Description

Hanging ring fixing device for iron tower angle steel pulley suspension

technical field

The utility model relates to a ring device for hanging a pulley, in particular to a ring fixing device for hanging an iron tower angle steel pulley.

Background technique

At present, there are mainly two working methods for replacing insulators and clamps:

1. Directly hang the transfer rope block and pulley block on the iron tower cross-arm angle steel for construction. This method will make the locking device of the block invalid.

2. Use the rope sleeve method, that is, hang the rope sleeve on the angle steel of the iron tower cross arm. Since the contact surface between the rope sleeve and the angle steel is sheared, it is easy to cause shear wear of the rope sleeve. After the insulation rope sleeve is stressed during live work It is easy to elongate, which directly causes the effective insulation distance to become smaller and reduces the safety of live work.

Especially under some operating conditions, for example, when the vertical span is more than 450 meters on the tower and the erection wire model is 2×LGJ-300, no matter which method is used, there will be a single point concentrated load at the hanging point. Under force, it is easy to cause the deformation of the angle steel at the hanging point and the peeling off of the zinc layer, which will affect the overall force and corrosion resistance of the cross-arm.
