Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding support cradles, and specifically to a spliced cradle structure. Background Art

[0002] In order to improve shipbuilding efficiency, shorten the shipyard production cycle and reduce costs, shipyards generally adopt the off-site parallel construction process for shipbuilding. However, due to the large mass of the superstructure section and the thin bulkhead, the working conditions during barge transportation are more complex and severe than those during land transportation, and the lower bulkhead of the section is prone to deformation. Therefore, traditionally, a cradle needs to be added between the barge deck and the section to protect the lower opening of the section bulkhead.

[0003] However, the existing cradles, in order to fit the bulkhead more closely, are all directly welded into an integral cradle, which is customized for the corresponding section and dedicated to a specific ship, greatly affecting the scope of application of the integral cradle. Moreover, the manufacturing length of the integral cradle is relatively long due to the need to adapt to the shape of the hull, which not only consumes a large amount of materials but also affects the transportation and storage of the cradle. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a spliced cradle structure, which solves the problems mentioned in the above background.

A plurality of vertical support rods are evenly welded on the top of the channel steel. The top of the channel steel is respectively sleeved with the bottoms of the first support pipe and the second support pipe through the vertical support rods. Diagonal support rods are arranged on the front and back of the first support pipe. Joint plates are welded at both ends of the diagonal support rods. The top of the diagonal support rod is welded to the surface of the first support pipe through the joint plate. Positioning plates are welded on the front and back of the first support pipe near the bottom end. A round support rod is welded between the positioning plate and the joint plate at the bottom end of the diagonal support rod. Adjusting rods are slidably connected to the inner walls of the first support pipe and the second support pipe. A support seat is welded to the top of the adjusting rod.

[0009] Preferably, a positioning block is welded on the surface of the joint plate at the bottom end of the inclined strut, and the size of the positioning block is adapted to the size of the inner wall of the groove on the side surface of the channel steel.

[0010] Preferably, a plurality of fixing holes are formed on the surface of the adjusting rod, and the distance between adjacent fixing holes corresponds to the distance between the mounting holes on the surfaces of the first support pipe and the second support pipe.

[0011] Preferably, the movable frame includes an angle frame. Transfer holes and adjusting shaft holes are respectively formed on the surface of the angle frame. The inner wall of the adjusting shaft hole is an oval through groove. A backing plate is welded on the top of the angle frame.

[0014] Preferably, adjacent first support pipes and second support pipes form a group of support members, and the height of each group of support members near the center of the jig gradually decreases.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. For the spliced jig structure, by arranging the first support pipe and the second support pipe, and using bolts to position the heights of the adjusting rod, the first support rod and the second support rod, the jig can be adjusted and supported correspondingly for hulls of different models, thereby increasing the applicable range of the jig.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please refer to Figure 1-11 a spliced jig structure, including: channel steel 1, a first support pipe 3 and a second support pipe 4. Multiple groups of vertical support rods 2 are evenly welded on the top of the channel steel 1. The top of the channel steel 1 is sleeved with the bottoms of the first support pipe 3 and the second support pipe 4 respectively through the vertical support rods 2. Diagonal support rods 12 are arranged on the front and back of the first support pipe 3. Joint plates 13 are welded at both ends of the diagonal support rods 12. The top of the diagonal support rods 12 is welded to the surface of the first support pipe 3 through the joint plates 13. Positioning plates 16 are welded on the front and back of the first support pipe 3 near the bottom end. A round support rod 15 is welded between the positioning plate 16 and the joint plate 13 at the bottom end of the diagonal support rod 12. Adjusting rods 5 are slidably connected to the inner walls of the first support pipe 3 and the second support pipe 4. A support seat 6 is welded to the top of the adjusting rod 5. An adjustable frame 7 is rotatably connected to the inner wall of the support seat 6. Through holes 10 are formed on the surface of the channel steel 1. A screw rod 11 is arranged on the inner wall of the through hole 10. A fixing bolt 17 is threadedly sleeved on the outer edge of the screw rod 11.

[0032] Among them; fasteners 8 are welded on both sides of the first support pipe 3 and the second support pipe 4. The shape of the fastener 8 is concave, and a clamping bin is left at the welding position of the fastener 8. By setting the fastener 8 and the reserved clamping bin, the first support pipe 3 and the second support pipe 4 can be movably clamped together, which can play a certain stabilizing effect and facilitate subsequent disassembly.

[0033] Among them; a reinforcing angle steel 9 is clamped in the inner wall of the clamping bin of the fastener 8. Square wedges are welded at both ends of the reinforcing angle steel 9, and the size of the wedge is adapted to the size inside the clamping bin of the fastener 8. Connecting each group of support members by using the reinforcing angle steel 9 increases the support capacity and stability of the jig.

[0034] Among them; the shape of the positioning plate 16 is inverted L-shaped, and the height of the inner wall at the inverted L bend of the positioning plate 16 corresponds to the height of the channel steel 1. Using the positioning plate 16 to span the groove on the side of the channel steel 1 and lap with it, so that the positioning plate 16 stabilizes the first support pipe 3 under the fixation of the fixing bolt 17.

[0035] Among them; a positioning block 14 is welded on the surface of the joint plate 13 at the bottom end of the diagonal support rod 12, and the size of the positioning block 14 is adapted to the size of the inner wall of the groove on the side of the channel steel 1. Using the support of the diagonal support rod 12 on the first support pipe 3, setting the positioning block 14 can increase the stability of the bottom support of the diagonal support rod 12 and prevent the first support pipe 3 from shaking.

[0036] Among them; a plurality of fixing holes 51 are formed on the surface of the adjusting rod 5, and the distances between adjacent fixing holes 51 correspond to the distances between the mounting holes on the surfaces of the first support pipe 3 and the second support pipe 4. Bolts are used to position the adjusting rod 5, so that the adjusting rod 5 can support the flexible frame 7 to fit the side of the hull, facilitating the support of hulls of different shapes.

[0037] Among them; the flexible frame 7 includes an angle frame 71. Transfer holes 72 and adjusting shaft holes 73 are respectively formed on the surface of the angle frame 71. The inner wall of the adjusting shaft hole 73 is an elliptical through groove. A backing plate 74 is welded to the top of the angle frame 71. The adjusting shaft hole 73 of the flexible frame 7 can adjust its inclination angle as the adjacent adjusting rod 5 rises or falls, so that the backing plate 74 of the flexible frame 7 fits more closely to the arc of the hull side, thereby reducing the damage to the outer wall of the hull during the support of the jig.

[0038] Among them; one end of the screw rod 11 respectively penetrates through the positioning plate 16, the joint plate 13 and the positioning block 14 and passes through the inside of the through hole 10 on the surface of the adjacent channel steel 1. The arranged channel steels 1 are connected in series by the screw rod 11 to form an integral jig, increasing the supporting capacity of the jig.

[0039] Among them; the fixing bolt 17 includes a first screw part 171 and a second screw part 172. Joint parts 173 are arranged on the sides of the first screw part 171 and the second screw part 172. A clamping block 174 is arranged at the bottom of the first screw part 171. A clamping groove 175 is formed at the top of the second screw part 172, and the shape of the clamping block 174 is adapted to the shape of the inner wall of the clamping groove 175. An auxiliary bolt 176 is threadedly connected to the outer edge of the joint part 173. The overall structure of the fixing bolt 17 is composed of the first screw part 171, the second screw part 172 and the joint part 173. Then, the stability of the splicing part of the fixing bolt 17 is increased by the clamping block 174 and the clamping groove 175, so that the fixing bolt 17 can be directly spliced at the fixing place, increasing the assembly efficiency of the jig.

[0040] Among them; adjacent first support pipes 3 and second support pipes 4 form a group of support members, and the height of each group of support members near the center of the jig gradually decreases. The first support pipe 3 and the second support pipe 4 are combined into a group of support members, so that the support points in the jig can support alternately, thereby increasing the supporting stability of the jig.

[0041] Working principle: When a splicing jig is needed to support the hull, first, a number of channel steels 1 are arranged on the barge deck. Then, the first support pipe 3 and the second support pipe 4 are respectively sleeved on the vertical support rods 2 at the top of the channel steel 1 and fixed with bolts. After that, the positioning block 14 at the bottom end of the inclined support rod 12 is snapped into the recess on the side of the adjacent channel steel 1, and the hole at its center is aligned with the position of the through hole 10, so that the first support pipe 3 and the second support pipe 4 are stably erected on the top of the channel steel 1, thus forming a single set of support members. After all the single set of support members are assembled into the local structure of the jig in order of height, the reinforcing angle steel 9 is snapped into the interior of the fastener 8 to connect the adjacent support members. Then, the screw rod 11 is passed through the through hole 10 to connect the support members and the channel steel 1 in series. Then, the fixing bolt 17 is used to fix the connection between the support members and the channel steel 1. Finally, according to the different models of the supported hull, the height of the adjusting rod 5 is adjusted by bolts, so that the angle formed by the movable frame 7 fits the radian of the bottom of the hull, thus completing the composition of the jig. After use, the jig is disassembled and stored according to the reverse steps above, which is convenient for subsequent use.

[0042] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
