Description
Technical field
The utility model relates to oil cylinder, a kind of straight trailer oil cylinder of more specifically saying so.
Background technique
The oil cylinder design proposal generally is according to known conditions in the hydraulic system at present, designs with reference to oil cylinder design interrelated data and design proposal in the past.But in real work, it is very harsh to tend to occur the condition that the user gives, if this moment is by standard or by in the past conceptual design, the interference of axial dimension or radial dimension will take place, will well link up, coordinate this moment with the user, dare to break the normal procedure with the thinking of innovation, under the prerequisite that guarantees the oil cylinder performance, design cylinder structure compact as far as possible, satisfy user's requirement.
For example in the railway maintenance operation, when rail uses for a long time or be subjected to the external force modification, the rail of modification will be repaiied directly, to guarantee train running safety.At this moment the servicing machine that needs is exactly straight trailer.Straight trailer generally is field work, therefore requires to make compact structure, in light weight and easy-to-operat under the prerequisite of guaranteeing straight rail active force as far as possible.Straight trailer oil cylinder is the main power unit of straight trailer, limited by straight trailer general structure, and it must be compact structure, in light weight that straight trailer oil cylinder requires.
Summary of the invention
The purpose of this utility model is: a kind of straight trailer oil cylinder is provided, shortens the axial and radial dimension of oil cylinder, make the cylinder structure compactness, volume is little, and is in light weight, easy to operate, and performance is excellent.
Technical solution of the present utility model is: this straight trailer oil cylinder comprises piston, piston rod, cylinder barrel, guide sleeve, bonnet, filler opening and oil outlet, piston is in bonnet is installed in cylinder barrel, connection piston rod on the piston, piston rod is positioned on the cylinder barrel by guide sleeve, establish filler opening on the bonnet, set out hydraulic fluid port on the cylinder barrel, it is characterized in that: scyewed joint piston rod on the piston, a lock screw is installed between piston and piston rod is prevented circumferential movement.
In a kind of straight trailer oil cylinder of the present utility model, the right angle type filler opening is welded on the bonnet.
In a kind of straight trailer oil cylinder of the present utility model, the about 0.5mm of the inside turning of bonnet interior edge face, the bonnet end face is welded on the cylinder barrel and is locked by locking nut.
In a kind of straight trailer oil cylinder of the present utility model, in the end near cylinder barrel, guide sleeve adopts axle to seal with seal ring with cylinder barrel.
In a kind of straight trailer oil cylinder of the present utility model, between guide sleeve and the cylinder barrel guide ring is installed.
In a kind of straight trailer oil cylinder of the present utility model, piston and cylinder barrel adopt the hole to seal with seal ring.
In a kind of straight trailer oil cylinder of the present utility model, seal with O ring is adopted in piston and piston rod joint.
In a kind of straight trailer oil cylinder of the present utility model, on the boss of guide sleeve, mill several uniform mounting or dismounting grooves.
During use, hand pump pressure oil enters the oil cylinder filler opening by control valve, promotes piston-advance, piston rod drive jaw advances and makes the degree that rail is deformed to be needed, again by manually operated valve pilot pressure oil direction, and then the control piston bar advances or moves back, and finishes the rail maintenance operation.
The utlity model has following advantage: 1, the monolateral thickness of the thickness of cylinder barrel and guide sleeve try one's best little, the radial dimension compactness; 2, shorten the length of guide sleeve and piston, the axial dimension compactness; 3, piston and piston rod scyewed joint further shorten axial dimension; 4, filler opening adopts the right angle type welding, and rosin joint oil leakage phenomenon ratio is easier to hold; 5, the about 0.5mm of the inside turning of bonnet interior edge face, bonnet and cylinder barrel adopt end face welding rather than usual radially welding, save axial dimension; 6, between guide sleeve and the cylinder barrel guide ring is installed, is adopted axle to seal with seal ring at the end guide sleeve near cylinder barrel with cylinder barrel, hydraulic oil does not have much pressure to this after the helical thread portion throttling like this, and the reliability of sealing has increased; 7, mill several uniform mounting or dismounting grooves on the boss of guide sleeve, mounting or dismounting are convenient.
