Technical Field

[0001] The present invention relates to the technical field of port cargo handling, and particularly relates to a hoisting type loading and unloading device for e-commerce goods. Background Art

[0002] In port logistics operations, the rapid loading and unloading of e-commerce goods is crucial for improving logistics efficiency and reducing costs. With the booming development of the e-commerce industry, the volume of e-commerce goods handled by ports is increasing day by day, and many problems have gradually emerged in the traditional port container crane loading and unloading method.

[0003] Currently, the remotely controlled container crane system widely used in ports has many limitations when facing e-commerce goods. When dealing with pallets loaded with e-commerce goods, the existing system is difficult to ensure the stability of the goods during hoisting. Due to the diverse types and inconsistent packaging specifications of e-commerce goods, the center of gravity distribution of the goods on the pallet is complex. The traditional remote control system lacks precise center of gravity adjustment ability, resulting in the goods being prone to shaking, tilting, and even falling during lifting and transportation. This not only causes damage to the goods but may also trigger safety accidents and affect the normal operation of port operations. In view of this, this paper proposes a hoisting type loading and unloading device for e-commerce goods. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Improve the safety of cargo loading and unloading

[0020] 1-1. Four anti-tilt multifunctional plates tightly surround the cargo, and the lock tongue buckles the pallet fork entrance, effectively preventing the cargo from scattering and the pallet from detaching; the first elastic airbag tightly wraps the cargo after expansion, further enhancing the fixing effect, and the opening between adjacent anti-tilt multifunctional plates is smaller than the size of the cargo packaging carton, ensuring the stability of the cargo during lifting and greatly reducing the risk of cargo damage or falling.

[0021] 1-2. The tension sensor monitors the squeezing force between the first elastic airbag and the cargo in real time. When the preset value is reached, the programmable logic controller controls the multi-stage hydraulic cylinder to stop working, ensuring moderate clamping force, preventing the cargo from being damaged or slipping due to improper clamping, and significantly improving the safety of the loading and unloading process.

[0022] 1-3. The cross center of gravity balance mechanism cooperates with the dual-axis inclination sensor to monitor the tilt state of the square frame in real time; once the tilt is detected, the programmable logic controller quickly controls the cross module to adjust in the X-axis and Y-axis directions to ensure the stability of the center of gravity of the pallet and cargo, reduce the risk of shaking and falling caused by the center of gravity shift, and provide more reliable safety protection for port loading and unloading operations.

[0023] 2. Improve loading and unloading efficiency

[0024] 2-1. The inclined surface design and automatic reset function of the lock tongue work together with the drive source to make the connection between the anti-tilt multifunctional plate and the pallet quick and convenient; the inclined surface on the lower surface of the lock tongue guides the lock tongue to quickly enter the fork opening, and the tension spring cooperates with the drive source to automatically control the extension and retraction of the lock tongue, simplifying the operating process, improving the speed of loading and unloading operations, and meeting the needs of rapid loading and unloading at the port.

[0025] 2-2. The programmable logic controller precisely controls the clamping force, and the cross gravity balance mechanism automatically adjusts the gravity center, reducing the adjustment time when lifting the tray and goods; without frequent manual intervention, the overall loading and unloading efficiency is greatly improved, which helps the port to handle more e-commerce goods per unit time.

[0026] 3. Enhance the accuracy of remote control

[0027] 3-1. This invention is combined with the remote control system of the port container crane. The operator can obtain the data of the tension sensor and the biaxial inclination sensor in real time through the system interface in the remote control room, and intuitively understand the clamping state and the gravity center situation of the goods; this enables the operator to control the actions of the crane more precisely, realizes the precise control of the goods loading and unloading process, reduces operation errors, and improves the quality of the loading and unloading operation.

[0028] 3-2. The coordinated work of the anti-tipping multifunctional plate and the cross gravity balance mechanism provides a more stable state for lifting goods during remote control; even in a complex port operation environment, the operator can accurately lift the goods to the designated position through the remote control system, improving the reliability and stability of the remote control.

[0029] 4. Reduce the operation difficulty

[0030] 4-1. The tension sensor and the biaxial inclination sensor feedback data in real time, and the programmable logic controller automatically controls the clamping force and adjusts the gravity center. The operator only needs to input simple operation instructions on the remote control system, without having to master complex mechanical principles and delicate operation skills, reducing the skill requirements for the operator, reducing the difficulty and uncertainty of manual operation, and facilitating new operators to get started quickly.

[0039] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] Embodiment 1:

[0041] As Figures 1 - 5 shown, a hoisting type loading and unloading device for e-commerce goods, which relates to goods stacked on a pallet and the pallet. The cross-section of the pallet is square, and the preferred cross-sectional size is 1100mm×1100mm. It includes a hook, which is a hook for hoisting goods in hoisting and lifting equipment such as bridge cranes, tower cranes, tractor-mounted cranes, and European single-arm cranes in the prior art. A square frame plate 4 is suspended and installed below the hook. Four anti-tilting multi-functional plates 3 are fixedly installed in a square shape below the four side edges of the square frame plate 4. The distance between the inner end faces of two opposite anti-tilting multi-functional plates 3 is 1160mm, which is greater than the width of the pallet, facilitating the four anti-tilting multi-functional plates 3 to be sleeved around the goods stacked on the pallet and the periphery of the pallet. The length that the following lock tongues 311 and the first elastic airbag 304 can extend out of the inner end face of the anti-tilting multi-functional plate 3 is 50mm. A number of expanded and extended first elastic airbags 304 can basically arrange the four anti-tilting multi-functional plates 3 around the goods stacked on the pallet respectively, which can ensure that the eight lock tongues 311 on the four anti-tilting multi-functional plates 3 are respectively inserted into the eight fork openings in the pallet, and the width of the opening between two adjacent anti-tilting multi-functional plates 3 is less than the size of the packaging carton of the hoisted goods, that is, the four anti-tilting multi-functional plates 3 can surround the goods on the pallet, effectively avoiding the scattering of the goods on the pallet.

[0042] Refer to Figure 4As shown, the anti-tipping multi-functional plate 3 includes a rectangular vertical plate 301, two locking tongues 311 for fastening the fork insertion openings in the tray, a driving source for pushing the locking tongues 311 to extend outwards, and four elastic bodies for automatically resetting and retracting the locking tongues 311. A high-definition camera is fixedly installed at the lower end of the rectangular vertical plate 301. The two locking tongues 311 are respectively installed horizontally and telescopically at both ends of the inner side of the lower end of the rectangular vertical plate 301. The thickness of the locking tongue 311 is less than the inner height of the fork insertion opening in the tray. The lower surface of the locking tongue 311 is provided with an inclined surface for guiding the locking tongue 311 to be inserted into the fork insertion opening. The driving source is arranged inside the rectangular vertical plate 301. The two ends of the elastic body are respectively connected to the rectangular vertical plate 301 and the locking tongue 311. A first vertical hole 302 is arranged in the middle of the rectangular vertical plate 301, and second vertical holes 303 are arranged on both sides. A sliding hole 310 is communicated with the bottom of the second vertical hole 303. The two locking tongues 311 respectively pass through the two sliding holes 310 telescopically.

[0043] Reference Figure 5 As shown, the elastic body is composed of a tension spring 313. Notches are arranged on both sides of the locking tongue 311. The end of the tension spring 313 is installed in the notch. A connecting block 312 is fixedly installed at the head of the tension spring 313. The connecting block 312 is fixedly connected to the rectangular vertical plate 301. The above-mentioned tension spring 313 is always in a stretched state and is used to automatically retract the locking tongue 311 along the sliding hole 310 into the bottom of the second vertical hole 303 by elastic force.

[0044] Reference Figure 4 As shown, the driving source is mainly composed of a multi-stage hydraulic cylinder 307, a pressing plate 308, two corrugated expansion tubes 309, two connecting tubes 306 and two second elastic air bags 314. The two second elastic air bags 314 are respectively arranged in a pressing manner on the back surfaces of the two locking tongues 311 in the anti-tipping multi-functional plate 3. The tops of the two second elastic air bags 314 are respectively communicated with the lower sides of the two connecting tubes 306. The two connecting tubes 306 are respectively communicated with the inner cavities at the lower ends of the two corrugated expansion tubes 309. The two ends of the pressing plate 308 are respectively arranged in a pressing manner on the tops of the two corrugated expansion tubes 309. The multi-stage hydraulic cylinder 307 is arranged in parallel between the two corrugated expansion tubes 309. The top of the multi-stage piston rod in the multi-stage hydraulic cylinder 307 is vertically connected to the lower side of the pressing plate 308;

[0045] The bottoms of the multi-stage hydraulic cylinder 307 and the two corrugated expansion tubes 309 are both fixedly connected to the inner bottom surface of the first vertical hole 302. The two connecting tubes 306 are respectively filled and arranged in the two second vertical holes 303. A plurality of rectangular holes 305 communicated with the second vertical holes 303 are arranged on the inner end surface of the rectangular vertical plate 301. First elastic air bags 304 are arranged in the rectangular holes 305. The first elastic air bags 304 are fixedly communicated with the connecting tubes 306. An anti-cutting pad is fixedly attached to the outer surface of the first elastic air bag 304. The anti-cutting pad is mainly used to protect the outer surface of the first elastic air bag 304.

[0046] It should be noted that after the multi-stage piston rod in the multi-stage hydraulic cylinder 307 contracts downward, it is used to drive the extrusion plate 308 to compress the gas in the two corrugated expansion tubes 309, and convey it to the two connecting tubes 306 respectively, generating high pressure in the two connecting tubes 306, and respectively transmitting and conveying it to a plurality of first elastic air bags 304 and two second elastic air bags 314. The expanded first elastic air bags 304 are used to squeeze and hold the goods therein, and the expanded second elastic air bags 314 are used to push the lock tongue 311 to extend out along the sliding hole 310 and snap into the fork inlet in the tray.

[0047] In this embodiment, an electric control box 2 is fixedly installed on the square frame plate 4. A storage battery, a programmable logic controller and a biaxial inclination sensor are fixedly installed in the electric control box 2. A tension sensor is fixedly connected between the top of the multi-stage piston rod in the multi-stage hydraulic cylinder 307 and the extrusion plate 308. The tension monitored in real time by the tension sensor is used to feedback the gas pressure in the inner cavities of the two corrugated expansion tubes 309. Since the two corrugated expansion tubes 309 are respectively communicated with a plurality of first elastic air bags 304 through the two connecting tubes 306 and the internal gas is interconnected, the internal gas pressure of the plurality of first elastic air bags 304 can be indirectly known, and thus the extrusion and clamping force between the plurality of first elastic air bags 304 and the goods in contact can be known. When the extrusion and clamping force between the plurality of first elastic air bags 304 and the hoisted goods is reached, the above-mentioned tension sensor is connected to the programmable logic controller through a wire for signal connection, timely feedbacks the extrusion and clamping force received by the first elastic air bag 304 to the programmable logic controller, and issues a stop command to the solenoid valve that controls the expansion and contraction of the multi-stage piston rod in the multi-stage hydraulic cylinder 307, that is, the solenoid valve that controls the expansion and contraction of the multi-stage piston rod in the multi-stage hydraulic cylinder 307 is connected to the programmable logic controller through a wire.

[0048] Reference Figures 1 - 2As shown in the figure, a cross-shaped center-of-gravity balancing mechanism 1 is installed on the electric control box 2. The cross-shaped center-of-gravity balancing mechanism 1 is suspended below the hook and is mainly composed of a cross module. The cross module can be adjusted in the X-axis and Y-axis directions to ensure the stability of the center of gravity of the pallet and the stacked goods above it during the hoisting process. The cross module is composed of a first linear module 102 and a second linear module 103. The guide rail in the first linear module 102 is fixedly connected above the slider in the second linear module 103. The guide rail in the second linear module 103 is fixedly embedded and installed on the electric control box 2. The guide rail in the first linear module 102 is slidably connected to the upper surface of the electric control box 2. The cross-shaped center-of-gravity balancing mechanism 1 further includes a connecting ring 101 for connecting the hook. The lower end of the connecting ring 101 is fixedly installed on the slider in the first linear module 102. The battery, programmable logic controller, biaxial inclination sensor, first linear module 102 and second linear module 103 are interconnected by wires;

[0049] When the pallet is lifted, due to the uneven weight of the goods stacked on the pallet, the pallet may tilt during lifting. The biaxial inclination sensor is used to monitor in real time whether the square frame plate 4 tilts in the X-axis and Y-axis directions. If the biaxial inclination sensor detects that the square frame plate 4 tilts in the X-axis or Y-axis direction, the biaxial inclination sensor will promptly feedback to the programmable logic controller for analysis and control the first linear module 102 or the second linear module 103 to perform motion adjustment in the X-axis or Y-axis direction to ensure the stability of the center of gravity of the pallet and the stacked goods above it during the hoisting process.

[0050] In this embodiment, the working process of the hoisting type loading and unloading device based on e-commerce goods in the port operation scenario is as follows:

[0051] 1). Preparation stage:

[0052] At the port operation site, determine the e-commerce goods stacked on the standard pallet to be hoisted. The operator starts the inspection process of each component of the hoisting type loading and unloading device in the remote control room with the help of the remote control system of the port container crane, covering the hook, square frame plate 4, anti-tilt multi-functional plate 3, electric control box 2, cross-shaped center-of-gravity balancing mechanism 1, etc., to ensure that all components are in normal operation. At the same time, the operator carefully observes the placement position of the goods and the pallet and the surrounding operation environment through the monitoring screen of the remote control system and plans the subsequent lifting route.

[0053] 2). Positioning before hoisting:

[0054] The operator is in the remote control room and uses the remote control system of the port container crane to control the movement of the crane, so that the hoisting type loading and unloading device moves above the goods. Through the high-definition camera equipped with the control system, the positions of the goods and the pallet are accurately observed, and the position of the crane is finely adjusted to ensure that the four anti-tipping multi-functional plates 3 are accurately aligned with the four sides of the pallet, making full preparations for grasping the goods.

[0055] 3). The locking tongue 311 is inserted into the fork inlet:

[0056] On the remote control system, the operator issues an instruction to start the multi-stage hydraulic cylinder 307. The multi-stage piston rod of the multi-stage hydraulic cylinder 307 contracts downward, driving the pressing plate 308 to compress the gas in the two corrugated expansion tubes 309. The gas is respectively transported to the two connecting tubes 306, generating high pressure in the two connecting tubes 306 and respectively transmitting and transporting it to a number of first elastic air bags 304 and two second elastic air bags 314. The expanded second elastic air bag 314 pushes the locking tongue 311 to extend along the sliding hole 310 and insert into the fork inlet in the pallet. The inclined surface on the lower surface of the locking tongue 311 helps to guide it to quickly insert into the fork inlet.

[0057] 4). Adjust the clamping force:

[0058] The pulling force of the multi-stage piston rod in the multi-stage hydraulic cylinder 307 is monitored in real time through the tension sensor, so as to indirectly know the internal gas pressure of the first elastic air bag 304 and the extrusion clamping force with the goods. When the preset extrusion clamping force is reached, the programmable logic controller controls the multi-stage hydraulic cylinder 307 to stop working to ensure that the clamping force is appropriate.

[0059] 5). Increase the clamping stability:

[0060] A number of first elastic air bags 304 on the inner end faces of the four anti-tipping multi-functional plates 3 expand and extend outwards, pressing the two vacuum suction cups 316 outside the first elastic air bag 304 against and sealing on the surface of the hoisted goods or the surface of the film wound around the goods. Then, the programmable logic controller turns on the vacuum pump, and the air in the eight negative pressure tubes 318 is extracted in turn through the air extraction inlets of the vacuum pump by eight air extraction tubes 319, making the several vacuum suction cups 316 generate negative pressure and further increasing the clamping force between the goods and the inner side of the anti-tipping multi-functional plate 3.

[0061] 6). Ensure the center of gravity is stable:

[0062] The biaxial inclination sensor monitors in real time whether the square rack board 4 tilts in the X-axis and Y-axis directions. If it detects that the square rack board 4 tilts, the biaxial inclination sensor will promptly feedback the signal to the programmable logic controller for analysis, and then control the first linear module 102 or the second linear module 103 in the cross-shaped center-of-gravity balance mechanism 1 to move and adjust in the X-axis or Y-axis direction to ensure the stability of the center of gravity of the tray and the stacked goods above during the lifting process.

[0063] 7). Completing the lifting:

[0064] After confirming that the goods are stably grasped and the center of gravity is stable, the operator controls the crane through the remote control system of the port container crane to lift the goods along the planned lifting route and transport them to the designated position. When the goods are lifted above the target position, the operator sends an instruction on the remote control system to control the multi-stage hydraulic cylinder 307 to work in the reverse direction. The multi-stage piston rod extends upward, the extrusion plate 308 rises, the gas pressure in the first elastic airbag 304 and the second elastic airbag 314 decreases, and the locking tongue 311 retracts under the action of the tension spring 313, disengaging from the tray fork inlet. The first elastic airbag 304 contracts and separates from the surface of the goods. Finally, the operator controls the crane to slowly lower and place the goods safely and accurately at the designated position, thus completing the loading or unloading operation of the tray and its goods.

[0065] Embodiment 2:

[0066] Based on Embodiment 1, the main difference between Embodiment 2 and Embodiment 1 is that one or two vacuum suction cups 316 are installed on the outer surface of each first elastic airbag 304, preferably two vacuum suction cups 316, and the outer surface of the first elastic airbag 304 may not be adhesively connected with a cut-resistant pad.

[0067] As Figures 6 - 7 shown, a steel pad 315 is fixedly installed between the backs of the two vacuum suction cups 316. The steel pad 315 and the outer surface of the first elastic airbag 304 are mutually attached. The air inlets of the vacuum suction cups 316 are respectively sealed and penetrate into the first elastic airbag 304, and are fixedly connected with a round tube 317. The end of the round tube 317 is arranged in the inner cavity of the connecting tube 306, and a negative pressure tube 318 is fixedly installed in the connecting tube 306. The end of the negative pressure tube 318 and all the round tubes 317 in the connecting tube 306 are fixedly connected. The top of the negative pressure tube 318 is fixedly connected with an air extraction tube 319. The eight air extraction tubes 319 in the four anti-tilting multifunctional plates 3 are connected to a vacuum pump through a high-pressure tube for fixedly connecting the air extraction inlet of the vacuum pump and the openings of the eight air extraction tubes 319.

[0068] It should be added that the vacuum pump is connected to the storage battery and the programmable logic controller in the electric control box 2 through a wire. After the preset extrusion clamping force is reached between the first elastic airbag 304 in Embodiment 1 and the hoisted goods, that is, several first elastic airbags 304 expand and extend outwards, and the two vacuum suction cups 316 outside the first elastic airbag 304 are attached, sealed and extruded on the surface of the hoisted goods or the surface of the film wound around the periphery of the goods. Then, the vacuum pump can be turned on through the programmable logic controller, and the air in the eight negative pressure tubes 318 is extracted in sequence through the eight air extraction tubes 319 from the air extraction inlet of the vacuum pump, creating a negative pressure space in the eight negative pressure tubes 318, so that a number of vacuum suction cups 316 connected to the negative pressure tubes 318 generate negative pressure, increasing the clamping force between the hoisted goods and the inner side of the anti-tilting multifunctional plate 3, effectively avoiding the slipping phenomenon between the hoisted goods and the anti-tilting multifunctional plate 3, making the clamping more stable and the hoisting safer.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
