Abstract

The invention provides a cable elbow-type joint quadrangle hoop dismounting device, and belongs to the technical field of power transmission and distribution engineering. The cable elbow-type joint quadrangle hoop dismounting device is composed of a quadrangle hoop which is formed by four segments via hinging, a set of bolt and two nipping nails. The quadrangle hoop closely embraces an elbow-type joint clinging equipment segment; and the two nipping nails, of which one is arranged on the upper part and the other is arranged on the lower part, abut against equipment to jack up the quadrangle hoop which embraces an elbow-type joint so that the elbow-type joint is pulled out of the equipment. The cable elbow-type joint quadrangle hoop dismounting device is simple and convenient without damage to the elbow-type joint, and thus the cable elbow-type joint quadrangle hoop dismounting device is used for the power transmission and distribution engineering.

Description

Cable elbow-shaped joint four closes hoop remover

Technical field power transmission and distribution project.

When background technology cable elbow-shaped joint is removed, because it is connected firmly, during dismounting, easily from the drawing crack of flex point root, in order to extend its useful life, in the time of need to having a kind of dismounting, can not damage the remover of elbow type joint.

The object that summary of the invention cable elbow-shaped joint four closes hoop remover is: the simple and convenient elbow type joint of removing safely.The technical scheme adopting is: by the principle of very heavy of lifting.What have elbow type joint in arms, four close hoop jack-up and come, pull down elbow type joint.

Cable elbow-shaped joint four closes hoop remover (accompanying drawing) and is one and embraces the elbow type joint equipment section that reclines, and pulls up the utensil of elbow type joint.By one four, closing hoop, a secondary bolt 4 and two nail nippings 5 forms.Four close hoop by upper left hoop section 6, upper right hoop section 3, bottom right hoop section 2, lower-left hoop section 7, through post hinge 1, are hinged and form, and can close and form ring, embrace elbow type joint J; Can divide and chaining, throw off elbow type joint J.On the handle of upper right hoop section 3, inner have a unthreaded hole, and outer have a screw.On the handle of upper left hoop section 6, there is a unthreaded hole.Bolt 4 successively binds round the unthreaded hole of section 3, the unthreaded hole of upper left hoop section 6 through upper right, closes hoop armful be contained on elbow type joint J four.On the handle of lower-left hoop section 7, there is a screw.Article two, nail nipping 5 is screwed in respectively in the screw of upper right hoop section 3 and lower-left hoop section 7.

While removing elbow type head, 1. unclamp bolt 4, make four to close hoop and embrace the elbow type joint equipment section that reclines, leave flange position, termination; And make bolt 4 in upper and lower orientation.2. tight a bolt 4, make four to close banding and hold elbow type joint J.3. tighten 5, two of nail nippings and hocket, first make its tail end withstand the recline installed surface of equipment of elbow type joint J, then what have elbow type joint J in arms, four close hoop jack-up, elbow type joint J is pulled down.

The advantage that cable elbow-shaped joint four closes hoop remover is: 1. simple in structure, easy to use; 2. the masterpiece that pulls up of elbow type joint is used in the axial of the equipment section that reclines, and does not touch its flex point root, therefore can not produce damage at this.

Appended drawings shows that cable elbow-shaped joint four closes hoop remover structural representation.

Embodiment upper left hoop section 6, upper right hoop section 3, bottom right hoop section 2, lower-left hoop section 7 use band steels are manufactured.Interior sticky plastic lining protects 8, has both prevented from damaging colloid elbow type joint, can increase frictional force again.
