2, the reel manufacturing of car spiral drum slot is easy to control, and the cycle is short, and cost is low.Both improve the work efficiency of crane, also saved cost to a great extent.
3, storage grooving, conductor rope groove and conductor rope platform are rational in infrastructure, and manufacture craft is simple, and cost is low, is convenient to promote the use of.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, terminal retaining rope wall, 1-1, conductor rope groove I, 2, the storage grooving, 3, the ground floor rope, 4, second layer rope, 5, the 3rd layers of rope, 6, the conductor rope platform, 7, grooving, 8, first end retaining rope wall, 8-1, conductor rope groove II, 9, rope wedge hole, 10, reel.
The specific embodiment
As shown in drawings: a kind of hoister in large tonnage is with the reel with automatic adjusting flake down function, and it is by reel 10, just end retaining rope wall 8, terminal retaining rope wall 1 and rope wedge hole 9 are formed.Described reel 10 is round tube, makes grooving 7 on the periphery of round tube, and described grooving 7 is the car spiral drum slot.The described retaining of end just rope wall 8 is fixed at the two ends of reel 10 with terminal retaining rope wall 1, near first end retaining rope wall 8 places rope wedge hole 9 is arranged on the reel 10.It is characterized in that: make storage grooving 2 in reel 10 and terminal retaining rope wall 1 junction, make conductor rope groove I 1-1, the joint portion arc transition of storage grooving 2 and conductor rope groove I 1-1 on retaining rope wall 1 inwall endways.Make conductor rope platform 6 at reel 10 with just holding retaining rope wall 8 junctions, just holding retaining rope wall 8 inwalls to make conductor rope groove II 8-1, the joint portion arc transition of conductor rope platform 6 and conductor rope groove II 8-1.
The degree of depth of described storage grooving 2 is identical with grooving 7 degree of depth; The length of storage grooving 2 is the diameter of 2 to 2.5 times of steel ropes.
The degree of depth of described conductor rope groove I 1-1 is 1/10th of wirerope diameter; The height of conductor rope groove I 1-1 is a little more than the line of centers of second layer rope 4.
The width of described conductor rope platform 6 is slightly less than the diameter of twice steel rope; The height of conductor rope platform 6 equals the Up Highway UHW of ground floor rope 3.
The degree of depth of described conductor rope groove II 8-1 is 1/20th of wirerope diameter; The height of conductor rope groove II 8-1 is a little more than the line of centers of the 3rd layer of rope 4
As shown in drawings: described grooving 7 is the car spiral drum slot, and the reel manufacturing process is to cast out the reel blank earlier, and then realize by machinework.The manufacturing of Casting Parts blank is simple, is easy to control, and the finished product accuracy of realizing by machinework is good, the efficient height, and integrated cost is low.
As shown in drawings: during use, steel wire rope head is fixed on the rope wedge hole 9, steel rope enters first grooving 7 of end retaining rope wall 8 one ends just by rope outlet, along with the rotation of reel 10, steel wire disk is in all groovings 7, after steel wire disk arrives last grooving 7, enter storage grooving 2, because the length of storage grooving 2 is the diameter of 2 to 2.5 times of steel ropes, two steel ropes in the storage grooving 2 are no longer fettered, can be according to stressing conditions free adjustment position.
Steel rope by ground floor in the change rope process of the second layer, the ground floor steel rope is subjected to the pressure of second layer steel rope, in storage grooving 2 and conductor rope groove I 1-1, freely adjust the position, give antagonistic force of second layer steel rope simultaneously, allow steel rope become rope smoothly to the second layer.
After second layer steel wire disk arrives last grooving 7, enter conductor rope platform 6, because the height of conductor rope platform 6 equals the Up Highway UHW of ground floor rope 3.Steel rope can be according to stressing conditions free adjustment position at conductor rope platform 6 places.
In the change rope process of steel rope by three layers of the second layers to the, second layer steel rope is subjected to the pressure of compound steel silk rope and freely adjusts the position in conductor rope platform 6 and conductor rope groove II 8-1, give antagonistic force of compound steel silk rope simultaneously, allow steel rope become three layers in rope to the smoothly.So can realize the smooth flake down of steel rope, avoid the disorder cable phenomenon, reduce steel rope abrasion, prolong the steel rope purpose in service life thereby reach.
