Abstract
The utility model relates to a plunger type oil derrick telescopic oil cylinder, belongs to the matching device field of oil drilling and maintenance equipment, comprising a flange, a plunger, a guide sleeve, a cylinder body, an air exhausting plug, an one-way valve and nuts. The cylinder body is sheathed on the plunger. The bottom of the plunger is provided with the flange, and the central part is provided with the one-way valve. The guide sleeve is installed between the plunger and the cylinder body. A through hole is arranged on the one-way valve along the axial direction, and four small holes are distributed uniformly on the one-way valve along the radial direction. The air exhausting plug is installed at the top of the cylinder body. The cylinder body moves when the telescopic oil cylinder is lifted. The internal wall of the cylinder body does not need mechanical processing, and the plunger can be processed section by section. The plunger type oil derrick telescopic oil cylinder solves the problems that the length-diameter ratio is large, the sealability is poor, the cylinder body is difficult to be processed and is easy to be bent existed in the general piston type hydraulic oil cylinder. The plunger type oil derrick telescopic oil cylinder has small length-diameter ratio, strong rigidity and good sealability, is safe and stable to be lifted, is provided with the one-way valve at the oil inlet of the plunger, will not appear the phenomena that the oil cylinder and oil derrick fall rapidly when an oil inlet pipeline breaks down even if the oil pipe is burst, and ensures the safety of operating personnel and the device.
Description
Technical field:
The utility model relates to a kind of plunger type derrick telescopic oil cylinder that oil such as well repairing machine, truck-mounted drill rig and wheel-type working machine bore the equipment of repairing that is used for, and belongs to oil and bores the coordinative composition of equipments device field of repairing.
Background technique:
Well repairing machine, truck-mounted drill rig, wheel-type working machine are the indispensable equipment of oil drilling well workover, and derrick is again the vitals of these several equipment.During operation, derrick be worked being raised to precalculated position ability operation; After fulfiling assignment, flat the crouching of again derrick being fallen at the equipment top, the equipment of assurance meets the requirement that national road vehicle travels.The mode of hoisting of derrick has two kinds at present: the one, and adopt the machinery type of wire rope and pulley to hoist, the 2nd, adopt the hydraulic jack mode to hoist.Because stable action when hydraulic jack hoists is safe and reliable, finds broad application.Normally used lift oil tank is the piston-type hydro compressing cylinder, but because the stroke that hoists is long, makes the slenderness ratio of piston reach tens times more than, causes the cylinder body processing difficulties, and stressed back is flexible, and poor sealing performance, influences the work effect of complete machine.
Summary of the invention:
The purpose of this utility model is: by movement of cylinder block, inboard wall of cylinder block need not machining when a kind of hoisting was provided; The processing of plunger sectional, the slenderness ratio of hydraulic jack is little, and rigidity is strong, good airproof performance, the plunger type derrick telescopic oil cylinder of the safety and steady that hoists.
The derrick telescopic oil cylinder.
The utility model is to realize above-mentioned purpose by following technical solution:
This plunger type derrick telescopic oil cylinder is made of flange, plunger, guide pin bushing, cylinder body, air relief cock, one-way valve, nut and inipple, it is characterized in that: be set with a cylinder body on the plunger, the bottom of plunger is shaped on flange, and spring and one-way valve are equipped with in bottom centre; Two ends between plunger and the cylinder body respectively are provided with a guide pin bushing; The bottom of cylinder body is fixed with packing ring, seal ring b and O shape circle by nut.
Described one-way valve axially is shaped on a through hole, and the footpath upwards is evenly equipped with 4 apertures.
Air relief cock is equipped with at described cylinder body top.
Adopt inipple to be formed by connecting after the described plunger segmentation processing, inipple two ends and plunger connector place are provided with seal ring a respectively.
The utility model compared with prior art has following beneficial effect:
This plunger type derrick telescopic oil cylinder adopts plunger-type structure, is slided at plunger surface by cylinder body, has solved that conventional piston-type hydro compressing cylinder slenderness ratio is big, the cylinder body processing difficulties, and is flexible, the problem of poor sealing.Filler opening place at plunger is provided with one-way valve, goes wrong at in-line, even the oil pipe explosion the phenomenon that oil cylinder and derrick fall rapidly can not occur yet, guarantees operator and device security.
Description of drawings:
Accompanying drawing is the structural representation of plunger type derrick telescopic oil cylinder.
Among the figure: 1, flange, 2, plunger, 3, guide pin bushing, 4, cylinder body, 5, air relief cock, 6, seal ring a, 7, one-way valve, 8, packing ring, 9, seal ring b, 10, O shape circle, 11, nut, 12, dust ring, 13, spring, 14, inipple, 15, through hole, 16, aperture.
Embodiment:
This plunger type derrick telescopic oil cylinder is made of flange 1, plunger 2, guide pin bushing 3, cylinder body 4, air relief cock 5, one-way valve 7, nut 11 and inipple 14.Be set with a cylinder body that can slide 4 on the plunger 2 thereon, the bottom of plunger 2 is shaped on and the fixing flange 1 of derrick lower body, and spring 13 and one-way valve 7 are equipped with in the bottom centre of plunger 2.One-way valve 7 axially on be shaped on a through hole 15, the footpath upwards is evenly equipped with 4 apertures 16.Plunger 2 two ends between plunger 2 and the cylinder body 4 respectively are provided with a guide pin bushing 3, guiding when guide pin bushing 3 plays cylinder body 4 and slides on plunger 2.Packing ring 8, seal ring b9 and O shape circle 10 are equipped with in the bottom of cylinder body 4.And fixing by nut 11, dust ring 12 is housed on the nut 11.Air relief cock 5 is equipped with at cylinder body 4 tops.Air relief cock 5 bleeds off gas in the cylinder body 4 when playing oil-feed.After plunger 2 can be divided into several sections processing, adopt inipple 14 to be formed by connecting, greatly reduce the difficulty of processing of plunger 2, the joint of inipple 14 two ends and plunger 2 is respectively arranged with seal ring a6 (referring to accompanying drawing).
This plunger type derrick telescopic oil cylinder is fixed with the derrick lower body by the flange 1 of plunger 2 bottoms, cylinder body 4 tops are installed an end and the derrick upper body of air relief cock 5 and are fixed, when on will making the derrick upper body, rising, oil feed line oil supply oil supply cylinder, spring 13 compressions are opened one-way valve 7, at this moment, 4 apertures 16 that through hole 15 on the one-way valve 7 and footpath make progress are totally 5 hole oil-feeds simultaneously, and cylinder body 4 drives on the derrick upper body and rises.When in the cylinder body 4 air being arranged, the gas in the cylinder body 4 is bled off by air relief cock 5.After operation is finished, in the time of regaining the derrick upper body, close oil feed line, the derrick upper body begins to fall, and spring 13 opens, and makes one-way valve 7 returns, 4 apertures 16 that this moment, the footpath made progress are sealed, through hole 15 oil returns on the one-way valve 7, and cylinder body 4 withdrawals drive the derrick upper body and regain.Owing to be provided with one-way valve 7 at the filler opening place of plunger 2,,, guaranteed operator and device security even the oil pipe explosion the phenomenon that oil cylinder and derrick fall rapidly can not occur yet if in-line goes wrong.
