Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] An on-site welding tool for traveling I-shaped beams in a steam turbine house, including a web 1, a lower flange 2 and an upper flange, the web 1, the lower flange 2 and the upper flange are connected by spot welding For an I-shaped beam, an anti-deformation fixture plate 3 is sleeved on the lower flange plate 2, and an inverted T-shaped groove 7 is arranged on the top surface of the anti-deformation fixture plate 3. Left positioning wedge embedded groove 8, middle positioning wedge embedded groove 9 and right positioned wedge embedded groove 10 are respectively provided on the groove bottom surface of the groove, and left positioning wedge embedded groove 8 is provided with left positioning wedge Block 4, the upper top surface of the left positioning wedge block 4 is connected to the lower bottom surface of the lower flange plate 2, and the middle positioning wedge blo...

Abstract

The invention discloses a field welding tool for a traveling I-shaped beam and an assembling and welding method of the field welding tool. The problem that a flange plate is prone to deformation when a web and the flange plate of the traveling I-shaped beam are welded is solved. A lower flange plate (2) is sleeved with anti-deformation clamp plates (3); an inverted-T-shaped groove (7) is formed in the top face of each anti-deformation clamp plate (3); a left positioning wedge block embedding groove (8), a middle positioning wedge block embedding groove (9) and a right positioning wedge block embedding groove (10) are formed in the groove bottom face of each inverted-T-shaped groove (7); wedge blocks are arranged in the three grooves correspondingly; the upper top faces of the wedge blocks are connected to the lower bottom face of the lower flange plate (2) in an abutting manner; and the lower flange plate (2) is sleeved with the anti-deformation clamp plates (3) at intervals in the front-back longitudinal direction of the web (1). Welding deformation of the flange plate is greatly reduced, and straightening of the I-shaped beam obtained through subsequent welding is omitted.

Description

technical field [0001] The invention relates to a welding tool, in particular to an on-site welding tool for an I-shaped beam used in a steam turbine room of a thermal power plant and a method for assembling and welding the tool. Background technique [0002] In the equipment installation of the steam turbine room of a newly-built thermal power plant, it is necessary to set up a driving beam for driving on the top of the machine room. The driving beam is an I-shaped beam, which is generally completed on-site with steel plate processing and welding. The on-site production process is as follows: first The web, upper flange and lower flange of the I-shaped beam are processed separately with steel plates, and the three steel plates are spot welded together to form the I-shaped beam. At the joint with the web, perform groove connection welding of the welds on both sides; during groove welding, because the flange plate on the outer side of the weld is narrow, the welding heat is r...
