The invention discloses a hydraulic oil cylinder with a built-in stacked oil pipe structure, which comprises a rod head, a piston rod, an end cover, a cylinder head, a cylinder barrel, a piston, a plug, a central bright pipe, an oil pipe, a piston and a cylinder bottom. The cylinder head is coaxially welded at the left end of the cylinder barrel, the end cover is coaxially installed in the cylinder head, the rod head is welded at the left end of the piston rod, and an oil inlet and outlet are opened on the rod head. The plug is welded on the right end of the piston rod, the piston rod is hollow, the piston is fixed on the plug, the first layer of oil pipe is welded inside the piston rod, the central bright tube is suspended and fixed inside the first layer of oil pipe, and two semicircular rings are used to fixed on the cylinder bottom. The bottom of the cylinder is welded on the right end of the cylinder barrel, and there are two oil holes on the bottom of the cylinder, and a hole E is drilled on the cylinder barrel. The hydraulic oil cylinder with a built-in stacked oil pipe structure of the present invention has the advantages of being able to solve the problems of complex shape of the existing oil cylinder, easy installation deviation under the requirement of narrow and compact installation space, and relatively free installation of the whole machine.
Description
technical field [0001] The invention relates to a hydraulic oil cylinder, in particular to a hydraulic oil cylinder with a built-in stacked oil pipe structure inside the oil cylinder. Background technique [0002] Now the truck-mounted crane series telescopic arm oil cylinders in the market, for the whole system, it is required to have two associated hydraulic cylinders for coordinated movement, so that the boom of the truck-mounted crane can do free telescopic movement, then for the two The associated hydraulic cylinders must have the same inlet and outlet ports, that is, when the hydraulic oil of one cylinder enters the rod cavity through the oil inlet, the hydraulic oil of the other cylinder is required to be connected to the rod cavity through a sequence valve. , through the sequence valve, the associated movement of the two oil cylinders is realized. Then, for the associated oil cylinders mentioned in the present invention, on the one hand, it can meet the requirement ...
