Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a temporary connecting cross arm of a bypass cable for an iron tower as shown in figures 1-4, which comprises a connecting seat 1 and a pressing mechanism 2 arranged on the connecting seat 1, wherein a rod sleeve 3 is welded at one end of the connecting seat 1, a cross bar 4 is clamped at the end part of the connecting seat 1 through the rod sleeve 3, the cross bar 4 is formed by sequentially splicing a plurality of metal branch pipes 41 end to end, a cable mounting seat 5 is fixedly arranged on each metal branch pipe 41, a supporting threaded rod 6 is inserted into the inner side of each metal branch pipe 41, the supporting threaded rod 6 penetrates through the cross bar 4 and is in threaded connection with a threaded hole 7 formed in the side surface of the connecting seat 1, a pressing block 8 is welded at the right end of the supporting threaded rod 6, the pressing block 8 is pressed at the right end of the cross bar 4, when a damaged or deformed metal branch pipe 41 needs to be replaced, the wire rotates to support the supporting threaded rod 6, the end part of the supporting threaded rod 6 is, the supporting threaded rod 6 is pulled out from the inside of the cross bar 4, then each metal branch pipe 41 is pulled apart, a new metal branch pipe 41 is replaced, the supporting threaded rod 6 is inserted and screwed, and the pressing block 8 presses the end part of the cross bar 4 to finish the assembly.
