Abstract
The utility model discloses a convenient waterproof cable traction head. The cable traction head consists of a traction main body (1), a traction body (2), a locking nut (3), a sealing ring (4) and a waterproof gland (5). According to the cable traction head, a locking opening (6) is formed at the end of the traction main body (1), and the traction main body (1) is tightly locked and pressed on a cable outer sheath through the locking nut (3) to ensure that the traction main body (1) is in tight compression joint with a cable, so that the cable traction head has high enough tensile strength and cannot drop in the traction process; under the action of the waterproof gland (5), the sealing ring (4) and a sealant, external water cannot enter the traction head; and the whole mounting process of the traction head is simple and fast, and the working efficiency can be doubled. The convenient waterproof cable traction head is reasonable in structure, high in tensile strength, convenient to mount, reliable and good in sealing effect and can effectively fulfill the aim of water proofing, and a novel practical product is provided for the traction head for unwinding medium and high voltage cables.
Description
Technical field
The utility model relates to the accessory that a kind of cable laying is installed, and exactly belongs to a kind of cable unwrapping wire drawing head.
Background technology
Development along with electric utility, domestic power transmission and transformation field, it is very universal that large industrial enterprise use medium and high voltage cable is carried out power delivery, but medium and high voltage cable is in laid processes, because traditional drawing head exists structural unreasonable, cause lay the time easily the coming off or the easy phenomenon such as water inlet of drawing head, mainly be since cable in when traction, the pulling force that drawing head is subject to, do not reach due tensile strength, sealing effectiveness is bad simultaneously, when transporting and laying, intake easily, installation process need be welded, the techniques such as filling is plumbous waste time and energy, bring many inconvenience to construction, simultaneously since water inlet or drawing head come off to construction, cable uses department, cable manufacturer causes very large loss.
The utility model content
The purpose of this utility model is a kind of safe, practical drawing head convenient and that water resistance is strong to be installed for what provide that a kind of middle high cable uses when laying unwrapping wire.
The utility model is comprised of traction main body, traction body, locking nut, sealing ring, waterproof gland, end and the middle part overcoat of traction main body one end have screw, muzzle has screw in traction body one end, and traction main body cover has the end of screw and locking nut to link together by thread; Traction body one end links together by screw and traction main body middle part, and the traction body other end has towing pad; Waterproof gland and locking nut link together by thread, and sealing ring is placed in the locking nut inboard between traction main body and waterproof gland, and traction main body 1 and waterproof gland are fixed sealing ring.Wherein, traction main body one end has lock opening, lock opening is little horn mouth, to draw main body by locking nut is locked on the cable, by the fluid sealant inlet injection fluid sealant on the section in the middle part of the traction main body and on the locking nut side, whole drawing head is securely fixed on the cable body again.Have the spanner groove on locking nut outer surface and the waterproof gland outer surface, be mainly used in tightening the outer and waterproof gland of locking nut, have towing pad on the traction body and be mainly used in trailing cable.
Drawing head installation process: first waterproof gland, sealing ring are enclosed within on the cable socket, the conductor of the cable external end head that will draw again inserts in the traction main body, by hydraulic press cable conductor and traction main body firmly are crimped on together, then locking nut is enclosed within on the traction main body, utilize the open slot on the locking nut that locking nut is pushed ahead by screw, locking nut progressively compresses the lock opening on the traction main body, the traction main body is locked tightly be pressed on the cable jacket; Utilize the open slot on the waterproof gland to be pressed on waterproof gland, sealing ring on the port of traction main body by screw; Simultaneously, traction body is connected on the traction main body by screw, last, be injected into locking nut in by fluid sealant fluid sealant and the traction main body in, finish whole installation process.
The utility model has the advantages that: because the traction body end has lock opening, cable conductor is pressed in the traction main body, to draw main body by locking nut locks tightly and is pressed on the cable jacket, guaranteeing to draw main body closely is crimped on cable, has enough large tensile strength, in distraction procedure, can not come off, by the effect of waterproof gland, sealing ring, fluid sealant, guarantee that outside moisture can't enter drawing head inside simultaneously; Whole installation process simple and fast of while, operating efficiency promotes more than one times.
Utility model tensile strength rational in infrastructure is large, and is easy for installation, reliability and durability, can improve cable drawing head installation quality, simultaneously, good sealing effect between each installed part of cable drawing head can arrive the purpose of waterproof between drawing head and the cable jacket effectively.
