Furthermore, the pulley is made of copper alloy or aluminum alloy material, the limiting anti-drop shaft is made of copper alloy or aluminum alloy material, and the supporting frame is formed by stamping or casting carbon steel or stainless steel.
Further, a through hole is formed in the bottom end of the support frame, a corresponding long through hole is formed in a position, corresponding to the through hole in the bottom end of the support frame, of the upper cover plate of the carrier cable seat body, and a connecting pin penetrates through the support frame through hole and the carrier cable seat body from top to bottom to connect the support frame and the carrier cable seat body; and a copper gasket is arranged between the support frame and the carrier cable seat body.
Furthermore, two sides of the long through hole are provided with transverse through holes, the connecting pin is a movable joint bolt, and a fastening pin is inserted into the transverse through holes and the head pin holes of the movable joint bolt to fix the carrier cable seat body with the connecting pin shaft.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:
1. because the carrier cable and the cantilever are separated through the support frame and the carrier cable seat body, the carrier cable is lapped with the limiting anti-drop shaft through the pulleys in the support frame, the original sliding friction is converted into rolling friction, the abrasion of the carrier cable is greatly reduced, the carrier cable and the cantilever are separated, and the situation that the cantilever is worn and corroded is completely avoided.
2. Compared with the protection strip in the prior art, the protection strip is more convenient to install, shortens the construction period, and reduces the construction difficulty and strength.
