Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cables, in particular to a halogen-free ceramic bead insulation water-blocking fire-resistant cable and a production system thereof. BACKGROUND

[0002] In modern building, transportation hub and large public facilities construction, the fire resistance performance of cables is increasingly demanding. At present, fire-resistant cables on the market are mainly divided into two types: fire-resistant flexible mineral insulated cables and rigid mineral insulated cables. Among them, the fire-resistant flexible mineral insulated cable uses mica tape as insulation, and its fire resistance test temperature can reach 750 DEG C, which can meet the fireproofing needs of general scenarios; while the rigid mineral insulated cable uses magnesium oxide filled between the conductor and the protective copper sealing sleeve as insulation, with a high fire resistance test temperature of 950 DEG C - 1000 DEG C, it becomes the first choice for places with extremely high fire performance requirements such as high-rise buildings, stadiums, large entertainment parks, airports, etc.

[0003] However, the rigid mineral insulated cable has obvious drawbacks in production and application process. The powder-like magnesium oxide used in the insulation material of the cable is easy to diffuse into the environment during cable processing, causing dust pollution, which not only affects the working environment of the production workshop, but also may harm the health of the operators. At the same time, when the density of magnesium oxide powder in the air reaches a certain value, there is a safety hazard of dust explosion, which greatly limits the safety and environmental protection of the production process. In addition, with the continuous improvement of people's awareness of fire safety and environmental protection, the traditional cable may release toxic gases when a fire occurs, which poses a serious threat to personnel evacuation and rescue.

[0004] Therefore, it is urgent to develop a new type of cable that can not only meet the high fire resistance performance requirements, but also not produce toxic gases in case of fire, and has good water-blocking performance, and the production process is more environmentally friendly and safe. Based on this, a halogen-free ceramic bead insulation water-blocking fire-resistant cable and a production system thereof are proposed to fill the market gap and promote the upgrading and development of fire-resistant cable technology.

[0005] The purpose of the present application is to provide a halogen-free ceramic bead insulation water-blocking fire-resistant cable and a production system thereof, which can not only meet the high fire resistance performance requirements, but also not produce toxic gases in case of fire, and has good water-blocking performance.

DETAILED DESCRIPTION

[0043] In order to make the object, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application in the text are based on the drawings of the present application, which are not specific limitations on the present application.

[0044] As shown in Figure 19 A halogen-free ceramic bead insulation water-resistant fireproof cable comprises: a solid conductor 20 made of a copper bar as a conductive core of the cable; ceramic insulation beads 21 filled between the solid conductor 20 and a copper braid sealing sleeve 22, the ceramic insulation beads 21 are coated with talcum powder on the front surface before filling, so that the ceramic insulation beads 21 can slide between the conductor and the sealing sleeve to avoid the ceramic beads from breaking when the cable is bent; the copper braid sealing sleeve 22 is formed by longitudinally wrapping a copper strip and argon arc welding and jointing, and a plurality of vent holes 23 are arranged on the surface of the copper strip; a water-blocking tape 24 is spirally wrapped outside the copper braid sealing sleeve 22, the water-blocking material of which expands rapidly when wet or in contact with water to block the cable passage; a halogen-free flame-retardant outer sheath 25 is extruded and wrapped outside the water-blocking tape 24 to protect the cable and not release toxic halogen acid gas in case of fire; and a cable sealing plug made of the same material as the ceramic insulation beads 21 is used to block the cable end to prevent the insulation beads from falling off.

[0045] It should be noted that the entire cable is composed of the solid conductor 20, the ceramic insulation beads 21, the copper braid sealing sleeve 22, the water-blocking tape 24 and the halogen-free flame-retardant outer sheath 25, wherein the solid conductor 20 is made of a copper bar, a layer of copper braid sealing sleeve 22 is sleeved outside the solid conductor 20, and a layer of ceramic insulation beads 21 is filled between the solid conductor 20 and the copper braid sealing sleeve 22, which can achieve fireproof effect, and a vent hole with a diameter of 1.5 mm is punched every 30 mm on the copper braid sealing sleeve 22, which functions to release the expanded air between the ceramic beads through the vent hole in case of fire.

[0046] It should be further noted that the ceramic insulation beads 21 are used instead of powdered mineral insulation materials such as magnesium oxide, which has the advantage of greatly avoiding the influence of powdered substances on the working environment during cable processing, and the ceramic bead insulation material is widely available, which can be obtained by sintering of building ceramic clay, or by recycling of waste ceramic chips and waste glass, etc., and the manufacturing cost of the insulation beads is about 20% lower than that of magnesium oxide, which not only reduces production cost, but also is environmentally friendly.

[0047] Further, the ceramic insulation beads 21 are filled with talc powder before filling to make them have sliding property between the conductor and the sealing copper sleeve, so that the ceramic beads are not easily broken when the cable is bent. A water-blocking tape is wrapped around the outer copper tape of the cable. When the cable is wet due to normal operation or is sprayed with fire-fighting water in case of fire, the water-blocking material attached to the water-blocking tape expands rapidly to block the wet or water flow channel of the cable. The outer sheath 25 of the cable is halogen-free and flame-retardant, which not only has insulation effect, but also does not release toxic halogen acid gas in case of fire.

[0048] In particular, in the manufacturing process of the cable, another technical solution is that the conductive core can be a single-strand twisted conductor, which has softness and can increase the bending function of the conductor. The flat copper sealing sleeve 22 can be a corrugated copper sealing sleeve. The application mode of the corrugated copper sealing sleeve 6 is longitudinal wrapping of ordinary copper tape, butt joint welding by argon arc welding, and then rolling by a roller to form a depth of about 2mm of corrugation. The copper tape with corrugation is punched with an exhaust hole with a diameter of 1.5mm every 30mm before longitudinal wrapping. When the cable encounters high-temperature environment such as fire, the air between the ceramic insulation beads expands due to heat, and the expanded gas can be released directionally through the exhaust hole to avoid the rupture of the copper sealing sleeve due to high internal pressure, thereby maintaining the integrity of the cable structure and gaining valuable time for fire-fighting rescue.

[0049] As Figures 1-12As shown, a production system of a halogen-free ceramic bead insulation water-resistant fire-resistant cable includes a first frame body 1, a second frame body 11, a first guide mechanism 2, a second guide mechanism 3, an insulation bead introduction mechanism 5, a copper wrapping mechanism 15, and a vibration dispersion mechanism 17. The first guide mechanism 2 is arranged on the receiving support of the first frame body 1 and is used for guiding the copper strip. The second guide mechanism 3 is arranged on the receiving support of the first frame body 1 and is used for guiding the copper bar. The insulation bead introduction mechanism 5 is arranged on the first support frame 14 on one side of the first frame body 1 and is used for guiding the ceramic insulation bead 21. The flat copper wrapping mechanism 15 is arranged inside the first frame body 1 and is used for longitudinally wrapping the copper strip to wrap the ceramic insulation bead 21 on the solid conductor 20. The vibration dispersion mechanism 17 is arranged inside the first frame body 1 and is used for vibrating the cable after longitudinal wrapping to disperse the ceramic insulation bead 21. The welding seam device 16 is arranged on the first frame body 1 and is used for welding the gap after longitudinal wrapping of the copper strip. The first guide mechanism 2 includes a first feeding frame 201, a first bearing seat 202, and a first material passing roller 203. The first feeding frame 201 is arranged in the rotating groove of the receiving support, and the bottom of the receiving support is provided with the first bearing seat 202 and the first material passing roller 203. The second guide mechanism 3 includes a second feeding frame 302, a connecting force arm 303, a second bearing seat 301, and a first guide wheel 304. The second feeding frame 302 is arranged on the receiving support through the second bearing seat 301, and one end of the second bearing seat 301 is provided with the connecting force arm 303. Two connecting force arms 303 are provided with a first rotating rod therebetween, and the first rotating rod is provided with the first guide wheel 304.

[0050] It should be noted that the production system of the cable is combined by multiple working mechanisms. The first guide mechanism 2 and the second guide mechanism 3 on the first frame body 1 are respectively used for guiding the copper strip and the copper bar to be synchronously introduced into the copper wrapping mechanism 15 to realize longitudinal wrapping of the copper strip. The copper strip is arranged on the first feeding frame 201 and is introduced into the copper wrapping mechanism 15 inside the first frame body 1 through the first material passing roller 203 and the third guide mechanism 13 to realize insulation bead filling and longitudinal wrapping operation.

[0051] It should be further noted that the copper rod is wound and placed on the second feeding frame 302, guided by the first guide wheel 304 and the third guide mechanism 13, and sent into the copper wrapping mechanism 15 to be introduced together with the copper strip, so as to wrap the copper strip on the copper rod.

[0052] As Figures 1-6As shown, the third guide mechanism 13 includes a first connecting support 1301, a first guide roller 1302, a second guide roller 1303, a third bearing seat 1304, a second rotating rod 1305, a third rotating rod 1306, and a second guide wheel 1307. The first connecting support 1301 is arranged on one side of the first frame body 1, and the first connecting support 1301 is symmetrically provided with the first guide roller 1302 and the second guide roller 1303 inside. The other side of the first connecting support 1301 is provided with the third bearing seat 1304, and the third bearing seat 1304 is symmetrically provided with the second rotating rod 1305 and the third rotating rod 1306 inside. The second rotating rod 1305 and the third rotating rod 1306 are provided with the second guide wheel 1307.

[0053] It should be noted that, in order to realize accurate guiding of the copper strip and the copper rod, the third guide mechanism 13 is integrated on the outside of the first frame body 1 to construct a double-roller cooperative guiding system. The first connecting support 1301 is used as a bearing base, and the first guide roller 1302 and the second guide roller 1303 are symmetrically arranged inside the first connecting support 1301 and are vertically staggered. The distance between the two roller shafts is accurately matched with the thickness of the copper strip to form a constraint conveying channel. During operation, the copper strip is stably conveyed in the vertical direction under the double action of the surface friction of the double rollers and the guide groove, and the lateral deviation and the snake-shaped walking are effectively inhibited. At the same time, by accurately controlling the roughness of the roller surface and the tension, it is ensured that there is no risk of scratching the surface of the copper strip. This guiding structure not only provides a stable machining reference surface for the subsequent laser puncher 4, but also significantly improves the punching positioning accuracy and hole consistency by reducing material shaking, and realizes the integration of feeding guiding and machining positioning.

[0054] It should be further noted that, in order to ensure accurate guiding of the copper rod during conveying, the second rotating rod 1305 and the third rotating rod 1306 are symmetrically arranged on the non-connected side of the first connecting support 1301. The top ends of the two rotating rods are both equipped with high-precision second guide wheels 1307. Through the three-point supporting guiding structure, a stable guiding constraint surface is formed. This design can effectively offset the lateral force generated during the conveying of the copper rod, avoid deviation and shaking, and realize stable and accurate guiding and conveying of the copper rod, thereby significantly improving the production efficiency and product quality.

[0055] As Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, the copper cladding mechanism 15 includes a second connecting support 1501, a third guide roller 1504, a pressing roller 1506, a fourth guide roller 1508, a fifth guide roller 1509, a first material passing table 1511, and a second material passing table 1512. The second connecting support 1501 is connected to the inside of the first frame body 1 through connecting grooves 1503 on both sides. The inside of the second connecting support 1501 is provided with the third guide roller 1504 and the pressing roller 1506, which are oppositely arranged. The copper strip is pressed to form a cladding state through the pressing roller 1506. The fourth guide roller 1508 and the fifth guide roller 1509 are symmetrically arranged directly below the third guide roller 1504, and are used for guiding the copper rod into the cladding cavity formed by the copper strip. The first material passing table 1511 and the second material passing table 1512 are arranged directly below the fourth guide roller 1508, and the inside of the first material passing table 1511 and the second material passing table 1512 is provided with a material passing hole 1513, so as to extrude the copper strip to form a sealing sleeve structure.

[0056] It should be noted that in the symmetrical layout of the second connecting support 1501, the third guide roller 1504 and the pressing roller 1506 constitute a first longitudinal wrapping group. After the copper strip is embedded in the guide groove in the inside of the third guide roller 1504, the pressing roller 1506 applies precise pressure to force the copper strip to curl into an arc shape. The arc-shaped copper strip continues to travel and is further shaped by a second longitudinal wrapping group, and finally forms a cylindrical flat copper sealing sleeve structure. At this time, the fourth guide roller 1508 and the fifth guide roller 1509 play a guiding role to accurately guide the copper rod into the sealing sleeve formed by the copper strip. Subsequently, the ceramic insulating beads 21 are uniformly filled into the gap between the copper rod and the copper sealing sleeve. The semi-finished cable filled is sequentially passed through the material passing hole 1513 of the first material passing table 1511 and the second material passing table 1512, and is finally sealed and formed into a regular round cable structure under the extrusion action of the through hole.

In this process, the dehumidification belt 717 can cover different circumferential parts of the cable in turn, cooperating with the idler roller 713 to drive the circulation of the dehumidification belt 717, realizing omnidirectional and uniform wiping and adsorption on the surface of the cable, effectively improving the dehumidification effect.

[0069] It needs to be explained that, in order to realize the automatic winding of the cable surface water-blocking tape 24, the winding mechanism 9 is arranged on the second frame body 11, and the precise winding operation of the water-blocking tape is completed through the gear transmission and the cooperation with the rotating structure.

[0071] It needs to be further explained that, in order to solve the problem that the cable water-blocking tape 24 is easy to loosen after winding, the compacting structure is additionally arranged on the fourth support frame 901 of the winding mechanism 9, the compacting operation is performed on the cable after winding through the compacting wheel 917, and the overall stability of the cable is improved.
