Drilling machine faucet

Abstract

The utility model relates to a drilling machine faucet which comprises a shell and a pipeline assembly arranged in the shell, the shell comprises an upper shell body and a lower shell body, and the upper shell body and the lower shell body are both aluminum alloy shell bodies. The pipeline assembly comprises a slurry channel formed in the shell, and steel balls are arranged between the slurry channel and the shell. The device further comprises a slurry leakage pipeline, and when slurry in the slurry channel leaks, leaked slurry flows out through the slurry leakage pipeline. The blocking ring is arranged on the outer ring of the slurry channel in a sleeving mode and used for blocking leaked slurry, and the steel balls are located on the lower portion of the blocking ring. Two sealing rings are arranged on the outer circle of the blocking ring. The bearing is prevented from being blocked after thermal expansion under the high-speed rotating working condition, and the service life of the faucet is prolonged.

Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a drilling rig faucet. Background Art

[0002] The faucet is a crucial connector for establishing a mud circulation channel during geological drilling and is an essential component of a pile driver. Currently, conventional faucets are attached to the top of the drill pipe. During pile driving, the drill pipe rotates while the faucet does not, allowing mud to enter the drill pipe through the faucet. Existing faucets have two problems: 1. The steel housing continuously collides with the steel balls inside during rotation, generating significant heat and causing them to expand and become stuck. 2. Mud leaks within the faucet cannot be detected promptly. These issues reduce work efficiency and shorten the service life of drilling rig faucets. Utility Model Content

[0003] The utility model aims to overcome the defects of the prior art and provide a drilling rig faucet.

[0004] In order to solve the above technical problems, the utility model is achieved as follows:

[0005] A drilling rig faucet, comprising a housing and a pipe assembly arranged in the housing, wherein the housing comprises an upper housing and a lower housing, both of which are aluminum alloy housings;

[0006] The pipeline assembly comprises a mud channel opened inside the shell, and a steel ball is arranged between the mud channel and the shell.

[0007] The drilling rig faucet is characterized in that it also includes a slurry leakage pipe. When the slurry leaks in the slurry channel, the leaked slurry flows out through the slurry leakage pipe.

[0008] The drilling rig faucet is characterized in that it also includes a blocking ring, which is sleeved on the outer ring of the mud channel and is used to block the leakage of mud liquid, and the steel ball is located at the lower part of the blocking ring.

[0009] The drilling rig faucet is characterized in that two sealing rings are provided on the outer ring of the blocking ring.

[0010] The beneficial effects of the present invention are as follows: As can be seen from the above technical solution, the present application provides a drilling rig faucet, the outer shell of which is made of aluminum alloy. This has a greater expansion coefficient than steel, low rigidity, and a certain degree of deformation. This can avoid the problem of bearings getting stuck due to heat expansion under high-speed rotation conditions, and the aluminum alloy material has better heat dissipation performance. The provision of a slurry leakage pipe can promptly detect whether the faucet is leaking, making operation safer and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0012] Figure 1 This is a schematic diagram of the structure of this application.

[0013] Figure 2 for Figure 1 Middle AA section view. DETAILED DESCRIPTION

[0014] The following will clearly and completely describe the technical solutions of the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection requested by this application.

[0015] like Figure 1 、 2 As shown: A drilling rig faucet, comprising a housing and a pipe assembly arranged in the housing,

[0016] The shell includes an upper shell and a lower shell, and the upper shell 11 and the lower shell 12 are both aluminum alloy shells 1; the outer shell is made of aluminum alloy, which has a greater expansion coefficient than steel, low rigidity, and a certain amount of deformation, which can avoid the problem of the bearing getting stuck after heating and expanding under high-speed rotation conditions, and the aluminum alloy material has better heat dissipation performance.

[0017] The pipe assembly includes a mud channel 2 formed within the housing, with a steel ball 3 disposed between the mud channel and the housing. It also includes a leakage pipe 4. When mud leaks from the mud channel, the leaked mud flows out through the leakage pipe. The provision of the leakage pipe allows for timely detection of faucet leakage.

[0018] The invention also comprises a blocking ring 5, which is sleeved on the outer ring of the mud channel to block the leakage of mud liquid, and the steel ball is located at the lower part of the blocking ring. The outer ring of the blocking ring is provided with two sealing rings 6.

[0019] The above are only embodiments provided for this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
