[0002] A rotary drilling rig is a kind of engineering machinery suitable for drilling holes in construction foundation projects. It is widely used in municipal construction, highway bridges, high-rise buildings and other foundation construction projects. It is matched with different drilling tools and is suitable for dry (short spiral) or wet (rotary bucket) and rock formation (core drill) drilling operations. Compared with traditional rotary drilling rigs, extended-range rotary drilling rigs mainly replace the traditional engine power system with a range extender, and at the same time increase the main pump motor, winch motor and power head motor. In addition, it is also necessary to increase the power battery and the supporting electronic control system.

[0003] In the prior art, the counterweight of an extended-range rotary drilling rig is generally formed by filling a filler inside a large shell. This method greatly wastes the layout space of the entire machine, especially on a model such as an extended-range rotary drilling rig where space layout is more difficult. The existing counterweight design is difficult to arrange. In summary, there is an urgent need for an extended-range rotary drilling rig and a counterweight arrangement module thereof.
