[0004] In this regard, the conventional solution is to install protective structures on the vulnerable parts of the chassis, such as battery guards, engine guards and other structures. Although these structures can block external debris to a certain extent, the added guards also surround the peripheral space of the corresponding components, occupying the operable space during maintenance and replacement. The operator's movements are interfered with by the chassis structure, resulting in maintenance difficulties. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0026] Embodiment 1

[0027] like Figure 1 As shown, a work platform chassis includes a chassis body, on which functional components are arranged. The functional components refer to various power and control hardware structures installed on the engineering machinery chassis, such as the present embodiment. Figure 1 The battery pack 6 and the hydraulic system 11 shown in FIG. 1 are specifically:

[0028] like Figure 1-5 As shown, the chassis body includes a chassis bottom plate 1, and side support assemblies are provided on both sides of the chassis bottom plate 1. As shown in the figure, the side support assembly includes a chassis side plate 12, and the bottom edge of the chassis side plate 12 is fixedly connected to the two side edges of the chassis bottom plate 1, and the chassis side plate 12 is perpendicular to the chassis bottom plate 1, and reinforcing structures such as reinforcing ribs and reinforcing columns are provided between the two. In this way, the chassis bottom plate 1 and the side support assembly together enclose a groove-shaped space, and along the horizontal extension direction of the groove-shaped space, one end of the chassis body is an open end, and the end is set as the front end, and the rear end of the chassis body is a closed end, that is, a blocking plate is installed at the rear end edges of the chassis bottom plate and the two chassis side plates. At the same time, a top support assembly such as a cross beam and a top cover plate can be further installed between the tops of the two chassis side plates 12, so as to strengthen the structural strength of the chassis body and form a supporting surface for installing the actuator on the platform chassis.

[0029] A tray assembly is slidably installed in the above-mentioned slot space, such as Figure 1As shown, the tray assembly can be pulled out through the open end of the chassis body, so that the chassis forms a drawer-type structure. The tray assembly includes a tray bottom plate 2 and a tray vertical plate 13. The bottom edge of the tray vertical plate 13 is fixedly connected to the side edge of the tray bottom plate 2. A reinforcing rib plate is also provided between the tray bottom plate 2 and the tray vertical plate 13. The reinforcing rib plate is located at the two side edges of the tray bottom plate 2 and the tray vertical plate 13. The tray bottom plate 2 can slide into the groove-shaped space. When the tray bottom plate 2 is located in the groove-shaped space, the tray vertical plate 13 covers the open end of the chassis body. A plurality of supporting wheels 9 are also provided on the inner side of the two side support assemblies (i.e., the side facing the groove-shaped space, the opposite sides of the two) and the supporting wheels 9 are arranged along the sliding direction of the tray assembly. Guide rails 10 are also provided on both sides of the tray assembly. The supporting wheels 9 support the guide rails 10 so that the tray assembly can be pulled out smoothly. At the same time, a plurality of locking mechanisms are also provided between the tray assembly and the chassis body for limiting different pull-out positions of the tray bottom plate.

[0030] The tray bottom plate is divided into multiple installation areas along the sliding direction. Functional components can be arranged in different areas according to the maintenance frequency. Components with high maintenance frequency are arranged at the front, and components with low maintenance frequency are arranged at the rear. That is, components that need frequent maintenance only need to be slightly pulled out of the tray assembly during maintenance, saving operation time. For example, in this embodiment, the hydraulic system 11 is arranged at the front of the tray bottom plate, and the battery pack 6 is arranged at the rear of the tray bottom plate. Based on this, an intermediate locking mechanism is arranged between different installation areas, such as Figure 2-4 As shown, the intermediate locking mechanism includes a first baffle plate 3 and a first hook plate 4. A square hole is provided on the chassis bottom plate 1 near the open end of the chassis body. A first connecting plate 3-1 is fixedly installed at the bottom of the first baffle plate 3. The first connecting plate 3-1 is perpendicular to the first baffle plate 3. The first connecting plate 3-1 is detachably installed on the bottom surface of the chassis bottom plate 1 by connecting parts such as bolts. The first baffle plate 3 passes through the square hole and protrudes from the upper surface of the chassis bottom plate 1. The first hook plate 4 is fixedly installed at the boundary position between adjacent installation areas on the lower surface of the tray bottom plate 2 and protrudes downward relative to the lower surface of the tray bottom plate 2. Along the sliding direction of the tray assembly, the first hook plate 4 coincides with the first baffle plate 3. That is, when a certain installation area on the tray assembly is completely pulled out, the first baffle plate 3 blocks the first hook plate 4, thereby preventing the tray assembly from being further pulled out, and the staff can inspect the components in the current installation area; when the tray assembly needs to be further pulled out, the first connecting plate 3-1 can be removed from the chassis bottom plate, and the tray assembly can be further pulled out.

[0031] When the tray assembly is almost fully pulled out, an anti-slip locking mechanism is provided between the chassis body and the tray assembly, and the anti-slip locking mechanism includes a second baffle plate 5 and a second hook plate 14. The structure of the second baffle plate 5 is the same as that of the first baffle plate, and the structure of the second hook plate 14 is the same as that of the first hook plate. The difference from the intermediate locking mechanism is that the second hook plate 14 is installed at the rear edge of the floor of the tray bottom plate, and along the sliding direction of the tray assembly, the second baffle plate 5 coincides with the second hook plate. When the tray assembly is almost fully pulled out, the second baffle plate 5 blocks the second hook plate 14, and the tray assembly can be completely removed from the chassis body by removing the second baffle plate 5.

[0032] The locking mechanism also includes a switch locking mechanism, which locks the pallet bottom plate and its upper components inside the chassis body in a non-maintenance state. The switch locking mechanism includes a movable hook 8 and a fixed hook 7. One of the movable hook 8 and the fixed hook 7 is installed at the open end of the chassis body, and the other is installed at the front end of the pallet assembly. In this embodiment, the fixed hook 7 is fixedly installed on the inner side of the side support assembly, and the bayonet of the fixed hook 7 faces upward. The movable hook is installed on the reinforcing rib plate between the pallet bottom plate and the pallet vertical plate on the pallet assembly. The movable hook includes a hinge part 8-1, a hook part 8-2 and an operating part 8-3, the hinge part 8-1 is hingedly installed on the side of the reinforcing rib plate, the hook part 8-2 and the operating part 8-3 extend to the front and rear sides of the hinge part respectively, the hook part has a bevel angle at the front end downward, and the extension length of the hook part 8-2 is longer than the extension length of the operating part, so that in a natural state, the hook part 8-2 droops, and can be engaged with the fixed hook 7 by gravity. The operating part is provided with a pull rod, and the pull rod can be pulled downward to lift the hook part and release the lock between it and the fixed hook 7.

[0034] Based on the working platform chassis provided in Example 1, this embodiment further provides an aerial work equipment, including the working platform chassis described in Example 1, with walking mechanisms provided on both sides of the chassis body, and a lifting mechanism installed on the supporting surface. In this embodiment, the walking mechanism is a crawler structure, and the lifting mechanism is a scissors-type structure (which is an existing structure and will not be described again here), and a working platform is provided at the upper end of the lifting mechanism.

[0035] Furthermore, in the present embodiment, the fence of the working platform is a foldable structure, which can reduce the overall height space of the equipment in the storage state and can pass through a lower space.

[0036] It can be seen from the above embodiments that the advantages of the utility model are that the chassis of this scheme adopts a drawer-type structure, and the internal tray assembly can be pulled out to inspect and repair the equipment thereon. In the stored state, the chassis body forms a closed space, which realizes comprehensive protection for the equipment inside and isolates external debris such as mud, sand and gravel, ensuring the cleanliness and service life of the equipment; during maintenance, the tray assembly is pulled out, and there is no other structure blocking the equipment around, so the maintenance operation space is large and the maintenance is more convenient; through the structural design of the support wheel, locking mechanism and other structural designs of this scheme, the tray assembly can be pulled out smoothly, and the equipment layout can be optimized. The locking mechanism is set at an appropriate position, and the pulling degree is set to reduce the labor intensity of maintenance personnel and improve maintenance efficiency; further, the aerial work platform provided by the utility model has a long service life, is easy to inspect and maintain, and the work platform can be stored to reduce the overall height and improve passability.
