Description

Technical Field

[0001] The present invention relates to the technical field of wire-drawing equipment, and specifically to a wire-drawing device for laying weak-current engineering lines and its usage method. Background Technique

[0002] Weak-current engineering is a classification of power applications. Power applications can be divided into strong current and weak current according to the strength of the power transmission. The electricity used in buildings and building complexes generally refers to weak current below 220V 50Hz, which mainly provides electrical energy to people and converts electrical energy into other forms of energy, such as air-conditioning power consumption, lighting power consumption, power for driving, etc. In the wiring of weak-current engineering, a wire-drawing device for laying lines is required, and then the lines are fixed through other items such as wire pipes for convenient use and operation. Generally, when winding cables, one end of the cable is basically connected to the object to be wound, and then the object to be wound is driven to rotate by an external power source to achieve the winding effect. When the cable is wound around the object, it will rotate synchronously with the rotation of the object, making it difficult to control the tension of the cable on the object to be wound well. It may cause the cable on the object to be wound to become slack due to excessive tension, affecting the tightness of the cable during wire-drawing, resulting in the cable being piled up due to slack, and affecting the overall efficiency of the cable wire-drawing work.

[0008] Furthermore, a cleaning mechanism is arranged between the two square plates. The cleaning mechanism includes two fixed discs fixedly connected to the outer surface of the crankshaft. An annular concave groove is formed on one side of the fixed disc close to the crankshaft. A swing block is slidably connected to the inside of the annular concave groove.

[0012] Furthermore, a method of using a wire pulling device for laying weak current engineering lines, the wire pulling device for laying weak current engineering lines, the method comprising the following steps: S1: First, pass the cable through the top of the limiting plate, then connect the cable to the first rotating column, and then start the motor. When the motor rotates, it will drive the first rotating column to rotate through the rotating belt. S2: At the same time, when the rotating belt rotates, it will drive the second rotating column to rotate. When the second rotating column rotates, it will drive the crankshaft to rotate together. Then, when the first rotating column rotates, it will play a role in pulling the cable.

[0013] The present invention has the following beneficial effects: (1) In the present invention, when the rotating belt rotates, it will drive the second rotating column to rotate. When the second rotating column rotates, it will drive the crankshaft to rotate together. When the crankshaft rotates, it will drive the rotating block to rotate together. Since the rotating block is rotatably connected to the crankshaft and the second rotating column and the rotating block are eccentrically arranged, when the second rotating column rotates, the rotating block will generate an up-and-down swing. When the rotating block makes an up-and-down swing, it will drive a plurality of swing rods on the top of the rotating block to swing up and down together. When the swing rods swing up and down, they will drive the spring rods to swing up and down together. When the spring rods swing up and down, they will drive the limiting plate to swing up and down together. When the limiting plate contacts the cable and applies an outward force, since the spring rods can adjust the height according to the magnitude of the tension, thereby changing the tension state of the cable, avoiding the situation of too large or too small tension when the cable is wound, reducing the excessive tension borne by the part with larger tension, and thus reducing the slack of the cable on the object being wound. In this way, the tightness of the cable during wire pulling is improved, and the situation of cable accumulation due to slack is reduced. This device improves the protection of the cable compared with the existing device and improves the overall performance of the cable during the next use.

[0014] 0. In the present invention, when the second rotating column rotates, it drives two fixed discs to rotate together. When the fixed discs rotate, the annular recessed grooves formed on the surfaces of the fixed discs cause the swing blocks to swing back and forth. When the swing blocks swing back and forth, they drive the long rods to swing together. When the long rods swing, they drive the third rotating column to swing together. When the cable passes through the outer surface of the abrasive belt, it drives the abrasive belt to rotate. When the abrasive belt rotates, it drives the first swing disc to rotate through the second square block and the crank rod. Since the rotating disc is fixedly connected to the long rod and the first swing disc is rotatably connected to the long rod, when the first swing disc rotates, several convex blocks on its surface intermittently contact the C-shaped convex blocks on the surface of the rotating disc, causing the first swing disc to swing back and forth. When the first swing disc swings back and forth, it causes the second swing disc to swing back and forth through the crank rod. When the second swing disc swings back and forth, it drives the abrasive belt to swing back and forth, thereby rubbing the dust and impurities on the surface of the cable, cleaning the impurities on the outer surface of the cable, reducing the wear caused by the friction of the impurities on the outer surface of the cable, and preventing the impurities from falling into the parts inside the adjusting mechanism and damaging the parts, thus reducing the service life of the device and improving the cable pulling efficiency.

[0015] 3. In the present invention, when the crank rod rotates around the long rod, it drives the second gear to rotate together. Since the first gear is fixedly connected to the long rod and the first gear meshes with several second gears, when several second gears rotate, they are blocked by the first gear and thus rotate. When the second gears rotate, they cause several pushing blocks to rotate together. The pushing blocks are arranged in a staggered manner, one above the other, and a first spring is fixedly connected between two staggered pushing blocks. A spring block is fixedly connected between the first springs. When the pushing blocks rotate, they cause the spring block to swing back and forth through the first spring, thereby vibrating and knocking the abrasive belt. The vibration causes the impurities and dust on the surface of the cable to fall off, further improving the protection of the cable, preventing the impurities from rubbing on the surface of the cable as the abrasive belt swings during friction and causing wear on the outer surface of the cable, and further enhancing the cleaning efficiency of the abrasive belt on the surface of the cable.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A usage method of a wire pulling device for weak current engineering line laying. For the wire pulling device for weak current engineering line laying, this method includes the following steps. S1: First, pass the cable through the top of the limit plate, then connect the cable to the rotating column one, and then start the motor. When the motor rotates, it will drive the rotating column one to rotate through the rotating belt. S2: At the same time, when the rotating belt rotates, it will drive the rotating column two to rotate. When the rotating column two rotates, it will drive the crankshaft to rotate together. Then, when the rotating column one rotates, it will play a role in pulling the cable.

[0030] During use, first pass the cable through the top of the limit plate 209, then connect the cable to the first rotating column 203. After that, start the motor 201. When the motor 201 rotates, it will drive the first rotating column 203 to rotate through the rotating belt 202. When the rotating belt 202 rotates, it will drive the second rotating column 204 to rotate. When the second rotating column 204 rotates, it will drive the crankshaft 205 to rotate together. When the crankshaft 205 rotates, it will drive the rotating block 206 to rotate together. Since the rotating block 206 is rotatably connected to the crankshaft 205 and the second rotating column 204 is eccentrically arranged with the rotating block 206, when the second rotating column 204 rotates, the rotating block 206 will swing up and down. When the rotating block 206 swings up and down, it will drive several swing rods 207 on the top of the rotating block 206 to swing up and down together. When the swing rods 207 swing up and down, they will drive the spring rod 208 to swing up and down together. When the spring rod 208 swings up and down, it will drive the limit plate 209 to swing up and down together. When the limit plate 209 exerts an outward force on the cable contact, since the spring rod 208 can adjust its height according to the size of the tension, thereby changing the tension state of the cable, avoiding the situation of too large or too small tension when the cable is wound, reducing the excessive tension on the part with larger tension, and thus reducing the slack of the cable on the object being wound. In this way, the tightness of the cable when pulling the cable is improved, and the situation of the cable piling up due to slack is reduced. This device improves the protection of the cable compared with the existing device and improves the overall performance of the cable when used next time.

[0031] When the second rotating column 204 rotates, it will drive the two fixed discs 301 to rotate together. When the fixed discs 301 rotate, the annular recessed grooves formed on the surfaces of the fixed discs 301 will cause the swing block 309 to swing back and forth. When the swing block 309 swings back and forth, it will drive the long rod to swing together. When the long rod swings, it will drive the third rotating column 302 to swing together. When the cable passes through the outer surface of the abrasive belt 307, it will drive the abrasive belt 307 to rotate. When the abrasive belt 307 rotates, it will drive the first swing disc 304 to rotate through the second square block 305 and the crank rod 306. Since the rotating disc 303 is fixedly connected to the long rod and the first swing disc 304 is rotatably connected to the long rod, when the first swing disc 304 rotates, several convex blocks on its surface will intermittently contact the C-shaped convex blocks on the surface of the rotating disc 303, so that the first swing disc 304 swings back and forth. When the first swing disc 304 swings back and forth, it will cause the second swing disc 308 to swing back and forth through the crank rod 306. When the second swing disc 308 swings back and forth, it will drive the abrasive belt 307 to swing back and forth together, so as to rub the dust and impurities on the surface of the cable, clean the impurities on the outer surface of the cable, reduce the wear caused by the friction of the impurities on the outer surface of the cable, and reduce the damage to the parts caused by the impurities falling into the parts inside the adjusting mechanism 2, thereby reducing the service life of the device and improving the cable pulling efficiency.

[0032] When the crank rod 306 rotates around the long rod, it will drive the second gear 402 to rotate together. Since the first gear 401 is fixedly connected to the long rod and the first gear 401 meshes with a plurality of second gears 402, when the plurality of second gears 402 rotate, they will be blocked by the first gear 401 and thus rotate. When the second gear 402 rotates, it will cause a plurality of push blocks 403 to rotate together. The push blocks 403 are arranged in a staggered manner, one above the other, and a first spring is fixedly connected between two staggered push blocks 403. A spring block 404 is fixedly connected between the first springs. When the push blocks 403 rotate, the spring block 404 will swing back and forth through the first spring, thereby playing a role in knocking and vibrating the abrasive belt 307. Through vibration, the impurities and dust on the surface of the cable will fall off, further improving the protection of the cable, avoiding the situation that impurities generate friction on the surface of the cable as the abrasive belt 307 swings during friction and causing wear on the outer surface of the cable, and further enhancing the cleaning efficiency of the abrasive belt 307 on the surface of the cable.
