What problems should be paid attention to when operating a crawler water well drilling rig?

  With the continuous development of science and technology, machinery and equipment have developed in the direction of automation, and crawler mounted water well drilling rigs are also one of them. In the crawler water well drilling rig industry, the automation degree and remote control technology of crawler water well drilling rigs are getting faster and faster, which is also the general trend of future development. The benefits of automated production of crawler water well drilling rigs are that it improves the production efficiency of crawler water well drilling rigs, effectively reduces production costs, virtually improves product quality, and reduces human operation errors. Take a comprehensive look at crawler water wells. The development of automation of drilling rigs is very necessary and very important.

The automated production of crawler water well drilling rigs is composed of downhole automation and surface automation. The development of surface automation of crawler water well drilling rigs is realized by surface automation equipment, while downhole automation is completed by rotating closed-loop directional drilling system. The two are different. Although the automation development of crawler water well drilling rigs can bring many benefits, we also need to always pay attention to the direction of automation development, let it develop in a more controllable direction, and strive to make the development of crawler water well drilling rig industry more and more it is good. It is announced that the editor will teach you what problems should be paid attention to when operating a crawler water well drilling rig.

1. Crawler-type water well drilling rigs must have received special training, rigorous examinations, and a certain amount of work experience before they can work with a certificate.

2. Crawler water well drilling rig workers must master the operating essentials of the drilling rig and comprehensive maintenance knowledge, and have considerable experience in troubleshooting.

3. When the drilling rig is shipped, safety inspections must be carried out. The parts of the drilling rig must be complete, the cables must be free of electric leakage, drill pipes, drilling tools, and other five damage phenomena;

4. Crawler-type water well drilling rigs should be installed firmly, and bends or ramps should be slowly fixed with steel wires.

5. When entering the construction site, the drilling rig should be fixed, the area of the drilling site should be larger than the rig base, and there should be enough safe space around.

6. When drilling, the construction must be carried out strictly in accordance with the hole position, orientation, angle, and depth of the hole, and the driller cannot change it without authorization;

7. When installing the drill pipe, check the rig to ensure that the drill pipe is not blocked, bent, and the thread is not worn. Unqualified drill pipes are strictly prohibited to use.

8. When loading and unloading the drill bit, strictly prevent the pipe clamp from damaging the cemented carbide sheet, and strictly preventing the flat drill bit and the core tube from being clamped.

Friends with less experience are prone to sticking or breaking the drill pipe. The most direct impact is the economic loss. I hope everyone can gain something after reading it.

What are the operating procedures of DTH drilling rigs?

 The DTH drilling rig is common drilling equipment, mainly composed of a rotating mechanism, lifting mechanism, pushing mechanism, supporting mechanism, and impact mechanism. It has the characteristics of fast drilling speed and convenient operation. The operating rules of the down-the-hole drill are as follows:

(1) Installation and preparation of down-the-hole drill rig

1. After the cave is ready to be drilled, its specifications can be determined according to the drilling method. Generally, when drilling horizontal holes, the height of the cave is 2.6-2.8 meters, and in upward, downward, or inclined holes, the width, and height of the cave are 2.5 meters and 2.8-3 meters, respectively.

2. Gas and water pipes, lighting lines, etc. should be led near the working surface for use.

3. According to the design requirements of the hole, the bracket should be firmly fixed. The upper and lower ends of the support rods should be covered with wooden planks. The horizontal shaft and buckle are mounted on the pillar at a certain height and direction. The manual winch is used to lift the machine and fix it on the pillar according to the required angle, and then adjust the hole direction of the drilling machine.

(2) Check before the operation

1. When starting to work, please carefully check whether the air and water pipes are firmly connected and whether there is air or water leakage.

2. Check whether the oiler is full of oil.

3. Check whether the screws, nuts, connectors, etc. of each part have been tightened and whether the chromatographic column is firmly supported.

(3) Drilling procedure

When opening the hole, please start the motor first and pull the pusher of the robot after the normal transfer. Make it get proper propulsion, and then pull the handle that controls the impactor to the working position. After drilling the hole, you can open the water valve to keep the air-water mixture in an appropriate ratio. Perform regular rock drilling. When pushing the wire stripper to collide with the tool holder, a drill rod will be drilled out. It is necessary to stop the operation of the motor and supply air and water to the impactor, insert the fork into the drill pipe slot of the tool holder, reverse the motor, move the slide plate backward, and disconnect the joint pipe from the drill bit, and then connect the next drill pipe to Work continuously according to this cycle.
