The chassis has an internal cavity, and movable structures are installed on the front and rear sides of the chassis. A pull-out installation structure is installed in the cavity, comprising a pull-out plate and guide rails. The guide rails are installed on the front and rear sides of the pull-out plate, and there is a gap between adjacent sets of guide rails. The gap area is movably connected to the movable structure, and electrical components are installed on the upper surface of the pull-out plate.

[0006] Furthermore, the movable structure includes a connecting shaft and a bearing; the connecting shaft is symmetrically installed on the inner side of the cavity, and a bearing is installed on the surface of the connecting shaft, which is movably connected to the guide rail.

[0007] Furthermore, the upper surface of the pull-out plate is also provided with a surrounding plate, wherein the electrical components are placed on the upper surface of the electrical components and are wrapped by the surrounding plate.

[0008] As a preferred technical solution, a connecting rod is also installed on the upper end face of the pull-out plate, a fixing plate is provided on the upper end face of the connecting rod, bolts are installed on the surface of the connecting rod, and the lower end face of the fixing plate is in contact with the upper end face of the electrical component.

[0009] Furthermore, a cover plate is also installed on the upper surface of the chassis.

[0010] As a preferred technical solution, hydraulic support bodies are symmetrically installed on both the front and rear sides of the chassis.

[0011] Furthermore, a ladder is installed on the right side of the chassis.

[0012] Compared with the prior art, this utility model provides a tracked aerial work platform chassis, which has the following beneficial effects:

[0013] 1. This chassis features an internal movable structure that allows for the sliding panel to be moved out of the chassis. Electrical components are installed on the sliding panel, which eliminates the need to remove the cover for maintenance and inspection. Furthermore, the large operating space after pulling out the panel facilitates maintenance. In addition, if the boom cannot be raised, there is no need to use a crane to forcibly lift the boom to open and inspect the battery compartment, making it more convenient.

[0019] 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

[0020] Please see Figure 1-3The present invention provides the following technical solution: a tracked aerial work platform chassis, including a chassis 1, a hydraulic support body 2, and a ladder 3. A pull-out installation structure is installed in the cavity. The pull-out installation structure includes a pull-out plate 5 and a guide rail 6. The guide rail 6 is installed on the front and rear sides of the pull-out plate 5, and there is a gap between two adjacent sets of guide rails 6. The gap area is movably connected to the movable structure. An electrical component 8 is installed on the upper surface of the pull-out plate 5.

[0021] In this implementation plan, the specific working principle is as follows: all electrical components are installed on the pull-out plate 5 on the chassis 1, and then the pull-out plate 5 is pushed to move into the interior of the chassis 1. This operation is not only more convenient when installing electrical components, but also when repairing electrical components, simply pull out the pull-out plate 5. This not only increases the operating space, but also facilitates maintenance personnel. Furthermore, if the boom cannot be raised, there is no need to use a crane to forcibly lift the boom to open and inspect the battery compartment, which is more convenient.

[0022] Based on the above, in order to facilitate the smooth extension of the pull-out panel 5, please refer to the following for details. Figure 2 As can be seen, the movable structure includes a connecting shaft 12 and a bearing 4; the connecting shaft 12 is symmetrically installed on the inner side of the cavity, and the bearing 4 is installed on the surface of the connecting shaft 12, and the bearing 4 is movably connected to the guide rail 6.

[0023] To protect electrical components 8 and prevent swaying during chassis 1 movement, please refer to [the relevant documentation]. Figure 1 As can be seen, the upper surface of the pull-out plate 5 is also provided with a surrounding plate 7, in which the electrical component 8 is placed on the upper surface of the electrical component 8 and is wrapped by the surrounding plate 7.

[0024] For further details on securing electrical component 8, please refer to [link / reference needed]. Figure 3 and Figure 4 As can be seen, a connecting rod 9 is also installed on the upper end face of the pull-out plate 5. A fixing plate 10 is provided on the upper end face of the connecting rod 9. Bolts are installed on the surface of the connecting rod 9. The lower end face of the fixing plate 10 is in contact with the upper end face of the electrical component 8.

[0025] To facilitate checking whether there is a problem with electrical component 8, please refer to the following: Figure 3 As can be seen, a cover plate 11 is also installed on the upper surface of the chassis 1. It should be noted that the cover plate 11 can only be viewed after the boom is raised. If a problem occurs, the cover plate 11 can be removed to check for damage, or the bracket can be pulled out by pulling out the pull plate 5 for inspection. Both methods are acceptable.

[0026] To improve the stability of chassis 1, please refer to the following: Figure 1 As can be seen, hydraulic support bodies 2 are symmetrically installed on the front and rear sides of the chassis 1. When the boom begins to extend, the chassis 1 is supported by the hydraulic support bodies 2, which provides better visibility of the support of the chassis 1.

[0027] For details on facilitating climbing, please refer to [link / reference]. Figure 3 As can be seen, a ladder 3 is installed on the right side of chassis 1.

[0028] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
