Abstract

The invention provides a rotary drilling rig and a damping ring thereof. The damping ring of the rotary drilling rig comprises: an annular main body, wherein the annular main body comprises a plurality of arc-shaped sections, and the arc-shaped sections are connected end to end; and fasteners which are arranged at the joints of the adjacent arc-shaped sections, wherein the multiple arc-shaped sections are connected together through the fasteners. According to the technical scheme, the problem that in the prior art, operation is inconvenient when a damping rubber mat of a rotary drilling rig is replaced is solved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a rotary drilling rig and a damping ring thereof. Background technique [0002] Rotary drilling rigs are commonly used hole-forming construction machinery. Due to different construction conditions, existing rotary drilling rigs usually use a machine-locked drill rod structure in which multi-layer drill rods with adjustable lengths are nested and interlocked with each other. When the drill pipe is working, the gravity of the outer layer rod is transmitted to the shock-absorbing seat through the shock-absorbing spring or the shock-absorbing rubber pad. If the phenomenon of "smashing the rod" occurs, the outer layer rod will hit the shock-absorbing seat under the action of its own weight, and the shock-absorbing seat will be subjected to axial impact, and the shock-absorbing spring or the shock-absorbing rubber pad can play a shock-absorbing role. [0003] The shock-...
