The extension or contraction of the first hydraulic rod 22 can drive the C-type hook 2 to rotate along the hook rotating shaft 21. When the plate rolling is hoisted, the contraction of the first hydraulic rod 22 drives the C-type hook 2 to rotate upward. At this time, the lower swing arm of the C-type hook 2 is tilted downward, and the opening of the lower swing arm of the C-type hook 2 is aligned with the plate rolling hole. The first hydraulic rod 22 is extended to drive the C-type hook 2 to rotate downward, so that the lower swing arm of the C-type hook 2 can be extended into the inside of the plate rolling hole. The other side of the hook connecting seat 1 is rotatably connected The second hydraulic column 24 is provided with a locking arm 3, and a side of the locking arm 3 close to the hook connecting seat 1 is provided with a second hydraulic column 24. The bottom of the second hydraulic column 24 is rotatably connected to the inner wall of the hook connecting seat 1 through a rotating shaft. The second hydraulic column 24 can drive the locking arm 3 to rotate along its top rotating shaft. The bottom of the telescopic arm 31 is fixedly connected with a locking protrusion 316, and the protruding part of the locking protrusion 316 is extended in the direction of the C-shaped hook 2. Before the lower swing arm of the C-shaped hook 2 extends into the hole of the rolling plate, the second hydraulic column 24 extends to drive the locking arm 3 to rotate upward along the top rotating shaft. Before the lower swing arm of the C-shaped hook 2 extends into the hole of the rolling plate and starts to lift the rolling plate, the second hydraulic column 24 contracts to cause the locking arm 3 to rotate downward and cause the locking protrusion 316 to extend into the hole on the other side of the rolling plate, thereby locking the rolling plate and improving the stability during the lifting process.

The lower end of the transmission chain 304 is fixedly connected with a connecting block 305. The connecting block 305 is fixedly connected to the telescopic arm 31 below it. The connecting block 305 is arranged at the right opening of the telescopic arm 31. The driving motor 301 drives the transmission chain 304 to rotate and then drives the telescopic arm 31 to slide along the inner wall of the locking arm 3, so as to control the extension or retraction of the telescopic arm 31. The extension length of the telescopic arm 31 can be adjusted according to different specifications of the rolling plate. By adjusting the extension length, the locking protrusion 316 can be extended into the hole on the other side of the rolling plate.

[0052] Please refer to Figure 7 The telescopic arm 31 includes a plurality of guide rails 311 and a stopper 313. The plurality of guide rails 311 are respectively fixedly connected to both sides of the telescopic arm 31.

The stopper 313 is fixedly connected to the opening of the telescopic arm 31. The stopper 313 is correspondingly arranged to a limit baffle 307 fixedly connected to the bottom opening of the locking arm 3. The stopper 313 and the limit baffle 307 cooperate with each other to prevent the telescopic arm 31 from being excessively extended.

[0053] like Figure 8As shown, the magnetic attraction component 32 includes an electromagnet 321, a connecting column 322, an abutment block 323 and a damping spring 324. The electromagnet 321 is arranged inside the locking arm 3, and one side of the electromagnet 321 is fixedly connected to the connecting column 322. One end of the connecting column 322 away from the electromagnet 321 penetrates to the outside of the locking arm 3, and the connecting column 322 is slidably connected to the side wall of the locking arm 3. The damping spring 324 is arranged on the outside of the locking arm 3 and is sleeved on the circumference of the connecting column 322. One end of the damping spring 324 abuts against the abutment block 323, and the abutment block 323 is fixedly connected to the circumference of the connecting column 322. The other end of the damping spring 324 abuts against the inner wall of the outer shell 325. One end of the outer shell 325 The end is fixedly connected to the outside of the locking arm 3, and a cast iron block 315 is arranged inside the telescopic arm 31. The cast iron block 315 is provided with two and both are fixedly connected to the inner wall of the telescopic arm 31 on the side close to the magnetic suction component 32. The cast iron block 315 is matched with the electromagnet 321. The electromagnet 321 can be magnetically attracted to the cast iron block 315. The electromagnet 321 is electrically connected to an external power supply. After power is turned on, it can be magnetically attracted to the cast iron block 315 to fix the telescopic arm 31. When the telescopic arm 31 locks the rolling plate, the telescopic arm 31 is locked by the electromagnet 321 to prevent the telescopic arm 31 from being pulled out by the rolling plate and losing the locking function. The strength of the telescopic arm 31 when locking the rolling plate is improved by the magnetic fixation of the electromagnet 321.

[0054] like Figure 5 and 7 As shown, the telescopic arm 31 also includes a first sliding groove 312 and a second sliding groove 314. The first sliding groove 312 is opened on one side of the telescopic arm 31. The first sliding groove 312 is matched with the middle rotating shaft of the driving gear 302 and the driven gear 303. The middle rotating shaft surface of the driving gear 302 and the driven gear 303 is slidably connected with the first sliding groove 312. The second sliding groove 314 is opened on the other side of the telescopic arm 31. The inner wall of the second sliding groove 314 is slidably connected with the connecting column 322.

[0055] A micro switch 23 is installed inside the hook connecting seat 1. The micro switch 23 is set on the right side of the hook rotating shaft 21. The micro switch 23 is used to control the angle of rotation of the C-type hook 2 driven by the first hydraulic rod 22. The optional model of the micro switch 23 is: KW12, or other micro switches that can achieve the same function. When the first hydraulic rod 22 extends to drive the lower swing arm of the C-type hook 2 to extend into the rolling plate hole, the C-type hook 2 will contact the contact of the micro switch 23 after rotating to a certain angle. At this time, the first hydraulic rod 22 stops extending and locks to prevent the C-type hook 2 from rotating too much, causing the front end of the lower swing arm of the C-type hook 2 to squeeze the inner wall of the rolling plate hole. The small contact point can easily cause damage to the rolling plate.

[0056] The principle of the present invention is as follows: the sling is installed on the lifting frame of the forklift through the lifting ear 421, the second hydraulic column 24 is extended to drive the locking arm 3 to rotate upward, the first hydraulic rod 22 is contracted to drive the C-type hook 2 to rotate upward, the forklift moves to align the lower swing arm of the C-type hook 2 with the hole of the roll plate, the first hydraulic rod 22 is extended to drive the C-type hook 2 to rotate downward, and the lower swing arm of the C-type hook 2 is extended into the hole of the roll plate, when the upper end of the C-type hook 2 contacts the side contact of the micro switch 23, the first hydraulic rod 22 stops extending and is locked, at this time The second hydraulic column 24 contracts and drives the locking arm 3 to rotate downward, and at the same time, the drive motor 301 is started to drive the driving gear 302 and the transmission chain 304 to rotate. The transmission chain 304 drives the telescopic arm 31 to extend through the connecting block 305, so that the locking protrusion 316 extends into the hole on the other side of the rolling plate. The second hydraulic column 24 stops contracting, and the drive motor 301 drives the transmission chain 304 to rotate in the opposite direction, so that the telescopic arm 31 contracts and drives the locking protrusion 316 to press against the inner wall of the rolling plate hole. The drive motor 301 stops rotating. The electromagnet 321 is energized and fixes the telescopic arm 31 with the cast iron block 315 by magnetic attraction, and the telescopic arm 31 is improved to lock the roll plate. Then the lifting frame is lifted to drive the sling to lift the roll plate. After moving to the stacking position, the reduction motor 416 is started to drive the driving gear 415 and the steering gear 414 to rotate. The steering gear 414 rotates to drive the rotating shaft 411 and the bearing plate 412 to rotate. The ball bearing 413 under the bearing plate 412 can reduce the friction when the bearing plate 412 rotates, and the hook The connecting seat 1, the C-type hook 2 and the locking arm 3 rotate along with the rotating shaft 411 to adjust the direction of the rolled plate, and then the lifting frame descends to place the rolled plate to the stacking position. The reduction motor 416 and the gear box 41 can make the hook connecting seat 1 and the C-type hook 2 rotate between 0 and 360 degrees. The unloading and stacking can be completed by lifting the rolled plate only once, which improves the work efficiency. The locking arm 3 and the telescopic arm 31 are used to limit and lock the holes on the other side of the rolled plate, thereby improving the safety of the rolling plate lifting operation.

[0057] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
