Description

Technical Field

[0001] The invention relates to the field of logistics storage equipment, and in particular to an integrated gear box frame. Background Art

[0002] At present, the traditional gearbox frame structure of the background technology usually designs the lifting gearbox and the traveling gearbox as two independent and unconnected components. Although this design has achieved functional differentiation to a certain extent, it has also caused a series of problems to be solved. From the perspective of weight and endurance, the traditional design uses heavy materials to ensure structural strength and stability, resulting in a significant increase in the weight of the whole vehicle, which in turn affects the endurance of the equipment. At present, with the increasing shortage of energy and the increasing awareness of environmental protection, how to reduce the weight of the equipment and improve the endurance performance has become a technical problem to be solved. Secondly, in terms of structural complexity and assembly process, the traditional gearbox frame is composed of many parts, and its assembly process is cumbersome and has high process requirements. This not only increases the production cost, but also reduces the yield rate, which is not conducive to large-scale production and promotion and application. Therefore, simplifying the structure and optimizing the assembly process have become the key to improving production efficiency and reducing costs. Furthermore, in terms of space utilization, the traditional design often occupies a large amount of vehicle body space due to the separate setting of the gearbox and the frame, which limits the application flexibility of the equipment in a compact environment. With the continuous optimization and improvement of the utilization rate of storage and logistics space, higher requirements are put forward for the miniaturization and compactness of equipment. Finally, assembly accuracy is also a major challenge faced by traditional gearbox frames. The assembly requirements between the gearbox assembly and the frame are extremely high, but the welding process used in the frame is 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 operating stability and reliability of the equipment, but also increases the cost of subsequent maintenance and debugging.

[0003] In view of the problems existing in the prior art, it is of great significance to provide an integrated gearbox frame. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an integrated gear box frame.

[0005] To achieve the above-mentioned purpose, the integrated gearbox frame of the present invention comprises a pair of lifting gearboxes, a pair of traveling gearboxes and a frame outer frame, wherein the pair of lifting gearboxes are arranged in parallel with each other, and the ends of the lifting gearboxes are respectively connected to the corresponding ends of the traveling gearboxes in pairs to form a rectangular structure; the frame outer frame comprises a pair of side frames, a front frame and a rear frame; the traveling gearbox is fixedly arranged on the inner side of the side frames;

[0006] It also includes a pair of cross frames, which are respectively arranged in parallel inside the frame outer frame near the front frame and the rear frame, and the lifting gear box is fixedly arranged on the inner side of the cross frames;

[0007] It also includes an upper sealing plate, which is arranged on the top of the travel gear box;

[0008] The side frame is provided with a side frame hollow through hole; the travel gear box is provided with a travel gear box hollow through hole corresponding to the side frame hollow through hole;

[0009] The horizontal frame is provided with a hollow through hole of the horizontal frame; the lifting gear box is provided with a hollow through hole of the lifting gear box corresponding to the hollow through hole of the horizontal frame;

[0010] The travel gear box is specifically pin-connected to the inner side of the side frame through a positioning pin;

[0011] The travel gear box and the frame outer frame are made of aluminum sheet material.

[0012] The integrated gearbox frame of the present invention forms an integrated rectangular structure design with the lifting gearbox, the traveling gearbox and the frame outer frame, which brings significant technical effects and performance improvements in many aspects: first, the optimization of the frame weight and the improvement of the endurance: in the traditional design, the gearbox and the frame are independent components, which often require more connectors and support structures, resulting in a large overall weight. However, the present invention effectively reduces redundant components through an integrated design, adopts lightweight materials and an optimized structural layout, and significantly reduces the weight of the frame. This change not only reduces the burden of the entire vehicle, but also directly improves the endurance of the terminal product, so that the equipment can perform longer operating tasks under a single charge or fuel replenishment, greatly improving work efficiency and operating economy; secondly, the overall space utilization of the vehicle body is improved and the selection range of internal components is expanded: the integrated design makes the lifting gearbox, the traveling gearbox and the frame outer frame closely combined, effectively eliminating the space waste caused by the gap between components in the traditional design. This compact layout not only improves the space utilization of the vehicle body, but also provides greater flexibility for the selection of internal components. Designers can choose smaller and higher-performance components according to actual needs, which further promotes the miniaturization and intelligent development of equipment; secondly, the improvement of frame accuracy and the significant improvement of supplier yield rate: the present invention adopts integrated processing and manufacturing technology to ensure the precise matching and positioning of various components of the frame. Compared with the traditional welding or bolt connection method, the integrated design reduces the accuracy problems caused by processing errors and assembly deviations, so that the overall accuracy of the frame has been significantly improved. This change is directly reflected in the supplier's yield rate, reducing rework and scrapping due to substandard accuracy, reducing production costs, and improving production efficiency and product quality; finally, the optimization of assembly process and the significant improvement of assembly efficiency: the integrated design simplifies the assembly process, reduces assembly steps and required tools, and makes the assembly process more efficient and quick. Through pre-assembly or modular production methods, the assembly cycle can be greatly shortened and the production efficiency of the assembly line can be improved. In addition, the integrated design also reduces the requirements for the skill level of assembly workers, reduces human errors, and further ensures the consistency of assembly quality and products. In summary, the integrated gearbox frame of the present invention, through its unique technological innovation, achieves the optimization of frame weight, the improvement of endurance, the improvement of space utilization, the enhancement of frame precision and the optimization of assembly process, providing a more efficient, reliable and economical solution for logistics, warehousing, construction machinery and other fields.

[0016] The structure and working principle of the present invention are further described below in conjunction with the accompanying drawings.

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

[0018] The frame outer frame includes a pair of side frames 12, a front frame 13 and a rear frame 14; the travel gear box 2 is fixedly arranged on the inner side of the side frame 12. The frame outer frame also includes a pair of cross frames 11, which are respectively arranged in parallel at positions near the front frame 13 and the rear frame 14 inside the frame outer frame, and the lifting gear box 1 is fixedly arranged on the inner side of the cross frame 11. In a preferred embodiment of the present invention, the travel gear box 1 is pinned to the inner side of the side frame 12 by means of locating pins, and the travel gear box 2 and the side frame 12 are both made of aluminum sheet material. Pin connection by means of locating pins can ensure that the relative position between the travel gear box and the side frame is accurate. Through precise hole matching, the locating pins can firmly connect the two together, avoiding structural instability caused by looseness or displacement. This stable connection method is particularly important for working environments that withstand dynamic loads and vibrations, and can effectively improve the overall strength and stability of the frame. When the frame is subjected to external load, the locating pin can effectively disperse the load to the contact surface between the travel gear box and the side frame, avoiding the occurrence of stress concentration. This way of dispersing the load not only enhances the load-bearing capacity of the frame, but also reduces the risk of structural damage caused by excessive local stress. At the same time, the locating pin itself also has a certain load-bearing capacity, which can further enhance the overall strength of the frame. During long-term use, the frame may be slightly deformed by various external forces. The connection method of the locating pin can effectively resist this deformation and maintain the accuracy and stability of the frame. Due to the close fit between the locating pin and the hole position, even if the frame is subjected to a certain external force, the relative position between the components can be kept unchanged by the constraint of the locating pin, thereby ensuring the overall strength and accuracy of the frame. The locating pin also simplifies the assembly process of the frame. Through the pre-processed holes and locating pins, the connection between the travel gear box and the side frame can be quickly realized without complicated adjustment and calibration processes. This simplified assembly method not only improves production efficiency, but also reduces human errors and deviations in the assembly process, 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 sealing plate 21 is provided on the top of the traveling gearbox 2, and the upper sealing 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 sealing 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 sealing plate can effectively disperse the pressure and improve the bearing capacity of the gearbox. The upper sealing plate can also play a certain sound insulation effect, 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, a side frame hollow through hole is provided on the side frame 12; a cross frame hollow through hole is provided on the cross frame 11; at the same time, a travel gear box hollow through hole corresponding to the side frame hollow through hole is provided on the travel gear box 2, and a lifting gear box hollow through hole corresponding to the cross frame hollow through hole is provided on the lifting gear box 1; the most direct advantage of the design of the hollow through hole is that it can reduce the weight of the frame. By removing unnecessary materials, the overall mass of the frame can be significantly reduced, which is crucial for improving the energy efficiency of the vehicle, reducing energy consumption and improving driving performance. At the same time, in application scenarios that require frequent start and stop, lightweight design can reduce energy loss and improve overall operating efficiency. In the present invention, although hollowing is performed, the position, shape and size of the hollowing will be calculated during the design to ensure that the key parts of the frame still maintain sufficient strength and rigidity. The design of the hollow through hole is usually avoided in the area that bears the main load or stress, but in the non-critical area or the area with less stress, so as to achieve weight reduction without sacrificing strength. The hollow through-hole design helps optimize the structural layout of the frame and make the material distribution more reasonable. By removing excess material, the strength of key parts can be strengthened more concentratedly, improving the overall performance of the frame. Furthermore, the hollow through-hole design can also increase the surface area and air circulation channels of the frame, which helps to improve the heat dissipation performance. During the operation of the vehicle, components such as the gearbox will generate heat. The hollow design can better promote air circulation, help dissipate heat, reduce the operating temperature of components, and extend the 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 protection scope of the present invention.
