Description

Technical Field

[0001] This utility model relates to the technical field of tools for removing wire guards, specifically to a reverse-bow type wire guard removal tool. Background Technology

[0002] In geological drilling and oil extraction engineering, appropriate specifications of geological oil casing need to be installed at different well depths according to the exploration objectives and subsequent operation plans. To prevent the threads of the oil casing ends from failing due to collisions and wear during storage, transportation, and hoisting, thread protectors are usually used to protect them. However, during the casing installation process, the thread protectors must be removed to complete the thread connection of the casing string. This process has become a core issue restricting construction efficiency and casing protection effectiveness: if the thread protectors are removed after the casing is hoisted to the drilling platform, high-altitude operations will consume a lot of extra time, seriously slowing down the casing string connection progress and disrupting the continuity of construction; if the thread protectors are removed in advance on the ground before hoisting, the unprotected threads are easily damaged by collisions and friction during hoisting and transportation, and the exposed threads may be affected by foreign objects and environmental corrosion, leading to dead threads during subsequent casing string connections, i.e., the threads are stuck and cannot be smoothly screwed or disassembled, thus affecting the connection quality. The existing reverse-bow back type wire cap removal tool cannot conveniently, simply and effectively address the above problems, cannot meet the needs of efficient and continuous operation, and is very likely to cause disassembly failure, damage to the sleeve, waste, increase construction costs, and affect construction efficiency.

[0007] As a further improvement of this utility model, the distance between the inner clamping arm and the outer clamping arm is adapted to the wall thickness of the wire protector.

[0026] like Figure 1As shown, a tool for removing a reverse-bow-shaped wire cap according to this utility model includes: a reverse-bow-shaped main rod 1, a threaded handle portion 2, and a clamping portion 3. One end of the reverse-bow-shaped main rod 1 is provided with the threaded handle portion 2, and the other end is provided with the clamping portion 3. The clamping portion 3 includes a clamping inner arm 31 and a clamping outer arm 32 arranged parallel to each other on the same side of the reverse-bow-shaped main rod 1. The clamping inner arm 31 and the clamping outer arm 32 form a clamping opening for clamping the inner and outer walls of the wire cap. The ends of the clamping inner arm 31 and the clamping outer arm 32 away from the reverse-bow-shaped main rod 1 are provided with protrusions 33, which increase the friction between the clamping inner arm 31, the clamping outer arm 32, and the inner and outer walls of the wire cap.

[0027] Specifically,

[0028] like Figure 1 As shown, in the above embodiment, preferably, the distance between the inner clamping arm 31 and the outer clamping arm 32 is adapted to the wall thickness of the wire protector cap, so as to achieve effective and stable clamping of the wire protector cap.

[0029] In the above embodiments, preferably, the reverse-bow-shaped main rod 1, the inner clamping arm 31, and the outer clamping arm 32 are all made of threaded steel bars. In this embodiment, the reverse-bow-shaped main rod 1, the inner clamping arm 31, the outer clamping arm 32, and the threaded handle portion 2 are all connected by argon arc welding.

[0030] In the above embodiments, preferably, the shape of the protrusion 33 includes a semi-elliptical protrusion or a hemispherical protrusion; the outer surface of the semi-elliptical protrusion or the hemispherical protrusion is provided with friction texture. In this embodiment, the height of the protrusion 33 is not greater than 1 cm.

[0031] In the above embodiments, preferably, the axial extension directions of the inner clamping arm 31 and the outer clamping arm 32 are perpendicular to the axial extension direction of the upper end of the reverse-bow-shaped main rod 1. In this embodiment, the inner clamping arm 31 and the outer clamping arm 32 together with the reverse-bow-shaped main rod 1 form an approximate letter "F" shape.

[0032] In the above embodiments, preferably, the length of the inner clamping arm 31 is less than the length of the outer clamping arm 32. In this embodiment, preferably, the length of the inner clamping arm 31 is 1 / 4 of the length of the outer clamping arm 32.

[0033] How to use this embodiment:

[0034] Align the clamping part 3 of the tool with the wire protector cap to be removed, so that the inner clamping arm 31 extends into the inside of the wire protector cap and fits against its inner wall, and the outer clamping arm 32 fits against the outer wall of the wire protector cap, so that the wire protector cap tube wall is completely embedded in the clamping opening between the two; at the same time, ensure that the protrusions 33 at the ends of the inner clamping arm 31 and the outer clamping arm 32 are in close contact with the inner and outer walls of the wire protector cap, and form a stable engagement using the protrusions 33 and friction texture;

[0035] The operator holds the threaded handle 2 and adjusts the force angle by using the mechanical structure of the reverse bow-shaped main rod 1 to ensure a stable grip and that the force direction is consistent with the direction of loosening the thread protector cap.

[0036] Rotate the threaded handle 2 slowly and evenly, and transmit the torque to the clamping part through the reverse bow-shaped main rod 1, causing the thread protector to rotate synchronously. Use the friction of the protrusion 33 to prevent slippage; continue rotating until the thread protector is completely unscrewed from the sleeve thread to complete the disassembly.

[0037] After disassembly, clean the oil, dust or foreign matter adhering to the surface of the clamping part 3 and the protrusion part 33 to keep the tool clean and avoid impurities affecting the clamping effect next time.

[0038] Advantages of this utility model:

[0039] This utility model achieves safe and efficient disassembly of the wire protector by using a reverse-bow-shaped main rod 1 in conjunction with a threaded handle part 2 and a clamping part 3 with a specific structure, thus solving the problem of untimely disassembly and inefficient continuous operation when oil casing is hoisted to the drilling platform.

[0040] This utility model achieves low tool cost, simple processing and design, and sturdiness and durability by using a reverse bow-shaped main rod, inner clamping arm and outer clamping arm made of threaded steel bars and connecting the various parts by argon arc welding, thus solving the problems of high cost and easy damage of existing tools.

[0041] This utility model optimizes the connection structure between the reverse-bow-shaped main rod and the inner and outer clamping arms, as well as the design of the threaded handle part 2, making it ergonomic and easy to operate. It solves the problems of existing tools being complex to operate and requiring high skill from operators.

[0042] This invention improves the efficiency of removing wire caps, increasing the working efficiency to 3 minutes per cap (compared to 6-10 minutes per cap), greatly shortening the construction time, saving the construction cycle, ensuring efficient and continuous operation, solving the problem of slow construction progress, and generating significant economic benefits.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
