The invention relates to a limiting structure and a double-outlet-rod oil cylinder. The limiting structure comprises a connecting cylinder, two limiting rings and a limiting sliding block. A through sliding groove is formed in the connecting cylinder, the extending direction of the sliding groove is consistent with the extending direction of the connecting cylinder, and the two limiting rings are movably arranged on the periphery of the connecting cylinder in a sleeving mode and can be fixedly connected with the connecting cylinder. The limiting sliding block is arranged in the connecting cylinder, the two ends, in the diameter direction, of the limiting block are slidably connected into the sliding groove, the limiting sliding block is located between the two limiting rings and can slide between the two limiting rings, and the limiting rings are moved so as to limit the moving distance of the limiting sliding block. The connecting cylinder is connected to the end, close to an auxiliary piston rod, of the oil cylinder through a flange, the auxiliary piston rod penetrates into the connecting cylinder, and the end portion is connected with the limiting sliding block. The auxiliary piston rod pushes the limiting sliding block to move between the two limiting rings, limiting of the auxiliary piston rod of the double-outlet-rod oil cylinder is achieved through limiting of the limiting sliding block, and then the effective stroke of the auxiliary piston rod is limited.
Description
technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a position-limiting structure and a double-rod cylinder. Background technique [0002] As an important type of oil cylinder, the double-rod cylinder is mainly used to realize the constant-velocity reciprocating motion at both ends of the piston rod of the double-rod cylinder. Double-rod cylinders are generally equipped with a limit device on the cylinder to limit the stroke of the piston rod. [0003] However, the existing double-rod oil cylinder basically relies on the guide sleeves at both ends to limit the position, and needs continuous liquid supply to ensure that there is pressure in the pressure chamber before it can work normally. There is always pressure in the pressure chamber, which poses a great test to the seal. , once the seal fails, the cylinder will not work properly. The guide sleeve is mostly fixed on the cylinder barrel by thread connection or bolt...
