Description

Technical Field

[0001] The invention belongs to the technical field of ship manhole compartments, and relates to a mobile auxiliary device and a manhole structure for lightweight manhole maintenance of a large container ship. Background Art

[0002] For general large container ships, a pipe passage will be set up in the middle of the double bottom of the ship to facilitate electrical wiring and pipeline layout.

[0003] At present, when people need to maintain or repair pipelines, two methods are generally used. The first method is that workers walk to the destination in the pipe channel to maintain the pipeline. However, the pipe channel is small, and workers can only bend down and step forward, which is not easy to walk, which will consume a lot of time and effort. Workers cannot repair the pipeline in time, resulting in low work efficiency; the second method is to let the workers lie on the mobile cart in the pipe channel, and then push the internal structure of the pipe channel with their hands, so that the cart moves through the reaction force, so that the workers can move to the destination to maintain the pipeline. This method will also consume a lot of physical strength of the workers, and the existing carts are small in size and have no protective devices on both sides. During the movement of the cart, workers are prone to fall from the cart, which is less safe. After the cart reaches the destination, it may continue to move due to inertia, causing the workers to continue to retreat to the destination, which is more troublesome. Workers can also grab the internal structure of the pipe channel with their hands to brake the cart, but this braking method is easy to cause damage to the workers' hands. Summary of the invention

[0004] The present invention provides a mobile assistant and a pipe channel structure for lightweight pipe channel maintenance of a large container ship, which can overcome the shortcomings of the existing mobile trolley inside the pipe channel being small in size and having no protective devices on both sides, making it easy for workers to fall from the trolley and requiring workers to brake manually, which can easily cause injuries to the workers' hands.

The guide rails 2 are welded symmetrically on the bottom of the tunnel body 1.

[0036] Example 2

[0037] A mobile auxiliary device and pipe for maintenance of lightweight pipes and pipes for large container ships, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it includes a moving trolley 3, a mounting shell 41, a rotating rod 42, a safety belt 43, a buckle 44, a reset torsion spring 45, a protection mechanism 5 and a brake mechanism 6. The moving trolley 3 can move on the guide rail 2, and the worker can lie on the moving trolley 3, and the moving trolley 3 drives the worker to move to the destination to maintain the pipeline. The moving trolley 3 is connected to the mounting shell 41 and the buckle 44. The mounting shell 41 is rotatably connected with the rotating rod 42, and the rotating rod 42 is wrapped with a safety belt 43. The end of the safety belt 43 slides through the mounting shell 41, and the end of the safety belt 43 can be clamped in the buckle 44. The end of the safety belt 43 is fixed by the buckle 44, so that the safety belt 43 can be tied to the waist of the worker, thereby protecting the worker and preventing the worker from falling. A reset torsion spring 45 is connected between the rotating rod 42 and the mounting shell 41, and the moving trolley 3 is provided with a protection mechanism 5 and a brake mechanism 6.

[0038] like Figure 1 and Figure 3 As shown, the mobile vehicle 3 is composed of a support frame 31, auxiliary wheels 32, a dual-axis motor 33 and a driving wheel 34. The mounting shell 41 and the buckle 44 are respectively mounted on the left and right sides of the top of the support frame 31. The auxiliary wheels 32 are symmetrically rotatably connected to the lower rear side of the support frame 31. The dual-axis motor 33 is connected to the front side of the lower part of the support frame 31. The output shafts on both sides of the dual-axis motor 33 are connected to the driving wheel 34 through a coupling. Both the auxiliary wheels 32 and the driving wheel 34 can roll on the guide rail 2.

[0039] like Figure 1 , Figure 5 and Figure 6As shown, the protection mechanism 5 includes a protective plate 51, a connecting plate 52, a mounting rod 53, an electric push rod 54 and a control switch 55. The left and right sides of the support frame 31 are rotatably connected with the protective plates 51. The protective plates 51 rotate toward the side close to each other to block the left and right sides of the workers to prevent the workers from falling. The lower front part of the protective plate 51 is welded with a connecting plate 52, the lower front part of the support frame 31 is connected with two mounting rods 53, the front ends of the mounting rods 53 are rotatably connected with the electric push rods 54, the telescopic rods of the electric push rods 54 are rotatably connected to the adjacent connecting plates 52, the control switch 55 is installed on the top of the mounting shell 41, and the electric push rods 54 are electrically connected to the control switch 55.

[0040] like Figure 1 , Figure 7 and Figure 8 As shown, the brake mechanism 6 includes a connecting rod 61, a sliding rod 62, a return spring 63, a sliding block 64, a friction block 65, a connecting rod 66 and a contact rod 67. A connecting rod 61 is welded to the rear side of the bottom of the support frame 31. The sliding rod 62 is slidably connected to the rear end of the connecting rod 61. A return spring 63 is connected between the sliding rod 62 and the connecting rod 61. The sliding block 64 is symmetrically slidably connected to the rear side of the lower part of the support frame 31. The sliding block 64 is located on the inner side of the auxiliary wheel 32. The lower part of the side of the auxiliary wheels 32 that are away from each other is connected to the friction block 65. The friction block 65 moves toward the side away from each other and contacts with the guide rail 2, so that the moving trolley 3 can be stopped by friction. No manual brake is required, and the moving trolley 3 can be prevented from continuing to move under the action of inertia. The sliding block 64 and the sliding rod 62 are rotatably connected with a connecting rod 66. The top of the sliding rod 62 is connected to the contact rod 67, and the protective plate 51 rotates to contact the contact rod 67.

[0041] Initially, the guard plate 51 is in an open state, the guard plate 51 presses the contact rod 67, the reset spring 63 is in a compressed state, and the friction blocks 65 are in contact with the guide rail 2. Under the action of friction, the position of the mobile trolley 3 can be stabilized, which is convenient for the worker to lie on the top of the support frame 31. Then the right end of the safety belt 43 is pulled out to the right and inserted into the buckle 44. The safety belt 43 can drive the rotating rod 42 to rotate, the reset torsion spring 45 is deformed, and the buckle 44 can clamp the right end of the safety belt 43, so that the safety belt 43 is tied around the waist of the worker, thereby The control switch 55 is then pressed once to control the electric push rod 54 to drive the connecting plate 52 to swing away from each other, thereby driving the protective plate 51 to rotate toward the side close to each other. The protective plate 51 can block the left and right sides of the worker, thereby protecting the worker and preventing the worker from falling. At the same time, the protective plate 51 will release the contact rod 67, and the reset spring 63 will return to its original state, driving the sliding rod 62 and the contact rod 67 to move upward, and the sliding rod 62 can drive the sliding block 64 to move toward each other through the connecting rod 66. The two-axis motor 33 is driven to slide on one side, thereby driving the friction block 65 to move toward the side close to each other, so that the friction block 65 is separated from the guide rail 2, and then the double-axis motor 33 is started to drive the driving wheel 34 to rotate, so that the driving wheel 34 and the auxiliary wheel 32 can both roll on the guide rail 2, so that the worker can be driven to move through the support frame 31. When the worker reaches the destination, the double-axis motor 33 can be turned off to stop the auxiliary wheel 32 and the driving wheel 34 from rotating. At the same time, the control switch 55 can be pressed once to control the electric push rod 54 to drive the connecting plate 52 to move toward the side close to each other. One side swings, thereby driving the protective plate 51 to rotate and open to the side away from each other, the protective plate 51 will squeeze the sliding rod 62 and the contact rod 67 to move downward, the reset spring 63 is compressed, and the sliding rod 62 can drive the sliding block 64 to slide to the side away from each other through the connecting rod 66, thereby driving the friction block 65 to move to the side away from each other and contact the guide rail 2, under the action of friction, the moving trolley 3 can stop moving, preventing the moving trolley 3 from continuing to move under the action of inertia, at this time The worker can maintain or repair the pipeline.

[0042] Example 3

[0043] On the basis of Example 2, Fig. 9As shown, it also includes a sliding baffle 71, a guide rod 72, a fixing frame 73 and a compression spring 74. Two sliding baffles 71 are slidably connected to the rear side of the upper part of the support frame 31. Pull rings are welded on the tops of the sliding baffles 71. Two guide rods 72 are symmetrically welded in the support frame 31. The guide rods 72 are both located below the sliding baffles 71. A fixing frame 73 is slidably connected between the two guide rods 72. Maintenance tools can be stored in the support frame 31. The maintenance tools are pressed by the fixing frame 73, which can facilitate workers to carry and take maintenance tools. Compression springs 74 are wound around the two guide rods 72. The two ends of the compression spring 74 are respectively connected to the support frame 31 and the fixing frame 73. When workers need to carry maintenance tools, When repairing tools, the front sliding baffle 71 can be pulled forward and opened through the pull ring, and then the repair tools can be placed in the support frame 31. As the number of repair tools increases, the repair tools will squeeze the fixing frame 73 to move forward, and the compression spring 74 will be compressed. Under the elastic force of the compression spring 74, the fixing frame 73 can fix the position of the repair tools, and then the front sliding baffle 71 can be pulled backward and closed. When it is necessary to take out the repair tools, the rear sliding baffle 71 can be pulled backward and opened through the pull ring, and then the repair tools can be taken out. The compression spring 74 slightly returns to its original state, driving the fixing frame 73 to move backward, which can push the remaining repair tools backward, making it convenient for workers to take them out.

[0044] like Figure 1 and Fig.10 As shown, a prompt component 8 is also included, which includes a universal rod 81 and a laser emitter 82. A plurality of universal rods 81 are connected at intervals at the top of the pipe body 1, and the laser emitters 82 are installed at the lower ends of the universal rods 81. Workers can adjust the direction and angle of the universal rods 81 according to the internal structure of the pipe body 1 so that the laser emitter 82 can emit lasers toward some protruding parts. When workers find that a part of their body blocks the laser during movement, it means that they may hit the protruding parts inside the pipe body 1. At this time, the workers can adjust their body position to prevent injuries, which serves as a prompt.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
