Net-fault comprehensive operation vehicle derails, and is especially happened at the operating environments such as tunnel, mountain area or bridge than narrow place, allows
Operation Van returns the problem of track time and effort consuming.Due to being limited by work vehicle sizes and installation space, and combine Operation Van
Weight and heavy burden devise this small volume, simple and reasonable vertical support oil cylinder, but it has good stabilization
Property, enough support forces, impulse stroke is adjustable and run action is steady, and convenient operation and control is flexible.It can be by operation of derailing
Vehicle lifts vertically, and coordinates with translation device, need not expend a large amount of manpowers, the operation of oil cylinder is carried by Operation Van, just suitable
Profit, the Operation Van that will quickly derail are moved back to track again.Ensure not allow piston rod in operation using fagging and locking device simultaneously
It is slid from cylinder barrel in vehicle driving process.
The technical solution of the utility model：A kind of vertical support oil cylinder for contact net comprehensive operation vehicle includes cylinder
Cylinder, piston, piston rod, guide sleeve, cylinder bottom, fagging and locking device, one end of the piston rod connect juxtaposition with the piston
In in the cylinder barrel, the guide sleeve playing the guiding role, the piston rod and institute are set in the peripheral surface of the piston rod
It states and is slidably installed between guide sleeve, the fagging is located at that cylinder barrel is outer and connect with the other end of the piston rod, and the locking fills
It sets and is sleeved on the outer surface of cylinder barrel and fagging.
Preferably, the locking device includes two and semicircular is sleeved on the outer surface of the cylinder barrel and the fagging
Clamp ring, screw bolt and nut, turn in the lower part of the clamp ring to form annular and protrude out, the inner surface which protrudes out and the fagging
Outer surface be affixed, the both ends on the clamp ring top are respectively provided with lug, perforation are reserved at the lug, for across the bolt
After screw the nut and be fixedly connected.
Preferably, the fagging is fixed on by sunk screw on the fagging.
Preferably, one end of the piston rod is connected through a screw thread with the piston.
Preferably, the cylinder barrel is threadedly coupled with the guide sleeve.
Preferably, the cylinder barrel is welded with the cylinder bottom.
Preferably, the cylinder bottom is provided with 2 location holes and 4 mounting holes.
Preferably, a diameter of 140mm of the piston, a diameter of 90mm of the piston rod, the pistons work stroke
For 300mm, the length of oil cylinder is 500mm.
The utility model has the beneficial effect that：It is the vertical support oil cylinder small volume of the utility model, simple in structure
Rationally, meet the narrow requirement of locomotive chassis installation space, but it is with good stability, enough support forces can be very
Successfully derailing Operation Van is lifted vertically, and derailing Operation Van is moved back to track with translation device cooperation, without expending
A large amount of manpower.Since piston rod is downward when the oil cylinder of the utility model is vertically-mounted, Operation Van is running at high speed in order to prevent
When, because pipeline rupture or sealing ring damage, piston rod slide from oil cylinder, the normally travel of Operation Van is influenced, in work
Fagging is secured on stopper rod, and locking device is used in combination to be sleeved on oil cylinder and fagging.When needing using oil cylinder, locking device is removed
.When carrying out vertical lifting, fagging can play the role of supporting piston rod.
