Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0031] The core of the present application is to provide a hook automatic detection system, which can determine the position of the hook 14 and the ladle without personnel on the pouring platform, and determine whether the hook 14 is separated from the ladle, and automatically complete the crane hook confirmation, realizing the unmanned and automation of the hook detection.
[0032] Please refer to Figure 1 and Figure 2 , a hook automatic detection system includes a control device, a ladle transfer device 1, a weighing device 2 and a detection device 3.
[0033] Specifically, the ladle transfer device 1 is connected with the control device, the ladle transfer device 1 is movably arranged on the pouring platform and is used for transferring the ladle and unhooking, the ladle is transferred through the movable arrangement of the ladle transfer device 1, the weighing device 2 is connected with the ladle transfer device 1, the weighing device 2 is used for weighing the weight of the ladle and sending to the control device, so that the control device obtains the signal of whether the ladle is transferred, the detection device 3 is fixed on the receiving steel side platform 4, the detection device 3 is used for detecting the position of the ladle and sending to the control device, the control device determines whether the ladle arrives from the ladle transfer position to the ladle seat position according to the detection device 3, the ladle transfer device 1 realizes the unhooking of the ladle through the cooperation of the detection device 3 and the control device, and the control device can accurately determine whether the unhooking is completed through the position of the ladle sent by the detection device 3.
[0034] The hook automatic detection system arranged in the above manner can automatically complete the unhooking confirmation in the unmanned condition, realize the unmanned and automation of the unhooking.
[0035] In the above embodiment, the ladle transfer device 1 includes a support 11, a rotary table 12 and a ladle arm 13, the support 11 is fixed on the pouring platform, the rotary table 12 is movably arranged on the support 11 and is rotatably connected with the support 11, and the ladle arm 13 is arranged in the circumferential direction of the rotary table 12 and is used for transferring the ladle.
[0036] It should be noted that the rotary table 12 rotates and lifts along the support 11 to move the ladle arm 13 between the receiving position and the casting position, when the ladle in the casting position is about to be poured, a full ladle will be hoisted to the receiving position in advance, and when the pouring is completed, the rotary table 12 will rotate the ladle to move the ladle in the receiving position to the casting position, and the empty ladle will be lifted away from the receiving position.
[0037] In the embodiment, the receiving position and the casting position are arranged at 180° along the circumference of the rotary table 12, but in actual life, the positions of the receiving position and the casting position are not limited as long as the above technical effects can be achieved.
[0038] In the above case, the ladle arm 13 is provided with at least two groups, and the at least two groups of ladle arms 13 are uniformly arranged along the circumference of the rotary table 12.
[0039] It can be understood that one group of ladle arms 13 corresponds to the receiving position, and the other group of ladle arms 13 corresponds to the casting position, and the two groups of ladle arms 13 enable the ladle to be used alternately in the receiving position and the casting position.
[0040] In the embodiment, the ladle arm 13 is provided with two groups, but in actual life, the number of groups of the ladle arm 13 is not limited as long as the above technical effects can be achieved.
[0041] Further, the ladle circulation device 1 further comprises a crown block, and the crown block is provided with a lifting hook 14, and the lifting hook 14 is used for transferring the ladle.
[0042] It should be noted that the ladle is transferred to the receiving position by the lifting hook 14 of the crown block, and the ladle is transferred after being positioned, at this time, the ladle arm 13 will be raised and rotated, and at this time, the unhooking needs to be completed to avoid the collision between the lifting hook 14 and the ladle arm 13.
[0043] In the above embodiment, the receiving side platform 4 is further provided with an automatic sensing indicator light, and the automatic sensing indicator light is used for sensing the position of the lifting hook 14.
[0044] It can be understood that whether the lifting hook 14 is unhooked or not is determined by the display state of the automatic sensing indicator light, so that the control device controls the next step, and the interference between the lifting hook 14 and the rotary table 12 is avoided.
[0045] On the basis of the above embodiment, the detection device 3 comprises a laser detection piece 31 and a visual detection piece 32, and the laser detection piece 31 and the visual detection piece 32 are fixed to the receiving side platform 4, the laser detection piece 31 is used for detecting the position of the ladle, and the visual detection piece 32 is used for detecting the position of the lifting hook 14 and the state of the automatic sensing indicator light.
[0046] It should be noted that the laser detection member 31 sends the arrival status of the ladle, and the visual detection member 32 detects the position of the hook 14 and sends a position signal to the control device to determine whether the hook 14 of the crane is separated from the ladle.
[0047] Further, before receiving the ladle, the ladle arm 13 of the receiving position of the rotary table 12 is weighed and displayed as 0. During the process that the hook 14 of the crane hoists the ladle onto the rotary table 12, the laser detection member 31 (the detection beam is upward) detects the cross arm of the hook 14 of the crane and is recorded. When the ladle is placed on the ladle arm 13 of the rotary table 12, the weighing device 2 generates a weighing data signal. When the hook 14 of the crane is withdrawn and separated from the ladle, it passes above the laser detection member 31 again and is recorded, and at the same time, the visual detection member 32 is triggered to start. The visual detection member 32 takes a photo in this area for detection in real time, and the program automatically determines whether the hook 14 of the ladle exists for secondary confirmation. If the hook 14 of the ladle is detected in this area, it can be determined that the hook 14 of the crane is separated from the rotary range of the ladle, and a prerequisite signal for the automatic ladle transfer control of the rotary table 12 can be obtained.
[0048] When the ladle is lifted, the ladle arm 13 of the receiving position of the rotary table 12 is weighed and displayed as the weight of the empty ladle. During the process that the hook 14 of the crane enters the rotary table 12, the laser detection member 31 (the detection beam is upward) detects the cross arm of the hook 14 of the crane and is recorded. When the ladle is lifted from the ladle arm 13 of the rotary table 12, the weighing device 2 generates a large change in the weighing data at this time and is recorded (from the weight of the empty ladle displayed as 0). When the hook 14 of the crane carries the ladle to withdraw, it passes above the laser detection member 31 again and is recorded, and at the same time, the visual detection member 32 is triggered to start. The visual detection member 32 takes a photo in this area for detection in real time, and the program automatically determines whether the hook 14 of the ladle exists for secondary confirmation. If the hook 14 of the crane is detected in this area, it can be determined that the hook 14 of the crane is separated from the rotary range of the ladle, and a prerequisite signal for the automatic ladle transfer control of the rotary table 12 can be obtained.
[0049] In summary, the hook automatic detection system provided by the present application is that the ladle arm 13 of the receiving steel side of the rotary table 12 is empty, the weighing device 2 sends the weight data to the control device, the ladle enters the lifting position, the laser detection member 31 sends the entering data of the ladle, the visual detection member 32 confirms whether the ladle has entered, the weighing device 2 sends the data to the control device after the ladle reaches the ladle seating position, and it is determined that the ladle is in place. After the ladle is in place, the control device receives the signal of the ladle in place sent by the weighing device 2, controls the hook 14 of the crane to be separated, and the hook 14 of the crane is withdrawn from the lifting position to the separation position. The visual detection member 32 detects the position of the hook 14 and sends it to the control device to determine whether the hook 14 of the crane is separated. Subsequently, the control device receives the signal of the position of the hook 14 sent by the laser detection member 31, and it is determined that the hook 14 of the crane is separated.
