Detailed Description
As shown in figure 1, the composite cable bridge comprises a base 1 fixedly installed on a building body, more than one elastic connecting piece 2 is arranged on the base 1 side by side, a fixing plate 8 is arranged at one end of each elastic connecting piece 2, an assembly cavity is arranged on each fixing plate 8, a bridge box 5 is arranged in the assembly cavity of each fixing plate 8, at least one cable 6 is arranged in each bridge box 5, the cable 6 penetrates through the arrangement cavity in the bridge box 5 and extends out of the arrangement cavity, an elastic air bag 3 is arranged between each elastic connecting piece 2 and the base 1, the elastic air bag 3 props up the elastic connecting pieces 2, and the top opening face of the bridge box 5 is far away from the building body, when 3 inside gasless times of elasticity gasbag, the opening face at 5 tops of crane span structure box and the contact of building body are sealed, and every cable is just to an elasticity gasbag 3, connects through an air duct 4 between elasticity gasbag 3 and the cable 6 and switches on.
In this embodiment, the elastic connection piece 2 is made of a high-elasticity memory metal piece, one end of the elastic connection piece is welded with the base 1, the other end of the elastic connection piece is welded with the fixing plate 8, and the fixing plate 8 is fixedly connected with the bridge box 5 through screws.
One side of the top opening end of the cavity which is relatively arranged on the building body is bonded with a silica gel sealing layer 7, when the top of the bridge box 5 is contacted with the silica gel sealing layer 7, the top opening surface of the bridge box 5 is sealed through the silica gel sealing layer 7, when one cable 6 goes wrong, the gas in the corresponding elastic airbag 3 is discharged, the supporting force of the elastic airbag 3 is lost, at the moment, under the action of the elastic connecting sheet 2, the top of the corresponding bridge box 5 is contacted with the lower end surface of the silica gel sealing layer 7, so that the protection of the internal circuit of the bridge box 5 is realized, as shown in figure 2, if the cable is damaged due to spontaneous combustion, the oxygen can be burnt out through a sealed space to automatically extinguish the fire, the isolation between the cable and other cables is realized, and the transmission of flames is prevented;
because the problem cable resumes deformation and silica gel sealing layer sealing contact, so the staff can the very first time discover the problem cable, reduce maintenance time, promote the precision when overhauing, promote work efficiency greatly.
If all cables 6 are problematic, all cables will recover their deformation, which is in contact with the silicone sealant, as shown in fig. 3, to hermetically protect all cables 6. The invention has good buffer capacity and heat dissipation effect because the cable is in an elastic swing state when in use, realizes the contact between the cable and air by utilizing the swing of air flow, increases the contact area and reduces the accumulation of heat.
Wherein, as shown in fig. 4, every cable 6 inside all is provided with a sealed cable chamber (not shown), 4 sections of air ducts communicate with each other with the inside gas storage chamber of elasticity gasbag 3, the other end passes bridge box 5 and switches on with the inside cable chamber butt joint of cable, because cable 6 switches on with elasticity gasbag 3, consequently when the cable goes wrong, for example the epidermis damage that ageing caused, the damage that artificial construction caused or the epidermis damage that spontaneous combustion caused, all can lead to the inside gaseous effluvium of elasticity gasbag, so in case the elasticity that loses the elasticity gasbag struts, the corresponding bridge box will resume deformation, realize quick isolation and seal. And when normal use, can realize the heat exchange between elasticity gasbag and the cable, in the inside hot-air of cable can be transmitted to elasticity gasbag promptly, inside cold air enters into the cable, reaches better heat dissipation.
Wherein, be provided with the cable hole on the crane span structure box 5, cable 6 passes the cable hole and beats between the glue water-tight fixed with the cable hole, guarantees the leakproofness.
The elastic air bag 3 is made of elastic rubber materials, more than one heat dissipation guide rod 31 is embedded in the elastic air bag, part of the heat dissipation guide rod 31 extends into the air storage cavity, and part of the heat dissipation guide rod extends out of the air storage cavity and contacts with air. After the hot air in the cable enters the elastic airbag 3, the heat of the air in the elastic airbag 3 can be quickly reduced by radiating through a large number of radiating guide rods 31, so that the air exchange with the cable 6 is realized.
Wherein, elasticity gasbag 3 is located the upper end position face of cable, and hot-air enters into elasticity gasbag 3 in, and inside cold air enters into the cable, the cable passes through the air duct and exchanges gas with elasticity gasbag, according to the cold air of hot-air come-up principle that sinks, guarantees that the inside air of cable is cold air.
The invention has the beneficial effects that: the cable is arranged in a suspension manner, has very good buffering capacity and is suitable for being applied to vibration occasions;
in the cable bridge, the elastic air bag is communicated with the cable, so that the heat in the cable can be transmitted into the elastic air bag for heat dissipation, and the heat dissipation capacity of the cable is improved;
when the cable has a problem, the gas in the elastic air bag is discharged, and at the moment, the corresponding bridge box loses the propping force, the bridge box is quickly reset under the action of the elastic connecting sheet, so that the top opening end of the bridge box is sealed, and the cable with the problem is sealed, protected and isolated, therefore, the cable can be responded in time no matter what reason causes the cable problem;
and fourthly, when the cable has a problem, the corresponding bridge box can be reset, so that a worker can know whether the cable has the problem at a glance and quickly confirm the cable with the problem during maintenance, the time consumed by routing inspection is reduced, and the accuracy of identifying the cable with the problem is increased.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention.
