Abstract

The invention relates to an anti-torsion connection device of a steel wire rope, comprising steel wire rope fixing devices on both ends and a torsion release device in the middle; each steel wire rope fixing device comprises a threaded sleeve, a trapezoidal groove, a U-shaped clip, a pressure block and a locking nut; and the torsion release device comprises an end cover, a gasket, a shell body, a rotating shaft and a bearing. The anti-torsion connection device is adopted for connecting steel wire ropes, so that unsafe hidden hazards caused by the steel wire ropes when passing through a head sheave and the like due to overturn, simultaneously the quick connection and fixation of an old rope and a new rope are realized through a clamping function between the trapezoidal groove and the U-shaped clip in the threaded sleeve, the new rope is prevented from more serious wear caused by torsion due to the torsion of the old rope through the free rotation of the bearing in the torsion release device, and the service life and the safety of the steel wire ropes are improved.

Description

A kind of anti-torsion connection device of steel wire rope

Technical field

The present invention is relevant with wire-rope connecting device, and is especially a kind of for the anti-technological scheme of reversing Quick Connect Kit of wire rope.

Background technique

The intensity of wire rope is high, from heavy and light, stable working, be difficult for suddenly whole root fracture, reliable operation is widely applied in material carrying machine, is very widely flexible structure of a kind of application.Wire rope is under the tension force effect, and the spiral key element in it interacts and produces internal force, and these internal force can be decomposed into the axial thrust load of wirerope axis line parallel with perpendicular to the radial component of wire rope axis, and radial component just makes rope strand or wire rope produce to reverse; Simultaneously, externally during conditional instability, carrying changes to wait and also can make wire rope be subject to torsion such as wire rope.Wire rope torsional deflection occurs under this internal force or external factor impact; to wear and tear, damage wire rope; cause wire rope broken lot and fracture of wire to occur when serious, greatly impact is known clearly the working life of wire rope, simultaneously protection safety in production and life has been caused safely great threat.At present, change when rope at headframe, employing be the method for the new rope of old rope traction, and being connected normally between old rope and the new rope fixed two ropes by wire line shoe.If old rope produces and reverses the upset that must also can cause rope cramp, allow new rope also be subject to torsion.So not only can be in changing the rope process as two rope joints cause trouble during by head sheave etc., also can allow in the use afterwards of new rope because the existence of torsion and unstable wear affects working life.

Therefore, invent a kind of anti-torsion connection device of steel wire rope, be used for the connection between the new and old wire rope, and when old rope is subject to torsion and reverses, avoid torque transfer to arrive new rope by the torsional release device on this connection set, thereby avoid above situation to occur, prolong the working life of wire rope, for safety in production and personal safety provide guarantee.

Summary of the invention

The invention provides a kind of anti-torsion connection device of steel wire rope, connect the two ends wire rope and reach the anti-requirement of reversing to adapt to.

To achieve these goals, institute of the present invention Adopts measure is a kind of anti-torsion connection device of steel wire rope, comprises that wire rope fixing device is connected with torsional release device;

Described wire rope fixing device is to be made of screw shell, dovetail groove, U-shaped card, briquetting and locking nut, dovetail groove in screw shell, between be furnished with U-shaped card, U-shaped card is locked by locking nut after passing the tube wall of briquetting and screw shell;

Described torsional release device is to be made of end cap, pad, housing, rotating shaft, angular contact bearing and thrust ball bearing, and cover has angular contact bearing and thrust ball bearing in the rotating shaft, and in the housing of packing into, housing opening is equipped with pad and is sealed by end cap.

In technique scheme, described screw shell is that an end is provided with internal thread, and the other end pipe shaft is semi-circular structure, and is provided with four through holes at the semicircle tube wall, and described through hole both sides are evenly equipped with three dovetail grooves; Described U-shaped card is to insert respectively between the space of three dovetail grooves by the through hole on the screw shell tube wall; And be provided with screw thread at its two foot, by being screwed in the locking nut behind the briquetting with identical four-way hole, lock U-shaped card; Described end cap is provided with the outside thread cylindrical body, and corresponding with the internal thread of screw shell one end; Described housing is that its inside is equipped with rotating shaft, and both sides are separately installed with angular contact bearing and thrust ball bearing between its greatest axis, and each bearing matches with inner walls again; Described rotating shaft is that its lower end is provided with screw thread, and links to each other with another wire-rope connecting device.

A kind of anti-torsion connection device of steel wire rope of the present invention by dovetail groove in the threaded sleeve and U-shaped card, applies opposite force and with the wire rope clamping, has realized simply and fast being connected and fixed wire rope wire rope; Pass through connection set; the wire rope two ends just have been separately fixed on the shell and rotating shaft of torsional release device; again by shell and the Free-rolling that turns bearing; may appear at reversing on the wire rope body has transferred on the torsional release device; make it can not wear and tear and damage wire rope because self reversing; thereby protected wire rope, greatly improved the working life of wire rope.

Embodiment

Below in conjunction with accompanying drawing and instantiation the specific embodiment of the present invention is further detailed:

Shown in Fig. 1-4, implement a kind of anti-torsion connection device of steel wire rope, comprise that wire rope fixing device and torsional release device two-part consist of.Wherein, wire rope fixing device is comprised of threaded sleeve 1, dovetail groove 2, U-shaped card 3, briquetting 4, locking nut 5; Torsional release device is made of end cap 6, pad 7, housing 8, rotating shaft 9, angular contact bearing 10 and thrust ball bearing 11.Three dovetail grooves evenly distribute and are welded on the end inwall of threaded sleeve, and the tube wall between each dovetail groove is drilled with four through holes, briquetting correspondence with identical four through holes and is placed on the threaded sleeve outer wall, after the foot of two U-shaped cards penetrates from the threaded pipe inwall, pass through the hole, pass from the back side of briquetting, and cover has locking nut on the screw thread of U-shaped card base end.Threaded sleeve links together by the end cap of scyewed joint and torsional release device again.End cap is loaded onto by bolt group and housing and shim pack.In enclosure interior angular contact bearing and thrust ball bearing are installed, have assigned rotating shaft between two bearings, the threaded end of rotating shaft and another rope fixing device link together by scyewed joint.

When this device carries out the wire rope connection: locking nut 5 is unscrewed, pull out U-shaped card 3, insert wire rope in dovetail groove 2 in threaded sleeve 1 and the space between the U-shaped card 3, final force is tightened locking nut 5, fixes wire rope by dwindling the distance between dovetail groove 2 and the U-shaped card 3 and exerting pressure at wire rope.

During the work of this device, by the bearing in the housing 6, the two ends wire rope can freely rotate, thereby discharges moment of torsion, can not produce warping stress and strain, has avoided wire rope therefore to suffer damage and weares and teares, and has prolonged the working life of wire rope.
