[0002] Ship unloaders are used for loading and unloading materials from ships at port terminals. Bridge-type grab unloaders are the most widely used. These unloaders have a main beam with a trolley mounted on it. The grab bucket is connected to the trolley. A winch and other drive unit are installed on the main beam, connected to the trolley and used to drive the trolley to move back and forth along the main beam. As the trolley moves, it moves the grab bucket, thereby transporting the material inside.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The following is combined with Figures 1 to 7 This describes an embodiment of the present application.

[0045] According to embodiments of this application, in one aspect, a lubrication system for a ship unloader trolley is provided, such as... Figure 1 and Figure 2 As shown, it includes a trolley 1, a power supply interface, a lubrication pump station 4, and multiple lubrication pipelines 3.

[0046] Trolley 1 is mounted on the main beam 2 of the ship unloader, allowing it to travel on and reciprocate along the extension direction of the main beam 2. The first end of the main beam 2 is located on the land side, and the second end extends towards the sea side. Thus, as trolley 1 reciprocates along the extension direction of the main beam 2, it moves between the sea side and the land side, thereby enabling the use of the hook on trolley 1 to lift cargo between the sea side and the land side.

[0047] Multiple lubrication lines 3 are installed on the trolley 1, and each lubrication line 3 is connected to a corresponding lubrication point on the trolley 1. That is, each lubrication line 3 is connected to a lubrication point on the trolley 1. When lubricating oil is introduced into each lubrication line 3, each lubrication point on the trolley 1 can be lubricated.

[0048] The power supply interface is located on the main beam 2 and is used for plugging in power.

[0049] The lubrication pump station 4 is mounted on the trolley 1 or the main beam 2. The lubrication pump station 4 can be a commonly used lubricating oil supply device, which has an oil outlet pipe 41 and a power connector. The oil outlet pipe 41 is used to discharge lubricating oil, and the power connector is used to connect to power. The power connector can be plugged into a power supply connector to provide power to the lubrication pump station 4. The oil outlet pipe 41 can be connected to the lubrication pipe 3, so that after the lubrication pump station 4 is started, lubricating oil can be discharged from the oil outlet pipe 41 to the lubrication pipe 3, thereby providing lubricating oil to each part of the trolley 1 that needs lubrication.

[0050] When the lubrication pump station 4 is installed on the trolley 1, the oil outlet pipe 41 of the lubrication pump station 4 can be kept connected to the lubrication pipe 3. When it is necessary to lubricate the various parts on the trolley 1, simply move the trolley 1 to the power supply interface, plug the power connector of the lubrication pump station 4 into the power supply connector to connect it to the power supply, and then start the lubrication pump station 4 to discharge lubricating oil from the oil outlet pipe 41 to the lubrication pipe 3, thus lubricating the various parts on the trolley 1. This method is more time-saving and labor-saving than manually applying oil to each part.

[0051] After lubrication is complete, stop lubrication pump station 4 and disconnect the power supply connector from the power supply connector of lubrication pump station 4.

[0052] The oil outlet pipe 41 of the lubrication pump station 4 can be disconnected from the lubrication pipe 3 under normal conditions. When it is necessary to lubricate the various parts of the trolley 1 that need to be lubricated, the oil outlet pipe 41 of the lubrication pump station 4 can be connected to the lubrication pipe 3 first.

[0053] When the lubrication pump station 4 is installed on the main beam 2, the power supply connector can be kept connected to the power take-off connector of the lubrication pump station 4. When it is necessary to lubricate the various parts on the trolley 1, simply move the trolley 1 to the lubrication pump station 4 and connect the lubrication pipeline 3 to the oil outlet pipeline 41 of the lubrication pump station 4. Then, start the lubrication pump station 4 to discharge lubricating oil from the oil outlet pipeline 41 to the lubrication pipeline 3, thus lubricating the various parts on the trolley 1 that need lubrication. This method is more time-saving and labor-saving than manually applying oil to each part.

[0054] After lubrication is complete, stop the lubrication pump station 4 and disconnect the lubrication pipeline 3 from the oil outlet pipeline 41 of the lubrication pump station 4.

[0055] It is worth noting that the connection between the oil outlet line 41 and the lubrication line 3 can be achieved by having one oil outlet line 41 connected to each lubrication line 3, or by having multiple oil outlet lines 41 connected to each lubrication line 3 in a one-to-one correspondence.

[0056] In the case where the lubrication pump station 4 is installed on the trolley 1, the power supply connector can be located at the end of the main beam 2 closest to the land side. In this way, when the trolley 1 is moved to its initial position and located at the end of the main beam 2 closest to the land side, the power supply connector of the lubrication pump station 4 can be plugged into the power supply connector to connect it to the power supply.

[0057] When the lubrication pump station 4 is installed on the main beam 2, the power supply connector can be located at the end of the main beam 2 closer to the land side, and the lubrication pump station 4 can be located near the power supply connector, also at the end of the main beam 2 closer to the land side. In this way, when the trolley 1 is moved to its initial position at the end of the main beam 2 closer to the land side, the lubrication pipeline 3 can be connected to the oil outlet pipeline 41 of the lubrication pump station 4.

[0058] As an optional embodiment, such as Figure 3 and Figure 4 As shown, the lubrication system of the ship unloader trolley also includes an oil distributor 5. The oil distributor 5 is a commonly used oil diversion element, which has an oil inlet 51 and multiple oil outlets 52, and has multiple channels inside. Each oil outlet 52 is connected to the oil inlet 51 through a channel.

[0059] Each oil outlet 52 is connected to a corresponding lubrication pipe 3, meaning that each oil outlet 52 on the distributor 5 is connected to a lubrication pipe 3 to a lubrication point on the trolley 1. The oil outlet pipe 41 of the lubrication pump station 4 can be connected to the oil inlet 51 of the distributor 5. After the oil outlet pipe 41 discharges lubricating oil to the oil inlet 51 of the distributor 5, the lubricating oil flows to each oil outlet 52 of the distributor 5, and then flows to a lubrication point on the trolley 1 through a corresponding lubrication pipe 3.

[0060] When the lubrication pump station 4 is installed on the trolley 1, after connecting the oil outlet pipe 41 of the lubrication pump station 4 to the oil inlet 51 of the oil distributor 5, the oil outlet pipe 41 of the lubrication pump station 4 can be connected to multiple lubrication pipes 3 respectively, making the installation more convenient.

[0061] When the lubrication pump station 4 is installed on the main beam 2, the power supply connector can be kept energized with the power take-off connector of the lubrication pump station 4. When lubrication is required at various points on the trolley 1, simply move the trolley 1 to the lubrication pump station 4, connect the oil outlet pipe 41 of the lubrication pump station 4 to the oil inlet 51 of the oil distributor 5, and then start the lubrication pump station 4 to discharge lubricating oil from the oil outlet pipe 41 to the oil inlet 51 of the oil distributor 5. The oil will then flow to each oil outlet 52 and through the corresponding lubrication pipe 3 to each point on the trolley 1, thus lubricating the points on the trolley 1. The connection is more convenient.

[0062] Similarly, after lubrication is complete, simply disconnect the oil outlet pipe 41 of the lubrication pump station 4 from the oil inlet 51 of the oil distributor 5, making disassembly easier.

[0063] In optional embodiments, such as Figure 3 and Figure 4 As shown, at least two oil distributors 5 and two oil outlet lines 41 are provided. The oil inlet 51 of each oil distributor 5 is adapted to be connected to the oil outlet line 41 in a one-to-one correspondence.

[0064] Each oil outlet 52 of each oil distributor 5 is connected to a lubrication point on the trolley 1 via a lubrication pipe 3. When the lubrication pump station 4 is started, each oil outlet pipe 41 can discharge lubricating oil.

[0065] When lubrication is required at various points on the trolley 1, each oil outlet pipe 41 of the lubrication pump station 4 is connected to the oil inlet 51 of an oil distributor 5. After the lubrication pump station 4 is started, lubricating oil is discharged from the oil outlet pipe 41 of each lubrication pump station 4, so that lubricating oil can be introduced into the oil inlet 51 of each oil distributor 5.

[0066] For each oil distributor 5, the lubricating oil flowing from its inlet 51 to its outlet 52 is then delivered through a corresponding lubrication pipe 3 to a specific lubrication point on the trolley 1. This allows for simultaneous lubrication of multiple points.

[0067] For a small vehicle 1 with four wheels, there are four oil distributors 5 and four oil outlet pipes 41. The oil inlet 51 of each oil distributor 5 is adapted to be connected to the oil outlet pipe 41 one by one.

[0068] Each distributor 5 is set up for each lubrication point on a wheel, that is, there is a one-to-one correspondence between the distributor 5 and the wheel.

[0069] For each oil distributor 5, each of its oil outlets 52 is connected to a corresponding lubrication pipe 3 to a lubrication point on the wheel. When the lubrication pump station 4 is started, one of its oil outlet pipes 41 discharges lubricating oil into one oil distributor 5, thus allowing lubricating oil to enter the oil inlet 51 of that distributor 5. The lubricating oil flowing from its inlet 51 to each oil outlet 52 flows through a lubrication pipe 3 to a corresponding lubrication point on the wheel. This achieves lubrication of each lubrication point on a wheel.

[0070] Since the four oil outlet pipes 41 of the lubrication pump station 4 correspond one-to-one with the four oil distributors 5, after the lubrication pump station 4 is started, lubricating oil can be introduced into the oil inlet 51 of each oil distributor 5, so that the lubrication of each part of the four wheels can be lubricated at the same time.

[0071] In a further embodiment, such as Figure 3 As shown, the lubrication system of the ship unloader trolley also includes at least two connecting pipes 6. Each connecting pipe 6 has a first end and a second end. The first end of each connecting pipe 6 is connected to the oil inlet 51 of each oil distributor 5 in a one-to-one correspondence. The second end of each connecting pipe 6 is located on the same side of the trolley 1, and is located on the side of the trolley 1 closest to the power supply interface in the width direction of the main beam 2.

[0072] In this way, the second end of each connecting pipe 6 is adapted to be connected to each oil outlet pipe 41 in a one-to-one correspondence. After connecting each oil outlet pipe 41 of the lubrication pump station 4 to the second end of each connecting pipe 6 in a one-to-one correspondence, each oil outlet pipe 41 of the lubrication pump station 4 can be connected to the oil inlet 51 of each oil distributor 5 in a one-to-one correspondence.

[0073] Since the second ends of each connecting pipe 6 are located on the same side of the trolley 1, it is more convenient to connect the second ends of each connecting pipe 6 to each oil outlet pipe 41 in a one-to-one correspondence.

[0074] As an optional embodiment, such as Figure 3 As shown, the lubrication system of the ship unloader trolley also includes a quick-connect male connector 7 and a quick-connect female connector 8. The quick-connect male connector 7 and quick-connect female connector 8 are mated together, allowing them to be plugged into each other to form a quick connector. One of the quick-connect male connector 7 and quick-connect female connector 8 is located on the oil outlet pipe 41, and the other is connected to the lubrication pipe 3, so that when the quick-connect male connector 7 and quick-connect female connector 8 are connected, the oil outlet pipe 41 is connected to the lubrication pipe 3.

[0075] The quick-connect male connector 7 is installed on the oil outlet line 41, and the quick-connect female connector 8 is connected to the lubrication line 3; or the quick-connect female connector 8 is installed on the oil outlet line 41, and the quick-connect male connector 7 is connected to the lubrication line 3.

[0076] Thus, when the lubrication pump station 4 is installed on the trolley 1, when connecting the oil outlet pipe 41 of the lubrication pump station 4 to the lubrication pipe 3, quick-connect male connector 7 and quick-connect female connector 8 can be used to connect each oil outlet pipe 41 of the lubrication pump station 4 to the lubrication pipe 3, making the installation more convenient.

[0077] When the lubrication pump station 4 is installed on the main beam 2, the power supply connector can be kept connected to the power take-off connector of the lubrication pump station 4. When it is necessary to lubricate the various parts on the trolley 1, simply move the trolley 1 to the lubrication pump station 4, and connect the quick-connect male connector 7 and quick-connect female connector 8 to connect the lubrication pipeline 3 to the oil outlet pipeline 41 of the lubrication pump station 4, making the connection more convenient. Then, start the lubrication pump station 4 to discharge lubricating oil from the oil outlet pipeline 41 to the lubrication pipeline 3, so that lubricating oil can be introduced into each part on the trolley 1 for lubrication.

[0078] Specifically, the quick-connect male connector 7 can be installed on the oil outlet pipe 41, and the quick-connect female connector 8 can be installed at the second end of the connecting pipe 6. After connecting the quick-connect male connector 7 and the quick-connect female connector 8, the oil outlet pipe 41 can be connected to the second end of the connecting pipe 6, thereby connecting the oil outlet pipe 41 to the oil inlet 51 of the oil distributor 5, and then connecting the oil outlet pipe 41 to the lubricating oil circuit.

[0079] Alternatively, the quick-connect female connector 8 can be installed on the oil outlet line 41, and the quick-connect male connector 7 can be installed at the second end of the connecting pipe 6.

[0080] In optional embodiments, such as Figure 5 and Figure 7 As shown, the lubrication system of the ship unloader trolley also includes a drive unit 9, sensors, and a controller.

[0081] The drive unit 9 is connected to the trolley 1, enabling it to drive the trolley 1 to move along the extension direction of the main beam 2 between the first and second ends of the main beam 2. When the drive unit 9 stops driving the trolley 1, it acts on the trolley 1 to suspend it.

[0082] The sensor is installed on one of the quick-connect male connector 7 and quick-connect female connector 8, so that when the quick-connect male connector 7 and quick-connect female connector 8 are plugged into each other, the sensor can detect the information and send a signal.

[0083] The controller is communicatively connected to both the sensor and the drive unit 9, enabling the controller to receive signals from the sensor and control the drive unit 9 to drive the trolley 1.

[0084] Thus, when the lubrication pump station 4 is located on the main beam 2, the power supply connector can maintain a power connection with the power take-off connector of the lubrication pump station 4. When lubrication is required at various points on the trolley 1, simply move the trolley 1 to the lubrication pump station 4, connect the quick-connect male connector 7 and the quick-connect female connector 8 to connect the lubrication pipeline 3 to the oil outlet pipeline 41 of the lubrication pump station 4. At this time, the sensor sends a signal to the controller, and the controller then sends a control signal to the drive device 9 to control the drive device 9 to hover the trolley 1. Then, the lubrication pump station 4 is started to discharge lubricating oil from the oil outlet pipeline 41 to the lubrication pipeline 3, thereby lubricating each point on the trolley 1. Because the trolley 1 is hovered during the lubrication process, it avoids damage or disconnection of the pipeline caused by the movement of the trolley 1.

[0085] When the quick-connect male connector 7 and quick-connect female connector 8 are separated, the sensor can also detect this information and send a signal. Thus, after lubrication is completed, when the quick-connect male connector 7 and quick-connect female connector 8 are disconnected, the sensor sends a signal to the controller, and the controller no longer controls the drive unit 9 to hover the trolley 1.

[0086] It is worth noting that, when the lubrication pump station 4 is installed on the trolley 1, the oil outlet pipe 41 of the lubrication pump station 4 should be disconnected from the lubrication pipe 3 under normal conditions, that is, the quick-connect male connector 7 and quick-connect female connector 8 should be separated under normal conditions to avoid affecting the normal movement of the trolley 1. When it is necessary to lubricate the various parts on the trolley 1 that need lubrication, simply plug in the quick-connect male connector 7 and quick-connect female connector 8.

[0087] The drive unit 9 can be a separate unit or a power mechanism on the ship unloader used to drive the trolley 1. Specifically, the drive unit 9 can be a winch.

[0088] The sensor can be a pressure sensor or an infrared sensor.

[0089] The controller can be set up independently or it can be part of the electrical control system on the ship unloader used to control the power mechanism.

[0090] In optional embodiments, such as Figure 3 As shown, the oil outlet pipe 41 is a flexible pipe, meaning it can be bent arbitrarily. Therefore, when the lubrication pump station 4 is located on the main beam 2, to lubricate the various points on the trolley 1 that need lubrication, the trolley 1 only needs to be moved to the lubrication pump station 4, without needing to be precisely positioned. Because the oil outlet pipe 41 can be bent arbitrarily, the quick-connect male connector 7 and quick-connect female connector 8 can be aligned by bending the oil outlet pipe 41, making connection more convenient.

[0091] In the case where the lubrication pump station 4 is installed on the trolley 1, it is not necessary to install the lubrication pump station 4 in the designated position. The quick-connect male connector 7 and quick-connect female connector 8 can be aligned by bending the oil outlet pipe 41 to avoid the installation position of the lubrication pump station 4 being offset, which would prevent the quick-connect male connector 7 and quick-connect female connector 8 from being unable to connect.

[0092] As an optional embodiment, the lubrication pump station 4 includes a lubrication pump, an oil tank, a control module, and a power connector. The lubrication pump is a commonly used oil pump, which has an oil suction port and an oil discharge port. When the lubrication pump starts, it pumps oil from the oil suction port to the oil discharge port.

[0093] The oil tank is used to store and store oil. The oil suction port of the lubrication pump is connected to the oil tank, and the oil discharge port of the lubrication pump is connected to the oil outlet pipe 41. Thus, the lubrication pump can pump the oil in the oil tank to the oil outlet pipe 41.

[0094] like Figure 6 As shown, the control module is communicatively connected to the lubrication pump, enabling it to control the pump's start and stop. The control module can be a programmable logic controller (PLC).

[0095] The power connector is connected to the control module and the lubrication pump, thereby enabling it to draw power and supply power to the control module and the lubrication pump.

[0096] When lubrication is required at various points on the trolley 1, the trolley 1 is moved to the power supply interface, connecting the oil outlet pipe 41 of the lubrication pump station 4 to the lubrication pipe 3. The power connector of the lubrication pump station 4 is plugged into the power supply connector to provide power to the control module and lubrication pump of the lubrication pump station 4. The control module controls the lubrication pump to start, discharging lubricating oil from the oil outlet pipe 41 to the lubrication pipe 3, thus lubricating each point on the trolley 1. After lubrication is complete, the control module controls the lubrication pump to start and stop.

[0097] This setup allows for remote or conditional control of the lubrication pump via a control module.

[0098] In an optional embodiment, the unloader trolley lubrication system further includes a timing module 10 and an alarm 11. For example... Figure 6 As shown, the timing module 10 is communicatively connected to the control module, and the alarm 11 is communicatively connected to the control module.

[0099] When the lubrication pump station 4 is installed on the main beam 2, and lubrication is required for each part of the trolley 1, the trolley 1 is moved to the power supply interface, and the oil outlet pipe 41 of the lubrication pump station 4 is connected to the lubrication pipe 3. The power connector of the lubrication pump station 4 is plugged into the power supply connector to provide power to the control module and the lubrication pump of the lubrication pump station 4. The control module controls the lubrication pump to start, so that lubricating oil is discharged from the oil outlet pipe 41 to the lubrication pipe 3, and lubricating oil can be introduced into each part of the trolley 1 to lubricate. At the same time, the control module controls the timing module 10 to start timing. After the first time has elapsed, the timing module 10 sends a signal to the control module, and then the control module controls the lubrication pump to stop. At this time, lubrication is completed. At the same time, the control module controls the timing module 10 to start timing. After the second time has elapsed, the control module controls the alarm 11 to sound an alarm to remind the operator that the trolley 1 needs lubrication.

[0100] This setup eliminates the need for the operator to manually stop the lubrication pump and also promptly reminds the operator that the trolley 1 needs lubrication.

[0101] The timing module 10 can be a time relay, and the alarm 11 can be an alarm light or a buzzer.

[0102] It is worth noting that when the lubrication pump station 4 is installed on the trolley 1, the power connector needs to be disconnected from the power supply interface after lubrication is completed, which will prevent the control module from receiving power. In this case, the alarm function of the alarm 11 can be disabled. Alternatively, a separate power storage device can be provided for the control module to supply power when the power connector is disconnected from the power supply interface.

[0103] According to embodiments of this application, another aspect also provides a ship unloader, such as... Figure 7 As shown, this includes any of the above-mentioned unloader trolley lubrication systems. The technical effects brought by this unloader are the same as those of the unloader trolley lubrication system, so they will not be described in detail here.

[0104] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by this application.
