Boring machine cutter: a rotary cutter that is capable of cutting rock and allowing the shield to advance;

Rock Tunneling Boring Machine shield: In the rock, the shield can protect the safety of the construction personnel and machinery in the tunnel, and help to support the tunnel.

Check the picks on the cutting head for missing and damaged. If necessary, it should be added or replaced in time. Check if the pick rotates in the adapter. When replacing, lock the emergency stop button. Move the power to the stop position to prevent accidental operation and injury. The picks should rotate freely in the tooth holder to prevent grinding deviation. The different types of shields are adapted to the different stratigraphic scopes. The general principle of shield selection is adaptability to ensure reliable, economical and rapid construction of the shield method.

The method of judging the internal drive shaft break of the track reducer or the planetary mechanism gear and bearing damage is to disassemble the track motor and judge the running performance of the motor. If the motor is intact, the internal fault of the track reducer is explained.

Or if it is found that there is obvious noise inside the reducer after the motor is running, and the sound is not uniform, it can be concluded that it is a malfunction inside the track reducer. The method of treatment is to change the track reducer; if the shaft of the reducer is damaged, the simple method is to replace only one axis of the reducer.

The phenomenon that the track shoes or the roller are filled with sand and hardened will cause the load on the track to increase and the track to operate abnormally. The treatment method is to remove the sand and gravel in the track shoe or the roller, so that the track chain can run freely.

The cutting head should be flexible and free from cracks or open welds. The pick seat is seriously worn, affecting its strength or excessive deformation of the inner hole, which should be replaced when it is used. Do not damage other parts of the cutting body during the replacement process. For cabinets with stricter coaxiality requirements, the sleeves should be tightened step by step in the diagonal order. The important bolts should be operated by torque wrench according to the design requirements.
