Abstract

A strengthened waterproof multi-core cable drawing device belongs to the technical field of mechanical and electrical products and resolves problems that water enters cable conduits from ends of cables when in cable conduit laying. The strengthened waterproof multi-core cable drawing device comprises a conductor pressing sleeve, a sleeve connector, a drawing base, a sealing sleeve, a guide cap, a pull ring, a standard bolt, a nut and a gasket, and is characterized in that the drawing base is provided with three-core 120-degree type or four-core 90-degree type or five-core 72-degree type connecting notches which are used for paying off multi-core cables in environments with water. The strengthened waterproof multi-core cable drawing device has the advantages that the multi-core cables can be drawn by large drawing force to pay off, thereby stopping water entering the cables during a drawing process and avoiding damaging the cables due to twisting.

Description

Strengthen water proof type multicore cable draw-gear

Technical field

The utility model relates to a kind of electronic product technical field, a kind of draw-gear when specifically multicore cable lays unwrapping wire.

Background technology

In the construction of power engineering,, water is often arranged all in the construction pipeline of cable especially in the coastal area and the hypsography low-lying location, after trailing cable passes pipeline, the sealing cap of cable often pulls open, and makes the cable water inlet, brings very big inconvenience and causes the power engineering hidden danger of quality to construction.At present multicore cable lay unwrapping wire, also do not have a kind of reinforcement water proof type multicore cable draw-gear.

Summary of the invention

The purpose of this utility model provides a kind of reinforcement water proof type multicore cable draw-gear.

The purpose of this utility model is achieved in that it comprises conductor compacting sleeve pipe with the cable conductor crimping, the cover pipe connections that is connected with the conductor compacting casing threads, with the cover pipe connections with bolted traction base, the sealing shroud that is connected with the traction whorl of base, what be threaded with sealing shroud draws cap, with draw the draw ring that cap is connected with nuts and washers, can articulate universal external spares such as steel wire rope on the draw ring, thereby realize purpose, it is characterized in that drawing the mouth of connecting trough that has 3 cores, 120 degree types or 4 cores, 90 degree types or 5 cores, 72 degree types on the base by power-equipment haulage cable trailing cable unwrapping wire.

The multicore cable of the utility model indication generally mostly is 3 cores, 4 cores, 5 cores, also can be multicore more.

Advantage of the present utility model and good effect are: tractive effort acts on the conductor of multicore cable, tractive effort is big, draw ring can freely rotate clockwise or counterclockwise during unwrapping wire, do not sprain cable, sealing shroud can be mounted to the cable jacket surface, hold sealing with bands such as PE self-adhesive tapes, can stop cable and in distraction procedure, intake.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 in the accompanying drawing is a structure and connection diagram of the present utility model, and Fig. 2 (a) is the front view of the part drawing of 3 core cable pulling bases, and Fig. 2 (b) is the left view of the part drawing of 3 core cable pulling bases.

Shown in Fig. 1, Fig. 2 (a) and Fig. 2 (b), 1 in the accompanying drawing is the conductor compacting sleeve pipe, and 2 are the cover pipe connections, and 3 are the traction base, and 4 is sealing shroud, and 5 for drawing cap, and 6 is nut, and 7 is draw ring, and 8 is packing ring, and 9 is bolt.

Embodiment

With 3 core cables is example, during concrete operations, at first will draw the sheath of the cable external end head of unwrapping wire, steel band (if having), strippings such as filler are fallen, expose insulated wire cores, stripping is fallen insulating barrier (if interior semi-conductive layer and outer semiconducting layer are arranged, stripping is fallen together), cable conductor is exposed 60 ~ 120mm, with crimping tool (conventional crimp pincers) conductor compacting sleeve pipe 1 is crimped on cable conductor, to overlap pipe connections 2 then is screwed on 1, after three conductors of cable all connect 1 and 2, to draw base 3 with bolt 9 matching standard spare nuts and be connected with three 2, sealing shroud 4 is screwed on 3, until the cable jacket surface, hold with outer round surface to the cable jacket surface of bands such as PE self-adhesive tape from sealing shroud 4, draw cap 5 and be screwed on 4, draw ring 7 is connected by nut 6 and packing ring 8 and draws on the cap 5, and the steel wire rope of external impetus equipment is articulated on the draw ring 7, haulage cable is realized with big tractive effort trailing cable unwrapping wire and the purpose of stopping the cable water inlet.

Claims
