Description

Technical Field

[0001] The invention relates to the field of processing grease detection and sampling, and in particular to a sampling device for lubricating oil detection. Background Art

[0002] Lubricating oil is a general term for lubricants widely used in various mechanical equipment. It is divided into two categories: liquid and grease according to its physical state. Its main function is to reduce friction, reduce wear and dissipate heat and cool. Among common lubricating oils, grease-like lubricants are usually called greases, which are composed of base oil, thickener and a variety of additives, and can effectively reduce loss during use.

[0003] After grease lubricants are produced, their physical and chemical properties, performance and applicability need to be comprehensively evaluated. The testing of grease lubricants usually includes appearance, cone penetration and viscosity. A series of rigorous tests are performed to ensure that the grease can meet the needs of specific application scenarios. Among them, the cone penetration test of grease lubricants is one of the important methods to measure the consistency and hardness of grease.

[0004] Before conducting a grease cone penetration test, it is usually necessary to manually sample the grease to be tested and place it in a corresponding sampling bottle. As the amount of grease in the sampling bottle increases, the sampling bottle needs to be continuously vibrated to ensure the density of the grease inside the sampling bottle. Finally, the mouth of the sampling bottle is manually scraped flat with a scraper or other tool to ensure the cleanliness of the bottle mouth.

[0005] Although the existing sampling method of grease-like lubricating oil is relatively common, it still has some disadvantages. First, when manually sampling the grease-like lubricating oil in the oil storage tank, the sampling position is relatively single. When sampling at different depths, the grease-like lubricating oil at different depths will inevitably be mixed and then contaminated. When manually vibrating the grease-like lubricating oil inside the sampling bottle, the stability of the force applied in multiple directions cannot be guaranteed, and the air inside the grease-like lubricating oil cannot be effectively discharged, and then it is difficult to ensure the compactness of the grease-like lubricating oil inside the sampling bottle. Finally, when manually scraping and cleaning the mouth of the sampling bottle with tools such as scrapers, it is difficult to avoid a small amount of grease-like lubricating oil remaining at the mouth of the sampling bottle, and therefore the flatness and surface cleanliness of the bottle mouth after sampling cannot be guaranteed.

[0020] Compared with the prior art, the embodiments of the present invention provide the following beneficial effects:

[0021] 1. The present invention realizes the sampling of grease-like lubricating oil at different depths inside the oil storage tank through three oil extraction pipes at different heights. The one-way valve principle is adopted to effectively reduce the probability of the grease-like lubricating oil being contaminated during the sampling process. Different oil delivery pipes are replaced in each sampling work. After the sampling is completed, the grease-like lubricating oil inside the oil extraction pipe is pushed back into the oil storage tank through the movement of the push plug, so as to avoid the grease-like lubricating oil being left in the oil extraction pipe for a long time and contaminating the next sampling sample.

[0022] 2. In the sampling of grease-like lubricating oil, the present invention causes the sampling bottle to rock back and forth at a uniform speed through the reciprocating rotation of the cam in coordination with the arc-shaped matching block, thereby effectively removing the air between the grease-like lubricating oil in the sampling bottle and improving the density of the grease-like lubricating oil in the sampling bottle. The movement of the scraper is coordinated to realize the reciprocating scraping of the mouth of the sampling bottle, thereby improving the flatness and neatness of the mouth of the sampling bottle. At the same time, after the scraper scrapes off the excess grease-like lubricating oil, it is quickly collected by the scraper, thereby avoiding the grease-like lubricating oil remaining on the surface of the scraper for a long time, thereby causing pollution to the grease-like lubricating oil in the sampling bottle.

[0037] The following will Figure 1-13 further elaborate on this application in detail.

[0038] Please refer to Figure 1 , a sampling device for lubricating oil detection, including an L-shaped support base 1. There are two L-shaped support bases 1 which are distributed in the front-back direction. An oil storage tank 11 for storing lubricating oil is supported between the two L-shaped support bases 1. A material pumping mechanism 2 for pumping lubricating oil at different heights is installed on the oil storage tank 11.

[0039] Please refer to Figure 1 and Figure 2 , the material pumping mechanism 2 includes three material pumping pipes 21 with different heights and telescopic sleeves at the upper ends. A material pumping oil pump 211 is arranged on the material pumping pipe 21. The three material pumping pipes 21 are respectively inserted into the oil storage tank 11 and divide the oil storage tank 11 into upper, middle and lower three oil pumping areas. Disposable oil delivery pipes 212 are respectively inserted on the three material pumping pipes 21. An adjusting part 22 is also commonly installed on the three material pumping pipes 21.

[0040] Please refer to Figure 1 , Figure 6and Fig. 9 Below the oil delivery pipe 212, a supporting mechanism 3 for containing lubricating oil is arranged in cooperation. The supporting mechanism 3 includes a U-shaped support 31 with an opening facing downwards. A supporting part 32 is arranged on the U-shaped support 31. Three sampling bottles 33 corresponding to the three oil delivery pipes 212 one by one are arranged in the supporting part 32. A scraping mechanism 4 is arranged between the sampling bottle 33 and the oil delivery pipe 212. Below the supporting part 32, a vibrating part 34 for driving the sampling bottle 33 to vibrate is arranged.

[0041] Please refer to Figure 1 The scraping mechanism 4 includes a scraping part 41 arranged between the oil delivery pipe 212 and the sampling bottle 33 and used for scraping the lubricating oil at the bottle mouth of the sampling bottle 33. A second driving part 42 for driving the scraping part 41 to move reciprocally is arranged on the scraping part 41.

[0042] During specific operation, first, three disposable oil delivery pipes 212 are manually inserted into the corresponding oil extraction pipes 21. At the same time, three sampling bottles 33 corresponding to the oil delivery pipes 212 are placed on the U-shaped support 31, and the sampling bottles 33 are adaptively clamped and limited through the supporting part 32 to ensure that the sampling bottles 33 do not shake. Subsequently, the adjusting part 22 in the oil pumping mechanism 2 is controlled to open the oil extraction pipe 21, and the lubricating oil inside the oil storage tank 11 is sucked up by the oil pump 211.

[0043] The sucked lubricating oil gradually falls into the sampling bottles 33 on the U-shaped support 31 through the oil extraction pipe 21 and the oil delivery pipe 212. When the lubricating oil in the sampling bottles 33 is injected to a certain height, the vibrating part 34 is controlled to work and drive the supporting part 32 and the sampling bottles 33 to vibrate, so as to reduce the bubbles among the lubricating oil in the sampling bottles 33 and ensure the uniformity of the lubricating oil during the injection process.

[0044] While the lubricating oil is vibrating, the second driving part 42 drives the scraping part 41 to move reciprocally to complete the scraping work of the lubricating oil at the bottle mouth of the sampling bottles 33, ensuring the flatness and density of the lubricating oil in the sampling bottles 33. Finally, when the lubricating oil in the three sampling bottles 33 is all injected and the bottle mouths are scraped smoothly, the sampling bottles 33 are synchronously pulled out and detected in cooperation with external detection equipment.

[0045] It should be noted that the three oil extraction pipes 21 at different heights in the oil storage tank 11 can complete the extraction and sampling work of lubricating oil at different heights, improving the accuracy of the later detection results and making them more persuasive.

[0046] Please refer to Figure 1 、 Figure 7 and Fig. 9, a support bracket 311 is fixedly arranged on the left side wall of the C-shaped support frame 31, a support plate 312 is fixedly arranged on the side walls of the two vertical sections of the C-shaped support frame 31 close to each other, strip-shaped plates 313 are respectively fixedly arranged on the side walls of the two vertical sections of the C-shaped support frame 31 close to each other and above the support plate 312, three circular through grooves 314 are arranged on the upper end surface of the horizontal section of the C-shaped support frame 31 in the front-back direction, and an avoidance groove 315 for pushing the sampling bottle 33 is arranged on the left side of each circular through groove 314 and communicated with it.

[0047] Please refer to Figure 7 and Figure 8 , the supporting part 32 includes a supporting circular plate 321 fixedly arranged inside the circular through groove 314 through a plurality of springs, an annular sleeve 322 with a notch opened on the left side is fixedly arranged on the upper end surface of the supporting circular plate 321, the side wall of the notch of the annular sleeve 322 is provided with a chamfer, two arc-shaped clamping rings 323 connected by a torsion spring are installed on the inner wall of the annular sleeve 322, the outer walls of the two arc-shaped clamping rings 323 are fixedly connected with the annular sleeve 322 through a plurality of springs, the arc-shaped clamping rings 323 are also provided with notches with chamfers on both sides at the positions corresponding to the notches of the annular sleeve 322, and the sampling bottle 33 is located between the two arc-shaped clamping rings 323.

[0048] During specific operation, first, three disposable oil delivery pipes 212 are manually inserted into the corresponding oil extraction pumps 211 respectively so that the oil delivery pipes 212 are located inside the oil extraction pipes 21. At the same time, the three sampling bottles 33 slide along the support bracket 311 and the avoidance groove 315. When the sampling bottle 33 slides on the support circular plate 321, the sampling bottle 33 will push the two arc-shaped clamping rings 323 to open to both sides. At this time, the two arc-shaped clamping rings 323 gradually adapt to the diameter of the sampling bottle 33 by compressing the springs on the outer walls. As the sampling bottle 33 moves to the central position between the two arc-shaped clamping rings 323, the self-adaptive clamping work of the sampling bottle 33 is completed through the reaction force of the torsion spring and the springs on the outer walls of the two arc-shaped clamping rings 323, ensuring that the sampling bottle 33 will not shake due to external forces when lubricating oil is injected.

[0049] Please refer to Figure 1 and Figure 2 , the L-shaped support base 1 is divided into a vertical installation section and a horizontal support section. A connecting plate 12 is fixedly arranged between the two installation sections. The side walls of the two support sections close to each other are set as arc-shaped sections, and an oil storage tank 11 is placed between the two arc-shaped sections. Three L-shaped abutting blocks 13 for preventing the oil extraction pipes 21 from tilting are fixedly arranged on the upper end surface of the oil storage tank 11 corresponding to the three oil extraction pipes 21.

[0050] Please refer to Figure 2 and Figure 4The pumping mechanism 2 includes a forward and reverse motor 213 fixedly arranged on the upper end surface of the oil storage tank 11 with the output shaft facing upward. The output shaft of the forward and reverse motor 213 is fixedly provided with an incomplete gear 214. The upper end surface of the oil storage tank 11 is also rotatably provided with a threaded rod 215 through a bearing. The threaded outer wall of the threaded rod 215 is threadedly connected with an arc plate 216, and the outer wall of the non-threaded part of the threaded rod 215 is fixedly provided with an adjusting gear 217 that is always meshed with the incomplete gear 214.

[0051] Please refer to Figure 4 and Figure 5 The regulating part 22 includes a sealing plug 221 which is fixedly arranged inside the oil extraction pipe 21 and has a conical groove 2211 in the center. A conical plug 222 for assisting the sealing plug 221 in sealing is installed inside the conical groove 2211. A push plug 223 for returning excess lubricating oil inside the oil extraction pipe 21 to the oil storage tank 11 is also slidably arranged inside the oil extraction pipe 21. The push plug 223 is fixedly connected to the conical plug 222 by a telescopic rod 224, and the upper end of the push plug 223 is fixedly connected to the arc plate 216 by a round rod 225.

[0052] Please refer to Figure 7 , Fig. 9 and Fig.10 The vibration part 34 includes four arc-shaped matching blocks 341 fixedly arranged on the lower end surface of the supporting circular plate 321 and distributed in the circumferential direction. The circumferential inner walls of the four arc-shaped matching blocks 341 are all provided with a plurality of rollers rotatably arranged along the circumferential direction. A cam 342 is also rotatably arranged on the lower end surface of the supporting circular plate 321 and located between the four arc-shaped matching blocks 341. The lower end surface of the cam 342 is fixedly connected with a connecting shaft. The outer walls of the front and rear connecting shafts are fixedly provided with driven pulleys 343 in an up-and-down staggered manner. The outer wall of the middle connecting shaft is fixedly provided with a driving pulley 344 corresponding to the front and rear driven pulleys 343. The two driving pulleys 344 are respectively connected to the corresponding driven pulleys 343 on both sides through two synchronous belts 345. The connecting shafts on the front and rear sides are respectively connected to the corresponding strip plates 313 in rotation. A No. 2 motor 346 is fixedly arranged on the upper end surface of the supporting plate 312 and located directly below the middle connecting shaft. The output shaft of the No. 2 motor 346 is fixedly connected to the middle connecting shaft.

[0053] After the disposable oil delivery pipe 212 and the sampling bottle 33 are both installed, start the forward and reverse motor 213 to drive the incomplete gear 214 to engage with the adjusting gear 217, causing the second threaded rod 215 to rotate. When the second threaded rod 215 rotates, the arc plate 216 drives the three push plugs 223 to move synchronously through the round rod 225. When the push plugs 223 move upward, they drive the conical plug 222 to move upward through the telescopic rod 224 and separate from the sealing plug 221. Then start the oil pump 211 and pump the lubricating oil at three different heights in the storage tank 11 along the gap at the bottom of the oil suction pipe 21. At this time, the pumped lubricating oil falls into the corresponding sampling bottle 33 along the oil delivery pipe 212.

[0054] When the lubricating oil in the sampling bottle 33 reaches a certain height, start the second motor 346, and the second motor 346 drives the connecting shaft in the middle and the cam 342 to rotate. At the same time, the cams 342 on both sides rotate synchronously driven by the synchronous belt 345. When the three cams 342 rotate synchronously, they intermittently push the arc-shaped mating blocks 341 below their respective supporting circular plates 321. The arc-shaped mating blocks 341 reciprocate and shake, thereby driving the supporting circular plates 321 and the corresponding sampling bottles 33 to vibrate. By driving the sampling bottles 33 to vibrate, the bubbles in the lubricating oil are discharged, ensuring the uniformity of the lubricating oil in the sampling bottles 33, and then facilitating the later inspection work of the lubricating oil.

A telescopic block 4175 is fixed downward inside the mounting slide groove 2 4173, and the telescopic block 4175 is clamped with the matching groove 2 41741 through the telescopic sections at the front and rear ends.

[0058] When the lubricating oil in the three sampling bottles 33 is injected to a certain height, the No. 3 motor 424 is started to drive the adjusting block 425 to rotate. At this time, the adjusting block 425 drives the circular rod 423 and the sliding block 422 to slide along the return groove 4211 through the waist-shaped through groove 4251. When the circular rod 423 and the sliding block 422 slide along the return groove 4211, they drive the mounting block 417 to move synchronously. When the circular rod 423 and the sliding block 422 slide along the horizontal end below the return groove 4211, the scraper 4172 arranged on the mounting block 417 is used to scrape away the excess lubricating oil at the mouth of the sampling bottle 33, thereby ensuring the flatness and cleanliness of the mouth of the sampling bottle 33.

[0059] When the circular rod 423 and the sliding block 422 slide to the rightmost end of the horizontal end below the circular slide groove 4211, the shovel blade 4172 is pushed and matched with the matching end of the auxiliary plate 412, so that the shovel blade 4172 slides and retracts along the installation slide groove 1 4171. During the retraction process, the shovel blade 4172 pushes the pushing block 4174, and the matching groove 2 41741 on the pushing block 4174 is disengaged from the telescopic block 4175. As the shovel blade 4172 continues to slide along the installation slide groove 1 4171, the matching groove 1 41721 gradually slides to the bottom of the telescopic block 4175. At this time, the telescopic block 4175 pops out to reset and is stuck in the matching groove 1 41721, thereby completing the retraction limit work of the shovel blade 4172.

[0060] The adjusting block 425 continues to move the circular rod 423 to rotate. At this time, the sliding block 422 slides along the vertical section on the right side of the circular slide groove 4211. When the mounting block 417 slides upward, it contacts and cooperates with the scraper 413, so that the excess lubricating oil on the mounting block 417 is scraped off to the scraper 413. As the sliding block 422 continues to slide, the excess lubricating oil on the scraper 413 will fall freely into the oil storage tank 414 below due to gravity.

[0061] The adjusting block 425 continues to move the sliding block 422 to slide along the return groove 4211. The mounting block 417 gradually moves to the top of the T-shaped auxiliary block 411 when sliding to the left. Then, the mounting block 417 slides downward along the return groove 4211. The push block 4174 is gradually pushed to slide along the second mounting groove 4173 through the cooperation between the bevel of the push block 4174 and the chamfer on the T-shaped auxiliary block 411. During the sliding process, the push block 4174 pushes the matching groove 1 41721 on the scraper 4172 to gradually align with the telescopic block 4175. The two sampling bottles 33 are disengaged from each other until the telescopic block 4175 pops out and fits into the second matching groove 41741. At this time, the scraper 4172 is in an extended state and continues to slide with the sliding block 422 to complete the scraping of excess lubricating oil at the mouth of the sampling bottle 33. When the three sampling bottles 33 are filled with lubricating oil and the lubricating oil at the mouth of the barrel is scraped off and leveled, the electric push rod 415 is controlled to extend and the push plate 416 pushes the three sampling bottles 33 onto the support bracket 311, and then the peripheral detection equipment is controlled to detect the lubricating oil in the three sampling bottles 33.

[0062] Finally, when the inspection work is completed, the forward and reverse motor 213 drives the threaded rod 215 to reverse and causes the arc plate 216 to drive the push plug 223 downward to move. At this time, the telescopic sleeve at the upper end of the oil extraction pipe 21 is compressed. At the same time, the push plug 223 pushes the excess lubricating oil out of the oil extraction pipe 21 when moving downward along the oil extraction pipe 21, thereby preventing the lubricating oil remaining in the oil extraction pipe 21 for a long time from contaminating the inner wall of the oil extraction pipe 21, thereby ensuring the cleanliness of the lubricating oil during each inspection work.
