Embodiment Construction

[0018] The present invention will be further explained by specific examples below.

[0019] Such as figure 1 As shown, a portable concrete drilling machine includes a body frame, a motor is provided inside the body frame, a reduction box is provided on the top of the motor, and the reduction box is connected to the diamond drill bit in a threaded manner through a connecting body . At the beginning of the operation, a screw needs to be embedded in the drilling position, and the support rod is screwed to the screw. The function of the support rod is to realize the positioning of the drilling center and support most of the weight of the drilling machine. Then the drill The hole machine is connected to the support bar through the connecting body. When working, the motor rotates to drive the connecting body to rotate, thereby driving the diamond bit to rotate to complete the rotary cutting movement. The ball screw system is connected to the diamond bit through the connecting body...

Abstract

The invention relates to a portable concrete drilling machine. The portable concrete drilling machine comprises a machine body frame (1) and is characterized in that a motor (2) is arranged in the lower portion of the machine body frame (1); the shaft end of the motor (2) is connected to the input end of a reduction gearbox (3) through a coupler; the output end of the reduction gearbox (3) is connected to the right end of a connector device (4) through a key; the upper end of the connector device (4) is fixedly connected with a diamond drill bit (5) in a threaded connection mode; and a ball screw system (6) penetrates through the connector device (4) to be fixedly connected with the diamond drill bit (5). The portable concrete drilling machine has the advantages that the size is small, theweight is low, operation is easy, working flexibility is high in a small space, a drilled hole is smooth, and the drilling efficiency is high.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a portable concrete drilling machine, which belongs to the technical field of drilling. Background technique [0002] In recent years, as an important means of static cutting and demolition of concrete structures, concrete drilling machines have been widely used in the structural transformation of industrial and civil buildings, and have also broadened new ideas for the development of prospecting engineering technology. In the 1980s, the Beijing Mineral Prospecting Engineering Research Institute developed a diamond thin-wall drilling rig, and developed from building drilling to the structural transformation of concrete wall cutting and opening. In the middle and late 1990s, due to the adjustment of the internal layout of the building structure, there was an increasing demand for structural renovation and reinforcement, and the drilling and cutting technology also developed faster. In the la...
