Two screw rods 203 are rotatably connected to the support seat 1, and the screw rods 203 are threadedly connected to the adjacent mobile frames 202. Two pulleys 205 are fixedly connected to the mobile frame 202, and a connecting rope 204 is wound around the pulley 205. One end of the connecting rope 204 is fixedly connected to the pull plate 206, and the other end of the connecting rope 204 is fixedly connected to the support frame 201. A supporting block 207 is rotatably connected to the pull plate 206, and one end of the supporting block 207 is engaged with the supporting plate 5. The bottom end of the screw rod 203 is fixedly connected to A first gear 208 is connected, a long shaft 210 is rotatably connected to the support seat 1, and two second gears 209 are fixedly connected to the long shaft 210, the first gear 208 is meshed with the adjacent second gear 209, the output shaft of the motor 3 is fixedly connected to one end of the long shaft 210, the overall cross-section of the support block 207 is an L-shaped structure, the overall cross-section of the pull plate 206 is an L-shaped structure, the cross-section of one end of the support block 207 is a trapezoidal structure, the loading structure 6 includes a connecting frame 601, the top of the support plate 5 is provided with a connecting frame 601, the bottom end of the connecting frame 601 is fixedly connected with four first brake universal wheels 604, the bottom end of the first brake universal wheel 604 conflicts with the support plate 5, the connecting frame There are two baffles 602 engaged on 601, and the baffles 602 are provided with through slots 603, that is, during use, the pallet 5 can be placed on the towing platform 10, and the two positioning posts 11 can pass through the pallet 5 when placing, so as to position the pallet 5. After the placement is completed, the connecting frame 601 can be placed on the pallet 5, and the placement of materials can be facilitated by removing the baffles 602 from the connecting frame 601. The through slots 603 can be used to facilitate the grabbing of the baffles 602. After the placement of materials is completed, the baffles 602 can be engaged with the connecting frame 601 again, and then the motor 3 is started, and the output shaft of the motor 3 rotates to drive the long shaft 210 to rotate, and the rotation of the long shaft 210 drives the two second gears 209 to rotate, and the first The second gear 209 rotates to drive the first gear 208 to rotate. The rotation of the first gear 208 will drive the screw rod 203 to rotate. The rotation of the screw rod 203 will threadably drive the mobile frame 202 to slide on the support frame 201. The movement of the mobile frame 202 will drive the two pulleys 205 to move. With the simultaneous movement of the four pulleys 205, the two pull plates 206 will move at the same time. The movement of the pull plates 206 will drive the support blocks 207 to move. The movement of the two support blocks 207 will drive the support plates 5 to move. The movement of the support plates 5 will drive the connecting frame 601 to move, thereby realizing the lifting of the materials. When the materials are lifted to the specified position, the output shaft of the motor 3 stops moving, and then the connecting frame 601 can be moved. By setting four first brake universal wheels 604, the movement of the connecting frame 601 can be facilitated.Continue to pull the connection frame 601 until it is completely removed from the support plate 5, and then the output shaft of the motor 3 can be rotated in the reverse direction to reset the support block 207. During use, when one connection frame 601 and the support plate 5 are lifted, the other support plate 5 and the connection frame 601 can be placed on the drag platform 10, and the material can be added to the inside of the connection frame 601. Therefore, the material can be taken and placed while the support plate 5 is moving, thereby shortening the time for lifting materials and improving the efficiency of lifting materials. In the process of resetting the support plate 5, it can be removed from the two support blocks 207, thereby avoiding the connection frame 601 from resisting it. Since the support block 207 and the pull plate 206 are rotationally connected, the support block 207 will rotate when it conflicts with the connection frame 601 and the support plate 5 during the resetting process. When it moves to the specified position, it will rotate in the reverse direction to a horizontal state under the action of gravity and conflict with the pull plate 206. Then, the next material lifting can be quickly performed, which is more convenient to use.

[0023] Specifically, Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the guide structure 4 includes a guide rail 401 and a slide 402, two guide rails 401 are fixedly connected to the movable frame 202, and the slide 402 is slidably connected to the guide rail 401, and the same pull plate 206 is fixedly connected to two adjacent slides 402, and the limiting structure 7 includes a guide column 701 and a connecting plate 702, two guide columns 701 are fixedly connected to the support plate 5, and the same connecting plate 702 is slidably connected to the two guide columns 701, and two clamping blocks 703 are fixedly connected to the top of the connecting plate 702, and the bottom end of the clamping block 703 is engaged with the connecting frame 601, and the outer sleeve of the guide column 701 is provided with a reset spring 704, one end of the reset spring 704 abuts against the support plate 5, and the other end of the reset spring 704 abuts against the connecting plate 702, the cross-section of the top of the clamping block 703 is a trapezoidal structure, and the cross-section of the top of the guide column 701 is a T-shaped structure, That is, during the movement of the pulling plate 206, the two sliding seats 402 can be driven to slide on the two guide rails 401 respectively, thereby preventing the pulling plate 206 from sliding during the movement, effectively improving the stability of use, and when the connecting frame 601 is placed on the supporting plate 5, the two clamping blocks 703 can be engaged with the bottom end of the connecting frame 601, thereby preventing the connecting frame 601 from falling from a high altitude during the movement, thereby effectively improving the safety of use, and when the connecting frame 601 needs to be removed from the supporting plate 5, the connecting plate 702 can be pressed to shrink the reset spring 704, and the two guide columns 701 can be provided to guide the connecting plate 702. The movement of the connecting plate 702 will drive the two clamping blocks 703 to move away from the connecting frame 601. When the two clamping blocks 703 are not engaged with the connecting frame 601, the connecting frame 601 can be moved, thereby facilitating the removal of the connecting frame 601 from the supporting plate 5.

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the driving structure 8 includes a connecting seat 801 and a short shaft 802, the supporting seat 1 is fixedly connected with the connecting seat 801, the connecting seat 801 is rotatably connected with the short shaft 802, the short shaft 802 is fixedly connected with a first synchronous wheel 803, the supporting seat 1 is fixedly connected with a connecting sleeve 807, the connecting sleeve 807 is rotatably connected with a rotating shaft 806, the rotating shaft 806 is fixedly connected with a second synchronous wheel 805, and a synchronous wheel 803 is wound around the second synchronous wheel 805.

The connecting block 904 is in the shape of a hexagonal prism, that is, when there is no power or a power outage during use, the screw rod 903 can be rotated by the knob 902, and the rotation of the screw rod 903 will drive the connecting block 904 to move toward the long axis 210. When the connecting block 904 is engaged with the long axis 210, the knob 902 can be stopped, and then the crank 808 can be held to rotate the short axis 802. The rotation of the short axis 802 will drive the first synchronous wheel 803 to rotate, and the rotation of the first synchronous wheel 803 will drive the first synchronous wheel 803 to rotate through the synchronous belt 804. The second synchronous wheel 805 is driven to rotate, and the rotation of the second synchronous wheel 805 will drive the rotating shaft 806 to rotate. Since the diameter of the first synchronous wheel 803 is smaller than the diameter of the second synchronous wheel 805, and the crank 808 is an L-shaped structure, it can save effort. The rotation of the rotating shaft 806 will drive the connecting block 904 to rotate, and the rotation of the connecting block 904 will drive the long shaft 210 to rotate. Therefore, when there is no electricity, or a power outage, or when the motor 3 fails, the material can still be lifted, thereby effectively improving the applicability of use.

[0025] When the present invention is in use, the pallet 5 can be placed on the towing platform 10 during use. When placing, the two positioning posts 11 can pass through the pallet 5, so that the pallet 5 can be positioned. After the placement is completed, the connecting frame 601 can be placed on the pallet 5. After the connecting frame 601 is placed on the pallet 5, the two clamping blocks 703 can be engaged with the bottom end of the connecting frame 601, so that the connecting frame 601 can be prevented from falling from a high altitude during the movement, thereby effectively improving the safety of use. By removing the baffle 602 from the connecting frame 601, the placement of materials can be facilitated. By providing the through slot 603, the baffle 602 can be easily grabbed. After the material is placed, the baffle 602 can be again placed between the connecting frame 601 The motor 3 is engaged, and then the output shaft of the motor 3 rotates to drive the long shaft 210 to rotate. The rotation of the long shaft 210 drives the two second gears 209 to rotate. The second gear 209 drives the first gear 208 to rotate. The rotation of the first gear 208 drives the screw rod 203 to rotate. The rotation of the screw rod 203 drives the movable frame 202 to slide on the support frame 201. The movement of the movable frame 202 drives the two pulleys 205 to move. With the simultaneous movement of the four pulleys 205, the two pull plates 206 move at the same time. During the movement of the pull plate 206, the two slide seats 402 can be driven to slide on the two guide rails 401 respectively, thereby preventing the pull plate 206 from sliding during the movement, effectively improving the stability of use, and the pull plate 20 6 movement will drive the support block 207 to move, the movement of the two support blocks 207 will drive the support plate 5 to move, the movement of the support plate 5 will drive the connection frame 601 to move, so as to realize the lifting of the material. When the material is lifted to the specified position, the output shaft of the motor 3 stops moving, and then by pressing the connection plate 702, the reset spring 704 contracts. By setting two guide columns 701, the connection plate 702 can be guided for movement. The movement of the connection plate 702 will drive the two clamping blocks 703 to move away from the connection frame 601. When the two clamping blocks 703 are not engaged with the connection frame 601, the connection frame 601 can be moved. By setting four first brake universal wheels 604, the movement of the connection frame 601 can be facilitated, and the connection frame 601 is continuously pulled until it is completely removed from the support plate 5. The bracket 207 is then removed from the upper and lower parts and the output shaft of the motor 3 is then rotated in the opposite direction to reset the bracket 207. During use, after one connecting frame 601 and the support plate 5 are lifted, the other support plate 5 and the connecting frame 601 can be placed on the towing platform 10 and materials can be added to the interior of the connecting frame 601. Therefore, materials can be taken and placed while the support plate 5 is moving, thereby shortening the time for lifting materials and improving the efficiency of lifting materials. During the resetting process of the bracket 5, it can be removed from the two brackets 207 to avoid being blocked by the connecting frame 601. Since the bracket 207 and the pulling plate 206 are rotationally connected, the bracket 207 will rotate when it conflicts with the connecting frame 601 and the bracket 5 during the resetting process.After moving to the designated position, it will rotate in the opposite direction to a horizontal state under the action of gravity and contact with the pull plate 206, and then the next material lifting can be carried out quickly, so that it is more convenient to use; When there is no power or a power outage during use, the screw rod 903 can be rotated by the knob 902. The rotation of the screw rod 903 will drive the connecting block 904 to move toward the long shaft 210. When the connecting block 904 is engaged with the long shaft 210, the knob 902 can be stopped, and then the crank 808 can be held to rotate the short shaft 802. The rotation of the short shaft 802 will drive the first synchronous wheel 803 to rotate. The rotation of the first synchronous wheel 803 will drive the second synchronous wheel 805 to rotate through the synchronous belt 804. The rotation of the second synchronous wheel 805 will drive the rotating shaft 806 to rotate. Since the diameter of the first synchronous wheel 803 is smaller than the diameter of the second synchronous wheel 805, and the crank 808 is an L-shaped structure, it can save effort. The rotation of the rotating shaft 806 will drive the connecting block 904 to rotate. The rotation of the connecting block 904 will drive the long shaft 210 to rotate. Therefore, when there is no electricity, or a power outage, or when the motor 3 fails, the material can still be lifted, thereby effectively improving the applicability of use.
