A kind of steel wire rope spiral knot joint method

technical field

The invention relates to the technical field of machinery, in particular to a steel wire rope spiral knot joint method.

technical background

In order to adapt to the development trend of modern population to urban filling, to facilitate and meet the living needs of urban population living buildings, and to better adapt to and complete the task of transporting up and down modern high-rise buildings, people have been researching and inventing various types of high-performance elevators.

Patent Publication No. CN104555661A Safe, high-efficiency, energy-saving elevator and manufacturing method, in the manufacturing implementation, involves the use of chain ropes as power transmission components, and steel rope rings are the basic material components to be selected.

The chain rope is the core component of the above-mentioned new high-performance elevator, and the high-quality steel rope ring is the basic component of the core component of the chain rope. The core technology component is to make the steel wire rope into a high-quality anti-stripping, stable circumference value, small dispersion coefficient, high joint strength, especially the spiral knot steel rope ring with a very small dispersion coefficient of the joint strength is the above-mentioned high-performance elevator. It can be realized and the key to the success of mechanical manufacturing.

However, the steel wire rope is different from the traditional soft rope. It is made of steel. Although it has a large bearing capacity, the steel wire rope has great elasticity, rigidity, and rope diameter. Big, maybe even impossible.

Contents of the invention

In order to solve the above problems, the present invention provides a steel wire rope spiral knot joint method, including the use of various lock joints and embedded wrapping joints for steel wire ropes. There are mainly the following four methods:

1. Discharge the two steel ropes between the lock clip seats, tighten the screw nut, connect the clip seats, and squeeze and lock the steel wire ropes by the clip seats to achieve the purpose of the joint;

2. Use a soft metal cylindrical tube to cover the two steel ropes, and then use a special mechanical pressure head to squeeze the metal tube. The metal tube is squeezed and embedded with the surface of the steel wire rope, and the steel wire rope is locked to achieve the purpose of the joint;

3. Tapered lock joint: the surface of the inner cone is made of soft metal, the steel wire rope is evenly distributed around the surface of the inner cone, the outer cone is sleeved on the outside of the steel wire rope evenly distributed in a conical shape, the inner and outer cones are tightened, the steel wire rope and the surface of the inner cone are soft Metal interlocking, clamping and self-locking with the outer cone to achieve the purpose of the joint;

4. Long rope end insertion method joint: the relatively long and thin steel wire rope is repeatedly twisted and wound into a multi-strand steel wire rope ring. When the final joint is made, the end of the steel wire rope head and tail with a value dozens of times the diameter and length of the long steel wire rope is inserted into the multi-strand steel rope ring. Between them, relying on the embedded friction of each steel wire rope against the thin rope at the end, the purpose of the joint is achieved.

The spiral knot joint method of the steel wire rope of the present invention is characterized in that: the spiral knot includes a steel rope head processed at both ends of a steel wire rope, two sets of spiral coils connected with it, and a steel rope body connected with the spiral coils;

After the two groups of helical rope loops are turned inwardly by 180° along the connection between them and the steel rope body, the helical circles are made to take the other steel rope body rope line as the axis, and the helical circles are swung to connect the other steel rope body rope. The line is converted from the outside of the circle to the inside of the circle;

According to the direction of rope head to rope head, move the helical circle along two parallel or intersecting steel rope bodies to make them close to each other, and the steel rope heads pass through another helical circle until the two sets of helical circles are close together;

In the middle between the two spiral circles, use a special pliers tool to clamp the roots of the two steel rope heads, arrange the two sets of spiral circles, make the spiral circles change from large to small, and from small to tight, and then clamp them when they are tighter The left and right ends of the spiral circle keep the two sets of spiral circles tight and not loose;

First pull the steel rope body, and then pull the steel rope head, so that the spiral ring, load-bearing steel rope body, and steel rope head are all tensioned to form two spiral ring locking areas, which rely on and support each other. A perfectly compliant, spiral knot with excellent shedding resistance.

When tension is applied to the load-bearing steel rope bodies at both ends of the knot, the load-bearing steel rope bodies first pass through the core axis direction of the helical ring locking area, and pass through the middle to apply tension to the other helical ring locking area, so that the two ends of the knot The helical circle outside the locking area of the first helical circle pulls back and compresses its own helical rope circle towards the middle, and the steel rope heads tightly locked by the other steel rope circle support their own helical rope circle tightly outward respectively. The force of one inside and one outside makes the two sets of helical coils locked, and the locked two sets of helical coils tightly lock the load-bearing steel rope body and steel rope head in the circles, thereby forming a complete interlocking, Chain spiral knot joints, due to the greater elasticity and rigidity of the steel rope, when the load-bearing steel rope body loses the external tension, due to the strong self-locking and interlocking effect between the spiral ring and the rope head, the mutual dependence in the knot is stable. The locked state will not change. Therefore, the spiral knot is also called a rope joint that is difficult to untie after locking. For the working conditions under normal stress such as large-scale construction in the field, sightseeing cars and high-efficiency energy-saving elevators, the spiral knot type wire rope joint is used. , has the advantage of being safer and more reliable.

The length L of the inserted steel rope ends is a spiral The product of the number of turns n and the diameter d of the steel wire rope is added to the length b of the tapered buckle of the rope head (L=n*d+b), and the diameter of the selected coil spring shaft is selected as about 1.5 times the straight diameter of the steel wire rope;

6) Preparing for the pre-processing of the spiral coil: manually ratchet the lever, turn the coil shaft roller, and make the coil shaft roller rotate a few times to reach the number of turns of the spiral coil to be wound or slightly exceed;

7) Clamp the coil spring splint, and the distance between the two splints is slightly larger than the product value of the spiral ring n and the diameter d of the wire rope;

8) Turn on the hydraulic cylinder, the rope storage roller moves together with the slider seat, so that the wire rope is gradually tensioned, and the wire rope is tightened strongly, stop pulling within a proper time and use a wooden hammer to hit, pull or hit again, repeat Carry out similar operations until the n-circle helical coil solid task that is rolled on the coil spring shaft is completed, and the helical coil semi-finished product is produced, as shown in Fig. 4;

9) Repeat 5) to 8) to produce in batches a plurality of steel wire rope semi-finished products with pre-processed helical coils;

Mechanical joint:

10) Clamp the steel rope bodies of the steel wire rope semi-finished products of the wound spiral rope circle in two pairs of tension rollers respectively;

11) Flip the spiral ropes at the two ends by 180° respectively, and turn the spiral rope to make it correspond to the steel rope body at the other end as the core line, and turn the steel rope body at the other end outside the spiral rope circle transformed into the helical coil;

12) Adjust the two pairs of tensioning rollers so that the two sets of helical rope loop steel wire ropes are close to each other, and the rope heads are interspersed with each other in the other rope loop steel wire rope loops, and grow an appropriate distance;

13) Use the steel rope head clamping pliers to clamp the root of the steel rope head in the middle of the spiral knot, and then use the special wrench for shrinking and tightening the spiral ring to shrink and tighten the spiral ring. Clamp the outer ends of the left and right spiral coils, the steel rope body and the steel rope head with the pliers. After checking that they are reliable, pull the steel rope bodies at both ends. After tightening, remove the special tool pliers;

14) Check again and repeatedly perform hydraulic pulling and locking, so that the steel rope body, steel rope head, and the spiral knots are tightly locked together, and the final shaping of the spiral knots is completed until a qualified spiral knot is tied. ;
