Abstract

The invention discloses a hydraulic cylinder device, which comprises a cylinder barrel, a piston, a piston rod and a differential pressure electric signal generating device, wherein two ends of a piston movement simulated control zone of the cylinder barrel respectively form signal oil holes, and the differential pressure electric signal generating device comprises a differential pressure valve, an oil draining device and a pressure sensor. When the piston does not enter the piston movement simulated control zone, a valve core closes the differential pressure valve under the propping of an elastic component, so that an executing cavity and a differential pressure detection cavity of the differential pressure valve are separated from each other; and when the piston enters the piston movement simulated control zone, the valve core overcomes the propping force of the elastic component to open the differential pressure valve under the differential pressure action of the two ends of the piston, so that the executing cavity and the differential pressure detection cavity are communicated with each other. The hydraulic cylinder device has good stability and high pressure resistance capability and pressure pulse resistance capability.

Description

technical field

[0001] The invention relates to a hydraulic oil cylinder with a structure capable of detecting the position of the piston movement of the oil cylinder and controlling the movement (reversing, buffering, etc.) of the oil cylinder by converting the hydraulic pressure difference signal into an electric signal. Background technique

[0002] Generally speaking, a traditional hydraulic cylinder device includes a cylinder, a piston that reciprocates linearly in the cylinder, and a piston rod that is connected to the piston at one end and extends out of the cylinder at the other end. The two ends of the working cavity inside the cylinder are the quasi-control area of ​​the piston movement. When the piston moves to the quasi-control area of ​​the piston movement, the movement of the piston (including reversing and buffering) needs to be controlled.

[0003] At present, in mechanical equipment such as hydraulic cylinder reciprocating pumping (such as: concrete pumping ...
