Description
Technical field
The present invention relates to a kind of line holder of network equipment installation, particularly a kind of curved line holder.
Background technology
The 3G (Third Generation) Moblie TD-SCDMA technology, as the first 3G (Third Generation) Moblie international standard with independent intellectual property right of China, adopted a lot of technology such as smart antenna, time-division and code minute technology, uplink synchronous, up-downgoing be asymmetric, and these technology to be the characteristic service application of TD-SCDMA brought original advantage.The 3G (Third Generation) Moblie TD-SCDMA technology began trial run in 2007, whole nation provincial capital will carry out the second stage of the project in the end of the year 2008, the third stage of the project was built in the beginning nationwide in 2010, its construction speed is unprecedented, as the brand-new communication technology of a generation, comprised a large amount of new equipment, its construction technology, construction method and previous generation mobile communication technology are very different and improve.
The TD-SCDMA base station architecture is taked and 2G(Generation Mobile Telecommunication System network, the GSM network) the diverse framework in base station, TD-SCDMA have adopted the base station BBU(Building Base band Unit: Base Band Unit)+RRU(Remote Radio Unite: remote radio unit (RRU)) framework.BBU equipment generally is installed in the machine room, and RRU equipment generally is installed on the outer communication tower of machine room, and BBU is connected by optical cable with RRU and realizes communication, so the effect of optical cable of BBU and RRU of connecting is of crucial importance.The kind of base station communication steel tower is a lot, and is wherein more with the quantity of only shaft tower.Therefore how better to protect optical cable, it is the background of this product of research and development that reliable wireless signal is provided.
At the beginning of TD-SCDMA builds, what engineering construction was mainly used for reference is the construction method of Generation Mobile Telecommunication System (GSM), but because the TD-SCDMA base station is very different with the principle of GSM base station: what be connected antenna and equipment in the GSM base station is to only have feeder line, what connect antenna and equipment in the TD-SCDMA base station has comprised optical cable and power lead, the intensity of feeder line ultraphotic cable far away, be convenient to install, and the weight of optical cable is greater than feeder line, add the weight of power lead, will produce some problems if continue to use the construction method of GSM.
Especially large bending angle passes the position of only shaft tower at optical cable and power lead, owing to gravity can make optical cable and power lead produce very large bending angle, and so can cause the damage of optical cable, and then affect the use of base station.The present invention then can solve these above problems.
Summary of the invention

Embodiment
Below in conjunction with Figure of description the invention is described in further detail.
Embodiment one
In the present embodiment one, the concrete steps of 3 G mobile communication network TD-SCDMA base station only shaft tower BBU-RRU optical cable construction method as shown in Figure 1, its implementation step is:
The first step: the optical cable of unpacking;
Select the optical cable of appropriate length.Connect the BBU-RRU optical cable because considering the requirement to transmission quality, all be to adopt the fixed length optical cable, whether the length of each required optical cable in base station is stipulated by design document, needs optical cable is carried out following check before therefore installing: 1. check the cable length that arrives the working-yard to conform to design document; 2. the presentation quality of check optical cable has the optical cable of appearance quality to forbid installing; 3. check the A of optical cable, the quality of B end connector part, an end that is used for connecting RRU is called the A end, and an end that is used for connecting BBU is the B end, and whether check that joint is whether intact has an attachment etc.;
Second step: make optical cable in order, carry out interim label;
Before laying optical cable, must make optical cable in order, prevent from laying process, causing the situations such as optical cable kink, knotting, winding, for the correct sector of distinguishing, must carry out interim label before the optical cable laying simultaneously;
The 3rd step: the A port (port that links to each other with RRU) to optical cable carries out necessary protection;
A port (port that links to each other with RRU) for the protection optical cable, before the lifting optical cable, need A port (port that links to each other with RRU) is carried out necessary protection, salvo comprises uses firm cloth or grog paper bag to wrap up in A port (port that links to each other with RRU) etc., wants colligation firm after requiring to wrap;
The 4th step: the curved line holder is installed;
Line outlet place on tower, select suitable position to install and fix " curved line holder ", installation requirement: 1. sufficient space is reserved for the optical cable cabling in curved line holder top; 2. the arc mid point of curved line holder is the most better; 3. each securing member will be installed firmly; 4. when regulating the two ends stationary installation, need guarantee two ends stationary installation even regulation, to guarantee the two ends stress balance;
The 5th step: lifting optical cable;
Personnel will lift with rope and put down from the line outlet on the tower on the tower, and personnel pull out rope from the incoming line under the tower under the tower, and will be with rope that the A end colligation of optical cable is good.Personnel lift by crane optical cable on the tower, and personnel carry optical cable to line inlet port under the tower, and the librarian use intercom is coordinated operation on the tower, under the tower, and synchronous operation requires lifting speed unsuitable too fast, and tower is harmonious up and down;
The 6th step: fixing optical cable;
On the tower personnel the optical cable of reserving sufficient length be used for being connected of RRU after, carry out colligation to optical cable and fix.Require: 1. optical cable closely connected the clothes on the arcwall face of curved line holder that be critical; 2. with the cavity of binding strap by the curved surfaces of " curved line holder ", optical cable is carried out colligation; 3. adjust in case of necessity " curved line holder " position, make to install to reach best effects;
The 7th step: optical cable is connected respectively with BBU, RRU.
According to construction method of the present invention, optical cable is connected with BBU, RRU respectively, wherein the A end connects RRU, and the B end connects BBU, checks simultaneously good prior ready-made label, has distinguished the BBU of three sectors, base station and the corresponding relation of RRU.
Wherein, also comprise at the second step of implementation method of the present invention with between the 3rd step: 1. erecting optical cables disc carrier; 2. workmen Deng Ta on the tower.In order to make things convenient for the reel unwrapping wire, simple and easy reel support is set, guarantee to lay optical cable and make the stressed minimum of optical cable, can prevent also that simultaneously optical cable from placing when dragging on the ground and the friction on ground and stained optical cable.Carry the necessary instrument of construction when stepping on tower personnel Deng Ta, comprise that the lifting that lifts optical cable is with rope, intercom etc.
