Detailed Description of the Preferred Embodiments

[0022] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0023] As Figure 1 shown, in the technical solution of the present utility model, a general test base for diesel engines is provided, including:

[0024] A general base 1, which is a platform structure and includes upper and lower surfaces.

[0025] Multiple diesel engine fixing mechanisms, one end of the diesel engine fixing mechanism is detachably connected to the upper surface of the general base 1, and the other end is connected to the corresponding component of the diesel engine, fixing the diesel engine on the general base 1.

[0026] The diesel engine fixing mechanism is manufactured according to the diesel engine model and the corresponding components, and one diesel engine fixing mechanism corresponds to one type of diesel engine.

[0027] The general base 1 is a double-layer steel plate structure, and multiple vertical strengthening structures 2 are arranged inside.

[0028] As Figure 1 shown, in an embodiment of the present utility model, various bolt connection holes are provided on the upper surface of the general base 1 and the end surface of the diesel engine fixing mechanism, and the general base 1 and multiple types of diesel engine fixing mechanisms are connected by bolts.

[0029] In an embodiment of the present utility model, a slot structure is provided on the upper surface of the general base 1, and a plug is provided on the end surface of the diesel engine fixing mechanism. The diesel engine fixing mechanism is fixed on the general base 1 through the plug.

[0030] As Figure 2 shown, in an embodiment of the present utility model, when the diesel engine to be tested is a 16-cylinder diesel engine, the general test base includes the lower general base 1 and the fixing mechanism on the upper layer of the general base 1. Among them, the fixing mechanism mainly serves as the support for the "16-cylinder diesel engine", specifically including the flywheel belt vibration isolator fixing mechanism 3, the free end vibration isolator fixing mechanism 4 and the limiter fixing mechanism 5. When conducting the test on the 16-cylinder diesel engine 6, the 16-cylinder diesel engine 6 is fixed on the general base 1 through the flywheel belt vibration isolator fixing mechanism 3, the free end vibration isolator fixing mechanism 4 and the limiter fixing mechanism 5, and the hydraulic dynamometer 9 is connected to the 16-cylinder diesel engine 6 through the elastic coupling 8, as Figure 3 shown. As Figure 4 shown, when the diesel engine to be tested is an 8-cylinder diesel engine, the fixing mechanism mainly serves as the support for the "8-cylinder diesel engine" 7, specifically including the flywheel belt vibration isolator fixing mechanism 3 and the free end vibration isolator fixing mechanism 4. When conducting the test on the 8-cylinder diesel engine 7, the 8-cylinder diesel engine 7 is fixed on the general base 1 through the flywheel belt vibration isolator fixing mechanism 3 and the free end vibration isolator fixing mechanism 4, and the hydraulic dynamometer 9 is connected to the 8-cylinder diesel engine 7 through the elastic coupling 8, as Figure 5As shown. In this embodiment, by replacing the fixing mechanism on the upper layer of the general base 1, the installation work of the "16-cylinder diesel engine" or the "8-cylinder diesel engine" can be completed on the same general base 1. On the basis of using the existing hydraulic dynamometer and elastic coupling, the test requirements of the "8-cylinder diesel engine" and the "16-cylinder diesel engine" are met. The general test base of this embodiment can meet the installation and test requirements of the "8-cylinder diesel engine" and the "16-cylinder diesel engine" by replacing the upper fixing structure without changing the elastic coupling, the hydraulic dynamometer (there is no axial eccentricity and no repeated alignment is required), and the general base 1. It has high accuracy, reasonably utilizes the test resources, saves the test cost, and shortens the test cycle.

[0031] Taking the 16-cylinder diesel engine and the 8-cylinder diesel engine in the above embodiment as examples, although the foot structures of these two types of diesel engines are significantly different, their shafting output structures are the same, and they are consistent in shafting connection and alignment. Therefore, both of them use the same hydraulic dynamometer as the power-consuming device and are connected to the shafting of the hydraulic dynamometer 9 through the same elastic coupling 8. There is no axial eccentricity problem, the axial alignment work is reduced, the accuracy is high, and it has a certain economy.

[0032] Based on the same general base 1, the present utility model designs two types of upper-layer detachable fixing mechanisms for the foot structures of multiple types of diesel engines. By replacing the upper-layer detachable fixing mechanism, the installation, alignment, and test of the diesel engine can be completed.

[0033] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
