Leaky coaxial cable clamp mechanism and leaky coaxial cable bearing system

Abstract

The invention discloses a leaky coaxial cable clamp mechanism and a leaky coaxial cable bearing system.The leaky coaxial cable clamp mechanism comprises a bearing support, a main clamp and at least two auxiliary clamps, the bearing support is fixed to an installation wall body, the main clamp and the at least two auxiliary clamps are all fixed to the bearing support, the at least two auxiliary clamps are arranged on the two sides of the main clamp at intervals, and the main clamp and the at least two auxiliary clamps are fixed to the bearing support. The auxiliary clamp can generate elastic deformation in the vibration state of the leaky coaxial cable so as to have a damping and buffering effect, and the main clamp is fixed relative to the bearing support in the vibration state of the leaky coaxial cable. According to the leaky coaxial cable clamp, the bearing requirement of the leaky coaxial cable can be met, the installation number of the leaky coaxial cable clamp mechanisms is effectively reduced, the situation that the bearing support is loosened due to the fact that the stress between the bearing support and the installation wall body is influenced by vibration can be avoided, the influence of the vibration on the stress between the main clamp and the leaky coaxial cable can be relieved or eliminated, larger clamping force can be applied to the leaky coaxial cable, and the leaky coaxial cable is prevented from being damaged. Therefore, the leaky coaxial cable is prevented from loosening, the safety performance is effectively improved, and axial displacement of the leaky coaxial cable under the action force of the tunnel wind tunnel effect is reduced or eliminated.

Description

technical field [0001] The invention relates to the technical field of leaky cable installation, in particular to a leaky cable clamp mechanism and a leaky cable bearing system. Background technique [0002] Leaky cable is the abbreviation of leaky coaxial cable, usually referred to as leaky cable or leaky cable. At present, leaky cables are generally used in railway tunnels, subway tunnels, highway tunnels, mines, parking lots, elevators and other places, mainly for the transmission and coverage of wireless communication signals. When the existing leaky coaxial cables are installed in tunnels and other scenarios, they are generally fixed on the side of the tunnel wall by means of clamps. From the perspective of installation and fixing methods, the leaky cable structures are mainly divided into two types: self-supporting and non-self-supporting. [0003] At present, leaky cables are used for wireless signal coverage in tunnels, mainly non-self-supporting leaky cables. The ...

AI Technical Summary

Problems solved by technology

The non-self-supporting leaky cable cannot bear the load through its own structure, and it is completely dependent on fixtures for installation. Generally, one fixture is installed at an interval of one meter to fix the entire leaky cable. There are the following technical problems: 1. The fixture density is high, and every Holes need to be drilled on the tunnel wall at intervals of one meter. The construction cost is high, time-consuming and labor-intensive, and the construction period is long; 2. Intensive drilling will affect the structural strength of the wall; 3. There are many fixtures and maintenance in the later stage During the work, the number of inspections is very large; 4. The whole leaky cable cannot be tightened by only relying on the clamps for bearing, and the straightness of the whole leaky cable cannot be guaranteed after installation; The expansion and contraction of the leaky cable, as well as the vibration of the leaky cable caused by the wind load or the vibration of the wall, will affect the force between the leaky cable and the fixture, causing the leaky cable to loosen; 6. Affected by the force of the tunnel wind tunnel effect , the leaky cable will be displaced relative to the fixture in its axial direction, causing potential safety hazards
