Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of anti-reverse fluid devices for gear oil filling, specifically, to an anti-reverse fluid device for gear oil filling. Background Technology

[0002] The gearbox of large road maintenance machinery is the core of power transmission. The quality of gear oil filling during winter maintenance directly determines the reliability of equipment operation, and backflow during filling has long been a pain point in the industry. Meanwhile, in the context of building a low-carbon, environmentally friendly, and resource-saving society, a large number of discarded refrigerators are scrapped due to damaged circulation pipes. Directly recycling or discarding their intact compressors would be wasteful of resources and violate environmental principles. Therefore, converting them into gear oil filling equipment has become an important direction for resource reuse.

[0003] Current gear oil filling systems often use simple pipelines for direct operation, lacking dedicated anti-backflow mechanisms. In winter, the high viscosity of gear oil makes pressure fluctuations in the pipelines during filling prone to causing oil backflow. Backflow not only wastes oil and pollutes the working environment but can also introduce impurities, affecting gearbox lubrication and accelerating component wear. Furthermore, the modified compressor filling equipment lacks anti-backflow design, making it difficult to fully realize its recycling value.

[0004] Therefore, the development of anti-backflow devices for gear oil filling has become an urgent need to solve the backflow problem and promote resource reuse. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a gear oil filling anti-backflow device, which solves the technical problems in the prior art where existing gear oil filling mainly adopts simple pipeline direct operation, lacks a dedicated anti-backflow structure, and the high viscosity of gear oil in winter makes the pipeline prone to pressure fluctuations during filling, resulting in oil backflow.

[0006] According to one aspect, at least one embodiment of this disclosure provides a gear oil filling anti-reverse fluid device, comprising: A base plate and a compressor, wherein the compressor is mounted on the surface of the base plate; The gas tank and the compressed air supply assembly are provided, wherein the gas tank is mounted on the base plate and the compressed air supply assembly is mounted on the gas pipe and the compressor. A support and fixing assembly is disposed between the gas tank and the base plate; The compressed air supply assembly includes an outer cover, which is fixed to the base plate and covers the compressor inside. The compressor outlet is connected to the air tank. An air distribution cover is installed on the outer wall of the air tank and is connected to the outlet of the air tank. Several switch nozzles are installed on the side surface of the air distribution cover.

[0007] As a further technical solution, several of the switch nozzles can be connected to a nail gun, a spray gun and a pressurizing nozzle respectively, a connecting sleeve is provided at the air inlet end of the compressor side surface, and an insertion port is provided on the outer cover side surface.

[0008] As a further technical solution, a housing is inserted into the socket, and a docking tube is provided on the side surface of the housing. One end of the docking tube is inserted into the socket, and a barrier mesh is opened on the surface of the connection between the housing and the docking tube.

[0009] As a further technical solution, the interior of the outer shell can be filled with dry filler, the top of the outer shell has a feeding port, one side surface of the outer shell has an open structure, a filter cover is inserted into the opening of the outer shell, and the top surface of the filter cover can cover the feeding port.

[0010] According to another aspect, in at least one embodiment of the present invention, the support and fixing assembly includes a pair of brackets, both of which are fixed to the surface of the base plate. A pair of sleeves are fitted onto the outer wall of the gas tank, and the sleeves are fixedly connected to each other by bolts. One bottom end of each sleeve is vertically inserted downwards into the upper end of the bracket.

[0011] As a further technical solution, the sleeve and the bracket are fixedly connected by bolts at the insertion connection, the outer cover is provided with a fixing cover, the gas tank is vertically inserted into the fixing cover, and the bottom plate is provided with support legs at the four opposite corners, and the lower end of the support legs is provided with casters.

[0012] As a further technical solution, a push-pull bracket is provided on the surface of the base plate.

[0013] As a further technical solution, one side of the fixed cover has an open structure, and the opening of the fixed cover is located at the connection between the air outlet of the compressor and the air tank.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure solves the problem of easy backflow during traditional simple pipeline filling by using a compressed air supply assembly. The outer casing, filter cover, and drying packing constitute a three-stage air intake purification system. The filter cover intercepts large particulate impurities, the drying packing absorbs moisture from the air, and the mesh prevents packing leakage, ensuring that the air entering the compressor is clean and dry, preventing impurities and moisture from contaminating the gear oil. The gas tank acts as a pressure buffer, storing compressed gas and stabilizing the output pressure, effectively offsetting pipeline pressure fluctuations caused by the high viscosity of gear oil in winter, blocking the backflow path of oil from the source, and reducing oil waste and environmental pollution.

[0015] The compressor is shielded by an outer cover, which not only provides dust and noise protection but also optimizes the equipment layout. The multiple air valves on the air distribution hood are compatible with different filling tools, improving the equipment's versatility. The entire assembly integrates functions such as air intake purification, pressure stabilization and buffering, and anti-backflow, eliminating the need for complex piping connections, simplifying the filling process, and ensuring the stability and cleanliness of gear oil filling, meeting the maintenance needs of gearboxes in large road maintenance machinery.

[0024] like Figures 1-3 As shown, it illustrates a gear oil filling anti-reverse fluid device according to an embodiment of the present disclosure, comprising: A base plate 1 and a compressor 2, wherein the compressor 2 is mounted on the surface of the base plate 1; The gas tank 3 and the compressed air supply assembly are provided. The gas tank 3 is mounted on the base plate 1, and the compressed air supply assembly is mounted on the gas pipe and the compressor 2. A support and fixing component 5 is provided on the gas tank 3 and the base plate 1; The compressed air supply assembly includes an outer cover 4-1, which is fixed to the base plate 1 and covers the compressor 2 inside. The outlet of the compressor 2 is connected to the air tank 3. A gas distribution hood 4-2 is installed on the outer wall of the air tank 3 and is connected to the outlet of the air tank 3. Several switch nozzles 4-3 are installed on the side surface of the gas distribution hood 4-2, which can be connected to a nail gun, a spray gun, and a pressure nozzle 4-3, respectively. A connecting sleeve 4-4 is provided at the air inlet end of the side surface of the compressor 2. The side surface of the outer cover 4-1 has an opening. The device has an insertion port 4-5, into which a housing 4-6 is inserted and connected. A docking tube 4-7 is provided on the side surface of the housing 4-6, with one end of the docking tube 4-7 inserted into the insertion port 4-5. A barrier mesh 4-8 is provided on the surface of the connection between the housing 4-6 and the docking tube 4-7. Dry filler can be inserted into the housing 4-6. A feeding port 4-9 is provided on the top of the housing 4-6. One side surface of the housing 4-6 is open, and a filter cover 4-10 is inserted into the opening of the housing 4-6. The top surface of the filter cover 4-10 can cover the feeding port 4-9.

[0025] In some examples, in order to achieve efficient purification of the air intake of compressor 2 and solve the problems of incomplete filtration and residual moisture affecting gas quality in traditional air intake structures, a compressed air supply component was designed. This component includes a base plate 1 made of welded steel plate with milled surface to ensure flatness. It serves as the mounting carrier for components such as compressor 2 and gas tank 3. It can be fixed to the ground with anchor bolts, providing rigid support for the overall structure and preventing component displacement caused by vibration during compressor 2 operation.

[0026] The outer casing 4-1 is made of cold-rolled steel plate, bent and welded, and fixed to the surface of the base plate 1 with bolts, completely covering the compressor 2, which not only provides dust protection but also reduces operating noise. The inlet 4-5 on the side surface of the outer casing 4-1 is stamped, and the outer casing 4-6 is inserted into the inlet 4-5 through the mating tube 4-7 on the side end with a clearance fit. The mating point is sealed with sealant to prevent unfiltered air from seeping in. The barrier mesh 4-8 at the connection between the mating tube 4-7 and the outer casing 4-6 is stamped, and the hole diameter is adapted to the particle size of the dry packing to prevent the packing from entering the compressor 2 with the airflow.

[0027] The outer shell 4-6 is injection molded from engineering plastic, with an internal cavity for filling with drying packing (such as silica gel desiccant). The top feeding port 4-9 facilitates packing replacement. The filter cover 4-10 inserted at the opening is made of stainless steel filter mesh, which not only filters large particulate impurities in the air but also covers the feeding port 4-9 to prevent packing overflow. The connecting sleeve 4-4 at the air inlet of compressor 2 is sealed to the docking pipe 4-7. During air intake, the air undergoes primary filtration by the filter cover 4-10, moisture absorption by the drying packing, and secondary barrier by the mesh 4-8, achieving clean and dry air intake. This ensures the quality of the gas output from gas tank 3 and prevents impurities and moisture from affecting the gear oil filling effect.

[0028] like Figures 1-3 As shown in the figure, the supporting and fixing assembly 5 in this embodiment includes a pair of brackets 5-1, both of which are fixed to the surface of the base plate 1. A pair of sleeves 5-2 are fitted onto the outer wall of the gas tank 3. The sleeves 5-2 are fixedly connected to each other by bolts. One end of the bottom of the sleeve 5-2 is vertically inserted into the upper end of the bracket 5-1. The insertion connection between the sleeve 5-2 and the bracket 5-1 is fixedly connected by bolts. A fixing cover 5-3 is provided on the surface of the outer cover 4-1. The gas tank 3 is vertically inserted into the fixing cover 5-3. Support legs 5-4 are provided at the four opposite corners of the bottom surface of the base plate 1. The lower end of the support legs 5-4 is provided with a moving wheel 5-5.

[0029] In some examples, in order to achieve stable fixation of the gas tank 3 and flexible movement of the equipment, and to solve the problems of easy loosening and inconvenient movement of traditional fixed structures due to vibration, a support and fixing component 5 was designed. This component includes a base plate 1 as the core load-bearing foundation, with pre-set mounting holes on the surface to provide a precise assembly benchmark for components such as bracket 5-1 and outer cover 4-1, ensuring that the positioning of each component is consistent and improving the overall structural stability.

[0030] A pair of brackets 5-1 are welded from high-strength steel and fixed vertically to the surface of the base plate 1 with bolts. They are symmetrically distributed. The upper end of the bracket 5-1 has a slot, which is precisely inserted into the lower end of the sleeve 5-2 that fits on the outer wall of the gas tank 3. The sleeve 5-2 is made of semi-circular steel plate bent into shape. A pair of sleeves 5-2 are fixed to the outer wall of the gas tank 3 with bolts to form a ring-shaped fixation. The insertion point of the sleeve 5-2 and the bracket 5-1 is then locked with bolts to form a rigid fixing structure, which effectively offsets the vibration generated by the operation of the compressor 2 and prevents the gas tank 3 from shifting.

[0031] The fixing cover 5-3 on the surface of the outer cover 4-1 is welded and fixed to the outer cover 4-1, forming a ring structure. The gas tank 3 is vertically inserted inside, further restricting the radial sway of the gas tank 3. The support legs 5-4 at the four opposite corners of the bottom surface of the base plate 1 are welded and fixed to the base plate 1. They are made of hollow steel pipes, and the lower end is rotatably connected to the moving wheel 5-5 with brakes through bearings. When the brake is locked, the position of the equipment can be fixed. When unlocked, the equipment can be moved to different filling stations, which takes into account both the stability of the fixed position and the flexibility of use, and is suitable for the needs of multi-area operation in the workshop.

[0032] For example, such as Figure 1 As shown, a push-pull bracket 6 is provided on the surface of the base plate 1.

[0033] In some examples, the push-pull frame 6 on the surface of the base plate 1 is welded from high-strength seamless steel pipes and rigidly fixed to the side of the base plate 1 with bolts, forming an inverted U-shaped structure. A non-slip rubber handle is fitted in the middle of the frame, with an ergonomically designed height. Combined with the casters 5-5 at the lower end of the support legs 5-4, the equipment can be easily moved by pushing the handle. When the brake is locked, the handle can also serve as a temporary handrail, improving operational safety and ease of movement.

[0034] For example, such as Figure 2 As shown, one side of the fixed cover 5-3 has an opening structure, and the opening of the fixed cover 5-3 is located at the connection between the air outlet of the compressor 2 and the air tank 3.

[0035] In some examples, the edges of the opening at the mounting cover 5-3 are chamfered to prevent scratching pipelines and operators. The opening size is precisely fitted to the connection between the air outlet of compressor 2 and air tank 3, and an oil-resistant sealing rubber strip is attached to the inside of the opening. During normal use, the rubber strip provides auxiliary fixation at the connection. When maintenance or replacement of connecting pipes is required, it can be operated directly through the opening without disassembling the mounting cover 5-3, improving maintenance efficiency.

[0036] In actual use: Hold the push-pull frame 6 and push the equipment to the designated filling position using the casters 5-5 on the bottom of the base plate 1. Lock the casters 5-5 and the support legs 5-4 to stably support the equipment and prevent shaking. Open the filter cover 4-10 at the opening of the outer shell 4-6 and add dry filler into the outer shell 4-6 through the feeding port 4-9. Cover the filter cover 4-10 to cover the feeding port 4-9. Insert the docking pipe 4-7 of the outer shell 4-6 into the socket 4-5 of the outer cover 4-1 and seal it with the connecting sleeve 4-4 at the air inlet of the compressor 2. Secure the gas tank 3 by wrapping it around a pair of sleeves 5-2. The bottom of the sleeves 5-2 is inserted into the bracket 5-1 of the base plate 1 and locked with bolts. The gas tank 3 is vertically inserted into the fixed cover 5-3 of the outer cover 4-1 for further restriction; connect the air outlet of the compressor 2 to the gas tank 3, select the switch nozzle 4-3 on the gas distribution cover 4-2 according to the filling requirements, and connect the corresponding filling pipeline; start the compressor 2, and the air enters the compressor 2 after primary filtration by the filter cover 4-10, moisture absorption by the drying packing, and secondary filtration by the barrier mesh 4-8. The compressed gas is stored in the gas tank 3 and output stably through the gas distribution cover 4-2, pushing the gear oil to be added along the pipeline. The gas tank 3 buffers pressure fluctuations to prevent oil backflow; after the filling is completed, close the switch nozzle 4-3 and the compressor 2, and release the moving wheel 5-5 to push the equipment to the next work station or storage area.
