[0039] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0041] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0042] See also Figure 1The present invention provides a device for identifying the rotation direction of a flying shear, comprising a detection module and a judgment module. The detection module comprises a first sensor 1, a second sensor 2 and a sensing block 3. The first sensor 1 and the second sensor 2 are both arranged at the end of the flying shear lead-out shaft 4, and the two are arranged at an angle less than 180° and greater than 0°; the sensing block 3 is arranged at the rotating part 5 of the flying shear, and rotates synchronously with the rotating part 5. During the rotation of the flying shear, the sensing block 3 is driven to contact the sensing areas of the first sensor 1 and the second sensor 2. Since the judgment module is electrically connected to the first sensor 1 and the second sensor 2, when the sensing block 3 rotates to the sensing area of ​​the first sensor 1, the first sensor 1 sends a first signal to the judgment module; when the sensing block 3 rotates to the sensing area of ​​the second sensor 2, the second sensor 2 sends a second signal to the judgment module. Since there is a time difference between the first signal and the second signal received by the judgment module, the judgment module can determine the rotation direction of the flying shear according to the first signal and the second signal, which solves the shortcomings caused by the manual judgment of the rotation direction lock of the flying shear, is conducive to improving the accuracy and efficiency of the judgment of the rotation direction of the flying shear, and is conducive to avoiding the occurrence of pile steel accidents.

[0043] It should be noted that the end of the flying shear lead-out shaft 4 is in a non-rotating state and does not rotate along with the rotating part 5 of the flying shear.

[0044] Exemplarily, the first sensor 1 and the second sensor 2 include but are not limited to being configured as proximity switches and the like.

[0045] In one embodiment of the present invention, in order to enable the operator to intuitively see the identification result, the judgment module is electrically connected to the display module. After the judgment module determines the rotation direction of the flying shear, the result is output to the display module and displayed by the display module.

[0046] Exemplarily, the display module includes but is not limited to being configured as a display screen, etc.

[0047] In one embodiment of the present invention, when the judgment module determines that the rotation direction of the flying shear is wrong, the judgment module is electrically connected to an early warning module to draw the attention of the operator. The early warning module warns the operator when the judgment module determines that the rotation direction of the flying shear is wrong.

[0048] Exemplarily, the early warning module includes but is not limited to being set as a buzzer, a three-color light, etc.

[0049] In one embodiment of the present invention, the judgment module includes a trigger and a timer. The trigger is used to receive the first signal and the second signal. When the trigger receives the first signal, the timer starts the delay; when the trigger receives the second signal, the timer stops the delay. By setting the trigger and the timer, the time when the induction block 3 rotates from the first sensor 1 to the second sensor 2 can be determined. It should be noted that in order to ensure the accuracy of the delay time, the first signal and the second signal both take the rising edge.

[0050] In one embodiment of the present invention, if the preset delay time of the timer is reached and the trigger receives the second signal, that is, the time for the induction block 3 to rotate from the first sensor 1 to the second sensor 2 is within the preset delay time, then the rotation direction of the flying shear is determined to be correct. If the preset delay time of the timer is reached and the trigger does not receive the second signal, that is, the time for the induction block 3 to rotate from the first sensor 1 to the second sensor 2 exceeds the preset delay time, then the rotation direction of the flying shear is determined to be wrong.

[0051] In summary, the scheme of this embodiment is to set the first sensor and the second sensor at the end of the flying shear lead-out shaft, and the rotating part of the flying shear is provided with a sensing block that rotates synchronously therewith, and the sensing block can contact the first sensor and the second sensor respectively, so that the first sensor and the second sensor send the first signal and the second signal to the judgment module. Since the first sensor and the second sensor are set at an angle less than 180° and greater than 0°, the rotating part of the flying shear rotates in different directions, and the time intervals between the first sensor sending the first signal and the second sensor sending the second signal are different, so that the judgment module can determine the rotation direction of the flying shear according to the first signal and the second signal, which solves the shortcomings brought about by manual judgment of the rotation direction of the flying shear, is beneficial to improving the accuracy and efficiency of judging the rotation direction of the flying shear, and is beneficial to avoiding the occurrence of steel pile accidents.

[0052] The present invention also provides a method for identifying the rotation direction of a flying shear, which is applied to the above-mentioned device for identifying the rotation direction of a flying shear, and may include steps S110 to S120, which are described in detail as follows:

[0053] Step S110, acquiring a first signal and a second signal.

[0054] In one embodiment of the present invention, when the induction block 3 follows the flying shear rotating part 5 to move to the first sensor 1, the first sensor 1 sends a first signal to the judgment module. When the induction block 3 follows the flying shear rotating part 5 to move to the second sensor 2, the second sensor 2 sends a second signal to the judgment module.

[0055] Step S120, determining the rotation direction of the flying shear according to the first signal and the second signal.

[0056] In one embodiment of the present invention, since the first sensor 1 and the second sensor 2 are arranged at an angle less than 180° and greater than 0°, the directions of rotation of the flying shear rotating part 5 are different, and the time intervals between the first sensor 1 sending out the first signal and the first sensor 1 sending out the second signal are different, so that the judgment module can determine the rotation direction of the flying shear based on the first signal and the second signal.

[0057] In one embodiment of the present invention, when the first sensor 1 sends a first signal, the set end of the trigger receives the signal and outputs a delay signal to the timer to start delaying the timer. When the second sensor 2 sends a second signal, the reset end of the trigger receives the signal and outputs a delay stop signal to the timer to start and stop delaying the timer. The current real-time delay time of the timer is obtained, and the real-time delay time is compared with the preset delay time. If the real-time delay time is less than or equal to the preset delay time, it is determined that the rotation direction of the flying shear is correct; if the real-time delay time is greater than the preset delay time, it is determined that the rotation direction of the flying shear is wrong.

[0058] In one embodiment of the present invention, in order to determine the preset delay time, the method further includes steps S210 to S230, which are described in detail as follows:

[0059] Step S210 , obtaining the rotation speed of the sensing block 3 and the arc distance between the first sensor 1 and the second sensor 2 .

[0060] In one embodiment of the present invention, since the induction block 3 rotates synchronously with the flying shear rotating part 5, the rotation speed of the induction block 3 is the rotation speed of the flying shear rotating part 5. The rotation speed of the induction block 3 can be calculated by the following formula:

[0061]

[0062] Wherein, k represents the rotation speed of the induction block 3; n represents the rotation speed of the motor driving the rotating part 5 of the flying shear; i represents the mechanical transmission ratio of the motor; m represents the feedback value of the transmission device; and t represents the maximum feedback value (scale value) of the transmission device.

[0063] The arc distance between the first sensor 1 and the second sensor 2 can also be obtained by calculation.

[0064] Step S220, determining the rotation time of the sensor block 3 between the first sensor 1 and the second sensor 2 according to the rotation speed and the arc distance.

[0065] In one embodiment of the present invention, after determining the rotation speed of the flying shear rotating part 5 and the arc distance between the first sensor 1 and the second sensor 2, the rotation time of the sensing block 3 between the first sensor 1 and the second sensor 2 can be calculated, and the rotation time can be used as the delay time of the timer.

[0066] Step S230 , correcting the rotation time to obtain a preset delay time of the sensing block 3 between the first sensor 1 and the second sensor 2 .

[0067] In one embodiment of the present invention, due to the complex working conditions on site, in the actual operation, if the rotation time of the sensor block 3 between the first sensor 1 and the second sensor 2 determined according to the rotation speed and the arc distance is used as the delay time of the timer, an error will occur. In order to avoid the above situation, the rotation is corrected to determine the preset delay time of the sensor block 3 between the first sensor 1 and the second sensor 2. Specifically, refer to the following formula:

[0068]

[0069] In the formula, x represents the preset delay time of the timer; y represents the arc distance between the first sensor 1 and the second sensor 2; b represents the correction; and k represents the rotation speed of the sensor block 3.
