Description

Technical Field

[0001] The present invention relates to the technical field of safety nets, and particularly to a marine electric collapsible safety net. Background Art

[0002] Marine railings are safety devices to prevent personnel from falling outside the ship or onto the lower deck when the ship is swaying, and are generally installed on the open freeboard deck, superstructure deck and helicopter deck of the ship. In some special areas of the ship, there is a need for collapsible railings. For example, at the cargo hatch, when cargo lifting is required, the railing will hinder the lifting; when an emergency occurs and personnel need to escape, the railing at the assembly point also needs to be collapsed to ensure that personnel can evacuate from the ship at the fastest speed and ensure the safety of crew members and passengers.

[0003] Marine collapsible railings can currently be divided into two types technically: one is a manually collapsible railing, which is completely lifted manually, requires manual operation, is time-consuming and laborious, and has low efficiency; the other is a marine hydraulic collapsible railing, which uses hydraulic components with a high cost. The hydraulic system is exposed to the open air environment for a long time, and there is a risk of easy damage and oil leakage. Summary of the Invention

[0004] The present invention mainly solves the technical problems existing in the prior art, and thus provides a marine electric collapsible safety net that is simple and convenient to operate, and safe and reliable to use.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions:

[0006] The marine electric collapsible safety net provided by the present invention, the ship includes a deck and a structural ring beam of the apron. The structural ring beam of the apron is vertically arranged below the deck. The safety net includes:

[0007] An installation base plate, fixed to the middle of one side of the structural ring beam of the apron;

[0008] A main support, fixed to the installation base plate, and a motor is fixed in the middle of the main support;

[0009] A safety net body, the two ends of the bottom are respectively connected to the two ends of a connecting shaft through a connecting frame, and the top of the safety net body extends above the deck;

[0010] A connecting shaft, the middle of which is connected to the output shaft of the motor;

[0011] The limit position positioning plate is fixedly connected to the connecting shaft. The limit position positioning plate is provided with a first limiting surface and a second limiting surface, and an arc transition surface is arranged between the first limiting surface and the second limiting surface. When the motor rotates forward until the safety net body is vertical, the first limiting surface abuts against the main bracket. When the motor rotates reversely until the safety net body is laid down, the second limiting surface abuts against the main bracket.

[0012] Further, the safety net body includes an aluminum alloy handrail, an aluminum alloy plate mesh, and aluminum alloy square tubes. The aluminum alloy handrail is arranged on the top of the aluminum alloy plate mesh, and the aluminum alloy square tubes are enclosed and installed on the left and right sides and the bottom of the aluminum alloy plate mesh.

[0013] Further, both ends of the main bracket are connected to the connecting shaft through bracket bearings.

[0014] Further, the surface of the installation base plate is provided with a galvanized layer.

[0015] The beneficial effects of the present invention are as follows: By the forward and reverse rotation of the motor, the vertical and laying down of the safety net body can be directly controlled. The operation is simple and convenient, reducing the labor intensity and labor cost, and improving the work efficiency. Moreover, by arranging the limit position positioning plate on the connecting shaft and utilizing the mutual cooperation between the first limiting surface and the second limiting surface of the limit position positioning plate and the main bracket, the stability of the state of the safety net body when it is vertical and laid down is ensured, improving the safety and reliability of use. At the same time, the safety net body is installed on the structural ring beam of the apron under the deck through the main bracket and the installation base plate, which can avoid the safety net body from pulling and damaging the deck and destroying the strength and integrity of the deck when being deformed by external forces, thereby further improving the safety of use.

The limit position positioning plate 9 is provided with a first limiting surface 91 and a second limiting surface 93. An arc transition surface 92 is provided between the first limiting surface 91 and the second limiting surface 93. When the motor 5 rotates forward until the safety net body 6 is vertical, the first limiting surface 91 abuts against the main support 4. When the motor 5 rotates reversely until the safety net body 6 is laid down, the second limiting surface 93 abuts against the main support 4.

At the same time, the safety net body 6 is installed on the apron structural ring beam 2 under the deck 1 through the main support 4 and the installation bottom plate 3, which can avoid the safety net body 6 from pulling and damaging the deck 1 when being deformed by external forces, destroying the strength and integrity of the deck 1, thereby further improving the safety of use.

[0029] Specifically, the safety net body 6 includes an aluminum alloy handrail 61, an aluminum alloy plate mesh 62 and an aluminum alloy square tube 63. The aluminum alloy handrail 61 is arranged on the top of the aluminum alloy plate mesh 62, and the aluminum alloy square tube 63 is installed on the left and right sides and the bottom of the aluminum alloy plate mesh 62. Preferably, in order to ensure the stability of the safety net body 6 during the vertical and downfall process, the two ends of the main bracket 4 are connected to the connecting shaft 8 through the bracket bearing 10. Preferably, the bearing used in the bracket bearing 10 is an oil-free graphite bearing. Preferably, in order to improve the corrosion resistance, the surface of the mounting base plate 3 is provided with a galvanized layer.

[0030] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
