[0017] The features and performances of the oil pumping unit foundation positioning and mounting device are further described in detail in combination with the embodiments.

[0018] In the installation process of the oil pumping unit foundation, the positioning of the oil pumping unit foundation is particularly important, and the accuracy of the positioning determines whether the oil pumping unit foundation can be stably operated in the future. The concept of the oil pumping unit foundation positioning and mounting device is to design a device which can be cooperated with the wellhead short section and the oil pumping unit foundation and can limit the distance and angle between the wellhead short section and the oil pumping unit foundation.

[0019] Based on the above concept, as Figure 1In a basic embodiment, the pumping unit foundation positioning and installing device comprises an arc-shaped positioning sheet 2, the inner diameter of the positioning sheet 2 is equal to the outer diameter of the wellhead nipple 5, so that the inner wall of the positioning sheet 2 can be attached to the cylindrical wellhead nipple 5, a structural member 3 is installed on the positioning sheet 2 in the direction away from the opening of the positioning sheet 2, which does not affect the cooperation between the positioning sheet 2 and the wellhead nipple 5, a U-shaped frame 1 is installed on the structural member 3, the distance between the positioning sheet 2 and the U-shaped frame 1 is limited by connecting them, the U-shaped frame 1 is opposite to the opening direction of the positioning sheet 2, the width of the U-shaped frame 1 is equal to the width of the end surface of the pumping unit foundation 4, so that the U-shaped frame 1 can cooperate with one end of the pumping unit foundation 4, the distance from the two inflection points 8 of the U-shaped frame 1 to the center of the positioning sheet 2 is equal, which limits the direction of the pumping unit foundation 4 relative to the wellhead nipple 5.

[0020] As Figure 3 In a preferred embodiment, the structural member 3 comprises a positioning rod 7, the two ends of the positioning rod 7 are connected to the positioning sheet 2 and the U-shaped frame 1 respectively, so as to limit the distance between the positioning sheet 2 and the U-shaped frame 1, the use of the positioning rod can facilitate the observation of whether there is deformation and damage, and different lengths of positioning rods can be replaced according to different site requirements. In other embodiments, steel bars or other steel materials can also be used, although the bending resistance is relatively low, but similar effects can also be achieved. The positioning rod 7 is installed perpendicular to the width direction of the U-shaped frame 1, and the connection position of the positioning rod 7 and the U-shaped frame 1 is the midpoint of the width direction of the U-shaped frame 1, in this installation manner, the force acting on the positioning rod 7 during work is in the axial direction, which reduces the possibility of deformation of the positioning rod 7 and improves the service life of the pumping unit foundation positioning and installing device. In other embodiments, the positioning rod 7 is installed at an angle of 70° or other degrees with the width direction of the U-shaped frame 1, although the strength is relatively low, but similar effects can also be achieved.

[0021] In a preferred embodiment, the structural member 3 comprises at least two structural rods 6, the two ends of the structural rod 6 are connected to the positioning sheet 2 and the U-shaped frame 1 respectively, the structural rod 6 is installed symmetrically relative to the direction from the center of the positioning sheet 2 to the midpoint of the width of the U-shaped frame 1, the structural rod 6 not only limits the distance between the positioning sheet 2 and the U-shaped frame 1, but also uniformly disperses the force acting on it during work, which reduces the possibility of deformation and damage of the pumping unit foundation positioning and installing device. In other embodiments, one structural rod can also be provided, and the specific manner is as described in the preferred embodiment of the positioning rod, and similar effects can be achieved. The structural rod 7 is installed at the same position on the positioning sheet 2, at this time, the structural rod 7 and the bottom edge of the U-shaped frame 1 form an isosceles triangle structure, which has good supporting capacity, low possibility of deformation and damage, and high strength. In other embodiments, the structural rod 7 is not installed at the same position on the positioning sheet 2, although the strength is reduced, similar effects can also be achieved.

[0022] In a preferred embodiment, the U-shaped frame 1 is composed of angle iron, the opening of which is directed to the inside of the U-shaped frame 1, and the U-shaped frame 1 can be placed above the end of the pumping unit foundation 4 without additional locking structure, simplifying the positioning process and saving labor and time. In other embodiments, other existing steel materials are used, although additional fixing is required, but similar effects can be achieved.

[0023] As Figure 2 When installing the pumping unit foundation 4, the positioning piece 2 of the pumping unit foundation positioning and installing device is attached to the wellhead nipple 5, and then a positioning line is drawn along the U-shaped inner contour of the U-shaped frame 1 on the ground, indicating the installation direction and position of the pumping unit foundation 4. After the pumping unit foundation 4 is transported to the installation site, the pumping unit foundation 4 is hoisted to the positioning line using engineering machinery, and then the U-shaped frame 1 of the pumping unit foundation positioning and installing device is assembled with the end of the pumping unit foundation 4 close to the wellhead nipple 5. At this time, the positioning piece 2 is close to the wellhead nipple 5, the pumping unit foundation 4 is hoisted and moved so that the positioning piece 2 is on the outer surface of the wellhead nipple 5, the position of the pumping unit foundation 4 is adjusted, and then the pumping unit foundation 4 is lowered and installed. According to the calculation, each time the device is used for auxiliary positioning of pumping unit foundation installation, about 7000 yuan of labor and heavy machinery costs can be saved.

[0024] The above is only a preferred embodiment of the present application, and is not used to limit the present application. The patent protection scope of the present application is subject to the claims, and any equivalent structural changes made according to the content of the specification and drawings should also be included in the protection scope of the present application.
