[embodiment]
See also Fig. 1 to Fig. 4, the utility model rope tension measurement instrument comprises force-sensing sensor 2, brachium pontis 1, point device, pressure point device, rope binding clasp 5 and display device.Brachium pontis 1 becomes the variable cross section shape according to the equal strength principle design, and is provided with handle (not label).In the present embodiment, point device is two fulcrum pulleys 3, two fulcrum pulleys 3 are installed in the two ends of brachium pontis 1 respectively, these two fulcrum pulleys 3 are in sustained height, its effect mainly is will be positioned preposition by measuring rope 12 rapidly, also can be provided with the location in brachium pontis 1 two ends by the smooth deep-slotted chip breaker of measuring rope 12 certainly.Display device comprises circuit board 9, display 10 and the button 11 that is installed on the brachium pontis 1, and this circuit board 9, display 10 and button 11 electrically connect.Force-sensing sensor 2 one ends are supported on the position of brachium pontis 1 near the middle part, are the middle part that is supported on brachium pontis 1 in this embodiment, these force-sensing sensor 2 other end connecting strand binding clasps 5, and this force-sensing sensor 2 electrically connects with circuit board 9.Rope binding clasp 5 comprises matrix 15, the pressure point device, screw leading screw 6, handwheel 7 and limited block 8, matrix 15 sides are provided with " [" opening 13, in order to be inserted in from the side tensioning by measuring rope 12, assurance can be unloaded and can measure by measuring rope 12, limited block 8 is fixedly mounted on the upper side wall of this opening 13, handwheel 7 with screw leading screw 6 one ends and link to each other, this other end that screws leading screw 6 runs through the lower wall of opening 13, thereby making this screw leading screw 6 parts is placed in this opening 13, and should be connected with the pressure point device by end, the pressure point device comprises a pressure point pulley 4 and the movable pulley base 14 of this pressure point pulley 4 on the right side wall of matrix 15 openings 13 of installing, and by forcing in this handwheel 7 pressure point pulley 4 is being slided up and down under the effect that screws leading screw 6 in opening 13.Two fulcrum pulleys 3, pressure point pulley 4 and 8 of limited blocks are formed with the gap, are to place in this gap when measuring by measuring rope 12, and two fulcrum pulleys 3 are a setting value with limited block 8 spacing and the drop on the vertical direction in the horizontal direction respectively.
In use, push button 11, unclamp rope binding clasp 5 earlier, to be inserted in the opening 13 of rope binding clasp 5 sides by measuring rope 12 and place on the pressure point pulley 4, run through gap between two fulcrum pulleys 3 and the pressure point pulley 4 by measuring rope 12, tighten by handwheel 7 and screw leading screw 6, can make to place being moved up by measuring rope 12 on the pressure point pulley 4 until arriving limited block 8, after reaching this state, the cord clip angle of pressure point pulley 4 both sides is changeless.Because of rope binding clasp 5 links to each other with force-sensing sensor 2, so 4 couples of pulley thrust T that produced by measuring rope 12 of pressure point pulley can finally act on the force-sensing sensor 2, these force-sensing sensor 2 output signals, through being presented on the display 10 after the circuit computing on the circuit board 9, correction, the amplification, this numerical value that demonstrates is by the Suo LaliF of measuring rope 12.Wherein, can be calculated by following formula by the Suo LaliF of measuring rope 12: during system balancing, T=2F * cos (a/2), T is pulley thrust, a be pressure point pulley 4 both sides by the angle of 12 of measuring ropes, because two fulcrum pulleys 3 are a setting value with limited block 8 spacing and the drop on the vertical direction in the horizontal direction respectively, so this angle a is a definite value.
Described brachium pontis 1 and force-sensing sensor 2 will have enough rigidity, fulcrum pulley 3, pressure point pulley 4, and the limited block 8 of rope binding clasp 5 have enough hardness could guarantee that this rope tension measurement instrument has higher precision.Describedly comprised side tension cords such as various twisted wires that steel or other materials make, cable, rope by measuring rope 12.High more by the good more measuring accuracy of the elastic performance of measuring rope 12.All kinds ofly undertaken before Suo Lali measures by measuring rope 12, instrument all must carry out correct demarcation.
