Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, and in particular to an automatic loading and unloading device for cargo transportation. Background Technology

[0002] Freight transportation is a crucial link in modern economic activities, responsible for transporting various goods from production sites to consumption sites. It encompasses multiple modes, including road transport, rail transport, water transport, and air transport. In the context of globalized trade, the scale and frequency of freight transportation are constantly increasing, and the requirements for transportation efficiency and quality are also rising. Whether it is raw materials, components, or finished goods, precise and rapid transportation is needed to meet market demands and promote economic development and social operation.

[0003] In particular, road freight transport has become an important mode of goods distribution due to its flexibility and convenience. In road transport, the loading and unloading process of trucks directly affects the overall efficiency and cost of transportation. Most ordinary goods are placed in the truck bed and stacked from the bottom to make full use of the space.

[0004] Existing truck loading and unloading has improved efficiency to some extent by using forklifts or cranes, avoiding the inefficient situation of relying entirely on manual labor to move goods one by one onto the truck. However, these devices are expensive, and loading and unloading sites cannot guarantee that they will all have them. Moreover, these devices are large and cannot be carried with the truck. Without these devices, manual operation is still highly dependent on manual labor. During assembly, goods at lower levels need to be moved to higher levels, and during unloading, goods at higher levels need to be moved to lower levels. This process is not only extremely labor-intensive, but also prone to damage to goods due to fatigue or improper operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic loading and unloading device for cargo transportation, which aims to improve the problem that the existing technology still relies heavily on manual operation due to the high cost of the equipment and its large size, which makes it impossible to carry it with the vehicle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic loading and unloading device for cargo transportation, comprising a mounting base plate, a fixed cylinder fixedly connected to the top of the mounting base plate, a rotating column rotatably connected inside the fixed cylinder, a crossbeam fixedly connected to the top of the rotating column, an L-shaped carrier plate fixedly connected to the upper middle part of the outer wall of the fixed cylinder, the top left side of the L-shaped carrier plate fixedly connected to the bottom left side of the crossbeam, a winding machine fixedly installed on the top right side of the L-shaped carrier plate, a steel rope installed inside the winding machine, a fixed pulley fixedly installed at the bottom left end of the crossbeam, the end of the steel rope passing through the left side of the L-shaped carrier plate and fixed to the bottom end of the fixed pulley, a movable pulley provided at the bottom of the fixed pulley, the middle part of the steel rope located inside the movable pulley, a rotating connector fixedly installed at the bottom end of the movable pulley, and a cargo mounting mechanism provided at the bottom of the rotating connector, the cargo mounting mechanism being used to connect and mount cargo.

[0009] As a further description of the above technical solution:

[0010] A nylon suspension rope is fixedly connected to the bottom right end of the crossbeam, and a load-bearing plate is fixedly connected to the bottom end of the nylon suspension rope. Multiple counterweights are provided on the top of the load-bearing plate.

[0021] This utility model has the following beneficial effects:

[0022] 1.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an automatic loading and unloading device for cargo transportation, comprising a mounting base plate 1, a fixed cylinder 3 fixedly connected to the top of the mounting base plate 1, a rotating column 4 rotatably connected inside the fixed cylinder 3, a crossbeam 5 fixedly connected to the top of the rotating column 4, an L-shaped carrier plate 6 fixedly connected to the upper middle part of the outer wall of the fixed cylinder 3, the top left side of the L-shaped carrier plate 6 fixedly connected to the bottom left side of the crossbeam 5, a winding machine 7 fixedly installed on the top right side of the L-shaped carrier plate 6, a steel rope 8 disposed inside the winding machine 7, a fixed pulley 9 fixedly installed at the bottom left end of the crossbeam 5, the end of the steel rope 8 passing through the left side of the L-shaped carrier plate 6 and fixed to the bottom end of the fixed pulley 9, a movable pulley 10 disposed at the bottom of the fixed pulley 9, the middle part of the steel rope 8 disposed inside the movable pulley 10, a rotating connector 11 fixedly installed at the bottom end of the movable pulley 10, and a cargo hanging mechanism 2 disposed at the bottom of the rotating connector 11, the cargo hanging mechanism 2 being used to connect and hang cargo.

[0033] Specifically, the mounting base plate 1 ensures that the equipment will not shake or shift during loading and unloading. The fixed cylinder 3 at its top serves as a support structure, and the rotating column 4 inside it can rotate flexibly. The top of the rotating column 4 is fixedly connected to the crossbeam 5. By rotating the column 4, the crossbeam 5 can be adjusted horizontally, thus better adapting to the loading and unloading needs of different positions. The L-shaped carrier plate 6 provides additional support for the crossbeam 5, enhancing structural stability. Simultaneously, the winding machine 7 fixedly installed on its top right side serves as a power source. The internal steel rope 8 is wound and unwound under the action of the winding machine 7. The end of the steel rope 8 passes through the left side of the L-shaped carrier plate 6 and changes direction through the fixed pulley 9. The fixed pulley 9 is fixed to the bottom left end of the crossbeam 5, and its function is to guide the movement direction of the steel rope 8, enabling the steel rope 8 to smoothly transmit force. The middle part of the steel rope 8 is located at the movable pulley. Inside the pulley 10, the movable pulley 10 can move up and down with the movement of the steel rope 8. The rotating connector 11 fixedly installed at the bottom of the movable pulley 10 increases the flexibility of loading and unloading goods. When loading and unloading goods is required, the winding machine 7 starts to work and releases the steel rope 8. Under the action of gravity, the movable pulley 10 moves downward with the rotating connector 11 and the cargo mounting mechanism 2 until the cargo mounting mechanism 2 reaches the position of the goods. Then the goods are fixed on the cargo mounting mechanism 2. Then the winding machine 7 rotates in the opposite direction and starts to wind up the steel rope 8. At this time, the steel rope 8 lifts the goods upward through the combined action of the fixed pulley 9 and the movable pulley 10. During the lifting process, the rotating column 4 can adjust the angle of the crossbeam 5 as needed to accurately lift the goods to the designated position. In the whole process of loading and unloading goods, automatic loading and unloading of goods is realized, which greatly improves work efficiency and reduces the intensity of manual labor.

[0034] Reference Figure 1 and Figure 4 The cargo mounting mechanism 2 includes multiple upper connecting ropes 201. The top ends of the multiple upper connecting ropes 201 are fixedly connected to the inside of the rotating connecting member 11. The bottom ends of the multiple upper connecting ropes 201 are fixedly connected to the fixing connecting member 202. The bottom ends of the multiple fixing connecting members 202 are fixedly connected to the lower connecting ropes 203. The bottom ends of the multiple lower connecting ropes 203 are fixedly connected to the safety buckles 204. The inside of the multiple safety buckles 204 is fixedly installed with buckle pieces 205. X-shaped support rods 206 are fixedly connected between adjacent fixed connecting members 202.

[0035] Specifically, the top ends of multiple upper connecting ropes 201 in the cargo mounting mechanism 2 are fixedly connected to the interior of the rotating connecting member 11 to transmit force and bear the weight of the cargo. The upper connecting ropes 201 can withstand large tensile forces to ensure that they will not break during hoisting. The fixed connecting members 202 fixedly connected to the bottom ends of the upper connecting ropes 201 play the role of connecting and distributing the force. They evenly transmit the tensile force from the upper connecting ropes 201 to the lower connecting ropes 203, and also provide a fixing point for the X-shaped support rod 206. The lower connecting ropes 203 also have good tensile strength. The safety buckle 204 fixedly connected to its bottom end is used to directly contact and fix the cargo. The buckle piece 205 fixedly installed inside the safety buckle 204 can firmly hold the cargo and prevent the cargo from falling off during hoisting. When it is necessary to hoist the cargo, the rotating connecting member 11 is lowered by the winding machine 7. The upper connecting rope 201, fixed connecting piece 202, lower connecting rope 203, and safety buckle 204 are lowered together to the location of the goods. The staff fastens the safety buckle 204 to the appropriate position of the goods and ensures that the buckle piece 205 is locked in place. Then the winding machine 7 starts to lift, and the rotating connecting piece 11 is subjected to an upward pulling force. The pulling force is transmitted to the fixed connecting piece 202 through the upper connecting rope 201. The fixed connecting piece 202 evenly distributes the pulling force to each lower connecting rope 203. The lower connecting rope 203 then steadily lifts the goods through the safety buckle 204 and the buckle piece 205. During the lifting process, the X-shaped support rod 206 fixedly connected between multiple fixed connecting pieces 202 can enhance the structural stability of the entire goods hanging mechanism 2 and prevent the goods hanging mechanism 2 from deforming or twisting during the lifting process, thereby ensuring that the goods can be lifted to the designated position smoothly and safely.

[0036] Reference Figure 1 , Figure 3 and Figure 5 A nylon suspension rope 12 is fixedly connected to the bottom right end of the crossbeam 5. A load-bearing plate 13 is fixedly connected to the bottom end of the nylon suspension rope 12. Multiple counterweights 14 are set on the top of the load-bearing plate 13. The front side of each counterweight 14 is provided with a groove 15, and the interior of each groove 15 is designed to be smooth. A V-shaped bracket 16 is fixedly connected to the front end of the bottom wall of the L-shaped carrier plate 6. A handle 17 is fixedly connected to the front end of the bottom of the V-shaped bracket 16. An installation ring 18 is fixedly connected to the middle of the outer wall of the rotating column 4. An auxiliary support rod 19 is fixedly connected to the front side of the installation ring 18. The front end of the auxiliary support rod 19 is fixedly connected to the rear end of the handle 17. An anti-slip sleeve 20 is fixedly connected to the outer wall of the handle 17. The outer wall of the anti-slip sleeve 20 is made of frosted material. Mounting bolts 21 are fixedly connected through and fixedly connected to the four corners of the top of the mounting base plate 1. The bottom of the outer wall of each mounting bolt 21 is designed to be anti-slip.

[0037] Specifically, the nylon lifting rope 12, fixedly connected to the bottom right end of the crossbeam 5, has high strength and flexibility. The bottom end of the nylon lifting rope 12 is fixedly connected to a load-bearing plate 13, which supports multiple counterweights 14. The counterweights 14 increase the weight at the bottom of the equipment, improving overall stability, especially when lifting heavy loads, preventing the equipment from tilting or swaying due to an unstable center of gravity. The groove 15 on the front side of the counterweight 14 has a smooth internal design, facilitating the operator's handling and adjustment of the counterweight 14's position. The V-shaped bracket 16, fixedly connected to the front end of the bottom wall of the L-shaped carrier plate 6, provides support and connection. The handle 17, fixedly connected to the front side of the bottom end of the V-shaped bracket 16, provides the operator with a manual control and operation point. The anti-slip sleeve 20, fixedly connected to the outer wall of the handle 17, uses a frosted finish to increase the friction between the hand and the handle 17, allowing the operator to grip the handle 17 more firmly for precise operation. The mounting ring 18, fixedly connected to the middle of the outer wall of the rotating column 4, has a fixed front side... The fixed connection of the auxiliary support rod 19 further enhances the stability of the structure. The front end of the auxiliary support rod 19 is fixedly connected to the rear end of the handle 17, which effectively distributes the force and reduces the burden on the V-shaped bracket 16, ensuring that the handle 17 can withstand greater force without deformation or damage during operation. The mounting bolts 21, which are fixedly connected through the four corners of the top of the mounting base plate 1, have an anti-slip design on the bottom of their outer wall, which can firmly fix the equipment to the ground or transport vehicle. When loading and unloading goods, it ensures that the equipment will not move due to vibration or external force, ensuring the safety and accuracy of operation. When loading and unloading goods, the equipment is first fixedly installed in a suitable position by the mounting bolts 21. According to the weight of the goods and the lifting requirements, the number and distribution of the counterweights 14 on the load-bearing plate 13 are adjusted to achieve the best center of gravity balance. The operator holds the handle 17 with the anti-slip sleeve 20 and adjusts the angle and position of the crossbeam 5 by controlling the rotation of the rotating column 4, so that the cargo mounting mechanism 2 is accurately aligned with the goods.

[0038] Working Principle: The mounting base plate 1 ensures that the equipment will not shake or shift during loading and unloading. The fixed cylinder 3 at its top serves as a support structure, and the rotating column 4 inside it can rotate flexibly. The top of the rotating column 4 is fixedly connected to the crossbeam 5. By rotating the rotating column 4, the crossbeam 5 can be adjusted horizontally, thus better adapting to the loading and unloading needs of different positions. The L-shaped carrier plate 6 provides additional support for the crossbeam 5, enhancing the stability of the structure. Simultaneously, the winding machine 7 fixedly installed on its top right side serves as the power source. The internal steel rope 8 is wound and unwound under the action of the winding machine 7. The end of the steel rope 8 passes through the left side of the L-shaped carrier plate 6 and changes direction through the fixed pulley 9. The fixed pulley 9 is fixed to the bottom left end of the crossbeam 5, and its function is to guide the movement direction of the steel rope 8. The steel rope 8 is designed to transmit power smoothly. The middle part of the steel rope 8 is located inside the movable pulley 10. The movable pulley 10 can move up and down with the movement of the steel rope 8. The rotating connector 11 fixedly installed at the bottom of the movable pulley 10 increases the flexibility of loading and unloading goods. When loading and unloading goods is required, the winding machine 7 starts to work and releases the steel rope 8. Under the action of gravity, the movable pulley 10 moves downward with the rotating connector 11 and the cargo mounting mechanism 2 until the cargo mounting mechanism 2 reaches the location of the goods. Then the goods are fixed on the cargo mounting mechanism 2. Then the winding machine 7 rotates in the opposite direction and starts to wind up the steel rope 8. At this time, the steel rope 8 lifts the goods upward through the combined action of the fixed pulley 9 and the movable pulley 10. During the lifting process, the rotating column 4 can adjust the angle of the crossbeam 5 as needed to accurately lift the goods to the designated position.

[0039] Furthermore, the top ends of multiple upper connecting ropes 201 in the cargo mounting mechanism 2 are fixedly connected to the interior of the rotating connecting member 11 to transmit force and bear the weight of the cargo. The upper connecting ropes 201 can withstand large tensile forces, ensuring that they will not break during hoisting. The fixed connecting members 202 fixedly connected to the bottom ends of the upper connecting ropes 201 play the role of connecting and distributing the force. They evenly transmit the tensile force from the upper connecting ropes 201 to the lower connecting ropes 203, and also provide a fixing point for the X-shaped support rod 206. The lower connecting ropes 203 also have good tensile strength. The safety buckle 204 fixedly connected to its bottom end is used to directly contact and fix the cargo. The buckle piece 205 fixedly installed inside the safety buckle 204 can firmly hold the cargo and prevent the cargo from falling off during hoisting. When hoisting goods, the rotating connector 11 is lowered by the rewinder 7, which drives the upper connecting rope 201, the fixed connector 202, the lower connecting rope 203 and the safety buckle 204 to the position of the goods. The staff fastens the safety buckle 204 in the appropriate position of the goods and ensures that the buckle piece 205 is locked in place. Then the rewinder 7 starts to lift, and the rotating connector 11 is subjected to an upward pull. The pull is transmitted to the fixed connector 202 through the upper connecting rope 201. The fixed connector 202 evenly distributes the pull to each lower connecting rope 203. The lower connecting ropes 203 then steadily lift the goods through the safety buckle 204 and the buckle piece 205. During the hoisting process, the X-shaped support rod 206 fixedly connected between the multiple fixed connectors 202 can enhance the structural stability of the entire goods hoisting mechanism 2.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
