Problems solved by technology

The sub-frame of the powertrain needs to be installed on the inner side of the frame longitudinal beam through several support seats. The rear support seat of the existing sub-frame is usually directly welded to the inner web of the frame longitudinal beam. Considering the welding process of the frame Welding deformation will occur, so that the welding size of the rear support cannot be accurately guaranteed

Abstract

The invention discloses an adjustable sub-frame support device of a mining dump truck and a mining dump truck, comprising a left power rear support assembly and a right power rear support assembly; the left power rear support assembly and the right power rear support assembly The structure is the same, and the two are symmetrically arranged between the frame and the sub-frame of the powertrain. The left power rear support assembly includes a power rear support straight beam, a power rear support beam, a semi-arc rear seat, a semi-arc seat cover and standard parts. The power rear support straight beam is welded on the lower cover plate of the longitudinal beam of the frame; the power rear support beam is inserted into the rectangular hole of the power rear support straight beam, and is welded with the circumference of the surface of the power rear support beam; the semi-arc rear seat is welded on The end face of the semi-arc bottom plate; the semi-arc seat cover is installed on the semi-arc rear seat through the threaded hole on the skirt. The invention has the advantages of accurate welding size and wide applicability.

Description

technical field [0001] The invention relates to an adjustable auxiliary frame supporting device of a mining dump truck, which belongs to the field of mining machinery. Background technique [0002] Mining dump trucks have become an indispensable means of transportation for various projects and infrastructures such as earthwork construction and mine mining in various countries. Electric drive dump trucks above 100 tons often assemble the generator, engine and radiator into an independent powertrain, which is fixed on the frame through the power sub-frame to realize the disassembly and maintenance of the entire powertrain. The sub-frame of the powertrain needs to be installed on the inner side of the frame longitudinal beam through several support seats. The rear support seat of the existing sub-frame is usually directly welded on the inner web of the frame longitudinal beam. Considering the welding process of the frame Welding deformation will occur, so that the welding size...
