Description
Technical field
The present invention relates to rope technique field, and in particular to a kind of rope that may indicate that pulling force..
Background technology
Rope is the article commonly used in daily life and projects.In rope in actual use, in some applications
Field, generally require to apply rope predetermined tension force.For example, in textile mills, whether workshop building or textile mills
In practical application, it is related to many places needed using rope.In some occasions, it is necessary to apply certain predetermined tension to rope
So that rope is in tensioning state.And predetermined tension according to setting value sometimes for applying, it is impossible to arbitrarily apply.Therefore, generally
Need, when applying predetermined tension to rope, to measure pre-tension using precision instrument.But some occasions, it has not been convenient to make
With precision instrument, moreover precision instrument is also costly, virtually adds entreprise cost.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 require to set the drag-line with certain pulling force and hold electric wire stake to avoid electric wire stake from falling
Under.During this, generally require using the pulling force of the measurement drag-line such as instrument of precision to correspond to actual needs.However, these
Often volume is larger or not Portable belt for accurate instrument.For example, worker, when using wireline operation, operating environment is probably mountain
The positions such as slope, high-altitude.In these local operations, if the equipment entrained by workpeople can be reduced as far as possible, work can be greatly reduced
The burden of people, save muscle power.Thus, 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.
The content of the invention
Above-mentioned technical problem be present for prior art, the present invention provides a kind of rope that may indicate that pulling force and its preparation side
Method, the size of pulling force is directly indicated by observing the elongation to rope during rope application pulling force.
The present invention to achieve the above object and use technical scheme be：A kind of rope that may indicate that pulling force, including rope
Main body, clad and marker；It is characterized in that：Rope main body is coated with clad, and certain length is provided with outside clad
The marker of degree；Relative displacement does not occur between clad and rope main body；Centre position on the length direction of marker
Fixed base is provided with, fixes marker and clad in fixed base position, makes it that overall relative displacement not occur；Bag
Relative displacement does not occur between coating and rope main body, clad can be occurred relatively with fixed base with the marker of outer portion
Displacement；Using fixed base as symmetry axis on clad, the 4th pulling force index line around clad, the are symmetrically arranged with successively
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 up of transparent material, in order to observe the position of pulling force index line.
Preferably, clad is made of rubber.Because steel wire rope is usually to be twisted with the fingers more steel wires by the way of twisting
Conjunction forms, thus the surface of rope main body is typically rough, is unfavorable for the mark of pulling force index line.Therefore, in rope
The outside of main body sets clad（Preferably quality of rubber materials is made）, and make it that relative displacement not occur with rope main body, with profit
Indicate wire tag on clad in pulling force.Certainly, if the surface of rope main body can conveniently set up pulling force index line, then
Clad can be omitted, directly marker is arranged on outside rope main body, and correspondingly adjustment may indicate that the knot of the rope of pulling force
Corresponding Terminology in structure and following methods for determining pulling force instruction line position, but essential idea is constant.
