The column of fixed ladder is stuck in centre.
It is to the further improvement of the invention done：The landing ladder is terraced for framework of the both sides with standpipe；It is described board-like
Link up with and be provided with hook hole and hook passage for flat board, the flat board, the diameter of the hook hole is more than the straight of the cross bar of fixed ladder
Footpath, hook hole are connected above hook passage and with hook passage.
Also include transverse tube, hanging pulley, assembly pulley, drawstring and hanging basket；The transverse tube is transverse in pipe, the assembly pulley
Installed in one end of transverse tube, the hanging pulley is arranged on the top of transmission of electricity tower bar, one end connection hanging basket of the drawstring, drawstring
The other end through hanging pulley and assembly pulley and extend to ground.
Also include anchor ear and fixed seat, the anchor ear is fastened on transmission of electricity tower bar bottom periphery, and the fixed seat is provided with
Suit lands the sleeve of terraced standpipe, and fixed seat is connected by bolt with anchor ear.
It is using beneficial effect caused by above-mentioned technical proposal：Two board-like hooks of the present invention consolidate transmission of electricity tower bar
The cross bar column of fixed ladder is stuck in centre, and the sleeve on anchor ear will land terraced standpipe and entangle, it is ensured that maintenance ladder and transmission of electricity tower bar
Fixed ladder is reliably connected, and also effectively can prevent maintenance ladder from rocking even if blowing hard, and can also utilize hanging pulley and assembly pulley court
Tower bar of transmitting electricity top conveying maintenance equipment, the convenient maintenance construction of the present invention, saving of work and time are laborsaving, it is ensured that maintenance safety, improve labor
Efficiency of movement.
