VESSEL BLOCK LIFT Russian patent published in 2022 - IPC B66B9/04 

FIELD: handling equipment.

SUBSTANCE: invention relates to the field of handling equipment. Vessel block lift contains a power frame mounted on retractable wheels, a vertical hydraulic cylinder, two horizontal double-acting piston hydraulic cylinders, a pumping unit with hydraulic equipment and a control panel for hydraulic motors. The cylinder consists of a body with top and bottom covers and a central hole. A power piston with a rod is installed in the hole. The bottom cover of the hydraulic cylinder rests on a flat surface with an anti-friction coating of the power frame. An adapter plate with a spherical insert is installed on the rod to interact with the vessel block. The body of each of the horizontal hydraulic cylinders crossed at a right angle is pivotally connected to the power frame, and the rod is pivotally connected to the vertical hydraulic cylinder body. The power piston rod of the vertical hydraulic cylinder is threaded and a nut is screwed on it between the top cover and the adapter plate. On the outer surface of the nut, a gear engagement is made. The nut is driven by a hydraulic motor. The hydraulic motor is mounted on the adapter plate by means of an intermediate shaft connected to the hydraulic motor shaft. The intermediate shaft is installed with the possibility of axial movement in the guide bracket. The bracket is connected to the body of the vertical hydraulic cylinder, in which an even number of holes are made at equal distances along the circumference. The axes of the holes are parallel to the axis of the central hole. Pistons with rods of return hydraulic cylinders are installed in two diametrically located holes from these holes, and cylindrical guide rods are installed in the remaining holes. The rods are rigidly connected to the adapter plate. The connection of all rods with the adapter plate is made movable without a gap in the axial direction of the rods.

EFFECT: increased reliability of the vessel block lift and safety of its operation.
