A double-girder cantilever crane with explosion-proof moving wheels

Abstract

The invention discloses a double-girder cantilever crane with explosion-proof moving wheels, and relates to the technical field of explosion-proof tires for mechanical equipment. It includes a car body and a power assembly, a crane is installed on the car body, the power assembly is fixedly installed at the bottom of the car body, an explosion-proof mobile wheel assembly is installed on the car body, and the explosion-proof mobile wheel assembly includes a vacuum tire And an explosion-proof hub assembly, the explosion-proof hub assembly includes a hub side wall and a hub ring, and the tubeless tire is socketed and installed on the hub ring, a high-pressure ring is fixedly installed on the outer wall of the hub side wall, and the high-voltage ring is connected to the hub side wall A high-pressure chamber is arranged between them. By setting the explosion-proof hub assembly, the double-girder cantilever crane can run on uneven roads, and the double-girder cantilever crane can maintain a stable and balanced air pressure in the vacuum tire during the driving process to avoid excessive or low tire pressure. The phenomenon of preventing tubeless tires from blowing out is safer and more stable.

Description

technical field [0001] The invention relates to the technical field of explosion-proof tires for mechanical equipment, in particular to a double-girder cantilever crane with explosion-proof moving wheels. Background technique [0002] The main features of the tire crane are: the driving cab and the lifting control room are combined into one, and it is evolved from a crawler crane (crawler crane). The shortcomings of crawler cranes (crawler cranes) that crawler shoes cause damage to the road surface are eliminated, and they belong to material handling machinery. In order to move more conveniently, in the prior art, a vehicle-mounted cantilever crane is used for lifting operations, which facilitates the movement of the crane, thereby enabling effective lifting operations in multiple areas. [0003] In the existing lifting operation, the lifting weight is often relatively large, which has a great test on the tires at the bottom of the crane. Cranes are generally used in constr...

AI Technical Summary

Problems solved by technology

[0003] In the existing lifting operation, the lifting weight is often relatively large, which has a great test on the tires at the bottom of the crane. Cranes are generally used in construction sites. At present, the road conditions on the construction site are relatively poor, and there are often potholes On the road surface, and the mass of the crane is relatively large, when the crane tires are in contact with the potholes, there will be a large deformation, which will cause the inner tire pressure to be too high, resulting in a tire blowout, and when driving on the potholes , The tire pressure of the crane cannot be adjusted in time, so that the tire pressure inside the tire cannot reach a balanced state, and the phenomenon of tire blowout is prone to occur.
