[0016] The present invention provides a lifting device for an automobile automated production line, which has the following beneficial effects:

[0017] 1. The present invention can drive the first bidirectional screw to rotate by the operation of the second motor. During the rotation of the first bidirectional screw, the two groups of first sliding seats connected at the outer ends thereof can be driven to slide and adjust their positions. The two groups of first sliding seats are respectively connected to the displacement frames. Through the adjustment of the first sliding seats, the spacing between the two groups of displacement frames can be adjusted. In addition, the second motor can drive the second bidirectional screw to rotate. During the rotation of the second bidirectional screw, the two groups of sliding blocks connected at the outer ends thereof can be driven to displace, which makes it possible to adjust the spacing between the hoisting hoists. Since the hoisting hoist is connected to the hoisting swivel head through the hoisting steel cable, the above operations can make the four groups of hoisting platforms adjust their horizontal and vertical positions, thereby being able to The lifting platform is moved to the specified lifting point of the automobile component, thereby facilitating the subsequent lifting operation of the automobile component. The adjustment design of the displacement frame and the sliding block can enable the equipment to flexibly adapt to the lifting points of automobile components of various specifications. In addition, the use of the lifting steel cable can adjust the lifting position of the lifting platform within a small range. The lifting hoist adjusts the length of the wound lifting steel cable to adjust the specific height of the lifting platform, and the lifting turntable can adjust the placement direction of the lifting platform. Through this design, the equipment can adjust the position of the lifting platform again according to the specific lifting point of the automobile component, which further improves the adjustment flexibility of the equipment and also enables the equipment to use various irregular-shaped automobile components.

[0018] 2. The staff of the present invention can choose to lift or clamp according to the positioning point of the automobile part. If the positioning point of the automobile part is clamped, the staff will move the clamping part of the automobile part into the interior of the lifting platform. At this time, the hydraulic cylinder will work to drive the clamping plate A to move down, so that the clamping part of the automobile part can be fixed between the clamping plate A and the lifting platform. If the automobile part is lifted, the staff will pass the hook through the lifting part of the automobile part to realize the lifting of the automobile part by the lifting platform. Through this design, the equipment can adjust the docking plan according to the fixing method of the automobile part without replacing parts, which can greatly improve the flexibility of the equipment.

[0019] When the lifting platform of the present invention clamps and fixes the automobile component, the clamping plate A can drive the first rotating frame to rotate during the downward movement. During the rotation and adjustment of the first rotating frame, the hook can be driven to rotate through the rotating head. During the rotation of the hook, the lifting pile can be driven to move down from the bottom end of the lifting platform through the rotation of the second rotating frame. During the downward movement of the lifting pile, the tensioning cable can be rotated out from the inside of the torsion spring tooth seat and drive the torsion spring tooth seat to rotate. During the rotation of the torsion spring tooth seat, it can engage with the tooth groove at the rear end of the clamping plate B to push the clamping plate B to stretch the return spring and rise from the inside of the lifting platform. This enables the equipment to clamp and fix the automobile component, and the clamping plate B can provide an upward force to assist the clamping plate A in clamping. When the equipment is hoisting and fixing the automobile component, the staff uses the closed cable to connect the locking hook and the rope groove, so that the opening of the hook is closed, which can effectively prevent the automobile component from falling during subsequent movement. When the hook is unhooked, the hydraulic cylinder drives the clamping plate A to move downward, which enables the first rotating frame to drive the hook to rotate. Because the direction of the hook rotation driven by the first rotating frame is inward, the hook and the rotating head can be locked to prevent the automobile parts from shaking during the lifting process. During the rotation of the hook, the second rotating frame will drive the lifting pile to move upward and drive the clamping plate B to be ejected, which enables the two fixed ends of the closing cable to move relative to each other, thereby avoiding the closing cable from being pulled and damaged, thereby affecting the lifting stability of the hook. Through the above operations, when the equipment is lifting or clamping automobile parts, the lifting parts and the clamping parts can assist the currently used fixing parts for auxiliary fixation when they are not in use. This allows the equipment to have both lifting and clamping automobile parts fixing methods while maximizing the advantages of multiple parts for auxiliary positioning, which further improves the connection stability between the equipment and automobile parts.

The second rotating frame 1201 is fixedly connected to the hook 9, and the hook 9 rotates to cause the second rotating frame 1201 to drive the lifting pile 1202 to move inside the lifting platform 5. The displacement of the lifting pile 1202 drives the tension cable 1203 from the torsion spring tooth seat 1204. 204 is unscrewed, the tension cable 1203 is unscrewed from the torsion spring tooth seat 1204, driving the torsion spring tooth seat 1204 to rotate, the torsion spring tooth seat 1204 is engaged with the tooth groove 1206, and the rotation of the torsion spring tooth seat 1204 drives the clamping plate B 1205 to stretch the return spring 1208 and rise from the inside of the lifting platform 5. A closing cable 13 is provided between the locking hook 10 and the rope receiving groove 1207, and the closing cable 13 makes the inside of the hook 9 closed;

[0030] The specific operation is as follows: the first motor 202 is operated to drive the first bidirectional screw rod 203 to rotate. During the rotation of the first bidirectional screw rod 203, the two groups of first sliding seats 204 connected at the outer ends thereof can be driven to slide and adjust. The two groups of first sliding seats 204 are respectively connected to the displacement frame 205. Through the adjustment of the first sliding seat 204, the spacing between the two groups of displacement frames 205 can be adjusted. In addition, the second motor 206 is operated to drive the second bidirectional screw rod 207 to rotate. During the rotation of the second bidirectional screw rod 207, the two groups of sliding blocks 208 connected at the outer ends thereof can be driven to displace, which makes it possible to adjust the spacing between the hoisting hoists 209. Because the hoisting hoist 209 is connected to the hoisting turntable 4 through the hoisting cable 3, the above operation can make the four The lifting platform 5 is assembled to adjust its horizontal and vertical positions, so that the lifting platform 5 can be moved to the lifting point specified for the automobile component, thereby facilitating the subsequent automobile component lifting operation. The positioning design of the displacement frame 205 and the sliding block 208 can enable the equipment to flexibly adapt to the lifting points of automobile components of various specifications. In addition, the use of the lifting steel cable 3 can adjust the lifting position of the lifting platform 5 within a small range, and the lifting hoist 209 adjusts the length of the wound lifting steel cable 3 to adjust the specific height of the lifting platform 5, and the lifting turntable 4 can adjust the placement direction of the lifting platform 5. Through this design, the equipment can adjust the position of the lifting platform 5 again according to the specific lifting point of the automobile component, which further improves the adjustment flexibility of the equipment and also enables the equipment to be used in various For an irregular-shaped automobile part, after the position positioning of the lifting platform 5 is completed, the staff can choose to lift or clamp it according to the positioning point of the automobile part. If the positioning point of the automobile part is clamped, the staff moves the clamping part of the automobile part into the lifting platform 5. At this time, the hydraulic cylinder 6 works to drive the clamping A plate 7 to move down, so that the clamping part of the automobile part can be fixed between the clamping A plate 7 and the lifting platform 5. If the automobile part is lifted, the staff passes the hook 9 through the lifting part of the automobile part, and the lifting platform 5 can lift the automobile part. Through this design, the equipment can adjust the docking plan according to the fixing method of the automobile part without replacing parts, which can greatly improve the flexibility of the equipment. When the lifting platform 5 clamps and fixes the automobile part, When the clamping A plate 7 moves downward, it can drive the first rotating frame 11 to rotate. When the first rotating frame 11 rotates and adjusts its position, it can drive the hook 9 to rotate through the rotating head 8. When the hook 9 rotates, it can drive the lifting pile 1202 to move downward from the bottom end of the lifting platform 5 through the rotation of the second rotating frame 1201. When the lifting pile 1202 moves downward, it can drive the tension cable 1203 to rotate out from the inside of the torsion spring tooth seat 1204 and drive the torsion spring tooth seat 1204 to rotate. When the torsion spring tooth seat 1204 rotates, it can engage with the rear end tooth groove 1206 of the clamping B plate 1205 to push the clamping B plate 1205 to stretch the reset spring 1208 and rise from the inside of the lifting platform 5. This allows the equipment to clamp and fix automobile parts.The clamping plate B 1205 can provide an upward force to assist the clamping plate A 7 in clamping. When the equipment is hoisting and fixing the automobile parts, the staff uses the closing cable 13 to connect the locking hook 10 and the rope groove 1207, which can make the opening of the hook 9 appear closed, which can effectively prevent the automobile parts from being unhooked during the subsequent movement. In addition, the hydraulic cylinder 6 drives the clamping plate A 7 to move downward, which can make the first rotating frame 11 drive the hook 9 to rotate. Because the direction of rotation of the hook 9 driven by the first rotating frame 11 is inward, this makes it possible to lock the hook 9 and the rotating head 8 to prevent the automobile parts from shaking during the lifting process. During the rotation of the hook 9, the second rotating frame 1201 will drive the lifting pile 1202 to move upward, and drive the clamping plate B 1205 to the top This allows the two fixed ends of the closing cable 13 to move relative to each other, thereby preventing the closing cable 13 from being pulled and damaged, which would affect the lifting stability of the hook 9. Through the above operations, when the equipment is lifting or clamping the automobile parts, the lifting parts and the clamping parts can assist the currently used fixing parts to perform auxiliary fixation when they are not in use. This allows the equipment to have both lifting and clamping two automobile parts fixing methods while also maximizing the advantages of multiple parts for auxiliary positioning, which further improves the connection stability between the equipment and the automobile parts. The docking frame 1 can be connected to the elevator outside the equipment. When the equipment completes the lifting of the automobile parts, the elevator can drive the displacement of the automobile parts for automated processing.

[0031] In summary, when the automobile automated production line lift hoist is used, the first motor 202 is first operated to drive the first bidirectional screw rod 203 to rotate. During the rotation of the first bidirectional screw rod 203, the two sets of first sliding seats 204 connected to the outer ends thereof can be driven to slide and adjust their positions. The two sets of first sliding seats 204 are respectively connected to the displacement frames 205. By adjusting the position of the first sliding seats 204, the distance between the two sets of displacement frames 205 can be adjusted.

[0032] Then, the second motor 206 is operated to drive the second bidirectional screw rod 207 to rotate. During the rotation of the second bidirectional screw rod 207, the two sets of sliding blocks 208 connected to the outer ends thereof are driven to move, so that the spacing between the hoisting hoists 209 can be adjusted. Since the hoisting hoists 209 are connected to the hoisting turntable 4 through the hoisting steel cables 3, the above operations can adjust the horizontal and vertical positions of the four sets of hoisting platforms 5, so that the hoisting platforms 5 can be moved to the specified hoisting points of the automobile parts, thereby facilitating the subsequent hoisting operations of the automobile parts.

[0033] Then, after the position positioning of the lifting platform 5 is completed, the staff can choose to lift or clamp the automobile component according to the positioning point of the automobile component. If the positioning point of the automobile component is clamped, the staff moves the clamping part of the automobile component into the lifting platform 5. At this time, the hydraulic cylinder 6 works to drive the clamping plate A 7 to move down, so that the clamping part of the automobile component can be fixed between the clamping plate A 7 and the lifting platform 5. If the automobile component is lifted, the staff passes the hook 9 through the lifting part of the automobile component, and the lifting platform 5 can be used to lift the automobile component. Through this design, the equipment can adjust the docking plan according to the fixing method of the automobile component without replacing parts, which can greatly improve the flexibility of the equipment.

[0034] Then, when the hoisting platform 5 clamps and fixes the automobile component, the clamping A plate 7 can drive the first rotating frame 11 to rotate during the downward movement. During the rotation and adjustment of the first rotating frame 11, the hook 9 can be driven to rotate through the rotating head 8. During the rotation of the hook 9, the second rotating frame 1201 can be used to drive the lifting pile 1202 to move downward from the bottom end of the hoisting platform 5. During the downward movement of the lifting pile 1202, the tension cable 1203 can be rotated out from the torsion spring tooth seat 1204 and drive the torsion spring tooth seat 1204 to rotate. During the rotation of the torsion spring tooth seat 1204, the engagement with the rear end tooth groove 1206 of the clamping B plate 1205 can be achieved, pushing the clamping B plate 1205 to stretch the return spring 1208 and lift it out of the hoisting platform 5. This allows the clamping B plate 1205 to provide an upward force to assist the clamping of the clamping A plate 7 when the equipment clamps and fixes the automobile component.

[0035] Then, when the equipment is lifting and fixing the automobile parts, the staff uses the closing cable 13 to connect the locking hook 10 and the rope receiving groove 1207, so that the opening of the hook 9 is closed, which can effectively prevent the automobile parts from being unhooked during the subsequent movement. In addition, the hydraulic cylinder 6 drives the clamping plate A 7 to move downward, which can make the first rotating frame 11 drive the hook 9 to rotate. Because the direction of the first rotating frame 11 driving the hook 9 to rotate is inward, the hook 9 and the rotating head 8 can be locked to prevent the automobile parts from shaking during the lifting process. During the rotation of the hook 9, the second rotating frame 1201 will drive the lifting pile 12 02 moves upward and drives the clamping plate B 1205 to be ejected, which allows the two fixed ends of the closing cable 13 to move relative to each other, thereby preventing the closing cable 13 from being pulled and damaged, thereby affecting the lifting stability of the hook 9. Through the above operations, when the equipment is lifting or clamping the automobile parts, the lifting parts and the clamping parts can assist the currently used fixing parts to perform auxiliary fixation when they are not in use. This allows the equipment to have both lifting and clamping two automobile parts fixing methods while maximizing the advantage of multiple parts for auxiliary positioning, which further improves the connection stability between the equipment and the automobile parts.

[0036] Finally, because the docking frame 1 can be connected with the elevator outside the equipment, when the equipment completes the lifting of the automobile parts, the automobile parts can be driven to move and be automatically processed through the operation of the elevator.
