Anchor Drilling machine possible breakthroughs and improvements in the future
writer:ld-driller | time:2020-09-03 16:07:35

So far, the anchoring hole drilling equipment has been greatly improved. With the continuous development of technology and the difference of engineering requirements, the improvement has to continue to be improved in the following aspects:

The optimization of structural parameters and the application of high-tech new materials improve the performance of monomer anchor drilling machine and reduce the weight. The adoption of high-tech rock drill will expand the application scope of rotary drilling mode. The application of high-tech microelectronics technology in different power and different types of anchor drilling machine may cause some fundamental changes to the anchor drilling machine, such as changing the characteristics of the drilling machine.

Improve operation performance and reliability. Foreign countries have discussed the comprehensive automation equipment of computer-controlled bolt hole drilling and bolt installation. The successful application of rock drilling robot will surely strongly promote the progress of bolt hole drilling equipment.

The development of bolt hole drilling equipment is based on the development of Bolt support technology and rock drilling technology. The emergence of new types of Bolt support and new materials will affect the structural parameters of Bolt drilling machine, new requirements for technical performance and function. The development of anchor drilling machine must follow the technical development of Bolt support. Meanwhile, the development of rock drilling technology will promote the improvement of bolt hole drilling equipment. The research results of different rock drilling methods and general rock drilling tools will be timely transplanted to the development of bolt hole drilling equipment.

Our factory will also keep pace with the times and produce the best anchor drilling machine.
