Abstract

The invention discloses a rotary drilling rig and a counterweight device thereof. The counterweight device comprises at least two counterweight units, and the adjacent counterweight units are detachably connected. In the working process of the rotary drilling rig, the counterweight device matched with the rotary drilling rig is selected according to different properties of the rotary drilling rig.According to the counterweight device, due to the fact that the counterweight units are detachably connected, the counterweight device can be better matched with multiple functions of the rotary drilling rig; and due to the adjustability of the weight of the counterweight, the safety and stability of the whole machine under different working conditions can be better maintained, and therefore theuse stability of the rotary drilling rig is improved.

Description

technical field [0001] The invention relates to the technical field of counterweight design of a rotary drilling rig, in particular to a counterweight device of a rotary drilling rig. The present invention also relates to a rotary drilling machine comprising the above counterweight device. Background technique [0002] The function of the counterweight device of the rotary drilling rig is to balance part of the weight of the drilling rig, so as to maintain the safety and stability requirements of the drilling rig under different conditions. [0003] For the steel plate tailor-welded integral type of the counterweight device, it is made of steel plates of different thicknesses in a certain order. As long as the use requirements are met, the thickness of the steel plates used is relatively random. Heavy usage requirements are sufficient. [0004] In large rotary drilling rigs, steel plate tailor-welded integral counterweights are generally used. Usually according to the wei...
