Abstract
The invention provides an elevator safety protection device. The elevator safety protection device is characterized by comprising a traction steel wire rope, an elevator car, a traction machine, a detection unit for detecting movement of the elevator car and sending a detection signal, a control execution unit for receiving the detection signal and clamping the traction steel wire rope and a counterweight device. When the elevator car moves abnormally, the detection unit sends the detection signal to the control execution unit, the control execution unit clamps the traction steel wire rope to enable an elevator to stop emergently, and accidents are avoided.
Description
Technical field
The present invention relates to a kind of safety protection apparatus for elevator.
Background technology
After elevator stops, when lift car is positioned at a certain position, may there is the situation of improper movement up or down, cause safety misadventure.For example, when elevator is in flat bed, elevator door is opened, and takes the people of elevator when turnover elevator, and in the situation that there is no manual operation, slippage up or down occurs lift car, causes possibly people by the accident of lift car and the shearing of hoistway lift door frame.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of when there is up or down improper mobile in lift car the safety protection apparatus for elevator of stop car.
For achieving the above object; the invention provides a kind of safety protection apparatus for elevator; it is characterized in that, comprising: traction steel-cable, lift car, towing machine, for detection of the detecting unit that moves and send detection signal of described lift car, for receiving described detection signal and clamping control performance element, the counterweight of described traction steel-cable.
Particularly, when described lift car moves up or down, described detecting unit sends detection signal, described control performance element receives signal and is judged, if the result of judgement is when elevator normally starts or people is the operation of carrying out, control performance element and be failure to actuate, now lift car can free motion; Otherwise, if the result of analyzing is lift car to be occurred improperly when mobile, control performance element and move and clamp traction steel-cable, thereby make lift car stop, prevent that lift car is moved further to avoid the danger of generation personnel shearing.
Preferably, described detecting unit is Magnetic Induction device or encoder apparatus.
More preferably, described detecting unit is arranged on described lift car or is arranged on described towing machine or is arranged on described lift car and moves up and down on the motion path of described traction steel-cable partly.
Preferably, described control performance element is the electromagnetic type wire holder with control circuit board, and described electromagnetic type wire holder is arranged on described lift car, and the motion path of described traction steel-cable is through described electromagnetic type wire holder.When lift car is under normal operating condition, described control performance element and described traction steel-cable no touch; When lift car is improper mobile status, described control performance element will clamp traction steel-cable immediately, make lift car stop.
Owing to adopting technique scheme, compared to prior art, the present invention has the following advantages: when improper movement occurs lift car, detecting unit sends to control performance element by detection signal, control performance element and clamp traction steel-cable, make elevator emergency stop, avoid having an accident.
Accompanying drawing explanation
Fig. 1 is the structural representation of safety protection apparatus for elevator of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Refer to Fig. 1; the invention provides a kind of safety protection apparatus for elevator, comprising: traction steel-cable 1, lift car 2, towing machine 3, for detection of the detecting unit that moves and send detection signal 4 of described lift car 2, for receiving described detection signal and clamping control performance element 5, the counterweight 6 of described traction steel-cable 1.Wherein, described detecting unit 4 is Magnetic Induction device or encoder apparatus, it can as shown in the present embodiment Fig. 1, be arranged on as described on lift car 2, or also can be arranged on described towing machine 3, or be arranged on described lift car 2 and move up and down on the motion path of described traction steel-cable 1 of part.Described control performance element 5 is the electromagnetic type wire holder with control circuit board, and described electromagnetic type wire holder is arranged on lift car 2, and the motion path of described traction steel-cable 1 is through described electromagnetic type wire holder.
When lift car 2 moves up or down, described detecting unit 4 sends detection signal to controlling performance element 5.Described control performance element 5 receives signals and is judged, if to be elevator normal starts or when people is the operation of carrying out, control performance element 5 and be failure to actuate for the result of judgement, now lift car 2 can free motion; Otherwise, if the result of analyzing is lift car 2 occur improper when mobile, control performance element and move and clamp traction steel-cable 1, thereby make lift car 2 stops, prevent that lift car 2 is moved further dangerous or other safety misadventures of avoiding generation personnel to shear.
