Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
Also referring to Fig. 1 to Fig. 3, now transmission line of electricity block device provided in an embodiment of the present invention is illustrated.Institute
Transmission line of electricity block device is stated, including building two groups of an iron rake with three to six teeths 1 on the ground, rides upon two be arranged in juxtaposition on two groups of steel towers 1
One end of beam bearing rope 2, the bearing rope 2 is fixed on the ground by earth anchor 3, and the other end is fixed on ground by clump weight 4
On, the transmission line of electricity block device further includes
Mesh sheet 5 rides upon on bearing rope 2 described in two beams, and the mesh sheet 5 is flexible body and can slide along the bearing rope 2；
Mesh sheet 5 can be metal material, or non-metallic material, the present invention in mesh sheet 5 using flexible nylon rope make, tool
It is flexible and can coil.Nylon rope is the rope made of nylon material, and flexible and hardness is relatively high, wear resistant corrosion resistant, will
It is applied on block device, and use is durable.
First block mechanism 6, for the block of long range, including for being unfolded at the top of steel tower 1 described in being located therein one group
The unfolding component 61 of the mesh sheet 5, the fixation kit 62 for being used to fix the mesh sheet 5 at the top of steel tower 1 described in another group；It is right
The first block mechanism 6 is used in the block of long range, fixation kit 62 fixes one end of mesh sheet 5, and the two sides of mesh sheet 5 connect
On bearing rope 2, by unfolding the driving of component 61, mesh sheet 5 can be made to slide on bearing rope 2, so as to neatly adjust
Block length.
Second block mechanism 7 is used for short-range block, including being respectively arranged on the inside of the steel tower 1 and being oppositely arranged
Two groups lift component 71, be wound on two groups described in lift between component 71 and be used for the block component 72 of block；For short distance
Block use the second block mechanism 7, raising can be lifted for block component 72 by lifting component 71, moreover it is possible to make the envelope of block component 72
The length of net changes, to adjust the length for adjusting block.Lift component 71 lift and rotate it is more flexible, can be short
Block operation is carried out in time, does not delay construction speed.
The unfolding component 61 includes the driver 611 for being set to 1 top of steel tower, is fixedly arranged in 1 top of steel tower
Several links 613 and be wound on first reel 612 that first reel 612 of side and the bearing rope 2 are slidably connected
On traction rope 614；The one ends wound of the traction rope 614 is on first reel 612, the other end and close described first
The link 613 of reel 612 connects, and the mesh sheet 5 is connect with the position that the bearing rope 2 connects by the link 613, described
