The basis of bar piston component 1 is internal forms axial passage 3 along its whole length, and described axial passage is in the part near described plate 2
In have local wide portion, thus form cylindrical cavity 4, and the piston of connecting rod piston assembly 1 be placed on the hydraulic cylinder with top cover 6
The basis of 5 is internal, and hydraulic cylinder 5 is separated by dividing plate 8 with bottom pneumatic chamber 7, and described plate 2 is arranged in bottom pneumatic chamber 7；Described plate
2 are interacted by the upper end with sealing ring 9 of its lower end and stepped cylindrical waveguide 10 forming pneumatic gripping device, institute
State the major diameter of waveguide to top bar and 11 be positioned at described pneumatic chamber 7, get out of a predicament or an embarrassing situation 12 and gas at lower end equipped with working plate 13
The bottom 14 of dynamic room 7 forms damping cavity 15；Described cylindrical cavity 4 is connected to pneumatic chamber 7 by radial passage 16, and connecting rod 17 is set
Putting in described axial passage 3 and have the potted component 18 being secured to its lower end, this potted component can be with cylindrical cavity 4 times
Seat 19 at end interacts, the upper end of connecting rod 17 be arranged on rigidly attached in connecting rod piston assembly upper end and include dish base
In the valve casing of seat 20 and lid 21, the upper end of connecting rod 17 is equipped with the disc 22 being spring loaded relative to described pedestal 20, and has
Having barrier film 23, barrier film 23 is sandwiched between dish pedestal 19 and lid 21 around its periphery.Spring 24 is arranged in valve casing, described
Device is used for supplying air and working fluid equipped with passage 25,26,27,28,29 and 30.
Described device described works by following.Before operation, pneumatic chamber 7 and damping cavity 15 are respectively by passage 26
Be filled into 1.0(10 with 27 with air) to 1.5(15) Mpa(atm) and pressure.After this device is placed on the ground, compression
Air by passage 25 through Controlled valve (not shown) is provided to dished lid 21 from receptor and barrier film 23 is formed chamber.
By compression spring 24, connecting rod 17 moves down, and potted component 18 leans against on seat 19.Then, the lower chamber of hydraulic cylinder 5 is led to
Crossing passage 28 and connect to carry out pressure release, and working fluid is fed to the upper chambers of hydraulic cylinder 5 by passage 29, therefore connecting rod is lived
Plug assembly 1 declines together with described plate 2, until on the sealing ring 9 of plate 2 end that leans against waveguide 10.Then, plate 2
With the air in the chamber (it is sealed relative to the inner space of pneumatic chamber 7) between the end face of waveguide 10 is through Controlled valve (in figure
Not shown) it is released in air by the passage 30 in connecting rod piston assembly 1, thus formed and there is rigid chain (connecting rod piston
Assembly 1-plate 2-waveguide 10) gas-operated lock.The upper chambers of hydraulic cylinder 5 is connected with pressure release subsequently, and is in the work under pressure
Make fluid and be supplied to the lower chamber of hydraulic cylinder 5 by passage 28, and connecting rod piston assembly 1 is together with plate 2 and waveguide 10
Move to upper position.Due to the diameter of connecting rod piston assembly 1 top bar than waveguide 10 11 diameter much smaller, the most pneumatic
Pressure in room 7 raises rapidly.(figure is seen after connecting rod piston assembly 1 arrives position, top side together with plate 2 and waveguide 10
2), passage 30 is sealed by Controlled valve, and compressed air enters air from the chamber between dished lid 21 and barrier film 23 through Controlled valve
In, connecting rod 17 moves up under the effect of spring 24；Air under high pressure goes to gas through radial passage 16 and cylindrical cavity 4
Dynamic lock, thus open gas-operated lock.Compressed air from pneumatic chamber 7 acts on the end face of waveguide 10, and this exists through working plate 13
Apply dynamic action on ground, thus produce seismic wave on the ground.Meanwhile, under compressed-air actuated effect, connecting rod piston group

Lead the active force on 10 equal time, waveguide 10 and working plate 13 depart from ground, and within a period of time they together with device
Miscellaneous part move up.After resilience, described device is smoothly declined by specific suspension system (not shown)
To ground, and cycle of operation is from the moment repetitive cycling supplying working fluid to the upper chambers of hydraulic cylinder 5.
Owing to the volume stroke little, connecting rod 17 controlling chamber between dished lid 20 and barrier film 23 is little and is used for pressing
Contracting air is short from the passage length of the gas-operated lock that pneumatic chamber 7 is delivered between the end face of plate 2 and waveguide 10, and the opening time is the longest.
Which ensure that from opening between the Time constant being sent to be produced the moment of ground dynamic load by working plate 13 of gas-operated lock signal
Every, say, that this makes described device to work asynchronously.The step shape of the piston of connecting rod piston assembly 1 can reduce
The net cycle time of device, thus improve work efficiency.This is because when the air pressure in pneumatic chamber 7 raises rapidly,
Needed for connecting rod piston assembly 1 and plate 2 are moved down in pneumatic chamber 7 required force rate connecting rod piston assembly 1 and plate 2 backstroke
Power much smaller.The movement resistance of connecting rod piston assembly 1 too increases.So, for identical working fluid nominal pressure values
For, the operating consumption of decline of connecting rod piston assembly 1 is reduced, and runs time and net cycle time the most significantly
Reduce.
