Description

Technical Field

[0001] The utility model relates to the field of ship structures, in particular to a lifting bracket for a hydraulic shipbuilding berth trolley. Background Art

[0002] The hydraulic shipbuilding berth trolley is a commonly used equipment in shipbuilding on a horizontal shipbuilding berth. By using the hydraulic shipbuilding berth trolley, the hull or section can be conveniently lifted and transferred to a designated location for assembly or launching.

[0003] During the actual ship transfer process, since the trolley track is not absolutely horizontal, the lifting force also changes greatly accordingly. When the hydraulic shipbuilding berth trolley is not overloaded, the ship bottom plate will also be sunken. This is obviously caused by the compressive instability deformation of the web of the longitudinal girder and rib plate at the ship bottom. And the hydraulic shipbuilding berth trolley cannot bear the weight of the hull for a long time after the ship transfer. Therefore, it is necessary to change to a fixed pier. Especially after the ship is moved to the floating dock, the shipbuilding berth trolley is an electromechanical equipment and cannot be launched with the ship. Therefore, the pier must be changed, and then the hydraulic shipbuilding berth trolley is withdrawn from the ship bottom. However, changing the pier is a heavy physical labor. Before the transformation of the lifting frame, when changing the pier, the inclined sleeper is driven into contact with the ship hull, which is very easy to damage the ship bottom paint and cause unnecessary losses such as increased painting costs.

[0004] Therefore, there is an urgent need to propose a lifting bracket for a hydraulic shipbuilding berth trolley with stronger bearing capacity and more solid structure. Summary of the Utility Model

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a lifting bracket for a hydraulic shipbuilding berth trolley with stronger bearing capacity and more solid structure.

[0006] The technical implementation scheme of the utility model is: a lifting bracket for a hydraulic shipbuilding berth trolley, which includes a trolley support plate, reinforcing ribs, a top plate, an installation ring and a connecting seat. The trolley support plate is the installation carrier for each component. The bottom of the trolley support plate adopts a variable cross-section structure, and the cross-sections at both ends of the bottom of the trolley support plate are smaller than the middle cross-section. The reinforcing ribs are arranged inside the trolley support plate and are arranged in a cross shape. The top plate is arranged at the middle position inside the lower part of the trolley support plate. The installation ring is arranged at the bottom of the top plate, and the outer side of the installation ring is connected to the wall surface inside the lower part of the trolley support plate. The connecting seat is rotatably and slidably arranged at the inner bottom of the installation ring.

[0007] In addition, particularly preferably, a cavity is opened inside the trolley support plate, and the reinforcing ribs are located in the cavity and have equidistant intervals.

[0008] In addition, particularly preferably, the equidistant intervals between the cross-shaped reinforcing ribs make the overall reinforcing ribs form a triangular steel structure.

[0009] In addition, particularly preferably, a plurality of rectangular grooves are symmetrically opened along the axial direction on the inner wall surface of the installation ring.

[0010] In addition, it is particularly preferred that it further includes a guide rod, a push block and a spring. The guide rod is symmetrically arranged at the upper part inside the rectangular groove; the push block is slidably arranged outside the guide rod, and the connecting seat is in sliding contact with the upper push block; the spring is arranged between the inner wall surface of the rectangular groove and the push block.

[0011] In addition, it is particularly preferred that there are several guide rods, push blocks and springs corresponding to the rectangular groove.

[0012] In addition, it is particularly preferred that the bottom of each push block is inclined.

[0013] In addition, it is particularly preferred that a mating groove is formed in the lower part inside the mounting ring, and the upper part of the connecting seat is rotatably arranged in the mating groove.

[0014] In addition, it is particularly preferred that the upper part of the connecting seat is symmetrically provided with notches corresponding to each push block.

[0015] In addition, it is particularly preferred that several symmetric mounting holes are formed in the bottom inside the connecting seat.

[0016] The utility model has the following advantages: 1. The variable cross-section design of the trolley tray in the utility model helps to better disperse the load, reduce the uneven stress on the hull on the non-horizontal track, thereby avoiding the depression of the ship bottom plate; the triangular steel structure significantly enhances the overall rigidity of the bracket and can effectively resist the torsional force generated during the non-horizontal movement.

[0017] 2. In the utility model, the push block abuts against the telescopic end of the hydraulic ship platform trolley under the action of the spring to ensure the stability during the movement, and at the same time, the elasticity of the spring ensures the close contact between the bracket and the hull.

[0018] 3. In the utility model, by rotating the connecting seat to align the notch with the lower part of the rectangular groove, the push block can be easily reset, and then the bracket can be conveniently separated from the hydraulic ship platform trolley, reducing the operation difficulty.

[0019] 4. The utility model avoids the use of traditional manual pier-changing methods such as inclined sleepers, reduces the potential damage to the ship bottom paint, and reduces the painting cost and maintenance cost.

[0020] 5. The utility model greatly shortens the pier-changing time through the quick installation and disassembly mechanism of the bracket and the hydraulic ship platform trolley, improving the overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Embodiment: Hydraulic trolley boat lifting bracket, such as Figures 1-6As shown in the figure, it includes a trolley pallet 1, reinforcing ribs 2, a top plate 3, a mounting ring 30 and a connecting seat 4. The trolley pallet 1 is the mounting carrier for each component. The bottom of the trolley pallet 1 adopts a variable surface structure, and the cross-sections at both ends of the bottom of the trolley pallet 1 are smaller than the middle cross-section, which helps to disperse the load and reduce the uneven stress on the hull on the non-horizontal track, thus avoiding the depression of the ship bottom plate. A cavity 11 is provided inside the trolley pallet 1. The reinforcing ribs 2 are located inside the cavity 11 and have equidistant intervals, which can improve the overall rigidity and stability of the bracket and resist the torsional force caused by non-horizontal movement. The reinforcing ribs 2 are arranged inside the trolley pallet 1 and are arranged in a cross shape. The equidistant intervals between the cross-arranged reinforcing ribs 2 form a triangular steel structure 21 as a whole for the reinforcing ribs 2. The top plate 3 is arranged at the middle position in the lower part of the trolley pallet 1. The mounting ring 30 is arranged at the bottom of the top plate 3, and the outer side of the mounting ring 30 is connected to the wall surface in the lower part of the trolley pallet 1. A number of rectangular grooves 31 are symmetrically arranged along the axial direction on the inner wall surface of the mounting ring 30, and the rectangular grooves 31 are used to accommodate and mount subsequent components. The connecting seat 4 is rotatably and slidably arranged at the inner bottom of the mounting ring 30. Corresponding notches 41 for each push block 33 are symmetrically arranged at the upper part of the connecting seat 4. A number of symmetrically arranged mounting holes 42 are provided at the inner bottom of the connecting seat 4. A mating groove 35 is provided in the lower part of the mounting ring 30, and the upper part of the connecting seat 4 is rotatably arranged in the mating groove 35.

[0031] As Figures 3-5 and Figure 7 shown in the figure, it further includes a guide rod 32, a push block 33 and a spring 34. The guide rods 32 are symmetrically arranged at the upper part inside the rectangular grooves 31. The push blocks 33 are slidably arranged on the outer sides of the guide rods 32. The connecting seat 4 is in sliding contact with the upper push blocks 33. The bottom of each push block 33 is inclined. The springs 34 are arranged between the inner wall surfaces of the rectangular grooves 31 and the push blocks 33 and are used to provide a restoring force to ensure that the push blocks 33 can always be in close contact with the hull during the movement of the hull and maintain a good contact state. The elastic action of the springs 34 ensures the stable connection between the bracket and the hull. There are several guide rods 32, push blocks 33 and springs 34 corresponding to the rectangular grooves 31.

[0032] During operation, align the mounting ring 30 of the trolley tray 1 with the telescopic end of the hydraulic shipway trolley to fit and install the two to prevent the trolley from slipping. Before the telescopic end of the hydraulic shipway trolley contacts the inner wall of the mounting ring 30, the telescopic end of the hydraulic shipway trolley first contacts the bottom surface of the connecting seat 4, causing the connecting seat 4 to slide upward continuously as the telescopic end of the hydraulic shipway trolley aligns and connects with the mounting ring 30. During the sliding, all the push blocks 33 above are simultaneously pushed inward. The push blocks 33 slide smoothly along the guide rods 32 and drive the springs 34 to stretch and deform. Then, after the telescopic end of the hydraulic shipway trolley is docked with the mounting ring 30, the push blocks 33 at this time will also abut against the outside of the telescopic end of the shipway trolley to fix it, and the fixing state is made more stable by the stretching force of the springs 34. Since the trolley tray 1 adopts a variable cross-section design, it helps to disperse the load during the process of supporting the ship bottom, reducing the uneven force on the hull on the non-horizontal track, thereby avoiding the depression of the ship bottom plate. Further, the triangular steel structure 21 in the cavity 11 of the trolley tray 1 increases the overall rigidity of the bracket and can also effectively resist the torsional force caused by non-horizontal movement. When it is necessary to separate the trolley tray 1 from the hydraulic shipway trolley, rotate the connecting seat 4 so that the notch 41 on the connecting seat 4 aligns with the lower part of each rectangular groove 31. At this time, the end face of the connecting seat 4 will no longer contact the push blocks 33, but let the push blocks 33 reset by the self-shrinking force of the springs 34 and drive the push blocks 33 to slide back, so that the legs no longer abut against the outside of the telescopic end of the hydraulic shipway trolley. At this time, the separation step can be carried out. Due to the overall function of the trolley bracket, the labor intensity of the operator is reduced, and the ship bottom paint is effectively prevented from being damaged during pier change, making ship movement and pier change more convenient.

[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
