Usually, wind cables are arranged on two sides of a cable tower, one end of each wind cable is anchored on the cable tower, and the other end of each wind cable is anchored on a ground anchor. The ground anchor generally adopts gravity type anchorage, because bulky, area is big, and cable tower both sides all set up the anchorage and not only can receive the construction site limitation sometimes, and construction cost is high moreover, and the accent cable is long for a time, influences the construction progress.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem, a system and construction method that cable crane cable tower wind cable carries out the anchor is provided, can anchor the wind cable fast, adjust the cable tower straightness that hangs down to reduce construction cost as far as possible.
The utility model discloses a cable hanger cable tower wind cable anchoring system, the sidespan side of both sides cable tower sets up an anchorage respectively, and every cable tower top is provided with the anchor roof beam, is connected with back wind cable, its characterized in that between anchorage and anchor roof beam: and one end of the ventilation cable is directly fixed on the anchoring beam at the top of one cable tower, and the other end of the ventilation cable is fixed with the tower top anchoring beam of the other cable tower through a cable pulley.
The utility model discloses set up the anchorage in the side of striding of every cable tower, the side of striding of two cable towers adopts the ventilation cable taut, saves two anchorages than current anchor system, and the advantage is unilateral anchor, single-ended accent cable, and construction speed is fast, has shortened and has transferred the cable time, has practiced thrift construction cost by a wide margin, receives construction site environmental constraint little, and the anchor dependable performance, and the security is high, can satisfy the site operation requirement.

Detailed Description
As shown in fig. 1 and 2, the utility model discloses a cable tower wind cable anchor system sets up an anchorage 2 respectively in the sidespan side of both sides cable tower 1, and every cable tower top is provided with anchor beam 3, and anchorage 2 is connected with back wind cable 4 with anchor beam 3 within a definite time, is connected with between the midspan side of two cable towers and leads to wind cable 5, lead to wind cable 5 one end snap-on the anchor beam at a cable tower top, the other end is fixed through the top of the tower anchor beam of cable coaster 6 with another cable tower.
The rear wind cable is made of steel stranded wires, and the ventilation cable is made of steel wire ropes.
As shown in fig. 3 and 4, the cable adjusting pulley 6 comprises a first fixed pulley 61 and a second fixed pulley 62 connected through a connecting plate, and a first movable pulley 63 and a second movable pulley 64 connected through a connecting plate, wherein the first fixed pulley 61 is connected with the anchoring beam 3 at the top of the cable tower through a fixed steel cable 65, and the second fixed pulley 62 is connected with the second movable pulley 64 through a cable adjusting steel cable 66; one end of the ventilation cable 5 directly fixed with the anchoring beam is fixed by a rope clamp 7 after passing around the tower top anchoring beam, and the other end of the ventilation cable 5 is fixed by the rope clamp 7 after passing around a first movable pulley 63 of the cable adjusting pulley.
The concrete construction method of the wind cable anchoring system of the cable crane tower comprises the following steps:
(1) anchors 2 are respectively arranged on the side span sides of cable towers 1 at two sides, an anchoring beam 3 is arranged at the top of each cable tower, a rear wind cable 4 is connected between the anchor 2 and the anchoring beam 3 at the top of the tower, one end of the rear wind cable 4 is permanently anchored with the anchor, and the other end of the rear wind cable is temporarily anchored with the anchoring beam at the top of the tower;
(2) connecting a cable adjusting pulley 6 on an anchoring beam at the top of a cable tower, wherein the cable adjusting pulley 6 comprises a first fixed pulley 61 and a second fixed pulley 62 which are connected through a connecting plate, and a first movable pulley 62 and a second movable pulley 64 which are connected through the connecting plate, the first fixed pulley is connected with the anchoring beam at the top of the cable tower through a fixed steel wire rope 65, and the second fixed pulley is connected with the second movable pulley through a cable adjusting steel wire rope 66;
(3) one end of the ventilation cable 5 is wound around the anchoring beam at the top of the other cable tower and is fixed by a rope clamp 7; the other end of the ventilation cable is pulled to the top of a cable tower provided with a cable adjusting pulley 6 by a traction cable, and the ventilation cable is fixed by a rope clamp 7 after passing through a first movable pulley 63 of the cable adjusting pulley;
(4) synchronously tensioning the rear wind cables 3 of the two cable towers by adopting a hydraulic jack at the tops of the two cable towers 1, and adjusting the distance between the second fixed pulley 62 and the second movable pulley 64 by tightening a cable adjusting steel wire rope 66 on the cable adjusting pulley 6 while tensioning the rear wind cables, thereby tensioning the ventilation cable 5; and adjusting the verticality of the wind cable and the ventilation cable to meet the design requirement, enabling the two sides of the cable tower to be stressed consistently, and keeping balance and verticality.
