Embodiment 1

[0035] During use, one end of the rope is fixed on the first fixing part 16 of the tension sensor 31, and after the rope passes through the hole 131 of the fixed middle plate 13, the other end is fixed on the second fixing part 24 of the moving plate 22. Pay attention to adjust the length of the rope when fixing. By default, the tension sensor 31 on the first fixed end plate 11 is a standard sensor, which is used to calibrate the tension sensor 32 or test the ultimate tension of the rope. If other tension sensors 31 need to be calibrated, the standard sensor is replaced with the sensor to be calibrated, and the standard tension sensor 32 is used for calibration.

Embodiment 2

[0037] A tension sensor 32 is installed on the rope, and the installation of the tension sensor 32 is determined according to actual test requirements. If the ultimate tension of the rope is tested, the tension sensor 32 does not need to be installed; if the tension sensor 31 needs to be calibrated, the standard tension sensor 32 is installed. If the tension sensor 32 needs to be calibrated, either a standard tension sensor 31 can be used for calibration, or a standard tension sensor 32 can be connected in series next to the measured tension sensor 32 for calibration. Simultaneous calibration can also be performed by connecting multiple tension sensors 32 with calibration in series.

Embodiment 3

[0039] When using vertically, close the jack 21 valves, raise the push rod of the jack 21 with a manual rocker, so that the movable plate 22 moves and tightens the rope. The greater the travel of the moving plate 22, the greater the pull and tension of the rope. Through the standard tension sensor 31 or tension sensor 32, the tension value on the rope can be read in real time. By comparing the readings of the sensor under test with the readings of the standard sensor, the sensor under test can be calibrated.

[0040] After the measurement is completed, the valve of the jack 21 is opened, and the movable plate 22 is reset, so that the next experiment can be carried out.

Abstract

The invention discloses a manual pull and tension test and sensor calibration device. The device comprises a support portion, a power portion, a measurement portion, and a reset portion. The support portion comprises a first fixed end plate, a second fixed end plate, a fixed middle plate, a first support rod set, a second support rod set, and a first fixing piece. The power portion comprises at least two jacks, a moving plate, a firmware, a second fixing piece, and a pulling piece. The measurement portion comprises a pull sensor and / or a tension sensor. The reset portion is used for resettingthe moving plate. The manual pull and tension test and sensor calibration device solves the problems that a traditional automatic pull test bench is large in size, high in price, fixed in range, and difficult to meet the calibration requirements of small pull and tension sensors, is small in size, convenient to move, flexible and convenient to adjust manually, and has a large effective stroke.

Description

technical field [0001] The invention belongs to the field of sensor testing, in particular to a device for manual tension and tension testing and sensor calibration. Background technique [0002] The existing tensile testing device adopts a miniature DC servo motor as a power source, and a single-chip microcomputer displays test data and test status in real time, and the control of the test process is realized through the automatic control of the single-chip microcomputer.
