Problems solved by technology

The existing jibs are all steel structures, which mainly have the following disadvantages: 1. The existing jibs are all made of steel, which is heavy and the load is relatively reduced; 2. The jibs are welded, and in open-air production It is easy to corrode and form gaps, which will affect the strength of the boom
However, there is currently no effective process for how to process aluminum

Abstract

The invention aims at providing a method for manufacturing a boom by using aluminum alloy sections, the boom and a pump truck using the boom provided by the invention. The technical scheme is that the boom manufacturing method comprises the steps of extruding the aluminum alloy sections; performing variable-cross-section treatment to the aluminum alloy sections, i.e. removing partial materials at positions which bear small force to form cross sections with different sizes. The boom provided by the invention is formed by performing bending treatment and variable-cross-section treatment to the aluminum alloy sections and comprises a main body and a head which form a preset included angle. The pump truck provided by the invention uses the boom provided by the invention.

Description

technical field [0001] The invention belongs to the technical field of pump truck booms, and in particular relates to a method for manufacturing a boom, a boom manufactured by the method and a pump truck using the boom. Background technique [0002] The pump truck is a machine that uses pressure to continuously transport concrete to a certain height along the pipeline. Therefore, the arm frame is an important part of the pump truck conveying mechanism, and the weight, strength, and compactness of the arm frame directly affect the conveying capacity. The existing jibs are all steel structures, which mainly have the following disadvantages: 1. The existing jibs are all made of steel, which is heavy and the load is relatively reduced; 2. The jibs are welded, and in open-air production It is easy to corrode and form gaps, which will affect the strength of the boom. Therefore, the use of materials that are lighter than steel and corrosion-resistant to make the arm frame can avo...
