[0061] The control device 9 is electrically connected to the starting device 6, the first measuring device 7, the second measuring device 8, the lifting mechanism, the moving mechanism and the cutting gun 32. The control device 9 is used to control the moving mechanism to drive the cutting gun 32 to move to the initial position according to the starting instruction. After the cutting gun 32 moves to the initial position, the control device 9 calculates the distance between the initial position and the upper surface of the steel coil 5 to be cut according to the distance between the first measuring device 7 and the upper surface of the steel coil 5 to be cut, and controls the lifting mechanism to drive the cutting gun 32 to move according to the calculated distance. When the cutting gun 32 moves to the upper surface of the steel coil 5 to be cut, the control device 9 controls the moving mechanism to drive the cutting gun 32 to move to the upper edge of the steel coil 5 to be cut according to the distance between the cutting gun 32 and the upper edge of the steel coil 5 to be cut. Then, the control device 9 controls the cutting gun 32 to cut the steel coil 5 to be cut.

[0062] In specific implementation, the control device 9 pre-stores a cutting speed that matches the diameter of the steel coil 5 to be cut.

[0063] When the cutting gun 32 starts cutting, the control device 9 controls the lifting mechanism to drive the cutting gun 32 to move according to the pre-stored cutting speed matching the steel coil 5 to be cut. When the cutting gun 32 cuts to the preset height from the rotating platform 1, the steel coil 5 to be cut is not completely cut, and then the lifting mechanism is controlled to return to the upper edge of the steel coil 5 to be cut. The rotating platform 1 drives the steel coil 5 to be cut to rotate 90°, and the above operation is repeated to cut the steel coil 5 to be cut, and then the rotating platform 1 is rotated to cut again, until the four directions of the steel coil 5 to be cut are all cut, and the rotating platform 1 is rotated to the starting position again.

[0064] The control device 9 controls the lifting mechanism to drive the cutting gun 32 to move, and the cutting gun 32 completely cuts off the remaining parts of the previous cutting, and then controls the lifting mechanism to return to the upper edge of the steel coil 5 to be cut. The rotating platform 1 drives the steel coil 5 to be cut to rotate 90°, repeats the above operation to cut the steel coil 5 to be cut, and then rotates the rotating platform 1 to cut again, until all four directions of the steel coil 5 to be cut are completely cut. The control device 9 controls the lifting mechanism to drive the cutting gun 32 back to the initial position.

[0065] The control device 9 is electrically connected to the walking device 2. The control device 9 controls the walking device 2 to move to another rotating platform 1 and repeats the above operation. In this way, the steel coils 5 to be cut on the two rotating platforms 1 are cut alternately, thereby realizing double-station cutting of the steel coils.

[0066] Specifically, the control device 9 is electrically connected to the lifting motor 33 in the lifting mechanism, the moving motor 37 in the moving mechanism and the traveling motor 24 in the traveling device 2, and the control device 9 controls the movements of each structure by controlling the motors.

[0067] It can be seen that in this embodiment, the cutting device 3 is controlled by the control device 9 to cut the steel coil, and no manual operation is required, thereby achieving automatic and precise control. In addition, the position of the cutting gun 32 can be adjusted according to the diameter of the steel coil 5 to be cut, so that the cutting gun 32 can accurately cut the steel coil 5 to be cut.

[0069] Method Example:

[0070] This embodiment also proposes a cutting control method for a steel coil double-station cutting device, wherein the steel coil double-station cutting device is a method for cutting control using the steel coil double-station cutting device in the above device embodiment. Fig.11 , the cutting control method of the steel coil double-station cutting device comprises the following steps;

[0071] In the placing step S1, a steel coil to be cut is placed on a first rotating platform, and another steel coil to be cut is placed on a second rotating platform.

[0072] Specifically, see Figures 1 to 3 , a steel coil 5 to be cut is placed on each of the two rotating platforms 1. More specifically, the two steel coils 5 to be cut are hoisted onto the two rotating platforms 1 by a crane, and the placement positions of the steel coils 5 to be cut are adjusted by the crane. At this time, the traveling device 2 is not moving.

[0073] The first moving step S2 is to control the walking device to move to the first rotating platform.

[0074] Specifically, see Figures 1 to 9 The control device 9 is electrically connected to the travel motor 24 in the travel device 2. The control device 9 controls the travel motor 24 to drive the wheel 25 to move along the travel track 11 to the first rotating platform 1, thereby driving the cutting device 3 and the dust removal device 4 to move along the travel track 11 to the first rotating platform 1.

[0075] In the cutting step S3, the cutting device is controlled to cut the steel coil to be cut, and the dust removal device is controlled to collect and purify the dust generated by the cutting.

[0076] Specifically, the control device 9 is electrically connected to the cutting device 3 and the dust removal device 4. The control device 9 controls the cutting device 3 to cut the steel coil 5 to be cut, and the dust removal device 4 collects and purifies the dust generated during cutting.

[0077] In the second moving step S4, after the cutting is completed, the steel coil that has been cut on the first rotating platform is lifted and a new steel coil to be cut is placed, and at the same time, the walking device is controlled to move to the second rotating platform and the cutting step is repeated. The steel coils to be cut on the two rotating platforms are cut alternately.

[0078] Specifically, when the steel coil 5 to be cut on the first rotating platform 1 is cut, the cut steel coil is lifted and recovered, and then a new steel coil 5 to be cut is placed on the first rotating platform 1. At the same time, the control device 9 controls the travel motor 24 to drive the wheels 25 to move along the travel track 11 to the second rotating platform 1, and the control device 9 controls the cutting device 3 to cut the steel coil 5 to be cut, and controls the dust removal device 4 to collect and purify the dust generated by the cutting. When the steel coil 5 to be cut on the second rotating platform 1 is cut, the cut steel coil is lifted and recovered, and then a new steel coil 5 to be cut is placed on the second rotating platform 1. At the same time, the control device 9 controls the travel motor 24 to drive the wheels 25 to move along the travel track 11 to the first rotating platform 1, and repeats the above operations to alternately cut the steel coils 5 to be cut on the two rotating platforms 1.

[0079] In the above steps, the specific implementation process of the steel coil double-station cutting device can be found in the above description, and this embodiment will not be repeated here.

[0080] It can be seen that in this embodiment, the walking device is first controlled to walk to the first rotating platform, and then the cutting device is controlled to cut the steel coil to be cut, and the dust removal device is controlled to collect and purify the dust generated by the cutting; after the cutting is completed, the steel coil cut on the first rotating platform is lifted, and a new steel coil to be cut is placed, and at the same time, the walking device is controlled to walk to the second rotating platform, and the above operation is repeated, so as to alternately cut the steel coils to be cut on the two rotating platforms. In this way, there is no need for manual cutting, which reduces the harm to the staff during the cutting process, reduces the risk of injury to the staff, and can effectively improve the cutting speed. In addition, the steel coils to be cut on the two rotating platforms are alternately cut, realizing double-station cutting, which effectively improves the cutting efficiency.

[0081] See also Figures 1 to 6The cutting device 3 includes: a main body 31, a lifting mechanism, a moving mechanism and a cutting gun 32; wherein the lifting mechanism is arranged on the main body 31 and connected to the cutting gun 32, and the lifting mechanism is used to drive the cutting gun 32 to move up and down. The moving mechanism is arranged on the main body 31 and connected to the traveling device 2, and the moving mechanism is used to drive the main body 31 to move laterally along the traveling device 2, so that the cutting gun 32 is close to the steel coil 5 to be cut. The control device 9 is electrically connected to the lifting mechanism, the moving mechanism and the cutting gun 32, so that the control device 9 can control their respective operations.

[0082] The cutting step S3 further comprises:

[0083] The first moving sub-step S31 is to control the moving mechanism to drive the cutting gun to move to an initial position.

[0084] Specifically, see Fig.10 The control device 9 is electrically connected to the starting device 6 and the moving motor 35 in the moving mechanism. The starting device 6 is used to input a starting instruction. The control device 9 controls the moving motor 35 to move along the moving track according to the starting instruction, thereby driving the cutting gun 32 to move to the initial position along the moving track, that is, to move to the initial position along the lateral direction of the walking device 2. When the cutting gun 32 reaches the initial position, the control device 9 stops driving, that is, the cutting gun 32 stops moving.

[0085] The second moving sub-step S32 measures the distance between the top of the walking device and the upper surface of the steel coil to be cut, and calculates the distance between the initial position and the upper surface of the steel coil to be cut, and controls the lifting mechanism according to the calculated distance to drive the cutting gun to move to the upper surface of the steel coil to be cut.

[0086] Specifically, the first measuring device 7 measures the distance between itself and the upper surface of the steel coil to be cut. The control device 9 is electrically connected to the first measuring device 7 and the lifting motor 33 in the lifting mechanism. The control device 9 calculates the distance between the initial position of the cutting gun 32 and the upper surface of the steel coil to be cut according to the measured distance. The calculated distance is the distance that the telescopic arm 34 is extended. The control device 9 controls the lifting motor 33 to drive the telescopic arm 34 to extend according to the calculated distance, and drives the cutting gun 32 to move downward until the cutting gun 32 moves to the upper surface of the steel coil to be cut, and the cutting gun 32 stops moving.

[0087] The third moving sub-step S33 measures the distance between the cutting gun and the upper edge of the steel coil to be cut, and controls the moving mechanism to drive the cutting gun to move to the upper edge of the steel coil to be cut according to the distance.

[0088] Specifically, the second measuring device 8 measures the distance between the cutting gun 32 and the upper edge of the steel coil 5 to be cut. The control device 9 is electrically connected to the second measuring device 8. The control device 9 controls the moving motor 35 to move along the moving track according to the measured distance, thereby driving the cutting gun 32 to move along the moving track until the cutting gun 32 reaches the upper edge of the steel coil to be cut and stops moving.

[0089] In the first cutting sub-step S34, the cutting gun is controlled to cut the steel coil to be cut at a preset cutting speed, and when the cutting reaches a preset height from the rotating platform, the lifting mechanism is controlled to drive the cutting gun to move to the upper edge of the steel coil to be cut.

[0090] Specifically, the control device 9 is electrically connected to the cutting gun 32. When the control device 9 controls the cutting gun 32 to start cutting, the combustion medium is first ejected through the cutting gun 32 and starts to ignite and burn, preheating the edge of the steel coil, and then the cutting gun 32 starts cutting.

[0091] The control device 9 pre-stores a cutting speed that matches the diameter of the steel coil 5 to be cut. During cutting, the control device 9 controls the lifting motor 33 to drive the telescopic arm 34 to extend according to the pre-stored cutting speed that matches the steel coil 5 to be cut, and drives the cutting gun 32 to move downward. When the cutting gun 32 cuts to a preset height from the rotating platform 1, the steel coil 5 to be cut is not completely cut at this time, and then the control device 9 controls the lifting motor 33 to drive the telescopic arm 34 to retract, and the telescopic arm 34 drives the cutting gun 32 to retract to the upper edge of the steel coil 5 to be cut.

[0092] The first rotation sub-step S35 is to control the rotating platform to drive the steel coil to be cut to rotate 90°, and repeat the first cutting sub-step S34.

[0093] Specifically, the control device 9 is electrically connected to the driving motor at the rotating platform 1. The control device 9 controls the rotating platform 1 to drive the steel coil 5 to be cut to rotate 90°, and then controls the cutting gun 32 to cut the steel coil 5 to be cut to a preset height from the rotating platform 1, and then controls the lifting motor 33 to drive the telescopic arm 34 to retract, and the telescopic arm 34 drives the cutting gun 32 to retract to the upper edge of the steel coil 5 to be cut.

[0094] In the first cyclic cutting sub-step S36, the first rotating sub-step S35 is repeated to cut the steel coil in four directions, and the rotating platform is controlled to rotate to the starting position.

[0095] Specifically, the control device 9 controls the rotating platform 1 again to drive the steel coil 5 to be cut to rotate 90°, the cutting gun 32 cuts the steel coil 5 to be cut to a preset height from the rotating platform 1, and the telescopic arm 34 drives the cutting gun 32 to retract to the upper edge of the steel coil 5 to be cut. This operation is repeated until the steel coil 5 to be cut is cut from four directions to a preset height from the rotating platform 1, and the rotating platform 1 is controlled to rotate to the starting position again.

[0096] The second cutting sub-step S37 is to control the lifting mechanism to drive the cutting gun to move toward the steel coil to be cut, completely cut the steel coil to be cut, and then control the lifting mechanism to drive the cutting gun to move to the upper edge of the steel coil.

[0097] Specifically, the control device 9 controls the lifting motor 33 to drive the telescopic arm 34 to extend, and the telescopic arm 34 drives the cutting gun 32 to move downward, and the cutting gun 32 completely cuts the steel coil 5 to be cut. Then, the control device 9 controls the lifting motor 33 to drive the telescopic arm 34 to retract, and the telescopic arm 34 drives the cutting gun 32 to move upward to the upper edge of the steel coil 5 to be cut.

[0098] The second rotation sub-step S38 is to control the rotating platform to drive the steel coil to be cut to rotate 90°, and repeat the second cutting sub-step S37.

[0099] Specifically, the control device 9 controls the rotating platform 1 to drive the steel coil 5 to be cut to rotate 90°, then controls the cutting gun 32 to completely cut the steel coil 5 to be cut, and then controls the lifting motor 33 to drive the telescopic arm 34 to retract, and the telescopic arm 34 drives the cutting gun 32 to move upward to the upper edge of the steel coil 5 to be cut.

[0100] The second cyclic cutting sub-step S39 repeats the second rotation sub-step S38 until all the steel coils to be cut are completely cut, and the moving mechanism and the lifting mechanism are controlled to drive the cutting gun back to the initial position.

[0101] Specifically, the control device 9 controls the rotating platform 1 again to drive the steel coil 5 to be cut to rotate 90°, the cutting gun 32 completely cuts the steel coil 5 to be cut, and the telescopic arm 34 drives the cutting gun 32 to move upward to the upper edge of the steel coil 5 to be cut, and repeats this operation until the steel coil 5 to be cut is completely cut from all four directions, and controls the rotating platform 1 to rotate to the starting position again. Then, the control device 9 controls the lifting motor 33 to drive the telescopic arm 34 to retract, and the telescopic arm 34 drives the cutting gun 32 back to the initial position, and controls the moving motor 35 to drive the moving wheel 36 to move to the initial position along the moving track.

[0102] In summary, in this embodiment, the walking device is first controlled to move to the first rotating platform, and then the cutting device is controlled to cut the steel coil to be cut, and the dust removal device is controlled to collect and purify the dust generated by the cutting; after the cutting is completed, the steel coil cut on the first rotating platform is lifted, and a new steel coil to be cut is placed, and at the same time, the walking device is controlled to move to the second rotating platform, and the above operations are repeated, so as to alternately cut the steel coils to be cut on the two rotating platforms. In this way, there is no need for manual cutting, which reduces the harm to the staff during the cutting process, reduces the risk of injury to the staff, and can effectively improve the cutting speed. In addition, the steel coils to be cut on the two rotating platforms are alternately cut, realizing double-station cutting, which effectively improves the cutting efficiency.
