Description

Technical Field

[0001] The invention belongs to the technical field of boom equipment, in particular to a rotatable pneumatic hoist boom. Background Art

[0002] Pneumatic hoist boom is a type of lifting machine, mostly used on ships. It is generally used to lift lower objects to the deck of the ship. Compared with traditional manual handling or conventional booms, pneumatic hoist booms save time and effort.

[0003] When in use, the existing pneumatic hoist boom is generally fixed and can only hoist items to a designated location. It has poor flexibility and cannot allow items to pile up at the location where the items are placed. Once items pile up, there will be nowhere to put the items hanging on the equipment. The only way to proceed with subsequent operations is to wait until the items at the designated location are cleared. At the same time, because the existing pneumatic hoist boom has a relatively long force arm, the equipment will occupy a large space on the ship and will also block the path on the ship, making it inconvenient for the crew to work. Therefore, it needs to be improved. Summary of the invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a rotatable pneumatic hoist boom, which has the advantage of being able to rotate to place objects. The present invention is conducive to improving the overall flexibility of the equipment through the design of the rotating structure, which is convenient for users to use.

A second liquid inlet hole 26 is opened on the outer surface of the adjustment cylinder 19 near the bottom of the layered ring 24.

[0037] The provision of the layered ring 24 is conducive to conveniently layering the lubricating oil, so that the lubricating oil enters the top and bottom of the layered plate 30 through the first liquid inlet hole 25 and the second liquid inlet hole 26 respectively, so as to lubricate the parts inside the adjustment cylinder 19, which is conducive to increasing the service life of the equipment and improving the smoothness of equipment use.

[0038] As Figure 6As shown, one side of the adjusting rod 23 close to the front is connected to the adjusting cylinder 19 by bearings. A first helical gear 27 is fixedly connected to the outer side of the adjusting rod 23, and the first helical gear 27 is located inside the adjusting cylinder 19 near the back.

[0039] By providing the adjusting rod 23, it is beneficial to reduce the situation of hand slipping when the user uses the adjusting rod 23 through the opening of the anti-slip groove on the adjusting rod 23, which is beneficial to further improve the safety of equipment use and improve the overall stability.

[0040] As Figure 7 shown, a second helical gear 28 meshes with the top of the first helical gear 27, and a control limiting block 29 meshes with the second helical gear 28 near the front. A layered plate 30 is fixedly connected to the top of the control limiting block 29.

[0041] By providing the control limiting block 29, it is beneficial to limit the rotation of the second helical gear 28 to a certain extent, avoid excessive rotation of the second helical gear 28, resulting in a collision between the boom arm 8 and the ship's board, which is beneficial to improve the safety of equipment use and improve the user's experience.

[0042] As Figure 7 shown, a bearing block 31 is movably connected to the center of the top of the second helical gear 28, and the top of the bearing block 31 is movably connected to the bottom of the layered plate 30.

[0043] By providing the layered plate 30, it is beneficial to layer the parts inside the adjusting cylinder 19, avoid the situation of mutual interference up and down, and ensure the normal operation of the equipment and the stability of equipment operation.

[0044] As Figure 8 shown, a control gear 32 is fixedly connected to the center of the top of the layered plate 30. Adjusting gears 33 are meshed with the outside of the control gear 32 at equal angles. A third fixing rod 35 is fixedly connected to the top of the adjusting gear 33. A limiting plate 34 is movably sleeved on the outer surface of the third fixing rod 35 near the bottom. A bearing ring 36 is movably connected to the outer surface of the third fixing rod 35 near the top. The outer surface of the bearing ring 36 is fixedly connected to the bottom of the first structural steel pipe 1.

[0045] By providing the adjusting gears 33, it is beneficial to improve the accuracy of the adjustment angle, facilitate the user to obtain a more accurate rotation angle, and enable the user to place the item in a more accurate position when using.

[0046] As Figure 8As shown, one side of the first liquid inlet hole 25 close to the inner side of the adjustment cylinder 19 communicates with the top of the layered plate 30, and one side of the second liquid inlet hole 26 close to the inner side of the adjustment cylinder 19 communicates with the bottom of the layered plate 30. The ratio of the inner wall thickness of the adjustment cylinder 19 near the top to the inner wall thickness of the adjustment cylinder 19 near the bottom is two to one.

[0047] With the provision of the adjustment cylinder 19, it is beneficial to improve the overall sealing degree through the adjustment cylinder 19, avoiding the situation that the equipment is invaded by humid air. Through the design of different spaces at the top and bottom of the adjustment cylinder 19, more sufficient operating space is provided for the first helical gear 27 and the second helical gear 28.

[0048] The working principle and usage process of the present invention: When in use, the user must first weld the equipment at the required position through the square cushion plate 4, adjust the lifting rope led out from the rope outlet hole 7 through the pneumatic device inside the windproof cylinder 6, improve the smoothness of equipment use through the limit fixing plate 11 and the structural plate 13, and the limit cylinder 17 plays a role in limiting the lifting rope. At the same time, by the user shaking the adjustment rod 23, the sealing performance inside the sealing cover 22, the adjustment rod 23 and the adjustment cylinder 19 is adjusted. Then, the first helical gear 27 is driven by the adjustment rod 23, the first helical gear 27 drives the second helical gear 28 to rotate, the second helical gear 28 drives the control limiting block 29 to rotate, the layered plate 30 is driven to rotate by the control limiting block 29, the control gear 32 is driven to rotate by the layered plate 30, so as to drive the adjustment gear 33 to rotate as a whole. The adjustment gear 33 drives the limit plate 34 and the third fixing rod 35, the third fixing rod 35 drives the bearing ring 36 to rotate, and finally the first structural steel pipe 1 is driven to rotate by the bearing ring 36, so as to achieve the rotation effect. The rotation of the second helical gear 28 is limited by the control limiting block 29 to prevent the equipment from rotating excessively and hitting the ship's plate. During rotation, the lifting rope will be driven to swing, and the limit cylinder 17 can limit it to reduce the swing amplitude. Through the support sub-arm 18, the stability of the position of the limit cylinder 17 is ensured. With the provision of the smooth curved surface inside the limit cylinder 17, it is beneficial to reduce the influence brought by the friction generated by the lifting rope. By adding lubricating oil into the inner part of the oil inlet hole 21, the lubricating oil enters the first liquid inlet hole 25 and the second liquid inlet hole 26 respectively through the layered ring 24, and enters the top of the layered plate 30 and the top of the layered plate 30 through the first liquid inlet hole 25 and the second liquid inlet hole 26 to add lubricating oil conveniently, so as to ensure the smooth operation of the internal parts.
