Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in figures 1-8.
A kind of integrated form bituminous epoxy low temperature load deformation temperature determines device, and it includes refrigeration machine 1 and experiment casing 2,
As shown in figure 1, refrigeration machine 1 can use conventional refrigeration device, bath 3 is installed in experiment casing 2, such as Fig. 2, the top of bath 3
If upper liquid pipe 15, bottom is connected with discharging tube 16 so as to the liquid of the discharge submergence sample for adding, and refrigeration machine 1 is connected by freezing
Pipe and the refrigerator pipes being arranged in bath 3（Spirality copper tube can be used）It is connected so as to freezing inside bath 3, freeze
Connecting tube should take Insulation；The temperature in bath 3 is adjusted when heater 4 is also equipped with inside bath 3 to test, in order to
Make temperature Quick uniform in bath, should also install electric stirring axle 12 additional in bath, agitating shaft 12 drives stirring vane thereon
Rotate, as shown in Fig. 5,6,7；Panel 5 that is can lifting and being sealed to it is installed, panel 5 is by both sides electricity on bath 3
Dynamic push rod 10 is realized moving up and down, so as to open or close bath 3, during electric pushrod 10 is arranged on experiment casing 2, bath 3
Outside, such as Fig. 8.Described panel 5 can be constituted by upper and lower two pieces（Such as Fig. 5）, the panel of bottom is used to be tightly connected with bath, under
The panel in portion is used to install pallet and sets electric switch button.Pallet 6 is installed, in pallet 6 and insertion bath 3 on panel 5
Load beam 7 be connected, the top of load beam 7 is sleeved in the fairlead 17 being fixed on panel 5.Load beam 7 be connected with directly with
The pressure head 14 of sample contacts, the end of pressure head 14 is hemisphere face structure, such as Fig. 6, the lower end of load beam 7 be lifted under panel 5
The specimen mounting 8 in portion is relative, and specimen mounting 8 is provided with for placing sample and being conducive to raised 9 for deforming.In the side of experiment casing 1
Amesdial bar 11 is installed, indicator and the weights being placed in pallet 6 of the amesdial on amesdial bar offset；In face
Angle mount is inserted on plate 5 thermometric galvanic couple 13（Fig. 4）.The test stand 8 of more than four can be installed in same bath, i.e., during specific implementation
The test of the sample of more than four can simultaneously be carried out.
Workflow of the present utility model is：
First the liquid of certain volume should be injected before experiment in experiment bath 3（Alcohol）, from the rear filler injection of bath.
By the electronic lifting of specimen mounting 8, the stainless steel that the test sample bar of selection is placed between specimen mounting two-way frame is hung as needed
In basket, and whole surface is covered with stainless steel substrates, but be not pressed onto the upper surface of testing bar, its surface is kept smooth shape
State is to starting deformation test.
Sample is installed after placement finishes, and is drop to specimen mounting 8 is electronic in bath 3, in experimental rig front panel touch-control
Test parameters is set in screen, starts refrigeration control key, central processing unit（The equipment is based on ARM and controls research and development）, sent out to refrigeration machine
Work order is sent, compressor operating, refrigeration machine is connected with the condenser inside bath, now channel interior refrigerant is played and made
With bath internal liquid is progressively cooled to -40 DEG C.
After test parameters is set, while refrigeration machine works, stirring button is opened, now stirring motor drives two rapid pulses
Line and the flabellum being connected with rapid pulse line are rotated, and internal liquid is stirred, so that the internal liquid more preferable temperature of acquisition is equal
Even property, allows temperature in the bath that four temperature measuring points measure to be held at -40 DEG C.
Specimen mounting is risen after spending a few minutes, reserves a small amount of operable space, by the stainless steel substrates on testing bar top
Remove out, while testing bar is quickly transferred on the raised two ends of span with tweezers（This process gives tacit consent to testing bar in low temperature
Lower removal stainless steel substrates, to be transferred to specimen mounting projection during there is no any deformation）, then load beam bottom is put
Put on testing bar, positional deviation occurs in bath to prevent testing bar, start decline button immediately after, by specimen mounting 8
Fall in the lump with panel 5, while the temperature in bath is carried out a refrigeration cool-down again, -40 DEG C of the minimum temperature for extremely setting, when
Four temperature measuring points detect temperature after -40 DEG C, then are kept for a few minutes, and preparation proceeds by determining displacement.
Load beam pressure head is placed on the upper surface end of testing bar simultaneously, after pressure head is installed in load beam bottom, correspondence is chosen
The counterweight of pressure is positioned in upper tray 6, and the amesdial bottom on table bar is placed on counterweight, end active segment compression one
After positioning is moved, amesdial resets, and system judges to be now zero point.
By bath internal liquid temperature refrigeration to after setting -40 DEG C of temperature, treatment gathers the temperature spot to refrigeration machine（In bath
Portion is equipped with five PT100）, judge that temperature reaches experimental condition, the instruction that is stopped is sent, refrigeration machine is stopped.
After refrigeration machine is stopped, processor automatic running program starts the heater inside bath, and crawl heating is real
Shi Jilu and judge heating rate, speed is corrected automatically.
Under the heating rate and load of regulation, when sample deformation amount reaches required, the amesdial on counterweight top is produced
Raw identical displacement, processor reads amesdial displacement, and record reaches deformation temperature during regulation offset variable, and correspondence is each
Individual station does identical logical action.
When the experiment of all stations reaches requirement, system autostop, alarm, test temperature is recorded in storage inside.
Experimental provision rear portion has communication interface, can simultaneously access computer, synchronous recording process of the test temperature and curve.Off-test
Afterwards, internal liquid is released into sealed storage.Experimental rig rear portion stop valve is opened, the valve is closed after liquid is drained（Bath tub bottom part
Service valve is installed in portion, and the valve is opened for a long time）.
The utility model is not directed to partly same as the prior art or can be realized using prior art.
