Abstract
Description
Technical Field
[0001] This utility model belongs to the field of marine transportation technology, specifically relating to a marine cargo anti-tipping device. Background Technology
[0002] As a core mode of transportation in global trade, maritime transport relies on containers or cargo boxes to carry various goods. During navigation, ships are inevitably affected by natural factors such as waves and winds, causing changes in deck posture such as tilting and rolling. These changes pose a serious threat to the stability of cargo on deck. Especially when the ship tilts at a large angle, cargo boxes are prone to tipping over due to loss of balance. This can not only cause damage to cargo and economic losses, but also potentially lead to damage to deck equipment, shift in the ship's center of gravity, and other safety hazards, even affecting navigational safety.
[0003] Currently, the main methods of securing cargo in maritime transport rely on traditional lashing straps, timber supports, or fixed brackets. These methods only restrict the horizontal movement of the container and cannot cope with the tilting caused by lateral tilting. When the tilt angle exceeds a critical value, the lashing straps are prone to breakage, and the timber or fixed brackets cannot adapt to the dynamic changes in the ship's tilting posture. When the tilt angle is too large or the tilting speed is too fast, these supports, due to their lack of cushioning capacity, are prone to breakage due to impact, leading to support failure. Some high-end maritime equipment uses simple hydraulic support devices, but these devices are mostly manually controlled, requiring crew members to judge the deck tilt situation based on experience and manually adjust the support height. The response speed is slow, making it difficult to respond in real time to sudden changes in tilt.
[0004] Therefore, given the current limitations of existing methods for securing cargo in maritime transport, such as the inability to respond to deck tilt in real time and the lack of automatic adjustment and protection mechanisms, there is an urgent need for an anti-tipping device that can monitor the levelness of cargo containers in real time and automatically adjust their posture to counteract the effects of deck tilt, ensuring that cargo containers remain stable during navigation and avoiding the risk of tipping over. Utility Model Content
[0005] To address the above problems, the purpose of this utility model is to provide a marine cargo anti-tipping device that solves the problems that existing marine cargo fixing methods cannot respond to deck tilting in real time and lack automatic adjustment and protection mechanisms.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a marine cargo anti-tipping device, comprising a base, on which a support seat three of a connecting frame is fixedly mounted; the support seat three is rotatably connected to two symmetrically arranged connecting rods via pins; the top ends of the connecting rods are rotatably connected to the left and right sides of a cargo box bracket via pins; an adjusting frame, a buffer support, and a controller are mounted on the base; the adjusting frame includes a support seat one, on which a main shaft is rotatably mounted; a connecting arm, a winding wheel one, and a winding wheel two are fixedly mounted on the main shaft. The first and second winding reels are respectively wound around one end of the first and second limiting steel cables. The other ends of the first and second limiting steel cables slide around the pulleys in the buffer support and are respectively fixed to the left and right sides of the cargo box bracket. The connecting arm is rotatably connected to one end of the hydraulic cylinder through a pin, and the other end of the hydraulic cylinder is rotatably connected to the second support seat through a pin. The second and first support seats are both fixed on the base. The cargo box bracket includes a bracket frame, and side plates are fixed on the left and right sides of the bracket frame. A monitoring module is installed on the bracket frame.
[0007] The beneficial effects of this utility model are as follows: when the deck of a ship with a fixed base tilts, the cargo box support can monitor the levelness of the bottom of the cargo box in real time, and the controller controls the extension and retraction of the hydraulic cylinder to drive the steel cable to wind up and down, thereby making the cargo box support rotate on the base, so that the cargo box support tends to be level and avoids the cargo box tilting too much and tipping over.
[0008] In order to adjust the left and right tilt angle of the cargo box bracket by winding up the steel cable;
[0009] As a further improvement to the above technical solution: the first winding wheel and the second winding wheel have the same specifications, the first limiting steel cable and the second limiting steel cable have the same length, and the winding direction of the first limiting steel cable on the first winding wheel is opposite to the winding direction of the second limiting steel cable on the second winding wheel.
[0010] The beneficial effects of this improvement are as follows: when the main shaft rotates, it drives the first and second winding wheels to rotate synchronously, thereby causing one of the first and second limit steel cables to be wound up while the other is released to the same length, thus steadily tightening and adjusting the left and right tilt angles of the cargo box bracket.
[0011] In order to achieve automatic adjustment of the tilt angle of the cargo box bracket;
[0012] As a further improvement to the above technical solution: the controller includes a PLC, a relay, and an oil circuit solenoid valve of a hydraulic cylinder. The PLC in the controller is electrically connected to a monitoring module, and the monitoring module is a tilt sensor.
[0013] The beneficial effects of this improvement are as follows: the controller can receive and process the left and right tilt angles of the cargo box bracket fed back by the monitoring module, and then control the hydraulic cylinder to extend and retract, drive the main shaft to rotate, and then wind up and unwind the steel cable, thereby realizing the automatic adjustment of the cargo box bracket angle.
[0014] To improve the safety of the adjustment frame by installing buffer supports;
[0015] As a further improvement to the above technical solution: the buffer support includes a fixed block, the fixed block is fixed on the base, the top of the fixed block is fixedly provided with a guide rod, the outer side of the guide rod is slidably fitted with a slider, the top of the guide rod is fixedly provided with a limiting plate, a spring is slidably fitted on the guide rod between the limiting plate and the slider, and a pulley is fixedly provided on the slider.
[0016] The beneficial effects of this improvement are as follows: when the ship experiences severe turbulence, the cargo box tilts rapidly to the left and right, causing one of the limiting steel cables (first and second) to bear a rapidly increasing tension. At this time, the pulley is pulled upward by the steel cable, and the spring is compressed to generate elastic buffer, effectively preventing the steel cable from being damaged or broken under impact.
[0017] To further improve the safety of the device;
[0018] As a further improvement to the above technical solution: electrical limiting components are provided on the lower left and right sides of the cargo box bracket. The electrical limiting components include supports, which are fixed on the base. A micro switch is fixed on the top of the support, and the micro switch is electrically connected to the controller.
[0019] The beneficial effect of this improvement is that when one side of the cargo box bracket presses against the contact of the micro switch, the controller controls the hydraulic cylinder to stop extending and retracting, thus preventing the hydraulic cylinder from being damaged due to exceeding its working stroke.
[0020] To further improve the safety of the device;
[0021] As a further improvement to the above technical solution: limiting brackets are fixed on the bases on both the front and rear sides of the electrical limiting component, and the top of the limiting brackets is on the same plane as the top of the base of the micro switch.
[0022] The beneficial effects of this improvement are: the limit bracket provides rigid support for the cargo box bracket and prevents the micro switch base from being damaged by compression.
[0023] In order to fully improve the stability of the cargo box support for the cargo box;
[0024] As a further improvement to the above technical solution: the cargo box bracket includes a bracket frame, and two connecting ears are welded on both sides of the bracket frame for fastening and connecting the first limiting steel cable and the second limiting steel cable. Connecting ears are also welded on both sides of the bracket frame. Connecting ears are rotatably connected to connecting rods through pins.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0033] Example 1:
[0034] like Figure 1As shown in Figure 4: A marine cargo anti-tipping device includes a base 1. A support seat 3 81 from a connecting frame 8 is fixedly mounted on the base 1. The support seat 3 81 is rotatably connected to two symmetrically arranged connecting rods 82 via pins. The top ends of the connecting rods 82 are rotatably connected to the left and right sides of a cargo box bracket 6 via pins. An adjusting frame 2, a buffer support 3, and a controller 7 are mounted on the base 1. The adjusting frame 2 includes a support seat 1 21. A main shaft 22 is rotatably mounted on the support seat 1 21. A connecting arm 23, a winding wheel 1 26, and a winding wheel 27 are fixedly mounted on the main shaft 22. The winding wheel 1 26 and the winding wheel 27 respectively wind around one end of a connecting limiting steel cable 1 28 and a limiting steel cable 29. The limiting steel cable 1 28 and the limiting steel cable 29... The other end of the second steel cable 29 slides around the pulley 36 in the buffer support 3 and is respectively fixed to the left and right sides of the cargo box bracket 6. The connecting arm 23 is rotatably connected to one end of the hydraulic cylinder 24 through a pin. The other end of the hydraulic cylinder 24 is rotatably connected to the second support 25 through a pin. The second support 25 and the first support 21 are both fixed on the base 1. The cargo box bracket 6 includes a bracket frame 61. Side plates 63 are fixed on the left and right sides of the bracket frame 61. A monitoring module 67 is installed on the bracket frame 61. When the deck of the ship fixed to the base 1 tilts, the cargo box bracket 6 supporting the cargo box can monitor the levelness of the bottom of the cargo box in real time. The controller 7 controls the extension and retraction of the hydraulic cylinder 24 to drive the steel cable to wind up and down, thereby making the cargo box bracket 6 on the base 1. The main shaft rotates upwards, causing the cargo box bracket 6 to tend towards horizontality, preventing the cargo box from tipping over due to excessive tilt angle. The first winding wheel 26 and the second winding wheel 27 are of the same specification, and the first limiting steel cable 28 and the second limiting steel cable 29 are of the same length. The winding direction of the first limiting steel cable 28 on the first winding wheel 26 is opposite to the winding direction of the second limiting steel cable 29 on the second winding wheel 27. When the main shaft 22 rotates, it drives the first winding wheel 26 and the second winding wheel 27 to rotate synchronously, causing one of the limiting steel cables 28 and 29 to be wound up while the other is unwound by the same length, thus stably tightening and adjusting the left and right tilt angles of the cargo box bracket 6. The controller 7 includes a PLC, relays, and a solenoid valve for the hydraulic cylinder 24. C. Electrical connection monitoring module 67, the monitoring module 67 is a tilt sensor. The controller 7 can receive and process the left and right tilt angles of the cargo box bracket 6 fed back by the monitoring module 67, and then control the hydraulic cylinder 24 to extend and retract, driving the main shaft 22 to rotate, thereby winding and unwinding the steel cable, realizing the automatic adjustment of the angle of the cargo box bracket 6. The buffer support 3 includes a fixing block 31, the fixing block 31 is fixed on the base 1, the top of the fixing block 31 is fixed with a guide rod 32, the outer side of the guide rod 32 is slidably fitted with a slider 33, the top of the guide rod 32 is fixed with a limiting plate 35, the guide rod 32 between the limiting plate 35 and the slider 33 is slidably fitted with a spring 34, and the slider 33 is fixed with a pulley 36. When the ship experiences severe rocking,When the cargo box tilts rapidly to the left and right, one of the limiting cables 28 and 29 experiences a rapid increase in tension. At this time, the pulley 36 moves upward under the pull of the cable, and the spring 34 is compressed, creating elastic cushioning and effectively preventing damage or breakage of the cable under impact. Electrical limiting components 4 are installed on the lower left and right sides of the cargo box bracket 6. Each electrical limiting component 4 includes a support 41 fixed to the base 1. A micro switch 42 is fixed to the top of the support 41 and electrically connected to the controller 7. When one side of the cargo box bracket 6 presses against the contact of the micro switch 42, the controller 7 controls the hydraulic cylinder 24 to stop extending or retracting, preventing the cylinder 24 from exceeding its working stroke and being damaged. Limiting brackets 5 are fixed to the base 1 on both the front and rear sides of the electrical limiting component 4. The top of the limiting bracket 5 is connected to the micro switch... The tops of the base of the microswitch 42 are on the same plane. The limiting bracket 5 provides rigid support for the cargo box bracket 6 and prevents the base of the microswitch 42 from being damaged by compression. The cargo box bracket 6 includes a bracket frame 61. Connecting ears 66 are welded to both sides of the bracket frame 61 for fastening and connecting the first limiting steel cable 28 and the second limiting steel cable 29. Connecting ears 65 are also welded to both sides of the bracket frame 61. The first connecting ears 65 are rotatably connected to the connecting rod 82 via a pin. A support plate 62 is fixed to the top surface of the bracket frame 61. A reinforcing rib 64 is welded between the side plate 63 and the support plate 62. The bracket frame 61 provides stable support for the support plate 62, and the reinforcing rib 64 effectively improves the connection strength between the support plate 62 and the side plate 63, thus enabling the channel steel structure composed of the support plate 62 and the side plate 63 to stably support the cargo box.
[0035] The working principle of this technical solution is as follows: a crane is used to slowly lift the cargo box to be transported onto the pallet 62 of the cargo box bracket 6. After the cargo box is placed, the cargo box can be slightly fixed to the side plate 63 of the cargo box bracket by auxiliary binding straps, or the side plate 63 can be used to restrict the displacement of the cargo box in the left and right directions to complete the loading.
[0036] Real-time monitoring and adjustment during navigation: During ship navigation, the monitoring module 67, i.e., the tilt sensor, collects the levelness data of the cargo box bracket 6 in real time and transmits the tilt signal to the controller 7. When the ship's deck tilts, the cargo box bracket 6 tilts synchronously with the deck. The monitoring module 67 detects the tilt change and feeds it back to the controller 7. The PLC in the controller 7 quickly analyzes the data, calculates the angle value that needs to be adjusted, and then controls the solenoid valve of the hydraulic cylinder 24 to actuate, driving the hydraulic cylinder 24 to extend or retract: if the deck tilts to the left, the left side of the cargo box bracket lowers... When the deck tilts to the right, the controller 7 extends the hydraulic cylinder 24, pushing the connecting arm 23 to rotate the main shaft 22 clockwise. The first winding wheel 26 winds up the first limiting steel cable 28, and the second winding wheel 27 releases the second limiting steel cable 29. The right side of the cargo box bracket 6 rises under the pull of the steel cable, while the left side descends as the steel cable loosens, until the cargo box bracket 6 tends to be horizontal. Conversely, if the deck tilts to the right, the hydraulic cylinder 24 retracts, the main shaft 22 rotates counterclockwise, the second winding wheel 27 winds up the steel cable, and the first winding wheel 26 releases the steel cable, adjusting the cargo box bracket 6 to a horizontal state to ensure that the cargo box remains stable at all times.
[0037] During adjustment, if the tilt angle of the cargo container bracket 6 exceeds the preset range, such as due to excessive deck tilt caused by violent waves, one side of the cargo container bracket 6 will press the micro switch 42 of the electrical limit component 4. The controller 7 will immediately control the hydraulic cylinder 24 to stop extending and retracting, thus preventing damage to the hydraulic cylinder due to exceeding its working stroke. At the same time, the limit bracket 5 is flush with the base of the micro switch, which can form a rigid support for the cargo container bracket 6, preventing damage to the micro switch due to excessive compression. When the ship experiences violent rocking, the instantaneous impact force generated by the cargo container will cause the tension of the limit cable to increase sharply. The pulley 36 of the buffer support component 3 will be pulled by the cable, causing the slider 33 to move upward along the guide rod 32. The spring 34 will be compressed to generate elastic buffer, absorbing the impact force and preventing the cable from breaking or the cargo container bracket from being damaged.
