Problems solved by technology

Many existing hydraulic actuators must be immersed in water as a whole according to their work requirements. During the movement, more or less external liquid will be brought into the interior of the hydraulic actuator, and enter the hydraulic pressure with the oil. The pipeline reaches the hydraulic oil tank of the hydraulic system, thereby polluting the entire hydraulic system and causing serious consequences

Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0043] This embodiment provides a volume-adjustable isolation oil cylinder, see attached figure 1 , including: cylinder bottom 1, first proximity switch 2, second proximity switch 11, support sleeve 3, first induction magnet 4, second induction magnet 10, first spring 5, push rod 6, second spring 7, cylinder Cylinder 8, piston 9, nut 12, guide sleeve 13, end cover 14, thrust bearing 15 and adjusting screw 16;

[0044] The cylinder 8 is a cylinder with two ends open, and two oil ports communicating with the inner cavity are respectively processed on the circumferential surface of the two ends, which are oil port A and oil port B respectively;

[0045] An inner hole is processed in the cylinder bottom 1;

[0046] The supporting sleeve 3 is a cylindrical body with an opening at one end and a through hole processed at the other end, and radial oil passing ho...

Abstract

The invention discloses a volume-adjustable isolation oil cylinder, and belongs to the technical field of hydraulic systems. The oil cylinder comprises a cylinder bottom, a first in-place induction mechanism, a second in-place induction mechanism, a supporting sleeve, a second spring, a cylinder barrel, a piston, a volume adjusting assembly and an end cover; the cylinder bottom is arranged at oneend of the cylinder barrel, the volume adjusting assembly and the end cover are arranged at the other end of the cylinder barrel, the supporting sleeve is located in the cylinder barrel, the piston isarranged in the cylinder barrel, the supporting sleeve is sleeved with the second spring, the first in-place induction mechanism is arranged on the cylinder bottom and in the supporting sleeve, whenthe piston moves to be in place in the cylinder bottom direction, the first in-place induction mechanism is triggered, the second in-place induction mechanism is arranged on the volume adjusting assembly and the piston, and when the piston moves to be in place in the direction of the end cover, the second in-place induction mechanism is triggered; according to the oil cylinder, hydraulic oil in ahydraulic pipeline of an in-cabin hydraulic system and hydraulic oil in a hydraulic pipeline of an out-cabin hydraulic execution part are isolated, and the exterior liquid is prevented from being brought into a hydraulic oil tank of the hydraulic system.

Description

technical field [0001] The invention belongs to the technical field of hydraulic systems, and in particular relates to an isolation oil cylinder with adjustable volume. Background technique [0002] The hydraulic system in the cabin is connected with the hydraulic actuator components outside the cabin through hydraulic pipelines, and the hydraulic system controls the work of the hydraulic actuator components through the hydraulic pipelines. Many existing hydraulic actuators must be immersed in water as a whole according to their work requirements. During the movement, more or less external liquid will be brought into the interior of the hydraulic actuator, and enter the hydraulic pressure with the oil. The pipeline reaches the hydraulic oil tank of the hydraulic system, thereby polluting the entire hydraulic system and causing serious consequences. Contents of the invention [0003] In view of this, the present invention provides a volume-adjustable isolation oil cylinder...
