Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, and particularly relates to an auxiliary device for ship electrical equipment to enter the cabin. Background Technique

[0002] During the ship manufacturing process, the installation and connection of ship electrical equipment need to be carried out in the equipment cabin. These equipment include generators, switchboards, cables, control equipment, etc. They are the core components of the ship electrical system, directly related to the normal operation of ship power, lighting, communication, navigation, etc. And ship electrical equipment needs to be maintained and overhauled regularly to ensure its long-term stable operation. In the equipment cabin, it can provide necessary working conditions for operators, making the maintenance and overhaul work more convenient, fast and effective. Therefore, during the ship manufacturing process, ship electrical equipment needs to enter the cabin to ensure the normal installation, commissioning, testing, maintenance and overhaul of the equipment, and maximize the reliability and safety of the equipment.

[0003] After investigation, a Chinese utility model patent discloses a device for ship equipment to enter the cabin (publication number: CN216994761U), which includes a base, a lifting device, a carrying frame, a pair of moving tracks, a moving platform and a limiting component. The lifting device is installed on the base. The carrying frame is installed on the lifting device, and the carrying frame is configured with a carrying surface; the lifting device is used to raise or lower the carrying frame to a predetermined height so that the carrying surface is flush with the deck plane of the ship cabin. A pair of moving tracks are installed in parallel on the carrying surface. The bottom side of the moving platform is provided with rollers, and the rollers are used to cooperate with the moving tracks, and the rollers can slide along the moving tracks. The upper side surface of the moving platform is used to carry ship equipment. The limiting component is arranged on the moving tracks and is used to limit the sliding of the rollers on the moving tracks.

[0004] Although the above patent can enable the equipment to enter the cabin horizontally from the side of the ship cabin without opening a detachable plate at the top of the cabin, effectively increasing the stability of the hull structure and improving safety, but after the above device lifts the equipment to the required height, it pushes the moving platform along the moving track to move to the cabin. Generally, there is a threshold in the ship cabin. Affected by the objective factor of the cabin threshold obstruction, generally, the ship electrical equipment is transported across the threshold into and out of the cabin by manual lifting. During the manual lifting process, it is also necessary to avoid the ship electrical equipment bumping against the two side cabin walls and the cabin door, which is time-consuming and laborious and has certain safety hazards.

[0005] Therefore, the utility model provides an auxiliary device for ship electrical equipment to enter the cabin to solve the above problems. Content of the Utility Model

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides an auxiliary device for a ship electrical equipment to enter the cabin, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. The auxiliary device includes a mounting frame 1 for placing the equipment, a support plate 11 arranged below the mounting frame 1, a lifting device 2 arranged between the mounting frame 1 and the support plate 11 for lifting the mounting frame 1, a first roller 13 arranged below the support plate 11 for moving, and a lifting mechanism 3 arranged on both sides of the mounting frame 1 for supporting the mounting frame 1.

[0029] The lifting mechanism 3 includes a plurality of support legs 31 all fixedly installed on the mounting frame 1, telescopic legs 32 slidably installed inside the support legs 31 for extending the support legs 31, second rollers 33 arranged at one end of the telescopic legs 32 away from the support legs 31, accommodation parts opened inside the support legs 31 for the telescopic legs 32 to slide, a connecting pipe 36 fixedly installed on the support legs 31 for connecting a plurality of accommodation parts, and an air pump 38 fixedly installed on the mounting frame 1 for pressurizing the accommodation parts.

[0030] A pressure relief mechanism 4 for discharging the gas in the accommodation part is arranged on the support leg 31.

[0031] The lifting device 2 is an existing technology well-known to those skilled in the art, preferably a forklift. Its working principle will not be elaborated here. The air pump 38 is a common supercharging air pump in the existing technology, and its specific model can be selected according to the actual situation. The ship electrical equipment is installed on the installation frame 1. When using the installation frame 1 to carry the ship electrical equipment in and out of the cabin, the support plate 11 supports the installation frame 1, the support leg 31 and the ship electrical equipment, and transports the ship electrical equipment to the threshold. At this time, the support leg 31 at one end of the installation frame 1 enters the threshold. Start the air pump 38 to pressurize the connecting pipe 36, and then make the high-pressure gas fill into the accommodating part. The high-pressure gas presses against the telescopic leg 32, so that the telescopic leg 32 extends out of the support leg 31. After the second roller 33 touches the ground, continue to pressurize to make the telescopic leg 32 continue to extend. Thus, with the cooperation of the telescopic leg 32 and the support leg 31, support the installation frame 1, the support plate 11 and the ship electrical equipment. Turn off the air pump 38. When using the lifting device 2 to contract the support plate 11, make the support plate 11 contract towards the installation frame 1, and be in a state where it can cross the threshold. After both the support plate 11 and the first roller 13 pass through the threshold, use the lifting device 2 to drive the support plate 11 and the first roller 13 to contact the ground, so that the support leg 31 and the telescopic leg 32 leave the ground, and then make the other end of the installation frame 1 enter the threshold, completing the process of the ship electrical equipment entering the cabin.

[0032] Further, in order to facilitate contracting the telescopic leg 32 into the support leg 31, as Figure 3 , Figure 4 and Figure 6 shown, the pressure relief mechanism 4 includes a fixed pipe 41 fixedly installed on the support leg 31 and communicated with the accommodating part, a fixed ring 42 fixedly installed in the fixed pipe 41, a rubber plug 43 slidably installed in the fixed pipe 41 for plugging the opening of the fixed ring 42, an installation rod 44 fixedly installed on the rubber plug 43 for driving the rubber plug 43 to move closer to or away from the fixed ring 42, a top pressure spring 45 sleeved on the installation rod 44 for making the rubber plug 43 move closer to the fixed ring 42, and an air hole 46 opened at one end of the fixed pipe 41 away from the fixed ring 42.

[0033] When it is necessary to contract the telescopic leg 32 into the support leg 31, pull the installation rod 44 to make the rubber plug 43 slide in the direction away from the fixed ring 42, and the rubber plug 43 is separated from the fixed ring 42, so that the high-pressure air in the accommodating part enters the inside of the fixed pipe 41 and leaks out from the air hole 46. When the high-pressure gas in the accommodating part is released, the telescopic leg 32 is contracted inside the support leg 31 by the gravity of the ship electrical equipment itself. After the high-pressure gas in the accommodating part is released, release the installation rod 44. The installation rod 44 pushes the rubber plug 43 to reset under the action of the top pressure spring 45, plugs the fixed ring 42, and keeps the inner cavity of the accommodating part airtight for the next use.

[0034] Furthermore, in order to increase the speed at which the telescopic leg 32 retracts into the support leg 31, as Figure 5 shown, the lifting mechanism 3 further includes a fixing rod 34 fixedly installed on the telescopic leg 32 and slidably connected to the support leg 31, and a return spring 37 sleeved on the fixing rod 34 for moving the fixing rod 34 closer to the support leg 31.

[0035] When the telescopic leg 32 extends out from the inside of the support leg 31, the telescopic leg 32 pulls the fixing rod 34 to slide synchronously, and at the same time the return spring 37 is compressed. When the high-pressure gas inside the accommodating part is released from the inside of the fixing tube 41, the return spring 37 releases its elastic potential energy, pushes the fixing rod 34 to reset, and then drives the telescopic leg 32 to retract into the support leg 31, accelerating the retraction speed of the telescopic leg 32 and facilitating use.

[0036] In order to improve the sealing performance of the accommodating part, as Figure 5 shown, the lifting mechanism 3 further includes a gasket 35 provided on the telescopic leg 32 for sealing the accommodating part.

[0037] When the high-pressure gas is filled into the accommodating part, the gasket 35 improves the connection sealing performance between the telescopic leg 32 and the support leg 31, making it difficult for the high-pressure gas to leak from the accommodating part and facilitating use.

[0038] In order to facilitate the use of the rubber plug 43 to block the fixing ring 42, as Figure 6 shown, the rubber plug 43 is arranged in a conical shape, and the opening of the fixing ring 42 contacts the outer wall of the rubber plug 43.

[0039] When the rubber plug 43 blocks the fixing ring 42, the rubber plug 43 is pushed by the top pressure spring 45, so that the rubber plug 43 has a tendency to slide towards the fixing ring 42 in real time, making it even more difficult for the high-pressure gas in the accommodating part to leak.

[0040] In order to provide an installation space for the support plate 11, a telescopic rod 12 is fixedly connected to the support plate 11, and the movable end of the telescopic rod 12 is fixedly connected to the installation frame 1.

[0041] When the distance between the support plate 11 and the installation frame 1 changes, the telescopic rod 12 can easily change its length according to the actual use situation, providing guidance for the lifting of the support plate 11.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
