Summary of the invention
The technical problems to be solved in the utility model is: for the problem existing in above-mentioned background technology, provide the accuracy test calibration device of portable plumb line coordinator a kind of easy to carry, simple to operate.
The technical scheme that the utility model technical solution problem adopts is: the accuracy test calibration device of portable plumb line coordinator, described test calibration device is arranged on the observation pier of described plumb line coordinator, described test calibration device comprises scaling ruler, the two ends of described scaling ruler are fastened on Magnetic gauge stand by connecting chi respectively, described Magnetic gauge stand is fixed on described observation pier, on described scaling ruler, there is the section of demarcation, the described section top, the vertical line hole that is positioned at described observation pier of demarcating, described demarcation section is provided with square groove, described square groove is being parallel to the length direction of described scaling ruler and is being provided with orthogonal calibrating block perpendicular to the length direction of described scaling ruler, the both sides of described calibrating block have index slot.
When adopting technique scheme, the utility model is further technical scheme below can also adopting or combine and adopting:
The two ends of described scaling ruler are respectively provided with 5 the first screw holes, one end of described connection chi is provided with the shape in described the first screw hole and arranges 5 all identical the second screw holes, between described scaling ruler and described connection chi, by screw is removable, is fixedly connected with.
The groove width of the index slot of described calibrating block both sides is identical, and the width sum of described calibrating block and described index slot is definite value.
The beneficial effects of the utility model are: the utility model has been designed dexterously and take the caliberating device that scaling ruler is core by simple structure, by the calibrating block and the index slot that arrange on scaling ruler, by calibrating block and index slot, limit the displacement of vertical line on scaling ruler, and the reading of this displacement and plumb line coordinator is contrasted, thereby the accuracy of evaluation plumb line coordinator reading.Advantage of the present utility model is mainly manifested in following two aspects: 1, simple operation, widely applicable.Test process of the present utility model saves loaded down with trivial details clamp process, with the line process that pushes away of calibrating block piece replace complex, fixing once can demarcate two vertical direction, and be applicable to a direction and be not easy to fixing situation; 2, easy to carry.Demarcation support body of the prior art is long-pending larger, and need to very wait accessory, and critical piece of the present utility model is all with the form of chi, and volume is little, and quality is light, and accessory is few, and assembly and disassembly are all very convenient.

Embodiment
With reference to accompanying drawing.
The accuracy test calibration device of portable plumb line coordinator of the present utility model is arranged on the observation pier 5 of plumb line coordinator, this test calibration device comprises scaling ruler 1, the two ends of scaling ruler 1 are fixed on Magnetic gauge stand 4 by connecting chi 2 respectively, Magnetic gauge stand 4 is fixed on observation pier 5, on scaling ruler 1, there is the section of demarcation 7, demarcate 6 tops, vertical line hole that section 7 is positioned at observation pier 5, demarcate section 7 and be provided with square groove 8, square groove 8 is provided with orthogonal calibrating block 1-1 being parallel on the length direction of scaling ruler 1 and the length direction perpendicular to scaling ruler 1, the both sides of calibrating block 1-1 have index slot 1-3.
The two ends of scaling ruler 1 are respectively provided with 5 the first screw hole 1-2, the one end that connects chi 2 is provided with the shape of the first screw hole 1-2 and arranges 5 all identical the second screw hole 2-1, between scaling ruler 1 and connection chi 2, by screw 9 is removable, be fixedly connected with, according to triangle stability principle, 3 screws 9 can fixedly secure scaling ruler 1 and be connected chi 2, 5 the first screw holes be set on scaling ruler 1 be no matter make scaling ruler 1 be in level, to fix or vertically can guarantee fixedly time the connection of 3 screws with being connected chi 2, a set of test calibration device should be furnished with a scaling ruler, two connect chi and six screws.
The length of scaling ruler 1 is 300mm, and width is 30mm, and thickness is 3mm, and the length that connects chi 1 is 300mm, and width is 30mm, and thickness is 3mm.The width of calibrating block 1-1 is 7.5mm, the groove width of the index slot 1-3 of calibrating block 1-1 both sides is identical, be 2.5mm, the width sum of calibrating block 1-1 and index slot 1-3 is definite value 10mm, when measuring, distance by vertical line from a sidesway of the index slot 1-3 of calibrating block 1-1 mono-side to the same side of the index slot 1-3 of opposite side is 10mm, and this is also for comparing the benchmark of plumb line coordinator reading.
In actual mechanical process, test calibration device of the present utility model can be installed according to the actual working environment of working-yard, if vertical line hole 6 is less, can use separately scaling ruler 1, if the aperture in vertical line hole 6 is larger, can parallel connection scaling ruler 1 be connected chi 2, this mounting means is as shown in Figure 5, under this mounting means, the first screw hole 1-2 at the two ends of scaling ruler 1 uses wherein outermost 3; If a side in vertical line hole 6 is not suitable for fixing, can adopt scaling ruler 1 and be connected chi 2 mode connected vertically, under this mounting means, scaling ruler 1 is 3 the first screw hole 1-2 of side with what be connected that chi 2 this one end connected vertically uses, as shown in Figure 6; The outer end that connects chi 2 all adopts Magnetic gauge stand 4 fixing.
Actual measurement process is as follows: first vertical line 3 is moved in the index slot 1-3 of calibrating block 1-1 mono-side, be adjacent to a wherein side channel wall, read the primary data of plumb line coordinator, then vertical line 3 is moved in the index slot 1-3 of calibrating block 1-1 opposite side, be adjacent to the same side cell wall, read the data for the second time of plumb line coordinator, according to the setting of scaling ruler 1, the displacement of vertical line 3 is width=10mm of width+index slot 1-3 of calibrating block 1-1, whether the difference of calculating twice reading of plumb line coordinator is 10mm, thus the accuracy of evaluation plumb line coordinator reading.
Owing to the utlity model has orthogonal two calibrating block and index slot, therefore only need one-step installation to demarcate both direction, easy to use.
