[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] Example 1: Please refer to Figures 1 to 10 :

[0040] This utility model proposes a port lifting device, including: a support frame 1;

[0041] The support frame 1 has two sets, and a landing gear 2 slides between the two sets of support frames 1. Two sets of sliding seats 22 slide on the landing gear 2. A base plate 23 is fixed to the lower end of the two sets of sliding seats 22. A partition 24 is installed at the lower end of the base plate 23. Four sets of connecting columns 241 are fixed between the partition 24 and the base plate 23. A motor mount 242 is bolted to the partition 24. A first motor 243 is bolted to the motor mount 242. A gear is fixed to the output shaft of the first motor 243. A rotatable rotating disk 25 is installed at the lower end of the partition 24. A ring array is mounted on the rotating disk 25. The rotating disk 25 has six sets of positioning holes 251. A rectangular plate 26 is fixed to the lower end of the rotating disk 25. The lower end of the rectangular plate 26 is bolted to a first support 261 and a second support 262. A flip plate 263 is installed between the first support 261 and the second support 262 through a bearing. A fixing post 27 is fixed to the lower end of the flip plate 263. An mounting plate 272 is installed on the fixing post 27. Two sets of clamping arms 273 are hinged on the mounting plate 272. A hinge seat 271 is fixed to the lower end of the fixing post 27. A connecting plate 274 is connected between the two sets of clamping arms 273 and the hinge seat 271.

[0042] In this embodiment of the disclosure,

[0043] Both sets of support frames 1 are bolted to the upper ends of gearboxes 11, and a second motor 111 is bolted to each gearbox 11. Sprockets are fixed to the output shafts of both gearboxes 11. A rotating rod 12 is mounted to the upper end of each support frame 1 via bearings. A sprocket is fixed to the rotating rod 12. The rotating rod 12 and gearboxes 11 are connected by a chain drive. Two sets of winding drums 121 are fixed to the rotating rod 12. Connecting frames 21 are fixed to both sides of the landing gear 2. Two sets of lifting lugs 211 are fixed to the connecting frames 21. 211 is used to connect the load-bearing rope. The upper end of the load-bearing rope is fixed on the winding drum 121. Its function is to use the No. 2 motor 111 as the power source, and after the gearbox 11 is changed, the power is efficiently transmitted to the rotating rod 12 by the transmission combination of the sprocket and the chain. The rotation of the rotating rod 12 drives the two sets of winding drums 121 fixed thereto to rotate synchronously. The winding drum 121 is connected to the lugs 211 on the connecting frame 21 on both sides of the landing gear 2 through the load-bearing rope. In this way, the landing gear 2 can be accurately controlled to rise and fall smoothly between the two sets of support frames 1.

[0044] In this embodiment of the disclosure,

[0045] Both ends of the landing gear 2 are bolted with mounting bases 221. A third motor 222 is bolted to the mounting base 221 near the left side of the landing gear 2, and a pulley is mounted on the mounting base 221 near the right side of the landing gear 2 via a bearing. A pulley is fixed to the output shaft of the third motor 222. A transmission belt 223 connects the two sets of pulleys and is fixedly connected to the sliding seat 22. Its function is as follows: the third motor 222 serves as the power output end. When it starts running, it drives the pulley on its output shaft to rotate. Since the two sets of pulleys are connected by the transmission belt 223, the power is transmitted to the pulley on the right mounting base 221, thereby driving the transmission belt 223 to run. The transmission belt 223 is fixedly connected to the sliding seat 22, which allows the sliding seat 22 to slide flexibly left and right on the landing gear 2.

[0046] Example 2, based on Example 1,

[0047] A gear is fixed on the shaft of the rotating disk 25. The gear on the shaft of the rotating disk 25 meshes with the gear on the output shaft of the first motor 243. A slide rail seat 244 is bolted to the lower end of the partition 24. A positioning rod 245 slides on the slide rail seat 244. A hydraulic rod 246 is installed on the partition 24. The piston rod of the hydraulic rod 246 is fixedly connected to the upper end of the positioning rod 245. Its function is to enable the first motor 243 to precisely drive the rotating disk 25 to rotate. When the rotating disk 25 rotates to the target angle, the hydraulic rod 246 is activated. Its piston rod pushes the positioning rod 245 down and inserts it into the positioning hole 251 on the rotating disk 25. This operation can effectively lock the position of the rotating disk 25 and prevent accidental rotation during the grabbing and handling of goods.

[0048] Example 3, based on Examples 1 and 2,

[0049] A slide plate 2621 is fixed on the second support 262. A toothed plate 2625 slides in the slide groove on the slide plate 2621. A gear is fixed on the rotating shaft of the tilting plate 263. The toothed plate 2625 meshes with the gear on the rotating shaft of the tilting plate 263. A cylinder seat 2622 is fixed on the slide plate 2621. A second hydraulic rod 2623 is installed on the cylinder seat 2622. A connecting plate 2624 is fixed on the piston rod of the second hydraulic rod 2623. The connecting plate 2624 is fixedly connected to the toothed plate 2625. Its function is to control the extension and retraction of the second hydraulic rod 2623, and to precisely adjust the tilting angle of the tilting plate 263, thereby flexibly changing the posture of the clamping arm 273. This allows the equipment to grasp goods more accurately and effectively avoid the problem of difficulty in grasping goods due to their special shape.

[0050] The working principle of this embodiment is as follows: The second motor 111 is started, and its power, after being changed by the gearbox 11, is transmitted to the rotating rod 12 via a sprocket and chain. The rotating rod 12 drives the winding drum 121 to rotate, releasing or retracting the load-bearing rope, thereby adjusting the height of the landing gear 2 between the two sets of support frames 1, so that the entire equipment reaches the height range of the cargo. Next, the third motor 222 is started, and its output shaft drives the pulley to rotate, causing the sliding seat 22 to slide on the landing gear 2 via the transmission belt 223, thereby adjusting the lateral position of the base plate 23 and the clamping device below, initially aligning with the cargo. At this time, the first motor 243 starts working, and the gear on its output shaft drives the gear on the rotating disk 25 shaft, causing the rotating disk 25 to rotate. This, combined with the positioning rod 245 controlled by the first hydraulic rod 246 at the lower end of the partition 24, is inserted into the positioning hole 251 of the rotating disk 25, precisely adjusting and locking the angle of the clamping device, completing the cargo positioning. When the equipment is accurately aligned with the cargo, the landing gear 2 begins to rise. During the rising process, the fixed... The fixed column 27, due to its relative position change, pulls the connecting plate 274, causing the two sets of clamping arms 273 to rotate around the hinge point on the mounting plate 272, gradually clamping the goods. Simultaneously, if the goods have a special shape, the second hydraulic rod 2623 can be activated. The piston rod of the second hydraulic rod 2623 pushes the connecting plate 2624, causing the toothed plate 2625 to slide within the sliding groove plate 2621. The toothed plate 2625 meshes with the gear on the rotating shaft of the tilting plate 263, causing the tilting plate 263 to rotate, flexibly adjusting the clamping arms 273. At an angle of 73°, the cargo is securely gripped. After the cargo is clamped, the winding drum 121 is continuously controlled to wind up the rope. The landing gear 2 lifts the cargo smoothly to the designated transport height. Then, by controlling the No. 3 motor 222 to change the position of the sliding seat 22 and adjusting the angle of the rotating disk 25, the cargo is transported to the target unloading location. After reaching the unloading location, the landing gear 2 descends. When the cargo touches the ground, the fixed column 27 moves upward relative to the ground, pushing the connecting plate 274, causing the clamping arm 273 to release the cargo.
