Abstract

The invention discloses a hoisting chain tension detection machine, which comprises a machine frame body, a distance regulating assembly and a tension assembly, wherein the distance regulation assembly comprises regulating rods, lead screws and moving rods; the regulating rods are rotationally connected with the two ends of the machine frame body; the lead screws are rotationally connected onto the two sides of the machine frame body; the lower ends of the moving rods are connected with the lead screws through screw threads; the upper ends of the moving rods extend out of the machine frame body; worm rod sections are fixedly connected into positions, corresponding to the lead screws, on the regulating rods; the rotating directions of the adjacent worm rod sections are opposite; worm wheelsections engaged with the worm rod sections are also respectively and fixedly connected in positions, corresponding to the worm rod sections, of the lead screw. In the use process, the two ends of a hoisting chain are respectively fixed with the tension assembly; the middle of a hoisting chain machine bypasses trough the upper ends of the moving rods in an S-shaped staggering way; next, the regulating rods rotate; the adjacent lead screws are driven to rotate in opposite directions, so that the adjacent moving rods are driven to move in opposite directions; the hoisting chain is further drivento move and is in Z-shaped arrangement on the machine frame body; next, the tension assembly is started for tension test; the structure is compact; the size is smaller; the use space is saved.

Description

technical field [0001] The invention relates to the field of chain tension, in particular to a lifting chain tension detection machine. Background technique [0002] The lifting chain is an essential and important pick-up device for the crane. It plays an important role in improving the operating efficiency of the crane and expanding the operating range of the crane. In the testing process of lifting chains, the pull test is an indispensable and important link. The pulling force used in the pulling test of most existing lifting chains is generally at least that of the working environment. more than double. [0003] The existing Chinese patent whose authorized announcement number is CN202938951U can be referred to. The lifting chain tension detection device includes a fixed platform, a hydraulic cylinder and a chuck. The lower end of the fixed platform is provided with a plurality of support columns. A support column is provided between adjacent support columns. One end of ...
