Abstract

The invention discloses a durable hydraulic cylinder. The durable hydraulic cylinder comprises a shell, wherein a piston rod sliding along an inner cavity of the shell is arranged in the shell; the shell comprises a cylinder head, a cylinder barrel is detachably connected to the cylinder head, a cylinder tail is detachably connected to the cylinder barrel, and a cylinder body is detachably connected to the cylinder tail; the center lines of the inner cavities of the cylinder head, the cylinder barrel, the cylinder tail and the cylinder body coincide; one end, away from the cylinder tail, of the cylinder body is fixedly provided with a cylinder tail earring; the piston rod comprises a cylinder head earring and a front rod which is integrally arranged with the cylinder head earring, the front rod is detachably connected with a piston, the piston slides on the inner wall of the cylinder barrel in the direction of the center line of the piston, and the piston is integrally provided with arear rod; a front oil hole communicating with the inner cavity of the cylinder head is formed in the side face of the cylinder head, and the front oil hole communicates with the inner cavity of the cylinder barrel; a rear oil hole communicated with the inner cavity of the cylinder is formed in the side surface of the cylinder tail , and the rear oil hole communicates with the inner cavity of the cylinder barrel. The durable hydraulic cylinder has the effect of improving the structural strength of the joint of the cylinder head of the hydraulic cylinder and the front rod.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a durable hydraulic cylinder. Background technique [0002] With the continuous expansion of the new dry process cement production line, more and more grate coolers are used. The grate cooler is an important main equipment in the clinker burning system of a cement plant, mainly for cooling cement clinker , transportation; at the same time, it provides hot air for the rotary kiln and calciner, and is the main equipment for heat recovery in the firing system. [0003] In terms of the transmission type of the grate cooler, the hydraulic transmission has the advantages of stable transmission, convenient speed regulation, good reliability and high operating rate. [0004] The Chinese utility model patent with the authorized announcement number CN2861625Y discloses a grate cooler hydraulic transmission equipment, including a circulating cooling filter system, an oil tank, ...
