This will give you the ids of the rules applied to the quote separated by comma.

    public function __construct(
                                \Magento\Checkout\Model\Session $checkoutSession,
                                \Magento\SalesRule\Api\RuleRepositoryInterface $ruleRepositoryInterface,
                               ) {
                                 $this->checkoutSession = $checkoutSession;
                                 $this->ruleRepositoryInterface = $ruleRepositoryInterface;

    $appliedRuleIds = $this->checkoutSession->getQuote()->getAppliedRuleIds();

if you want to get the rules applied as objects you can do this:

$appliedRuleIds = explode(',', $appliedRuleIds);

foreach ($appliedRuleIds as $appliedRuleId) {
