Abstract

The present invention proposes an intelligent and high-precision drilling equipment for subway construction, which includes a housing and a power device installed in the housing. A drive sleeve is rotated inside the housing, and the drive sleeve is connected to the power device by power. The inner wall of the drive sleeve is provided with a spiral groove, the drive sleeve is pierced with a transmission rod, the transmission rod is provided with a first protrusion matching the spiral groove, and the transmission rod is provided with a first stop protrusion A first elastic member is provided between the first stop protrusion and the driving sleeve, and a clamping head for fixing the drill bit is provided at the lower end of the transmission rod to solve the technical problem of damaging the hole wall after the drill bit breaks.

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...
