- the assembling process of the curved skin block frames of a hull of this invention comprises the steps of positioning devices 11 for positioning of the transverse reinforcing members 8, and then aligning longitudinal reinforcing members 7 in such a manner that devices 12 for tentatively positioning the longitudinal members 7 are attached to a faceplate thereto and faced upwardly.
- the transverse members 8 are inserted into the devices 11 so that the slotted sides of the transverse members 8 face downwardly and so as to position several transverse members 8 in substantially parallel relation to each other by adjusting the inclination of the transverse members 8, and the longitudinal members 7 tentatively positioned beneath the transverse members 8 are lifted one by one so as to insert the longitudinal members 7 into the slots of the transverse members 8 to assemble skin reinforcing assembly 13 (see FlG. 3e) separately from the skin.
- the reinforcing assembly 13 is moved onto the skin 4 assembled by another stool so as to unite it therewith in a unitary construction 9 (see FIG. 31').
- Reference numerals l1 illustrate the devices for positioning the transverse members 8 by supporting the transverse members 8 near both ends thereof to hold them at a certain height above the ground.
- the numerals 12 identify devices attached to a faceplate for tentatively positioning the longitudinal members 7.
- the positions of the members 7 correspond to the positions of the slots of the transverse members 8.
- the device 15 positions the longitudinal members 7, tentatively positioned by the devices 12, so as to lift them one-by-one from underside of the transverse members 8 and to insert them into corresponding slots 10 of the transverse members 8.
- the tentative attachment and welding of the transverse and longitudinal members 8, 7 after positioning of the longitudinal members 7, are conducted by a device (not shown) for tentatively attaching or welding immediately after the longitudinal members are positioned in the manner heretofore described.
- a device for tentatively attaching or welding immediately after the longitudinal members are positioned in the manner heretofore described.
- an operator may ride on a working stool (not shown) that is capable of moving beneath the positioned longitudinal members 7 'so as to first tentatively attach them and to thereafter weld them to the transverse members 8.
- FIGS. 5a and 5b show the main steps of the present invention in the device for positioning the transverse members 8 the device comprises sets of opposing devices 11 for holding each transverse member 8 near the ends thereof.
- Reference numeral 110 illustrates a mechanism for adjusting the position in the transverse direction of each transverse member 8, which is driven on wheels 11b, for example, through a speed reduction or change motor (not shown) along guide rails llc extending in a transverse direction.
- the positioning of the mechanism is conducted by determining in advance the length of each transverse member 8 (the distance between the transverse member supporting points 11d at both ends of each transverse member) and by matching the dimensions thereof to a scale (not shown) parallel with the guide rails.
- Numeral lle shows a mechanism similar to the mechanism 11a, for adjusting the position in the longitudinal direction of each transverse member 8 driven on wheels 11f, for example, by a speed reduction or change motor (not shown) along the guide rails 11g extending in the longitudinal direction.
- the operation of the mechanism lie is also conducted by previously determining the position of each transverse member with respect to the other transverse members so as to adjust them by observing a scale (not shown) provided parallel with the guide rails 11g.
- 11h illustrates a mechanism for adjusting the position in the elevational direction of the transverse member supporting points so as to move elevationally the supporting points by means of, for example, the extension and contraction of a hydraulic ram or rotation of polygonal screw lli.
- llj shows a cylinder for guiding elevationally.
- the elevational height of each transverse member is adjusted by previously determining the height of the transverse member supporting points and by observing a scale (not shown) in the elevational direction.
- 11k illustrates a mechanism for adjusting the oblique angle of each transverse member 8, for example, in such a manner that a handle 11! is turned to rotate a worm wheel llni through a work gear 11m so as to incline the transverse member supporting stool lle integrally connected to the rotary shaft of the worm wheel, lln. The angle is adjusted by observing a scale (not shown) attached thereto.
- 11p shows a transverse member clamping device so as to clamp the transverse member 8 by a hydraulic ram after its positioning.
- the values previously calculated may be used for automatically positioning members by numerical control or a remote control system, with numerical information such as a punch tape or the like, so that the step of adjusting by observing the scale may be omitted so as to accurately and automatically position the members 8.
- FIGS. 60 and 6b show the main steps of the present invention in a device for positioning the longitudinal members 7.
- Reference numeral 15a identifies a carriage for moving the longitudinal members 7 one-by-one from the longitudinal member tentative positioning devices 12 to the slots of the transverse members 8 corresponding thereto.
- the numeral 15b identifies a mechanism for elevationally moving each longitudinal member 7 and is driven elevationally by the rotation of the polygonal screw 15d driven, for example, by a speed reduction or change motor (not shown) along the guide rails 150.
- the numeral [5e identifies a mechanism for inclining each longitudinal member 7 lifted upwardly in the longitudinal direction by means of the extension or contraction of the hydraulic ram 15g connected at both ends thereof by, for example, a pin joint at the center of the brackets 15f.
- the numeral 15h identifies a longitudinal member-holding stool having a longitudinal member clamping device 151' using a hydraulic ram for clamping each longitudinal member 7 and for inclining the longitudinal member-supporting stool integral with the worm wheel by means of the rotation of the worm wheel k through the worm gear 15j driven, for exam ple, by a speed reduction or change motor (not shown) to incline the longitudinal member in the transverse direction.
- a speed reduction or change motor not shown
- the process for inserting the longitudinal members from upper sides of the transverse members requires carrying members such as crane or the like for carrying the longitudinal members, and accordingly the longitudinal members must be positioned one-by-one, with the result that it is impossible to position a plurality of longitudinal members simultaneously, thereby requiring a long operating time.
- the disposition, positioning and welding of the reinforcing members may be mechanized even in assembling the curved skin block of complicated curved structures and to install them so that the reinforcing member of crossbeam structures is inclined.
- effort is greatly saved and productivity thereof is also greatly improved in comparison with the conventional methods.
