These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-2 As shown, a pneumatic remote control structure for shifting gears includes a gearbox 1, a fixed frame 2, and an automatic shifting assembly 3 placed on the fixed frame 2.

[0023] The fixed frame 2 is composed of a first fixed frame 201, a second fixed frame 202, and a U-shaped fixed frame 203. The upper part of the first fixed frame 201 is provided with a through hole 2011. The gearbox 1 extends out a shift shaft 4 and leads out from the through hole 2011. The shift shaft 4, which leads out from the through hole 2011, is connected to the first side plate 5, and the first side plate 5 is connected to the second side plate 6.

[0024] The automatic shifting assembly 3 consists of an axial drive cylinder 301 and a rotary drive cylinder 302. The axial drive cylinder 301 is placed between the bottom of the U-shaped fixed frame 203 and the upper end of the second side plate 6. One end of the rotary drive cylinder 302 is hinged to the lower end of the second side plate 6, and the other end is hinged to the bracket 7 and then connected to the second fixed frame 202.

[0025] like Figure 2As shown, the first fixed frame 201 has extension plates 2012 on both sides, and the extension plates 2012 are connected to the gearbox 1 housing by bolts; the first fixed frame 201 and the second fixed frame 202 are perpendicularly connected, and the first fixed frame and the second fixed frame serve as the mounting frame for the automatic shifting component, ensuring that it can be stably fixed on the gearbox housing.

[0026] like Figure 2 As shown, a fixing ring 8 is provided above the first side plate 5. The fixing ring 8 has an opening on its side and bolt fixing parts 801 are provided at both openings. The shift shaft 4 is placed inside the fixing ring and locked with bolts. The opening and closing fixing ring can effectively adapt to shift shafts of different diameters, and can also achieve quick disassembly and assembly, improving efficiency.

[0027] like Figure 2 As shown, the axial drive cylinder 301 is fixedly connected to the upper part of the second side plate 6, and the other end is connected to a guide post 3011. The guide post 3011 passes through the frame through hole on the bottom of the U-shaped fixed frame 203 and is provided with a fixing cap 30111. A limit nut 9 is provided on the guide post 3011 on the U-shaped fixed frame 203. The bottom of the U-shaped fixed frame is placed between the limit nut and the fixing cap. There is a large gap between the limit thread and the fixing cap. The gap is greater than the thickness of the bottom of the U-shaped fixed frame. At the same time, the diameter of the guide post is smaller than the diameter of the frame through hole. That is, the axial drive cylinder can realize multi-directional angle transformation, providing sufficient space for the axial drive cylinder to drive the reversing shaft.

[0028] like Figure 2 As shown, the rotary drive cylinder 302 is connected to the second side plate 6 and the bracket 7 by ball joints. Through the ball joints, the rotary drive cylinder can achieve multi-dimensional angle transformation and adaptive adjustment when it cooperates with the axial drive cylinder.

[0029] like Figure 2 As shown, the first side plate 5 and the second side plate 6 are fixedly connected by a double bolt group to ensure the stability of the connection between the two side plates and prevent loosening.

[0030] like Figure 2 As shown, the rotary drive cylinder 302 and the axial drive cylinder 301 are electrically connected to the external control system. The cylinders can be remotely controlled through the external control system, resulting in a higher degree of automation.

[0031] The working principle of this utility model is explained as follows: In use, the shift shaft is axially moved and rotated by a rotary drive cylinder, which enables remote control of the shift shaft.

[0032] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
