[0018] In order to make the person skilled in the art better understand the technical scheme in the utility model, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the patent, other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the patent.

[0019] Please refer to Figure 1 and Figure 2 The embodiment provides a sucker rod centralizer installation tool, which comprises a fixing mechanism 1, a pressing mechanism 2, a power arm 3 and a base 4.

[0020] The fixing mechanism 1 is an "L" shaped structure, and the upper end thereof is welded and fixed with one end of the pressing mechanism 2. The lower end of the fixing mechanism 1 is provided with a hook, and the hook can be clamped below the sucker rod 6, so that the lower end of the fixing mechanism is supported below the sucker rod 6 at the installation position. Therefore, the stability of the tool during installation of the sucker rod centralizer 5 can be improved, and the sucker rod 6 is prevented from shaking.

[0021] The pressing mechanism 2 is located at one side of the fixing mechanism 1, and a groove for accommodating the sucker rod centralizer 5 is arranged below the pressing mechanism 2. The sucker rod centralizer 5 to be installed can be accommodated in the groove of the pressing mechanism 2. Specifically, the pressing mechanism comprises two plates, and a certain included angle is formed between the two plates, and the sucker rod centralizer 5 is installed in the included angle. In this way, the operator can more conveniently install the sucker rod centralizer 5, and the installation efficiency and accuracy are improved.

[0022] The power arm 3 comprises a pressing rod 302 and a support rod 301. One end of the pressing rod 302 is welded and fixed with the upper end of the pressing mechanism 2, and the other end is nested with a handle to facilitate the operator to exert force. The support rod 301 is welded and supported between the pressing rod 302 and the pressing mechanism 2, and plays a supporting and reinforcing role. The operator only needs to exert a small force through the handle, and the installation work of the sucker rod centralizer 5 can be easily completed through the amplification of the power arm 3. Therefore, the lever principle in physics is fully utilized, the labor intensity of the operator is reduced, and the work efficiency is improved.

[0023] The base 4 comprises a vertical plate 401 and a bottom plate 402. The vertical plate 401 is provided with a groove for accommodating the sucker rod 6, which can effectively avoid the left and right rolling of the sucker rod, and ensure the stability of the sucker rod centralizer 5 during installation. The bottom plate 402 is welded at the bottom of the vertical plate 401, and a reinforcing plate 403 is further welded and fixed between the vertical plate 401 and the bottom plate 402, further improving the stability and load-bearing capacity of the base. In the embodiment, the base 4 is provided with at least two, and the appropriate number can be selected for use according to actual needs.

[0024] In specific use, the operator first puts the sucker rod 6 into the groove of the base 4, then clamps the hook of the fixing mechanism 1 under the sucker rod 6, and stably connects the whole device to the sucker rod 6. Then, the sucker rod centralizer 5 to be installed is put into the groove under the pressing mechanism 2, and the position of the pressing mechanism 2 is adjusted to ensure that the sucker rod centralizer 5 can be accurately placed at the predetermined position. Finally, the operator holds the handle of the power arm 3 and applies appropriate force, and installs the sucker rod centralizer 5 on the sucker rod 6 body through the amplification of the power arm 3. The whole installation process is simple and fast, greatly improving the work efficiency and installation accuracy.

[0025] In summary, the sucker rod centralizer installation tool has the advantages of simple structure, convenient operation, high installation efficiency and good stability, and is very suitable for application in the oil field site with variable environment.
