2, air capacity 90L/min.
(2) impact system
Impact system is made up of 1 ram hammer, 14,1 impact pad, 15,4 impact pad guideposts 02, sees shown in Fig. 1 and Fig. 4.Impact pad guidepost 02 is fixedly connected with impact pad 15, impact pad guidepost 02 is enclosed among the sliding bearing of body frame, when ram hammer is applied to impact pad 15 downwards, move down under the control of guidepost thereupon, give the earth by impact pad 15 by impact shock energy going down.Impact pad 15 is circular, and form by three layers, its area increases successively, to increase impact pad and contact area greatly.Ground floor is high impact material, is expendable part, replaceable.Impact pad grab 13 is fixed on the second layer, and impact pad guidepost 02 is fixed in third layer.
(3) impact pad fastening system
Card 03 is fixed and 2 impact pad grabs 13 form primarily of 2 impact pads.The effect of impact pad grab 13 utilizes ram hammer movement upwards to promote impact pad 15, and hold impact pad 15 by the pressure that cylinder lower end maintains and do not glide.The effect that impact pad fixes card 03 is, when cylinder does not have air pressure, stuck impact pad guidepost 02, to prevent the natural downslide of impact pad 15, hinders the movement of focus instrument.When focus instrument works, impact pad be opened and fix card 03, make the smooth and easy slip of impact pad guidepost 02.And open impact pad grab 13, the ballistic motion of ram hammer can not be stopped.
Principle of work of the present invention is as follows:
Air pressure pump is utilized to carry out energy storage to blow cylinder.When pressure is to design load, the pressurized air of air storing cavity acts on piston suddenly, and drives the downward quick washing of steel hammer.When ram hammer bump against bottom impact backing plate time, just produce strong impulsive force, impact backing plate with the earth contact, backing plate under instant impact effect, generation source of seismic wave, seismic event centered by backing plate to underground propagation.
The course of work of the present invention is as follows:
Focus instrument moves (see Fig. 1):
1) focus instrument support 10 is packed up.
2) pinning impact pad 15 is promoted.
3) utilize bail 11 tractive focus instrument, after manually hold focus instrument frame handle.
Focus instrument work (see Fig. 2 and Fig. 6):
1) focal point position is arranged smooth, probably tamp.
2) earth surface met by drop impact pad 15.
3) focus instrument support is put down, make focus instrument basic horizontal.
4) open compression pump, make pressure reach ratings.
5) rotate air valve reversing switch, make ram hammer rise to peak.The now epicoele exhaust of cylinder, cavity of resorption air inlet, piston seals middle cover gas orifice.
6) rotate air valve reversing switch, make lower opening all air inlets on cylinder.Its effect allows the pressure of upper chamber of air cylinder be increased to rated pressure.
7) rotate air valve reversing switch, cylinder lower opening is vented and the continuation air inlet of upper hole.Now, the downward high speed impact of piston driving ram hammer, when impacting impact pad, just produces strong vibrations, gives the earth by impact pad by vibration energy going down.
8) by the 4th)-7) step, just complete one-shot vibration.
