Description

Technical Field

[0001] This invention relates to the field of container transport vehicle technology, and in particular to a container loading and unloading device and a container transport vehicle. Background Technology

[0002] Container shipping is an advanced and modern mode of transportation that uses containers as the transport unit. In inland areas, it mainly uses semi-trailer trucks for road transport. For container loading and unloading, large ports generally rely on specialized lifting equipment such as reach stackers and gantry cranes, while smaller freight stations or user locations often require renting truck cranes or similar equipment. This rudimentary operating method depends on these specialized lifting equipment to complete container loading and unloading. Therefore, current container trucks cannot perform self-lifting, resulting in excessive reliance on these specialized equipment. This not only increases operating costs but also reduces the efficiency of container loading and unloading operations. Summary of the Invention

[0003] To address the problems in the prior art, this application proposes a container loading and unloading device and a container transport vehicle, which can solve the problem that existing container transport vehicles cannot load and unload containers independently.

[0004] One aspect of the present invention provides a container loading and unloading device, the container loading and unloading device including a sub-frame, a tilting frame horizontally hinged to the sub-frame, and a tilting drive component mounted on the sub-frame, the tilting drive component capable of driving the tilting frame to rotate relative to the sub-frame, the tilting frame being provided with a length telescopic drive component capable of extending and retracting along the length direction of the tilting frame, the telescopic end of the length telescopic drive component being mounted with a mounting frame, the mounting frame being mounted with an adjustable telescopic drive component, the telescopic end of the adjustable telescopic drive component being mounted with a support frame, and the support frame being mounted with a container gripper.

[0005] As a further improvement to the above technical solution:

[0006] The aforementioned container loading and unloading device further includes a container gripper comprising a support beam assembly and two gripper plates. Both ends of the support beam assembly are equipped with clamping telescopic drive components capable of extending and retracting along the length of the support beam assembly. The two gripper plates are correspondingly installed on the telescopic ends of the two clamping telescopic drive components. Each gripper plate is provided with a limiting pin. The two clamping telescopic drive components can drive the two gripper plates to move closer to each other so that the limiting pin is positioned within the limiting hole of the container.

[0007] In the aforementioned container loading and unloading device, the support frame is further horizontally hinged with a hinge block, the support beam assembly is mounted on the hinge block, and the support frame is also horizontally hinged with two rotating telescopic drive members. The two rotating telescopic drive members are symmetrically distributed on both sides of the hinge block, and the telescopic ends of the two rotating telescopic drive members are horizontally hinged to the support beam assembly. The rotating telescopic drive members can drive the support beam assembly to rotate relative to the support frame.

[0008] In the aforementioned container loading and unloading device, a hook is horizontally hinged to the side of the hinge block away from the support beam assembly, and a rotary telescopic drive is also horizontally hinged to the support beam assembly. The telescopic end of the rotary telescopic drive is horizontally hinged to the hook, and the rotary telescopic drive can drive the hook to rotate relative to the hinge block.

[0009] In the aforementioned container loading and unloading device, the support beam assembly further includes a sleeve seat and a support beam. The support beam is sleeved inside the sleeve seat. A connecting pin is provided on the hinge block. The connecting pin passes through the sleeve seat and the support beam in sequence. The sleeve seat is fixed relative to the connecting pin, and the support beam is rotatable relative to the connecting pin.

[0010] Furthermore, in the aforementioned container loading and unloading device, the sleeve seat is provided with elastic elements on the upper and lower sides of the inner sidewalls on both sides of the connecting pin, and the elastic elements can buffer the rotation of the support beam relative to the sleeve seat.

[0011] Furthermore, in the aforementioned container loading and unloading device, a guide positioning seat is rotatably mounted on the gripper plate via the limiting pin, and the guide positioning seat can rotate relative to the gripper plate under its own weight.

[0012] Furthermore, the aforementioned container loading and unloading device also includes a container guiding device at the rear of the subframe.

[0013] Furthermore, in the aforementioned container loading and unloading device, a placement seat is installed on the subframe for placing containers.

[0014] Another aspect of the present invention provides a container transport vehicle, the container transport vehicle including a chassis and a container loading and unloading device as described above, the subframe being fixedly mounted on the chassis.

[0015] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0016] The container loading and unloading device and container transport vehicle provided by this invention have at least the following advantages compared with the prior art: When loading a container, firstly, the tilting drive drives the tilting frame to rotate relative to the subframe towards the rear of the subframe. Then, the length extension drive extends, and the extension of the extension drive is adjusted so that the container gripper on the support frame can grab the container. After the container gripper grabs the container, the length extension drive retracts, the extension drive is adjusted, and the tilting drive drives the tilting frame to rotate relative to the subframe towards the front of the subframe, finally placing the container on the subframe. When unloading the container, the operation is reversed. This container loading and unloading device can automatically load and unload containers without relying on specialized lifting equipment, thereby reducing operating costs and improving the efficiency of container loading and unloading operations.

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] This invention provides a container loading and unloading device 100, which can solve the problem that existing container transport vehicles cannot load and unload containers themselves.

[0035] Please see Figure 1 The container loading and unloading device 100 provided in this embodiment of the invention includes a sub-frame 110, a tilting frame 120 horizontally hinged to the sub-frame 110, and a tilting drive 111 mounted on the sub-frame 110. The tilting drive 111 can drive the tilting frame 120 to rotate relative to the sub-frame 110. The tilting frame 120 is provided with a length telescopic drive 121 that can extend and retract along the length direction of the tilting frame 120. A mounting frame 130 is mounted on the telescopic end of the length telescopic drive 121. An adjustable telescopic drive 131 is mounted on the mounting frame 130. A support frame 132 is mounted on the telescopic end of the adjustable telescopic drive 131. A container gripper 140 is mounted on the support frame 132.

[0036] When a container needs to be loaded, the tilting drive 111 first drives the tilting frame 120 to rotate relative to the sub-frame 110 towards the rear of the sub-frame 110. Then, the length extension drive 121 extends, and the extension drive 131 is adjusted to extend so that the container gripper 140 on the support frame 132 can grab the container. After the container gripper 140 grabs the container, the length extension drive 121 retracts, the extension drive 131 retracts, and the tilting drive 111 drives the tilting frame 120 to rotate relative to the sub-frame 110 towards the head of the sub-frame 110, finally placing the container on the sub-frame 110. When unloading the container, the operation is reversed. The container loading and unloading device 100 provided in this embodiment of the invention can achieve self-loading and unloading of containers without relying on these specialized lifting equipment, thereby reducing operating costs and improving the efficiency of container loading and unloading operations.

[0037] The container loading and unloading device 100 provided in this embodiment of the invention, for details please refer to... Figure 2 , Figure 3 as well as Figure 5 The container gripper 140 includes a support beam assembly and two gripping plates 141. Both ends of the support beam assembly are equipped with clamping telescopic drive members 142 that can extend and retract along the length of the support beam assembly. The two gripping plates 141 are correspondingly installed at the telescopic ends of the two clamping telescopic drive members 142. Each gripping plate 141 is provided with a limiting pin 143. The two clamping telescopic drive members 142 can drive the two gripping plates 141 closer together so that the limiting pin 143 is positioned within the limiting hole of the container. When the container gripper 140 needs to grip a container, firstly, the two clamping telescopic drive members 142 extend relative to each other, causing the two gripping plates 141 to move away from each other. Then, the container gripper 140 is driven closer to the container so that the two gripping plates 141 are positioned on opposite sides of the container. Finally, the two clamping telescopic drive members 142 retract relative to each other, causing the two gripping plates 141 to move closer together so that the limiting pin 143 is positioned within the limiting hole of the container, thereby completing the gripping of the container.

[0038] The container loading and unloading device 100 provided in this embodiment of the invention, further, please refer to... Figure 2 and Figure 3A guide positioning seat 152 is rotatably mounted on the gripper plate 141 via a limiting pin 143. The guide positioning seat 152 can rotate relative to the gripper plate 141 under its own weight. As the gripper plate 141 moves, the guide positioning seat 152 can rotate relative to the gripper plate 141 under its own weight, so that the guide positioning seat 152 always remains in a fixed state, which facilitates the guidance and positioning of the container. In this embodiment, the guide positioning seat 152 includes a vertical plate and a horizontal plate mounted on the upper side of the vertical plate. The vertical plate can abut against the front face of the container, and the horizontal plate can abut against the upper face of the container.

The two rotating telescopic drive members 145 are symmetrically distributed on both sides of the hinge block 144. The telescopic ends of both rotating telescopic drive members 145 are horizontally hinged to the support beam assembly. The rotating telescopic drive members 145 can drive the support beam assembly to rotate relative to the support frame 132. By extending and retracting the rotating telescopic drive members 145, the support beam assembly can be driven to rotate relative to the mounting frame 130, thereby adjusting the rotation angle of the support beam assembly relative to the mounting frame 130 so that the limiting pin 143 can be aligned with the limiting hole of the container.

[0040] The container loading and unloading device 100 provided in this embodiment of the invention, further, please refer to... Figure 4 A hook 146 is horizontally hinged to the side of the hinge block 144 away from the support beam assembly.

The telescopic end of the rotary telescopic drive 147 is horizontally hinged to the hook 146, and the rotary telescopic drive 147 can drive the hook 146 to rotate relative to the hinge block 144. When the container loading and unloading device 100 is used to load and unload transport pallets, the support beam assembly can be driven to rotate relative to the mounting frame 130 by rotating the telescopic drive 145 to extend and retract. At the same time, the rotary telescopic drive 147 drives the hook 146 to rotate relative to the hinge block 144, so that the hook 146 can hook onto the connecting part of the transport pallet, thereby achieving the purpose of lifting the transport pallet.

[0041] In this embodiment, please refer to Figure 2 , Figure 3 as well as Figure 5The support beam assembly includes a sleeve seat 148 and a support beam 149.
