Abstract
The invention discloses an elevator fall protective device, which comprises a detecting device for detecting a falling object and a protective device, wherein the detecting device is distributed and arranged in a hoistway of an elevator; and the protective device is arranged on side of the hoistway and ejects a protective net to stop and receive the falling object when the detecting device detects that the falling object exists. Compared with the prior art, the elevator fall protective device has more safe and effective protective measures and can effectively reduce accidents caused by fall of people into the hoistway during the operation of the elevator and improve the safety control during the operation of the elevator.
Description
Technical field
The present invention relates to the elevator safety technical field, personnel or object fall in particularly a kind of elevator hoistways detection and fender guard.
Background technology
At present, in the running process of elevator, open and car not under the situation at current floor at Room door, to the passenger and near operating personnel's protection be by service personnel warning sign and simple and easy guard rail to be set to prevent personnel's hoistway that falls.The protection of service personnel self is the raising on awareness of safety just, people or thing is not fallen and carries out the essence protection in the hoistway.When service personnel is neglected, cause easily self or near the operating personnel from the Room door of the opening hoistway that falls, cause personal casualty.In elevator industry, when once repeatedly appearing at Room door and opening, personnel fall into hoistway from door entrance, the Room because of carelessness and cause the accident of personal casualty.In brief, owing to do not have falling protecting device in the hoistway, there is being the people when Room door falls hoistway, to have very big potential safety hazard.
Summary of the invention
In order to overcome shortcoming of the prior art, the object of the present invention is to provide a kind of fender guard, when people or thing fall in the door of the hoistway Room, can make it stop tenesmus more safely, reduce personal casualty as far as possible.
The technical solution adopted in the present invention: a kind of elevator fall protective device; comprise the detecting device and the fender guard that are used to detect falling object; described detecting device is arranged evenly in elevator hoistways; described fender guard is installed in hoistway one side; and when detecting device has detected falling object, launch out guard net by this fender guard and connect falling object to block.
Above-mentioned detection device is made of a pair of a transmitting terminal and receiving end or reflection end, constitute one group by two pairs or more, according to the height of elevator hoistways and the distribution situation of stop number some set detecting devices is set in hoistway.The sustained height of stating elevator hoistways is provided with a set detecting device, and wherein at least one pair of detecting device is installed on Room door one side near hoistway, is used to detect falling object; At least one pair of detecting device is installed on rear wall one side near hoistway in addition, is used to detect the elevator operation conditions.
Above-mentioned fender guard comprises the guard net catapult-launching gear, place the guard net in the catapult-launching gear and be fixed on net hook on the well enclosure, and this fender guard is installed in a distance, below of detecting device.When detecting device detected falling object, described fender guard launched out guard net automatically and hooks the net hook that is positioned on the well enclosure, formed a flexible protective net in hoistway, was used to block connect falling object.
Above-mentioned fender guard also comprises the safety air bag that places well pit, and when detecting device detected falling object, the safety air bag of pit ejected automatically, further protected the safety of falling object.
Above-mentioned detection device and fender guard only just start work when hoistway door is opened, and when having personnel to fall hoistway, make elevator enter run-stopping status.
The present invention has more safe and effective safety method with respect to prior art, can reduce effectively in the running process of elevator because of personnel weigh down the contingency that well causes, and has improved the safety control in the running process of elevator.

The specific embodiment
Below in conjunction with accompanying drawing concrete structure of the present invention is further described.
As shown in Figure 1, elevator fall protective device of the present invention comprises the array detecting device 5,6 that places in the elevator hoistways, places the fender guard of a distance, detecting device below, and the car buffer 4 that places the hoistway bottom.Wherein:
Described detecting device is made of a pair of a transmitting terminal and receiving end or reflection end, constitute one group by two pairs or more, according to the height of elevator hoistways and the distribution situation of stop number some set detecting devices is set in hoistway.In the present invention, the sustained height of elevator hoistways is provided with a set detecting device, and wherein at least one pair of detecting device 5 is installed on Room door 2 one sides near hoistway, is used to detect falling object; At least one pair of detecting device 6 is installed on rear wall one side near hoistway in addition, is used to detect the elevator operation conditions.
Described fender guard comprises guard net catapult-launching gear 3, place the guard net 8 in the catapult-launching gear and be fixed on net hook 7 on the well enclosure, and this fender guard is installed in a distance, below of detecting device.When detecting device 5,6 had detected falling object, described guard net catapult-launching gear 3 ejected guard net 8 at once automatically, and hooked the net hook 7 that is positioned on the well enclosure, formed a flexible protective net in hoistway, was used to block connect falling object.
As shown in Figure 2, wherein the set-up mode of detecting device 5 and detecting device 6 is: detecting device 5 is arranged in the scope near Room door 2 direction well enclosures usually by two pairs or more detecting device is formed, and is mainly used in the personnel or the object that detect the hoistway that falls; Detecting device 6 is arranged on the well enclosure near rear side, is mainly used in the running condition that detects car 1.When doorway, the Room crashed into hoistway, according to being provided with at interval of detecting device 5 and detecting device 6,6 of normal conditions detecting device 5 and detecting devices had partly that detecting device produces detection signal as personnel or object.
When all detecting devices of same set detecting device 5 and detecting device 6 all do not have detection signal, represent that no personnel fall; Or when all detecting devices of same set detecting device 5 and detecting device 6 all had detection signal simultaneously, expression lift car 1 was moving.Guard net 8 in the guard net catapult-launching gear 3 all can not eject at this moment, and lift car 1 can normally operation in hoistway.
When in same set detecting device 5 or detecting device 6, having the part detecting device to produce detection signal; expression has the personnel of falling 9; then the guard net catapult-launching gear 3 of its below launches out guard net 8 obliquely according to detection signal; hook the net hook 7 that is arranged on hoistway wall and rear wall; form the guard net of a flexibility; block the personnel 9 that fall that connect, as shown in Figure 2.Lift car 1 enters run-stopping status when ejecting guard net 8, unless guard net catapult-launching gear 3 and guard net 8 reinstatements, elevator can not move.
Detecting device of the present invention and fender guard only just start work when hoistway door is opened, and when having personnel to fall hoistway, make elevator enter run-stopping status.In addition, described fender guard also comprises the safety air bag (not shown) that places well pit, and when detecting device detected falling object, the safety air bag of pit ejected automatically, further protected the safety of falling object.
