Description

Technical Field

[0001] The invention belongs to the field of cable bridges, in particular to a cable bridge device. Background Art

[0002] Cable tray is a kind of equipment used for laying and managing cables, and is used in buildings, industrial facilities, data centers and other occasions; cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supports and installation accessories.

[0003] The cable tray can be installed independently in the building or laid on various buildings and pipe gallery supports. The cable tray must be dustproof, anti-corrosion, fire-retardant and meet relevant earthquake resistance requirements.

[0004] The cable tray has a relatively simple structure and is only capable of storing cables. However, the cable tray stores cables of many electrical equipment. As time goes by, when some of the electrical equipment is no longer in use, the corresponding cables lose their function, or the electrical equipment has a short circuit or other fault during use, causing the corresponding cables to burn out, and the cables need to be taken out. The taken out cables can not only be recycled and reused, but also only by taking out the old cables can there be space to lay new cables. However, the cables in the cable tray are often stacked. If the cable to be taken out is at the bottom, it is necessary to turn all the cables outwards to take out the corresponding cable. This is not only extremely cumbersome, but also requires disassembling all the cable trays through which the cables pass. In the process of turning over the cables, not only is there a danger, but it is also easy for other cables to entangle with each other, resulting in obstruction of the removal process.

[0005] To this end, the present invention provides a cable tray device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a cable bridge device described in the present invention includes a bridge frame, the top surface and both ends of the bridge frame are open, the top of the bridge frame is provided with an upper cover adapted to the bridge frame, a support frame for lifting the bridge frame is provided below the bridge frame, both ends of the support frame are fixedly connected with hanging columns, a plurality of superimposed tubes are provided inside the bridge frame, the superimposed tubes are provided in a bent shape, the superimposed tubes are fitted with the surface of the cable, and a driving bar for driving the superimposed tube to vibrate is provided on the inner side of the superimposed tube;

[0008] Preferably, through the provision of overlapping tubes, the support frame is fixed to the ceiling using hanging columns, the bridge frame is lifted by the support frame, and adjacent support frames are connected using connectors, so that the cables can be laid from the top; when laying the cables, it is necessary to first unfold the bent overlapping tubes and lay the cables on the surface of the overlapping tubes layer by layer, and it is necessary to ensure that the cables are in contact with the overlapping tubes. Depending on the volume of the bridge frame and the length of the overlapping tubes, the overlapping tubes can be bent once or multiple times; when a certain cable needs to be taken out, the overlapping tubes are driven to vibrate by the vibration of the driving bar, and the vibration effect of the overlapping tubes is similar to that of a vibrating rod. Since all the cables are in contact with the overlapping tubes, under high-frequency and small-amplitude vibrations, the friction between the cables will be intermittently reduced, because under the action of vibration, the cables will be intermittently in a state of not contacting other cables. At this time, it is only necessary to continuously push the ends of the cables outward The required cables can be taken out by pulling them out. After taking them out, the vibration will be stopped, and other cables will be basically unaffected. When starting to lay the cables, the top of the topmost stacking tube can be left vacant for laying newly added cables later. In this way, even if the cables below are pulled out, the outside of each cable can still be kept in contact with the stacking tube, so that the vibration extraction effect still exists; when more old cables are pulled out, the original stacking state will collapse, and the new cables will be laid on the top. The new cables can have a longer service life and will not need to be replaced. Even if they are damaged and need to be replaced, the upper cover can be directly opened to take out the upper cables directly; through this setting, when taking out the stacked cables, the cables below can be taken out quickly and effectively, which greatly improves the processing efficiency, and the impact of the surrounding on the cables is relatively low, the operation process is also safer, and the vibration effect is high-frequency and small-amplitude, which will not damage the original cables.

[0009] Preferably, the interior of the support frame is hollow, a plurality of storage bottles are arranged inside the support frame, a side drive seat is fixedly connected to one side of the support frame, a plurality of air pumps are installed on the surface of the side drive seat, a plurality of one-way valves are installed on the surface of the stacked tube, the one-way valves are connected with the storage bottles and the air pumps, a temperature measuring plate for measuring the temperature of the bridge frame is installed on one side of the side drive seat, and the temperature of the bridge frame is measured by attaching the temperature measuring plate to the bottom of the bridge frame. Since the interior of the bridge frame is full of cables, once a cable short-circuit generates high temperature, fire is likely to occur, and the outer skin of the cable is often made of flammable rubber material, which is likely to cause large-scale fires. Through the setting of the air pump and the storage bottle, the air pump works periodically, and inputs air flow to the one-way valve through the air pump, and the one-way valve sprays the air flow from the cable, which can not only effectively cool the cable and clean the surface, but also use the air flow as an auxiliary in the stage of pulling out the cable to help reduce the surface friction of the cable. In hot weather, the air pump can be opened more frequently; when the temperature measuring board measures that the temperature is too high, the carbon dioxide liquid stored in the storage bottle will be connected to the one-way valve, and the carbon dioxide will be released after the liquid vaporizes to isolate the air, so as to achieve the effect of fire extinguishing and cooling. Through this setting, the hidden danger of large-scale fire caused by accumulated cables is effectively reduced.

[0010] Preferably, the temperature measuring plate is fitted with the bottom surface of the bridge frame, and the temperature measuring plate is composed of a plurality of metal bifurcated plates, and the plurality of metal bifurcated plates are equidistantly distributed on the bottom surface of the bridge frame. The temperature measuring plate is fitted with the bridge frame, and the bridge frame is made of metal, and has a fast heat transfer effect, so that the surface temperature of the cables inside the bridge frame can be effectively detected, and the temperature measuring plate is located below the bridge frame. When there is a high temperature hazard indoors, the storage bottle can also be started to open, and carbon dioxide gas will be ejected from the gap of the bridge frame to assist in eliminating the high temperature hazard and reduce the time for the high temperature to spread to the cable.

[0011] Preferably, a plurality of driving motors are fixedly connected to the inner side of the side driving seat, and the output end of the driving motor is transmission-connected to the driving bar.

The plurality of eccentric blocks are equidistantly arranged, and the overlapping tube passes through the bridge frame and is connected to the side driving seat, and the driving motor drives the driving bar to rotate. Since the driving bar is made of a flexible material, even if the overlapping tube and the driving bar are bent many times, the driving bar can still transmit the rotational power to the end. At the same time, as the driving bar rotates, the eccentric block will be driven to rotate, and the center of gravity of the eccentric block is not in the center, so vibration will be generated during rotation, thereby causing the entire overlapping tube to vibrate at a high frequency, thereby realizing the function of loosening the cable.

[0012] Preferably, a plurality of binding strips for binding the middle part of the overlapping tube are fixedly connected inside the bridge frame, a through hole is opened from top to bottom at the end of the overlapping tube, a plurality of docking hooks matched with the through holes are fixedly connected inside the bridge frame, and a lock buckle matched with the docking hook is also rotatably connected to the inner side of the bridge frame. When the cable and the overlapping tube are fixed, the end of the overlapping tube is hung on the docking hook and the docking hook is passed through the through hole to fix the overlapping tube, and then the lock buckle is fixed to prevent the end of the overlapping tube from excessively shifting during vibration.

[0013] Preferably, a plurality of partition frames are fixedly connected to the inner bottom surface of the bridge frame, and the plurality of partition frames are arranged equidistantly. The stacking tube is located in the gap between adjacent partition frames, and the thickness of the stacking tube is greater than the thickness of the partition frame. The arrangement of the partition frame leaves some space at the bottom of the cable to improve the heat dissipation effect, and at the same time, the stacking tube is placed in the gap of the partition frame, so that the center of the cable will not bulge, and the thickness of the stacking tube is greater than the thickness of the partition frame, ensuring that the cable is pressed on the outside of the stacking tube.

[0014] Preferably, two transmission tubes are arranged on the inner side of the stacked tube, the transmission tubes are made of flexible material, connected to the air pump and the storage bottle, the transmission tubes are connected to a plurality of one-way valves, and the output ends of the air pump and the storage bottle are both equipped with one-way structures, the air pump and the storage bottle are connected to the one-way valves through the transmission tubes, the air pump is turned on intermittently to allow air to spray outward from the one-way valve, the opening valve of the storage bottle is connected to the temperature measuring structure of the temperature measuring plate, and is opened when the temperature is too high, and the one-way structure is set to prevent the storage bottle and the air pump from interfering with each other.

[0015] Preferably, an isolation tube is sleeved on the outer side of the driving bar, the inner diameter of the isolation tube is larger than the length of the eccentric block, and the two ends of the isolation tube are fixedly connected to the two ends of the overlapping tube. The setting of the isolation tube prevents the transmission tube from contacting the driving bar, thereby reducing mutual interference between structures. The distribution part of the transmission tube is connected to the overlapping tube for vibration transmission.

[0016] Preferably, a plurality of connecting holes are provided on both sides of the bridge frame, and the connecting holes are arranged in a vertical long strip shape. The opening positions of the plurality of connecting holes are staggered with the positions of the overlapping tubes. The overlapping tubes are connected to the side driving seats through a butt tube. The connecting holes are used to insert bolts for fixing the bridge frame and the connecting parts. The overlapping tubes can be removed from the butt tubes. A transmission shaft is connected to one end of the driving bar, and the transmission shaft is rotatably connected to the overlapping tubes. When the overlapping tubes and the butt tubes are installed, the driving motor drives the driving shaft and then drives the driving bar. With this arrangement, the overlapping tubes can be disassembled at will.

[0017] Preferably, the top of the bridge frame is arranged in an inward buckled shape, and the two ends of the upper cover are arranged in a bent shape. A plurality of fixing bolts for fixing the upper cover and the bridge frame are installed on the top surface of the upper cover. The upper cover can be slid from one side of the bridge frame and inserted into the top of the bridge frame, or can be pressed down from the top to engage on top of the bridge frame, and the upper cover and the bridge frame are fixed using the fixing bolts.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A cable tray device described in the present invention, through the setting of the overlapping tube, when it is necessary to take out a certain cable, the vibration of the overlapping tube is driven by the vibration of the driving bar to drive the vibration of the overlapping tube, and the vibration effect of the overlapping tube is similar to that of the vibrating rod. Since all the cables are in contact with the overlapping tube, under the high-frequency and small-amplitude vibration, the friction between the cables will be intermittently reduced, because under the action of the vibration, the cables will be intermittently in a state of not contacting other cables. At this time, it is only necessary to continuously pull out the end of the cable to take out the required cable. After taking it out, stop the vibration and other cables are basically unaffected.

[0020] 2. A cable tray device described in the present invention is attached to the bottom of the tray frame through a temperature measuring plate to measure the temperature of the tray frame. Since the interior of the tray frame is full of cables, once a cable short-circuit generates high temperature, fire is likely to occur, and the outer skin of the cable is often made of flammable rubber material, which is easy to cause a large-scale fire. Through the arrangement of an air pump and a storage bottle, the air pump works periodically, and air flow is input to the one-way valve through the air pump, and the one-way valve sprays the air flow from the cable, which can not only effectively cool the cable and clean the surface, but also use the air flow as an auxiliary in the stage of pulling out the cable to help reduce the surface friction of the cable.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 7 As shown, a cable bridge device according to an embodiment of the present invention comprises a bridge frame 1, the top surface and both ends of the bridge frame 1 are open, the top of the bridge frame 1 is provided with an upper cover 2 adapted to the bridge frame 1, a support frame 4 for lifting the bridge frame 1 is provided below the bridge frame 1, both ends of the support frame 4 are fixedly connected with hanging columns 5, a plurality of superimposed tubes 7 are provided inside the bridge frame 1, the superimposed tubes 7 are bent, the superimposed tubes 7 are fitted with the cable surface, and a driving bar 16 for driving the superimposed tube 7 to vibrate is provided on the inner side of the superimposed tube 7;

[0032] By setting up the overlapping tube 7, the support frame 4 is fixed to the ceiling using the hanging column 5, the bridge frame 1 is lifted by the support frame 4, and the adjacent support frames 4 are connected using connectors, so that the cable can be laid from the top; when laying the cable, it is necessary to unfold the bent overlapping tube 7 first, and lay the cable on the surface of the overlapping tube 7 layer by layer, and it is necessary to ensure that the cable is in contact with the overlapping tube 7. According to the volume of the bridge frame 1 and the length of the overlapping tube 7, the overlapping tube 7 can be bent once or multiple times; when a certain cable needs to be taken out, the driving bar 16 is used to vibrate the overlapping tube 7, and the vibration effect of the overlapping tube 7 is similar to that of a vibrating rod. Since all the cables are in contact with the overlapping tube 7, under high-frequency and small-amplitude vibrations, the friction between the cables will be intermittently reduced, because under the action of vibration, the cables will be intermittently in a state of not contacting other cables. At this time, the two ends of the discarded cable are first cut off, and then Only by continuously pulling out the end of the cable, the required cable can be taken out. After taking it out, stop vibrating, and other cables are basically not affected. When starting to lay the cable, the top of the topmost stacking tube 7 can be left vacant for laying the newly added cables at a later time. In this way, even if the lower cables are pulled out, the outer side of each cable can still be kept in contact with the stacking tube 7, so that the vibration extraction effect still exists; when more old cables are pulled out, the original stacking state will collapse, and the new cables will be laid on the top. The new cables can be used for a longer life and will not need to be replaced. Even if they are damaged and need to be replaced, the upper cover 2 can be directly opened to take out the upper cables directly; through this arrangement, when taking out the stacked cables, the lower cables can be taken out quickly and effectively, which greatly improves the processing efficiency, and the surrounding impact on the cables is relatively low, the operation process is also relatively safe, and the vibration effect is high-frequency and small-amplitude, which will not damage the original cables.

[0033] The interior of the support frame 4 is hollow, and a plurality of storage bottles 18 are arranged inside the support frame 4. A side drive seat 6 is fixedly connected to one side of the support frame 4, and a plurality of air pumps 12 are installed on the surface of the side drive seat 6. A plurality of one-way valves 20 are installed on the surface of the stacking tube 7, and the one-way valves 20 are connected to the storage bottles 18 and the air pumps 12. A temperature measuring plate 13 for measuring the temperature of the bridge frame 1 is installed on one side of the side drive seat 6;

[0034] During operation, the temperature of the bridge frame 1 is measured by attaching the temperature measuring plate 13 to the bottom of the bridge frame 1. Since the bridge frame 1 is full of cables, once a cable short-circuit generates high temperature, it is easy to catch fire, which is easy to cause a large-scale fire. Through the setting of the air pump 12 and the storage bottle 18, the air pump 12 works periodically, and the air flow is input to the one-way valve 20 through the air pump 12. The one-way valve 20 sprays the air flow from the cable, which can not only effectively cool the cable and clean the surface, but also use the air flow as an auxiliary in the stage of pulling out the cable to help reduce the surface friction of the cable. In hot weather, the air pump 12 can be opened more frequently; when the temperature measuring plate 13 measures that the temperature is too high, the carbon dioxide liquid stored in the storage bottle 18 will be connected to the one-way valve 20, and the carbon dioxide will be released after the liquid vaporizes to isolate the air, so as to achieve the effect of fire extinguishing and cooling. Through this setting, the hidden danger of large-scale fire caused by the accumulated cables is effectively reduced.

[0035] The temperature measuring plate 13 is fitted with the bottom surface of the bridge frame 1, and the temperature measuring plate 13 is composed of a plurality of metal bifurcated sheets, and the plurality of metal bifurcated sheets are equidistantly distributed on the bottom surface of the bridge frame 1;

[0036] During operation, the temperature measuring plate 13 fits closely to the bridge frame 1, which is made of metal and has a fast heat transfer effect, so that the surface temperature of the cables inside the bridge frame 1 can be effectively detected, and the temperature measuring plate 13 is located below the bridge frame 1. When there is a high temperature hazard indoors, the storage bottle 18 can also be started to open, and carbon dioxide gas will be ejected from the gap in the bridge frame 1, which helps eliminate the high temperature hazard and reduces the time for the high temperature to spread to the cables.

[0037] A plurality of drive motors are fixedly connected to the inner side of the side drive seat 6, and the output end of the drive motor is transmission-connected to the drive bar 16, and the drive bar 16 is made of flexible material. A plurality of eccentric blocks 17 are fixedly connected to the outer side of the drive bar 16, and the plurality of eccentric blocks 17 are arranged equidistantly. The stacked tube 7 passes through the bridge frame 1 and is connected to the side drive seat 6;

[0038] During operation, the driving motor drives the driving bar 16 to rotate. Since the driving bar 16 is made of flexible material, even if the overlapping tube 7 and the driving bar 16 are bent many times, the driving bar 16 can still transmit the rotational power to the end. At the same time, as the driving bar 16 rotates, the eccentric block 17 is driven to rotate. The center of gravity of the eccentric block 17 is not in the center, and vibration will be generated during the rotation, so that the entire overlapping tube 7 vibrates at a high frequency, thereby realizing the function of loosening the cable.

[0039] A plurality of restraining strips 10 for restraining the middle of the stacked tube 7 are fixedly connected inside the bridge frame 1, and a through hole is opened from top to bottom at the end of the stacked tube 7. A plurality of docking hooks 11 adapted to the through holes are fixedly connected inside the bridge frame 1, and a lock buckle adapted to the docking hook 11 is also rotatably connected to the inner side of the bridge frame 1;

[0040] During operation, after the cable and the stacking tube 7 are fixed, the end of the stacking tube 7 is hung on the docking hook 11, and the docking hook 11 is passed through the through hole to fix the stacking tube 7. The lock is located above the docking hook 11. After the stacking tube 7 passes through the docking hook 11, the lock is used to block the end of the docking hook 11 to prevent the stacking tube 7 from slipping out of the docking hook 11 and to prevent the end of the stacking tube 7 from excessively shifting during vibration.

[0041] A plurality of partition frames 8 are fixedly connected to the inner bottom surface of the bridge frame 1, and the plurality of partition frames 8 are arranged at equal distances. The stacked tube 7 is located in the gap between adjacent partition frames 8, and the thickness of the stacked tube 7 is greater than the thickness of the partition frames 8;

[0042] During operation, the partition frame 8 is set to leave some space at the bottom of the cable to improve the heat dissipation effect. At the same time, the stacking tube 7 is placed in the gap of the partition frame 8, so that the center of the cable will not bulge. The thickness of the stacking tube 7 is greater than the thickness of the partition frame 8, ensuring that the cable is pressed on the outside of the stacking tube 7.

[0043] Two transmission tubes 15 are arranged inside the stacked tube 7. The transmission tubes 15 are made of flexible material. The transmission tubes 15 are connected to the air pump 12 and the storage bottle 18. The transmission tubes 15 are connected to a plurality of one-way valves 20, and the output ends of the air pump 12 and the storage bottle 18 are both equipped with one-way structures.

[0044] During operation, the air pump 12 and the storage bottle 18 are connected to the one-way valve 20 through the transmission pipe 15. The air pump 12 is opened intermittently to allow the air flow to be ejected outward from the one-way valve 20. The opening valve of the storage bottle 18 is connected to the temperature measuring structure of the temperature measuring plate 13 and is opened when the temperature is too high. The one-way structure is set so that the storage bottle 18 and the air pump 12 do not interfere with each other. The specific connection method and transmission method are as follows: the transmission pipe 15 is connected to all the one-way valves 20, and the rear part of the transmission pipe 15 extends to the inside of the side drive seat 6, and is connected to the air pump 12 and The storage bottle 18 is connected, and the one-way structure can be an air valve, which only allows the air pump 12 and the storage bottle 18 to output gas outward in one direction. When the air pump 12 is turned on, the air is directly transferred to the one-way valve 20 through the transmission tube 15 to allow the air flow to spray outward, and the air valve of the storage bottle 18 prevents the air flow of the air pump 12 from entering the interior of the storage bottle 18; when the storage bottle 18 is turned on, the gas in the storage bottle 18 can also be transferred to the one-way valve 20 through the transmission tube 15. Since there is an air valve at the output end of the air pump 12, the gas will not affect the air pump 12.

[0045] The outer side of the driving bar 16 is sleeved with an isolation tube 14, the inner diameter of the isolation tube 14 is greater than the length of the eccentric block 17, and the two ends of the isolation tube 14 are fixedly connected to the two ends of the superimposed tube 7;

[0046] During operation, the isolation tube 14 is arranged so that the transmission tube 15 does not contact the driving bar 16, thereby reducing mutual interference between structures. The distribution part of the transmission tube 15 is connected to the overlapping tube 7 for transmitting vibration.

[0047] A plurality of connection holes 9 are provided on both sides of the bridge frame 1. The connection holes 9 are arranged in a vertical strip shape. The opening positions of the plurality of connection holes 9 are staggered with the positions of the stacking tubes 7. The stacking tubes 7 are connected to the side drive seat 6 via a butt joint 19.

[0048] During operation, the connecting hole 9 is used to insert bolts for fixing the bridge frame 1 and the connecting parts. The overlapping tube 7 can be removed from the butt tube 19. One end of the driving bar 16 is connected to a transmission shaft, and the transmission shaft is rotatably connected to the overlapping tube 7. When the overlapping tube 7 and the butt tube 19 are installed, the driving motor drives the driving bar 16 by driving the transmission shaft. With this arrangement, the overlapping tube 7 can be removed at will.

[0049] The top of the bridge frame 1 is inwardly buckled, the two ends of the upper cover 2 are bent, and a plurality of fixing bolts 3 for fixing the upper cover 2 and the bridge frame 1 are installed on the top surface of the upper cover 2;

[0050] During operation, the upper cover 2 can be slid from one side of the bridge frame 1 and inserted into the top of the bridge frame 1 , or can be pressed down from the top and then engaged on the top of the bridge frame 1 , and the upper cover 2 and the bridge frame 1 are fixed using the fixing bolts 3 .

[0051] During operation, the support frame 4 is fixed to the ceiling by setting the overlapping tube 7, and the bridge frame 1 is lifted by the support frame 4. The adjacent support frames 4 are connected by connecting pieces, so that the cables can be laid from the top. When laying the cables, the bent overlapping tube 7 needs to be unfolded first, and the cables are laid layer by layer on the surface of the overlapping tube 7. It is necessary to ensure that the cables are in contact with the overlapping tube 7. According to the volume of the bridge frame 1 and the length of the overlapping tube 7, the overlapping tube 7 can be bent once or multiple times. When a certain cable needs to be taken out, the driving bar 16 is used to vibrate the overlapping tube 7. The vibration effect of the overlapping tube 7 is similar to that of a vibrating rod. Since all the cables are in contact with the overlapping tube 7, under high-frequency and small-amplitude vibrations, the friction between the cables will be intermittently reduced, because under the action of vibration, the cables will be intermittently in a state of not contacting other cables. At this time, it is only necessary to The end of the cable is continuously pulled outward, and the required cable can be taken out. After taking it out, the vibration is stopped, and other cables are basically not affected. When the cable is laid, the top of the topmost stacking tube 7 can be left vacant for laying the newly added cables at a later time. In this way, even if the lower cables are pulled out, the outer side of each cable can still be kept in contact with the stacking tube 7, so that the vibration extraction effect still exists; when more old cables are pulled out, the original stacking state will collapse, and the new cables will be laid on the top. The new cables can be used for a longer life and will not be replaced. Even if they are damaged and need to be replaced, the upper cover 2 can be directly opened to take out the upper cables directly; through this arrangement, when taking out the stacked cables, the lower cables can be taken out quickly and effectively, which greatly improves the processing efficiency, and the surrounding impact on the cables is relatively low, the operation process is also safer, and the vibration effect is high-frequency and small-amplitude, which will not damage the original cables;

[0052] The temperature measuring plate 13 is attached to the bottom of the bridge frame 1 to measure the temperature of the bridge frame 1. Since the bridge frame 1 is full of cables, once a cable short-circuit generates high temperature, it is easy to catch fire, and the outer skin of the cable is often made of flammable rubber material, which is easy to cause a large-scale fire.

In hot weather, the air pump 12 can be opened more frequently; when the temperature measuring plate 13 measures that the temperature is too high, the carbon dioxide liquid stored in the storage bottle 18 will be connected to the one-way valve 20, and the carbon dioxide will be released after the liquid vaporizes to isolate the air, so as to achieve the effect of fire extinguishing and cooling. Through this setting, the hidden danger of large-scale fire caused by the accumulated cables is effectively reduced;

[0053] The temperature measuring plate 13 is attached to the bridge frame 1. The bridge frame 1 is made of metal and has a fast heat transfer effect, so that the surface temperature of the cables inside the bridge frame 1 can be effectively detected. The temperature measuring plate 13 is located below the bridge frame 1. When there is a high temperature hazard indoors, the storage bottle 18 can also be started to open, and carbon dioxide gas will be ejected from the gap of the bridge frame 1 to help eliminate the high temperature hazard and reduce the time for the high temperature to spread to the cables.

[0054] The driving motor drives the driving bar 16 to rotate. Since the driving bar 16 is made of flexible material, even if the stacking tube 7 and the driving bar 16 are bent for many times, the driving bar 16 can still transmit the rotational power to the end. At the same time, as the driving bar 16 rotates, the eccentric block 17 is driven to rotate. The center of gravity of the eccentric block 17 is not at the center, and vibration will be generated during the rotation process, so that the entire stacking tube 7 vibrates at a high frequency, thereby realizing the function of loosening the cable;

[0055] After the cable and the stacking tube 7 are fixed, the end of the stacking tube 7 is hung on the docking hook 11, and the docking hook 11 is passed through the through hole to fix the stacking tube 7, and then the lock is fixed to prevent the end of the stacking tube 7 from excessive displacement during vibration;

[0056] The partition frame 8 is set to leave some space at the bottom of the cable to improve the heat dissipation effect. At the same time, the stacking tube 7 is placed in the gap of the partition frame 8, so that the center of the cable will not bulge. The thickness of the stacking tube 7 is greater than the thickness of the partition frame 8, ensuring that the cable is pressed on the outside of the stacking tube 7;

[0057] The air pump 12 and the storage bottle 18 are both connected to the one-way valve 20 through the transmission pipe 15. The air pump 12 is opened intermittently to allow the air flow to be ejected outward from the one-way valve 20. The opening valve of the storage bottle 18 is connected to the temperature measuring structure of the temperature measuring plate 13 and is opened when the temperature is too high. The one-way structure is set so that the storage bottle 18 and the air pump 12 do not interfere with each other.

[0058] The setting of the isolation tube 14 prevents the transmission tube 15 from contacting the driving bar 16, reducing the mutual interference between the structures. The distribution part of the transmission tube 15 is connected to the stacking tube 7 for the transmission of vibration;

[0059] The connection hole 9 is used to insert bolts for fixing the bridge frame 1 and the connecting piece. The stacked tube 7 can be removed from the butt tube 19. One end of the drive bar 16 is connected to a transmission shaft, and the transmission shaft is rotatably connected to the stacked tube 7. When the stacked tube 7 and the butt tube 19 are installed, the drive motor drives the drive shaft and then drives the drive bar 16. With this arrangement, the stacked tube 7 can be disassembled at will.

[0060] The upper cover 2 can be slid from one side of the bridge frame 1 and inserted into the top of the bridge frame 1 , or can be pressed down from the top to engage on the top of the bridge frame 1 , and the upper cover 2 and the bridge frame 1 are fixed using the fixing bolts 3 .

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
