Super-tonnage three-bridge rigid mining dump truck

Abstract

The invention discloses a super-tonnage three-axle rigid mining dump truck. A container damping system and a cab are arranged above a rigid frame; one end of a lifting system is connected with the rigid frame, and the other end is connected with the container damping system; a steering system is arranged on the rigid frame; a suspension system and a moving shaft arrangement system are arranged below the rigid frame; a transmission system is arranged below the cab; the transmission system is connected with the transmission shaft arrangement system; the intelligent lubricating system is arranged in the cab; according to the invention, the goods tank load can be uniformly distributed on the cross beams and the longitudinal beams of the frame, so that breakage caused by concentration of the goods tank load on the longitudinal beams of the frame is avoided; the goods box is prevented from deflecting leftwards and rightwards in the vehicle steering process, and safety accidents such as rollover are avoided; the performance is excellent, the maintenance is convenient, the impact of pavement feedback on the frame can be reduced, and the fatigue life of a frame base body is prolonged; different mine pavements are adapted, and the reliability of a transmission system is improved; the system is more intelligent; the failure rate of the whole vehicle can be reduced.

Description

technical field [0001] The invention relates to a super-large tonnage three-axle rigid mining dump truck, which belongs to the technical field of dump trucks. Background technique [0002] Mining dump truck is the key equipment in open-pit mining and large-scale earthwork construction, and it is a professional equipment for ore or earthwork transportation. Shuangqiao mining carts have always been the main equipment for mine transportation, with a tonnage covering 32 to 363 tons, especially the 91-ton mining carts can be called the "golden ton class" of mining carts, and are widely used in civil engineering and mines. [0003] However, with the increasing scarcity of resources, a large number of low-grade mines have also begun to be mined. These mines have a short mining cycle and a long transportation distance, and the double-bridge mine trucks can no longer meet the market demand; Breaking away from the technical route of heavy trucks, it has been difficult to break throug...

AI Technical Summary

Problems solved by technology

[0003] However, with the increasing scarcity of resources, a large number of low-grade mines have also begun to be mined. These mines have a short mining cycle and a long transportation distance, and the double-bridge mine trucks can no longer meet the market demand; Breaking away from the technical route of heavy trucks, it has been difficult to break through the technical bottleneck of 75 tons of load

Traditional mining dump trucks do not have a unique container damping system. The container limit does not use soft limit and no shock absorber is designed. It is easy to cause the load of the container to concentrate on the frame longitudinal beam and break; During the process, the cargo box is prone to yaw left and right, causing safety accidents such as rollover; the front suspension in the suspension system is not equipped with an independent suspension oil cylinder, which is not easy to maintain. The impact of road feedback on the frame is large, and the life of the frame base is short. ; Low degree of intelligence; high failure rate
