Accompanying drawing explanation
Fig. 1 is the road surface construction degree of depth device for quick testing structural representation based on resistance response provided by the invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the road surface construction degree of depth device for quick testing based on resistance response provided by the invention is described in detail.
As shown in Figure 1, the road surface construction degree of depth device for quick testing based on resistance response provided by the invention comprises test barrel, counterweight 2, many thin plastic pipes 3, many springs 4, many probes 5, thin aluminum sheet 7, ammeter 9, power supply 10 and wires 11; Wherein test barrel is the drum-shaped structure surrounded by upper conductive plate 1, sidewall 6 and cylinder root edge 8; Sidewall 6 is made up of plastic board, because it is insulation materials, this makes it possible to ensure to only have probe 5 wherein to conduct electricity, and ensure that probe 5 is connected into the change of circuit part resistance to the reflection of experimental variable (the road surface construction degree of depth) further; Upper conductive plate 1 stamps multiple through hole, with fixing spring 4 by probe 5 arrangement; Counterweight 2 adopts sealing compound to be bonded on the external surface of conductive plate 1; The upper end of many thin plastic pipes 3 is fixed on the bottom surface of conductive plate 1 simultaneously, and with multiple through hole one_to_one corresponding; The inside of every root thin plastic pipe 3 arranges a spring 4, the effect of plastic pipe 3 limits the lateral displacement of the spring 4 arranged in it, each spring 4 is kept apart simultaneously, to ensure that each spring 4 can both work alone, reduce the friction between spring 4, be independent of each other, make it move up and down and move to be more prone to, the wire of every root spring 4 upper end is welded on conductive plate 1 external surface through after a through hole on upper conductive plate 1; Thin aluminum sheet 7 is horizontally set on test barrel inside, and exterior periphery is fixed on sidewall 6 inner surface; It acts on the brush that is equivalent in motor, and the every root probe 5 contacted with it can be made like this to link in circuit, thus can the change of resistance in actual response probe 5 place in circuit; The upper end of every root probe 5 is connected to the lower end of a spring 4, and thin aluminum sheet 7 and cylinder root edge 8 are run through in middle part, and bottom is positioned at below a root edge 8; The two ends of wire 11 are connected on conductive plate 1 and thin aluminum sheet 7; Ammeter 9 and power supply 10 are then connected in series on wire 11.Probe 5, spring 4, upper conductive plate 1, thin aluminum sheet 7, ammeter 9, power supply 10 and wire 11 form a closed-loop path, when this device is positioned over face, under the effect of counterweight 2, probe 5 will stretch with the concavo-convex change in face, road, thus the length making probe 5 connect in circuit changes, this change in length causes the generation current value change due to change in resistance in circuit, directly can be reflected the size of surface construction depth value of engaging in this profession by the change of instrumental calibration after-current value.
Described power supply 10 is dry cell, and voltage is 6V.
Described spring 4 is the nickel-copper wire helical spring that stiffness factor is less, and diameter is slightly less than the internal diameter of thin plastic pipe 3, and the quantity of spring 4 is 400-1000 root.
The dial plate of described ammeter 9 is marked with the road surface construction depth value corresponding with current value size.
Described probe 5 is made up of the stainless steel that rigidity is larger, and length is about 8cm, and the tip of Ф≤0.1mm worn into by tip emery wheel.
Described counter weight device 2 is the cylindrical structure be made up of rubber, and external diameter is identical with the internal diameter of sidewall 6.Because the elastic force that during test, spring 4 produces is unvanquishable by the deadweight of this device self, so must in addition counterweight, manually need not increase vertical force when testing so just can make probe 4 move up and down smoothly, and lower end enters in the groove in face.
Now the road surface construction degree of depth device for quick testing using method based on resistance response provided by the invention is described below: before use, need the dial plate of ammeter 9 to transform, method is the road surface construction degree of depth first testing out a certain FX with traditional paving micromicrofarad, experimental data is recorded again afterwards with this device to test, repeat to do lot of experiments, obtain the experimental data of being correlated with, and arranged, last Zai Jiang road surface construction depth value is marked on dial plate.
During test, by tester, probe 5 lower end on this device is placed on position to be tested, under the deadweight of counterweight 2 and device itself, device sinks, at this moment contact the probe 5 protruding position in face, road will move up, the spring 4 be connected with this probe 5 will be compressed, and all the other probes 5 enter into face groove.The resistance of the probe 5 at this moment in place in circuit changes along with the uneven of face, road, and embodies on ammeter 9.Tester obtains the road surface construction degree of depth at this test position place by the method reading registration on dial plate.In addition, can ammeter 9, power supply 10 and wire 11 be fixed on test barrel end face, only dial plate need be exposed, very practical and easy to carry.
