How to restore bitcoin wallet if key not in WIF format?
May be exist wallets for this task?

If it isn't in WIF format... most wallets are NOT going to be able to import it...

You can try entering your "private key" into https://www.bitaddress.org/ (NOTE: download, run "offline"... click on "Wallet Details" tab). It purports to accept - WIF (starts with "5"), WIFC (WIF Compressed, starts with "K" or "L"), HEX, B64 (Base64), B6 (Base6... ie. "dice"), MINI, BIP38 (BIP38 Encrypted)

It will display the WIF and WIF Compressed keys along with the matching bitcoin addresses, so you know which WIF key to use to import into the wallet of your choice.

Things will be slightly more complicated if your private key is in "xprv" format.
