Super-heavy mining dump truck

Abstract

The invention discloses a super-heavy mining dump truck, which belongs to the field of mining dump trucks. The super-heavy mining dump truck comprises a chassis and a truck body, wherein the chassis comprises a transmission system, a running system, a steering system and a braking system; the truck body comprises a cab and a container. The mining dump truck is characterized in that: a frame in the running system is a welded box type variable section frame without a secondary frame; the transmission system comprises a 6*4 mechanical transmission driving device; a middle axle and a rear axle in the running system form a dual driving axle; a rear suspension consisting of the middle axle and the rear axle in the running system is a hydropneumatic balance suspension with an energy storage adjusting mechanism; front wheels are single tires with the tire nominal section width, rim nominal diameter and tread ply of between 33.00-51-58 and 27.00-49-48; and middle wheels and rear wheels are double tires with the tire nominal section width, rim nominal diameter and tread ply of between 24.00-49-48 and 21.00-35-36. The invention is mainly used for manufacturing a domestic super-heavy mining dump truck which is suitable for domestic working conditions, has high efficiency and is low in using cost.

Description

technical field [0001] The invention relates to the field of super-heavy mining dump trucks, in particular to a material transport vehicle used in the fields of mines, buildings, water conservancy and hydropower construction, and the like. Background technique [0002] In recent years, in some coal mining areas at home and abroad, surface mining has been widely used instead of hole mining. Open-pit mining technology has a series of characteristics such as low mining cost, high collection efficiency, and a relatively safe mining environment. It has incomparable advantages over cave mining when the coal seam is not too deep. Among the proven coal reserves in my country, the coal seams in Inner Mongolia, Qinghai, Xinjiang and other places are relatively shallow and suitable for open-pit mining. Due to the lack of large-scale mining vehicles in these mining areas, the annual output is far from meeting the increasing coal demand in China, and this state of shortage is getting wo...

Problems solved by technology

When foreign technologies enter the domestic market, they have to face two main problems: ①The price of imported mining vehicles is too high, which makes many customers stop

②The annual maintenance cost of hundreds of thousands or even hundreds of thousands also causes headaches for many customers

The casting structure is prone to casting defects such as blisters and carbon deposits, especially for structural parts such as beams with complex structures, the quality of castings is not easy to control
