In the use of rotary digging machine drill pipe, many times, users will encounter the phenomenon of sticking, causing rotary digging machine drill pipe sticking there are many reasons, in order to reduce the loss of rotary digging machine drill pipe sticking, do a good job of prevention is very important. Here, Xiaobian will tell you how to prevent the drill pipe of rotary digging machine from sticking. 1, to the drilling bucket for regular maintenance and maintenance. Because the gap between the bottom of the bucket and the hook increases, the weight of the bottom of the bucket is carried by the bottom of the hole after drilling, which easily leads to the hook being pushed away or shaken open by the muck. 2. When the drill pipe of the rotary excavator is drilling into a large layer with large vibration, it is best to adopt a low-speed and light-pressure method to reduce the vibration. However, if you drill into a hard formation, you should inject
In the use of rotary digging machine drill pipe, many times, users will encounter the phenomenon of sticking, causing rotary digging machine drill pipe sticking there are many reasons, in order to reduce the loss of rotary digging machine drill pipe sticking, do a good job of prevention is very important. Here, Xiaobian will tell you how to prevent the drill pipe of rotary digging machine from sticking.
1, to the drilling bucket for regular maintenance and maintenance. Because the gap between the bottom of the bucket and the hook increases, the weight of the bottom of the bucket is carried by the bottom of the hole after drilling, which easily leads to the hook being pushed away or shaken open by the muck.
2. When the drill pipe of the rotary excavator is drilling into a large vibration layer, it is best to adopt a low-speed and light-pressure method to reduce the vibration; and if drilling into a hard formation, pay attention to the wear of the drilling bucket and replace the edge teeth in time., So as not to cause shrinkage.
3. When lifting the main roll, because the load can change the sound of the main roll, the lifting speed will slow down, and the mast will sink when the load increases. By listening and watching, you can know the load change in the first time and change the operation in time.
4. If the lifting load increases, the lifting main roll should be slowed down or stopped. The depth and geological conditions of the drilling bucket can be known through the depth meter display. At the same time, the drill pipe can be rotated at low speed to see if there is any load, so as to know whether the bottom of the bucket is open.
5. After closing the bucket bottom, use the main roll to move or rotate the impact drill bucket left and right. If the bucket door can be vibrated frequently, it means that the hook is not firm. The reason should be found out and repaired in time to prevent the bucket bottom from being vibrated when drilling into the ground with large vibration.
