Ring beam rivet weld device for mining dumper

Abstract

The invention discloses a ring beam rivet weld device for a mining dumper, which is characterized by comprising an installation platform matched with a ring beam structure, wherein a centralized positioning structure is arranged on a central line of the installation platform, corresponding to a middle lower steel casting of a ring beam; a central measuring basis structure is arranged on the middle part of the installation platform on the central line; a fixed positioning structure is arranged on the right side of the central measuring basis structure; a movable positioning structure is arranged on the left side of the central measuring basis structure; the fixed positioning structure and the movable positioning structure are arranged symmetrically; the installation platform is provided with an observing block matched with steel castings of the ring beam; a movable positioning plate structure is arranged on the outer side of the observing block; and the installation platform is provided with a compaction structure matched with the ring beam. The ring beam rivet weld device can position ring beam assemblies conveniently, reduce the welding errors of the ring beam effectively, ensurethe welding quality of the ring beam and improve the efficiency.

Description

technical field [0001] The invention relates to a welding tool, in particular to a riveting and welding device for a mining dump truck rim beam. Background technique [0002] The mining dump truck is a mining transport vehicle, which belongs to one of the mining equipment. It is mainly used for the transportation of ore and other bulk materials in the mine. The working conditions of the mining dump truck are very harsh, and the frame is used as the base of the whole vehicle. It is the core component of the mining dump truck. It not only connects and supports other major parts, but also bears the vehicle itself and various loads. Its importance in the whole vehicle is self-evident. [0003] The commonly used mining dump truck frame and suspension cylinder structure are welded by steel plates and round pipes of various thicknesses and shapes, generally including bumper assembly, front longitudinal beam assembly, ring beam Assembly, rear longitudinal beam assembly, torsion tub...

AI Technical Summary

Problems solved by technology

In the past, the ring beam of mining dump trucks used integral castings. Due to the complex shape of the castings, it is easy to cause large errors in the ring beam after casting, and casting is prone to many casting defects such as shrinkage cavities, porosity, pores, slag inclusions, and cracks. The quality is difficult to guarantee, which seriously affects the quality of the ring beam, which in turn affects the performance of the frame and the whole vehicle

[0004] In response to the above shortcomings, ring beams are now generally used in separate casting and then welded together, such as figure 1 As shown, the ring beam consists of ring beam upper castings 15 (one left and right symmetrical), upper beam parts 16 (steel plate weldments), ring beam lower left steel castings 17, ring beam lower right steel castings 18, ring beam middle lower Steel casting 19 is composed of 5 steel castings and 1 welded steel plate. Each steel casting is provided with 3~4 processed positioning bosses. When welding together, the steel castings of the ring beam require These positioning bosses must be on a plane, and the ring beam after welding should maintain the squareness and various size requirements. However, there is currently no complete device for ring beam welding, and it can only be measured and welded manually. This is a great waste of manpower, the welding efficiency is not high, and errors will inevitably occur, resulting in the failure of ring beam welding to meet the requirements, affecting the quality of the ring beam, and further affecting the performance of the frame and the entire vehicle
