Embodiment Construction
[0028] The following examples can make the skilled artisan of the present invention more fully, but will not be limited to the scope of the embodiments.
[0029] Such as figure 1 figure 2 The orbital tank beam is solder beam and the square steel rail welding process. The specific process is as follows: including S1: square steel rail docking welding; S2: Fang Steel track and the carrier beam positioning fixation; S3: Bear beam and party Welding of steel orbits; S4: The beam panel is completely cut;
[0030] S1: Fang Steel Track 1 Dip Welding:
[0031] S1.1: Welding should be hotly cut in a direction perpendicular to the square steel rail axis, ensuring the incision smooth, and polished the end face of the incision, thoroughly remove the oxidation of the oxide; use the track to connect the tool to the track, and put the steel on the docking pad liner;
[0032] S1.2: Preheating to 80-120 ° C before welding, welding the docking rail end portion with manual arc welding and electrode,...

The invention relates to a welding process of a rail-supporting girder of a rail crane and a square steel track, which is characterized in that: the specific process is as follows: including S1: butt welding of the square steel track; S2: positioning and fixing the square steel track and the support beam; S3: bearing The welding of the rail beam and the square steel track; S4: the rail beam panel is completely cut off; the rail beam in the present invention does not need to be prefabricated, which reduces the production cost; the rail beam does not need to be prefabricated, which reduces the manufacturing cycle of the The production node of the girder will be affected by the prefabrication of the rail-bearing beam; the square steel track of the trolley is installed and welded to the surface of the rail-bearing beam on the ground tire frame, which realizes low-cavitation construction, reduces safety risks, protects the safety of workers, and reduces the labor intensity of workers; The square steel track does not need to be assembled and welded after the four sides of the girder are formed, and it also avoids a large amount of internal stress caused by the welding box, and reduces a large amount of calibration work after the deformation of the girder box is out of tolerance.
Description
Technical field [0001] The present invention relates to the field of welding techniques of orbital hanging lacing beams, and more particularly to a rail hanging laminate beam and a square steel rail welding process. Background technique [0002] The beam structure of the orbit tulldone door is designed between the upper plate and the inner belle, mainly used to install the trail track of the cradle of the carrier, and the T-type carrier beam basically has two forms: one is It can be used to form a T-type carrier beam by standard H-shaped steel procurement; the other is a non-standard H-type steel requires prefabrication, and one is divided into two forming rail beams; the cart mounted on the carrier beam There are two forms in the track: one is to use the pressure plate to mount the standard profile track, which does not need to be welded to the carrier beam bracket; the other is a square steel track that needs to be welded to the carrier beam; the traditional carrier beam is dir...
