Description

Technical Field

[0001] The utility model belongs to the technical field of new energy ships, and more specifically, relates to a ship cargo lifting mechanism. Background Art

[0002] With the continuous development of green shipping, the various equipment and systems on board ships are becoming increasingly complex. Marine lifting equipment, a key tool for loading and unloading batteries on ships, is crucial for its safety and reliability in ship operations and cargo handling. During navigation, especially under complex and changing water conditions, the lifting equipment may slip due to the ship's swaying motion. This can not only damage the cargo but also pose a threat to the safety of the ship and personnel. Traditional marine lifting equipment typically utilizes mechanical or hydraulic drive systems, which have limitations in terms of stability and safety. Especially in situations of significant ship sway, traditional lifting equipment struggles to maintain stable lifting operations and is prone to slipping.

[0003] In the prior art, there is a technology named "A Hoisting Device for Battery Replacement of Electric Ships" and with a publication number of "CN221370251U". This technology relates to the technical field of battery replacement of electric ships, and more specifically, to a hoisting device for battery replacement of electric ships. It comprises two gantry poles, the tops of the two gantry poles are connected to the crossbeam, both ends of the crossbeam are connected to an extension assembly, the bottom ends of both sides of the crossbeam are connected to a reinforcement assembly, and the bottoms of the two gantry poles are connected to the horizontal adjustment assembly. The utility model uses the extension assembly to extend the two sides of the crossbeam, and at the same time uses the hoisting device starting assembly to drive the hoisting device body to slide to the outside of the ship's side, so as to clamp and transport the battery box placed on the dock. When the battery box passes through the gantry pole during hoisting, the battery box hoisted longitudinally is rotated 90 degrees in the horizontal direction, and the battery box passes through the gantry pole horizontally. After the battery box enters the inner edge of the gantry pole, it continues to rotate horizontally 90 degrees, and the battery box can be restored to the longitudinal hoisting and placed in the designated position.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in view of the deficiencies in the existing technology, a ship cargo lifting mechanism is provided which has a simple structure, can conveniently and reliably realize the lifting and transportation of the cargo to be lifted, and can automatically lock when the motor stops working, effectively preventing the lifting components from slipping due to shaking during the navigation of the ship, thereby improving the reliability and safety of the operation.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The utility model discloses a ship cargo lifting mechanism, wherein a traveling mechanism is arranged on the upper part of a supporting beam of a supporting frame, a traveling rack is provided on the supporting beam, a mechanism frame of the traveling mechanism is movably mounted on the supporting beam, a traveling drive motor is provided on the mechanism frame, a driving rod of the traveling drive motor is connected to a driving gear, the driving gear meshes with the traveling rack, and a lifting component is provided on the mechanism frame.

[0008] The support beam includes a first support beam and a second support beam, the driving gear includes a first driving gear and a second driving gear, the first driving gear is arranged at one end of the driving rod, and the second driving gear is arranged at the other end of the driving rod.

[0009] A plurality of driven gear sets are arranged on the mechanism frame, one driven gear of each driven gear set meshes with the travel rack on the first support beam, and another driven gear of each driven gear set meshes with the travel rack on the second support beam.

[0010] The first driving gear is engaged with one driven gear of a driven gear set, and the second driving gear is engaged with another driven gear of the driven gear set.

[0011] The hoisting component includes a hoisting and lifting drive motor, which is connected to a wire rope reel on which a wire rope is wound.

[0012] The steel wire rope is configured to be connected to a structure of cargo to be hoisted.

[0013] The hoisting and lifting drive motor driving gear 17 of the hoisting and lifting drive motor is engaged with the wire rope winding drum driven gear on the side of the wire rope winding drum.

[0014] The driving rod is connected to a position on one side of the mechanism frame through a first connecting seat near the first driving gear position, and is connected to a position on the other side of the mechanism frame through a second connecting seat near the second driving gear position.

[0015] A limiting roller is provided on each side of the mechanism frame. The limiting roller on one side of the mechanism frame fits the bottom surface of the first support beam, and the limiting roller on the other side of the mechanism frame fits the bottom surface of the second support beam.

[0016] The technical solution of this utility model is adopted, and the working principle and beneficial effects are as follows:

[0017] The present invention relates to a ship cargo lifting mechanism. The structure comprises a support frame disposed on a deck or other location on a ship where lifting operations are to be performed. A support beam is disposed above the support frame. A traveling mechanism is disposed above the supporting beam of the support frame. The traveling mechanism can advance or retreat along a track and in a direction defined by the supporting beam. A traveling rack is disposed on the supporting beam. A mechanism frame of the traveling mechanism is movably mounted on the supporting beam. A traveling drive motor is disposed on the mechanism frame. A driving rod of the traveling drive motor is connected to a driving gear that engages the traveling rack. A lifting component is disposed on the mechanism frame. Thus, the mechanism frame needs to advance or retreat along the supporting beam. The forward or backward movement is driven by the traveling drive motor. When the traveling drive motor rotates, the driving rod rotates. The driving gear at the end of the driving rod engages the traveling rack. Thus, the driving force is generated by the cooperation of the driving gear and rack, driving the traveling mechanism to move relative to the supporting beam. The forward or backward movement is controlled by the rotation direction of the traveling drive motor. The mechanism frame of the traveling mechanism is movably mounted on the supporting beam, defining the vertical position of the traveling frame and the supporting beam. When the driving gear rotates and applies an external force, the mechanism frame does not separate from the supporting beam. With the help of the gear rack structure, the gear rack can be locked with each other when the travel drive motor stops, achieving the purpose of self-locking, effectively preventing the lifting equipment from slipping due to shaking during the ship's travel.

[0022] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0023] As attached Figure 1 , Attachment Figure 2 As shown, the present invention is a ship cargo lifting mechanism. A traveling mechanism is disposed above a support beam 1 of a support frame. A traveling rack 2 is mounted on the support beam 1. A mechanism frame 3 of the traveling mechanism is movably mounted on the support beam 1. A traveling drive motor 4 is mounted on the mechanism frame 3. A drive rod 5 of the traveling drive motor 4 is connected to a drive gear 6, which engages the traveling rack 2. A lifting component 8 is mounted on the mechanism frame 3. The above structure addresses the shortcomings of the prior art and provides an improved technical solution. When the structure is set up, a support frame is set up on the deck or other parts of the ship where lifting operations need to be carried out, and a support beam is set on the upper part of the support frame. A walking mechanism is arranged on the upper part of the support beam 1 of the support frame. The walking mechanism can move forward or backward along the track and direction defined by the support beam 1. A walking rack 2 is set on the support beam 1, and a mechanism frame 3 of the walking mechanism is movably mounted on the support beam 1. A walking drive motor 4 is set on the mechanism frame 3, and a driving rod 5 of the walking drive motor 4 is connected to a driving gear 6, which engages the walking rack 2. A lifting component 8 is set on the mechanism frame 3. In this way, the mechanism frame 3 needs to move forward or backward along the support beam 1, and the power for moving forward or backward comes from the walking drive motor 4. When the walking drive motor 4 rotates, it drives the driving rod 5 to rotate, and the driving gear 6 at the end of the driving rod 5 engages the walking rack 2, thereby relying on the cooperation of the driving gear and rack to generate walking power, driving the walking mechanism to move relative to the support beam 1, and the control of moving forward or backward depends on the rotation direction of the walking drive motor 4. The frame 3 of the traveling mechanism is movably mounted on the support beam 1, so that the upper and lower positions of the traveling frame 3 and the support beam 1 are limited, and the frame 3 will not separate from the support beam 1 when the driving gear 6 rotates and applies external force. With the help of the rack and pinion structure, the rack and pinion are locked with each other when the traveling drive motor stops, achieving the purpose of self-locking, and preventing the lifting equipment from slipping due to shaking during the ship's travel. The ship cargo lifting mechanism described in the utility model has a simple structure, can conveniently and reliably realize the lifting and transportation of the cargo to be lifted, and can automatically lock when the motor stops working, effectively preventing the lifting components from slipping due to shaking during the ship's travel, thereby improving operational reliability and safety.

[0024] The support beam 1 comprises a first support beam 9 and a second support beam 10, and the drive gear 6 comprises a first drive gear 11 and a second drive gear 12. The first drive gear 11 is provided at one end of the drive rod 5, and the second drive gear 12 is provided at the other end. In this structure, the two support beams cooperate with the framework supporting the travel mechanism, ensuring the stability of the travel mechanism's load-bearing capacity. The same travel drive motor 4, via the drive rod 5, controls the synchronous operation of the two drive gears, thereby ensuring the stability of the travel mechanism as it travels along the two support beams 1 and ensuring safe lifting.

[0025] The mechanism frame 3 is provided with multiple driven gear sets. One driven gear 13 of each driven gear set engages the travel rack 2 on the first support beam 9, and another driven gear 13 of each driven gear set engages the travel rack 2 on the second support beam 10. In this structure, the driven gears cooperate with the support mechanism frame, enabling the mechanism frame to move flexibly relative to the travel rack.

[0026] The first driving gear 11 meshes with one driven gear 13 of a driven gear set, and the second driving gear 12 meshes with another driven gear 13 of a driven gear set. In the above structure, the driven gears on both sides support the mechanism frame from both sides to ensure the stable running of the mechanism frame.

[0027] The hoisting assembly 8 includes a hoisting and lifting drive motor 14, which is connected to a wire rope reel 15 on which a wire rope is wound. The wire rope is configured to connect to a load 16 to be hoisted. A hoisting and lifting drive motor drive gear 17 of the hoisting and lifting drive motor 14 engages a wire rope reel driven gear 18 on the side of the wire rope reel 15. With this structure, the rotation of the hoisting and lifting drive motor 14 drives the wire rope reel 15 to rotate, releasing or reeling in the wire rope, thereby facilitating the hoisting of the load.

[0028] The driving rod 5 is connected to one side of the mechanism frame 3 via a first connecting seat 19 near the first driving gear 11, and is connected to the other side of the mechanism frame 3 via a second connecting seat 20 near the second driving gear 12. With the above structure, the first connecting seat and the second connecting seat can reliably limit the driving rod, ensuring that the driving rod can only rotate and cannot move.

[0029] A limiting roller is provided on each side of the mechanism frame 3. The limiting roller on one side of the mechanism frame 3 contacts the bottom surface of the first support beam 9, while the limiting roller on the other side of the mechanism frame 3 contacts the bottom surface of the second support beam 10. With this structure, the limiting rollers ensure rolling contact between the bottom of the mechanism frame and the bottom surface of the support beam, thereby limiting the vertical position of the mechanism frame while preventing excessive friction.

[0030] The ship cargo lifting mechanism described in the present invention is structurally arranged, and a support frame is arranged on the deck or other parts of the ship where lifting operations need to be carried out. A support beam is arranged on the upper part of the support frame, and a walking mechanism is arranged on the upper part of the support beam 1 of the support frame. The walking mechanism can move forward or backward along the track and direction defined by the support beam 1, and a walking rack 2 is arranged on the support beam 1. The mechanism frame 3 of the walking mechanism is movably mounted on the support beam 1, and a walking drive motor 4 is arranged on the mechanism frame 3. The driving rod 5 of the walking drive motor 4 is connected to the driving gear 6, and the driving gear 6 engages the walking rack 2. A lifting component 8 is arranged on the mechanism frame 3. In this way, the mechanism frame 3 needs to move forward or backward along the support beam 1, and the power for moving forward or backward comes from the walking drive motor 4. When the walking drive motor 4 rotates, it drives the driving rod 5 to rotate, and the driving gear 6 at the end of the driving rod 5 engages the walking rack 2, thereby relying on the cooperation of the driving gear and rack to generate the walking power, driving the walking mechanism to move relative to the support beam 1, and the control of moving forward or backward depends on the rotation direction of the walking drive motor 4. The traveling mechanism's frame 3 is movably mounted on the support beam 1, defining the vertical position of the traveling mechanism 3 and the support beam 1. When the drive gear 6 rotates and applies external force, the frame 3 does not separate from the support beam 1. The rack and pinion structure engages the gears and pinions when the traveling drive motor stops, achieving a self-locking effect and effectively preventing the hoisting equipment from slipping due to shaking during ship travel.

[0031] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
