Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipbuilding technology, specifically a tilting platform for edge operations. Background Technology
[0002] In shipbuilding processes, when the crane is installed in a dry dock with a detachable dock gate, and the crane is embedded in the main structure of the dock gate and welded to it, or when the crane is installed in a way that is close to the water or adjacent to the side, the crane operator often encounters operational difficulties during the installation and lifting of the shackles.
[0003] Currently, the narrow working space obstructs visibility due to the dock gate structure, and the damp water environment and the reflection of the metal structure further interfere with the accuracy of operation. When working near the edge, personnel must maintain unnatural working postures such as leaning, tiptoeing, or hanging in the edge area without effective protection. They must not only cope with the dynamic tension of the hoisting equipment, but also face the high risk of falling into the water at the bottom of the dock or the gap of the edge structure. Even a slight deviation in operation may cause safety accidents such as equipment damage and personnel injury. Utility Model Content
[0004] The purpose of this invention is to provide a near-edge operation flipping platform to solve the problems raised in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tilting platform for edge operations, comprising a platform plate one, a lifting ring, a screw, a platform plate two, and side connecting arms. The lifting ring is connected to the outer side of the platform plate one, and the screw is connected through the outer side of the lifting ring. A tilting mechanism is provided on one side of the platform plate one. The tilting mechanism connects the platform plate two to the outer side of the rotating shaft through the side connecting arms on both sides according to the usage requirements. Thus, according to the usage requirements, the platform plate two is in a horizontal state after tilting or the tilting platform is pulled up and the inserted pin is in a vertical state. A protective mechanism is provided on one side of the platform plate two. The protective mechanism engages with a protective rod on one side of the platform plate two, thereby using multiple sets of protective rods to protect the other side of the platform plate two.
[0006] As a preferred technical solution, the folding mechanism includes a rotating shaft, a stiffening plate, an ear plate, a fastening hole, a pin hole, a side support plate, and a side connecting arm. The side connecting arm is connected to the outer side of the rotating shaft. The side connecting arm is symmetrically welded to the outer side of the second platform plate. A stiffening plate is provided on one side of the second platform plate. The bottom end of the stiffening plate is welded to the top end of the first platform plate. The side support plate is welded to the top end of the first platform plate. The ear plate is symmetrically welded to the top end of the second platform plate. A fastening hole is provided through the outer side of the ear plate. A pin hole is symmetrically provided through the one side of the stiffening plate.
[0007] As a preferred technical solution, the platform plate is connected to the outer side of the rotating shaft through symmetrically arranged ear plates, and both sides of the ear plates adopt a chamfered structure.
[0008] As a preferred technical solution, the stiffening plate is welded to the top of the platform plate by a side support plate welded on one side.
[0009] As a preferred technical solution, the protective mechanism includes a platform plate two, a rod base, a protective rod, and a slot. The platform plate two has rod bases evenly spaced on one side, the bottom of the rod base has a slot, and the top of the rod base is connected to the protective rod at equal intervals.
[0010] As a preferred technical solution, the rod base is engaged with one side of the platform plate two through a slot opened at the bottom.
[0011] As a preferred technical solution, a pin hole is symmetrically opened on one side of the stiffening plate to connect with the outer side of the screw, and the screw is connected to the outer side of the lifting ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides crane operators with a standing space that is adapted to the height of the crane and has sufficient area through the flip-up horizontal operating platform plate. This allows them to complete the installation and tightening of shackles and nuts in a natural posture, greatly reducing the time required to adjust their body posture and improving work efficiency. When in use, it unfolds into an operating platform, and when not in use, it folds up into a vertical state close to the crane, completely freeing up space in adjacent water or edge areas, avoiding interference with on-site logistics and personnel passage, and significantly improving the overall utilization rate of the construction site.
[0013] 2. This utility model uses a platform plate made of "Z" patterned plate, which not only ensures structural strength, but also improves anti-slip performance through the surface pattern. When the platform is horizontal, the guardrail forms a physical barrier to prevent the crane operator from tipping it over to water or the edge. When stored vertically, the platform is close to the structural surface to avoid occupying external space and reduce the risk of accidental collision. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figures 1 to 5 As shown, this utility model provides the following technical solution: a tilting platform for edge operation, including a platform plate 1, a lifting ring 3, a screw 4, a platform plate 7, and side connecting arms 16. The lifting ring 3 is connected to the outer side of the platform plate 1, and the screw 4 is connected through the outer side of the lifting ring 3. A tilting mechanism 5 is provided on one side of the platform plate 1. The tilting mechanism 5 connects the platform plate 7 to the outer side of the rotating shaft 2 through the side connecting arms 16 on both sides according to the usage requirements. Thus, according to the usage requirements, the platform plate 7 is in a horizontal state after tilting or the tilting platform is pulled up and the inserted pin is in a vertical state. A protective mechanism 10 is provided on one side of the platform plate 7. The protective mechanism 10 engages one side of the platform plate 7 with a protective rod 9, thereby using multiple sets of protective rods 9 to protect the other side of the platform plate 7.
[0018] Platform plate 1 has “7” shaped ear plates 12 welded on both sides, and fastening holes 13 are opened on the ear plates 12. Platform plate 2 has side connecting arms 16 welded on both sides. By rotating shaft 2 or passing through the holes of ear plates 12 and side connecting arms 16 and locking with nuts, platform plate 2 is hinged to platform plate 1. At this time, platform plate 2 can rotate freely around the axis.
[0019] like Figure 1 , Figure 2 and Figure 3As shown, the folding mechanism 5 includes a rotating shaft 2, a stiffening plate 6, an ear plate 12, a fastening hole 13, a pin hole 14, a side support plate 11, and a side connecting arm 16. The side connecting arm 16 is connected to the outer side of the rotating shaft 2. The side connecting arm 16 is symmetrically welded to the outer side of the platform plate 2 7. A stiffening plate 6 is provided on one side of the platform plate 2 7. The bottom end of the stiffening plate 6 is welded to the top end of the platform plate 1. The side support plate 11 is welded to the top end of the platform plate 1. The ear plate 12 is symmetrically welded to the top end of the platform plate 2 7. A fastening hole 13 is provided through the outer side of the ear plate 12. A pin hole 14 is symmetrically provided through one side of the stiffening plate 6. The platform plate 1 is connected to the outer side of the rotating shaft 2 through the symmetrically arranged ear plates 12. Both sides of the ear plates 12 adopt a chamfered structure. The stiffening plate 6 is welded to the top end of the platform plate 1 through the side support plate 11 welded to one side.
[0020] Specifically: the relative positions of the locking screw 4 and the lifting ring 3 are locked by the pin to prevent the platform from accidentally overturning due to external forces such as hoisting vibration, thus forming a stable horizontal operating platform. The vertical posture of the platform plate 7 is locked to prevent it from overturning again due to its own weight or wind force, and the space in the adjacent water or side area is completely released to avoid interference with other operations.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the protective mechanism 10 includes a platform plate 7, a rod base 8, a protective rod 9, and a slot 15. The rod base 8 is provided at equal intervals on one side of the platform plate 7. The bottom end of the rod base 8 is provided with a slot 15. The top end of the rod base 8 is connected to the protective rod 9 at equal intervals. The rod base 8 is engaged with one side of the platform plate 7 through the slot 15 at its bottom end. The reinforcing plate 6 is symmetrically provided with a pin hole 14 on one side to connect with the outside of the screw 4. The screw 4 is connected to the outside of the lifting ring 3.
[0022] Specifically, the pole base 8 is engaged and fixed to the platform plate 7 via the bottom slot 15, which facilitates quick assembly and disassembly. Multiple guard rods 9 are welded at equal intervals to the top of the pole base 8 to form a continuous guardrail. When the platform plate 7 is in a horizontal state, the guard rods 9 are higher than the upper surface of the platform plate 7, providing edge protection for the crane operator and preventing him from falling into the dock water or edge gap due to center of gravity shift or operational errors.
[0023] The working principle of this utility model is as follows: Platform plate 1 serves as the basic support structure. Lifting rings 3 are welded to the outer side for hoisting, and bolts 4 are used for locking. The inner side is fixed by welding stiffening plates 6, which are connected to the lifting rings 3 via their outer sides. They are connected to platform plate 7 via symmetrically arranged ear plates 12 and side connecting arms 16. The bottom end of the stiffening plates 6 is directly welded to the top of platform plate 1, enhancing the rigid connection between the two layers. A side support plate 11 is also welded to the top of platform plate 1, providing support by welding the side support plate 11 to one side of the stiffening plate 6. When the crane operator needs to install the shackles on platform plate 27, they manually or with auxiliary tools push platform plate 27 to rotate around the bolts until it flips from a vertical position to a horizontal position, thus forming the working position. To ensure the stability of the horizontal position, after platform plate 27 is flipped into place, the square pads on the crane are adjusted to fit the "U"-shaped grooves, and the pads are used to press against the bottom surface of platform plate 27 to restrict its continued rotation. At the same time, the screw 4 is passed through the pin hole 14 of platform plate 1 and connected to the lifting ring 3 through the outside of platform plate 1. When the tilting platform is not in use, after the hoisting operation is completed or when it is necessary to release the adjacent water or side space, the lifting ring 3 in the middle of the platform plate 1 is inserted through the screw 4, and the lifting ring 3 is pulled upward, so that the lifting ring 3 separates from the stiffening plate 6, causing the platform plate 7 to rotate in the opposite direction around the pivot 2, folding from the horizontal state to the vertical state close to the crane or dock gate structure. At this time, the bottom surface of the platform plate 7 contacts the surface of the stiffening plate 6, reducing the space occupied; at the same time, the pin is inserted into the pin hole 14 of the platform plate 1 and cooperates with the screw 4 to lock the vertical posture of the platform plate 7.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
