Description
Technical field
The present invention relates to the leaky cable fixing device in the general speed of urban track traffic and high-speed railway wireless communication system
Technical field, more particularly to a kind of leakage coaxial cable fire prevention suspender with auto-lock function.
Background technology
Leakage coaxial cable fixes the form for using suspender, fills a set of common suspender every 1 ~ 1.3 meter ampere, often installs nine
Common suspender is covered, a set of fire prevention suspender need to be installed, the effect of fire prevention suspender is in the event of a fire, it is ensured that leakage coaxial
Cable does not come off from wall；The typical structure of existing leakage coaxial cable fire prevention suspender has two kinds of shapes of wire-type and plate-like type
Formula；As shown in figure 1, linear structure form metal fireproof ring is made up of U-shaped ring 14, metal connecting plate 15 and fixing nut 16, material
Mostly carbon steel, preservative treatment is carried out by zincincation processing, is used for a long time under environment moist in tunnel, screw thread and spiral shell
Corrosion phenomena occurs in mother, during later maintenance, and fixing nut 16 can not be removed from U-shaped ring 14, only by U-shaped ring 14
It is sawed-off, leakage coaxial cable could be removed to maintenance, be inconvenient, it is careless slightly during sawed-off becket to cut
Cable causes damage；And, it is necessary to be respectively mounted plain washer, spring pad at the two ends of U-shaped ring 14 when being fixed using such a mode
Circle and hex nut, leakage coaxial cable setting height(from bottom) in tunnel is more than 4.2 meters, and work high above the ground is inconvenient, and is often gone out
The phenomenon that existing plain washer, spring washer and hex nut drop, because tunnel intraoral illumination condition is very severe, the nut fallen down is very
Difficulty is found, using this mounting means, and inconvenience of on the one hand constructing, efficiency of construction is relatively low；On the other hand, due in installation process
Dropping for fastener, causes very big waste；Another further aspect, piston effect when being run due to train in tunnel is installed
Fastener in the presence of chronic fatigue oscillating load, it is easy to occur loosen phenomenon so that cause leakage coaxial cable take off
Fall, potential safety hazard is caused to train operation；Prior one side is, if the fastener cleaning dropped during installation is not clean,
When train high speed is by tunnel, the fastener such as any one plain washer that comes off, spring washer and nut is as one under aerodynamic effect
Flight bullet, jeopardize traffic safety；As shown in Fig. 2 platy structure form metal fireproof ring includes ring 17, metal on metal
Lower ring 19 and fixing bolt 18 are constituted, and ring 19 is compressing by 304 stainless steel plates under ring 17 and metal on metal, and width is about
25mm or so, the deficiency of linear structure form metal fireproof ring is still had using such a mode.
