Description

Technical Field

[0001] This utility model relates to the technical field of self-dumping semi-trailers, specifically to a reinforced semi-trailer side-tipping self-dumping truck body. Background Technology

[0002] Self-dumping semi-trailers use a hydraulic system to drive the cargo box to unload autonomously, and mainly include two operating modes: side tipping and rear tipping.

[0003] Chinese patent document CN220314827U discloses a side-tipping self-dumping box semi-trailer with a stable structure, including a truck bed and a semi-trailer body. The truck bed and the semi-trailer body are provided with a side-tipping structure. The side-tipping structure includes: a bottom groove, a connecting column, a support part, a support frame, a side-tipping hydraulic cylinder, and a locking part. The bottom groove is opened on the surface of the truck bed. The connecting column is located at the bottom of the semi-trailer body and is rotatably connected to the bottom groove by a pin. The support part is located at the bottom of the truck bed. The support frame is located on the bottom surface of the truck bed. The side-tipping hydraulic cylinder is rotatably connected between the semi-trailer body and the support frame by a pin. The locking part is located between the truck bed and the semi-trailer body.

[0004] In the above solution, a side-tipping structure and locking part are set between the truck bed and the semi-trailer box to achieve side-tipping unloading and stable transportation. However, the side-tipping structure and locking part are only located on one side of the two, which means that the semi-trailer box can only be tilted to unload in one direction and cannot be tilted to the other side. This one-way unloading mode seriously restricts the flexibility and efficiency of unloading operations. Especially in situations where the working space is limited, the vehicle position needs to be adjusted repeatedly, resulting in low convenience. Utility Model Content

[0016] Example 1; as Figure 1-3 As shown, the present invention proposes a reinforced semi-trailer side-tipping dump truck body, including a frame 1, a truck body 2 set at the top of the frame 1, a support assembly, a fixing assembly and a limiting assembly; The frame 1 has multiple hydraulic rods (prior art, not shown in the figure) that are connected to the middle of the bottom of the carriage 2 and move the carriage 2 upward in use. There are multiple support components, which are fixedly installed on both sides of the frame 1. The inner side of the end of the support component is provided with a connecting seat that connects to the carriage 2 and allows the carriage 2 to be tilted to the side in use. The fixing components are set inside the support components and connected to the connecting seats. The fixing components and the connecting seats of the support components are arranged one-to-one. Multiple fixing components on one side of the frame 1 are connected in series to form a group, so that the multiple fixing components on one side of the frame 1 can simultaneously fix and loosen the connecting seats on the support components. This allows the fixing components on both sides of the carriage 2 to be fixed and loosened respectively, thereby enabling the carriage 2 to be tilted to the sides respectively, improving the convenience of unloading. The number of limiting components is at least two. The two limiting components are respectively set at one end of the frame 1 and connected to the middle of the bottom of the carriage 2. They are used to move with the side roll of the carriage 2 during use, control the side roll angle of the carriage 2 within a safe range, effectively prevent the frame 1 from overturning due to excessive side roll angle, and ensure operational safety.

[0017] In this embodiment, the connecting seat is housed inside the support assembly by the carriage 2, and the fixing component is connected to the connecting seat inside the support assembly. The fixing component restricts the upward movement of the connecting seat inside the support assembly, while the support assembly restricts the lateral displacement of the connecting seat and makes the connecting seat rotatably connected to the fixing component and the support assembly. Thus, the carriage 2 is stably installed on the top of the frame 1 with the help of the cooperation of the fixing component and the support assembly. Then, the fixing components on both sides of the frame 1 are activated, so that the connecting seats on both sides of the carriage 2 are in the limited state and the relaxed state respectively. The hydraulic rod pushes the carriage 2 to lift along the top of the frame 1, so that the carriage 2 can be tilted to one side of the frame 1 for unloading based on the connecting seat. Then, the limited and relaxed states of the connecting seats on both sides are switched, so that the carriage 2 can be tilted to the other side of the frame 1 for unloading, thereby improving the convenience of unloading operations. In addition, through the cooperation of the limiting component, the tilting angle of the carriage 2 is controlled within a safe range, effectively avoiding the overturning of the frame 1 due to the excessive tilting angle, and ensuring operational safety.

[0018] Example 2; as Figure 2 As shown, the present invention proposes a reinforced semi-trailer side-tipping dump truck body. Compared with embodiment one, the difference in this embodiment is that the connecting seat includes a connecting plate 3 and a rotating shaft 8. The connecting plate 3 is installed at the bottom of the carriage 2; The rotating shaft 8 is located on the side of the connecting plate 3.

[0019] In this embodiment, the rotating shaft 8 is installed on the bottom side of the carriage 2 by the connecting plate 3, and the connecting plate 3 drives the rotating shaft 8 to rotate and connect with the support assembly. At the same time, the rotating shaft 8 is limited by the fixing assembly, so that the position of one side of the carriage 2 is limited. Thus, when the carriage 2 is overturned, the carriage 2 drives the rotating shaft 8 to rotate in the support assembly through the connecting plate 3, so that the carriage 2 can perform the side overturning unloading operation according to the rotating shaft 8.

[0020] Example 3; as Figure 2 As shown, the present invention proposes a reinforced semi-trailer side-tipping dump truck body. The difference between this embodiment and the first embodiment is that the support assembly includes a support rod 5 and a support block 4. The support rod 5 is installed on the side of the frame 1 and located below the carriage 2. The bottom end of the support rod 5 is equipped with a reinforcing rib to improve the support strength of the support rod 5. There are two support blocks 4, which are symmetrically installed on the inner side of the end of the support rod 5. The surface of each support block 4 has a U-shaped groove. The groove of the support block 4 is adapted to the diameter and movement trajectory of the rotating shaft 8, so that when the carriage 2 rotates the rotating shaft 8 on one side inside the groove, the rotating shaft 8 on the other side moves in and out of the groove of the other support block 4. This makes the installation of the rotating shaft 8 more convenient. The top of one end of the support rod 5 and the top of one side of the support block 4 are both provided with rounded corners 12 to prevent the support blocks 4 and support rod 5 from contacting the bottom of the carriage 2 during use, thus preventing the carriage 2 from tipping over. The depth of the groove is greater than the diameter of the rotating shaft 8, so that the support blocks 4 limit the lateral movement of the rotating shaft 8 and the connecting plate 3, thereby improving the stability of the carriage 2 during transportation. The other side of the support block 4 is provided with a socket 14, and the end of the fixing component is located inside the socket 14 and connected to the rotating shaft 8.

[0021] In this embodiment, the support block 4 is installed at the bottom of the carriage 2 by the support rod 5 and rotatably connected to the rotating shaft 8, and the rotating shaft 8 is placed inside the groove of the support block 4, so that the support block 4 limits the rotating shaft 8 and allows the rotating shaft 8 to rotate inside the support block 4. When the carriage 2 overturns, the rotating shaft 8 is supported by the cooperation of the support block 4 and the support rod 5.

[0022] Example 4; as Figure 2 As shown, the present invention proposes a reinforced semi-trailer side-tipping dump truck body. Compared with embodiment one, the difference in this embodiment is that the fixing component includes a limiting rod 9, a mounting block 10, and a telescopic rod 11. The telescopic rod 11 is installed inside the support rod 5 and on the other side of the support block 4, with its extended end facing the support block 4; Mounting block 10 is installed at the extended end of telescopic rod 11; The limiting rod 9 is set on the side of the mounting block 10 and its end is inserted into the inner side of the insertion hole 14 and connected to the rotating shaft 8. The limiting rod 9 and the support block 4 are arranged one-to-one. The bottom of one end of the limiting rod 9 is provided with an inclined surface 13, which is used to make the limiting rod 9 contact the rotating shaft 8 to have a guiding effect and avoid the end of the limiting rod 9 from obstructing the rotating shaft 8.

[0023] In this embodiment, the telescopic rod 11 extends towards the frame 1 through its extended end, allowing the telescopic rod 11 to drive the limiting rod 9 to be inserted into the inner side of the insertion hole 14 via the mounting block 10. The limiting rod 9 is positioned above the rotating shaft 8 and connected to the rotating shaft 8, thus limiting the position of the rotating shaft 8. This allows the limiting of the rotating shaft 8 on both sides of the carriage 2 to be flexibly adjusted by the telescopic rod 11, enabling the carriage 2 to be tilted to both sides of the frame 1, thereby improving the convenience of unloading.

[0024] Example 5; as Figure 3As shown, the present invention proposes a reinforced semi-trailer side-tipping dump truck body. Compared with embodiment one, the difference in this embodiment is that the limiting component includes a connecting rod 6, a mounting plate 7, and a fixing plate 15. Mounting plate 7 is mounted on frame 1; There are two fixing plates 15, which are respectively installed in the middle of the mounting plate 7 and the carriage 2; There are two connecting rods 6. One end of each connecting rod 6 is rotatably connected to the fixed plate 15, and the other ends of the two connecting rods 6 are rotatably connected to each other. The total length of the two connecting rods 6 is less than or equal to the height of the middle of the carriage 2 at the maximum safe rollover angle, so that the carriage 2 is always within the safe rollover angle.

[0025] In this embodiment, the carriage 2 drives a fixed plate 15 to move upward, which in turn drives a connecting rod 6 to move upward. The two ends of the connecting rod 6 rotate with the fixed plate 15 and the end of the other connecting rod 6, and the end of the other connecting rod 6 rotates on another support rod 5. This makes the two connecting rods 6 parallel to each other, achieving the maximum safe rollover angle of the carriage 2. This keeps the rollover angle of the carriage 2 within a safe range, effectively preventing the frame 1 from overturning due to an excessive rollover angle and ensuring operational safety.

[0026] In this invention, the rotating shaft 8 is installed on the bottom side of the carriage 2 via the connecting plate 3, and the carriage 2, through the connecting plate 3, causes the rotating shaft 8 to be housed inside the groove of the support block 4. Simultaneously, the extended end of the telescopic rod 11, through the mounting block 10, causes the limiting rod 9 to be inserted into the insertion hole 14, placing the limiting rod 9 above the rotating shaft 8 and connecting it to the rotating shaft 8, thus limiting the position of the rotating shaft 8. This fixes the carriage 2 to the top of the frame 1, enabling stable transport. Simultaneously, activating the telescopic rod 11 on one side of the frame 1 separates the limiting rod 9 from the rotating shaft 8, and a hydraulic rod drives the carriage 2 upwards, causing the carriage 2, through the connecting plate 3 on the other side, to move the rotating shaft 8 onto the frame. The support block 4 on the other side rotates, causing the carriage 2 to tilt and unload to the other side of the frame 1. By adjusting the position of the limit rods 9 on both sides of the frame 1, the position of the pivot 8 on the other side of the frame 1 is limited, thereby allowing the carriage 2 to tilt and unload to one side of the frame 1, improving the unloading convenience of the carriage 2. At the same time, by matching the length of the two connecting rods 6 with the maximum upward height of the middle of the carriage 2, when the two connecting rods 6 are placed parallel to each other by the fixing plate 15, the carriage 2 is at the maximum safe tilt angle, thereby controlling the tilt angle of the carriage 2 within a safe range, effectively preventing the frame 1 from overturning due to excessive tilt angle, and ensuring operational safety.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
