Description

Cable pairing device

The utility model belongs to the plant equipment of making telecommunication cable.

Pairing device is one of capital equipment during the incity telephone cable produces, twist right purpose, it is the induction that is used for reducing between cable pair, long-term next, the manufacturing of pairing device all is to continue to use traditional custom design, in the use, inefficiency, frictional resistance is big, and fault is many, makes strand not catch up with the development that modernized cable streamline is produced to work, have to remedy the deficiency of production with adding way that machine adds the people, obviously this is a kind of passive practice, so caused the attention of domestic and international relevant technologies brainstrust, many producers have done various discussions and design to the improvement of pairing device.

In 1985 second phase, Shanghai publication " electric wire " magazine is write and has been introduced Sweden Karma ladder gram (KABMATK) cable machinery manufactory in " novel cable pairing device " literary composition, the nearest N500 type pairing device of producing, it is a kind of novel pairing device of external development, these machine characteristics, twist arc shape and change sphere into, strand bowstave material changes reinforced plastic glass fibre into, the core shift cradle body, change actinobacillus wheel into and tilt to put cradle, though these improvement make the strand bow alleviate weight, the centrifugal force when making the rotation of strand bow, frictional resistance has obtained to a certain degree improving, but does not thoroughly eradicate the various drawbacks that produce because of the rotation of strand bow yet.

In 1985, third and fourth phase " post and telecommunications industrial technology " magazine is write in " (force analysis of cable pairing device strand bow " literary composition and has been introduced the MY24-20S-24 type pairing device that U.S. EDMANDS company makes, this pairing device design characteristic mainly is: make the arc shape of strand change ellipse garden into, strand bowstave material changes fiberglass into---and glass fiber reinforced epoxy resin, strand bow section configuration changes rectangle, rhombus into.Though these improvement have solved some problems on original basis; but have in the literary composition admit that problems such as frictional resistance that " this pairing device also exists strand head member frequent breakage; frequent shutdown maintenance, loses a large amount of production man-hours " pair twist bow high speed rotating produces, the sound, noise, parts temperature rise still remain to improve, improve.

On May 12nd, 1, " the magnetic control vertical bow type cable pairing device " of having been granted patent by State Patent Office of my design, the patent No. 286200342, the design feature of this pairing device: replaced traditional eccentric cradle body with magnetic control means, change the strand bow and be vertical rotating, the strand bow is shaped as local garden tube, and this design is compared with other pairing devices, had largely and broken through, made operating efficiency obtain large increase.Yet it does not break away from " strand bow " this key critical piece yet.Therefore, the various drawbacks that produce owing to strand bow high speed rotating are thoroughly eradicated so far as yet.

In sum, the design or the improvement of all pairing devices of introducing by various data, basic identical, all be the problem that exists round pairing device, inefficiency, frictional resistance is big, equipment fault is many, the difficulty of making, draw materials is improved design.And the basic reason that produces these problems all is the strand bow of pairing device, and the centrifugal force that produces during because of high speed rotating is caused.So the focus of everybody design all is again aspects such as the arc shape of strand that concentrates on pairing device, material, its result is again same, makes pairing device obtain different raising of degree or improvement, has not but made the drawback of pairing device obtain eradicating.

The purpose of this utility model: be in order to eradicate the drawback of all kinds of pairing devices of existing usefulness.Structurally done completely reform, fully phased out normally used strand bow, replaced that structure is simpler, more convenient operation, nothing bow pairing device that operating efficiency is higher, obtained desirable effect through regular period on probation.

Introduce below and do not have the bow pairing device.

Do not have the bow pairing device and mainly spend paired mechanism, then its twisted wire is kept well wheel by strand.

Its course of work is:from being seated on the actinobacillus wheel on the scratch diskette, involve single heart yearn respectively through traction, walking around the scratch diskette strand by a strand center along the strand wing spends in pairs, directly take turns to take-up and take turns through line concentration, finish whole strand to work, be not difficult to find out, be completely free of traditional approach here, need not twist bow, just can realize twisting and spend paired technical matters requirement.The utility model does not have the structure of bow pairing device, shown in accompanying drawing:strand wing (2) is fixed on the strand head (8), with the strand head, rotate along track (1) according to certain speed, the end points of strand wing (2) is equipped with assembly pulley (3), assembly pulley (3) is the heart yearn of dredging from actinobacillus wheel (6), is twisted to spend in pairs and takes turns to take-up through the line concentration wheel (5) on top.Actinobacillus wheel (6) is fixed on the support (9) of scratch diskette (7), and support (9) studs with the inertia that the infinite variable speed requirement and preventing when guaranteeing actinobacillus wheel (6) unwrapping wire line of bearing and dead-man's device (13) brings because of rotation.The bottom of scratch diskette (7) is in upper and lower one group of permanent magnet relative and that keep certain distance (11) and (12) of being equipped with of strand wing (2) rotational trajectory (1); Last permanent magnet (11) be fixed on scratch diskette (7) below, following permanent magnet (12) is fixed on the casing (10), scratch diskette (7) can rotate arbitrarily, but when work, scratch diskette (7) is because up and down permanent magnet (11) and (12) mutual suction can keep static relatively.When the flat strand wing (2) of profile during along track (1) high speed rotating, can be smoothly by the spatial joint clearance of last lower magnet (11) with (12) .Simultaneously can make the scratch diskette (7) can be manually arbitrarily angled at any time according to requirements of one's work again, casing (10) is that whole strand is spent paired casing, be again the protection safety cover of strand wing (2), 2.8 kilowatts of the rotary power of strand head (8) is by the motor of belt transmission from.

The utility model is compared its advantage with now general pairing device: 1, efficient height, usability is strong.Because of having taken down the strand bow, bend all drawbacks that rotation causes thereby eradicated because of strand, its speed no longer is subjected to the restriction of these drawbacks, line footpath, the specification right according to strand, selected velocity or lay have not only improved operating efficiency, and have increased the scope of application.2, improved the cable core quality.Because of having removed strand bow, thus removed heart yearn strand to the time, the frictionally damage that must be caused by the strand bow, the broken skin or the damage of having eradicated the core insulation layer---the cable potential risk has but been protected cable quality.3, simple in structure, easy to use.Because of having removed the strand bow, entire equipment is greatly simplified, reduced unnecessary link, make in the selection processing and manufacturing all more or less freely.Simultaneously, make coring circuit by moving towards simplification, having avoided shuttling back and forth makes operation more simple and convenient.4, equipment is sturdy and durable.Because of having taken down strand bow, eradicated the strand head and damaged, there is not the centrifugal force of a strand axially loaded, strand bow and because of these stressed drawbacks of bringing.For example parts temperature rise, damage, the sound, noise and various frictional resistance etc. have improved useful life greatly.

Annotate:

The utility model has three kinds of laies: 1. 60mm; 2. 75mm; 3. 90mm.

Six kinds of speed: 1. 150M/rpm; 2. 120M/rpm; 3. 4. 96M/rpm of 108M/rpm; 5. 90M/rpm; 6. 70M/rpm.
