DETAILED DESCRIPTION

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: Refer to the attached Figure 1-4The present embodiment provides a horizontal storage rack for transformer coils, comprising two sets of storage devices symmetrically arranged, wherein the storage device comprises a support base 1, a bracket 2, a placement groove 3, a rotating bearing 4, a pulley 6, a spring 7 and a base 8. The support base 1 is provided with a bracket 2, and an arc-shaped placement groove 3 is provided on the top of the bracket 2. Two rotating bearings 4 are symmetrically provided at both ends of the placement groove 3. The two ends of the load-bearing shaft 1202 of the adjustable mold 12 with a horizontal coil are respectively placed on the two rotating bearings 4 of the corresponding storage device, and the points of the two rotating bearings 4 are located on the same circumference, and the center of the circumference coincides with the center of the placement groove 3; spring brackets 10 are provided on both sides of the support base 1, and the pulley 6 is rotatably arranged at the bottom of the pulley rod 9. The upper part of the pulley rod 9 is penetrated and arranged on the spring bracket 10 and is provided with a spring 7.

[0012] The support base 1 is a rectangular frame structure, and spring brackets 10 are arranged at the four corners of the rectangular frame structure. The spring bracket 10 is a U-shaped plate that opens outward. A reinforcing rib 11 is welded between the inner side plate of the spring bracket 10 and the long crossbeam of the support base 1. The upper part of the pulley rod 9 passes through the upper and lower plates of the spring bracket 10 and is locked by a nut. A spring 7 is sleeved on the pulley rod 9 between the upper and lower plates. The spring bracket 10 can move up and down along the pulley rod 9. A limit plate 13 is arranged on the pulley rod 9 between the spring bracket 10 and the pulley 6. When a horizontal coil is placed on the storage device, the spring 7 above the pulley 6 is compressed to make the support base 1 contact the ground.

[0013] The upper end of the rotating bearing 4 is slightly higher than the groove wall of the placement groove 3, which is convenient for the adjustable mold 12 to rotate and adjust the position of the horizontal coil.

[0014] The bracket 2 includes two oblique supports 201 and a crossbeam 202. The bottoms of the two oblique supports 201 are respectively fixed on the two short crossbeams of the support base 1. The tops of the two oblique supports 201 are fixed to the bottom of the placement slot 3. A crossbeam 202 is arranged between the two oblique supports 201. The crossbeam 202 is provided with a plurality of positioning holes 5 which are at the same distance from the center of the placement slot 3 and are distributed in a ring shape. By inserting positioning pins into the positioning holes 5, the crossbeam 202 of the bracket 2 is connected to the fixed plates 1201 on both sides of the adjustable mold 12 with the horizontal coil to prevent the adjustable mold 12 with the horizontal coil from rotating.

[0015] The diameter of the positioning pin should match the connecting hole 1203 on the fixed plate 1201 of the adjustable mold 12.

[0016] Preferably, to prevent the support base 1 from damaging the ground, a 10 mm thick rubber is bonded and fixed below it. After the adjustable mold 12 with the horizontal coil is lifted off the storage rack, the spring 7 stretches to make the support base 1 leave the ground at a certain height to facilitate the movement of the storage rack.

[0017] A method for storing transformer coils horizontally, wherein the adjustable die with horizontal coils on a horizontal winding machine is disassembled, two sets of storage racks are placed side by side, and the two ends of the load-bearing shaft 1202 of the adjustable die 12 with horizontal coils are respectively placed in the placement slots 3 of the corresponding storage racks, and the fixed disks 1201 on both sides of the adjustable die 12 are respectively adjacent to the crossbeams 202 of the corresponding storage racks. After the load is applied, the bracket 2 sinks, so that the support base 1 is close to the ground, and the storage rack cannot move at this time. The adjustable die 12 with horizontal coils can be rotated on the bracket 2 through the rotating bearing 4 on the placement slot 3 to adjust the position of the horizontal coil. After the position of the horizontal coil is adjusted, the positioning pin is inserted into the positioning hole 5, and the crossbeam 202 of the bracket 2 is connected with the fixed disks 1201 on both sides of the adjustable die 12 with horizontal coils to complete the end closing of the horizontal coils. The storage device can be moved by hand when unloaded, which is convenient to use.
