Description

Technical Field

[0001] This utility model relates to the field of aerial work platform technology, specifically a straight boom aerial work platform chassis. Background Technology

[0002] The existing articulated boom aerial work platform chassis has a complex structure, low assembly efficiency, and low after-sales maintenance efficiency. This is because the chassis structure makes installation with the front and rear axles inconvenient, and maintenance is equally inconvenient. During chassis assembly, the motor needs to be fixed to the adapter first, then the front axle welded to the chassis is fixed with pins, and then connected to the tires. In addition, each motor wire needs to be connected to the front and rear drives, which affects the assembly efficiency.

[0003] Therefore, in order to facilitate installation and subsequent maintenance, the chassis structure was simplified by integrating the walking power system, which greatly reduced assembly and maintenance time. The walking power was integrated into one system, with a walking motor connected to the gearbox and then connected to the front and rear axles via a drive shaft, which facilitated assembly and after-sales maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a straight boom aerial work platform chassis, which solves the problems of complex chassis design, low assembly efficiency, and low efficiency in subsequent maintenance and repair.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a straight boom aerial work platform chassis, including a chassis, and an integrated power transmission structure installed inside the chassis; the power transmission structure includes a gearbox, a rear axle, a front axle, and a drive shaft; the rear axle is installed on the left side of the chassis, the front axle is installed on the right side of the chassis, and one side of the rear axle is connected to the gearbox installed on the chassis and connected to the front axle through the drive shaft.

[0006] Furthermore, through the above technical solution, the outer end of the front axle is movably connected to a steering arm, and a hydraulic cylinder is installed on the steering arm, with the telescopic end of the hydraulic cylinder connected to the surface of the front axle.

[0007] Furthermore, a front wheel hub is mounted on the outer surface of the steering arm, and a rear wheel hub is mounted on the movable end of the rear axle.

[0008] Compared with the prior art, this utility model provides a straight boom aerial work platform chassis, which has the following advantages: 1. This chassis, by changing the layout of the power system, simplifies its structure and greatly improves efficiency in subsequent assembly and maintenance. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0012] Please see Figure 1-3 The present invention provides the following technical solution: a straight boom aerial work platform chassis, including a chassis 1, in which an integrated power transmission structure is installed; the power transmission structure includes a reduction gearbox 3, a rear axle 4, a front axle 5, and a drive shaft 6; the rear axle 4 is installed on the left side of the chassis 1, and the front axle 5 is installed on the right side of the chassis 1. One side of the rear axle 4 is connected to the reduction gearbox 3 installed on the chassis 1, and is connected to the front axle 5 through the drive shaft 6. The reduction gearbox 3 mainly transmits power to the front axle 5 and the rear axle 4 respectively, while the front axle 5 is connected and driven through the drive shaft 6.

[0013] In this implementation plan, the specific working principle is as follows: via the appendix Figure 1-3 As can be seen, this chassis 1 integrates the power transmission structure (walking power system), thereby simplifying the structure of chassis 1 and making the structural layout clear. This can significantly improve the efficiency of assembly and subsequent maintenance.

[0014] For details on how the front axle 5 achieves steering, please refer to [link / reference]. Figure 2 As can be seen, a steering arm 7 is movably connected to the outer end of the front axle 5, and a hydraulic cylinder 8 is installed on the steering arm 7. The extension and retraction end of the hydraulic cylinder 8 is connected to the surface of the front axle 5. The steering arm 7 is rotated by the hydraulic cylinder 8, thereby realizing steering.

[0015] As can be seen from 1-3, the outer surface of the steering arm 7 is fitted with a front wheel hub 9, and the movable end of the rear axle 4 is fitted with a rear wheel hub 2.

[0016] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
