Description
Technical field
The utility model is related to a kind of measurement apparatus, and the gravity that more particularly to a kind of height and direction are freely set is vertically terraced
Measurement apparatus is spent, it can meet vertical gradient measurement demand during absolute gravity measurement, can also be applied to other height and side
The scientific research and testing set to freely adjusting.
Background technology
Currently in gravity measurement field, in order to obtain the vertical gradient of gravity of a certain position, usually using two high accuracy
Relative gravity meter device, it is one high and one low to observe simultaneously, then exchange two instrumented sites and observe repeatedly, obtain height point-to-point transmission
Shanxi Province after again divided by the discrepancy in elevation tries to achieve vertical gradient of gravity value.In the measurement process of vertical gradient of gravity, it is desirable to measure
Device is reliable and stable, and the instrument discrepancy in elevation can be adjusted freely and fixed up and down.
At present, vertical gradient of gravity measurement apparatus mainly has two kinds of forms, and one kind is superposing type, and metal stool is fabricated to
The different height size such as 20cm, 40cm, 60cm, is stacked when using according to height requirement, and the measurement height of this method is only
Restriction is several, and measurement angle can not freely be set, it is impossible to realize the continuous adjustment to measurement height and direction, operational group during measurement
Close complicated, not portable, stability is poor；Another is to utilize to measure tripod, and the base of relative gravity instrument is fixed on into three pin
It is observed on frame, although solve the problems, such as height adjustment, but when height is set, needs overall set up again to measure tripod, if
Put measurement highly cumbersome, it is difficult to fully meet height and the free setting requirements of angle, and part can only be met with connecting firmly dress
The gravimeter put is used, poor universality, and the bearing capacity of tripod is limited, is lacked necessary safety precautions, is unfavorable for gravity
The extensive use of vertical gradient measurement.
The content of the invention
In order to solve problem of the prior art, a kind of height of the utility model design and direction continuously adjustabe and freely set

It is connected between the top of tripod support column and lifting column on Y type support frames, described Y type support frames and sets tight
Lock screw.
The bottom of tripod support column is provided with Y type stable bases.
The vertical gradient of gravity measurement apparatus that a kind of height of the present utility model and direction are freely set, by typical tripod
Wooden or Light Aluminum Alloy material three support columns, are replaced by stainless steel, enhance the bearing capacity of tripod, are realizing
On the basis of height continuously adjustabe, the inside and outside pillar of each support column is respectively designed with embedded zigzag antiskid groove and
Connect firmly lock-screw, it is ensured that measurement height continuously adjustabe in the range of 70cm~160cm, meanwhile, the inside and outside branch of tripod can be prevented
Post slides or threads off and cause observation instrument to be dropped.The quarter of expansion link collapsing length is designed on each support column of tripod
Line is spent, the quick measurement for setting and being fixed to a certain needs is highly located when being convenient for measuring, and is not required to measure the height of measurement apparatus in addition
Degree, the convenience that intensifier is used.
One, which is designed, on the base of triangle top of support is spirally freely lifted pallet, the design connection gravimeter on pallet
Connecting screw.Gravimeter base is fixed on pallet during measurement, the connecting pole periphery design screw thread under pallet, on internal surface of sleeve pipe
It is designed to being connected the screw thread mouth that male screw is tightly engaged.When pallet and connecting pole turn clockwise, pallet just declines；Conversely,
During rotate counterclockwise, pallet just rises, and adjustable height reaches 15cm, so as to accurate adjustment gravimeter measurement point height.Pallet
It can arbitrarily be adjusted on 360 ° of directions of level, meet vertical gradient of gravity height and direction continuously adjustabe and accurately freely set
Measurement request.
Arc measurement guard rail is designed on base, the guard rail is designed to semicircle, is connected on tripod top surface, measures
When protection instrument prevent its slide or topple over, windbreak function when also functioning to gravity measurement.Guard rail and tripod top surface face
Plate is connected using plug-in, can freely be removed and installed, is convenient for carrying.
The circular level(l)ing bubble of design and installation is gone back above base, facilitates outline to flatten foot stool top surface.Three supports of tripod
Post is averagely laid out in the bottom of tripod top surface, can free opening and closing, using can between three support columns and the sleeve pipe of top surface bottom
The Y type support frames of opening and closing folding and unfolding, by the angle of three support intercolumniations of position-adjustable of the adjustable Y-shaped support frame on sleeve pipe,
Can outline flatten the pallet of tripod top surface, the tight lock screw of Y type support frames is locked after the completion of regulation so that fixed tripod,
Strengthen the bearing capacity and security of foot stool.After being measured, Y type support frames are upwards collected through, tripod can be packed up freely, it is convenient
Carry.
The beneficial effect brought of technical scheme that the utility model is provided is：
1st, it is applied widely
This be applicable it is new can be applied to indoor environment and field operation environment, can be used on the point position of handpan, also
It can be applied to the general ground in field；The scope highly continuously adjusted is big, height change model when can meet absolute gravity measurement
The vertical gradient measurement demand for 70cm~160cm is enclosed, can also be applied to other height and direction needs the scientific research freely adjusted to try
Test；Design pressure connecting screw of the connecting base plate of different instruments all with measurement apparatus to be directly fixedly linked, can meet various
The use requirement of active service relative gravity instrument.
2nd, measurement height and horizontal direction can freely be set
Telescopic tripod support bar, Y types support frame and the spiral design for being freely lifted the parts such as pallet of device,
After the initial position of fixed Y type support frames is fixed, tripod supports the distance of intercolumniation just to secure two-by-two, so that three supports
Post can be fixed in the radius of circle that ground level is formed, thus can use the total length of support column and the radius of circle of baseplane, essence
The height of measurement apparatus is really calculated, the height sign that measurement apparatus thus can be accurately scribed in the interior bar of support column is carved
Line, so as to the measurement height of quick adjustment measurement apparatus, precise height is adjusted to required survey using spiral lift pallet
Amount height and angle, reach height and direction continuously adjustabe and the measurement request freely set.
3rd, security and stability is good
The design of the parts such as the tight lock assembly of tripod, Y types support frame, guard rail so that the peace of gradiometry device
Total stability is greatly improved.In ground grading in use, Y type stable bases can be laid on ground, fixed tripod two is played
Two support intercolumniation ground distances and the effect of anti-sliding stop, also greatly improved the bearing capacity of measurement apparatus, enhance device
Security and stability.
