Special hanger for loading and unloading steel rails

Abstract

The invention discloses a special hanger for loading and unloading steel rails, aiming at overcoming the defects of increase of loading-unloading cost, low loading-unloading efficiency and unsafety caused by damage and scrap of steel ropes as the steel rope is buckled at two ends of a steel rail for lifting and unloading conveying in the prior art. In a vertical supporting frame, a floating support is provided with lifting lugs which are movably connected with the upper ends of two pull rods which are eudipleural, the lower ends of both pull rods are movably connected with two rotating tongues which are oppositely arranged, and the rotating tongues are respectively and oppositely supported on the supporting frame; the supporting frame and the rotating tongues are provided with a locking device which can enable two tongue tips of the rotating tongues to oppositely rest on the horizontal position when the lifting lugs are lifted and to rest on the vertical position when the two tongue tips are put down. As the supporting frame is provided with the locking device which can enable the tongue tips of both rotating tongues to oppositely rest on the horizontal position and the vertical position, the tongue tips of both rotating tongue tips can be hooked and unhooked at the lower edge of the rail surface of a steel rail, thereby the steel rail down can be lifted and put down. The special hanger for loading and unloading steel rails has the advantages of no need of steel rope buckles, high efficiency, no consumption of raw materials, low loading and unloading cost, simple operation and safe and reliable use.

Description

technical field [0001] The invention belongs to a sling, in particular to a sling specially used for loading and unloading steel rails. Background technique [0002] The rail transportation volume on the port wharf is very large all year round, and the loading and unloading work is very busy. The hoisting operation mode of existing loading and unloading rail is, uses steel wire rope buckle pocket at the two ends of rail, hangs steel wire rope buckle hoisting with crane pocket. Because in the process of hanging, there will be severe friction between the edges and corners of the rail and the wire rope buckle, resulting in a large amount of scrapping of the steel wire rope buckle due to serious friction damage. According to statistics in lifting practice, about 12-16 steel wire rope buckles will be scrapped for every thousand tons of rails loaded and unloaded, which will increase the loading and unloading costs of the enterprise and greatly affect the economic benefits; at the...

Problems solved by technology

[0003] The technical problem to be solved by the invention is to overcome the disadvantages of the prior art that the steel wire rope is buckled at both ends of the rail for hoisting, loading and unloading transportation, causing the wire rope to be damaged and scrapped, increasing the loading and unloading cost, and the loading and unloading efficiency is low and unsafe, and to provide a special crane for rail loading and unloading.
