Detailed description of the invention
Fig. 1 is a kind of hydraulic principle of specific embodiment of braking release hydraulic system provided by the utility model
Figure.
Specific embodiment
The core of the utility model is to provide a kind of braking release hydraulic system of hydraulic moving vehicle, is throttled by setting
Device is capable of providing buffering, controls braking time, while preventing hydraulic shock, protects control valve, improves device security and can
By property.Another core of the utility model is to provide a kind of hydraulic moving vehicle including above-mentioned braking release hydraulic system.
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation
The utility model is described in further detail for mode.
Referring to FIG. 1, Fig. 1 is a kind of specific embodiment of braking release hydraulic system provided by the utility model
Hydraulic schematic diagram.
Specific embodiment of the present invention provides a kind of braking release hydraulic system of hydraulic moving vehicle, including control
Valve, hydraulic pump, brake and throttling set.Wherein, control valve and hydraulic pump are arranged in parallel, i.e. the first interface and liquid of control valve
The oil inlet of press pump while the oil inlet and outlet A of connected system, the second interface of control valve are connected to simultaneously with the oil outlet of hydraulic pump
Brake, control valve is capable of the on off operating mode of control brake and oil inlet and outlet, while the second interface of control valve passes through throttling
Device 5 is connected to brake.
Under normal condition, control valve is in the open state, is connected to oil inlet and outlet A and brake, when needing to brake, cancel into
Pressure at oil outlet A, hydraulic oil successively can flow to oil inlet and outlet A, release system via throttling set and control valve by brake
Hydraulic oil in dynamic device, realizes braking；When cancelling braking, oil inlet and outlet A provides pressure, and hydraulic oil is successively passed through by oil inlet and outlet A
Brake is flowed to by control valve and throttling set, to open brake.When needing to open brake manually, control valve, which is in, is closed
State, oil inlet and outlet A can not be flowed to via control valve by brake by completely cutting off oil inlet and outlet A and brake, hydraulic oil, still, this
When hydraulic oil can be filled with to brake by hydraulic pump, oil inlet and outlet A passes through hydraulic pump and is connected to brake, realizes and opens braking
Device.
By the way that throttling set 5 is arranged, when brake discharges hydraulic oil, hydraulic oil can pass through the throttle of throttling set 5
After pass through control valve, flow out, braking time can be controlled eventually by oil inlet and outlet, that is, brake when have buffering, this
Valve advantage of lower cost can solve the problems, such as that legacy system upgrading optimization increases braking pooling feature at lower cost, brake oil liquid
It throttles when release through overdamp, can reduce Oil shocking, reduce oil leak and extend the service life of valve, protect control valve, mention
High device security and reliability.
Specifically, control valve can be 2/2-way reversal valve, when 2/2-way reversal valve is in the first working position, connection
Brake and oil inlet and outlet when 2/2-way reversal valve is in the second working position, completely cut off brake and oil inlet and outlet.I.e. normal shape
2/2-way reversal valve is in the first working position under state, and when needing to open brake manually, 2/2-way reversal valve is in second
Working position can also be used other kinds of reversal valve, or be had using other and change the valve for blocking connected state function.Wherein
2/2-way reversal valve can be the hand hydraulically controlled reversal valve 1 of 2/2-way, using manual and hydraulic control there are many control mode
Double control quickly adjusts on off operating mode as needed, easy to operate, convenient for control, other control modes can also be used, such as adopt
With solenoid directional control valve etc., it both is within the protection scope of the present invention.
In the braking release hydraulic system that specific embodiment of the present invention provides, hydraulic pump can be manual pump 6,
Certainly other kinds of hydraulic pump can also be used.
Hydraulic oil flows back in order to prevent, and at the oil inlet of manual pump 6 and oil outlet is provided with the first check valve, the
One check valve can allow for hydraulic oil to enter brake via manual pump 6 by oil inlet and outlet A, i.e. the first check valve can prevent
Hydraulic oil enters oil inlet and outlet A via manual pump 6 by brake.The quantity of the first check valve can be adjusted according to the actual situation,
It can be respectively provided with the first check valve at 6 both ends of manual pump, first check valve can also be only set at one end.
Meanwhile also settable second one-way valve 2, i.e. second one-way valve 2 one end and throttling set 5 in parallel with throttling set 5
One end connects the interface of control valve simultaneously, and connecting brake connects simultaneously for 2 other end of second one-way valve and 5 other end of throttling set
Mouthful.Second one-way valve 2 can allow for hydraulic oil to enter brake via control valve by oil inlet and outlet A, i.e., control valve, which is in, opens
When state, hydraulic oil in brake successively can only flow to oil inlet and outlet A via throttling set 5 and control valve, and cannot be via
Second one-way valve 2 flows to oil inlet and outlet A, but in turn when, hydraulic oil is successively single via control valve and second by oil inlet and outlet A
Enter brake to valve 2, since 5 resistance of throttling set is larger, brake cannot be entered via throttling set 5.Realize brake
Quick when opening, slowly braking has buffering when braking.
The quantity of brake can be according to circumstances adjusted, the brake of multiple parallel connections is set, specifically, brake includes simultaneously
Join the first brake 3 and second brake 4 of setting.
On the basis of the braking that above-mentioned each specific embodiment provides discharges hydraulic system, throttling set 5 is detachable
Definite value throttle valve or cellular type damping.The model of different cellular type damping or definite value throttle valve can be set according to different demands,
Meet different brake requirements, by adjusting the size of damping value, the switching realizing Quick brake or steadily braking, central hole type
Damping can damp for thin wall small hole or elongated hole, be convenient for changing, long service life.Further, it is adjustable that ratio can also be used
Throttle valve does not need to change the size that damping value can be adjusted, improves applicability.
In addition to above-mentioned braking discharges hydraulic system, it includes above-mentioned system that specific embodiment of the present utility model, which also provides a kind of,
The hydraulic moving vehicle of dynamic release hydraulic system, refer to the prior art for the structure of other each sections of the hydraulic moving vehicle, this
Text repeats no more.
Detailed Jie has been carried out to hydraulic moving vehicle provided by the utility model and its braking release hydraulic system above
It continues.Specific case used herein is expounded the principles of the present invention and embodiment, and above embodiments are said
The bright method and its core concept for being merely used to help understand the utility model.It should be pointed out that for the common of the art
For technical staff, without departing from the principle of this utility model, can also to the utility model carry out it is several improvement and
