Description
Technical field
The utility model relates to oil seismic exploration equipment technology field, particularly a kind of earthquake source.It is a kind of hydraulic servo oil cylinder of controlled source.
Background technique
The main flow controlled source that oil seismic exploration is used loads the hydraulic servo vibrator by cross-country carriage chassis to be formed, and vibrator is by reaction hydraulic servo oil cylinder and dull and stereotyped the composition.During the controlled source construction, by the lifting hydraulic jack vibrator is positioned on the ground, reaction force by the lifting hydraulic jack is pressed in the weight of car body on the flat board simultaneously, prevent the coupling on dull and stereotyped disengaging and ground, dull and stereotyped and piston rod is rigidly connected, and the to-and-fro motion generation that is driven cylinder body (reaction weight) by electronic control system control hydraulic efficiency servo-valve shakes continuously.
Consult Fig. 1.Traditional reaction servo-cylinder sealing configuration is: the hydraulic oil in servovalve A chamber enters the epicoele of servo-cylinder by oil duct a, b, c, d, e, the hydraulic oil of servo-cylinder cavity of resorption is got back to the B chamber of servovalve by another oil duct of respective sequence, otherwise the oil-feed of B chamber and the oil return of A chamber alternately realize vibrations so repeatedly.The pressure oil of servo-cylinder epicoele, cavity of resorption produces leakage by the matching gap between piston rod 1 and interior copper sheathing 2, outer copper sheathing 9, the sealing gland 5, therefore the two seals structure that seal ring 6 and seal ring 7 are formed has been installed on the copper sheathing 9 outside, at skin dust ring 8 has been installed and is prevented that pollutants such as dust, water from entering.Sealing gland 5 adopts a circle high-strength bolt to tighten up with cylinder body 3.
The environment facies of controlled source work are when abominable, and as Gobi desert, shallow desert, mountain front and cold ice and snow area etc., ambient dust is many, the temperature difference is big, makes be difficult to control the working life of servo-cylinder Sealing, and replacing is more frequent sometimes.
When traditional reaction servo-cylinder is changed Sealing, the circle of one on the sealing gland 5 high-strength bolt be need unload, sealing gland 5 and outer copper sheathing 9 replacing Sealings taken off then.On the sealing gland 5 one circle high-strength bolt bears the huge reaction force that servo-cylinder produces, the specification of bolt is bigger and quantity is many, in order to prevent the loosening screw thread fastening glue and fastening that on bolt, is coated with usually of vibrations with torque wrench, and the weight of sealing gland 5 itself is also bigger, need the number people to finish inefficiency during dismounting.
The model utility content
The purpose of this utility model is: a kind of reaction hydraulic servo sealed cylinder is provided, improves the maintainalbility of controlled source reaction servo-cylinder, increase work efficiency and improve the sealability of oil cylinder.
The technical solution adopted in the utility model is: reaction hydraulic servo sealed cylinder, mainly by piston rod, interior copper sheathing, cylinder body, cylinder sleeve, sealing gland, the first road seal ring, the second road seal ring, dust ring, outer copper sheathing and dull and stereotyped the composition;
Piston rod is vertically fixed on the flat board.There is piston at the piston rod middle part, is with cylinder sleeve in the piston outside, in the outside of cylinder sleeve cylinder body is arranged, and interior copper sheathing is arranged two ends respectively up and down in cylinder body and at cylinder sleeve, the center hole of copper sheathing in piston rod passes.Two highly pressurised liquid access ways are arranged, a highly pressurised liquid access way UNICOM piston upper chamber, another highly pressurised liquid access way UNICOM piston cavity of resorption on cylinder body and interior copper sheathing.
It is characterized in that: be fixed with sealing gland respectively at the cylinder body two ends, adopt bolt fixing between sealing gland and the cylinder body.Fixing bolt bears the huge reaction force that servo-cylinder produces.The plane of sealing gland is pressed on the outer Transverse plane of interior copper sheathing.Annular space internal fixation between sealing gland and piston rod has copper sheathing outside the cylinder bodily form, on the outer copper sheathing outer wall flange is arranged, and outer copper sheathing is fixed by flange and sealing gland.Two seals circle and dust ring are arranged on the copper sheathing outside.
The position of described two seals circle and dust ring is: outer copper sheathing has center hole, and is fluted in the copper sheathing center hole outside, and the second road seal ring is arranged in the groove of outer copper sheathing center hole; There is groove copper sheathing center hole the inner outside, in the end slot the first road seal ring is arranged in the outer copper sheathing center hole; There is groove copper sheathing center hole outer end outside, in the outer end slot of outer copper sheathing center hole dust ring is arranged.
The beneficial effects of the utility model: the utility model reaction hydraulic servo sealed cylinder, when needs are changed Sealing, only need the circle stove bolt on the lighter outer copper sheathing of dismounting weight, take off outer copper sheathing then and just can change Sealing, improve working efficiency, and improved the sealability of oil cylinder.
