Description

Technical Field

[0001] The invention relates to the technical field of glass fiber ropes, in particular to a heat-resistant and aging-resistant glass fiber rope for cable materials. Background Art

[0002] Glass fiber is a high-strength, corrosion-resistant, and fire-resistant fiber material with certain insulation properties. It can protect cables and wires, so it is widely used in cable protection and other fields.

[0003] A heat-resistant and aging-resistant glass fiber rope for cable material described in the patent application with announcement number CN209487174U relates to the field of cable technology. The heat-resistant and aging-resistant glass fiber rope for cable material comprises a rope core body, a glass fiber tube is installed on the outside of the rope core body, a silicone rubber layer is installed on the outside of the glass fiber tube, an insulating layer is fixedly connected to the outside of the silicone rubber layer, and positioning hinges arranged in a circumferential array are installed on the outer surface of the rope core body, and a connecting plate is installed in the middle of the outer side of the positioning hinge;

[0004] At present, when glass fiber rope is used to wrap wires, glass fiber is usually combined with other materials (such as plastic, rubber, etc.) to form a composite insulation layer. The heat-resistant and aging-resistant glass fiber rope with a composite insulation layer is formed. However, when the wires wrapped with glass fiber rope are used in factory buildings, due to their poor wear resistance, the equipment is moved back and forth, causing friction on the lines, which is prone to damage and breakage, causing certain safety hazards. In addition, a large number of heavy objects are piled in the factory building. Once they fall over, they will press on the glass fiber rope wires, which may seriously cause short circuits and fires.

The interior of the telescopic bag is a sealed space. The telescopic bag is used to wrap the composite fiberglass rope.

[0010] Preferably, air is provided in the sealed space inside the telescopic bag, and the sealed space inside the telescopic bag can be communicated with the outside of the telescopic bag through an air hole, and the air hole is used to communicate the air inside and outside the telescopic bag.

[0011] Preferably, a pulling mechanism is provided inside the telescopic bag, and the pulling mechanism includes a push rod, one end of the push rod is fixedly connected to the inner wall of the telescopic bag, and the other end of the push rod is fixedly connected to the outer wall of the push ring. One side of the push ring is connected to the slip ring through a pull rod, and a pull rope is provided on the outer wall of the slip ring.

[0012] Preferably, one side of the push ring is fixedly connected to one end of the pull rod, a groove is provided on the inner wall of the push ring, the other end of the pull rod passes through the groove and is fixedly connected to one side of the slip ring, and the inner wall of the push ring is slidably connected to the outer wall of the long sleeve.

[0013] Preferably, the groove allows the slide slot to pass through it, and the push rod is made of hard rubber. The push rod is used to be squeezed by the telescopic bag to play the role of pushing the push ring.

[0014] Preferably, a slide groove is provided on the inner wall of the short sleeve, a stopper is provided on one end of the slide groove away from the telescopic bag, the inner wall of the slip ring is slidably connected to the outer wall of the short sleeve through the slide groove, and the stopper serves to limit the slip ring and prevent it from falling out of the short sleeve.

[0015] Preferably, a slider is fixedly connected to the inner wall of the slip ring, the slip ring is slidably connected to the inner wall of the slide groove through the slider, one end of the pull rod is fixedly connected to one side of the slip ring through the slider, and the slider can be blocked by a block to play a limiting role.

[0016] Preferably, the number of push rings inside a set of protection mechanisms is two, and the grooves in the two opposing push rings are distributed at an angle of 90 degrees to each other.

[0017] The present invention provides a heat-resistant and aging-resistant glass fiber rope for cable materials. It has the following beneficial effects:

[0018] 1. The present invention provides a protective mechanism. Since a long sleeve and a telescopic bag are provided on the outside of the composite glass fiber rope, when the composite glass fiber rope is dragged, it will contact the ground through the external telescopic bag and be dragged and tightened. At the same time, when the composite glass fiber rope is dragged and straightened, the composite glass fiber rope between each telescopic bag will be lifted up due to the straightening and separated from the friction with the ground, so that when the composite glass fiber rope is separated, the outer wall and the ground will not be broken due to friction, which not only maintains its excellent insulation and compression and tensile resistance, but also avoids the problem of easy wear of the glass fiber material of the composite glass fiber rope.

[0019] 2. The present invention sets a protective mechanism. In the factory processing, it is easy to cause the accident of dumping various large materials such as plates due to processing. Once the composite glass fiber rope is pressed by plate-shaped and block-shaped heavy objects, the telescopic bag can first support the pressed plate-shaped heavy objects, thereby protecting the composite glass fiber rope and effectively preventing the composite glass fiber rope from being directly pressed, causing the copper wire of the internal wire to be squeezed and broken and catch fire.

[0020] 3. The present invention provides a protective mechanism. Once the composite glass fiber rope is pressed by a plate-shaped or block-shaped heavy object, the telescopic bag will protect the composite glass fiber rope, effectively preventing the composite glass fiber rope from being directly pressed, which may cause the copper wire of the internal wire to be squeezed, broken and caught fire, etc. The telescopic bag can be deformed to unload the force of the falling heavy object, as well as buffer and protect the composite glass fiber rope. The telescopic bag can evenly buffer the load-bearing object, which not only protects the composite glass fiber rope, but also prevents the telescopic bag from breaking and piercing the composite glass fiber rope, causing damage. This achieves comprehensive protection of the composite glass fiber rope and the internal circuit, prevents them from being damaged, and reduces safety accidents.

[0021] 4. The present invention sets up a protective mechanism. Since the force exerted when a heavy object falls is relatively large, not only can the surrounding telescopic bags be pulled toward the heavy object, but also the large kinetic energy can be used to pull the telescopic bags and quickly slide them to the place through inertia, thereby concentrating multiple telescopic bags as much as possible to resist the pressure of the plate-like heavy object above, and to reduce the damage caused by the compression of the composite glass fiber rope and the internal wires as much as possible, thereby avoiding some serious accidental short circuit fire problems that often occur in factories.

[0022] 5. The present invention provides a protection mechanism. When problems arise with the wires inside the composite glass fiber rope after long-term use and the wires need to be pulled out for maintenance, the telescopic bag on the outer wall of the composite glass fiber rope can use its convex shape to replace the friction between the composite glass fiber rope and the inside of the wire tube, thereby avoiding the problem of wear and tear caused by continuous friction between the composite glass fiber rope and the wire tube when the composite glass fiber rope is pulled and passes through a large curved wire tube. This can protect the composite glass fiber rope and reduce friction as much as possible when the wires are pulled out during maintenance in the wire tube.

[0023] 6. The present invention provides a pulling mechanism. If a jamming situation that makes pulling difficult is encountered, the telescopic bag can be pressed and pulled out, so that the internal push ring pulls the long sleeve in the wire tube, thereby properly controlling the pulling force to prevent excessive manual pulling force from causing breakage and wear. By continuously pressing the telescopic bag, the short sleeve in the wire tube and the telescopic bag can be shaken back and forth, and the stuck part in the wire tube can be vibrated out as much as possible through the shaking, thereby facilitating the pulling and maintenance of the composite fiberglass rope.

[0034] In the figure: 1 composite glass fiber rope, 2 protection mechanism, 201 long sleeve, 202 short sleeve, 203 telescopic bag, 204 air hole, 3 pulling mechanism, 301 push rod, 302 push ring, 303 pull rod, 304 slip ring, 305 pull rope, 306 groove, 307 slide groove. DETAILED DESCRIPTION

[0035] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a heat-resistant and aging-resistant glass fiber rope for cable material, comprising a composite glass fiber rope 1, wherein the composite glass fiber rope 1 is provided with electric wires inside, and the composite glass fiber rope 1 is provided with a protective mechanism 2 outside;

[0036] Protection mechanism 2 includes:

[0037] A long sleeve 201, the inner wall of the long sleeve 201 is fixedly connected to the outer wall of the composite glass fiber rope 1, the long sleeve 201 is a circular sleeve structure, the outer wall of the long sleeve 201 is fixedly connected to the short sleeve 202, the long sleeve 201 is used to connect the short sleeve 202 and the composite glass fiber rope 1, the short sleeve 202 is a circular sleeve structure;

[0038] The telescopic bag 203 is made of hard rubber and is an elliptical sleeve structure. The inner wall of the telescopic bag 203 is fixedly connected to the outer wall of the short sleeve 202. The interior of the telescopic bag 203 is a sealed space. The telescopic bag 203 is used to wrap the composite glass fiber rope 1.

[0039] When the composite glass fiber rope 1 is used in factory equipment and wrapped around electric wires as an insulating material, after the composite glass fiber rope 1 is connected to the equipment, when the construction equipment is moved back and forth and dragged, the composite glass fiber rope 1 will be stretched straight on the ground and pulled to cause friction. However, since the composite glass fiber rope 1 is provided with a long sleeve 201 and a telescopic bag 203 on the outside, the diameter of the center of the telescopic bag 203 is much larger than the diameter of the composite glass fiber rope 1, so when the composite glass fiber rope 1 is dragged, it will contact the ground through the external telescopic bag 203 and be dragged and tightened;

[0040] At the same time, when the composite glass fiber rope 1 is pulled and stretched, the composite glass fiber rope 1 between each telescopic bag 203 will be lifted due to the stretching and separated from the friction with the ground, so that when the composite glass fiber rope 1 is separated, the outer wall and the ground will not be broken due to friction, which not only maintains its excellent insulation and compression and tensile resistance, but also avoids the problem of the glass fiber material of the composite glass fiber rope 1 being easily worn;

[0041] The outer wall of the telescopic capsule 203 is coated with a coating that can make the surface smooth, so as to ensure that the telescopic capsule 203 can reduce the friction with other objects as much as possible when sliding, so that the movement friction is fast;

[0042] Example 2: Please refer to Figure 1-7 On the basis of the first embodiment, the present invention provides a technical solution: air is provided in the sealed space inside the telescopic bag 203, and the sealed space inside the telescopic bag 203 can be communicated with the outside of the telescopic bag 203 through the air hole 204, and the air hole 204 is used to make the air inside and outside the telescopic bag 203 communicate with each other;

[0043] In factory processing, it is easy for various large materials such as plates to fall down unexpectedly due to processing, so that large plates and blocks will directly press on the wires when they fall down, causing the wires to short-circuit and catch fire. Once the composite glass fiber rope 1 is pressed by a plate-shaped or block-shaped heavy object, the telescopic bag 203 can first support the pressed plate-shaped heavy object, thereby protecting the composite glass fiber rope 1 and effectively preventing the composite glass fiber rope 1 from being directly pressed, causing the copper wire of the internal wire to be squeezed, broken, and catch fire.

[0044] At the same time, an air hole 204 is provided on the telescopic bag 203, and the interior of the telescopic bag 203 is a closed space. Therefore, when the telescopic bag 203 is pressed, part of the air inside is instantly discharged through the air hole 204, but the subsequent air will begin to be exhausted slowly due to the limitation of the small aperture of the air hole 204, so that the force unloading of the falling heavy object and the buffering and protection of the composite glass fiber rope 1 are completed through the deformable mode of the telescopic bag 203. The telescopic bag 203 uniformly buffers the load-bearing object and uniformly transmits the force outward, thereby avoiding the problem of the telescopic bag 203 being directly broken and fractured by the pressure of the heavy object, protecting the composite glass fiber rope 1 while preventing the telescopic bag 203 from breaking and piercing into the composite glass fiber rope 1 to cause damage, thereby realizing comprehensive protection of the composite glass fiber rope 1 and the internal circuit to prevent them from being damaged and reduce safety accidents;

[0045] Example 3: Please refer to Figure 1-10 On the basis of the first and second embodiments, the present invention provides a technical solution: a pulling mechanism 3 is arranged inside the telescopic bag 203, and the pulling mechanism 3 includes a push rod 301, one end of the push rod 301 is fixedly connected to the inner wall of the telescopic bag 203, and the other end of the push rod 301 is fixedly connected to the outer wall of the push ring 302, one side of the push ring 302 is connected to the slip ring 304 through the pull rod 303, and the outer wall of the slip ring 304 is provided with a pull rope 305.

[0046] One side of the push ring 302 is fixedly connected to one end of the pull rod 303 , a groove 306 is provided on the inner wall of the push ring 302 , the other end of the pull rod 303 passes through the groove 306 and is fixedly connected to one side of the slip ring 304 , and the inner wall of the push ring 302 is slidably connected to the outer wall of the long sleeve 201 .

[0047] The groove 306 allows the slide slot 307 to pass therethrough. The push rod 301 is made of hard rubber. The push rod 301 is used to be squeezed by the telescopic bag 203 to push the push ring 302 .

[0048] A slide groove 307 is provided on the inner wall of the short sleeve 202, and a stopper is provided on the end of the slide groove 307 away from the telescopic bag 203. The inner wall of the slip ring 304 is slidably connected to the outer wall of the short sleeve 202 through the slide groove 307, and the stopper limits the slip ring 304 to prevent it from falling out of the short sleeve 202.

[0049] A slider is fixedly connected to the inner wall of the slip ring 304, and the slip ring 304 is slidably connected to the inner wall of the slide groove 307 through the slider. One end of the pull rod 303 is fixedly connected to one side of the slip ring 304 through the slider, and the slider can be blocked by the block to play a limiting role.

[0050] There are two push rings 302 in a set of protection mechanisms 2, and the grooves 306 in the two opposing push rings 302 are staggered by 90 degrees.

[0051] When the telescopic bag 203 is suddenly pressed by gravity, the instantaneous gravity will cause the air inside the telescopic bag 203 to be quickly discharged through the air hole 204, and the telescopic bag 203 will be quickly contracted. At this time, when the telescopic bag 203 is pressed and contracted, the push rod 301 inside will be pressed, and the push rod 301 is made of harder rubber material, and the push rod 301 is connected between the push ring 302 and the telescopic bag 203 in an inclined state, so that when the push rod 301 is pushed inward instantly, it will be pushed onto the push ring 302 through its elastic deformation and its thrust;

[0052] The push ring 302 is sleeved on the outer wall of the long sleeve 201, and the two push rings 302 in the middle of a telescopic bag 203 are instantly pushed away from each other by the push rod 301, and the pull rod 303 connected to the push ring 302 pulls the slip ring 304 and the pull rope 305, so that the pull rope 305 is connected to the slip ring 304 on another telescopic bag 203 not far away and is instantly pulled to the position of the telescopic bag 203 under pressure here;

[0053] Since the force of the heavy object falling down is relatively large, not only can the surrounding telescopic capsules 203 be pulled toward the heavy object, but also the large kinetic energy can be used to pull the telescopic capsules 203 and quickly slide to the location through their inertia, so as to achieve the concentration of multiple telescopic capsules 203 as much as possible to resist the pressure of the plate-like heavy object above, and to reduce the damage caused by the compression of the composite glass fiber rope 1 and the internal wires as much as possible, so as to avoid some serious accidental short circuit fire problems that often occur in factories;

[0054] When the surrounding bellows 203 move toward the bellows 203, since the air inside the bellows 203 cannot be discharged instantly through the air hole 204, the bellows 203 will still maintain the slow discharge of subsequent air after being pressed instantly, thereby giving a certain space under the plate-like weight, so that other bellows 203 can approach and realize the joint force effect on the weight;

[0055] Since the two push rings 302 are away from each other, the push ring 302 pulls the pull rod 303, and the pull rod 303 passes through the groove 306 in the other push ring 302 and the slide groove 307 in the push ring 302 to pull the slip ring 304. Therefore, when the two push rings 302 are squeezed outward instantly, the pull rod 303 accurately and quickly pulls the slip ring 304 on the short sleeve 202 to quickly slide toward the center of the telescopic bag 203, and then pulls the other slip ring 304, the short sleeve 202, and the telescopic bag 203 to move there through the pull rope 305;

[0056] At the same time, the composite glass fiber rope 1 can still be used for the threading of wire tubes. When the composite glass fiber rope 1 passes through the wall cloth and the wire tubes on the ground, once the wires inside the composite glass fiber rope 1 have problems after being used for a long time and need to be pulled out for maintenance, when the composite glass fiber rope 1 is pulled, since the wires in the wire tube are often arranged in a criss-cross pattern, the composite glass fiber rope 1 will encounter an arc position in the wire tube when it is pulled. At this time, the telescopic bag 203 on the outer wall of the composite glass fiber rope 1 will still use its convex shape to replace the friction between the composite glass fiber rope 1 and the wire tube, so as to avoid the problem of wear caused by continuous friction between the composite glass fiber rope 1 and the wire tube when the composite glass fiber rope 1 passes through a large curved wire tube when it is pulled, so as to protect the composite glass fiber rope 1 and reduce friction as much as possible when the wires are pulled out in the wire tube.

[0057] When inspecting and drawing the composite glass fiber rope 1, if a jamming situation that is difficult to draw is encountered, it indicates that there may be a relatively curved corner problem in the line. At this time, if the composite glass fiber rope 1 is pulled hard, the friction of the composite glass fiber rope 1 will increase or even break. At this time, the telescopic bag 203 can be pressed and pulled out, so that the internal push ring 302 can pull the slip ring 304, the short sleeve 202 and the long sleeve 201 in the wire tube through the pull rod 303, the slip ring 304 and the pull rope 305, so that the pulling force can be properly controlled to prevent the manual pulling force from being too large and causing breakage and wear. By continuously pressing the telescopic bag 203, the pull rope 305 can pull the other short sleeve 202 and the telescopic bag 203 to shake back and forth, and the shaking can make the stuck part in the wire tube vibrate and detach as much as possible, so as to facilitate the pulling and inspection of the composite glass fiber rope 1.

[0058] The bellows 203 is made of a harder rubber material with a greater elastic force. After the bellows 203 is deformed, it can expand with its own elastic force and reset itself, so that the push rod 301 and the push ring 302 and other structures can be pulled back synchronously.

[0059] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
