Technical Field

[0001] The invention relates to the technical field of connection and installation, and in particular to a connection structure for flipping and repairing a non-road engine. Background Art

[0002] Non-road engines generally refer to engines that do not power vehicles on public roads. These engines are used in various non-road applications, such as construction machinery, agricultural machinery, boats, generators, aircraft, etc. Their design and operating characteristics are different from engines used on public roads because they operate in specific non-road environments and may require different performance standards and durability requirements.

[0003] Non-road engines need to be repaired after a fault occurs. When non-road engines are repaired for internal component faults such as piston connecting rod burnout, connecting rod pin wear, etc., the engine needs to be flipped to about 90° without disassembling the engine. However, because the relevant model is a flywheel plate model and there are no related transition connection parts, the engine cannot be placed on a tooling flip trolley for flip repair. Therefore, when such a fault occurs, the engine must be dismantled. First, a large amount of workload is increased, which is a waste of operation. Second, the engine output delivery cycle is affected. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a connection structure for non-road engine flipping and repairing in view of the above-mentioned deficiencies in the prior art, which can solve the problem of flipping and repairing internal components of non-road engines, optimize the repair operation, shorten the repair time, and has the characteristics of wide applicability and strong practicality.
