Each feature of the general principle of utility model.Specific design feature of the present utility model disclosed herein, including for example
Certain size, orientation, positioning and profile, partly it will be determined by the application and use environment of specific purpose.
Embodiment
Each embodiment of the present utility model is specific reference will be made to now, shows these with following description in the accompanying drawings
The example of embodiment.Although the utility model is combined with exemplary embodiment and is described, it will be understood that this specification
It is not intended to the utility model being limited to those exemplary embodiments.On the contrary, the utility model is intended to not only to cover these and shown
Example property embodiment, and covering can be included in the spirit and scope of the present utility model that are defined by the appended claims it
Interior various replacements, modification, equivalents and other embodiments.
Below in conjunction with the accompanying drawings, the utility model is specifically described.
Shown in Figure 2, which show a kind of draging for elevator provided with load early warning element of the present utility model
Leader tape, its structure mainly include：Along the cladding 1 of the Longitudinal extending of drawing belt；It is internal along Longitudinal extending in cladding (1)
And load-carrying unit 2 arranged in parallel；Along the load early warning element for being parallel to the extension of load-carrying unit 2 inside cladding 1
3；And the end coupling (not shown) positioned at the both ends of drawing belt, it has the signal electrically connected with load early warning element 3
Leading-out terminal (not shown), the wherein tensile strength of load early warning element 3 are less than the tensile strength of load-carrying unit 2, or described
The fracture strength of load early warning element 3 is less than the fracture strength of the load-carrying unit 2.
It is electrically connected in the elevator (not shown) including above-mentioned drawing belt, in addition to the signal leading-out terminal of end coupling
The detection warning device (not shown) connect.Detection warning device can be prompted using sound and light alarm mode or other display modes
State and operation irregularity occur for the drawing belt of elevator.The telecommunications that detection warning device is exported by detection signal leading-out terminal
Number, determine whether related electrical parameters exception occur, thus judge whether the load of drawing belt has exceeded preset limit value.
When the load that drawing belt is born exceedes preset limit value, the elongation of load early warning element 3 can exceed default elongation
Value, or tension failure can be produced prior to load-carrying unit 2, it now can determine whether that drawing belt is concurrent in abnormal operating state
Go out alarm or stop elevator work.
The related electrical parameters can be the various electrical parameters in signal transacting, such as impedance parameter, voltage parameter, electric current
Parameter etc., this depends on the characteristic of element and the characteristic of signal processing circuit, as long as these electrical parameters can be with load early warning
The elongation or fracture of element 3 and change.
Detection warning device can include audible alarm unit or visual alarm device, so as to send what can be humanly perceptible
Voice signal, visual signal etc. are any, for example, loudspeaker alarm information, displaying information on screen or diode displaying information
Deng.
The material of cladding 1 can be polyurethane material or elastomeric material, and transparent, translucent or opaque shape material all may be used
With.Obviously, help to observe inside drawing belt using the cladding 1 of transparent material, this helps intuitively to determine that load is pre-
The position of abnormal elongation or fracture occurs for alert element 3, and determines the degree of damage.For example, load early warning element 3 be broken it is several
Whether root, local anomaly elongation are serious.This is favourable for determining the measure needed for maintenance, such as, if it must at once change and drag
Leader tape, still can temporarily reduce load come work with etc. it is to be replaced.
Load-carrying unit 2 and 3 respective quantity of load early warning element are at least 1, and the two is distributed in cladding 1 side by side
In.When multiple load-carrying units 2 and an only load early warning element 3 be present, load early warning element 3 be arranged on two it is adjacent
Between load-carrying unit 2, so as to accurately detect the load condition of whole region between two adjacent load-carrying units 2.When depositing
In multiple load-carrying units 2, and the quantity of load early warning element 3 also for it is multiple when, multiple load early warning elements 3 respectively with
Multiple alternate intervals of load-carrying unit 2 are set, effectively to detect the load condition at the diverse location of the cross section of drawing belt.
When multiple load early warning elements 3 be present, the electric signal exported by multiple signal leading-out terminals is alarmed after testing
Device identifies, it can be determined that the loading conditions and damage distribution situation of whole drawing belt cross section.This aids in determining whether to drag
The degree of the damage of leader tape.For example, load early warning element 3 there are several fractures or there occurs local anomaly elongation, occur in traction
Where is the cross section of band.This is favourable for determining the measure needed for maintenance, such as, if traction must be changed at once
Band, still can temporarily reduce live load with etc. it is to be replaced.Now, detection warning device can have video display devices, with
The damaged condition of display drawing belt cross section directly perceived.
Load-carrying unit 2 can be the customary components that drawing belt uses, for example, steel wire rope, steel band, cordage, fiber or gold
Belong to braid over braid etc..Load early warning element 3 can be at least one in steel wire rope, steel band, cordage, fiber or metallic braid
Kind, as long as its tensile strength is strong less than the fracture of load-carrying unit 2 less than the tensile strength of load-carrying unit 2, or fracture strength
Degree.
The electric signal of load early warning element extraction is utilized according to the drawing belt of the present utility model for elevator, can be at any time
The working condition of the drawing belt for elevator is effectively monitored, therefore without being to judge drawing belt by regularly visual examination
It is no working properly, the drawing belt performance fault monitoring instrument more without specialty, therefore can effectively ensure the normal of drawing belt
Work, reduce maintaining cost.Even it can with accurate and visual understand load condition and damage on the whole cross section of drawing belt
Bad situation, so as to using most rational maintenance means.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to limit the utility model, or the utility model is defined to disclosed precise forms, and it will be apparent that root
According to above-mentioned teaching, much it can be changed and be changed.The purpose of selecting and describing the exemplary embodiment is that explain
Certain principles and its practical application of the present utility model, so that others skilled in the art can realize and utilize this
A variety of exemplaries of utility model and various chooses and changes.The scope of the utility model is anticipated
Limited by appended claims and its equivalents.
