The present invention relates to a hull block conveying apparatus for conveying the hull block of the hull manufacturing target of the hull in a launch ship having a height higher than the production hull in carrying out the ship construction in the hull block assembly type.

As shown in FIG. 1, when the hull block (B) manufactured by the manufacturing ship (A) is transferred to the launching ship (C) lower than the production ship (A), the hull using the horizontal bogie or the ship's rail is not required. Although the block can be easily transported to the launching line, if the entrance surface of the launching vessel (C-1) is higher than that of the launching vessel exit (A-1) due to the geographical conditions and various conditions, the manufacturing launching vessel (A) is unavoidable. ) And a launching device installed between the launching vessel (C) and the hull block (B) produced by the manufacturing vessel (A) should be raised to the inlet surface (C-1) of the launching vessel (C).

In particular, the launching of ships requires the high entrance surface (C-1) of the launching ship (C) to be able to slide the ship toward the coast.

As another reason, when the conventional manufacturing fleet and the launching fleet are connected with the same rail and the rear end of the manufacturing fleet is inclined high, the hull block that needs to be manufactured on the flat should be worked on the inclined high manufacturing fleet. It is difficult to back up, and the height of the rear section (A-2) of the manufacturing fleet is considerably higher, so the installation of the manufacturing fleet itself is magnificent and the construction cost is high. By transporting, the work can be saved with ease, precision and facilities.

Hereinafter, the subject matter of the present invention will be described with reference to the drawings.

The present invention, as shown in Fig. 3, installs the manufacturing ship (A) on a flat surface, puts the hull block (B) and installs a short and inclined launch ship (C) on the coast side, but it is possible to assemble the ship on the ship (C) After maintaining a distance, it is possible to pull the conveyer (1) from the launching platform (C) to lift the hull block (B) largely assembled from the manufacturing fleet (A) to the launching platform (C). If the structure is described in detail, the inclined pit (2) is constructed between the manufacturing ship (A) and the launching ship (C), and cylindrical rollers (3) (3 ') are installed on both sides thereof. On top of the rollers 3, 3 'is placed a flat upper limb 5 with rails 4 and 4' mounted on top and a feeder 1 assembled as an arcuate lower support 5 '.

A roller wheel 6, 6 'is installed at the bottom of the feeder 1 so that the roller wheels 6, 6' roll the ground of the pit 2, and the lower support of the feeder 1 5) roll on the top of the roller (3) (3 '). It is the end of the pit (2), and immediately below the inlet surface (c-1) of the launching platform (c), the chain lock (7) (7) in line with the roller wheel (6) (6 ') of the transport (1). '), The chain roller (8) (8') and the connection chain roller (9) (9 ') is fixed to the ground. On the rails 10 and 10 'of the launching line c, a pneumatic gripper 12 having a chain guide 11 and 11' is placed on the front side, and the pneumatic gripper 12 has a chain lock (12). 13) (13 '), and the hydraulic gripper 12a, which is also mounted on the rails 10, 10', behind the pneumatic gripper 12, is connected by a hydraulic jacking cylinder 14, and one chain on each rail Lock (13) -chain guide (11) -chain roller (8) -chainlock (7) -roller wheel (6) -connector roller (9) -connector chain roller (9 ')-roller wheel (6 ') -Chain lock (7')-chain roller (8 ')-chain guide (11')-connected chain or chain (15) over the other chain lock 13 ' .

Reference numeral 16 denotes the storage state of the surplus chain, 17 is the ground fixing mark, 18 is the gripper opening, 19 is the groove where the gripper grips or opens the rails 10, 10 ', 20 is the balance cylinder to be.

The operating state of the present invention as described above is hydraulic and pneumatic hydraulic gripper 12 or pneumatic gripper 12 and hydraulic jacking cylinder 14, chain lock (7) (7 ') (13) (13') Pipes of the opening and closing procedure and timing, etc.), and the hull block (B) on the manufacturing fleet (A) is placed on the conveying table (1) using a general horizontal bogie. Raise the table 1 inclined in the pit 2 so that the rails 4 and 4 'of the conveying table 1 and the rails 10 and 10' of the inlet surface C-1 of the launch line C can be used. In order to transfer the ancestor block (B) to the launching crew (C) in accordance with the above, first unlock the chain locks (7) and (7 '), lock the chain locks (13) and (13'), and the pneumatic gripper (12). Is a free state by opening the rails 10 and 10 ', and the hydraulic gripper 12a operates the hydraulic jacking cylinder 14 in a fixed state in which the rails 10 and 10' are gripped to hold the piston of the jacking cylinder. The pneumatic gripper 12 is fixed Since the chain locks 13 and 13 'of the pneumatic gripper 12 pull the chain 15 as they move along the rails 10 and 10' toward the fur 12a, the chain rollers 8 and 8 ' By way of), the chain 15 rotates the roller wheels 6 and 6 'so that the carriage 1 is moved upwardly and inclined at a predetermined interval along the rollers 3 and 3' surface. A pair of roller wheels (6) and (6 ') are interconnected as connecting rollers (9) and (9'), and the balance cylinder (20) corrects the operating error of the left and right hydraulic jacking cylinders (14). This function contributes to precision.

On the contrary, pneumatic gripper 12 is operated by pneumatic and gripped and fixed on rails 10 and 10 '. Hydraulic gripper 12a is opened by rails 10 and 10' and then hydraulic jacking cylinder. When the 14 is operated, the hydraulic gripper 12a moves forwards at a predetermined interval while the compressed piston is pulled out.

Then, the rails 4 and 4 'of the carriage 1 in a jacking operation in which the carriage 15 is inclined upward again by pulling the chain 15 as the pneumatic gripper 12 in the same order as the first time. ) Is aligned with the rail inlet surface (C-1) of the jacking launching vessel (C) as shown in Fig. 7, and then the chain lock (7) (7 ') is locked to secure the feed table (1) and the rail ( 10) Remove the hydraulic gripper 12a, the hydraulic jacking cylinder 14, and the pneumatic gripper 12 above (10 ') and gently push the hull block (B) on the conveying platform (1) to launch the launching vessel (C). It is to be transferred to the rails 10 and 10 '.

Therefore, the present invention allows the hull block (B) to be easily and efficiently manufactured precisely on a flat surface, and the manufactured hull block (B) is transported to the transport table (1) to be placed on the launching platform (C) simply and quickly. Since the launching vessel (C) does not need to be inclined high behind without any need, the installation cost can be reduced, and the shipbuilding line can be installed even in bad terrain.
