Abstract
The utility model relates to a wire rope spiral connector used for connecting drawn objects with the wire rope through pulleys in transmission line construction. The wire rope spiral connector is composed of a front shaft nut, bearing balls in the arc-shaped groove of the end surface of the internal sleeve, bearing balls in the arc-shaped groove around the holes on the front end of the rear shaft, an inner sleeve sheathed on the front shaft, the front shaft nut screwed on the end of the front shaft, and the rear shaft screwed outside the inner sleeve. Drills and stop bolts are arranged and fixed between the front shaft and the front shaft nut, and between the inner sleeve and the rear shaft. Because the friction of the bearing balls is very small, when the wire rope is wrung, the front and the rear shafts connecting with the wire rope can rotate freely while drawn objects do not rotate. The utility model has the advantages of big bearing capacity, long service life and safety, and can not be easily damaged.
Description
The utility model relates to a kind of being used in transmission line construction need be by the wire rope and the connector that is led thing, wire rope rotary connector of pulley.
In transmission line construction, often need with some leads of steel cable traction, the general structure that adopts wire rope to be connected with each lead through a towing plate promptly must adopt rotary connector to connect and be integral between wire rope and towing plate, towing plate and lead.Because of rotary connector under the situation of bearing the front and back ends tension force, front and back ends can positive and negative direction rotates freely with the stubborn strength of wire rope itself, so that what make that wire rope under the various situations produces twists moment and can not transmit backward by connector, the moment of twisting that lead produces can not be by connector to front transfer.Thereby do not make and led thing and be subjected to twisting with the fingers the strength effect and overturn, guarantee the construction quality of electric transmission line.
Now the rotary connector of using always in the construction is reasonable inadequately because of structure, and the phenomenon that bearing is cracked, heavy load is not changeed often takes place, and working life is short.
The patent No. 92213725.0 " rotary connector " also provides a kind of and has been used to discharge pulling cable and lead returns the construction equipment of twisting with the fingers moment of torsion, but structure is simple not enough.
The purpose of this utility model be to provide a kind of simple in structure, volume is little and bearing capacity is big, and is not fragile, long service life, safe and reliable wire rope rotary connector.
The utility model is achieved in that the wire rope rotary connector is made up of the forward and backward axle that bolt is installed, and also comprises being installed in the whirligig that is made of preceding spindle nut, interior cover, bearing ball on the forward and backward axle.
Accompanying drawing: structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Front axle (1) is U type opening for front end, and the rear end is the top externally threaded stepped shaft, and rear axle (10) is U type opening for the rear end, and front end is that female blind hole is located in the aperture, and there is a circular groove bottom, hole.Before an end face of spindle nut (8) curve bath is arranged, the curve bath of interior cover (5) for having an outside thread and an end face to have the curve bath with preceding spindle nut (8) end face to be complementary, two curve baths contact with bearing ball (6).
Interior cover (5) is inserted at ladder place, rear portion at front axle (1), and the circle bearing ball (6) of packing in the curve bath of interior cover (5) is screwed into preceding spindle nut (8) again.For making connector when work, can not rotate between front axle (1) and preceding spindle nut (8), join and bore also fixed stop bolt (9) and the aperture is rivetted.Place a loop diameter at bottom annular groove place, rear axle (10) hole and be 1/2～1/4 little bearing ball (7) of bearing ball (6) diameter.
Again rear axle (10) is screwed in outside the interior cover (5), after all assembling, between rear axle (10) and interior cover (5), joins and bore and fixed stop bolt (4), and the aperture is rivetted.Shut auxiliary hole with sealing bolt (3).
When using connector work, steel cord ends and fixed plate (11) front portion inserted the U type opening of forward and backward axle (1), (10) respectively after, be screwed into bolt (2), be fixed in the U type opening.
If will draw two leads with steel cable, the rear through hole place of fixed plate (11) is put into again front axle (1) the U type opening of two other connector, fixing with bolt (2), again connector rear axle (2) U type opening is put in the end of two leads that will draw, fixing with bolt (2), but so just make wire rope be connected just unwrapping wire in aggregates with two leads that led.If will draw four leads just with four connectors, concrete way is as above identical not to be described in detail.
The utility model is compared with prior art: assemble the whirligig that inner sleeve, front spindle nut, bearing ball consist of because adopting between axle, and the frictional force of bearing ball is minimum, in case turning appears in steel wire rope, the front axle that links to each other with steel wire rope or rear axle just can rotate freely by led thing then do not occur the rotation. Because its bearing capacity is big, not fragile, then long service life is again because being fixed with dogbolt after assembling, safe and reliable again.
Claims (4)
1, a kind of wire rope rotary connector, form by forward and backward axle (1), (10) that bolt (2) is installed, it is characterized in that also comprising being installed on forward and backward axle (1), (10), by the whirligig of preceding spindle nut (8), interior cover (5), bearing ball (6), (7) formation.
2, connector according to claim 1, it is characterized in that front axle (1) is U type opening for front end, the rear end is the top externally threaded stepped shaft, rear axle (10) is U type opening for the rear end, front end is that female blind hole is located in the aperture, and the bottom, hole has a circular groove to place a circle bearing ball (7).
3, connector according to claim 1, an end face that it is characterized in that preceding spindle nut (8) has curve bath, in the curve bath of cover (5) for having outside thread and an end face to have the curve bath with preceding spindle nut (8) end face to be complementary, place a circle bearing ball (6) at curve bath, bearing ball (7) diameter is 1/2～1/4 of bearing ball (a 6) diameter.
4, connector according to claim 1 is characterized in that between front axle (1) and preceding spindle nut (8), joins between interior cover (5) and rear axle (10) and bores also fixed stop bolt (9), (4), and the aperture is rivetted.
