The rope end is combined with a taper sleeve type, a self-locking wedge type, a rope clamp type and other forms, wherein the taper sleeve type is the most common form. The Chinese patent with publication number CN202464989U discloses a novel rope end combination device, which comprises a wedge sleeve, a pull rod and a wedge block, wherein the wedge sleeve is in a triangular shape, the wedge sleeve is hollow, one side of the wedge sleeve is provided with a groove, and a positioning pin is arranged on the groove; one end of the wedge sleeve provided with the groove is welded with the pull rod, and a wedge block is embedded in the other end of the wedge sleeve; the pull rod is provided with a fixed seat, the end part of the pull rod is provided with a non-return base, and a spring is connected between the fixed seat and the non-return base, so that the rope head combination is convenient for taking out the wedge block, and the condition that the wedge block runs out of the wedge sleeve is avoided. However, generally, the wedge sleeve adopts a seamless pipe to pass through the processes of blanking, turning, necking, annealing, flattening forming and the like, and stress is generated in the cold work hardening process of necking, so that a phenomenon that cracks are possibly generated for subsequent flattening forming is left, the strength of the wedge sleeve is lower, the probability of elevator operation failure caused by wedge sleeve damage is improved, and the elevator operation safety is lower; and only use the spring as shock attenuation and buffering effect, the effect is general.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide an elevator welding type fag end subassembly that structural strength is high, low in production cost, shock attenuation are effectual.
In order to solve the technical problem, the utility model discloses a pull rod, rope end wedge cover, round pin axle and wedge seat, the one end and the wedge seat of rope end wedge cover cooperate, the other end of rope end wedge cover is connected with the pull rod through the round pin axle, from supreme shock attenuation packing element seat that is equipped with in proper order down on the pull rod, shock attenuation colloid, first spring holder, spring part, second spring holder, gasket and lock nut, wherein rope end wedge cover is equipped with the wire rope body by two wedge plate welded fastening, be equipped with the wire rope on the wedge seat, be equipped with the wire rope on the wire rope body and press from both sides.
As a further improvement, the rope end wedge sleeve comprises a wedge-shaped cavity, the wedge-shaped seat is arranged in the wedge-shaped cavity, the small end of the wedge-shaped seat extends out of the wedge-shaped cavity, the annular groove part matched with the steel wire rope body is arranged on the side of the wedge-shaped seat, and the steel wire rope clamp is arranged at the end part of the steel wire rope body extending out of the wedge-shaped cavity.
As a further improvement, the pull rod is provided with a thread part, wherein the damping rubber cylinder seat and the locking nut are connected with the thread part through threads.
As a further improvement, the damping rubber cylinder seat comprises a placing cavity for placing damping rubber, and the damping rubber is made of nitrile rubber.
The utility model has the advantages that: the rope end wedge sleeve is formed by welding the two wedge plates, so that the problems in the prior art are avoided, and the wedge plate welding forming process is simple, convenient to operate and high in production efficiency. This scheme has increased the structure of shock attenuation colloid, makes the great improvement of shock attenuation and buffering effect.
