Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding equipment, in particular to a mobile device for half-ship serial and parallel drift positioning piers. Background Art

[0002] The construction dock area of the "million-ton" shipbuilding base is limited. In order to improve the production continuity of the large dock, a series-parallel construction mode is adopted during the closure, that is, the dock is divided into two parallel lines on the east and west sides, and each line is divided into full ship positions and half ship positions for series construction. When the ship is first loaded, the stern half ship is built first. After the half ship is formed, it drifts to the stern of the dock for a second pier, and then the bow half ship section is hoisted. A series of stern half ships are built in the original ship position, forming a series-parallel cycle construction mode.

[0003] The drifting positioning of the half-ship is a key technology in the serial-parallel cycle construction mode. According to production needs, water is injected into the shipbuilding dock to float the welded stern half-ship, drag it to another designated location in the dock, accurately position it through tooling and measuring instruments, and then drain it and place it on the dock again. During the process, the placement of the dock pier is distributed in combination with the intersection of the longitudinal and transverse structures of the ship. Once the positioning of the half-ship deviates, the original design strength will fail, and the dock pier will not reach the strong structure of the hull, resulting in local deformation of the outer bottom plate, which may cause large-scale plate replacement. In addition, the center line and rib position line of the half-ship after it is placed on the pier do not coincide with the original dock bottom ground sample reference line, which will also cause the dock bottom ground sample line to be re-surveyed, and then segmented positioning will be carried out according to the new ground sample line, making continuous loading impossible, resulting in construction delays.

[0004] Furthermore, the required accuracy for the piers is ±10mm in the X direction, ±5mm in the Y direction, and ±8mm in the Z direction. Current traction equipment uses a winch, making it difficult to achieve these precisions while floating. Ensuring the accuracy and speed of hull movement during the semi-drift positioning of the piers is a bottleneck for this technology; improperly addressing this issue could negate the advantages of this model. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.

[0019] like Figures 1 to 4 The utility model includes a first moving mechanism and a second moving mechanism. The first moving mechanism includes a push rod 1 and a push drive mechanism 2. The push drive mechanism 2 is arranged at the edge of the dock. One end of the push rod 1 is hinged to the hull, and the other end can be pressed against the push drive mechanism 2. The push drive mechanism 2 can longitudinally press the push rod 1. The second moving mechanism can drive the hull to move laterally and pull the hull back longitudinally. Through the above arrangement, when the half-ship moves to the vicinity of the pier position, the second moving mechanism pulls the hull back along the edge of the dock, and the push mechanism pushes the hull outward, maintaining the combined force of the pull-back force and the push force to drive the hull to move, so that the longitudinal movement of the hull is controllable. The second moving mechanism can drive the hull to move laterally.

[0020] Furthermore, to prevent the push rod 1 from causing an obstruction, a lifting mechanism 3 and a connecting assembly are provided to facilitate the retraction of the push rod. The connecting assembly comprises a connecting seat 4, an arc-shaped support plate 5, and a hinge 6. The arc-shaped support plate 5 is located at the bottom end of the connecting seat 4. The bottom end of the push rod 1 is connected to the connecting seat 4 via the hinge 6. The top end of the push rod 1 is connected to the lifting mechanism 3 via a steel wire rope. The lifting mechanism 3 can use the steel wire rope to drive the push rod 1 to retract and extend. The connecting seat 4 is fixed to the side plate of the hull. Lugs 7 are provided on both sides of the connecting seat 4. The second movable mechanism is connected to the lugs 7 on both sides. When the lifting mechanism 3 lowers the steel wire rope, the top end of the lift rod swings outward until the lift rod is in a horizontal position. The bottom end of the lift rod falls onto the support plate 5 and then docks with the push drive mechanism 2, allowing the push drive mechanism 2 to contact the bottom end of the lift rod. The push drive mechanism 2 pushes the push rod 1.

[0021] To achieve lateral movement of the hull, the second movement mechanism includes two winches 8, which are fixed to the edge of the dock and are respectively arranged on both sides of the thrust drive mechanism 2. The two winches 8 are connected to the hanging lugs 7 by steel cables 9. By adjusting the movement of the two winches, the combined force of the steel cables 9 pulling on the hanging lugs 7 causes the hull to move laterally.

[0022] In order to prevent the top of the push rod 1 from scraping the side edge of the dock during lateral movement and to reduce the friction of lateral movement, an anti-friction mechanism is provided at the top of the push rod 1. The anti-friction mechanism includes a support frame 10 and a pressure roller 11. The support frame 10 is fixed to the top of the push rod 1. The pressure roller 11 is connected to both sides of the support frame 10 via a rotating shaft and protrudes from the support frame 10. The pressure roller 11 contacts the side edge of the dock.

[0023] The pushing drive mechanism 2 comprises a pushing cylinder 12. The end of the pushing rod 1 is further provided with a pushing limit groove 13 and a guide groove 14. The pushing limit groove 13 is provided at the top of the pushing rod 1, and the guide groove 14 is perpendicular to the pushing limit groove 13 and is arc-shaped. The rod of the pushing cylinder 12 first falls into the guide groove 14 and then reaches the pushing limit groove 13, allowing the rod of the pushing cylinder 12 to accurately push against the end of the pushing rod 1. This improves the accuracy of the aligning of the pushing cylinder 12 with the end of the pushing rod 1.

[0024] The working process is as follows: the hull moves to the approximate position of the pier in a floating state, then the push rod is lowered, the pressure cylinder is pressed against the limit slot, the wire rope is connected to the lug and winch, and the longitudinal adjustment of the hull is carried out through the expansion and contraction of the pressure cylinder and the combined force of the wire rope. The action of the winches on both sides can jump the length of the wire rope on both sides of the lug, thereby adjusting the precise position of the hull. After the adjustment, the pressure cylinder contracts, the push rod will be retracted to the side of the hull, and the connection between the wire rope, the winch and the lug can be disconnected.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
