Abstract
The invention relates to a penetrating and winding method of a large-diameter variable-amplitude steel wire rope of a large moving-arm type tower crane. The penetrating and winding method comprises the following steps: with a small-diameter steel wire rope as a traction rope, bundling the head end of the traction rope on a winding drum of a lifting winch, completely winding the traction rope on the winding drum, then enabling the tail end of the traction rope to pass by variable-direction pulleys, after completing the whole penetration and winding in the two pulley groups, connecting the tail end of the traction rope with a chicken-heart-shaped ring of a variable-amplitude steel wire rope, then operating the lifting winch and a variable-amplitude winch to wind the traction rope into the lifting winding drum again, and guiding the variable-amplitude steel wire rope out of a variable-amplitude winding drum so as to utilize the lifting winch to wind the large-diameter variable-amplitude steel wire rope into the two pulley groups by the traction rope. The penetrating and winding method has the advantages that the steel wire rope with the diameter being smaller than the diameter of the variable-amplitude steel wire rope is taken as the traction rope, one end of the steel wire rope is fixed on the lifting winding drum, the whole penetration and winding are finished in the two pulley groups, and the lifting winch is utilized as the traction power for penetrating and winding the variable-amplitude rope.
Description
Technical field
The invention belongs to large-scale movable arm type tower machine installing/dismounting field, relate to the winding method of a kind of major diameter (>=30mm) variable-amplitude steel wire rope in two luffing assembly pulleys.
Background technology
Major diameter variable-amplitude steel wire rope wear around, it is the requisite important step of movable arm type tower machine installing/dismounting, when actual installation is dismantled, a rope made of hemp is normally adopted to couple together as the capel of messenger and variable-amplitude steel wire rope, use the method for manpower wear with carrying out a pulley pulley around, finally complete the whole of two assembly pulleys and wear around work.Obviously, not only efficiency is low for this method, labour intensity and difficulty are all large, and wear that to walk around journey be carry out at height in the air due to whole, the safety of operating personal is difficult to be guaranteed.
Summary of the invention
Object of the present invention walks around the operator safety existed in journey is difficult to be guaranteed, inefficiency, labour intensity and difficulty are large problem and the winding method that provides a kind of large-scale movable arm type tower machine major diameter variable-amplitude steel wire rope wearing in order to the movable arm type tower machine major diameter variable-amplitude steel wire rope that overcomes above-mentioned prior art and exist
Technical scheme of the present invention is:
A kind of winding method of large-scale movable arm type tower machine major diameter variable-amplitude steel wire rope, it is characterized in that carrying out according to the following steps: use the steel rope of minor diameter as hauling rope, first the head end bundled device of hauling rope is bundled in and hoists on the reel of winch, and hauling rope is all rolled onto on reel, again by hauling rope end through angle pulley, according to variable-amplitude steel wire rope wear around reverse direction, complete in two assembly pulleys and all reversely wear around rear, end is connected with the capel of variable-amplitude steel wire rope, then hoist winch and luffing winch is handled, hauling rope is involved in hoisting drum again, variable-amplitude steel wire rope is drawn from amplitude-changing drum, thus utilize the winch that hoists to be worn major diameter variable-amplitude steel wire rope around in two assembly pulleys by hauling rope.Diameter >=the 30mm of variable-amplitude steel wire rope.
Described traction power is provided by the tower machine winch that hoists itself.
The diameter of described hauling rope is 8-15mm.
The steel rope that the present invention uses diameter less than variable-amplitude steel wire rope is as hauling rope, variable-amplitude steel wire rope wear around front first hauling rope is completed in two assembly pulleys all wear around, one end bundled device of hauling rope is fixed on hoisting drum, utilize tower machine hoist winch as variable amplitude rope wear around traction power, adopt pulley to change the direction of hauling rope when using hauling rope.
Accompanying drawing explanation
Fig. 1 is variable-amplitude steel wire rope of the present invention wearing around schematic diagram in two assembly pulleys.
Detailed description of the invention
The invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, the present invention specifically wears and around step is:
A, preparation length are that the steel rope of about 12mm is as hauling rope 6 than variable-amplitude steel wire rope 3 length more than the 20 meters diameters of tower machine, two pulleys (2 tons) are as angle pulley (4,8), six wire clips, the bundled device of 6 meters long, chain and tackle blocks of 1 ton supporting with hauling rope, the diameter of variable-amplitude steel wire rope is 40mm.
B, with bundled device, the head end of hauling rope 6 to be fixed on the hoisting drum 1 of the winch that hoists, and hauling rope 6 is all rolled onto on hoisting drum 1.
C, the anti-hopping safety pole removed on two groups of luffing pulleys (5,7), tower top and rising arm root joint install an angle pulley (4,8) respectively, and are hung over by chain and tackle block on the hanger hole of tower top.
D, operation hoist winch, make its descending at slow speed, hauling rope 6 is slowly drawn from hoisting drum 1, by hauling rope 6 end through two angle pulleies (4,8) after, again by hauling rope 6 according to variable-amplitude steel wire rope wear around reverse direction, complete between two assembly pulleys (5,7) all wear around.
E, the end of hauling rope 6 to be guided on amplitude-changing drum 2, and be connected with wire clips with the capel of variable-amplitude steel wire rope head end.
F, operation hoist winch, make it hoist at a slow speed, hauling rope 6 is slowly involved in hoisting drum 1 again, operate luffing winch simultaneously, make its arm that falls at a slow speed, variable-amplitude steel wire rope 3 slowly drawn, variable-amplitude steel wire rope 3 along with hauling rope 6 slowly two groups of pulley rooms complete wear around.The speed of two winchs should be kept in whole process basically identical;
G, all wear after complete when variable-amplitude steel wire rope 3, with the capel pull-up of chain and tackle block by variable-amplitude steel wire rope, insert tower top and connect otic placode, and use special pinned connection;
H, the anti-hopping safety pole installed on luffing assembly pulley (5,7), take off hauling rope from hoisting drum 1, dismounting chain and tackle block and angle pulley (4,8).
Claims (3)
1. the winding method of one kind large-scale movable arm type tower machine major diameter variable-amplitude steel wire rope, it is characterized in that carrying out according to the following steps: use the steel rope of minor diameter as hauling rope, first the head end bundled device of hauling rope is bundled in and hoists on the reel of winch, and hauling rope is all rolled onto on reel, again by hauling rope end through angle pulley, according to variable-amplitude steel wire rope wear around reverse direction, complete in two assembly pulleys and all wear around rear, end is connected with the capel of variable-amplitude steel wire rope, then this tower crane lifting winch and luffing winch is handled, hauling rope is involved in hoisting drum again, variable-amplitude steel wire rope is drawn from amplitude-changing drum, thus utilize the winch that hoists to be worn major diameter variable-amplitude steel wire rope around in two assembly pulleys by hauling rope.
