A shaft-disc type take-up and pay-off device for vibration and shock real ship testing

Abstract

The invention provides a shaft disc type line winding and unwinding device used for vibratory impulse shipboard measurement. The shaft disc type line winding and unwinding device is composed of a winding disc, a buckle type line containing shaft disc and a shaft disc supporting frame. The buckle type line containing shaft disc is fixedly connected with the winding disc, and a line passing hole is formed in the center of the buckle type line containing shaft disc. A knob buckle mechanism is mounted in the buckle type line containing shaft disc, and a manual folding rocker is arranged inside the outer side of the buckle type line containing shaft disc in the radial direction. The shaft disc supporting frame is used as a supporting structure of the winding disc and provided with a supporting handle and a parallel-connection shaft hole. Multiple sets of shaft disc type line winding and unwinding devices are expanded in parallel through the shaft holes and knob buckles, and are supported and fixed through auxiliary shaft rods. Through the shaft disc type line winding and unwinding device, reasonable control over the allowance of the two ends of a signal line arranged in any length is achieved, and the trouble that all traditional signal lines are expanded to be arranged can be effectively avoided; meanwhile, the shaft disc type line winding and unwinding device is high in expandability, and multiple shaft disc type line winding and unwinding devices can be combined and fixed in parallel and stored and taken out uniformly; and the structure is reliable, light and rapid.

Description

technical field [0001] The invention relates to a shaft-disk type wire retracting and unwinding device used for vibration shock tests on real ships, which belongs to the retractable arrangement of experimental signal lines and the storage of sensors. Background technique [0002] As an important means of scientific research and exploration, on-site experimental testing plays an important role in promoting academic research. At present, experimental tests often involve the reasonable arrangement of signal lines at multiple measuring points in the equipment structure, which can quickly and accurately collect the characteristic response data of the research object and promote the smooth progress of scientific research. [0003] The current experimental wire collection devices usually use rope bundles or simple coil winding methods. During wiring operations, all signal wires need to be disassembled to install collectors and sensors at both ends of the line, which cannot meet the...

Problems solved by technology

[0003] The current experimental wire collection devices usually use rope bundles or simple coil winding methods. During the wiring operation, all signal wires need to be disassembled to install the collectors and sensors at both ends of the line, which cannot meet the requirements of hundreds of signals in large-scale engineering equipment testing. Requirements for fast and independent placement of lines

There are problems such as heavy workload, long wiring time, messy take-up, and difficulty in quickly collecting short-term working condition data
