In the payingoff mechanism, the same prior art of other parts, wherein: have the wire coil shaft 11 of dialling arm and be installed on the frame 1, first transmission gear 8 of wire coil shaft 11 axle heads and second transmission gear, 16 meshing relations that are installed on the damping case output main shaft 19 by the bearing seat 15 that is fixed on the frame 1.Damping case 7 and frame 1 are for being fixedly connected.The output damping square of regulating damping case 7 just can change the rotary resistance of wire coil shaft 11, and drum 10 is to be fixed on the wire coil shaft 11 by hold-down nut 14, thereby the rotary resistance of change wire coil shaft 11 just can change the size of drum 10 laying tensions.
The principle of work of the utility model hydraulic efficiency pressure system is: referring to Fig. 6, during the beginning unwrapping wire, close the unloading valve 18 on the fuel priming pump 2, open tension adjustment hold-off valve 26, pressurize to hydraulic efficiency pressure system with fuel priming pump 2, annular piston 32 moves axially pressing friction sheet 24 to annular cylinder 31 outsides under the impetus of oil pressure, thereby produces frictional damping moment.Being pressurized to tensiometer 6 displayed values is to close the tension adjustment hold-off valve behind the desirable value.Can guarantee that damping moment is constant in two hours.The effect of energy storage is to store higher pressure when pressurizeing in the course of the work in advance, mild when guaranteeing to boost with tension adjustment hold-off valve 26 and continuing.
Brief description working process of the present utility model.
1. drum is installed and unwrapping wire:
Referring to Fig. 3, open the loam cake of bearing seat 15, take off hold-down nut 14 on the wire coil shaft 11, spacer 13, tapered sleeve 12 wire coil shaft 11 is inserted the centre hole of drums 10, adjust the bolt of dialling on the arm 9 and adorn the hole to correct position to dialling of drum 10; Put into tapered sleeve 12, spacer 13, hold-down nut 14, and jack panel 14 is pressed in dextrorotation; Wire coil shaft 11 and drum 10 liftings are gone into bearing seat 15; After being coated with moderate lubrication fat on bearing seat 15 endoporus and the spacing back-up ring, loam cake resets, screw cap nut, referring to Fig. 5, contact line conducting wire is pulled out from first pay off rack, 37 tops, by guidepost 38 (prior art) lead fixed in the contact system vertical rod, locomotive is at the uniform velocity advanced in the opposite direction, so lead is emitted.Second pay off rack, 36, the three pay off racks 35 are identical.
2. tension force setting:
Close the unloading valve 18 on the fuel priming pump 2, open the tension adjustment hold-off valve 26 on the damping case 7, the handgrip of moving on the fuel priming pump 2 gives annular cylinder 31 pressurizations with the hydraulic oil of 3 li of fuel tanks, and being pressurized to tensiometer 6 displayed values is to close tension adjustment hold-off valve 26 after the selected scope.This process should be done twice to confirm the accuracy of initial value.In the unwrapping wire process, damping case 7 can guarantee that damping moment is constant in two hours.
3. tension adjustment:
When tension force need increase, promote fuel priming pump 2 repeatedly, oil pressure is stored in the energy storage 4, after sensation promoted the resistance increase, the tension adjustment of coming up hold-off valve 26 increased to expected value and closes rapidly.When tension force need reduce, open unloading valve 18 on the fuel priming pump 2, the tension adjustment of coming up valve keeps 26, reduces to expected value and closes rapidly.
4. take-up:
After unwrapping wire finishes, regain as the line that need will be unnecessary, open tension adjustment hold-off valve 26 on the damping case 7 and the unloading valve 18 on the fuel priming pump 2, drum 10 gets final product hand-turning carry out take-up.
