Description

Technical Field

[0001] This utility model relates to offshore caisson platforms, and in particular to an embedded manhole cover for offshore caisson platforms. Background Technology

[0002] The construction of the caisson is a crucial step in the entire building structure construction process, directly affecting the overall quality of the structure. During caisson construction, angle steel and partitions are often welded inside, playing a vital role in strengthening the caisson's strength and stability. After the welding inside the caisson is completed, the supervisor needs to inspect the welding condition. Manholes are pre-reserved or cut on-site by workers to facilitate welding work inside the caisson. Workers and supervisors use manholes to enter the caisson for welding and inspection, and also to lower guide pipes during subsequent concrete pouring. The manholes need to be sealed after construction. Since a large number of manholes need to be reserved throughout the construction process, sealing them all at once would result in a massive workload and tight on-site construction schedules. Therefore, an easy-to-operate method for opening and closing the manholes is required.

[0003] Currently, the most common methods for manhole covers are either directly covering the manhole with a single slab or using a specialized manhole structure. However, due to the large number of manholes, using a specialized manhole structure can increase the budget, and the limited construction site makes it impossible to configure a large number of manhole structures at once. Directly covering the manhole with a single slab requires multiple people to lift it when opening, which wastes both manpower and steel plate resources. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide an embedded manhole cover for an offshore caisson platform, which saves resources.

[0005] To solve the above-mentioned technical problems, this utility model provides an embedded manhole cover for an offshore caisson platform, comprising: a manhole plate and a cover plate; the manhole plate is cut with a manhole, and the cover plate includes a plate body, which is the plate body left when the manhole is cut on the manhole plate;

[0006] The plate is rotatably connected to the edge of the manhole via a hinge, so that the plate has an open position and a closed position relative to the manhole plate. When the plate is in the closed position, the plate is embedded in the manhole.

[0007] Supporting steel plates are provided on both sides of the upper surface of the plate along the width direction; at least two supporting steel plates are provided at intervals on the same side along the length direction of the plate; a portion of the supporting steel plate protrudes outward from the plate so that when the plate is in the closed position, the supporting steel plate abuts against the manhole plate to limit the fit along the direction of the plate from the open position to the closed position.

[0008] An operating component is provided on the upper surface of the plate, and the operating component is located on the side of the upper surface of the plate away from the hinge;

[0009] The hinge includes a first connecting plate and a second connecting plate, and a pivot shaft rotatably connected between the first connecting plate and the second connecting plate; the first connecting plate is fixedly connected to the cover plate, and the second connecting plate is fixedly connected to the manhole plate.

[0010] In a preferred embodiment: the operating element is an opening for a person to insert a hand.

[0011] In a preferred embodiment: the manhole is elliptical.

[0012] In a preferred embodiment: the rotating shaft is a damped rotating shaft.

[0013] In a preferred embodiment: another portion of the supporting steel plate is welded and fixed to the upper surface of the plate.

[0014] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0015] This utility model provides an embedded manhole cover for an offshore caisson platform. It is easy to operate and uses a cut steel plate as a manhole cover, saving labor and materials. Attached Figure Description

[0018] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0019] refer to Figures 1-2This embodiment provides an embedded manhole cover for an offshore caisson platform, comprising: a manhole plate 1 and a cover plate 2; the manhole plate 1 is cut with a manhole, and the cover plate 2 includes a plate body 21, which is the plate body 21 left when the manhole is cut on the manhole plate 1;

[0020] The plate 21 is rotatably connected to the edge of the manhole via a hinge 22, so that the plate 21 has an open position and a closed position relative to the manhole plate 1. When the plate 21 is in the closed position, the plate 21 is embedded in the manhole.

[0021] Supporting steel plates 23 are provided on both sides of the upper surface of the plate 21 along the width direction; at least two supporting steel plates 23 are provided at intervals on the same side along the length direction of the plate 21; a portion of the supporting steel plate 23 protrudes outward from the plate 21, so that when the plate 21 is in the closed position, the supporting steel plate 23 abuts against the manhole plate 1, so as to limit the fit along the direction of the plate 21 from the open position to the closed position;

[0022] An operating element is provided on the upper surface of the plate 21, and the operating element is located on the side of the upper surface of the plate 21 away from the hinge 22;

[0023] The hinge 22 includes a first connecting plate and a second connecting plate, and a rotating shaft rotatably connected between the first connecting plate and the second connecting plate; the first connecting plate is fixedly connected to the cover plate 2, and the second connecting plate is fixedly connected to the manhole plate 1.

[0024] In this embodiment, the operating element is an opening for a person to insert their hand, allowing the user to easily open and close the cover 2. The manhole is elliptical, facilitating entry and exit while minimizing the opening area. Furthermore, the rotating shaft is a damped rotating shaft, preventing the cover 2 from suddenly falling from the open position to the closed position.

[0025] Finally, in order to secure the supporting steel plate 23, another part of the supporting steel plate 23 is welded and fixed to the upper surface of the plate body 21.

[0026] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto.
