On trapezoid support 11, be provided with support 3, the lower end of support 3 is welded on trapezoid support 11, and the upper end face of support 3 is provided with axis hole, screw and charging aperture.Agitator 2 is fixed in support 3, the first flowline 5 of agitator 2 lower ends is fixed on together with the corresponding fuel feed hole that end face on inverted trapezoidal charging box 6 is provided with, insert in agitator 2 with the axis hole of motor shaft end face from support 3 of stirring vane, on bolt, on support 3, in the screw of end face, motor is fixed on the end face of support 3.On the first flowline 5 of agitator 2 lower ends, the first switch 12 or valve is installed.
The method for filling of a kind of non-fragment orbit of the present invention shrinkage joint caulk compound, is characterized in that: comprise the steps:
(1) the caulk compound base polyurethane prepolymer for use as component (A) and the curing compound component (B) that extracted by weight 1: 3 are poured in agitator, and make the stirring vane liquid that all submerges;
(2) start motor, drive stirring vane to stir, empty load of motor rotating speed is controlled at 500-1500r/min, mixing time 2-3min;
(3) open first switch (blade-shaped switch) at agitator discharge port place, the caulk compound being stirred is flow to charging box by agitator bottom discharge mouth, leave standstill 1min;
(4) turn on grease gun top cover and stretch into charging box discharge port on backward, pull pull bar to make grease gun piston shift backward grease gun rear end cap onto, and grease gun rear end cap is seated on base 10, the grease gun body of a gun is installed in snap ring, and pull bar is installed on that draw-in groove 13 on base 10 is interior fixes grease gun;
(5) filling butter, opens the second switch (blade-shaped switch) at charging box discharge port place and controls discharging, can once pour into 1-10 and prop up grease gun, and no discharging switch cuts out;
(6) unload after the complete grease gun of perfusion, by the top cover with oil fuel tube to grease gun and tighten top cover;
(7) oil fuel tube on grease gun is extend in shrinkage joint, promote pull bar piston operation is pushed the butter in grease gun body, in 5-10 minute, slowly butter extruding is noted in shrinkage joint.
The invention has the beneficial effects as follows: the method for filling of a kind of non-fragment orbit shrinkage joint caulk compound, in the time carrying out the perfusion of non-fragment orbit shrinkage joint, by stirring, leave standstill, packing three road working procedures merge into after one working procedure, butter is injected in the filleting of non-fragment orbit shrinkage joint with grease gun.Saved cost, overcome traditional method for filling waste, avoided pollution road bed board, accelerated the speed of application of perfusion butter, improved the pouring quality of caulk compound, produced good economic benefit and social benefit.
