Rope head sliding warning device with pressing plate for fixing tail end of steel wire rope

Abstract

The invention discloses a rope head sliding warning device with a pressing plate for fixing the tail end of a steel wire rope, and relates to the technical field of fixing of steel wire ropes for hoists, the rope head sliding warning device comprises an acousto-optic warning assembly, an elastic contact assembly and a jacking switch assembly, the acousto-optic warning assembly is arranged at the upper end of the elastic contact assembly and is in rotary separation type connection with the elastic contact assembly; the jacking switch assembly is movably inserted into the inner end of the elastic contact assembly through an insertion opening in the elastic contact assembly, the elastic contact assembly is fixed to the rope head of the steel wire rope through a buckle, the rope head slides to drive the pull-down switch assembly to slide so that the roller pressing plate can press the elastic contact assembly, and the rope head drives the jacking switch assembly to circumferentially slide. The top pressure switch assembly touches the roller pressing plate, the roller pressing plate presses the lower end of the adjusting pressing sleeve, the threaded top pressure rod is pushed to move inwards along the bottom cover guide seat, and the lower contact of the normally-open elastic wafer is jacked up, so that a worker is reminded to take measures immediately, major accidents caused by rope head slipping are avoided, and equipment and engineering safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel wire rope fixing for hoists, in particular to a rope head sliding warning device for fixing the tail end of a steel wire rope with a pressing plate. Background technique [0002] The winch type hoist is widely used in the water conservancy industry. CN202021482340.X discloses a coastal tidal barrier barrier-type river barrage cable assembly. The tail end of the steel wire rope on the drum is fixed, and the steel wire rope is pressed against the drum wall by a pressure plate. However, whether the connection of the pressure plate is firm or not is directly related to the safety of the project. During the inspection, the staff must pay close attention to whether there is any sign of slipping of the rope head. If there is any sign of slippage, it must be dealt with in time, otherwise it may cause a major accident. However, in order to prevent dust and protect the equipment, the hoist hoist is completely...

Problems solved by technology

[0002] The winch type hoist is widely used in the water conservancy industry. CN202021482340.X discloses a coastal tidal barrier barrier-type river barrage cable assembly. The tail end of the steel wire rope on the drum is fixed, and the steel wire rope is pressed against the drum wall by a pressure plate. However, whether the connection of the pressure plate is firm or not is directly related to the safety of the project operation. During the inspection, the staff should pay close attention to whether there is any sign of slipping of the rope head. If there is any sign of slippage, it must be dealt with in time, otherwise it may cause a major accident

However, in order to prevent dust and protect the equipment, the hoist hoist is completely closed with a cover, so that the staff cannot observe the fixing of the rope head in time; or the light in some areas is dim, and it is difficult for the staff to find out after the rope head slips slightly. , there are potential safety hazards. The hoist hoist of factories and mines also has similar problems when the end of the wire rope is fixed with a pressure plate on the reel. It is urgent for those skilled in the art to design a rope head sliding warning device for fixing the end of the wire rope with a pressure plate.
