Embodiment Construction

[0019] The present invention is described in detail in conjunction with the accompanying drawings:

[0020] Such as figure 1 The shown steel structure cross column web drilling equipment mainly includes a column support 8, a geared column 7, a cross arm 6 and a transmission assembly. Wherein, the geared pillar 7 is fixed on the column support 8, the cross arm 6 is perpendicular to the axis of the geared pillar and fixed on the geared pillar 7, and the top of the geared pillar 7 is provided with a lifting motor 1 for adjusting the height of the cross arm.

[0021] The transmission assembly includes a drilling machine motor 2, a belt 3, a belt 4 and a drill bit assembly 5. The drilling machine motor 2 is arranged on one end of the cross arm 6 , and the drill bit assembly is arranged on the other end of the cross arm 6 . The belt pulley 3 is arranged on the drilling machine motor 2, and the belt 4 is connected with the belt pulley 3 and the drill bit assembly. The drill assemb...

Abstract

The invention provides a hole forming device for a steel-structure cross-section column web. The hole forming device comprises a stand column support, a supporting column with a gear, a transverse arm and a transmission assembly. The supporting column with the gear is fixed to the stand column support. The transverse arm is perpendicular to the axis of the supporting column with the gear, and is fixed to the supporting column with the gear. A transverse arm regulation handle used for regulating the punch position is arranged on the transverse arm. A lifting motor used for regulating the height of the transverse arm is arranged at the top end of the supporting column with the gear. The transmission assembly comprises a drill machine motor, a belt disk, a belt and a drill bit assembly. The hole forming device fills in the blank that no special hole forming devices exist, and holes of webs of various cross-shaped columns with different sections can be formed; the electromagnetic relay principle is adopted, and the device can be attached to flange plates of three faces of a cross-shaped column; the hole forming precision is improved, the machining program of crosses is reduced, the onsite installation punching rate is better ensured, and component overturning is reduced.

Description

technical field [0001] The invention relates to a hole-making equipment for a cross-column web of a steel structure, in particular to a drilling machine for making high-strength bolt holes for cross-column webs of different cross-sections in a steel structure. Background technique [0002] With the increasing maturity of steel structures, in more and more large-scale buildings and high-rise building steel structures, various cross-section cross columns are one of the important structural forms, and the fabrication of high-strength bolt holes in the web of steel structure cross columns is a One of the basic procedures. [0003] Because in construction, cross columns of various cross-sections often appear, and the webs of cross columns have many high-strength bolt holes. The three-dimensional drilling machine can only process H-shaped, box-shaped and cross-shaped column flange plate holes, but the cross column mainly has more high-strength bolt holes in the web, and the flang...
