Description
Technical field
The present invention relates to rope technique fields, and in particular to one kind can indicate the rope of pulling force.
Background technique
Rope is common article in daily life and projects.Rope in actual use, in certain applications
Field generally requires to apply scheduled tension to rope.For example, in textile mills, whether workshop building or textile mills
In practical application, it is related to much needing the place using rope.In certain occasions, need to apply rope certain predetermined tension
So that rope is in tensioning state.And predetermined tension cannot arbitrarily apply sometimes for applying according to setting value.Therefore, usually
It needs to measure pre-tension using precision instrument when applying predetermined tension to rope.But certain occasions, it has not been convenient to make
Entreprise cost is virtually increased moreover precision instrument is also more expensive with precision instrument.For another example, in rural area, electric power
Electric wire is fixed on the top of electric wire stake and realizes long-distance sand transport by conveying often by spaced electric wire stake.And
In the installation process of electric wire stake, generally requiring setting has the drag-line of certain pulling force and holds electric wire stake and fall to avoid electric wire stake
Under.During this, the pulling force of the measurement drag-line such as accurate instrument is often required to use to correspond to actual needs.However, these
Often volume is larger or not Portable belt for accurate instrument.For example, worker is when using wireline operation, operating environment may be mountain
The positions such as slope, high-altitude.In these local operations, if equipment entrained by workpeople can be reduced to the greatest extent, work can be greatly reduced
The burden of people saves physical strength.As a result, when using rope, how predetermined tension is applied to rope, but do not carry pulling force inspection
The problem of measurement equipment is a long-standing problem workpeople.
Summary of the invention
For the prior art there are above-mentioned technical problem, the present invention provides a kind of rope and its preparation side that can indicate pulling force
Method directly indicates the elongation of rope during rope application pulling force the size of pulling force by observing.
The present invention to achieve the above object and the technical solution adopted is that: one kind can indicate the rope of pulling force, including rope
Main body, clad and marker；It is characterized by: rope main body is coated with clad, certain length is provided with outside clad
The marker of degree；Relative displacement does not occur between clad and rope main body；Middle position on the length direction of marker
It is provided with fixed base, marker and clad are fixed in fixed base position, make it that whole relative displacement not occur；Packet
Relative displacement does not occur between coating and rope main body, clad can occur with fixed base with the marker of outer portion opposite
Displacement；Using fixed base as symmetry axis on clad, it is successively symmetrically arranged with the 4th pulling force index line around clad, the
Three pulling force index lines, the second pulling force index line, the first pulling force index line and zero pulling force index line；Zero pulling force index line and instruction
The edge line at the both ends on the length direction of layer is concordant.
Preferably, marker is made of transparent material, in order to observe the position of pulling force index line.
Preferably, clad is made of rubber.Because the mode that twisting is usually used in wirerope twists more steel wires
It closes, thus the surface of rope main body is usually rough, is unfavorable for the label of pulling force index line.Therefore, in rope
Clad (preferably rubber material is made) is arranged in the outside of main body, and makes it that relative displacement not occur with rope main body, with benefit
In pulling force instruction wire tag on clad.Certainly, if the surface of rope main body can conveniently set up pulling force index line, then
It can be omitted clad, directly marker be arranged outside rope main body, and correspondingly adjustment can indicate the knot of the rope of pulling force
Corresponding Terminology in the method for structure and following determining pulling force instruction line positions, but essential idea is constant.
Preferably, the 4th pulling force index line, third pulling force index line, the second pulling force index line, the first pulling force index line with
And zero pulling force index line be different colours, in order to intuitively distinguish pulling force size；It is further preferred that the 4th pulling force index line is
Black, third pulling force index line are red, the second pulling force index line be it is orange, the first pulling force index line is yellow, and zero pulling force refers to
Timberline is blue.
Preferably, the 4th pulling force index line is cord break strength index line, and third pulling force index line is 80% cord break
Strength index line, the second pulling force index line are 50% cord break strength index line, and the first pulling force index line is 20% cord break
Strength index line, the index line that zero pulling force index line is pulling force when being zero.
Preferably, a plurality of pulling force index line for indicating different pulling force sizes of setting can be selected according to actual needs, more
Preferably, a plurality of pulling force index line is provided directly as to the form of graduated scale, convenient for directly reading the pulling force born on rope.
The position of each pulling force index line determines by the following method on clad, the specific steps are as follows:
1) the rope main body and clad for being used to prepare the rope that can indicate pulling force are chosen, rope main body is coated with cladding
Layer；Intercepted into the different test rope of 15-20 segment length；
2) the test rope that 4 equal lengths are taken under each length is setting test rope using universal testing machine

Index line；
3) between zero pulling force index line and reference line, the first pulling force index line, the second pulling force index line, successively delimited
Three pulling force index lines and the 4th pulling force index line；
4) marker is arranged outside clad, is overlapped the fixed base of marker with the reference line on clad, and
Marker and clad are fixed in fixed base position, it is made not occur whole relative displacement, but clad can with it is solid
Determine baseline and relative displacement is occurred with the marker of outer portion；The edge line at the both ends on the length direction of marker refers to zero pulling force
Timberline is concordant, obtains the rope that can indicate pulling force therefrom.
Beneficial effects of the present invention:
The beneficial effects of the present invention are: the present invention provides the ropes and preparation method thereof that one kind can indicate pulling force.This energy
Enough during tubing sections, scheduled tension can be applied to rope without using pull test instrument.It is simple and reliable, it reduces
Worker carries in operation the equipment such as accurate tension tester, has saved physical strength.For example, when by this pulling force of indicating
When rope is used as the drag-line of electric wire stake, the first pulling force is set as required predetermined pull value, when construction operation, can refer to this
Show that the rope of pulling force carries out application pulling force, when the first pulling force index line is concordant with the edge line of marker, that is, can determine to drawing
