Discussion on safety operation rules of drilling operation vehicle in electrified tunnel?

Everyone attaches great importance to tunnel engineering, and electrified tunnel drilling is widely used. Today, we will learn about the safety operation rules of the electric tunnel drilling operation vehicle.

A, drilling operations, in addition to the driver, co-driver, drilling operation vehicles should also have commanders, according to the location of the drilling to determine the parking place, command drilling operation driver's operation.

Two, the power part should comply with the provisions of the fourth quarter of Chapter III "internal combustion generator set".

Third, the work part.

1. Before operation, check that the flat car floor should be complete to prevent people from falling.

2. When starting the engine, first confirm that the oil control valve at the lower left of the console is in the "oil return" position, and the handles of other valves should be in the middle position.

Before entering the tunnel, both engines should be started and all lights should be turned on.

4. Before the rig works, the commander should direct the rail car driver to brake the vehicle. When the top is against the ceiling, it is forbidden to move the sliding table back and forth.

5. In the process of operation, all actions should be smooth. Do not push or pull the joystick. All actions cannot be completed at one time, and "inching" operation is needed. At the same time, pay attention to monitoring to prevent the tubing from being crushed.

6. After the drill bit touches the hole wall, it should advance and retreat several times, and then drill down to prevent the drill pipe from tilting flat top and drilling deviation, which makes it difficult for the drill pipe to exit.

7. When the drilling rig is in the original position, the compensation cylinder should be pushed forward first, and then the drilling rig can be operated to complete the head-up action. In the process of drilling rig falling, we should also strengthen the observation of the column to prevent the column from being crushed.

8. When the sliding table needs to be moved during the operation, the top and drilling rig should be recovered first.

9. After the operation, when the drilling rigs on the left and right columns fall downward, don't fall to the bottom at once to avoid crushing the tubing. There should be supervision during the operation.

10. When the drill pipe is installed on the drilling rig to "clamp" the drill pipe, be careful not to crush the drill pipe.

1 1. The drilling truck has stopped for several days. When it is used for the first time, it should be tested first. During the test, the action should be slow to prevent damage to the oil cylinder.

12. After the operation, dismantle the drill pipe. In case of strong wind, rain and snow, the rig should be wrapped in clean bags to prevent rain and sediment from invading the rig.

13. When transferring the construction site, all movable parts of the whole vehicle should be put back in their original positions and properly fixed.

I believe that after the above introduction, everyone has a certain understanding of the safety operation procedures of the electric tunnel drilling operation vehicle. Welcome to Zhong Da for more information.
