Description
Technical Field
[0001] The utility model relates to the field of elevator rail lubrication, in particular to an elevator rail lubrication device with an alarm function. Background Art
[0002] At present, the car guide rails in the vertical lift shafts of commercial office buildings, residential homes, and high-end hotels are in operation. Due to the large mobility of personnel and the high frequency of up and down use, the guide rails rely on the car guide shoes for friction during operation. Lubricants are installed on the upper part of the car guide shoes to reduce the friction coefficient between the guide rails and the guide shoes during elevator operation, thereby improving durability. It is difficult to judge whether the lubricating oil has been consumed during operation, resulting in hard friction between the guide rails and the guide shoes when there is no lubricating oil, which generates noise and affects the riding comfort experience.
[0003] Common elevator rail lubrication equipment only has lubrication function and can lubricate the guide rails, but lacks lubrication detection and alarm functions. It cannot guarantee timely maintenance or adding lubricant. It is easy for the rails to be unable to be lubricated after the lubricant is used up, which reduces the durability of the guide rails and guide shoes and affects their service life.
[0004] Therefore, in view of the fact that the above-mentioned elevator rail lubrication equipment lacks the function of lubrication detection and alarm, an elevator rail lubrication equipment with an alarm function can be designed. By setting an inertial sensor with model number 3DM-GX3-25 to detect the acceleration of the elevator car moving up and down, lubricant can be added only when the elevator car is moving. The liquid level sensor with model number FS-IR1902D detects the lubricant level. If the liquid level is lower than the preset value, the signal is transmitted to the signal system COP control panel to inform the owner or maintenance personnel, who will receive a text message reminder sent by the elevator Internet of Things module, so that personnel can promptly inspect the elevator or add lubricant, thereby ensuring the comfort of the elevator ride.

This solves the problem that common elevator track lubrication equipment only includes lubrication function and can lubricate the guide rails, but lacks lubrication detection and alarm functions. It cannot guarantee timely maintenance or lubricant addition, and it is easy for the track to be unable to be lubricated after the lubricant is used up, thereby reducing the durability of the guide rails and guide shoes and affecting the service life.

A limit frame 7 is provided on the front side of the interior of the lubricant box 1 at the position corresponding to the lubrication slot 6. A connecting plate 16 is connected to the rear ends of the damper 14 and the spring member 15. Four connecting holes 17 are provided at equal intervals at the four corners of the front side of the connecting plate 16. A fixing plate 13 is welded to the rear side of the lubricant box 1.

When the elevator car moves up and down, the inertial sensor 5 with model 3DM-GX3-25 detects the acceleration of the car moving up and down, and then transmits the detected acceleration data to the PLC controller in the elevator room. After receiving the acceleration data, the PLC controller starts the liquid extraction pump 10, and the liquid extraction pump 10 extracts the lubricant in the lubricant box 1 through the liquid extraction tube 12. After the lubricant in the box 1 is extracted, the liquid pump 10 transports the lubricant to the lubricating sponge 8 through the infusion tube 11 to be absorbed. The lubricating sponge 8 evenly applies the lubricant on the track when it moves up and down along the track, ensuring that the friction between the guide rail and the guide shoe is reduced. The liquid level sensor 3 with model FS-IR1902D detects the lubricant liquid level in the lubricant box 1, and then transmits the detected liquid level data to the PLC controller in the elevator room. If the liquid level is lower than the preset value, it is transmitted to the signal system COP control panel through a signal to inform the owner or maintenance personnel who will receive a text message reminder sent by the elevator Internet of Things module, making it convenient for personnel to inspect the elevator or add lubricant in time, thereby ensuring the comfort of the elevator ride, and realizing the function of lubrication detection alarm to prevent the situation where the track cannot be lubricated after the lubricant is used up, thereby reducing the durability of the guide rail and guide shoe and affecting the service life.
[0025] During operation, the lubricating sponge 8 is inserted into the inside of the limit frame 7, and then the inertial sensor 5 with model number 3DM-GX3-25 and the liquid level sensor 3 with model number FS-IR1902D are electrically connected to the PLC controller in the elevator room, and then the connecting plate 16 is fixed to the elevator car with bolts. After the connecting plate 16 is fixed, the spring member 15 pushes the lubricating sponge 8 to move toward the track through the lubricant box 1 until the lubricating sponge 8 fits the track. When the elevator car moves up and down, the inertial sensor 5 with model number 3DM-GX3-25 detects the acceleration of the car's up and down movement, and then transmits the detected acceleration data to the PLC controller in the elevator room. After receiving the acceleration data, the PLC controller starts the liquid pump 10, and the liquid pump 10 pumps the lubricant box through the liquid pipe 12. 1 is extracted. After the lubricant in the lubricant box 1 is extracted, the liquid pump 10 transports the lubricant to the lubricating sponge 8 through the infusion tube 11 to be absorbed. The lubricating sponge 8 evenly smears the lubricant on the track when it moves up and down along the track, ensuring that the friction between the guide rail and the guide shoe is reduced. The liquid level sensor 3 with model FS-IR1902D detects the lubricant level in the lubricant box 1, and then transmits the detected liquid level data to the PLC controller in the elevator room. If the liquid level is lower than the preset value, it is transmitted to the signal system COP control panel through the signal to inform the owner or maintenance personnel who will receive a text message reminder sent by the elevator Internet of Things module, which is convenient for personnel to repair the elevator or add lubricant in time, thereby ensuring the comfort of the elevator ride and realizing the function of lubrication detection alarm.
[0026] Through the above steps, the acceleration of the car moving up and down is detected by setting the inertial sensor 5 with model number 3DM-GX3-25, and then the detected acceleration data is transmitted to the PLC controller in the elevator room. After receiving the acceleration data, the PLC controller starts the liquid pump 10 to input the lubricant into the lubricating sponge 8 to be absorbed. The lubricating sponge 8 fits the track evenly and applies the lubricant on the track. The liquid level sensor 3 with model number FS-IR1902D detects the lubricant level in the lubricant box 1, and then transmits the detected liquid level data to the PLC controller in the elevator room. If the liquid level is lower than the preset value, the signal is transmitted to the signal system COP control panel to inform the owner or maintenance personnel, who will receive a text message reminder from the elevator Internet of Things module, so that the personnel can promptly inspect the elevator or add lubricant to ensure the comfort of the elevator ride. This solves the problem that common elevator track lubrication equipment only includes lubrication function and can lubricate the guide rails, but lacks lubrication detection and alarm functions, and cannot guarantee timely maintenance or lubricant addition. It is easy for the lubricant to be used up and the track cannot be lubricated, thereby reducing the durability of the guide rails and guide shoes and affecting their service life.
