Description

Collecting line structure and manufacturing method thereof

Technical Field

The invention belongs to the field of communication antennas, and particularly relates to a novel assembly line structure and a manufacturing method thereof, which can be used as assembly line parts of large-scale line antennas such as horizontal log periodic antennas, fish bone antennas and the like.

Background

With the improvement of society and the improvement of technical level, the requirement on the use reliability of large-scale line antennas is also higher and higher, and it is hoped that a plurality of antenna sets can be synthesized in the air, and the electrical performance of the antenna is ensured not to be weakened with the passage of time. At present, the material adopted by the assembly line parts of large-scale line antennas such as horizontal log periodic antennas is mainly stainless steel wire ropes (the structural form is shown in figure 1), points are marked on the stainless steel wire ropes (the structural form is shown in figure 2), and the assembly line parts are in threaded connection with the components such as vibrators, jumpers and the like in site by adopting a copper-pressed sheet threaded connection mode. Because the elastic deformation of the stainless steel wire rope is larger, the assembly lines of the same two antennas cannot be ensured to be equal in length and even greatly different due to the influence of external load and operation level of operators in the manufacturing process, and the actual effect of antenna synthesis is seriously influenced; and under the effect of on-site wind load, copper preforming threaded connection mode increases the uniformity along with the time and declines, and threaded connection position can appear not hard up phenomenon, and antenna connection is insecure, forms the virtual phenomenon, makes the overall performance of antenna decline.

Disclosure of Invention

The invention aims to provide a novel collection line structure and a manufacturing method thereof.

The invention adopts the following technical scheme:

in a novel collective line structure, the improvement comprising: the stainless steel wire winding device comprises stainless steel stranded wires and feed press sleeves which are connected to the stainless steel stranded wires in series, wherein the number of the feed press sleeves is set according to the requirement, and the feed press sleeves are welded to the set installation positions on the stainless steel stranded wires in a silver welding mode.

The novel method for manufacturing the collection line structure is used for manufacturing the novel collection line structure and is improved in that the method comprises the following steps:

step 1, selecting the same batch of stainless steel stranded wires with the same specification, blanking, aging for 30 minutes under the condition of pulling wires with 2/3 rated load, and aging for 7 days in a relaxed state after force unloading;

step 2, the stainless steel stranded wires processed in the step 1 are unfolded on a flat ground, a required number of feed voltage sleeves are connected in series with the stainless steel stranded wires, a 3T tension meter is connected in series with the stainless steel stranded wires, the force is slowly applied to the antenna assembly line to simulate and calculate the force value, the force value is kept unchanged, a hundred-meter tape with 15kg tension is utilized to mark the installation position of each feed voltage sleeve as required, the time is not more than 2 hours, and the force unloading of the stainless steel stranded wires is relaxed after the completion;

step 3, crimping each feed press sleeve to the installation position on the stainless steel twisted wire by using a crimping pliers in a loose state, and silver soldering at the waist-shaped hole position of the feed press sleeve;

and 4, connecting the 3T tension meter and the stainless steel stranded wire in series again at intervals of not less than 72 hours with the step 2, slowly applying force to the antenna assembly line to simulate and calculate the force value, keeping the force value unchanged, verifying and recording the welding position of each feed pressure sleeve by using a hundred-meter measuring tape with 15kg tension, and loosening the force unloading of the stainless steel stranded wire after the end.

The beneficial effects of the invention are as follows:

the novel assembly line structure disclosed by the invention has the advantages of simple principle, feasible technology and convenience in application. Compared with the threaded connection mode of the stainless steel wire rope, the assembly line has good structural consistency, firm connection and small influence by operators and operation processes.

The novel method for manufacturing the assembly line structure disclosed by the invention is easy to grasp and implement by a person skilled in the art, and can solve the problems of large consistency deviation and connection looseness of the assembly line of the conventional stainless steel wire rope so as to achieve the optimal performance of the antenna. The method can be applied to the integrated line structure of the line antenna and can be widely applied to the field of other connection structures of the line antenna.
