[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0022] Referring to Figures 1-5 , an embodiment of a shot peening device for the outer wall of oilfield drill pipes of the present utility model includes: a base 1. Two installation tables 2 and a processing box 15 are fixedly connected to the upper surface of the base 1. The left and right surfaces of the processing box 15 are in close contact with the two installation tables 2 respectively. A positioning cover 10 and multiple support members 13 are arranged inside the processing box 15. The positioning cover 10 is rotatably connected to the left wall of the processing box 15, and the support members 13 are fixedly connected to the bottom wall of the processing box 15. When using the device, the inner walls of the support members 13 and the positioning cover 10 are in close contact with the drill pipe. The above devices cooperate with each other to form the basic components that restrict the movement of the oilfield drill pipe. Among them, the support member 13 is composed of a vertical rod and a round roller. Two support members 13 facing each other front and back are a group. The drill pipe is supported by the gap between each group of support members 13. The round roller is rotatably connected to the vertical rod. A layer of cotton pad is pasted on the surface of the round pipe to reduce the wear effect between the support member 13 and the drill pipe.

[0023] Inside the positioning cover 10, a reinforcement component 11 is fixedly connected. The reinforcement component 11 consists of a fixed ring 16 and a surrounding belt 17. The fixed ring 16 and the surrounding belt 17 are respectively fixedly connected to the front and lower inner walls of the positioning cover 10. The reinforcement component 11 ensures that the drill pipe is driven to rotate by the positioning cover 10 by means of the surrounding belt 17 surrounding and reinforcing the drill pipe. On the upper surface of the installation platform 2 at the left end, a servo motor 12 is fixedly connected. The rotating end of the servo motor 12 penetrates the left wall of the processing box 15 and is fixedly connected to the positioning cover 10. The servo motor 12 provides convenience for rotating the positioning cover 10.

[0024] On the upper surface of the installation platform 2, an installation frame 3 is fixedly connected. At the upper end of the installation frame 3, a slide rail 4 is fixedly connected. Inside the slide rail 4, a slider 5 is slidably connected. At the right end of the upper surface of the installation frame 3, a second automatic telescopic rod 14 is fixedly connected. The left end of the second automatic telescopic rod 14 is fixedly connected to the right surface of the slider 5. On the lower surface of the slider 5, a lifting member 20 is fixedly connected. The lifting member 20 consists of a first automatic telescopic rod 6 and a mounting plate 8. The first automatic telescopic rod 6 is fixedly connected to the mounting plate 8. At the lower end of the lifting member 20, a shot peening mechanism 7 and two positioning rings 9 are provided. The positioning rings 9 are slidably connected to the lifting member 20. The above devices cooperate with each other to form an auxiliary limiting mechanism that cooperates with the support member 13 to ensure sufficient stability of the drill pipe during the shot peening process. Among them, the second automatic telescopic rod 14 improves the convenience of moving the slider 5 and changing the position of the shot peening mechanism 7. Among them, the shot peening mechanism 7 is a common shot peening device for performing shot peening work on drill pipes in real life.

[0025] On the lower surface of the mounting plate 8, two side plates 18 are fixedly connected. The side plates 18 are located at the left and right ends of the nozzle of the shot peening mechanism 7. The side plates 18 limit the movement range of the positioning rings 9 to prevent the positioning rings 9 from being too close to the nozzle of the shot peening mechanism 7 and affecting the effect of the shot peening mechanism 7. On the side of the side plate 18 away from the shot peening mechanism 7, a spring 19 is fixedly connected. The end of the spring 19 away from the side plate 18 is fixedly connected to the positioning ring 9. The spring 19 ensures that the displaced positioning ring 9 automatically resets.

[0026] Working principle: When using the device, first place one end of the drill pipe inside the positioning cover 10, then place the drill pipe flat in the gap of the support member 13, and then use the reinforcement component 11 to improve the stability of the drill pipe inside the positioning cover 10. At this time, use the lifting member 20 to press the positioning ring 9 against the drill pipe. Since the positioning ring 9 is directly at both ends of the shot peening mechanism 7, it further ensures the accuracy when the shot peening mechanism 7 acts. The second automatic telescopic rod 14 drives the shot peening mechanism 7 to translate left and right through the slider 5. When the positioning ring 9 is blocked during the translation process, it moves in the direction closer to the shot peening mechanism 7 to avoid the positioning ring 9 affecting the effect of the shot peening mechanism 7. Without the restriction, the spring 19 extends to drive the positioning ring 9 to reset.

[0027] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
