Abstract

The invention belongs to the technical field of engineering machinery, and provides an assembling device for a multi-stage cylinder. The assembling device is simple in structure, and convenient and reliable to use. According to the assembling device for the multi-stage cylinder, a stand column (2) is installed on a base (1), a installation base (4) is installed at the upper end of the stand column(2), a support base (3) is located right below the installation base (4), and is installed above the base (1), a ear shaft connecting rod (6), a connecting rod (7) and a screw rod (8) form a pressingmechanism, the pressing mechanism is installed in trunnions of a first section cylinder barrel (9), and a screw rod (8) is in contact with the upper surface of a hoisting device (16) to press down the hoisting device (16).

Description

technical field [0001] The invention belongs to the technical field of engineering machinery and specifically provides an assembly device for a multi-stage cylinder of a dump truck. Background technique [0002] Dump truck lift cylinders are generally single-acting multi-stage cylinders with a thin-walled sleeve structure. Multi-stage cylinders are generally assembled by multi-section sleeves, the outer sleeve is equivalent to the cylinder barrel of the inner sleeve, and the inner sleeve is equivalent to the piston rod of the outer sleeve. Wear-resisting, guide rings, seals and retaining spring structures for cylinder movement limitation are installed between the two sleeves. Although the multi-stage cylinder has a simple structure and few components, its assembly is not easy. The main reason is that the length of the cylinder is longer and the diameter is larger, and the outer surface of the cylinder is the sealing surface in contact with the sealing ring, which is easy t...
