Description

Technical Field

[0001] The utility model belongs to the technical field of oil injection equipment, and specifically relates to an automatic oil injection device for a gearbox. Background Art

[0002] When the gearbox is in use, in order to ensure the normal rotation of the gearbox, engine oil is filled inside. Among them, the use of engine oil has a time limit, and it needs to be replaced after a certain period of use. At present, the main replacement method is to manually open the oil inlet of the gearbox and pour the engine oil into it. When this method is used, it is very easy for dust to enter the gearbox along with the engine oil, thereby affecting its normal use.

[0003] To avoid the occurrence of the above problems, an automatic oil injection device for a gearbox came into being. Among them, this device can save manual oil injection through the automatic oil injection method, which not only saves the physical strength of workers but also avoids dust from entering the gearbox.

[0004] When using the automatic oil injection device, the main principle is to use an oil pump to pump the engine oil in the oil barrel into the gearbox. Among them, when this method is used, since the engine oil is changed only at intervals, and when it is not replaced, the engine oil is stored in the oil barrel. Since the oil barrel communicates with the outside air, to a certain extent, the service life of the engine oil will be reduced. Summary of the Utility Model

[0005] The utility model provides an automatic oil injection device for a gearbox to solve the defects in the prior art.

[0006] The utility model is realized through the following technical solutions:

[0007] An automatic oil injection device for a gearbox includes an oil tank with an open top surface. The middle part of the oil tank is separated into a temporary storage part and an oil delivery part by a partition. The oil delivery part is connected to an oil delivery pipe through an oil pump, and a liquid level gauge is arranged in the oil delivery part. The liquid level gauge is signal-connected to a controller; several through holes and air outlet holes are opened on the top surface of the partition. The mouth of the oil barrel is threadedly connected with an inner pipe that can be inserted into the through hole. The lower end surface of the inner pipe is blocked by a blocking plate, and an oil outlet hole is opened on the blocking plate. A piston plate is arranged directly above the oil outlet hole. A groove is opened upward on the top surface of the blocking plate, and one end of a spring is fixedly connected in the groove. The other end of the spring is fixedly connected to the piston plate, and the piston plate seals the oil outlet hole through the spring. A vertical rod fixedly connected to the piston plate is arranged in the oil outlet hole, a cross rod is fixedly connected in the through hole, a support rod is vertically connected upward to the cross rod, and the support rod is in contact and cooperation with the vertical rod. A driving device is arranged in the temporary storage part, and the oil barrel is driven to move vertically downward through the driving device. The driving device is controlled by the controller.

[0008] When this application is in use, open the lid of the oil barrel, then threadedly connect the inner tube to the mouth of the oil barrel, and then insert the oil barrel together with the inner tube upside down into the through hole. Among them, the piston plate blocks the oil outlet under the action of the spring, so as to prevent the oil in the oil barrel from contacting the outside air. The vertical rod is opposite to the support rod. When the liquid level gauge detects that the oil in the oil delivery part is insufficient, the liquid level gauge transmits a signal to the controller, and the controller controls the driving device. The driving device drives the oil barrel to move downward. The downward movement of the oil barrel drives the inner tube to move downward. Since the vertical rod is opposite to and contacts the support rod, when the inner tube moves downward, the vertical rod has a tendency to move downward, but the vertical rod cannot move downward under the support of the support rod. Therefore, the vertical rod will push up the piston plate, and the piston plate no longer blocks the oil outlet, and the oil will enter the oil delivery part through the oil outlet to supplement a barrel of oil to the oil delivery part.

[0009] Preferably, the driving device includes an electric telescopic rod. A cross plate is detachably and fixedly connected in the temporary storage part. The fixed end of the electric telescopic rod is fixedly arranged on the cross plate, and the oil barrel moves downward driven by the extension of the movable rod of the electric telescopic rod. The extension of the electric telescopic rod can drive the oil barrel to move downward.

[0010] Preferably, two oil barrels are in a group. A pressing plate is fixedly connected to the movable end of the electric telescopic rod. The pressing plate covers a group of oil barrels, and the electric telescopic rod is located at the middle position of the pressing plate. Thus, two barrels of oil can be injected at one time through one electric telescopic rod, so as to meet the needs.

[0011] Preferably, the upper part of the oil outlet is an upper flared opening that is wider at the top and narrower at the bottom, and the lower part of the piston plate is a frustum shape adapted to the oil outlet. The flared opening can ensure better flow of the oil in the oil outlet, and the frustum shape can achieve better sealing.

[0012] Preferably, the lower part of the oil outlet is a flared opening that is narrower at the top and wider at the bottom, and the upper part of the piston plate is a conical structure with the tip facing upward. The upper part of the piston plate being a conical structure with the tip facing upward can reduce the resistance of the piston plate moving upward and at the same time facilitate the downward flow of oil.

[0013] Preferably, an outer tube is fixedly arranged in the groove. An inner rod is sleeved in the outer tube. The top surface of the inner rod is fixedly connected to the bottom surface of the piston plate. One end of a spring is fixedly connected to the inner wall of the bottom surface of the outer tube, and the other end of the spring is fixedly connected to the bottom surface of the inner rod. It can ensure that the piston plate moves straight up and down.

[0014] Preferably, the opening of the fuel tank is sealed with a cover plate. An air outlet pipe is communicated with the cover plate, and a pipe cap is fixedly arranged above the air outlet pipe. The cover plate can play a role in dust prevention for the oil storage part, thereby improving the overall dust prevention effect.

[0015] The beneficial effects of the present utility model are as follows: When the oil barrel needs to be refueled, the oil can be added to the oil delivery part. When refueling is not required, the oil is stored in the oil barrel and sealed by the piston plate, thereby effectively reducing the contact time between the oil and the air, and then increasing the service life of the oil.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0023] An automatic oil injection device for a gearbox, as Figures 1-3As shown in the figure. It includes an oil tank 1 with an open top surface. The middle of the oil tank 1 is separated into a temporary storage part and an oil delivery part by a partition plate 2. The oil delivery part is connected to an oil delivery pipe through an oil pump, and a liquid level gauge is arranged in the oil delivery part. The liquid level gauge is signal-connected to a controller; several through holes 4 and air vents 5 are opened on the top surface of the partition plate 2. An inner pipe 6 that can be inserted into the through hole 4 is threadedly connected to the barrel mouth of the oil cylinder 3. The lower end surface of the inner pipe 6 is blocked by a blocking plate 7. An oil outlet hole 9 is opened on the blocking plate 7. A piston plate 8 is arranged directly above the oil outlet hole 9. A groove is opened upward on the top surface of the blocking plate 7. One end of a spring is fixedly connected in the groove. The other end of the spring is fixedly connected to the piston plate 8, and the piston plate 8 seals the oil outlet hole 9 through the spring. A vertical rod 10 fixedly connected to the piston plate 8 is arranged in the oil outlet hole 9. A cross rod is fixedly connected in the through hole 4. A support rod 11 is vertically connected upward to the cross rod. The support rod 11 is in contact and cooperation with the vertical rod 10. A driving device is arranged in the temporary storage part. The oil cylinder 3 is driven to move vertically downward by the driving device, and the driving device is controlled by the controller.

[0024] The driving device described above includes an electric telescopic rod 15. A cross plate is detachably and fixedly connected in the temporary storage part. The fixed end of the electric telescopic rod 15 is fixedly arranged on the cross plate. The oil cylinder 3 is driven to move downward by the extension of the movable rod of the electric telescopic rod 15, and the electric telescopic rod 15 is controlled by the controller.

[0025] When this application is in use, the lid of the oil cylinder 3 is opened, then the inner pipe 6 is threadedly connected to the barrel mouth of the oil cylinder 3, and then the oil cylinder 3 together with the inner pipe 6 is inserted into the through hole 4 in an inverted manner. Among them, the piston plate 8 seals the oil outlet hole 9 under the action of the spring, and the closed state is as Figure 3 shown, so as to avoid the oil in the oil cylinder 3 from contacting the outside air. The vertical rod 10 is opposite to the support rod 11. When the liquid level gauge detects that the oil in the oil delivery part is insufficient, the liquid level gauge transmits a signal to the controller, and the controller controls the electric telescopic rod 15 to extend. When the electric telescopic rod 15 extends, the oil cylinder 3 moves downward, and the downward movement of the oil cylinder 3 drives the inner pipe 6 to move downward. Since the vertical rod 10 is opposite to and in contact with the support rod 11, when the inner pipe 6 moves downward, the vertical rod 10 has a tendency to move downward, but the vertical rod 10 cannot move downward under the support of the support rod 11. Therefore, the vertical rod 10 will push up the piston plate 8, and the lifted state is as Figure 2 shown. The piston plate 8 no longer seals the oil outlet hole 9, and the oil then enters the oil delivery part through the oil outlet hole 9 to supplement the whole barrel of oil in the oil delivery part.

[0026] Two oil cylinders 3 are taken as a group. A pressing plate is fixedly connected to the movable end of the electric telescopic rod 15. The pressing plate covers a group of oil cylinders 3, and the electric telescopic rod 15 is located at the middle position of the pressing plate. Thus, two barrels of oil can be injected at one time through one electric telescopic rod 15, so as to meet the requirements.

[0027] The upper part of the oil outlet 9 is an upper flared opening that is wider at the top and narrower at the bottom, and the lower part of the piston plate 8 is a frustum shape adapted to the oil outlet 9. The flared opening can ensure better flow of the engine oil in the oil outlet 9, while the frustum shape can achieve better sealing performance.

[0028] The lower part of the oil outlet 9 is a flared opening that is narrower at the top and wider at the bottom, and the upper part of the piston plate 8 is a conical structure with the tip facing upward. The conical structure of the upper part of the piston plate 8 with the tip facing upward can reduce the resistance of the piston plate 8 moving upward and facilitate oil drainage downward at the same time.

[0029] An outer tube 12 is fixedly arranged in the groove. An inner rod 13 is sleeved inside the outer tube 12. The top surface of the inner rod 13 is fixedly connected to the bottom surface of the piston plate 8. One end of a spring is fixedly connected to the inner wall of the bottom surface of the outer tube 12, and the other end of the spring is fixedly connected to the bottom surface of the inner rod 13. This can ensure that the piston plate 8 moves straight up and down.

[0030] The opening of the fuel tank 1 is sealed by a cover plate 14. An air outlet pipe is connected to the cover plate 14, and a pipe cap 16 is fixedly arranged above the air outlet pipe. The cover plate 14 can play a role in preventing dust from entering the oil storage part, thereby improving the overall dust prevention effect.

[0031] The beneficial effects of the present utility model are as follows: When the oil cylinder 3 needs to be refueled, the engine oil can be added to the oil delivery part by using this application. When refueling is not required, the engine oil is stored in the oil cylinder 3 and sealed by the piston plate 8, so that the contact time between the engine oil and air can be effectively reduced, and thus the service life of the engine oil can be prolonged.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
