Abstract

The invention discloses a calibration stand of a tension monitoring stress hinge pin for a cable disengaging hook, which solves the problem that in the domestic prior art, the tension monitoring stress hinge pin cannot be calibrated. The technical scheme is as follows: the calibration stand comprises a calibration bracket and a hydraulic station with a hydraulic pressure indicator gauge, wherein an oil cylinder connected with the hydraulic station through an oil pipe is arranged on the calibration bracket; a shaft sleeve A and a shaft sleeve B are respectively mounted on two sides of the oil cylinder on the calibration bracket; locking plate adjusting ports are respectively arranged on the shaft sleeve A and the shaft sleeve B; shaft sleeve adjusting bolts are respectively arranged below the shaft sleeve A and the shaft sleeve B; a standard shaft is placed in the shaft sleeve A, and connected with a display and adjusting meter box through a lead; and the to-be-calibrated shaft is adjusted by comparing measured values of the to-be-calibrated shaft and the standard shaft through the display and adjusting meter box. The calibration stand can be used for calibrating the tension monitoring stress hinge pin for the cable disengaging hook at petrochemical docks.

Description

technical field

[0001] The invention belongs to equipment for calibrating measuring tools, and more specifically, relates to a calibrating platform for calibrating the accuracy and measuring precision of the tension monitoring stress pin of a cable-off hook. Background technique

[0002] Most of the modern petrochemical docks use intelligent mooring hooks, that is, the mooring hooks are equipped with tension monitoring stress pins, which are used to monitor and measure the tension of the cables during the loading and unloading process of ships berthing at the wharf in real time. The data is transmitted to the scene and displayed on the computer screen of the central control, so that the staff can reasonably control the scene of the terminal. Since the tension monitoring stress pin is a kind of tension measuring tool, the strain gauge in the tension monitoring stress pin will undergo plastic deformation after long-term use, which will reduce the accuracy and precision of the ...
