Device for measuring thickness of ship plate

Abstract

The invention discloses a device for measuring the thickness of a ship plate. An actuator is installed on a wall-climbing robot, and a pressure sensor and an ultrasonic thickness measurement sensor are installed on the actuator; a control unit is electrically connected with the wall-climbing robot, the pressure sensor, the ultrasonic thickness measurement sensor and the actuator; a coupling agent container is installed on a support, a container pressing head is installed on the upper portion of the coupling agent container, a reset spring is installed between the container pressing head and the coupling agent container, the container pressing head is connected with a smearing head through a hose, one side of the smearing head is connected with a push rod, and the other side of the smearing head is connected with the reset spring; an ejector rod is movably installed in the support, a reset spring is arranged between the ejector rod and the support, and a wedge block, the pressure sensor and the ultrasonic thickness measurement sensor are installed at the lower end of the ejector rod; a cam shaft is connected with a rotary shaft of a stepping motor, and a pressing head cam and an ejector rod cam are installed on the cam shaft in a staggered mode. According to the device for measuring the thickness of the ship plate, thickness measurement points which are distributed more evenly are obtained, thickness measurement efficiency is improved, labor intensity is reduced, the labor cost is reduced, and the working time is shortened.

Description

technical field [0001] The invention relates to a measuring device, in particular to a ship plate thickness measuring device. Background technique [0002] A ship is a complex water engineering structure, which is used in a harsh environment and is subjected to complex external force impacts and seawater corrosion. Among them, seawater corrosion reduces the strength of the hull, shortens the service life of the ship, reduces the navigation performance of the ship, and even causes marine accidents in severe cases. Due to the corrosion hazards of seawater on ship plates, the thickness of ship plates becomes thinner with the increase of service time, and timely detection of ship plate thickness is an important means to ensure safe navigation of ships. [0003] Hull thickness measurement not only enables ship users to better understand the thickness of the hull, but also can more comprehensively grasp the overall strength of the ship. It is an important means to ensure the safe...

Problems solved by technology

[0004] In the existing technology, the thickness measurement of the hull is mainly performed by hand-held ultrasonic thickness gauges. The disadvantages are: the automation of the thickness measurement device is low, and the manual thickness measurement generally has high work intensity, harsh environment, long cycle, and thickness measurement. Disadvantages such as uneven point and low efficiency
