Description

Technical Field:

[0001] The utility model relates to the technical field of hydraulic truck unloaders, in particular to a high-strength hydraulic truck unloading platform. Background Art:

[0002] The hydraulic truck unloading platform, also called a tipping platform, is one of the important components in a hydraulic truck unloader. Usually, one end of the hydraulic truck unloading platform is rotatably connected to a support on the foundation, and the other end lies horizontally on the foundation. A wheel stopper is provided on the hydraulic truck unloading platform, and an oil cylinder is rotatably provided on the foundation. The oil cylinder is rotatably connected to the hydraulic truck unloading platform. Under the action of the oil cylinder, the hydraulic truck unloading platform and the transport vehicle thereon are turned backward for discharging. Since the hydraulic truck unloading platform not only needs to bear heavy loads but also the lifting impact force from the unloading hydraulic cylinder, it is required that the hydraulic truck unloading platform has high strength and can withstand heavy loads and lifting impact forces.

[0003] The existing hydraulic truck unloading platform has a relatively simple structure. It is mainly composed of a main frame welded by multiple longitudinally and horizontally arranged steel pipes or I-beams, and then a steel plate is welded to the upper end of the main frame to form a platform. Then, components such as a platform rotating shaft, a wheel stopper, and an oil cylinder support are welded and installed on the main frame as needed. The application of the existing hydraulic truck unloading platform has promoted the development of hydraulic truck unloaders. However, with the popularization and application of the existing hydraulic truck unloading platform, some deep-seated technical problems have been found. One is that after the steel plate at the upper end of the platform has been used for a period of time, deep indentations are left at the positions corresponding to the wheels passing through. As the indentations deepen, the steel plate will be severely deformed, and even the welded joints of the steel plate will be opened, posing a great safety hazard. The other is that the steel plate for installing the support or the steel beam connected to it sometimes deforms. This is mainly because the support needs to bear the lifting impact force from the oil cylinder, and the support itself has high strength. Therefore, usually, the impact force acts on the steel plate or steel beam for installing the support. Therefore, it is necessary to optimize the design of the existing hydraulic truck unloading platform, especially to strengthen the design of the areas where the platform is subjected to large forces.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model:

[0030] As Figure 1-6 shown, a high-strength hydraulic truck unloading platform includes two main crossbeams 1 arranged at longitudinal intervals. Steel plates 2 are provided at the upper ends of the two main crossbeams 1. Side longitudinal beams 3 are respectively provided at both ends between the two main crossbeams 1. At least one intermediate longitudinal beam 4 is provided between the two side longitudinal beams 3. Both ends of the intermediate longitudinal beam 4 are arranged on the main crossbeam 1. A support 5 is provided on one side of the intermediate longitudinal beam 4. A plurality of support longitudinal beams 6 are arranged at lateral intervals between the two main crossbeams 1. A plurality of support crossbeams 7 are arranged at longitudinal intervals between the side longitudinal beam 3 and the intermediate longitudinal beam 4. The upper ends of the support crossbeams 7 are used to support the steel plate 2, and the lower ends are arranged on the support longitudinal beams 6. Two support crossbeams 7 are arranged at intervals corresponding to the area 8 where the wheels pass. By arranging two support crossbeams 7 in the area 8 where the wheels pass, the structural strength of this area can be significantly improved, making it not easy for the area 8 where the wheels pass to deform; by arranging the intermediate longitudinal beam 4 and the support crossbeams 7 connecting the intermediate longitudinal beam 4 and the side longitudinal beam 3, the structure of the intermediate longitudinal beam 4 is strengthened. The support 5 arranged on the intermediate longitudinal beam 4 is not only convenient for installation but also has strong overall impact resistance. The support 5, the wheel stopper 13 and the platform spindle 14 in this application belong to the prior art and are widely used in existing hydraulic truck unloading platforms. The main innovation point of this application is to improve the overall installation structural strength through the structural improvement of the platform itself. The connection and provision in this application mainly refer to being realized in the form of welding.

[0031] The main crossbeam 1, the side longitudinal beam 3 and the intermediate longitudinal beam 4 are made of H-shaped steel. Using H-shaped steel has the advantages of mature technology and high structural strength.

The two ends of the side longitudinal beams 3 and intermediate longitudinal beams 4 are respectively provided with web protrusions A9, and the web protrusions A9 are inserted between the upper and lower flange plates of the main cross beam 1. The use of H-shaped steel with the same specifications for the main cross beam 1, side longitudinal beams 3 and intermediate longitudinal beams 4 not only strengthens the main support structure, but also facilitates design and mass production due to the same specifications, with strong versatility. At the same time, by designing the web protrusion A9, the upper ends are flush (i.e., the upper flange plates are flush), making it convenient and neat to install the steel plate 2.

[0033] The support longitudinal beams 6 and support cross beams 7 are made of I-shaped steel, and the two ends of the support longitudinal beams 6 are arranged on the webs of the main cross beam 1. Using I-shaped steel has the advantages of mature technology and high structural strength.

[0034] Reinforcing plates A10 are vertically arranged at intervals between the upper and lower ends of the support longitudinal beam 6 and the main cross beam 1. By designing the reinforcing plates A10, the connection between the support longitudinal beam 6 and the main cross beam 1 is strengthened.

[0035] Web protrusions B11 are respectively provided at both ends of the support cross beam 7, and the web protrusions B11 are inserted between the upper and lower flange plates of the side longitudinal beam 3 or intermediate longitudinal beam 4.

[0036] A plurality of reinforcing plates B12 are vertically arranged at intervals between the web of the main cross beam 1 and the web of the intermediate longitudinal beam 3. By designing the reinforcing plates B12, the connection strength between the intermediate longitudinal beam 3 and the main cross beam 1 is significantly enhanced.

[0037] A plurality of wheel stoppers 13 are arranged between the two main cross beams 1, and support longitudinal beams 6 are respectively arranged on both sides of the wheel stoppers 13. By respectively designing the support longitudinal beams 6 on both sides of the wheel stoppers 13, it is beneficial to improve the structural strength of this area.

[0038] One end between the two main crossbeams 1 is provided with a side longitudinal beam A301, and the other end is provided with a side longitudinal beam B302. An intermediate longitudinal beam A401 is provided between the side longitudinal beam A301 and the side longitudinal beam B302. A support 5 is provided on one side of the intermediate longitudinal beam A401 close to the side longitudinal beam A301, and an intermediate longitudinal beam B402 is provided on the other side. A platform spindle 14 is provided at one end of the two main crossbeams 1 where the side longitudinal beam A301 is located. Support steel pipes 15 are respectively provided on the lower wing plates inside the side longitudinal beam A301 and the side longitudinal beam B302, and on the lower wing plate of the intermediate longitudinal beam B402 close to the side longitudinal beam B302. A plurality of support rib plates 16 are provided on the web of the intermediate longitudinal beam A401 close to the side longitudinal beam A301. One end of a support crossbeam 7 located between the side longitudinal beam A301 and the intermediate longitudinal beam A401 is arranged on the support steel pipe 15, and the other end is arranged on the support rib plate 16. Both ends of the support crossbeam 7 located between the side longitudinal beam B302 and the intermediate longitudinal beam B402 are respectively arranged on the support steel pipe 15. By designing the support steel pipe 15 and the support rib plate 16, the end support of the support crossbeam 7 is realized, and the bearing capacity of the support longitudinal beam 7 is significantly improved in cooperation with the support longitudinal beam 6.
