Abstract

This invention relates to the field of ship docking technology and discloses an inland waterway vessel push-connection and locking device, including a push-boat and a barge. A push-mounted frame is fixedly connected to the side wall of the push-boat, and a positioning groove is provided on the inner wall of the barge. The outer wall of the push-mounted frame is slidably connected to the inner wall of the positioning groove. A placement groove is provided on the inner wall of the barge. When the electric telescopic rod is activated, it retracts, causing the sliding plate and sliding disc to rise, thus raising the positioning rod. Through the support assembly, the arc-shaped support block contacts the positioning hole of the push-mounted frame. Through the insertion assembly, the positioning rod moves in multiple directions, so that multiple arc-shaped support blocks simultaneously contact the positioning hole of the push-mounted frame.

Description

Technical Field

[0001] This invention relates to the field of ship docking equipment technology, specifically to a jacking connection and locking device for inland waterway vessels. Background Technology

[0002] The ship jacking connection locking device is a special device used to securely connect a jacking boat to a barge. It rigidly or flexibly connects a jacking boat and one or more barges to form a whole that hardly produces relative displacement during navigation, like a water "train". It makes the two form a whole and achieves efficient transportation. It can transmit thrust, withstand various navigation forces, and ensure the stability of the fleet. The common connection method is that a steel jacking frame is installed at the bow of the jacking boat and a groove (jacking beam or dock-shaped groove) is provided at the stern of the barge. During operation, the jacking boat inserts the jacking frame into the groove of the barge and then locks it in place using cables, positioning pins or wedges.

[0003] When a pusher propels a barge for a long distance, locating pins are usually inserted into the locating holes of the pusher frame to maintain stability. However, when the pusher and barge are on the water, they are affected by the waves, which may cause them to float up and down, leading to frequent changes in their positions. This makes it difficult for the locating pins to align with the locating holes, affecting docking efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an inland waterway vessel push-connection locking device, including a push-pull vessel and a barge. A push-pull frame is fixedly connected to the side wall of the push-pull vessel, a positioning groove is opened on the inner wall of the barge, the outer wall of the push-pull frame is slidably connected to the inner wall of the positioning groove, and a placement groove is opened on the inner wall of the barge.

[0005] The lifting mechanism is fixedly installed on the inner wall of the placement slot to be close to the jacking frame;

[0006] A positioning mechanism is installed on top of the lifting mechanism to limit the position of the jacking frame;

[0007] A fixing mechanism is fixedly installed on top of the lifting mechanism to restrict the movement of the positioning mechanism;

[0008] In use, when the pusher needs to move the barge, the operator drives the pusher to align the pusher frame with the positioning slot, and then uses the pusher to insert the pusher frame into the positioning slot.

[0009] Preferably, the lifting mechanism includes:

[0010] The drive component is fixedly installed on the inner wall of the placement slot;

[0011] The push component is slidably positioned on the inner wall of the placement slot via a slider;

[0012] The sliding component includes a sliding disc that is slidably connected to the inner wall of the placement groove;

[0013] After the pusher enters the positioning slot, the drive component drives the pusher component to rise, pushing the positioning mechanism closer to the pusher.

[0014] Preferably, the positioning mechanism includes:

[0015] A plug-in assembly is mounted on top of the sliding disk;

[0016] A support component is slidably disposed on the inner wall of the plug-in component;

[0017] When the push component rises, it will drive the plug-in component and the support component to rise until the support component contacts the top of the inner wall of the positioning groove, thereby causing the support component to squeeze the push frame.

[0018] Preferably, the fixing mechanism includes:

[0019] The pressing component is fixedly mounted on the top of the sliding disk;

[0020] The extrusion assembly is slidably disposed on the inner wall of the pressing assembly;

[0021] When the push component rises, it also drives the pressing component and the squeezing component to rise. When the support component and the top of the inner wall of the positioning groove come into contact, the pressing component will also come into contact with the top of the inner wall of the placement groove, causing the squeezing component to squeeze the insertion component.

[0022] Preferably, the drive assembly includes an electric telescopic rod fixedly connected to the inner wall of the placement slot, a sliding plate slidably connected to the inner wall of the placement slot, and the bottom of the output end of the electric telescopic rod fixedly connected to the top of the sliding plate.

[0023] Preferably, the pushing component includes four limiting holes formed in the inner wall of the sliding disk, and the outer wall of the sliding disk is fixedly connected to the side wall of the sliding plate;

[0024] When the jacking frame enters the positioning slot, the electric telescopic rod is activated to retract, causing the sliding plate and sliding disc to rise and move towards the jacking frame.

[0025] Preferably, the plug-in assembly includes a positioning rod disposed on the top of the sliding disk, and four spring rods are fixedly connected to the bottom of the positioning rod. The bottom of the four spring rods is fixedly connected to the bottom of the inner wall of the four limiting holes by springs.

[0026] When the sliding plate rises, it pushes the spring of the spring rod to move, thereby causing the spring rod and the positioning rod to rise. As the positioning rod continues to move, due to the excessive gap between the positioning rod and the positioning hole of the pusher frame, the positioning rod will easily enter the pusher frame.

[0027] Preferably, the support assembly includes a spring compression rod slidably connected to the inner wall of the positioning rod, three arc-shaped support blocks slidably connected to the inner wall of the positioning rod, the outer wall of the spring compression rod having a slope, and the side walls of the three arc-shaped support blocks all having slopes.

[0028] When the positioning rod moves, it drives the spring compression rod and the arc-shaped support block to move synchronously, so that the spring compression rod contacts the top of the inner wall of the positioning groove. As the positioning rod continues to move, the spring compression rod will be squeezed and moved downward. Since the inclined surface of the spring compression rod is in contact with the inclined surface of the arc-shaped support block, the spring compression rod will squeeze the arc-shaped support block to move, so that the arc-shaped support block contacts the positioning hole of the pusher frame. When the pusher boat and barge are swayed by the waves on the water surface, the spring compression rod is difficult to align with the center of the positioning hole of the pusher frame. Therefore, it is difficult for multiple arc-shaped support blocks to contact the positioning hole of the pusher frame synchronously.

[0029] At this point, the spring rod allows it to move laterally, which in turn causes the positioning rod to move in multiple directions. When a single arc-shaped support block contacts the positioning hole of the pusher frame, the arc-shaped support block is continuously subjected to the compressive force of the spring compression rod, which then reacts on the spring compression rod. Since the spring compression rod is blocked by the top of the inner wall of the positioning groove and cannot move upward, it pushes the positioning rod to move, changing the position of the positioning rod and the arc-shaped support block. This allows multiple arc-shaped support blocks to simultaneously contact the positioning hole of the pusher frame, supporting the pusher frame. Through the application of the above components, the positioning rod can be quickly and accurately inserted into the positioning hole, effectively preventing the positioning rod and positioning hole from being difficult to align due to the swaying of the pusher boat and barge, which would make docking difficult. This reduces the difficulty for operators to repeatedly fine-tune the position of the pusher boat, shortens the docking time of the pusher boat and barge, and enables the two to dock quickly.

[0030] Preferably, the pressing assembly includes a hydraulic cylinder fixedly connected to the top of the sliding disc, a spring ring slidably connected to the inner wall of the hydraulic cylinder, and hydraulic oil disposed on the inner wall of the hydraulic cylinder.

[0031] Preferably, the extrusion assembly includes a piston ring slidably connected to the inner wall of the hydraulic cylinder, the top of the piston ring being fixedly connected to the bottom of the spring ring, and a sealing ring being fixedly connected to the outer wall of the piston ring.

[0032] Eight spring piston rods are slidably connected to the inner wall of the spring ring. Each of the eight spring piston rods is fixedly connected to a compression rod on the side near the sliding disc. Each of the eight spring piston rods is fixedly connected to a sealing ring on the outer wall.

[0033] When the sliding plate rises, it also drives the hydraulic cylinder and spring ring to rise. When multiple arc-shaped support blocks contact the positioning holes of the pusher frame, the sliding plate continues to rise, which will squeeze the spring of the spring rod, causing it to accumulate rebound force. The spring ring will then contact the top of the inner wall of the placement groove, as shown at position G in the figure. The spring ring will be squeezed and move downward, accumulating rebound force. It will also drive the piston ring to move, causing the piston ring to squeeze the hydraulic oil in the hydraulic cylinder. The hydraulic oil will squeeze multiple spring piston rods and squeeze rods to move, causing the spring piston rods to accumulate rebound force.

[0034] The extrusion rod moves towards the positioning rod, bringing it into contact with the positioning rod. Due to the lateral movement of the positioning rod, multiple extrusion rods cannot simultaneously contact the positioning rod. Once the extrusion rod contacts the positioning rod, it stops moving, and the hydraulic oil concentrates to compress the remaining extrusion rods into contact with the positioning rod, thereby restricting the movement of the positioning rod and keeping it stable. This reduces the positional deviation of the positioning rod during navigation, allowing the pusher vessel to push the barge stably via the positioning rod. It also restricts the relative movement between the two vessels in the horizontal and vertical planes, thus efficiently transmitting thrust.

[0035] The present invention has the following beneficial effects:

[0036] (1) When using this invention, the pusher frame is moved into the positioning slot. Then, the electric telescopic rod is retracted, which drives the sliding plate and sliding disc to rise, so that the positioning rod rises. The support component makes the arc-shaped support block contact the positioning hole of the pusher frame. The plug-in component makes the positioning rod move in multiple directions, so that multiple arc-shaped support blocks contact the positioning hole of the pusher frame simultaneously. Through the application of the above components, the positioning rod is quickly and accurately inserted into the positioning hole, which effectively prevents the positioning rod and positioning hole from being difficult to align due to the shaking of the pusher boat and barge, which would make it difficult for the two to dock. This reduces the difficulty for operators to repeatedly fine-tune the position of the pusher boat, shortens the docking time of the pusher boat and barge, and enables the two to dock quickly.

[0037] (2) When the sliding plate rises, the hydraulic cylinder and spring ring will also rise. When multiple arc-shaped support blocks are in contact with the positioning holes of the pusher frame, the sliding plate continues to rise and will squeeze the spring of the spring rod. The squeezing assembly will restrict the movement of the positioning rod by multiple squeezing rods, keep the positioning rod stable, reduce the positional deviation of the positioning rod during navigation, and enable the pusher boat to push the barge to move stably through the positioning rod. This restricts the relative movement between the two boats in the horizontal and vertical planes, thereby efficiently transmitting thrust.

[0038] (3) When the barge is loading and unloading cargo, and the barge's draft changes, the electric telescopic rod is activated to extend a certain distance, allowing the sliding plate, hydraulic cylinder, and positioning rod to descend. The descent of the hydraulic cylinder also cancels the fixing of the positioning rod, allowing the positioning rod to move in multiple directions. This ensures that when the barge's draft changes, the pusher and the barge remain connected. Throughout the dynamic adjustment process, the positioning rod never leaves the positioning hole of the pusher frame, and the connection between the two vessels is not interrupted. This reduces the impact of the large sway caused by the change in the barge's draft on the pusher, enabling the fleet to load and unload cargo without disconnecting the connection, while maintaining the balance of the pusher.

[0039] (4) After the barge loading and unloading is completed and the barge's draft is stable, the sliding plate is raised by retracting the electric telescopic rod again, so that the arc-shaped support block squeezes the positioning hole of the pusher frame, and the squeezing rod squeezes the positioning rod, so that the positioning rod remains stable. The pusher barge and the barge are in a relaxed state and quickly return to the connected state. Compared with the pusher barge and the barge re-connecting, it is faster and more accurate.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1, please refer to Figures 1-4 The present invention is a jacking connection and locking device for inland waterway vessels, including a jacking vessel 13 and a barge 14. A jacking frame 15 is fixedly connected to the side wall of the jacking vessel 13. A positioning groove 16 is provided on the inner wall of the barge 14. The outer wall of the jacking frame 15 is slidably connected to the inner wall of the positioning groove 16. A placement groove 17 is provided on the inner wall of the barge 14.

[0054] Lifting mechanism 1 is fixedly installed on the inner wall of the placement slot 17 and is used to approach the pusher 15;

[0055] Positioning mechanism 2 is installed on the top of lifting mechanism 1 to limit the position of the jacking frame 15;

[0056] The fixing mechanism 3 is fixedly installed on the top of the lifting mechanism 1 to restrict the movement of the positioning mechanism 2;

[0057] In use, when the pusher boat 13 needs to move the barge 14, the operator drives the pusher boat 13 to align the pusher frame 15 with the positioning groove 16, and then uses the pusher boat 13 to insert the pusher frame 15 into the positioning groove 16.

[0058] Lifting mechanism 1 includes:

[0059] Drive component 11 is fixedly disposed on the inner wall of placement slot 17;

[0060] Push component 12 is slidably disposed on the inner wall of placement groove 17 via a slider;

[0061] The sliding component includes a sliding disk 121 that is slidably connected to the inner wall of the placement groove 17;

[0062] When the pusher 15 enters the positioning slot 16, the drive component 11 drives the push component 12 to rise, pushing the positioning mechanism 2 closer to the pusher 15.

[0063] Positioning mechanism 2 includes:

[0064] The plug-in assembly 21 is mounted on the top of the sliding disk 121;

[0065] Support component 22 is slidably disposed on the inner wall of plug-in component 21;

[0066] When the push component 12 rises, it will drive the plug-in component 21 and the support component 22 to rise until the support component 22 contacts the top of the inner wall of the positioning groove 16, thereby causing the support component 22 to squeeze the push frame 15.

[0067] Fixed mechanism 3 includes:

[0068] Press component 31 is fixedly disposed on the top of sliding disk 121;

[0069] The extrusion assembly 32 is slidably disposed on the inner wall of the pressing assembly 31;

[0070] When the push component 12 rises, it also drives the pressing component 31 and the squeezing component 32 to rise. When the support component 22 and the top of the inner wall of the positioning groove 16 come into contact, the pressing component 31 will also come into contact with the top of the inner wall of the placement groove 17, causing the squeezing component 32 to squeeze the insertion component 21.

[0071] Example 2, please refer to Figures 4-9 The present invention is a jacking connection and locking device for inland waterway vessels. Based on Example 1, the drive assembly 11 includes an electric telescopic rod 111 fixedly connected to the inner wall of the placement groove 17, and a sliding plate 112 slidably connected to the inner wall of the placement groove 17. The bottom of the output end of the electric telescopic rod 111 is fixedly connected to the top of the sliding plate 112.

[0072] The pushing component 12 includes four limiting holes 122 formed on the inner wall of the sliding disk 121, and the outer wall of the sliding disk 121 is fixedly connected to the side wall of the sliding plate 112.

[0073] When the pusher 15 enters the positioning groove 16, the electric telescopic rod 111 is activated to retract, which drives the sliding plate 112 and the sliding disk 121 to rise and move towards the pusher 15.

[0074] The plug-in assembly 21 includes a positioning rod 211 disposed on the top of the sliding disk 121. Four spring rods 212 are fixedly connected to the bottom of the positioning rod 211. The bottom of the four spring rods 212 is fixedly connected to the bottom of the inner wall of the four limiting holes 122 through springs.

[0075] When the sliding plate 121 rises, it pushes the spring of the spring rod 212 to move, thereby causing the spring rod 212 and the positioning rod 211 to rise. As the positioning rod 211 continues to move, because the gap between the positioning rod 211 and the positioning hole of the pusher 15 is too large, the positioning rod 211 will easily enter the pusher 15.

[0076] The support assembly 22 includes a spring compression rod 221 slidably connected to the inner wall of the positioning rod 211. Three arc-shaped support blocks 222 are slidably connected to the inner wall of the positioning rod 211. The outer wall of the spring compression rod 221 has a slope, and the side walls of the three arc-shaped support blocks 222 all have slopes.

[0077] When the positioning rod 211 moves, it will drive the spring compression rod 221 and the arc-shaped support block 222 to move synchronously, so that the spring compression rod 221 contacts the top of the inner wall of the positioning groove 16. When the positioning rod 211 continues to move, the spring compression rod 221 will be squeezed and moved downward. Since the inclined surface of the spring compression rod 221 is in contact with the inclined surface of the arc-shaped support block 222, the spring compression rod 221 will squeeze the arc-shaped support block 222 to move, so that the arc-shaped support block 222 contacts the positioning hole of the push frame 15. When the push boat 13 and the barge 14 are shaken by the waves on the water surface, the spring compression rod 221 is difficult to align with the center of the positioning hole of the push frame 15. Therefore, multiple arc-shaped support blocks 222 are difficult to contact the positioning hole of the push frame 15 synchronously.

[0078] At this time, the spring of spring rod 212 allows it to move laterally, which in turn causes positioning rod 211 to move in multiple directions. When a single arc-shaped support block 222 contacts the positioning hole of the pusher 15, the arc-shaped support block 222 is continuously subjected to the compressive force of spring compression rod 221, which will then react on spring compression rod 221. Since spring compression rod 221 is blocked by the top of the inner wall of positioning groove 16 and cannot move upward, it will push positioning rod 211 to move, changing the position of positioning rod 211 and arc-shaped support. The position of block 222 allows multiple arc-shaped support blocks 222 to simultaneously contact the positioning holes of the pusher frame 15, supporting the pusher frame 15. Through the application of the above components, the positioning rod 211 can be quickly and accurately inserted into the positioning hole, effectively preventing the positioning rod 211 and the positioning hole from being difficult to align due to the shaking of the pusher boat 13 and the barge 14, which would make it difficult for the two to dock. This reduces the difficulty for operators to repeatedly fine-tune the position of the pusher boat 13, shortens the docking time of the pusher boat 13 and the barge 14, and enables the two to dock quickly.

[0079] The pressing assembly 31 includes a hydraulic cylinder 311 fixedly connected to the top of the sliding disc 121. A spring ring 312 is slidably connected to the inner wall of the hydraulic cylinder 311, and hydraulic oil is provided on the inner wall of the hydraulic cylinder 311.

[0080] The extrusion assembly 32 includes a piston ring 321 that is slidably connected to the inner wall of the hydraulic cylinder 311. The top of the piston ring 321 is fixedly connected to the bottom of the spring ring 312, and a sealing ring is fixedly connected to the outer wall of the piston ring 321.

[0081] Eight spring piston rods 322 are slidably connected to the inner wall of the spring ring 312. Each of the eight spring piston rods 322 is fixedly connected to a compression rod 323 on the side of the sliding disk 121. Each of the eight spring piston rods 322 is fixedly connected to a sealing ring on the outer wall of the spring piston rods 322.

[0082] When the sliding plate 121 rises, it also drives the hydraulic cylinder 311 and spring ring 312 to rise. Once the multiple arc-shaped support blocks 222 are in contact with the positioning holes of the pusher frame 15, the sliding plate 121 continues to rise, compressing the spring of the spring rod 212, causing it to accumulate restoring force. The spring ring 312 then contacts the top of the inner wall of the placement groove 17. Figure 4 As shown in the position of G, the spring ring 312 will be squeezed and move downward, accumulating rebound force, and will also drive the piston ring 321 to move, causing the piston ring 321 to squeeze the hydraulic oil in the hydraulic cylinder 311. The hydraulic oil will squeeze multiple spring piston rods 322 and squeeze rods 323 to move, causing the spring piston rod 322 to accumulate rebound force.

[0083] The compression rod 323 moves towards the positioning rod 211, making it contact with the positioning rod 211. Due to the lateral movement of the positioning rod 211, it is difficult for multiple compression rods 323 to contact the positioning rod 211 simultaneously. Once the compression rod 323 contacts the positioning rod 211, it stops moving, and the hydraulic oil concentrates to compress the remaining compression rods 323 to contact the positioning rod 211, thereby restricting the movement of the positioning rod 211 and keeping it stable. This reduces the positional deviation of the positioning rod 211 during navigation, allowing the pusher 13 to push the barge 14 to move stably via the positioning rod 211. This restricts the relative movement between the two vessels in the horizontal and vertical planes, thereby efficiently transmitting thrust.

[0084] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0085] A specific application of this embodiment is as follows: When the pusher boat 13 and the barge 14 need to dock, the operator steers the pusher boat 13 to align the pusher frame 15 with the positioning slot 16, then allows the pusher frame 15 to enter the positioning slot 16. Next, the electric telescopic rod 111 is retracted, causing the sliding plate 112 and the sliding disk 121 to rise. When the sliding disk 121 rises, it pushes the spring of the spring rod 212 to move, thereby causing the spring rod 212 and the positioning rod 211 to rise. As the positioning rod 211 continues to move, due to the continuous movement of the positioning rod 211 and the pusher... The positioning hole of the push frame 15 has too large a fitting gap, so the positioning rod 211 will easily enter the push frame 15. At this time, as the positioning rod 211 continues to move, the spring compression rod 221 will contact the top of the inner wall of the positioning groove 16. As the positioning rod 211 continues to move, the spring compression rod 221 will be squeezed and moved downward. Since the inclined surface of the spring compression rod 221 is in contact with the inclined surface of the arc-shaped support block 222, the spring compression rod 221 will squeeze the arc-shaped support block 222 to move, so that the arc-shaped support block 222 contacts the positioning hole of the push frame 15.

[0086] When the pusher boat 13 and barge 14 are rocked by the waves, the spring compression rod 221 is difficult to align with the center of the positioning hole of the pusher frame 15. Therefore, multiple arc-shaped support blocks 222 are difficult to contact the positioning hole of the pusher frame 15 simultaneously. At this time, the spring of the spring rod 212 allows the spring rod 212 to move laterally, which will cause the positioning rod 211 to move in multiple directions. When a single arc-shaped support block 222 contacts the positioning hole of the pusher frame 15, the arc-shaped support block 222 is continuously subjected to the compression force of the spring compression rod 221, which will then react on the spring compression rod 221. Since the spring compression rod 221 is located on the inner wall of the positioning groove 16, When the top is blocked and cannot move upward, it will push the positioning rod 211 to move, changing the position of the positioning rod 211 and the arc-shaped support block 222, so that multiple arc-shaped support blocks 222 simultaneously contact the positioning holes of the pusher frame 15, supporting the pusher frame 15. Through the application of the above components, the positioning rod 211 can be quickly and accurately inserted into the positioning hole, effectively preventing the positioning rod 211 and the positioning hole from being difficult to align due to the shaking of the pusher boat 13 and the barge 14, which would make it difficult for the two to dock. This reduces the difficulty for operators to repeatedly fine-tune the position of the pusher boat 13, shortens the docking time of the pusher boat 13 and the barge 14, and enables the two to dock quickly.

[0087] Secondly, as the sliding plate 121 rises, it also drives the hydraulic cylinder 311 and spring ring 312 to rise. Once the multiple arc-shaped support blocks 222 are in contact with the positioning holes of the pusher frame 15, the sliding plate 121 continues to rise, compressing the spring of the spring rod 212, causing it to accumulate restoring force. The spring ring 312 then contacts the top of the inner wall of the placement groove 17. Figure 4 As shown in the position of G, the spring ring 312 will be squeezed and move downward, accumulating rebound force, and will also drive the piston ring 321 to move, causing the piston ring 321 to squeeze the hydraulic oil in the hydraulic cylinder 311. The hydraulic oil will squeeze multiple spring piston rods 322 and squeeze rods 323 to move, causing the spring piston rod 322 to accumulate rebound force.

[0088] The compression rod 323 moves towards the positioning rod 211, making it contact with the positioning rod 211. Due to the lateral movement of the positioning rod 211, it is difficult for multiple compression rods 323 to contact the positioning rod 211 simultaneously. Once the compression rod 323 contacts the positioning rod 211, it stops moving, and the hydraulic oil concentrates to compress the remaining compression rods 323 to contact the positioning rod 211, thereby restricting the movement of the positioning rod 211 and keeping it stable. This reduces the positional deviation of the positioning rod 211 during navigation, allowing the pusher 13 to push the barge 14 to move stably via the positioning rod 211. This restricts the relative movement between the two vessels in the horizontal and vertical planes, thereby efficiently transmitting thrust.

[0089] Secondly, when the barge 14 is loading and unloading cargo, and the draft of the barge 14 changes, the electric telescopic rod 111 is activated to extend a certain distance, allowing the sliding plate 121 and hydraulic cylinder 311 to descend. At this time, because the arc-shaped support block 222 is in contact with the positioning hole of the pusher frame 15, there is a large friction between the two. Relying on the spring of the spring rod 212, it is difficult to pull the positioning rod 211 down. As the hydraulic cylinder 311 continues to move, the hydraulic cylinder 311 will then come into contact with the positioning rod 211. When the barge 14 makes contact, the positioning rod 211 is squeezed down, which releases the rebound force of the spring compression rod 221 and reduces the squeezing force on the arc-shaped support block 222. At this time, the arc-shaped support block 222 is still located in the positioning hole of the push frame 15. When the draft of the barge 14 changes and a large sway occurs, it will cause the positioning rod 211 and the arc-shaped support block 222 to sway, which will cause the arc-shaped support block 222 to contact the push frame 15, and the arc-shaped support block 222 will be squeezed and compressed back into the positioning rod 211.

[0090] Simultaneously, the descent of the hydraulic cylinder 311 releases the rebound force of the spring ring 312 and the spring piston rod 322, causing the compression rod 323 to separate from the positioning rod 211, thus removing the fixation of the positioning rod 211 and allowing it to move in multiple directions. When the positioning rod 211, which moves with the barge 14, comes into contact with the pusher frame 15, it will be squeezed and moved. This ensures that when the draft of the barge 14 changes, the pusher 13 and the barge 14 remain connected. Throughout the entire dynamic adjustment process, the positioning rod 211 never disengages from the positioning hole of the pusher frame 15, and the connection between the two vessels remains uninterrupted. This reduces the impact of the large swaying caused by changes in the draft of the barge 14 on the pusher 13, allowing the fleet to load and unload cargo without disconnecting the connection, while maintaining the balance of the pusher 13.

[0091] Secondly, after the loading and unloading of barge 14 is completed and the draft of barge 14 is stable, the sliding plate 121 is raised by retracting the electric telescopic rod 111 again, so that the arc-shaped support block 222 presses the positioning hole of the pusher frame 15, and the pressing rod 323 presses the positioning rod 211, so that the positioning rod 211 is kept stable. The pusher 13 and barge 14 are in a relaxed state and quickly return to the connected state. Compared with the re-connection of pusher 13 and barge 14, it is faster and more accurate.
