Embodiment Construction

[0014] Such as figure 1 As shown in the figure, an overturn frame for welding the main girder of a crane includes a longitudinal support plate 6 and a transverse support plate 7 for fixing the main girder 1, and the longitudinal support plate 6 is fixed by a “V”-shaped rib plate 4 and the turning circle 3 Above, the transverse supporting plate 7 is fixed on the turning ring 3 by the bolt 2, the turning ring 3 is rollingly matched with the two turning frame support wheels 5, and the two turning frame supporting wheels 5 are respectively connected to the corresponding turning bracket 8 in rotation.

[0015] "V" font ribs 4 are four groups, and every two groups of "V" font ribs 4 fix one side longitudinal supporting plate 7 on the turning circle 3.

[0016] The direction of the supporting force of the two overturning brackets 8 forms an angle of 50°-70°.

[0017] The overturn frame supporting wheel 5 is a cylinder, and the side surface of the cylinder has a groove, and the groov...

Abstract

The invention discloses a roll-over stand for welding a girder of a crane, which comprises a longitudinal supporting plate and a transverse supporting plate, wherein the longitudinal supporting plate is used for fixing the girder and is fixed on a roll-over ring through a V-shaped rib plate; the transverse supporting plate is fixed on the roll-over ring; two supporting wheels on two roll-over supports are matched in a rolling manner; the two supporting wheels are in rotational connection with the two roll-over supports respectively. According to the invention, as the girder is fixed in the roll-over ring in rolling connection with the supporting wheels on the two roll-over supports, and the roll-over ring rolls on the supporting wheels on the roll-over supports to realize the purpose that the girder overturns during welding, the welding efficiency and quality are greatly improved after the girder is overturned by the roll-over stand instead of a rope.

Description

technical field [0001] The invention relates to the field of crane production, in particular to a crane welding device. Background technique [0002] At present, in the welding of crane girders, the main girder is usually turned over with ropes for welding, but when turned over with ropes, it is not easy to turn over to the required position, which affects the welding efficiency, and the turning of the ropes is not firm, which affects the welding quality. Contents of the invention [0003] In order to improve the work efficiency and the quality of the welded main beam, the invention provides an overturning frame. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] An overturn frame for crane main girder welding, including a longitudinal supporting plate and a transverse supporting plate for fixing the main beam, the longitudinal supporting plate is fixed on the turning circle through a “V” shaped rib p...
