[0025] Please see Figure 1-2As shown in the embodiment of this utility model, a dry oil lubrication distribution device includes an oil storage tank 1, which is used to store dry oil to ensure that the oil supply system has a sufficient oil source. The oil storage tank 1 is connected to the input end of the main oil pump 3 through the oil supply pipe 2. The main oil pump 3 serves as the power source of the system, drawing dry oil from the oil storage tank 1 and providing a certain pressure to push the dry oil to flow along the pipeline. The output end of the main oil pump 3 is connected to the distributor oil supply component 5 through the oil delivery pipe 4. The oil supply pipe 2 and the oil delivery pipe 4 constitute the main channel of the oil circuit system, which is used to connect the oil storage tank 1, the main oil pump 3 and the distributor oil supply component 5. The distributor oil supply component 5 is electrically connected to the controller 10. The controller 10 is a PLC controller 10 as the core control unit, which has built-in parameter tables such as lubrication cycle, single lubrication amount, and oil quantity setting value of each lubrication point. Operators can set or modify lubrication parameters through the human-machine interface (HMI), and control the flow distribution of each lubrication point through the controller 10 to adjust the oil supply component 5 of the distributor. This avoids insufficient oil at the lubrication points, which can lead to poor lubrication. It can control the oil distribution of each lubrication point, reducing the occurrence of excessive oil at some lubrication points causing waste, or insufficient oil at some lubrication points leading to poor lubrication.
[0026] In one embodiment, see Figure 1 and Figure 2 As shown, a pressure sensor 6 is installed on the oil supply pipe 4. The pressure sensor 6 is used to monitor the pressure status of the grease in the oil supply pipe 4 in real time. In multi-channel oil supply, if a channel of a distributor oil supply component 5 is blocked, the pressure of the oil supply pipe 4 will rise. By analyzing the output data of the pressure sensor 6, it can be determined whether the oil supply of the system is balanced, thereby assisting maintenance personnel to clean or repair faulty channels in a timely manner and avoid equipment wear or failure caused by uneven lubrication.
[0027] In one embodiment, see Figure 1 and Figure 2 As shown, the distributor oil supply assembly 5 includes a distribution oil tank 51. The distribution oil tank 51 is connected to an oil delivery pipe 4 through a main oil pipeline 52. The main oil pipeline 52 is connected to an oil supply assembly 54 through several branch oil pipes 53. The distribution oil tank 51 acts as a pressure buffer and can stably regulate the pressure of the high-pressure grease delivered from the main oil pump 3. The main oil pipeline 52 adopts a parallel oil supply method, and the pressure is evenly transmitted to multiple oil supply assemblies 54 through the branch oil pipes 53. Each oil supply assembly 54 is independent of each other, and the oil supply volume is controlled by the displacement of the plunger 542 inside it. Each branch oil pipe 53 is equipped with a distribution valve 7, which can adjust and control the start and stop of the oil supply of each line to achieve on-demand distribution and distribute the grease to each lubrication point.
[0028] In one embodiment, see Figure 1 and Figure 2As shown, the oil supply assembly 54 includes a grease injection cylinder 541, with a plunger 542 slidably connected inside the grease injection cylinder 541. A spring 543 is installed between the plunger 542 and the inner wall of the grease injection cylinder 541. The oil inlet 544 of the grease injection cylinder 541 is connected to the oil distribution pipe 53. An oil outlet 545 is provided on the side of the grease injection cylinder 541 away from the oil inlet 544. A microswitch 9 is located inside the grease injection cylinder 541 and is used to detect the displacement state of the plunger 542, thereby indirectly determining whether the grease injection or discharge process is smooth and whether the plunger 542 is in good condition. 42 Whether the operation is in place: When the plunger 542 completes the reciprocating motion under the action of the spring 543, it will trigger the micro switch 9 at the end of the stroke to detect the movement process of the plunger 542. This can be used as a signal basis to determine whether an oil injection action has been completed. Whether the micro switch 9 is triggered or not can provide feedback on whether each oil injection cylinder 541 has completed the oil supply normally, thereby realizing closed-loop control of the system and improving the reliability of oil supply. The specific model of the micro switch 9 is Omron D2F, which can effectively improve the accuracy of the entire distributor oil supply assembly 5. When the system is pressurized and the pressure in the main oil pipeline 52 increases, grease enters the distribution oil cylinder 541 through the oil inlet 544. The grease pushes the plunger 542 upward to compress the spring 543, filling the distribution oil cylinder 541 with grease. After the main system is depressurized, the spring 543 pushes the plunger 542 downward, and the grease is pushed to the lubrication point through the oil outlet 545. When the main oil pump 3 pressurizes dry oil into the distributor supply assembly 5, the main oil pump 3 provides high-pressure grease to the distribution oil cylinder 541, pushing the plunger 542 upward and compressing the spring 543. Grease fills the cavity below the plunger 542. The plunger 542 returns downward under the push of the spring 543, pushing the grease in the cavity from the oil outlet 545 to the lubrication point. Each distribution oil cylinder 541 is independent. In the circuit, each push of the plunger 542 triggers the microswitch 9, indicating one oil output cycle. The controller 10 calculates the oil supply based on this. The controller 10 detects the action of the microswitch 9 in real time. By monitoring the microswitch 9 at the oil outlet 545 in real time, it detects whether the displacement of the plunger 542 at the end of the movement is in place, and determines whether one oil injection action is completed. If the oil injection action reaches the required amount, it is considered that the oil supply at the lubrication point is complete; otherwise, oil supply continues or an alarm is triggered. By controlling the number of oil injection cycles in each distributor oil supply component 5, the oil supply of each lubrication point is adjusted and controlled, so as to achieve on-demand control of each lubrication point.
[0029] In one embodiment, see Figure 1 and Figure 2 As shown, whether the micro switch 9 is triggered or not can provide feedback on whether each oil injection cylinder 541 has completed oil supply normally, thereby realizing closed-loop control of the system and improving the reliability of oil supply. The specific model of the micro switch 9 is Omron D2F, which can effectively improve the accuracy of the entire distributor oil supply assembly 5.
[0030] In one embodiment, see Figure 1 and Figure 2 As shown, each oil distribution pipe 53 is equipped with a distribution valve 7. The distribution valve 7 is installed on the oil distribution pipe 53. The distribution valve 7 is installed on each oil distribution pipe 53 and is fixed at the oil pipe interface by quick-connect connection. The distribution valve 7 serves as the switching device for each oil supply line and is used to control whether the grease enters the corresponding oil supply component 54. This allows for zoned oil supply or individual control of the lubrication points, improving system flexibility.
[0031] In one embodiment, see Figure 1 and Figure 2 As shown, a flow sensor 8 is installed at the oil outlet 545 of several oil injection cylinders 541. The flow sensor 8 at the oil outlet 545 of each oil injection cylinder 541 can detect and provide feedback on the actual oil supply of the lubrication branch in real time, ensuring that the oil supply at each lubrication point reaches the preset target value.
[0032] In one embodiment, see Figure 1 and Figure 2 As shown, the oil pipeline 4 is connected to the main oil pipeline 52 through the first quick connector 11. The first quick connector 11 is connected to the connector seat of the main oil pipeline 52 by means of threads, so as to realize the quick and reliable connection between the oil pipeline 4 and the main oil pipeline 52, which facilitates disassembly, installation and maintenance.
[0033] In one embodiment, see Figure 1 and Figure 2 As shown, the main oil pipeline 52 is connected to the branch oil pipeline 53 through the second quick connector 12. The main oil pipeline 52 is connected to the branch oil pipeline 53 through several second quick connectors 12. The branch oil pipeline 53 is connected to the connector seat of the main oil pipeline 52 through the second quick connectors 12 by means of threads, so as to realize the quick and reliable connection between the main oil pipeline 52 and the branch oil pipeline 53, which facilitates inspection and maintenance.
[0034] In one embodiment, see Figure 1 and Figure 2 As shown, the main oil pipeline 52 is connected to the branch oil pipeline 53 via the second quick connector 12.
[0035] In one embodiment, see Figure 1 and Figure 2As shown, pressure sensor 6 monitors the pressure data in the main oil pipeline 52 in real time and provides feedback on the current oil supply status of the system; flow sensor 8 monitors the grease flow rate at each oil outlet to ensure accurate oil supply at each lubrication point; micro switch 9 is installed in the distribution oil cylinder 541 to detect whether the plunger 542 has reached the set stroke position, thereby determining whether the distribution oil injection is complete; the opening and closing status of the distribution valve 7 is uniformly controlled by the controller 10 to achieve independent control of each distribution oil pipe 53; the controller 10 analyzes the data collected by the above components in real time: if the flow rate at a certain lubrication point is too high or too low, the controller 10 automatically adjusts the distribution valve 7 according to the feedback; if the pressure is abnormal (too high / too low), the controller 10 can alarm or adjust the working status of the main oil pump; micro switch 9 provides feedback on the status of plunger 542 to determine whether the distribution oil injection action is normal or stuck; the controller 10 can be a PLC control module with analog / switching input ports.
[0036] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
