Its main function is to ensure the lubrication state of relevant components during elevator operation, reduce wear and friction, and improve the safety and stability of the elevator. An elevator lubricating oil adding device usually consists of a lubricating oil storage container, an oil supply pipeline, a control device, and sensors, etc. Through preset parameters and sensor detection, the device can automatically or regularly add an appropriate amount of lubricating oil to relevant parts of the elevator according to needs to maintain a good lubrication effect. This device can be designed and adjusted according to different elevator systems and requirements to ensure an appropriate lubrication state is always maintained during elevator operation, thereby extending the service life of elevator components and improving the working efficiency and reliability of the elevator.

[0003] The utility model patent with the publication number CN219217184U discloses an elevator lubricating oil adding device, which relates to the technical field of elevator lubricating oil adding devices. The adding device aims to solve the technical problems of being unable to safely add lubricating oil and having low adding and painting efficiency in the prior art. The adding device includes a mounting base, a magnet base is fixedly connected to the lower end of the mounting base, a chassis is fixedly connected to the upper end of the mounting base, a clamping assembly is installed at the rear end inside the chassis, and an adjusting assembly is installed at the upper end of the mounting base. The adding device uses a spray head in cooperation with the adjusting assembly. The second motor can drive the scraper and the brush to contact the guide rail to remove rust and dirt on the guide rail, and evenly add and apply lubricating oil to the outer surface of the elevator guide rail. The adding device is installed on the top of the elevator through the mounting base in cooperation with the clamping assembly, or adsorbed on the top of the elevator using the magnet base, which solves the problem that maintenance personnel need to stand on the top of the elevator during traditional maintenance, greatly reducing potential safety hazards.

[0062] An oil inlet passage 33 is opened on the left and right sides of the outer surface of the ball 31. When the ball 31 rotates to make the oil inlet passage 33 coincide with the oil groove 32, the lubricating oil flows from the oil inlet passage 33 into the oil groove 32;

[0063] The frame 34 is provided at the top of the oil storage barrel 1;

[0066] The control unit 37 is electrically connected to the digital flowmeter 36 and the motor 35, and can control the operation of the motor 35 according to the preset addition amount to achieve quantitative lubrication of the elevator guide rail.

[0067] In this technical solution, the lubricating oil is stored in the oil storage barrel 1. The oil storage barrel 1 is provided with an oil delivery nozzle 2. The oil delivery nozzle 2 is located at the end of the oil storage barrel 1 and is used to evenly add the lubricating oil to the elevator guide rail. The transmission shaft 30 in the metering mechanism 3 rotates inside the oil storage barrel 1. One end of the transmission shaft 30 extends out of the oil storage barrel 1 and is connected to the motor 35. The motor 35 drives the transmission shaft 30 to rotate. The ball 31 is arranged at the end of the transmission shaft 30 and is located inside the oil delivery nozzle 2. The rotation of the ball 31 drives the lubricating oil to flow in the oil delivery nozzle 2, and through the oil inlet channel 33 coinciding with the oil groove 32, the lubricating oil flows from the oil inlet channel 33 into the oil groove 32 and is evenly added to the elevator guide rail from the oil groove 32 in the oil delivery nozzle 2 to ensure uniform lubrication of the guide rail surface. The digital flowmeter 36 is arranged at the output end of the oil delivery nozzle 2 to measure the flow of the lubricating oil in real time and display the data. The digital flowmeter 36 records the actual flow of the lubricating oil for monitoring and adjustment. The control unit 37 is electrically connected to the digital flowmeter 36 and the motor 35, can receive the flow data and adjust the operation of the motor 35 according to the preset addition amount. The control unit 37 ensures that the addition amount of the lubricating oil meets the set value and precisely controls the motor 35 to ensure accurate and uniform lubrication of the elevator guide rail, reduce wear and extend the service life of the equipment. Through the automated system, quantitative addition of the lubricating oil is realized, manual intervention is reduced, and the efficiency and accuracy are improved; the addition amount and flow of the lubricating oil are monitored in real time to ensure that the lubrication process meets the set standards; the oil delivery nozzle 2 evenly adds the lubricating oil to the elevator guide rail to ensure the lubrication effect; the metering mechanism 3 precisely controls the addition amount of the lubricating oil by mechanical means; the digital flowmeter 36 measures and records the lubricating oil volume flowing through the oil delivery nozzle 2 to provide real-time data; the control unit 37 adjusts the operation of the motor 35 according to the preset addition amount to achieve precise addition of the lubricating oil. This elevator lubricating oil adding device realizes automated quantitative addition of the lubricating oil through the oil storage barrel 1, the oil delivery nozzle 2 and the metering mechanism 3. The transmission shaft 30 and the ball 31 system ensure uniform distribution of the lubricating oil. The digital flowmeter 36 provides real-time flow monitoring. The control unit 37 precisely adjusts the addition amount of the lubricating oil according to the preset value. The overall system aims to improve the lubrication efficiency of the elevator, reduce manual operation, and improve the service life and operation safety of the equipment.

[0068] As Figure 1 and Figure 5 shown, in this embodiment, optimally, the control unit 37 includes:

[0069] An input module 371 for receiving the set value of the lubricating oil addition amount input by the user;

[0070] A processing module 372 for calculating and controlling the working state of the motor 35 according to the set value and the data of the digital flowmeter 36.

[0071] In this technical solution, the user inputs the set value of the required lubricating oil addition amount through the input module 371 (usually a touch screen, a keypad panel or other user interface devices). These set values usually include parameters such as the volume, flow rate or addition time of the lubricating oil. The input module 371 transmits the set value input by the user to the processing module 372. After receiving these data, the processing module 372 uses them as control signals to manage the lubricating oil addition process. The digital flowmeter 36 measures the flow rate of the lubricating oil passing through the oil delivery nozzle 2 in real time and transmits the measurement result to the processing module 372. The digital flowmeter 36 continuously monitors the flow rate to ensure that it meets the predetermined standard. The processing module 372 receives the data from the digital flowmeter 36 and compares it with the set value input by the user. Based on these data, the processing module 372 calculates whether the current flow rate meets the set value and adjusts the working state of the motor 35 to achieve the required lubricating oil addition amount. The processing module 372 adjusts the speed or switch state of the motor 35 according to the real-time data to increase or decrease the flow rate of the lubricating oil. The processing module 372 generates a control signal to instruct the motor 35 to operate according to the set working state. If the lubricating oil flow rate is insufficient, the processing module 372 will increase the working time or speed of the motor 35; if the flow rate is excessive, it will reduce the working time or speed of the motor 35 until the actual flow rate meets the set value. The control unit 37 continuously loops through the above steps to adjust the addition amount of the lubricating oil in real time, ensuring that each addition can accurately meet the set requirements. Any deviation will be detected and automatically adjusted by the processing module 372 to ensure that the addition amount of the lubricating oil strictly follows the value set by the user, achieving the expected lubrication effect, dynamically adjusting the lubricating oil addition process according to the actual flow rate data to maintain the accuracy of the addition amount. The processing module 372 uses the data from the digital flowmeter 36 to calculate and adjust the working state of the motor 35 in real time to ensure the precise addition of the lubricating oil.

[0072] Embodiment 2:

[0073] This embodiment provides an elevator lubricating oil addition device. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0074] As Figure 2 and Figure 6As shown, in this embodiment, optimally, a stirring mechanism 4 for stirring lubricating oil is provided on the transmission shaft 30. The stirring mechanism 4 includes:

[0075] A bushing 41, arranged on the transmission shaft 30;

[0076] A connecting frame 42, arranged on the outside of the bushing 41;

[0077] Stirring paddles 43, arranged on the connecting frame 42, and the stirring paddles 43 are in contact with the inner wall of the oil storage barrel 1.

[0078] In this technical solution, when the system starts to work, the motor 35 drives the transmission shaft 30 to rotate. There is a bushing 41 on the transmission shaft 30. The bushing 41 rotates with the transmission shaft 30. The bushing 41 drives the connecting frame 42 to rotate, and the connecting frame 42 drives the stirring paddles 43 to rotate. The stirring paddles 43 are in contact with the inner wall of the oil storage barrel 1 and stir the lubricating oil during the rotation process. The rotation of the stirring paddles 43 stirs the lubricating oil in the oil storage barrel 1, making each part of the lubricating oil mix evenly. The stirring force and speed can ensure the uniformity of the lubricating oil in the barrel, avoid precipitation and stratification. The uniformly stirred lubricating oil has a more stable viscosity and more consistent fluidity, which helps the oil delivery nozzle 2 to spray the lubricating oil evenly onto the elevator guide rail, ensures the uniform mixing of the lubricating oil in the oil storage barrel 1, prevents precipitation or stratification, and improves the stability and fluidity of the lubricating oil.

[0079] Embodiment 3:

[0080] This embodiment provides an elevator lubricating oil adding device. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0081] As Figure 5 shown, in this embodiment, optimally, it further includes a monitoring system 5, which is used to monitor the lubricating oil adding process in real time, record the time and amount of lubricating oil added, and provide an alarm function to issue a warning in case of an abnormality.

[0082] In this technical solution, the monitoring system 5 collects relevant data on lubricating oil addition in real time through devices such as sensors and digital flow meters 36, including information such as flow rate, addition time, and total amount. The monitoring system 5 records the collected data in a database or log system to ensure that the detailed information of each lubricating oil addition is archived. The system may process and analyze the data to generate reports or trend charts. The system displays the data during the lubricating oil addition process in real time, including the current addition amount and the remaining amount. Through the interface or dashboard, the operator can view the system status at any time to ensure that the addition of lubricating oil meets the predetermined requirements. The monitoring system 5 sets abnormal thresholds and conditions, such as the allowable flow rate range, addition time limit, etc. When the monitored data exceeds the preset range, the system will automatically identify it as an abnormal situation. Once the system detects an abnormal situation, the alarm function will be activated. The system will give a visual or audible warning, or send a notification to the operator's device to remind them to check and handle the problem. After receiving the warning, the operator needs to check the status of the lubricating oil addition system, analyze the cause of the abnormality, and take repair measures. The system may provide troubleshooting guides or automatically adjust settings to deal with the abnormality. The recorded historical data can be used for subsequent analysis to help optimize the lubricating oil addition process and maintenance strategy, and improve the long-term reliability and efficiency of the system. The monitoring system 5 monitors the addition amount and time of lubricating oil in real time to ensure that the system operates normally according to the set requirements.

[0083] Embodiment 4:

[0084] This embodiment provides an elevator lubricating oil addition device, which, in addition to including the technical solution of the above embodiment, further has the following technical features.

[0085] As Figure 1 、 Figure 2 and Figure 5 shown, in this embodiment, preferably, it further includes a feeding mechanism 6, and the feeding mechanism 6 includes:

[0086] A feeding pipe 61 is arranged on the top of the oil storage barrel 1, and the feeding pipe 61 extends downward to penetrate the oil storage barrel 1;

[0088] A sealing cover 63 is arranged on the inner top of the feeding barrel 62;

[0089] A handle 64 is arranged on the top of the sealing cover 63;

[0090] A liquid level sensor 65 is arranged on the front side of the oil storage barrel 1. The liquid level sensor 65 is electrically connected to the processing module 372 and is used to detect the oil storage amount of the lubricating oil in the oil storage barrel 1 and send the detected information to the processing module 372;

[0091] The output end of the electric pump 66 is connected to the feeding pipe 61. The electric pump 66 is electrically connected to the input module 371 and the processing module 372. The processing module 372 controls the working state of the electric pump 66 according to the detected oil storage amount of the lubricating oil in the oil storage barrel 1 by the liquid level sensor 65.

[0092] In this technical solution, the liquid level sensor 65 is installed on the front side of the oil storage barrel 1 for real-time detection of the liquid level of the lubricating oil. The sensor continuously monitors the oil amount and sends the data to the processing module 372. The processing module 372 receives the oil amount data from the liquid level sensor 65. According to the set oil amount range and threshold, the processing module 372 analyzes whether feeding is required. If the processing module 372 determines that the lubricating oil amount in the oil storage barrel 1 is lower than the preset lower limit value, it will send a signal to start the electric pump 66. The electric pump 66 conveys the lubricating oil from the feeding barrel 62 through the feeding pipe 61 into the oil storage barrel 1 to ensure that the lubricating oil can smoothly flow into the oil storage barrel 1. During the feeding process, the liquid level sensor 65 continues to monitor the liquid level of the lubricating oil in the oil storage barrel 1 in real time. The processing module 372 adjusts the working state of the electric pump 66 according to the real-time data to ensure that the lubricating oil amount is within a reasonable range and avoid overfeeding or underfeeding. When the oil amount in the oil storage barrel 1 reaches the set upper limit value, the processing module 372 will stop the working of the electric pump 66 to complete the feeding process. At this time, the lubricating oil supply in the feeding barrel 62 and the connection of the feeding pipe 61 are kept sealed to prevent lubricating oil leakage. The user can open the sealing cover 63 through the handle 64 to add lubricating oil to the feeding barrel 62. The design of the sealing cover 63 ensures that there is no lubricating oil leakage during the operation and at the same time protects the lubricating oil in the feeding barrel 62 from being polluted.

By fitting the mounting plate 72 to the elevator guide rail, passing bolts through the positioning holes 73, and then tightening the bolts, the mounting plate 72 is fixed at the specified position to ensure that the device stably adds lubricating oil to the elevator guide rail.
