Description

Technical Field

[0001] This utility model relates to a lightweight chassis structure for engineering vehicles, belonging to the field of engineering machinery technology. Background Technology

[0002] The chassis of an engineering welding vehicle is the equipment that bears the weight of the entire vehicle and serves to connect the platform and tracks. Currently, almost all engineering welding vehicles use box-type chassis. While box-type chassis offer reliable strength and a robust structure, they also suffer from drawbacks such as heavy weight, a large amount of welding work, high overall structural component costs, and inconvenient piping layout, leading to a higher risk of damage to exposed pipes and reducing the vehicle's lifespan. Therefore, there is an urgent need for a lightweight chassis structure for engineering vehicles that is simple in structure, lightweight, low in cost, and provides good protection for piping. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a lightweight chassis structure for engineering vehicles that is simple in structure, light in weight, low in cost, and provides good protection for pipelines.

[0004] The purpose of this utility model is achieved as follows:

[0005] A lightweight chassis structure for an engineering vehicle includes a platform installed between the left and right tracks of the engineering vehicle to support the vehicle. The platform comprises two parallel frame beams arranged between the two tracks. A first connecting frame, a baffle, and a second connecting frame are sequentially installed on each frame beam. The first connecting frame, baffle, and second connecting frame on the two frame beams are symmetrically arranged front and rear. The first connecting frame and the second connecting frame are connected to the platform.

[0006] Furthermore, side sealing plates are installed on the inner edges of the two frame beams to protect the pipeline wiring from being exposed.

[0007] Furthermore, a frame reinforcing rib is installed between the first connecting frame, the second connecting frame, and the platform.

[0008] Furthermore, connecting reinforcing ribs are installed between the first connecting frame, the second connecting frame and the vehicle frame beam.

[0009] Furthermore, a rectangular cable pass hole is provided on the frame beam.

[0010] Furthermore, a bottom sealing plate is installed at the bottom of the platform located between the two vehicle frame beams.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model's lightweight chassis structure for engineering vehicles simplifies the structure by setting up two independent frame beam structures, reducing the number of connecting structural components between the two frame beams, thus reducing the overall weight of the chassis, the amount of welding work, and the cost. The side sealing plates protect the pipelines from being exposed, providing good protection. The modular and standardized design of the overall structure improves the efficiency of disassembly and installation. Attached Figure Description

[0017] See Figures 1-2 This utility model relates to a lightweight chassis structure for an engineering vehicle, which is a platform 10 welded and installed between the left and right tracks 1 of the engineering vehicle to support the engineering vehicle. It includes two frame beams 2 arranged parallel between the two tracks 1. Side sealing plates 6 are installed on the inner side of the two frame beams 2 to protect the pipelines and improve the protection performance. A rectangular cable hole 9 is opened on one of the frame beams 2 to facilitate the laying of pipelines and cables.

[0018] A first connecting frame 3, a baffle 4, and a second connecting frame 5 are sequentially installed on each frame beam 2; the first connecting frame 3, the baffle 4, and the second connecting frame 5 on the two frame beams 2 are arranged symmetrically front and back; a connecting reinforcing rib 8 is installed between the first connecting frame 3, the second connecting frame 5 and the frame beam 2 to improve the structural strength of the first connecting frame 3, the second connecting frame 5 and the frame beam 2;

[0019] The first connecting frame 3 and the second connecting frame 5 are connected to the platform 10. A frame reinforcing rib 7 is installed between the first connecting frame 3, the second connecting frame 5 and the platform 10. A bottom sealing plate 11 is installed at the bottom of the platform 10 between the two frame beams 2 to protect the pipelines at the bottom of the platform 10 from being exposed. When the chassis and the platform 10 are welded together, only the first connecting frame 3 and the second connecting frame 5 of the two frame beams 2 need to be welded to the platform 10 separately, which reduces the amount of welding work and improves work efficiency. At the same time, since the two frame beams 2 are independent of each other, the assembly space is increased, which facilitates the assembly and welding operation.

[0020] Compared with the traditional box-type chassis, the two frame beams 2 in this embodiment are independent of each other, and each frame beam 2 is individually connected to the platform 10. This reduces the number of connecting structural components between the two frame beams 2, simplifies the structure, reduces weight, reduces welding processes, and lowers costs.

[0021] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
