Technical field
The present invention relates to a kind of construction machinery and equipment, being specifically related to hoister in large tonnage with having the reel automatically regulating flake down function.
Background technology
The hoisting speed reducer reel of engineering hoisting crane, is mainly divided into two kinds: a kind of is traditional car spiral drum slot reel, and another kind of is casting dual slope rope groove drum.The former advantage is that production is easy to realization, cost of product is low, and shortcoming is that disorder cable phenomenon is many.The advantage of the latter is reduction of the disorder cable probability of steel rope, and shortcoming is that product manufacturing is complicated, and the cycle is long, cost is high.In construction machinery industry, reel disorder cable is long-standing technical barrier, and the direct impact of disorder cable is exactly the wearing and tearing causing steel rope, steel rope long term wear, and necessary timely more change steel rope, not only can cause cost to increase, also can affect work efficiency.As changed not in time, great potential safety hazard can be caused.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of hoister in large tonnage with having the reel automatically regulating flake down function, keep off at reel and end wall junction of restricting to make and store up grooving, end gear rope wall inwall makes conductor rope groove I, the joint portion arc transition of storage grooving and conductor rope groove I, regulates steel rope to coil the second layer smoothly by ground floor.
Make conductor rope platform at reel and first terminal block rope wall junction, first terminal block rope wall inwall makes conductor rope groove II, the joint portion arc transition of conductor rope platform and conductor rope groove II, regulate steel rope to coil third layer smoothly by the second layer.
The present invention is achieved through the following technical solutions: a kind of hoister in large tonnage regulates the reel of flake down function automatically with having, and it is made up of reel, first terminal block rope wall, end gear rope wall and rope wedge hole.Described reel is round tube, and the periphery of round tube makes grooving, and described grooving is car spiral drum slot.Described first terminal block rope wall and end gear rope wall are fixed on the two ends at reel, and reel has rope wedge hole near first terminal block rope wall place.It is characterized in that: keep off at reel and end wall junction of restricting and make and store up grooving, end gear rope wall inwall making conductor rope groove I, the joint portion arc transition of storage grooving and conductor rope groove I.Make conductor rope platform at reel and first terminal block rope wall junction, first terminal block rope wall inwall makes conductor rope groove II, the joint portion arc transition of conductor rope platform and conductor rope groove II.
The degree of depth of described storage grooving is identical with the grooving degree of depth; The length of storage grooving is the diameter of 2 to 2.5 times of steel ropes.
The degree of depth of described conductor rope groove I is 1/10th of wirerope diameter; The height of conductor rope groove I is a little more than the line of centers of second layer rope.
The width of described conductor rope platform is slightly less than the diameter of twice steel rope; The height of conductor rope platform equals the Up Highway UHW of ground floor rope.
The degree of depth of described conductor rope groove II is 1/20th of wirerope diameter; The height of conductor rope groove II is a little more than the line of centers of third layer rope.
The invention has the beneficial effects as follows:
1, on the reel of car spiral drum slot, storage grooving and conductor rope groove I is utilized to regulate steel rope to coil the second layer smoothly by ground floor.Conductor rope platform and conductor rope groove II is utilized to regulate steel rope to coil third layer smoothly by the second layer.Efficiently solve disorder cable problem.
2, the reel manufacture 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 save cost to a great extent.
3, store up grooving, conductor rope groove and conductor rope platform rational in infrastructure, manufacture craft is simple, and cost is low, is convenient to promote the use of.

Detailed description of the invention
As shown in drawings: a kind of hoister in large tonnage regulates the reel of flake down function automatically with having, it is made up of reel 10, first terminal block rope wall 8, end gear rope wall 1 and rope wedge hole 9.Described reel 10 is round tube, the periphery of round tube makes grooving 7, and described grooving 7 is car spiral drum slot.Described first terminal block rope wall 8 and end gear rope wall 1 are fixed at the two ends of reel 10, and reel 10 has rope wedge hole 9 near first terminal block rope wall 8 place.It is characterized in that: keep off at reel 10 and end wall 1 junction of restrict and makes and store up grooving 2, keep off on wall 1 inwall of restricting making conductor rope groove I 1-1 at end, store up the joint portion arc transition of grooving 2 and conductor rope groove I 1-1.Make conductor rope platform 6 in reel 10 and first terminal block rope wall 8 junction, first terminal block rope wall 8 inwall makes 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 third layer rope 4
As shown in drawings: described grooving 7 is car spiral drum slot, and reel manufacturing process first casts out drum blank, and then realized by machinework.The manufacture of Casting Parts blank is simple, is easy to control, and the finished product accuracy realized by machinework is good, and efficiency is high, and integrated cost is low.
As shown in drawings: during use, steel wire rope head is fixed on rope wedge hole 9, steel rope enters first grooving 7 of just terminal block rope wall 8 one end by rope outlet, along with the rotation of reel 10, steel wire disk in all groovings 7, when after steel wire disk to last grooving 7, enter storage grooving 2, because the length of storing up grooving 2 is the diameter of 2 to 2.5 times of steel ropes, two steel ropes in storage grooving 2 are no longer fettered, can according to stressing conditions free adjustment position.
Steel rope by ground floor in the change rope process of the second layer, ground floor steel rope is subject to the pressure of second layer steel rope, in storage grooving 2 and conductor rope groove I 1-1, freely adjust position, give second layer steel rope antagonistic force simultaneously, allow steel rope become rope smoothly to the second layer.
When after second layer steel wire disk to last grooving 7, enter conductor rope platform 6, the height due to conductor rope platform 6 equals the Up Highway UHW of ground floor rope 3.Steel rope can according to stressing conditions free adjustment position at conductor rope platform 6 place.
Steel rope by the second layer in the change rope process of third layer, the pressure that second layer steel rope is subject to third layer steel rope freely adjusts position in conductor rope platform 6 and conductor rope groove II 8-1, give third layer steel rope antagonistic force simultaneously, allow steel rope become rope smoothly to third layer.So can realize the smooth flake down of steel rope, avoid disorder cable phenomenon, reduce steel rope abrasion, thus reach the object of prolonging service life of steel wire.
