Description

Technical Field

[0001] This utility model relates to the field of self-unloading cargo box technology, specifically a side-tipping self-unloading cargo box. Background Technology

[0002] In the fields of logistics and transportation and engineering construction, the efficiency and safety of cargo transportation have always been key considerations. As an important piece of equipment that can achieve automatic unloading, self-unloading cargo containers have been widely used in the market due to their advantages in improving unloading efficiency and reducing manual labor intensity and costs. Among them, the side-tipping self-unloading cargo container is a common type. Through a specific lifting and tipping mechanism, the side of the cargo container is lifted upward, so that the cargo is unloaded from the side of the container under the action of gravity, which brings great convenience to cargo loading and unloading. However, most side-tipping self-unloading freight containers currently rely on a single source of lifting power. If the main power system fails, unloading operations will not be able to proceed normally, severely affecting transportation efficiency. The operation methods are often not convenient enough, and some require operators to manually operate the relevant mechanisms near the vehicle to unload the goods. This not only increases the workload of the operators, but also poses a potential threat to the personal safety of the operators in some complex or dangerous unloading environments.

A first movable block is provided inside the horizontal groove, and one side of the first movable block is connected to the inner wall of the horizontal groove through a first spring. The base has assembly slots on both sides, and a guide rod is provided inside the assembly slot. A second spring is sleeved on the outside of the guide rod. A second moving block is slidably connected to the guide rod. A connecting rod is rotatably connected to the upper side of the second moving block. The upper side of the connecting rod is rotatably connected to the T-shaped block.

[0004] In the above scheme: the lower side of the T-shaped block is set as a cone, and the other side of the first moving block is provided with an inclined surface.

[0005] In the above scheme: a through hole is provided on the lower side of the T-shaped block, a damper is provided inside the through hole, and the lower side of the damper is connected to the lower wall of the vertical groove.

[0007] In the above scheme: a guide groove is provided inside the transverse groove, and the first moving block is slidably connected to the guide groove.

[0008] This utility model provides a side-tipping self-unloading cargo container, which has the following beneficial effects: 1. In this technical solution, the lifting power of the side-tipping self-unloading cargo box comes from the tractor vehicle, and it can be equipped with two lifting methods: manual lifting and remote control lifting. Manual lifting is performed by the tractor vehicle's power take-off and oil pump to the hydraulic cylinder, which can ensure unloading operations in case of power supply problems or special circumstances. Remote control lifting is performed by transmitting power from the tractor to the trailer's electric pump station, which eliminates the need for operators to manually operate near the vehicle and allows for convenient operation from a safe distance, greatly improving the flexibility and adaptability of lifting operations. 2. By evenly distributing multiple sets of buffer sections on the chassis, the buffer sections function when the vehicle is traveling on bumpy roads or when the cargo box is returning to its original position, reducing the impact of vibration on the chassis and underframe, preventing fatigue damage to the vehicle body structure due to long-term vibration, extending the service life of the vehicle body, and reducing maintenance costs.

[0012] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0013] Please see Figure 1-2 A side-tipping self-unloading cargo box includes a frame 1, a base frame 2 is provided on the upper side of the frame 1, a cargo box 3 is provided on the base frame 2, and hydraulic cylinders 4 are evenly arranged on the lower side of the base frame 2. The hydraulic cylinders 4 are installed upside down, and the driving end of the hydraulic cylinders 4 is connected to the lower side of the base frame 2. An electric pump station 5 is connected to the frame 1 by screws, and a buffer section is provided on the frame 1; The buffer part includes a base 6, a vertical groove is provided on the upper side of the base 6, a T-shaped block 7 is provided inside the vertical groove, and horizontal grooves are provided on both sides of the vertical groove. A first moving block 8 is provided inside the horizontal groove, and one side of the first moving block 8 is connected to the inner wall of the horizontal groove through a first spring 9. The base 6 has assembly slots on both sides, and a guide rod 10 is provided inside the assembly slot. A second spring 11 is sleeved on the outside of the guide rod 10. The guide rod 10 is slidably connected to a second moving block 12. A connecting rod 13 is rotatably connected to the upper side of the second moving block 12. The upper side of the connecting rod 13 is rotatably connected to the T-shaped block 7. It should be noted that in this case, the lifting power comes from the tractor unit, and two lifting methods are optional: manual lifting and remote control lifting. Manual lifting is performed by transmitting the power take-off and oil pump from the tractor unit to the hydraulic cylinder 4, which can ensure unloading operations in case of power supply problems or special circumstances. Remote control lifting, on the other hand, transmits the power from the tractor unit to the electric pump station 5 of the trailer for lifting. Operators do not need to operate manually near the vehicle and can operate conveniently from a safe distance, which greatly improves the flexibility and adaptability of lifting operations. Meanwhile, multiple sets of buffer sections are set on the top of the frame 1. When the vehicle is moving or the cargo box is reset, the cargo box will press down on the T-shaped block 7. During the pressing down of the T-shaped block 7, the damper 14 will be squeezed to perform initial buffering. At the same time, the T-shaped block 7 will push the second moving block 12 to move horizontally through the connecting rod 13. The guide rod 10 is used to increase the stability of the second moving block 12 and compress the second spring 11 to perform secondary buffering. Since the lower side of the T-shaped block 7 is tapered and the other side of the first moving block 8 is provided with an inclined surface, during the pressing down of the T-shaped block 7, the T-shaped block 7 will push the first moving block 8 to move horizontally and compress the first spring 9 to perform buffering again. This can prevent the bottom of the cargo box 3 from colliding with the frame 1 when the cargo box 3 is reset, thus preventing damage to the cargo box 3. It can also reduce the overall vibration of the cargo box 3 during driving and increase the service life of the cargo box 3. A rubber buffer pad 15 is provided on the upper side of the T-shaped block 7 to increase the buffering effect. A guide groove is provided inside the transverse groove. The first moving block 8 is slidably connected to the guide groove to increase the stability of the second moving block 12.
