[0002] During the transportation of oil at sea, accidents may occur on tankers, requiring the quick and safe transfer of the injured from the deck or cargo hold to a safe area. Traditional methods of transferring the injured often rely on manual handling or simple stretchers, which are inefficient and risky. Although there are many types of rescue devices available, most of them are bulky and single, and the rescue height is limited, making them unsuitable for use in ship scenarios. For example, if a crew member is in distress or has an accident at the bottom of the oil tank, rescuers will not be able to quickly reach the bottom of the tank for rescue, which will delay the rescue time and cause injury or death to the crew member. Therefore, it is particularly important to design an efficient, safe, and automated device for transferring the injured. Summary of the Invention

Example 1

[0023] See also Figure 1-Figure 3 , Figure 1 A schematic structural diagram of the present invention is provided. As shown in the figure, the present invention relates to a casualty lifting device for ship rescue, comprising a pneumatically balanced lifting device and a triangular support frame. The pneumatically balanced lifting device is mounted on the triangular support frame. The pneumatically balanced lifting device comprises a pneumatic control system, an actuator cylinder, and a casualty receiving mechanism. The pneumatic control system is powered by an air source to control the telescopic movement of the actuator cylinder, thereby driving the casualty receiving mechanism to lift and transfer the casualty.

[0024] The pneumatic balancing lifting device is provided with a safety protection device, which includes overload protection, limit switch and emergency brake devices to ensure that the system can automatically monitor and respond to abnormal situations during operation to ensure the safety of the injured and equipment.

[0025] In this embodiment, the execution cylinder adopts a pneumatic winch 8, and the triangular support frame includes a top plate 1 and three telescopic support legs 2. The three telescopic support legs 2 are evenly arranged below the top plate 1. The top of the telescopic support leg 2 is connected to the bottom surface of the top plate 1. The telescopic support leg 2 includes two inner and outer square tubes that are sleeved and connected. The inner square tube is arranged below the outer square tube to achieve telescopic movement; the bottom end of the telescopic support leg 2 is provided with a support base 10.

[0026] A U-shaped plate 6 is clamped on the outer square tube of one of the telescopic supporting legs 2 , a winch mounting plate 7 is arranged on the U-shaped plate 6 , and a pneumatic winch 8 is arranged on the winch mounting plate 7 .

[0027] A head pulley 3 is provided below the top plate 1, and the head pulley 3 is connected to the bottom surface of the top plate 1 through a connecting piece; a steel wire rope 5 is wound around the head pulley 3, one end of the steel wire rope 5 is connected to a hook 4, and the other end is connected to a pneumatic winch 8; the hook 4 is used to lift the wounded accommodation mechanism.

[0028] A connecting chain 9 is provided between adjacent telescopic supporting legs 2 .

[0029] In this embodiment, the wounded receiving mechanism may be a clamp or a portable stretcher.

[0030] The utility model provides a wounded person lifting device for ship rescue, and the installation steps are as follows:

[0031] 1. Determine the location of the manhole cover or cargo tank: Determine the installation location of the pneumatically driven casualty lift system based on the layout of the tanker deck or cargo hold and the casualty transfer requirements. The lift is portable, with an aluminum tripod and a detachable, portable pneumatic motor.

[0032] 2. Install the support structure: Install the support structure at the selected installation location and ensure it is stable and reliable.

[0033] 3. Install the pneumatic balance crane device: Fix the pneumatic tripod crane device on the deck and connect the pneumatic control system, actuator cylinder and other components.

[0034] 4. Debug the system: Debug and test the system according to the operating procedures to ensure that all its functions are normal, safe and reliable.

[0035] Before operation, the system should be thoroughly inspected to ensure that all components are intact and securely connected; when lifting the injured, smooth operation should be maintained to avoid sudden acceleration or deceleration that may cause discomfort or injury to the injured.

[0036] Working principle:

[0037] This utility model provides a casualty lifting device for shipboard rescue operations. Under normal air supply conditions, a pneumatic control system controls the extension and retraction of an actuator cylinder. When a casualty needs to be lifted, the operator activates the system by controlling the pneumatic cherry air device. The actuator cylinder extends, driving a clamp or portable stretcher to contact and secure the casualty. Subsequently, the control device is further operated to retract the actuator cylinder, smoothly lifting the casualty and transferring them to a safe area on the deck. Throughout this process, rescuers monitor the system's operating status in real time and automatically initiate protective measures if an abnormality occurs.

[0038] Since the deck surfaces of oil tankers are all dangerous areas, electric small crane winches cannot be used, and manual winches are unable to provide rapid rescue, the utility model adopts a pneumatically driven lifting mechanism.

[0039] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
