Abstract

The utility model relates to a kind of wire rope anti-rotation joint, and it is characterized in that, upper ear plate is welded on plectane, and plectane welds with shell; One end of described lower ear plate is threaded with round nut, is screwed; Described bearing bore diameter and lower ear plate are connected, and bearing outside diameter and internal diameter of outer cover are connected; Described round nut one end withstands on bearing inner sleeve; Described cover one end withstands on bearing outside, and the other end withstands on down and covers; Described lower cover and shell are bolted together; Described lower ear plate and upper ear plate can rotate freely relative to overcoat by bearing inner sleeve.The beneficial effects of the utility model are: the rotation solving wire rope is turned round and jib structure local pressure problems of too, improve connection rationality, solve again and bring the stressed bad problem causing the reduction of its intensity and working life to shorten of wire rope because wire rope rotates, eliminate potential safety hazard.

Description

Wire rope anti-rotation joint

Technical field

The utility model relates to a kind of wire rope and the arm support connection device in hoisting and hanging field, particularly a kind of wire rope anti-rotation joint.

Background technique

At present, during the work of the suspension hook such as truck crane, crawler crane even number multiplying power, the means of fixation of steel wire rope head end (wherein one end) is generally directly adopt the otic placode on the fast joint type socket at cable wire end place and jib head to be fixed by bearing pin.This Placement also exists defect:

1) in use owing to easily causing wire rope to be turned round aloft when suspension hook rotates, have impact on intensity and the working life of wire rope, there is potential safety hazard.

2) in order to improve performance and security consideration, usual way selects anti-rotating wire rope, but the price of the cost ratio ordinary steel rope of anti-rotating wire rope wants much expensive, and cost is high.

Summary of the invention

The technical problem that the utility model solves is to provide a kind of wire rope anti-rotation joint, under the prerequisite of anti-rotating wire rope not using high cost, the articulation issues of wire rope and jib can not only be solved very well, wire rope rotating can be solved again and bring the stressed bad problem causing the reduction of its intensity and working life to shorten of wire rope, eliminate potential safety hazard.

In order to achieve the above object, the utility model realizes by the following technical solutions:

Wire rope anti-rotation joint, comprises upper ear plate, plectane, screw, round nut, bearing, lubricating cup, shell, cover, lower cover, lower ear plate, it is characterized in that, described upper ear plate is welded on plectane, and plectane welds with shell; One end of described lower ear plate is threaded with round nut, is screwed; Described bearing bore diameter and lower ear plate are connected, and bearing outside diameter and internal diameter of outer cover are connected; Described round nut one end withstands on bearing inner sleeve; Described cover one end withstands on bearing outside, and the other end withstands on down and covers; Described lower cover and shell are bolted together.

Described lower ear plate and upper ear plate can rotate freely relative to overcoat by bearing inner sleeve.

Described shell is provided with lubricating cup.

Compared with prior art, the beneficial effects of the utility model are:

1) this model utility is adopted, under the prerequisite of anti-rotating wire rope not using high cost, both the rotation having solved wire rope is turned round and jib structure local pressure problems of too, improve connection rationality, solve again and bring the stressed bad problem causing the reduction of its intensity and working life to shorten of wire rope because wire rope rotates, eliminate potential safety hazard;

2) structure is simple, is easy to make, easy to install, with low cost.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

See Fig. 1, the utility model relates to a kind of wire rope anti-rotation joint, comprise upper ear plate 1, plectane 2, screw 3, round nut 4, bearing 5, lubricating cup 6, shell 7, cover 8, lower cover 9, lower ear plate 10, described upper ear plate 1 is welded on plectane 2, plectane 2 welds with shell 7, and such upper ear plate 1 is just integrated with 7 one-tenth, shell; One end of described lower ear plate 10 is threaded with round nut 4, fixes with screw 3, and prevent round nut 4 from loosening, bearing 5 internal diameter and lower ear plate 10 are connected, and such screw 3, round nut 4, bearing 5 inner sleeve are just integrated with lower ear plate 10 one-tenth; The minor diameter fit of bearing 5 external diameter and shell 7 connects as one; Described round nut 4 one end withstands in bearing 5 and puts; Described cover 8 one end withstands on outside bearing 5 and puts, and the other end withstands on lower cover 9; Described shell 7 is bolted together with lower cover 9, and such upper ear plate 1, plectane 2, shell 7, bearing 5 overcoat, lower cover 9 just become to be integrated.

Described lower ear plate 9 can rotate freely relative to overcoat by bearing 5 inner sleeve with upper ear plate 1.

Described shell 7 is provided with lubricating cup 6, with thinking bearing 5 charging-up lubricant oil.

In a state of use, described upper ear plate 1 is coupled together by the otic placode on bearing pin and crane arm support head this model utility wire rope anti-rotation joint; In like manner, described lower ear plate 10 is coupled together by the fast joint type socket of bearing pin and wire rope end, utilize the feature that rolling bearing 5 inner ring can freely rotate relative to outer ring, realize the upper ear plate 1 rotatable function of lower ear plate 10 relatively, prevent wire rope to be subject to turn round the intensity and working life affecting wire rope, eliminate safe hidden trouble.
