AI Technical Summary
When the existing aerial work vehicle turntable meets the demand for large-scale and large-height blue brands, it is difficult to take into account both rigidity, lightweight and economicality. There is a lack of balance between the three. The pear-shaped cross-section cost is high, the circular cross-section is poor, and the veneer form is Inadequate rigidity.
The multi-small box side box structure consisting of inner vertical plate, outer bent plate and partition plate is adopted to improve rigidity by strengthening the plate connection and hinge point components (including bent plate, patch plate and shaft sleeve), and to improve rigidity through outer bend The "convex" glyph structure and boom design enhance the plane and side rigidity.
It realizes the high rigidity, low self-weight and low production costs of the turntable of the aerial work vehicle. It is suitable for construction machinery with rotation, such as aerial work vehicle, crane, fire truck, etc., improving the overall performance and economy.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of aerial work vehicles, in particular to a turntable for aerial work vehicles. Background Art
[0002] At present, the market demand for aerial work vehicles tends to be large-scale and high-height blue plates. Due to the weight limit of blue plates, higher rigidity and lightweight requirements will be put forward for the turntable, while also ensuring the economic efficiency of the product. There are currently three typical structural forms in China: the first is a pear-shaped cross-section box form, the second is a circular cross-section box form, and the third is a single-sided "concave" cross-section single plate form. These three structural forms have failed to balance the three. The cost of pear-shaped and circular cross-sections is relatively high, and the rigidity of the single plate form is poor.
[0003] Therefore, it is necessary to develop a new type of turntable for aerial work vehicles in a targeted manner to improve rigidity and reduce production costs. Utility Model Content
[0004] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides a turntable for an aerial work vehicle, which has the beneficial effects of good rigidity, light weight and low production cost.
[0005] Technical solution: The utility model is a turntable for aerial work vehicles, characterized in that it includes a side box body with multiple small boxes composed of an inner vertical plate, an outer bent plate and a partition plate, two side boxes are symmetrically arranged, the two side boxes are both connected to the bottom plate, the two side boxes are connected by a reinforcing plate, and the hinge assembly between the two side boxes includes a bent plate, a pasting plate and a shaft sleeve.
[0006] Wherein, the outer curved plate is a "convex" shaped structure.
[0007] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the turntable of the utility model is practical for engineering machinery with rotation, such as aerial work vehicles, cranes, fire trucks, cleaning vehicles, etc., and has the beneficial effects of good rigidity, light weight, and low production cost.

[0013] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0014] The utility model of the aerial work vehicle turntable comprises a side box body with a variety of small boxes composed of an inner side vertical plate 1, an outer side curved plate 7 and a partition plate 8, two side boxes are symmetrically arranged, both of the two side boxes are connected to a bottom plate 6, the two side boxes are connected by a reinforcing plate 5, and the hinge assembly between the two side boxes comprises a curved plate 2, a pasting plate 3 and a shaft sleeve 4. The outer side curved plate 7 is a "convex"-shaped structure.
[0015] like Figure 1-4 The utility model provides a turntable for aerial work vehicles: the side box body with various small boxes is composed of an outer curved plate 7, an inner vertical plate 1 and a partition 8. The two side boxes are symmetrical about the middle plane and connected to the bottom plate 6 as a whole. The reinforcing plate 5 connects the boxes on both sides to strengthen them. The hinge assembly is composed of a shaft sleeve 4, a plate 3 and a curved plate 2. The outer curved plate 7 is a "convex" shape, and uses an arm body pressing mold. Compared with the conventional form, it has less bending. When the boom rotates, the front and rear planes can be fully utilized to provide higher rigidity. When the boom changes its amplitude, the pressed side plate can be fully utilized to provide higher rigidity, and the convex form is more compatible with the circular rotating mechanism. The inner vertical plate 1 also provides rigidity when the boom changes its amplitude. The partition 8 also provides rigidity when the boom rotates. The side box body with various small boxes, which is composed of the outer curved plate 7, the inner vertical plate 1 and the partition 8, can well resist deformation caused by torsion. The two side boxes are symmetrical about the middle plane and connected to the bottom plate 6. The reinforcing plate 5 connects the two side boxes to each other and strengthens them, further improving the integrity of the turntable and providing better rigidity. After the rigidity is sufficient, the turntable is further lightweight. The hinge assembly consists of a shaft sleeve 4, a plate 3 and a bent plate 2. The hinge position is partially reinforced to improve rigidity.
