The specific embodiment
In conjunction with Fig. 1 and Fig. 2; A kind of hoisting crane variable power suspension hook tackle system that hoists; Comprise fixed pulley group 1, lifting hook pulley group 5, suspension hook group 7, steel rope 4 and elevator winch 8; The lifting hook pulley group is connected on the suspension hook group, and above-mentioned steel rope is set out by the elevator winch, pile warp fixed pulley group and lifting hook pulley group.Above-mentioned suspension hook assembly is equipped with can be as the adjustable running block 3 of crane assembly pulley component part; Take the detachable connection structure between adjustable running block and the suspension hook group, be connected on the suspension hook group through modes such as connecting pin 6, shackle, latch or buckles like adjustable running block.The quantity of above-mentioned adjustable running block can be one or more groups, and the quantity of adjustable running block is three groups in this example; Pulley quantity in each adjustable running block can be one or more, and the pulley quantity in this example in each adjustable running block is one.Below the position at fixed pulley group place or fixed pulley group, be provided with running block fixed mount 2; The running block fixed mount is identical with the quantity of adjustable running block; The running block fixed mount is corresponding one by one with the adjustable running block that is positioned at its below; The running block fixed mount is hinged on the wheel shaft of fixed pulley group in this example, can around the wheel shaft of fixed pulley group rotate in case make running block fixed mount base portion towards under; Above-mentioned running block fixed mount can be opening can towards under the slot type structure of bell mouth shape.
In conjunction with Fig. 3 and Fig. 4; On the suspension hook group, disassembled release as adjustable running block; The adjustable running block that obtains discharging is under the action of gravity of suspension hook group; Or under the driving of elevator winch, promote the adjustable running block that obtains discharging until fix (qualification) by its cooresponding assembly pulley fixed mount automatically steel rope, the position maintenance is motionless relatively between the right fixed pulley of adjustable running block that fixed by the running block fixed mount this moment and fixed pulley assembly.The adjustable running block of this moment only plays directional tagging, and lifting hook pulley group and suspension hook group are not had application force, also can not produce relative displacement.This moment, the hoist multiplying power of suspension hook tackle system of this hoisting crane variable power was the pulley quantity of all the residue lifting hook pulley groups shown in Fig. 3 and the pulley quantity decision of the adjustable running block of residue.
Except that aforesaid way, the quantity of the adjustable running block in the utility model can be one group, and the pulley quantity in this adjustable running block can be a plurality of.
When the hoisting crane normal operation; All adjustable running blocks are fixed on the suspension hook group through parts such as connecting pins; Become the part of lifting hook pulley group; Bear the load of suspension hook group jointly, this moment, the multiplying power of lifting hook pulley group was that all lifting hook pulley group pulleys are amount formed, determined according to the steel rope baudrier.If do not consider the efficient of pulley, at this time the load-carrying capacity of suspension hook is maximum, for pull of steel wire multiply by multiplying power; Lifting velocity is the slowest, for rope speed divided by multiplying power.
When hoisting crane need reduce load-carrying ability; When improving lifting velocity, need disassemble release portion or whole adjustable running block, promptly untie the connecting pin of corresponding adjustable running block; Automatically promote the adjustable running block of being disassembled release by steel rope; Until being fixed by its cooresponding running block fixed mount, this moment is motionless relatively with the position maintenance between the right fixed pulley of fixed pulley assembly by the fixing adjustable running block of running block fixed mount, can not produce relative displacement; Be about to this adjustable running block and become leading sheave; Can not apply hoisting force to the lifting hook pulley group, this moment, the multiplying power of lifting hook pulley group was that pulley quantity on the lifting hook pulley group is amount formed with the residue pulley in the adjustable running block of residue, determined according to the steel rope baudrier.If do not consider the efficient of pulley, at this time the load-carrying capacity of suspension hook reduces, for pull of steel wire multiply by multiplying power; Lifting velocity improves, for rope speed divided by multiplying power.
Referring to Fig. 5 and Fig. 6; The utility model also provides a kind of hoisting crane variable power suspension hook coaster integrated system that hoists; Comprise a plurality of suspension hook coaster subsystems with the parallel way assembly, each suspension hook coaster subsystem comprises the above-mentioned hoisting crane variable power suspension hook tackle system that hoists.Reference numeral instruction content identical among the indicated content of each mark among the figure and above-mentioned Fig. 1 to Fig. 4 is identical.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification sheets, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within the protection domain of the utility model.
