Description
The utility model relates to a kind of testing tool of asphalt performance index, relates in particular to the bitumen extender of measuring pitch extension value, is applicable to the ductility of materials such as measuring road asphalt, eu-bitumen bottoms and Asphalt Emulsion Evaporation Residue.
The tension test of pitch need be immersed the pitch die trial in the water, and control water temperature is constant, at the uniform velocity is stretched to pitch die trial fracture and promptly obtains its ductility value.Generally speaking, draw speed is 5cm/min when water temperature is 25 ℃, and draw speed was 1cm/min when water temperature was 15 ℃.Draw speed is quite slow, and this need carry out speed change with rotating speed of motor, and the speed during different temperatures also needs to switch.Stretching, it is little to need steadily, vibrate.At present, the stretching mode of the bitumen extender of being produced is the leading screw mode, just realizes draw speed with speed reduction unit and leading screw, because leading screw pitch and profile of tooth have error, causes draw speed inhomogeneous like this, and bigger vibration is arranged.After the pitch die trial is stretched to certain-length, can become very thin and hairline similar, if, can make its fracture, cause tensile elongation to shorten at this moment because vibration or speed are inhomogeneous, inaccurate to estimating asphalt performance, this is that the performance of instrument own is good and cause.Given this plant situation, abroad some advanced countries realize that with leading screw and speed reduction unit draw speed changes the wire-pulling type structure into.With the wire-pulling type pitch that stretches, realize the draw speed uniform and stable, vibrate for a short time, such as the bitumen ductility instrument that Sweden produces, adopt volute spring return mode, by the big energy of spring (disc spring) distortion storage; Delivered energy during return; The designing and calculating of this spring is complicated, even designing and calculating is very accurate, also need produces, manufacture experimently through special manufacturer, and manufacturing cost is higher.
The purpose of this utility model provide a kind of draw speed evenly, stable working, simple in structure and easy to operate bitumen extender.
The purpose of this utility model is achieved in that
It comprises switch board, water-bath, speed reduction unit, be characterized in: it also comprises frequency converter and by fixing supporting plate, mobile pallet, backguy, the fixed pulley closed loop that the fixed pulley group is formed is toward multiple line machine drawing structure, the arranged outside switch board of water-bath, the inner chamber left end of water-bath is fixed with fixedly supporting plate, mobile pallet is arranged at fixedly the right of supporting plate, the fixed pulley group is made up of a plurality of fixed pulleys and is installed on the casing of water-bath right-hand member, one of them fixed pulley is fixed on fixedly on the supporting plate, speed reduction unit is positioned at the top of fixed pulley group, one end and the mobile pallet of backguy are affixed, after roll through walking around speed reduction unit and the fixed pulley group, the other end is fixed on the mobile pallet.
By the switch board starting switch, make frequency converter and speed reduction unit work, backguy speed on request on the roll of speed reduction unit moves mobile pallet, being fixed on fixedly, the pitch die trial between the supporting plate and mobile pallet is stretched, draw speed evenly, steadily, satisfy test request, make the mobile pallet return by the counter-rotating of speed reduction unit motor, it is extremely convenient to operate.
Compared with prior art, the fixed pulley closed loop that the utility model adopts is toward multiple line machine drawing structure, and is simple in structure, cost is low, not only stable working, friction, and also draw speed is accurate, and easy to operate.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the bitumen extender synoptic diagram.
It comprises switch board 1, water-bath 2, speed reduction unit 7, frequency converter 8 and the fixed pulley closed loop formed by fixedly supporting plate 3, mobile pallet 4, backguy 5, fixed pulley group 6 toward multiple line machine drawing structure.
According to technique scheme, switch board 1 and water-bath 2 are fixedly connected into the console mode one-piece construction, profile is a rectangular parallelepiped high-low cabinet form, the stainless steel manufacturing is adopted in water-bath 2.Electrical control cubicles 1 and stainless steel water-bath 2 have temperature automatically controlled function, such as heating automatically or refrigeration; Automatically as water and water cycle function.The inner chamber left end fixed installation of water-bath 2 is supporting plate 3 fixedly, and the right and the along continuous straight runs of supporting plate 3 move but mobile pallet 4 is arranged at fixedly.Fixed pulley group 6 has three fixed pulleys, two fixed pulleys wherein are fixedly mounted on the casing of water-bath 2 right-hand members, another fixed pulley is fixed on fixedly on the supporting plate 3, and speed reduction unit 7 is positioned at the top of two fixed pulleys and is fixedly mounted on the casing, and backguy 5 is made up of multiply stainless steel steel wire.The initiating terminal of backguy 5 is fixedlyed connected with mobile pallet 4, backguy is pulled to right-hand member pass on the casing that is installed in water-bath 2 right-hand members a fixed pulley in two fixed pulleys, then 8～10 circles on the roll of speed reduction unit 7, pass another fixed pulley then, again backguy is pulled to the left side, pass the fixed pulley that is fixed on the fixing supporting plate 3, the not end of backguy 5 is fixed on the mobile pallet (4), form the fixed pulley closed loop toward multiple line machine drawing structure.Adopt fixed pulley to reduce friction, prolong the serviceable life of steel wire backguy, backguy 5 around 8～10 circles, effectively increases friction on the roll on the speed reduction unit 7, makes and is unlikely the generation wriggling when stretching, skids, and it is inhomogeneous to prevent to produce draw speed.
Principle of work of the present utility model is such: the pitch die trial is fixed on fixedly between the supporting plate 3 and mobile pallet 4, by switch board 1 starting switch, make frequency converter 8 and speed reduction unit 7 work, be transferred to the frequency of setting when frequency converter 8, again by speed reduction unit 7, backguy 5 speed on request on the roll of speed reduction unit 7 is stretched, and mobile pallet 4 moves under backguy 5 pulling force effects, and the pitch die trial is stretched, reverse by speed reduction unit 7 motors, make mobile pallet 4 returning quicklies, adopt the fixed pulley closed loop toward multiple line machine drawing structure, draw speed can be realized 1cm/min and 5cm/min, satisfy test request, the pitch die trial in the process that is stretched, stable working not only, friction, and draw speed is accurate, the fixed pulley closed loop is rapid toward multiple line machine drawing structure return, and it is extremely convenient to operate, simultaneously, compared with prior art, the utility model also has simple in structure, makes low cost and other advantages easily.
