Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is a kind of hydraulic principle signal of safe and reliable compression type garbage truck hydraulic protector of the utility model
Figure；
Fig. 2 is the schematic illustration of hydraulic lock；
Fig. 3 is the appearance schematic diagram of hydraulic lock.
Specific embodiment
As shown in one of attached drawing 1-3, the utility model includes more than one operation oil cylinder, point connecting with operation oil cylinder
Branch oil circuit, the working connection with each branch's oil circuit connection, the working connection are equipped with the first hydraulic control one-way valve 7, the first one-way throttle
Valve 8 is equipped with hydraulic lock on each branch's oil circuit, and the hydraulic lock is directly connect with operation oil cylinder.
In a preferred embodiment, the device mainly includes oil-suction oil filter 1, gear pump 3, overflow valve 4, solenoid directional control valves
6, the first hydraulic control one-way valve 7, the first hydraulic lock 9, the second hydraulic lock 10, the first lift cylinder 11 second lift cylinder 12 and returns
Oil strainer 13, wherein by the first hydraulic control one-way valve 7, the first one-way throttle valve 8, the first hydraulic lock 9, the combination of the second hydraulic lock 10
At the core of protective device, the small chamber of the first hydraulic control one-way valve 7 and the first lift cylinder 11, the second lift cylinder 12 connects
It connects, when the first lift cylinder 11, when the second lift cylinder 12 crosses position of centre of gravity, shields to the small chamber of oil cylinder, first is single
To throttle valve 8 in main oil return line one back pressure value of raw offer, system oscillation is prevented.First hydraulic lock 9, the second hydraulic lock 10 is to first
Lift cylinder 11, the big chamber of the second lift cylinder 12 play safeguard protection, are separately positioned on the first lift cylinder 11, and second mentions
In 12 branch oil circuit of oil-lifting jar, and it is directly installed on the first lift cylinder 11 respectively, on the seat board of the second lift cylinder 12, in
Between not extra pipeline connected with connector.
Fig. 2 schematically expresses the first hydraulic lock 9, the hydraulic principle and its shape assumption diagram of the second hydraulic lock 10.With
For first hydraulic lock 9, it comprises the second hydraulic control one-way valve 14, the second one-way throttle valve 15 and third one-way throttle valve 16,
Wherein the second hydraulic control one-way valve 14 plays a part of safe locking, and the second one-way throttle valve 15 plays synchronous adjustment, third list
Oscillation adjustment effect is played to throttle valve 16.The appropriate third one-way throttle valve 16 that adjusts forms suitable back pressure value, it is ensured that first
Lift cylinder 11,12 smooth motion of the second lift cylinder, effectively eliminates mechanism vibrations and impact.Meanwhile to guarantee that first is promoted
Oil cylinder 11, the synchronism of the second lift cylinder 12 movement, is provided with third one-way throttle valve 16, when the first lift cylinder 11 rises
When speed is higher than the second lift cylinder 12, third one-way throttle valve 16 is adjusted clockwise, improves its return oil pressure value, reduces second
12 rate of climb of lift cylinder；On the contrary when 11 rate of climb of the first lift cylinder is higher than the second lift cylinder 12, adjust counterclockwise
Third one-way throttle valve 16 is saved, its return oil pressure value is reduced, increases 12 rate of climb of the second lift cylinder, is achieved in first and mentions
Oil-lifting jar 11, the synchronization action of the second lift cylinder 12.It is represented from 9 shape assumption diagram of the first hydraulic lock to be promoted with first
6 installation hole locations that oil cylinder 11 connects pass through being directly connected to for this hole location realization the first hydraulic lock 9 and the first lift cylinder 11.
The circuit safety guard that promoted of the utility model includes the small chamber protective device and branch's oil circuit on working connection
On big chamber protective device, while big chamber protective device carries oscillation regulatory function and synchronous adjustment function, the above size chamber again
The device protected respectively constitutes a kind of more safe and reliable protection system.
Small chamber protective device on the working connection refers to, fluid-control one-way is arranged on the working connection in hoisting mechanism circuit
Valve, this hydraulic control one-way valve are connected with the small chamber of lift cylinder, guarantee that the safety behind focus point position is crossed in hoisting mechanism rising
Performance.After crossing focus point due to each hoisting mechanism of compression vehicle, descent direction is the direction far from operator, therefore to mentioning
The requirement of the small chamber protection of oil-lifting jar is lower than the requirement protected to the big chamber of lift cylinder, and one-way hydraulic lock is arranged on working connection
Meet its protection to require.
Safety guard on branch's oil circuit is the key component of the utility model, for avoid pipelines from bursting and
The safety failure hidden danger of connector oil leak, takes on the lift cylinder of the right and left respectively that directly setting one-way hydraulic lock is a kind of
Effective solution.The big chamber of lift cylinder is the driving chamber of enhancing action, and load force is kept vertical for a long time in lifting process
Downwards, therefore more important to the safeguard measure of big chamber, this mode avoids pipeline and connector connection between control valve and oil cylinder,
Security performance is obviously improved.
The oscillation adjusts and is adjusted in synchronism function, wherein oscillation regulatory function refers on one-way hydraulic lock oil return line
One-way throttle valve is set, in order to form certain back pressure on oil return line, the variation of the intracavitary oil pressure of oil cylinder is avoided to lead to list
It is frequently opened and closed to hydraulic lock and forms system oscillation, cause mechanism high vibration and impact.Being adjusted in synchronism function is to guarantee to mention
The synchronism for rising mechanism kinematic, guarantees that it grows steadily.Since the utility model is respectively set on the lift cylinder on both sides
Hydraulic lock, thus the unlatching of hydraulic lock will by mechanism fabrication error, oil cylinder cracking pressure difference, pipeline arrangement difference etc. because
The influence of element, the synchronism on both sides is relatively difficult to guarantee, therefore the utility model is respectively set separately in big chamber one-way hydraulic lock oil circuit
One one-way throttle valve, plays synchronous adjustment.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention, within the spirit and principle of the utility model,
Any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.
