Description

Technical Field

[0001] This utility model relates to the technical field of trailer protection devices, and in particular to a protective device for a container trailer. Background Technology

[0002] A container is a special container or carrier used in air transport (cargo, mail, baggage). It includes pallets and containers and can be transported by trailer.

[0003] Patent CN213735282U discloses a container flatbed trailer assembly, including a vehicle body, an axle assembly and a buffer at the bottom of the vehicle body, a slewing bridge assembly and a tow handle assembly connected to the slewing bridge assembly at the end of the vehicle body, and two and three sets of axle assemblies at the front and rear ends of the bottom of the vehicle body, respectively. Each axle assembly includes an axle and tires at both ends of the axle. The buffer includes a buffer bracket connected to the axle and a mounting bracket connected to a connecting frame at the bottom of the vehicle body. However, when the trailer travels on bumpy roads or sloping sections, the container is prone to slipping off the trailer, posing a safety hazard during transport. Utility Model Content

[0004] In view of the above problems, this utility model provides a protective device for container trailers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for a container trailer is provided, comprising two first baffles and two second baffles. The two first baffles are respectively disposed on both sides of the trailer, and the two second baffles are movably disposed on the other two sides of the trailer. The two first baffles and the two second baffles can together form an installation space on the trailer for accommodating the container. The trailer has an installation opening for accommodating the second baffles, and a connecting rod is horizontally disposed in the installation opening. The second baffles have a strip-shaped hole for the connecting rod to pass through, so that the second baffles can move up and down and can rotate about the connecting rod as an axis. The second baffles have a limiting block for moving down and abutting against the top of the trailer to limit their own rotation. When the second baffles move up, they can rotate about the connecting rod as an axis and the limiting block overlaps the top of the trailer.

[0007] Furthermore, it also includes a limiting member for restricting the upward movement of the second baffle. The limiting member includes a fixed block and a movable block. The fixed block is fixed on the top of the trailer and located on one side of the second baffle. The movable block is rotatably disposed on the fixed block. One end of the movable block movably abuts against the top of the trailer, and the other end of the movable block forms a limiting opening between it and the top of the trailer for the limiting block to pass through.

[0008] Furthermore, the movable block is connected to the fixed block by bolts and nuts. Both the fixed block and the movable block have through holes. The bolts pass through the two through holes and are threadedly connected to the nuts. The movable block is rotatably connected to the fixed block by the bolts.

[0009] Furthermore, the movable block is equipped with a first handle; the second baffle is equipped with a second handle.

[0010] Furthermore, the trailer is equipped with an array of multiple unpowered rollers, and a second baffle is located on one side of the trailer parallel to the axis of the unpowered rollers.

[0011] Furthermore, at least two of the first baffle and the second baffle are provided at intervals on the corresponding trailer sidewalls.

[0012] The beneficial effects of this utility model are as follows: After the worker moves the second baffle upward, it can be rotated until the limiting block overlaps with the top of the trailer. At this time, the second baffle is lower than the top of the trailer, which opens the installation space for loading and unloading the container. After the container is installed, the second baffle can be rotated and made vertical, and then the second baffle can be moved downward until the limiting block overlaps with the top of the trailer, which restricts the rotation of the second baffle and works with the first baffle to enclose the container. During transportation, the container is prevented from sliding out of the trailer by the first and second baffles enclosing it, which improves the safety of container transportation.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a protective device for a container trailer, referring to... Figure 1 , Figure 2 and Figure 3 The system includes two first baffles 2 and two second baffles 3. The two first baffles 2 are bolted 6 to both sides of the trailer 1, and the two second baffles 3 are movably disposed on the other two sides of the trailer 1. The two first baffles 2 and the two second baffles 3 can together form an installation space on the trailer 1 to accommodate the container. The trailer 1 has an installation opening 11 for accommodating the second baffles 3. A connecting rod 12 is horizontally welded into the installation opening 11. The second baffles 3 have a strip-shaped hole 31 for the connecting rod 12 to pass through, so that the second baffles 3 can move up and down and rotate about the connecting rod 12. A limiting block 4 is welded to the second baffles 3 to abut against the top of the trailer 1 after moving down to limit its own rotation. After moving up, the second baffles 3 can rotate about the connecting rod 12 and the limiting block 4 overlaps the top of the trailer 1.

[0021] In this embodiment, after the worker moves the second baffle 3 upwards, it can be rotated until the limiting block 4 overlaps the top of the trailer 1. At this point, the second baffle 3 is lower than the top of the trailer 1, opening up the installation space for loading and unloading the container. After the container is installed, the second baffle 3 can be rotated and made vertical, then moved downwards until the limiting block 4 overlaps the top of the trailer 1, thus restricting the rotation of the second baffle 3. At this point, the second baffle 3 is higher than the top of the trailer 1, working in conjunction with the first baffle 2 to enclose the container. During transportation, the first baffle 2 and the second baffle 3 together enclose the container, preventing it from sliding out of the trailer 1, thus improving the safety of container transportation.

[0022] Reference Figure 4 and Figure 5 It also includes a limiting member 5 for restricting the upward movement of the second baffle 3. The limiting member 5 includes a fixed block 51 and a movable block 52. The fixed block 51 is welded to the top of the trailer 1 and located on one side of the second baffle 3. The movable block 52 is rotatably disposed on the fixed block 51. One end of the movable block 52 is in movable contact with the top of the trailer 1, and a limiting opening 521 is formed between the other end of the movable block 52 and the top of the trailer 1 for the limiting block 4 to pass through.

[0023] In this embodiment, the second baffle 3 needs to be tilted downwards so that the limiting block 4 slides into contact with the outer wall of one end of the movable block 52, causing the movable block 52 to rotate. After the limiting block 4 enters the limiting opening 521, the second baffle 3 rotates to make itself vertical, and then moves vertically downwards until the limiting block 4 overlaps the top of the trailer. At this time, the limiting block 4 is located at one end of the bottom of the movable block 52 and there is a gap between it and the bottom wall of the movable block 52. When passing through bumpy road sections, the second baffle 3 will move upwards due to vibration and abut against the bottom wall of the movable block 52. Since the other end of the bottom of the movable block 52 is blocked by the trailer 1, the second baffle 3 will be blocked by the movable block 52 within the limiting opening 521 during the process of moving vertically upwards due to vibration. This has the effect of improving the protective stability of the second baffle 3.

[0024] During unloading, the workers need to move the second baffle 3 upward and separate the limiting block 4 from the trailer 1. Then, they need to rotate the second baffle 3 and tilt it upward to move the limiting block 4 out of the limiting port 521, so that the second baffle 3 can be moved and the installation space can be opened.

[0025] To facilitate the assembly and disassembly of the movable block 52, the movable block 52 is connected to the fixed block 51 by bolts 6 and nuts 7. Both the fixed block 51 and the movable block 52 have through holes. The bolts 6 pass through the two through holes and are threadedly connected to the nuts 7. The movable block 52 is rotatably connected to the fixed block 51 by bolts 6.

[0026] To facilitate the movement of the movable block 52 and the second baffle 3 by the staff, a first handle 522 is welded on the movable block 52 and a second handle 8 is welded on the second baffle 3.

[0027] Furthermore, the trailer 1 is provided with an array of multiple unpowered rollers 13, and the second baffle 3 is provided on one side of the trailer 1 parallel to the axis of the unpowered rollers 13.

[0028] In this embodiment, since the second baffle 3 is parallel to the axis of the unpowered rollers 13, after moving the second baffle 3 and opening the installation space, the operator can first move one end of the container to one end of the array of unpowered rollers 13, and then push the container into the installation space. Because the unpowered rollers 13 roll in contact with the bottom of the container, the frictional force on the bottom of the container is reduced, thereby reducing the labor intensity of the operator.

[0029] Furthermore, at least two of the first baffle 2 and the second baffle 3 are provided at intervals on the corresponding side wall of the trailer 1.

[0030] In this embodiment, two first baffles 2 / second baffles 3 are provided at intervals on each side of the trailer 1, which can save materials and ensure the protective function of the first baffles 2 and the second baffles 3.

[0031] The implementation principle of a protective device for a container trailer according to an embodiment of this application is as follows: After the operator moves the second baffle 3 upwards, it can be rotated until the limiting block 4 overlaps the top of the trailer 1. At this time, the second baffle 3 is lower than the top of the trailer 1, thus opening the installation space for loading and unloading the container. After the container is installed, the second baffle 3 can be rotated and made vertical, and then the second baffle 3 can be moved downwards until the limiting block 4 overlaps the top of the trailer 1, thereby restricting the rotation of the second baffle 3 to cooperate with the first baffle 2 to enclose the container. During transportation, the first baffle 2 and the second baffle 3 together enclose the container, preventing the container from sliding out of the trailer 1, thus improving the safety of container transportation.
