[0002] At present, steel structures are mainly composed of steel materials. They are one of the main types of building structures and are widely used. Steel structure objects need to be drilled by a drilling device during processing, so that fasteners such as bolts can be assembled through the holes.

[0003] In the prior art, a steel structure drilling device with application number 202320605948.4 includes a magnetic base, a column is installed on the upper wall of the magnetic base, a horizontal plate is installed on the upper end of the column, a through hole is provided on the lower wall of the horizontal plate away from the magnetic base, a pressure rod is slidably inserted in the through hole, a bracket is fixedly installed on the side wall below the pressure rod, a motor is provided on the bracket, and a drilling tool is installed on the driving end of the motor. The utility model relates to the field of steel structure processing technology. The device has a compact structure and is easy to carry. It can be used in construction sites to meet the needs of different working conditions. The magnetic base can be used to quickly adsorb the equipment to the surface of the steel structure, and different working conditions can be quickly switched through the positioning component. The setting of the dust reduction component can prevent the dust generated during drilling from flying around and polluting the environment, which brings convenience to people's use.

The support plate can be easily driven to move, thereby improving work efficiency; at the same time, the first water pipe sprays water toward the drilling location through the nozzle. When the drilling cutter contacts the steel material, the steel structure squeezes the drilling cutter. At this time, the drilling cutter is forced to drive the bracket to move upward, and the movement of the bracket drives the second side plate to move and buffers the squeezing of the second spring. After the drilling is completed, the pressure rod is released and the first circular plate is driven to move upward by the elastic force of the first spring. The first circular plate moves upward and drives the support plate back through the first guide rod, which plays a buffering and protective role for the drilling cutter when drilling again, thereby increasing the service life of the drilling cutter.

The setting of the blocks 146 protects the second spring 145 and prevents the second spring 145 from being over-extruded and deformed, thereby causing damage.

[0028] In some specific implementation schemes, a third side plate 150 is fixedly installed on one side of the support plate 131, and a first water pipe 151 is fixedly installed on the bottom end of the third side plate 150.

[0029] Working principle: When in use, the device can be fixed to a suitable position of the steel structure through the magnetic base 110 according to the point to be processed. The structure of the magnetic base 110 is the same as that in the comparative document 202320605948.4. Before drilling, first put one end of the water inlet pipe with a water source on the connecting head 152, start the motor 141 to drive the drilling cutter 142 to rotate, lift the pressure rod 127 to drive the support shaft 123 to rotate through the cross bar 125 and the support block 124, and at the same time, the cross bar 125 rotates with the support shaft 123 as the axis and drives the support plate 131 to move downward through the pull rod 126, and the support plate 131 moves downward. The bracket 140 is driven to move downward, and the downward movement of the bracket 140 drives the drilling cutter 142 to move downward for drilling. At the same time, the first water pipe 151 sprays water to the drilled hole through the nozzle. When the drilling cutter 142 contacts the steel material, the steel structure will squeeze the drilling cutter 142. At this time, the drilling cutter 142 is forced to drive the bracket 140 to move upward. The movement of the bracket 140 drives the second side plate 143 to move and buffers the squeezing of the second spring 145. After the drilling is completed, the pressure rod 127 is released and the elastic force of the first spring 134 drives the first circular plate 133 to move upward. The upward movement of the first circular plate 133 drives the support plate 131 to move back through the first guide rod 132.
