Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, and in particular to a sampling and testing device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. It is primarily used between two relatively moving objects to reduce friction and wear caused by contact. During the manufacturing process, lubricating oil requires testing of its properties using sampling and testing devices. These devices extract representative oil samples and analyze their physicochemical properties (such as viscosity, moisture content, and acid value) to determine whether the lubricating oil has failed or whether there is a risk of wear on the equipment. Through precise sampling and multi-parameter analysis, lubricating oil sampling and testing devices provide a scientific basis for equipment maintenance.

[0003] In existing technologies, lubricating oil is prone to stratification or precipitation during long-term static storage due to density differences or changes in intermolecular forces. If the oil sample is not thoroughly mixed during sampling, significant deviations in the components of the sample will occur. This uneven distribution of components directly interferes with the accuracy of subsequent test results, thereby affecting the assessment of the degree of lubricating oil performance degradation, equipment wear status, or remaining service life of the oil. Therefore, it is necessary to improve the sampling and testing device for lubricating oil to solve the above problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of a sampling and testing device for lubricating oil, comprising a base 1, a brake caster 5 fixedly connected to the bottom of the base 1, a testing device body 4 fixedly connected to the top of the base 1, a fixed seat 23 fixedly connected to the top of the base 1, a lifting seat 27 slidably connected inside the fixed seat 23, a collection assembly disposed on the lifting seat 27, a fixed rod 28 fixedly connected to the top of the lifting seat 27, a support frame 29 fixedly connected to the top of the fixed rod 28, a first stirring frame 215 rotatably connected inside the support frame 29, a fixed toothed disc 213 fixedly connected to the bottom of the support frame 29, and a second stirring frame rotatably connected inside the first stirring frame 215. 216. A first circular gear 217 is fixedly connected to the second stirring frame 216. A fixed gear disc 213 meshes with the outside of the first circular gear 217. The lubricating oil is detected by the detection device body 4. The hard pipe 212 and the first stirring frame 215 are both moved into the inside of the lubricating oil storage tank. When the first stirring frame 215 stirs the lubricating oil in the lubricating oil storage tank, the two sets of second stirring frames 216 rotate inside the first stirring frame 215 to improve the stirring and mixing effect of the lubricating oil in the lubricating oil storage tank. After sampling, the collection component collects the lubricating oil remaining on the hard pipe 212, the first stirring frame 215 and the second stirring frame 216.

[0024] Please see Figure 1 - Figure 3In this embodiment, the fixed base 23 has a matching groove at the corresponding position of the lifting base 27. The lifting base 27 slides in the groove of the fixed base 23, which limits the lifting base 27 and facilitates the raising and lowering of the support frame 29, thus improving its practicality. Two sets of the first circular gear 217 and the second stirring frame 216 are provided. The two sets of first circular gears 217 and the second stirring frame 216 are symmetrically distributed on the first stirring frame 215. When the first stirring frame 215 rotates, it drives the two sets of first circular gears 217 to rotate inside the first stirring frame 215, improving the mixing effect of the lubricating oil in the lubricating oil storage tank and preventing the lubricating oil from settling. A first motor 21 is fixedly connected to the top of the base 1. A first bevel gear 22 is fixedly connected to the output end of the first motor 21. A second bevel gear 24 meshes with the outside of the first bevel gear 22. A fixed plate 25 is fixedly connected inside the 23. A threaded rod 26 is rotatably connected inside the fixed plate 25. A lifting seat 27 is threadedly connected to the outside of the threaded rod 26. A second bevel gear 24 is fixedly connected to the threaded rod 26. A second motor 214 is fixedly connected to the top of the support frame 29. A first stirring frame 215 is fixedly connected to the output end of the second motor 214. An oil pump 210 is fixedly connected to the top of the support frame 29. A connecting hose 211 is fixedly connected between the oil pump 210 and the detection device body 4. A rigid pipe 212 is fixedly connected to the end of the oil pump 210 away from the connecting hose 211. By moving the rigid pipe 212 and the first stirring frame 215 into the interior of the lubricating oil storage tank, and then stirring the lubricating oil in the lubricating oil storage tank through the first stirring frame 215, the two sets of second stirring frames 216 rotate inside the first stirring frame 215, thereby improving the stirring and mixing effect of the lubricating oil in the lubricating oil storage tank.

[0025] Please see Figure 4 - Figure 5In this embodiment, the collection assembly includes a rotating sleeve 31 rotatably connected to the lifting seat 27, a support rod 32 fixedly connected to the rotating sleeve 31, a placement frame 33 fixedly connected to the end of the support rod 32 away from the rotating sleeve 31, a collection frame 34 disposed inside the placement frame 33, a second circular gear 35 fixedly connected to the rotating sleeve 31, a toothed plate 36 meshing with the outside of the second circular gear 35, a sliding frame 37 slidably connected inside the support frame 29, and a hydraulic telescopic rod 38 fixedly connected to the top of the support frame 29. A fixing plate 25 is fixedly connected to the sliding frame 37, and the sliding frame 37 is fixedly connected to the telescopic end of the hydraulic telescopic rod 38. The collection frame 34 collects the residual lubricating oil on the hard tube 212, the first stirring frame 215, and the second stirring frame 216. After sampling, the collection assembly collects the lubricating oil from the hard tube 212, the first stirring frame 215, and the second stirring frame 216. The residual lubricating oil on the mixing rack 216 is collected to avoid waste and improve the practicality of the device. The lifting seat 27 has a matching groove at the corresponding position of the rotating sleeve 31. The rotating sleeve 31 rotates in the groove of the lifting seat 27, so that the rotating sleeve 31 rises and falls synchronously when the lifting seat 27 rises and falls, thereby improving the stability of the device. The placement rack 33 has a matching groove at the corresponding position of the collection frame 34. The collection frame 34 is placed in the groove of the placement rack 33, making it easy to remove the collection frame 34 from the placement rack 33, thereby improving the processing efficiency of the lubricating oil inside the collection frame 34 and improving the practicality of the device. The support frame 29 has a matching groove at the corresponding position of the sliding frame 37. The sliding frame 37 slides in the groove of the support frame 29, thereby limiting the movement of the toothed plate 36 and improving the stability of the movement of the toothed plate 36.

[0026] During operation, the device is moved to the desired position using the brake casters 5. The extended hydraulic telescopic rod 38 causes the sliding frame 37 to slide within the groove of the support frame 29. The toothed plate 36 meshes with the outside of the second circular gear 35, causing the rotating sleeve 31 to rotate on the lifting seat 27, thus rotating the collection frame 34 away from the rigid pipe 212. Then, the first motor 21 is activated, causing the first bevel gear 22 and the second bevel gear 24 to mesh, driving the threaded rod 26 to rotate inside the fixed plate 25. The lifting seat 27 is threaded to the outside of the threaded rod 26, lowering the support frame 29 and moving both the rigid pipe 212 and the first stirring frame 215 into the lubricating oil storage tank. At this point, the second motor 214 is activated, causing the first stirring frame 215 to rotate inside the support frame 29, stirring the lubricating oil in the storage tank. By fixing the gear plate 213 to mesh with the outside of the two sets of first circular gears 217, the two sets of second stirring frames 216 rotate inside the first stirring frame 215, thus stirring and mixing the lubricating oil in the lubricating oil storage tank to prevent the lubricating oil from settling. Then, the oil pump 210 is started, and the oil pump 210 draws lubricating oil through the rigid pipe 212 and injects the lubricating oil into the detection device body 4 through the connecting hose 211, so that the lubricating oil can be detected. After sampling, the support frame 29 is raised and reset, and the angle of the first stirring frame 215 is reset so that the first stirring frame 215 is parallel to the collection frame 34. By retracting the hydraulic telescopic rod 38, the collection frame 34 is moved to the bottom of the rigid pipe 212 and the first stirring frame 215, so that the lubricating oil remaining on the rigid pipe 212, the first stirring frame 215 and the second stirring frame 216 can be collected, reducing the waste of lubricating oil and improving practicality.

[0027] Through the above steps, by moving both the rigid tube 212 and the first stirring frame 215 into the interior of the lubricating oil storage tank, and then rotating the two sets of second stirring frames 216 inside the first stirring frame 215 while the first stirring frame 215 is stirring the lubricating oil in the storage tank, the mixing effect of the lubricating oil in the storage tank is improved, avoiding the phenomenon of lubricating oil sedimentation, and improving the detection accuracy of the detection device body 4. This solves the problem that during long-term static storage of lubricating oil, its internal components are prone to stratification or sedimentation due to density differences or changes in intermolecular forces, which reduces the accuracy of subsequent detection results.
