Description

Technical Field

[0001] This utility model relates to the field of lubrication technology, and in particular to an automatic lubrication system and a stacker. Background Technology

[0002] Stacker cranes are heavy-duty equipment widely used in mines, ports, power plants, and other locations, primarily for the storage and transport of materials. Due to their harsh working environment, heavy loads, and long operating times, key components of stacker cranes (such as slewing bearings, wheels, and transmission gears) require regular lubrication to reduce wear, extend service life, and ensure reliable equipment operation.

[0003] In existing technologies, the lubrication system of stacker cranes uses a single pipeline or a simple distributor, without considering the differences in flow resistance of grease in long-distance, multi-branch pipelines. Different lubrication points, due to varying distances from the pump station, experience uneven pressure loss, resulting in insufficient grease supply to distant lubrication points. This easily leads to some lubrication points experiencing accelerated wear due to insufficient lubrication, while others suffer from waste or contamination due to excessive lubrication.

[0004] Therefore, this application aims to address the issue that the different oil pressures required at different lubrication points of a stacker can easily lead to insufficient or excessive oil levels at these points. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic lubrication system and a stacker, which aims to adjust the oil pressure of the stacker at different lubrication points in a timely manner, ensure that the oil quantity at the lubrication points of the stacker meets the requirements, and at the same time avoid oil waste.

[0006] To achieve the above objectives, this utility model proposes an automatic lubrication system, comprising:

[0007] Lubrication pump station, used to pump out oil;

[0008] At least one oil replenishing component, connected to the lubrication pump station, is used to receive oil from the lubrication pump station and distribute the received oil. The oil replenishing component includes at least one oil replenishing unit, which includes:

[0009] A supply valve is connected to the lubrication pump station;

[0010] The oil outlet component is connected to the oil outlet end of the supply valve, and a pressure element is installed in the path of the oil flowing out to acquire and generate an electrical signal of the oil pressure.

[0011] The control unit receives the electrical signal and generates a correction command based on the electrical signal to control the opening degree of the supply valve.

[0012] Furthermore, it includes a control box electrically connected to the control unit, the control box being electrically connected to a drive line and a feedback line corresponding to the oil replenishment unit, the drive line and the feedback line being electrically connected to the input end and the output end of the replenishment valve and the oil outlet component, respectively.

[0013] Furthermore, the input end of the supply valve is an electric actuator, and the drive circuit is electrically connected to the electric actuator to adjust the opening degree of the supply valve.

[0014] Furthermore, the lubrication pump station includes a lubrication pump and a grease outlet valve connected together, and an oil supply pipe is connected between the oil outlet end of the grease outlet valve and the supply valve.

[0015] Furthermore, the lubrication pump station includes a grease replenishment pump and a grease replenishment valve. The grease replenishment valve is located between the lubrication pump and the grease outlet valve. The oil outlet end of the grease replenishment pump is connected to the oil inlet end of the grease outlet valve. Both the grease replenishment pump and the lubrication pump can flow oil to the grease outlet valve through the grease replenishment pump.

[0016] Furthermore, the lubrication pump station includes a control cabinet electrically connected to the control unit, and the control cabinet is electrically connected to the grease replenishment pump, the lubrication pump, and the grease replenishment valve.

[0017] This application also discloses a stacker equipped with the aforementioned automatic lubrication system, the stacker including a plurality of lubrication points, each of the lubrication points being connected to the oil outlet component.

[0018] Furthermore, the stacker's lubrication points are divided into multiple different lubrication zones, each lubrication zone is correspondingly set with an oil replenishment component, and the number of lubrication points in each lubrication zone corresponds to the number of oil replenishment units.

[0019] The above technical solution has the following advantages:

[0020] This invention employs an interactive method between an oil replenishment unit and a control unit. The oil outlet component of the oil replenishment unit acquires the pressure value of the oil flowing out in real time and converts the pressure value into an electrical signal transmitted to the control unit. The control unit can then output correction commands based on the electrical signal to adjust the opening of the replenishment valve in the oil replenishment unit, thereby dynamically adjusting the oil pressure required for different lubrication points. This ensures smooth oil flow, guarantees sufficient oil quantity at the stacker lubrication points, and avoids oil waste. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0029] like Figure 1 and Figure 2 As shown, an automatic lubrication system includes a lubrication pump station 1, at least one oil replenishing component 5, and a control unit 2. The lubrication pump station 1 is used to pump out oil. The oil replenishing component 5 is connected to the lubrication pump station 1 and is used to receive oil from the lubrication pump station 1 and distribute the received oil. The oil replenishing component 5 includes at least one oil replenishing unit, which includes a replenishing valve 51 and an oil outlet component 52. The replenishing valve 51 is connected to the lubrication pump station 1. The oil outlet component 52 is connected to the oil outlet end of the replenishing valve 51, and a pressure element is provided in the path of the oil flowing out to acquire and generate an electrical signal of the oil pressure. The control unit 2 receives the electrical signal and generates a correction command according to the electrical signal to control the opening degree of the replenishing valve 51. The lubrication pump station 1 is used to provide oil and pump it to the oil replenishment unit 5. The oil replenishment unit 5 distributes the received oil to the positions that need lubrication, thereby providing a lubrication effect. During the oil discharge process of the oil replenishment unit 5, the control unit 2 continuously acquires the pressure signal of the oil flowing out of the oil replenishment unit 5 and adjusts the oil pressure in time to avoid blockage and make it difficult for the oil to flow out smoothly. The pressure element measures the pressure of the oil in the oil outlet component 52 in real time and transmits the acquired pressure electrical signal to the control unit 2.

[0030] Specifically, the control unit 2 preferably uses a PLC to process electrical signals. The lubrication pump station 1 pumps oil to the inlet of the supply valve 51 in each oil supply component 5. After receiving the oil, the supply valve 51 discharges the oil from the outlet component 52. During the oil discharge process, the supply valve 51 can be adjusted at any time to adjust the oil output by changing the opening degree. The oil output can be controlled according to each lubrication position. The supply valve 51 can be adjusted by a combination of manual handwheel and gauge. If the oil pressure at the outlet component 52 is lower or higher than the required oil output pressure, the gauge needle will deflect. At this time, the handwheel can be turned to adjust the pressure. Since the subsequent lubrication position will not change after the adjustment, the handwheel does not need to be adjusted many times later. This application can adjust the supply valve 51 by electric or pneumatic means. If the pressure at the outlet component 52 is lower or higher than the required oil output pressure, the adjustment and calibration effect can be automatically achieved.

[0031] like Figure 1 and Figure 2 As shown, this application includes a control box 3 electrically connected to the control unit 2. The control box 3 is electrically connected to a drive line 31 and a feedback line 32 corresponding to the oil replenishment unit. The drive line 31 and the feedback line 32 are respectively electrically connected to the input and output ends of the supply valve 51 and the oil outlet component 52. The control box 3 interacts with the control unit 2. The feedback line 32 transmits signals to the control box 3, which then transmits the signals to the control unit 2 for processing. When the oil pressure at the oil outlet component 52 is lower or higher than the required oil outlet pressure, the control unit 2 sends a correction signal to the control box 3. The control box 3 adjusts the opening of the supply valve 51 via the drive line 31, thereby achieving dynamic pressure adjustment at different lubrication points.

[0032] like Figure 3 As shown, the input end of the supply valve 51 is an electric actuator, and the drive line 31 is electrically connected to the electric actuator to adjust the opening of the supply valve 51. The electric actuator can be driven by an electric motor, such as a motor, or by a pneumatic motor, such as a combination of an electric cylinder and a piston.

[0033] like Figure 1 and Figure 2 As shown, the lubrication pump station 1 includes a lubrication pump 12 and a grease outlet valve 15 connected together. The oil outlet end of the grease outlet valve 15 is connected to the supply valve 51 by an oil supply pipe 4. The oil supply pipe 4 is used to supply oil from the lubrication pump station 1 to the supply valve 51. The oil supply pipe 4 can be used in various ways, such as several parallel oil supply pipes 4, each corresponding to the number of supply valves 51. Alternatively, depending on the lubrication location, a combination of main pipelines and branch pipelines can be used to supply oil. This application preferably adopts the second method to reduce the number of oil supply pipes 4 and the complex maintenance costs.

[0034] like Figure 2As shown, the lubrication pump station 1 includes a grease replenishment pump 11 and a grease replenishment valve 14. The grease replenishment valve 14 is located between the lubrication pump 12 and the grease outlet valve 15. The oil outlet end of the grease replenishment pump 11 is connected to the oil inlet end of the grease outlet valve 15. Both the grease replenishment pump 11 and the lubrication pump 12 can supply oil to the grease outlet valve 15 through the grease replenishment pump 11. The grease replenishment pump 11 is used to provide secondary oil supply to the lubrication pump 12, pressurizing the subsequent oil supply and further improving the oil flow in the oil supply pipe 4.

[0035] like Figure 2 As shown, to improve the monitoring of the lubrication pump station 1, the lubrication pump station 1 includes a control cabinet 13 electrically connected to the control unit 2. The control cabinet 13 is electrically connected to the grease pump 11, the lubrication pump 12, and the grease valve 14. The control cabinet 13 acquires the pressure values ​​of the grease pump 11, the lubrication pump 12, and the grease valve 14 in real time, converts these pressure values ​​into electrical signals, and transmits them to the control unit 2. The control unit 2 observes the operating status of the lubrication pump station 1 through a display panel, which helps with subsequent maintenance and troubleshooting.

[0036] like Figure 3 As shown, the oil outlet component 52 can be an oil outlet pipe, an oil outlet nozzle, or an oil outlet connector, which facilitates connection to the location requiring lubrication. The specific design is determined based on different usage scenarios.

[0037] like Figures 2 to 5 As shown, a stacker is equipped with the aforementioned automatic lubrication system. The stacker includes several lubrication points, each of which is connected to an oil outlet component 52. The oil outlet component 52 can be directly connected to the corresponding lubrication point to perform oil supply operation for each lubrication point. At the same time, the control unit 2 detects the pressure value of each oil outlet component 52 in real time to ensure that the pressure of the oil outlet component 52 meets the oil supply requirements.

[0038] Specifically, the stacker's lubrication points are divided into multiple different lubrication zones, each corresponding to an oil replenishment component 5. The number of lubrication points in each lubrication zone corresponds to the number of oil replenishment units. All rotating points of the stacker require lubrication, which are the aforementioned lubrication points. This method concentrates the lubrication points in each lubrication zone, allowing for the selection of the corresponding oil replenishment component 5 based on quantity requirements. This significantly simplifies the oil supply pipe 4, drive circuit 31, and feedback circuit 32, facilitating subsequent inspection and maintenance.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
