Description

Technical Field

[0001] The present invention relates to the technical field of port transportation, and specifically relates to a cargo loading and transportation device for port transportation and loading and unloading. Background Art

[0002] In port transportation, goods are often presented in the form of containers, which directly omits the unloading link at the port and realizes the function of directly docking with the factory destination for unloading, greatly increasing the cargo transportation efficiency at the port. A container is a semi-closed box structure made of metal, with goods loaded inside. For some goods, such as potatoes, sweet potatoes, etc. during transportation; When an unmanned vehicle transports a container and brakes, even if the running speed is slow, due to the excessive weight of the container and the goods, the potential energy generated by the movement is also correspondingly high. This causes the potential energy to be transmitted to the inside of the container during braking, resulting in the goods inside the container being dumped, thus causing damage to the goods. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a cargo loading and transportation device for port transportation and loading and unloading, including an unmanned vehicle; A transportation mechanism is arranged on the inner wall of the unmanned vehicle, and when in use, the container is placed on the top of the unmanned vehicle; A driving mechanism is rotatably arranged on the inner wall of the transportation mechanism, and is used to adjust the tilt angle of the container on the top when the unmanned vehicle brakes suddenly; A hydraulic mechanism is fixedly arranged on the side wall of the transportation mechanism, and is used to clamp and limit the outer wall of the container; Among them, before use, the container is first placed on the top of the unmanned vehicle. During the transportation of the unmanned vehicle, when sudden braking occurs, the driving mechanism will adjust the tilt angle of the container, and then the hydraulic mechanism will clamp the end of the container to limit the movement of the container.

[0004] Preferably, the transportation mechanism includes: An installation component is arranged on the inner wall of the unmanned vehicle, and is used to provide an installation space for the driving mechanism and the hydraulic mechanism; A load-bearing component is fixedly connected to the inner wall of the installation component through a connecting piece; The connecting piece includes a fixing column fixedly connected to the inner wall of the unmanned vehicle, and a bearing plate is rotatably connected to the outer wall of the fixing column; Among them, the container is placed on the top of the bearing plate, and the pressure received by the bearing plate will be transmitted to the unmanned vehicle; When the rotation angle of the bearing plate changes, the container on the top of the bearing plate will tilt synchronously, as Figure 6As shown, this change causes the pressure of the potential energy on the trolley to change from state G to state F, where the pressure of F is downward and inclined. At this time, it can be regarded that the pressure generated by the F potential energy is formed by two forces, one to the left and the other downward. Moreover, when the container and the internal items are subjected to the downward potential energy pressure, the contact pressure between the internal goods and the bottom goods will increase, improving the tightness of the contact between the upper and lower goods. The tightly fitted goods can effectively offset the lateral potential energy pressure and effectively reduce the phenomenon of the goods falling due to sudden braking.

[0005] Preferably, the driving mechanism includes: A driving component, which is fixedly arranged on the inner wall of the mounting component and is used to provide power for the adjustment of the device; A control component, which is slidably arranged on the inner wall of the mounting component and is used to change the driving force generated by the driving component into the inclination angle of the bearing plate; Among them, before the unmanned vehicle makes a sudden brake, the driving component quickly generates a driving force, forcing the control component to slide on the inner wall of the mounting component, forcing the bearing plate to move downward. Without changing the direction of the potential energy, the angle of the container is changed, and the potential energy forces the goods in the container to tilt synchronously, increasing the pressure between the goods.

[0006] Preferably, the hydraulic mechanism includes: A hydraulic component, which is fixedly arranged on the inner wall of the unmanned vehicle through a mounting piece; The mounting piece includes a mounting through hole opened at the bottom of the unmanned vehicle. A sealing plate is fixedly connected to the inner wall of the mounting through hole, and a hydraulic tank is fixedly connected to the bottom of the sealing plate; A clamping component, which is fixedly connected to the top of the unmanned vehicle through a transmission piece; The transmission piece includes a liquid storage tank fixedly connected to the top of the unmanned vehicle, and a transmission pipe is opened on the side wall of the liquid storage tank; Among them, when the bearing plate rotates downward due to sudden braking, the downward pressure of the bearing plate will force the hydraulic oil in the hydraulic tank to be transmitted to the inner wall of the liquid storage tank through the transmission pipe, enabling the clamping component to perform the clamping process.

[0007] Preferably, the mounting component includes a mounting groove opened at the top of the unmanned vehicle. A receiving box is fixedly connected to the inner wall of the mounting groove, and a sliding groove is opened on the inner wall of the mounting groove; Among them, the fixed column is located at the front of the vehicle head. One end of the bearing plate far from the fixed column will swing up and down under the drive of the internal component.

[0008] Preferably, the load-bearing component includes friction lines opened at the top of the bearing plate, and an inclined surface is opened at the bottom of the friction lines; Among them, when the driving component drives the control component to slide, the control component will slide along the inclined surface of the inclined surface.

[0009] Preferably, the driving component includes a numerically controlled telescopic rod fixedly connected to the inner wall of the accommodation box. The other end of the numerically controlled telescopic rod is fixedly connected with a pushing plate, and a pulling rod is fixedly connected to the side wall of the pushing plate; Wherein, when the unmanned vehicle brakes suddenly, the numerically controlled telescopic rod contracts rapidly, causing the control component to slide along the inclined surface of the inclined plane. At this time, the bearing plate will rotate downward.

[0010] Preferably, the control component includes a sliding block fixedly connected to the end of the pulling rod away from the pushing plate. A ball is rotatably connected to the top of the sliding block, and the bottom of the sliding block is slidably connected to the inner wall of the sliding groove. The end of the transmission pipe away from the liquid storage tank is connected to the bottom of the side wall of the hydraulic tank in a penetrating manner; Wherein, when the pulling rod is pulled and slides by the numerically controlled telescopic rod, the ball will slide along the bottom of the inclined plane. As the distance between the inclined plane and the outer wall of the installation groove expands, the bearing plate will rotate downward at this time.

[0011] Preferably, the hydraulic component includes a piston plate slidably connected to the inner wall of the hydraulic tank. A sliding rod is fixedly connected to the top of the piston plate. A rotating block is rotatably connected to the inner wall of the sliding rod, and the top of the rotating block is fixedly connected to the bottom of the bearing plate; Wherein, when the bearing plate rotates downward, the pressure generated by the bearing plate will force the sliding rod to drive the piston plate to slide downward, pressing the hydraulic oil inside the hydraulic tank to be transmitted through the transmission pipe to the inner wall of the liquid storage tank; Taking advantage of the above characteristics of the bearing plate rotating downward, a hydraulic mechanism is arranged inside the device. When the bearing plate rotates downward, the bearing plate will drive the piston plate to slide downward along the inner wall of the hydraulic tank through the rotating block and the sliding rod. The applied pressure will force the hydraulic oil inside the hydraulic tank to be transmitted through the transmission pipe to the liquid storage tank, causing the hydraulic oil inside the liquid storage tank to expand outward. The above expansion force will force the hydraulic telescopic rod of the clamping component to extend outward, and the extended hydraulic telescopic rod drives the gas storage box to contact the outer wall of the container, thereby effectively offsetting part of the lateral potential energy.

[0012] Preferably, the hydraulic component includes a hydraulic telescopic rod penetratingly connected to the inner wall of the liquid storage tank. The end of the hydraulic telescopic rod away from the liquid storage tank is fixedly connected with a gas storage box. A sliding bracket is slidably connected to the side wall of the gas storage box, and a sliding plate is slidably connected to the inner wall of the sliding bracket; Wherein, after the hydraulic oil is transmitted from the liquid storage tank to the inner wall of the hydraulic telescopic rod, the hydraulic telescopic rod will extend and drive the sliding plate to contact the zigzag outer wall of the container; Taking advantage of the above characteristics of the gas storage box moving outward, a sliding plate is arranged inside the device. The gas storage box moves outward, driving several sliding plates to contact the outer wall of the container. After the sliding plate contacts the outer wall of the container, it will slide to varying degrees due to the zigzag outer wall of the container, as Figure 8 shown, so that when the clamping component clamps the container, the contact area can be increased and the resistance to potential energy can be improved.

[0013] The present invention has the following beneficial effects: (1) During the transportation of the driverless vehicle, when an emergency brake occurs, the numerical control telescopic rod quickly contracts. When the pulling rod slides under the pulling of the numerical control telescopic rod, the ball will slide along the bottom of the inclined surface. As the distance between the inclined surface and the outer wall of the installation groove expands, at this time, the bearing plate will rotate downward around the fixed column. With the change of the rotation angle of the bearing plate, the container at the top of the bearing plate will tilt synchronously, as Figure 6 shown. This change causes the pressure of the potential energy on the trolley to change from state G to state F. The pressure of F is downward inclination. At this time, it can be regarded that the pressure generated by the F potential energy is formed by two forces, one is to the left and the other is downward. Moreover, when the container and the internal items are subjected to the downward potential energy pressure, the contact pressure between the internal goods and the bottom goods will increase, improving the contact tightness between the upper and lower goods. The tightly fitted goods can effectively offset the lateral potential energy pressure, effectively reducing the phenomenon of the goods falling due to emergency braking.

[0014] (2) Utilizing the above-mentioned characteristic that the bearing plate rotates downward, a hydraulic mechanism is arranged inside the device. When the bearing plate rotates downward, the bearing plate will drive the piston plate to slide downward along the inner wall of the hydraulic tank through the rotating block and the sliding rod. The applied pressure will force the hydraulic oil inside the hydraulic tank to be transmitted to the liquid storage tank through the transmission pipe, causing the hydraulic oil inside the liquid storage tank to expand outward. The above expansion force will force the hydraulic telescopic rod of the clamping assembly to extend outward, and the extended hydraulic telescopic rod drives the gas storage box to contact the outer wall of the container, thereby effectively offsetting part of the lateral potential energy.

[0015] (3) Utilizing the above-mentioned characteristic that the gas storage box moves outward, a sliding plate is arranged inside the device. When the gas storage box moves outward, it drives several sliding plates to contact the outer wall of the container. After the sliding plate contacts the outer wall of the container, it will slide to varying degrees due to the zigzag outer wall of the container, as Figure 8 shown. When the clamping assembly clamps the container, it can increase the contact area and improve the resistance to potential energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] In Embodiment 1, please refer to Figure 1 - Figure 4 , the present invention is a cargo loading and transportation device for port transportation and loading and unloading, including an unmanned vehicle 13; A transportation mechanism 1, the transportation mechanism 1 is arranged on the inner wall of the unmanned vehicle 13, and when in use, a container is placed on the top of the unmanned vehicle 13; A driving mechanism 2, the driving mechanism 2 is rotatably arranged on the inner wall of the transportation mechanism 1, and is used to adjust the inclination angle of the container on the top when the unmanned vehicle 13 makes an emergency brake; The hydraulic mechanism 3 is fixedly arranged on the side wall of the transportation mechanism 1 and is used for clamping and limiting the outer wall of the container. Before use, the container is first placed on the top of the unmanned vehicle 13. During the transportation of the unmanned vehicle 13, when an emergency brake occurs, the driving mechanism 2 will adjust the inclination angle of the container, and then the hydraulic mechanism 3 will clamp the end of the container to limit the movement of the container.

[0021] The transportation mechanism 1 includes: The installation component 11 is arranged on the inner wall of the unmanned vehicle 13 and is used to provide an installation space for the driving mechanism 2 and the hydraulic mechanism 3. The load-bearing component 12 is fixedly connected to the inner wall of the installation component 11 through a connecting piece. The connecting piece includes a fixed column 121 fixedly connected to the inner wall of the unmanned vehicle 13. A bearing plate 122 is rotatably connected to the outer wall of the fixed column 121. The container is placed on the top of the bearing plate 122, and the pressure received by the bearing plate 122 will be transmitted to the unmanned vehicle 13. With the change of the rotation angle of the bearing plate 122, the container on the top of the bearing plate 122 will tilt synchronously. As Figure 6 shown, this change causes the pressure of the potential energy on the trolley to change from the G state to the F state. The pressure of F is a downward inclination. At this time, it can be regarded that the pressure generated by the F potential energy is formed by two forces, one to the left and the other downward. Moreover, when the container and the internal items are subjected to the downward potential energy pressure, the contact pressure between the internal goods and the bottom goods will increase, improving the contact tightness between the upper and lower goods. The tightly fitted goods can effectively offset the lateral potential energy pressure and effectively reduce the phenomenon of the goods falling due to emergency braking. The driving mechanism 2 includes: The driving component 21 is fixedly arranged on the inner wall of the installation component 11 and is used to provide power for the adjustment of the equipment. The control component 22 is slidably arranged on the inner wall of the installation component 11 and is used to change the driving force generated by the driving component 21 into the inclination angle of the bearing plate 122. Before the unmanned vehicle 13 makes an emergency brake, the driving component 21 quickly generates a driving force, forcing the control component 22 to slide on the inner wall of the installation component 11, forcing the bearing plate 122 to move downward. Without changing the direction of the potential energy, the angle of the container is changed, and the potential energy forces the goods in the container to tilt synchronously and increases the pressure between the goods.

[0022] The hydraulic mechanism 3 includes: The hydraulic component 31 is fixedly arranged on the inner wall of the unmanned vehicle 13 through a mounting piece. The mounting member includes a mounting through-hole 311 formed at the bottom of the driverless vehicle 13. A sealing plate 312 is fixedly connected to the inner wall of the mounting through-hole 311, and a hydraulic tank 313 is fixedly connected to the bottom of the sealing plate 312; A clamping assembly 32, and the clamping assembly 32 is fixedly connected to the top of the driverless vehicle 13 through a transmission member; The transmission member includes a liquid storage tank 321 fixedly connected to the top of the driverless vehicle 13, and a transmission pipe 322 is formed in the side wall of the liquid storage tank 321; Wherein, when the bearing plate 122 rotates downward due to sudden braking, the downward pressure of the bearing plate 122 will force the hydraulic oil inside the hydraulic tank 313 to be transmitted through the transmission pipe 322 to the inner wall of the liquid storage tank 321, so that the clamping assembly 32 performs the clamping process.

[0023] Embodiment 2, please refer to Figure 4 - Figure 8 , the present invention is a cargo loading and transportation device for port transportation and loading and unloading. On the basis of Example 1, the installation assembly 11 includes an installation groove 111 formed at the top of the driverless vehicle 13. A receiving box 112 is fixedly connected to the inner wall of the installation groove 111, and a sliding groove 113 is formed in the inner wall of the installation groove 111; Wherein, the fixed column 121 is located at the front of the vehicle head, and one end of the bearing plate 122 away from the fixed column 121 will swing up and down under the drive of the internal component.

[0024] The load-bearing assembly 12 includes friction lines 123 formed at the top of the bearing plate 122, and an inclined surface 124 is formed at the bottom of the friction lines 123; Wherein, when the driving component 21 drives the control component 22 to slide, the control component 22 will slide along the inclined surface of the inclined surface 124.

[0025] The driving component 21 includes a numerically controlled telescopic rod 211 fixedly connected to the inner wall of the receiving box 112. The other end of the numerically controlled telescopic rod 211 is fixedly connected to a pushing plate 212, and a pulling rod 213 is fixedly connected to the side wall of the pushing plate 212; Wherein, when the driverless vehicle 13 suddenly brakes, the numerically controlled telescopic rod 211 contracts rapidly, so that the control component 22 slides along the inclined surface of the inclined surface 124. At this time, the bearing plate 122 will rotate downward.

[0026] The control component 22 includes a sliding block 221 fixedly connected to one end of the pulling rod 213 away from the pushing plate 212. A ball 222 is rotatably connected to the top of the sliding block 221. The bottom of the sliding block 221 is slidably connected to the inner wall of the sliding groove 113. The end of the transmission pipe 322 away from the liquid storage tank 321 is connected to the bottom of the side wall of the hydraulic tank 313 in a penetrating manner; Among them, when the pulling rod 213 is pulled and slides by the numerically controlled telescopic rod 211, the ball 222 will slide along the bottom of the inclined surface 124. As the distance between the inclined surface 124 and the outer wall of the installation groove 111 expands, the bearing plate 122 will rotate downward at this time.

[0027] The hydraulic component 31 includes a piston plate 314 slidably connected to the inner wall of the hydraulic tank 313. A sliding rod 315 is fixedly connected to the top of the piston plate 314. A rotating block 316 is rotatably connected to the inner wall of the sliding rod 315. The top of the rotating block 316 is fixedly connected to the bottom of the bearing plate 122; Among them, when the bearing plate 122 rotates downward, the pressure generated by the bearing plate 122 will force the sliding rod 315 to drive the piston plate 314 to slide downward, pressing the hydraulic oil inside the hydraulic tank 313 to be transmitted to the inner wall of the liquid storage tank 321 through the transmission pipe 322; Utilizing the characteristic that the bearing plate 122 rotates downward, a hydraulic mechanism 3 is provided inside the device. When the bearing plate 122 rotates downward, the bearing plate 122 will drive the piston plate 314 to slide downward along the inner wall of the hydraulic tank 313 through the rotating block 316 and the sliding rod 315. The applied pressure will force the hydraulic oil inside the hydraulic tank 313 to be transmitted to the liquid storage tank 321 through the transmission pipe 322, causing the hydraulic oil inside the liquid storage tank 321 to expand outward. The above expansion force will force the hydraulic telescopic rod 323 of the clamping assembly to extend outward. The extended hydraulic telescopic rod 323 drives the gas storage box 324 to contact the outer wall of the container, thereby effectively offsetting part of the lateral potential energy.

[0028] The hydraulic component 31 includes a hydraulic telescopic rod 323 connected through the inner wall of the liquid storage tank 321. One end of the hydraulic telescopic rod 323 away from the liquid storage tank 321 is fixedly connected with a gas storage box 324. A sliding bracket 325 is slidably connected to the side wall of the gas storage box 324. A sliding plate 326 is slidably connected to the inner wall of the sliding bracket 325; Among them, after the hydraulic oil is transmitted to the inner wall of the hydraulic telescopic rod 323 through the liquid storage tank 321, the hydraulic telescopic rod 323 will extend and drive the sliding plate 326 to contact the zigzag outer wall of the container; Utilizing the characteristic that the gas storage box 324 moves outward, a sliding plate 326 is provided inside the device. The gas storage box 324 moves outward, driving several sliding plates 326 to contact the outer wall of the container. After the sliding plate 326 contacts the outer wall of the container, it will slide to varying degrees due to the zigzag outer wall of the container, such as Figure 8 shown, so that when the clamping assembly 32 clamps the container, the contact area can be increased and the resistance to potential energy can be improved.

[0029] A specific application of this embodiment is: Before use, first place the container on the top of the bearing plate 122. After ensuring that the container is stable, the unmanned vehicle 13 starts the transportation process; During the transportation of the driverless vehicle 13, when an emergency brake occurs, the numerically controlled telescopic rod 211 contracts rapidly. When the pulling rod 213 slides under the pulling of the numerically controlled telescopic rod 211, the ball 222 will slide along the bottom of the inclined surface 124. As the distance between the inclined surface 124 and the outer wall of the installation groove 111 expands, at this time, the bearing plate 122 will rotate downward around the fixed column. With the change in the rotation angle of the bearing plate 122, the container at the top of the bearing plate 122 will tilt synchronously, as Figure 6 shown. This change causes the pressure of the potential energy on the trolley to change from the G state to the F state. The pressure of F is downward tilt. At this time, it can be regarded that the pressure generated by the F potential energy is formed by two forces, one is to the left and the other is downward. Moreover, when the container and the internal items are subjected to the downward potential energy pressure, the contact pressure between the internal goods and the bottom goods will increase, improving the contact tightness between the upper and lower goods. The tightly fitting goods can effectively offset the lateral potential energy pressure, effectively reducing the phenomenon of the goods falling due to the emergency brake; Utilizing the above characteristics of the downward rotation of the bearing plate 122, a hydraulic mechanism 3 is provided inside the device. When the bearing plate 122 rotates downward, the bearing plate 122 will drive the piston plate 314 to slide downward along the inner wall of the hydraulic tank 313 through the rotating block 316 and the sliding rod 315. The applied pressure will force the hydraulic oil inside the hydraulic tank 313 to be transmitted to the liquid storage tank 321 through the transmission pipe 322, causing the hydraulic oil inside the liquid storage tank 321 to expand outward. The above expansion force will force the hydraulic telescopic rod 323 of the clamping assembly to extend outward. The extended hydraulic telescopic rod 323 drives the air storage box 324 to contact the outer wall of the container, thereby effectively offsetting part of the lateral potential energy; Utilizing the above characteristics of the outward movement of the air storage box 324, a sliding plate 326 is provided inside the device. When the air storage box 324 moves outward, it drives several sliding plates 326 to contact the outer wall of the container. After the sliding plate 326 contacts the outer wall of the container, it will slide to varying degrees due to the uneven outer wall of the container, as Figure 8 shown. When the clamping assembly 32 clamps the container, it can increase the contact area and improve the resistance to potential energy; After the driverless vehicle 13 stops completely, at this time, the numerically controlled telescopic rod 211 will drive the sliding block 221 to reset, making the bearing plate 122 return to a stable state again.

The other end of the numerically controlled telescopic rod (211) is fixedly connected with a pushing plate (212), and a pulling rod (213) is fixedly connected to the side wall of the pushing plate (212). Among them, when the unmanned vehicle (13) brakes suddenly, the numerically controlled telescopic rod (211) contracts rapidly, so that the control component (22) slides along the inclined surface of the inclined surface (124). At this time, the bearing plate (122) will rotate downward.

6. A cargo loading and transportation device for port transportation and handling according to claim 5, characterized in that: The control component (22) includes a sliding block (221) fixedly connected to one end of the pulling rod (213) away from the pushing plate (212). A ball (222) is rotatably connected to the top of the sliding block (221). The bottom of the sliding block (221) is slidably connected to the inner wall of the sliding groove (113). One end of the transmission pipe (322) away from the liquid storage tank (321) is connected to the bottom of the side wall of the hydraulic tank (313) in a penetrating manner. Among them, when the pulling rod (213) is pulled and slides by the numerically controlled telescopic rod (211), the ball (222) will slide along the bottom of the inclined surface (124). As the distance between the inclined surface of the inclined surface (124) and the outer wall of the installation groove (111) expands, at this time, the bearing plate (122) will rotate downward.

7. A cargo loading and transporting device for port transportation and handling according to claim 6, characterized in that: The hydraulic component (31) includes a piston plate (314) slidably connected to the inner wall of the hydraulic tank (313). A sliding rod (315) is fixedly connected to the top of the piston plate (314). A rotating block (316) is rotatably connected to the inner wall of the sliding rod (315), and the top of the rotating block (316) is fixedly connected to the bottom of the bearing plate (122). Among them, when the bearing plate (122) rotates downward, the pressure generated by the bearing plate (122) will force the sliding rod (315) to drive the piston plate (314) to slide downward, pressing the hydraulic oil inside the hydraulic tank (313) to be transmitted to the inner wall of the liquid storage tank (321) through the transmission pipe (322).

8. A cargo loading and transportation device for port transportation and loading and unloading according to claim 7, characterized in that: The hydraulic component (31) includes a hydraulic telescopic rod (323) connected through and at the inner wall of the liquid storage tank (321). One end of the hydraulic telescopic rod (323) far from the liquid storage tank (321) is fixedly connected to a gas storage box (324). A sliding bracket (325) is slidably connected to the side wall of the gas storage box (324), and a sliding plate (326) is slidably connected to the inner wall of the sliding bracket (325). Among them, after the hydraulic oil is transmitted to the inner wall of the hydraulic telescopic rod (323) through the liquid storage tank (321), the hydraulic telescopic rod (323) will extend and drive the sliding plate (326) to contact the zigzag outer wall of the container.
