Abstract
The invention discloses a hydraulic cylinder for driving a diagonal-drawing gantry crane or a diagonal-drawing trolley type hoist trolley. The hydraulic cylinder comprises a hydraulic cylinder body consisting of a cylinder barrel and a piston rod, wherein the tail of the cylinder barrel is provided with a distortion-resistant bracket; the cylinder barrel is provided with binaural trunnions and binaural hinged supports; the binaural trunnions are connected through self-lubricating shaft sleeves embedded in the binaural hinged supports; and the hanging head of the piston rod is connected with monaural hinged supports through self-lubricating oscillating bearings. The hydraulic cylinder has the advantages of solving the problem that the piston rod is deflected and bent in the working process of the hydraulic cylinder. In the extending and retracting process of the piston rod, the self-lubricating oscillating bearings realize automatic center adjustment of the hanging head at the end of the piston rod of an oil cylinder so as to bear radial and axial loads, and are combined and linked with sliding bearings in the binaural hinged supports, so that the self adaptation for deflecting, bending and twisting the hydraulic cylinder is realized. Under the full extension working condition of the piston rod, down warping of the tail of the hydraulic cylinder caused by the dead weights of a hydraulic cylinder barrel and hydraulic oil is reduced or eliminated under the action of the distortion-resistant bracket.
Description
Technical field
The present invention relates to the machine of tiltedly pulling and tiltedly draw platform hoist, especially relate to the hydraulic cylinder that is used to drive oblique sliding door machine or tiltedly draws the platform hoist dolly.
Background technology
Hydraulic and Hydro-Power Engineering partial building gate slot is arranged and is had gradient, when adopting door machine or platform hoist to open and close gate, the lifting mechanism wire rope becomes fixed angle with the vertical ground direction, and remain unchanged and to guarantee that gate normally opens and closes along the inclination gate slot, and the dolly of the horizontal component that is produced in opening process traction door machine or platform hoist causes gate normally to open and close along the track cross level displacement.Adopt oblique sliding door machine or tiltedly draw platform hoist, by the Driven by Hydraulic Cylinder dolly along the track cross level displacement, and utilize the dynamic balance of holding of hydraulic cylinder to open the horizontal component that is produced in the process, keep dolly and be in and tiltedly draw the position, to guarantee that gate is along the normal a kind of solution well of can yet be regarded as that opens and closes of gate slot.But since dolly along track cross level displacement generally more than five meters, this just requires the oil cylinder piston bar stroke also must be greater than five meters.And girder span centre camber causes hydraulic cylinder piston rod produces in running amount of deflection, door frame or bogie frame upper mounting plate and trolley track alignment error to cause hydraulic cylinder suffered bending in running, twisting action (as: same potential difference under the end carriage of the same side of trolley track difference of height, wheel, track local buckling, rail joint deviation etc. on gauge deviation, rail span relative mistake, the same cross section) when piston rod is stretched amount of deflection, door frame or bogie frame that the deadweight of cylinder barrel under the state produced entirely and installed, and will directly influence the normal operation of dolly.How to address the above problem, be the problem that those skilled in the art study always, but yet there are no the report of all relevant this respects.
Summary of the invention
The object of the invention is to provide a kind of and anti-ly scratches, anti-bending be used to the hydraulic cylinder that drives oblique sliding door machine or tiltedly draw the platform hoist dolly.
For achieving the above object, the present invention can take following technical proposals:
The hydraulic cylinder that is used to drive oblique sliding door machine or tiltedly draws the platform hoist dolly of the present invention, it comprises the cylinder body that is made of cylinder barrel, piston rod, be provided with the anti-crawl agentdefiection carriage at described cylinder barrel afterbody, cylinder barrel is provided with ears and props up hinge and ears free bearing, and described ears prop up hinge and link by the embedded self lubrication bearing of ears free bearing; The head that hangs of described piston rod is connected with the monaural free bearing by self-lubricating knuckle bearing.
Described anti-crawl agentdefiection carriage is by base, at interval symmetrical described base center line two support bodys disposed thereon and the shock absorber part that is separately positioned on described two support body tops constitute; The top of two support bodys is the inwardly inclined-plane of below inclination of symmetrical base center line, and described shock absorber part is arranged on the described inclined-plane.
Described shock absorber part is damping rubber block or damping spring plate.
Described piston rod is the hollow stem structure.
The invention has the advantages that and solve amount of deflection, the bending phenomenon that piston rod occurs in the hydraulic cylinder works process.During hydraulic cylinder works, it is hinged by self-lubricating knuckle bearing, monaural free bearing and dolly that head is hung in the piston rod end, cylinder barrel props up hinge by ears and the ears free bearing is fixed on the machine upper mounting plate or on the bogie frame, and the cylinder barrel afterbody places on anti-crawl agentdefiection carriage damping rubber block or the damping spring plate; Like this in the piston rod telescopic process, self-lubricating knuckle bearing realized the oil cylinder piston boom end hang an automatic aligning, to bear radial and axial load, simultaneously with the ears free bearing in sliding bearing combination interlock, realized hydraulic cylinder to scratch, bend, the self adaptation of twisting strain.Stretch entirely under the operating mode at piston rod, the hydraulic cylinder afterbody is under the effect of anti-crawl agentdefiection carriage, pre compressed magnitude effect by damping rubber block or damping spring plate produces upper support power, to resist stretching the amount of deflection that the cylinder barrel deadweight produces under the state entirely at piston rod, make liquid cylinder entity keep " one " word balance, reduced or eliminated because hydraulic cylinder cylinder barrel and hydraulic oil deadweight cause the downwarp of hydraulic cylinder afterbody.Which kind of damping compression-resistant material the anti-crawl agentdefiection carriage adopts, and anti-crawl agentdefiection carriage quantity is set can determines according to the deadweight of hydraulic cylinder, stroke.
