Description
Technical field
The utility model relates to a kind of pitch tester, is specifically related to a kind of asphalt softening point proving installation.
Background technology
Softening point is one of three large technical indicators of asphalt material, has reflected the thermal stability of asphalt material.The test method of mensuration asphalt softening point commonly used is ball and ring method at present, ball and ring method is that the water that will be controlled at 5 ℃ is added in the cleansing bath tub, test piece mould and pitch sample are incubated at least 15 minutes under this water temperature, adopt electric heating coil that water is heated, make water temperature keep the speed of 0.5 ℃/min of 5 ℃ of scholars to heat up, the water temperature when the record steel ball drops into lower shoe.Once two groups of experiments are got the mean value of temperature as the softening point of this pitch.Water temperature is adjusted to 5 ℃ by testing crew in the method, then mould and pitch sample are incubated at least 15 minutes, but when summer high temperature is tested season, because heat, temperature is higher, water temperature raises very fast, water temperature can not be controlled at 5 ℃ and under this temperature, be incubated, so in this case, easily the test result of asphalt softening point caused larger error, and what at present softening point test was adopted is artificial reading, and operate miss also can cause test findings inaccurate, and measuring accuracy can not satisfy the demand that modern transportation is built.
The utility model content
The purpose of this utility model is to provide a kind of asphalt softening point proving installation, and described asphalt softening point proving installation kind work efficiency is high, be not subjected to such environmental effects, handling good.
For achieving the above object, the technical solution of the utility model is a kind of asphalt softening point proving installation of design, it is characterized in that comprise cleansing bath tub, the top of cleansing bath tub is provided with cover plate; Cover plate is fixed with the montant that is positioned at its below, is fixed with temperature sensor on the montant, and the montant bottom is fixed with the piezoelectricity tablet; Montant is fixed with the horizon sample plate between temperature sensor and piezoelectricity tablet, sample board is fixed with a plurality of horizontal set collars that run through up and down sample board, the interior fixedly pitch sample of set collar; Be fixed with sleeve pipe between set collar and piezoelectricity tablet, be provided with vertical Compress Spring in the sleeve pipe, the Compress Spring top is provided with push rod, and the compressed spring of push rod pushes against pitch sample lower surface; Be provided with well heater and refrigerator in the cleansing bath tub.
Preferably, described cleansing bath tub is enclosed with heat-insulation layer.
Preferably, described piezoelectricity tablet, temperature sensor, well heater and refrigerator are connected to respectively Programmable Logic Controller.
Preferably, described Programmable Logic Controller is connected with display device.
Mensuration process of the present utility model is as follows:
To boil the cool water of rear system joins in the cleansing bath tub, the pitch sample is placed in the set collar of sample board, generally is incubated at least 15 minutes, if the interior water temperature of cleansing bath tub is higher than 5 ℃ under the starting condition, according to the temperature data that temperature sensor detects, the Controlled by Programmable Controller refrigerator freezes; If water temperature is lower than 5 ℃ in the cleansing bath tub, according to the temperature data that temperature sensor detects, the Controlled by Programmable Controller well heater heats; When water temperature arrived 5 ℃, the power supply that Controlled by Programmable Controller is closed well heater, refrigerator was incubated; After temperature retention time arrived, the Controlled by Programmable Controller well heater heated, and made water temperature keep heating up with the speed of 0.5 ℃/min of 5 ℃ of scholars.During test, progressively softening when interior pitch sample, push rod passes the pitch sample fast under the promotion of Compress Spring, and piezoelectricity tablet upward pressure changes fast, this moment, Programmable Logic Controller was recorded the temperature data that temperature sensor detects, and drew the softening point of tested pitch.
The setting of a plurality of set collars and many parts of pitch samples can make the value of softening point of tested pitch more accurate.
Advantage of the present utility model and beneficial effect are: a kind of asphalt softening point proving installation is provided, and described asphalt softening point proving installation kind work efficiency is high, be not subjected to such environmental effects, handling good, has good practicality.
