Problems solved by technology

[0002] At present, the lifting hydraulic cylinders used in reconnaissance vehicles are single-stage double-acting or single-stage single-acting hydraulic cylinders. The lifting stroke of the reconnaissance device of the reconnaissance vehicle is limited, and the space inside the reconnaissance vehicle is limited, so it is impossible to increase the length of the hydraulic cylinder. Obtaining a longer lift stroke limits the reconnaissance information and reconnaissance accuracy that the reconnaissance vehicle's reconnaissance device can obtain

Embodiment Construction

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0019] Such as figure 1 As shown, a double-stage double-acting lifting hydraulic cylinder for a reconnaissance vehicle includes a support base plate 1, a bottom cylinder 22 and an outer cylinder 21 of the oil cylinder. At the bottom, the oil cylinder outer cylinder 21 is vertically arranged, and its lower end is socketed and welded with the top of the bottom cylinder 22;

[0020] There is an oil passage A3 in the bottom cylinder 22, one end of the oil passage A3 is connected to the outside world, and the other end is connected to the inner cavity of the outer cylinder 21 of the oil cylinder. Rod 23, the anti-rotation rod 23 is covered with a primary cylinder bottom plate 5, the primary cylinder bottom plate 5 can s...

Abstract

The invention relates to a lifting hydraulic oil cylinder used on a scout car, particularly to a two-stage double-acting lifting hydraulic oil cylinder used on a scout car. The lifting hydraulic oil cylinder comprises a support base plate, a lower cylinder, an outer oil cylinder barrel, a second-stage cylinder barrel and a first-stage cylinder barrel. The lifting hydraulic oil cylinder has the benefits that a scout device of the scout car is mounted at the upper end of the second-stage cylinder barrel and the staged lifting of the first- and second-stage cylinder barrels is used to increase the lift stroke, without increasing an occupied area in the scout car, so that the information acquisition capability and scout accuracy of the scout device of the scout car can be enhanced.

Description

technical field [0001] The invention relates to a lifting hydraulic oil cylinder for a reconnaissance vehicle, in particular to a double-stage double-action lifting hydraulic oil cylinder for a reconnaissance vehicle. Background technique [0002] At present, the lifting hydraulic cylinders used in reconnaissance vehicles are single-stage double-acting or single-stage single-acting hydraulic cylinders. The lifting stroke of the reconnaissance device of the reconnaissance vehicle is limited, and the space inside the reconnaissance vehicle is limited, so it is impossible to increase the length of the hydraulic cylinder. Obtaining a longer lifting stroke limits the reconnaissance information and reconnaissance accuracy that the reconnaissance vehicle's reconnaissance device can obtain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-stage double-acting lifting hydraulic cylinder for scouting vehicles that i...
