Description

Technical Field

[0001] This application relates to the field of escalator maintenance technology, specifically to an intelligent and precise long-lasting lubrication device for escalators. Background Technology

[0002] Currently, escalators are a common mode of transportation in public places. Under long-term high-load operation, they are prone to wear and tear, especially in key parts such as sprockets and chains. Lubricating oil is needed to lubricate these key parts, and the lubricating oil needs to be replenished according to the operation of the escalator.

[0003] Currently, escalator lubrication is usually done manually through periodic inspections and manual oiling. This method relies on the experience and skill level of the staff, which carries the risk of missed or false inspections. It also fails to continuously monitor the escalator's operating status and cannot replenish lubricating oil in a timely manner when it is low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an intelligent and precise long-term lubrication device for escalators. This device can monitor the escalator's operating status in real time and automatically replenish lubricating oil to key components such as sprockets and chains when a lack of lubricating oil is detected. This reduces the workload of staff and solves the current problem that lubrication of escalators typically involves regular manual inspection and lubrication, which relies on the experience and skill level of the staff and carries the risk of missed or false detections. It also fails to continuously monitor the escalator's operating status and cannot promptly replenish lubricating oil when it is insufficient.

[0005] To achieve the goal of real-time monitoring of escalator operation and automatic replenishment of lubricating oil to key components such as sprockets and chains when a lack of lubricating oil is detected, thereby reducing the workload of staff, this application provides the following technical solution: an intelligent and precise long-term lubrication device for automatic escalators, comprising a control host, the control host being located on one side of an oil tank, an oil pump being installed inside the oil tank, the oil pump being connected to an oil delivery pipe, one end of the oil delivery pipe extending to the outside of the oil tank, and the other end of the oil delivery pipe being connected to a spray gun, the control host being electrically connected to a sensor module, the sensor module including an infrared thermometer, a vibration sensor, a humidity sensor, and a displacement sensor, the infrared thermometer, vibration sensor, humidity sensor, and displacement sensor being respectively installed at key components such as sprockets and chains of the escalator, and the control host being electrically connected to the oil pump.

[0006] The above solution uses a sensor module to monitor the escalator's operating status. Based on data such as the escalator's operating temperature, humidity of key parts, vibration, and displacement, it determines whether lubricating oil needs to be added. Then, an oil pump, in conjunction with an oil delivery pipe, uses a spray gun to replenish lubricating oil to the escalator's components. This achieves real-time monitoring of the escalator's operating status. When a lack of lubricating oil is detected, it can automatically replenish lubricating oil to key parts such as sprockets and chains, thus reducing the workload of staff.

[0007] Furthermore, a communication interface is provided on one side of the control host.

[0008] The above solution allows for connection to external management systems via the communication interface, facilitating remote monitoring and management.

[0009] Furthermore, the oil pipeline is a rubber hose, and the inner wall of the oil pipeline is coated with a corrosion-resistant coating.

[0010] The above solution allows the oil pipe to be bent, preventing it from affecting the adjustment of the spray gun position. The corrosion-resistant coating on the inner wall of the oil pipe increases its corrosion resistance and extends its service life.

[0011] Furthermore, the sensor module includes a liquid level sensor, which is disposed inside the oil tank.

[0012] The above solution allows for monitoring of the lubricating oil level in the tank using a level sensor, facilitating timely replenishment of the lubricating oil and preventing situations where insufficient lubricating oil in the tank prevents the escalator from being refilled.

[0013] Furthermore, the outer surface of one end of the spray gun is disposed within the inner wall of one end of the support block, and the inner wall of the other end of the support block is hinged to the top of the support assembly via a hinge frame.

[0014] The above solution uses a support component and a support block to support the position of the spray gun, thereby improving the stability of the spray gun during operation.

[0015] Furthermore, the support assembly includes a threaded rod, a threaded sleeve is threadedly connected to the outer surface of the middle part of the threaded rod, a push plate is fitted on the outer surface of the middle part of the threaded sleeve, a swing rod is hinged to one end of the top of the push plate through a hinge frame, and the inner wall of one end of the swing rod is hinged to one side of the support block through a hinge frame.

[0016] The above method involves rotating the threaded sleeve to adjust its position on the threaded rod, and then using a push plate in conjunction with a swing rod to adjust the angle of the support block, thereby adjusting the height of the support block relative to the oil outlet of the spray gun.

[0017] Furthermore, a rotating shaft is provided at the bottom of the threaded rod, the rotating shaft is rotatably mounted on the top of the mounting base, a turbine is provided on the outer surface of the middle part of the rotating shaft, and a worm gear is rotatably mounted on the top of the mounting base via a support frame, the turbine gear meshing with the worm gear.

[0018] The above scheme involves rotating the worm gear to drive the turbine, which in turn drives the threaded rod through the rotating shaft, thereby adjusting the spray gun's orientation angle. This allows the spray gun's angle to be easily adjusted according to usage conditions.

[0019] Furthermore, a collection tray is hinged to one end of the spray gun via a hinge frame, and the collection tray is located below the oil outlet at one end of the spray gun.

[0020] The above solution allows for the collection of lubricating oil dripping from the spray gun outlet using a collection tray, preventing the lubricating oil adhering to the spray gun outlet from dripping randomly into the escalator and affecting the internal working environment of the escalator.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This intelligent and precise long-term lubrication device for escalators monitors the escalator's operating status through a sensor module. Based on data such as the escalator's operating temperature, humidity of key parts, vibration, and displacement amplitude, it determines whether lubricating oil needs to be added. Then, through an oil pump and oil delivery pipe, a spray gun replenishes lubricating oil to the escalator's pipe parts. This achieves real-time monitoring of the escalator's operating status. When a lack of lubricating oil is detected, it can automatically replenish lubricating oil to key parts such as sprockets and chains, reducing the workload of staff. Attached Figure Description

[0029] 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, and 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.

[0030] Please see Figure 1 and Figure 2 This embodiment of an intelligent and precise long-term lubrication device for escalators includes a control host 1, which is located on one side of an oil tank 2. An oil pump 3 is installed inside the oil tank 2, and the oil pump 3 is connected to an oil delivery pipe 4. One end of the oil delivery pipe 4 extends to the outside of the oil tank 2, and the other end of the oil delivery pipe 4 is connected to a spray gun 5. The control host 1 is electrically connected to a sensor module 6, which includes an infrared thermometer 601, a vibration sensor 602, a humidity sensor 604, and a displacement sensor 605. The infrared thermometer 601, vibration sensor 602, humidity sensor 604, and displacement sensor 605 are respectively installed at key parts of the escalator such as sprockets and chains. The control host 1 is electrically connected to the oil pump 3.

[0031] Please see Figure 1 and Figure 2 The control host 1 is equipped with a communication interface 7 on one side. Through the communication interface 7, it can be connected to an external management system for remote monitoring and management.

[0032] Please see Figure 1 and Figure 2 The oil supply pipe 4 is a rubber hose with a corrosion-resistant coating on its inner wall. The rubber hose design of the oil supply pipe 4 allows it to be bent, preventing it from affecting the adjustment of the spray gun 5 position. The corrosion-resistant coating on the inner wall of the oil supply pipe 4 increases its corrosion resistance and extends its service life.

[0033] Please see Figure 2The sensor module 6 includes a liquid level sensor 603, which is installed inside the oil tank 2. The liquid level sensor 603 can monitor the lubricating oil level in the oil tank 2, so that the lubricating oil in the oil tank 2 can be replenished in a timely manner, avoiding the situation where there is too little lubricating oil in the oil tank 2 to replenish the escalator.

[0034] Please see Figure 1 and Figure 3 The outer surface of one end of the spray gun 5 is set inside the inner wall of one end of the support block 8, and the inner wall of the other end of the support block 8 is hinged to the top of the support assembly 9 through a hinge frame. The support assembly 9 and the support block 8 can support the position of the spray gun 5 and improve the stability of the spray gun 5 when it is working.

[0035] Please see Figure 1 and Figure 3 The support assembly 9 includes a threaded rod 901, with a threaded sleeve 902 threadedly connected to the outer surface of the middle part of the threaded rod 901. A push plate 903 is fitted onto the outer surface of the middle part of the threaded sleeve 902. A swing rod 904 is hinged to one end of the top of the push plate 903 via a hinge frame. The inner wall of one end of the swing rod 904 is hinged to one side of the support block 8 via the hinge frame. By rotating the threaded sleeve 902, the position of the threaded sleeve 902 on the threaded rod 901 is adjusted. Then, the angle of the support block 8 is adjusted by the push plate 903 in conjunction with the swing rod 904, so that the height of the oil outlet of the spray gun 5 is adjusted by the support block 8.

[0036] Please see Figure 1 and Figure 4 A rotating shaft 905 is provided at the bottom of the threaded rod 901. The rotating shaft 905 is rotatably mounted on the top of the mounting base 906. A turbine 907 is provided on the outer surface of the middle part of the rotating shaft 905. A worm gear 908 is rotatably mounted on the top of the mounting base 906 via a support frame. The turbine 907 meshes with the worm gear 908. By rotating the worm gear 908, the turbine 907 is driven to rotate, which in turn drives the threaded rod 901 to rotate via the rotating shaft 905. This allows the direction angle of the spray gun 5 to be adjusted, making it easy to adjust the angle of the spray gun 5 according to the usage conditions.

[0037] Please see Figure 1 and Figure 3 One end of the spray gun 5 is hinged to a collection tray 10 via a hinge frame. The collection tray 10 is located below the oil outlet of the spray gun 5. The collection tray 10 can collect the lubricating oil dripping from the oil outlet of the spray gun 5, preventing the lubricating oil attached to the oil outlet of the spray gun 5 from dripping randomly into the interior of the escalator and affecting the internal working environment of the escalator.

[0038] This embodiment presents an intelligent and precise long-term lubrication device for escalators. The sensor module 6 monitors the escalator's operating status and determines whether lubricating oil needs to be added based on data such as the escalator's operating temperature, humidity of key components, vibration, and displacement amplitude. Then, the oil pump 3, in conjunction with the oil delivery pipe 4, uses a spray gun 5 to replenish lubricating oil to the escalator's components. This achieves real-time monitoring of the escalator's operating status and automatically replenishes lubricating oil to key components such as sprockets and chains when a lack of lubricating oil is detected, thus reducing the workload of staff.

[0039] The working principle of the above embodiment is as follows: The spray gun 5 is placed at a key part of the escalator. The position of the support component 9 is fixed by the mounting base 906, thereby fixing the position of the spray gun 5. According to the position of the key part of the escalator, the threaded sleeve 902 is rotated, causing the threaded sleeve 902 to rotate within the inner wall of one end of the push plate 903. The threaded sleeve 902, in conjunction with the threaded rod 901, adjusts the height of the push plate 903, causing the swing rod 904 to swing while driving the support block 8 to swing, thereby adjusting the height of the oil outlet of the spray gun 5 by the support block 8. The worm gear 908 is rotated, driving the turbine 907 to rotate, causing the turbine 907 to drive the threaded rod 901 to rotate through the rotating shaft 905, thereby adjusting the position of the spray gun 5 by the support block 8. The orientation angle is adjusted so that the oil outlet of the spray gun 5 is aimed at the key parts of the escalator. The operating temperature and humidity of the key parts of the escalator are detected by the infrared thermometer 601 and the humidity sensor 604. The vibration sensor 602 and the displacement sensor 605 monitor the operation of the key parts of the escalator and transmit the data to the control host 1. The control host 1 judges the operation of the escalator based on the data. When it is necessary to add lubricating oil to the key parts of the escalator, the control host 1 controls the oil pump 3 to work, so that the oil pump 3 pumps the lubricating oil in the oil tank 2 into the oil supply pipe 4, so that the oil supply pipe 4 supplies oil to the spray gun 5. The spray gun 5 sprays lubricating oil on the key parts of the escalator to replenish the lubricating oil.
