Abstract
The utility model discloses a rope end connecting structure of an elevator steel wire rope. When rope ends of the elevator steel wire rope are connected, one end of the steel wire rope penetrates from a cone-shaped end part of a cone round sleeved pipe to a pipe cavity of the cone round sleeved pipe and then penetrates out a round end part of the cone round sleeved pipe. A penetrated rope end part is divided into a rope core and multiple steel wire rope shared splits, and the multiple steel wire rope shared splits are respectively pressed into multiple grooves of the round end part of the cone round sleeved pipe. A thread cap is in screw-thread fit on the round end part of the cone round sleeved pipe and clamps the multiple steel wire rope shared splits. The cone-shaped end part of the cone round sleeved pipe is in screw-thread fit on a thread punched hole of a fastening wedge block. Due to the fact that multiple gaps are arranged on the cone-shaped end part, the cone-shaped end part of the cone round sleeved pipe can be reduced on the thread punched hole of the fastening wedge block, thus the rope ends of the steel wire rope inside the pipe cavity of the cone round sleeved pipe can be clamped. The length of the occupied steel wire rope of the rope end connecting structure of the steel wire rope is short, thus the length of the steel wire rope which can be dragged and guided and used effectively is long. The rope end connecting structure of the elevator steel wire rope is small in volume, and the occupied well space is small.

during concrete enforcement, described cone circular sleeve is milled with the plane be oppositely arranged on the outside face at the position between conical end and circular end, also all is milled with the plane be oppositely arranged on the outer surface of described thread cap, described fastening voussoir.
utilization due to technique scheme, the utility model compared with prior art has following advantages: in this rope end of elevator steel wire rope connection structure, coordinating of threaded perforations by thread cap and the conical end that coordinates, bores circular sleeve and the fastening voussoir of the circular end of cone circular sleeve, realized being fastenedly connected of rope end of elevator steel wire rope, this length that is fastenedly connected shared wire rope end is shorter, thereby the length that can make the steel rope that effective traction used is longer, and this structural volume be fastenedly connected is little, shared hoistway space is little.
The accompanying drawing explanation
accompanying drawing 1 is looked cross-sectional schematic for master of the present utility model;
accompanying drawing 2 is schematic top plan view of the present utility model.
The specific embodiment
further set forth structure of the present utility model below in conjunction with accompanying drawing.
shown in Fig. 1-2, a kind of rope end of elevator steel wire rope connection structure, comprise fastening voussoir 1, cone circular sleeve 2, thread cap 4, have and be at least partly cylindrical-conical threaded perforations on fastening voussoir 1, in the tube chamber of cone circular sleeve 2, for wire rope end 3, pass, it is conical that one end of this cone circular sleeve 2 is, the other end is rounded, be provided with outside thread on the conical end 21 of cone circular sleeve 2 and the outer surface of circular end 22, the tapering of the conical end 21 of cone circular sleeve 2 is consistent with the tapering of the threaded perforations of fastening voussoir 1, like this conical end 21 of cone circular sleeve 2 can screw thread fit in the threaded perforations of fastening voussoir 1.The circular end 22 of cone circular sleeve 2 can screw thread fit in thread cap 4.Offer a plurality of breach that are connected with the tube chamber of this cone circular sleeve 2 on the outer surface of the conical end 21 of cone circular sleeve 2, the length direction of this breach extends along the length direction of cone circular sleeve 2 tube chambers, and a plurality of breach are spaced along the circumferential direction of boring circular sleeve 2, a plurality of breach are set, make the conical end 21 of cone circular sleeve 2 there is certain contractibility when stressed, that is to say, conical end 21 screws thread fit of cone circular sleeve 2 can tighten in the threaded perforations of fastening voussoir 1 time, thereby compress the wire rope end 3 in cone circular sleeve 2 tube chambers.In Fig. 1, offer a plurality of grooves 23 on the outer surface of the circular end 22 of cone circular sleeve 2, the plurality of groove 23 also is spaced along the circumferential direction of cone circular sleeve 2, passing through fastening voussoir 1, cone circular sleeve 2, when thread cap 4 connects rope end of elevator steel wire rope 3, this wire rope end 3 penetrates the tube chamber of this cone circular sleeve 2 from the conical end 21 of cone circular sleeve 2, and pass from the circular end 22 of this cone circular sleeve 2, the end passed partly is dispersed into wire rope core and a plurality of steel rope share split 31, the plurality of steel rope share split 31 is pressed into respectively in a plurality of grooves 23 of the circular end 22 of boring circular sleeve 2, thread cap 4 screws thread fit are on the circular end 22 of cone circular sleeve 2, and compression is lived a plurality of steel rope share splits 31, the center of thread cap 4 has perforation 41, dispersed wire rope core passes the central hole 41 of thread cap 4, conical end 21 screws thread fit of cone circular sleeve 2 are in the threaded perforations of fastening voussoir 1, on conical end 21 due to the setting of a plurality of breach, make the conical end 21 of cone circular sleeve 2 tighten in the threaded perforations of fastening voussoir 1, thereby compress the wire rope end 3 in cone circular sleeve 2 tube chambers.Coordinating of threaded perforations by thread cap 4 and the conical end that coordinates, bores circular sleeve 2 21 and the fastening voussoir 1 of the circular end 22 of cone circular sleeve 2, realized being fastenedly connected of rope end of elevator steel wire rope, this length that is fastenedly connected shared wire rope end is shorter, thereby the length that can make the steel rope that effective traction used is longer, and this structural volume be fastenedly connected is little, shared hoistway space is little.After connecting rope end of elevator steel wire rope, fastening voussoir 1 is fixed on rope hitch plate, realize wire rope end being fixedly installed in elevator hoistways.
for the convenient wrench binding thread connects, cone circular sleeve 2 is milled with the plane be oppositely arranged on the outside face at the position between conical end 21 and circular end 22, be convenient to the spanner clamping location, also be milled with the plane 42 be oppositely arranged on the outer surface of thread cap 4, also be milled with the plane 11 be oppositely arranged on the outer surface of fastening voussoir 1, be convenient to equally the spanner clamping location, as shown in Figure 2, thereby make relative turn thread cap with cone circular sleeve, fastening voussoir and bore the easy to operate of circular sleeve.
sum up, when the rope end of elevator steel wire rope connection structure of application this patent, first wire rope end is passed to fastening voussoir, then wire rope end is passed to the cone circular sleeve, penetrate from conical end, pass from circular end.Then the steel cord ends passed is divided and breaks up, each minute strand steel wire rope is pressed into to the groove of boring circular sleeve successively.The wire rope core that then will break up out passes thread cap, and thread cap is fastened on the circular end of cone circular sleeve, compresses each share split of steel rope simultaneously.Finally that fastening voussoir is fastening with the conical end of cone circular sleeve, because the conical end of cone circular sleeve is jagged, in fastening process, can shrink, thereby compress wire rope end.This rope end of elevator steel wire rope connection structure is simple, easy for installation; Volume is little, saves hoistway space; During repair and maintenance, be threaded to make and regulate rope capacity conveniently.
