Abstract

The utility model provides a tail end wedging type steel wire rope fixing device, which is characterized in that two semicircular conical sleeves are spliced to form an integral conical sleeve, and the integral conical sleeve is sleeved in the conical sleeve with a conical through hole inside to form a typical wedging matching structure. In the in-service use, when wire rope bears the pulling force, the conical sleeve behind the concatenation removes to the little end direction along the bell mouth of conical sleeve under the pulling effect, under the cooperation restriction that the bell mouth narrows gradually, two semicircle conical sleeves are forced to closely laminate wire rope core and fag end gradually to realize "pull more tight" from the tight effect of auto-lock clamp more, effectively prevent wire rope slippage, promote the fastness and the safety in utilization of connection. Meanwhile, a through hole is formed in the middle of the semi-conical sleeve in the device and used for accommodating a main rope core of the steel wire rope, a plurality of inwards-sunken steel wire rope strand fixing holes are formed in the side edges of the semi-conical sleeve, and outer layer strands of the steel wire rope can be respectively embedded and fixed to play roles in accurate guiding and component force.

Description

Terminal wedging type steel wire rope fixing device Technical Field The utility model relates to the technical field of steel wire rope fixing devices, in particular to a tail end wedging type steel wire rope fixing device. Background The steel wire rope is used as a high-strength flexible connecting piece and is widely applied to the engineering fields of hoisting, transportation, mines and the like. In the use process, the fixing and the connection of the steel wire rope are key links for ensuring the operation safety and the force transmission reliability. Especially in the aspect of fixing the end part of the steel wire rope, if the fixing mode is unstable, the stress is uneven or the structure is unreasonable, the steel wire rope is easy to slip, the rope strand is broken or the fixing part is fatigued and damaged, and then the safety accident is caused. The current common fixing mode of the end part of the steel wire rope comprises aluminum sleeve crimping fixing, wedge clamping type connection, sleeve pouring type anchoring and the like. The wedging type fixing structure is widely applied due to the advantages of simple assembly, high bearing capacity, convenient disassembly and the like. The prior wedging type fixing device has the defects that firstly, part of the structure is fixed only by virtue of contact friction between the whole steel wire rope and the wedge sleeve, the rope core and the rope strand are not limited respectively, uneven stress is caused, looseness is easy to occur, secondly, the wedge type clamping structure is designed in an integrated mode, the installation and the operation are inconvenient, the assembly precision and the safety are difficult to ensure especially in a site construction environment, thirdly, certain structures lack necessary anti-abrasion design, and the problems of clamp deformation, failure and the like are easy to occur under long-term use or heavy-load working conditions. Therefore, it is necessary to provide a terminal wedging type steel wire rope fixing device which has a more reasonable structure, a more reliable clamping effect, a longer service life and is convenient for quick installation. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the tail end wedging type steel wire rope fixing device, which effectively solves the problems of poor clamping effect, complex installation and the like of part of traditional steel wire rope fixing devices. The utility model provides a fixed wire rope device of terminal wedging, it contains two semicircle taper sleeves and a taper sleeve, two the middle part of semicircle taper sleeve all is provided with a through hole, two the side of semicircle taper sleeve all inwards is sunken to be provided with a plurality of wire rope strand fixed orifices, two the concatenation of semicircle taper sleeve sets up to a taper sleeve and overlaps to in the taper sleeve, the inside toper perforation that is provided with of taper sleeve, the minimum aperture of toper perforation is less than two the biggest external diameter of taper sleeve after the concatenation of semicircle taper sleeve sets up, the minimum aperture of toper perforation is greater than two the biggest external diameter of taper sleeve after the concatenation of semicircle taper sleeve sets up. Preferably, a plurality of protrusions are arranged on the inner side wall of the through hole and the outer side wall of the steel wire rope strand fixing hole in an outward protruding mode. Preferably, an extrusion-resistant layer and a wear-resistant layer are sequentially arranged on the outer side wall of the semi-conical sleeve and the inner side wall of the conical sleeve from inside to outside.
