Complete interchanging quick fix tower section K lever welding fixture

Abstract

The invention relates to a completely interchangeable welding tool set of a packaged tower-section K-shaped bar, which comprises a frame and a location device; wherein, the frame is a support framework formed by the connection of I-shaped steel beams; the location device is arranged at the upper part of the frame and comprises a location bracket and a location plate; a concave location plate is fixed on a location bottom plate which is arranged at the upper part of a K-shaped connection position of the steel beam of the frame; L-shaped location plates are respectively fixed on the upper surfaces of the location bottom plate and the steel steam of the frame; a support plate is arranged between the L-shaped location plate and the steel beam of the frame; the location bracket is respectivelyfixed on the position of four butt joint corners on the upper end surface of the frame. The welding tool set which is supported by taking the frame as a body is located by the location bracket, a location pin and the location plate and adopts a fixed bolt and a press plate as clamping tools so as to ensure the precise corresponding positions of each part, which can realize the interchange of the components welded on the welding tool set. The welding tool set has the advantages of improving the assembly quality, reducing the out-of-tolerance deformation, solving the transportation problem, improving the work efficiency, realizing highly efficient interchange, etc.

Description

technical field [0001] The invention relates to a welding tool for tower crane components, in particular to a fully interchangeable and fast-installed tower section K-shaped rod welding tool. Background technique [0002] At present, in the manufacturing and welding process of the crane tower section, in addition to the four main chords as the main bearing load, a considerable part of the load is carried by the web system between the main chords. The connection of this part of the web system is usually welded and assembled by means of actual matching. The shortcoming of this connection method has three aspects; 1. The size error and deformation of each part of the tower section after welding are large. 2. When the main chord and the web system are welded into one, it will be bulky and difficult to transport, and the work efficiency will be low. 3. When the rods are deformed or damaged, it is difficult to match and the interchangeability is poor. This is also a common prob...
