Problems solved by technology

However, these two types of faucets have simple structures and single functions, and the construction methods used are limited. They are generally used in places driven by a separate power head. For example, they are used with pile frames, and they are not suitable for use with rotary drilling rigs.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the drawings.

[0022] Such as figure 1 As shown, a pneumatic DTH hammer three-channel multi-function faucet includes a faucet body 6, and the faucet body 6 is provided with a DTH hammer gas supply pipeline for providing a gas source for the work of the DTH hammer. A gas lift reverse circulation gas supply pipeline for gas lift slag removal and a slag discharge pipeline for discharging gravel and sundries during construction. The bottom end of the faucet body 6 is provided with a connector for connecting with a drill pipe.

[0023] Preferably, as Figure 1 to Figure 5 As shown, the faucet body 6 includes a three-channel housing assembly 29, a rotating body 33 installed inside the bottom end of the three-channel housing assembly 29, and a rotating body 33 installed between the three-channel housing assembly 29 and the rotating body 33. The bearing 32 of the three-channel housing assembly 29 relative to...

Abstract

The invention discloses a three-channel multifunctional water tap of a pneumatic down-hole hammer. The three-channel multifunctional water tap comprises a water tap body (6), wherein a down-hole hammer gas supply pipeline used for providing a gas source for the operation of a down-hole hammer, a gas lift reverse circulation gas supply pipeline used for providing a gas source to realize gas lift slagging, and a slagging pipeline used for discharging crushed stones and impurities during construction are arranged inside the water tap body; a connecting piece used for being connected with a drill pipe is arranged at the bottom end of the water tap body. The three-channel multifunctional water tap adopts a three-channel water tap structure, can realize the independent operation of the down-hole hammer gas supply pipeline, the gas lift reverse circulation gas supply pipeline and the slagging pipeline, and is high in slagging efficiency and safe and environment-friendly.

Description

Technical field [0001] The invention relates to a pneumatic DTH hammer faucet structure of engineering machinery, in particular to a pneumatic DTH hammer three-channel multifunctional faucet, belonging to the technical field of pneumatic DTH hammers. Background technique [0002] Pneumatic down-the-hole hammer is a power tool at the bottom of the hole that uses the energy of compressed air to generate continuous impact loads. Specifically, compressed air drives the piston to reciprocate and strikes the hammer to transmit impact energy and high-frequency impact, and then drive by the power head to achieve rotary impact Double effect, and continuously and quickly discharge the broken material at the bottom of the hole to the ground through positive circulation or reverse circulation, with high construction efficiency. At present, the pneumatic down-the-hole hammer drilling technology has been highly recognized by the majority of users for its high drilling efficiency, low cost, few...
