Description

Technical Field

[0001] The utility model relates to the technical field of marine static cone penetration testing. More specifically, the utility model relates to a marine static cone penetration suspension platform. Background Art

[0002] Static cone penetration testing is a technical means of uniformly pressing a probe equipped with sensors into the soil to obtain some basic physical and mechanical properties of the soil, and is widely used in offshore wind power, immersed tube tunnels, port terminals, reclamation projects, etc. Static cone penetration testing includes seabed type static cone penetration testing, downhole type static cone penetration testing, and platform type static cone penetration testing. The seabed type static cone penetration testing has high operation efficiency, low construction cost, can be penetrated at one time, is undisturbed, has accurate data, and is applicable to situations with relatively deep water depths. There are mainly two methods for lowering the seabed type static cone penetration testing main machine to the seabed surface: one is to lower it in the middle of the hull, which requires the ship itself to have a crescent pool. If not, it will require a considerable cost to modify the ship or purchase a new ship; such a ship has an opening in the middle position of the ship's deck, occupying a certain deck area and generally no longer having the conditions for carrying out other construction operations (such as vibroflotation construction, PVD construction, etc.); the other is to lower it on the side of the ship's hull, so that the ship's deck is not occupied and can be used for both static cone penetration testing and other construction operations. However, the distance from the seabed type static cone penetration testing main machine to the ship's hull exceeds 1 m, and it is very difficult and unsafe for construction workers to connect (or disassemble) the probe rods on the ship's deck. Therefore, it is urgent to develop a suspension platform to solve this problem. Summary of the Utility Model

[0003] An object of the utility model is to solve at least the above problems and provide at least the advantages described later.

[0004] To achieve these objects and other advantages of the present utility model, a marine static cone penetration suspension platform is provided, which is arranged on one side of the hull and includes:

[0005] A platform frame, which includes a plurality of longitudinals arranged in parallel. One end of each longitudinal is detachably arranged on the deck of the hull, and the other end extends out of the hull; a diagonal brace is arranged at the bottom of each longitudinal. One end of the diagonal brace is hinged to the end of the longitudinal extending out of the hull, and the other end is detachably connected to the side wall of the hull; a plurality of crossbeams are arranged between adjacent longitudinals;

[0006] A walkway board, which includes a plurality of panel units; the panel units are distributed on the platform frame;

[0007] A fence, which is arranged along the outer periphery of the part of the platform frame extending out of the hull.

[0008] Preferably, the length of the part of the longitudinal extending out of the hull does not exceed twice the length of its overlapping part with the deck.

[0009] Preferably, one or more sleeves are fixedly arranged on the deck of the hull corresponding to each of the longitudinal beams. At least one threaded hole is formed in the top of the sleeve, and a fastening screw rod is connected in the threaded hole.

[0010] Preferably, a sealing plate is fixedly arranged at one end of the diagonal brace connected to the hull. The sealing plate is arranged vertically, and a waist-shaped hole is formed therein; an ear plate is fixedly arranged on the side wall of the hull corresponding to each of the diagonal braces. The ear plate passes through the waist-shaped hole and is fixed by a screw rod and a nut.

[0011] Preferably, the panel unit includes at least two support rods arranged at intervals. The support rods span between two adjacent longitudinal beams or two adjacent cross beams and are detachably connected to the longitudinal beam or the cross beam; a plurality of panels are clamped on the two support rods.

[0012] Preferably, buckles are respectively arranged on the bottom surface of the panel corresponding to the two support rods.

[0013] The utility model at least has the following beneficial effects:

[0014] For the marine static cone penetration suspension platform provided by the utility model, one end of the platform frame extends out of one side of the hull to form a suspension platform, which is used as an operating platform for construction workers to connect or disassemble the sounding rods. The hoisting personnel lower the seabed type static cone penetration main machine to the seabed surface and adjust the position of the main machine so that the central hole of the sounding rod is located at the side edge of the suspension platform. The construction workers can connect or disassemble the sounding rods on the suspension platform, effectively solving the problem that it is very difficult and unsafe for the construction workers to connect or disassemble the sounding rods on the ship deck. While ensuring the construction safety, the construction efficiency of the static cone penetration operation can be improved; and the marine static cone penetration suspension platform has a simple structure, is easy to install and disassemble, and does not affect the structure of the hull itself.

[0020] The following further describes the present utility model in detail with reference to the accompanying drawings, so that those skilled in the art can implement it according to the text of the specification.

[0021] It should be noted that, unless otherwise specified, the experimental methods described in the following implementation schemes are all conventional methods, and the reagents and materials, unless otherwise specified, can all be obtained from commercial channels; in the description of the present utility model, the terms "horizontal", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0022] As Figures 1 to 4 shown, the present utility model provides a marine static cone penetration suspension platform, which is arranged on one side of the hull and includes:

[0023] A platform frame 2, which includes a plurality of longitudinals 21 arranged in parallel. One end of each longitudinal 21 is detachably arranged on the deck of the hull 1, and the other end extends out of the hull 1; a diagonal brace 4 is arranged at the bottom of each longitudinal 21. One end of the diagonal brace 4 is hinged to the end of the longitudinal 21 extending out of the hull 1, and the other end is detachably connected to the side wall of the hull 1; a plurality of crossbeams 22 are arranged between adjacent longitudinals 21;

[0024] A walkway board, which includes a plurality of panel units 6; the panel units 6 are distributed on the platform frame;

[0025] A fence 3, which is arranged along the outer periphery of the part of the platform frame 21 extending out of the hull 1.

[0026] In this technical solution, one end of the platform frame 2 extends out of one side of the hull 1 to form a suspension platform, which is used as an operating platform for construction workers to connect or disassemble the sounding rods. The hoisting personnel lower the seabed type static cone penetration main machine to the seabed surface and adjust the position of the main machine so that the central hole of the sounding rod is located at the side edge of the suspension platform. The construction workers can connect or disassemble the sounding rods on the suspension platform without bending down and stretching their bodies out of the outside of the platform to operate. The platform frame 2 is detachably connected to the deck of the hull 1 through one end thereof, and the diagonal brace 4 is arranged at the bottom to provide support. Figures 1 to 3A small platform frame with two of the longitudinal beams 21 is given as an example. In actual use, the number of the longitudinal beams 21 can be flexibly selected according to the survey requirements. To ensure operation safety, a fence 3 is arranged on the outer periphery of the overhanging part of the platform frame 2, and a walkway board is arranged. Preferably, the height of the fence 3 is not less than 1 m; the fences 3 on the two sides perpendicular to the hull include two grid-shaped fences 31 and a plurality of detachable cross bars 32 arranged between the two grid-shaped fences 31. The two grid-shaped fences 31 are fixedly connected to the platform frame 2, and the plurality of cross bars 32 are arranged at intervals in the height direction and can be temporarily disassembled according to the survey requirements. All structures in the overhanging platform are made of steel materials. The strength and stability of the platform frame 2 shall be checked by structural calculation to meet the load-bearing requirements of at least two construction operators, and the safety factor shall be greater than 2.

[0027] In another technical solution, to ensure the stability of the platform frame, the length of the part of the longitudinal beam 21 extending out of the hull 1 does not exceed twice the length of its overlapping part with the deck.

[0028] In another technical solution, the detachable connection between the longitudinal beam 21 and the deck is realized in the following way: one or more sleeves 11 are fixedly arranged on the deck of the hull 1 corresponding to each of the longitudinal beams 21. At least one threaded hole is opened at the top of the sleeve 11, and a fastening screw is connected in the threaded hole. When there is one sleeve 11, its length shall meet the force requirements of the platform frame 2. After one end of the longitudinal beam 21 passes through each of the sleeves 11 in sequence, the fastening screw at the top is tightened downward to fix the longitudinal beam 21. Preferably, the inner diameter of the sleeve 11 is slightly larger than the outer diameter of the longitudinal beam 21.

[0029] In another technical solution, a sealing plate 41 is fixedly arranged at one end of the diagonal brace 4 connected to the hull 1. The sealing plate 41 is arranged vertically, and a waist-shaped hole is opened thereon; a lug plate 5 is fixedly arranged on the side wall of the hull 1 corresponding to each of the diagonal braces. After the lug plate 5 passes through the waist-shaped hole, it is fixed by a screw and a nut. One end of the diagonal brace 4 is hinged to the longitudinal beam 21. The angle of the diagonal brace 4 is adjusted to enable the lug plate 5 to pass through the waist-shaped hole, and then one end of the screw is passed through the lug plate hole on the lug plate 5 and a nut is screwed on for fixation; different vertical hull side walls can be adapted through the waist-shaped hole.

[0030] In another technical solution, the panel unit 5 includes at least two support rods 51 arranged at intervals. The support rods 51 span across two adjacent longitudinal beams 21 or two adjacent cross beams 22 and are detachably connected to the longitudinal beam 21 or the cross beam 22, such as a mountain-shaped buckle or a conventional binding and fixing method; a plurality of panels 52 are clamped on the two support rods 51. Specifically, buckles are respectively arranged on the bottom surface of the panel 52 corresponding to the two support rods 21. The number of the panels 52 is flexibly selected according to the length of the support rod 51. The panel 52 can be a conventional pattern steel plate, and the buckle can be a commercially available pipe buckle. During construction, a support rod 51 with a suitable length is selected, the width between the two support rods 51 is controlled according to the size of the panel 52, and it is fixed to the platform frame 2, and then each panel 52 is sequentially buckled on it. The panel unit 5 can realize the rapid installation and disassembly of the walkway board and can be adapted to platform frames of different sizes.

[0031] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
