For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In one aspect of the embodiments of the present application, a device for detecting edge damage of a steel coil clamp is provided. Figure 1 and 2As shown, in some embodiments, a steel coil clamp edge damage prevention detection device, the clamp 10 includes a first clamp arm 100, a second clamp arm 200 and a clamping motor 300, the clamping motor 300 is connected to the first clamp arm 100 and the second clamp arm 200, the clamping motor 300 is used to drive the first clamp arm 100 and the second clamp arm 200, and includes a first detection grating 40, a second detection grating 50, a signal processing unit 60 and a controller 70, wherein the first detection grating 40 is arranged on the first clamp arm 100, when the distance between the right side of the steel coil and the first clamp arm 100 is the first safety detection distance D1, the first detection grating 40 is triggered by the right side of the steel coil And generates a first detection signal; the second detection grating 50 is set at the second clamp arm 200, and when the distance between the left side of the steel coil and the second clamp arm 200 is the second safety detection distance D2, the second detection grating 50 is triggered by the left side of the steel coil and generates a second detection signal; the signal processing unit 60 is connected to the first detection grating 40 and the second detection grating 50, and is used to process the first detection signal and the second detection signal; the controller 70 is connected to the signal processing unit 60 and the clamping motor 300, and the controller 70 is used to control the clamping motor 300 to stop driving the first clamp arm 100 and the second clamp arm 200 when receiving the first detection signal or the second detection signal.

[0046] Specifically, Figure 1 As shown, the clamping motor 300 is used to drive the first clamp arm 100 and the second clamp arm 200 to open or close. When the first clamp arm 100 and the second clamp arm 200 are opened, the steel coil 80 can be released, and when the first clamp arm 100 and the second clamp arm 200 are closed, the steel coil 80 can be clamped. The clamping motor 300 is pivotally connected to one end of the first connecting rod 901 and the second connecting rod 902, respectively, and is used to drive the first connecting rod 901 and the second connecting rod 902 to move up and down; the first clamp arm 100 is pivotally connected to the other end of the first connecting rod 901, and the second clamp arm 200 is pivotally connected to the other end of the second connecting rod 902.

[0047] The clamping motor 300 is screwed to the fixing block 905 through the screw rod 904, and the fixing block 905 can be connected to the crane. The guide rod 906 can be inserted into the fixing block 905. When the clamping motor 300 drives the screw rod 904 to rotate, it can move up and down along the guide rod 906. The clamping motor 300 can be pivoted to the first connecting rod 901 through the fourth connecting rod 808. The clamping motor 300 can be pivoted to the second connecting rod 902 through the sixth connecting rod 910. The fixing block 905 can be pivoted to the first clamp arm 100 through the third connecting rod 907. The fixing block 905 can be pivoted to the second clamp arm 200 through the fifth connecting rod 909.

[0048] When the clamping motor 300 moves up and down, it can drive each connecting rod to rotate, and the cooperation of each connecting rod can drive the first clamp arm 100 and the second clamp arm 200 to open or close.

[0049] When the clamping motor 300 drives the first connecting rod 901 and the second connecting rod 902 to move up and down, the first connecting rod 901 and the second connecting rod 902 can drive the first clamp arm 100 and the second clamp arm 200 to open or close.

[0050] For example, when the first link 901 and the second link 902 move upward, the first clamp arm 100 and the second clamp arm 200 can be closed, and when the first link 901 moves downward, the first clamp arm 100 can be opened. When the second link 902 moves downward, the second clamp arm 200 can be opened.

[0051] The first clamp arm 100 and the second clamp arm 200 are connected to the clamp motor 300, and the controller 70 can be electrically connected to the clamp motor 300 and the signal processing unit 60 through wires, and the controller 70 can control the clamp motor 300 to start and stop. When the controller 70 controls the clamp motor 300 to stop, the clamp motor 300 stops driving the first clamp arm 100 and the second clamp arm 200, so that the first clamp arm 100 and the second clamp arm 200 cannot continue to move and remain in a stopped state (that is, the first clamp arm 100 and the second clamp arm 200 cannot continue to clamp the steel coil 80, so that the first clamp arm 100 and the second clamp arm 200 can maintain a safe distance from the steel coil 80); or, when the distance between the first clamp arm 100 and the second clamp arm 200 and the edge of the steel coil 80 is too close, the clamp motor 300 can drive the first clamp arm 100 and the second clamp arm 200 to open, so that the distance between the first clamp arm 100 and the second clamp arm 200 and the steel coil 80 can be adjusted.

[0052] When the controller 70 controls the clamping motor 300 to start, the clamping motor 300 can drive the first clamp arm 100 and the second clamp arm 200 to close, so that the first clamp arm 100 and the second clamp arm 200 can approach the steel coil 80 and clamp the steel coil 80 to ensure the stability and safety of the steel coil 80 during lifting.

[0053] In the embodiment of the present application, the controller 70 may be a PLC controller, and the output end of the signal processing unit 60 is connected to the input end of the PLC controller. Figure 2 As shown, by receiving the first detection signal and / or the second detection signal through the PLC controller, the start and stop of the clamping motor 300 can be controlled in real time, so that the right and left parts of the steel coil 80 can maintain a safe distance from the first clamp arm 100 and the second clamp arm 200 respectively, and direct contact and friction between the right and left parts of the steel coil 80 and the first clamp arm 100 and the second clamp arm 200 respectively can be avoided, thereby effectively preventing edge damage of the steel coil 80.

[0054] like Figure 1 and 2As shown, a first detection grating 40 and a second detection grating 50 are respectively arranged on the first clamp arm 100 and the second clamp arm 200. The first detection grating 40 and the second detection grating 50 can be respectively fixed to the first clamp arm 100 and the second clamp arm 200 by bonding or screwing. A first safety detection distance D1 is set between the first clamp arm 100 and the first detection grating 40. When the distance between the right side of the steel coil 80 and the first clamp arm 100 is the first safety detection distance D1, the first detection grating 40 is triggered by the right side of the steel coil 80 and generates a first detection signal. A second safety detection distance D2 is set between the second clamp arm 200 and the second detection grating 50. When the distance between the left side of the steel coil 80 and the second clamp arm 200 is the second safety detection distance D2, the second detection grating 50 is triggered by the left side of the steel coil 80 and generates a second detection signal.

[0055] The first safety detection distance D1 and the second safety detection distance D2 can be calculated in advance, for example, through on-site testing. For example, the distance between the right side of the steel coil 80 and the first clamp arm 100 can be the first safety detection distance D1 and the first detection grating 40 is just triggered at this time, and the position of the first detection grating 40 at this time is used as the formal installation position of the first detection grating 40. Similarly, the distance between the left side of the steel coil 80 and the second clamp arm 200 can be the second safety detection distance D2 and the second detection grating 50 is just triggered at this time, and the position of the second detection grating 50 at this time is used as the formal installation position of the second detection grating 50.

[0056] In the embodiment of the present application, the signal processing unit 60 is electrically connected to the first detection grating 40 and the second detection grating 50, and the controller 70 is electrically connected to the signal processing unit 60 and the clamping motor 300. When the controller 70 receives the first detection signal and / or the second detection signal, it controls the clamping motor 300 to start and stop, that is, the clamping motor 300 can stop driving the first clamp arm 100 and the second clamp arm 200 to continue clamping the steel coil 80, so that the first clamp arm 100 and the second clamp arm 200 can maintain a safe distance from the steel coil 80. In the embodiment of the present application, the model that can be selected for the signal processing unit 60 is FX-n18p.

[0057] Alternatively, the clamping motor 300 can drive the first clamp arm 100 and the second clamp arm 200 to open, so that the distance between the first clamp arm 100 and the second clamp arm 200 and the edge of the steel coil 80 can be adjusted to keep a safe distance between the first clamp arm 100 and the second clamp arm 200 and the steel coil 80. In the embodiment of the present application, the first detection grating 40 and the second detection grating 50 can be a high temperature resistant type, model FX-520O+SP-885CS, which can adapt to the 700°C high temperature environment of the steel coil 80.

[0058] In the embodiment of the present application, the first safety detection distance D1 and the second safety detection distance D2 can be maintained within a range greater than 10 mm and less than 20 mm. Figure 1 As shown, in actual applications, when the distance between the right side of the steel coil 80 and the first clamp arm 100 is 10 mm, the first detection grating 40 is triggered by the right side of the steel coil 80 and generates a first detection signal, and the signal processing unit 60 processes and sends the first detection signal to the controller 70. The controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 cannot continue to drive the first clamp arm 100 to continue to move toward the right side of the steel coil 80, thereby maintaining a safe distance (i.e., greater than 10 mm) between the first clamp arm 100 and the right side of the steel coil 80.

[0059] Moreover, when the distance between the right side of the steel coil 80 and the first clamp arm 100 is 20 mm, the first detection grating 40 is triggered by the right side of the steel coil 80 and generates a first detection signal. The signal processing unit 60 processes and sends the first detection signal to the controller 70. The controller 70 can control the clamping motor 300 to be in the starting state in real time, so that the clamping motor 300 can continue to drive the first clamp arm 100 to continue to move toward the right side of the steel coil 80 to adjust the distance between the first clamp arm 100 and the right side of the steel coil 80, so that the first clamp arm 100 can maintain a safe distance (i.e. less than 20 mm) from the right side of the steel coil 80.

[0060] For example, Figure 1 As shown, in actual applications, when the distance between the left side of the steel coil 80 and the second clamp arm 200 is 10 mm, the second detection grating 50 is triggered by the left side of the steel coil 80 and generates a second detection signal, and the signal processing unit 60 processes and sends the second detection signal to the controller 70. The controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 cannot continue to drive the second clamp arm 200 to move toward the right side of the steel coil 80, thereby keeping the second clamp arm 200 and the left side of the steel coil 80 at a safe distance (i.e. greater than 10 mm).

[0061] Moreover, when the distance between the left side of the steel coil 80 and the second clamp arm 200 is 20 mm, the second detection grating 50 is triggered by the left side of the steel coil 80 and generates a second detection signal. The signal processing unit 60 processes and sends the second detection signal to the controller 70. The controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 can continue to drive the second clamp arm 200 to continue moving toward the right side of the steel coil 80 to adjust the distance between the second clamp arm 200 and the left side of the steel coil 80, so that the second clamp arm 200 can maintain a safe distance (i.e. less than 20 mm) from the left side of the steel coil 80.

[0062] It should be noted that in actual applications, the first clamp arm 100 and the second clamp arm 200 can be opened or closed at the same time, the first detection signal and the second detection signal can be generated at the same time, and the first clamp arm 100 and the second clamp arm 200 can move toward and clamp the steel coil 80 at the same time, so that the first clamp foot 102 and the second clamp foot 202 can move toward the steel coil 80 at the same time and evenly hook the inner sides of the two ends of the steel coil 80, so that the steel coil 80 can be lifted smoothly.

[0063] The steel coil clamp edge damage prevention detection device provided in the embodiment of the present application, when the edge of the steel coil 80 triggers the first detection grating 40 or the second detection grating 50 during the process of the first clamp arm 100 and the second clamp arm 200 clamping the steel coil 80, the clamping motor 300 can be controlled to be in a stopped state through the controller 70 to prevent the edge of the steel coil 80 from continuing to approach the lining plate, thereby preventing direct collision and friction between the edge of the steel coil 80 and the lining plate, and can effectively solve the problem that the steel coil 80 is easily damaged during the lifting process.

[0064] like Figure 1 and 2 As shown, in some embodiments, the first clamp arm 100 includes a first lining plate 101, and the first detection grating 40 is arranged in front of the first lining plate 101. The second clamp arm 200 includes a second lining plate 201, and the second detection grating 50 is arranged in front of the second lining plate 201. By respectively arranging the first detection grating 40 and the second detection grating 50 in front of the first lining plate 101 and the second lining plate 201, the safety distance between the right and left parts of the steel coil 80 and the first lining plate 101 and the second lining plate 201 can be detected simultaneously.

[0065] like Figure 1 As shown, in actual application scenarios, when the distance D1 between the right side of the steel coil 80 and the first lining plate 101 is 10 mm, the first detection grating 40 is triggered by the right side of the steel coil 80 and generates a first detection signal, and the signal processing unit 60 processes and sends the first detection signal to the controller 70, and the controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 cannot continue to drive the first lining plate 101 to continue to move toward the right side of the steel coil 80, so that the first lining plate 101 can maintain a safe distance (i.e., greater than 10 mm) from the right side of the steel coil 80;

[0066] Moreover, when the distance D1 between the right side of the steel coil 80 and the first lining plate 101 is 20 mm, the first detection grating 40 is triggered by the right side of the steel coil 80 and generates a first detection signal. The signal processing unit 60 processes and sends the first detection signal to the controller 70. The controller 70 can control the clamping motor 300 to be in the starting state in real time, so that the clamping motor 300 can continue to drive the first lining plate 101 to continue to move toward the right side of the steel coil 80 to adjust the distance between the first lining plate 101 and the right side of the steel coil 80, so that the first lining plate 101 can maintain a safe distance (i.e. less than 20 mm) from the right side of the steel coil 80.

[0067] like Figure 1 As shown, in actual application scenarios, when the distance D2 between the left side of the steel coil 80 and the second lining plate 201 is 10 mm, the second detection grating 50 is triggered by the left side of the steel coil 80 and generates a second detection signal, and the signal processing unit 60 processes and sends the second detection signal to the controller 70, and the controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 cannot continue to drive the second lining plate 201 to move toward the right side of the steel coil 80, so that the second lining plate 201 can maintain a safe distance (i.e., greater than 10 mm) from the left side of the steel coil 80;

[0068] Moreover, when the distance D2 between the left side of the steel coil 80 and the second lining plate 201 is 20 mm, the second detection grating 50 is triggered by the left side of the steel coil 80 and generates a second detection signal. The signal processing unit 60 processes and sends the second detection signal to the controller 70. The controller 70 can control the clamping motor 300 to be in the starting state in real time. The clamping motor 300 can continue to drive the second lining plate 201 to continue to move toward the right side of the steel coil 80 to adjust the distance between the second lining plate 201 and the left side of the steel coil 80, so that the second lining plate 201 and the left side of the steel coil 80 can be kept at a safe distance (i.e. less than 20 mm).

[0069] like Figure 1 As shown, in some embodiments, the first detection grating 40 includes a first transmitting end 401 and a first receiving end 402, and the first transmitting end 401 and the first receiving end 402 are respectively arranged on both sides in front of the first lining plate 101. In other embodiments, the second detection grating 50 includes a second transmitting end 501 and a second receiving end 502, and the second transmitting end 501 and the second receiving end 502 are respectively arranged on both sides in front of the second lining plate 201. By arranging the first transmitting end 401 and the first receiving end 402 on both sides in front of the first lining plate 101, and arranging the second transmitting end 501 and the second receiving end 502 on both sides in front of the second lining plate 201, a detection area can be formed in front of the first lining plate 101 and the second lining plate 201, so as to ensure the detection of the distance between the edge of the steel coil 80 and the first lining plate 101 and the second lining plate 201.

[0070] like Figure 1 As shown, in some embodiments, when the distance between the right side of the steel coil 80 and the first lining plate 101 is the first safety detection distance D1, the first transmitting end 401 and the first receiving end 402 are triggered by the right side of the steel coil 80 and generate a first detection signal. Figure 1 As shown, in actual applications, when the distance D1 between the right side of the steel coil 80 and the first lining plate 101 is 10 mm, the first transmitting end 401 and the first receiving end 402 are triggered by the right side of the steel coil 80 and generate a first detection signal, and the controller 70 can control the clamping motor 300 to be in a stopped state in real time, so that the first lining plate 101 and the right side of the steel coil 80 can be kept at a safe distance (i.e. greater than 10 mm).

[0071] Moreover, when the distance D1 between the right side of the steel coil 80 and the first lining plate 101 is 20 mm, the first transmitting end 401 and the first receiving end 402 are triggered by the right side of the steel coil 80 and generate a first detection signal, and the controller 70 can control the clamping motor 300 to be in the starting state in real time, so that the clamping motor 300 can continue to drive the first lining plate 101 to continue to move toward the right side of the steel coil 80 to adjust the distance between the first lining plate 101 and the right side of the steel coil 80, so that the first lining plate 101 and the right side of the steel coil 80 can be maintained at a safe distance (i.e. less than 20 mm).

[0072] like Figure 1 As shown, in some embodiments, when the distance between the left side of the steel coil 80 and the second lining plate 201 is the second safety detection distance D2, the second transmitting end 501 and the second receiving end 502 are triggered by the left side of the steel coil 80 and generate a second detection signal. Figure 1 As shown, in actual application scenarios, when the distance D2 between the left side of the steel coil 80 and the second lining plate 201 is 10 mm, the second transmitting end 501 and the second receiving end 502 are triggered by the left side of the steel coil and generate a second detection signal, and the controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 cannot continue to drive the second lining plate 201 to move toward the left side of the steel coil 80, so that a safe distance (i.e., greater than 10 mm) can be maintained between the second lining plate 201 and the left side of the steel coil 80; and When the distance D2 between the edge and the second lining plate 201 is 20 mm, the second transmitting end 501 and the second receiving end 502 are triggered by the left side of the steel coil 80 and generate a second detection signal. The controller 70 can control the clamping motor 300 to be in the starting state in real time, and the clamping motor 300 can continue to drive the second lining plate 201 to continue to move toward the left side of the steel coil 80 to adjust the distance between the second lining plate 201 and the left side of the steel coil 80, so that the second lining plate 201 and the left side of the steel coil 80 can maintain a safe distance (i.e. less than 20 mm).

[0073] like Figure 2 As shown, in some embodiments, the signal processing unit 60 includes a first fiber optic signal amplifier 601 and a second fiber optic signal amplifier 602, the first fiber optic signal amplifier 601 and the second fiber optic signal amplifier 602 are respectively connected to the first detection grating 40 and the second detection grating 50, the output ends of the first fiber optic signal amplifier 601 and the second fiber optic signal amplifier 602 are respectively connected to the input end of the controller 70, and the first fiber optic signal amplifier 601 and the second fiber optic signal amplifier 602 are respectively used to receive and amplify the first detection signal and the second detection signal. The first fiber optic signal amplifier 601 and the second fiber optic signal amplifier 602 can transmit stable and reliable first detection signals and second detection signals to the controller 70, respectively, which can effectively prevent electromagnetic interference, so that the controller 70 can control the clamping motor 300 more accurately.

[0074] In another aspect of the embodiment of the present application, a detection method of the steel coil clamp edge damage prevention detection device based on the above embodiment is provided, and the detection method comprises the following steps:

[0075] Step 1: Acquire and process the first detection signal and the second detection signal in real time;

[0076] Step 2: When the first detection signal or the second detection signal is received, the clamping motor 300 is controlled to stop driving the first clamp arm 100 and the second clamp arm 200 .

[0077] By detecting the distance between the right side of the steel coil 80 and the first lining plate 101 through the first detection grating 40 and controlling the clamping motor 300 to stop in real time through the controller 70, a safe distance can be maintained between the right side of the steel coil 80 and the first lining plate 101. In the embodiment of the present application, the safe distance between the right side of the steel coil 80 and the first lining plate 101 can be maintained within a range greater than 10 mm and less than 20 mm.

[0078] like Figure 1 As shown, in an actual steel coil lifting scenario, when the distance D1 between the right side of the steel coil 80 and the first lining plate 101 is 10 mm, the first transmitting end 401 and the first receiving end 402 are triggered by the right side of the steel coil 80 and generate a first detection signal, and the controller 70 can control the clamping motor 300 to be in a stopped state in real time, so that the first lining plate 101 and the right side of the steel coil 80 can be maintained at a safe distance (i.e., greater than 10 mm).

[0079] Moreover, when the distance D1 between the right side of the steel coil 80 and the first lining plate 101 is 20 mm, the first transmitting end 401 and the first receiving end 402 are triggered by the right side of the steel coil 80 and generate a first detection signal, and the controller 70 can control the clamping motor 300 to be in the starting state in real time, so that the clamping motor 300 can continue to drive the first lining plate 101 to continue to move toward the right side of the steel coil 80 to adjust the distance between the first lining plate 101 and the right side of the steel coil 80, so that the first lining plate 101 and the right side of the steel coil 80 can be maintained at a safe distance (i.e. less than 20 mm).

[0080] The second detection grating 50 detects the distance between the left side of the steel coil 80 and the second lining plate 201, and the controller 70 controls the clamping motor 300 to stop in real time, so that the left side of the steel coil 80 and the second lining plate 201 can be kept at a safe distance. In the embodiment of the present application, the safe distance between the left side of the steel coil 80 and the second lining plate 201 can be kept within a range greater than 10 mm and less than 20 mm.

[0081] like Figure 1 As shown, in the actual steel coil lifting scenario, when the distance D2 between the left side of the steel coil 80 and the second lining plate 201 is 10 mm, the second transmitting end 501 and the second receiving end 502 are triggered by the left side of the steel coil 80 and generate a second detection signal, and the controller 70 can control the clamping motor 300 to be in a stopped state in real time, and the clamping motor 300 cannot continue to drive the second lining plate 201 to move toward the left side of the steel coil 80, so that the second lining plate 201 can maintain a safe distance (i.e., greater than 10 mm) from the left side of the steel coil 80.

[0082] Moreover, when the distance D2 between the left side of the steel coil 80 and the second lining plate 201 is 20 mm, the second transmitting end 501 and the second receiving end 502 are triggered by the left side of the steel coil 80 and generate a second detection signal, and the controller 70 can control the clamping motor 300 to be in the starting state in real time, and the clamping motor 300 can continue to drive the second lining plate 201 to continue to move toward the left side of the steel coil 80 to adjust the distance between the second lining plate 201 and the left side of the steel coil 80, so that the second lining plate 201 and the left side of the steel coil 80 can be maintained at a safe distance (i.e. less than 20 mm).

[0083] In some embodiments, the detection method comprises the following steps:

[0084] If the first detection signal or the second detection signal is not received, the controller 70 controls the clamping motor 300 to be in the starting state.

[0085] For example, in actual applications, when the distance between the right side of the steel coil 80 and the first lining plate 101 is maintained in a range greater than 10 mm and less than 20 mm, the first transmitting end 401 and the first receiving end 402 are not triggered by the right side of the steel coil 80, and the controller 70 can control the clamping motor 300 to be in a started state in real time; that is, the controller 70 controls the clamping motor 300 in real time to drive the first clamp arm 100 to continue to maintain the clamping state on the right side of the steel coil 80, thereby ensuring the stability and safety of the steel coil 80 during the lifting process.

[0086] The detection method of the steel coil clamp edge damage prevention detection device provided in the embodiment of the present application based on the aforementioned embodiment can realize non-contact detection of the distance between the first lining plate 101 and the second lining plate 201 and the right side of the steel coil 80 and the left side of the steel coil 80 respectively, which can prevent edge damage of the steel coil 80 and effectively improve the safety and efficiency of the lifting operation of the steel coil 80.

[0087] What is described above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any variation, modification or equivalent substitution made by those skilled in the art without departing from the technical concept of the present application, and all embodiments obtained, shall fall within the scope of protection of the claims of the present application.
