Abstract

The invention discloses a building steel beam drilling device, and relates to the technical field of building steel beams. In order to solve the problem of drilling position adjusting, the building steel beam drilling device specifically comprises a drilling box, the top of the drilling box is fixedly connected with an air pump and a first air cylinder, one end of the drilling box is provided with an observation window and a handle, the inner wall of the bottom of the drilling box is provided with a fixing assembly, one end of the first air cylinder is fixedly connected with a fixing block, and one end of the fixing block is fixedly connected with a drilling assembly; and the fixing assembly comprises a moving plate and a first hydraulic rod, and a first sliding block is fixedly connected to the bottom of the moving plate. According to the building steel beam drilling device, by arranging the moving plate, after a steel beam body is fixed, the first hydraulic rod is started, and the whole fixing assembly can move horizontally, so that the drilling position can be adjusted, and the position of the steel beam body on the fixing assembly does not need to be adjusted; and meanwhile, a toothed bar is rotated through a rotating rod, a first fixing plate and a second fixing plate can move relatively, adjustment is conducted according to the length of the steel beam body, and the steel beam body is clamped.

Description

technical field

[0001] The invention relates to the technical field of building steel beams, in particular to a drilling device for building steel beams. Background technique

[0002] Steel beam is a common building component made of hot-rolled I-beam or channel steel; before assembly and installation, it is necessary to punch holes in the steel beam; at present, the common punching device is through However, since the shape of the hole on the steel beam is not a simple round hole, but a long strip, it greatly increases the difficulty of manual drilling with an electric drill.

[0003] After retrieval, the Chinese patent application number is 201611070109.8, which discloses a steel plate drilling device, including a frame, a motor, a drill bit and legs; a motor is installed on the motor frame, and a drill bit is fixedly installed on the output shaft of the motor. The lower side of the motor frame is equipped with a laser light through a universal joint; one end of the exhau...
