[0002] Self-tipping trucks are specialized transport equipment widely used in industries such as mining, metallurgy, and building materials. Their cargo compartments can rotate around the longitudinal axis of the vehicle via hydraulic or mechanical devices to achieve lateral unloading of materials. Due to their high loading and unloading efficiency and ease of operation, they hold an important position in the field of bulk material transfer. However, traditional self-tipping trucks generally have a serious risk of overturning in actual operation. When the cargo compartment rotates to a large-angle unloading position, the vehicle's center of gravity shifts significantly to the outside of the support surface, leading to overturning. Therefore, we propose a self-tipping truck anti-overturning device. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example 1

[0029] A self-tipping anti-rollover device, such as Figures 1-5 , Figure 7 , Figure 8 As shown, it includes a frame 1; the frame 1 is equipped with a protective mechanism 2, which can protect the device and prevent the frame 1 from tipping over due to the change in the center of gravity of the loaded material during self-tipping unloading.

[0030] Specifically, the protective mechanism 2 includes a carriage 21, which is rotatably connected to the frame 1. A bracket 22 is fixedly connected to the bottom of the carriage 21, and a column 23 is movably connected to the bracket 22. The carriage 21 can carry materials and perform a self-tipping unloading operation by rotating on the frame 1. The bracket 22 is fixedly connected to the bottom of the carriage 21 and can support and position the column 23. At the same time, the column 23 can slide on the bracket 22 to adjust its position and support the carriage 21 through the bottom of the column 23, reducing the risk of the carriage 21 overturning.

[0031] Furthermore, the bracket 22 is provided with a positioning groove 24, which runs through the bracket 22. The positioning groove 24 corresponds to the structure of the column 23. The bracket 22 is provided with a circular through hole 25 that runs through both ends. The positioning groove 24 allows the column 23 to slide easily, allowing the column 23 to switch between different positions. The circular through hole 25 can cooperate with the top of the column 23. When the carriage 21 rotates to unload materials, the top of the column 23 can support the carriage 21 and prevent the carriage 21 from overturning.

[0032] Based on this, the top of the column 23 has an arc-shaped structure, and support columns 26 are fixedly connected to both sides of the column 23. The structure of the support column 26 corresponds to the structure of the through hole 25. The top of the arc-shaped column 23 and the support columns 26 on both sides of the column 23 can cooperate with the inner side of the circular through hole 25 to improve the support effect on the carriage 21.

[0033] In addition, a door 27 is rotatably connected to one side of the carriage 21. A limit frame 28 is fixedly connected to the door 27. The limit frame 28 has a ring structure and corresponds to the structure of the column 23. The door 27 can shield the side of the carriage 21 to prevent materials from spilling during transportation. The limit frame 28 can cooperate with the column 23 and limit the rotation of the door 27 through the column 23.

[0034] Example 2

[0035] like Figure 1 , Figures 3-8 As shown, based on Embodiment 1, the frame 1 is provided with a drive mechanism 3, which can drive the protective mechanism 2 and automatically open the protective mechanism 2 when the self-tilting unloading is performed.

[0036] In this embodiment, the drive mechanism 3 includes a support frame 31, which is rotatably connected to the frame 1. A hydraulic cylinder 32 is fixedly connected to the bracket 22. The output end of the hydraulic cylinder 32 is rotatably connected to the bottom of the carriage 21. The support frame 31 can support the hydraulic cylinder 32, and the hydraulic cylinder 32 can drive the carriage 21 so that the carriage 21 can be flipped on the frame 1.

[0037] It is worth noting that a positioning rod 33 is slidably connected inside the carriage 21. One end of the positioning rod 33 passes through the column 23. The side of the column 23 has a positioning hole 34 that corresponds to the structure of the positioning rod 33. The positioning rod 33 can position the column 23 and limit the rotation of the door 27 during the transportation of the frame 1, while preventing the column 23 from being damaged due to sliding down due to gravity.

[0038] Furthermore, a drive rod 35 is connected to the other end of the positioning column. Both ends of the drive rod 35 are fixedly connected to buffer springs 36. The ends of the buffer springs 36 are fixedly connected to the carriage 21 and the positioning rod 33, respectively. A steel cable 37 is fixedly connected to the end of the drive rod 35. A positioning hook 38 is fixedly connected to the end of the steel cable 37. The structure of the drive rod 35 can drive the positioning rod 33, so that the positioning rod 33 can be moved out of or inserted into the interior of the column 23. At the same time, the structure of the steel cable 37 can provide auxiliary protection for the end of the carriage 21 through the structure of the positioning hook 38, further reducing the risk of the carriage 21 overturning.

[0039] In use, the self-tipping anti-tipping device of this utility model first pulls the steel cable 37 away from the carriage 21 and fixes the steel cable 37 in a preset position by the positioning hook 38. Due to the pulling of the steel cable 37, the positioning rod 33 moves out of the positioning groove 24 on the column 23, causing the column 23 to move downward without the restriction of the positioning rod 33. The column 23 and the support column 26 then move into the through hole 25, and the door 27 is no longer limited by the column 23. After opening the latches on both sides of the door 27, the door 27 can be rotated to perform the material unloading operation. During material unloading, the hydraulic cylinder 32 is activated and pushes the carriage 21 to tip over, and the material inside the carriage 21 is unloaded through the opened door 27. Meanwhile, as the support 22 rotates with the carriage 21, the positioning groove 24 on the support 22 gradually tilts from a vertical position. Due to the gravity at the bottom and the support of the top support column 26, the column 23 remains vertical. Therefore, the top of the column 23 gradually deviates from the positioning groove 24. Since the support 22 is located on the side away from the hydraulic cylinder 32 and the support 22 is a certain distance from the rotation axis, the support 22 gradually approaches the ground as the carriage 21 rotates. The column 23 also gradually approaches the ground as the support 22 rotates. After the top of the column 23 is misaligned with the positioning groove 24, it cooperates with the inside of the support 22. Finally, the end of the column 23 contacts the ground and supports the entire carriage 21 through the column 23. As the carriage 21 tilts, the distance between the carriage 21 on the side of the hydraulic cylinder 32 and the frame 1 gradually increases. The steel cable 37 is fixed to the ground by the positioning hook 38. Therefore, when the carriage 21 rotates to the set maximum angle, the steel cable 37 can limit the end of the carriage 21, preventing it from tipping over under the pressure of the material. Simultaneously, since the rotation axis is located on the side of the frame 1 away from the hydraulic cylinder 32, the lever arm of the carriage 21 on the side of the steel cable 37 is longer than that on the side of the support 22. Therefore, the steel cable 37 only requires a small pulling force to prevent the carriage 21 from tipping over. After the unloading operation is completed, the hydraulic cylinder 32 drives the carriage 21 to reset. The drive rod 35 moves to the other end under the action of the buffer spring 36, and pulls the steel cable 37 back into the carriage 21. After closing the door 27, the column 23 is inserted into the limiting frame 28 to proceed with the subsequent loading operation.
