Height h2 is 40cm, and the bottom surface surrounding of lead screw bracket 1 is provided with 4 through-holes, is fixedly connected, is avoided with cross-arm by fixing bolt 10
Lead screw 4 occurs left and right, tilts forward and back after stress, supports entire mechanism, 1 bottom of lead screw bracket also has and cross-arm length side
To the U-lag matched, so that lead screw bracket 1 and cross-arm is reached height and cooperate；
The lead screw 4 is mounted on lead screw bracket 1, and one end is fixedly connected with steel wire 5 is drawn high, and the other end passes through lead screw bracket
1 top and screw drive mechanism, are placed in lead screw bracket 1, are to promote the main component for drawing high steel wire 5；
It includes: lead screw handle 3-1, worm screw 3-2, worm gear and nut that the screw drive mechanism, which is mounted in lead screw bracket 1,
3-3；The nut 3-3 is mounted on lead screw bracket 1, and worm gear is placed in inside nut 3-3, the one end the worm screw 3-2 and nut 3-3
Internal worm gear engagement, the other end are connect with lead screw handle 3-1；It there also is provided guide bearing 3-4 at the top of the lead screw bracket 1,
Lead screw 4 is oriented to screw drive mechanism cooperation；
It is specific: the free end of lead screw handle 3 being rotated clockwise, worm screw 3-2 rotation, the snail inside nut 3-3 are driven
Wheel is engaged with worm screw 3-2, is radially risen by worm-gear driven lead screw 4, and the longest extension elongation h1 of lead screw is 20cm；By lead screw
The free end of handle 3 rotates counterclockwise, drives worm screw 3-2 rotation, and the worm gear inside nut 3-3 is engaged with worm screw 3-2, passes through snail
Wheel drive lead screw 4 radially declines.
The steel wire 5 that draws high is two, and one end is connect with lead screw 4, and the other end is distributed in 6 two sides of preformed armor rods of optical cable 9, this
In example when 4 extension elongation longest of lead screw, the angle for drawing high steel wire 5 and lead screw 4 is 45 °, draws high steel wire 5 and passes through triangle cord holder 8
It is connect with optical cable 9, intermediate cam cord holder 8 is two, and spacing L is 1.3m, and two triangle cord holders are drawn high steel wire 5 and mentioned jointly
It rises, achievees the purpose that Synchronous lifting optical cable 9.
Embodiment 2, this example and embodiment the difference is that: the height h1 of lead screw bracket described in this example 1 be 35cm,
