Problems solved by technology

If this kind of joint is used for the connection of the undercarriage structure of the special crane for wind power installation, due to the large size and the large number of bolts, the assembly construction is difficult, time-consuming and laborious, which will seriously affect the on-site assembly work efficiency of the crane
As a result, the installation cycle of wind turbines and the production cycle of putting into power generation are prolonged, so it may delay the opportunity to use and play the best season of wind power

Abstract

The invention provides a quick assembling coupling for connecting box-beam steel structure modules, which is characterized by comprising a plurality of segments or pieces of box-beam steel structure modules for forming a box-beam component, wherein, quick assembling couplings (3) are symmetrically arranged at abutting ends of every two adjacent box-beam steel structure modules. Each quick assembling coupling comprises up and down enclosed flange connection boxes (12, 13), a plurality of shear-resistant positioning pin holes (10) and a plurality of stud hole tubes (9), wherein, the up and down enclosed flange connection boxes (12, 13) are arranged at the abutting ends of the box-beam steel structure modules; the shear-resistant positioning pin holes (10) are used for penetrating shear-resistant positioning pins (15); and the stud hole tubes (9) are arranged side by side in each enclosed flange connection box and used for penetrating double end studs (14).

Description

Technical field [0001] The invention relates to a quick joint used for connecting box girder steel structure modules. The quick joint can be widely used to make various box girder components, such as various bridge erecting machines, wind generator installation cranes and other large construction machinery main structures Fast assembly connection between the sections or block-type box girder steel structures. Background technique [0002] In all kinds of large construction machinery, such as bridge erecting cranes, tire-type boom cranes and long and large hydraulic suspension power flatbed transport vehicles, etc., due to their large structure, they are not suitable for driving on roads, and need to be disassembled by long-distance automobile transportation At the site of use, they are reassembled again, that is, their main structure is divided into several independent assembly and transportation units (modules), and the modules are connected by removable joints. In order to ill...
