Embodiment 1

[0044] A steel strand stay cable threading device, such as Figure 1-1 to Figure 1-3 As shown, the steel strand stay cable threading device includes a winch system 1, a stand system 2, a driver 3 and a transmission chain 5;

[0045] Described winch system 1 comprises line distribution disc 11, cylinder 12, connection disc 13, tripod 14, winch gear disc 15 and rotating shaft 16 (see Figure 2-1 to Figure 2-3 ); the main body of the winch system 1 is a circular drum 12, and the rotating shaft 16 passes through the center of the circular drum to drive the drum to rotate. The tripod frame protruding from the top corner is welded on the connection plate 13 on the rotating shaft; the three top corners of the tripod are respectively equipped with a line distribution plate 11, and the line separation plate 11 is composed of six circular steel plates and a The central shaft is composed of; the winch gear plate 15 is installed outside the tripod 14 on one side of the drum and fixed on ...

Embodiment 2

[0049] A cable-threading method for steel strand stay cables of a cable-stayed bridge, the method is to place the entire steel strand stay cables on the main girder end of the bridge, and pull the anchor end of the steel strand stay cables from the cable tray Draw out, utilize the steel strand stay cable threading device described in embodiment one to pull the steel strand stay cable to the main tower end; One side of the drum is introduced, and the steel strand stay cables are sequentially wound on the drum along the splitting disc, and are exported from the other side of the drum to penetrate into the HDPE round pipe, and the cables are threaded from the tower end to the beam end along the inner wall of the round pipe (see Figure 5 ).

[0050] Its specific steps are:

[0051] A. Installation equipment: Arrange the steel strand stay cable threading device on the cantilevered steel frame at the top of the tower;

[0052] B. Pull the steel strand stay cable to the end of the...

Abstract

A steel strand stay cable penetrating device comprises a winch system, a rack system, an actuator and a transmission chain. The winch system comprises a noseplate, a roller, a connecting plate, a tripod, a winch gear plate and a rotary shaft. The rack system used for supporting the whole winch system is composed of a frame, a supporting frame and a bearing. An actuator assembly is an improved winch, and comprises a motor used as a power source, an actuator gear plate arranged on a winding roll of the winch and a gearbox allowing the gear plate to be mounted. According to the method for adopting the device to achieve penetrating of a cable-stayed bridge steel strand stay cable, a whole roll of the steel strand stay cable is placed at the girder end of a bridge, and the anchoring end of the steel strand stay cable is guided out of the cable roll to a main tower end; the anchoring end of the steel strand stay cable is guided into one side of a roller of the steel strand stay cable penetrating device, the steel strand stay cable is sequentially wound on the roller along the noseplate, the anchoring end of the steel strand stay cable is guided out of the other side of the roller and penetrates into an HDPE round tube, and cable penetrating is carried out from the tower end to the girder end along the inner wall of the round tube.

Description

technical field [0001] The invention relates to a bridge construction device and a construction method, in particular to a cable-threading device and a cable-threading method for steel strand stay cables of a cable-stayed bridge. Background technique [0002] The steel strand cable-stayed bridge adopts parallel steel strand group anchor system as the cable support system. This type of cable is composed of steel strands, outsourced with full-circular HDPE round pipes, and the steel strands need to penetrate into the HDPE round pipes during installation; At present, the construction of steel strand stay cables generally adopts a circular hoisting system, which pulls the steel strand cables from the main beam end to the main tower end through the reciprocating motion of the supporting plate in the HDPE round pipe; the circulating hoisting system is used every When the rope is hung for the second time, it must be re-laid, the workload is large, and the operation is complicated; ...
