Abstract
The utility model discloses an observing platform for gravity vertical gradient. The observing platform is composed of an observing rack, a horizontal adjustment base and a tripod, wherein, the observing rack is provided with a measuring scale fixing hole, a guard rail, a leveling bubble, a platform bottom plate, a connecting column and a height measuring scale. The observing platform has the advantages of simple structure, stable connection, quick leveling, light weight and easy and convenient disassembling and assembling. The utility model is suitable for the platform which carries out the gravity vertical gradient corresponding to a gravimeter and is convenient to be carried and used in field.
Description
Technical field:
The utility model relates to measurement mechanism, the observation platform when being used for the relative gravity instrument and making vertical gradient of gravity and measure.
Background technology:
In gravimetry and exploration geophysics, the height of vertical gradient of gravity accuracy of observation in absolute gravity measurement particularly, to directly have influence on the comparison of various types of absolute gravimeters accuracy of observation on same measurement point, and relate to the accuracy of relative gravity measurement net original bench mark.Existing vertical gradient of gravity measurement mechanism is made up of observation platform, horizontal adjusting machine base and tripod, and observation platform mainly contains the tower or column of frame-type, and its weak point is, complex structure, not quick detachable and installation; Perhaps observation inconvenience, measuring accuracy is low.
Summary of the invention:
The purpose of this utility model is, a kind of vertical gradient of gravity observation platform is provided, be used for the relative gravity instrument and carry out the platform of vertical gradient of gravity when measuring, that this observation platform has is simple in structure, connect and stablize, put the advantage that level is fast, in light weight, dismounting is easy, is convenient to the field and carries and use.In order to achieve the above object, the utility model device by the following technical solutions: a kind of vertical gradient of gravity observation platform is made up of observation platform, horizontal adjusting machine base and tripod, and wherein horizontal adjusting machine base and tripod are prior art.
Observation platform is made up of scale fixed orifice, guardrail, horizontalization bubble, platform floor, joint pin and the high scale of survey.Platform floor is a square, and is fixing respectively on its four angles
The type guardrail, each
A scale fixed orifice is set on the type guardrail, circular horizontalization bubble is installed in center on platform floor, joint pin is fixed on the Centromedian below of platform floor, joint pin and platform floor junction are cylindrical, its other end has three pin corresponding to three connecting holes on the horizontal adjusting machine base, surveys high scale and is placed in
On the type guardrail in any one scale fixed orifice.
Three pin of the joint pin on the observation platform are inserted in three connecting holes on the horizontal leveling support, and the twisting check lock lever will be measured connecting screw rod on the tripod again and be connected with nut on the horizontal leveling support and tighten up.
For generation that prevents magnetization phenomenon and the weight that alleviates the vertical gradient of gravity observation platform, all parts adopt non-ferrous metal, and the semiclosed guardrail on observation platform is used to place gravity meter, increase the safety coefficient of instrument, avoided instrument to fall the generation of damage incident.Survey high scale and can measure ground exactly, improve measuring accuracy to the height between the vertical gradient of gravity observation platform.When gradiometry, LCR-G (D) type gravity meter is placed on horizontalization on the ground, after the value, instrument is placed on the observation platform, with the gravity meter horizontalization, can carry out and finish the surveying work of gravity gradient by the horizontalization turn-knob fast.
The utility model compared with prior art has the following advantages and effect: simple in structure, be connected and stablize, put that level is fast, in light weight, dismounting is easy, and be convenient to the field and carry and use.
Description of drawings:
Fig. 1 is a vertical gradient of gravity observation platform front elevation.
Wherein: 10 is that observation platform, 20 is connecting screw rod for leveling turn-knob, 9 for surveying high scale, 7 for twisting check lock lever, 8 for joint pin, 6 for platform floor, 5 for horizontalization bubble, 4 for guardrail, 3 for scale fixed orifice, 2 for tripod, 1 for horizontal adjusting machine base, 30.
Fig. 2 is the vertical view of observation platform among Fig. 1.
Wherein: 2 is that guardrail, 3 is that horizontalization bubble, 4 is platform floor.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing: a kind of vertical gradient of gravity observation platform is made up of observation platform 10, horizontal adjusting machine base 20 and tripod 30.
Three pin of the joint pin on the observation platform 10 5 are inserted in three connecting holes on the horizontal leveling support 20, and twisting check lock lever 7 will be measured on connecting screw rod 9 and the horizontal leveling support on the tripod 30 20 nut again and be connected and tighten up.Leveling turn-knob 8 is used to adjust observation platform 10 horizontalitys.
