Referring to fig. 1 to 6, the cable basket exit recognition system provided by the present embodiment includes a cable guide basket ring, a signal acquisition device and a detection mechanism, and the connection relationship and the operation principle between the above parts will be specifically described below.

In this embodiment, the cable basket-out recognition system is disposed in the cable hanging device of the crane, and is configured to determine a basket-out phenomenon of the cable 2, that is, when the cable 2 penetrating through the cable guide basket ring 11 has the basket-out phenomenon, the cable basket-out recognition system can recognize the basket-out phenomenon. In the description of the present application, the phenomenon of "out of basket" can be understood as: when viewed in the hanging direction of the cable 2, it is assumed that the part of the cable 2 is located outside the projection area of the cable guide basket 11 in a state where the cable 2 is projected on the plane where the cable guide basket 11 is located, and after a predetermined time has elapsed, there is a case where the part of the cable 2 is located outside the projection area of the cable guide basket 11. That is, if the cable 2 has an out-basket phenomenon, the cable 2 is in the out-basket posture before and after the predetermined period of time.

In addition, the signal acquisition device is used for continuously acquiring the position signal of the cable 2, the position signal is received by the detection mechanism, and the detection mechanism executes the following judgment process after receiving the position signal:

the detection mechanism judges whether the cable 2 has a basket outlet phenomenon according to the position signal. If the detection mechanism determines that the cable 2 is currently in the basket outlet posture, the detection mechanism determines that the cable 2 is still in the basket outlet posture according to the position signal after delaying for t seconds, and then the detection mechanism confirms that the cable 2 is discharged from the basket.

In the present embodiment, the delay time t of the detection mechanism may preferably be 0.5 to 1 second, and if a portion of the cable 2 is outside the projection area of the cable guide basket 11 due to an impact on the hanger 5 or wind, the cable 2 is reset during the delay, and the swing amplitude is reduced thereafter due to energy loss, and then the detection mechanism determines whether the entire cable 2 is within the projection area of the cable guide basket 11 according to the position signal, and if it is determined that the entire cable 2 is within the projection area of the cable guide basket 11, it is determined that the entire cable 2 does not belong to the out-of-basket. Therefore, the situation that the detection mechanism falsely reports that the cable 2 is out of the basket due to the fact that the part of the cable 2 is instantaneously positioned outside the projection area of the cable guide basket ring 11 caused by the impact of the lifting appliance 5, wind power and the like is avoided.

In this embodiment, the signal acquisition device may be disposed at different positions, and different setting modes may be adopted for different setting positions of the signal acquisition device, which will be described in detail below.

In this embodiment, as shown in fig. 1 and fig. 2, the first setting position of the signal acquisition device may be: the signal acquisition device is arranged on a trolley 4 of the cable hanging device. Based on this setting position, the signal acquisition device may include two sets of camera mechanisms 3. In this embodiment, camera mechanism 3 can include the camera, and the camera can be common wireless camera among the prior art, guarantees the convenience of installation. In this embodiment, the camera continuously collects the primitives of the cable 2 and forms a position signal, so as to ensure the accuracy of the above recognition process.

It should be noted that the above-mentioned trolley 4 refers to a proprietary structure in the cable suspension device of the crane in the prior art, i.e. a mechanism capable of mounting the spreader 5 and running on the main beam of the crane. In this embodiment, the spreader 5 is installed below the cart 4 and can be lifted and lowered with respect to the cart 4 by being pulled by the pulleys on the cart 4, and the cable guide basket ring 11 installed on the cable storage basket 1 is installed above the spreader 5. In the case where the signal acquisition device is installed on the trolley 4 of the cable suspension device, since the camera mechanism 3 is installed on the trolley 4, the spatial positions of the camera mechanism 3, the cable guide ring 11 and the cable 2 are constantly changed in the operation process of the spreader 5. Therefore, in the embodiment, two groups of camera mechanisms 3 are adopted, which is equivalent to realizing three-dimensional imaging of the cable guide basket ring 11 and the cable 2, and the cable 2 swings without causing misjudgment of the detection mechanism, so that the accuracy of the identification process is ensured.

According to the above determination process of the detection mechanism, the identification process of the detection mechanism when the first setting position and setting mode of the signal acquisition device are adopted will be described in detail below.

The detection mechanism receives the primitive signals of the guide cable basket ring 11 and the cable 2 sent from the two groups of camera mechanisms 3, if the part of the cable 2 is judged to be positioned outside the projection area of the guide cable basket ring 11 and is delayed for t seconds, and the part of the cable 2 is still judged to be positioned outside the projection area of the guide cable basket ring 11 according to the primitive signals of the guide cable basket ring 11 and the cable 2, the detection mechanism confirms that the cable 2 is taken out of the basket.

However, the number of the imaging mechanisms 3 is not limited to two, and in order to further improve the accuracy of stereoscopic imaging, a larger number of the imaging mechanisms 3 may be added, that is, in the embodiment, at least two imaging mechanisms 3 may be provided.

In this embodiment, as shown in fig. 4 and 5, the second setting position of the signal acquisition device may be: the signal acquisition device is arranged on a lifting appliance 5 of the vertical cable device. Based on this setting position, the signal acquisition device may include a set of camera mechanisms 3. The camera mechanism 3 in the setting mode can also comprise a camera, and the camera can also be a common wireless camera in the prior art, so that the installation convenience is ensured. This arrangement also allows the camera pairs to continuously capture the elements of the cable 2 and form position signals to ensure the accuracy of the recognition process.

In contrast to the first signal pickup device installation method in which at least two sets of imaging mechanisms 3 are used, in this installation method, since the imaging mechanisms 3 are installed on the hanger 5 so that the positions of the imaging mechanisms 3 and the cable guide basket 11 are relatively unchanged, one set of imaging mechanisms 3 is used (however, this is not a limitation, and as in the first installation method, the number of imaging mechanisms 3 in this installation method may be at least one set).

According to the above determination process of the detection mechanism, the identification process of the detection mechanism when the second setting position and setting mode of the signal acquisition device are adopted will be described in detail below.

The detection mechanism receives the primitive signals of the guide cable basket ring 11 and the cable 2 sent from the camera mechanism 3, if the part of the cable 2 is judged to be positioned outside the projection area of the guide cable basket ring 11, and after a delay of t seconds, the detection mechanism still judges that the part of the cable 2 is positioned outside the projection area of the guide cable basket ring 11 according to the primitive signals of the guide cable basket ring 11 and the cable 2, and then the detection mechanism confirms that the cable 2 is taken out of the basket.

Further, since the distance between the imaging means 3 and the cable guide ring 11 is short when the imaging means 3 is installed on the hanger 5, and the angle of the imaging means 3 is the elevation angle, in the second installation position and installation method, if the detection means detects that the cable 2 has at least two specific inflection points as described below in the received primitive signal, it is possible to directly confirm that the cable 2 is out of the basket.

The two specific inflection points are respectively an inflection point where the cable 2 is connected to the cable guide basket 11 and an inflection point where a portion of the cable 2 outside the projection area of the cable guide basket 11 is sagged.

In this embodiment, the camera mechanism 3 is adopted, so that the signal acquisition device can continuously acquire primitive signals of the guide cable basket ring 11 and the cable 2, and real-time monitoring of the position of the cable 2 is ensured, and the camera mechanism 3 is adopted, so that on the basis of the above embodiment, the identification accuracy of the cable basket outlet identification system can be further improved in the following manner in the embodiment, which will be specifically described below.

In this embodiment, the detection mechanism may store an included angle between the camera and the vertical direction, and a distance between the two cameras under the condition that the signal acquisition device is provided with two or more cameras, as a criterion for determining whether the primitive signal of the cable 2 appears outside the cable guide basket 11.

Further, in the present embodiment, the detection mechanism may record the color, size, and shape of the cable guide basket 11, and the color, size, and shape of the cable 2 as auxiliary references. In particular the colour, size and shape of the grommet 11 may be designed differently from the colour, size and shape of the cable 2. For example, in the present embodiment, the outer side portion of the cable guide basket 11 may be painted, for example, red as a painted portion, and the cable guide basket 11 may be formed of a reinforcing bar having a rectangular cross section, and further, the cross-sectional size of the cable guide basket 11 may be larger than that of the cable 2. The design distinguishes the cable guide basket ring 11 from the cable 2, and facilitates the identification and judgment of the detection mechanism.

This embodiment still provides a cable device hangs down, and the cable device hangs down includes above-mentioned cable and goes out basket identification system, also includes the beneficial effect that above-mentioned cable goes out basket identification system and possesses, and the no longer repeated description here. The cable hanging device also comprises a trolley 4, a lifting appliance 5 which can lift relative to the trolley 4 and a control mechanism. The connection between the trolley 4 and the spreader 5 has been given in the above description and will not be described in detail. In addition, the detection mechanism is a detection mechanism of the crane, when the cable 2 is confirmed to be drawn out of the basket by the cable drawing identification system, the control mechanism controls the cable hanging device to enable the lifting appliance 5 to be properly lowered until the primitive signal shows that no primitive of the cable 2 exists outside the projection area of the cable guide basket ring 11 or the whole cable 2 is located in the projection area of the cable guide basket ring 11. Therefore, the cable hanging device in the embodiment can quickly solve the problem of cable out of the basket.

The embodiment further provides a crane, which comprises the above cable hanging device and also comprises the beneficial effects of the above cable hanging device, which are not described herein again.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all changes that can be made in the details of the description and drawings, or directly/indirectly implemented in other related technical fields, are intended to be embraced therein without departing from the spirit of the present application.
