Abstract

The invention provides intelligent high-precision punching equipment for subway construction. The intelligent high-precision punching equipment comprises a shell and a power device arranged in the shell. A driving sleeve is rotationally arranged in the shell and is in power connection with the power device. A spiral groove is formed in the inner wall of the driving sleeve. A transmission rod penetrates through the driving sleeve, and the transmission rod is provided with a first protrusion matched with the spiral groove. The transmission rod is provided with a first stopping protrusion. A first elastic piece is arranged between the first stopping protrusion and the driving sleeve. A clamping head used for fixing a drill bit is arranged at the lower end of the transmission rod. The intelligent high-precision punching equipment for subway construction is used for solving the technical problem that a hole wall is damaged after the drill bit cracks.

Description

technical field [0001] The invention relates to intelligent high-precision drilling equipment for subway construction. Background technique [0002] Anchor is the most basic part of roadway support in contemporary coal mines and tunnels. It strengthens the surrounding rock of the roadway so that the surrounding rock supports itself. Now anchor rods are not only used in mines, but also in engineering technology for main body reinforcement of slopes, tunnels and dams. [0003] During subway construction, the construction process of anchors includes drilling, that is, pre-drilling is required before installing the anchors, and the accuracy of drilling is directly related to the firmness of the installation of the anchors. The existing drilling construction uses an electric drill to directly drill holes. If the drill bit is stuck in the drilling hole, the drill bit cannot be lifted actively, which makes the bit stuck more seriously, and even causes the drill bit to crack. The c...
