Abstract

PROBLEM TO BE SOLVED: To accurately judge a flexure quantity and display pressing force in relation to the flexure quantity by providing a flexure detecting body coming in contact with an adjacent belt to detect the flexure quantity, and a pressing force detecting means for supporting a pressing body and detecting the pressing force of the pressing body. SOLUTION: A flexure detecting body 3 is fitted to a pressing body 2 and provided with an expansible body 4 bent when coming in contact with a belt, and outputs a flexure signal when the expansible body 4 bends by a specified quantity. When the pressing body 2 presses the belt and the expansible body 4 bends by the specified quantity, a signal is outputted by a flexure quantity detecting means of the flexure detecting body 3. A pressing force detecting means inputs the signal to an AND part through wiring 6, and displays the pressing force on a display part 5. The pressing body 2 and the expansible body 4 are respectively brought into contact with the V-belt and pressed down from the upper part through a grip part body 1. Then the expansible body 4 enters the flexure detecting body 3, and the flexure quantity detecting means outputs the signal when reaching the specified flexure quantity.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt bending pressure measuring device for measuring a belt bending pressure.

[0002]

2. Description of the Related Art In general, when a predetermined pressing force is applied to a belt connecting a pump and a motor or the like, a belt is inspected for deterioration or tension of the belt based on the amount of deflection.
For example, as the one used in the application, a pressing force is applied to a belt connecting a hydraulic pump for a hydraulic elevator and a motor, and the deterioration and tension are measured by measuring the pressing force when the belt is bent by 10 mm. I have. Conventionally, in the measurement of the pressing force of the belt, the pressing force applied at that time is read from a scale while visually confirming that the operator has bent the belt by 10 mm. However, in the above-described conventional apparatus, the applied pressing force must be measured while maintaining the state in which the belt is bent by 10 mm. Further, since both the amount of bending and the pressing force are visually observed by an operator,
It is difficult to accurately read both at the same time. In order to solve this problem, Japanese Patent Application Laid-Open No.
Japanese Patent Publication No. 1902 discloses a pressing body movably supported by a grip portion to apply a pressing force, vibration detecting means for detecting vibration applied to the pressing body, and a vibration detecting means for detecting vibration by the vibration detecting means. A pressing force detecting means for detecting a pressing force applied to the pressing body, and a pressing force output unit for detecting a pressing force applied to the pressing body when vibration is detected by the vibration detecting means. A pressure measuring device has been proposed and put into practical use.

In the above-mentioned proposal, the amount of flexure is determined while looking at the scale at the tip of the pressing body. Therefore, there is a problem that it is difficult to make a visual judgment in a dark place or an installation position. Was.

[0004] It is an object of the present invention to accurately determine the amount of deflection,
An object of the present invention is to provide a belt bending pressure measuring device capable of displaying a pressing force with respect to the amount of bending.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pressing member for applying a pressing force to a belt to be measured and, when the pressing member presses the belt to be measured, the belt comes into contact with an adjacent belt to detect the amount of deflection. A gripping body provided with a deflection detecting body to be pressed, and a pressing detection means for supporting the pressing body and detecting a pressing force of the pressing body; and a gripping body provided on the gripping body, wherein the bending detecting body has a predetermined value of bending. This is attained by providing a display unit for displaying the pressing force at the time of pressing.

Is a clear button for clearing the pressing force displayed on the display unit 5. Reference numeral 9 denotes a pressing force detecting means incorporated in the grip portion main body 1. When the pressing body 2 presses the belt 24 and the elastic body 4 bends by a predetermined amount, the bending detecting means 10 of the bending detecting body 3 outputs a signal, The pressing force is input to the AND unit via the display unit 6, and the pressing force is displayed on the display unit 5.

Normally, four belts 24 (24 A, 2 A) are provided between the pulley 21 of the hydraulic pump 20 and the pulley 23 of the motor 22.
4B, 24C, 24D).

To detect the bending pressure of the V-belt 23C, first, as shown in FIG. 5, the measuring device is positioned, and the pressing body 2 is brought into contact with the V-belt 24C, and the elastic body 4 is brought into contact with the V-belt 24B. Next, when the telescopic member 4 is pushed down from above by way of the grip portion main body 1, the telescopic member 4 enters the deflection detecting member 3 and outputs a signal from the bending amount detecting means 10 when the state shown in FIG. on the other hand,
The pressing force of the pressing body 2 is measured by the pressing detecting means 9,
When the signal matches the previous signal, it is displayed on the display unit 5. Next, when detecting the bending pressure of the V-belt 24B, after pressing the clear button 8 to clear the display pressure, the pressing body 2 is brought into contact with the V-belt 24B and the telescopic body 4 is brought into contact with the V-belt 24A, and the same method as above is performed. To detect.

As described above, since the amount of bending is accurately measured by the bending elastic body 4 and the pressing force is displayed in accordance with the measurement result, the bending pressure of the belt can be accurately measured.
