Description

Technical Field

[0001] The utility model relates to the technical field of aerial platforms, in particular to a wheel structure of an aerial platform. Background Art

[0002] Aerial climbing vehicle, also known as aerial work vehicle or aerial work vehicle, is a special vehicle used for aerial work or rescue. It is mainly used for aerial work and emergency repair in power, communication, street lights, traffic police, highways, industrial and mining enterprises, etc. Aerial climbing vehicle has the characteristics of smooth lifting, simple operation, large load capacity, large operating range, safety and reliability. The wheels of aerial climbing vehicle are an important part of aerial climbing vehicle. The material and size of the wheels vary depending on the model and purpose of aerial climbing vehicle. Generally speaking, aerial climbing vehicle is made of high-quality steel and equipped with high-quality casters to ensure that it can be moved flexibly.

[0003] The wheel structure of a common aerial platform is usually composed of a tire, a rim, a spoke, an axle, a bearing, and a brake system. The wheel is placed on the axle to ensure that the wheel is aligned with the axle, and the wheel and the axle are fixed together with bolts or nuts. The wheel is usually installed around the bottom of the aerial platform, and the aerial platform moves through the wheels and brakes through the brake system. This is a common wheel structure and usage of the aerial platform. The wheel structure of the traditional aerial platform will reduce the support force of the wheel structure after long-term use, and it is easy to be damaged. The wheel structure of some aerial platforms is improved by adding a reinforcement plate inside, thereby improving the overall structural support force of the wheel. However, this method is limited in improving the overall structural support force of the wheel because only a single set of reinforcement plates is used, and the overall structural support force of the wheel cannot be greatly improved, resulting in damage to the wheel of the aerial platform after long-term use. For this reason, a wheel structure of a aerial platform is proposed. Utility Model Content
