Abstract
Abstract A connection device includes two assemblies, movable towards each other. One of the assemblies has a first mechanical connection plate unit and a first connection element fixed to the plate unit. The other assembly includes a second mechanical connection plate unit and a second connection element movable with respect to the second plate unit in a direction parallel to the engagement direction. The second plate unit includes centering pins for engaging the first plate and providing relative centering of the two plates, remote controlled for locking the plate units one on the other and in aligned position of the contacts. Motors are carried by the second plate unit for moving the second connection element with respect to the second plate unit between a rear position in which the contacts of the elements are mutually separated even when the plate units are in contact with each other and a forward position in which the contacts of the two elements are in mutual engagement.

Claim 1
Independent Claim
222 words
A self-alignment multiple connection device having two assemblies, one of which is movable in a direction towards and away from the other, wherein: one of the assemblies has a first mechanical connection plate and a first connection element provided with contacts and fixed to the mechanical connection plate; the other assembly includes a second mechanical connection plate and a second connection element provided with contacts arranged and distributed for operatively engaging the contacts of the first connection element upon movement of the latter along said direction toward the first plate, said second connection element being movable with respect to said second mechanical connection plate, along said direction; and said second mechanical connection plate carries members arranged to engage the first plate and to achieve mutual centering of the two plates upon closing movement thereof along said direction, remotely controlled means for locking the plates one on the other in aligned and mutually abutting condition and drive means for moving said second connection element along said direction with respect to said second plate between a rear position in which the contacts of the first and second elements are separated from each other even when the plates are in abutting condition and a forward position in which the contacts of the two elements are in mutual engagement when the plates are in abutting condition.

A self-alignment multiple connection device having two assemblies, one of which is movable in a direction towards and away from the other, wherein: one of the assemblies has a first mechanical connection plate and a first connection element provided with contacts and fixed to the mechanical connection plate; the other assembly includes a second mechanical connection plate and a second connection element provided with contacts arranged and distributed for operatively engaging the contacts of the first connection element upon movement of the latter along said direction toward the first plate, said second connection element being movable with respect to said second mechanical connection plate, along said direction; and said second mechanical connection plate carries members arranged to engage the first plate and to achieve mutual centering of the two plates upon closing movement thereof along said direction, remotely controlled means for locking the plates one on the other in aligned and mutually abutting condition and drive means for moving said second connection element along said direction with respect to said second plate between a rear position in which the contacts of the first and second elements are separated from each other even when the plates are in abutting condition and a forward position in which the contacts of the two elements are in mutual engagement when the plates are in abutting condition.
Claim 3
Dependent Claim
43 words
The device as claimed in claim 1, wherein said remotely controlled means include movable means for clamping said plates against each other and motor means for retaining the clamping means in a position locking the plates on each other in mutually abutting condition.
Claim 4
Dependent Claim
75 words
The device as claimed in claim 2, wherein said movable clamping means comprises a plurality of units each having a body secured to said second plate and formed with a centering nose and a plurality of fingers pivotably mounted on the body for pivotal movement between a locking position and a position in which their overall size in a plane transversal to said direction is smaller than the cross-section of the body in said plane.
Claim 5
Dependent Claim
25 words
The device as claimed in claim 1, wherein one of said plates further includes curved precentering means, projecting beyond said plate toward the other plate.
Claim 6
Dependent Claim
21 words
The device as claimed in claim 1, wherein said plates include sealing means for separating the connection elements from the outside.
Claim 7
Dependent Claim
29 words
The device as claimed in claim 1, further comprising motor means carried by the second plate for moving said second connection element and holding it in fully engaged position.
Claim 8
Dependent Claim
21 words
The device as claimed in claim 1, wherein said other assembly is carried by a drive arm through a universal joint.
Claim 9
Dependent Claim
69 words
The device as claimed in claim 7, wherein said arm has a power cylinder for moving it between a position for mutual connection of said connection elements and a disconnected position and said arm is mounted on a lifting beam having a power cylinder for moving an assembly formed by the beam, the arm and said other assembly towards a position clearing a space situated above said first assembly.
