Punching device for steel structure rod piece for building

Abstract

The invention relates to the field of building construction, in particular to a punching device for steel structure rod pieces for buildings. The punching device comprises a motor; an output shaft isinstalled at the upper end of the motor; a first driving straight gear is installed at the lower end of the output shaft; a transmission device is installed on the outer side of the first driving straight gear; a reduction gearbox is installed at the lower middle part of the output shaft; an intermittent reciprocating motion device is installed at the upper middle part of the output shaft; a drillbit is installed at the other end of the intermittent reciprocating motion device; and a rod piece pushing device is installed at the upper part of the output shaft. Through arrangement of the transmission device, the intermittent reciprocating motion device, the drill bit, the rod piece pushing device, a discharging frame and a feeding frame, when the punching device is used for punching the steel structure rod pieces, all that is required is to lay the steel structure rod pieces in the feeding frame, the motor is started, under cooperation of the transmission device, the intermittent reciprocating motion device and the rod piece pushing device, the steel structure rod pieces are automatically punched and are discharged from the discharging frame, manual installation and fixation are notrequired, automatic batch punching is achieved, and it is guaranteed that the project progress is not affected by punching.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a device for punching holes in steel structure rods for building. Background technique [0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. Chemical, washing and drying, galvanizing and other rust removal and antirust processes. Welds, bolts or rivets are usually used to connect the components or parts. Because of their light weight and easy construction, they are widely used in large factories, venues and superstructures. In high-rise and other fields, when drilling steel pipes or steel columns, we will use drilling devices. However, the existing drilling devices have a cumbersome positioning structure for steel pipes, so that users need to spend a lot of time when positioning steel pipes.

[0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. Chemical, washing and drying, galvanizing and other rust removal and antirust processes. Welds, bolts or rivets are usually used to connect the components or parts. Because of their light weight and easy construction, they are widely used in large factories, venues and superstructures. In high-rise and other fields, when drilling steel pipes or steel columns, we will use drilling devices. However, the existing drilling devices have a cumbersome positioning structure for steel pipes, so that users need to spend a lot of time when positioning steel pipes. For a long time, it affects the drilling efficiency of steel pipes, which brings inconvenience to users, and can no longer meet the needs of users. Therefore, we propose a drilling device for steel structures.

[0003] After retrieval, Chinese Patent No. is CN210388408U patent, discloses a kind of perforating device for steel structure, comprises base, and the middle position of described base top is fixedly connected with workbench, and described base top is positioned by both sides. A bracket is fixedly connected, the top of the bracket is fixedly connected with a beam, the middle position of the bottom of the beam is fixedly connected with a lifting column, the bottom of the lifting column is fixedly connected with a drill bit, and the front and rear two sides of the top of the workbench are fixedly connected. The end positions are fixedly connected with frame blocks, and the positions on both sides of the front and rear ends of the workbench are fixedly connected with fixed rods. The steel structure uses a punching device, through electric cylinders, pull rods, double-sided gear rods, first movable rods, The coordinated use of the second movable rod, arc-shaped tooth plate, hinged rod and clamping block makes it easy to locate, thereby reducing the time spent by the user on positioning the steel pipe or steel column and improving the drilling efficiency , which improves the practicability of the device, but when using steel bars for building construction, a large number of perforated steel bars are required, the device cannot quickly perform batch drilling, and requires frequent installation and disassembly, which affects the progress of the project
