Description
Technical field
The utility model relates to the accumulator manufacturing technology field of hydraulic machinery, specifically refers to a kind of ancient cooking vessel formula accumulator that supports three oil cylinders that has.
Background technique
Accumulator is a kind of auxiliary device more common in hydraulic system, in modern hydraulic machinery, has all used accumulator.It has the functions such as stored energy, steady pressure, compensation capacity, impact-absorbing, elimination vibration.Usually accumulator has capsule-type, piston type or other patterns.The capsule-type accumulator is to consist of fluid part and aerated capsule separator, utilizes the compressibility of gas to carry out energy accumulation.Hydraulic system is equipped it, both can play voltage stabilizing, buffering and Noise Reduction, can save a large amount of energy again, thereby be used widely.Common capsule-type accumulator, its working principle is to make the capsule contraction or expansion by the gas that is stressed in the accumulator housing, makes hydraulic system keep normal working pressure to reach the piston slided movingly with it and normally moves.Certainly the accumulator technical development up till now, has various ways, but, along with big machinery especially engineering machinery is more and more urgent to the demand of accumulator, therefore the accumulator of energy multiaspect work is gained great popularity.For example, " the shield structure " used in building subway, tunnel piercing, need to synchronously carry out the driving cutter support of rotary cutting.This class machinery all adopted several single hydraulic jacks to support in the past, although also can achieve the goal, asynchrony phenomenon occurred sometimes unavoidably, need to be regulated one by one.In view of the foregoing, the applicant has developed a kind of accumulator that supports three oil cylinders that has, and can guarantee the piston synchronous operation of each oil cylinder, guarantees the normal operation of power unit.
Summary of the invention
Technical problem to be solved in the utility model is to overcome in existing hydraulic machinery the defect of using a plurality of oil cylinders and can not the synchronization modulation oil cylinder piston, for large-scale engineering machinery provides a kind of three ancient cooking vessel formula accumulators that are mutually the form of standing like the legs of a tripod of 120 ° that have, with piston and the piston rod synchronous operation of guaranteeing its three oil cylinders.
The technological scheme of the utility model technical solution problem is: a kind of ancient cooking vessel formula accumulator, three sides that are the connecting base interval of positive six prisms at, radial arranges three oil cylinders that are mutually 120 °, the described connecting base top capsule-type accumulator main body that spins, described main body comprises housing, oiling valve and capsule, described housing is established capsule in top, and the bottom of described housing arranges oiling valve.
Described three oil cylinders connecting tube and connecting base by separately respectively spin, and described connecting tube is provided with hydraulic interface and is communicated with hydraulic pipe line, is provided with piston and piston rod in described oil cylinder, and the piston outside communicates with fuel tank, makes unnecessary fluid can get back to fuel tank.
Described oiling valve comprises poppet valve core, Returnning spring and valve seat, the top cover of described poppet valve core covers the filler opening of oiling valve valve seat, be provided with supporting ring around described valve seat, valve seat is connected with housing seal with Sealing by supporting ring, the valve seat outer surface is provided with screw thread, be screwed on the interface of connecting base end face, the valve seat side is provided with outlet valve.
The utility model is useful: because connect three oil cylinder and pistons that become the tripartite confrontation states on same a connecting seat, and regulated and controled by same accumulator simultaneously, so three pistons bear uniform pressure, thus can be simultaneously, with pressing operation.This can carry out rightly work when some occasion is used, and gives stably to support.The principle of the invention is equally applicable to two or three above a plurality of oil cylinders and the multichannel accumulator of piston.
The accompanying drawing explanation
Fig. 1 is the schematic diagram that connecting base of the present utility model and three oil cylinders become the tripartite confrontation state;
Fig. 2 is that in Fig. 1, the A-A direction is analysed and observe (the accumulator lower body part is analysed and observe) schematic diagram;
Each title and numbering in figure: 1-connecting base, 2-connecting tube, 3-oil cylinder, 4-piston, 5-piston rod, 6-hydraulic interface, 7-capsule, 8-poppet valve core, 9-Returnning spring, 10-housing, 11-supporting ring, 12-valve seat, 13-outlet valve.
Embodiment
As depicted in figs. 1 and 2, the utility model is a kind of ancient cooking vessel formula accumulator, and it is, at three side radials that are connecting base 1 interval of positive six prisms, three oil cylinders 3 that are mutually 120 ° are set, and capsule-type accumulator main body spins at connecting base 1 top.Main body comprises housing 10, oiling valve and capsule 7, and capsule 7 is located at housing 10 internal upper parts, and the bottom of housing 10 arranges oiling valve.Three oil cylinders 3 connecting tube 2 by separately respectively spin with connecting base 1.Connecting tube 2 is provided with hydraulic interface 6 and is communicated with hydraulic pipe line.Be provided with piston 4 and piston rod 5 in oil cylinder 3, piston 4 place oil cylinders 3 communicate with fuel tank, make unnecessary fluid can get back to fuel tank.Oiling valve comprises poppet valve core 8, Returnning spring 9 and valve seat 12.The top cover of poppet valve core 8 covers valve seat 12 filler openings of oiling valve, is provided with supporting ring 11 around valve seat 12, and valve seat 12 is tightly connected by supporting ring 11 and Sealing and housing 10.Valve seat 12 interface internal surfaces are provided with internal thread, are screwed on the joint of connecting base 1 end face, and the valve seat side is provided with outlet valve 13.
Below the running principle of the utility model product is described in detail again: the capsule 7 of housing 10 internal upper parts of accumulator main body is filled with the nitrogen of certain pressure.Work is first opened the outlet valve 13 of valve seat side before starting, and air remaining in hydraulic system is drained, and then closes outlet valve 13.The hydraulic oil of now coming from hydraulic system enters the oil pocket of body shell 10 interior bottoms from the passage between oiling valve and poppet valve core 8.Because body shell 10 tops are provided with the capsule 7 that is full of high pressure nitrogen, capsule 7 is subject to the hydraulic oil compressing and compressed, and now the interior gas pressure of capsule 7 becomes state of equilibrium with the hydraulic oil in the interior bottom of housing 10 and oil cylinder 3.When hydraulic system is carried out work, operating console sends instruction to solenoid valve, and the pressure oil of hydraulic system is given housing 10 interior bottom oil pocket and oil cylinder 3 input hydraulic pressure oil by pipeline simultaneously, and capsule 7 by compression and internal pressure raises.And, when hydraulic system pressure has downward trend, in order to maintain the pressure stability of oil cylinder 3, capsule 7 swelling pressures go out hydraulic oil, make hydraulic fluid pressure remain at a certain setting value.The hydraulic oil of hydraulic system outwards moves with piston rod 5 with setting pressure promotion piston 4 simultaneously, and piston rod 5 promotes mechanical workpiece again, can reach the purpose of regulation and control mechanical part.Because three pistons 4 are subject to an accumulator main body control with piston rod 5 is same, so its thrust be subject to is identical, thereby can realize tripodia synchronous operation.
