Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a tread plate and a construction machinery. Background Art

[0002] At present, tread plates are arranged on both sides of the chassis of a wheel crane to provide a platform for operators to walk and place items. Each side platform is connected by multiple tread plates. The structure of a single tread plate is mainly welded by a metal panel, metal reinforcing ribs and decorative strips, and the reinforcing ribs are used to improve the stiffness of the tread plate and for connection and fixation.

[0003] As Figure 1 shown, the metal tread plate structure mainly includes a metal thin corrugated panel 31, reinforcing ribs 32 and decorative strips 33. The reinforcing ribs 32 and the decorative strips 33 are respectively fixedly connected to the metal thin corrugated panel 31 by welding or riveting. The tread plate corrugated panel is usually made of an aluminum alloy or iron thin plate with a thickness of 3 - 4 mm. At the same time, angle-shaped reinforcing ribs 32 or channel-shaped reinforcing ribs 32 are welded or riveted inside the corrugated panel to improve the overall stiffness of the tread plate. The decorative strips 33 are arranged on the outer side of the tread plate. On the one hand, they can play a certain supporting role for the outer edge of the tread plate, and on the other hand, they serve for appearance decoration. To improve the overall aesthetic effect and anti-corrosion effect of the tread plate, the whole tread plate needs to be surface-treated to prevent rust. However, the above metal tread plate structure has the following disadvantages: the tread plate is made of metal material, which is heavy and inconvenient to assemble; the decorative strips 33 are fixedly connected to the outside of the vehicle by welding and are easily damaged. When the decorative strips 33 are damaged, the whole tread plate needs to be replaced, and the replacement cost is relatively high; the panel of the tread plate is made of metal and needs surface treatment such as topcoating or powder spraying. When the coating on the surface of the tread plate panel is damaged, the surface of the tread plate panel is prone to rust and is not beautiful. Summary of the Utility Model
