Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 shows the elevator that comprises anti-elevator disorder cable device according to first embodiment of the present utility model;
Fig. 2 shows according to the indicating device in the anti-elevator disorder cable device of first embodiment of the present utility model.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Anti-elevator disorder cable device in the utility model comprises indicating device and elevator control circuit.Second state that this indicating device is used to indicate elevator to be in to allow first state that rotates and do not allow to rotate; This elevator control circuit is connected with this indicating device, is used for when elevator is in first state, allows elevator to rotate, and when this elevator is in described second state, forbids that described elevator rotates.Wherein, in first state, if by the elevator control circuit elevator is rotated, the steel rope on the elevator can disorder cable; In second state, if elevator is rotated, elevator can disorder cable occur owing to being unkitted the suspension hook suspender on the steel rope, and perhaps, the steel rope on the elevator has been fixed and has not allowed to rotate.Thereby above-mentioned indicating device avoided elevator in the workplace of being unkitted the suspension hook suspender because of the maloperation disorder cable.
As shown in Figure 1, the elevator that comprises anti-elevator disorder cable device according to first embodiment of the present utility model comprises elevator case 7 and reel 5.Elevator case 7 is horizontally disposed cube shaped in the present embodiment, and its top is provided with opening, axially is provided with center shaft along it, and reel 5 is arranged on this center shaft, and can rotate around center shaft under the control of elevator control circuit.Steel rope 3 is wrapped on this reel 5, and in the present embodiment, the fag end of this steel rope 3 is provided with set pin 31, convenient fixedly steel rope 3.When having adorned the suspension hook suspender on steel rope 3, along with the rotation of reel, steel rope 3 stretches out downwards or upwards withdrawal gradually, plays the effect of control suspender.
As can be seen from Figure 1, in the present embodiment, anti-elevator disorder cable device also comprises anchor fitting 1, this anchor fitting 1 is arranged on the elevator case 7 of elevator, connector portions with fag end of the steel rope 3 that is used for fixing on the reel 5, like this, when the steel rope 3 on elevator is not adorned suspension hook and suspender, can be easily the fag end of steel rope 3 be fixed on the connector portions of this anchor fitting 1, have avoided using in the prior art rope cable wire end to be fixed to the troublesome operation of hoisting crane.Preferably, as shown in Figure 1, in the present embodiment, this connector portions is a snap close 11, and it is simple in structure, be set on the fag end of steel rope 3, and fixing by set pin 31.More preferably, this anchor fitting 1 also comprises chain 12, and an end of this chain 12 is fixed on the elevator case 7, and the other end is connected with this snap close 11, is more convenient for being connected of fag end of snap close 11 and steel rope 3.
In addition, this connector portions also is used for optionally engaging with indicating device simultaneously, is appreciated that, when this connector portions engages with indicating device, elevator is in first state that above-mentioned permission is rotated, when this connector portions when indicating device is thrown off, elevator is in above-mentioned second state that rotates of not allowing.That is to say that when having only the operator that connector portions is engaged with indicating device, indicating device can be indicated first state, make the control of elevator control circuit allow elevator to rotate; And as long as the operator with the disengagement of this connector portions and indicating device, no matter this connector portions engages with the fag end of steel rope 3 still not and any means for engaging, indicating device all can be indicated second state, forbids the rotation of elevator.Thereby make this anchor fitting 1 play fixing effect simultaneously and cooperate with the indication elevator whether be in the effect that allows the state that rotates with indicating device.In present embodiment, as shown in Figure 2, show according to the indicating device in the anti-elevator disorder cable device of first embodiment of the present utility model.Just, snap close 11 except on the fag end that is used to be set in steel rope 3 with fixing steel rope 3, also be used for optionally engaging with indicating device, indicating device is indicated first state when engaging with snap close 11, indicate second state when being separated with snap close 11.
Preferably, indicating device is the sensor device 2 that is arranged on the elevator case 7, the output lead of its upper sensor is connected to the elevator control circuit, more preferably, in the present embodiment, this sensor device 2 comprises near switch, can certainly comprise other forms of sensors such as travel switch, photoelectric switch.When connector portions engaged with sensor device 2, this sensor device 2 triggered first status signal of indication first state, and when sensor device 2 was thrown off, this sensor device 2 triggered second status signal of indication second state in connector portions.The elevator control circuit allows or forbids the rotation of elevator according to first status signal and the control of second status signal.Like this, just realized that the automatic sensing elevator is in first or second state, avoided the error of the control that artificial judgement causes.
Certainly, in according to other embodiment of the present utility model, according to actual conditions, indicating device also can be hand switch or human-computer interaction interface, and this hand switch or human-computer interaction interface are connected with the elevator control circuit.Suspension hook and suspender are housed and when allowing to rotate on elevator, the operator operates hand switch or sets on human-computer interaction interface, export to elevator control circuit first status signal or second status signal, make the elevator control circuit control the rotation that allows and forbid elevator respectively according to first status signal and second status signal.Utilize hand switch or utilize the mode of interpersonal interactive interface to make that operation is more flexible, and implement easier economy.
Be appreciated that by mentioned earlier the utility model not only provides a kind of anti-elevator disorder cable device, also correspondingly simultaneously provide a kind of elevator that comprises above-mentioned any anti-elevator disorder cable device.In addition, the utility model also provides a kind of hoisting crane, and it comprises the elevator of the described a kind of anti-elevator disorder cable device of the above-mentioned the application of comprising.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
