起重机臂架的制作方法

Method for manufacturing crane arm support

Abstract

The invention discloses a method for manufacturing a crane arm support. The method comprises the following steps of: 1, dividing the crane arm support into a head, a middle and a root, wherein the head is mainly of a box beam structure, the middle is mainly of a truss structure, and the root is mainly of a combined structure of trusses and a variable-section box body; 2, constructing a low assembled scaffold which comprises a horizontal scaffold and a low scaffold; 3, hanging the head, the middle and the root to the low assembled scaffold; 4, with the center line of the arm support as a reference, assembling the middle part at first, then assembling the root, and finally assembling the head, wherein the head, the middle and the root are all fixed on the low assembled scaffold; and 5, integrally lifting the head, the middle and the root, and assembling a high assembled scaffold. According to the technical scheme, the method for manufacturing a large-size crane arm support is provided, so that a crane with heavy weight and large size can be manufactured conveniently.
本发明揭示了一种起重机臂架的制作方法,包括:步骤一,将起重机臂架分为头部、中部和根部,其中头部以箱梁结构为主、中部以桁架结构为主、根部以桁架与变截面箱体的组合结构为主;步骤二,搭建低拼装胎架,其包括水平胎架和低胎架;步骤三,将头部、中部及根部吊装至低拼装胎架上;步骤四,以臂架的中心线为基准,先拼装中部,再拼装根部,最后拼装头部,头部、中部与根部均与低拼装胎架固定;步骤五,将头部、中部和根部整体抬高,安装高拼装胎架。采用了本发明的技术方案,能够提供一种大型起重机臂架的制作方法,从而能够便于制作大重量、大尺寸的起重机。
