Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly relates to a kind of hydraulic elevating system.
Background technique
Hydraulic elevating system is the elevator mechanism the most common adopted in existing main equipment, and its principle changes depth pistion by hydraulic oil.Existing hydraulic elevating system generally comprises hydraulic cylinder and is slidably arranged in the piston in hydraulic cylinder, and be arranged on the cylinder body bottom at hydraulic cylinder lower ending opening place, cylinder body bottom offers hydraulic oil channel, and between piston side and hydraulic cylinder, location and installation has oil sealing; During use, hydraulic oil channel connects hydraulic oil unit, by changing the hydraulic oil oil level of piston lower portion, realizes moving axially of piston.But the oil sealing sealing poor effect of existing hydraulic elevating system, when hydraulic oil pressure is excessive, often there will be oil impregnate phenomenon.
Summary of the invention
In order to solve the problem, the purpose of this utility model is the hydraulic elevating system providing a kind of good sealing effect.
In order to realize above-mentioned object, the utility model have employed following technological scheme:
Hydraulic elevating system, comprises hydraulic cylinder, and to be arranged in hydraulic cylinder and can piston in axial sliding, and is fixed on the cylinder body bottom at hydraulic cylinder lower ending opening place; Described cylinder body bottom is provided with hydraulic oil channel, and the inner opening of hydraulic oil channel is on cylinder body bottom end face, and the outer end opening of hydraulic oil channel is on cylinder body bottom side; Be provided with guidance tape and O-ring seals between described piston and hydraulic cylinder upper end portion, between piston and hydraulic cylinder underpart, be provided with that lower guidance tape and V-arrangement are folded to be sealed successively; Described upper guidance tape and lower guidance tape interference are arranged between hydraulic cylinder and piston, and the V-arrangement that V-arrangement folds envelope is opening down.
As preferably, described upper guidance tape and the equal location and installation of O-ring seals are in the interior sidewall surface of hydraulic cylinder.
As preferably, the inside center place of described cylinder body bottom is provided with the displacement transducer for detecting piston position, and the upper end portion of displacement transducer is located in piston centre place; Displacement transducer for monitoring depth pistion, and is transferred in middle control computer with data mode.
The utility model adopts technique scheme, is provided with that O-ring seals, V-arrangement folded seal, upper guidance tape and lower guidance tape between the piston of this hydraulic elevating system and hydraulic cylinder; O-ring seals flows in hydraulic cylinder for preventing the lubricant oil of hydraulic elevating system outside; Upper guidance tape and lower guidance tape are used for the relative movement between guide piston and hydraulic cylinder, and can prevent piston from directly contacting with hydraulic cylinder, wearing and tearing; V-arrangement is folded envelope and is used for preventing hydraulic oil seepage, maintain stability hydraulic, the V-arrangement that V-arrangement folds envelope is opening down, namely V-arrangement folds the V-arrangement opening of envelope towards hydraulic oil, under the effect of hydraulic oil V-arrangement opening can extended, open, thus make the interference of V-arrangement folded envelope be arranged between hydraulic cylinder and piston, better tightness.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
A kind of hydraulic elevating system as shown in Figure 1, comprises hydraulic cylinder 71, and be located at hydraulic cylinder 71 can the piston 72 of axially lower slider, and be fixed on the cylinder body bottom 73 at hydraulic cylinder 71 lower ending opening place; Cylinder body bottom 73 is provided with hydraulic oil channel 731, and the inner opening of hydraulic oil channel 731 is on cylinder body bottom 73 end face, and the outer end opening of hydraulic oil channel 731 is in cylinder body bottom 73 side.During use, hydraulic oil channel 731 connects hydraulic oil unit by oil pipe, by the hydraulic pressure oil level below hydraulic oil unit control piston 72, thus changes the height of piston.Cylinder body bottom 73 inside center place is also provided with the displacement transducer 74 for detecting piston 72 height, and displacement transducer 74 is connected with middle control computer, and the upper end portion of displacement transducer 74 is located in piston 72 center.
Be provided with guidance tape 75 and O-ring seals 76 from top to bottom successively between piston 72 and hydraulic cylinder 71 upper end portion, upper guidance tape 75 and O-ring seals 76 are all located on hydraulic cylinder 71.Be provided with lower guidance tape 77 from top to bottom successively between piston 72 and hydraulic cylinder 71 underpart and V-arrangement folds envelope 78, the V-arrangement that V-arrangement folds envelope 78 is opening down.Described upper guidance tape 75 and the interference of lower guidance tape 77 are arranged between hydraulic cylinder 71 and piston 72, make hydraulic cylinder 71 and piston 72 there is gap between the two, prevent piston 72 from directly contacting with hydraulic cylinder 71, wearing and tearing; O-ring seals 76 is for preventing upper end lubricant oil dirty; V-arrangement folds envelope 78 for the gap between sealed hydraulic cylinder body 71 and piston 72 lower end, for preventing hydraulic oil seepage, maintain stability hydraulic, the V-arrangement that V-arrangement folds envelope 78 is opening down, namely V-arrangement opening is towards hydraulic oil, under the effect of hydraulic oil V-arrangement opening can extended, open, thus make V-arrangement fold envelope 78 interference to be arranged between hydraulic cylinder 71 and piston 72, better tightness.
