Abstract

Η εφεύρεση αφορά ένα κύλινδρο μανδάλωσης (20), ο οποίος περιλαμβάνει τον κύλινδρο (21) και το έμβολο (22), το οποίο μπορεί να κινείται κατά μήκος του κυλίνδρου (21) με τη βοήθεια ενός μέσου πίεσης. Το έμβολο (22) εμπλέκεται μέσω του μη αυτοσυγκρατούμενου, λόγω τριβής, σπειρώματος(37) με την άτρακτο (35). Η τελευταία έχει τουλάχιστον μία εσοχή μανδάλωσης (38) , στην οποία μπορεί (-ούν) να εμπλέκεται (-ονται) ένας ή περισσότεροι πείροι (40), ο (οι) οποίος (-οι) πείρος (-οι) ωθείται (-ούνται) από τη δύναμη ελατηρίου (-ων). Κατ'αυτόν τον τρόπο, ο (οι) πείρος (-οι) μπορεί (-ουν) να οδηγείται (-ούνται) σε μία θέση μανδάλωσης, στην οποία ο (οι) πείρος (-οι) εμπλέκεται (-ονται) μέσα στην (στις) εσοχή (-ες) μανδάλωσης (38) της ατράκτου (35). Το μέσο πίεσης μπορεί να προσάγεται σε αμφότερες τις πλευρές (44,46) του εμβόλου και πέραν τούτου μπορεί να προσάγεται στον (στους) πείρο(-ους) μανδάλωσης (40). Οι πείροι μανδάλωσης (40) μπορούν να κινούνται ξεχωριστά μεταξύ τους. Ακόμη, η άτρακτος (35) μπορεί να κινείται στην αξονική διεύθυνση και να εδράζεται μέσω ελατηρίων. Εξάλλου, είναι δυνατόν να εφαρμοσθούν τα μέσα (150) για τη συγκράτηση του φορτίου και για πέδηση ενάντια σε πτώση. Με τη βοήθεια των μέσων (150) μπορεί να αποφεύγεται η ανεξέλεγκτη προπορεία του εμβόλου (22). Επίσης, τα μέσα (150) μπορούν να πραγματοποιούν την υδραυλική ασφάλιση του εμβόλου (22) σε μία επιθυμητή θέση συγκράτησης στην διαδρομή αυτού.The invention relates to a locking cylinder (20), which includes the cylinder (21) and the piston (22), which can move along the cylinder (21) with the help of a pressure means. Piston (22) engages via non-self-locking friction thread (37) with spindle (35). The latter has at least one latching recess (38) in which one or more pins (40) may be engaged, which pin(s) are pushed ) by the spring force(s). In this way, the pin(s) can be driven into a latching position, in which the pin(s) engages within the in) the locking recess(es) (38) of the spindle (35). The pressure medium may be supplied to both sides (44,46) of the piston and may additionally be supplied to the locking pin(s) (40). The locking pins (40) can be moved separately from each other. Furthermore, the spindle (35) can move in the axial direction and be supported by means of springs. Furthermore, it is possible to apply the means (150) for holding the load and for braking against falling. With the help of the means (150) the uncontrolled advance of the piston (22) can be avoided. Also, the means (150) can carry out the hydraulic locking of the piston (22) in a desired holding position in its path.
