Accompanying drawing explanation
The road surface construction degree of depth device for quick testing structure based on resistance response that Fig. 1 provides for the present invention
Schematic diagram.
Detailed description of the invention
Face, the road structure based on resistance response with specific embodiment, the present invention provided below in conjunction with the accompanying drawings
Make degree of depth device for quick testing to be described in detail.
As it is shown in figure 1, the road surface construction degree of depth based on resistance response that the present invention provides quickly tests dress
Put and include test barrel, counterweight 2, many thin plastic pipes 3, many springs 4, many probes 5, thin aluminum sheets
7, ammeter 9, power supply 10 and wire 11；Wherein test barrel is by upper conductive plate 1, sidewall 6 and cylinder
The drum-shaped structure that root edge 8 surrounds；Sidewall 6 is made up of plastic board, owing to it is insulant, this
Sample is to ensure that probe 5 the most therein is electrically conductive, ensure that probe 5 is connected into circuit further
The change of the part resistance reflection to experimental variable (the road surface construction degree of depth)；Probe is pressed on upper conductive plate 1
5 arrangements stamp multiple through hole, with fixing spring 4；Counterweight 2 uses insulating cement to be bonded in conduction
On the outer surface of plate 1；The upper end of many thin plastic pipes 3 is also secured on the bottom surface of conductive plate 1,
And with multiple through hole one_to_one corresponding；The inside of every thin plastic pipe 3 arranges a spring 4, plastic tube 3
Effect on limit the lateral displacement of the spring 4 arranged in it, each spring 4 is kept apart simultaneously, with
Ensure that each spring 4 can work alone, reduce the friction between spring 4, be independent of each other so that it is
Can only move up and down and move and be more prone to, the tinsel of every spring 4 upper end passes on upper conductive plate 1
A through hole after be welded on conductive plate 1 outer surface；Thin aluminum sheet 7 is horizontally set on inside test barrel,
And exterior periphery is fixed on sidewall 6 inner surface；It functions as the brush in motor, so may be used
Make every probe 5 in contact can link in circuit such that it is able to actual response probe 5 accesses
The change of resistance in circuit；The upper end of every probe 5 is connected to the lower end of a spring 4, middle part
Running through thin aluminum sheet 7 and cylinder root edge 8, bottom is positioned at below a root edge 8；The two ends of wire 11 connect respectively
On upper 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
One closed-loop path, when this device is positioned over face, under the effect of counterweight 2, probe 5 will be with
The concavo-convex change in face, road and stretch so that the length that probe 5 is connected in circuit changes, this length
Change causes producing current value change in circuit due to change in resistance, is become by instrumental calibration after current value
Change can directly reflect the size of surface construction depth value of engaging in this profession.
Described power supply 10 is aneroid battery, 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 thin plastic pipe
The internal diameter of 3, 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 rustless steel that rigidity is bigger, a length of about 8cm, tip emery wheel
Wear into the tip of Ф≤0.1mm.
The cylindrical structure that described counter weight device 2 is made up of rubber, and external diameter and sidewall 6
Internal diameter is identical.Because the elastic force that during test, spring 4 produces is unvanquishable by the deadweight of this device self,
So must in addition counterweight, so need not manually increase during test vertical force just can make probe 4 smooth on
Lower movement, and lower end enters in the groove in face.
The road surface construction degree of depth device for quick testing user based on resistance the response now present invention provided
Method is described below: need the dial plate by ammeter 9 to transform before use, and method is first with traditional paving
Micromicrofarad tests out the road surface construction degree of depth of a certain fixed area, the most again with this device to test and record examination
Test data, repeat to do lot of experiments, obtain the test data being correlated with, and arranged, last Zai Jiang road
Surface construction depth value is marked on dial plate.
During test, 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, and at this moment contacts the probe protruding position in face, road
5 will move up, and the spring 4 being connected with this probe 5 will be compressed, and remaining probe 5 then enters into
In the groove of face.At this moment the resistance accessing the probe 5 in circuit will become along with the uneven of face, road
Change, and embody on ammeter 9.Tester can obtain by reading the method for registration on dial plate
The road surface construction degree of depth at this test position.It addition, can be by solid to ammeter 9, power supply 10 and wire 11
It is scheduled on test barrel end face, only dial plate need to be exposed, very useful and easy to carry.
