Abstract
The utility model relates to an integrated hydraulic power part. The utility model is characterized in that a front cover and a back cover of the original common hydraulic cylinder are enlarged. A thin pipe with large diameter held by an o-shaped sealing ring is used as an oil tank. A flexible air bag is used to adapt to the motion of the hydraulic cylinder, so that the volume of the oil in the oil tank is changed. The back cover of the oil tank is provided with a motor, a hydraulic pump, a pressure control valve and a reversing valve, wherein, the motor and the hydraulic pump can generate pressure oil, and the pressure control valve and the reversing valve are used to control pressure and the channel of the pressure oil. All components and attachment fittings of complete machine are integrated in the utility model. The integrated hydraulic power part has the advantage of simple structure, compact structure, reasonable structure, low cost, low energy consumption, reliable work, and no pollution. The integrated hydraulic power part is suitable for occasions requiring straight-line motion.
Description
The utility model relates to a kind of machinery, relates to particularly a kind ofly finishing straight-line hydraulic power parts.
The general now hydraulic power parts that adopt are split type, and the tube cylinder is in the same place with actuator, and fuel tank, oil hydraulic pump and motor are in the same place, and selector valve is in the same place with pressure controlled valve, links to each other with pipeline each other, use extremely inconvenient.Fuel tank is inside and outside gets in touch with atmosphere by netted, sieve shape thing, and it can allow air can see through its turnover fuel tank with dust every outside fuel tank, guarantee in the fuel tank not can because of the piston rod to-and-fro motion the vacuum that may occur or be with pressure.
The purpose of this utility model is to be split type according to present hydraulic power parts, and structurally remains the situation in some problems, is intended to design a kind of simple and reasonable for structure, low, free of contamination integral hydraulic power unit of power consumption.
The purpose of this utility model realizes that in the following manner the integral hydraulic power unit comprises motor 1, oil hydraulic pump 3, selector valve 4, piston rod 9, fuel tank 13, cylinder barrel 14.One fuel tank 13 that is made of the large diameter thin wall pipe is arranged outside common hydraulic cylinder 14, fuel tank 13 by behind the fuel tank, protecgulum 11,15 clampings, clamping place has the sealing of O RunddichtringO.The outer space of cylinder barrel is a fuel tank cavity, 12.The fuel tank top has a hole as trapping window 7, stretches into flexible airbag 8 sacks and the driving fit of limit, hole in the fuel tank cavity.Fuel tank bonnet 15 sidepieces stretch out the pressure regulation bar 5 of control oil hydraulic pump delivery pressure control valve.There are oil hydraulic pump 3 and selector valve 4 in fuel tank bonnet back with bolt, also has the support 2 of supporting motor 1.Motor and oil hydraulic pump 3 usefulness coupling 10 connect.
Accompanying drawing is the utility model structural representation.
With reference to accompanying drawing, the utility model is that the protecgulum of former common oil hydraulic cylinder letter 14, bonnet are enlarged, and double as is a fuel tank protecgulum 11, bonnet 15, and as fuel tank 13, the outer space of cylinder barrel is a cavity by O RunddichtringO clamping one major diameter light wall pipe.Fuel tank bonnet 15 not only is the part of oil pressure cylinder barrel and fuel tank, and is again the main body that control enters tank pressure oil oil circuit.Stretch into the flexible airbag 8 of fuel tank window cavity is made by the soft rubber or the nylon of tool opening and closing from trapping window 7, it can not only solve vacuum or the band pressure problem that former fuel tank causes along with the oil hydraulic cylinder motion, and it is equal with ambient pressure by the variation assurance fuel tank cavity pressure of its volume, no matter putting angle, fuel tank how to change in addition, pressure oil can not overflow from here, can also isolate fully with atmosphere, play antifouling effect.
When using the utility model, be fixed somewhere by installation shaft 6 earlier.Connect motor 1 power supply, motor drives oil hydraulic pump 3 by coupling 10 makes import suck fluid from the fuel tank cavity, the outlet pressure oil output.Connect selector valve 4 one end power supplys, oil hydraulic pump outlet pressure oil enters cylinder barrel 14 1 chambeies by selector valve, promotes piston rod 9 toward direction motion; Connect selector valve 4 the other end power supplys again, pressure oil enters cylinder barrel 14 another chambeies, promotes piston rod toward the opposite direction motion.When not needing piston rod to move, then disconnect selector valve two ends power supply.During shutdown, then disconnect motor power.
The utility model is an one with all units of complete machine, auxiliary collection, and simple and reasonable for structure, compact, cost is low.Pressure and flow and actuator adapt to fully, and energy consumption is low, reliable operation, environmentally safe.The utility model needs to realize that to all the occasion that straight line motion requires all is suitable for.
