Portable detachable high tower examines and repair instrument relates to a maintenance instrument. The operation and the maintenance of high tower, difficulty, chronic is overhauld to efficiency low, can't ensure the operation of this circuit safe and reliable, can not compromise the cost of maintenance and the security of maintenance. The utility model discloses a rotating between the seat frame and the pedal frame that are used for connecting the mounted frame of safety rope, the link that links to each other with the mounted frame lower extreme, are connected with the link, link and pedal frame and being connected, the lower extreme of link is continuous with the seat frame lower extreme, and it is continuous with the lower extreme of link to ride the upper end of putting up, both sides are equipped with first pulley, second pulley respectively about the mounted frame, and first pulley department is equipped with and is used for restricting the gliding brake equipment of safety rope. This technical scheme dismantles, assembly process all can accomplish reliable and simple rapidly. This technical scheme examines and repair instrument simple structure, the reliable operation, and the operating cost is low, maintenance efficiency is high.
