Description

Technical Field

[0001] This utility model relates to the field of oiling equipment, specifically to a tooling for coating the surface of drill pipes with oil. Background Technology

[0002] In oil drilling, the drill pipe, as a key component connecting the drill bit to surface equipment, directly affects drilling efficiency and operational safety. During downhole operations, the drill pipe is exposed to harsh environments such as high temperature, high pressure, and high corrosion, making its surface susceptible to wear, corrosion, and fatigue damage, thus shortening its service life and increasing maintenance costs. Therefore, applying oil to the drill pipe surface can effectively improve its durability.

[0003] The existing method of coating drill rods involves using an electric clamp to immerse the drill rod in an oil tank for feeding. When the drill rod is removed, a lot of oil is spilled, resulting in serious oil waste. In addition, the drill rods come in various lengths, and the existing immersion equipment has a limited range of applications. Therefore, a tooling for coating drill rod surfaces with oil is needed.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] Please see Figure 1-3 The tooling for oiling the surface of a drill pipe shown includes a base 1, with a recovery box 2 and a sliding seat plate 3 respectively arranged on both sides of the base 1. Multiple columns 4 are arranged on the sliding seat plate 3, and a slidable bracket 5 is connected to each column 4. Each bracket 5 is provided with a positioning oiling assembly. The positioning oiling assembly includes a positioning insert plate 601, a cylinder 602, an oil wiping plate 603, and a rotating device 604. The positioning insert plate 601 has a positioning hole 6011, and multiple oil outlet holes 6012 are provided on the inner wall of the positioning hole 6011 on the positioning insert plate 601.

[0021] A protrusion is provided at one end of the recovery box 2 near the translation seat plate 3, which can increase the range of oil collection in the recovery box 2, and the misalignment of the protrusion with the translation seat plate 3 can avoid interference with the sliding adjustment of the translation seat plate 3.

[0022] The translation plate 3 is slidably connected to the base 1. The base 1 can guide the sliding adjustment of the translation plate 3. A locking screw is provided on the translation plate 3. The locking screw can fix the position of the translation plate 3 after adjustment.

[0023] Multiple uprights 4 are arranged in an array on the sliding base plate 3. The mounting bracket 5 can be raised and lowered on the sliding base plate 3 to adjust its position. After adjustment, the mounting bracket 5 is fixed to the uprights 4 by bolt assembly. Grooves are made on the uprights 4, and protrusions corresponding to the grooves are provided on the mounting bracket 5 to prevent the mounting bracket 5 from deflecting when adjusting its position.

[0024] The positioning plate 601 is fixedly connected to the rotating end of the rotating device 604. The piston rod of the cylinder 602 drives the oil wiping plate 603 to perform the oil wiping action. A guide post is fixedly connected to the oil wiping plate 603 and slidably connected to the positioning plate 601. A clearance hole is opened on the oil wiping plate 603, and a brush is provided on the inner wall of the clearance hole. When the oil wiping plate performs the oil wiping action, the brush can brush the oil onto the surface of the drill rod.

[0025] The working principle of this utility model is as follows: Before applying oil, the distance between the translation plate 3 and the recovery box 2 can be adjusted according to the length of the drill rod. After adjusting the position by sliding the translation plate 3, it is fixed by locking screws. Then, the angle of the positioning plate 601 is adjusted. The positioning plate 601 is driven to rotate by the rotating device 604 to adjust the angle. Finally, the height of the card seat 5 is adjusted by loosening the bolt assembly and sliding the card seat 5 to adjust the height. After the adjustment is completed, the bolt assembly is tightened.

[0026] During oiling, the drill rod is placed on the positioning plate 601 along the positioning hole 6011. After the drill rod is placed, oil is applied to the surface of the drill rod through the oil outlet 6012 (the oil outlet is connected to the external oil supply system). Then, the piston rod of the cylinder 602 extends and retracts multiple times. During this process, the brush on the oil wiping plate 603 brushes the oil onto the surface of the drill rod. Excess oil will drip into the recovery box 2 for collection.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
