Embodiment Construction
[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] Please also refer to Figure 1 to Figure 4 , the rotary drilling rig faucet provided by the present invention will now be described. The rotary drilling rig faucet includes a hollow shaft 100, an upper connection assembly 200 arranged on the upper end of the hollow shaft 100 and used to connect with the drill pipe, and a slurry feeding tee sleeved on the outer periphery of the hollow shaft 100 and communicated with the inner cavity of the hollow shaft 100 700, the mud pipeline 300 whose outlet is connected to the side inlet of the slurry feeding tee 700, th...

The invention provides a rotary drilling rig faucet, and relates to the technical field of construction equipment. The rotary drilling rig faucet includes a hollow shaft, an upper connecting assembly,a mud pipeline, a mud feeding tee, a reverse torsion assembly, and a lower connecting assembly. The rotary drilling rig faucet is arranged between a drill pipe and a drill bit of a drilling rig, thehollow shaft communicates with the mud pipeline to carry out mud transportation so as to realize the effect of mud from the stationary pipeline to the rotary drill bit; the subsequent mud is discharged upward from a hole drilled by the drill bit, and the cooling effect of the mud on the drill bit is effectively ensured; a good effect can be formed through an arrangement of the reverse torsion assembly abutting against a borehole wall, torque produced during rotation of the hollow shaft is counteracted, the stability of the external mud pipeline outside the hollow shaft is realized, and the stability of the drilling rig drilling in the axis direction is ensured at the same time.
Description
technical field [0001] The invention belongs to the technical field of building construction equipment, and more specifically relates to a rotary drilling rig faucet. Background technique [0002] Rotary drilling rig is a kind of construction machine suitable for hole-forming operations in building foundation engineering. Ordinary rotary drilling rigs can only work on soft soil layers such as sandy soil layers, clay layers, and silty soil layers, and are helpless for rock layers. Drilling bits must be selected for rock formation construction, and the drilling bits will generate a lot of heat during the drilling process, so they need to be cooled during drilling, which requires the use of drilling rigs and faucets. Since ordinary faucets only It can cooperate with the drilling rig to drill above the ground, but it is not suitable for entering and leaving the rock formation together with the drill bit, so it cannot be effectively applied to the drilling of the rock formation, ...
