This structural design is ingenious.

DETAILED DESCRIPTION
[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0029] Embodiment 1, as Figure 1 , Figure 3 , Figure 5 As shown, a dock lifting equipment with high stability is provided, wherein the first connecting plate 4 is welded between the first reinforcing rib 3 and the column 2, the first servo motor 5 is detachably connected to the upper end of a first connecting plate 4, the output end of the first servo motor 5 is provided with a coupling, the output end of the first servo motor 5 passes through the first connecting plate 4 and is detachably connected to the screw rod 6 through the provided coupling, the guide rod 7 is welded between another first connecting plate 4 and the base plate 1, a U-shaped moving frame 8 is threadedly connected to the outer surface of the screw rod 6, the other U-shaped moving frame 8 is slidably connected to the outer surface of the guide rod 7, the support plate 9 is welded to the lower ends of the two U-shaped moving frames 8, the second reinforcing rib 10 is welded to one side of the U-shaped moving frame 8, the bottom of the second reinforcing rib 10 is welded to the support plate 9, and the lower end of the base plate 1 is provided with a driving wheel 11 and two auxiliary wheels 12.
[0030] Through the cooperation of the driving wheel 11 and the auxiliary wheel 12, the two bottom plates 1 can be driven to move stably very smoothly. After moving into place, it is only necessary to start the two first servo motors 5 at the same time, and the screw rod 6 will rotate immediately to drive the U-shaped moving frame 8 and the support plate 9 to move downward. When the support plate 9 contacts the ground and continues to move downward, it will cleverly push the entire device up, so that the driving wheel 11 and the auxiliary wheel 12 are away from the ground. At this time, the entire device is stably supported by the two support plates 9, which effectively avoids the safety hazards caused by unstable wheel support and ensures the safety and reliability of the operation process.
[0031] Embodiment 2, as Figure 1-Figure 4 As shown, a dock lifting equipment with high stability is shown, in which a movable column 13 is movably connected with the column 2, two racks 14 are respectively welded on both sides of the movable column 13, a second connecting plate 15 is welded with the front end of the column 2, and a third connecting plate 16 is welded with the rear end of the column 2. A second servo motor 17 is detachably connected with the front end of the second connecting plate 15, and a coupling is provided at the output end of the second servo motor 17. The output end of the second servo motor 17 passes through the second connecting plate 15 and is detachably connected with the first rotating rod 18 through the provided coupling. A first gear 19 is welded with the outer surface of the first rotating rod 18, a second gear 20 is meshed with the first gear 19, and the second gear 20 is welded to the outer surface of the second rotating rod 21, two third gears 22 are respectively welded to the outer surfaces of the first rotating rod 18 and the second rotating rod 21, and the two third gears 22 are respectively meshed with the two racks 14.
[0032] When the two second servo motors 17 are started at the same time to drive the first rotating rod 18 to rotate, the first gear 19, the second gear 20 and the third gear 22 are respectively meshed with the rack 14 to achieve a smooth rise of the movable column 13 in the column 2. This structural design is ingenious. Only two motors 17 need to be started to drive multiple components to work together and efficiently complete the height adjustment of the fourth connecting plate 23 and the guide rail 24.
[0033] Embodiment three, as Figure 1 , Figure 6 As shown, a dock lifting equipment with high stability is shown, the fourth connecting plate 23 is welded to the top of the movable column 13, the guide slide rail 24 is detachably connected to the upper ends of the two fourth connecting plates 23, the electric hoist 25 is slidably installed on the guide slide rail 24, the two connecting vertical plates 26 are symmetrically welded to the lower end of the electric hoist 25, one end of the two movable rods 27 are welded with a limiting plate 28, the other end of the two movable rods 27 are welded with a limiting block 29, and the surface of the movable rod 27 is located between the inner side of the connecting vertical plate 26 and the limiting block 29 and is provided with a spring 30.
[0034] With the help of the coordinated cooperation of the electric hoist 25 and the guide rail 24, efficient horizontal movement of the goods can be achieved. When the suspended goods shake during movement, the shaking of the cable will drive the limit block 29 to move and squeeze the spring 30. At this time, the elastic force generated by the spring 30 will push the cable in the opposite direction to buffer the force generated by the shaking, thereby preventing the goods from falling off due to excessive shaking.
[0035] It should be noted that the present invention is a dock lifting equipment with high stability. When in use, the driving wheel 11 and the auxiliary wheel 12 can drive the two bottom plates 1 to move stably, and then the entire device can be moved to the desired position. After the movement is completed, the two first servo motors 5 are started at the same time to drive the screw rod 6 to rotate. At this time, the U-shaped moving frame 8 will drive the support plate 9 to move downward with the rotation of the screw rod 6. After the support plate 9 contacts the ground, the support plate 9 continues to move downward, which will push the entire device up, and then the driving wheel 11 and the auxiliary wheel 12 will be away from the ground. At this time, the entire device will be stably supported by the two support plates 9, and the lifting and hoisting operation can be carried out at this time.
[0036] When the height of the device needs to be adjusted, the two second servo motors 17 are started at the same time to drive the first rotating rod 18 to rotate. At this time, the first rotating rod 18 will drive the first gear 19 to rotate. Since the first gear 19 is meshed with the second gear 20, the second gear 20 will also rotate synchronously. When the second gear 20 rotates, it will drive the second rotating rod 21 to rotate synchronously. When the first rotating rod 18 and the second rotating rod 21 rotate synchronously, the two third gears 22 will be driven to rotate. Since the two third gears 22 are respectively meshed with the two racks 14, when the third gear 22 rotates, it will drive the two movable columns 13 to move upward in the column 2, and then drive the fourth connecting plate 23 and the guide slide rail 24 on the top of the movable column 13 to adjust the height. After adjusting to the appropriate height, the lifting and hoisting operation can be carried out.
[0037] When lifting and hanging goods, the goods can be lifted by the electric hoist 25 in cooperation with the hook at its lower end. Since the electric hoist 25 is slidably installed on the guide rail 24, the lifted goods can be driven to move horizontally. When driving the goods to move horizontally, the cable connected to the hook will shake, and the shaking will drive the two limit blocks 29 to move horizontally. The limit blocks 29 will compress the spring 30 when moving. At this time, the cable will be pushed back under the action of the elastic force of the spring 30, thereby buffering the force generated by the shaking of the cable and preventing the goods from falling off due to a large shaking amplitude.
[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
