A limiting column is rotatably connected in the column hole, and a notch adapted to the inner ring of the hoop seat is provided on the side surface of the limiting column.

[0009] The surface of the limiting column is provided with an annular tooth groove, and the side surface of the moving pin is provided with a tooth surface meshing with the tooth groove.

[0010] The limiting column consists of a column base and two column blocks, and the two column blocks are slidably connected along the column base. The notch is located on the two column blocks, and a spring sheet is arranged between the two column blocks. The spring sheet pushes the two column blocks to move away from each other. Both ends of the column hole are provided with semicircular sockets that cooperate with the column blocks on the same side.

[0011] The transformer body and the base are provided with self-locking components matched with the column blocks.

[0012] Preferably, the self-locking component includes a sliding cavity opened inside the base, and the sliding cavity is connected to the semicircular socket, a sliding pin is slidably connected in the sliding cavity, and an oblique opening matching with the sliding pin is opened at one end of the sliding pin close to the column block, a top spring is arranged inside the sliding cavity, and the top spring pushes the sliding pin to move toward the column block.

[0020] Preferably, the outer surface of the column seat is provided with anti-slip teeth.

[0021] Preferably, a rubber cover is provided inside the unlocking hole.

[0022] A method for using a dry-type transformer that is easy to disassemble and assemble comprises the following steps:

[0023] S1. Install the limit hoop on the electric pole, and then install the base on the electric pole through the hoop seat and the outer hoop on both sides. At this time, the outer hoop and the hoop seat can move up and down along the electric pole. Then connect the hook frame through the lifting equipment, mobilize and move the base upward until the outer hoop and the hoop seat are blocked by the limit hoop. At this time, the hook frame pulls the moving pin to compress the tension spring and move it upward along the base, and pushes the limit column to rotate, so that it changes from the notch alignment of the electric pole to the column seat alignment. At the same time, the column block is automatically inserted and locked after being aligned with the semicircular socket, so that the column seat is used to fill the gap between the hoop seat and the electric pole for fixing;

[0024] S2. When the column block is inserted into the semicircular socket, it simultaneously squeezes the sliding pin along the oblique opening. When the transformer body is hoisted onto the base, the plug on the lower side presses down the spring tongue to unlock the buckle and the sliding pin. At this time, the sliding pin is affected by the column block and the top spring is compressed to move, so that the buckle and the plug are plugged together, thereby locking and installing the transformer on the base.

[0025] S3. When disassembling the transformer body, use a tool to insert it along the unlocking hole, and after passing through the through slot, initially press the column block to unlock the sliding pin. At this time, the top spring pushes the buckle to unlock the plug, and the transformer body can be lifted out. Further press the column block to disengage from the semicircular socket to unlock the column seat. The movable pin can move downward to push the limit column to rotate, so as to loosen the fixation of the hoop seat and the outer hoop along the electric pole. At the same time, the movable sliding pin uses the connecting rod to push the clamping ring to release the blockade of the outer hoop head, so that the outer hoop can be disassembled after the base falls to the ground.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the present invention, the movable pin is pulled by the hook frame to compress the tension spring and move upward along the base, and the limiting column is pushed to rotate, so that it changes from the notch alignment with the electric pole to the column seat alignment, and at the same time, the column block is automatically inserted and locked after being aligned with the semicircular socket, so that the column seat is used to fill the gap between the hoop seat and the electric pole for fixation. Compared with the existing high-altitude operation to complete the fixation of the transformer seat, the hoop seat and the outer hoop can complete the non-rigid connection between the base and the electric pole on the ground, and after lifting, the limiting hoop is used to supplement the rigid connection, so that the overall fixing operation does not require manual climbing at a high place, has better operational safety, and the fixing step does not require too much manual assistance, thereby improving the convenience of installation.

[0028] In the present invention, the plug presses down the spring tongue to unlock the buckle and the sliding pin. At this time, the sliding pin is acted upon by the column block, and the compression top spring is displaced to plug the buckle and the plug, thereby locking and installing the transformer on the base. Compared with the existing manual motor locking, the sliding pin can be preset by the column block, and the locking process is started in conjunction with the placement of the transformer body, without the need for workers to perform additional installation operations, thereby greatly improving the installation efficiency of the overall equipment.

[0029] In the present invention, the column block is initially pressed to unlock the sliding pin, and the transformer body is lifted out. The column block is further pressed to disengage from the semicircular socket to unlock the column seat, and the movable pin can move downward to push the limit column to rotate, so as to loosen the fixation of the hoop seat and the outer hoop along the electric pole. At the same time, the movable sliding pin uses the connecting rod to push the clamping ring to release the blockade of the outer hoop head, so that the outer hoop can be disassembled after the base falls to the ground. Compared with the independent connection between the existing transformer seat and the electric pole and the transformer, the above-mentioned sliding pin can keep the operation restriction on the outer hoop in a chain when the transformer body is not unlocked, so that the operator can only disassemble the transformer body and the base step by step according to the operation specifications, but cannot illegally unlock the outer hoop and lift the base and the transformer body together. In this way, the actual operation is constrained by the equipment operation logic, thereby improving the operation safety. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting column 57 is rotatably connected inside the column hole 56, and a notch 58 adapted to the inner circle of the hoop seat 3 is provided on the side surface of the limiting column 57. The hook frame 52 is connected through the lifting equipment to mobilize the base 2 to move upward until the outer hoop 4 and the hoop seat 3 are blocked by the limiting hoop 51. At this time, the hook frame 52 pulls the moving pin 53 to compress the tension spring 55 and move upward along the base 2.

[0044] An annular tooth groove 59 is formed on the surface of the limiting column 57 , and a tooth surface 510 meshing with the tooth groove 59 is formed on the side surface of the moving pin 53 .

[0045] The limiting column 57 is composed of a column base 571 and two column blocks 572, and the two column blocks 572 are slidably connected along the column base 571. The notch 58 is located on the two column blocks 572, and a spring sheet 511 is arranged between the two column blocks 572. The spring sheet 511 pushes the two column blocks 572 to move away from each other. Both ends of the column hole 56 are provided with semicircular sockets 512 that cooperate with the column blocks 572 on the same side. When the movable pin 53 moves upward, it pushes the limiting column 57 to rotate, so that it changes from the notch 58 to the electric pole to the column base 571. At the same time, the column block 572 is automatically inserted and locked after being aligned with the semicircular socket 512, so that the column base 571 is used to fill the gap between the hoop seat 3 and the electric pole for fixing.

[0046] The transformer body 1 and the base 2 are provided with a self-locking assembly 513 that matches with the column block 572 .

[0049] A spring tongue 5138 is provided on the top of the base 2 to block the plug 5136. After the transformer body 1 is lifted onto the base 2, the plug 5137 on the lower side presses down the spring tongue 5138 to unlock the plug 5136 and the sliding pin 5132. At this time, the sliding pin 5132 is acted upon by the column block 572, and the compression top spring 5134 is displaced to connect the plug 5136 with the plug 5137.

[0050] The base 2 and the sliding pin 5132 are provided with a safety assembly 5139 which cooperates with the hoop seat 3 and the outer hoop 4 .

[0057] A method for using a dry-type transformer that is easy to disassemble and assemble comprises the following steps:

[0058] S1. Install the limiting hoop 51 on the electric pole, and then install the base 2 on the electric pole through the hoop seat 3 and the outer hoop 4 on both sides. At this time, the outer hoop 4 and the hoop seat 3 can move up and down along the electric pole. Then connect the hook frame 52 through the lifting equipment to mobilize the base 2 to move up until the outer hoop 4 and the hoop seat 3 are blocked by the limiting hoop 51. At this time, the hook frame 52 pulls the moving pin 53 to compress the tension spring 55 to move up along the base 2, and pushes the limiting column 57 to rotate, so that it changes from the notch 58 to the electric pole to the column seat 571. At the same time, the column block 572 is automatically inserted and locked after being aligned with the semicircular socket 512, so that the column seat 571 is used to fill the gap between the hoop seat 3 and the electric pole for fixing.

[0059] S2. When the column block 572 is inserted into the semicircular socket 512, it simultaneously squeezes the sliding pin 5132 along the bevel 5133. When the transformer body 1 is hoisted onto the base 2, the plug 5137 on the lower side presses down the spring tongue 5138 to unlock the buckle 5136 and the sliding pin 5132. At this time, the sliding pin 5132 is affected by the column block 572, and the compression top spring 5134 is displaced to connect the buckle 5136 with the plug 5137, so as to lock and install the transformer on the base 2.

When disassembling the transformer body 1, use a tool to insert it along the unlocking hole 51393, pass through the through groove 51394, and initially press the column block 572 to unlock the sliding pin 5132. At this time, the top spring 5134 pushes the buckle 5136 to unlock the plug 5137, and the transformer body 1 can be lifted out. Further press the column block 572 to disengage from the semicircular socket 512 to unlock the column seat 571. The movable pin 53 can move downward to push the limiting column 57 to rotate, so as to loosen the fixation of the hoop seat 3 and the outer hoop 4 along the electric pole. At the same time, the moving sliding pin 5132 uses the connecting rod 51391 to push the clamping ring 51392 to release the blockade of the hoop head of the outer hoop 4, so that the outer hoop 4 can be disassembled after the base 2 falls to the ground.

At this time, the hook frame (52) pulls the moving pin (53) to compress the tension spring (55) and move up along the base (2), and pushes the limit column (57) to rotate, so that it is transferred from the notch (58) to the column seat (571) to the electric pole. At the same time, the column block (572) and the semicircular socket (512) are automatically inserted and locked after being aligned, so that the column seat (571) is used to fill the gap between the hoop seat (3) and the electric pole for fixing; S2. When the column block (572) is inserted into the semicircular socket (512), the sliding pin (5132) is squeezed along the oblique opening (5133) simultaneously. When the transformer body (1) is hoisted onto the base (2), the plug (5137) on the lower side presses down the spring tongue (5138) to unlock the plug buckle (5136) and the sliding pin (5132). At this time, the sliding pin (5132) is acted upon by the column block (572) and the compression top spring (5134) is displaced, so that the plug buckle (5136) and the plug (5137) are plugged together, thereby locking and installing the transformer on the base (2); S3. When removing the transformer body (1), a tool is inserted along the unlocking hole (51393), passed through the through slot (51394), and then initially pressed against the column block (572) to unlock the sliding pin (5132). At this time, the top spring (5134) pushes the buckle (5136) to unlock the plug (5137), and the transformer body (1) can be lifted out. The column block (572) is further pressed to disengage from the semicircular plug hole (512) to unlock the column seat (571). The movable pin (53) can move downward to push the limit column (57) to rotate, so as to loosen the fixing of the hoop seat (3) and the outer hoop (4) along the electric pole. At the same time, the movable sliding pin (5132) uses the connecting rod (51391) to push the clamping ring (51392) to release the blockade of the hoop head of the outer hoop (4), so that the outer hoop (4) can be removed after the base (2) falls to the ground.
