Abstract
Description
Technical Field
[0001] The present application relates to the field of drilling auxiliary tools, and more particularly to a high-speed drilling faucet. Background Art
[0002] In recent years, artificial diamond rope core drilling technology has been widely used in geological exploration systems. The most significant advantages of this technology are short auxiliary time, high efficiency, reliable quality and low labor intensity of workers. As an auxiliary tool in the drilling process, the effect of the faucet is directly related to the drilling efficiency and the length of auxiliary time.
[0003] Although some faucets have a reasonable structure, they are too large in size. When working, they will vibrate and shake for a long time due to the high speed. In serious cases, it will cause accidents such as bending and breaking of the drill rod. The easily worn parts of the faucet are non-standard parts, and the efficiency of later replacement is greatly reduced. Utility Model Content
[0004] In order to solve the above problems, the present application provides a high-speed drilling faucet.
[0005] The high-speed drilling faucet provided in this application adopts the following technical solution:
[0006] A high-speed drilling faucet comprises a lifting cap, a water inlet, a mud hole, a shell, a main shaft and a guide sleeve. The lifting cap is provided with a water inlet on the side. The main shaft and the guide sleeve are adaptably connected and are connected with the water inlet up and down. The guide sleeve and the packing seat are provided with a group of packings. The packings are combined with a compression spring to increase the sealing effect.
[0007] Furthermore, a compression O-ring is provided between the packing seat and the lifting cap, and the compression O-ring is used for sealing between the packing seat and the lifting cap.
[0008] Furthermore, a mud hole is provided on the surface of the lifting cap to detect whether the packing seal fails.
[0009] Furthermore, a water outlet is provided inside the filling seat.
[0010] Furthermore, an angular contact bearing and a thrust ball bearing are arranged vertically between the main shaft and the housing, and an elastic retaining ring for a hole is provided above the angular contact bearing.
[0011] Furthermore, a thrust washer and a round nut are arranged above the angular contact bearing.
[0012] In summary, the present application includes at least one of the following beneficial technical effects:
[0013] The utility model seals the packing seat and the lifting cap by pressing the O-ring, and a water outlet is arranged inside the packing seat. If the packing seal fails, mud will flow out from the mud hole on the lifting cap, and the packing needs to be replaced, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
