Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to fire-resistant and fire-proof special cables and cable installation equipment. Background Art

[0002] High temperature resistant and fire resistant cables for special equipment are mainly used in power transmission and control systems in special environments such as nuclear power equipment, large power distribution systems of buildings, petrochemical industry, ships, aircraft, rail transportation, automobile manufacturing, etc. under high temperature, high pressure, flammable and explosive conditions.

[0003] Most fire-resistant and fireproof cables on the market generally use mica tape wound on the conductor as a fire-resistant layer. Since mica itself is a high-hardness hexagonal sheet or plate, occasionally columnar, layered structure, monoclinic system, it is easy to break when bent. During installation, the cable is easily damaged, resulting in loss of fire resistance. There are also some mineral fire-resistant cables with outer layers, most of which use metal armor to protect the stability of the internal structure of the cable. However, the cable structure of the metal armor is large in size and the unit cable itself is relatively heavy. During operation, it is heavy and labor-intensive, which is not convenient for construction operations.

[0004] To this end, the present invention provides fire-resistant and fire-proof special cables and cable installation equipment. Summary of the Invention

The outer wall of the driving wheel 803 is engaged with the driven wheel 8; the second servo motor 801 drives the driving rod 802 to rotate, thereby driving the driving wheel 803 to drive the movable plate 203 connected to the driven wheel 8 to rotate on the inner wall of the annular plate 201, and then can drive the three clamping plates 3 to rotate counterclockwise, so that the damaged areas on the outer wall of the cable core 1 are coated with glue, smoothed with glue, and air-dried with glue in turn.

By providing two guide plates 901, the front and rear ends of the damaged part of the cable core 1 can be lifted and guided, thereby avoiding excessive bending of the damaged part of the cable core 1 during repair, thereby playing a protective role.

[0068] Working principle: The cable core 1 is placed as a whole along the guide plate 901 into the first cable groove 204, and the worm 7064 is driven to rotate by the first servo motor 7063, so that the worm 7064 drives the worm wheel 7061 to rotate, and the worm wheel 7061 drives the limit plate 703 to rotate, and the limit groove 705 rotates synchronously, thereby driving the limit rod 702 inside the limit groove 705 to slide, so that the limit rod 702 drives the movable rod 301 to slide inside the slide groove 701, so that the three splints 3 move synchronously until they fit the outer wall of the cable core 1, thereby positioning the cable core 1;

[0069] The second servo motor 801 drives the driving rod 802 to rotate, so that the driving rod 802 drives the driving wheel 803 to rotate, so that the driving wheel 803 drives the movable plate 203 connected to the driven wheel 8 to rotate inside the annular plate 201, so that the three clamping plates 3 inside the movable plate 203 rotate counterclockwise on the outer wall of the cable core 1, so that the glue coating component 4 on the clamping plate 3 first coats the outer wall of the cable core 1 with glue, and the flexible scraper 5 scrapes the glue flat, and then the blowing component 6 blows the flattened glue to dry it;

[0070] The following are the steps of applying glue, scraping glue, and air-drying glue on damaged areas of the outer wall of the cable core 1 by rotating the three splints 3 counterclockwise:

[0071] The glue in the glue storage tank 404 is extracted by the water pump 405 and enters the first corrugated tube 403. The glue enters the inside of the splint 3 through the movable rod 301 until it flows out through the glue outlet 402. Under the action of the first one-way valve inside the glue outlet 402, the glue can be prevented from flowing back into the inside of the splint 3. The squeezed glue is coated on the outer wall of the cable core 1 along the groove of the glue coating groove 401, so that the damaged part of the outer wall of the cable core 1 can be repaired. When the glue in the glue storage tank 404 is insufficient, the glue storage tank 404 can be filled with glue by opening the plug inside the glue filling port 406.

[0072] After the glue is applied to the damaged part of the outer wall of the cable core 1 by the glue coating component 4, the flexible scraper 5 on the next clamping plate 3 will scrape the applied glue to ensure that the glue is evenly covered on the cable surface to avoid uneven thickness, thereby improving the protection effect. Scraping can help expel bubbles in the glue to prevent bubbles from forming weak points after curing and affecting the overall performance of the cable;

[0073] After the flexible scraper 5 has scraped the glue flat, when the next splint 3 rotates to the area where the glue is scraped flat, the hot air blower 602 is turned on to supply air to the inside of the second corrugated tube 601. The air flow enters the inside of the splint 3 along the movable rod 301 and is then ejected through the air outlet 603, thereby air-drying the scraped glue. By providing a spacer 604, the splint 3 can maintain a certain distance from the outer wall of the cable core 1 to avoid direct contact of the glue on the surface of the splint 3, thereby maintaining the air flow.

[0074] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
