Description

Technical Field

[0001] The utility model relates to the technical field of ship launching, and more specifically, to an auxiliary tooling for transverse movement of an extra-long ship. Background Art

[0002] During the construction of small and medium-sized ships, the mechanical longitudinal launching method is as follows: after the ship is built on the land slipway, it must be moved longitudinally from the slipway to the transverse shifting row (or transverse shifting vehicle), and the transverse shifting row carries the entire ship transversely. After aligning it with the launching slide, the ship is launched along the launching slide with a certain slope.

[0003] When the weight and length of the vessel being built are within the load range of the traverse rails, the safety of the traverse process is guaranteed. However, when the length of the vessel being built exceeds the traverse rails by a significant amount, for example, by more than 90% of the length, that is, when a 50-meter traverse rail is carrying a 95-meter-long vessel, the portion that exceeds the traverse rails is 45 meters long. If the weight of the excess portion is not supported, its center of gravity will generate a huge tipping moment, causing deformation, overload, and even pitching risks to the ship lifting trolleys at the ends of the traverse rails, as well as the ends and surrounding hull structures. The usual practice is to carry out technical modifications and lengthen the traverse rails, but this involves huge investments in equipment, infrastructure, land, and capital, and can interrupt production continuity. The cost is too high, and sometimes orders have to be abandoned.

[0004] The applicant's prior application, patented technology with publication number CN102730169B, discloses a ship launching and transverse movement auxiliary device, comprising a ship lifting trolley and a trolley track. The ship lifting trolley is arranged on the trolley track. The ship lifting trolley is provided with a ship moving track. One end of the ship moving track is the river end A close to the river surface. The device also comprises an auxiliary transverse movement track, a detachable movable track frame and a transverse movement trolley. The detachable movable track frame is arranged next to the river end A of the ship moving track. The auxiliary transverse movement track is installed on the top of the detachable movable track frame. The transverse movement trolley is arranged on the auxiliary transverse movement track. The present invention has a fast construction period, low labor intensity, saves manpower and material resources, has good practicality and safety, is easy to disassemble and maintain, can effectively improve the launching capacity of the shipyard, and can increase the length of the launched ship by 30 meters.

[0005] The auxiliary lateral movement track of the existing ship launching and lateral movement auxiliary device is usually fixedly installed, so the auxiliary lateral movement trolley can only be supported at a fixed position of the extra-long part of the hull. However, the length of the extra-long hull is different for each ship, and the existing auxiliary lateral movement trolley cannot be adjusted according to the length of the extra-long part of the hull, which easily leads to the problem of unsatisfactory support effect.

[0006] Therefore, it is urgent to design an auxiliary tooling for the transverse movement of ultra-long ships to solve the above technical problems. Utility Model Content

[0007] The technical problem to be solved by the present invention is to provide an extra-long ship transverse movement auxiliary tooling for the above-mentioned deficiencies in the prior art, which can effectively support extra-long parts of the hull of different lengths and has a wider range of applications.

[0008] The technical solution of the present utility model is as follows: an auxiliary tooling for the transverse movement of an extra-long ship, comprising an auxiliary transverse movement track and an auxiliary transverse movement trolley, the auxiliary transverse movement track comprising a steel plate, a T-shaped steel rail and a track body, the steel plate being pre-buried in the ground on one side of the transverse movement row, a plurality of T-shaped steel rails, and the plurality of T-shaped steel rails being welded on the top of the steel plate in parallel and at intervals, the plurality of T-shaped steel rails being parallel to the transverse movement row, a total of two track bodies, the two track bodies being vertically laid on the tops of the plurality of T-shaped steel rails, and a connecting plate being welded and fixed on both sides of the track body corresponding to each of the T-shaped steel rails, two locking nuts being slidably installed in each of the T-shaped steel rails, a fastening bolt being inserted on each of the connecting plates, and the fastening bolts being sequentially passed through the connecting plate and the T-shaped steel rail and being threadedly connected to the locking nuts one by one; the auxiliary transverse movement trolley is slidably installed on the two track bodies.

[0009] As a further improvement, concrete is laid on the top of the steel plate, and the bottom of the track body is in contact with the top surface of the concrete.

[0010] Furthermore, the track body is a segmented structure.

[0011] Furthermore, a plurality of pads are movably placed on the auxiliary transverse movement trolley.

[0012] Furthermore, the auxiliary transverse movement trolley includes a support frame and a plurality of running wheels, each of the running wheels is hingedly mounted on the bottom of the support frame, and the rotation direction of the running wheel is the same as the extension direction of the track body.

[0013] Furthermore, the number of running wheels on one side of the support frame is greater than the number of running wheels on the other side, and the side of the support frame with more running wheels is arranged toward the side of the water slide.

[0014] Beneficial effects

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

[0016] 1. The auxiliary tooling for the transverse movement of an extra-long ship of the present invention installs the track body by arranging a T-shaped steel rail on one side of the transverse row. During actual use, the position of the track body can be adjusted by loosening the fastening bolts so that the track body is located below the center of gravity of the extra-long part of the hull, thereby allowing the auxiliary transverse movement trolley to be more accurately supported at the center of gravity of the extra-long part of the hull, and can effectively support extra-long parts of different lengths of the hull. It has a wider range of applications and makes the force on the hull more uniform, effectively protecting the hull while greatly improving the transverse stability of the hull.

[0017] 2. The auxiliary tooling for the transverse movement of super-long ships of the present invention adopts an auxiliary transverse movement trolley with wheels that can swing in the transverse movement direction to support the super-long part of the hull, and cooperates with the transverse movement row to move the hull transversely to the launching slide. During the transverse movement process, when it moves transversely to the inclined auxiliary transverse movement track, the wheels swing relative to the top of the auxiliary transverse movement trolley, keeping the auxiliary transverse movement trolley deck horizontally in the transverse movement direction, thereby keeping the hull horizontal, and being able to smoothly move the super-long ship transversely into the water, effectively improving work efficiency.

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0030] See Figure 1-9 The utility model is an auxiliary tool for the transverse movement of an ultra-long ship, comprising an auxiliary transverse movement track and an auxiliary transverse movement trolley 1, wherein the auxiliary transverse movement track comprises a steel plate 2, a T-shaped steel rail 3 and a track body 4, the steel plate 2 is pre-buried in the ground on one side of the transverse movement row 5, the T-shaped steel rail 3 is a steel rail with an inverted "T" shape in the inner cavity, and there are a plurality of them, and the plurality of T-shaped steel rails 3 are welded to the top of the steel plate 2 in parallel and at intervals, the plurality of T-shaped steel rails 3 are parallel to the transverse movement row 5, and there are two track bodies 4, which are adapted to the running wheels 12 of the auxiliary transverse movement trolley 1, and the two track bodies 4 are laid vertically on the plurality of T-shaped steel rails 3 The top, that is, the extension direction of the two track bodies 4 is toward the side of the launch slide 13, and connecting plates 6 are welded and fixed on both sides of the track body 4 corresponding to each T-shaped steel rail 3, and two locking nuts 7 are slidably installed in each T-shaped steel rail 3, and each connecting plate 6 is inserted with a fastening bolt 8, and the fastening bolt 8 passes through the connecting plate 6 and the T-shaped steel rail 3 in turn and is threadedly connected with the locking nut 7 one by one, so as to fix the track body 4 on the T-shaped steel rail 3; the auxiliary transverse movement trolley 1 is slidably installed on the two track bodies 4, so that the auxiliary transverse movement trolley 1 can slide along one side of the launch slide 13.

[0031] The super-long ship transverse movement auxiliary tooling of the present invention installs the track body 4 by setting a T-shaped steel rail 3 on one side of the transverse row. During actual use, the position of the track body 4 can be adjusted by loosening the fastening bolts 8 so that the track body 4 is located below the center of gravity of the super-long part of the hull 14, so that the auxiliary transverse movement trolley 1 can be more accurately supported at the center of gravity of the super-long part of the hull 14, and can effectively support the super-long parts of different lengths of the hull 14, with a wider range of applications. It also makes the force on the hull 14 more uniform, effectively protects the hull 14, and greatly improves the transverse stability of the hull.

[0032] Preferably, concrete 9 is laid on the top of the steel plate 2 to pre-embed the steel plate 2 in the ground. At the same time, the bottom of the track body 4 fits with the top surface of the concrete 9, so that the contact area between the track body 4 and the ground is larger, thereby improving the installation stability of the track body 4 and further improving the lateral stability of the hull.

[0033] Preferably, the track body 4 is a segmented structure. Since the ultimate purpose of the lateral movement of the hull 14 is to align with the sloped launching slide 13, the stern gradually descends downhill. The segmented structure makes it convenient to install the track body 4 on the sloped ground, and also facilitates the movement and alignment one by one.

[0034] Preferably, a plurality of pads 10 are movably placed on the auxiliary transverse movement trolley 1. Since the stern of the hull 14 is usually an irregular slope, by adding or reducing the pads 10, the auxiliary transverse movement trolley 1 can better contact with the hull 14 to form support.

[0035] Preferably, the auxiliary transverse movement trolley 1 includes a support frame 11 and a plurality of running wheels 12 , wherein each running wheel 12 is hingedly mounted on the bottom of the support frame 11 , and the rotation direction of the running wheel 12 is the same as the extension direction of the track body 4 .

[0036] The extra-long ship transverse movement auxiliary tooling of this embodiment adopts an auxiliary transverse movement trolley 1 with running wheels 12 that can swing in the transverse movement direction to support the extra-long part of the hull 14, and cooperates with the transverse movement row 5 to move the hull 14 transversely to the launching slide 13. During the transverse movement process, when it moves transversely to the inclined auxiliary transverse movement track, the running wheels 12 swing relative to the top of the auxiliary transverse movement trolley 1, keeping the auxiliary transverse movement trolley 1 horizontally in the transverse movement direction, so that the hull remains horizontal, and the extra-long ship can be smoothly moved transversely into the water, effectively improving work efficiency.

[0037] Preferably, the number of running wheels 12 on one side of the support frame 11 is greater than the number of running wheels 12 on the other side, and the side of the support frame 11 with more running wheels 12 is arranged toward the launch ramp 13. Since the stern of the hull 14 tends to gradually descend during lateral movement, the center of gravity of the hull 14 tends to be biased toward the launch ramp 13. In this case, the number of running wheels 12 arranged toward the launch ramp 13 is relatively greater, thereby further improving lateral stability.

[0038] The method for launching an ultra-long ship transversely in this embodiment includes the following steps:

[0039] S1: Install the auxiliary transverse trolley 1 on the auxiliary transverse track below the extra-long portion of the hull 14 to support the extra-long portion of the hull 14, and install the boat lifting trolley 15 on the launching slide 13 corresponding to the end of the auxiliary transverse track;

[0040] S2: Connect the lateral traction rope of the lateral winch to the lateral row 5 and the auxiliary lateral trolley 1 at the same time;

[0041] S3: Start the transverse winch to drive the transverse row 5, the hull 14, and the auxiliary transverse trolley 1 to move transversely to the side of the launching slide 13 at the same time, until the hull 14 moves transversely to the launching slide 13 and the auxiliary transverse trolley 1 moves transversely to the boat lifting trolley 15;

[0042] S4: The auxiliary lateral movement trolley 1 is fixedly connected to the boat lifting trolley 15, the launching traction rope of the launching winch is connected to the hull 14 and the boat lifting trolley 15 at the same time, and the lateral movement traction rope of the auxiliary lateral movement trolley 1 is loosened;

[0043] S5: The launching winch is started, and the launching traction rope of the launching winch is slowly loosened. The hull 14 and the boat lifting trolley 15 slowly slide down the launching slide 13 under the action of their own gravity until the boat lifting trolley 15 contacts the water surface of the river;

[0044] S6: The launching traction rope of the hull 14 is released, and the hull 14 falls into the river channel, completing the lateral launching of the super-long hull.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
