DETAILED DESCRIPTION

[0027] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below according to specific implementation methods and in combination with the accompanying drawings.

[0028] Figure 1 A schematic diagram of the structure of an oil pressure plate type electric lubrication pump provided in an embodiment of the present application. The device includes an oil tank 1 and a plunger pump assembly 10, an eccentric wheel assembly 11 and a drive motor 12 arranged at the bottom of the oil tank 1. The drive motor 12 drives the eccentric wheel assembly 11 to rotate, and drives the plunger pump assembly 10 to reciprocate through the eccentric wheel assembly 11, so that the lubricating oil in the oil tank 1 is sent out through the grease outlet to lubricate the equipment.

[0029] See also Figure 1The oil tank 1 is in a hollow cylindrical shape. A top cover is detachably mounted on the upper end of the oil tank 1, and an oil filling port is provided on the top cover. A guide rod 2 is fixedly mounted inside the oil tank 1, and the axis of the guide rod 2 coincides with the axis of the oil tank 1. An oil pressure plate 3 is provided on the outer sliding sleeve of the guide rod 2. The oil pressure plate 3 is sealed and connected to the inner wall of the oil tank 1 through a sealing ring fixedly mounted on the outer wall thereof.

[0030] The guide rod 2 located above the oil pressure plate 3 is sleeved with a first conical spring 8, a spring retainer and a second conical spring 9 in sequence from top to bottom. Figure 1 The upper end of the first conical spring 8 abuts against the top cover of the upper end of the oil tank 1, and the lower end of the first conical spring 8 abuts against the upper end of the spring retainer. The upper end of the second conical spring 9 abuts against the lower end of the spring retainer, and the lower end of the second conical spring 9 abuts against the upper end surface of the oil pressure plate 3.

[0031] The diameter of the upper end surface of the first conical spring 8 is larger than the diameter of the lower end surface, and the diameter of the lower end surface of the second conical spring 9 is larger than the diameter of the upper end surface.

[0032] In the initial state, the oil tank 1 contains a large amount of lubricating oil. At this time, the oil pressure plate 3 is at a high position in the oil tank 1, and the first conical spring 8 and the second conical spring 9 are in a compressed state, which jointly apply downward pressure to the oil pressure plate 3 to ensure that the lubricating oil is at the bottom of the oil tank 1. As the lubricating oil in the oil tank 1 is delivered, the oil pressure plate 3 gradually moves downward under the action of the first conical spring 8 and the second conical spring 9.

[0033] Preferably, a magnetic switch 4 is fixedly installed at the lower part of the guide rod 2. At the same time, a magnetic block 5 is fixedly installed at the upper end of the oil pressure plate 3. When the oil pressure plate 3 moves downward until the magnetic block 5 enters the sensing area of ​​the magnetic switch 4, the magnetic switch 4 generates an alarm signal and transmits it to the controller. After receiving the alarm signal, the controller reminds the operator that the oil level in the oil tank 1 is too low and lubricating oil needs to be added.

[0034] In this embodiment, an annular mounting groove 6 is provided in the middle of the upper end surface of the oil pressure plate 3, the axis of the mounting groove 6 coincides with the axis of the guide rod 2, and the inner side wall of the mounting groove 6 fits the outer side wall of the guide rod 2. The magnetic block 5 is fixedly installed in the mounting groove 6, and the shape of the magnetic block 5 matches the shape of the mounting groove 6, and is also annular. By setting in the above manner, the horizontal distance between the magnetic block 5 and the magnetic switch 4 is reduced as much as possible, thereby ensuring the induction sensitivity of the magnetic switch 4 to the magnetic block 5.

[0035] See also Figure 1 An oil scraper assembly is also provided at the bottom of the oil tank 1, and the oil scraper assembly is drivingly connected to the drive motor 12. The drive motor 12 drives the eccentric wheel assembly 11 to rotate while also driving the oil scraper assembly to rotate, thereby stirring the lubricating oil.

[0036] Preferably, the oil scraper assembly includes a first oil scraper plate 13 and a second oil scraper plate 14, and the first oil scraper plate 13 and the second oil scraper plate 14 are located in the same horizontal plane, and the axes of the first oil scraper plate 13 and the second oil scraper plate 14 in the length direction coincide with each other. The adjacent ends of the first oil scraper plate 13 and the second oil scraper plate 14 are both drive-connected to the rotating shaft of the drive motor 12. The other end of the first oil scraper plate 13 is provided with an upward bending portion, on which a rubber pad 15 is fixedly mounted, and the rubber pad 15 abuts against the inner wall of the oil tank 1. At the same time, in this embodiment, the oil tank 1 is made of a transparent material. When the drive motor 12 drives the oil scraper assembly to rotate, the rubber pad 15 on the first oil hanging plate will form a mark on the side wall of the oil tank 1, indicating that the oil scraper assembly is operating normally. Therefore, by setting in the above manner, the operator can clearly see whether the oil scraper assembly is operating normally.

[0037] It is understandable that arranging the magnetic switch 4 inside the guide rod 2 instead of at the bottom of the oil tank 1 can prevent the magnetic switch 4 or other types of proximity switches from affecting the operation of the oil scraper assembly.

[0038] Therefore, the technical solution of the present application has a magnetic switch 4 fixedly installed at the lower part of the guide rod 2, and a magnetic block 5 fixedly installed at the upper end of the oil pressure plate 3. The cooperation between the magnetic switch 4 and the magnetic block 5 realizes the automatic low liquid level alarm, and avoids the magnetic switch 4 or other types of proximity switches from affecting the operation of the oil scraper assembly.

[0039] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
