Adopt the utility model has the advantages of, the structure is light, and the wholeness is strong, can satisfy many people high altitude welding operation simultaneously, and the welder of being convenient for carries out welding operation to each position, and the welding deformation of effective control component has greatly improved welding operation efficiency.
Furthermore, each hanging cage is composed of four vertical rods vertically arranged in the longitudinal direction and a connecting rod with the bottom connected with the four vertical rods.
Furthermore, the vertical rod is provided with a hole for the safety rope to pass through.
Furthermore, a vertical surface perpendicular to the vertical surface on the inner side of the hanging cage is provided with a ladder stand, and the vertical surface opposite to the vertical surface provided with the ladder stand is not provided with the ladder stand.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, which are included to illustrate and not to limit the invention.
A high-altitude welding hanging cage for a large-section box beam comprises 6 channel steels, 28 angle steels, 8 round steels and 12 springboards. The utility model discloses the channel-section steel specification of well adoption is [10, and the angle steel specification is L63 star 5, and the round steel specification is ∅ 12, and the actual height and the length of channel-section steel and angle steel can be confirmed according to the actual cross-section size of on-the-spot big cross-section box roof beam.
Referring to fig. 1 to 5, two transverse rods 1 (channel steel) and two longitudinal rods 2 (channel steel) are welded to form a rectangular frame which is erected on the top surface of the large-section box-type beam, two connecting longitudinal rods (channel steel) which are parallel to the length direction of the large-section box-type beam and have an interval larger than the width of the large-section box-type beam are symmetrically welded on the inner side of the rectangular frame, and the connecting longitudinal rods are equidistant to the inner side surface of the large-section box-type beam respectively. The rectangular frame is assumed on the large-section box-type beam and is used for hanging the hanging cages 3 symmetrically arranged at the two ends of the cross rod 1.
Each hanging cage 3 is composed of four vertical rods (angle steel) vertically arranged in the longitudinal direction and connecting rods (angle steel) with the bottoms connected with the four vertical rods. Two connecting rods (angle steels) are welded at the bottoms of the vertical rods, two springboards 5 are laid above the connecting rods to form a lower operating platform 6-1, and the height of the lower operating platform 6-1 is lower than that of the bottom surface of the large-section box-shaped beam. And a springboard 5 is laid at the bottom of the vertical surface of the outer side of the hanging cage 3. In addition, the middle parts of the vertical rods of the hanging cage 3 are also connected through connecting rods (angle steel), two springboards 5 are laid above the angle steel to form a middle operating platform 6-2, and similarly, one springboard 5 is also laid in the middle part of the vertical surface outside the hanging cage 3, so that the safety protection effect of the hanging cage is improved.
In order to facilitate the movement between the lower operating platform 6-1 and the middle operating platform 6-2, a vertical surface vertical to the inner vertical surface of the hanging cage 3 is provided with a plurality of equidistant ladder stands 4 (round steel) for workers to climb, the ladder stands are made of round steel, and the other vertical surface opposite to the vertical surface is not provided with round steel for the operators to go in and out of the operating platform. In addition, set up the trompil in the pole setting of hanging cage 3 for hang the safety rope around hanging cage 3, thereby ensure constructor's personal safety.
When the large-section box beam and the steel column bracket are installed in place and welding work is required, the high-altitude welding suspension cage for the large-section box beam is placed at the joint of the large-section box beam and the steel column bracket by using a crane. A welder can horizontally lay on the springboard 5 of the lower operating platform 6-1 to weld the lower flange interface welding seam of the large-section box beam, and can stand on the lower operating platform 6-1 to weld the vertical interface welding seam. When the height of the cross section is too large, a welder can not reach the interface welding seam on the upper part of the vertical surface on the springboard 5 of the lower operating platform 6-1 for welding operation, the ladder stand 4 arranged on the vertical surface of the hanging cage can climb to the middle operating platform 6-2, the interface welding seam on the upper part of the vertical surface is welded on the pedal of the stand, and the ladder stand 4 can also climb to the upper flange of the box-shaped beam with the large cross section for welding butt welding.
The utility model discloses an under the prerequisite of guaranteeing safety, utilize limited high altitude construction space as far as possible for the welder provides the welding jobs condition of being convenient for, the welding deformation of effective control component has greatly improved welding jobs efficiency.
The above description is only some specific embodiments of the present invention, and the present invention is not limited thereto. Various modifications and changes made by those skilled in the art without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
