Abstract

The invention discloses an automatic measurement pin for tension, belongs to a tension sensor, and is used for solving the defects of the prior art that the measurement of the stress conditions of a rope is not accurate enough when a ship berths and the imported instrument is expensive and is not convenient to use. The automatic measurement pin for tension comprises a shaft body, wherein an electric signal amplifier, a lubrication oil groove and a lubrication oil cup are arranged in the shaft body; two stress sheets are arranged on a surface layer; a cable sealing joint and a signal cable outgoing end are arranged on the outer wall; the signal cable outgoing end is arranged on the cable sealing joint; the electric signal amplifier, the stress sheets and the cable sealing joint are connected through signal wires; the lubrication oil cup is led to the outer part of the shaft body through the lubrication oil groove; each stress sheet is provided with a screwed plug and coated with sealant; a shaft end sealing cover is arranged at one end of the shaft body; and a sealing ring and an insulating base plate are arranged in the shaft body between the shaft end sealing cover and the electric signal amplifier. The automatic measurement pin for tension disclosed by the invention is mainly used for measuring the stress conditions of the ship berthing in a dock.

Description

technical field [0001] The invention belongs to a tension sensor, in particular to a tension automatic measuring pin. Background technique [0002] After the ship docks at the dock, the cable on the ship must be tied to the release hook of the dock, and it is necessary to know the force of the cable accurately and stably to ensure the safety of the ship docking. Due to the limitation of technical level in China, it is impossible to accurately measure the force of the cable. Currently used monitoring pins are all imported, expensive, and inconvenient after-sales service, which brings great limitations to the use of tension monitoring pins. At present, there is no tension measuring device that can accurately measure the force of the cable when the ship is docked, and is easy to operate and widely used. Contents of the invention [0003] In order to solve the defects in the prior art that the measurement of the force on the cable is not accurate enough when the ship is dock...
