Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, specifically to a processing method and apparatus for a heat-insulated mineral-insulated fireproof cable. Background Technology

[0002] In modern buildings, industrial facilities, energy transmission, and various scenarios with extremely high fire safety requirements, mineral-insulated fire-resistant cables play an indispensable role. With the acceleration of urbanization and the increase in large and complex buildings, such as high-rise buildings, underground rail transit, and large commercial complexes, ensuring the continuity of power supply to fire-fighting equipment and critical systems is crucial in the event of a fire. Mineral-insulated fire-resistant cables, with their superior fire-resistant performance, can maintain energization for extended periods in high-temperature and even flame environments, providing reliable power for personnel evacuation, fire rescue, and the operation of critical equipment, thus becoming a vital line of defense for protecting life and property.

[0003] In the production process of mineral-insulated fire-resistant cables, cutting and inspection are crucial steps. Traditional cable cutting and inspection methods have many limitations, making it difficult to meet the efficiency, quality, and precision requirements of modern production. Traditional cutting methods often fail to guarantee the flatness and smoothness of the cut surface. Burrs and unevenness may occur during the cutting process, which not only affects the appearance quality of the cable but may also adversely affect subsequent inspection and use. Uneven cut surfaces may lead to inaccurate observation of the cable's internal structure during inspection, affecting quality judgment. During cable installation, burrs may scratch other components or cause poor contact. Different specifications and lengths of mineral-insulated fire-resistant cables require different cutting lengths during production. Traditional cutting equipment is difficult to adjust, making it difficult to flexibly adjust the cutting length according to actual needs, resulting in poor equipment applicability and an inability to meet diverse production requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a processing method and apparatus for heat-insulated mineral-insulated fireproof cables, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a processing device for heat-insulating mineral-insulated fireproof cables, comprising a cutting table, a driving component installed at the bottom of the cutting table, a cutting component installed on one side of the cutting table, and a guide groove through the top of the cutting table.

The wire saw is movably mounted inside the protective slide, the protective bend, the sliding plate, and the movable sleeve, wherein the two movable sleeves are slidably mounted on the inner sides of the two ends of the guide groove.

[0007] Preferably, a second sliding frame is fixedly installed on the top and bottom of the mounting plate on the side away from the protective frame. A fixed connecting rod is fixedly installed on both sides of the second sliding frame. A first sliding frame is fixedly installed on the end of the fixed connecting rod away from the second sliding frame. A sliding block is slidably installed inside the first sliding frame. One side of the sliding block is fixedly connected to the side of the sliding plate where the movable sleeve is installed. A second rectangular slot is opened on one side of the first sliding frame. A sliding strip is fixedly installed on one side of the sliding block. The sliding strip is slidably installed inside the second rectangular slot and the protective bend.

[0008] Preferably, connecting bending plates are fixedly installed on the bottom of both sides of the mounting plate, and a moving block is fixedly installed on the end of the connecting bending plate away from the mounting plate. Moving slots are opened on both sides of the cutting table, and the moving blocks are slidably installed inside the moving slots.

[0009] Preferably, a drive plate is fixedly installed on both sides of one of the sliding frames, and one of the two drive plates has a threaded hole and the other has a sliding hole.

[0010] Preferably, the drive assembly includes a slide rod and a threaded rod. A first fixing plate is rotatably mounted on both ends of the slide rod and one end of the threaded rod. The top of the first fixing plate is fixedly connected to the bottom of the cutting table. A second fixing plate is rotatably mounted on the end of the threaded rod away from the first fixing plate. A drive motor is fixedly mounted on one side of the second fixing plate. The output end of the drive motor is fixedly connected to one end of the threaded rod. The threaded rod is threaded into the inside of a threaded hole, and the first fixing plate is slidably mounted inside the sliding hole.

[0011] Preferably, four outer sliding strips are fixedly installed on the outer side of the rotating shaft, and each of the transmission wheels has a sleeve groove inside. The transmission wheel is sleeved and installed on the outer side of the rotating shaft through the sleeve groove. Four sliding grooves are opened on the inner side of the sleeve groove. The four outer sliding strips are slidably installed on the inner side of the four sliding grooves respectively. Protective baffles are fixedly installed on both sides of the outer side of the transmission wheel.

[0012] Preferably, the bottom of the cutting table is fixedly equipped with support legs, and there are four support legs.

[0013] A method for using a processing apparatus for heat-insulated mineral-insulated fire-resistant cables includes the following steps:

[0014] S1; Conductor treatment: First, the conductor is cleaned by a multi-band ultrasonic cleaner at a temperature of 60 degrees Celsius for 5 minutes. After cleaning, it is dried in a hot air circulating drying oven at a temperature of 120 degrees Celsius for 30 minutes.

[0015] S2: Cable production: Magnesium hydroxide powder is mixed with glue and stirred into a paste. This paste is then applied to the outside of the conductor using a grouting machine to form a fire-resistant layer. The cable sheath is then fitted onto the outside of the fire-resistant layer, and an isolation skeleton is nested inside the cable sheath. An aluminum sheath is nested inside the isolation skeleton. Magnesium hydroxide powder is then mixed with glue and stirred into a paste. This paste is then filled between the aluminum sheath and the cable sheath using a grouting machine to form a fireproof layer. Finally, modified water glass-based inorganic gel is filled between the fireproof layer and the aluminum sheath to form the cable.

[0016] S3: Cable cutting inspection;

[0017] A1: Device Adjustment: Activate the drive assembly to move the cutting assembly outside the cutting table, bringing the wire saw closer to the cable. When the cutting assembly moves outside the cutting table, two of the moving sleeves can move inside the guide groove, allowing the moving sleeves to move along the path of the guide groove, thus moving the wire saw along the path of the guide groove. This adjusts the relative position between the two wire saws, thereby adjusting the length of the cut cable. Additionally, when the moving sleeves move inside the guide groove, the sliding plate can drive the sliding block to move inside the sliding frame, which in turn drives the protective slide block to move inside the rectangular through groove, allowing the transmission wheel to slide outside the rotating shaft through the sleeve groove, ensuring the wire saw is always taut.

[0018] A2: Cable Cutting: First, place the completed cable on top of the cutting table. Start the cutting motor. The output of the cutting motor can drive the rotating shaft to rotate, which in turn drives the transmission wheel to rotate through the cooperation of the outer slide bar and the sliding groove, thereby driving the wire saw and making the wire saw in a cyclical movement state. The wire saw is made of a special material with high strength and good wear resistance, and has good cutting characteristics. It can effectively cut the cable during high-speed movement. Then, the cable can be manually pushed to move closer to the wire saw, so that the two wire saws can cut off a section of the cable end for inspection. After that, it can be inspected.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the output end of the cutting motor can drive the rotating shaft to rotate, thereby driving the transmission wheel to rotate through the cooperation of the outer slide bar and the sliding groove, thus driving the wire saw and making the wire saw in a cyclic movement state. The wire saw is made of a special material with high strength and good wear resistance, and has good cutting characteristics. It can effectively cut the cable during high-speed movement. Afterwards, the cable can be manually pushed to move closer to the wire saw, so that the two wire saws can cut off a section of the cable end for inspection. Then, the cut cable section is inspected to visually check whether the insulation layer, sheath, conductor, etc. meet the design standards.

[0020] In addition, cutting with a wire saw is not only fast, allowing for simultaneous cutting of two cross sections, but also produces a smooth cut surface, facilitating subsequent inspection. Furthermore, cutting cables into segments not only increases the number of inspection ends but also makes it easier for operators to handle and store the cables. It also provides convenient conditions for other types of testing, such as mechanical and electrical performance testing.

[0021] In addition, by activating the drive assembly, the cutting assembly moves outside the cutting table, bringing the wire saw closer to the cable. When the cutting assembly moves outside the cutting table, two of the moving sleeves can move inside the guide groove, allowing the moving sleeves to move along the path of the guide groove, thus moving the wire saw along the path of the guide groove. This adjusts the relative position between the two wire saws, thereby adjusting the length of the cut cable. The adjustment method has the advantages of simple operation and a wide adjustment range, which can meet the cutting needs of cables of different specifications and greatly improve the applicability of the device.

Protective plates 17 are fixedly installed on the top and bottom of the protective frame 20. Rectangular through grooves 33 are opened inside the protective plates 17. Two protective slides 36 are slidably installed inside the rectangular through grooves 33. Protective bends 15 are fixedly installed on one side of the protective slides 36. Sliding plates 11 are fixedly installed on the end of the protective bends 15 away from the protective slides 36. Moving sleeves 29 are fixedly installed on the side of the sliding plates 11 away from the protective bends 15. The wire saw 7 is movably installed inside the protective slides 36, protective bends 15, sliding plates 11 and moving sleeves 29. The two moving sleeves 29 are slidably installed in the guide grooves 2. 4. On the inner sides of both ends, the top and bottom of the mounting plate 2 away from the protective frame 20 are fixedly installed with sliding frames 2 and 16. Fixed connecting rods are fixedly installed on both sides of the sliding frames 2 and 16. Sliding frames 1 and 13 are fixedly installed at the ends of the fixed connecting rods away from the sliding frames 2 and 16. Sliding blocks 12 are slidably installed inside the sliding frames 1 and 13. One side of each sliding block 12 is fixedly connected to the side of the sliding plate 11 where the movable sleeve 29 is installed. A rectangular through groove 2 and 10 are opened on one side of each sliding block 13. A sliding strip 14 is fixedly installed on one side of each sliding block 12. The sliding strip 14 is slidably installed inside the rectangular through groove 2 and the protective bend 15. Connecting bending plates 8 are fixedly installed on the bottom of both sides of the plate 2. Moving blocks 30 are fixedly installed on the ends of the connecting bending plates 8 away from the mounting plate 2. Moving slots 3 are opened on both sides of the cutting table 1. Moving blocks 30 are slidably installed inside the moving slots 3. Four outer sliding strips 23 are fixedly installed on the outer side of the rotating shaft 22. The transmission wheel 18 is provided with a sleeve groove 34 inside. The transmission wheel 18 is sleeved and installed on the outer side of the rotating shaft 22 through the sleeve groove 34. Four sliding grooves 35 are opened on the inner side of the sleeve groove 34. The four outer sliding strips 23 are slidably installed on the inner side of the four sliding grooves 35 respectively. Protective baffles 21 are fixedly installed on both sides of the outer side of the transmission wheel 18.

[0031] The working principle of the above technical solution is as follows: During use, the completed cable is placed on top of the cutting table 1. Then, the cutting motor 19 is started. The output of the cutting motor 19 drives the rotating shaft 22 to rotate, which in turn drives the transmission wheel 18 to rotate through the cooperation of the outer slide bar 23 and the sliding groove 35. This drives the wire saw 7, causing it to move in a cyclical state. The wire saw 7 is made of a special material with high strength and good wear resistance, possessing excellent cutting characteristics and capable of effectively cutting the cable during high-speed movement. Afterwards, the cable can be manually pushed towards the wire saw 7, thereby allowing the two wire saws 7 to cut the sampled portion of the cable end. A section of the cable is cut, and then the cross-section of the cut cable section is inspected to visually check whether the insulation layer, sheath, conductor, etc. meet the design standards. The cable is cut using a wire saw 7, which is not only fast, allowing for simultaneous cutting of two sections, but also produces a smooth cut surface, facilitating subsequent inspections. Cutting the cable into sections not only increases the number of inspection ends but also makes it easier for operators to handle and store the cable. It also provides convenient conditions for other types of testing, such as mechanical and electrical performance testing. Then, the drive assembly can be activated, causing the cutting assembly to move outside the cutting table 1, bringing the wire saw 7 closer to the cable. When moving, two of the movable sleeves 29 can move inside the guide groove 24, causing the movable sleeves 29 to move along the path of the guide groove 24, thereby causing the wire saw 7 to move along the path of the guide groove 24. This adjusts the relative position between the two wire saws 7, thus adjusting the length of the cut cable. The adjustment method has the advantages of simple operation and a large adjustment range, which can meet the cutting needs of cables of different specifications and greatly improve the applicability of the device. In addition, when the movable sleeves 29 move inside the guide groove 24, the sliding plate 11 can drive the sliding block 12 to move inside the sliding frame 13, thereby driving the protective bend 15 to move the protective The slide block 36 moves inside the rectangular through slot 33, allowing the transmission wheel 18 to slide on the outside of the rotating shaft 22 via the sleeve slot 34. This ensures that the wire saw 7 is always taut, thereby ensuring the stability and consistency of the cutting effect. In addition, the guide slot 24 ensures the accuracy and stability during processing and adjustment, allowing the cutting assembly to always move along the predetermined path without external interference. At the same time, the guide slot 24 has high structural strength and can withstand various forces generated during the cutting process, ensuring the stability of the cutting assembly during movement. This ensures that high accuracy and stability can be achieved during processing, meeting the quality requirements of cable cutting.

[0032] In another implementation scheme, such as Figures 1-6As shown, a drive plate 28 is fixedly installed on both sides of one of the sliding frames 13. The two drive plates 28 are respectively provided with threaded holes 31 and sliding holes 32. The drive assembly includes a slide rod 5 and a threaded rod 27. Fixed plates 4 are rotatably installed on both ends of the slide rod 5 and one end of the threaded rod 27. The top of the fixed plate 4 is fixedly connected to the bottom of the cutting table 1. Fixed plate 25 is rotatably installed on the end of the threaded rod 27 away from the fixed plate 4. A drive motor 26 is fixedly installed on one side of the fixed plate 25. The output end of the drive motor 26 is fixedly connected to one end of the threaded rod 27. The threaded rod 27 is threadedly connected inside the threaded hole 31. Fixed plate 4 is slidably installed inside the sliding hole 32.

[0033] After the drive motor 26 is started, it can drive the threaded rod 27 to rotate, thereby causing the drive plate 28 to move outside the guide groove 24 through the threaded hole 31, and causing another drive plate 28 to slide outside the fixed plate 4 through the sliding hole 32, thereby driving the sliding frame 13 fixedly connected to the drive plate 28 to move, thereby causing the cutting assembly to move outside the cutting table 1, thereby realizing the cutting of the cable.

[0034] In another implementation scheme, such as Figures 1-6 As shown, the bottom of the cutting table 1 is fixedly equipped with support legs 6, and there are four support legs 6.

[0035] The four support legs 6 provide overall support for the device, making it easy to place it in the desired location.

[0036] A method for using a processing apparatus for heat-insulated mineral-insulated fire-resistant cables includes the following steps:

[0037] S1; Conductor treatment: First, the conductor is cleaned by a multi-band ultrasonic cleaner at a temperature of 60 degrees Celsius for 5 minutes. After cleaning, it is dried in a hot air circulating drying oven at a temperature of 120 degrees Celsius for 30 minutes.

[0038] S2: Cable production: Magnesium hydroxide powder is mixed with glue and stirred into a mud-like consistency. This mud-like consistency is then applied to the outside of the conductor using a grouting machine to form a fire-resistant layer. The cable sheath is then fitted onto the outside of the fire-resistant layer, and an isolation skeleton is nested inside the cable sheath. An aluminum sheath is nested inside the isolation skeleton. Magnesium hydroxide powder is then mixed with glue and stirred into a mud-like consistency. This mud-like consistency is then filled between the aluminum sheath and the cable sheath using a grouting machine to form a fireproof layer. Finally, modified water glass-based inorganic gel is filled between the fireproof layer and the aluminum sheath to form a cable.

[0039] S3: Cable cutting inspection;

[0040] A1: Device Adjustment: Start the drive assembly to move the cutting assembly outside the cutting table 1, bringing the wire saw 7 closer to the cable. When the cutting assembly moves outside the cutting table 1, two of the moving sleeves 29 can move inside the guide groove 24, allowing the moving sleeves 29 to move along the path of the guide groove 24, thus moving the wire saw 7 along the path of the guide groove 24. This adjusts the relative position between the two wire saws 7, thereby adjusting the length of the cut cable. In addition, when the moving sleeves 29 move inside the guide groove 24, the sliding block 12 can be moved inside the sliding frame 13 via the sliding plate 11, thereby moving the protective slide 36 inside the rectangular through groove 33 via the protective bend 15, thus allowing the transmission wheel 18 to slide outside the rotating shaft 22 via the sleeve groove 34, ensuring that the wire saw 7 is always in a taut state.

[0041] A2: Cable Cutting: First, place the completed cable on top of the cutting table 1. Start the cutting motor. The output of the cutting motor 19 can drive the rotating shaft 22 to rotate, which in turn drives the transmission wheel 18 to rotate through the cooperation of the outer slide bar 23 and the sliding groove 35. This drives the wire saw 7, making the wire saw 7 in a cyclical movement state. The wire saw 7 is made of a special material with high strength and good wear resistance, and has good cutting characteristics. It can effectively cut the cable during high-speed movement. Afterwards, the cable can be manually pushed to move closer to the wire saw 7, so that the two wire saws 7 can cut off a section of the cable end for inspection. After that, it can be inspected.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
