In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying anything.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a filling device for oil wells, comprising a material box 1, a feeding component, and a supporting component. The device shown in this technical solution is used to fill the cylinder 2 of an oil well. The cylinder 2 can refer to the wellbore or the pipeline within the well, depending on the specific implementation.

[0027] The feeding component includes a rotating plate 14, a motor 16, a positioning tube 5, and two discharge pipes 13. The rotating plate 14 is rotatably mounted on the bottom wall of the material box 1, and has two discharge holes. The upper ends of the two discharge pipes 13 are fixedly mounted to the rotating plate 14, and the two discharge pipes 13 are respectively connected to the two discharge holes. The motor 16 is fixedly mounted on the outer wall of the material box 1, and is driven by the rotating plate 14. The positioning tube 5 is sleeved on the outside of the two discharge pipes 13.

[0028] The main function of the rotating plate 14 is to evenly distribute the material in the material box 1 into the two discharge pipes 13 through the discharge hole by its rotation. This design ensures that the material can enter the discharge pipes 13 evenly, thereby achieving a uniform filling effect. The main function of the motor 16 is to provide power for the rotation of the rotating plate 14. The upper part of the positioning pipe 5 is a straight pipe section, and the lower part is a trumpet-shaped pipe section. The main function of the positioning pipe 5 is to ensure that the central axis of the discharge pipe 13 coincides with the central axis of the cylinder 2 at the wellhead, thereby achieving precise material discharge. The trumpet-shaped bottom design allows the positioning pipe 5 to fit tightly with the cylinder 2, avoiding material spillage and waste. The trumpet-shaped lower part of the positioning pipe 5 covers the upper end of the cylinder 2. The main function of the discharge pipe 13 is to transport the material in the material box 1 to the underground through the discharge hole.

[0029] The supporting components include multiple fixing assemblies, each of which is fixedly installed on the outer side wall of the material box 1. Each fixing assembly includes a telescopic member 4 and a fixing plate 7. The telescopic member 4 is fixedly installed on the lower outer side wall of the material box 1, and the fixing plate 7 is fixedly installed on the output shaft end of the telescopic member 4. The telescopic member 4 drives the fixing plate 7 to move up and down. The telescopic member 4 is connected to the positioning tube 5 via a transmission mechanism, and the telescopic member 4 drives the positioning tube 5 to move up and down.

[0030] The telescopic component 4 includes, but is not limited to, a servo electric cylinder, an electric telescopic rod, or a hydraulic rod. The main function of the telescopic component 4 is to provide lifting power, driving the fixed plate 7 and the positioning tube 5 to move up and down through its telescopic movement. This design allows the device to adjust its height as needed during filling, ensuring that the positioning tube 5 accurately aligns with the wellhead cylinder 2. Several limiting pins are fixedly connected to the bottom surface of the fixed plate 7. The fixed plate 7 moves up and down driven by the telescopic component 4. After the fixed plate 7 contacts the ground, the limiting pins below the fixed plate 7 insert into the surface soil, strengthening the contact between the fixed plate 7 and the ground, ensuring the stability and support of the device. The telescopic component 4 also supports the material box 1.

[0031] Specifically, the feeding component also includes a mounting plate 6, a first gear 10, and a second gear 15. The mounting plate 6 is L-shaped in general. The upper end of the mounting plate 6 is fixedly connected to the outer side wall of the material box 1. The motor 16 is fixedly mounted on the mounting plate 6. The second gear 15 is fixedly mounted on the output shaft end of the motor 16. The first gear 10 is fitted on the lower outer side wall of the rotating plate 14 and the two are fixedly connected. The first gear 10 meshes with the second gear 15.

[0032] The main function of the mounting plate 6 is to provide a stable mounting platform for the motor 16, ensuring its stability during operation. The first gear 10 and the second gear 15, through meshing transmission, convert the rotational motion of the motor 16 into the rotational motion of the rotating plate 14, achieving uniform material feeding. This design not only improves the efficiency and uniformity of filling but also ensures the stability and reliability of the transmission system.

[0033] More specifically, the feeding component also includes multiple fixed posts 11, multiple sliding rods 9, and multiple stops 12. The sliding rods 9 are arranged in a circular array around the positioning tube 5, and one end of each sliding rod 9 is fixedly connected to its outer side wall. The upper end of each fixed post 11 is fixedly connected to the bottom wall of the material box 1. The fixed post 11 passes through the other end of each sliding rod 9 and the two are slidably connected. The stops 12 are fixedly installed at the lower end of each fixed post 11.

[0034] The fixed post 11 passes through the sliding rod 9, providing a sliding guide for the sliding rod 9 and ensuring that the sliding rod 9 maintains linear movement during lifting and lowering, preventing the sliding rod 9 from deviating or getting stuck during movement. The length and position design of the fixed post 11 can limit the sliding range of the sliding rod 9, preventing excessive sliding of the sliding rod 9 from causing structural damage or functional failure. The sliding rod 9 is slidably connected to the fixed post 11, allowing the positioning tube 5 to move up and down under the guidance of the fixed post 11. This design allows the positioning tube 5 to adjust its height as needed to achieve precise positioning. The main function of the stop 12 is to limit the sliding range of the sliding rod 9, preventing excessive sliding of the sliding rod 9 from causing structural damage or functional failure. Through its fixed connection with the fixed post 11, the stop 12 can effectively prevent the sliding rod 9 from excessively sliding on the fixed post 11.

[0035] More specifically, the fixing assembly also includes a connecting plate 8 and a spring 17. The connecting plate 8 is generally L-shaped, and its lower end is fixedly connected to the fixing plate 7. The fixing post 11 extends longitudinally through the upper end of the connecting plate 8 and the two are slidably connected. The spring 17 is sleeved on the outer wall of the fixing post 11, and its upper and lower ends are fixedly connected to the connecting plate 8 and the sliding rod 9, respectively.

[0036] The main function of the connecting plate 8 is to connect the fixed plate 7 to the fixed column 11, ensuring that the fixed plate 7 can move smoothly up and down under the drive of the telescopic component 4. The fixed column 11 provides a stable guide for the connecting plate 8, ensuring the accuracy and stability of its movement. The connecting plate 8, in conjunction with the spring 17, provides a buffering function, reducing the impact force generated when the fixed plate 7 contacts the ground or when the limiting pin inserts into the ground, thus extending the service life of the components. The spring 17 plays a role in buffering, resetting, and stabilizing support during the movement of the sliding rod 9. Through its elastic deformation, the spring 17 can effectively absorb and disperse the impact force, reducing damage to the sliding rod 9 and its connecting components, and extending the service life of the components. At the same time, the elastic force of the spring 17 ensures that the sliding rod 9 can automatically return to its initial position after each movement, maintaining the stability and reliability of the device. This design not only improves the stability and reliability of the device but also enhances its adaptability to different environments.

[0037] Specifically, the fixing component also includes a fixing seat 3, which is fixedly installed on the lower outer side wall of the material box 1, and the telescopic component 4 is fixedly installed on the fixing seat 3.

[0038] The fixed base 3 provides a stable installation platform for the telescopic component 4, ensuring the stability of the telescopic component 4 during operation, and also enhances the stability and reliability of the entire device through its structural design.

[0039] Specifically, multiple support legs are fixedly installed on the lower part of the material box 1, and each support leg is fixedly equipped with a wheel at its lower end.

[0040] The support legs, through their structural support and height adjustment functions, ensure the stability of the device during operation. Especially during filling, the support legs can withstand the weight of the device and the forces generated during filling, ensuring that the device does not shake or shift. The wheels, through their mobility and friction-reducing function, allow the device to move as needed on the support surface, improving its flexibility and portability.

[0041] In use, push the filling device above the wellhead, ensuring that the positioning tube 5 is aligned with the wellhead cylinder 2. The device moves to the designated position via support legs and wheels; the wheel design allows the device to be easily moved above the wellhead.

[0042] The support legs provide stable support, ensuring the stability of the device on the ground or other supporting surfaces.

[0043] Activate telescopic component 4. The output end of telescopic component 4 pushes the fixed plate 7 downward. The fixed plate 7 drives the connecting plate 8 downward, and the connecting plate 8 drives the sliding rod 9 downward through spring 17, thereby causing the positioning tube 5 to move downward. The trumpet-shaped bottom of the positioning tube 5 contacts the cylinder 2. As the positioning tube 5 continues to move downward, under the constraint of the cylinder 2, the positioning tube 5 will drive the device to move until the central axis of the positioning tube 5 coincides with the central axis of the cylinder 2, completing precise positioning. The sliding rod 9 contacts the stop block 12. The vertical section of the positioning tube 5 is located at the interface between the discharge pipe 13 and the cylinder 2, preventing the material from being blown away by the wind during subsequent discharge. Telescopic component 4 continues to push the fixed plate 7 downward, so that the fixed plate 7 contacts the ground, and the limiting pin inserts into the ground, fixing the device above the wellhead. Material is put into the material box 1, and the material enters the two discharge pipes 13 evenly through the material box 1.

[0044] The motor 16 is started, and the motor 16 drives the first gear 10 to rotate via the second gear 15. The first gear 10 meshes with the second gear 15, driving the rotating plate 14 to rotate, so that the discharge pipe 13 can evenly feed material into the well. The rotation of the rotating plate 14 is precisely controlled by the motor 16 to ensure that the material can enter the discharge pipe 13 evenly, thereby achieving a uniform filling effect. The flared bottom of the positioning pipe 5 is tightly connected to the cylinder 2 to ensure that the central axis of the discharge pipe 13 coincides with the central axis of the cylinder 2, avoiding material scattering and waste. The material enters the well through the discharge pipe 13, completing the filling operation.

[0045] After filling is complete, activate the telescopic component 4. The output end of the telescopic component 4 pulls the fixed plate 7 upward. The fixed plate 7 drives the connecting plate 8 upward, and the connecting plate 8 drives the sliding rod 9 upward via the spring 17, thereby causing the positioning tube 5 to move upward. The positioning tube 5 leaves the cylinder 2, and the device returns to its initial position.
