Make sure your controller is same which loads the layout in which your block and its child blocks exits.


use Magento\Backend\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;

class Edit extends \Magento\Backend\App\Action
{
  protected $resultPageFactory;

  public function __construct(
       Context $context,
       PageFactory $resultPageFactory
  ){
       $this->resultPageFactory = $resultPageFactory;
       parent::__construct($context);
  }

  $resultPage = $this->resultPageFactory->create();

  $blockInstance = $resultPage->getLayout()->getBlock('your.block.name');

  $childBlocks = $blockInstance->getChildNames();

  foreach($childBlocks as $blockName){
    $block = $resultPage->getLayout()->getBlock($blockName);
  }

}
