And hoisting rings 2 are integrally cast on both outer walls of the engine cylinder block main body 1. And a hoisting hole 3 is integrally formed on the inner wall of the hoisting ring 2. And the hoisting ring 2 is fixedly connected with a lifting connecting piece through the hoisting hole 3;

[0026] By spraying an iron-based coating inside the cylinder block of the engine cylinder block main body 1, its wear resistance is improved. The engine cylinder block main body 1 is made of aluminum alloy. By providing the hoisting hole 3, when it is necessary to lift or install the engine cylinder block main body 1, it is convenient to install and fix the lifting connecting piece. After the lifting connecting piece and the hoisting ring 2 are fixed, the stability of the engine cylinder block main body 1 during hoisting is ensured, and it is avoided that the engine cylinder block main body 1 falls due to instability during hoisting, resulting in potential safety hazards.

[0027] Furthermore, the lifting connecting piece includes a pin 8 and a guiding ring 9. The pin 8 and the guiding ring 9 are slidably connected. And a plurality of pins 8 are synchronously driven by a driving mechanism. And a support ring 4 is fixed at one end of the driving mechanism;

[0028] By arranging a driving mechanism, a plurality of pins 8 can be driven to move synchronously along the guiding ring 9. The number of pins 8 corresponds to the number of lifting holes 3. In this embodiment, the number of pins 8 on each lifting connecting piece is three groups. After the plurality of pins 8 move, they are inserted into the inner wall of the lifting hole 3, so as to realize the fixation between the guiding ring 9 and the lifting ring 2. When lifting, the hook of the lifting device is hooked on the supporting ring 4, so as to facilitate the lifting of the engine cylinder block main body 1.
