Description

Technical Field

[0001] This utility model relates to the field of lubrication technology for engineering machinery and equipment, and in particular to a high-efficiency and energy-saving oil injection system device for vehicles. Background Technology

[0002] In industrial production, especially in scenarios such as electrolytic aluminum, mining, and construction, loaders, excavators, and other engineering vehicles undertake heavy tasks such as raw material handling, material loading and unloading, and site cleanup. These vehicles operate in harsh environments with high dust levels, intense vibrations, and significant temperature differences for extended periods. Their key moving parts (such as bucket pins, boom pins, rocker arm pins, steering cylinder connections, and drive shafts) wear down much faster than equipment under normal operating conditions due to frequent friction and impact.

[0003] To ensure the stable operation of machinery, the aforementioned key components require regular lubrication with grease to reduce friction loss. Currently, the industry commonly uses manual periodic lubrication, which has the following significant drawbacks: High labor costs and low efficiency: Manual lubrication requires operators to locate each lubrication point and manually press the grease gun to apply grease to different areas. For large machinery, each lubrication session is time-consuming and requires dedicated personnel, consuming production resources; Insufficient lubrication accuracy: Manual lubrication relies on the operator's experience and judgment, easily resulting in over-lubrication (leading to grease waste and contamination) or under-lubrication (failing to form an effective lubricating film), especially for concealed or difficult-to-reach areas. Frequent instances of insufficient or incomplete lubrication at nearby lubrication points exacerbate component wear; poor maintenance timeliness: due to factors such as production planning and personnel arrangements, manual lubrication often results in periodic delays, causing components to continue operating in a lubrication-deficient state, leading to abnormal noises, jamming, or even machine shutdowns, increasing maintenance costs and severely impacting production continuity; weak safety and environmental adaptability: in harsh environments such as dust and high temperatures, manual lubrication not only increases the labor intensity of operators but also poses safety hazards such as slipping and bumping; in addition, grease leakage is prone to occur during manual lubrication, causing pollution to the working environment.

[0004] With the improvement of industrial automation, the requirements for maintenance efficiency, reliability, energy conservation, and environmental protection of engineering vehicles are increasing. Traditional manual lubrication methods can no longer meet the demands of modern production for low failure rates and high utilization rates of equipment. Therefore, developing a system that can achieve precise, automatic, and efficient lubrication has become the key to solving the above problems. Utility Model Content

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with reference to specific embodiments:

[0028] like Figure 1-3 As shown, a high-efficiency and energy-saving oil injection system for vehicles includes:

[0029] High-pressure plunger pump 1 (plate type): As the power source of the system, the high-pressure plunger pump 1 (plate type) is responsible for providing a stable grease output pressure. This pump is an electric plunger pump, characterized by stable pressure, adjustable flow rate, and reliable operation, and can adapt to the lubrication needs of the loader under different working conditions (such as high load or high temperature environment). The high-pressure plunger pump 1 (plate type) is fixed to the loader frame by a bracket to ensure stable operation in vibration environment. The bracket design takes into account vibration resistance to avoid pump body loosening or damage due to equipment movement. The grease storage container is integrated inside the pump body or in an adjacent location, and the liquid level sensor is installed in the container for real-time monitoring of the grease level.

[0030] Controller 2 is fixed below the pressure plate type high-pressure plunger pump 1 and is tightly integrated through mechanical connection and electrical interface. Controller 2 is a programmable logic controller (PLC) with a built-in fault alarm module, capable of precisely controlling the oil injection time, oil injection volume, and oil injection cycle according to a preset program. PLC controller 2 has the following functions: receiving signals from the oil pressure sensor 5 and the level sensor to monitor the system status in real time. When abnormal pressure or low grease level is detected, an alarm signal is automatically triggered to alert the operator. It is compatible with the loader's existing electrical system to avoid interfering with the operation of other equipment. Controller 2 is connected to the solenoid valve 3 and oil pressure sensor 5 via signal line 4 to achieve rapid response control.

[0031] Solenoid valve 3: Located on controller 2, solenoid valve 3 features a fast-response design, capable of receiving signals from PLC controller 2 and achieving instantaneous on / off control of the oil circuit. This ensures timely start and stop of the oil filling process, reduces grease waste, and improves system efficiency. The selection of solenoid valve 3 takes into account the loader's working environment, possessing dustproof and temperature-resistant characteristics to adapt to high dust and temperature variation conditions.

[0032] Single-row, single-line distributor 6: Two single-row, single-line distributors are used, employing a progressive distributor design. The two progressive distributors are interconnected via a main oil pipe 8, which is also connected to the controller 2 and the pressure plate-type high-pressure plunger pump 1. The distributor has a preset lubrication point distribution ratio function, accurately distributing the amount of grease according to the needs of each lubrication point, ensuring that each point receives adequate lubrication and avoiding over- or under-lubrication issues during manual lubrication. The distributor output is connected to the grease injection connectors at each lubrication point via a distribution pipe 7. The grease injection connectors are modified for loader lubrication points (such as bucket pins, rocker arm pins, steering cylinder pins, and drive shafts) to ensure smooth grease delivery and reduce the risk of leakage.

[0033] Oil pressure sensor 5: Located on the single-row, single-wire distributor 6, oil pressure sensor 5 is connected to controller 2 via signal line 4 for real-time monitoring of system pressure. The sensor is equipped with a protective housing that is dust-resistant, vibration-resistant, and temperature-resistant, protecting the sensor for normal operation in harsh environments. When the pressure is abnormal, the sensor signal triggers an alarm in controller 2.

[0034] Piping system:

[0035] Main oil pipe 8: Connects the pressure plate type high-pressure plunger pump 1, controller 2, and single-row single-line distributor 6, responsible for delivering lubricating grease. Main oil pipe 8 is made of high-pressure resistant material to ensure stable operation under system pressure.

[0036] Oil distribution pipe 7: Extends from the single-row single-line distributor 6 to the oil filling joints of each lubrication point. The layout of oil distribution pipe 7 is optimized according to the loader structure to avoid bending or contamination.

[0037] Signal line 4: Connects controller 2, oil pressure sensor 5, level sensor, and solenoid valve 3 to transmit electrical signals. The wiring is designed and equipped with a protective sleeve to prevent electrical faults.

[0038] One-button automatic oiling button 31: Located on controller 2, it is used to trigger the automatic oiling program. Operators simply need to press the button to activate the automatic oiling program. The button has a simple, ergonomic design, facilitating quick operation during equipment downtime.

[0039] Level sensor: The level sensor is installed inside the grease storage container of the pressure plate type high-pressure plunger pump 1 and is electrically connected to the controller 2. The sensor monitors the grease level in real time. When the level is too low, it sends a feedback signal to the controller 2 to trigger an alarm to ensure timely replenishment of grease.

[0040] Working principle:

[0041] The system operates based on a one-click triggering and automatic control mechanism. The specific steps are as follows:

[0042] Start-up phase: The operator presses the one-button automatic oil injection button 31 in the loader cab. The button signal is transmitted to the PLC controller 2 via electrical wiring.

[0043] Pump Start-up and Grease Delivery: After receiving a signal, controller 2 drives solenoid valve 3 to open, simultaneously starting pressure plate type high-pressure plunger pump 1. The pump draws grease from the storage container and delivers it through main oil pipe 8 to single-row single-line distributor 6.

[0044] Distribution and Lubrication: The progressive distributor precisely distributes the grease to each oil distribution pipe 7 according to a preset ratio. The oil distribution pipes 7 deliver the grease to the critical lubrication points of the loader, ensuring that each point receives adequate lubrication.

[0045] Real-time monitoring and alarm: Oil pressure sensor 5 monitors system pressure. If an abnormality is detected, it immediately feeds back to controller 2 via signal line 4, triggering an alarm. The level sensor monitors the grease level. When the level is too low, controller 2 issues an alarm signal, prompting the addition of grease.

[0046] System shutdown: After the oil injection procedure is completed, controller 2 closes solenoid valve 3 and the pump, stopping the oil injection. The entire process is completed in a short time, significantly improving maintenance efficiency.

[0047] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
