Abstract

The utility model relates to a torsion-prevention wire rope connector, comprising wire rope fixation devices on two ends of the wire rope and a middle torsion release device, wherein the wire rope fixation device is composed of a screwed sleeve, a trapezoidal groove, a U-shaped card, a pressure block and a locking nut; the torsion release device is composed of an end cover, a gasket, a shell, a rotation axle and a bearing. The new, old wire ropes are connected by a torsion-prevention connection device, thus the unsafety hidden trouble of the wire rope due to turnover is prevented when the wire rope passes through the position such as a sheave wheel. The new, old wire ropes are quickly connected and fixed by the clamping function of the trapezoidal groove and the U-shaped card in the screwed sleeve. The wear of the new rope due to torsion of the old rope is prevented from being quickened by the free rotation performance of the bearing in the torsion release device and simultaneously the service life and safety of the wire rope are increased.

Description

The anti-wire rope connector that reverses

Technical field

The utility model is relevant with wire-rope connecting device, especially a kind of technological scheme that is used for preventing reversing the wire rope connector.

Background technique

The intensity of wire rope is high, 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, carry to change to wait like wire rope and also can make wire rope receive torsion.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 through wire line shoe.If old rope produces and reverses the upset that must also can cause rope cramp, let new rope also receive torsion.So not only can be in changing the rope process as two rope joints cause trouble during through head sheave etc., also can let and aggravate wearing and tearing because of the existence of torsion in the use afterwards of new rope, influence working life.Therefore; Design and a kind ofly anti-reverse the wire rope connector, be used for the connection between the new and old wire rope, and receive torsion and when reversing when old rope; The releasing device that reverses through on this connection set avoids torque transfer to arrive new rope; 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 utility model provides a kind of anti-wire rope connector that reverses, and connects the two ends wire rope and reaches the anti-requirement of reversing to adapt to.

A kind ofly anti-reverse the wire rope connector, comprise that wire rope fixing device reverses releasing device through being threaded;

Said wire rope fixing device is made up of screw shell, dovetail groove, U type card, briquetting, 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 said releasing device that reverses is made up of end cap, pad, housing, rotating shaft, angular contact bearing and thrust ball bearing, is with angular contact bearing and thrust ball bearing in the rotating shaft, and in the housing of packing into, housing opening is sealed by end cap after covering pad.

In technique scheme, said screw shell one end is provided with internal thread, and the other end pipe shaft is semi-circular structure, and on the semicircle tube wall, is provided with four through holes, and said through hole both sides are evenly equipped with three dovetail grooves; Said U type cartoon is crossed the through hole on the screw shell tube wall and is inserted respectively between the space of three dovetail grooves; And be provided with screw thread at its two foot, through being screwed in the locking nut locking U type card behind the briquetting with identical four-way hole; Said end cap is provided with the outside thread cylindrical body, and corresponding with the internal thread of screw shell one end; Its inside of said housing 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; Its lower end of said rotating shaft is provided with screw thread, and links to each other with another wire-rope connecting device.

The utility model applies opposite force and with the wire rope clamping, has realized the simple and rapid connection of wire rope fixing wire rope through dovetail groove in the threaded sleeve and U type card; Pass through connection set; The wire rope two ends just have been separately fixed on the shell and rotating shaft that reverses releasing device; Again through freely the rolling of bearing between shell and rotating shaft, possibly appear at reversing on the wire rope body and transfer to and reverse on the releasing device, it can not reversed because of self wear and tear, damage wire rope; Thereby protected wire rope, improved wire rope working life greatly.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the embodiment of the utility model is made further explain:

Shown in Fig. 1-4, enforcement the utility model is a kind of to be prevented reversing the wire rope connector, comprises wire rope fixing device and reverses releasing device two-part formation.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 up 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; Have the briquetting of identical four through holes corresponding place on the threaded sleeve outer wall, after the foot of two U type cards penetrates from the threaded pipe inwall, 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 through scyewed joint and the end cap that reverses releasing device again.End cap is loaded onto through 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 through scyewed joint.

When this device carries out the wire rope connection: locking nut 5 is unscrewed; Pull out U type card 3; Put into 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, through dwindle between dovetail groove 2 and the U type card 3 distance and exert pressure on the wire rope fix on wire rope.

During the work of this device, through 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.
