The traditional oil injection machine has only one oil pump, and it is difficult to meet the requirements of both rapid oil injection and precise oil injection at the same time. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent multi-parameter control oil injection machine to solve the problem that the traditional oil injection machine is difficult to balance the oil injection efficiency and the oil injection accuracy.

[0004] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0005] An intelligent multi-parameter control oil injection machine includes an oil storage barrel, a filter, a gas-liquid separator, and a pump oil system connected in sequence. The oil storage barrel and the pump oil system are respectively used to connect the oil inlet and the oil outlet of the lubrication system. The pump oil system is used to pump the oil inside the oil storage barrel into the oil inlet of the lubrication system, and the oil storage barrel is used to receive the waste oil discharged from the oil outlet of the lubrication system;

[0006] The pump oil system includes a first reversing valve, a rapid oil injection pump, a micro oil injection pump, and a second reversing valve. The first reversing valve is connected to the gas-liquid separator, the oil inlet of the rapid oil injection pump, and the oil inlet of the micro oil injection pump. The second reversing valve is connected to the oil outlet of the rapid oil injection pump, the oil outlet of the micro oil injection pump, and the oil inlet of the lubrication system. The first reversing valve and the second reversing valve are used to switch the oil circuit, thereby forming a first oil circuit connecting the gas-liquid separator, the rapid oil injection pump, and the lubrication system, and a second oil circuit connecting the gas-liquid separator, the micro oil injection pump, and the lubrication system.

[0007] Further, a liquid level sensor is arranged inside the oil storage barrel, and flow sensors are installed at the oil outlet of the rapid oil injection pump, the oil outlet of the micro oil injection pump, and the oil outlet of the lubrication system. The liquid level sensor and the flow sensors are connected to a controller, and the controller controls the start and stop of the rapid oil injection pump and the micro oil injection pump according to the signals transmitted by the liquid level sensor and the flow sensors.

Each quick-connect male connector corresponds to one quick-connect female connector. The three quick-connect male connectors are respectively connected to the air inlet of the vacuum pump, the oil inlet of the booster pump, and the oil discharge port of the lubrication system. When the three quick-connect male connectors are connected to the three quick-connect female connectors, the air inlet of the vacuum pump is connected to the air extraction pipe, the oil inlet of the booster pump is connected to the filter, and the oil in the oil storage barrel is pumped out. The oil discharge port of the lubrication system is connected to the oil return pipe.

[0012] Furthermore, a positioning plate is connected to the bottom of the oil storage barrel. The positioning plate is a rectangular flat plate, and the three quick-connect female connectors are arranged on the midline of the positioning plate and are equally spaced along the length direction of the positioning plate.

[0013] Furthermore, positioning holes vertically penetrating through itself are provided at the four corners of the positioning plate. The oil storage barrel fixing platform includes four positioning seats. Each positioning seat includes a positioning column. The four positioning columns correspond to the four positioning holes one by one. The positioning column and the positioning hole contact each other prior to the quick-connect male connector and the quick-connect female connector, so that the quick-connect male connector and the quick-connect female connector can be connected to each other under the guidance of the positioning column and the positioning hole.

[0014] Furthermore, each positioning seat further includes a lever cylinder facing the positioning plate, and the lever cylinder is used to press the positioning plate against the positioning seat after the positioning plate falls on the positioning seat.

Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] In order to achieve the purpose of rapid oil injection and precise oil injection, this embodiment provides an intelligent multi-parameter control oil injector, hereinafter referred to as the oil injector.

[0032] Refer to Figure 1 and Figure 2 , the oil injector is installed on a double-layer bracket 11 equipped with universal wheels 12 and a handrail rod 13. The oil injector includes, connected in sequence: an oil storage barrel 14, a filter 15, a gas-liquid separator 17, and an oil pumping system 18. The oil storage barrel 14 and the oil pumping system 18 are respectively connected to the oil inlet and the oil outlet of the lubrication system 4. The oil pumping system 18 is used to pump the new oil inside the oil storage barrel 14 into the oil inlet of the lubrication system 4. The oil storage barrel 14 is used to receive the waste oil discharged from the oil outlet of the lubrication system 4. The waste oil that has been filtered and deaerated is circulated to the lubrication system 4 through the oil pumping system 18.

[0033] Among them, the oil pumping system 18 includes a first reversing valve 181, a fast oil injection pump 182, a micro oil injection pump 183, and a second reversing valve 184. The first reversing valve 181 is connected to the gas-liquid separator 17, the inlet of the fast oil injection pump 182, and the inlet of the micro oil injection pump 183. The second reversing valve 184 is connected to the outlet of the fast oil injection pump 182, the outlet of the micro oil injection pump 183, and the inlet of the lubrication system 4. The first reversing valve 181 and the second reversing valve 184 are used to switch the oil circuit, thereby forming a first oil circuit connecting the gas-liquid separator 17, the fast oil injection pump 182, and the lubrication system 4, and a second oil circuit connecting the gas-liquid separator 17, the micro oil injection pump 183, and the lubrication system 4. The fast oil injection pump 182 and the micro oil injection pump 183 work respectively to achieve the purpose of quickly and accurately pumping lubricating oil into the lubrication system 4.

[0034] Further, the filter 15 and the gas-liquid separator 17 are connected by a booster pump 16. The booster pump 16 is used to increase the speed of the lubricating oil entering the gas-liquid separator 17 and improve the efficiency of gas-liquid separation.

[0035] Further, a vacuum pump 19 is connected to the top of the gas-liquid separator 17 and the top of the oil storage barrel 14. The vacuum pump 19 is used to extract the gas inside the gas-liquid separator 17 and the oil storage barrel 14. Maintaining a low-pressure environment inside the gas-liquid separator 17 can improve the efficiency of gas-liquid separation, and maintaining a low-pressure environment inside the oil storage barrel 14 can accelerate the oil discharge speed of the oil discharge port of the lubrication system 4.

[0036] Further, a liquid level sensor is arranged inside the oil storage barrel 14. The liquid level sensor is connected to a controller, and the controller is used to calculate the oil quantity inside the oil storage barrel 14 according to the liquid level signal transmitted by the liquid level sensor.

[0037] Further, flow sensors are installed at the oil discharge ports of the fast oil injection pump 182, the micro oil injection pump 183, and the oil discharge port of the lubrication system 4. The flow sensors are connected to a controller, and the controller is used to calculate the oil quantity inside the lubrication system 4 according to the flow signals transmitted by the flow sensors, and at the same time control the start and stop of the fast oil injection pump 182 and the micro oil injection pump 183.

[0038] On the other hand, after circulating and filtering the lubricating oil inside the lubrication system 4, new oil needs to be additionally injected to replace the waste oil inside the lubrication system 4. At this time, it is necessary to discharge the residual waste oil inside the oil storage barrel 14 and perform backwashing on the filter 15. This process is time-consuming and it is difficult to empty the oil storage barrel 14 completely.

[0039] In order to improve the oil injection efficiency of the oil injector, in this embodiment, the technical means of directly replacing the oil storage barrel 14 is adopted. The oil storage barrel 14 storing waste oil is removed and replaced with an oil storage barrel 14 storing new oil, thereby saving the oil injection time. For the specific structure, refer toFigure 5 , Figure 6 and Figure 7 .

[0040] Three quick-connect female connectors 141 are provided at the bottom of the oil storage barrel 14. The three quick-connect female connectors 141 are respectively connected to an air extraction pipe 142, a filter 15, and an oil return pipe 143. The air extraction pipe 142 and the oil return pipe 143 are vertically arranged inside the oil storage barrel 14, and the tops of the air extraction pipe 142 and the oil return pipe 143 are higher than the oil storage level of the oil storage barrel 14. The filter 15 is arranged inside the oil storage barrel 14 and is fixedly connected to the oil storage barrel 14.

[0041] The oil filling machine includes an oil storage barrel fixing platform 2. Three quick-connect male connectors 21 are provided on the oil storage barrel fixing platform 2. Each quick-connect male connector 21 corresponds to a quick-connect female connector 141. The three quick-connect male connectors 21 are respectively connected to the air inlet of a vacuum pump 19, the oil inlet of a booster pump 16, and the oil discharge port of a lubrication system 4.

[0042] When the three quick-connect male connectors 21 are connected to the three quick-connect female connectors 141, the air inlet of the vacuum pump 19 is connected to the air extraction pipe 142 to suck gas from the top of the oil storage barrel 14. The oil inlet of the booster pump 16 is connected to the filter 15 to pump out the oil inside the oil storage barrel 14. The oil discharge port of the lubrication system 4 is connected to the oil return pipe 143 to return the waste oil to the inside of the oil storage barrel 14.

[0043] Further, in order to facilitate the staff to replace the oil storage barrel 14, referring to Figure 3 , Figure 4 and Figure 5 , a positioning plate 144 is connected to the bottom of the oil storage barrel 14. The positioning plate 144 is a rectangular flat plate. The three quick-connect female connectors 141 are arranged on the midline of the positioning plate 144 and are equally spaced along the length direction of the positioning plate 144. Positioning holes 145 vertically penetrating through itself are provided at the four corners of the positioning plate 144.

[0044] This design makes the oil storage barrel 14 symmetrical left and right. Thus, when the staff installs the oil storage barrel 14 onto the oil storage barrel fixing platform 2, there is no need to correct the direction of the oil storage barrel 14, thereby reducing the number of working steps.

[0045] The oil storage barrel fixing platform 2 includes four positioning seats. Each positioning seat includes a positioning post 22. The four positioning posts 22 correspond to the four positioning holes 145 one by one. The positioning posts 22 and the positioning holes 145 come into contact with each other before the quick-connect male connectors 21 and the quick-connect female connectors 141, so that the quick-connect male connectors 21 and the quick-connect female connectors 141 can be connected to each other under the guidance of the positioning posts 22 and the positioning holes 145, avoiding damage to the quick-connect male connectors 21 and the quick-connect female connectors 141.

[0046] Further, each positioning seat further includes a lever cylinder 23 facing the positioning plate 144. The lever cylinder 23 is used to press the positioning plate 144 against the positioning seat after the positioning plate 144 lands on the positioning seat, so as to prevent the positioning plate 144 from moving.

[0047] Preferably, the quick oil injection pump 182 uses a pneumatic plunger pump, and the micro oil injection pump 183 uses an electric gear pump.

[0048] Furthermore, since the vibration of the pneumatic plunger pump is relatively large during operation, but the double-layer bracket 11 does not have good anti-vibration performance. In order to reduce the influence of the working vibration of the plunger pump 15 on the double-layer bracket 11 and solve this problem, a plunger pump fixing table 3 is also installed on the double-layer bracket 11.

[0049] Reference Figure 8 , the plunger pump fixing table 3 includes a vertically arranged sliding table 31 and a slider 32 slidably connected to the sliding table 31 vertically. A damper 33 is fixedly connected to the top of the sliding table 31, and the damper 33 abuts against the top of the slider 32. A guide sleeve 34 is fixedly connected to the bottom of the sliding table 31, and a vertically arranged guide post 35 is connected to the bottom of the slider 32. The guide post 35 is slidably connected to the guide sleeve 34, and a spring 36 is sleeved on the guide post 35. The two ends of the spring 36 abut against the slider 32 and the guide sleeve 34 respectively, and the elastic force of the spring 36 drives the slider 32 to abut tightly against the damper 33.

[0050] Among them, a number of threaded holes 321 are provided on one side of the slider 32, and the plunger pump 15 is connected to the threaded holes 321 by bolts. This design transmits the vibration of the plunger pump 15 to the spring 36, and avoids the vibration being directly transmitted to the hand-pushed mobile bracket by repeatedly compressing the spring 36 by the slider 32, and finally eliminates the vibration of the slider 32 through the damper 33.

[0051] Reference Figure 9 , the specific connection method between the slider 32 and the guide post 35 is: a horizontally penetrating slot 322 is provided at the bottom of the slider 32, and an insert block 351 is arranged inside the slot 322. The width of the bottom of the cross-section of the slot 322 is smaller than the width of the top, so that the insert block 351 can only move horizontally along the slot 322, and the insert block 351 and the guide post 35 are integral parts.

[0052] Further, in order to facilitate the adjustment of the initial position and moving stroke of the slider 32.

[0053] Reference Figure 9, a threaded rod 352 is coaxially connected to the bottom end of the guide rod. The diameter of the threaded rod 352 is smaller than that of the guide rod. The bottom end of the threaded rod 352 is exposed outside the guide sleeve 34 and is screwed with a nut 37. The nut 37 abuts against the bottom of the guide sleeve 34. By rotating the nut 37, the staff can compress or relax the spring 36, so as to appropriately adjust the initial position and moving stroke of the slider 32.

The protection scope of the present invention is defined by the claims.
