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

The anti-connection set that reverses of a kind of wire rope

Technical field

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

Background technique

The intensity height of wire rope, from heavy and light, stable working, be difficult for whole suddenly root fracture, reliable operation is widely applied in materials handling machinery, is the flexible very widely 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 subjected to torsion as wire rope.Wire rope torsional deflection occurs under this internal force or external factor influence; to wear and tear, damage wire rope; cause wire rope broken lot and fracture of wire to occur when serious, influence is greatly known clearly the working life of wire rope, simultaneously protection safety in production and life safety has been caused 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 subjected 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 and aggravate wearing and tearing because of the existence of torsion in the use afterwards of new rope, influence working life.

Therefore, invent the anti-connection set that reverses of a kind of wire rope, be used for the connection between the new and old wire rope, and when old rope is subjected to torsion and reverses, avoid torque transfer to arrive new rope by the releasing device that reverses 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 the anti-connection set that reverses of a kind of wire rope, connect the two ends wire rope and reach the anti-requirement of reversing to adapt to.

To achieve these goals, to be that a kind of wire rope is anti-reverse connection set in the measure that the present invention taked, and comprises that wire rope fixing device is connected with to reverse releasing device;

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

The described releasing device that reverses is to be made of end cap, pad, housing, rotating shaft, angular contact bearing and thrust ball bearing, be with 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 on the semicircle tube wall, and described through hole both sides are evenly equipped with three dovetail grooves; Described U type 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 locking U type card behind the briquetting with identical four-way hole; 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 wire rope of the present invention is anti-to reverse connection set, by dovetail groove in the threaded sleeve and U type card, wire rope is applied opposite force and wire rope is clamped, and has realized the simple and rapid of wire rope is connected and fixed; Pass through connection set; the wire rope two ends just have been separately fixed on the shell and rotating shaft that reverses releasing device; freely rolling by bearing between shell and rotating shaft again; may appear at reversing on the wire rope body has transferred to and has reversed on the releasing device; make it can not wear and tear and damage wire rope because of self reversing; thereby protected wire rope, improved the working life of wire rope greatly.

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 wire rope and prevent reversing connection set, comprise wire rope fixing device and reverse releasing device two-part constituting.Wherein, wire rope fixing device is made up of threaded sleeve 1, dovetail groove 2, U type card 3, briquetting 4, locking nut 5; Reversing releasing 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 on the tube wall between each dovetail groove, be 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 type cards penetrates from the threaded pipe inwall, pass through the hole, pass from the back side of briquetting, and be with locking nut on the screw thread of U type card base end.Threaded sleeve links together by scyewed joint and the end cap that reverses releasing 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 type card 3, insert wire rope in the space between dovetail groove 2 in threaded sleeve 1 and the U type card 3, final force is tightened locking nut 5, fixes wire rope by dwindling the distance between dovetail groove 2 and the U type card 3 and exerting pressure on wire rope.

During the work of this device, by the bearing in the housing 6, the two ends wire rope can freely rotate, thereby the release moment of torsion can not produce warping stress and strain, avoided wire rope so and suffer damage and wear and tear, prolonged the working life of wire rope.
