Embodiment Construction

[0010] The hydraulic system described in the embodiment of the present invention adopts the connection method of the hydraulically controlled one-way locking circuit, and its main steps include:

[0011] (1) Firstly, a hydraulic lock is connected in series on the oil circuit on both sides of the hydraulic cylinder. The adjusting piston can be locked at any position of the stroke for a long time, and will not move due to external reasons. The locking accuracy depends on the leakage of the hydraulic cylinder and the oil. compressibility adjustment;

[0012] ⑵It is located outside the variable pump and connected to a reversing valve. By cutting off the oil inlet and outlet channels of the actuator to prevent movement due to external factors after stopping the movement, the O-shaped structure of the three-position reversing valve is used to close the hydraulic cylinder. two chambers;

[0013] (3) The reversing valve set adopts H-type structure.

Abstract

The invention discloses a connection method of a hydraulic system by adopting a hydraulic control one-way locking loop. The connection method is that hydraulic locks are connected in series with oil channels on two sides of a hydraulic cylinder; pistons are adjusted to realize the capacity of being locked for a long time in any positions in the route and can not move due to external reasons; the locking precision is adjusted according to the leaking and the oil compressing performance of the hydraulic cylinder; a reversing valve is connected with the outer part of a variable pump and can be used for switching off an oil inlet channel and an oil outlet channel of an executive element so as to prevent moving due to the external reasons after stopping moving; an O-shaped structure of a three-way reversing valve is adopted and is used for sealing two chambers of the hydraulic cylinder; and the arranged reversing valve is provided with an H shaped structure. The connection method has the beneficial effects that the oil channels are simplified, the reliability of action is ensured, the position reversing precision is relatively high, and the sufficient switching precision can be gained.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a connection method for a hydraulic system using a hydraulically controlled one-way locking circuit. Background technique [0002] Hydraulic technology is one of the key technologies to realize modern transmission and control. Due to light weight and small size, various components of hydraulic transmission can be conveniently and flexibly arranged according to needs. Combining with the latest technology, it has a high degree of automation and is easy to operate and control. It is easy to realize linear motion and a wide range of stepless speed regulation. To achieve overload protection, mineral oil is used as the working medium, which can be self-lubricated relative to the moving surface and has a long service life. With the continuous improvement of the degree of automation of hydraulic machinery, the number of hydraulic components used has increased sharply, and the miniatu...
