Performance of operation regulations on drill pipe
A drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the drilling. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand large torques, twists, bends and vibrations during rotation. During the drilling process, the drill pipe can be used multiple times. The operation procedures for drill pipes are as follows: 1. Hole position. Do not form the operation of the drill pipe, but be careful not to "don't" the drill pipe. 2. Release the drill. Under the action of the gravity of the drill pipe and the drilling tool, the friction force of the hole wall and the mud are overcome.

What is the skid during the construction of the rotary excavator?
In the practical application of rotary excavators, there are many problems in the use of rotary excavators due to various external factors, thus affecting the normal construction. Today, the editor will briefly introduce the common causes of slippage in the daily use of rotary excavators, hoping to provide you with help. Causes of skidding in the construction of rotary digging machine: the drilling tool is not concentric with the drill pipe of rotary digging machine, the angle of drilling teeth is less than 45 degrees, the center cone is improper, the teeth are arranged too densely, the drilling tool is seriously worn, and a series of reasons cause skidding. The reason for the mud is that the construction on the sub-clay bottom layer often slips, which is mainly due to the repeated use of the mud.

About the installation and removal of the drill bit
The drill bit looks small, but its installation and use are still very exquisite. Familiar with it all know. Let's see what it's worth. First is the installation of the drill bit. Slowly lift the drill box, put the four legs of the drill box into the four holes of the drill rotary table, select the corresponding drill box core plate according to the specifications of the drill bit, lift the drill box core plate into the drill box, and then put the drill groove to be installed into the drill box corresponding to the convex point of the drill box core plate. Put the drill into the drill box, and the drill bit will be stuck in the rotary table core. Then screw the drill pipe with the connecting nut of the drill bit in turn. Again, the drill bit is disassembled. Lifting drill pipe (Attached

Factors Affecting Selection of Rotary Digger Bit
The rotary drill bit is the main component of the rotary drilling rig, which determines the thickness of the rotary digging bottom layer. At the same time, the construction requirements are different, which will eventually affect the progress of the construction, so it is very important to choose the drill bit of the rotary excavator. Let's look at the factors that affect the rotary drill bit. Geology is diverse, which determines the type of rotary drill bit. In the pebble drilling special drilling pebble rotary drill bit, so according to your drilling geology to distinguish. Helps you complete construction tasks quickly. Another point is that different rotary drilling rigs have different rotary drilling bits installed, which is also one of the influencing elements. Like surface soil, muddy sub-clay, clay layer in dry state

Different usage of different drill bits
Drill bits are often seen in our lives and work, but all kinds of drill bits, will we distinguish their usage? Drill bits are classified according to cutting principles and can be divided into cutting drills, impact crushing and shearing drills, and grinding drills. According to the function classification, it can be divided into comprehensive drilling bit, ring drilling bit and special bit. Different drill bits, their range of use is also different. For example, drag bits are used for soft and plastic rocks with large torque, bad drilling tools and no moving parts. Cone bit is widely used in soft and hard formations, with small torque and cone rotation. Diamond drill bits for hard, highly abrasive formations, no activity

Structure of Triangular Drill Rod
The structure of the triangular drill rod The triangular drill rod assembly is composed of triangular drill rod, guide frame, lifter and other components (some triangular drill rod assemblies also include casing). According to the pressure method and structural characteristics of the triangular drill pipe, the triangular drill pipe can be divided into the following types: 1. Friction type triangular drill pipe Each section of triangular drill pipe is composed of seamless steel pipe and the driving key welded on it. There are two types of external drive keys, three-key and six-key, and there is no pressure lock at the center of the external drive key. The downward pressure is the downward friction force between the gravity of each section of the triangular drill pipe and the table-in-table key during drilling. 2. Machine lock type triangular drill pipe Each section of triangular drill pipe is made of seamless steel pipe

What are the maintenance and maintenance of hydraulic tunnel drilling rig for coal mine?
Maintenance and maintenance methods of hydraulic tunnel drilling rig for coal mine: 1. Hydraulic oil with specified label should be used, and the filter screen of air filter must be used to add hydraulic oil. 2. Always observe the fuel tank level and oil quality during use. If it is insufficient, add oil in time. If the oil is unqualified, drain the oil and clean the fuel tank. Then add clean special oil through the air filter screen. Clean the hydraulic system completely. 3, often check and clean the jack and the screw rod, and coated with butter, the surface of the fuselage guide should be often added with lubricating oil. 4. Always flush the gap between the chuck and the gripper slips with high-pressure water to remove rock powder. 5. Inspection

How to solve the failure in the construction of rotary drilling rig
Rotary drilling rig is an indispensable construction equipment for building engineering into a hole, which can be used for sand, clay, silty soil and other soil construction, and is widely used in continuous, foundation reinforcement and multiple foundation construction. However, any product will be abnormal in use. Today, Xiao Bian is talking about the failure of machinery in construction. Common faults in the construction of rotary drilling rig: 1. During the perfusion process, if it is found that the mud level in the borehole casing suddenly rises and overflows the casing, then drops suddenly and bubbles appear, it should be suspected that it is a sign of hole collapse and can be detected by a sounding hammer. If the sounding hammer was originally suspended on the concrete surface and has not been taken out, it is buried and cannot be lifted up, or the sounding hammer is used for sounding

Classification and Comparison of Advantages and Disadvantages of Double-tube Diamond Bits
Although the diamond bit in the drilling industry is the most widely used, but the double tube diamond bit also plays an important role, especially in deep hole and super deep hole drilling, the application of the double tube bit is much higher than the single tube. In the actual drilling operation, the double-tube drill bit often uses the double-tube drilling tool, and its main advantage is that it does not need to frequently carry out the drilling and pouring out the core, and the core can be quickly lifted out of the hole by the lifting mechanism of the drilling tool, and the process does not affect the normal drilling. The above introduces the classification and comparison of advantages and disadvantages of single-tube diamond drill bits. In this article, the gold drill bit factory will mainly introduce the classification and advantages and disadvantages of double-tube drill bits. 1. double-tube diamond
