Generally divided into drilling rigs.
You can refer to the dimensions of the above model. Medium. Small. Type a drilling rig.
The essence of down-the-hole drilling is to make the impactor dive into the hole during drilling, so as to reduce the energy loss caused by the impact work transmitted by the drill pipe, thus reducing the influence of hole depth on drilling efficiency. DTH drilling company's drilling equipment is DTH drilling rig. In China, YQ-80, YQ- 100 and QZ- 165 are commonly used models in underground mines. When the solidity coefficient f=8? Drilling deep holes with a diameter of 80 ~ 165 mm in 14 ore and rock can obtain higher drilling speed.
Domestic DTH drilling rig was first produced in Xuanhua, Hebei Province in 1950s. Through continuous investment and self-development, the performance and technical content of drilling rig have been greatly improved, and it has established a good reputation in the international market. After the 1980s, Fortune 500 companies from the United States, Sweden and other countries came to Xuanhua to invest and set up factories or joint ventures. Its products and production technology are used as university teaching materials for scientific research and teaching. Therefore, DTH drilling rig is synonymous with Xuanhua drilling rig in China. After 1990s, Xuanhua, Hebei Province has formed an equipment production base. Some enterprises mainly develop and produce the latest, high-performance, low-consumption and open-pit drilling rigs, and can also supply accessories. Products are widely used in large, medium and small mines, hydropower, transportation and other earthwork excavation blasting projects, and can also be used for underwater rock perforation blasting in ports and waterways. They have strong technical force, advanced technology, strong manufacturing ability and first-class management level, and have the advantages of professional technicians in new product development. They have cooperated with scientific research institutions all the year round to develop new hydraulic down-the-hole drilling rigs, which have been well received by users.
1997 fully hydraulic open-air DTH drilling rig with auxiliary actions of walking, lifting, steering and positioning. Obtaining the national patent has promoted the rapid development of domestic full-hydraulic open-pit down-the-hole drilling rig. Newly developed DTH hydraulic integration and full hydraulic drilling rig. It is a universal design integrating drilling rig and air compressor, which highlights the characteristics of economy and high performance.
DFYQ DTH all-in-one machine
The biggest feature of DFYZ300 fully hydraulic integrated rock drilling rig is that all actions are hydraulic, which can be separated from the pneumatic link of traditional drilling rig and realize completely independent operation. It is a perfect combination of low consumption and high efficiency. DFYQ3000 Hydraulic Down-the-Hole Integrated Machine is a hydraulic integrated machine with low energy consumption and high efficiency. Integrated design, perfect combination of air compressor and drilling rig to realize independent operation; Energy is fully utilized.
The national production base of DTH drilling rig is located in Xuanhua District, Zhangjiakou City, Hebei Province. At present, there are nearly 300 DTH drilling rig manufacturers, with an annual output value of 654.38+300 million, which has solved the employment of tens of thousands of local people. Small and medium-sized enterprises are catching up, and they are among the best in new product research and development, product output, production efficiency and safety, and 5S management.
Xuanhua drilling rig enterprise pursues the management policy of "science and technology as the guide and quality as the survival" and makes due contributions to the revitalization of national industry.
