Abstract

The invention discloses an underwater drilling tool attitude detection system, which comprises a tunneling mechanism, a power lift mechanism and an operation control system. The power lift mechanism is arranged on the ground and used for lifting the tunneling mechanism, and the operation control system is used for controlling operation of each mechanism. The tunneling mechanism comprises a tunneling frame, the outer end of the tunneling frame is in slide guide fit with a slide groove type anti-torque device fixedly mounted on the vertical shaft wall, a main driving device is mounted in the middle of the tunneling frame and connected to a drilling arm below the tunneling frame, and at least two auxiliary driving devices mounted on the drilling arm are connected with a drilling tool below the drilling arm. Two tilt angle sensors are horizontally mounted on the tunneling frame, a plurality of first position sensors are uniformly distributed on the drilling arm, a plurality of second position sensors are uniformly distributed on the drilling tool, and the tilt angle sensors, the first position sensors and the second position sensors are all connected with the operation control system.The underwater drilling tool attitude detection system is high in sensitivity, low in power loss and great in anti-interference performance and well meets onsite utilization requirements.

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...
