Description

Technical Field

[0001] The invention belongs to the technical field of crane column structures, and in particular relates to a high-strength and high-stability ship crane column frame structure. Background Art

[0002] The column frame of a ship crane is an important part of the ship crane. It is generally divided into two parts: the tower and the column. It not only needs to bear the vertical load generated when lifting heavy objects, but also needs to cope with dynamic loads such as wind and wave impact in the offshore environment, especially when the wind is strong at sea. Therefore, designing a stable and efficient column frame structure is crucial to ensure the safe operation of the ship crane.

[0003] The existing Chinese patent document with publication number CN113104747B proposes an automatic counterweight tower crane that is windproof and anti-falling. By designing a windproof mechanism, an anti-falling structure and an automatic counterweight structure, the tower crane column and the wind turbine column are integrated to overcome the influence of wind on the tower crane. Although a windproof mechanism is designed, the wind force at sea is changeable. Strong winds or gusts may cause the interaction between the tower crane and the wind turbine to become complicated, and even cause resonance.

[0004] Therefore, the present invention proposes a high-strength and high-stability ship crane column frame structure to solve the problem in the prior art that a wind-proof mechanism designed on the outside of the column is prone to cause resonance in a gusty and strong wind environment. An integrated column structure is designed and equipped with a locking structure. The column structure can be locked in a gusty and strong wind environment to avoid resonance shaking.

DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 See also Figures 1 to 20 The present invention provides a technical solution: a high-strength and high-stability ship crane column frame structure, comprising a ship crane cross beam 1, a telescopic beam 11 is movably installed at the front end of the ship crane cross beam 1, a rotating column frame structure 3 is arranged below the ship crane cross beam 1, a crane column seat structure 2 is arranged below the rotating column frame structure 3, the crane column seat structure 2 includes a column seat 21, a main rotating shaft 22, a column support plate 24 and a movable locking block 25, the rotating column frame structure 3 includes a rotating plate 31, a column frame 32 and an auxiliary support frame 33, and a gyroscopic stabilizer is fixedly installed above the outer surface of the main rotating shaft 22. The fixed structure 221, the middle part of the lower surface of the rotating disk 31 is fixedly connected to the upper end of the main rotating shaft 22, the main rotating shaft 22 is rotatably mounted inside the column seat 21, and a gear driving structure 23 for driving the main rotating shaft 22 to rotate is arranged on one side of the column seat 21, the column frame 32 is fixedly mounted on the upper surface of the rotating disk 31, the auxiliary support frame 33 is fixedly mounted on both sides of the rotating shaft of the ship crane beam 1, the lower end rotating shaft of the ship crane beam 1 passes through the side wall of the auxiliary support frame 33 and is rotatably connected to the side wall of the column frame 32, and the outer surface of the auxiliary support frame 33 is symmetrically provided with a limiting groove 331 adapted to the column frame 32; In this embodiment, a telescopic rod is provided at the front end of the ship crane beam 1, which can extend or contract the telescopic beam 11, so as to facilitate lifting heavy objects. The bottom of the column seat 21 can be fixedly installed on the deck of the ship by welding or bolts, and is used to support the rotation of the main rotating shaft 22. The gear driving structure 23 can drive the main rotating shaft 22 to drive the rotating disk 31 to rotate as a whole. The rotating disk 31 supports the ship crane beam 1 through the column frame 32. A large telescopic rod for driving the ship crane beam 1 to rotate and lift is provided on one side of the rotating disk 31, and a control room is also provided on one side of the rotating disk 31. The auxiliary support frame 33 mainly plays an auxiliary reinforcement role on both sides of the ship crane beam 1, and can rotate with the ship crane beam 1 to strengthen the rotation of the ship crane beam 1 and the column frame 32. The strength of the connection, and the limiting groove 331 arranged above the auxiliary support frame 33 is adapted to the upper end of the column frame 32, which mainly plays a limiting role with the column frame 32 when the ship crane beam 1 rotates, and increases the stability of the ship crane beam 1 during rotation and lifting operations. The auxiliary support frame 33 also has a certain clamping effect on both sides of the ship crane beam 1. The gyroscopic stabilizing structure 221 on the outside of the main rotating shaft 22 increases the total angular momentum of the rotation of the main rotating shaft 22, and improves its ability to resist external disturbances, so that the overall rotating disk 31 rotates more stably, especially in the face of sudden impact or vibration, it can reduce tilting and shaking, help reduce tilting and shaking caused by wind, waves or other external factors, and provide a more stable operating environment for the ship crane beam 1 and the telescopic beam 11 as a whole.

[0021] Embodiment 2 See also Figures 1 to 20 On the basis of the first embodiment, the present embodiment further proposes that the outer surface of the gyro-like stable structure 221 is evenly distributed with stable wing plates 2211, the middle part of the outer surface of the gyro-like stable structure 221 is provided with a limited slide rail 2212, the inner part of the limited slide rail 2212 is provided with a locking groove 2213, the column support plate 24 is fixedly installed on the inner surface of the column seat 21, the upper surface of the column support plate 24 is evenly distributed with fixed limit blocks 241, the column support plate 24 and the movable locking blocks 25 are respectively provided with six groups, and the six groups of movable locking blocks 25 and fixed limit blocks 241 are distributed at intervals on the outer side of the gyro-like stable structure 221; In this embodiment, the column support plate 24 mainly serves to install the fixed limit block 241 and to limit the movable locking block 25. In normal working state, the column support plate 24 is consistent with the movable locking block 25 and is surrounded by the outside of the simulated gyroscope stabilizing structure 221. At this time, the external locking block 254 cooperates with the limit slide rail 2212 to limit the simulated gyroscope stabilizing structure 221 so that the simulated gyroscope stabilizing structure 221 can rotate normally with the main rotating shaft 22, but the movable locking block 25 and the column support plate 24 are not in direct contact with the simulated gyroscope stabilizing structure 221. Once an abnormal situation occurs, it can help the simulated gyroscope stabilizing structure 221 resist external forces that may cause overturning. For example, it can effectively prevent overturning accidents caused by the displacement of heavy objects or strong winds, thereby greatly improving operational safety.

[0022] Embodiment 3 See also Figures 1 to 20 On the basis of the second embodiment, the present embodiment further proposes that a telescopic rod 26 for driving the movable locking block 25 to slide is fixedly installed on the side wall of the column seat 21, an external locking block 254 is fixedly installed in the middle of the side surface of the movable locking block 25, and the external locking block 254 is adapted to the locking groove 2213. The inner side wall of the movable locking block 25 is symmetrically fixedly installed with an internal locking block 251, and the inner side wall of the movable locking block 25 is symmetrically and movably installed with an active squeezing tongue 252, and a telescopic elastic spring is movably installed between the side surface of the internal locking block 251 and the side surface of the active squeezing tongue 252. Spring rod 2511, a locking plug 2512 is movably installed inside the built-in locking block 251, a slot adapted to the locking plug 2512 is provided on the upper surface of the column support plate 24 and the lower surface of the rotating plate 31, a built-in stopper 253 is provided on one side of the built-in locking block 251, and the built-in stopper 253 is respectively fixedly installed on the surface of the column support plate 24 and the rotating plate 31, a push pin 2531 is movably installed inside the built-in stopper 253, and an oblique slot adapted to the push pin 2531 is provided on one side of the built-in locking block 251 close to the built-in stopper 253; In this embodiment, the telescopic rod 26 mainly drives the active locking block 25 to move inward at the same time, which is mainly used to force the active locking block 25 to move inward to lock the gyro-like stabilizing structure 221 as a whole when strong winds occur. The built-in stopper 253 is internally provided with an elastic plate to help the push pin 2531 to reset, and the built-in locking block 251 is internally provided with an elastic plate to help the locking plug 2512 to reset. It should be noted that in strong winds, the ship crane crossbeam 1 is in a non-working state and the telescopic beam 11 is in a telescopic locking state. At the same time, the rotating disk 31 also needs to be reset to the initial position in advance and be in a static state, that is, the external locking block 254 is in a state corresponding to the position of the gyro-like stabilizing structure 221. In this way, when strong winds come, At that time, the telescopic rod 26 works to drive the movable locking block 25 to move inward synchronously. At this time, the movable locking block 25, the internal locking block 251, and the movable squeezing tongue 252 move synchronously, and the external locking block 254 will be inserted into the locking groove 2213 to lock the gyro-like stabilizing structure 221, so that the gyro-like stabilizing structure 221, the main rotating shaft 22 and the entire rotating disk 31 are all in a fixed and static state, which increases the resistance to strong winds and increases the overall stability of the crane device. When the movable locking block 25 moves inward, the stabilizing wing plate 2211 on the surface of the gyro-like stabilizing structure 221 will resist the movable squeezing tongue 252. At this time, the movable squeezing tongue 252 will flip upward at a certain angle while sliding. The movable squeezing tongue 252 will squeeze the pushing pin 2531 inside the built-in stopper 253. At the same time, because the movable locking block 25 moves, the built-in locking block 251 will be close to the built-in stopper 253. At this time, the pushing pin 2531 is squeezed and moved backward, and will be inserted into the built-in locking block 251 to squeeze the locking plug 2512, so that the locking plug 2512 bulges. The upper locking plug 2512 will be inserted into the bottom of the rotating disk 31, and the lower locking plug 2512 will be inserted into the column support disk 24. In this way, the rotating disk 31, the column support disk 24, and the gyro-like stabilizing structure 221 will be in a mutually locked state, which increases the overall stability and avoids the possibility of overturning caused by strong winds. It is also very simple to release the lock. 26 pulls the movable locking block 25 to reset. At this time, the external locking block 254 is pulled out, the stabilizing wing plate 2211 is separated from the movable locking block 25, and the movable squeezing tongue 252 is reset under the action of the telescopic spring rod 2511, and the squeezing of the pushing pin 2531 is cancelled. The pushing pin 2531 is also reset. At the same time, the built-in locking block 251 leaves the built-in stopper 253, and the pushing pin 2531 is also pulled out and leaves the locking plug 2512. The locking plug 2512 retracts into the built-in locking block 251, and the rotating disk 31 and the column support disk 24 are no longer locked. At this time, the fixed limit block 241 and the movable locking block 25 resume the role of limiting the gyro-like stabilizing structure 221, and the gyro-like stabilizing structure 221 can rotate freely and stably with the main rotating shaft 22.

[0023] Embodiment 4 See also Figures 1 to 20 On the basis of the third embodiment, the present embodiment further proposes that a correction locking column structure 34 is fixedly installed in the middle of the inner surface of the auxiliary support frame 33, and a correction pin shaft 341 is threadedly connected inside the correction locking column structure 34. The correction pin shaft 341 penetrates the side walls of the auxiliary support frame 33 and the ship crane beam 1, and correction ball shafts 3411 are fixedly installed in the middle of both sides of the correction pin shaft 341. Buffer springs 343 adapted to the correction ball shaft 3411 are respectively arranged at both ends of the correction locking column structure 34, and feedback rings 342 are respectively fixedly installed on the outer surfaces of both sides of the correction locking column structure 34, and correction plug rods 3421 are movably installed inside the feedback ring 342. The correction plug rod 3421 penetrates the inner wall of the correction locking column structure 34, the position of the feedback circle 342 is adapted to the position of the correction ball shaft 3411, and the front end side wall of the auxiliary support frame 33 is symmetrically and movably installed with a telescopic beam locking pin 35, the outer surface of the telescopic beam locking pin 35 is threadedly connected to the inner wall of the ship crane beam 1, and the inner surface of the ship crane beam 1 is symmetrically and rotatably installed with a rotating locking frame 351, and the rear end of the telescopic beam 11 is fixedly installed with a telescopic beam locking block 36, one end of the telescopic beam locking pin 35 is clamped with the inner wall of one end of the rotating locking frame 351, and the side wall of the telescopic beam locking block 36 is provided with a locking hole adapted to the rotating locking frame 351; In this embodiment, the auxiliary support frame 33 not only increases the strength of the rotating connection of the ship crane beam 1, but also has a certain prompting effect on whether the rotating connection of the ship crane beam 1 is offset after a strong wind. Once the ship crane beam 1 vibrates and deviates due to strong wind interference, the correction locking column structure 34 on one side of the auxiliary support frame 33 is affected, the correction pin shaft 341 will be displaced, the correction ball shaft 3411 and the correction plug rod 3421 will be staggered, and the correction plug rod 3421 will shrink into the feedback circle 342. At this time, it serves as a prompt state, indicating that the ship crane beam 1 is in a stable state. The beam 1 is laterally offset, and then the correction pin 341 is rotated to adjust the correction ball shaft 3411 to move and reset, and the correction rod 3421 is pushed out again to correct the state of the ship crane beam 1. In addition, before the strong wind arrives, after the telescopic beam 11 is retracted, the telescopic beam locking pin 35 is rotated to pull one end of the rotating locking frame 351 backward. At this time, the rotating locking frame 351 rotates, and its front end is stuck in the telescopic beam locking block 36 at the rear end of the telescopic beam 11, which can enhance the locking stability of the telescopic beam 11 and the ship crane beam 1.

[0024] Embodiment 5 See also Figures 1 to 20 Based on the fourth embodiment, this embodiment further proposes a method for using a high-strength and high-stability ship crane column frame structure, comprising the following steps: Step 1: The bottom of the column seat 21 can be fixedly installed on the deck of the ship by welding or bolts to support the rotation of the main rotating shaft 22. During normal operation, the gear drive structure 23 can drive the main rotating shaft 22 to drive the rotating disk 31 to rotate as a whole. The large telescopic rod on one side of the rotating disk 31 can drive the ship crane beam 1 to rotate and lift. The telescopic rod at the front end of the ship crane beam 1 can make the telescopic beam 11 retractable, which is convenient for lifting heavy objects on the deck. It should be noted that the specific lifting process needs to be coordinated with the installation of cables, hooks, pulleys, cable retracting and unreeling rollers and other components, which will not be repeated here. Step 2: During normal operation, the column support plate 24 is consistent with the movable locking block 25 and surrounds the outer side of the gyro-like stabilizing structure 221. At this time, the external locking block 254 cooperates with the limiting slide rail 2212 to limit the gyro-like stabilizing structure 221 so that the gyro-like stabilizing structure 221 can rotate normally with the main body rotating shaft 22. Step 3: In a strong wind state, the ship crane cross beam 1 is in a non-working state and the telescopic beam 11 is in a telescopic locking state. At the same time, the rotating disk 31 also needs to be reset to the initial position in advance and is in a stationary state. The telescopic rod 26 drives the movable locking block 25 to move inward synchronously. At this time, the movable locking block 25, the built-in locking block 251, and the movable squeezing tongue 252 move synchronously, and the external locking block 254 will be inserted into the locking groove 2213 to lock the gyro-like stabilizing structure 221, so that the gyro-like stabilizing structure 221, the main rotating shaft 22 and the entire rotating disk 31 are all in a fixed and stationary state; Step 4, when releasing the lock, the telescopic rod 26 pulls the movable locking block 25 to reset, at this time the external locking block 254 is pulled out, the built-in locking block 251 and the built-in stopper 253 of the movable squeezing tongue 252 are all reset, and the rotating disk 31 and the column support disk 24 are no longer locked. At this time, the fixed limit block 241 and the movable locking block 25 resume the limiting effect on the gyro-like stabilizing structure 221, ensuring that the gyro-like stabilizing structure 221 can rotate freely and stably with the main rotating shaft 22.
