Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment lubrication technology, and in particular to an automatic lubrication device for steam curing trolley wheels. Background Technology

[0002] In the aerated concrete panel and block industry, autoclaving trucks serve as crucial transportation tools, undertaking the key task of transporting semi-finished and finished products. These trucks not only need to carry heavy molds exceeding 15 tons but also operate continuously for over 12 hours under high temperature and pressure to complete the autoclaving process. During this process, the wheel bearings of the autoclaving truck operate under extremely harsh conditions, constantly subjected to high loads, high temperatures, and high pressures. Insufficient lubrication can easily lead to accelerated wear, affecting their service life and operational stability. To ensure the durability and reliability of the autoclaving truck wheel bearings, it is essential to increase the frequency of lubrication to reduce frictional loss and extend bearing life.

[0003] However, in existing technologies, the lubrication of wheel bearings in steam-cured vehicles typically relies on manual operation. This method has several drawbacks: firstly, manual lubrication is inefficient and cannot meet the demands of high-frequency lubrication; secondly, manual operation is prone to errors such as missed or incorrect lubrication, which can lead to bearing damage or even equipment failure, resulting in economic losses. Furthermore, manual lubrication lacks precise control, making it impossible to guarantee consistent lubrication amounts each time, potentially leading to unstable lubrication results or resource waste.

[0004] To address the aforementioned issues, there is an urgent need for a device capable of automated and precise lubrication to improve lubrication efficiency and reduce the risk of human error. Currently, although some industries have begun to experiment with automatic lubrication devices, these devices still have certain limitations in practical applications. For example, they lack coordinated control with the steam curing vehicle's operating process, and cannot achieve precise positioning and program interlocking of the lubrication process. This can lead to conflicts between the lubrication process and the steam curing vehicle's transportation operations, affecting production efficiency. Therefore, developing an auxiliary lubrication device that can seamlessly integrate with the steam curing vehicle's operating process and possesses precise positioning and automatic control functions has significant practical importance and application value. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic lubrication device for the wheels of a steam-curing trolley, which solves the problems mentioned in the background art.

[0006] This utility model is implemented as follows: an automatic lubrication device for steam-curing trolley wheels. This automatic lubrication device mainly consists of a positioning device, a sensor mounted on one side of the positioning device, and a lubrication mechanism mounted above the positioning device. The positioning device is the main structure, and both the sensor and the lubrication mechanism are mounted on it. The lubrication mechanism is connected to an oil tank via a solenoid valve. The solenoid valve controls the opening and closing of the oil circuit, ensuring that lubricating oil is accurately injected into the steam-curing trolley wheel bearings. The solenoid valve has a compressed air passage, and an air pressure regulator connected to the compressed air passage is located on the outside of the solenoid valve. The air pressure regulator adjusts the compressed air pressure to ensure a stable and uniform lubricating oil output. The oil tank has an air inlet matching the compressed air passage, which, in conjunction with the compressed air passage, enables efficient delivery of lubricating oil to the lubrication point.

[0007] The positioning device includes a base, a limiting block mounted on the base, and a signal transmitter mounted on one side of the base. The limiting block is used to fix the position of the steam curing cart, forming a stable refueling point. The bottom signal transmitter triggers the subsequent refueling process by detecting the arrival of the steam curing cart, avoiding operational errors caused by manual intervention. The base has a guide groove, the position of which corresponds to the wheels of the steam curing cart, allowing the wheels of the cart to accurately enter the guide groove for positioning. The signal transmitter is L-shaped, its structural design similar to the end effector of an industrial robotic arm, facilitating flexible adjustment of the detection angle. The limiting block has an arc-shaped groove on the side away from the base, and the surface of the arc-shaped groove is coated with a wear-resistant coating. The arc-shaped groove and the wear-resistant coating ensure a tighter contact between the limiting block and the wheels of the steam curing cart and reduce wear.

[0008] This utility model discloses an automatic lubrication device for the wheels of a steam curing trolley. It has a compact structure and low cost, and can be widely used in the aerated concrete panel and block industry. The positioning device can accurately position the steam curing trolley, and the synergistic effect of compressed air and solenoid valves can achieve a stable supply of lubricating oil. This not only significantly improves lubrication efficiency, but also eliminates the problems of missed or incorrect lubrication during manual operation, thereby extending the service life of the wheel bearings of the steam curing trolley and improving production efficiency.

[0013] The specific implementation method of the automatic lubrication device for steam curing trolley wheels of this utility model is described in conjunction with the appendix. Figure 1 and attached Figure 2 A detailed explanation is provided below. This device mainly consists of a positioning device 1, a sensor 2, a refueling mechanism 3, a solenoid valve 4, an oil tank 5, a compressed air passage 6, and a pressure regulator 7. Through a rational layout and design, each component achieves precise positioning and efficient lubrication of the wheel bearings of the steam curing vehicle. The following will elaborate on the implementation of this device from three aspects: overall structure, operating principle, and practical application scenarios.

[0014] like Figure 1 As shown, the positioning device 1 is the core component of the entire device, mainly consisting of a base 8, a limiting block 9, a signal transmitter 10, and a guide groove 11. The base 8, as the basic support component, is made of high-strength steel plate to ensure sufficient stability and load-bearing capacity during long-term use. The limiting block 9 is mounted on the base 8 to fix the position of the steam curing cart. An arc-shaped groove 12 is provided on the side of the limiting block 9 away from the base 8, and the surface of the arc-shaped groove 12 is coated with a wear-resistant coating 13. This design not only allows the limiting block 9 to fit tightly against the wheels of the steam curing cart but also significantly improves the service life of the limiting block 9. The wear-resistant coating 13 is made of high-polymer composite material, possessing excellent wear resistance and maintaining good performance even under high-frequency use conditions. The guide groove 11 is located on the base 8, its position corresponding to the wheels of the steam curing cart. When the steam curing cart enters the working area, the wheels slide along the guide groove 11 to the limiting block 9 for positioning. This design avoids errors caused by manual intervention and improves positioning accuracy. The signal transmitter 10 is L-shaped and mounted on one side of the base 8. Its structure is similar to the end effector of an industrial robotic arm, allowing for flexible adjustment of the detection angle. The signal transmitter 10 triggers the subsequent refueling process by detecting whether the steam curing cart is accurately positioned, thereby achieving automated operation.

[0015] Sensor 2 is located on one side of the positioning device 1 to monitor the position of the steam curing cart in real time. Sensor 2 is a photoelectric sensor, characterized by high sensitivity and fast response, capable of quickly sending a signal after the steam curing cart enters the predetermined position. Sensor 2 works in conjunction with the signal transmitter 10; once the steam curing cart is fully inside the guide groove 11 and fixed by the limit block 9, sensor 2 sends a signal to the control system, notifying it to initiate the refueling process. This design effectively avoids operational errors caused by human negligence and also improves work efficiency.

[0016] The refueling mechanism 3 is positioned above the positioning device 1. Its core components include a solenoid valve 4, a compressed air passage 6, a pressure regulator 7, and an oil tank 5. The solenoid valve 4 is connected to the oil tank 5 via a pipe, controlling the delivery of lubricating oil. The solenoid valve 4 contains a compressed air passage 6, which matches the air inlet 14 on the oil tank 5. By introducing compressed air, it provides power to the lubricating oil, ensuring efficient delivery to the refueling point. The pressure regulator 7 is installed outside the solenoid valve 4 and connected to the compressed air passage 6, used to regulate the pressure of the compressed air. The design of the pressure regulator 7 allows for precise control of the lubricating oil output according to actual needs, thereby ensuring the stability and uniformity of the lubrication process. In practical applications, the pressure regulator 7 can be set to an appropriate pressure value according to the lubrication requirements of the wheel bearings of the steam-cured vehicle. For example, in the initial stage, the pressure can be set to 0.2 MPa to ensure slow lubrication, while in subsequent stages, the pressure can be appropriately increased to 0.4 MPa to accelerate the lubrication process.

[0017] The oil tank 5 serves as a storage container for lubricating oil, and its capacity can be adjusted according to actual production needs. The oil tank 5 is made of Q345R carbon steel and features an oil level display on one side for easy monitoring of the remaining lubricating oil level. Furthermore, the oil tank 5 is equipped with an internal filter to remove impurities from the lubricating oil, ensuring its purity. The air inlet 14 of the oil tank 5 is matched with the compressed air channel 6, introducing compressed air to create a stable pressure environment, thereby propelling the lubricating oil along the pipeline. This design not only simplifies the lubricating oil delivery process but also significantly reduces the energy consumption of the device.

[0018] During actual operation, when the steam curing cart enters the working area, its wheels slide along the guide groove 11 to the limit block 9 for positioning. At this time, the signal transmitter 10 detects that the steam curing cart has reached the predetermined position and sends a signal to the control system. After receiving the signal, the control system activates sensor 2, which further confirms the position status of the steam curing cart and feeds the information back to the control system. Subsequently, the control system issues a command to open the solenoid valve 4 and simultaneously activates the air pressure regulator 7, which delivers lubricating oil from the oil tank 5 to the refueling mechanism 3 through the compressed air channel 6. Under the action of compressed air, the lubricating oil flows along the pipeline and is finally precisely injected into the lubrication points of the wheel bearings of the steam curing cart. Throughout the lubrication process, the air pressure regulator 7 continuously monitors the pressure of the compressed air to ensure that the oil output remains within the set range. When lubrication is complete, the solenoid valve 4 closes, stopping the delivery of lubricating oil, and the entire process ends.

[0019] To verify the actual effectiveness of the device, we selected an aerated concrete panel manufacturer as the test site. During the test, we installed the device in the operating area of ​​the steam curing truck and tested its lubrication efficiency and stability. The test results showed that the device could complete the lubrication of a single steam curing truck wheel bearing within 20 seconds, which is about 80% more efficient than the traditional manual lubrication method. In addition, due to the coordinated control of the air pressure regulator 7 and the solenoid valve 4, the oil output remained stable, with no leakage or incorrect addition. After three months of continuous operation, the wear of the steam curing truck wheel bearings was significantly reduced, and the service life was extended by about 30%, fully demonstrating the superior performance of the device in practical applications.

[0020] In summary, this utility model's automatic lubrication device for steam-cured trolley wheels, through its rational structural design and efficient operating mechanism, successfully solves the problems of low efficiency and complex operation inherent in traditional lubrication methods. This device not only features a compact structure and low cost, but can also be widely applied in the aerated concrete panel and block industry, providing a reliable lubrication solution for related enterprises.
