Embodiment Construction

[0026] see Figure 1 to Figure 5 , the replacement method of crane wire rope of the present invention, it comprises the steps:

[0027] a) Put the crane hook 1 on the ground, place a wire rope drum 3, 3' and the corresponding support on both sides of the hook 1, and place a new wire rope 2, 2' and the corresponding support. The hook 1 and the wire rope drum 3, The distance between 3' is controlled at 3-4 meters, and the rotation of the wire rope drum and the release of the new wire rope are ensured;

[0028] b) The hoisting mechanism 4 of the crane drives the wire rope reel 5 to rotate, and releases the old wire ropes 6, 6' of the wire rope reel 5, so that the old wire ropes 6, 6' are completely relaxed, and the old wire ropes 6, 6' remain on the wire rope reel 5 The number of rope loops is 2 to 3 (excluding the fixed loop of the reel wire rope);

[0029] c) Cut off the two steel wire ropes 6, 6' between the steel wire rope balance frame 7, 7' on both sides of the fixed pull...

Abstract

The invention provides a method for replacing crane steel wire ropes. The method comprises the following steps that (a), a lifting hook is seated on the ground, and each of the two sides of the lifting hook is provided with a steel wire rope cylinder of a new steel wire rope; (b), a winch mechanism drives a steel wire rope winding drum to rotate to release old steel wire ropes; (c), two steel wireropes between a steel wire rope balance frame and the lifting hook are cut off, and connecting steel rings are installed on the end surfaces of the old steel wire ropes and the new steel wire ropes;(d), a steel wire rope connecting buckle is used for connecting the new steel wire ropes and the old steel wire ropes, the steel wire rope connecting buckle comprises a fixing buckle and a rotating buckle, the fixing buckle is connected with the new steel wire rope connecting steel ring, and the rotating buckle is connected with the old steel wire rope connecting steel ring; (e), the winch mechanism is driven to enable the old steel wire ropes to pull the new steel wire ropes to pass through a lifting hook pulley, namely a fixed pulley, for a plurality of circulations until the new steel wireropes are pulled to the position of the steel wire rope winding drum; and (f), the steel wire rope connecting buckle is disassembled, the rope head of the new steel wire rope steel ring is cut off, the rope heads of the old steel wires are put down to the ground, at the moment, the old steel wire ropes are completely detached from the winch system, and the new steel wire ropes are guided into thewinch system.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a method for replacing steel wire ropes of a crane. Background technique [0002] When the steel wire rope of the lifting equipment is used for a certain period of time, the steel wire rope will deteriorate due to factors such as wear, corrosion, deformation, etc., and the steel wire rope that has reached the scrapping requirement must be replaced online. The existing technology is to remove one end of the old steel wire rope installed on the balance frame, use hemp rope to lower the head of the old steel wire rope to the ground, and perform brazing connection of the new and old steel wire ropes on the ground by gas welding, and then use the hoisting device hoisting mechanism Powered by itself, the old steel wire rope pulls the new steel wire rope, pulls the head of the new steel wire rope to the hoisting equipment drum, fixes the new wire rope head that has been drawn in place on the drum, c...
