Description
Technical field
The utility model is related to plastic cement race track construction field, more particularly to a kind of to be used for detection paving property plastic cement race track surface layer
The detection ruler of thickness.
Background technology
The form of construction work of current plastic cement race track, is typically first to pour on the ground after smooth concrete surface layer, then the plastic cement that paves
Runway.Conventional property plastic cement race track surface thickness detection, using sampling method, takes some cylindrical sample prescriptions on plastic cement race track,
The thickness of some sample prescriptions is measured again, is averaged.
Because pendulous frequency is more, the average of obtained runway thickness is more accurate.But, race is but destroyed while measurement
The structure in road, in order to avoid influenceing the service life of runway because of measurement, so can not carry out more frequently taking a measurement.
Utility model content
The purpose of this utility model is to provide a kind of detection ruler for detecting paving property plastic cement race track surface thickness, in measurement
During runway cover thickness, survivable track elements can carry out more taking a measurement, the runway cover thickness measured is more smart
Really.
Above-mentioned purpose of the present utility model technical scheme is that：One kind paving property of detection plastic cement is run
The detection ruler of road surface thickness, including detection device and reading plotter, detection device include feeler lever, are fixedly arranged on the spy of feeler lever bottom
Pin, and the heater heated for probe, reading plotter are slidably connected on feeler lever, and are pierced into plastic cement race track face with probe
Along feeler lever equal length displacement occurs for layer, reading plotter.
By using above-mentioned skill scheme, the fusing point of plastic cement race track is told somebody what one's real intentions are, heated generally between 150 DEG C~200 DEG C
Probe temperature can reach more than 500 DEG C, so as to be easily inserted into plastic cement race track surface layer.In the same of insertion plastic cement race track
When melt plastic cement race track, plastic cement race track generally paves on concrete soil layer, and the probe of heating, which runs into concrete soil layer, can not continue downwards
Be pierced into, between reading plotter and feeler lever the size of relative displacement with this plastic cement race track surface thickness it is equal in magnitude.Then to
Upper taking-up probe, loses the heating of probe, and plastic cement race track can be solidified rapidly again, and breach is left without original place again so that
Survivable track elements during measurement, and the measurement of more points can be carried out so that the result that measurement is obtained is more accurate.
Further, reading plotter includes the graduated scale and sliding component being fixed on feeler lever, and sliding component is slidably connected at quarter
The scale on chi and on indicating graduation chi is spent, its bottom is in same level with probe bottom during sliding component nulling.
By using above-mentioned technical proposal, when probe is pierced into plastic cement race track surface layer, depth size and cunning that probe is pierced into
Move the skidding distance of part on the scale equal in magnitude, and due to the initial position nulling of sliding component, so what sliding component was indicated
Scale, is both pierced into the thickness of plastic cement race track surface layer for probe.During measurement when probe touches plastic cement race track just, the bottom of vernier
End also touches plastic cement race track just, continues to be pierced into probe into plastic cement race track, during probe is constantly inserted, vernier bottom
End is contradicted on plastic cement race track surface, so that vernier is slided along graduated scale, so as to obtain representing the reading of probe insertion depth.
Further, heater includes insulating heat-conductive rod and the heating resistance wire being wrapped on insulating heat-conductive rod, insulation
Heat conductive rod is connected with probe.
By using above-mentioned technical proposal, heat is passed to hot pin using heating resistance wire heating power, and by insulation
Pass probe.Add the use safe coefficient of this programme.
Further, in addition to support body, support body is provided with reel, and suspension line one ends wound is on reel, the other end
Feeler lever is hung up.
By using above-mentioned technical proposal, by controlling reel to control the folding and unfolding of suspension line, so as to control probe vertical
Piercing plastic cement race track.
Further, being provided with the top of feeler lever is used to promote the elongation mechanism that feeler lever is moved downward, and elongation mechanism top is provided with
Limit assembly, limit assembly is slidably connected on support body, and stops that elongation mechanism is protruded upward.
By using above-mentioned technical proposal, handwheel control suspension line unwrapping wire is rotated first so that the spy in suspension status
Bar can be moved vertically downwards, so that the piercing plastic cement race track of probe straight.Then elongation mechanism is driven, in limit
Elongation mechanism promotes feeler lever to continue to move downward under the stop of hyte part so that the insertion plastic cement race track surface layer that probe can be straight
Bottom.
Further, elongation mechanism includes the inflator inside the internal bellows provided with confined space and diaphragm for passageway,
Bellows top and limit assembly are inconsistent, and bottom is fixed on feeler lever top.
By using above-mentioned technical proposal, inflated using inflator into bellows so that the air pressure in bellows increases, from
And bellows is propped up into elongation, limited because bellows top is limited component, so bellows can only be vertically downwards
Elongation is so as to promote probe to continue into plastic cement race track deeply.
Further, bellows top is extended with least two guide rods vertically downwards, and feeler lever is provided with for leading
The sliding sleeve slided to bar, guide rod is parallel to feeler lever.
By using above-mentioned technical proposal, guide rod can only in the vertical direction slided in sliding sleeve, so bellows with
Vertically extend.
Further, limit assembly includes being used for stopping depression bar that elongation mechanism vertically protrudes upward and for solid
The tightening piece of level pressure bar, support body is provided with the chute that voltage supply bar is slided, and depression bar is detachably secured in chute by tightening piece.
By using above-mentioned technical proposal, the height of depression bar can be adjusted by being slided in chute, in regulation to conjunction
Depression bar is fixed with tightening piece during suitable height.
In summary, the utility model has following beneficial effect：
1st, this programme, using the low-melting feature of plastic cement race track, heats plastic cement race track in measurement when taking measurement
Melt, plastic cement race track solidifies recovery automatically after measurement, and the destruction to plastic cement race track is smaller.So as to carry out large area, big model
That encloses more takes a measurement, so as to obtain more accurate measurement result.
2nd, the insertion plastic cement race track surface layer of probe straight is promoted using the cooperation of elongation mechanism and limit assembly, it is to avoid
People's manual operations forms larger error, makes measurement result more accurate.
