Fig. 2 shows the sectional view of the drawing belt according to the present invention for elevator.
Wherein, the label declaration in attached drawing is as follows:1- covering body;2- load-carrying unit;3- load early warning element.
It is to be appreciated that attached drawing is not necessarily drawn to scale, it illustrates in a way by the sheet that simplifies
Each feature of the basic principle of invention.Specific design feature of the invention disclosed herein, including for example specific ruler
Very little, orientation, positioning and shape, will partly be determined by the application of specific purpose and use environment.
Specific embodiment
It specific reference will be made to each embodiment of the invention now, show these implementations in the drawings and the following description
The example of example.Although the present invention is combined with exemplary embodiment and is described, it will be understood that this specification is not intended to
Limit the invention to those exemplary embodiments.On the contrary, the present invention is directed to not only cover these exemplary embodiments, and cover
Lid can be included in it is within the spirit and scope of the present invention being defined by the appended claims it is various replacement, modification, etc.
Effect form and other embodiments.
With reference to the accompanying drawing, the present invention is specifically described.
It is shown in Figure 2, which show a kind of drawing belt for elevator equipped with load early warning element of the invention,
Its structure mainly includes:Along the covering body 1 of drawing belt longitudinally extended;It is internal along longitudinal extension and flat in covering body (1)
The load-carrying unit 2 of row arrangement;Along the load early warning element 3 for being parallel to the extension of load-carrying unit 2 inside covering body 1;With
And the end coupling (not shown) positioned at the both ends of drawing belt, there is the signal being electrically connected with load early warning element 3 to draw
Terminal (not shown), wherein the tensile strength of load early warning element 3 is lower than the tensile strength or the load of load-carrying unit 2
The breaking strength of early warning element 3 is lower than the breaking strength of the load-carrying unit 2.
It further include being electrically connected with the signal leading-out terminal of end coupling in the elevator (not shown) for including above-mentioned drawing belt
The detection warning device (not shown) connect.Sound-light alarm mode or other display modes can be used to prompt in detection warning device
It states and operation irregularity occurs for the drawing belt of elevator.It detects warning device and passes through the telecommunications of detection signal leading-out terminal output
Number, it determines whether related electrical parameters exception occur, thus judges whether the load of drawing belt has been more than preset limit value.
When the load that drawing belt is born is more than preset limit value, the elongation of load early warning element 3 can be more than default elongation
Value, or tension failure can be generated prior to load-carrying unit 2, it is concurrent to can determine whether that drawing belt has been in abnormal operating state at this time
It alarms out or stops elevator and work.
The related electrical parameters can be the various electrical parameters in signal processing, 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 may include audible alarm unit or visual alarm device, thus what sending 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 covering body 1 can be polyurethane material or rubber material, and transparent, translucent or opaque shape material all may be used
With.Obviously, help to observe inside drawing belt using the covering body of transparent material 1, this helps intuitively to determine that load is pre-
Alert element 3 is abnormal the position of elongation or fracture, 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 advantageous for measure needed for determining maintenance, such as, if it replacement must drag at once
Leader tape, still can temporarily reduce load come work with etc. it is to be replaced.
Load-carrying unit 2 and the respective quantity of load early warning element 3 are at least 1, and the two is distributed in covering body 1 side by side
In.There are multiple load-carrying units 2 and when only one load early warning element 3, load early warning element 3 is arranged two 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 when the quantity of load early warning element 3 is also multiple, multiple load early warning elements 3 respectively with
Multiple 2 alternate intervals of load-carrying unit settings, the load condition at different location so that the cross section of drawing belt is effectively detected.
When there are multiple load early warning elements 3, alarmed by the electric signal that multiple signal leading-out terminals export through detection
Device identification, it can be determined that the loading conditions and damage distribution situation of entire 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 to be broken or have occurred local anomaly elongation, occur in traction
Where is the cross section of band.This is advantageous for measure needed for determining maintenance, such as, if it must replacement traction at once
Band, still can temporarily reduce workload with etc. it is to be replaced.At this point, detection warning device can have video display devices, with
The damaged condition of intuitive display drawing belt cross section.
The customary components that load-carrying unit 2 can use for drawing belt, for example, wirerope, steel band, cordage, fiber or gold
Belong to braid over braid etc..Load early warning element 3 can be at least one in wirerope, steel band, cordage, fiber or metallic braid
Kind, as long as its tensile strength is strong lower than the fracture of load-carrying unit 2 lower than the tensile strength of load-carrying unit 2 or breaking strength
Degree.
The electric signal that drawing belt according to the present invention for elevator utilizes load early warning element to draw, can at any time effectively
Ground monitoring for elevator drawing belt working condition, there is no need to judged by regularly visual examination drawing belt whether work
Make normally, there are no the drawing belt performance fault monitoring instruments for needing profession, therefore can effectively guarantee the normal work of drawing belt,
Reduce maintenance cost.Load condition and damage feelings on the entire cross section of drawing belt can be even understood accurate and visually
Condition, thus using most reasonable maintenance means.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to the exhaustive present invention, or limits the invention to disclosed precise forms, and it will be apparent that according to the above instruction,
Many changes and variations can be made.The purpose of selecting and describing the exemplary embodiment is that explaining of the invention specific
Principle and its practical application, so that others skilled in the art can be realized and utilize of the invention a variety of different
Exemplary implementation scheme and various chooses and changes.The scope of the present invention be intended to by appended claims and its
Equivalent form is limited.
