Description

Technical Field

[0001] This utility model belongs to the technical field of maintenance equipment and devices, specifically relating to a rapid oil replenishment device and a rapid oil replenishment system. Background Technology

[0002] In various industries, especially in port equipment, speed reducers are key components for power transmission and speed ratio adjustment. On-site speed reducers typically operate under high loads in harsh environments with dust and humidity. To ensure the normal and stable operation of the equipment, common maintenance measures for speed reducers include adding or changing the oil.

[0003] Currently, the common method for adding oil on-site is to open the top cover or oil filler port of the reducer housing and directly add oil using an oil can or hose. This method has the following main problems: The risk of external contamination is high when the cover is opened: opening the top cover or oil filler port exposes the internal oil chamber directly to the outside environment, and surrounding dust, iron filings, and other impurities may be drawn in. Wind or equipment vibration can also more easily bring particulate matter into the housing.

[0004] Operating conditions are poor at night or in emergency situations. Insufficient lighting, confined spaces, and when personnel are in a hurry, it is easier for operations to be incomplete, resulting in more foreign substances being brought in or oil being splashed out.

[0005] Unable to achieve rapid, closed-loop oil replenishment: Traditional oil replenishment methods are limited in speed and cannot be carried out in a closed system, so they cannot meet the requirements of speed and environmental protection in emergency situations where rapid restoration of operation is required.

[0006] Risk of misjudging oil level: When opening the cover to add oil, judging the oil level relies on visual inspection and experience, which can easily lead to overfilling or underfilling. Overfilling will cause the reducer to overheat, while underfilling will result in insufficient lubrication.

[0007] When impurities are mixed into the speed reducer, the main effects are: Particulate contaminants cause wear on the tooth contact surfaces, and long-term accumulation can lead to tooth surface fatigue and pitting. The introduction of impurities can also cause noise in the gear reducer.

[0008] Moisture from the air entering the oil reduces the lubricating film's ability, forms emulsions, accelerates lubricant oxidation, and causes additives to fail; at the same time, the presence of water can lead to localized corrosion of the housing and gears.

[0009] Foreign contaminants and oxidation products can alter the viscosity, acid value, and pour point of oil, reducing lubrication efficiency, shortening oil change intervals, and increasing operating costs.

[0010] Particles and emulsions can also cause localized blockages in the lubrication system, leading to localized overheating or lubrication failure.

[0011] In summary, the traditional open-cover oil filling method for port reducers has significant shortcomings in terms of cleanliness, speed, safety, and environmental protection. In the dusty, salt-sprayed, and high-load working environment of ports, any particles or moisture introduced from the outside, or oil contamination caused by improper operation, will manifest as "accelerated wear—oil degradation—fault escalation—downtime for maintenance," directly affecting the reliability of equipment operation. Utility Model Content

[0012] The purpose of this invention is to address the shortcomings of existing technologies that require opening the oil tank and reducer when changing or replenishing oil in a speed reducer, which allows external impurities and moisture to easily enter the reducer, causing wear and corrosion, and is also inconvenient to operate. This invention provides a rapid oil replenishment device and system.

[0013] The technical problem of this utility model is solved by the following technical solution: A rapid refueling device includes an oil storage device, a refueling nozzle, and an electrical control box. The oil storage device includes a refueling tank and a vent cap, with the vent cap mounted on the refueling tank. The refueling nozzle includes a refueling pump and a quick-connect fitting. The oil outlet of the refueling tank is sealed and connected to the oil inlet of the refueling pump via a refueling pipe. The quick-connect fitting is sealed and connected to the oil outlet of the refueling pump. The refueling pump is electrically connected to the electrical control box, which controls the refueling pump. The fuel tank is equipped with a level gauge to indicate the liquid level inside the tank. The fuel pump is a gear pump, and a fuel tank cover is installed on the top of the fuel tank. A filter is installed on the refueling hose; The exhaust pipe of the vent cap is equipped with a refueling branch, which is connected to the exhaust pipe and has a quick connector. A dustproof device is provided on the quick connector.

[0014] The ventilated cap includes a filter space composed of an upper cover and a lower cover. Ventilation holes are provided on the upper cover and / or the lower cover. A ventilated pipe is located below the lower cover and communicates with the filter space. It also includes a filter layer and a replacement layer, both located within the filter space. The replacement layer includes a protective mesh and solid particles. The solid particles are located within the protective mesh and can chemically react with acid to generate a neutral substance. The protective mesh is opposite to the ventilated pipe. The filter layer filters dust and is located between the filter space and the protective mesh. The solid particles are alumina particles or calcium oxide particles. The upper and lower covers are detachably and fixedly connected. The filter layer is one of foam cotton, oil-absorbing felt, or filter cotton. Oil and water vapor in the vented device connected to the vent cap enter the replacement layer through the vent pipe and the lower cover, then enter the filter layer, and finally exit through the vent holes provided on the upper and / or lower covers. External air enters the replacement layer through the filter layer and then enters the vented device through the vent pipe. It also includes a rain cover, which is located above the cover. The rain cover includes a protective cap and a bracket. The protective cap is higher in the center and lower around the edges, covering the top of the cover. The upper end of the bracket is fixedly connected to the protective cap, and the lower end is fixedly connected to the exhaust pipe through a connecting pipe.

[0015] A rapid refueling system includes the aforementioned rapid refueling device, with a refueling port on the refueling device and a refueling end quick connector on the refueling port. The refueling end quick connector is connected to the refueling gun quick connector to quickly connect the refueling device and the refueling device. The refueling device is equipped with a vent cap, which adopts the aforementioned structure, and the refueling branch is the refueling port of the refueling device.

[0016] This novel rapid oil replenishment device features an independent oil tank and pump, both of which can be easily moved by placing them on a trolley or other mobile tool. Because the pump is connected to the electrical control box, the pumping volume can be controlled, ensuring precise oil replenishment. A quick-connect nozzle is included, and this nozzle remains closed when not in use. Therefore, the entire reducer oil replenishment device is sealed during standby, preventing external impurities from entering and keeping the oil clean.

[0017] The vent cap of this utility model has a refueling branch that serves as a refueling port on its exhaust pipe. A quick connector is provided on the refueling branch. The quick connector is usually in a closed state. Therefore, the device with this vent cap can be connected to refueling devices such as refueling guns through the quick connector on the vent cap. This achieves quick connection while ensuring the sealing of the entire refueling process and preventing contamination of the oil during refueling.

[0018] The utility model's rapid refueling system features quick-connect couplings on both the refueling device and the refueled device side. During refueling, these couplings create a closed oil circuit between the two devices through a plug-in connection. This prevents external contaminants from entering the refueling circuit, achieving closed-loop refueling. It avoids oil contamination caused by opening the refueling cap, ensuring a completely sealed refueling process and preventing the entry of external impurities and moisture. Furthermore, it allows for quick connection and disconnection: quick-connect couplings on both the refueling and refueling sides enable "plug-in connection, pull-out disconnection," ensuring speed and efficiency.

Implementation

[0022] The following section will describe in detail the structure of the rapid oil replenishment device, oil replenishment system, and vent cap of this utility model, taking the oil replenishment of a speed reducer as an example.

[0023] like Figure 1-4As shown, the rapid refueling device of this utility model embodiment includes an oil storage device 100, an electrical control box 6, and a refueling nozzle. The oil storage device 100 includes a refueling tank 1, a refueling tank vent cap 4, and a refueling tank cover 3. The refueling nozzle includes a refueling pump 5 and a refueling nozzle quick connector 8. The refueling tank 1 is usually made of 304 stainless steel, is completely sealed, and can be installed on a repair tricycle. Its size can be customized according to actual conditions. The refueling tank cover 3 is designed on top of the refueling tank 1, with a built-in sealing gasket, and is fastened by fixing bolts, facilitating daily cleaning and maintenance of the refueling tank. The refueling tank vent cap 4 is installed on top of the refueling tank 1 to balance the oil vapor in the refueling tank 1. The oil inlet of the refueling pump 5 is sealed to the oil outlet of the refueling tank 1 through a refueling pipe 7, and the oil outlet of the refueling pump 5 is connected to the refueling nozzle quick connector 8 through a refueling pipe 7. Normally, the refueling nozzle quick connector 8 is a male connector. The refueling pump 5 is electrically connected to the electrical control box 6 and controlled by the electrical control box, which is connected to an external 380V power supply. Ideally, a control valve should be installed on the electrical connection line between the fuel pump and the electrical control box to control the operation of the fuel pump. A fueling branch should be installed on the exhaust pipe of the reducer vent cap 10, and a reducer-side quick connector 9 should be installed on this branch. The reducer-side quick connector 9 is usually a female connector. When refueling is needed, simply connect the fuel nozzle quick connector 8 to the reducer-side quick connector 9 to perform the refueling operation. Ideally, a level gauge 2 should be installed on the side of the fuel tank 1 for easy monitoring of the fuel level. The fuel pump 5 should preferably be a gear-type fuel pump. Ideally, a filter device 12 should be installed on the pipeline 7 connecting the fuel pump and the fuel tank outlet to filter out impurities in the fuel, protecting the fuel pump and reducer. The fuel tank vent cap 4 is used to balance the oil and gas in the fuel tank. The fuel tank cover 3 is used for maintenance, cleaning, and routine sealing.

[0024] This invention's refueling system, with its closed-loop design, revolutionizes existing refueling methods, ensuring visibility and controllability throughout the refueling process. This allows for safer, more environmentally friendly, and cost-effective refueling operations even in harsh environments. The system features an independent refueling tank equipped with a visible level gauge and gear pump, guaranteeing a clean and controllable fuel source while facilitating on-site movement and flexible use, achieving portability. The sealed fuel system prevents leaks and spills; its simple operation reduces the risks of nighttime repairs, making it more environmentally friendly and safer.

[0025] The rapid oil replenishment device and system of this utility model, when refueling, connect the oil tank to the device requiring oil replenishment, such as the speed reducer, by connecting the quick connector of the refueling nozzle and the quick connector of the oil-replenishing end. The whole process is fast and direct. Since the quick connector of the refueling nozzle and the quick connector of the oil-replenishing end are in a closed state when not connected, it has the following advantages: 1. The oil circuit is sealed and leak-free, meeting the requirements for green port construction.

[0026] 2. Fast oil replenishment speed: one-button pumping after connector insertion significantly reduces downtime for emergency repairs.

[0027] 3. The closed oil circuit with a filter ensures the cleanliness of the oil entering the gearbox.

[0028] 4. Easy to operate, can be completed by a single person, quick connector is simple to operate and does not depend on environmental conditions.

[0029] 5. Improved oil cleanliness and better lubrication conditions will extend the lifespan of the equipment.

[0030] 6. Reduce equipment failures, lower overall operation and maintenance costs, extend oil change intervals, avoid oil waste, and reduce equipment overhauls and spare parts replacements caused by contamination.

[0031] The working principle and usage process of this utility model are as follows: (1) Confirm that the oil in the refueling tank meets the equipment requirements; (2) Check the status of the oil window and filter device, and confirm that the power supply of the refueling pump is safe and reliable; (3) Remove the seals on the quick connector of the refueling gun and the quick connector of the reducer end, align the quick connector of the refueling gun with the quick connector of the reducer end set on the breather cap 10 of the reducer, insert and lock it to form a closed oil supply circuit, start the refueling pump, and the oil enters the reducer from the refueling tank through the filter device. The oil and gas mixture discharged by the reducer is filtered through the breather cap (10) and discharged. The maintenance personnel control the flow rate through the refueling gun switch, and can also observe the change of oil volume through the oil window set on the reducer. After the refueling is completed, stop pumping, close the refueling gun valve, quickly disconnect the quick connector, seal the quick connector of the refueling gun and the quick connector of the reducer end to prevent dust from entering the reducer and the refueling gun.

[0032] Preferably, a refueling branch is also provided on the exhaust pipe of the vent cap 4 of the fuel tank, which is connected to the exhaust pipe, and a quick connector is also provided on the refueling branch. Normally, the quick connector is sealed by a dustproof device 11, which can be a dust cover, dust plug, or dust shield, as long as it can block dust. In this way, the fuel tank itself is also in a closed circulating oil circuit, improving the cleanliness of the fuel itself.

[0033] Preferably, the fuel tank vent cap and the gearbox vent cap have the same structure, and are collectively referred to as vent caps. The vent cap preferably has the following structure: it includes a vent cap upper cover 200 and a vent cap lower cover 500. The upper and lower covers are connected by a threaded connection or an insert connection. When an insert connection is used, typically the lower cover is the base and the upper cover is cap-shaped, with the upper cover snapping onto the lower cover. The two are connected by a loose-fitting, plug-in connection. Alternatively, a snap-fit ​​connection can be used, as long as the two are detachable. The upper and lower covers together form a closed but not sealed filtration space 800. The vent holes on the upper and lower covers are preferably evenly distributed on the side walls and top of the upper and / or lower covers. The filtration space includes a displacement layer 400 and a filter layer 300. The displacement layer absorbs water and acidic substances from the air. It comprises solid particles 41 that react chemically with acids and a protective mesh 42 that relatively fixes the solid particles. The solid particles are preferably alumina and calcium oxide, which not only react with acids to generate neutral substances but also absorb water from the air, acting as a dryer. The generated neutral substances are deposited and confined within the protective mesh. The filter layer is located outside the protective mesh in the filtration space between the upper and lower covers of the vent cap. The filter layer can be made of materials such as foam, oil-absorbing felt, or filter cotton that can block dust. The protective mesh is preferably cylindrical, such as a stainless steel mesh. The filter layer is sleeve-shaped and fitted over the protective mesh 42; the two can be in contact or not. The filter layer can also cover the top of the protective mesh. An exhaust pipe 700 is located below the lower cover of the vent cap and communicates with the inner cavity of the filtration space. The exhaust pipe is inserted into the vent cap. Ideally, the vertical centerline of the protective net should be collinear with the centerline of the exhaust pipe, ensuring smoother communication between the exhaust pipe and the outside environment. Solid particles located within the protective net are effectively contained, allowing them to accumulate in a definite volume, height, and diameter or width and length, facilitating good contact with acids and alkalis. A more preferred embodiment includes a rain cover 900 above the top cover. The rain cover comprises a protective cap 901 and a support 902. The protective cap is umbrella-shaped, higher in the middle and lower around the edges. The support, located below the protective cap, includes three pillars. The upper part of each pillar is fixedly connected to the protective cap, and the lower part is fixedly connected to a connecting pipe. The horizontal projection of the protective cap covers both the top and bottom covers, providing further protection.

[0034] This novel rapid oil replenishment device is suitable not only for speed reducers, but also for oil changes and replenishments in devices such as hydraulic couplings and hydraulic stations. These devices that require oil replenishment are collectively referred to as oil replenishment / refilling devices.

Their purpose is to enable those skilled in the art to understand the content and usage of this utility model and implement it accordingly. The scope of this utility model should not be limited to these embodiments alone. Various improvements and variations are possible with this utility model.
