In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is more than two.

[0028] In one embodiment of the present utility model, as Figures 1-4As shown in the figure, a coil lifting device includes a lifting member 1, a column 2, a connecting member 3, a moving seat 4, a locking assembly 5, a clamping and limiting assembly 6, and a bottom plate 7. One end of each of the left and right ends of the lifting member 1 is hinged to one end of the connecting member 3, and the other end of the connecting member 3 is connected to the top of the column 2. The connecting member 3 is inclined. The bottom of the column 2 is provided with the bottom plate 7. The moving seat 4 is movably mounted on the column 2 in the up and down direction. The locking assembly 5 is used to lock and fix the moving seat 4. The clamping and limiting assembly 6 is mounted on the moving seat 4, and the clamping and limiting assembly 6 is used to clamp and limit the transformer coil. In this embodiment, the numbers of the column 2, the connecting member 3, the moving seat 4, the locking assembly 5, the clamping and limiting assembly 6, and the bottom plate 7 are all two. One end of the two connecting members 3 is hinged to the left and right ends of the lifting member 1, and the other ends of the two connecting members 3 are connected to the tops of the two columns 2. The connecting member 3 and the column 2 are of an integral structure. The two bottom plates 7 are mounted at the bottom of the column 2. The distance between the two clamping and limiting assemblies 6 can be adjusted adaptively through the hinge of the lifting member 1. During operation, the hook of the overhead crane equipment is hooked to the lifting member 1, and a winding shaft is provided between the two bottom plates 7. According to the length of the transformer coil to be wound in the left and right directions, the position between the two bottom plates 7 is adjusted, so as to adjust the distance between the two clamping and limiting assemblies 6. And according to the height of the transformer coil to be wound, the height position of the moving seat 4 is adjusted, and the moving seat 4 is locked and fixed by the locking assembly 5. When the winding of the transformer coil is completed, at this time, the front and rear sides of the transformer coil are clamped and limited by the two clamping and limiting assemblies 6 at the left and right ends. After the transformer coil is fixed and limited, the overhead crane equipment rises, so as to lift the coil lifting device upward, that is, the two bottom plates 7 lift the transformer coil, so as to take the transformer coil out of the winding column, which is convenient for the subsequent transformer coil sleeving process. Through the lifting member 1, the column 2, the connecting member 3, the moving seat 4, the locking assembly 5, the clamping and limiting assembly 6, and the bottom plate 7 of the present application, after the winding of the transformer coil is completed, the two clamping and limiting assemblies 6 are used to clamp and limit the transformer coil from the front and rear directions and the left and right directions, and cooperate with the bottom plate 7 to lift the transformer coil, ensuring that the transformer coil is lifted in a stable state. Compared with the traditional method of using a sling to tighten both ends of the winding shaft of the winding machine and then removing the fixing devices on both sides of the winding shaft, it can not only avoid the phenomenon of different sling lengths and different force centers when using a sling to fix the transformer coil, but also save the installation time of the transformer winding mold and the hoisting time of the transformer coil, which is beneficial to improving production efficiency.

[0029] As Figures 2-3As shown, the clamping and limiting assembly 6 includes a rotating shaft 61, a gear 62, a clamping member 63 and a driving part; the rotating shaft 61 is rotatably installed on the moving seat 4, one end of the rotating shaft 61 is installed with the gear 62, the other end of the rotating shaft 61 is installed with the clamping member 63, and the driving part is used to drive the gear 62 to rotate. In this embodiment, each group of the clamping and limiting assemblies 6 includes two rotating shafts 61, two gears 62, two clamping members 63 and two driving parts. The driving part is a motor. The rotating shaft 61 is rotatably installed on the moving seat 4. The top of the rotating shaft 61 protrudes from the top surface of the moving seat 4, and the gear 62 is installed on the top of the rotating shaft 61, while the clamping member 63 is installed in the main body area of the rotating shaft 61. The clamping member 63 is located below the gear 62. The two driving parts are respectively installed on the top surface of the moving seat 4. During operation, the two driving parts respectively drive the two gears 62 to rotate. The gear 62 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the clamping member 63 to swing. Specifically, the clamping and limiting ends of the two clamping members 63 move away from each other, so as to ensure that there is enough space for winding the transformer coil. After the winding is completed, the two driving parts respectively drive the two gears 62 to rotate, so that the clamping and limiting ends of the two clamping members 63 approach each other until the two clamping members 63 respectively abut against the outer periphery of the transformer coil, so as to achieve the purpose of clamping and limiting, thus ensuring the stability of subsequent lifting and preventing the transformer coil from swinging or shaking.

[0030] As Figures 2-3 shown, a soft pad 631 is provided on the inner side of the clamping member 63. In this embodiment, a soft pad 631 made of rubber material is provided on the inner side surface of the clamping member 63. Due to its good elasticity, shock absorption, wear resistance, anti-slip property and insulation property, it can not only prevent the clamping member 63 from damaging the transformer coil, but also avoid the phenomenon of slipping between the transformer coil and the clamping member 63, achieving the effect of improving the service life and clamping performance of the clamping member 63.

[0031] As Figures 2-3 shown, the two gears 63 mesh with each other. The driving part is installed on the top surface of the moving seat 4, and the output end of the driving part meshes with one of the gears 63. In this embodiment, the driving part is a motor, and the output end of the driving part meshes with one of the gears 63. And because the gears 63 of the two rotating shafts 61 mesh with each other, that is, the gear meshing with the driving part is the driving gear, and the other gear is the driven gear. Through the above structure, one driving motor can drive the two gears 63 to rotate, and the rotation directions are opposite, so as to achieve the purpose of opening and closing the two clamping members 63, which is beneficial to reducing the production cost of the coil lifting device.

[0032] AsFigures 1-3 As shown in the figure, the locking assembly 5 includes a plug rod 51, a blocking plate 52 and a locking nut 53; the column 2 is provided with a plurality of first through holes 21, and the plurality of first through holes 21 are evenly spaced along the height direction of the column 2. The moving seat 4 is provided with a second through hole 41, and the second through hole 41 can be aligned with the first through hole 42; one end of the plug rod 51 is installed on the blocking plate 52, and the other end of the plug rod 51 passes through the second through hole 41 and the first through hole 21, and the other end of the plug rod 51 protrudes from the rear end face of the column 2. The locking nut 53 is installed on the other end of the plug rod 51. In this embodiment, when the height position of the moving seat 4 needs to be adjusted, specifically, the moving seat 4 is moved up and down along the height direction of the column 2. After moving to a suitable position, the second through hole 41 of the moving seat 4 is aligned with the first through hole 21 of the column 2, and the end of the plug rod 51 is passed through the second through hole 41 and the first through hole 21 from front to back until the blocking plate 52 fits against the column 2. Then, the locking nut 53 is screwed onto the protruding end of the plug rod 51 until the locking nut 53 fits against the column 2. It should be noted that the protruding end of the plug rod 51 is provided with a thread, so that the moving seat 4 is fixed to the column 2, and the disassembly and assembly are convenient, which is beneficial to improving the adjustment efficiency of the moving seat 4.

[0033] As Figures 1-3 shown in the figure, two of the plug rods 51 are installed on the rear end face of the blocking plate 52. In this embodiment, two of the plug rods 51 are installed on the rear end face of the blocking plate 52, and the first through hole 21, the second through hole 41 and the locking nut 53 are correspondingly and adaptively arranged. The moving seat 4 is fixedly installed on the column 2 through the two plug rods 51, which is beneficial to improving the installation stability of the moving seat 2, reducing the bearing strength of the plug rod 51, and is beneficial to improving the service life of the plug rod 51.

[0034] As Figures 2-3 shown in the figure, the column 2 is provided with a guide rail 22, and the moving seat 4 is provided with a sliding groove 42. The moving seat 4 is slidably installed on the guide rail 22 through the sliding groove 42.

The moving seat 4 is slidably installed on the guide rail 22 through the two sliding grooves 42. Through the guide rail 22 structure, it is beneficial to improve the moving smoothness of the moving seat 4 and the accuracy of the moving direction.

[0035] As Figure 4 shown in the figure, sponge pads 71 are respectively provided on the bottom surfaces of the front and rear ends of the bottom plate 7. The sponge pads 71 are respectively provided on the bottom surfaces of the front and rear ends of the bottom plate 7. When the coil lifting device is placed on the ground, the sponge pads 71 play a role of buffering and shock absorption, which is beneficial to improving the placement stability of the coil lifting device.

[0036] As Figure 4 shown, the bottom surface of the bottom plate 7 is provided with anti-slip lines, and the anti-slip lines are located between the two sponge pads 71. In this embodiment, the anti-slip lines are provided on the bottom surface of the bottom plate 7, and the anti-slip lines are arranged between the two sponge pads 71. The anti-slip performance of the bottom plate 7 is improved through the anti-slip lines, so as to prevent the two bottom plates 7 from sliding and shifting after the coil lifting device is placed on the ground.
