[0028] Furthermore, an arc groove is provided at the top of the loading plate 317, and there are two fixing rods 319. The fixing rods 319 are distributed on the left and right sides of the loading car 312 in a left-right symmetrical structure. The steel coil can be placed in a close fit through the arc groove, thereby improving the stability of the steel coil on the loading plate 317. The left and right holes of the steel coil can be inserted and fixed by the fixing rods 319 on the left and right sides, thereby further improving the transportation stability of the steel coil.

[0029] Furthermore, a slope is provided at the bottom end of the fixing rod 319, and the outer wall of the fixing rod 319 fits closely with the inner wall of the sliding hole provided on the outer wall of the loading trolley 312. Through the provided slope, the fixing rod 319 can be squeezed when the loading plate 317 moves downward, so that the fixing rod 319 can pass over the loading plate 317 and fit into its outer wall, so as to facilitate the fixing of the steel coil for the next loading.

[0030] Furthermore, there are two hydraulic cylinders 3110, which are symmetrically distributed on the left and right sides of the bottom end of the loading trolley 312. The inner wall of the slide rail 311 fits snugly with the outer wall of the roller of the loading trolley 312, so that the left and right sides of the loading trolley 312 can be supported simultaneously, thereby improving the stability of the loading trolley 312 during the up and down movement. At the same time, the roller and the inner wall of the slide rail 311 fit snugly with each other, which can ensure the stability of the loading trolley 312 during the movement.

[0031] The moving mechanism 32 includes a fixed plate 321 fixedly connected to the bottom end of the loading trolley 312, the outer wall of the fixed plate 321 is fixedly connected to a motor 322, the output end of the motor 322 is fixedly connected to a rotating rod 323, the end of the rotating rod 323 away from the motor 322 is fixedly connected to a gear 324, and the top of the base 1 is fixedly connected to a tooth block 325, and the gear 324 is meshed with the tooth block 325.

[0032] Furthermore, there are several tooth blocks 325, which are evenly and equidistantly distributed on the top of the base 1, so that when the gear 324 rotates, it can move forward or backward along the direction of the tooth block 325, thereby driving the loading car 312 to move left and right.

[0033] The implementation principle of a pickling workshop loading and uncoiling system of the present embodiment is as follows: the steel coil can be supported and moved by the loading trolley 312, and the loading trolley 312 can be limited and moved by the slide rail 311, and the steel coil is placed on the loading plate 317. The weight of the steel coil will drive the loading plate 317 to move downward. When the loading plate 317 moves downward, it can drive the supporting slide bar 316 to move downward on the inner wall of the sliding sleeve 314. In the process of the supporting slide bar 316 moving downward, the first spring 315 can be squeezed and compressed. At this time, the loading plate 317, which is attached to the outer walls on the left and right sides thereof, will be separated from the limiting effect of the attachment thereto when moving downward, so that the second spring 318 can rebound and reset, and then pull the fixing rod 319 to move to the middle position, and then insert the fixing rod 319 into the center hole of the steel coil, so that the The steel coil is limited and fixed. When the loading trolley 312 moves to the position of the uncoiler 2, the hydraulic cylinder 3110 is started, and its output end will extend downward and then lift the loading trolley 312 until the central hole of the steel coil is moved to a position parallel to the uncoiler 2. The loading trolley 312 is then moved to continue moving, and the steel coil is inserted into the uncoiler 2. The inner wall of the steel coil is supported and fixed by the uncoiler 2. The hydraulic cylinder 3110 is then started to retract, driving the loading trolley 312 to reset. In the process of moving downward, the inclined surface at the bottom end of the fixing rod 319 will be squeezed by the top of the loading plate 317, thereby moving to the left and right sides until the outer wall of the loading plate 317 is again fitted and limited to the outer wall of the fixing rod 319. In this way, the steel coil can be fixed and limited to prevent the steel coil from falling onto the loading trolley 312 during transportation and loading, causing a safety hazard.

[0034] When the steel coil is loaded, the motor 322 can be started, and its output end will drive the rotating rod 323 to rotate. When the rotating rod 323 rotates, it can drive the gear 324 to rotate. When the gear 324 rotates, it can mesh and rotate with the tooth block 325, thereby moving along the direction of the tooth block 325, which can drive the loading car 312 to move, so that the movement and loading can be completed without human intervention in the whole process.
