The Application of Limit Switches And Travel Switches in Rotary Drilling RIGS

Rotary drilling RIGS play a crucial role in construction, and their safe and efficient operation cannot do without various key components. Although limit switches and travel switches are small, they play an irreplaceable role in ensuring the normal operation of rotary drilling RIGS. Now let me tell you about their specific applications in rotary drilling RIGS.

1. Preventing excessive lifting of the drill pipe: The limit switch is installed on the drill pipe lifting device. When the drill pipe is lifted to the preset limit height, it will quickly sense and trigger a power-off, preventing the drill pipe from continuing to rise and avoiding damage caused by excessive lifting due to collision with other components.

2. Control the descent depth of the drill bit: Set the maximum descent depth of the drill bit through the limit switch. When the drill bit touches this position, the limit switch feeds back a signal to stop the drilling rig from descending, ensuring that the drilling depth meets the construction design requirements and avoiding over-deep drilling.

3. Protect the rotary mechanism: Install limit switches at the boundary of the rotation range of the rotary mechanism of the rotary drilling rig. When the rotation Angle reaches the limit value, the switch will act to promptly brake the rotary device to prevent excessive rotation from causing distortion or breakage of the equipment connection parts.

4. Monitoring the verticality of the mast: The travel switch, in conjunction with the mast verticality monitoring system, will send a signal when the mast's tilt Angle exceeds the safe range, reminding the operator to adjust the mast to ensure the stable operation of the drilling rig and prevent overturning accidents.

5. Ensure the safety of track movement: Limit switches are set at both ends of the track movement path of the crawler rotary drilling rig. When the track approaches the preset movement boundary, the switch triggers an alarm and restricts the track from continuing to move, preventing the drilling rig from sliding out of the safe operation area.

6. Maintain the operation of the power head: The limit switch monitors the rotation of the power head in real time. Once the speed of the power head is abnormal or reaches the set limit operating time, it will immediately cut off the power to prevent the power head from malfunctioning due to overheating, excessive wear, etc.

In conclusion, limit switches and travel switches are like the "safety guards" of rotary drilling RIGS, ensuring the stable operation and construction safety of the RIGS from multiple dimensions. They each perform their own duties and cooperate with each other, which not only improves the accuracy of construction, but also effectively reduces the probability of equipment failure and safety accidents.
