CNG ship loads and unloads emergent buffer of counter weight in system adaptation mechanism on bank

The utility model discloses a CNG ship loads and unloads emergent buffer of counter weight in system adaptation mechanism on bank, the device establish on the base of counter weight support, under the counter weight, and the key lies in: constitute buffer gear at buffer ferrule and sliding sleeve buffer spring within a definite time, sliding sleeve free end protrusion in the buffer ferrule and with the buffer spring cooperation in the buffer ferrule of the actuating lever front end of hydro -cylinder, spacing sliding sleeve and setting in the buffer ferrule including hydro -cylinder, setting in the structure. The beneficial effects of the utility model are that: adopt the buffer structure of spring - hydro -cylinder combined type, simple and practical is to the influence of equipment on whole counter weight support and the support in the time of can effectively alleviateing the counter weight tenesmus, be provided with reset spring and blotter, lightened the impact of counter weight to the hydro -cylinder.
