Core is carried to be made of according to certain aligned transfer several sub- ropes, it is described per root rope by cordage around a few rear joint grafting and
At.
A kind of length accuracy control method of hanging belt, includes the following steps：
One, the length of sub- rope is controlled；
(1) setup parameter：
The specified pulling force of hanging belt：F
Sub- rope is pre-stretched pulling force：F1
Cordage is pre-stretched pulling force：F2
Sub- rope radical：X
The cordage number of turns in sub- rope：Q
Hanging belt effective length：L
Carry core diameter：D
Wherein, F1=F/X；F2=F/XQ；
(2) cordage is pre-stretched by F2 pulling force, and measures length L+D, made marks, method is in same cordage according to this
On measure the line segment that 2Q length is L+D successively, and enclosed around Q, connector grafting, at a root rope, made at closed annular by this method
More root ropes；
Two, the length of control carrying core
(1) every root rope is made to the tension test of F1 load, and records the length per root rope respectively, and is long according to sub- rope
Degree carries out sequence notation number；
(2) carrying core is made according to the length of sub- rope, then carrying core is made into specified pulling force pre-stretching experiment, measured and record
Length value；
(3) hanging belt is made in the carrying additional protective case of core, then does rated load tension test, measures simultaneously record length value,
As final lengths value of the hanging belt under rated load state.
Present invention has the advantages that：It is not more than ± 0.2% using hanging belt error in length made of this method, the state of hanging belt
Inside and outside standard regulation error range is ± 2%.According to the length phase under the volume load state between a plurality of hanging belt made of this method
0.04% is not more than to error.
Description of the drawings

There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the structural schematic diagram of neutron rope of the present invention；
Fig. 2 is the structural schematic diagram that core is carried in the present invention.
Specific implementation mode
The present invention is described further in conjunction with the accompanying drawings and embodiments.
A kind of hanging belt, including carrying core, the carrying core is made of several sub- ropes according to certain aligned transfer, described
It is formed around a few rear joint grafting by cordage per root rope.
A kind of length accuracy control method of hanging belt, includes the following steps：
One, the length of sub- rope is controlled；
(1) setup parameter：
The specified pulling force of hanging belt：F
Sub- rope is pre-stretched pulling force：F1
Cordage is pre-stretched pulling force：F2
Sub- rope radical：X
The cordage number of turns in sub- rope：Q
Hanging belt effective length：L
Carry core diameter：D
Wherein, F1=F/X；F2=F/XQ；
(2) cordage is pre-stretched by F2 pulling force, and measures length L+D, made marks, method is in same cordage according to this
On measure the line segment that 2Q length is L+D successively, and enclosed around Q, connector grafting, at a root rope, made at closed annular by this method
More root ropes；
Two, the length of control carrying core
(1) every root rope is made to the tension test of F1 load, and records the length per root rope respectively, and is long according to sub- rope
Degree carries out sequence notation number, is then fastened with adhesive tape every 1 meter of distance on sub- rope, sub- rope is avoided to scatter；
(2) according to the length of sub- rope, in the present embodiment：Length sequence from small to large the number of putting in order 1,2,3,4,5,6,7,
8,9,10,11,12,13,14,15,16, then when carrying core is made sub- rope pile up sequence for 1,3,5,7,9,11,13,15,6,14,
12,10,8,6,4,2, carrying core is made according to the length of sub- rope, then carrying core is made into specified pulling force pre-stretching experiment, measured simultaneously
Record length value is fastened core is carried every 1 meter of distance when carrying core stretches with adhesive tape, and carrying core is avoided to scatter,
Wherein, specified pulling force be according to the analysis and summary of previous similar product test data, by stock utilization is calculated, according to
