change is owing to the enforcement of " special safety equipment method " causes the change of industry and the upgrading of product and the liter of repair and maintenance
Level；The technology having renewal is applied and is promoted elevator industry development to receive a fresh impetus by second aspect.
Existing elevator drop preventer depends in elevator lifting system, realizes anti-fall effect by software intelligent decision
Really, but elevator accident the most all causes due to external force or system fault, thus anti-in depending on elevator lifting system
Arrest systems is the most unreliable, makes mistakes itself some systems or steel wire cable directly ruptures the falling accident caused, it is impossible to rise
To due effect.
Utility model content
The purpose of this utility model there is provided a kind of device for preventing elevator from falling, overcomes the deficiencies in the prior art, at electricity
The lower section of ladder every layer of case stop position arranges mechanical anti-falling structure, and anti-falling structure includes base plate, block and controller, elevator
Under normal operation, the absorption of the electric magnet on block base plate makes it be vertical state, and motor housing is except starting and stopping simultaneously
When, have outside acceleration, and other state acceleration are zero, in the case of elevator has an accident, due to action of gravity electricity
Cabinet there will be a lasting acceleration, and this is acceleration detecting when this lasting acceleration being detected, controls electricity
Magnet decontrols base plate, and that effect can be drawn to rapidly go to is horizontal due to the hydraulic supporting plate gravity being provided above and tail springs for base plate
State, makes hydraulic supporting plate be supported on elevator bottom portion, prevents used during elevator falling, and mechanical structure is reliable and stable, due to this fall arrest
Outside device is independent of elevator lifting system, therefore, system itself is made mistakes or steel wire cable directly ruptures falling of causing
Accident, has good preventive effect, improves prior art elevator safety hidden danger, accords with the demands of the market.
For solving the problems referred to above, technical solution adopted in the utility model is as follows:
A kind of device for preventing elevator from falling, including lifting tunnel plate, elevator case, driving means and counter weight device, described liter
Being evenly equipped with several anti-falling structures on fall tunnel plate, described anti-falling structure includes base plate, block and controller, described base plate
Centre position is hinged and connected to lift in tunnel plate, and described base plate is connected by hydraulic cylinder near one end of elevator case support
Plate, the other end is connected with stop bottom by spring, and described block is arranged in lifting tunnel plate, and is positioned at the base plate other end
Surface, described block is provided with electric magnet near a survey of elevator case, and described controller includes control module and power supply, institute
The electric magnet stated is connected with control module, and described control module is also associated with acceleration detecting, described acceleration
Detection device is arranged in elevator case.
Further, on described base plate, the one end near elevator case is additionally provided with the iron block or permanent magnet coordinated with electric magnet.
Further, described anti-falling structure is positioned at the lower section of elevator every layer of stop position of case.
Further, it is connected by remote transmitting device between described control module and acceleration detecting.
Compared with prior art, implementation result of the present utility model is as follows for this utility model:
A kind of device for preventing elevator from falling described in the utility model, mechanical structure is reliable and stable, due to this falling proof device
Outside independent of elevator lifting system, therefore, system itself is made mistakes or steel wire cable directly ruptures the falling accident caused,
There is good preventive effect, improve prior art elevator safety hidden danger, accord with the demands of the market.

Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited only to these examples, for de-
On the premise of present inventive concept, within any improvement of doing all falls within protection scope of the present invention.
As it can be seen, a kind of device for preventing elevator from falling described in the utility model, including lifting tunnel plate 1, elevator case 2,
Driving means 3 and counter weight device 4, described lifting tunnel plate 1 is evenly equipped with several anti-falling structures 5, described anti-falling structure 5
Including base plate 6, block 7 and controller 8, described base plate 6 centre position is hinged and connected to lift in tunnel plate 1, described base plate 6
There is gripper shoe 62 upper connection by hydraulic cylinder 61 near one end of elevator case, and the other end is connected bottom block 7 by spring 72,
Described block 7 is arranged in lifting tunnel plate 1, and is positioned at directly over the base plate other end, and described block 7 is near elevator case
One survey is provided with electric magnet 71, and described controller 8 includes control module and power supply, and described electric magnet 71 is with control module even
Connecing, described control module is also associated with acceleration detecting 9, described acceleration detecting 9 is arranged on elevator case 2
In；On described base plate 6, the one end near elevator case is additionally provided with the iron block coordinated with electric magnet 71 or permanent magnet 63；Described is anti-
Pendant structure 5 is positioned at the lower section of every layer of stop position of elevator case 2；By remote between described control module and acceleration detecting
Journey transmitting device connects；Arranging mechanical anti-falling structure in the lower section of elevator every layer of stop position of case, anti-falling structure includes the end
Plate, block and controller, under elevator normal operation, the absorption of the electric magnet on block base plate makes it be vertical state, electricity simultaneously
Cabinet is except having acceleration in addition to starting and stop when, and other state acceleration are zero, when elevator has an accident
In the case of, owing to action of gravity motor housing there will be a lasting acceleration, this is that acceleration detecting detects this
During lasting acceleration, controlling electric magnet and decontrol base plate, base plate is due to the hydraulic supporting plate gravity being provided above and tail springs
Effect can be drawn to rapidly go to level, make hydraulic supporting plate be supported on elevator bottom portion, prevent used during elevator falling.
