The bolt is band handle bolt.
The bearing rope is Di Nima bearing rope.
The protective net includes glass reinforced plastic fender rod.
Compared with prior art, the invention has the following advantages that
(1) the block construction working worked continuously will be needed to split into two processes originally, by the used time it is longer and exist not It determines and is completed during the linked network work of factor advances to preparation of construction, not by time restriction.
(2) after closing a road to traffic or have a power failure, bearing rope and operating rope is conventionally carried out across object is spanned, is adjusted after fixing As long as after loosening the rope gripper on the fixture of front end, protective net can be pulled to designated position, complete block operation, reduced big Amount needs the times such as linked network adjustment originally, reduces the time of road closure or power failure.
(3) it is completed during advanceing to preparation of construction because of part work, when reducing usual manner block while what is needed applies Work personnel amount.
(4) first fixed pulley groups, the second fixed pulley group and third fixed pulley group respectively include the fixed pulley of two linkages, mention Strong mechanical performance extends the fixed pulley group service life.
(5) three fixed pulley groups have pulley locking mechanism, facilitate operation.
(6) presser type fixture uses spring pressing plate, and using bolt fastening, no loose mail is fallen, easy to operate.
