Description
Technical field
The present invention relates to cable drum traction clamp art more particularly to a kind of tractions of cable drum that reliability is high
Fixture.
Background technology
During the manufacturing of cable, insulation extrudes, stranding, sheath extrude, armouring and oversheath extrude
Each process, being required for doing drawing head makes semi-finished product cable mutually be connected with lower road production process, is finally completed the making of cable.
In cable laying work progress, when greatly enhancing section cable especially with machinery unfolding, cumbersome cable drawing head makes, and needs more
People could be completed with a few hours, not only be easy to injure cable in this way, can also because make cable drawing head when so that cable length is reduced,
And the cable length of engine request is not achieved and scraps.Certain uncertainty is caused to work progress.Cable drum is special at present
With traction clamp structure type mainly based on locking in the form of two kinds of net cover and wedging device.Locking net cover is to use forming wire-rope into interlocking-wire
A kind of round net cover being made into, inserts the cable into trailing cable in net cover, then is tightened net cover on cable with steel wire,
The outer off line set of force effect is shunk and trailing cable moves ahead, although this mode simple structure, the reliability strand of trailing cable is poor,
Cable, which is easy to slip, causes safety accident；Wedging device is that cable is placed in cylindrical type tapered sleeve, in the metallic conductor of cable socket
Interior, one metal chock of indentation makes cable spreading, to realize that cable drum is drawn.Although the loss of this mode cable length
It is small, but poor reliability, cable, which is easy to slip, causes safety accident.Above two fixture is mainly used in cable laying engineering,
And there are no comparatively ideal unfoldings to draw fixture for cable manufacturing process.With regard in current cable laying payingoff construction, being used
Traction clamping fixture reliability it is also not ideal enough.
Through retrieval, Chinese patent grant number is the patent of CN104882830B, discloses a kind of cable drum traction fixture,
Including link, outer sleeve, inner sleeve, clamp system and hold-down mechanism, in above-mentioned patent after the completion of being drawn to cable drum, lead to
It crosses hand hammer and taps outer sleeve or inner sleeve, keep outer sleeve and inner sleeve mutually close, to make cable be detached with fixture, this point
It is easily damaged equipment from mode, and prepressing device compresses by using bolt or loosen cable in above-mentioned patent, thus grasped
It needs to realize bolt presses by other tools or loosens the function of cable during making, it is relatively time-consuming.
Invention content
