Description
Technical Field
The invention relates to the technical field of cable bridges, in particular to a cable bridge with convenient connection and fireproof functions.
Background
The cable bridge is a rigid structure system composed of a groove type, tray type or step type straight line section, a bend-through, a tee joint, a four-way component, a supporting arm (arm type bracket), a hanger and the like, and the rigid structure system is closely connected with and supports the cable, so that the cable bridge can be fixed.
When the cable bridge is used, a plurality of bridge units need to be connected in sequence, and the existing connection mode is |: the end parts of the two bridge units 100 are provided with connecting plates 117, and the two ends of each connecting plate 117 are fixedly connected with the two bridge units 100 through screws 118, so that the connecting strength of the cable bridge is improved, and the connecting mode has three defects: firstly, the cable bridge is inconvenient to install and disassemble; secondly, the connection plate and the screw exposed outside influence the integral aesthetic property; thirdly, the cable in a single bridge unit is inconvenient to overhaul and lay at the later stage.
The reasons for the cable conductor to catch fire are two, and the contact often makes the circuit short circuit or the cable conductor generates heat and arouses the condition of a fire between the mixed and disorderly cable conductor in the cable testing bridge on the one hand, and the cable conductor is aroused to outside condition of a fire on the other hand. In order to solve the problem that the fire condition of the cable is difficult to find and the fire is difficult to extinguish, the cable bridge with the fire extinguishing function is released in the market, and the fire condition of the cable bridge is extinguished by arranging a fluid fire extinguishing agent on the inner side or the outer side of the cable bridge so as to reduce the loss of fire. But in the actual production, the actual fire extinguishing effect of the existing cable bridge with the fire extinguishing function is not ideal, and the reason is as follows: the fire flees to both ends along the cable testing bridge inner chamber, encourages the fire easily, and after the fire spread, a small amount of fire extinguishing agent plays some effects in the cable testing bridge, consequently wants to obtain good fire control effect, what to solve most is how to prevent the flow of fire to flee, and current cable testing bridge does not all have above-mentioned function.
