Embodiment 1

[0028] The winch wire rope tension measuring device includes a winch drum support 1, a wire rope drum 2 and a bearing seat 4, the drum support 1 is equipped with a bearing seat, the bearing seat 4 is equipped with a wire rope drum 2, and the bearing seat 4 is equipped with a wire rope force sensor 5 and wire rope speed sensor 3.

[0029] The wire rope speed measuring sensor 3 is a gear speed measuring method. The speed measuring sensor is equipped with a small gear, and a matching large gear is assembled on the reel shaft. The large gear and the reel shaft rotate synchronously. The speed measuring sensor 3 measures the angular velocity and the rotational speed of the pinion laps passed. The wire rope load cell is a load cell.

Embodiment 2

[0031] The measurement method of the wire rope tension measuring device of the winch, the steps of measuring the wire rope tension by the measuring device, measuring the force of the wire rope force sensor installed on the bearing housing, measuring the data of the wire rope speed sensor, and determining the length of the wire rope and its position on the wire rope drum , the wire rope force is calculated from the position of the wire rope on the wire rope drum to determine the tension of the wire rope.

[0032] Measuring the force of the wire rope load cell installed on the bearing housing is to measure the force of the load cell of the wire rope installed. The wire rope speed sensor is a gear speed measurement method. The speed sensor is equipped with a small gear, and a paired large gear is installed on the reel shaft. The large gear and the reel shaft rotate synchronously. The data measured by the wire rope speed sensor is measured by the small gear of the speed sensor. an...

Abstract

The invention relates to a device for measuring tension of a winch cable and a measuring method thereof, belonging to the technical field of measuring cables. The device for measuring tension of the winch cable comprises a winch drum bracket, a cable drum and a bearing block, the bearing block is arranged on the drum bracket, the cable drum is arranged on the bearing block, and a cable force measuring sensor and a cable speed measuring sensor are arranged on the bearing block. In the method for measuring the device for measuring tension of the winch cable, the step of measuring the tension of the cable comprises the procedures of measuring force of the cable force measuring sensor arranged on the bearing block, measuring data of the cable speed measuring sensor, determining the length of the cable and the position of the cable in the cable drum, calculating the tension of the cable in the position of the cable in the cable drum and determining the tension of the cable. The invention has the advantages of integration of tension measurement and telescopic length measurement of the cable, compact structure, convenience of operation, economy and practicability, high reliability, excellent performance, accurate measurement data and the like.

Description

technical field [0001] The invention belongs to the technical field of wire rope measurement, in particular to a winch wire rope tension measuring device and a measuring method thereof. Background technique [0002] At present, there is a problem of adjustment and positioning of the stinger when large-scale pipe-laying ships are operating in shallow seas. The adjustment and positioning of the stinger generally adopts a heavy-duty adjustment winch, and the design of the adjustment winch and the tension control of the wire rope become the key. Due to the influence of many factors such as the structure, dynamic performance, and working environment of the adjustment winch, as well as the large tension of the wire rope and the difficulty in arranging the measuring points, it is very difficult to accurately measure the tension of the wire rope. [0003] To test the tension of the wire rope of the winch, the common methods are direct weighing measurement method, string vibration f...
