Description

Technical Field

[0001] This utility model relates to the field of transformer coil technology, specifically to a coil fixing structure for a transformer coil pay-off frame. Background Technology

[0002] A transformer consists of an iron core and coils. The coils have two or more windings. The winding connected to the power source is called the primary coil, and the remaining windings are called secondary coils. There is no electrical connection between the coils. The coils are wound with insulated copper wire. Their main functions include voltage transformation, current transformation, and impedance transformation.

[0003] In actual production, cable reeling frames are used to wind and transport cables. Existing cable reeling frames require workers to align the center hole of the reel with the shaft of the reel when installing it. Then, using the threaded engagement between the nut and the thread on the shaft of the reel, the nut is tightened towards the reel to secure it and rotate it. To remove the reel, the nut is removed and the reel is taken off the shaft of the reel. This results in long reel replacement times and requires multiple people to work together to complete the replacement, leading to low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a coil fixing structure for a transformer coil pay-off frame, so as to solve the problems of low coil replacement efficiency and high manpower consumption in the above-mentioned background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coil fixing structure for a transformer coil pay-off frame, comprising a slide rail base, a support frame at the top of the slide rail base, drive components symmetrically arranged on both sides of the middle of the support frame, a friction disc fixedly arranged at the output end of each drive component, a coil arranged on the side of the friction disc away from the drive component, a tensioning component arranged on one side of the center of the coil, a mounting frame arranged between the support frame and the tensioning component, a rotating component arranged between the mounting frame and the tensioning component for rotating the tensioning component at a certain angle, the rotating component being rotatably connected to the mounting frame, and fixedly connected to the tensioning component, and conveying components for driving the coil to rise and fall are also respectively arranged below the coil on one side of the support frame.

[0006] Preferably, the drive assembly includes a first motor, the output end of the first motor is provided with a reducer, the output shaft of the reducer is fixedly connected to the friction disc by bolts, and the end of the output shaft of the reducer passes through the friction disc and is provided with a first cone.

[0007] Preferably, sandpaper is adhered to the side surface of the friction disc.

[0008] Preferably, the mounting bracket and the support bracket are fixedly connected by bolts.

[0009] Preferably, the tensioning assembly includes a second cone located at the center of the side of the spool away from the friction disc. The diameter of the cone's apex is larger than the diameter of the central hole of the spool. A connecting arm is rotatably connected to the side of the second cone away from the spool. A first cylinder is fixedly connected to the end of the connecting arm away from the cone. The output shaft of the first cylinder passes through the rotating assembly and is slidably connected to the rotating assembly. The cylinder body of the first cylinder is fixedly connected to the rotating assembly by bolts.

[0010] Preferably, the rotating assembly includes a mounting platform rotatably connected to the inside of the mounting frame, a connecting rod welded to one side of the mounting platform, and a second cylinder hinged to the end of the connecting rod away from the mounting platform, the cylinder end of the second cylinder being hinged to the support frame.

[0011] Preferably, each of the conveying components includes a base, a screw jack is fixedly mounted on the top of the base, a second motor is driven to one side of the screw jack, and a support plate is fixedly mounted on the top of the screw jack.

[0012] Preferably, the support plate has symmetrically arranged arc-shaped plates on both sides, and the line of symmetry of the support plate and the axis of the friction disk are located in the same vertical plane.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up a conveying component and a slide rail base, the wire reel can be placed on the support plate of the conveying component and raised to the same height as the friction plate by the screw jack. The slide rail base drives the support frame and the main structure of the wire feeding frame to move closer to the wire reel. With the cooperation of the tensioning component and the rotating component, when the wire reel is close to the friction plate, the rotating component is activated to make the connecting arm avoid the wire reel installation route. After the wire reel contacts the friction plate, the rotating component is used to move the second cone to the center hole of the wire reel. At this time, the first cylinder of the tensioning component is activated to make the second cone move closer to the wire reel and contact it, and finally clamp the wire reel. Finally, the driving component drives the friction plate to rotate. The friction plate drives the wire reel to rotate through the friction between the friction plate and the wire reel, thereby realizing the wire feeding and winding operation. The whole process can realize the wire reel fixation without the need for workers to carry and tighten and loosen the nuts to fix the wire reel. This reduces the wire reel replacement time, improves the efficiency of reel replacement, and reduces the labor intensity of workers. Attached Figure Description

[0021] Please see Figure 1-2This utility model provides an embodiment of a coil fixing structure for a transformer coil pay-off frame, comprising a slide rail base 1, a support frame 2 on the top of the slide rail base 1, and drive components 3 symmetrically arranged on both sides of the middle of the support frame 2. Each drive component 3 has a friction disc 4 fixedly mounted at its output end. Sandpaper is adhered to the side surface of the friction disc 4. A coil 5 is mounted on the side of the friction disc 4 away from the drive component 3. The drive component 3 includes a first motor 31, and a reducer 32 is mounted at the output end of the first motor 31. The output shaft of the reducer 32 is fixedly connected to the friction disc 4 by bolts. A first cone 33 is mounted at the end of the output shaft of the reducer 32 passing through the friction disc 4. The first motor 31 drives the friction disc 4 to rotate. After the friction disc 4 contacts the side wall of the coil 5, the friction force drives the coil 5 to rotate. The first cone 33 facilitates the assembly of the coil 5, allowing it to be installed in place and contact the friction disc 4 more quickly.

[0022] A tensioning component 6 is provided on one side of the center position of the coil 5. A mounting frame 7 is provided between the support frame 2 and the tensioning component 6. The mounting frame 7 is fixedly connected to the support frame 2 by bolts. A rotating component 8 is provided between the mounting frame 7 and the tensioning component 6 to make the tensioning component 6 rotate at a certain angle. The rotating component 8 is rotatably connected to the mounting frame 7 and fixedly connected to the tensioning component 6. The tensioning component 8 clamps and loosens the coil 5. When clamping, the friction between the friction plate 4 and the coil 5 makes the coil 5 and the friction plate 4 rotate synchronously.

[0023] Furthermore, in order to achieve clamping, fixing, loosening, and disassembling of the wire spool, the loosening and loosening assembly 6 includes a second cone 61 located at the center of the side of the wire spool 5 away from the friction disc 4. The diameter of the cone base of the second cone 61 is larger than the diameter of the central hole of the wire spool 5. A connecting arm 62 is rotatably connected to the side of the second cone 61 away from the wire spool 5. A first cylinder 63 is fixedly connected to the end of the connecting arm 62 away from the second cone 61. The output shaft of the first cylinder 63 passes through the rotating assembly 8 and is slidably connected to the rotating assembly 8. The cylinder body of the first cylinder 63 is fixedly connected to the rotating assembly 8 by bolts. The output shaft of the first cylinder 63 passes through the rotating assembly 8 to move the connecting arm 62 horizontally, thereby driving the second cone 61 to move closer to and away from the wire spool 5, thereby achieving clamping and loosening of the wire spool 5.

[0024] Furthermore, in order to ensure that the connecting arm 62 and the second cone 61 do not obstruct the spool 5 during installation, a rotating assembly 8 is provided. The rotating assembly 8 includes a mounting platform 81 rotatably connected to the inside of the mounting frame 7. A connecting rod 82 is welded to one side of the mounting platform 81, and a second cylinder 83 is hinged to the end of the connecting rod 82 away from the mounting platform 81. The cylinder end of the second cylinder 83 is hinged to the support frame 2. The second cylinder 83 pushes the connecting rod 82, causing the mounting platform 81 to rotate relative to the mounting frame 7, thereby driving the first cylinder 63 to rotate synchronously. This allows the connecting arm 62 to be removed from the installation path of the spool 5, thus not obstructing the installation and disassembly of the spool 5.

[0025] Below the wire reel 5 on one side of the support frame 2, there are also conveying components 9 for driving the wire reel 5 to rise and fall. Each conveying component 9 includes a base 91, and a screw jack 92 is fixedly installed on the top of the base 91. A second motor 93 is driven to one side of the screw jack 92. A support plate 94 is fixedly installed on the top of the screw jack 92. When the wire reel 5 is placed on the support plate 94, the screw jack 92 drives the wire reel 5 to rise, which can reach a height position similar to that of the friction disc 4. Arc-shaped plates 95 are symmetrically arranged on both sides of the support plate 94, which can better cover the wire reel 5 and have better support performance. The symmetry line of the support plate 94 and the axis of the friction disc 4 are located in the same vertical plane.

[0026] In this embodiment, the empty spool 5 is first placed on the support plate 94. The screw jack 92 is used to raise the height of the spool 5 to a suitable position. The slide rail base 1 is used to bring the support frame 2 closer to the spool. After the spool 5 contacts the friction disc 4, the rotating component 8 is used to rotate the tensioning component 6 by a certain angle so that the second cone 61 can be aligned with the circular hole in the center of the spool 5. Then, the first cylinder 63 of the tensioning component 6 is contracted so that the second cone 61 contacts the spool 5 and generates a clamping force on the spool 5. Finally, the driving component 3 is used to drive the friction disc 4 to rotate. The friction disc 4 drives the new spool 5 to rotate through the friction between it and the spool 5, thereby realizing the winding and unwinding function.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
