The invention provides an improved structure of a positioning ring for a front top hydraulic oil cylinder of a dumper. The structure comprises an oil cylinder cover assembly, an outer cylinder assembly and an oil cylinder positioning ring, wherein the lifting end of the outer cylinder assembly is fixed in the oil cylinder cover assembly; the oil cylinder positioning ring is fixed on the periphery of the outer cylinder assembly; at least four blind holes are circumferentially and uniformly distributed in the outer ring surface of the oil cylinder positioning ring; a buffer nail is arranged in each blind hole; the outer end of the nail rod of each buffer nail extends out of the corresponding blind hole, and is in clearance fit with the inner circumference of the oil cylinder cover assembly; and each buffer nail comprises a nail head, a nail rod extends upward from the center of the upper end face of the nail head, and the diameter of each nail head is slightly more than the diameter of the corresponding nail rod. The improved structure can be used for inhibiting abnormal sound generated by collision between the oil cylinder positioning ring and the metal oil cylinder cover assembly, and has the advantages of simple process, low cost and convenience in popularization and application.
Description
Technical field
The invention belongs to hydraulic oil cylinder of self-discharging vehicle field, more particularly to dumper front top hydraulic jack are improved with locating ring
Structure.
Background technology
Hydraulic oil cylinder of self-discharging vehicle be by hydraulic pressure oil medium by hydraulic energy transfer for mechanical energy hydraulic actuator；Effect
When, oil pump is pressurizeed to hydraulic oil, and high pressure liquid force feed is entered in oil cylinder realizes lifting, and hydraulic jack is by support with compartment even
Connect, reach the effect for compartment being lifted upwards and being unloaded.
As shown in figure 1, the structure of dumper front top hydraulic jack is：Including oil cylinder outer housing assembly, outer shell assembly and oil
Cylinder locating ring, the lifting end of outer shell assembly is fixed in oil cylinder outer housing assembly, and cylinder locating ring is fixed on the outer peripheral face of outer shell assembly
On, oil cylinder locating ring is coordinated with the inner peripheral surface gap of oil cylinder outer housing assembly；The outer shell assembly is one pole hydraulic jack or multistage
Hydraulic jack, its structure is known technology；The oil cylinder locating ring is play the guiding role in oil cylinder lifting.
Existing front top hydraulic jack locating ring is welded together with outer shell assembly using monoblock type steel structure, by
Gap coordinates and is always shaped as the gap of 3-5mm with oil cylinder outer housing, when the resonance during automobile starts or travel in idling, shake and
Gap causes oil cylinder outer housing assembly to vibrate, and oil cylinder locating ring collides the defect for producing abnormal sound with the internal face of oil cylinder outer housing assembly.
Accordingly, it would be desirable to improve to existing front top hydraulic jack locating ring.
Content of the invention
For overcome resonance of the existing automobile during idling starts or travels, shake and gap cause oil cylinder locating ring with
The internal face collision of oil cylinder outer housing assembly produces the defect of abnormal sound, and it is fixed that a kind of dumper front top hydraulic jack of present invention proposition is used
Position ring improved structure.
For this purpose, the technical scheme is that：Dumper front top hydraulic jack locating ring improved structure, including oil cylinder
Outer housing assembly, outer shell assembly and oil cylinder locating ring, the lifting end of outer shell assembly is fixed in oil cylinder outer housing assembly, oil cylinder locating ring
It is fixed on the outer peripheral face of outer shell assembly；It is characterized in that：At least four are evenly distributed on the outer ring surface of oil cylinder locating ring blind
Hole, is provided with buffering nail in each blind hole, the nail rod outer end for buffering nail extends the inner circumferential of rear and oil cylinder outer housing assembly from blind hole
Face gap coordinates；Buffering the structure that follows closely is：Including ailhead, the upper surface center of ailhead has upwardly extended nail rod, ailhead straight
Footpath is slightly larger in dimension than the diameter dimension of nail rod.
To the further restriction of technique scheme, blind threaded connection on the buffering nail and oil cylinder locating ring, its
Attachment structure is：The hole wall of blind hole is provided with female thread, the ailhead side face of buffering nail and is provided with the external screw thread for being engaged with female thread,
The nail rod outer face of buffering nail is provided with flat recess.Advantage：Screw connection structure has simple structure, connection reliability, assembly and disassembly side
Just the advantages of；Flat recess can carry out Fast Installation using screwdriver to buffering nail, so as to improve work efficiency.
To the further restriction of technique scheme, the buffering nail is made using high-strength nylon.Advantage：High intensity Buddhist nun
The noise that dragon collides generation with oil cylinder outer housing assembly is little, plays the purpose of further noise reduction, and does not allow fragile.
Beneficial effect：1. at least four bufferings nail is evenly distributed in, is avoided that oil cylinder locating ring is sent out with oil cylinder outer housing assembly
Raw collision：2. the diameter dimension of ailhead is larger, improves bonding strength；The diameter dimension of nail rod is less, can reduce slow during collision
Punch and the contact area of oil cylinder outer housing assembly, put contact form and significantly reduce noise；3. existing oil cylinder can be positioned
Ring is improved, it is to avoid the problem of the wasting of resources；4. the present invention can suppress oil cylinder locating ring with metal oil cylinder outer housing assembly
The abnormal sound that collision is produced, the structure has the advantages that process is simple, low cost, easy to utilize.

Specific embodiment
As shown in Figures 2 and 3, dumper front top hydraulic jack locating ring improved structure, including oil cylinder outer housing assembly
1st, outer shell assembly 2 and oil cylinder locating ring 3, the lifting end of outer shell assembly 2 is fixed in oil cylinder outer housing assembly 1, and oil cylinder locating ring 3 is solid
It is scheduled on the outer peripheral face of outer shell assembly 2；At least four blind holes are evenly distributed on the outer ring surface of oil cylinder locating ring 3, each blind hole
Buffering nail 4 is inside equipped with, and four buffering nails are combined with guide effect；As shown in Figure 4 and Figure 5, the structure of buffering nail 4
For：Including ailhead 401, the upper surface center of ailhead 401 upwardly extends the nail rod 402 of coaxial line, the diameter chi of ailhead 401
The very little diameter dimension slightly larger than nail rod 402；Buffering follows closely 4 and the blind threaded connection on oil cylinder locating ring, and its attachment structure is：Blind
