Two-way double-ended horizontal type drilling system for H-shaped steel column

Abstract

The invention discloses a two-way double-ended horizontal type drilling system for an H-shaped steel column, and belongs to the technical field of drilling equipment. The two-way double-ended horizontal type drilling system comprises a machine body (2) as well as an electrical unit (1) and a drilling device assembly (7) which are arranged on the machine body (2), wherein the machine body (2) comprises a horizontal machine body part and side walls which are symmetrically arranged at the two sides of the bottom of the machine body; a slide path (6) is arranged on the bottom of the machine body;slide rails (9) which are distributed in the forms of triangular rectangular coordinates are at least arranged between the bottom of the machine body and one side wall; and the drilling device assembly (7) is equipped with a plurality of drill bits (71). The two-way double-ended horizontal type drilling system for the H-shaped steel column disclosed by the invention guarantees accuracy and consistency of a drilling position; the drilling device assembly is stable in transmission while moving on the slide path, and is small in shake, so that feeding precision of the drill bits is effectively improved; and the drilling device assembly performs symmetrical or asymmetric drilling in the two sides of wing plates at the two sides of the H-shaped steel column, and is very high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment, and more specifically relates to an H-shaped steel column bidirectional double-head horizontal drilling system. Background technique [0002] Among the various workpieces of the steel structure, the H-shaped steel column is made of H-shaped steel as the basic material. Generally, H-shaped steel is composed of two flanges and webs, and has the characteristics of high resistance (bending strength) to bending moment in a specific direction, simple structure, easy processing, transportation, etc., and is used in construction, railway transportation and other industries very broad. With the expansion of the scale of my country's high-speed rail, H-shaped steel columns are used as the main catenary support device, and the number required is increasing. [0003] Such as figure 1 As shown, the H-shaped steel column is generally used as a supporting structure due to its high structural stren...

Problems solved by technology

[0004] The drilling machine disclosed in this patent solves the problem of drilling holes in multiple directions of the H-shaped steel column, but there are still some deficiencies: as the structural size of the H-shaped steel column is relatively large and the thickness is relatively large, so in the drilling process, the drill The impact load of the drilling machine on the workpiece is relatively large, which may easily cause the body of the drilling machine to vibrate greatly during the drilling process, the workpiece will shake, the precision of the drill bit is low, and it is difficult to ensure the accuracy and consistency of the drilling position; secondly, the drill The hole machine can only drill one hole or a maximum of three holes at a time, and can only drill symmetrically. It cannot process H-shaped steel columns that require asymmetrical holes, and the efficiency is very low when producing products that require multiple holes in each direction. It does not meet the requirements of large-scale production. In addition, because the H-shaped steel is made of steel, it is very heavy. A complete steel can weigh more than 700kg. If a series of holes need to be drilled on it, the door-shaped frame needs to be moved as a whole. Time-consuming and labor-intensive, and the processing efficiency is not high
