Description

Technical Field

[0001] This utility model relates to the field of container unloading technology, specifically to a hydraulic device for container trucks. Background Technology

[0002] Currently, all bulk cargo carried in containers, such as bulk grains, distiller's grains, cement, chemical granules, and coal, needs to be further transferred to warehouses or other means of transport. In the traditional unloading process, loading and unloading workers need to wear special protective clothing to enter the container and use tools such as shovels to transfer the cargo out. In addition, powdery or granular bulk materials tend to clump together during long-distance transportation, making it very difficult to break them down manually. Therefore, traditional methods are time-consuming and labor-intensive and cannot meet the high-efficiency requirements of current industrial production.

[0003] Chinese Patent No. CN212098587U discloses a hydraulic device for a container truck, including a truck body and a container. A connecting plate is welded to the upper left side of the truck body. Fixing blocks are symmetrically installed on the front and rear sides of the upper left end of the connecting plate. Rotating rods are symmetrically installed at the upper center of the front and rear sides of the fixing blocks. A hydraulic cylinder is bolted to the middle right side of the upper surface of the connecting plate. The hydraulic output end of the hydraulic cylinder is connected to the hydraulic input end of the hydraulic telescopic rod. This invention uses a rotating groove penetrating the upper end of the fixing block. The rotating rods on the front and rear sides of the fixing block are fixedly connected to the central shafts of the bearings on the front and rear sides of the mounting groove, respectively, to further position the left end of the container. The guide rods are slidably connected through the sliding grooves on the front and rear sides of the guide groove, respectively, controlling the operation of the hydraulic cylinder. The hydraulic telescopic rod can push the guide rod to the right within the guide groove, further pushing the right end of the container to tilt for unloading.

[0004] However, the above technical solution has the following shortcomings: the hydraulic telescopic rod is directly and vertically installed between the vehicle body and the container. On the one hand, the center of gravity of the container and the vehicle body is relatively high, resulting in poor stability during vehicle operation. On the other hand, during the process of the hydraulic telescopic rod lifting the container, the force exerted on the vehicle body by the bottom of the hydraulic telescopic rod is too concentrated, and the local stress on the vehicle body is too large, which can easily cause damage to the vehicle body and pose a significant safety hazard. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a hydraulic device for container trucks.

[0006] The technical solution of this utility model is: a hydraulic device for a container truck, the hydraulic device being installed on the truck body; multiple buffer pads are provided on the top of the truck body; a container is rotatably mounted on the top of the truck body, and the hydraulic device includes:

[0007] A lifting mechanism, located at the bottom of the container, is used to rotate the container;

[0008] An adjustment mechanism, mounted on the vehicle body, is used to adjust the position of the lifting mechanism. One end of the adjustment mechanism is connected to the lifting mechanism via a transmission.

[0009] The self-locking mechanism is installed on the vehicle body to limit and fix the container. One end of the self-locking mechanism is interlocked with the container.

[0010] Preferably, the lifting mechanism includes a guide rail, a guide block, a telescopic rod, and a support plate; the guide rail is fixedly connected to the bottom of the container, the guide block is slidably connected to the guide rail, the telescopic rod is rotatably connected to the adjusting mechanism, one end of the telescopic rod is rotatably connected to the guide block, and the support plate is rotatably connected to the bottom end of the telescopic rod.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0016] This utility model, through the coordinated arrangement of the adjustment mechanism and the lifting mechanism, allows the lifting mechanism to be stored inside the vehicle body when not in operation, thereby lowering the center of gravity of the container and the vehicle body as a whole, thus improving the stability of the vehicle during driving. When the lifting mechanism is in operation, the bearing plate contacts the ground, transferring the force of the container on the telescopic rod to the ground, greatly reducing the stress on the vehicle body and thus reducing damage to the vehicle body.
