[0002] In ship transportation and offshore construction, super-heavy single-pipe piles are important structural components and are often used in the foundation construction of offshore platforms and the installation of other marine projects. Due to their large size and huge weight, single-pipe piles are usually transported using roll-on / roll-off equipment.

[0003] After searching, the invention patent with application number CN111391979A discloses a thousand-ton lifting roll-on / roll-off equipment, which is basically described as: comprising a lifting roll-on / roll-off device, the lifting roll-on / roll-off device comprising a lifting beam and a gantry beam symmetrically arranged at both ends of the lifting beam, the lifting beam is used to support the wind power tower, the gantry beam is connected to the lifting beam through a lifting system, and a walking wheel group is arranged at the lower end of the gantry beam. The invention can meet the height difference between different tide levels and the dock surface, reduce the depth requirements for transport ships, reduce transportation costs, reduce the risk of instantaneous ship deck sinking during bridge roll-on / roll-off, and has higher safety and stability.

[0004] However, in practice, the device mainly adjusts its height through a lifting system to adapt to the tide level and dock height difference, but does not provide track cleaning or obstacle removal functions.

[0016] The present invention provides a ship-based super-heavy-duty single-pipe pile rolling and rolling device with high space utilization.

The design is compact to improve the space utilization. When the super-heavy single-pipe pile body is placed in place, the lifting and clamping device is operated to gradually descend, and the super-heavy single-pipe pile body is clamped inside the lifting and clamping device. Then the operator can start the rolling and rolling device body to move on the track. When the rolling and rolling device body moves, the extrusion spring squeezes the push plate, so that the push plate drives the limit plate to descend. The descent of the limit plate can make the cleaning brush 1, the cleaning brush 2 and the cleaning brush fit the track, remove the debris around the track, and keep the track clean, thereby reducing the rolling resistance and ensuring the smooth operation of the rolling and rolling device body. If there are large-mass debris on the track, the descent of the limit plate will be blocked, thereby pushing the two rubber plates. The movement of the rubber plate will drive the sleeve to slide forward, thereby pushing the trigger rod to compress the two push-type power switches. At this time, the push-type power switch is triggered, and the movement of the roll-on / roll-off device body is automatically stopped. The operator can quickly detect the presence of obstacles and promptly remove foreign objects around the track to ensure the continued normal operation of the roll-on / roll-off device body. In addition, the detection mechanism plays an important role in the operation of the device. Whenever the roll-on / roll-off device body moves along the track, the balls embedded in the track will slide against the inner wall of the track. If the track is deformed or an obstacle appears to block it, the balls will be squeezed by the track or the obstacle, thereby pushing the installation arc plate to move. This displacement will drive the extension plate to squeeze the trigger end, and the trigger end will further activate the alarm. Once the alarm is activated, the operator will be immediately reminded and quickly take measures to remove obstacles or perform maintenance to ensure the safe operation of the roll-on / roll-off device body.

The inner walls of the two mounting cylinders 218 are fixedly connected with abutment plates 216. The middle parts of the two abutment plates 216 are slidably connected with trigger rods 215. The outer walls of the two mounting cylinders 218 are slidably connected with sleeves 209. The interiors of the two sleeves 209 are provided with return springs 214. One ends of the two return springs 214 are respectively fixedly connected to the inner walls of the sleeves 209. The other ends of the two return springs 214 are respectively fixedly connected to the inner sides of the two abutment plates 216. One ends of the two trigger rods 215 are respectively fixedly connected to the inner walls of the two sleeves 209. One ends of the two sleeves 209 are fixedly connected with rubber plates 213. The outer sides of the two rubber plates 213 are both fitted to the inner sides of the limit plates 203.The bottom ends of the two rolling device bodies 4 are slidably connected to the top ends of the two rails 1. It should be noted that the lifting and clamping device 5 is composed of a lifting platform and two clamping arms. This design uses existing technical solutions to achieve accurate clamping and lifting operations of the super-heavy single-tube pile body 6. The lifting platform is usually hydraulically driven, and the height of the device is adjusted through the lifting mechanism to adapt to different operating requirements. The clamping arm is designed as an adjustable structure, which can accurately clamp and firmly fix the super-heavy single-tube pile body 6 according to the size and weight changes of the super-heavy single-tube pile body 6 to prevent it from shifting or tilting during transportation and installation. The application of this lifting and clamping device 5 draws on the working principles of the common lifting platform and clamping arm in the prior art, and has a mature structure and reliable operating performance.

[0023] During operation, when it is necessary to place the super-heavy single-tube pile body 6 on the roll-on / roll-off device body 4, the operator can use the lifting equipment to lift the super-heavy single-tube pile body 6 to the top position of the roll-on / roll-off device body 4, and accurately place it above the connecting bridge 7 between the two roll-on / roll-off device bodies 6. After the super-heavy single-tube pile body 6 is in place, the lifting and clamping device 5 is operated to gradually descend, and the super-heavy single-tube pile body 6 is clamped inside the lifting and clamping device 5. Then the operator can start the roll-on / roll-off device body 4 to move on the track 1. When the roll-on / roll-off device body 4 moves, the extrusion spring 207 squeezes the push plate 208, so that the push plate 208 drives the limit plate 203 to descend. The descent of the limit plate 203 can make the cleaning brush 1 210, the cleaning brush 211 and the cleaning brush fit the track 1, remove the debris around the track 1, and keep the track 1 clean, thereby reducing the rolling resistance and ensuring the smooth operation of the roll-on / roll-off device body 4. If there are debris of large mass on the track 1, the descent of the limit plate 203 will be blocked, thereby pushing the two rubber plates 213. The movement of the rubber plate 213 drives the sleeve 209 to slide forward, thereby pushing the trigger rod 215 to press the two push-type power switches 217. At this time, the push-type power switches 217 are triggered, and the movement of the roll-on / roll-off device body 4 is automatically stopped. The operator can quickly detect the existence of obstacles and promptly remove foreign objects around the track 1 to ensure that the roll-on / roll-off device body 4 continues to operate normally.

[0024] Embodiment 2: On the basis of the first embodiment, a detection mechanism 3 is provided on one side of the obstacle avoidance and removal mechanism 2. The detection mechanism 3 includes an L-shaped bending plate 301, a side plate 302, an alarm 303, an installation arc plate 304, an extension plate 305, a ball 306, a spring rod 307 and a trigger end 308. The bottom end of the L-shaped bending plate 301 is fixedly connected to a fixing plate 309, and alarms 303 are installed on both sides of the top of the fixing plate 309. The specific model of the alarm 303 is Honeywell WLR Series, the bottom end of the fixed plate 309 is fixedly connected with four side plates 302, the middle parts of two adjacent side plates 302 are embedded with spring rods 307, the free ends of the spring rods 307 are fixedly connected with the mounting arc plate 304, the inner wall of the mounting arc plate 304 is rotatably connected with the ball 306, the top of the mounting arc plate 304 is fixedly connected with the extension plate 305, one side of the extension plate 305 is provided with a trigger end 308, the trigger end 308 is electrically connected to the alarm 303, and the specific model of the trigger end 308 is Siemens 3RA Series, the L-shaped bending plate 301 is fixedly connected to the top of the connecting plate 201, the ball 306 is attached to the inner wall of the track 1, and the trigger end 308 is fixedly connected to the inner side of the side plate 302. It should be noted that the spring rod 307 can be used to reset the mounting arc plate 304 so that the ball 306 always fits the side wall of the track 1.

[0025] Whenever the roll-on / roll-off device body 4 moves along the track 1, the ball 306 embedded in the track 1 will slide against the inner wall of the track 1. If the track 1 is deformed or blocked by an obstacle, the ball 306 will be squeezed by the track 1 or the obstacle, thereby pushing the installation arc plate 304 to move. The displacement will drive the extension plate 305 to squeeze the trigger end 308, and the trigger end 308 will further activate the alarm 303. Once the alarm 303 is activated, the operator can get an immediate reminder and take quick measures to eliminate the obstacle or perform maintenance to ensure the safe operation of the roll-on / roll-off device body 4.
