Description

Technical Field

[0001] This utility model relates to the technical field of automatic water supply devices, specifically to an automatic water supply device for a ship unloader's water tank. Background Technology

[0002] In cargo unloading operations at port terminals, ship unloaders are key pieces of equipment, and their stable operation depends on a sufficient water supply in the water tank. The water in the tank is mainly used for equipment cooling and dust suppression during the operation of the ship unloader, playing an important role in ensuring the normal operation of the ship unloader and improving the working environment.

[0003] Currently, when the water tank of the ship unloader needs to be replenished, the usual method is to manually connect the connector on the ship unloader to the connector of the water source. After the water tank is replenished, the two connectors are then manually separated.

[0004] However, the existing water replenishment method has drawbacks: the ship unloader is large and operates in a complex environment. When manually connecting the two joints, not only do workers need to operate from specific positions, but misalignment is also prone to occur during the connection process, making the connection operation inconvenient. This not only increases the labor intensity of the workers and prolongs the water replenishment time, but also affects the operating efficiency of the ship unloader. Utility Model Content

[0019] Optionally, the under-machine docking mechanism further includes:

[0020] A fixed bracket, which is installed on the ground;

[0021] The machine-mounted adjustment assembly is mounted on the fixed bracket, and the male connector is mounted on the movable end of the machine-mounted adjustment assembly. The machine-mounted adjustment assembly can drive the male connector to move.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0042] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0043] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] In terms of equipment cooling, the water in the unloader's water tank can dissipate heat for core components such as the drive motor and gearbox, ensuring stable operation of the equipment. In terms of dust suppression, the water in the unloader's water tank can also reduce dust during the unloading of bulk cargo by spraying water, thus improving the working environment.

[0048] like Figures 1-7 As shown, it illustrates an automatic water supply device for a ship unloader water tank according to an embodiment of the present invention, used to add water to the ship unloader water tank, including an on-machine docking mechanism 1 installed on the ship unloader and an under-machine docking mechanism 2 installed on the ground and connected to a water source; the on-machine docking mechanism 1 includes an on-machine adjustment component 11 and a docking female head 12, and the on-machine adjustment component 11 is installed on the ship unloader.

[0049] Specifically, the onboard adjustment assembly 11 adopts a multi-degree-of-freedom structure. A docking female head 12 is installed at the movable end of the onboard adjustment assembly 11. The interface of the docking female head 12 is concave, and the docking female head 12 is connected to the unloader's water tank via a pipe. The offboard docking mechanism 2 is fixed to the ground. The interface of the docking male head 21 is convex, matching the docking female head 12. One end of the docking male head 21 is connected to a ground water source via a pipe. A positioning signal transmitter 13 is installed at the end of the onboard adjustment assembly 11, and a positioning signal receiver 22 is installed at a corresponding position on the offboard docking mechanism 2. After the positioning signal receiver 22 aligns with the positioning signal transmitter 13, the onboard adjustment assembly 11 can push the docking female head 12 to move, thereby connecting the docking female head 12 with the docking male head 21.

[0050] When the unloader's water tank needs replenishment, the unloader moves to the replenishment area. The onboard adjustment component 11 pushes the docking female head 12 forward or backward to a position coaxial with the docking male head 21. Then, the positioning signal transmitter 13 sends a signal, and the positioning signal receiver 22 of the docking mechanism 2 receives the signal. After confirming that the docking male head 21 and the docking female head 12 are coaxial, the onboard adjustment component 11 moves forward to push the docking female head 12 toward the docking male head 21, so that the docking female head 12 and the docking male head 21 are connected. At this time, water from the water source enters the unloader's water tank through the docking male head 21 and the docking female head 12. After replenishment is completed, the onboard adjustment component 11 drives the docking female head 12 to move in the opposite direction, separating the two.

[0051] Automatic docking of the joints is achieved, eliminating the need for manual operation and reducing the labor intensity of workers. The cooperation of the positioning signal transmitter 13 and the positioning signal receiver 22 solves the problem of inaccurate alignment during manual docking, making the docking operation more convenient, shortening the water replenishment time, and improving the operating efficiency of the unloader.

[0052] For example, such as Figure 2As shown, in some examples, a first flange 121 is fixed to the end of the mating head 12. Multiple mounting rods 14 are distributed along the circumferential direction on the edge of the first flange 121. Each mounting rod 14 is fitted with a spring as an elastic element 141. The fixing plate 15 is a circular or square plate. Multiple mounting holes 1501 are opened on the fixing plate 15 corresponding to the positions of the mounting rods 14. The fixing plate 15 is slidably fitted onto the end of the mounting rod 14 away from the first flange 121 through the mounting holes 1501. One side of the fixing plate 15 is connected to the movable end of the machine adjustment assembly 11.

[0053] When docking is required, the unloader moves to the water replenishment area. The onboard adjustment component 11 pushes the docking female head 12 forward or backward to a position coaxial with the docking male head 21. Then, the positioning signal transmitter 13 sends a signal, and the positioning signal receiver 22 of the docking mechanism 2 receives the signal. After confirming that the docking male head 21 and the docking female head 12 are coaxial, the onboard adjustment component 11 pushes the fixing plate 15 forward, so that the fixing plate 15 drives the mounting rod 14 to push the docking female head 12 forward until the docking female head 12 contacts the docking male head 21. The onboard adjustment component 11 continues to push the fixing plate 15 forward, so that the fixing plate 15 moves along the mounting rod 14 toward the docking female head 12. During the movement, the fixing plate 15 squeezes the spring on the mounting rod 14. The spring is compressed and generates elastic force, which pushes the docking female head 12 to press against the docking male head 21, so that the docking female head 12 and the docking male head 21 are tightly abutted.

[0054] The elastic element 141 acts as a buffer during the clamping process, preventing hard contact between the female connector 12 and the male connector 21, reducing wear on components, and extending the service life of the device. Simultaneously, by pressing the elastic element 141 with the fixing plate 15, sufficient contact force between the female connector 12 and the male connector 21 is ensured, guaranteeing a tight seal.

[0055] For example, such as Figure 2 As shown, in some examples, a sensing plate 16 is fixed on the first flange 121, and a contact position sensor 151 is installed on the side of the fixing plate 15 facing the docking female head 12. The sensing plate 16 and the position sensor 151 are on the same horizontal line and their positions correspond to each other.

[0056] It should be noted that during the process of the machine-mounted adjustment assembly 11 pushing the fixed plate 15 to move, the female connector 12 is pressed against the male connector 21 by the spring force. After the female connector 12 and the male connector 21 are pressed together, the sensing plate 16 on the female connector 12 comes into contact with the position sensor 151 on the fixed plate 15. The position sensor 151 sends a signal to control the machine-mounted adjustment assembly 11 to stop pushing the fixed plate 15. The setting of the sensing plate 16 and the position sensor 151 can control the degree of pressing between the female connector 12 and the male connector 21, avoiding the problem of damage to components caused by excessive pushing by the machine-mounted adjustment assembly 11, and improving the accuracy and reliability of docking.

[0057] For example, such as Figure 4 and Figure 6 As shown, in some examples, the onboard adjustment assembly 11 includes a mounting frame 111, an actuator 112, and a push rod 113. The mounting frame 111 is a steel frame fixed to the ship unloader. A hydraulic cylinder is mounted on the mounting frame 111 as the actuator 112. The push rod 113 is the piston rod of the hydraulic cylinder. The end of the push rod 113 is fixedly connected to the fixing plate 15 by bolts.

[0058] Specifically, when docking is required, the hydraulic cylinder drives the piston rod to extend, causing the push rod 113 to move forward. The push rod 113 pushes the fixing plate 15 to slide along the mounting rod 14, compressing the spring and allowing the docking female head 12 to insert into the docking male head 21. When docking is complete and water replenishment is finished, the piston rod of the hydraulic cylinder retracts, causing the push rod 113 and the fixing plate 15 to move in the opposite direction. The spring returns to its original state, and the docking female head 12 separates from the docking male head 21. Using a hydraulic cylinder as the actuator 112 provides a large and stable driving force, ensuring sufficient insertion force between the docking female head 12 and the docking male head 21, ensuring a firm docking. At the same time, the linear movement of the push rod 113 makes the docking process smoother and more reliable.

[0059] For example, such as Figure 5 As shown, in some examples, the fixed bracket 23 is a frame structure fixed to the ground, the under-machine adjustment component 24 is mounted on the fixed bracket 23, and the male connector 21 is fixed on the under-machine adjustment component 24.

[0060] The under-machine adjustment component 24 can adjust the position of the docking male head 21 so that the docking male head 21 can adapt to the height of different ship unloaders, pushers or reclaimers. The position of the docking male head 21 can be adjusted according to the height of the ship unloader, pusher or reclaimer, so that the under-machine docking mechanism 2 can be adapted to the water replenishment needs of different equipment in different positions and states.

[0061] For example, such as Figure 5 and Figure 6As shown, in some examples, the mounting bracket 111 is provided with a first water supply pipe 3, the docking female head 12 is connected to the unloader water tank through the first water supply pipe 3, and the fixed bracket 23 is provided with a second water supply pipe 4, the docking male head 21 is connected to the ground water source through the second water supply pipe 4.

[0062] The first water supply pipe 3 uses a combination of high-strength plastic flexible hose and metal rigid pipe for connection. The flexible hose section of the first water supply pipe 3 is connected to the female connector 12, and the rigid pipe section of the first water supply pipe 3 is connected to the water inlet of the unloader's water tank. The second water supply pipe 4 also uses a combination of high-strength plastic flexible hose and metal rigid pipe for connection. The flexible hose section of the second water supply pipe 4 is welded to the male connector 21, and the rigid pipe section of the second water supply pipe 4 is connected to the outlet pipe of the surface water source through multiple flanges. It should be noted that the flexible hose sections and rigid pipe sections of both the first water supply pipe 3 and the second water supply pipe 4 are connected by flanges.

[0063] It should be noted that after the docking female head 12 and docking male head 21 are connected, water from the ground water source flows into the docking male head 21 through the second water supply pipe 4, then enters the first water supply pipe 3 through the docking female head 12, and finally flows into the unloader water tank through the first water supply pipe 3, completing the water replenishment process.

[0064] Both the first water inlet pipe 3 and the second water inlet pipe 4 use a combination of flexible and rigid pipe sections to adapt to the movement of the machine's adjustment components 11 and avoid pipe damage. At the same time, they ensure the stability of the connection with the ground water source. The combination of the two ensures the smooth flow of water and realizes the delivery of water from the source to the water tank.

[0065] For example, such as Figure 6 As shown, in some examples, the check valve 31 is a one-way valve, installed on the first water supply pipe 3 near the unloader's water tank, with its flow direction consistent with the direction in which water enters the tank. Specifically, when water is replenished, the water, under pressure, pushes open the valve core of the check valve 31 and flows smoothly into the unloader's water tank. When water replenishment stops or a drop in water pressure occurs, the valve core closes, preventing water in the first water supply pipe 3 from flowing back to the docking connector 12. This prevents water in the unloader's water tank from flowing back through the first water supply pipe 3, ensuring the water volume in the tank and also preventing impact damage to the docking connector 12 caused by backflow.

[0066] For example, such as Figure 5 As shown, in some examples, the automatic water supply valve 25 is an electrically controlled valve, installed on the second water supply pipe 4 near the ground water source. When the unloader's water tank needs replenishment, the control system sends a signal, and the automatic water supply valve 25 opens, allowing water from the source to enter the male connector 21 through the second water supply pipe 4. When the water tank is fully replenished, the control system sends a shutdown signal, and the automatic water supply valve 25 closes, cutting off the water supply.

[0067] It achieves automatic opening and closing control of the water source, eliminating the need for manual valve operation and further improving the automation level of the water replenishment process. Combined with the automatic docking mechanism, it forms a complete automatic water supply system, improving operational efficiency.

[0068] For example, such as Figure 5 and Figure 6 As shown, in some examples, two drain pipes 5 are connected to the first water inlet pipe 3 and the second water inlet pipe 4 respectively, and each drain pipe 5 is equipped with an electromagnetic automatic drain valve 51, which is connected to the control system.

[0069] It should be noted that after the female connector 12 and the male connector 21 separate, the control system sends a signal, and both automatic drain valves 51 open simultaneously, allowing the residual water in the first water inlet pipe 3 and the second water inlet pipe 4 to be discharged through the drain pipe 5. After drainage is completed, the automatic drain valves 51 close, preventing the residual water in the pipes from freezing and damaging the pipes in low-temperature environments. This also prevents the residual water from breeding bacteria or producing scale in the pipes, ensuring the water quality for the next water intake.

[0070] For example, such as Figure 7 As shown, in some examples, the male connector 21 is provided with a second flange 211, which is connected to the first flange 121. Both the first flange 121 and the second flange 211 are provided with a sealing gasket 6.

[0071] The end of the male connector 21 is fixed with a second flange 211, which matches the first flange 121. Rubber sealing gaskets 6 are attached to the mating surfaces of the first flange 121 and the second flange 211. When the female connector 12 is connected to the male connector 21, the first flange 121 and the second flange 211 fit together. The flange connection enhances the firmness of the connection between the female connector 12 and the male connector 21. At the same time, the sealing gasket 6 prevents water leakage at the connection point, ensures the sealing during the water supply process, and improves the water replenishment efficiency.

[0072] It should be noted that, taking the ship unloader as an example, when the water level in the ship unloader's water tank is low, the control system will automatically issue an alarm. At this time, the operator only needs to press the automatic water filling button on the computer screen in the central control room, and the ship unloader will stop working in place, use the Beidou positioning system to find the nearest docking mechanism 2, and then automatically move to the corresponding docking mechanism 2. After arriving at the docking mechanism 1, the on-board adjustment component 11 pushes the docking female head 12 on the machine to dock with the docking male head 21 of the docking mechanism 2. After docking is completed, the automatic water filling valve 25 automatically opens, and water is added to the water tank through the first water filling pipe 3 and the second water filling pipe 4. After the water level in the tank reaches the set value, the automatic water filling valve 25 stops adding water. After the water tank is filled, the ship unloader automatically moves from the water filling position to the working position to continue working. The entire process is completed automatically, realizing automated and unmanned production.

[0073] Furthermore, the automatic water supply device of this application is applicable to equipment such as ship unloaders, material reclaimers, or pushers.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
