Abstract
The invention discloses a device for preventing a wire rope from being tangled in a load-free retraction process. The device comprises a tightening device (1) and a detection device (2), wherein the tightening device (1) is mounted on a wire rope (3); the detection device (2) communicates with the tightening device (1) by means of a control device; and the detection device (2) is mounted on the wire rope (3), and is used for detecting the stressing degree of the wire rope and transmitting a control signal to the tightening device (1) through the control device. The device can make a forecast and send out an alarm for the tangling of the wire rope, and also can prevent the tangling of the wire rope, thereby effectively preventing the tangled wire rope from being used in the middle and late stages. The invention has the advantages of simple design structure and strong applicability, thereby greatly decreasing the accidents caused by the tangling of the wire rope and meeting the requirements.
Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of empty hook of steel rope that prevents is packed up the device of disorder cable.
Background technology
At present, crane rope is in the process that empty hook is packed up, because the effect of not hanging thing gravity, steel rope is in and tends to occur disorder cable under the relaxed state, causes after this steel rope to transfer.
Summary of the invention
The objective of the invention is, provide a kind of and judge by the sensor measurement pull of steel wire whether steel rope occurs becoming flexible, and then prevent that effectively the device of the phenomenon of disorder cable from appearring in steel rope.
In order to achieve the above object, the invention provides a kind of empty hook of steel rope that prevents and pack up the device of disorder cable.This device comprises: the detecting device that is installed on enclasp device on the steel rope, communicates by control setup and enclasp device; Described detecting device is installed on the steel rope, is used to detect the stressed degree of steel rope, and by control setup control signal is sent to enclasp device.
Wherein, described detecting device comprises: the sensor that is used to detect the stressed degree of steel rope; And be used for judging that according to the stress value of the current steel rope of sensor steel rope is tensioner state or relaxed state, if be relaxed state, then send the state identifier of control command to enclasp device.
Beneficial technical effects is: this device both can be predicted, report to the police at disorder cable, also can prevent disorder cable, avoided the steel rope disorder cable to enter the intermediary and later stages effectively.Project organization is simple, and is practical, reduced the accident that causes owing to disorder cable significantly, satisfies the demands.
Description of drawings
Fig. 1 is that the embodiment of the invention prevents that the empty hook of steel rope from packing up the structure drawing of device of disorder cable.
Fig. 2 is embodiment of the invention detecting device and enclasp device communication scheme.
Fig. 3 is an embodiment of the invention enclasp device work scheme drawing.
Accompanying drawing sign: 1, enclasp device; 2, detecting device; 3, steel rope; 4, elevator.
The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
At present, crane rope is in the process that empty hook is packed up, because the effect of not hanging thing gravity, steel rope is in and tends to occur disorder cable under the relaxed state, causes after this steel rope to transfer.And at this type of situation, present scheme (concrete structure as shown in Figure 1) is proposed, only need detecting device, control setup, enclasp device and corresponding match mechanism on the hoisting crane, judge by the sensor measurement pull of steel wire whether steel rope occurs becoming flexible, and then prevent that effectively the phenomenon of disorder cable from appearring in steel rope.
Concrete, steel rope is (as Fig. 2) in the process of packing up, the sensor of detecting device detects the steel rope stressing conditions constantly, if state identifier judges that steel rope is a relaxed state, control setup then sends signal and comes controlled hydraulic system to give the suitable power of holding tightly (as Fig. 3) of steel rope by enclasp device, and this moment, steel rope became the tensioner state by relaxed state so.So just the tensioner by the control steel rope prevents disorder cable, thereby avoids the accident that causes therefrom.On the contrary, when steel rope is detected as the tensioner state, this device is then inoperative.So just improve work efficiency greatly, also reduced job costs.
Claims (2)
1. one kind prevents that the empty hook of steel rope from packing up the device of disorder cable, it is characterized in that this device comprises: the detecting device (2) that is installed on enclasp device (1) on the steel rope (3), communicates by control setup and enclasp device (1); Described detecting device (2) is installed on the steel rope (3), is used to detect the stressed degree of steel rope, and by control setup control signal is sent to enclasp device (1).
2. the empty hook of steel rope that prevents according to claim 1 is packed up the device of disorder cable, it is characterized in that described detecting device (2) comprising: the sensor that is used to detect the stressed degree of steel rope; And be used for judging that according to the stress value of the current steel rope of sensor steel rope is tensioner state or relaxed state, if be relaxed state, then send the state identifier of control command to enclasp device (1) by control setup.
