Abstract
The utility model relates to a clamp for a leaky cable. The clamp comprises a corbel G-shaped seat formed by integrated construction of a base plate and an inclined block; a recessed part used for accommodating a leaky cable is formed in the corbel G-shaped seat; a cover body and the corbel G-shaped seat can be fixedly connected by respective wedge-shaped fixture block mechanisms thereof; a leaky cable compacting sheet is formed on the cover and is arranged to be opposite to the bottom surface of the corbel G-shaped seat in the installation state of the clamp, and the leaky cable compacting sheet butts against and tightly presses the leaky cable in the corbel G-shaped seat while the leaky cable compacting sheet and the corbel G-shaped seat are locked through respective wedge-shaped fixture block mechanisms thereof. With such a technical scheme, a product structure maximally guarantees that the problem of orientation in installation of leaky cables in a railway tunnel is overcome; if the leaky cable is to be mounted at a height of about 2.5 m, a desired orientation angle can be obtained only by aligning a protruding channel at the bottom of the leaky cable with a recessing channel at the lower side of a system to naturally form a horizontal direction; and for other heights, corresponding radiation angles can be adjusted according to different positions of a locating slot, and thus, the problem of orientation is overcome.
Description
Technical field
The utility model relates to a kind of cable sectional fixture, but particularly relates to a kind of leakage cable clip tool of leaky coaxial cable setoff installation.
Background technology
In area, Chinese Railway mountain area, city underground and vcehicular tunnel in the covering of wireless communication signals, wireless signal covers the general mode that adopts leaky coaxial cable to add trunking in the tunnel space, the antenna height of railway private radio communication leaky coaxial cable is generally at 4.5 meters ~ 4.8 meters, carry out along the railway the public network wireless communication system leaky coaxial cable antenna height of signal covering generally at 2.2 meters ~ 3.0 meters, generally at 1.6 meters ~ 2.2 meters, leaky coaxial cable sets up and all adopts the anchor clamps mode to install in the subway.
After anchor clamps of the prior art are originally installed in the tunnel, the wireless signal radiation direction of leaky coaxial cable, namely only towards the axial direction of bolt, perpendicular to tunnel wall, after leaky coaxial cable is hung outside the tunnel, the wireless signal radiation direction is towards ground, and anchor clamps natural direction and bolt shaft are to consistent, when several leaky coaxial cables horizontally arrange, the certain interference of signal phase mutual of different leaky coaxial cables, regulation according to relevant is greater than 0.4 meter between two adjacent leaky coaxial cables, and so a part of leaky coaxial cable can only be arranged on the position that affects covering effect of signals.
Simultaneously, in the prior art, leaky coaxial cable anchor clamps middle part arranges set bolt, expansion bolt was fixed in mostly described bolt was to adopt, cover has the movable apertured becket of energy near bolt head, increase the distance of leaving tunnel wall, to improve covering effect of signals, but this connected mode, 1, can only not be fixed under leaky coaxial cable is also packed into, the staff can only be when work high above the ground like this, first fixing leaky coaxial cable anchor clamps, then leaky coaxial cable is installed in the leaky coaxial cable anchor clamps, and after can not below leaky coaxial cable being clamped the leaky coaxial cable anchor clamps, carry out operation ascending a height, work is inconvenient, when the leaky coaxial cable anchor clamps of installing, also will be first consistent to the position guarantee level of ruling; 2, the apertured becket loaded onto of cover, when mounted easily from falling down in the air, and fastness is poor after fixing, is prone to loosening phenomenon.
