Description

Technical Field

[0001] The invention relates to the field of tower crane parts processing equipment, and in particular to a processing device for maintaining the docking accuracy of a connecting sleeve of an outer wall of an attachment rod of a tower crane. Background Art

[0002] The standard section of the tower crane is erected on the outside of the building. In order to ensure the erection strength of the standard section of the tower crane, an attachment rod is arranged between the outer wall of the building and the standard section. The strength of the standard section is ensured by the attachment rod. However, due to the different distances between the standard section and the wall, the required lengths of the attachment rods are inconsistent. When the distance between the standard section and the wall of the outer wall is greater than the length of the attachment rod, multiple sections of the attachment rods are required to be butt-jointed. The butt-jointed between the attachment rods requires that sleeves are fixed on the outer walls at both ends of the attachment rods, and bolts are inserted into the sleeves to achieve the butt-jointed between the two attachment rods. That is, when the sleeves are welded on the attachment rods, the distance between the sleeves needs to be ensured, so that when the two attachment rods are butt-jointed, the multiple sleeves on the attachment rods are opposite, which is convenient for the butt-jointed between the two sleeves. Now, the welding sleeve on the attachment rod requires that the sleeve be put on the mold, and then the sleeve is manually welded to the outer wall of the attachment rod, so that the processing efficiency of the attachment rod is relatively low. At the same time, the staff needs to put the sleeve on the mold, and then clamp the attachment rod between the multiple sleeves, and then weld it by the staff, so the operation intensity of the staff is relatively large.
