The invention relates to the field of hoisting machinery, and discloses a standard knot introduction roller, a climbing device and an introduction method. The leading-in roller comprises a roller frame, an upper clamping plate and a lower clamping plate which are arranged in the vertical direction are arranged on the roller frame, the lower clamping plate can support a web member of a standard knot, the upper clamping plate and the lower clamping plate form a first clamping opening, and the first clamping opening can be connected with a main chord member of the standard knot in a clamping mode; the rotating shaft is fixed on the roller carrier and extends towards the outer side of the roller carrier; and the roller sleeves the rotating shaft and is positioned on the outer side of the roller frame. The web member of the standard knot is supported by the lower clamping plate, and the main chord member of the standard knot is clamped by the first bayonet, so that the introduction roller is mounted at the bottom of the standard knot, no special requirement on the specific structure of the standard knot exists, the requirement on the operation space is low, the introduction problem of the tenon standard knot is solved, and the effects of wide application range and convenience in disassembly and assembly are achieved.
