Description

Technical Field

[0001] The utility model belongs to the technical field of straddle carriers, and in particular relates to a frame of a straddle carrier. Background Art

[0002] With the rise of the energy storage industry, straddle carriers have become the mainstream method for transporting energy storage containers. Existing straddle carriers are primarily developed for the logistics industry and are generally used outdoors. However, lifting energy storage containers is often done within factories, where space is limited. The existing straddle carriers' long diagonal beam frames cannot meet space requirements, and the existing straddle carrier frames cannot withstand large loads, limiting their load-carrying capacity. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is a detailed description of the present invention with reference to the accompanying drawings. Figure 1-3 , the present invention is further described in detail. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0019] The present invention provides a straddle carrier frame, comprising a main frame, with extension frames symmetrically provided at the left and right ends of the main frame, the extension frames comprising a load-bearing beam 2 and a support base connected to the main frame, the support base being provided at the bottom ends of the load-bearing beam 2, the support base comprising a transverse plate 7 provided at the lower end of the load-bearing beam 2 and a curved beam 8 for supporting the transverse plate 7. The provision of the curved beam can effectively shorten the length of the supporting transverse plate, thereby shortening the strength of the straddle carrier's overall frame, making it suitable for smaller spaces within a factory building while providing good strength to prevent damage during lifting. Reinforcing ribs 13 are welded to the connection between the curved beam 8 and the main frame to increase the strength of the connection. Cylinder mounting holes are provided on the curved beam to facilitate the installation of the cylinder.

[0020] The main frame includes four vertical beams 4, which are arranged in a square shape. The left and right ends of the main frame include a cross beam 1, and the two ends of the cross beam 1 are respectively connected to the vertical beam 4. The front and rear ends of the main frame are provided with an upper beam 11, and the two ends of the upper beam 11 are connected to the vertical beam 4. The lower end of the upper beam 11 is provided with a lower beam 5. The connection of the main frame is provided with reinforcing ribs 13, and double beams are provided at the front and rear ends. At the same time, the reinforcing ribs 13 provided at the connection can effectively improve the strength of the main frame, thereby increasing the bearing capacity of the frame.

[0021] The load-bearing beam 2 is provided with a lifting pulley to facilitate lifting the energy storage box.

[0022] The upper beam is provided with an oil cylinder supporting plate 12 and an oil cylinder mounting base 6 to facilitate the installation of the oil cylinder.

[0023] The vertical beam 4 extends upward to form a reinforced end, and a reinforcement plate is provided at the connection between the vertical beam 4, the horizontal beam 1 and the support base. The provision of the reinforcement plate enhances the connection strength between the extension frame and the main frame.

[0024] The design of this extension frame allows the frame to fit into smaller factory spaces while maintaining strength, making it particularly useful in space-constrained warehouses or factories. By using curved beams and support cross plates, the length of the support cross plates is shortened, reducing the weight of the frame while maintaining the required strength. The presence of reinforcing ribs and reinforcement plates enhances the stability and durability of the entire frame. Cylinder mounting holes are provided on the curved beams, simplifying the installation of equipment such as cylinders and improving installation efficiency. This maximizes space utilization, reducing the space occupied by cylinder installation, and further shortening the frame length.
