Description
Technical field
The present invention relates to light railway fluctuating Oil cylinder, specially a kind of super-pressure titanium alloy drawing oil cylinder.
Background technology
In Special zones such as " under power networks, on bridge, in tunnel ", when train occurs security incident, large-scale rescue aid without
Method enters, and how by locomotive traction to safety place, realizes rapid rescue；In the wild, occur having an impact train safety on railway
Barrier, how rapid removing obstacles thing, it is ensured that train traffic safety；Without pulling equipment large-sized workshop, how to facilitate reality
Existing equipment traction turnover factory building.
Existing large-scale pulling equipment carries out traction and turns to locomotive in Special zones such as " under power networks, on bridge, in tunnel "
Move, because its is bulky, heavier-weight, and hauling distance is shorter, there is a problem of cannot be introduced into or entering inconvenience, easily indulge in
Miss rescue time.
The content of the invention
The present invention cannot be introduced into or delay into inconvenience to rescue to solve existing pulling equipment because unreasonable structure is present
Help the problem of time, there is provided a kind of super-pressure titanium alloy drawing oil cylinder.
The present invention adopts the following technical scheme that realization：Super-pressure titanium alloy drawing oil cylinder, including inner cylinder tube and outer shell
Cylinder, is provided with piston rod between inner cylinder tube and outer cylinder, inner cylinder tube is provided with the cylinder bottom fixed with both, cylinder with outer cylinder left end
Bottom left side is fixed with slideway head body I, and the fairlead being connected with outer cylinder inner thread is provided between outer cylinder and piston rod, interior
Cylinder barrel right-hand member is provided with the pressure ring being connected with inner cylinder tube outer wall thread, and piston rod right-hand member is provided with and is connected with piston rod outer wall thread
Slideway head body II, be provided with and formed outside the external application guide ring and piston of dynamic sealing with both between piston rod left side and outer cylinder
Sealing, the interior use guide ring and piston interior sealing that dynamic sealing is formed with both are provided between piston rod left side and inner cylinder tube, are led
To O-shaped back-up ring that static seal is formed with both is provided between set and outer cylinder, it is provided between fairlead and inner cylinder tube and two
Person forms guide ring, piston rod packing and the dust ring of dynamic sealing, and external application guiding is provided between inner cylinder tube right-hand member and piston rod
Ring I, is provided with the grip slide I for sliding up and down in slideway head body I, the grip slide for sliding up and down is provided with slideway head body II
The upper end of II, grip slide I and grip slide II is respectively connected with pull bar, and the lower end of grip slide I and grip slide II is all connected with
There is handle ring, outer shell drum outer wall is provided with into time liquid joint, pulling seat and rubber protecting jacket.
During operation, drag rope one end is connected with locomotive, and the other end is passed through from inner cylinder tube center；Tense rope one end and draw
Seat connection, the other end is fixed on rail.When drawing oil cylinder cavity of resorption feed liquor, piston rod stretches out, and grip slide II withstands traction
Front-end-cone block end face on rope, stretches out in the lump under piston rod effect, while the rear end cone block on drag rope is clamping cunning
Slided on the inclined-plane of block I, and be stuck on the end face of grip slide I, thus drive locomotive to move an impulse stroke；Work as traction
During cylinder upper cavity oil feed liquor, piston rod withdraws, and grip slide I withstands end cone block end face after drag rope, and the inclined-plane of grip slide II exists
Slided on front-end-cone block on drag rope, and be stuck in front-end-cone block rear side, complete a working cycles.Similarly, drawing oil cylinder
By stretching out and withdrawal shuttling movement for piston rod, realize that drag rope drives the movement of locomotive relatively long distance.When need dismounting
During drag rope, draw ring pull-up is driven simultaneously grip slide I, grip slide II lift, and draw ring is rotated by 90 °, now,
Drag rope is reversely extracted out from inner cylinder tube, is overcome existing pulling equipment and be cannot be introduced into or enter because unreasonable structure is present
Inconvenience delays the problem of rescue time.
Reasonable in design reliability of the present invention, coordinates oil cylinder to stretch and realizes that locomotive is moved over long distances using band cone block drag rope
It is dynamic and small volume, lightweight, into convenient, rescue time is saved, with simple structure, easy to operate and low cost
Advantage.
