Embodiment Construction
[0022] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0023] The hanging cable circulation device includes a pay-off reel, a winch, a traction device, and a cable puller, wherein the pulley is arranged on the beam, and the cable puller is arranged at the tower end, and the cable puller and the pulley are connected by a wire rope, and the wire rope passes through two A set of guide wheels is used for steering. When in use, one end of the steel strand on the pay-off reel is connected to one end of the traction groove of the traction device, and the other end of the traction device is connected to the hoist through a wire rope to form a closed rope system. The cable puller is used for tensioning the pre-tensioned steel strand.
[0024] The anchoring system of the cable-stayed cables of the parallel steel strands adopts a sealing cylinder to replace the combination of the support cylinder and the ext...
