Description

Technical Field

[0001] This utility model relates to the field of protective platform technology, and in particular to a flip-up protective platform. Background Technology

[0002] For lift-off dock gates, a lifting gantry is required on the deck. To avoid safety passages and minimize the weight of the lifting gantry, a structural lifting gantry is typically used, positioned on the outer side of the deck at the hull side. Due to the overall height of the dock gate, safety railings are required on both the upstream and downstream sides of the hull; therefore, the lifting gantry will be located outside these railings.

[0003] Because the distance between the guardrail and the structural crane is small, the guardrail is easily damaged when using the structural crane for hooking and hoisting. It is relatively safer for personnel to operate on the inside, but the guardrail structure itself will obstruct personnel operation and make it inconvenient to hook. If operating on the outside of the guardrail, not only is the space small, but the safety hazards are also greater. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that guardrails in the prior art obstruct the installation and use of the crane, resulting in inconvenience in use, and thus provide a flip-up protective platform.

[0005] To solve the above-mentioned technical problems, this utility model provides a flip-up protective platform, comprising:

[0006] The first flipping mechanism includes: a first railing, a support, a first fastener, and a first rotating shaft. The first end of the first railing is rotatably connected to the support via the first rotating shaft. The first fastener is disposed on the first railing and can be locked or unlocked from the support.

[0007] The second flipping mechanism includes a second railing, a second rotating shaft, and a connecting rod. The second railing is rotatably connected to the second end of the first railing via the second rotating shaft. The first railing has a sliding groove. One end of the connecting rod is rotatably connected to the second railing, and the other end is movably connected to the sliding groove.

[0008] In one embodiment of this utility model, the second rotating shaft is provided with a second fastener, which enables the second railing to rotate or be fixed to the second end of the first railing.

[0009] In one embodiment of this utility model, the plane on which the second railing is located can be perpendicular to or parallel to the plane on which the first railing is located.

[0010] In one embodiment of this utility model, a fixed railing is also included, which is respectively disposed on both sides of the first railing.

[0011] In one embodiment of the present invention, a support rod is further included, one end of which is detachably installed on the second railing and the other end of which is detachably installed on the fixed railing.

[0012] In one embodiment of this utility model, the second railing and the fixed railing are respectively equipped with a plurality of positioning posts along the height direction when open, and the two ends of the support rod are respectively provided with slots adapted to the positioning posts.

[0013] In one embodiment of the present invention, the first railing includes: a frame and a support frame, wherein the support frame is fixedly disposed within the frame and the support frame is a grid support frame.

[0014] In one embodiment of this utility model, the support is provided with an arc-shaped groove, the center of which is the axis of the first rotating shaft.

[0015] In one embodiment of this utility model, both the first fastener and the second fastener include a bolt and a nut, wherein the nut is threaded onto the bolt.

[0016] In one embodiment of the present invention, the second railing includes an extension and a support.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Example

[0029] Reference Figures 1-6 As shown, the present invention provides a flip-up protective platform, comprising:

[0030] The first flipping mechanism includes: a first railing 3, a support 2, a first fastener 6, and a first rotating shaft 7. The first end of the first railing 3 is rotatably connected to the support 2 through the first rotating shaft 7. The first fastener 6 is disposed on the first railing 3 and can be locked or unlocked to the support 2.

[0031] The second flipping mechanism includes a second railing 5, a second rotating shaft 8, and a connecting rod 4. The second railing 5 is rotatably connected to the second end of the first railing 3 via the second rotating shaft 8. The first railing 3 has a sliding groove. One end of the connecting rod 4 is rotatably connected to the second railing 5, and the other end is movably connected to the sliding groove.

[0032] The present invention discloses a reversible protective platform, wherein a support 2 provides rotational support for a first railing 3, a first rotating shaft 7 is mounted on the support 2 and the first railing 3 is rotatably connected to the first rotating shaft 7, or the first rotating shaft 7 is fixed to the first railing 3 and rotatably connected to the support 2, so that the first end of the first railing 3 is rotatably connected to the support 2 via the first rotating shaft 7, and a first fastener 6 allows the first railing 3 to be locked when rotated to a set angle. Similarly, a second railing 5 is rotatably connected to the second end of the first railing 3 via a second rotating shaft 8. When the second railing 5 rotates... The connecting rod 4 is rotatably connected to the second railing 5 and slidably connected to the connecting rod 4. When the second railing 5 is rotated to the opening angle, the connecting rod 4 is rotated to the end of the slide groove for a limit. When the first railing 3 and the second railing 5 are folded, they together form a combined railing. When the first railing 3 is opened, it is in a horizontal state. The second railing 5 can continue to open around the second end of the first railing 3 through the second rotating shaft 8, so that the second railing 5 is in a vertical state, thus forming an extended state. In the extended state, the first railing 3 forms an outwardly extending support platform, and the second railing 5 forms the outer railing of the support platform.

[0033] Reference Figure 4 As shown, the second rotating shaft 8 is equipped with a second fastener, which enables the second railing 5 to rotate or be fixed to the second end of the first railing 3. The second rotating shaft 8 is a cylindrical metal shaft, the diameter of which is designed according to the load-bearing requirements of the second railing 5, and the length of the second rotating shaft 8 must be greater than the connection thickness between the first railing 3 and the second railing 5. Both the first fastener 6 and the second fastener include a bolt and a nut, with the nut threaded onto the bolt. The first fastener 6 and the second fastener adopt a bolt-nut combination structure, which can form a bolt structure by opening external threads at the end of the second rotating shaft 8 without affecting rotation, and can be fixed and unlocked by changing the friction force by rotating the nut with a nut of a corresponding size. Correspondingly, the bolt is a hexagonal head bolt, which provides axial preload, and the nut is a hexagonal nut, which mates with the bolt thread. In some embodiments, an auxiliary washer is provided between the bolt head and the nut, and a flat washer or a spring washer is selected as the appropriate type.

[0034] Reference Figures 1-4 As shown, the plane of the second railing 5 can be perpendicular or parallel to the plane of the first railing 3. In edge protection, the second railing 5 unfolds into an edge railing of a horizontal support platform. The second railing 5 rotates to be perpendicular to the plane of the first railing 3, forming an L-shaped protective structure, which both forms a protruding support platform and blocks the risk of edge fall. When retracted, it is continuous with the main fixed railing 13, forming a continuous railing on the main platform.

[0035] Reference Figure 4As shown, it also includes fixed railings 13, which are respectively arranged on both sides of the first railing 3. When the protective platform is in the retracted state, the railing as a whole and the fixed railings 13 form a continuous plane, that is, when viewed from a top angle (not shown in the figure), the protective platform in the retracted state and the fixed railings 13 are continuous, forming a corridor, passageway or dock deck 1 railing.

[0036] Reference Figure 4 As shown, it also includes a support rod 11, one end of which is detachably installed on the second railing 5 and the other end is detachably installed on the fixed railing 13. Since the second railing 5 forms a platform at the second end of the first railing 3, and the first end of the first railing 3 is connected to the main deck 1, by setting support rods 11 on both sides of the first railing 3, protection is also formed on both sides of the first railing 3. Even when the first railing 3 serves as a support platform, its surrounding upper part is a semi-enclosed structure, leaving only a passage on the side connected to the main deck 1.

[0037] Reference Figure 4 , Figure 5 As shown, the second railing 5 and the fixed railing 13 are each equipped with multiple positioning posts 17 along their height direction when open. The support rod 11 has slots 12 at both ends that fit the positioning posts 17. The positioning posts 17 are evenly distributed along the vertical direction (height direction) of the second railing 5 and the fixed railing 13 when open, enabling flexible installation and quick disassembly of the support rod 11 at different heights.

[0038] Reference Figure 2 As shown, the first railing 3 includes a frame 302 and a support frame 301. The support frame 301 is fixedly installed inside the frame 302 and is a mesh support frame 301. When unfolded, the first railing 3 forms a horizontally extending support platform. Its mesh support frame 301 can directly serve as a standing surface for workers and can also be equipped with anti-slip protrusions to prevent slipping. When folded for storage, the hollow structure of the mesh support frame 301 reduces wind resistance and the impact of strong winds on the water surface, facilitating flipping operations.

[0039] Reference Figure 1 As shown, the support 2 has an arc-shaped groove 9, the center of which is the axis of the first rotating shaft 7. When it is necessary to adjust the angle of the first railing 3, first loosen the nut of the first fastener 6 to eliminate the clamping force between the bolt and the support 2. At this time, the first railing 3 can rotate freely around the first rotating shaft 7, causing the bolt to slide along the contour of the arc-shaped groove 9. When the first railing 3 rotates to a vertical position, the first rotating shaft 7 abuts against the inner wall of the end of the arc-shaped groove 9, and the arc-shaped groove 9 can also limit the movement of the first railing 3.

[0040] Reference Figure 3 , Figure 6As shown, the second railing 5 includes an extension 51 and a support 52. In the folded state, one end of the extension 51 is rotatably connected to the first railing 3, and its axis is inclined to the plane of the first railing 3. The support 52 is connected to the end of the extension 51, and its axis is parallel to the plane of the first railing 3. The extension 51 allows the main body of the second railing 5 to recline, and the support 52 constitutes the main body of the second railing 5. Each set of second railings 5 ​​consists of two railings, connected by a crossbar 10 to enhance the safety of the stop.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
