Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a dump truck body with a side-tilting and sealed design. Background Technology

[0002] With rapid economic growth and increased freight volume, users have placed higher demands on vehicle load capacity. Given a fixed total mass, a lighter curb weight allows for a larger load capacity and higher economic efficiency. However, traditional dump trucks currently on the market suffer from the following problems:

[0003] 1. Most dump truck side panel structures are either grid side panels or double V side panels. Grid side panels have more ribs, are heavier, have more welds, and are more prone to welding deformation. V-shaped side panel structures have lower side panel strength and are more prone to material accumulation and box expansion, which can no longer meet the needs of users.

[0004] 2. Traditional dump trucks generally do not have sealed covers. During transportation, construction waste and slag are easily spilled, causing serious environmental pollution and posing a safety hazard to other vehicles and pedestrians.

[0005] 3. Traditional dump trucks generally have a front-mounted lifting mechanism and unloading at the rear of the cargo box. The height of the lifting strut is limited by the length of the cargo box. The longer the cargo box, the longer the strut is required. However, the strut is designed to increase in height in stages, and the top is relatively thin, resulting in poor lateral stability. During the unloading process, the cargo box is very prone to tilting. In addition, when the weight of the transported material is large, it is very likely to overturn with the entire vehicle body, which is very dangerous. The unloading speed is also very slow, and the unloaded material can easily scratch the vehicle tires.

[0006] 4. Traditional dump truck lifting uses pneumatic-driven hydraulic control, which leads to problems such as reduced stability, increased failure rate, and low work efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a dump truck body structure that can solve the problems of existing dump truck bodies having too many ribs in the side plate structure, heavy weight or low side plate strength, easy material accumulation and box expansion, and front lifting where the height of the lifting rod is limited by the length of the box, resulting in poor lateral stability. During the unloading process, the box is prone to tilting and the unloaded material can easily scratch the vehicle tires.

[0030] The container 1 is a movable loading hopper formed by an assembly 10 consisting of a bottom plate, a front plate, a rear plate, a left side plate, and a right side open plate. The front and rear plates are each welded to one end of the left side plate; the bottom ends of the front, rear, and left side plates are all welded to the bottom plate. Figure 3 and Figure 4 As shown, at least five sets of matching flip pins and flip pin sleeves 10-1 are spaced apart on the bottom side of the right side opening plate assembly 10, and sealing plates 10-2 that fit against the front and rear plates are provided on both sides; the bottom side of the right side opening plate assembly 10 is hinged to the bottom plate through flip pin sleeves and flip pins. Bottom plate hinge ears 3 are provided at the front, middle, and rear of the right side of the bottom plate, and the bottom plate of the box body 1 is hinged to the chassis 4 through the bottom plate hinge ears 3 and the hinge shaft. The upper middle part of the front and rear ends of the box body 1 is hinged to the cylinder body of a discharge driving hydraulic cylinder 7; the middle parts of the front and rear sides of the right side opening plate assembly 10 are hinged to the piston rods of a discharge driving hydraulic cylinder 7. The upper left ends of the front and rear ends of the box body 1 are hinged to the piston rods of a box body driving hydraulic cylinder 5; the cylinder body of the box body driving hydraulic cylinder 5 is hinged to the chassis 4 of the vehicle body. The top center of each side of the top of the top cover welding assembly 2 is hinged to one end of a straight connecting rod 6, and the other end of the straight connecting rod 6 is hinged to the upper left side of the front and rear end plates of the housing 1. The top cover 2-1 of the top cover welding assembly 2 is arc-shaped, and the two sides of the top cover welding assembly 2 are hinged to one end of a curved connecting rod 9, and the other end of the curved connecting rod 9 is hinged to the upper left side of the front and rear end plates. The lower middle part of the curved connecting rod 9 is hinged to the piston rod of the top cover drive hydraulic cylinder 8, and the cylinder body of the drive hydraulic cylinder 8 is hinged to the right side of the front and rear end plates.

[0031] The body drive hydraulic cylinder 5 is responsible for driving the entire body to tilt to the right for unloading. The specification of the body drive hydraulic cylinder 5 is DA150 / 100-1045-k1500-B60P60. The unloading drive hydraulic cylinder 7 drives the side opening plate to open and close for unloading. The specification of the unloading drive hydraulic cylinder 7 is DA110 / 85-995-k1358-B50P50. The top cover drive hydraulic cylinder 8 drives the opening and closing of the top cover welding assembly 2.

[0034] The bottom of the container is connected to the chassis by three axles, and the bottom plate and side opening plate of the container are connected by a rotating fulcrum. Two sets of hydraulic tilting devices are installed to control the tilting process. During the tilting process, the weight of the material is evenly distributed to the side of the container, reducing the possibility of the vehicle being crushed. At the same time, the width of the unloading port is increased several times, which effectively improves the unloading speed. Due to the stability of the structure, the driver does not even need to stop. After reaching the destination, the driver only needs to slow down and unload the material while the vehicle is in motion, which further improves the unloading efficiency and reduces transportation costs.
