Abstract

The utility model belongs to an accessory device of a measuring instrument, in particular relating to a theodolite fast centering device. The theodolite fast centering device consisting of a positioning ring 1, a centering needle 2, a fixing plate 3, a fixing wire 4, a spacer pin 5 and a positioning tube 6 with an end head 7 simplifies complicated centering debugging before the theodolite measures. When the circle center of the positioning ring 1 of the theodolite fast centering device of the utility model is overlapped with a measuring point, namely the measuring point is positioned at the center of a gap of the centering needle 2 fixed on the inner wall of the positioning ring 1. After the upper end of the positioning ring 1 is adjusted to be in a horizontal state and the positioning tube 6 is pulled to ensure the end head 7 of the positioning tube 6 to contact the same position of three legs of a tripod at the same length, the theodolite fast centering device can carry out measuring.

Description

The quick centralizer of transit

Technical field: the utility model belongs to a kind of auxiliary equipment of surveying instrument, especially relates to the quick centralizer of a kind of transit.

Background technology: transit is as a kind of surveying instrument, because its volume is lighter, is convenient to install demolition and carries, and measures accurately, so in the generally use already of every field such as building operation, water conservancy and farmland capital construction, means of transportation, planning and design.During practical operation, centering (being about to the center of measurement point on the vertical corresponding ground of centre) is crucial, usually way is the top that the tripod of tripod separately is placed on ground survey point by the operation height, and make the measurement point of hanging on the point that the line in the tripod hook weighs down is tried one's best corresponding ground, fastening foot rest fixed screw; After transit is fixedly mounted on foot rest top, adjusts three foot screws of instrument and make the circular bubble bubble placed in the middle, observe, adjust eyepiece, make the centering scale mark clear by the centralizer eyepiece; Adjust the focusing handwheel of centralizer, until ground survey sign center clear and with the centering scale mark in same imaging plane; Unclamp the foot rest center bolt, observe surface mark by optical centering device, parallel mobile instrument overlaps with the surface mark center up to the centering center of reticule; Adjust foot screw again, make the bubble of circular bubble placed in the middle; Again by optical centering device, check whether surface mark hangs down with the centralizer center to close, otherwise repeat above-mentioned part operation again, until surface mark under horizontality with till the centralizer center overlaps.Visible from the above mentioned operation is trouble very, and is especially for measuring new hand, all the more so.

Summary of the invention: the purpose of this utility model just provides the quick centralizer of a kind of transit reasonable in design, easy and simple to handle.

The quick centralizer of a kind of transit, it is characterized in that: form by locating ring 1, centering pin 2, stator 3, anchoring filament 4, spacer pin 5 and the positioning pipe 6 that has a termination 7, centering pin 2 is crosswise and links on the inwall that is fixed on locating ring 1 with same state respectively, stator 3 is 120 degree and links respectively on the outside that is fixed on locating ring 1 with same state, and the positioning pipe 6 that has termination 7 is fixed on the stator 3 by anchoring filament 4 and spacer pin 5 bindings.

According to the quick centralizer of above-described a kind of transit, its feature also is: centering pin 2 is in the sustained height position of locating ring 1 inwall respectively, and stator 3 is in the sustained height position in locating ring 1 outside respectively.

Embodiment: in conjunction with the accompanying drawings, the implementation process of the quick centralizer of narration the utility model transit: the quick centralizer of the utility model transit is relatively simple for structure, locating ring 1 is a diameter height and the suitable tubular ring of thickness, is generally formed by the pipe system of cutting; Centering pin 2 is the suitably isosceles ladder type sheet material of (general identical with the thickness of locating ring 1) of a thickness, counts identical 4; Totally 3 of positioning pipes 6 are similar to telescopic receiving antenna on the radio, and just its binding stiff end (end that diameter is thicker) is flat and has two binding fixed orifices; Totally 3 of spacers 3 are the identical sheet material of material and thickness and centering pin 2, and this is identical mutually for the width base that width and positioning pipe 6 link stiff ends, and length is identical with the flat end of positioning pipe 6, and have two with positioning pipe 6 corresponding also identical binding fixed orifices.Centering pin 2 is crosswise and links respectively on the inwall that is fixed on locating ring 1, and its trapezoidal short end is pressed close to the center of circle of locating ring 1, and it is basic identical apart from the upper and lower distance of locating ring 1 to link stiff end; Three stators 3 are the sustained height position that 120 degree are separately fixed at locating ring 1 outside; Positioning pipe 6 is fixed on the stator 3 by anchoring filament 4 and spacer pin 5 bindings.

Embodiment: the intercepting diameter is that tubing one joint of 100mm, wall thickness 2mm, high 25mm is locating ring 1; The sheet material that the matter of drawing materials is identical, thickness is 2mm is processed into four high 45mm, upward the isosceles trapezoid of wide 2mm, following wide 5mm is a centering pin 2; The material of stator 3 is identical with the material of centering pin 2, is the strip of 25mm * 12mm, counts 3, the circular hole that to have two diameters above be 5mm; Positioning pipe 6 is made of three joints, the long 200mm of every joint, its flat one end with stator 3 bindings have with stator 3 on the corresponding binding fixed orifice of circular hole; The end with stator 3 bindings is not that a diameter is that 5mm, height are the columned termination 7 of 2mm.Centering pin 2 is crosswise links the middle part that is fixed on locating ring 1 inwall (be an end of centering pin 2 broads link with the upper and lower formula to be fixed on apart from locating ring 1 height two ends respectively be on the position of 10mm) respectively, the end that centering pin 2 is corresponding mutually (promptly not with the connecting end of locating ring 1) is at a distance of 10mm; To have two links fixedly the stator 3 of circular hole and is 120 and spends the middle part that level binding respectively is fixed on locating ring 1 outside; The flat of three telescopic positioning pipes 6 link binding fixed orifice on the corresponding respectively stator 3 of binding fixed orifice of stiff end be placed on stator 3 above, by anchoring filament 4 and spacer pin 5 positioning pipe 6 and spacer 3 bindings are fixed together.

Manipulate: after the upper shelf of measurement point has been propped up the tripod of transit and installed and fixed the upper warp and woof instrument, the quick centralizer of the utility model transit is placed under the tripod, allow the termination 7 of three positioning pipes 6 is corresponding to be pointed to the tripod of tripods and make the center of circle of locating ring 1 be in the top of measurement point, be the centre of measurement point in four centering pin 2 spaces, adjusting locating ring 1 with circular spirit-leveling instrument makes its upper end be in same horizontal level, draw back respectively three positioning pipes 6 make its termination 7 under the same length with after the same position of tripod tripod contacts, just can measure.
