Problems solved by technology
Once there is internal stress in the new steel wire rope, after a period of use, there will be hazards such as loose strands, core pulling, broken wires, twisting and deformation of the steel wire rope, which will affect the service life of the new steel wire rope and even cause accidents

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...

A method for replacing a wire rope of a crane, comprising the following steps: a) sitting and lying on the hook on the ground, and setting a wire rope drum for a new wire rope on both sides of the hook; b) a hoisting mechanism drives the wire rope drum to rotate and releases the old wire rope; c ) Cut off the two wire ropes between the wire rope balance frame and the hook, and install connecting steel rings on the end faces of the new and old wire ropes; d) Connect the new and old wire ropes with wire rope connection buckles, which include fixed buckles and rotating buckles. Part; the fixed buckle is connected with the new wire rope connecting steel ring, and the rotating buckle is connected with the old steel wire rope connecting steel ring; e) Drive the hoisting mechanism to make the old wire rope pull the new wire rope through the hook pulley-fixed pulley for multiple cycles until the new wire rope is pulled To the position of the wire rope drum; f) Remove the wire rope connection buckle, cut off the rope head at the connection steel ring of the new wire rope, and lower the old wire rope rope head to the ground. At this time, the old wire rope has been completely detached from the hoisting system, and the new wire rope has been introduced Yang 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...
