The other end of the reciprocating screw rod A303 is fixed through the inner side of the extension frame A301 by the bearing A and is fixedly connected to the pulley A306. The surface thread sleeve of the reciprocating screw rod A303 is provided with a slider A304. The bottom of the slider A304 is fixedly installed with a photoelectric switch 305. The end of the stepping beam 1 is fixedly connected to the extension frame B307. The inner side of the extension frame B307 is rotatably connected to the reciprocating screw rod B308 through the bearing B. The other end of the reciprocating screw rod B308 is fixed through the bearing C and is fixedly connected to the inner side of the extension frame B307 and is fixedly connected to the pulley B3010. The pulley A306 is connected to the pulley B3010 through a belt drive, and a slider B3011 is provided on the surface of the reciprocating screw B308. A laser rangefinder 309 is fixedly connected to one side of the slider B3011. A strip hole is fixedly connected to the top of the top frame 2. The slider A304 contacts and slides with the hole wall of the strip hole. The bottom of the slider B3011 contacts and slides with the inner side of the extension frame B307. The strip hole is used to limit the slider B3011, so that the slider B3011 slides more stably on the inner wall of the strip hole. The laser rangefinder 309 is fixed to the side of the steel coil body 7. The photoelectric switch 305 is coordinated with the top of the steel coil body 7. The photoelectric switch 305 is set in coordination with the top of the steel coil body 7. When the steel coil body 7 passes the photoelectric switch, the diameter of the steel coil body 7 is measured. The distance that the unloading trolley 601 needs to travel is calculated by the data before and after the measurement, so as to ensure that it is placed in the middle position of the saddle 5 when it is transported to the first saddle 5. A frame roller 4 is set on the top of the walking beam 1, and the side of the frame roller 4 adjacent to the top frame 2 is the pause position. The unloading trolley 601 is programmed to calculate the stop position of the saddle 5 of the walking beam 1, that is, the center position of the steel coil body 7. The steel coil body 7 is allowed to land only when it reaches the center position of the saddle 5.

[0027] Furthermore, by adjusting the distance between the photoelectric switch 305 and the laser rangefinder 309, it is possible to detect whether the steel coil body 7 is in a horizontal state on the saddle 5. The laser rangefinder 309 and the photoelectric switch 305 can avoid deviation in the position of the steel coil body 7, so that the packaging is in the middle position of the steel coil body 7. The slow speed gear of the unloading trolley 601 is increased, and it is switched to the slowest speed before entering the saddle 5 to eliminate inertia deviation, extend the mechanical stroke of the unloading trolley 601 track and ensure that the track is level to meet the maximum offset adjustment amount in the direction of the stepping beam 1, increase the limit protection program of the unloading trolley 601, and manually block the photoelectric switch 305 signal and the laser rangefinder 309 when the outer ring is stretched and the roll is transported, causing a measurement width error.

[0028] Example 2

[0029] In this embodiment, an adjustment structure 6 is provided on the walking beam 1, and the adjustment structure 6 includes: an articulated frame 602, the bottom of the saddle 5 is hinged to the inner side of the articulated frame 602, the top of the unloading trolley 601 is fixedly connected to the cylinder 606, the inner wall of the cylinder 606 is movably connected to the movable rod 608, the other end of the movable rod 608 is fixedly connected to the articulated block B605, the bottom of the saddle 5 is fixedly connected to the articulated block A603, and the connecting rod 604 is articulated between the articulated block A603 and the articulated block B605. The roll body 7 is placed on the top of the saddle 5, and the top of the walking beam 1 is slidably connected to the roll unloading trolley 601. The bottom of the articulated frame 602 is fixedly connected to the top of the roll unloading trolley 601. The inner wall of the cylinder body 606 is fixedly connected with a spring 607. One end of the movable rod 608 is fixedly connected to the other end of the spring 607. The movable rod 608 contacts the inner wall of the cylinder body 606 and is slidably connected. Through the lateral elastic potential energy of the set spring 607, the movable rod 608 can be extended and retracted on the inner wall of the cylinder body 606.

[0030] Furthermore, after the saddle 5 is pressurized, the two ends of the connecting rod 604 are hinged and rotated, thereby driving the movable rod 608 to move inside the cylinder body 606, so that the movable rod 608 squeezes the spring 607. The saddle 5 that can adjust the position of the steel coil body 7 can improve the subsequent measurement accuracy by adjusting the position of the steel coil body 7, and can reduce the incidence of secondary defects in subsequent re-lifting.

[0031] Working principle: drive the unloading trolley 601 to move on the top of the stepping beam 1, and start the motor 302 so that the output shaft of the motor 302 drives the reciprocating screw A303 to rotate, and the rotating reciprocating screw A303 drives the slider A304 to move on the inner side of the extension frame, and the belt transmission between the pulley A306 and the pulley B3010 drives the reciprocating screw A303 to rotate in the same direction during the rotation, and the reciprocating screw B308 is used to rotate to drive the slider B3011 to move in the strip hole, thereby adjusting the distance between the photoelectric switch 305 and the laser rangefinder 309, and detecting whether the steel coil body 7 is in a horizontal state on the saddle 5. When the steel coil body 7 passes the photoelectric switch 305, the diameter of the steel coil body 7 is measured, and the unloading time is calculated based on the data before and after the measurement. The distance that the car 601 needs to travel is used to ensure that it is placed in the middle position of the saddle 5 when it is transported to the first saddle 5. At the same time, the rising and falling edges of the signal when the photoelectric switch 305 is blocked by the steel coil body 7 in transportation are used to record the real-time position data of the unloading trolley 601 and calculate the measured width of the steel coil body 7. The unloading trolley 601 is programmed to calculate the stop position of the saddle 5 of the stepping beam 1, that is, the center position of the steel coil body 7. The steel coil body 7 is allowed to land only when it reaches the center position of the saddle 5. When the saddle 5 is pressurized, the two ends of the connecting rod 604 are hinged and rotated, thereby driving the movable rod 608 to move on the inside of the cylinder 606, so that the movable rod 608 squeezes the spring 607. The saddle 5 that can adjust the position of the steel coil body 7 can improve the subsequent measurement accuracy by adjusting the position of the steel coil body 7, and can reduce the incidence of two defects caused by subsequent re-lifting.
