Description

Technical Field

[0001] This invention relates to the field of transportation loading equipment technology, specifically to a suction-type transfer equipment for transferring cargo from small boats to large ships, which is particularly suitable for scenarios where cargo from small boats is transferred to the cargo hold of large ships without an intermediate platform. Background Technology

[0002] In the maritime transport sector, cargo transshipment is a common process in ports, anchorages, and offshore operations. Transferring cargo from the holds of smaller vessels to those of larger ships typically requires lifting, grabbing, or conveying equipment. This transshipment equipment generally needs to possess functions such as support, lifting or suction conveying, position adjustment, and control to adapt to different vessel positions, hold locations, and cargo types.

[0003] Currently, the relevant technologies mainly rely on grabbers or excavators on intermediate platforms to transfer cargo from small boats to large vessels. That is, an intermediate platform is set up between the large and small boats, and then grabbers or excavators are used to grab the cargo from the small boats and place it into the cargo hold of the large vessel. This method is more common when intermediate platforms or shore-based lifting facilities are available.

[0004] However, existing technologies have the following shortcomings: when there is no intermediate platform at the work site, the grab crane or excavator cannot be set up, thus preventing the transfer operation from being completed, which severely restricts the transfer operation and reduces efficiency; at the same time, the construction and dismantling of the intermediate platform is costly, and the transfer position adjustment is inflexible. Therefore, there is a need for a transfer equipment that does not rely on an intermediate platform, is easy to install and dismantle, can flexibly adjust the transfer position, and provides stable support, in order to solve the above-mentioned technical problems.

[0052] Please see Figure 14 In some embodiments, multiple transshipment devices of the present invention can be deployed on a large ship to cover different cargo hold areas. Please refer to [link to relevant documentation]. Figure 15 During operation, the suction pipe 60 extends into the cargo hold of the small boat. After the suction motor 50 is started, it generates negative pressure or suction, which transports the goods through the suction pipe 60, the suction motor 50, and the delivery pipe 70 to the cargo hold of the large ship. The fixed end 80 of the delivery pipe is located in the cargo hold of the large ship, and the frame cover 81 can reduce dust escaping.

[0053] Please see Figure 16 The translation method of the suction motor 50 is as follows: Forward movement: The first thin rod 11 of the first hydraulic telescopic rod 10 and the second thin rod 21 of the second hydraulic telescopic rod 20 simultaneously extend by a certain length. The amount of extension is determined by the difference in side length of the triangle formed by the different positions of the suction motor 50. The extension is driven by the increase in oil volume in the first thick rod 12 and the second thick rod 22. Forward movement is defined as follows: the distance between the position after forward movement and the line connecting the two fixed seats 30 is greater than the distance between the position before forward movement and the line connecting the two fixed seats 30, and the line connecting the position after forward movement and the position before forward movement is perpendicular to the line connecting the two fixed seats 30.

[0054] Reverse movement: The first thin rod 11 of the first hydraulic telescopic rod 10 and the second thin rod 21 of the second hydraulic telescopic rod 20 simultaneously shorten by a certain length. The amount of shortening is determined by the difference in side length of the triangle formed by the different positions of the suction motor 50. The shortening is driven by the reduction in the amount of oil in the first thick rod 12 and the second thick rod 22. Reverse movement is defined as follows: the distance between the position after the reverse movement and the line connecting the two fixed seats 30 is less than the distance between the position before the reverse movement and the line connecting the two fixed seats 30, and the line connecting the position after the reverse movement and the position before the reverse movement is perpendicular to the line connecting the two fixed seats 30.

[0055] Leftward movement: The first thin rod 11 of the first hydraulic telescopic rod 10 and the second thin rod 21 of the second hydraulic telescopic rod 20 simultaneously change by a certain length. The amount of change is determined by the difference in side length of the triangle formed by the different positions of the suction motor 50. The change is driven by the change in the amount of oil in the first thick rod 12 and the second thick rod 22. Leftward movement is defined as follows: the position after leftward movement is to the left of the position before leftward movement, and the line connecting the position after leftward movement and the position before leftward movement is parallel to the line connecting the two fixed seats 30.

[0056] Rightward movement: The first thin rod 11 of the first hydraulic telescopic rod 10 and the second thin rod 21 of the second hydraulic telescopic rod 20 simultaneously change by a certain length. The amount of change is determined by the difference in the side length of the triangle formed by the different positions of the suction motor 50. The change is driven by the change in the amount of oil in the first thick rod 12 and the second thick rod 22. Rightward movement is defined as: the position after rightward movement is to the right of the position before rightward movement, and the line connecting the position after rightward movement and the position before rightward movement is parallel to the line connecting the two fixed seats 30.

[0057] In some embodiments, the suction motor 50 can be replaced with other negative pressure suction devices or vacuum conveying devices; the hydraulic telescopic rod can be replaced with an electric push rod, a pneumatic telescopic cylinder, or a screw telescopic mechanism. The mounting base can also be other structures that provide a rotatable connection and can be installed with the hull. The material and diameter of the suction pipe 60 and the delivery pipe 70 can be selected according to the type of cargo. The control console 90 can be wired or wirelessly controlled.

[0058] Through the above-described structural design, this invention enables the transfer of cargo from small boats to large vessels without the need for an intermediate platform; the suction motor moves forward, backward, left, and right by synchronous or differential changes in the length of two hydraulic telescopic rods; the fixed base, telescopic arm, and mounting base form a stable support, facilitating installation and disassembly and effectively improving transfer efficiency.
