In this embodiment, the cooler body 1 can blow air to the oil pipeline 100 in the installation box, so the air cooler suitable for the gear box can cool down the lubricating oil in the installation box, so as to ensure the normal operation of the installation box; the connecting bottom beam 21 is fixedly connected to the installation box, and since the cooler body 1 is arranged on the mounting seat 22, and the mounting seat 22 is arranged on the connecting bottom beam 21, the cooler body 1 is connected to the installation box; the installation box is provided with a lifting ear, and since the mounting seat 22 can move on the connecting bottom beam 21 along the first direction so that the cooler body 1 on the mounting seat 22 can vertically avoid the lifting ear, the air cooler installation suitable for the gear box After completion, it is possible to avoid blocking the lifting ears, and the overall lifting of the installation box can be achieved vertically without the aid of other external devices. The operation is simple and practical. Since the cooler body 1 can move on the mounting seat 22 along the second direction, a maintenance space is formed between the cooler body 1 and the installation box, which facilitates the later maintenance and disassembly of the cooler body 1 and the oil pipeline 100. At the same time, since the cooler body 1 can move relative to the installation box along the first direction and the second direction respectively, the oil pipeline 100 in the installation boxes of different sizes and structures can be cooled, thereby expanding the scope of application of the air cooler suitable for the gear box and improving its practicality. Specifically, the cooler body 1 is an air-cooled cooler device commonly used in this field, and the oil pipeline 100 passes through the air outlet end of the cooler body 1; the first direction is the horizontal direction of the installation box, and the installation box is provided with a lifting lug for connecting to the lifting equipment.

In this embodiment, the first oblong hole extends along the first direction, and the rod portion of the first bolt 31 passes through the first through hole and the first oblong hole and is connected to the first nut 32. The head of the first bolt 31 abuts against the connecting bottom beam 21, and the first nut 32 abuts against the mounting seat 22, so that the mounting seat 22 abuts against the connecting bottom beam 21, thereby locking the mounting seat 22 and the connecting bottom beam 21; when it is necessary to move the mounting seat 22 along the first direction, the staff loosens the first nut 32 on the first bolt 31 in the reverse direction, but does not unscrew the first nut 32 from the first bolt 31. At this time, the mounting seat 22 is detached from the connecting bottom beam 21 is firmly pressed against the mounting seat 22, so the mounting seat 22 can move relative to the connecting bottom beam 21. At the same time, because the first bolt 31 is still inserted into the first oblong hole of the mounting seat 22, the mounting seat 22 can and can only move along the first direction under the limiting action of the first bolt 31; after the mounting seat 22 is moved to the specified position, the staff tightens the first nut 32 in the forward direction to make the first nut 32 press against the mounting seat 22, so that the mounting seat 22 presses against the connecting bottom beam 21, thereby fixing the position of the mounting seat 22 again and preventing the cooler body 1 from shaking during the operation of the gear box.

[0037] Specifically, Figure 1 As shown, the mounting seat 22 includes a diagonal bracing beam 221, a bearing frame 222 and a cross beam 223.

[0038] Specifically, Figure 1As shown, the support frame 222 and the diagonal bracing beam 221 are both connected to the connecting bottom beam 21 through the first limiting assembly 3. In this embodiment, the first limiting assembly 3 is provided on the end of the diagonal bracing beam 221 and the end of the support frame 222, so the diagonal bracing beam 221 and the support frame 222 are respectively connected to the connecting bottom beam 21 through the first limiting assembly 3, thereby improving the stability of the mounting seat 22 when moving along the first direction, and also further enhancing the reliability of the connection between the mounting seat 22 and the connecting bottom beam 21.

[0039] Specifically, Figure 1 and Figure 3 As shown, a second limiting assembly 4 is arranged between the cooler body 1 and the mounting seat 22, and the second limiting assembly 4 includes a matching second bolt 41 and a second nut 42. A second through hole is opened on the mounting seat 22, and a second oblong hole extending along the second direction is opened on the cooler body 1 corresponding to the second through hole. The second bolt 41 passes through the second through hole and the second oblong hole in sequence and is connected to the second nut 42, and the second nut 42 rests on the cooler body 1.

The head of the second bolt 41 abuts against the support frame 222 of the mounting seat 22, and the second nut 42 abuts against the cooler body 1, so that the cooler body 1 is pressed against the support frame 222, thereby locking the cooler body 1 and the support frame 222; when it is necessary to move the cooler body 1 along the second direction, the staff loosens the second nut 42 on the second bolt 41 in the reverse direction, but does not unscrew the second nut 42 from the second bolt 41. At this time, the cooler body 1 is detached from the support frame The bracket 222 is in a state of being pressed against the support frame 222, so the cooler body 1 can move relative to the mounting seat 22; at the same time, because the second bolt 41 is still inserted into the second oblong hole of the cooler body 1, the cooler body 1 can and can only move along the second direction under the limiting action of the second bolt 41; after the cooler body 1 is moved to the specified position, the staff tightens the second nut 42 in the forward direction, and the second nut 42 is pressed against the cooler body 1, so that the cooler body 1 is pressed against the support frame 222, thereby fixing the position of the cooler body 1 again and preventing the cooler body 1 from shaking during the operation of the gearbox.

In this embodiment, a plurality of first rollers 224 are rotatably provided on the mounting seat 22, and the first rollers 224 are rollingly matched with the connecting bottom beam 21. When the mounting seat 22 needs to be moved along the first direction, the staff first reversely loosens the first nut 32 on the first bolt 31, and after the mounting seat 22 is separated from the contact with the connecting bottom beam 21, the staff pushes the mounting seat 22 along the first direction; since the mounting seat 22 is rollingly provided on the connecting bottom beam 21 through the first rollers 224, the resistance during the movement of the mounting seat 22 is greatly reduced, which saves time and effort and is convenient to operate.

[0041] Specifically, Figure 1 and Figure 2 As shown, a first elastic member 225 is provided between the first roller 224 and the mounting seat 22. In this embodiment, a wheel frame for mounting the first roller 224 is provided on the ends of the diagonal support beam 221 and the carrier frame 222 close to the connecting bottom beam 21, and the first roller 224 is rotatably arranged on the wheel frame, and the wheel frame is connected to the mounting seat 22 through the first elastic member 225; specifically, the first elastic member 225 is a compression spring, and when the first nut 32 is loosened, the mounting seat 22 will automatically move away from the connecting bottom beam 21 under the elastic force of the first elastic member 225, so as to prevent the friction resistance between the mounting seat 22 and the connecting bottom beam 21, thereby greatly facilitating the subsequent pushing of the mounting seat 22.

[0042] Furthermore, if Figure 1 and Figure 3 As shown, the cooler body 1 is rotatably provided with a second roller 11, and the second roller 11 is rollingly matched with the mounting seat 22.
