Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1,2, the present invention includes 2 two principal assemblies of buoyancy tank caterpillar track swamp vehicle 1 and weight focus, buoyancy tank caterpillar track swamp vehicle 1 comprises buoyancy tank 3, engine and hydraulic pump assembly 4, walk motor with hydraulic pressure 5, driving shaft 6, chain rail chain drive system 7, pilothouse 8, hydraulic reservoir and tank assembly 9, buoyancy tank ballast water plumbing pump 10, ballast tank 11 etc.
Weight focus 2 comprises weight 12, weight lift cylinder 13, weight compression cylinder 14, high pressure nitrogen gas bomb 15, weight focus outside framework 16, the dull and stereotyped lift cylinder 17 of weight, impacts flat board 18, weight canvas 19 etc.
The left and right sides buoyancy tank 3 of buoyancy tank caterpillar track swamp vehicle 1 provides car load buoyancy on the water, also is the bearing structure of car load simultaneously.The walking of buoyancy tank caterpillar track swamp vehicle 1 drives left and right sides walk motor with hydraulic pressure 5, driving shaft 6 and chain rail chain drive system 7 by engine and hydraulic pump assembly 4 and finishes.Engine and hydraulic pump assembly 4 also provide hydraulic power for weight lift cylinder 13, the dull and stereotyped lift cylinder 17 of weight.
Weight focus outside framework 16 is connected and fixed with the inboard girder of buoyancy tank 3.Buoyancy tank caterpillar track swamp vehicle 1 by the dull and stereotyped lift cylinder 17 of control weight, will impact dull and stereotyped 18 and rise to upper limit when sea, beach and floating walking, and the ground clearance of machine of car load increases, and the cross-country trafficability characteristic of car load improves.When arriving, the weight focus excites shot point, in the time of need to carrying out the epicenter excitation operation, by the dull and stereotyped lift cylinder 17 of control weight, make and impact dull and stereotyped 18 compacting earth's surfaces, buoyancy tank caterpillar track swamp vehicle 1 will be by jack-up, such as Fig. 2, the total weight of car load is loaded in the impact dull and stereotyped 18, to guarantee when weight 12 impacts operation the good coupling of impacting flat board 18 and earth's surface, the coupling effect that impacts flat board 18 and earth's surface directly affects the down biography of focus impact energy, affects the quality of seismic data.
Control weight lift cylinder 13 rises to upper limit with weight 12, and weight 12 tops link to each other with weight compression cylinder 14, and the nitrogen in the compression cylinder, weight are in preparation triggering state.The working pressure of nitrogen cylinder can be passed through to regulate the outlet valve pressure of the high-pressure nitrogen bottle that links to each other with compression cylinder to preset value.Usually the gas storage pressure of nitrogen cylinder is about 3000psi, and the working pressure of nitrogen cylinder is about 700-1500psi.Excite operation to start simultaneously the instrument record seismic data by the control trigger switch.
When the operation of Very Shallow Water area, when the depth of water during in the 1-1.5m left and right sides, water will be offset part car load ballast to the buoyancy of buoyancy tank 3, in order to guarantee to impact the good coupling on flat board 18 and earth's surface, in buoyancy tank 3 indoor designs ballast tank 11, buoyancy tank ballast water plumbing pump 10 places on the buoyancy tank caterpillar track swamp vehicle platform, when needing to increase the ballast of car load, with plumbing pump 10 seawater is pumped into ballast tank 11, when finishing the focus operation and need to remove some walking, with plumbing pump 10 seawater in the ballast tank 11 is pumped.
The present invention also adopts following technology contents:
The dull and stereotyped sealed attachment of weight canvas 19 bottoms and weight, top is fixed to buoyancy tank caterpillar track swamp vehicle upper mounting plate place, makes weight part and seawater isolation, prevents the weight corrosion or produces the percussive pressure water resistance.
Tension weight churning flat board 18 can be designed to the folding and expanding formula, and is deployable when needed, adds the contact area on massive plate and earth's surface.
