Description

Technical Field

[0001] The invention belongs to the technical field of logistics equipment, and in particular, relates to a lifting device for a logistics supply chain. Background Art

[0002] As a key carrier of standardization and unitization in logistics transportation, containers are widely used in various modes of transportation such as sea, land and air transportation because of their good sealing, high strength and easy mechanized operation. By integrating various types of goods in containers, the rapid loading, unloading, transshipment and storage of goods are achieved, greatly improving the overall efficiency of the logistics supply chain.

[0003] In many links of the logistics supply chain, lifting equipment plays an indispensable role. Whether it is lifting containers from cargo ships at port terminals and transferring them to storage yards, or loading and unloading containers at factory warehouses, lifting equipment is the core tool for realizing vertical displacement and horizontal transportation of goods. It can quickly and accurately place containers at designated locations to ensure the smooth progress of the logistics process. However, there are many defects in the lifting equipment currently on the market that need to be solved;

[0004] For example, the traditional lifting method only relies on a single connection or adsorption method. When encountering a complex lifting environment, such as strong winds, shaking lifting equipment, etc., the container is prone to shaking, tilting or even falling off, which not only poses a threat to the safety of the goods, but may also cause serious safety accidents, resulting in casualties and property losses. Moreover, due to the lack of additional support structure for the container, during the lifting process, the force distribution of the container itself is uneven, which can easily lead to damage to the container, reduce the service life of the container, and further increase logistics costs. In view of this, the present invention is specially proposed. Summary of the invention

[0012] Preferably, a plurality of groups of electromagnets are fixedly mounted on the lower end surface of the mounting frame, and each group of electromagnets is provided with a plurality of electromagnets which are equidistantly distributed on the lower end surface of the mounting frame.

[0014] In order to clean the particulate impurities on the surface of the hoisted objects, so that the installation frame can stably hoist the objects through the electromagnet, further, a sliding cavity is provided on the installation frame, and a piston disk 2 is slidably connected in the sliding cavity, and a push rod is fixedly connected to the piston disk 2.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0030] Example 1: Reference Figure 1 , Figure 2 , Figure 4 , Figure 6A lifting device for a logistics supply chain includes a mounting frame 1 connected to the output end of a robotic arm, and also includes: fixed plates 202 are symmetrically arranged and are both slidably connected to the mounting frame 1; a driving unit is arranged on the mounting frame 1 and is used to drive the fixed plate 202 to move; a sliding box 3 is connected to the lower end of the fixed plate 202, wherein a sliding rod 307 is fixedly connected to the sliding box 3, a hollow cavity 304 is opened in the lower end of the fixed plate 202, a counterweight slider 305 is slidably connected in the hollow cavity 304, and one end of the sliding rod 307 passes through the hollow cavity 304 and is fixedly connected to the counterweight slider 305; a piston plate 301 is slidably connected in the sliding box 3; a bearing plate 302 is fixedly connected to the piston plate 301; an air supply pipe 403 is fixedly connected to the sliding box 3, and is used to supply air to the sliding box 3 from an external air source, and push the piston plate 301 to drive the bearing plate 302 to move out of the sliding box 3.

[0031] The driving unit includes a bidirectional screw rod 2 and a guide groove 201 opened on both ends of the lower end of the mounting frame 1. The fixed plate 202 is slidably connected in the guide groove 201 and is threadedly connected to the bidirectional screw rod 2. A motor 203 is fixedly installed on the mounting frame 1, and the bidirectional screw rod 2 is fixedly connected to the output end of the motor 203.

[0032] A spring 1 306 is disposed in the hollow cavity 304 , and the spring 1 306 is located between the top surface of the hollow cavity 304 and the counterweight slider 305 .

[0033] When in use, the mechanical arm first drives the mounting frame 1 to move above the container, at which time the two fixing plates 202 are respectively located on both sides of the container, and then the motor 203 is started, the motor 203 drives the bidirectional screw rod 2 to rotate, and the bidirectional screw rod 2 drives the fixing plates 202 threadedly connected thereto to slide toward each other in the guide slide groove 201 until the fixing plates 202 abut against the side walls of the container, thereby clamping and fixing the container. At the same time, the fixing plates 202 can be moved closer or farther away by the forward and reverse rotation of the motor 203, thereby adjusting the distance between the two fixing plates 202 to adapt to the clamping and fixing of containers of different sizes, thereby improving the versatility of the lifting device.

[0034] At the same time, when the installation frame 1 moves downward to approach the container, the lower end surface of the sliding box 3 first contacts the ground. As the installation frame 1 continues to move downward, the sliding box 3 will push the counterweight slider 305 to slide upward in the hollow cavity 304 through the sliding rod 307. During this process, the spring 1 306 is compressed to store elastic potential energy. Then, when the container is successfully lifted off the ground, the previously compressed spring 1 306 releases its elastic potential energy, pushing the counterweight slider 305 to move downward, thereby driving the sliding box 3 to reset downward. At this time, the load-bearing plate 305 originally retracted in the sliding box 3 is 02 will be in a parallel state with the lower surface of the container, preparing for the subsequent extension of the load-bearing plate 302 to receive the container. Then, the external gas source supplies gas to the sliding box 3 through the gas pipe 403. After the gas enters the sliding box 3, air pressure will be formed in the box, pushing the piston plate 301 to slide in the sliding box 3. The piston plate 301 is fixedly connected to the load-bearing plate 302, so the load-bearing plate 302 will move out of the sliding box 3 with the movement of the piston plate 301 and contact with the lower surface of the container, so that it provides additional support for the container, further enhancing the stability of the container during the lifting process.

[0035] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 A lifting device for a logistics supply chain is basically the same as Example 1. Furthermore, a plurality of groups of electromagnets 5 are fixedly mounted on the lower end surface of the mounting frame 1, and each group of electromagnets 5 is provided with a plurality of electromagnets 5 that are equidistantly distributed on the lower end surface of the mounting frame 1.

[0036] A sliding cavity 6 is provided on the mounting frame 1, in which a piston disk 2 601 is slidably connected, a push rod 603 is fixedly connected to the piston disk 2 601, and a hollow box 604 is fixedly installed on one end of the push rod 603 that passes through the sliding cavity 6. The hollow box 604 is located below the lower end surface of the mounting frame 1, and a plurality of obliquely arranged jet holes 607 are provided on both sides of the hollow box 604. A spring 2 602 is provided in the sliding cavity 6 and is located between the top surface of the sliding cavity 6 and the piston disk 2 601. A conduit 1 605 and a conduit 2 606 that are connected to the sliding cavity 6 are provided on the mounting frame 1, and the sliding cavity 6 is connected to the hollow box 604 through the conduit 2 606.

[0037] In the process of the installation frame 1 moving downward and approaching the container, the hollow box 604 takes the lead in playing a role, and the lower end surface of the hollow box 604 will first contact the upper surface of the container. As the installation frame 1 continues to move downward, the hollow box 604 is squeezed, and the piston plate 2 601 is pushed to slide upward in the sliding chamber 6 through the push rod 603. In this process, the spring 2 602 is compressed to store elastic potential energy. The upward movement of the piston plate 2 601 changes the spatial volume in the sliding chamber 6, so that the gas in the chamber is compressed. According to the gas pressure principle, the pressure of the gas increases when the volume decreases. The compressed gas is transported to the jet hole 607 through the second conduit 606. Since the jet hole 607 is inclined, when the gas is ejected from the jet hole 607, it will impact the surface of the container at a certain angle, which can not only clean the dust and debris on the surface of the container, ensuring that the subsequent electromagnet 5 can have good contact with the surface of the container and improve the adsorption effect, but also can use the impact force of the airflow to play a certain positioning and fine-tuning role on the container, helping the operator to more accurately align the installation frame 1 with the container, and ensure the accuracy of the entire lifting operation;

[0038] When the installation frame 1 continues to move downward until the electromagnet 5 on the installation frame 1 contacts the upper surface of the container, at this time, the electromagnet 5 is energized. Since the container is usually made of ferromagnetic material, the container will be firmly adsorbed by the electromagnet 5 under the action of the magnetic field. Among them, multiple groups of electromagnets 5 with equal distances greatly increase the adsorption area with the container, so that the adsorption force is evenly distributed on the upper surface of the container, ensuring that the container can be stably fixed under the installation frame 1 during the lifting process, thereby improving the safety of the lifting operation.

[0039] After the container is hoisted to a suitable position, the motor 203 is started, and the output end of the motor 203 drives the bidirectional screw 2 to rotate in the opposite direction. Since the fixing plate 202 is threadedly connected to the bidirectional screw 2, and the guide slot 201 plays a guiding role, the fixing plate 202 slides in the guide slot 201 to the side away from the container, and the fixing plate 202 releases the clamping of the container. During the movement of the fixing plate 202, since it is connected to the sliding box 3, it will drive the sliding box 3 to move together, so that the carrying plate 302 is separated from the container, and then the electromagnet 5 is turned off to make it lose its magnetic attraction to the container, thereby completing the entire operation of lowering the container;

[0040] When the mounting frame 1 moves away from the container driven by the robotic arm, the compressed spring 2 602 releases elastic potential energy, pushing the piston disc 2 601 to move downward in the sliding chamber 6. During the downward movement of the piston disc 2 601, external gas can be absorbed into the sliding chamber 6 through the conduit 1 605, thereby preparing for subsequent lifting operations.

[0041] It should be noted that one-way valves are provided on both conduit 1 605 and conduit 2 606;

[0042] The second conduit 606 is a stretchable and shrinkable hose, so the second conduit 606 will not interfere with the movement of the hollow box 604.

[0043] Example 3: Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 A lifting device for a logistics supply chain is basically the same as Example 1. Furthermore, a sleeve 4 is fixedly connected to the mounting frame 1, a piston disc 401 is slidably connected in the sleeve 4, a connecting rod 402 is fixedly connected to the piston disc 401, one end of the connecting rod 402 passes through the sleeve 4 and is fixedly connected to the fixed plate 202, and an end of the air pipe 403 away from the sliding box 3 is connected to the sleeve 4.

[0044] It also includes a solenoid valve 404 for controlling the switch of the gas pipe 403 , and the solenoid valve 404 is arranged on the gas pipe 403 .

[0045] It also includes a tension spring 303 arranged in the sliding box 3 , one end of the tension spring 303 is fixedly connected to the piston plate 301 , and the other end is fixedly connected to the inner wall of the sliding box 3 .

[0046] It also includes a conductive ring 1 501 and a conductive ring 2 502 for controlling the switch of the electromagnet 5. The conductive ring 1 501 is fixedly installed on the piston plate 301, and the conductive ring 2 502 is fixedly installed on the inner wall of the sliding box 3 near the opening side.

[0047] When the fixed plate 202 moves toward the side close to the container, the connecting rod 402 can push the piston disc 1 401 to move synchronously toward the side close to the container in the sleeve 4. The movement of the piston disc 1 401 changes the volume of the space in the sleeve 4, so that the gas in the cavity is compressed. According to the gas pressure principle, the pressure of the gas increases when the volume decreases. When the fixed plate 202 is against the side wall of the container, the solenoid valve 404 on the gas pipe 403 is opened. At this time, the compressed gas can be transported to the sliding box 3 through the gas pipe 403. After the gas enters the sliding box 3, air pressure is formed in the box, pushing the piston plate 301 to drive the bearing plate 302 to move out of the sliding box 3 and stretching the tension spring 303. When the piston plate 301 drives the bearing plate 302 to move out of the sliding box 3, the conductive ring 1 501 on the piston plate 301 contacts the conductive ring 2 502 on the inner wall of the sliding box 3, the circuit is connected, and the electromagnet 5 is energized to generate magnetic attraction.

[0048] When the fixed plate 202 moves to the side away from the container, the connecting rod 402 can push the piston plate 1 401 to move synchronously to the side away from the container in the sleeve 4. At this time, the gas compressed into the sliding box 3 can flow back into the sleeve 4 through the gas pipe 403. At the same time, as the air supply pressure of the gas source on the piston plate 301 disappears, the tension spring 303 starts to play a role, and the tension spring 303 contracts, driving the piston plate 301 and the bearing plate 302 to retract into the sliding box 3. When the piston plate 301 drives the bearing plate 302 to retract into the sliding box 3, the conductive ring 1 501 on the piston plate 301 is separated from the conductive ring 2 502 on the inner wall of the sliding box 3, the circuit is disconnected, and the electromagnet 5 is powered off and loses its magnetic attraction.

[0049] In summary, the design of controlling the on and off of the electromagnet 5 by moving the supporting plate 302 realizes automated operation, reduces manual intervention, and improves work efficiency. At the same time, it ensures that the electromagnet 5 is energized and adsorbed only when the supporting plate 302 is in contact with the container, avoiding accidental adsorption or other safety problems that may be caused by premature energization, thereby improving the safety of lifting operations.

[0050] It should be noted that the air supply pipe 403 is a stretchable and shrinkable hose, so the air supply pipe 403 will not interfere with the movement of the fixing plate 202 .

[0051] Example 4: Reference Figure 1 , Figure 2 , a lifting device for logistics supply chain, which is basically the same as embodiment 1, and further, a connecting seat 101 is fixedly installed on the mounting frame 1, the connecting seat 101 is arranged in an annular shape, and a plurality of mounting holes 102 are opened on the connecting seat 101 at equal intervals;

[0052] Through the mounting hole 102 on the connecting seat 101, the mounting frame 1 is fixedly connected to the output end of the robot arm using bolts or other connecting parts;

[0053] The connecting seat 101 is arranged in a ring shape, and the mounting holes 102 evenly distributed around the circumference provide multiple connection points. By passing the connecting parts through the mounting holes 102 and fastening them to the output end of the robot arm, a stable connection between the mounting frame 1 and the robot arm is achieved, ensuring that the robot arm can reliably drive the mounting frame 1 to perform lifting operations.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with a preferred embodiment, it is not used to limit the present invention.
