[0013] The specific implementation of the utility model is further explained in detail in combination with the drawings.

[0014] By Figures 1 to 2 It is given, a kind of adjustable platform device for submerged arc corner welding machine, including support leg 1, support leg 1 is slidably connected with crossbeam 2, crossbeam 2 right end is hinged with platform 3, and platform 3 right end surface is equipped with multiple positioning blocks 4, and the main beam web of crane is equipped on the right side of platform 3, and positioning block 4 is overlapped with the main beam web, and submerged arc corner welding machine is placed on platform 3.

[0015] In order to improve the stability of support leg 1, the support leg 1 is a circle structure welded by round pipe.

[0016] In order to facilitate platform 3 collection carrying, multiple hinges 5 are connected between the crossbeam 2 and the platform 3.

[0017] The sleeve 6 is fixed on the both ends of the crossbeam 2, the sleeve 6 slides up and down along the support leg 1, and the fastening bolt 7 corresponding to the support leg 1 is installed on the sleeve 6.

[0018] In order to guarantee the stability of positioning block 4 and the main beam web, mounting hole 8 is equipped on positioning block 4, magnetic chuck is fixed in mounting hole 8, and magnetic chuck and the main beam web attract each other.

[0019] The utility model discloses when using, loosen fastening bolt 7, sleeve 6 is slid on support leg 1, according to the height of the web of girder, the height of crossbeam 2 on support leg 1 is adjusted, when the upper surface of platform 3 is flush with the upper surface of the web of girder, tighten fastening bolt 7, with sleeve 6 and crossbeam 2 are fixed on support leg 1, then positioning block 4 and the web of girder overlap, and the magnetic chuck is fixed in mounting hole 8, and the magnetic chuck and the web of girder attract each other, make platform 3 and the web of girder steady together,

[0020] When the outer fillet weld of the girder of the crane is welded by using the submerged arc fillet welding machine, the submerged arc fillet welding machine adopts a semi-automatic submerged arc welding machine, the semi-automatic submerged arc welding machine comprises a welding trolley and a submerged arc welding machine, and due to the limitation of the structure, the welding trolley runs in front, and the welding torch of the submerged arc welding machine follows behind; when the welding trolley reaches the end of the web of the girder, the welding trolley continues to run on the platform 3, so that the welding torch of the submerged arc welding machine can weld the fillet weld of the girder at one time, and the welding quality is guaranteed.

[0021] After welding, the submerged arc fillet welding machine is separated from the platform 3, the magnetic chuck is separated from the web of the girder, and the platform 3 can be folded on the support leg 1, so that the flexibility is good, and in addition, a plurality of casters can be installed at the bottom of the support leg 1, so that the support leg 1 is convenient to transport.

[0022] The embodiment is not limited in shape, material, structure or the like in any form, and any simple modification, equivalent change and modification made according to the technical essence of the utility model to the above embodiment are within the protection scope of the utility model technical scheme.
