Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
Combined Fig. 2 by Fig. 1, shown in 3, a kind of pressure thick stick self-locking hydraulic oil cylinder, including cylinder body 1, in described cylinder body 1, be provided with work
Stopper rod 2, the space in cylinder body 1 is divided into rod chamber 11 and rodless cavity 12, described rod chamber 11 and by described piston rod 2
One oil-in 13 is connected, and described rodless cavity 12 is connected with the second oil-in 14, described rod chamber 11 and rodless cavity 12
Between be provided with reversal valve 3, described reversal valve 3 is for being switched on or off rod chamber 11, the oil circuit of rodless cavity 12.Described nothing
Accumulator 5 it is provided with between bar chamber 12 and reversal valve 3.The arranging of accumulator can store the oil that rod chamber, rodless cavity are unnecessary, when being
During system trace permeability, now accumulator can promptly repairing, it is ensured that the security performance of product.Described reversal valve 3 is two two
Electric change valve.If meeting blackout condition prominent, can release pressure thick stick with manual reverse of direction, the beneficial effects of the utility model are,
Rod chamber and the oil-filled pressurization of rodless cavity to cylinder body respectively by the first oil-in and the second oil-in, now so that there is bar
Chamber is identical with the oil pressure of rodless cavity, and rod chamber and rodless cavity are cut off by reversal valve so that cylinder body realizes self-locking, and energy consumption is little, energy
Reliably visitor or article are securely fastened to assigned position by pressure thick stick；After reversal valve commutation, due to rod chamber with without bar
Chamber hydraulic oil can freely turn on, because the area of rodless cavity is more than rod chamber, and the energy of release accumulator, thus easily promote
Piston rod moves to rod chamber, thus unlocks pressure thick stick so that visitor can freely come in and go out or article easily take out.
It is provided with choke valve 4 between described rod chamber 11 and reversal valve 3.Specifically, described choke valve 4 is one-way throttle
Valve, this one-way throttle valve is for flowing into rodless cavity 12 or by the hydraulic pressure of rodless cavity 12 by the hydraulic oil of rod chamber 11 through restriction
Oil flows into rod chamber 11 through unidirectional mouth, restriction.Such structure make solenoid directional control valve must not electricity time, rod chamber and rodless cavity
Being not turned on, when solenoid directional control valve obtains electric, then the hydraulic oil of rod chamber enters rodless cavity through the restriction of one-way throttle valve, now may be used
To regulate the size of restriction as required, it is ensured that pressure thick stick is slowly opened, it is to avoid pressure thick stick is opened too fast and hurt visitor or work
Personnel；After new visitor sits down, pressing pressure thick stick, the hydraulic oil of rodless cavity is released through reversal valve, one-way throttle valve by piston rod
Unidirectional mouth to rod chamber, now reversal valve dead electricity, hydraulic oil by locked in rod chamber, it is achieved self-locking.
The first pressure measuring tie-in 15, the second described oil-in 14 it is provided with between described the first oil-in 13 and rod chamber 11
And it is provided with the second pressure measuring tie-in 16 between rodless cavity 12.It is provided with first unidirectional between described the first oil-in 13 and rod chamber 11
Valve 17, is provided with the second check valve 18 between described the second oil-in 14 and rodless cavity 12.Such structure can avoid bar
Reflux at chamber and rodless cavity, pressure measuring tie-in the oil pressure that can monitor at rod chamber and rodless cavity is set, thus when avoiding leakage of oil
Start recreation facility, improve the security performance of product.
Being provided with sealing guide pin bushing 6 in described cylinder body 1, described piston rod 2 is located at outside cylinder body 1 through sealing guide pin bushing 6.Described
Piston rod 2 be provided with ring-shaped step breach 21, be provided with close with what cylinder body 1 inwall fitted in described ring-shaped step breach 21
Sealing 7.Such structure makes product seal more preferably.
