Description

Technical Field

[0001] This invention relates to the field of marine equipment, and more particularly to a ship repair and handling equipment. Background Technology

[0002] Ships are tools that move by floating on water using buoyancy. Some small boats in scenic areas, due to their small size and light weight, are often moved using trolley-type transport equipment to reduce costs during maintenance. The process involves first pushing the transport equipment onto a floating platform on the water, and then using a towing rope on the equipment to tow the boat onto the transport equipment. However, during towing, because the boat exerts a pulling force on the transport equipment, multiple workers are needed to apply significant pulling force to prevent the equipment from shifting, making the towing process less than effortless. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a ship repair and handling equipment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a ship repair and handling equipment, including a ship towing vehicle, a screw pusher is provided at the lower rear of the ship towing vehicle, connecting seats are fixedly installed at both sides of the lower edge of the ship towing vehicle, and a barrier is rotatably installed at the ends of the two connecting seats. An H-shaped frame is slidably installed inside the barrier, the H-shaped frame extends through the end of the barrier, and an unfolding frame is rotatably installed at the rear edge of the H-shaped frame. The unfolding frame is connected to the screw pusher, an anti-tilting component is provided on the H-shaped frame, a second magnet is fixedly installed on the inner side of the barrier, a tugboat component is provided at the upper rear of the ship towing vehicle, and a guide component is provided at the front end of the ship towing vehicle.

[0005] Preferably, the tugboat component includes a towing disc rotatably mounted on the upper rear of the ship towing vehicle, a towing rope wound on the towing disc, and a first brake motor fixedly mounted on the side of the upper rear of the ship towing vehicle near the towing disc, the output end of the first brake motor being fixed to the towing disc.

[0006] Preferably, the guide includes a guide frame rotatably mounted on the front end of the ship towing vehicle, and a second brake motor is fixedly mounted on the front edge of the side of the ship towing vehicle, with the output end of the second brake motor fixed to the guide frame.

[0007] Preferably, the screw actuator includes a rod frame fixedly installed at the lower rear of the ship towing vehicle. A threaded rod is rotatably installed through the inside of the rod frame, and a threaded sleeve is screwed onto the outer surface of the threaded rod. The two ends of the threaded sleeve extend from both sides of the rod frame, and the threaded sleeve is slidably engaged with the rod frame. The end of the unfolding frame is rotatably connected to the end of the threaded sleeve. A servo motor is fixedly installed at the lower rear of the ship towing vehicle behind the rod frame, and the output end of the servo motor is fixed to the threaded rod.

[0008] Preferably, a positioning seat is fixedly installed on the side of the connecting seat, a No. 1 magnet is fixedly installed through the end of the positioning seat, and a battery is fixedly installed at the upper rear edge of the ship towing vehicle.

[0009] Preferably, the anti-tilting component includes a connecting shaft that is rotatably mounted through the end of the H-shaped frame. A bearing frame is fixedly mounted on the outer surface of the connecting shaft. A steering gear is coaxially fixedly mounted on the end of the connecting shaft. A steering gear meshes with a steering tooth plate at the lower part of the steering gear. A sliding column is fixedly mounted on the end of the steering tooth plate. A positioning frame is fixedly mounted on the upper edge of the sliding column. A positioning ear extends from the upper edge of the enclosure. The sliding column is elastically connected to the H-shaped frame.

[0010] Preferably, a frame shaft is rotatably mounted through the lower end of the support frame, a bracket is fixedly mounted on the outer surface of the frame shaft, a lug is fixedly mounted on the end of the frame shaft, a first movable frame is rotatably mounted on the end of the lug, a curved frame is rotatably mounted on the end of the first movable frame, the curved frame is elastically connected to the support frame, a control top block is slidably mounted through the lower part of the support frame, a second movable frame is rotatably mounted on the rear end of the control top block, and the end of the second movable frame is rotatably connected to the curved frame.

[0011] Preferably, a boss is slidably mounted on the outer surface of the sliding column, and the end of the boss is fixed to the H-shaped frame. A second return spring is wound around the outer side of the sliding column, and the two ends of the second return spring are fixed to the boss and the steering gear plate, respectively. A fixed column is slidably mounted through the end of the bending frame, and connecting ears are fixedly mounted at both the upper and lower ends of the fixed column. The ends of the connecting ears are fixed to the bearing frame. A first return spring is wound around the outer side of the fixed column, and the two ends of the first return spring are fixed to the end of the bending frame and the connecting ear below, respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The movable deployment frame can push the H-shaped frame, thereby causing the barrier to rotate. This allows the barrier under the ship to tug to rotate out from both sides and press against the guardrail of the floating platform. During subsequent towing, the resistance formed between the barrier and the guardrail can reduce the force required for the ship to tug to move forward, thus reducing the pulling force exerted by the workers on the ship to tug and making it easier to tow the ship.

[0013] 2. When the hull rotates out from both sides and rests against the positioning seat, the hull will stop rotating. At this time, the unfolding frame continues to push the H-shaped frame, allowing the H-shaped frame to slide inside the hull. During this process, the positioning frame will abut against the positioning lugs on the hull, stopping the steering gear plate from moving. Then, the unfolding frame continues to push the H-shaped frame, thereby driving the steering gear to roll on the stopped steering gear plate, allowing the support frame to flip down. During the flipping process, the control block will remain stationary against the floating platform. At this time, the support frame continues to flip down to drive the second movable frame to move, thereby pushing the curved frame down to drive the first movable frame to move, pushing the lever lugs down, and then driving the bracket to flip up around the frame shaft and stick to the lower end of the floating platform. This restraint ensures that when the ship is first moved onto the ship towing vehicle during subsequent towing, the ship towing vehicle will not experience a stern lifting due to the weight on the front, thereby improving the stability of the ship during towing.

Detailed Implementation

[0016] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] like Figures 1-9The illustrated ship repair and handling equipment includes a ship towing tractor 1. A screw-driven component is located at the lower rear of the ship towing tractor 1. Connecting seats 18 are fixedly installed on both sides of the lower edge of the ship towing tractor 1. A barrier 3 is rotatably mounted at the end of each connecting seat 18. The barrier 3 can abut against the guardrail 5 to create resistance and reduce the force required to move the ship towing tractor 1 forward. The number of barriers 3 can be increased as needed to ensure the resistance between the barriers 3 and the guardrail 5 is sufficient. The connecting seats 18 provide support for the barriers 3. An H-shaped frame 26 is slidably installed inside the barrier 3, extending from one end of the barrier 3. The sliding design between the barrier 3 and the H-shaped frame 26 shortens the total length of the flattened support frame 12, bracket 11, barrier 3, and H-shaped frame 26, ensuring that the barrier 3 can smoothly rotate out from the gap in the guardrail 5. An unfolding frame 17 is rotatably mounted at the rear edge of the H-shaped frame 26. The unfolding frame 17 is connected to the screw pusher. The H-shaped frame 26 is equipped with an anti-tilting component. The inner side of the barrier 3 is fixedly installed with a second magnet 23. When the unfolding frame 17 first pushes the H-shaped frame 26, the barrier 3 will rotate first because the H-shaped frame 26 is attracted and fixed inside the barrier 3 by the second magnet 23, while the H-shaped frame 26 remains stationary inside the barrier 3. The upper rear of the ship towing vehicle 1 is equipped with a tugboat component, and the front end of the ship towing vehicle 1 is equipped with a guide component. The moving unfolding frame 17 can push the H-shaped frame 26, thereby driving the barrier 3 to rotate. This allows the barrier 3 below the ship towing vehicle 1 to rotate out from both sides and press against the guardrail 5 of the floating platform 4. This allows the resistance formed between the barrier 3 and the guardrail 5 to reduce the forward force of the ship towing vehicle 1 during the subsequent towing process, thereby reducing the pulling force applied by the workers to the ship towing vehicle 1 and making it easier to tow the ship.

[0018] The tugboat assembly includes a towing disc 7 rotatably mounted on the upper rear of the vessel towing vehicle 1. A towing rope 8 is wound on the towing disc 7. A first brake motor 9 is fixedly mounted on the side of the upper rear of the vessel towing vehicle 1 near the towing disc 7. The output end of the first brake motor 9 is fixed to the towing disc 7. The first brake motor 9 drives the towing disc 7 to rotate, thereby winding the towing rope 8 and towing the vessel onto the vessel towing vehicle 1.

[0019] The guide includes a guide frame 2 rotatably mounted on the front end of the ship towing vehicle 1. A second brake motor 10 is fixedly mounted on the front edge of the side of the ship towing vehicle 1. The output end of the second brake motor 10 is fixed to the guide frame 2. The second brake motor 10 controls the guide frame 2 to tilt downwards to a tilted state, so that the ship can be towed to the ship towing vehicle 1 under the guidance of the guide frame 2.

[0020] The screw actuator includes a rod frame 15 fixedly installed at the lower rear of the ship towing vehicle 1. A threaded rod 16 is rotatably mounted inside the rod frame 15, and the rod frame 15 serves to support the threaded rod 16. A threaded sleeve 19 is screwed onto the outer surface of the threaded rod 16, and the threaded rod 16 drives the threaded sleeve 19 to move. The two ends of the threaded sleeve 19 extend from both sides of the rod frame 15 and are slidably engaged with the rod frame 15. The end of the unfolding frame 17 is rotatably connected to the end of the threaded sleeve 19. A servo motor 14 is fixedly installed at the lower rear of the ship towing vehicle 1 behind the rod frame 15. The output end of the servo motor 14 is fixed to the threaded rod 16. The servo motor 14 drives the threaded rod 16 to rotate, thereby driving the threaded sleeve 19 to move, so as to drive the unfolding frame 17 to move.

[0021] A positioning seat 21 is fixedly installed on the side of the connecting seat 18. The positioning seat 21 can position the rotating enclosure 3 so that when the subsequent unfolding frame 17 continues to push the H-shaped frame 26, the H-shaped frame 26 can slide inside the enclosure 3 while the enclosure 3 remains stationary. A first magnet 22 is fixedly installed through the end of the positioning seat 21. Under the attraction of the first magnet 22, the enclosure 3 can be fixed so that when the subsequent unfolding frame 17 moves in the opposite direction to drive the H-shaped frame 26 to reset, the H-shaped frame 26 can first slide inside the enclosure 3 to the second magnet 23, and then drive the enclosure 3 to rotate and reset to below the ship towing vehicle 1. A battery 6 is fixedly installed at the upper rear edge of the ship towing vehicle 1. The battery 6 serves to provide power.

[0022] The anti-tilting component includes a connecting shaft 36 that is rotatably mounted through the end of the H-shaped frame 26. A support frame 12 is fixedly mounted on the outer surface of the connecting shaft 36. The connecting shaft 36 serves to allow the support frame 12 to rotate. A steering gear 35 is coaxially fixedly mounted at the end of the connecting shaft 36. A steering tooth plate 37 meshes with the lower part of the steering gear 35. The cooperation between the steering gear 35 and the steering tooth plate 37 can control the support frame 12 to tilt downwards. A sliding column 20 is fixedly mounted at the end of the steering tooth plate 37. A positioning frame 25 is fixedly mounted at the upper edge of the sliding column 20. A positioning ear 24 extends from the upper edge of the barrier 3. The cooperation between the positioning frame 25 and the positioning ear 24 can position the moving position of the steering tooth plate 37. The sliding column 20 is elastically connected to the H-shaped frame 26.

[0023] A shaft 29 is rotatably mounted through the lower end of the support frame 12. A bracket 11 is fixedly mounted on the outer surface of the shaft 29, which supports the bracket 11. A lug 30 is fixedly mounted at the end of the shaft 29, and a first movable frame 28 is rotatably mounted at the end of the lug 30. A bent frame 27 is rotatably mounted at the end of the first movable frame 28. The bent frame 27 is elastically connected to the support frame 12 and can drive the first movable frame 28 to move and push the lug 30. A control top block 13 is slidably mounted through the lower part of the support frame 12, and a second movable frame 31 is rotatably mounted at the rear end of the control top block 13. The end of 31 is rotatably connected to the curved frame 27. During the downward tilting of the support frame 12, the control top block 13 will press against the floating platform 4 and remain stationary. At this time, the support frame 12 continues to tilt downward to drive the second movable frame 31 to move, thereby pushing the curved frame 27 to move downward, thereby driving the first movable frame 28 to move, pushing the lug 30 to tilt downward, and then driving the bracket 11 to tilt upward around the frame shaft 29 and stick to the lower end of the floating platform 4 to restrict it, so as to ensure that when the ship is moved onto the ship towing vehicle 1 during the subsequent towing process, the ship towing vehicle 1 will not have its stern tilted up due to the weight on the front, thereby improving the stability of the ship during towing.

[0024] A boss 38 is slidably mounted on the outer surface of the sliding column 20. The end of the boss 38 is fixed to the H-shaped frame 26. The boss 38 serves to allow the sliding column 20 to slide. A second return spring 39 is wound around the outside of the sliding column 20. The two ends of the second return spring 39 are fixed to the boss 38 and the steering gear 37, respectively. The second return spring 39 serves to reset the steering gear 37. A fixed column 33 is slidably mounted through the end of the curved frame 27. Connecting ears 32 are fixedly mounted at both the upper and lower ends of the fixed column 33. The connecting ears 32 serve to fix the fixed column 33. The end of the connecting ears 32 is fixed to the bearing frame 12. A first return spring 34 is wound around the outside of the fixed column 33. The first return spring 34 can reset the curved frame 27, thereby resetting the bracket 11. The two ends of the first return spring 34 are fixed to the end of the curved frame 27 and the lower connecting ear 32, respectively.

[0025] During ship towing, the ship towing vehicle 1 is pushed to the edge of the floating platform 4. Then, the servo motor 14 drives the threaded rod 16 to rotate, which in turn moves the threaded sleeve 19, thereby driving the deployment frame 17 to move. The moving deployment frame 17 pushes the H-shaped frame 26, which in turn rotates the barrier 3, allowing the barrier 3 under the ship to rotate out from both sides and press against the guardrail 5 of the floating platform 4. This allows the resistance formed between the barrier 3 and the guardrail 5 to reduce the impact during subsequent ship towing. The force of the ship towing trolley 1 moving forward reduces the pulling force applied to the ship towing trolley 1 by the workers. When the barrier 3 rotates out from both sides and presses against the guardrail 5, the barrier 3 just contacts the positioning seat 21, so that the barrier 3 stops rotating under the positioning seat 21. Then the unfolding frame 17 continues to push the H-shaped frame 26. At this time, the H-shaped frame 26 will detach from the attraction of the second magnet 23 inside the barrier 3, allowing the H-shaped frame 26 to slide inside the barrier 3. During this sliding process, the positioning frame 25 will abut against the positioning lug 24 on the barrier 3, allowing... The steering gear 37 stops moving, and then the unfolding frame 17 continues to push the H-shaped frame 26, thereby causing the steering gear 35 to roll on the stopped steering gear 37, allowing the support frame 12 to tilt downwards. During the tilting process, the control block 13 will remain stationary against the floating platform 4. At this time, the support frame 12 continues to tilt downwards to drive the second movable frame 31 to move, thereby pushing the curved frame 27 downwards, which in turn drives the first movable frame 28 to move, pushing the lever 30 downwards, and then causing the bracket 11 to tilt upwards around the frame shaft 29 and press against the floating platform. The lower end of the moving platform 4 is used to restrict it, so as to ensure that when the ship is first moved onto the ship towing vehicle 1 during the subsequent towing process, the stern of the ship towing vehicle 1 will not lift up due to the weight on the front. Then, the guide frame 2 is tilted down by the second brake motor 10, and the towing rope 8 is fixed to the ship. Then, the towing disc 7 is rotated by the first brake motor 9 to wind the towing rope 8, thereby towing the ship onto the ship towing vehicle 1, and then the ship can be transported and repaired.
