Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the large bridge crane assembly correcting device comprises a four-leg support, wherein the four-leg support comprises a first upright column 1, a second upright column 2, a third upright column 3 and a fourth upright column 4 which are sequentially connected in a surrounding manner.

Equal sliding fit sets up between first stand 1 and the 2 bottoms of second stand and between third stand 3 and the 4 bottoms of fourth stand and carries out transverse connection on diaphragm 5 down, and diaphragm 5 is down through the track groove that sets up and first stand 1, second stand 2, third stand 3 and the 4 sliding fit of fourth stand for diaphragm 5 down with the concrete sliding mode of stand to the bottom shape and the track groove looks adaptation of first stand 1, second stand 2, third stand 3 and fourth stand 4.

All set up through sliding fit between first stand 1 and the 4 tops of fourth stand and between second stand 2 and the 3 tops of third stand and go up diaphragm 6 and carry out longitudinal connection, go up the concrete sliding fit mode of diaphragm 6 and be connected with first stand 1 through the sliding sleeve at 6 both ends of diaphragm, second stand 2, third stand 3 and fourth stand 4, and first stand 1, second stand 2, third stand 3 and fourth stand 4 all are equipped with a set of screw hole 9 with bolt fit, the sliding sleeve is fixed to the bolt, thereby it can slide from top to bottom to go up diaphragm 6.

In order to correct a plurality of directions of the box-shaped beam of the bridge crane in the assembling and correcting process of the box-shaped beam of the bridge crane, namely, the four-foot bracket is sleeved in the box-shaped beam of the bridge crane, and has a correcting function on the left and right directions and the upper part of the box-shaped beam of the bridge crane. Therefore, the first transverse plate 7 is in sliding fit between the upper transverse plates 5, the second transverse plate 8 is in sliding fit between the first stand column 1 and the fourth stand column 4 and between the second stand column 2 and the third stand column 3, and the first transverse plate 7 and the second transverse plate 8 are fixedly connected with the jack power assisting device.
