Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a water-mill drilling rig lifting and transporting vehicle platform. Background Art

[0002] Due to the restrictions of the surrounding environment, more and more tunnel constructions choose to use non-explosive excavation technology. In the excavation process of cross passages and pilot tunnels, water-grinding drills are often used to drill holes and core along the periphery of the face, thereby providing an open surface for subsequent static splitting or static crushing construction and improving the surrounding rock crushing effect.

[0003] The water-mill drill enters the tunnel and reaches the face, where it performs core drilling. During operation, the motor drives the drill bit to rotate through the transmission device, while the grouting system injects cement slurry into the borehole. The water spraying system plays a role in cooling and cleaning, and the coring system can quickly remove the core. The existing water-mill drill lifting platform uses a transport vehicle to carry the drill into the tunnel for work, and the height is fixed after entering the tunnel section, so it is impossible to excavate a higher section. Every time the upper step section is excavated, it is necessary to pile up the waste slag to raise the platform, which is troublesome and dangerous. It is difficult to quickly change the position of the drill, which results in a lot of time spent on transferring the drill to the next hole position, seriously affecting the construction progress. In addition, the water-mill drill frame is often connected with a simple scaffolding during construction, and its stability and safety cannot be guaranteed. Utility Model Content
