Abstract
The utility model relates to an optical cable coiling and uncoiling device, and the technical problem which needs to be resolved is to provide a portable knapsack optical cable coiling and uncoiling device with a reasonable structure. The utility model is mainly composed of a coiling and uncoiling cable coil with an axle, a set of cable coil brackets with a cable coil bearing mechanism and a backpacking mechanism, and a cable coiling handle. Due to the reasonable design, the knapsack optical cable coiling and uncoiling device has the advantages of compact structure, light weight and reliable strength. Compared with various prior domestic field optical cable coiling and uncoiling devices, the utility model is characterized in small volume, light weight, relatively large capacity and good mobile performance.
Description
Technical field
The utility model belongs to and relates to the draw off gear that is used under a kind of lowered in field environment condition promptly laying with the rolling optical cable in the optical communication field.
Technical background
Draw occasions such as welding system, rescue and relief work optical cable transmission system and need use optical fiber cable for field operation repeatedly at regional electronics synthesis communication system, emergent opening.Optical fiber cable for field operation not only possesses the basic characteristics of ordinary optical cable, and can bear enough big tension load under the field operations environmental baseline, and the folding and unfolding of can also reeling repeatedly also has characteristics such as size is less, softness is light and handy on the structure.
For optical fiber cable for field operation can be used repeatedly, must be equipped with convenient, practical optical cable draw off gear.
During the State's Eighth Five-Year Plan period, it is carrier with the plain edition motor tricycle that the applicant has designed a kind of, lays fast and the device of rolling optical fiber cable for field operation.Though this device lay and rolling speed very fast, higher to the road conditions conditional request, thereby can't satisfy the requirement of folding and unfolding optical cable under the complicated physical environment in the open air.
During the State's Ninth Five-Year Plan period, the applicant has designed a kind of open-air optical cable retractable frame device again.This device is furnished with the unwrapping wire arrestment mechanism and receives around wire-arranging mechanism.At ordinary times, the retractable frame of this device can fold, so that storage and transportation.During use, retractable frame can be propped up the triangularity structure and be placed on the vehicle and move; Move or push-and-pull by lifting more than two people after also it can being extended into in-line.But himself quality is bigger, loads limit load behind the optical cable up to 55 kilograms, thereby must be with vehicle-mounted or cooperate more than two people and can carry out the optical cable folding and unfolding.Under the lowered in field environment, this will have a strong impact on the maneuverability of optical fiber cable for field operation folding and unfolding.
Domestic also have the lighter portable actinobacillus device of weight, but its length of holding optical fiber cable for field operation is too short, makes the total losses that continue of optical cable too big.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, and can carry out portable backpack optical cable draw off gear to the optical cable draw off gear.It not only wants compact conformation, body is light and handy, intensity is reliable, and compares with domestic existing various optical fiber cable for field operation draw off gears, and it is must volume little, in light weight, relative capacity is big, mobility good.
The utility model solves above technical matters by the following technical programs.
