Description

technical field [0001] The invention relates to a control system of a drilling rig, in particular to a special control system for a down-the-hole drilling rig. Background technique [0002] Down-the-hole drilling is engineering equipment used to drill holes in rocks. It can be used to drill rock anchor holes, anchor holes, blast holes, grouting holes, etc. in urban buildings, railways, highways, rivers, hydropower and other projects. Drilling construction. With the increasing demand for resources, many mines are in urgent need of the key equipment of the mining process - down-the-hole drilling rigs. At the same time, in order to improve drilling efficiency, thereby shortening the moving time of drilling equipment, increasing the number of drilling holes per unit time, and thereby improving production efficiency, self-propelled down-the-hole drilling rigs have received more and more attention. [0003] At present, there are mainly two driving forms of down-the-hole drilling...

AI Technical Summary

Problems solved by technology

One is to use the form of motor drive, through which the motor is connected to the reducer or the hydraulic system to drive the down-the-hole drill to work; this drive mode is simple to control and stable in work, but it is difficult to realize self-propelled due to the limitation of the power supply device.

Another hydraulic drive system that uses an internal combustion engine to connect the drill bit and the traveling device through the internal combustion engine; this driving method realizes the self-propelled equipment, but due to complex working conditions and frequent changes in the load of the internal combustion engine, the control system is complicated and the stability decreases

At present, the new type of down-the-hole drilling rig uses internal combustion engine to generate electricity, and then uses electric power to drive the drill bit and traveling device. This driving form has the advantages of the above two driving forms, but it puts forward higher requirements for the control system.
