Abstract
The invention discloses an elevator structure. According to the elevator structure, a detection unit can send a detection signal to a control execution unit when a lift car moves, and the control execution unit can analyze and judge after receiving the detection signal. When the control execution unit judges that the movement of the lift car is normal operation or is generated due to human factors, the control execution unit does not act and is not in contact with a steel wire rope of a speed governor, and the steel wire rope of the speed governor is allowed to move along with the movement of the lift car, namely the movement of the lift car cannot be influenced; and when the control execution unit judges that the movement of the lift car is unintentional movement, the control execution unit acts to clamp the steel wire rope of the speed governor so as to ensure that the steel wire rope of the speed governor cannot move but the lift car moves at this movement, thus a pair of bidirectional safety tongs is triggered to stop the lift car which moves unintentionally so as to prevent a falling accident of the lift car.
Description
?
Technical field
the present invention relates to a kind of elevator structure.
?
Background technology
in prior art, occur involuntaryly when mobile at the car of elevator, can cause the danger of falling.
?
Summary of the invention
the purpose of this invention is to provide a kind of lift car that can detect involuntary movement the elevator structure of stop car immediately occur, avoid the danger of falling.
for achieving the above object, the technical solution used in the present invention is: a kind of elevator structure, comprise can lifting car, can drive the hoist ropes of described car lifting, the towing machine of walking around and can driving this hoist ropes to move for described hoist ropes, speed limiter wire rope, with described speed limiter wire rope, be connected can be when the clamped motionless and described car of this speed limiter wire rope be moved stop live the bidirectional safety tongs of this car, can when being moved, send described car the detecting unit of detection signal, then the detection signal that can receive described detecting unit analyzes the control performance element of judgement, when the analysis of described control performance element is judged movement that described car occurs and is for the normal operation of this car or people carry out mobile, this control performance element keeps not contacting with described speed limiter wire rope, it is involuntary when mobile judging in the analysis of described control performance element movement that described car occurs, this control performance element clamps described speed limiter wire rope and makes this speed limiter wire rope to move, now described bidirectional safety tongs is touched, and stop is lived the car of involuntary movement.
during concrete enforcement, described detecting unit adopts Magnetic Induction device or encoder apparatus, and this detecting unit is arranged on described car, or on described towing machine, or on the path of the hoist ropes that can move with described car.
during concrete enforcement, described control performance element adopts the electromagnetic type wire holder with control circuit board, and this controls performance element is arranged in the hoistway or machine room of elevator, corresponding to described speed limiter wire rope, removes the motion path with described bidirectional safety tongs connecting bridge.
the direction of the involuntary movement of described car is to face upward or downward.
utilization due to technique scheme, the present invention compared with prior art has following advantages: by detecting unit being set and controlling performance element, when the movement occurred at car is for normal operation or people carry out mobile, the control performance element is failure to actuate, keep not contacting with speed limiter wire rope, allow speed limiter wire rope to move along with the movement of car, i.e. the movement of car can not be affected; And be involuntary when mobile in the movement that car occurs, control the performance element action, clamp speed limiter wire rope to make this speed limiter wire rope to move, and now car is moving, bidirectional safety tongs is touched, and stop is lived the car of involuntary movement, prevents car generation falling accident.
?
The accompanying drawing explanation
accompanying drawing 1 is schematic diagram of the present invention.
?
The specific embodiment
further set forth structure of the present invention below in conjunction with accompanying drawing.
shown in Figure 1, a kind of elevator structure, comprise can lifting car 1, counterweight 3, car sheave 10, counterweight sheave 11, can drive the hoist ropes 4 of car 1 lifting, the towing machine of walking around and can driving this hoist ropes 4 to move for hoist ropes 4, velocity limiter main body wheel 5, governor tension pulley 13, speed limiter wire rope 6, the bidirectional safety tongs 7 be connected with speed limiter wire rope 6, detecting unit 8, control performance element 9, one end of hoist ropes 4 is fixed, after this hoist ropes 4 is walked around counterweight sheave 11 downwards, upwards walk around again track adjusting wheel 12, the traction sheave 2 of towing machine, then walk around again car sheave 10 downwards, the last fixing other end of hoist ropes 4, this elevator structure realizes that wiring compares 2:1 like this.Speed limiter wire rope 6 is upwards walked around velocity limiter main body wheel 5, and walks around governor tension pulley 13 downwards, and the two ends of this speed limiter wire rope 6 are connected with bidirectional safety tongs 7.This bidirectional safety tongs 7 can be clamped motionless at speed limiter wire rope 6, and car 1 is triggered while being moved, and stop is lived car 1.Detecting unit 8 adopts Magnetic Induction device or encoder apparatus, and in Fig. 1, this detecting unit 8 is arranged on car 1, for detection of the movement of car 1, and sends detection signal.In other embodiment, detecting unit can also be arranged on towing machine, or, on the path of the hoist ropes that can move with car, as long as the movement of car can be detected, sends detection signal.Control the electromagnetic type wire holder that performance element 9 adopts with control circuit board, this control performance element 9 is arranged in the hoistway or machine room of elevator, corresponding to speed limiter wire rope 6 except the motion path with bidirectional safety tongs 7 connecting bridges, for the speed limiter wire rope 6 that is fixedly clamped.
detecting unit 8 can send detection signal to controlling performance element 9 when car 1 is moved, and controls after performance element 9 receives detection signal and can analyze judgement.When controlling performance element 9 and judge movement that car 1 occurs and be for the normal operation of this car 1 or people carry out mobile by the detection signal of analyzing and testing unit 8, controlling performance element 9 is failure to actuate, controlling performance element 9 keeps not contacting with speed limiter wire rope 6, allow speed limiter wire rope 6 to move along with the movement of car 1, i.e. the movement of car 1 can not be affected; And analyze when controlling performance element 9 that to judge movement that car 1 occurs be involuntary when mobile, the intentional movement here refers to such an extent that be that non-road-holding property moves, be abnormal running or the non-artificial movement of carrying out, the direction of involuntary movement can be upward, also can be down, this controls performance element 9 actions, clamping speed limiter wire rope 6 makes this speed limiter wire rope 6 to move, and now car 1 is moving, bidirectional safety tongs 7 is touched, stop is lived the car 1 of involuntary movement, prevents car generation falling accident.
