Abstract
The invention relates to a method for producing a large-diameter triangular strand wire rope. The method comprises the following steps: rolling a round strand into a triangular strand core through a core rolling machine; producing strands of a steel wire rope through a serial strand rope machine set, wherein the number of steel wire layers out of the triangular strand core is 2 or 3 and the total number, exclusive of the number of strand core steel wires, ranges from 39 to 81; and manufacturing strands into the steel wire rope by using a rope machine. The serial strand rope machine set is a three-serially-connected strand rope machine set or a four-serially-connected strand rope machine set; the three-serially-connected strand rope machine set is used for producing the strand of which the strand core is provided with 2 layers of steel wires outside; and the four-serially-connected strand rope machine set is used for producing the strand of which the strand core is provided with 3 layers of steel wires outside. In the method, the round strand is rolled into the triangular strand core and the size of the strand core and the number of steel wire ropes of the outside layer are reasonably selected, so that a qualified large-diameter triangular strand is produced in a continuous production mode by the serial stand wire rope set; and the process is reasonable and the requirement on quality is met.
Description
Technical field
The present invention relates to a kind of production method of major diameter steel wire rope.
Background technology
The production method of triangular strand wire rope thigh is that to produce section configuration with special-purpose strander be leg-of-mutton strand, then on rope-forming machine through special-purpose rotational forming device extruding, be twisted into steel wire rope.The triangular strand wire rope diameter that existing structure is produced can only be below 58mm, and the above triangular strand wire rope one of 60mm is not have suitable structure, and the 2nd, equipment does not possess production capacity.
Utilize existing structure to produce large-diameter triangular strand wire rope, just simply steel wire diameter in the thigh is amplified, this disadvantage that can bring is: steel wire diameter is too thick in strand, not easy to operate during production, and main be that safety assurance ability in use reduces, the flexibility variation, the steel wire rope fatigue performance reduces, and service life is short.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of large-diameter triangular strand wire rope, this method is rolled into triangle thigh core by justifying thigh, choose reasonable thigh core size and cover wire rope radical, by series connection strand unit one line quantity-produced mode, produce qualified large-diameter triangular strand, technology is reasonable, and quality meets the demands.
The present invention is achieved through the following technical solutions:
A kind of production method of large-diameter triangular strand wire rope, this method comprises the steps:
1) adopts and to roll the core machine and will justify thigh and be rolled into triangle thigh core;
2) pass through the thigh that series connection strand unit is produced steel wire rope; The steel wire number of plies of triangle thigh core outside is 2 layers or 3 layers, and the total radical of steel wire does not comprise a strand core wire radical in the 39-81 scope;
3) make steel wire rope by rope-forming machine again.
Described series connection strand unit is three string series connection strand units or four string series connection strand units; It is the thigh of 2 layers of steel wire that three string series connection strand units are used for producing a burst core outside; It is the thigh of 3 layers of steel wire that four string series connection strand units are used for producing a burst core outside.
The I-beam wheel number of described series connection strand unit is 57-121.
Described rolling is equipped with 2-5 group roll on the core machine, roll is contained on the rotary turnplate; Every group of roll comprises 2 or 3 active rolls, and roll pass is a triangle.
The rotating speed of described rotary turnplate is identical with the pitch dish rotating speed of series connection strand unit.
Compared with prior art, the invention has the beneficial effects as follows: adopt this method can produce the triangular strand wire rope that maximum gauge can reach 100mm, substitute the major diameter round-strand rope, improved the product use and received the order, satisfy user's instructions for use.

The specific embodiment
A kind of production method of large-diameter triangular strand wire rope, this method comprises the steps:
4) see Fig. 4-1, Fig. 4-2, adopt and to roll the core machine and will justify thigh and be rolled into triangle thigh core;
2) see Fig. 1-1, Fig. 1-2, the steel wire number of plies of triangle thigh core outside is 2 layers or 3 layers, and the total radical of steel wire does not comprise a strand core wire radical in the 39-81 scope; Produce the thigh of steel wire rope by series connection strand unit; Community of stock rope unit is three string series connection strand units or four string series connection strand units; It is the thigh of 2 layers of steel wire that three string series connection strand units are used for producing a burst core outside; Four string series connection strand units are used for producing the thigh (see figure 3) that burst core outside is 3 layers of steel wire.The number of the I-beam wheel of series connection strand unit is 57-121.
