Abstract
The utility model discloses a kind of fluid pressure drive devices with locking mechanism.It is combined and is connected and composed with locking mechanism by hydraulic mechanism, hydraulic mechanism includes oil cylinder shell, piston；The piston includes the piston mandril that piston pars contractilis and diameter are less than piston pars contractilis diameter；Locking mechanism includes lockplate, double threaded screw；The lockplate center has less than piston pars contractilis diameter, greater than the centre bore of piston mandril diameter, and plunger lock state is locked out plate centre bore and is inserted in piston mandril and is connected and fixed by double threaded screw and oil cylinder shell.The utility model, which is used, carries out picking-up locking to piston with the lockplate of piston pars contractilis diameter matches, in the case where the valve of hydraulic mechanism oil cylinder outer wall upper and lower cavity oil inlet and outlet is damaged or is not closed completely, the locking device by being installed on piston pars contractilis outer end locks firm piston.Device locked secure is reliable, realizes duplicate protection, is improved hydraulic headstock gear installation or maintenance safety coefficient and efficiency.
Description
Technical field
The utility model belongs to hydraulic machine design manufacture technology field, in particular to a kind of with the hydraulic of locking mechanism
Driving device.
Background technique
The working plate door or gates of segmental shape of large hydropower station arrangement, hoisting mechanism mainly uses hydraulic headstock gear, hydraulic
Headstock gear is influenced by self structure, and bulk is longer after in lift gate, piston rod all stretches out, and piston rod is full when factory
Portion is recovered to oil cylinder bottom, horizontal transport to erecting bed.By the valve of closing oil cylinder outer wall upper and lower cavity oil inlet and outlet when lifting
Piston rod is locked.Once during vertical lifting or turn upper and lower cavity exits and entrances valve be not closed completely or suddenly by
Damage, piston rod are possible to scurry out suddenly, cause severe compromise to the equipment and personnel of surrounding.
Summary of the invention
The utility model is insufficient according to prior art to disclose a kind of fluid pressure drive device with locking mechanism.This reality
To solve the problems, such as that being to provide a kind of pair of fluid pressure drive device effectively prevent piston rod in turn or vertical lifting process with novel
The safety locking protective device scurried out suddenly.
The technical solution of the utility model is as follows:
Fluid pressure drive device with locking mechanism, is combined with locking mechanism by hydraulic mechanism and is connected and composed, and feature exists
In:
The hydraulic mechanism includes oil cylinder shell, piston；The piston includes that piston pars contractilis and diameter are stretched less than piston
The piston mandril of contracting portion diameter；
The locking mechanism includes lockplate, double threaded screw；The lockplate center has less than piston pars contractilis diameter, greatly
In the centre bore of piston mandril diameter, plunger lock state be locked out plate centre bore be inserted in piston mandril and by double threaded screw with
Oil cylinder shell is connected and fixed.
The oil cylinder shell front end ring piston mouth has connecting flange, is symmetrically arranged with bolt hole on connecting flange；It is described double
Head screw rod one end is connected and fixed with bolt hole, and the other end is connected and fixed by nut and lockplate.
There is the connecting flange of four double threaded screw the connection lockplates and oil cylinder housing forward end.
The utility model lockplate centre bore circumferentially-spaced is disposed with the lifting lug for handling connection.
The utility model helpfulness: the utility model, which is used, carries out piston with the lockplate of piston pars contractilis diameter matches
Locking is held up, existing hydraulic mechanism is restructured, matches it with lockplate.It is passed in and out in hydraulic mechanism oil cylinder outer wall upper and lower cavity
In the case that the valve of hydraulic fluid port is damaged or is not closed completely, it is living that the locking device by being installed on piston pars contractilis outer end locks jail
Plug.The apparatus structure is simple, and locked secure is reliable, and operation is easy for installation, realizes pair for effectivelying prevent piston rod to scurry out suddenly
It protects again, reduces security risk, be improved hydraulic headstock gear installation or maintenance safety coefficient and efficiency.
Detailed description of the invention
Fig. 1 is fluid pressure drive device schematic cross-sectional view；
Fig. 2 is the utility model locking device schematic diagram.
In figure, 1 is locked out plate, and 2 be nut, and 3 be lifting lug, and 4 be double threaded screw, and 5 be piston pars contractilis, and 6 be bolt hole, and 7
It is connecting flange, 8 be piston mandril.
Specific embodiment
The present invention will be further described With reference to embodiment, and specific embodiment is to the utility model
The further explanation of principle, does not limit the utility model in any way, and technology same or like with the utility model does not have
Range beyond the utility model protection.
In conjunction with attached drawing.
Fluid pressure drive device with locking mechanism, is combined with locking mechanism by hydraulic mechanism and is connected and composed.
Hydraulic mechanism includes oil cylinder shell, piston；The piston includes that piston pars contractilis 5 and diameter are less than piston pars contractilis
The piston mandril 8 of 5 diameters；
Locking mechanism includes lockplate 1, double threaded screw 4；1 center of lockplate has less than 5 diameter of piston pars contractilis, is greater than and lives
Fill in 8 diameter of mandril centre bore, plunger lock state be locked out plate centre bore be inserted in piston mandril 8 and by double threaded screw 4 with
Oil cylinder shell is connected and fixed.
Oil cylinder shell front end ring piston mouth has connecting flange 7, and bolt hole 6 is symmetrically arranged on connecting flange 7；Double threaded screw
4 one end are connected and fixed with bolt hole 6, and the other end is connected and fixed by nut 2 with lockplate 1.
There are four double threaded screws 4 to connect the connecting flange 7 of lockplate 1 and oil cylinder housing forward end.
1 centre bore circumferentially-spaced of lockplate is disposed with the lifting lug 3 for handling connection.
Embodiment, as shown, the fluid pressure drive device with locking mechanism, combines company with locking mechanism by hydraulic mechanism
Connect composition, comprising: lockplate 1, double threaded screw 4, attaching nut 2, the locking shell lug 3 of locking mechanism；The piston of hydraulic mechanism
Bolt hole 6 on pars contractilis 5, hydraulic mechanism shell, connecting flange 7, piston mandril 8；Piston pars contractilis 5 is received in off working state
It shrinks in hydraulic mechanism cylinder shell body.
Lockplate 1 is process by thick steel plate, and piston pars contractilis 5 is connect by piston mandril 8 with gate, and connection is removed
Afterwards, piston pars contractilis 5 is all recovered to oil cylinder bottom, is hung on locking shell lug 3 with chain block, from 8 end of piston mandril
Locking mechanism is inserted in.
The reserved or prefabricated bolt hole 6 on connecting flange 7.This example is on the connecting flange 7 by hydraulic mechanism cylinder shell
The bolt that is fixedly connected symmetrically remove 4 to 6, bolt hole 6 is reserved, with the double threaded screw 4 being process from the company of lockplate 1
It connects hole to penetrate, is tightened and has been split out in reserved bolt hole 6 in connecting flange 7.
After connecting flange 7 and locking screw 4 are tightened, the other end passes through the fixed completion pair of lock nut 2 below lockplate 1
The limitation locking of piston.
