TIF'wi='37'he='48' /) 1.5 damping holes with the switch -on of oil feed chamber, hydraulic pressure lock lock body below is equipped with the valve rod, be equipped with valve rod control switch groove on the valve rod, the utility model discloses set up two plungers and replace traditional plungers, through inside control circuit under the control of valve rod, can be alone or open the both sides lock core simultaneously, the rear overhang on -hook of satisfying the tractor constructs quietly subsides the requirement, has also satisfied agricultural implement floating state's requirement in the course of the work simultaneously.
Description
Technical field
The utility model relates to hydraulic machinery field, particularly relates to a kind of hydraulic control and locks device that is unidirectional or bidirectional open.
Background technique
The oil cylinder that bidirectional hydraulic lock is widely used in the machineries such as engineering transportation lifting needs in the oil circuit of pressurize, as (the mobile crane such as supporting leg loop and tractor of automobile, high-altitude operation vehicle), when its working principle is an oil pocket forward oil-feed, another chamber is oppositely fuel-displaced, otherwise easily right, when two chamber forward not oil-feeds, oppositely also obstructed, do not disturb by external load, play the effect of lock.Time traditional bidirectional hydraulic is locked in side oil-feed, the pressure of this side raises, lock core promotes plunger and moves toward opposite side, the lock core of opposite side is backed down, the oily oil return of opposite side, but tractor requires floating bit in the course of the work, requires that filler opening and two working holes all will lead to oil return, at this moment, a plunger all can not be opened both sides lock core simultaneously.
Summary of the invention
The utility model be intended to solve the deficiencies in the prior art, and provide a kind of both can the unidirectional control gear simultaneously can opening both sides lock core.
The utility model for achieving the above object, by the following technical solutions: a kind of hydraulic control locks device that is unidirectional or bidirectional open, it is characterized in that, comprise hydraulic lock lock body, control system oil circuit, described control system oil circuit comprises oil suction chamber, described hydraulic lock lock body comprises lock core, described lock core is two, be respectively the first lock core and the second lock core, described in described first lock core, the second lock core is symmetrical, two symmetrical plungers are provided with between described first lock core and described second lock core, be respectively the first plunger and the second plunger, be provided with between described first plunger and described second plunger
hole, described in
be provided with bottom hole and connect hole, be provided with below described connection hole
damping hole, described in
described in hole is passed through
damping hole and described oil suction chamber are connected, and are provided with valve rod below described hydraulic lock lock body, and described valve rod is provided with valve rod control switch groove.
The beneficial effects of the utility model are: the utility model arranges two plungers and replaces a traditional plunger in valve body, by internal control oil circuit under the control of valve rod, both sides lock core can be opened individually or simultaneously, filler opening and working hole can lead to oil return, meet the quiet settlement request of the rear hitch of tractor, also meet the requirement of agricultural machinery and implement quick condition in the course of the work simultaneously.
