Solving the scheme that technical matters of the present utility model adopts is: in the two side that the rectangle fixed bin is vertical each other handwheel is housed respectively, gear is housed on the handwheel, the tooth bar of packing in the chute of fixed bin inner chamber setting, gearing mesh on tooth bar and the handwheel, and tooth bar is connected with coordinate axis end in lying in a horizontal plane in fixed bin, two vertical each other horizontal axis are passed the corresponding through hole of a coordinate axis fixed block respectively, vertical scale bar passes fixed block again and is fixed, and hall probe is fixed on the Vertical surveyors' staff bar.
The technical solution of the utility model also comprises:
Describedly be positioned at that the tooth bar of slippage adopts two-sided tooth bar in the chute, the tooth of a side and the gearing mesh on the handwheel, the tooth of opposite side is connected by engagement with the gear of coordinate axis end.
In this magnetic-field measurement orientator, horizontally disposed X coordinate axis and Y coordinate axis all respectively are provided with two, and the gear of coordinate axis end all is provided with tooth bar in both sides up and down, can reduce swing like this when instrument is worked, and improve measure accurate greatly.
On the handwheel of this device, fixed bin and vertical scale bar, all be processed with scale mark, fixed bin respective coordinates axle isometry position has level trough, the indicateing arm that is fixed on the coordinate axis extends level trough by the scale mark of fixed bin, therefore can recognize the three-dimensional accurately position of hall probe in operation easily.
When operation, orientator is placed on the flange of crystallizer top, the center that makes the center of hollow position of fixed bin and crystallizer copper pipe is on same pedal line, rotate the handwheel of corresponding X coordinate axis then, make with handwheel between the gear rotation that cooperates with key, the tooth bar of gear driven and gearing mesh drives coordinate axis again and moves, scale value on the handwheel is corresponding with the scale value on the fixed bin, can find out the directions X coordinate of scale bar at this moment; Therewith in like manner, Y is to handwheel in operation, determine that simultaneously the Y of scale bar is to coordinate, then hall probe is goed deep in the scale bar, the threaded hole screw-in screw from the scale bar below is fixed on 0 scale place on the scale bar with probe, scale bar is penetrated in the coordinate axis fixed block then, scale on the adjusting scale bar is up to the scale for needing to measure, but the right angle three like this then point that pinpoint need be measured is a coordinate, can produce a desired effect.
The beneficial effects of the utility model are: the hall probe of measuring with tesla's instrument is reached want the measuring position, can accurately locate, solve coarse problem of in the past locating, be the automanual system design owing to what adopt simultaneously, so when guaranteeing precision, it also is very simple using, and does not need the professional to manipulate, human resources have been saved, this apparatus structure compactness, volume is little, and is in light weight, easy to use flexible, and its serviceability is good, can finish the work smoothly, simultaneously owing to can not use permeability magnetic material, so use the organosilicon epoxy resin bonded fiber, the cloth rod is made, and environment is not had influence.
