Abstract
The present invention and aeronautical technology have relationship.Knot device is made of two pillars, and there are two roller and clips for tool on one of pillar, fixes third roller on second pillar.Two pillars are fixed on load floor, and pillar distance is equal to knot length.Roll shaft is located at a plane, and roller diameter is equal to spool diameter.To ensure that load seam length determines distance.Cutting executes under a load, and rope end portion breaks into knot that can be undone by a pull.Rope end portion is placed in fixture, and then rope drop rope is wrapped on two rollers, and the second end is connect by third roller with constant weight object.After spending one section of seclected time, the fixed special clip of installation knot length.Rope drop rope intensity increases and knot difference in length reduces (raising of knot dimensional accuracy).
Description
The present invention and aeronautical technology have relationship, are specifically used for production rope drop rope knot.
The rope of hanger and according to Russian Federation patent № 2141445, MPC B66C1/18 outside helicopter；In do
Method is as prototype；Above-mentioned knot way is described as follows: after rope drop rope is cut, rope lapping ends combine and the rope shape of middle section
Cyclization.This way considers to cut load for the 1-2% of rope failing load, and rope lapping ends combine, and the knot after suture is put into
Next knot, then all knots are turned-out, and inside becomes outside.This way major defect: due to graticule position difference,
In conjunction with a possibility that precision and suture markers linear deflection, knot length inaccuracy.
Main target of the present invention include: rope drop rope intensity increase and knot difference in length reduce (knot dimensional accuracy mentions
It is high).
Above-mentioned target examines record due to knot way and cuts the 1-2% that load is rope failing load, and rope end portion breaks into knot that can be undone by a pull
It realizes.According to concept of the invention, rope drop rope is cut to be executed using special device, and rope end portion is placed in fixture, then Suo Jiangsheng
It is wrapped on two rollers, the second end is connect by third roller with constant weight object.After spending one section of seclected time, knot length is installed
Fixed special clip.All knot durations of load application of one rope drop rope are the same.After knot is removed, free end needs push down seam
It closes.In local seam tapes band appropriate when knot is reinforced.
Knot device is made of two pillars, and there are two roller and clips for tool on one of pillar, on second pillar
Fixed third roller.Two pillars are fixed on load floor, and pillar distance is equal to knot length.Roll shaft is located at a plane,
Roller diameter is equal to spool diameter.The position for the other end that rope end portion and nearest roller and the roller are connect with band and weight it
Between distance based on designated length determine, to ensure load seam length.
Therefore, due to determining the distance between knot length roller when the present invention uses, tensile load is big and time etc. because
Element is constant before clamping element is fixed, and knot length accuracy is caused to improve.Using the rope drop rope of this way production than other ropes
Rope failing load is big.
Knot device is detailed in Fig. 1, and 2,3,4.
Fig. 1: side view；
Fig. 2: top view；
Fig. 3: detail drawing А；
Fig. 4: detail drawing B.
Knot device is made of two pillars, and pillar is fixed on load floor.On first pillar have third, No. four
Roller and No. five clip.The position for the other end that No. four roller and No. five clip and third roller are connect with band and weight
It the distance between sets and to be determined according to load seam length.Living at second has No. six roller on son.Third, four, No. six roll shafts
Positioned at a plane, roller diameter is equal to spool diameter (not shown).No. seven band is at load (1-2% of failing load)
Cut: No. eight end is fixed using No. five clip, after being wrapped on No. four roller, continues to be wrapped on No. six roller.The
No. seven bands are by the way that after third roller, No. nine end is connect with No. ten weight.When all knot loads of one rope drop rope
Between it is the same.The length that knots is fixed using ride on Bus No. 11 clip.After the installation of ride on Bus No. 11 clip, the length that knots cannot become.No. ten
After weight separates, knot is removed.No. nine end needs to push down with No. seven band and complete load seam.Knot reinforce when
No. seven band of place suture appropriate.
