Description

Technical Field

[0001] The utility model relates to the field of logistics warehousing equipment, in particular to an integrated gear box frame. Background Art

[0002] Currently, conventional gearbox frame structures typically design the lifting gearbox and the traveling gearbox as two independent, unconnected components. While this design achieves functional separation to a certain extent, it also raises a series of unresolved issues. From the perspective of weight and range, traditional designs use heavy materials to ensure structural strength and stability, resulting in a significant increase in vehicle weight, which in turn affects the equipment's range. In today's world of increasing energy scarcity and growing environmental awareness, reducing equipment weight and improving range have become unresolved technical challenges. Secondly, regarding structural complexity and assembly processes, traditional gearbox frames consist of numerous components, making the assembly process cumbersome and demanding. This not only increases production costs but also reduces yield, hindering large-scale production and widespread application. Therefore, simplifying the structure and optimizing the assembly process are key to improving production efficiency and reducing costs. Furthermore, regarding space utilization, traditional designs often occupy a significant amount of vehicle body space due to the separate arrangement of the gearbox and frame, limiting the equipment's flexibility in compact environments. With the continuous optimization and increased utilization of storage and logistics space, higher demands are being placed on miniaturized and compact equipment. Finally, assembly precision is another major challenge facing traditional gearbox frames. The assembly between the gearbox assembly and the frame requires extremely high standards. However, the welding process used for the frame makes it difficult to ensure high-precision assembly with the gearbox assembly due to factors such as thermal deformation and difficulty in controlling dimensional accuracy. This not only affects the operational stability and reliability of the equipment but also increases subsequent maintenance and commissioning costs.

[0016] The structure and working principle of the present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 The first structural diagram of the integrated gearbox frame of the utility model, Figure 2 This is a second structural diagram of an integrated gearbox frame according to the present invention. Figure 3 This is an exploded view of the integrated gearbox frame structure described in the present invention. The integrated gearbox frame described in the present invention comprises a pair of lifting gearboxes 1, a pair of traveling gearboxes 2, and a frame outer frame. The pair of lifting gearboxes 1 are arranged transversely and parallel to each other, and the ends of the lifting gearboxes 1 are respectively connected to the corresponding ends of the traveling gearboxes 2, forming a rectangular structure.

[0018] The frame includes a pair of side frames 12, a front frame 13, and a rear frame 14; the travel gearbox 2 is fixedly mounted on the inner sides of the side frames 12. The frame also includes a pair of cross frames 11, which are arranged parallel to each other within the frame near the front and rear frames 13, 14. The lifting gearbox 1 is fixedly mounted on the inner sides of the cross frames 11. In a preferred embodiment of the present invention, the travel gearbox 1 is pinned to the inner sides of the side frames 12 via locating pins. Both the travel gearbox 2 and the side frames 12 are made of thin aluminum sheet material. This pinned connection ensures the accurate relative position of the travel gearbox and the side frames. Through precise hole alignment, the locating pins securely connect the two, preventing structural instability caused by loosening or displacement. This stable connection is particularly important in working environments subject to dynamic loads and vibration, effectively improving the overall strength and stability of the frame. When the frame is subjected to external loads, the locating pins effectively distribute the load across the contact surfaces between the travel gearbox and the side frames, avoiding stress concentration. This load distribution not only enhances the frame's load-bearing capacity but also reduces the risk of structural damage caused by localized excessive stress. Furthermore, the locating pins themselves possess a certain load-bearing capacity, further enhancing the overall strength of the frame. Over extended use, the frame may experience minor deformation due to various external forces. The locating pin connection effectively resists this deformation, maintaining the frame's precision and stability. The tight fit between the locating pins and holes ensures that even when subjected to certain external forces, the locating pins maintain the relative positions of the components, thereby ensuring the overall strength and precision of the frame. The locating pins also simplify the frame assembly process. Pre-fabricated holes and locating pins allow for quick connection between the travel gearbox and the side frames, eliminating the need for complex adjustments and calibration. This simplified assembly method not only improves production efficiency but also reduces human error and deviation during assembly, further ensuring the overall strength and stability of the frame.

[0019] The lifting gearbox 1 is made of thicker aluminum material, so as to ensure the strength of the fulcrum when lifting goods. In a preferred embodiment of the present invention, an upper cover plate 21 is provided on the top of the traveling gearbox 2. The upper cover plate 21 is specifically used to prevent external dust, moisture and debris from entering the interior of the traveling gearbox 2, thereby protecting the gears and transmission components from pollution and damage, and extending the service life of the traveling gearbox; at the same time, the tight connection between the upper cover plate 21 and the top of the traveling gearbox 2 can further enhance the structural strength of the entire gearbox, especially when bearing loads in the vertical direction, the upper cover plate can effectively disperse the pressure and improve the bearing capacity of the gearbox. The upper cover plate can also play a certain role in sound insulation, reduce the noise generated during the gear transmission process, and improve the comfort of equipment use. At the same time, it can also absorb and alleviate vibrations to a certain extent, protecting gears and bearings from excessive impact.

[0020] In a preferred embodiment of the present invention, the side frames 12 are provided with hollowed-out side frame holes; the cross frame 11 is provided with hollowed-out cross frame holes; the travel gearbox 2 is provided with hollowed-out travel gearbox holes corresponding to the hollowed-out side frame holes; and the lift gearbox 1 is provided with hollowed-out lift gearbox holes corresponding to the hollowed-out cross frame holes. The most direct advantage of these hollowed-out holes is that they can reduce the weight of the vehicle frame. By removing unnecessary material, the overall mass of the frame can be significantly reduced, which is crucial for improving vehicle energy efficiency, reducing energy consumption, and enhancing driving performance. Furthermore, in applications requiring frequent starts and stops, lightweight design can reduce energy loss and improve overall operating efficiency. In this utility model, despite the hollowing, the location, shape, and size of the hollowing are calculated during design to ensure that key parts of the frame maintain sufficient strength and rigidity. Hollowing holes are typically avoided in areas subject to significant loads or stresses, and instead are placed in non-critical areas or areas with less stress, thereby achieving weight reduction without sacrificing strength. The hollow through-hole design helps optimize the frame's structural layout and achieve a more balanced material distribution. By removing excess material, the strength of key areas can be more concentrated, improving the frame's overall performance. Furthermore, the hollow through-hole design increases the frame's surface area and airflow channels, helping to improve heat dissipation. During vehicle operation, components like the gearbox generate heat. The hollow design facilitates air circulation, dissipating heat, reducing component operating temperatures and extending service life.

[0021] The above is only an illustrative description of the present invention. Those skilled in the art should know that various improvements can be made to the present invention without departing from the working principle of the present invention, which all fall within the scope of protection of the present invention.
