Beam body butting assembly fixture

Abstract

The invention discloses a beam body butting assembly fixture, which comprises a door-shaped frame, supporting blocks and lifting devices, wherein the supporting blocks are arranged at the bottom of the door-shaped frame, and are used for supporting the ends of a workpiece to be subjected to butting assembly on the inner side of the door-shaped frame; and the lifting devices are used for at least lifting the supporting blocks relative to the ends of the workpiece, so that the ends of the workpiece are leveled to be subjected to the butting assemble. According to the beam body butting assembly fixture, the lifting devices are operated, so that the assembly ends of the workpiece can be supported by the supporting blocks, and are leveled and subjected to butt joint in the door-shaped frame; during assembly, the surface of the workpiece is not damaged, and work of polishing and cleaning is not needed; furthermore, the labor resources can be saved; and the environment pollution can be reduced.

Description

technical field [0001] The invention relates to an assembly tool, in particular to a beam body butt joint assembly tool. Background technique [0002] In the process of building bridges and railways, it is often necessary to carry out butt-joint assembly of various beam structures, such as steel box girders, turnout beams, etc., which usually require high assembly accuracy and surface quality to ensure performance, while the existing technology In the butt joint assembly of the beam structure, the turnbuckle is usually used in conjunction with the erection board to use the hammer and the iron needle to carry out the assembly work. The auxiliary plate welded on the workpiece to maintain and ensure the accuracy. After the workpiece is assembled, it needs to be cut and removed. Therefore, a large number of welding points and residual materials will be produced after extensive use of the plate, that is, "horse feet", which need to be polished by grinding. The removal of "horse ...

[0002] In the process of building bridges and railways, it is often necessary to carry out butt joint assembly of various beam structures, such as steel box girders, turnout beams, etc., usually requiring high assembly accuracy and surface quality to ensure performance, while the existing technology In the butt joint assembly of the beam structure, the turnbuckle is usually used in conjunction with the erection board to use the hammer and the iron needle to carry out the assembly work. The auxiliary plate welded on the workpiece to maintain and ensure the accuracy. After the workpiece is assembled, it needs to be cut and removed. Therefore, a large number of welding points and residual materials will be produced after extensive use of the plate, that is, "horse feet", which need to be polished by grinding. The removal of "horse feet" requires a large amount of grinding work, which requires a lot of manpower, and a large amount of powdery debris is generated during the grinding process. The working environment is harsh and the pollution is serious, and obvious marks will be left after grinding, and the surface quality is poor. Difference
