[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a remote automatic braking device for a pumping unit, which includes: an annular fixed sleeve 2, a mounting plate 5 and a rotating rod 6. One end of the annular fixed sleeve 2 is fixedly connected to a support base 1. By installing the support base 1 above one end of the mounting plate 5, its position is fixed. The bottom end of the support base 1 is fixedly connected to the mounting plate 5. One end inside the annular fixed sleeve 2 is fixedly connected to a driving motor 11. When the driving motor 11 at one end inside the annular fixed sleeve 2 drives, it can drive the threaded sleeve 12 to rotate. After rotation, it is in threaded cooperation with the external thread 9, and thus the threaded position can be moved. The driving end of the driving motor 11 is fixedly connected to the threaded sleeve 12. Through the threaded cooperation between the threaded sleeve 12 and the external thread 9, the threaded movement can be achieved, which is convenient for tightening and releasing the hand brake lever 7 by extending and retracting according to requirements. Both ends of the threaded sleeve 12 are rotatably connected to a rotating plate 10. During the rotation of the threaded sleeve 12, the rotating plate 10 rotates in cooperation, which can improve the stability of the threaded sleeve 12. The rotating plate 10 is fixedly connected to the annular fixed sleeve 2. An expansion rod 3 is arranged inside the threaded sleeve 12. Through the expansion rod 3, the threaded extension and retraction are realized, so as to control the rotating rod 6 to realize the extension and pushing and retraction and pulling of the hand brake lever 7. One end of the expansion rod 3 is provided with an external thread 9, and the external thread 9 is in threaded cooperation with the threaded sleeve 12. One end of the expansion rod 3 is provided with a through hole 8. A rotating rod 6 is arranged on one side of the through hole 8. Both ends of the rotating rod 6 are rotatably matched with a second fixed shaft 15. The arc-shaped plate 16 on the outer side of one end of the second fixed shaft 15 is sleeved and rotatably matched with the through hole 8, and the arc-shaped plate 16 on the outer side of the second fixed shaft 15 at the other end is sleeved and rotatably matched with the hand brake lever 7, and thus the rotation adjustment control can be completed. The rotating rod 6 is rotatably matched with the second fixed shaft 15. Both ends of the rotating rod 6 are rotatably connected to the second fixed shaft 15. The outer side of the second fixed shaft 15 is fixedly connected with an arc-shaped plate 16. The arc-shaped plate 16 on the outside of the second fixed shaft 15 at one end is rotatably matched with the through hole 8, and the arc-shaped plate 16 on the outside of the second fixed shaft 15 at the other end is sleeved and matched with the hand brake lever 7. The bottom end of the hand brake lever 7 is rotatably connected to a first fixed shaft 4. The bottom end of the first fixed shaft 4 is fixedly connected to the mounting plate 5.

[0023] Both sides of one end of the expansion rod 3 are fixedly connected with sliders 14. Through the sliding cooperation between the sliders 14 and the sliding grooves 13, the stable position movement can be realized and the limiting effect can be achieved at the same time, so as to keep the expansion rod 3 from rotating. Both sides at the top inside the annular fixed sleeve 2 are provided with sliding grooves 13, and the sliders 14 are in sliding cooperation with the sliding grooves 13.

[0024] Working principle: When in use, first install the support base 1 above one end of the mounting plate 5. Then, both ends of the rotating rod 6 are rotationally matched with the second fixed shaft 15. The arc-shaped plate 16 on the outside of the second fixed shaft 15 at one end is rotationally sleeved with the through hole 8, and the arc-shaped plate 16 on the outside of the second fixed shaft 15 at the other end is rotationally sleeved with the handbrake lever 7, thus completing the rotational adjustment control. When the drive motor 11 at one end inside the annular fixed sleeve 2 drives, it can drive the threaded sleeve 12 to rotate. After rotation, it is threadedly matched with the external thread 9, thereby realizing the movement of the threaded position. Through this structure, the telescopic rod 3 is driven to realize the threaded extension and retraction, so as to control the rotating rod 6 to realize the extension and pushing and retraction to pull the handbrake lever 7, completing the work of releasing and tightening the handbrake of the handbrake lever 7. And during the rotation of the threaded sleeve 12, the rotating plate 10 is rotationally matched, which can improve the stability of the threaded sleeve 12.
