Safety Operation Regulations for Impact Drill
The percussion drilling machine is an important drilling machine for the construction of cast-in-place pile foundation, which can adapt to various geological conditions, especially in the pebble layer, and the percussion drilling machine is more adaptable than other types of drilling machines. At the same time, with the impact drill hole, into the hole, the hole wall around the formation of a layer of dense soil layer, to stabilize the hole wall, improve the pile bearing capacity, have a certain role. Installation of 1. drilling rig 1. The site where the drilling rig is installed shall be flat and solid. If the drilling rig is installed in the soft stratum, the foundation shall be treated, and then sleepers shall be paved to ensure the stability of the drilling rig during operation, so as to avoid local subsidence of the drilling rig during drilling and affect the drilling.

Steps and process of drilling construction
Drilling engineering is a process of crushing rocks in the earth's crust according to a certain process with certain tools. The result of this project is drilling holes in the earth's crust. A borehole is a space of circular cross-section excavated from the surface like rock, generally of small diameter and great depth. The diameter of 25-500mm is called drilling; the diameter of 500mm or more is called drilling. The depth of drilling has been from several centimeters to several kilometers, and the current drilling depth has exceeded 10000 meters. The borehole includes an orifice, a hole bottom, and a hole wall. The orifice is the opening part of the borehole, that is, the place where the borehole intersects the ground or tunnel; the bottom of the hole is the deepest part of the borehole;

Yi Kuang Science and Technology | Teachers' Day | Don't Forget Teacher's En in September
Autumn September is another year of Teachers' Day. Looking back on the past, do you still remember the teachers who are persuasive beside you? They are so lovely that it is their teaching and severity that made us who we are today. Thank you for accommodating all our rebellious patience and teaching our teachers in the best years. It is because of your teaching that our life has a triumphant return.

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

Rig operation: operation skill mainly lies in pressurization
From the outside, the rotary drilling rig gives the feeling of being very tall, and it feels like the handle after entering the cab. There are many buttons, which generally gives people a complicated feeling. However, the fact is also true. From the positioning of the machine to the auxiliary working condition, and then to the drilling under the main working condition, there are indeed many actions required. However, in order to open the rotary drilling rig well, pressure is the most important among the many operating actions! The pressurization we mentioned here is not blindly downward pressurization through the handle, but to control the pressurization intensity and pressurization time for different rock and soil bottom layers. The routine is as follows: lifting suspension point floating long floating point pressurization short stroke pressurization long stroke

What are the basic components of a rig and what do they do?
The drilling rig is mainly composed of four major parts: rotary mechanism, feed mechanism, lifting mechanism and frame. The rotary drilling tool drives the drill bit to work at the bottom of the hole. Feeder mechanism: adjust the drilling pressure required for the drill bit to work at the bottom of the hole and control the feed speed; Lifting mechanism: used to complete the lifting of drilling tools, casing and ancillary work. Some drilling rigs also use the lifting mechanism to control the feed speed and feed pressure. Frame: according to the characteristics of the overall layout of the drilling rig, the above components are assembled into one or two whole, to achieve the requirements of compact structure, easy installation and disassembly.

Drill pipe is made of drill pipe body and joint by friction welding
Oil drilling drill pipe is made by friction welding of drill pipe body and joints. On the basis of ensuring that the microstructure and mechanical properties of drill pipe body and joint meet the requirements of technical standards, the microstructure and mechanical properties of friction welding weld and heat affected zone become the key to the quality control of drill pipe. The mechanical properties of friction welding weld and heat affected zone are determined by its organization. Therefore, it is of great significance to study the microstructure characteristics of friction welding weld and heat affected zone of drill pipe and its influence on mechanical properties to ensure and improve the quality of drill pipe. Drill pipe friction welding is a kind of solid phase welding. For a long time, people have been interested in melting welding welds and heat.

Basic knowledge of hydraulic transmission of full hydraulic drilling rig
Full hydraulic drilling rig is mainly composed of three parts, the power source of the host; the working mechanism is to complete the required action; the role of energy and control. That is, the prime mover, the transmission device and the working mechanism. The prime mover is a machine transmission device set between the prime mover and the working mechanism. There are many types of transmission devices. According to the different parts or working media used in the transmission, they can be divided into: mechanical transmission, electric transmission, and pneumatic transmission. And liquid transmission. Liquid transmission is a transmission mode that transmits energy and controls by liquid working medium. According to its working principle, it is divided into hydraulic transmission and hydraulic transmission. Hydraulic transmission is mainly benefit

What are the characteristics of small rotary drilling rig?
At present, the rotary digging machine market, the most popular is the small rotary drilling rig, favored by the public, why small rotary drilling rig so popular. Features of small rotary drilling rigs: 1. High efficiency of small rotary drilling rigs: advanced technology of small rotary drilling rigs, circular drilling, will not increase the load of the machine with the increase of depth, and the operation is very stable, at the same time, the torque is large and the efficiency is also high. 2, small rotary drilling rig to adapt to a variety of topography, to adapt to a variety of geological conditions, to adapt to a variety of construction requirements. The body design is compact, the operation is flexible and rapid, and the transition is convenient.
