Description

Technical Field

[0001] This utility model relates to the field of ship cargo transfer equipment technology, and in particular to an auxiliary unloading device for ships. Background Technology

[0002] During ship unloading operations, cargo that is inside the ship's hold or on the deck needs to be transferred to the dock or other means of transport.

[0003] However, in the existing technology, traditional unloading methods mostly rely on manual handling or simple lifting equipment. Manual handling is not only labor-intensive and has extremely low unloading efficiency, but also prone to accidents such as cargo falling or personnel injury when the cargo is heavy or the ship deck is tilted. Existing simple lifting equipment usually only has a single lifting or moving function and lacks a stable cargo clamping structure. When transferring irregular or easily sliding cargo, the cargo is prone to shifting or falling off. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of high labor intensity, low efficiency, unstable cargo clamping and lack of safety protection in the existing technology of ship unloading, and to propose an auxiliary unloading device for ships.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary unloading device for ships, comprising a moving mechanism and a clamping mechanism. The moving mechanism includes a first frame, a positioning block, a connecting plate, and a rope. One end of the rope is fixedly connected to the first frame. A first fixed pulley is rotatably mounted on the upper surface of the connecting plate, and the first fixed pulley overlaps the surface of the rope. The positioning block is fixedly mounted in the middle section of the top of the first frame. A second fixed pulley is fixedly mounted on one end of the first frame and the bottom of the positioning block. The rope overlaps the pulley surface of the second fixed pulley. The clamping mechanism includes a support frame, which is bolted to the lower surface of the connecting plate. The other end of the rope is fixedly connected to a take-up roller. A positioning frame is fixedly mounted on one side of the first frame, and the take-up roller is rotatably mounted inside the positioning frame.

[0006] Preferably, a reinforcing bracket is fixedly installed at the junction of the first frame and the rope, and the reinforcing bracket is fixedly connected to the other end of the first frame.

[0007] Preferably, a drive gear is rotatably mounted on the inner side of the positioning frame, and a driven gear is fixedly mounted on one end of the take-up roller, the driven gear meshing with the drive gear.

[0008] Preferably, a blocking gear is rotatably mounted on the bottom of the positioning frame, and the blocking gear meshes with the driving gear.

[0009] Preferably, a first electric cylinder is rotatably mounted on the upper surface of the support frame, and one end of the piston rod of the first electric cylinder is rotatably connected to a transmission rod.

[0010] Preferably, one end of the transmission rod is fixedly connected to a limit rod, and the end of the limit rod is fixedly connected to a gripper assembly.

[0011] Preferably, a second electric cylinder is fixedly installed on the inner side of the support frame, and one end of the piston rod of the second electric cylinder is fixedly connected to the top plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting the moving mechanism and the clamping mechanism to work together, and with the guiding effect of the first fixed pulley and the second fixed pulley, the stable lifting and moving of goods is achieved, which effectively solves the problem of unstable goods clamping in existing equipment. At the same time, it reduces the intensity of manual labor and improves unloading efficiency. By setting a reinforcing bracket at the junction of the first frame and the rope, the overall structural stability is enhanced and the loosening of component connections is prevented. The cooperation of the first fixed pulley and the second fixed pulley reduces the frictional resistance of the rope movement and improves the smoothness of lifting. Compared with the prior art, it significantly improves the safety of the unloading process and the stability of equipment operation.

[0013] 2. In this utility model, a blocking gear is set at the bottom of the positioning frame to mesh with the driving gear, which can limit the reverse rotation of the driving gear and prevent the rope from accidentally loosening and falling when the goods are suspended in the air. The clamping mechanism controls the opening and closing of the gripper assembly through the first electric cylinder, transmission rod and limit rod, and combined with the second electric cylinder to push the top plate to assist in fixing, forming a multi-directional clamping structure, which effectively solves the problem of unstable goods clamping in existing equipment.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an auxiliary unloading device for ships, including a moving mechanism 1 and a clamping mechanism 2. The moving mechanism 1 includes a first frame 11, a positioning block 12, a connecting plate 14, and a rope 16. One end of the rope 16 is fixedly connected to the first frame 11. A first fixed pulley 15 is rotatably mounted on the upper surface of the connecting plate 14, and the first fixed pulley 15 overlaps the surface of the rope 16. The positioning block 12 is fixedly installed in the middle section of the top of the first frame 11. A second fixed pulley 17 is fixedly installed at one end of the moving mechanism 1 and at the bottom of the positioning block 12. The rope 16 overlaps the pulley surface of the second fixed pulley 17. The clamping mechanism 2 includes a support frame 21, which is connected by screws. A bolt is installed on the lower surface of the connecting plate 14. The other end of the rope 16 is fixedly connected to a take-up roller 19. A positioning frame 18 is fixedly installed on one side of the first frame 11. The take-up roller 19 is rotatably installed inside the positioning frame 18. A reinforcing bracket 13 is fixedly installed at the junction of the first frame 11 and the rope 16. The reinforcing bracket 13 is fixedly connected to the other end of the first frame 11. A drive gear 111 is rotatably installed on the inner side of the positioning frame 18. A driven gear 110 is fixedly installed on one end of the take-up roller 19. The driven gear 110 meshes with the drive gear 111. A blocking gear 112 is rotatably installed on the bottom of the positioning frame 18. The blocking gear 112 meshes with the drive gear 111.

[0019] The specific setup and function of this embodiment are described in detail below. The first frame 11 provides basic support for the moving mechanism 1. The reinforcing bracket 13 is fixedly installed at the junction of the first frame 11 and the rope 16 and is fixedly connected to the other end of the first frame 11 to enhance the stability of the connection between the first frame 11 and the rope 16. The positioning block 12 is fixed to the middle of the top of the first frame 11. The second fixed pulley 17 is fixedly installed at one end of the first frame 11 and the bottom of the positioning block 12. The first fixed pulley 15 is rotatably installed on the upper surface of the connecting plate 14. The rope 16 overlaps the second fixed pulley 17 and changes its direction. The first fixed pulley 15 overlaps... On the rope 16, the other end of which is fixedly connected to the take-up roller 19 rotatably mounted inside the positioning frame 18. The driven gear 110 fixedly mounted on one end of the take-up roller 19 meshes with the driving gear 111. During operation, the driving gear 111 rotates, driving the driven gear 110 to rotate, causing the take-up roller 19 to wind up or release the rope 16. The winding of the rope 16 will lift the first fixed pulley 15 and drive the connecting plate 14 and the clamping mechanism 2 connected to it to move. The blocking gear 112 is specifically a sector gear, and its edge is provided with an extension. After the height of the clamping mechanism 2 is determined, the extension is pushed upward to make the blocking gear 112 meshes with the drive gear 111, preventing it from rotating in the opposite direction and ensuring the stability of the rope 16's winding state. Finally, the moving mechanism 1 can be directly pushed to complete the movement and transfer of cargo during the ship unloading process. When it is necessary to release the rope 16, the extension is pushed downwards to disengage the teeth of the blocking gear 112 from the drive gear 111, thereby releasing the winding roller 19. By setting the moving mechanism 1 and the clamping mechanism 2, stable movement and clamping of cargo during ship unloading are achieved. The cooperation of the first fixed pulley 15 and the second fixed pulley 17 reduces the frictional resistance of the rope 16 during movement, improving the smoothness of cargo movement. The reinforcing bracket 13 strengthens the... The structural stability of the connection between the first frame 11 and the rope 16 avoids safety hazards caused by loose connections of components during unloading. The meshing transmission between the drive gear 111 and the driven gear 110 makes the winding roller 19 more precise in winding or releasing the rope 16, which facilitates control of the speed and position of cargo movement. The reverse restriction of the blocking gear 112 on the drive gear 111 prevents cargo from falling due to accidental loosening of the rope 16 during movement, thus improving unloading safety. The entire device effectively improves the efficiency of ship unloading, reduces the labor intensity of manual unloading, and ensures the safety of cargo and operators during unloading.

[0020] Example 2: Figure 1 , Figure 2 and Figure 4As shown, a first electric cylinder 22 is rotatably mounted on the upper surface of the support frame 21. One end of the piston rod of the first electric cylinder 22 is rotatably connected to a transmission rod 26. One end of the transmission rod 26 is fixedly connected to a limit rod 27. The end of the limit rod 27 is fixedly connected to a gripper assembly 23. A second electric cylinder 24 is fixedly mounted on the inner side of the support frame 21. One end of the piston rod of the second electric cylinder 24 is fixedly connected to a top plate 25.

[0021] The overall effect of this embodiment is as follows: during operation, the extension and retraction of the piston rod of the first electric cylinder 22 drives the transmission rod 26 to rotate. The transmission rod 26 drives the gripper assembly 23 to open and close through the limiting rod 27, thereby clamping and releasing the goods. At the same time, the extension and retraction of the piston rod of the second electric cylinder 24 can push the top plate 25 to move. The top plate 25 can assist in pressing the goods downward from the top of the goods. Together with the gripper assembly 23, it further improves the stability of the goods clamping and ensures that the goods are not easily deviated or fall off during the process of the moving mechanism 1 driving the clamping mechanism 2 to transfer the goods. Through the cooperation of the first electric cylinder 22, the transmission rod 26, the limiting rod 27 and the gripper assembly 23, the goods are clamped, reducing labor intensity. The limiting rod 27 determines the rotation center of the gripper assembly 23, ensuring the stability of the gripper assembly 23. The setting of the second electric cylinder 24 and the top plate 25 can assist in fixing the goods from the side. Together with the gripper assembly 23, it forms a multi-directional clamping, improving the adaptability and clamping stability of goods of different shapes and sizes.

[0022] The usage and working principle of this device are as follows: First, place the first frame 11 of the moving mechanism 1 in a suitable position, ensuring that the blocking gear 112 is initially separated from the driving gear 111. Then, place the goods to be unloaded between the gripper assemblies 23. Activate the first electric cylinder 22 on the upper surface of the support frame 21, causing the piston rod of the first electric cylinder 22 to extend, driving the transmission rod 26 to open the gripper assembly 23. Then, reverse the operation of the first electric cylinder 22 to close the gripper assembly 23 and clamp the goods. Subsequently, activate the second electric cylinder 24 inside the support frame 21, causing the piston rod of the second electric cylinder 24 to extend, pushing the top plate 25 to contact the goods and assist in fixing them. Afterward, rotate the driving gear 111 inside the positioning frame 18. The driving gear 111 drives the driven gear 110 meshing with it to rotate. The driven gear 110 drives the winding roller 19 to rotate, and the winding roller 19 winds up the rope 16. The winding of the rope 16 raises the first fixed pulley 15, driving the connecting plate... The connecting plate 14 and the clamping mechanism 2 connected to it by bolts rise together with the goods. When the goods rise to a suitable height, the drive gear 111 stops rotating, and the blocking gear 112 at the bottom of the positioning frame 18 is rotated to mesh with the drive gear 111, restricting the reverse rotation of the drive gear 111. Then, the first frame 11 of the moving mechanism 1 is pushed to transfer the goods to the designated unloading position. After reaching the position, the blocking gear 112 is rotated in the reverse direction to separate it from the drive gear 111. Then, the drive gear 111 is rotated in the reverse direction to drive the driven gear 110 and the winding roller 19 to rotate in the opposite direction, releasing the rope 16, so that the connecting plate 14, the clamping mechanism 2 and the goods fall together to a suitable height. Finally, the second electric cylinder 24 is operated first to retract the piston rod of the second electric cylinder 24, which drives the top plate 25 to separate from the goods. Then, the first electric cylinder 22 is operated to open the gripper assembly 23 to unload the goods, completing one unloading operation. If it is necessary to continue unloading, the above clamping, moving and releasing steps can be repeated.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
