var ref = firebase.database().ref().child("datos").child("pedidos").child("nuevos");

How I can do that?

use orderByChild method on the timestamp child (or what ever you use store the time ), and startAt to get the data only that before 24 hours

let before24Hour = new Date().getTime() - (24 * 3600 * 1000);
firebase.database().ref().child('datos/pedidos/nuevos').orderByChild('time').startAt(before24Hour).on('value' , function(snap){
    console.log(snap.val());
});
