[0032] Figure 1 Schematic diagram of the structure of this embodiment, Figure 2 yes Figure 1 The main structure diagram of Figure 1 and Figure 2 As shown, this embodiment provides an oil casing wire guard removal device, including a support 1, an adjustment component 2 and a movable wing 3.

[0033] The support 1 includes a main body 11 and a connecting structure 12 provided on one side of the main body 11. The main body 11 is provided with a threaded hole 110, and the adjustment component 2 is connected to the main body 11 through the threaded hole 110. Figure 3 yes Figure 1 The top view structural diagram of Figure 3 As shown, the connection structure 12 includes a plurality of fixed plates 121 arranged along the circumference of the main body 11 , the movable wings 3 are installed between two adjacent fixed plates 121 , and the plurality of movable wings 3 are arranged at intervals.

[0034] The adjustment assembly 2 includes an adjustment rod 21 and a conical column 22. A threaded structure that cooperates with the threaded hole 110 is provided on the adjustment rod 21. The adjustment rod 21 passes through the main body 11 through the threaded hole 110, so that the two ends of the adjustment rod 21 are respectively located on both sides of the main body 11, and the conical column 22 is connected to one end of the adjustment rod 21.

[0035] In this embodiment, the movable wings 3 include multiple movable wings 3, which are evenly distributed along the circumference of the main body 11, ensuring that the wire guard is evenly stressed and effectively protecting the wire guard from damage. The movable wings 3 are movably connected to the connecting structure 12, one end of the movable wing 3 abuts on the conical column 22, and the other end of the movable wing 3 is used to clamp the casing wire guard. The conical column 22, on the one hand, can enable the movable wing 3 to abut against it, so that the movable wing 3 can move along its outer wall to enable the movable wing 3 to achieve the purpose of biting or releasing the oil casing wire guard. On the other hand, the conical column 22 can prevent the adjustment rod 21 from falling out during use.

[0036] In this embodiment, the movable wings 3 are provided in three groups, so that the support 1 forms a three-grab structure to ensure that the wire guard is evenly stressed. Specifically, the movable wings 3 are provided with pin holes 30 , and the movable wings 3 are connected to the fixing plate 121 through fixing pins 4 .

[0037] Figure 4 yes Figure 2 BB cross-sectional structure diagram, as shown in Figure 4 As shown, the movable wing 3 in this embodiment comprises an integrally formed movable portion 31 and a clamping portion 32, both arranged at an obtuse angle. The end of the movable portion 31 abuts against the conical column 22. A pin hole 30 is provided in the movable portion 31. During use, as the adjustment rod 21 extends or rotates, the movable wing 3 engages or releases the oil casing thread guard.

[0038] The thread structure in this embodiment includes a partially trapezoidal thread. The partially trapezoidal thread has a larger inclination angle and stronger connectivity. Compared with ordinary threads, it has less wear after continuous use and higher stability. By providing a partially trapezoidal thread on the adjusting rod 21, the service life and stability of the adjusting rod 21 can be improved, thereby improving the service life of this oil casing wire protection removal device.

[0039] As an optional embodiment, anti-drop caps are provided on both sides of the fixing pin 4 to improve the stability of the movable wing 3 during operation.

[0040] As an optional embodiment, it also includes a slip tooth 5, wherein the clamping portion 32 is provided with a slip tooth fixing groove, and the slip tooth 5 is installed in the slip tooth fixing groove. By configuring the slip tooth 5 at the lower part of the movable wing 3, the oil casing wire guard can be tightened to prevent slipping.

[0041] In actual production and use, the movable wings 3 can be set to different sizes and matched with corresponding slip teeth 5 to adapt to oil and casings of different sizes such as 18-5 / 8", 13-3 / 8", 9-5 / 8", 7", and 4-1 / 2".

[0042] As an optional implementation, in order to realize the automated operation of the oil casing wire guard removal device, the oil casing wire guard removal device in this embodiment further includes a power device, which is connected to the adjustment rod 21 .

[0043] Specifically, an internal hexagonal or external hexagonal screw is provided at the other end of the adjusting rod 21, and the power device includes an electric or pneumatic wrench. When in use, after the movable wing 3 is installed on the oil casing guard, the electric or pneumatic wrench is used in conjunction with the adjusting rod 21. As the adjusting rod 21 is extended, the movable wing bites the oil casing guard, and the oil casing guard is automatically disassembled.

[0044] The working process of this embodiment is:

[0045] During use, the movable wings 3 are placed on the outer wall of the oil casing and wire guard. Using an electric or pneumatic wrench, the adjusting rod 21 is extended. The movable wings 3 gradually engage the oil casing and wire guard, which then drives the wire guard shackle, achieving automatic removal of the wire guard. The operation is simple and can be completed by one person, achieving efficient operation.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
