Description
Technical field
The utility model relates to a kind of pre-former, refers to especially the special-purpose pre-former of a kind of cable-laid rope.
Background technology
Cable-laid rope claims again " wirerope ", is the steel wire rope that is formed around wirerope core twisting by many steel wire ropes, and in the identical situation of wirerope diameter, the rupture pull force of cable-laid rope is large, and flexibility is good.Usually elevating mechanism, the decoration of exterior wall that the utilization diameter is restricted, intensity of steel wire can't satisfy again the rupture pull force requirement fixed, shipwreck is beaten the specific uses such as waterlogging.But owing to through twisting with the fingers thigh, torsade, three twistings of torsade again, be commonly referred to " cable-laid rope ".
Because the cable-laid rope technological requirement is high, many, the complex procedures of number of share of stock, the twisting difficulty is larger, twisting for the third time particularly, the twist stress of rope strand is difficult to eliminate, and the stress of each rope strand is eliminated inconsistent, stress is difficult to eliminate, and three twistings when twisting with the fingers are not tight so, and reduce fatigue life; And the inconsistent maximum weighted of per share rope strand that causes of the stress of each rope strand elimination is not identical, the stressed meeting of each strand thigh when stressed of wirerope after the twisting moulding is not identical, it is stressed large certain root rope strand or a few rope strands to have occurred, and other stressed little, easy like this cause wirerope wherein one or a few rope strand rupture first, affected service life and the maximum tensile fracture of wirerope.
And obviously, along with the increase of twisting wire rope number of times, the twist stress of rope strand will increase simultaneously, when twisting for the third time, the roller end required distance is required very accurate, and little by little error very likely affects the elimination of rope strand stress and eliminates uneven once in a while.Conventional pre-former generally adopts worm gear structure to regulate, regulate roller end apart from the time accurate not, be difficult to eliminate cable-laid rope for the third time the twist stress that produces of twisting neutron strand steel wire rope or be difficult to make the stress of each rope strand accurate eliminate consistent.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of cable-laid rope special-purpose pre-former, this special use pre-former can be regulated the roller end distance accurately, the twist stress of for the third time twisting neutron strand steel wire rope generation of cable-laid rope is eliminated fully, the stress of guaranteeing each rope strand is eliminated consistent, satisfies that the user is not loose to steel wire rope, the stressed uniform requirement of each rope strand.
For solving the problems of the technologies described above, the technical solution of the utility model is: the special-purpose pre-former of a kind of cable-laid rope, comprise noseplate, shroud, mid-game and hub disk, described hub disk and noseplate are set to integrative-structure, the front end face of hub disk is provided with the center axial region, the center axial region is provided with the centre bore that axially runs through central shaft, hub disk and noseplate, and described mid-game and shroud are sleeved on center axial region periphery successively, between described mid-game and the shroud, be provided with the pad that thickness equates between mid-game and the hub disk; Described shroud, mid-game and hub disk external diameter increase the formation tower structure successively, the some groups of Wire guide rollers corresponding with through wires hole on the noseplate are installed on described shroud, mid-game and the hub disk, axial region upper front in shroud in described center is set with compact heap, be equipped with screw corresponding to position on described compact heap, shroud, the hub disk, the described mid-game position corresponding with this screw is provided with arcuate socket, the center of circle of arcuate socket is positioned on the axis of center axial region, and it is fastening with shroud, mid-game and hub disk that clamping screw passes on compact heap, shroud, the hub disk arcuate socket of screw and mid-game.
As a kind of preferred scheme, described compact heap comprises some cushion blocks identical to thickness.
As a kind of preferred scheme, described hub disk is provided with cable-through hole, and this cable-through hole is corresponding with the Wire guide roller position on the hub disk and be positioned at the rear of this Wire guide roller.
As a kind of preferred scheme, between described Wire guide roller and shroud, mid-game and the hub disk for removably connecting.
After having adopted technique scheme, effect of the present utility model is: because pad is equipped with the pad of consistency of thickness between mid-game and the shroud, between mid-game and the hub disk, thereby can guarantee that the roller end distance between shroud and the hub disk is accurate to technological requirement, the roller end distance is more accurate, and the elimination of each rope strand stress is more abundant, and is also more consistent, wirerope is just not loose during twisting so for the third time, fatigue life is high, and stressed more even between each rope strand, and the maximum tensile fracture that can bear of wirerope is just larger.
Again because described compact heap comprises some cushion blocks identical to thickness, like this, technological requirement more, the cushion block of same thickness in the compact heap is joined between shroud and the mid-game, between mid-game and the hub disk, like this, regulated the roller end distance between shroud and the hub disk, but the cushion block end face is constant to the distance between the hub disk, guarantees to use bolt fixing of same specification.
Again because described hub disk is provided with cable-through hole, this cable-through hole is corresponding with the Wire guide roller position on the hub disk and be positioned at the rear of this Wire guide roller, therefore, each rope strand avoids the rope strand bending excessively to cause rope strand blemish to occur through passing through the Wire guide roller on the hub disk after the break-in of cable-through hole again.
