RU611U1 - Hydraulic drive lifting device - Google Patents

Abstract

1. The hydraulic drive of the lifting device, comprising a pumping station, a power cylinder, the rodless cavity of which is connected to the pumping station, and the rod cylinder through a channel with a check valve is connected to the output of the working chamber of the plunger pump of the working fluid leakage compensation unit, the input of which is connected to the pumping station, characterized the fact that the working chamber and the channel with a non-return valve are made in the piston of the power cylinder, and the pump plunger is fixed in the rodless cavity and has a length less than the piston stroke. 2. The drive according to claim 1, characterized in that the plunger is mounted on the cover of the power cylinder.

At the same time, the working fluid through the channel 12 enters the gutter cavity in the power chamber 2, compensating for leaks. In the case of overcrowding of the cavity in the working rail), its excess merges through the overflow valve (not shown in the drawing)

The proposed drive allows, due to the location of the Ш1зщжзрный pump in smd 1dil1 ddr, to leave the whole line (of the drive to increase the reliability of its operation and reduce the cost of maintenance so that it is designed in two ways without additional adjustment).
