Problems solved by technology

In the current vertical underground space construction, the traditional shaft drilling rig uses a full-section cutter head for construction. The cutter head has a complex structure and heavy weight. Excavating the trajectory consumes a lot of manpower, material and financial resources, but the final effect is not ideal

Abstract

The invention discloses an underwater drilling tool attitude detection system. The system comprises a tunneling mechanism, a power lift mechanism arranged on the ground and used for lifting and releasing the tunneling mechanism and an operation control system used for controlling operation of the mechanisms, wherein the tunneling mechanism comprises a tunneling rack, the outer end part of the tunneling rack is in sliding pilot fit with a chute type anti-torque device fixedly mounted on the wall of a vertical shaft, a main drive device is mounted in the middle of the tunneling rack and connected onto a drill boom located below the tunneling rack, and at least two auxiliary drive devices mounted on the drill boom are connected with a drilling tool located below the drill boom; two tilt anglesensors are horizontally mounted on the tunneling rack, a plurality of first position sensors are uniformly distributed on the drill boom, a plurality of second position sensors are uniformly distributed on the drill boom, and the tilt angle sensors, the first position sensors and the second position sensors are connected with the operation control system. The underwater drilling tool attitude detection system is high in sensitivity, quite low in power loss and high in anti-interference performance and can meet the requirement of field service.

Description

technical field [0001] The invention relates to the technical field of shaft excavation construction machinery and equipment, in particular to an underwater drilling tool posture detection system. Background technique [0002] With the development of the national economy, the construction of urban rail transit and the construction of urban underground pipe corridors have developed rapidly in recent years. In the construction of underground projects, such as shield starting and receiving shafts, mining shafts, tunnel ventilation shafts, underground fortification shafts, underground parking lots, mine roadways, traffic tunnels and other underground engineering constructions, in order to ensure the smooth progress of construction, excavation tools are required. Shafts for transporting materials and ventilation. The upper end of the shaft is connected to the ground, and the lower end of the shaft is connected to the roadway or tunnel. Shaft excavation is the construction proce...
