Rotary drilling rigThe development prospect of this industry is very good, because it brings more benefits to the enterprise when it is used, so it is favored by customers. In order to make everyone more familiar with it, understand its daily use, and better The benefits brought to the enterprise, let's talk about andRotary drilling rigThe working principle of the small knowledge points, hoping to bring help to more people, let it bring more benefits.

During the drilling process of rotary drilling rig, the drilling tool is correctly positioned to the pile position through the walking function of the drilling rig itself and the mast luffing mechanism. The drilling rod is lowered by the mast and the bottom is guided by the valve. The cylindrical drill bit is placed in the hole position, the drilling rig power head device provides torque for the drill pipe, the pressurizing device transmits the pressure to the drill pipe bit through the pressurizing power head, the drill bit rotates to break the rock and soil, the drill bit is directly inserted into the drill bit, and then the drill bit is lifted out of the hole through the drilling rig lifting device and the telescopic drill pipe to unload the soil. In this way, continuously borrow and unload soil, and drill straight to the design depth. At present, the working principle of rotary drilling rig mostly adopts the form of connecting drill pipe and slag hopper. Mud circulation is often used during drilling. Mud plays the role of lubricating, supporting, replacing and carrying drilling slag for such drilling rigs.

With the increasingly stringent environmental requirements of urban construction, traditional drilling rigs are facing a greater crisis. The rotary drilling rig adopts the form of power head. The working principle of the rotary drilling rig is to use a short screw bit or a rotary bucket to directly excavate the soil or gravel and other drilling slag with strong torque, and then quickly take it out of the hole. In the case of support, dry construction can be realized. Even in the special formation that needs mud wall protection, the mud only plays a supporting role, and the drilling mud content is quite low, which greatly reduces the pollution source, thereby reducing the construction cost and improving the construction environment. The hole forming efficiency is high. This is the rotary drilling rig has good environmental protection.

The mechanical devices of rotary drilling rig mainly include luffing mechanism, mast, main and auxiliary winch, power head, follower, booster device, drill pipe, drilling tool, etc., using parallelogram luffing mechanism.,Self-elevating and folding masts; Automatic control of host power detection, rotary positioning and safety protection; Automatic detection and adjustment of drill pipe verticality; New technologies such as drilling depth presetting and monitoring. The color display directly displays the working status parameters, and the whole machine operation adopts pilot control and load sensing,MoreMaximize the convenience, sensitivity, safety and comfort of operation, and fully realize the integration of man and machine. Mechanical, hydraulic and electric.

The content of the above article is the basic information of the rotary drilling rig manufacturer about the product for you. I don't know if you understand it. If you don't know, read it quickly. Well, that's all for today's knowledge. I hope I can help you.
