Description

Fire grate hydraulic cylinder with earring connecting structure Technical Field The disclosure relates to the technical field of fire grate hydraulic cylinders, in particular to a fire grate hydraulic cylinder with an earring connecting structure. Background The fire grate hydraulic cylinder is a core executing mechanism of heat energy equipment such as a garbage incinerator, a biomass boiler and the like, and the actions such as lifting and pushing of the fire grate are realized through hydraulic driving, so that the combustion efficiency and the pollutant emission control are directly affected. The fire grate hydraulic cylinder generally comprises an earring, a cylinder body and a piston rod arranged on the cylinder body, wherein the end part of the piston rod extending out of the cylinder body is connected with the earring. In the conventional technology, the connection mode of the piston rod and the earring is mostly threaded connection, namely, the piston rod and the earring are connected through internal and external threads which are matched with each other. The screw connection mainly has the following defects that because the fire grate hydraulic cylinder is in a severe environment and is mainly used for fire grate systems of garbage incinerators or coal-fired boilers, high temperature, high pressure, vibration and dust can be generated when the equipment is operated, when the hydraulic cylinder needs to be replaced for maintenance each time, the screw connection is often blocked due to corrosion, abrasion and dust pollution, and broken disassembly, namely destructive disassembly, is needed in most cases, so that the maintenance labor cost and the replacement and use cost of spare parts are obviously increased.
