Detailed Description
Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the present application, and is not intended to be exhaustive or to limit the scope of the application.
Referring to fig. 1A, 1B, 1C, and 1D, the present application provides a guide wheel stress detection device, which includes a fixed bracket 2, a guide wheel bracket 3, a bracket rotation shaft 4, a guide wheel shaft 5, a guide wheel 6, and a pressure sensor 7.
Wherein, leading wheel 6 is used for conflicting guide rail 8, and leading wheel 6 rotationally connects in leading wheel axle 5, and leading wheel axle 5 connects in leading wheel support 3.
Referring to fig. 2, the guide wheel bracket 3 is connected to the bracket rotating shaft 4 such that the guide wheel bracket 3 can rotate about the axis of the bracket rotating shaft 4. Of course, the guide wheel bracket 3 is not shown in a screwed-out state in the actual working process due to the interference relationship between the guide rail 8 and the guide wheel 6.
The holder rotating shaft 4 is connected to the fixed holder 2. The fixed support 2 is provided with a mounting hole 1, and the guide wheel stress detection device can be mounted on the carrying equipment 9 through the mounting hole 1.
The pressure sensor 7 may be provided on the fixed bracket 2, and the guide wheel bracket 3 is simultaneously supported by the pressure sensor 7 when the guide wheel 6 is pressed by the guide rail 8. Of course, the pressure sensor 7 can also be installed on the guide wheel bracket 3, so that the guide wheel bracket 3 can be abutted against the fixed bracket 2 through the pressure sensor 7.
It can be understood that under the normal working state of the guide wheel stress detection device, the guide wheel 6 is abutted against the guide rail 8, and the stress direction of the guide wheel 6 is parallel to that of the pressure sensor 7.
Referring to fig. 3, according to the lever principle, the support rotating shaft 4 is a rotating shaft of the guide wheel support 3, and the resultant moment applied to the guide wheel support 3 is zero in the static equilibrium state.
That is, F1 × L1 ═ F2 × L2
F1-the pressure of the guide rail 8 to which the guide wheel 6 (or guide wheel bracket 3) is subjected;
l1-the distance between the line of action of F1 and the axis of the support rotation axis 4;
f2 — supporting force (or pressure) of the pressure sensor 7 received by the guide wheel bracket 3;
l2-the distance between the line of action of F2 and the axis of the support rotation shaft 4.
It can be understood that the first moment (the moment F1 × L1 that urges the guide wheel frame 3 to rotate clockwise in fig. 3) that the guide wheel frame 3 receives is equal to the second moment (the moment F2 × L2 that urges the guide wheel frame 3 to rotate counterclockwise in fig. 3) that the guide wheel frame 3 receives.
And because the force applied by the F2 and the pressure sensor 7 is a pair of mutual acting forces, the magnitudes are equal and the directions are opposite, that is, the pressure sensor 7 shows the pressure magnitude equal to that of F2. The data of F2, L1 and L2 are measured, and the data of F1 can be obtained through calculation, and the stress of the guide wheel 6 is obtained.
Preferably, the force point of the pressure sensor 7 and the geometric center of the guide wheel 6 are located on the same horizontal plane (with the same height), so that the detected force of the guide wheel 6 is closer to the real situation.
Preferably, the guide wheel shaft 5 is located between the support rotation shaft 4 and the pressure sensor 7, as seen in the direction in which the guide wheel 6 is pressed by the guide rail 8. The pressure sensor 7 has sufficient installation space, and the device for detecting the stress of the guide wheel is miniaturized. Of course, the pressure sensor 7 may also coincide with the guide wheel 6, or the pressure sensor 7 may be located between the guide wheel shaft 5 and the stand rotation shaft 4, as seen from the above-mentioned viewing direction.
Can understand, the leading wheel atress detection device that this application provided can be used for original leading wheel structure on the interim replacement haulage equipment, obtains the atress condition of leading wheel. Can make leading wheel atress detection device the same with original leading wheel structure mounted position through mounting hole 1, make leading wheel 6's atress condition the same, the testing result is more accurate.
After the detection is finished, the original guide wheel structure can be replaced. The guide wheel stress detection device can replace the original guide wheel to undertake a guide task, and the service life of the guide wheel stress detection device is effectively prolonged.
This application has compensatied the vacancy in this aspect of unable measurement leading wheel pressure among the prior art, the atress situation of mastering the leading wheel that can be more accurate to judge whether need strengthen the intensity of leading wheel, perhaps suitably reduce the intensity of leading wheel and come the reduce cost.
