Description

Support body device and engine's tripod mounting structure

Technical Field

The utility model relates to the technical field of engines, in particular to a support body device and a mounting structure of a machine foot of an engine.

Background

The engine is used as a power source and needs to be mounted on a carrier, typically a ship, a generator set and the like for functioning. The connection between the engine and the carrier is generally divided into a rigid connection and a flexible connection according to different requirements, as shown in fig. 1, a rigid leg 410 between the engine 400 and the carrier 500 is a rigid connection without buffering and shock absorption, as shown in fig. 2, a flexible leg 600 is arranged between the engine 400 and the carrier 500 to play a role of buffering and shock absorption, and realize the flexible connection.

As shown in fig. 2 and 3, the rigid leg 410 of the engine 400 is generally cast integrally with the engine block 420 and is secured to the carrier through the leg mounting holes 411, while the flexible leg 600 is generally a separate component that is required to be mounted to the engine 400 by mating with other components.

In the prior art, when the engine 400 is flexibly connected with the carrier 500, an elastic supporting device 700 (vibration isolator) is installed at the connection position of the engine 400 and the carrier 500, as shown in fig. 4, which is a schematic structural diagram of the elastic supporting device 700, and mainly includes a main bolt 710, an upper seat 720, a rubber cone 730 and a base 740.

However, the elastic support device 700 is not directly mounted with the rigid tripod 410, but the elastic support device 700 is connected with the rigid tripod 410 through the support body 800. As shown in fig. 5 and 6, the support body 800 in the prior art includes a support base 810 and a support base pressing block 820, wherein the support base 810 is fixed to the rigid machine leg 410 by a bolt in cooperation with the support base pressing block 820, and the support base 810 and the support base pressing block 820 are also connected by a bolt, then the support base 810 is connected to the elastic supporting device 700, and finally the elastic supporting device 700 is fixed to the carrier 500.

However, after the rigid machine leg 410 is cast, the thickness dimension of the rigid machine leg 410 is not uniform, so that the consistency of the clamping connection between the supporting seat 810 and the supporting seat compressing block 820 on the rigid machine leg 410 is poor, the upper side and the lower side of the rigid machine leg 410 cannot be effectively compressed, and the rigid machine leg 410 and the supporting body 800 are in a loose state, so that the installation stability of the engine 400 and the carrier 500 is poor, and the problem that the engine 400 vibrates when the carrier 500 operates is caused, thereby interfering the normal operation of the machine and even causing the damage of parts.

Therefore, how to provide a support device to improve the stability of the mounting of the engine and the carrier is a technical problem that needs to be solved by those skilled in the art.
