Embodiment
In order to make those skilled in the art person understand technical scheme among the application better, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the application's protection.
A kind of portable tension measuring instrument that Fig. 1 provides for the embodiment of the present application face structural representation.
The side-looking structural representation of a kind of portable tension measuring instrument that Fig. 2 provides for the embodiment of the present application.
As depicted in figs. 1 and 2, this portable tension measuring instrument comprises: tension bracket 1, first locating device 2, second locating device 3, slide bar 4, bracing or strutting arrangement 5, measurement mechanism (not shown) and display device 6.
Wherein: tension bracket 1 is provided with two tension adjustment grooves 7 and chute 8, about first locating device 3 and second locating device 4 are separately fixed in two tension adjustment grooves 7, slide bar 4 is fixed in the chute 8 of tension bracket 1 movably, can slide up and down along chute 8, bracing or strutting arrangement 5 is fixed on the lower end of chute, but not with first locating device 2 and second locating device 3 on same straight line, measurement mechanism is fixed on the tension bracket 1, and be connected with the upper end of slide bar 4, measure the size of the power on the bracing or strutting arrangement 5 by slide bar 4, display device 6 links to each other with measurement mechanism, and the measurement result of measurement mechanism is shown.
In the embodiment of the present application, first locating device 2, second locating device 3, bracing or strutting arrangement 5 can be cylinder or pulley, are used for fixing electric wire to be measured when measuring, and in order to prevent that the insulated hull of electric wire to be measured is galled, above-mentioned three preferably uses pulley.Ask among the embodiment in basis, tension bracket 1 upper hopper chute 8 is arranged on the perpendicular bisector of first locating device 2 and second locating device, 3 lines.Display device 6 in the embodiment of the present application, is preferably digital indicator including, but not limited to pointer and scale or digital indicator.
A kind of portable tension measuring instrument fundamental diagram that Fig. 3 provides for the embodiment of the present application.
When the portable tension measuring instrument that uses the embodiment of the present application to provide, as shown in Figure 3,11 is electric wire to be measured among the figure, and bracing or strutting arrangement 5 is positioned at the top of first locating device 2 and second locating device, 3 lines.Electric wire 11 passes from the downside of first locating device 2, passes the upside of bracing or strutting arrangement 5 again, and the downside from second locating device 3 passes at last.Therefore electric wire 11 can produce downward acting force to bracing or strutting arrangement 5 under the effect of tension force.As shown in FIG., the electric wire 11 between first locating device 2, second locating device 3 and the bracing or strutting arrangement 5 is α with the angle that surface level is respectively, supposes that electric wire 11 is F1 in the power that left makes progress, and the power on right is F2, and it makes a concerted effort to be F.Therefore and F1 equals F2, in theory also equals the tension force of electric wire 11, utilizes the exert oneself F with joint efforts of F1 and F2 of measurement mechanism measurements just can measure the tension force of electric wire 11.
In theory when the size at α angle is set at 30 °, when promptly the angle between first locating device 2, second locating device 3 and the bracing or strutting arrangement 5 is 120 °,
F=F1=F2 then, promptly the size of F1 and F2 equals F size with joint efforts.
But in actual measurement, when the α angle is 30 °, because angle is excessive, under the effect of tension force, friction force between electric wire 11 and first locating device 2, second ejection device 3 and the bracing or strutting arrangement 5 can be excessive, causes measuring producing than mistake, makes the differing in size in the size of the F that makes a concerted effort of F1 and F2.Through experimental verification, adjust first locating device 2 and second position of locating device 3 in tension adjustment groove 2, making α angle size is 14.5 °, when promptly the angle between first locating device 2, second locating device 3 and the bracing or strutting arrangement 5 is 151 °, this moment, the angle at α angle was moderate, friction force is less, and the size of tension force F1 and F2 is 2 times of the F that makes a concerted effort.Therefore in the embodiment of the present application, the size at α angle is set at 14.5 °, and correspondingly the angle between first locating device 2, second locating device 3 and the bracing or strutting arrangement 5 is 151 °.Those of ordinary skills should be understood that the employing of α angle is the application's preferred embodiments for 14.5 ° in addition, in other embodiments, can also select other angle, should not constitute the restriction to the application.
In Fig. 3 (a) and Fig. 3 (b), the F with joint efforts of F1 and F2 is a pulling force to the acting force of bracing or strutting arrangement 5, so measurement mechanism should be selected tension measuring device.
In other embodiment of the application, bracing or strutting arrangement 5 can also be positioned at the below of first locating device 2 and second locating device, 3 lines, and wearing of electric wire 11 can also be as shown in Figure 4 around mode.The another kind of portable tension measuring instrument fundamental diagram that Fig. 4 provides for the embodiment of the present application.
As shown in Figure 4, the size at α angle is set at 14.5 ° equally among the figure, so F1=F2=2F, F is a pressure to the acting force of bracing or strutting arrangement 5 but make a concerted effort this moment, and therefore this moment, measurement mechanism was answered the selection pressure measurement mechanism.
In other embodiment of the application, this portable tension measuring instrument can also comprise:
The portable tension measuring instrument that the embodiment of the present application provides utilizes mechanics principle, and by making a concerted effort of direct measurement cable strain, indirect calculation obtains the tension force of cable then, this apparatus structure is simple, and cost is lower, does not need repairing substantially, and compact volume and convenience can be carried, the convenient use.
The above only is the application's a preferred implementation, makes those skilled in the art can understand or realize the application.Multiple modification to these embodiment will be conspicuous to one skilled in the art, and defined herein General Principle can realize under the situation of the spirit or scope that do not break away from the application in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
