Description

Technical Field

[0001] The present disclosure relates to the technical field of cable laying equipment, and in particular to a bridge. Background Art

[0002] When cables are laid overhead, they are usually placed in a bridge for laying. For example, in the cover glass production line, more than a dozen pairs of edge drawing machines are needed on both sides of the tin bath section to stretch the glass liquid. The bridge for laying power cables for the edge drawing machines needs to span the tin bath with a width of 5-6 meters. However, since the temperature at the top of the tin bath is about 70°C, if ordinary cables are used, the cables are prone to aging and pose safety hazards in a high temperature environment for a long time; if high-temperature resistant cables are used, the power cables and control cables of all edge drawing machines require tens of thousands of meters of cables in total, which is too expensive compared to ordinary cables. For this reason, when the bridge is in a high-temperature environment, the bridge needs to be cooled to ensure the safety of the cables and prevent them from aging.

[0003] The prior art proposes a liquid-cooled cable bridge (CN 110364971 A), comprising: a bridge body, a cooling cavity filled with cooling liquid on the outside of the bridge body, and the cooling cavity is connected to a cooling pipe with flowing cooling liquid inside through a pipeline. The cooling cavity is filled with cooling liquid, and the cooling cavity is wrapped around the periphery of the bridge body. The cooling liquid in the cooling pipe can flow into the cooling cavity, and the cooling liquid in the cooling cavity can flow into the cooling pipe. When the bridge body is heated, the heat is transferred to the cooling liquid in the cooling cavity, and the cooling liquid carrying heat will flow into the cooling pipe. Since the cooling liquid in the cooling pipe is flowing, this part of the cooling liquid carrying heat will flow with the flowing cooling liquid in the cooling pipe to dissipate heat. The new cooling liquid will enter the cooling cavity from the cooling pipe for re-cooling, forming a circulating flow, thereby realizing heat exchange between the liquid in the cooling cavity and the cooling pipe, thereby achieving the purpose of cooling the bridge body.

[0004] Although the above-mentioned prior art can realize cooling of the bridge, since a cooling cavity needs to be set outside the bridge, the bridge needs to be suspended at a certain height, which will inevitably bring certain difficulties when installing the cooling cavity. At the same time, the external cooling cavity and cooling liquid have a certain weight. Therefore, it is necessary to increase the thickness of the bridge material or increase the cross-sectional size of the bridge to bear the load of the cooling cavity and cooling liquid, which will inevitably increase the manufacturing cost of the bridge. Based on this, how to realize cooling of the bridge by using the bridge's own structure without increasing the thickness of the bridge material and the cross-sectional size of the bridge is a problem that technicians in this field need to consider.

[0028] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be regarded as part of the specification. As mentioned in the above background technology, in order to prevent the aging of the cables and ensure the safety of the cables in a high temperature environment, the bridge needs to be cooled. Although the cooling of the bridge can be achieved through the existing technology, due to the need to set a cooling cavity outside the bridge, the bridge needs to be suspended at a certain height, which is bound to bring certain difficulties when installing the cooling cavity. At the same time, the external cooling cavity and cooling liquid have a certain weight. Therefore, it is necessary to increase the thickness of the bridge material or increase the cross-sectional size of the bridge to bear the load of the cooling cavity and the cooling liquid, which is bound to increase the manufacturing cost of the bridge. For this reason, how to achieve cooling of the bridge using the bridge's own structure without increasing the thickness of the bridge material and the cross-sectional size of the bridge is a problem that technicians in the field need to consider. Based on this, the inventor of the present application provides a bridge in one or more embodiments, wherein the cavity is divided into an upper cavity and a lower cavity by a partition, the upper cavity is used to place the cable, the cooling gas is discharged into the lower cavity through the air inlet, and the cooling gas is discharged into the upper cavity through multiple air holes to cool the cable, thereby avoiding the installation difficulty brought by the prior art and the need to increase the strength of the bridge material and increase the cross-sectional size of the bridge, which leads to an increase in the bridge manufacturing cost. It is believed that it can solve one or more problems in the prior art.

[0029] In view of the above-mentioned technical problems, the utility model provides a bridge frame, such as Figure 1 and Figure 2 As shown, it includes: a cavity 1, a partition 2, the partition 2 is arranged in the cavity 1 to separate the cavity 1 into an upper cavity 3 and a lower cavity 4, the upper cavity 3 is used to place the cable and has an opening on the top, and a plurality of air holes 5 are provided on the partition 2; an air inlet 6, the air inlet 6 is opened on the lower cavity 4 to discharge cooling gas into the lower cavity 4, and then discharge the cooling gas into the upper cavity 3 through the plurality of air holes 5 to cool the cable.

[0030] Specifically, the partition 2 divides the cavity 1 into an upper cavity 3 and a lower cavity 4. The upper cavity 3 is used to place cables, realizing the function of laying cables on the bridge. The cooling gas is discharged into the lower cavity 4 through the air inlet 6, and the cooling gas is then discharged into the upper cavity 3 through multiple air holes 5 to achieve cooling of the cables placed in the upper cavity 3. Furthermore, the cavity 1 can be made of high-temperature resistant materials, such as steel plates, and its outer wall can be coated with fire retardant paint to improve the fire resistance of the bridge and ensure the safety of the bridge in a high-temperature environment; the partition 2 can also be a steel plate, and the partition 2 must have a certain thickness to ensure that it can bear the weight of the cables thereon. The partition 2 can be connected to the inner wall of the cavity by welding, or installation grooves can be opened on two inner walls opposite to each other in the length direction of the cavity 1. The two ends of the partition 2 can be set in the installation grooves. The installation grooves can reduce the amount of welding and increase the installation speed on site.

[0031] Specifically, the bridge can be transported to the site for installation after being processed in the factory. The processing process is as follows: first, the cavity is processed. The side walls of the cavity 1 and the side walls and the bottom wall can be fully welded or spot welded. It can also be made by bending the steel plate. After the cavity 1 is completed, the partition 2 is welded in the cavity 1; when the installation groove is used, the partition 2 is installed in the installation groove after the cavity 1 is installed on site. In addition, according to the actual needs of the site, multiple cavities 1 can be connected together on site to form a bridge. During processing, bolt holes can be opened at the end of the side wall of the upper cavity 3. The bolt holes facilitate the connection between the cavities 1 on site.

[0033] In some embodiments, Figure 1 As shown, the air inlet 6 includes a plurality of air inlets 6, and the plurality of air inlets 6 are distributed along the length direction of the cavity 1. Specifically, the plurality of air inlets 6 can be opened on the side wall of the lower cavity 4 at equal intervals, and each section of the cable in the bridge can be cooled evenly through the plurality of air inlets 6, thereby ensuring the cooling effect on the entire cable.

[0034] In some embodiments, an air supply mechanism (not shown in the figure) is further included, and the air supply mechanism is connected to the air inlet 6 to provide cooling gas to the air inlet 6. The air supply mechanism is used to prepare cooling gas and send the cooling gas into the lower cavity 4 to cool the cables in the bridge.

Specifically, the temperature meter in the air supply mechanism collects the temperature of the cooling gas in real time and transmits the temperature value to the control device. The control device sends an instruction to the temperature regulating mechanism based on the received temperature value. The temperature regulating mechanism adjusts the output power based on the instruction, thereby realizing the adjustment of the temperature of the cooling gas in the air supply mechanism.

[0036] In some embodiments, a sensor (not shown) is provided in the upper cavity 3 to monitor the temperature in the upper cavity 3.

Specifically, the sensor transmits the monitored temperature value to the control device, and the control device sends an instruction to the valve based on the received temperature value, and the valve adjusts its opening based on the instruction, thereby controlling the flow rate of the cooling gas discharged into the lower cavity 4. The coordination of the valve, the control device and the sensor can ensure that the cable can be effectively cooled, and the problem of energy waste caused by excessive cooling can also be avoided. At the same time, automatic control of the cooling process is also realized.

Specifically, the bottom of the support block 7 is connected to the bottom wall in the lower cavity 4, and the top of the support block 7 is connected to the bottom surface of the partition 2 for supporting the partition 2. Further, multiple support blocks 7 may be provided and the multiple support blocks 7 may be evenly arranged in the lower cavity 4 to ensure the balanced stability of the support structure system of the partition 2. The support blocks 7 can avoid the load of the cables and the deformation of the partition 2 when laying the cables.

[0040] In some embodiments, a detachable cover plate 8 is provided on the opening. Specifically, the cover plate 8 can also be made of a steel plate. After the cavity is installed on site and the cables in the upper cavity 3 are laid, the cover plate 8 is installed on the opening to block the opening, thereby preventing dust and debris in the environment from entering the upper cavity 3; when the cable needs to be inspected, maintained, or replaced, the cover plate 8 is removed to open the opening. Specifically, a card slot can be provided on the side wall of the upper cavity 3, and a card strip can be provided on the cover plate 8, and the cover plate 8 can be installed on the opening by cooperating with the card strip and the card slot.

[0041] In some embodiments, a sealing groove 9 is provided on the cover plate 8 for sealing the cavity 1 into a closed space, and an exhaust port (not shown in the figure) is provided on the side wall of the upper cavity 3 for discharging the cooling gas in the upper cavity 3. Specifically, the sealing groove 9 can be made of rubber material, and the top of the side wall of the cavity 1 extends into the sealing groove 9 to achieve sealing of the cavity. The cooling gas is discharged into the closed cavity 1 through the air inlet 6, which can further increase the cooling efficiency. The cooling gas that has completed cooling in the cavity 1 can be discharged from the upper cavity 3 through the exhaust port. Furthermore, the exhaust port and the air supply mechanism can be connected through an exhaust pipe, and the cooling gas can be recycled after being cooled in the air supply mechanism, thereby achieving energy saving and emission reduction.
