[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this invention, by setting up a starting limit motor, a limit guide post, a transmission sleeve, a main support rod, a reinforcing rib, a connecting guide rod, a limit clamping plate, and an auxiliary guide rod, the clamping device is first moved to a designated position by starting the lifting mechanism. Then, the limit motor is started, causing it to drive the adjusting screw to rotate. The rotation of the adjusting screw causes the transmission horizontal plate to drive the transmission sleeve to rise. Through the cooperation of the limit slide groove, the transmission sleeve drives the connecting protrusion to move.

The movement of the transmission chain is assisted by the reciprocating adjusting block, which in turn drives the transmission plate to move. The two ends of the lifting mechanism are fixedly connected to the transmission plate and the connecting top plate, respectively, thus realizing the workpiece handling. Furthermore, by the reciprocating adjusting block sliding in the reciprocating adjusting groove, the adjusting transmission block reciprocates in the adjusting slide groove, thus facilitating subsequent workpiece handling and greatly improving the practicality of the automatic loading and unloading device.

[0024] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0025] like Figure 1-6 As shown, the present invention provides a technical solution: an automatic loading and unloading device for industrial steel storage, comprising a support column 1, the top of which is fixedly connected to a limiting top frame 4, a support block 2 fixedly connected to the bottom of the support column 1, and a self-locking caster wheel 3 fixedly connected to the bottom of the support block 2. The limiting top frame 4 is provided on the top of the support column 1, a connecting beam 5 is provided on the limiting top frame 4, and a reciprocating device 6 and a clamping device 7 are provided on the connecting beam 5.

[0026] The reciprocating device 6 includes a protective chain box 603, which is fixedly connected to a limiting top frame 4. The limiting top frame 4 is U-shaped, and the two ends of the connecting beam 5 are fixedly connected to the protective chain box 603 and the limiting top frame 4. A support frame 602 is fixedly connected to the top of the protective chain box 603, and a power motor 601 is fixedly connected to the support frame 602. A transmission chain 606 and a transmission sprocket 605 are provided in the protective chain box 603, and both ends of the transmission chain 606 are mounted on the transmission sprocket 605. The protective chain box 603 effectively prevents external debris from affecting the normal operation of the transmission chain 606, greatly improving the safety of the transmission chain 606. The power motor 601 is used to drive one of the transmission sprockets 605 to rotate, and through the cooperation of the other transmission sprocket 605, the transmission chain 606 moves in the protective chain box 603.

[0027] The output end of the power motor 601 passes through the protective chain box 603 and is fixedly connected to one of the transmission sprockets 605. An adjusting transmission block 607 is provided at the bottom of the transmission chain 606, and a reciprocating adjusting groove 609 is provided on the adjusting transmission block 607. A reciprocating adjusting block 608 is fixedly connected to the bottom of the transmission chain 606, and the reciprocating adjusting block 608 is slidably connected to the reciprocating adjusting groove 609. An adjusting slide groove 604 is provided on the protective chain box 603, and the adjusting transmission block 607 is slidably connected in the adjusting slide groove 604. The adjusting transmission block 607 drives the auxiliary transmission block 10 to move horizontally, thus realizing the workpiece handling. Furthermore, by the reciprocating adjusting block 608 sliding in the reciprocating adjusting groove 609, the adjusting transmission block 607 drives the auxiliary transmission block 10 to move reciprocally, facilitating subsequent workpiece loading and unloading.

[0028] The clamping device 7 includes a limit motor 701, which is fixedly connected to the top of the connecting top plate 702. An adjusting screw 712 is inserted into the connecting top plate 702, and the output end of the limit motor 701 passes through the connecting top plate 702 and is fixedly connected to one end of the adjusting screw 712. Limit guide posts 703 and auxiliary limit rods 704 are provided at both ends of the connecting top plate 702. A transmission sleeve 705 is sleeved at the bottom of the limit guide posts 703 and the auxiliary limit rods 704. A limit groove 715 is provided on the transmission sleeve 705. A transmission cross plate 714 is provided at the top of the transmission sleeve 705, and the transmission cross plate 714 is threadedly connected to the adjusting screw 712. The main support rod 707 is fixedly connected to the bottom of the limiting guide post 703, and the main support rod 707 is slidably connected to the limiting slide groove 715. The main support rod 707 is L-shaped, and both ends of the transmission cross plate 714 are fixedly connected to the top of the transmission sleeve 705.

[0029] The bottom of the transmission sleeve 705 is provided with a connecting protrusion 706, and the main support rod 707 is provided with a reinforcing rib 708. Both ends of the reinforcing rib 708 are fixedly connected to the main support rod 707. The connecting protrusion 706 is fixedly connected to both sides of the transmission sleeve 705. The transmission sleeve 705 is square in shape. One end of the linkage guide rod 709 is rotatably connected to the main support rod 707. One end of the main support rod 707 is provided with a linkage guide rod 709, and the other end of the linkage guide rod 709 is fixedly connected to the limiting clamp 710. The wear-resistant layer 711 is fixedly connected to the limiting clamp 710. Both the linkage guide rod 709 and the connecting protrusion 706 are equipped with an auxiliary spring 716 and an auxiliary guide rod 713. The two ends of the auxiliary spring 716 are fixedly connected to the connecting protrusion 706 and the linkage guide rod 709, respectively. The two ends of the auxiliary guide rod 713 are rotatably connected to the connecting protrusion 706 and the linkage guide rod 709, respectively. The auxiliary guide rod 713 is located on both sides of the auxiliary spring 716.

[0030] The limit motor 701 drives the adjusting screw 712 to rotate, causing the transmission horizontal plate 714 to move the transmission sleeve 705 up and down. During the lifting and lowering process, the transmission sleeve 705 slides on the limit groove 715 through the main support rod 707, thereby limiting the lifting distance of the transmission sleeve 705. The cooperation of the auxiliary limit rod 704 and the limit guide post 703 also serves to limit the transmission horizontal plate 714, so that the transmission horizontal plate 714 can move the transmission sleeve 705 up and down. The movement of the transmission sleeve 705 drives the connecting protrusion 706 to move up and down. With the assistance of the auxiliary guide rod 713, one end of the connecting guide rod 709 drives the limit clamping plate 710 and the wear-resistant layer 711 to clamp and fix the workpiece. The cooperation of the two sets of wear-resistant layers 711 greatly improves the stability of the workpiece during movement and effectively prevents the workpiece from falling. The cooperation of the reinforcing rib 708 greatly improves the stability of the main support rod 707. The elastic force of the auxiliary spring 716 is used to assist in the reset of the limiting clamp 710, so as to facilitate the transport of the limiting clamp 710 and the wear-resistant layer 711 to the subsequent workpiece. When the connecting protrusion 706 moves up and down, the auxiliary guide rod 713 is used to pull one end of the connecting guide rod 709 to move, so as to fix the workpiece by the subsequent limiting clamp 710.

[0031] A lifting mechanism 9 is provided on the top of the connecting top plate 702. A transmission plate 8 is provided at one end of the lifting mechanism 9. A protective box 11 and an auxiliary transmission block 10 are provided on the top of the transmission plate 8. The two ends of the auxiliary transmission block 10 are fixedly connected to the adjusting transmission block 607 and the protective box 11, respectively. The steering motor 12 is fixedly connected to one side of the protective box 11. The second transmission bevel gear 14 and the first transmission bevel gear 13 are both installed in the protective box 11. The output end of the steering motor 12 passes through the protective box 11 and is fixedly connected to the first transmission bevel gear 13. The bottom of the second transmission bevel gear 14 passes through the protective box 11 and is fixedly connected to the top of the transmission plate 8.

[0032] The lifting mechanism 9 is fixedly connected to the transmission plate 8 and the connecting top plate 702 at both ends, respectively. The auxiliary limit rod 704 and the limit guide post 703 are fixedly connected to both ends of the connecting top plate 702. The protective box 11 is equipped with a steering motor 12, and the output end of the steering motor 12 is equipped with a transmission bevel gear 13. The bottom of the transmission bevel gear 13 is equipped with a transmission bevel gear 14 that meshes with it. The adjusting transmission block 607 drives the workpiece to move through the cooperation of the auxiliary transmission block 10. By starting the steering motor 12, the transmission bevel gear 13 is driven to rotate. Through the cooperation of the transmission bevel gear 14, the limit clamp 710 drives the workpiece to rotate. The lifting mechanism 9 is used to drive the workpiece to move in height, so as to facilitate the subsequent stacking of workpieces.

[0033] The working principle of this invention is as follows: First, the support column 1 is pushed to move the automatic loading and unloading device to a suitable position through the cooperation of the support block 2 and the self-locking universal wheel 3. Then, the lifting mechanism 9 is activated to adjust the height of the clamping device 7. Subsequently, the limit motor 701 is activated, which drives the adjusting screw 712 to rotate. The rotation of the adjusting screw 712 causes the transmission cross plate 714 to drive the transmission sleeve 705 to rise. With the assistance of the limit slide groove 715, the connecting protrusion 706 rises. The rise of the connecting protrusion 706, through the cooperation of the auxiliary guide rod 713 and the main support rod 707, pulls one end of the connecting guide rod 709 to move. Therefore, the limit clamping plate 710 on one end of the connecting guide rod 709 drives the wear-resistant layer 711 to clamp and fix the workpiece.

[0034] Then, the power motor 601 is started, and through the cooperation of the transmission sprocket 605, the transmission chain 606 moves in the protective chain box 603. The movement of the transmission chain 606 causes the reciprocating adjusting block 608 to drive the adjusting transmission block 607 to move horizontally. The adjusting transmission block 607, through the cooperation of the auxiliary transmission block 10, drives the transmission plate 8 to move. The two ends of the lifting mechanism 9 are fixedly connected to the transmission plate 8 and the connecting top plate 702, respectively. Thus, the workpiece on the limiting clamping plate 710 is transported. And through the sliding of the reciprocating adjusting block 608 in the reciprocating adjusting groove 609, the adjusting transmission block 607 reciprocates in the adjusting slide groove 604, so as to facilitate the loading and unloading of subsequent workpieces by the wear-resistant layer 711.
