The outer frame 2 and the transportation fixing support 3 can be of an integral structure, can be detachably connected through bolts, pins and the like, and can also be detachably connected through welding, bonding and other modes.

Referring to fig. 2-4, the first limit pin 6 is used to connect the engine 1 and the transportation fixing bracket 3, the upper end surface of the transportation fixing bracket 3 is lower than the bottom surface of the positioning fixing hole of the engine 1, and the movable range of the engine 1 is defined between the upper end surface of the transportation fixing bracket 3 and the bottom surface of the positioning fixing hole of the engine 1.

For example, when the engine 1 is subjected to a vertically downward pressure, the engine 1 moves downward relative to the transport fixing bracket 3, so that the distance from the bottom surface of the positioning fixing hole to the upper end surface of the transport fixing bracket 3 is shortened, and therefore, the damping assembly located between the engine 1 and the outer frame 2/transport fixing bracket 3 is compressed to generate a vertically upward reaction force, thereby driving the engine 1 to move upward relative to the transport fixing bracket 3 to damp the vibration applied to the engine 1 through the damping assembly.

In order to avoid the horizontal shaking of the first limit pin 6 in the positioning fixing hole of the engine 1, the outer diameter of the waist-shaped section of the first limit pin 6 is generally set to be the same as the inner diameter of the positioning fixing hole, so as to limit the engine 1 to move up and down along the length direction of the first limit pin 6, thereby reducing the impact on the engine 1 under the conditions of vibration, collision and the like.

First spacer pin 6 adopts the rigid material preparation, and is preferred, can set up first spacer pin 6 into the stainless steel spacer pin, and surface strength is higher, difficult wearing and tearing are inefficacy. Of course, it may be made of iron, copper, duralumin, or other common hard materials, or even high-strength plastic materials, as long as the strength of the material meets the strength requirement of the first stopper pin 6.

In this embodiment, the transportation fixing bracket 3 is connected with the engine 1 through the first limit pin 6, and because the length of the waist-shaped section of the first limit pin 6 is greater than the positioning fixing hole of the engine 1, on the premise that the connection of the engine 1, the transportation fixing bracket 3 and the outer frame 2 is ensured, the engine 1 can move in the height direction relative to the transportation fixing bracket 3, and a certain movement margin is reserved.
