Wherein, driving piece 1 in this application is the engine for drive wheel 3 carries out work, and drive wheel 3 passes through belt 8 and drives air condition compressor 4 and move.

When the air conditioner compressor 4 works for a long time, the belt 8 connected to the driving wheel 3 and the air conditioner compressor 4 can gradually loosen and skid, and the problem that the belt 8 is insufficient in tension and even cannot work continuously occurs; at this time, it is necessary to tighten the belt 8 provided between the driving wheel 3 and the air conditioner compressor 4 so that the air conditioner compressor 4 can maintain a normal operation. For this reason, it is necessary to apply a driving force to the adjustment assembly provided on the mounting bracket 2, and at this time, the adjustment assembly gives a reverse driving force to the mounting bracket 2 so that the mounting bracket 2 moves in the height direction; at this time, the air conditioner compressor 4 also moves upwards along with the mounting bracket 2, the belt 8 arranged between the driving wheel 3 and the air conditioner compressor 4 is tensioned by adjusting the distance between the driving wheel 3 and the air conditioner compressor 4, and when the belt 8 is re-tensioned and the mounting bracket 2 rises to a proper height, the mounting bracket 2 stops moving to complete the tensioning of the belt 8. The additional tension wheel is canceled in the application, and the tension degree of the belt 8 is adjusted by only adopting the mounting bracket 2 with the adjustable height, so that the mounting structure of the engineering mechanical air conditioner is simplified and the production cost of the engineering mechanical air conditioner is reduced.

As shown in fig. 4, in the embodiment of the present application, the mounting bracket 2 includes a side plate 21, a top plate 22, and a cover plate 23.
