Fig. 1 is a structural representation of the present invention; Fig. 2 is the lateral plan of Fig. 1; Fig. 3 is the birds-eye view of Fig. 1; Fig. 4 is the tension measuring device structural representation.
The specific embodiment
Among Fig. 1, present embodiment overlaps independently by two that tension force applies and measuring mechanism is formed.Bracing frame 2 is used to install that tension force applies and each parts of measuring mechanism, parallel on the bracing frame 2 two pivot shafts 10 is installed
-1, 10
- 2, second pivot shaft 10
-2On two concentric second friction wheels 6 are installed
-2 First pivot shaft 10
-1On two first concentric friction wheels 6 are installed
-1, and at first friction wheel 6
-1The outside a concentric free gear 5 respectively is installed; Two friction wheels 6 of the same side on two pivot shafts
-1, 6
-2The friction pair that partners is formed two pairs of separate friction pairs altogether.Bracing frame 2 is provided with two cover actuating devices 8, respectively by its driving gear and wherein two a ring gears engagement of overlapping on the friction pair, can drive the friction pair rotation, and friction pair amplifies the tension force that twines clue thereon by static friction force, and two clues of being put simultaneously for constant-tension stringing vehicle provide laying tension respectively.1 is protective cover, is used to protect the gear ring of actuating device 8 and friction wheel 6.(being two friction wheels, the 6 positive centre bottom of bracing frame 2 homonymies) has tension measuring device 3 at positive center, every pair of friction pair bottom, and promptly tension measuring device 3 is installed in second friction wheel 6
-2And on 2 bases of the bracing frame between the free gear 5, second friction wheel 6 that the roller groove of its roller set and free gear wire casing, clue are left at last
-2Wire casing is in the same vertical plane surface; Each roller of roller set is positioned at second friction wheel 6
-2On the circumference of the circumcircle of free gear 5 (among the figure shown in the dotted line), so the vertical component of clue is born simultaneously by several rollers, single roller stressed little can not caused damage to the clue surface.Clue 9 is passed and is walked around free gear 5 behind the roller of tension measuring device 3 again and leave this mechanism and carry out unwrapping wire, the tension measuring device installation site is lower, with the tensile stress of induction clue 9 vertical direction component, obtain the actual tension value of clue 9 indirectly by the component of measuring the clue vertical direction.4 is cord grip.
Among Fig. 2, actuating device 8 is a hydraulic drive mechanism, mainly comprises hydraulic drive motor, reductor, drg, driving gear etc.Reductor is installed on the bracing frame, and gear is connected by flat key with reductor.Actuating device 8 is used to provide the power of tension mechanism.Friction wheel 6 comprises compositions such as friction lining, friction disc, gear ring, bearing, axle and axle sleeve, friction disc is installed on the pivot shaft 10 of bracing frame by parts such as bearing, axle sleeve and axles, power is obtained in driving gear engagement by gear ring and actuating device, friction lining is installed on the outer ring of friction wheel, which is provided with wire casing 11, make by high coefficient of friction material.Friction wheel 6 is used for the actuating device moment of torsion is delivered to the clue on wire casing 11 surfaces, and the tension force in the clue is amplified.5 is free gear.3 is tension measuring device.
Among Fig. 3, the bracing frame two ends are provided with cord grip 4.Cord grip 4 comprises parts such as support, fabric wheel, handwheel, screw rod, axis pin of the spring, and cord grip can promote fabric wheel motion by handwheel and screw rod clue tightly is pressed on the wire casing, prevents that clue from taking off groove from wire casing.Free gear 5 is installed in first friction wheel 6
-1The outside, its diameter is identical with friction wheel, is made up of liner, rolling disk, bearing and axle sleeve etc., and effect is itself and first friction wheel 6
-1Separate, and can be at first pivot shaft 10
-1Go up with first pivot shaft 10
-1For rotating freely, the center do not have rotary resistance (rotary resistance is minimum ignores), the tension force equivalent of emitting clue is delivered in the tension measuring device undampedly, makes the detected thread tension force value of tension measuring device can accurately reflect the actual tension of clue.Two pivot shafts 10
-1, 10
-2Two friction wheels 6 of last the same side
-1, 6
-2Friction pair partners.Be provided with retaining line apparatus 7 between friction wheel 6, free gear 5 and the bracing frame, retaining line apparatus 7 is loaded on the bracing frame two ends, and because of after the abnormal condition clue takes off groove, retaining line apparatus 7 can protect clue not snap in damage wires in the space between bracing frame and each parts.
Among Fig. 4, tension measuring device is installed on the bracing frame, its roller set 12 by several hardness ratio clues low slightly and roller that the abrasion resistant material forms form, be installed on the roller mount 13; Roller mount 13 is articulated in leverage 16 ends; Pulling force sensor 14 is used to respond to the vertical tension of clue, and its two ends are equipped with connecting rod free to rotate 15, and connecting rod 15 tops and leverage 16 are hinged, and connecting rod 15 bottoms and base 18 are hinged, and assurance sensor 14 is not subjected to shearing stress and damages; Leverage 16 is hinged with base 18.Leverage 16 is used for that the vertical tension that roller set 12 is responded to is delivered to sensor 14 to be measured, and increases the measurement range and the sensitivity of sensor 14.17 is protective cover, can protect sensor 14 not to be subjected to the erosion of dust, rainwater.
During operation of the present invention, clue is pulled out the back from second friction wheel 6 by pay off rack
-2Enter, be wrapped on two friction wheels 6, can twine five circles at most; Cord grip 4 tightly is pressed in clue 9 on the wire casing 11, prevents clue 9 slippage from wire casing 11; Actuating device 8 is by 6 motions of gear drive friction wheel, and friction wheel rotation trend is opposite with the sense of motion of clue during the unwrapping wire operation.Because the effect of friction force makes the thread tension force that is wrapped on the friction wheel 6 be amplified to requirements; Clue 9 is from second friction wheel 6
-2Come out after the roller set 12 freedoms of entry wheel 5 of overtension measurement mechanism 3 finally leaves this mechanism through free gear 5 guiding.
