In the existing submarine cable production, asphalt filling is carried out in an armor wire gap. Asphalt is poured onto the cable from the asphalt cylinder through the asphalt spray nozzle by the pump, so that the uniformity of asphalt coating cannot be ensured, and the copper belt is broken when the cable core passes through the drawing die in order to prevent the cable core from being excessively large in outer diameter due to asphalt coating, so that an asphalt scraping device is needed to scrape excessive asphalt on the cable core.

The asphalt scraping tool used at the present stage mainly comprises a die and a rubber plate;

The asphalt is scraped by the mould, and in order to ensure that the cable core within the tolerance range can pass through the mould, the inner diameter of the mould is required to be slightly larger than the positive deviation of the outer diameter of the cable core, so that the scraping effect of the mould on the asphalt is poor; in the production process of the submarine cable with a large length, asphalt is remained on the inner wall of the die, and the asphalt is cooled and solidified during shutdown, so that the cable core is clamped in the die, and the production is affected.

The condition that the inner wall is blocked by asphalt is avoided when the asphalt is scraped by the rubber plate, but the rubber plate is low in hardness and insufficient in scraping strength; in the production process of the submarine cable with large length, the aperture of the rubber plate is worn and increased continuously, so that the situation that the rubber plate needs to be frequently stopped and replaced is caused, and the production efficiency is affected

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1 and 2, an asphalt scraping apparatus, comprising:

The frame body 1 is provided with a cable core preheater 2 and a tensioning assembly 3 in sequence along the optical cable advancing direction; the tensioning assembly 3 has two connection blocks; a working space is formed between the two connecting blocks, and the connecting line of the center points of the two connecting blocks is perpendicular to the advancing direction of the optical cable;

the linear scraping member 4 includes a curved portion 400, the curved portion 400 forming a circular scraping space, one end of the curved portion 400 being connected to one of the connection blocks through a straight portion 401, and the other end being also connected to the other connection block through a straight portion 401.

When in use, the cable core preheater 2 heats the asphalt of the cable core to soften the asphalt for convenient subsequent scraping, and then the redundant asphalt is scraped after the optical cable passes through the round scraping space formed by the bending part 400; wherein, the circular scraping space can ensure the scraping uniformity; the tensioning assembly 3 enables the straight line part 401 of the linear scraping piece 4 to be straightened and tightened, so that the position of the bending part 400 is unchanged after the bending part contacts asphalt, namely after the bending part is stressed, the asphalt can be scraped, and the scraping force is ensured by the tensioning assembly 3; in addition, the scraping part is formed by the linear windings, and the working surface is a round winding asphalt which can not influence the scraping effect at the later stage even if the asphalt remains.

It should be understood that: the direction of travel of the cable is the direction of cable payoff travel, as indicated by reference a in fig. 1.

Referring to fig. 4 and 5, reference B is a cable core or a cable, and the projection of the bending part 400 on the horizontal plane is a circle, and the two ends of the circle are not butted, but have a displacement difference in the traveling direction of the cable; the curvature 400 should be a rigid and flexible material that can deform under force, the diameter of the circular scraping space being adjustable by the tensioning assembly 3. The diameter of the circular scraping space formed by the bending part 400 during the scraping operation is equal to the diameter required to be remained after the cable is scraped. That is, the shape of the bent portion 400 is required to be fixed, and the circular scraping space has a maximum deformation amount when being tensioned or strained; the purpose is to ensure that the circular scratch space of the bent portion 400 does not vary with the size of the cable during the scratch process. The optical cable used is an inner armor cable which needs to be coated with asphalt.

In some preferred embodiments, to achieve the scraping action of the linear scraper 4 described above, there are two forms:

first, the bending part 400 is made of metal material, and the straight line part 401 is a high temperature resistant pull rope;

Second, both the bent portion 400 and the straight portion 401 are made of a metal material. The linear scraping element 4 can be regarded as a steel rope with a special structure and has the characteristics of high temperature resistance, high hardness and wear resistance.

Secondly, the tensioning assembly 3 comprises two bearing seats, the distribution direction of which is parallel to the linear part 401, and the bearing seats are provided with guide holes and threaded holes which are arranged at intervals in the advancing direction of the optical cable; the two bearing seats are respectively connected with a guide rod and a screw rod through a guide hole and a threaded hole; the screw rod is connected with a driving motor; the tensioning assembly 3 further comprises a movable seat, and a threaded hole guide hole is also formed in the movable seat; one of the connecting blocks is fixedly arranged on one of the bearing seats, and the other connecting block is fixedly arranged on the movable seat.

In the above two ways, both straight portions 401 are connected with the corresponding moving blocks through the tension meters 5; the tension meter 5 measures tension by measuring a tension difference between the two straight portions 401. It is of course also possible to replace the tension meter 5 directly with a tension sensor, but this is limited by the type and type of tension sensor and is also expensive.

Therefore, the tension tensioning assembly 3 can change the tension of the linear scraping piece 4 by reading in real time, so as to change the round scraping space, and the scraping force can be adjusted at any time according to actual conditions to control the asphalt scraping effect.

Further, when the optical cable or the cable core is too large, and passes through the set circular scraping space, the linear scraping element 4 is greatly deviated, and a certain production risk exists, so that the risk needs to be monitored, and the following settings can be referred to:

The straight line part 401 is connected with the tension meter 5 through an angle detection piece 6; the frame body 1 is also provided with an alarm device 9, and the alarm device 9 is in signal connection with the angle detection piece 6 and is used for giving an alarm when the angle change value is detected to exceed a threshold value; the cable core is too big and can trigger alarm device and report to the police, reminds the production personnel to in time handle production risk.

Wherein, the angle detecting piece 6 comprises a straight rod, one end of the straight rod is provided with a connecting ring connected with the straight line part 401, and the other end is hinged with the detecting end of the tension meter 5; and a gyroscope is arranged on the straight rod. The gyroscope can be used for detecting the angle change, and is not excessively explained for the prior art.

In some preferred embodiments, to facilitate the collection of scraped asphalt, the present arrangement is based on the second mode of the tensioning assembly 3 above:

The number of the tensioning assemblies 3 is a plurality, and the tensioning assemblies are arranged at intervals along the travelling direction of the optical cable; the tensioning assemblies 3 are independently arranged, so that a certain linear scraping piece 4 can be replaced without stopping after being worn and broken, and the scraping effect is kept unchanged all the time and the production progress is not influenced.

An asphalt collecting box is arranged on the frame body 1, and a plurality of waste material inlet openings are arranged on the asphalt collecting box; a plurality of tensioning assemblies 3 are mounted on top of the asphalt collection bin; the projection of the guide rods and the screw rods in each tensioning assembly 3 on top of the asphalt collection box is located on both sides of the waste entry opening, which are both sides of the direction of travel of the cable.

The temperature detection part and the first heating part are arranged in the asphalt collection box and are respectively used for heating asphalt in the asphalt collection box, and the temperature of the asphalt in the box is detected in real time, so that the asphalt is ensured to be in a molten state and can be discharged; the asphalt collecting box is also provided with an asphalt return pipe 7, and the asphalt return pipe 7 is provided with a discharge valve 8.
