A cpneumatic crawler drilling rig is a light-duty deep-hole drilling rig that uses compressed air as power and is equipped with a crawler walking structure. Pneumatic crawler drill is mainly composed of track assembly, chassis assembly, drive assembly, fuel tank assembly, control assembly, column assembly, main engine assembly, hose assembly and other parts. It has the advantages of 360 ° horizontal angle drilling and so on. Crawler pneumatic drilling rigs can drill holes for water discharge, gas drainage, pressure relief holes in the bottom plate, slit holes in the roof, geological exploration holes, and mine blast holes. It saves time and effort and works efficiently.
JK Drilling are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
The drilling operation and walking of the crawler pneumatic drill rig are controlled by an independent console. For drilling operations, you must first stabilize the drilling rig and turn the start-stop button of the drilling rig console to the stop position, and then move the back-end ball valve on the pumping station to get the air source for the drilling rig's pneumatic console.
As one of our most popular types of drilling equipment, it is very convenient to use. There are two reversing valves on the console to control the rotation and advance as well as retreat of the drilling rig respectively. There is also a ball valve to control the amount of water in the punching process. The right control valve controls the rotation of the rig. Push it forward, the host will rotate forward; pull it backward, the host will reverse; and push it to the middle position, the host will stop. The left control valve controls the forward and backward of the gyrator. When pushing it forward, the gyrator advances; when pulling it backward, the gyrator retreats; and when pushing it to the middle position, the gyrator stops.
The pneumatic crawler drill can be used when connected to the high-pressure tuyere. No motor and no electricity is required, so there is no risk of explosion and the safety parameter is high. The pneumatic crawler drill can work across belts and scrapers. It is suitable for perforation and blasting in mines, earth and rock engineering, severe cold areas, extreme areas, and high-altitude areas. It can also be used to drill and guide detection holes in tunnels and mines.
Most people know the basics of drilling ' there's a drill bit that rotates while moving through a surface to create a cylindrical hole. The range of drilling rig uses is extensive, and this article on what drilling rigs are used for provides a few applications. However, this article will focus on a few of the standard parts of a drilling rig ' each serving a specific purpose that, when combined, facilitate successful exploratory drilling'

Usually the first component of the drilling rig people notice, the mast is a tall fabricated structure towering above all the other drilling components. The mast is vitally important, as it supports the components of the drilling mechanism hovering above the point where drilling will take place.
The drilling line, essentially a thick metal cable, is threaded through the crown block (at the top of the mast) and travelling blocks (suspended above the top drive) and is responsible for raising and lowering the drill string.
The top drive is a rotational motor suspended between the travelling blocks and the drill pipe. The top drive replaced the rotary table (which turns the drill string during drilling) and it lessens the manual labour involved in the industrial drilling process.
The drill pipe is a cylindrical casing that houses the drill string. Drill pipes facilitate wellbore drilling, revolving the drill bit and circulating the drilling fluid as the drilling process is occurring. Drill pipes are also used to extract samples from the earth.
The typical drill bit used in industrial drilling is specially designed to break or crush rock and other subterranean materials as it moves further and further underground. This is found rotating at the end of the drill string and is the part that performs the actual drilling.
Two thirds of the way up the mast is a small platform known as the monkey board. Here, a person known as the 'derrick man' is responsible for assisting with the pipe replacement procedure on drilling rigs that don't feature hands-free rod handlers.
The catline boom is often a metal arm protruding from the mast with a drilling line attached. The catline boom is used to lift heavy equipment from the ground to where it is needed along the drilling process. This is done mechanically and is often used to lift drill pipes.
