Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for heavy material transportation, and particularly to an anti-loosening device for a steel wire rope fixing rod of a double-leg type suspended unloading platform. Background Art

[0002] As is well known, a suspended unloading platform is a device used for placing and lifting heavy materials to improve the working efficiency of heavy materials during processing or overall packing. In the existing suspended unloading platform, one end of the steel wire rope is generally connected to the unloading platform during work, and the other end of the steel wire rope passes through a reserved hole in a shear wall or beam at a relevant position and is hung on a fixing rod behind the reserved hole to bear force. Generally, the steel wire rope fixing rod required for work is fastened to the shear wall or beam surface by bearing the force of the steel wire rope. When the existing anti-loosening device for the steel wire rope fixing rod of the double-leg type suspended unloading platform is in use, the staff places the materials to be lifted and transported above the unloading platform and directly lifts the unloading platform. However, it is found in the use of the existing anti-loosening device for the steel wire rope fixing rod of the double-leg type suspended unloading platform that during the process of hoisting materials and pulling the unloading platform, the steel wire rope will cause the fixing rod at the rear end to loosen and even flip and slide together. When the pulling is completed, the unloading platform will suddenly fall back, causing a great impact on the steel wire rope and the fixing rod. In the long run, it is extremely easy to cause wear of the steel wire rope and the fixing rod, and even premature scrapping due to fatigue and shear failure caused by the impact force before reaching the service life. This not only wastes materials but also easily leads to high-drop safety accidents of the unloading platform, resulting in low working reliability. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides an anti-loosening device for a steel wire rope fixing rod of a double-leg type suspended unloading platform, which can effectively fix the position of the steel wire rope fixing rod, prevent the steel wire rope fixing rod from flipping and sliding, buffer the impact caused by the fall of the unloading platform to the steel wire rope and the fixing rod when the pulling is completed, effectively extend the working life of the steel wire rope fixing rod during work, reduce the probability of high-drop safety accidents of the unloading platform, and thus improve the use reliability.
