Abstract
A kind of multiple steel cable lifting and rope adjustable hanging device that is used for the shaft hoisting system, the assembly pulley of forming by upper and lower pulley and band worm gear.The winch of worm screw, wedge shape wire clips constitute.Top sheave is lifted on and promotes on the steel cable, lower sheave is contained on lifting container (or bob-weight) top, the pulley steel cable passes from upper and lower pulley room, one end is fixed on the lifting container top, the other end is fixed on the winch, be used for automatic compensation promote steel cable when mounted length variation and the running back because of the caused length variation of different permanent elongations, to keep promoting the steel cable stress equalization.
Description
The present invention is a multiple steel cable lifting and rope adjustable hanging device, is applicable to vertical shaft multi rope winding system.
" mine transportation and lifting " book has been introduced a kind of " screw hydraulic rope regulator suspension gear ".This screw hydraulic rope regulator suspension gear is made up of wedge shape wire clips, screw hydraulic rope regulator, adaptor union and four parts of set square, is used for adjusting steel cable length variation when mounted, and the running back is because of the caused length variation of different permanent elongations.When transferring rope, in flexible pipe charged into each hydraulic actuating cylinder simultaneously, oil pressure rose, and promotes piston downwards with pressure oil in elder generation, and the lower end circular nut leaves the chassis.This moment, piston and pressure oil replaced circular nut to bear the load of container.When the circular nut below all hydraulic cylinder bottom dish all left, the tension force that each steel cable bears was equal fully.Stop input pressure oil then, screw the circular nut that is not subjected to load, it is attached to below the chassis.Discharge oil pressure, transfer rope to finish.As the piston in all hydraulic cylinder is pushed up midway location with oil pressure, after oil piping system is full of oil, close the oil circuit gate, circular nut is returned to the screw rod end, just can realize the self-equalizing of each root steel cable tension force in the lifting process.This screw hydraulic rope regulator suspension gear be used to adjust steel cable when mounted length variation or when adjusting the running back because of the caused length variation of different permanent elongations, must stop and adjust.Back for running because of the caused length variation of different permanent elongations, necessary periodic inspection, adjustment.Its accent rope extreme length can not surpass the piston stroke in the hydraulic actuating cylinder.When transferring the rope amount to increase, it is long to adjust rope with the wedge shape wire clips again.Transfer the rope complex process, waste time and energy.When screw hydraulic rope regulator suspension gear is used for automatic compensation steel cable length, piston, piston rod and pressure oil will bear the load of container, add at container and promote or transfer steel cable swing in the process, make between piston rod and cylinder cap and produce lateral stress, quickened the wearing and tearing of piston rod, cylinder cap and oil sealed, caused leakage of oil or scrap.
Task of the present invention is to provide the suspension gear of automatic compensation steel cable length in a kind of work.Its setting range is big, and is simple in structure, long service life.
The present invention adopts by one group of top sheave and one group of assembly pulley that lower sheave is formed.The number of its top sheave equates that with the radical that promotes steel cable the number of lower sheave is that the number of top sheave subtracts one.Each top sheave and lower sheave by bearing with separately the axle be connected.Each top sheave is contained in " Π " shape plate by axle, on the axle pin is arranged, and " Π " shape plate is connected with the wedge shape wire clips with nut by thrust bearing, promotes steel cable and is stuck on the wedge shape wire clips, and top sheave just is lifted on and promotes on the steel cable.Each lower sheave is contained in " Π " shape plate by axle and pin, and " Π " shape plate is contained on lifting container (or bob-weight) top by bolt, nut, or directly " Π " shape plate is welded on lifting container (or bob-weight) top.Upper and lower pulley arrangements in one plane, its horizontal projection is " one " font.The pulley steel cable is pressed top sheave-lower sheave-top sheave-lower sheave ... order pass all upper and lower pulleys, an end is fixed on wire clips on the ring that is welded in lifting container (or bob-weight) top, the other end is fixed on the winch of band worm gear, worm screw.Winch is fixed by bolts on lifting container (or bob-weight) top.If each upper and lower pulley friction force interaxle with it all equals zero, then the suffered vertical direction pulling force of the two steel cable sections on each upper and lower pulley both sides equates.In fact, there are certain friction force in upper and lower pulley and its between centers.When the vertical tension difference of certain root lifting steel cable and adjacent steel cable surpassed the friction force of pulley, pulley rotated, and the length of each steel cable section is changed in the assembly pulley, made the vertical pulling force of each steel cable keep equating (or its vertical pulling force difference is no more than the pulley friction force).As a result, each promotes the power that lifts equal (or its pulling force difference is no more than the pulley friction force) of steel cable.Shake handle or handwheel,, adjust the steel cable amount of twining on the winch, can increase or reduce the total length of steel cable in the assembly pulley, promote length (be equivalent to adjust all and promote steel cable length) thereby adjust by worm gear, worm drive.Multiple steel cable lifting and rope adjustable hanging device provided by the present invention can be used for promoting an end of steel cable, or use simultaneously at two ends.
Design-calculated multiple steel cable lifting and rope adjustable hanging device of the present invention is compared with screw hydraulic rope regulator suspension gear has following advantage: 1. for steel cable length variation when mounted, the present invention one enters mode of operation and can be adjusted, at any time adjusted automatically at work because of the present invention of the caused lifting steel cable of different permanent elongations length variation for the running back, and needn't quantitative check, more need not stop for adjustment; 2. the present invention adopts assembly pulley and winch, and it is simple in structure, makes than being easier to, not requiring and makes such equipment and the engineering factor of oil pressure spare, and its manufacturing cost is much lower; 3. accent rope scope of the present invention is limit by oil cylinder length (increase oil cylinder length, it is created conditions and the hurried increasing of technical risk) unlike prior art.As long as suitably add the length of large pulley steel cable, can guarantee to carry out the actv. adjustment to promoting any length variation that may occur between the steel cable.; 4. also can adjust whole lifting length in the working process by the steel cable amount that twines on the adjustment winch; 5. amount of spin is very little at work for assembly pulley, and its wearing and tearing are also very little, and the maintenance intervals that refuels is long, simple to operate, long service life.
