Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further。
As Figure 1-3, including test screw 1, circular wired 2, upper bracket 3, cover plate 4, gear train 5, bearing block 6, briquetting 7, base plate 8, driven shaft 9, adjusting bolt 10, adjusting nut 11, pulley 12, spring 13, detection steel wire 14, fastening screw 15, through wires hole 16, hollow out projected area 17, hang code fixing point 18, lower carriage 19 and bar shaped wired 20。
The machinery of wavelength is surveyed under loading force, including upper bracket 3, bearing block 6, base plate 8 and lower carriage 19, one end of base plate 8 is connected with one end of lower carriage 19, the other end of lower carriage 19 is provided with pulley 12, base plate 8 is provided with two bearing blocks 6, the base plate 8 between two bearing blocks 6 is provided with hollow out projected area 17;Being equipped with upper bracket 3 on each bearing block 6, upper bracket 3 and lower carriage 19 be arranged in parallel, and after cooperation, upper bracket 3 is arranged on the phase of two bearing blocks 6 laterally。Two upper brackets 3 are symmetrical arranged two pairs of test screws 1, be provided with on a pair of bearing block 6 test screw 1 with the use of circle wired 2 and spring 13, it is connected with bar shaped wired 20 at a pair test screw 1 away from bearing block 6, and the test screw 1 away from bearing block 6 is suspension code fixing point 18。
Circle wired 2 and spring 13 are used for clamping detection steel wire 14, detection steel wire 14 is fixed by the circle wired 2 testing screw 1 of close bearing block 6 and spring 13 after through wires hole 16, detection steel wire 14 encloses around one on circular wired 2, then again not in bar shaped wired 20, in order to share stress when detection steel wire 14 clamps, in case breaking。
Near lower carriage 19 upper bracket 3 on be provided with the use of adjusting bolt 10 and adjusting nut 11, adjusting nut 11 is directly anchored in adjusting bolt 10, in one end of adjusting bolt 10 equipped with the axis of guide, at the oilless bearing used equipped with the cooperation axis of guide on the upper bracket 3 of lower carriage 19 so that adjusting bolt can horizontally slip on the axis of guide。
Being equipped with gear train 5 on each upper bracket 3, gear train 5 includes a drivewheel and a driven pulley, and the driven gear on two upper brackets 3 is connected by driven shaft 9, is equipped with through wires hole 16 at drivewheel center。
Base plate 8 is connected with lower carriage 19 by fastening screw 15, and bearing block 6 is connected with base plate 8 by fastening screw 15。Being provided with a pair briquetting 7 on base plate 8, briquetting 7 is fixed by fastening screw 15, is used for the gap adjusting between two gear trains 5。Test screw 1 screws for plug, and fastening screw 15 is hexagon socket head cap screw。
Work process: the scale being separately fixed at detection steel wire 14 two ends in the loading force detection circle wired 2 at frock two ends and bar shaped wired 20 under profile projector according to device one end constantly rotates steel wire and adjusts measurement angle;By carrying additionally counterweight in pulley 12 one end to detection steel wire 14 loading tensile;By adjusting nut 11 outward turning, bouncing back in case detecting steel wire 14 after removing loading force, detecting device can be placed on projector and detecting wavelength wave height and loading force elongation。
Helix loading force detection example: loading force is detected frock and keeps flat on the table。Take the spiral steel wire (detection steel wire 14) of 600mm length, by spiral steel wire through through wires hole 16, spiral steel wire two is fixed with wired respectively。By in the one end having pulley, hang counterweight to spiral steel wire loading tensile for fixing point pulley for towing point hanging code fixing point 18。Due to pulling force effect, support 3 will be displaced outwardly, and at this moment rotatable adjusting nut is to be adjacent to support 3。After reaching the regulation loading tensile time, counterweight (external force) is removed, be elongation with the end face distance of kind of calliper adjusting bolt Yu adjusting nut。Finally whole device is placed under profile projector, the wavelength wave height of spiral steel wire can be observed through the vacancy section on base plate, and synchronous rotation device can be passed through, it may be achieved and when spiral steel wire entirety relative position is constant, the wavelength wave height of arbitrarily angled observation spiral steel wire。
