Description

Technical Field

[0001] This utility model relates to the field of lubrication technology, specifically to a centralized lubrication device with an automatic alarm function. Background Technology

[0002] The principle of a centralized lubrication device is to deliver lubricating oil or grease to a distributor through a lubricating oil supply source, and then the distributor distributes the lubricating medium to the lubrication points of equipment such as motors, guide rails or lead screws.

[0003] This centralized lubrication system is mainly composed of a lubrication pump, distributor, pipelines and connectors, and a monitoring and control system. The monitoring and control system can monitor the operating status and lubrication conditions of the lubrication system in real time, including the monitoring and control of parameters such as oil pressure, oil level, and flow rate. When the lubrication system malfunctions, it can automatically issue an alarm to remind maintenance personnel to repair it. This type of centralized lubrication system that can automatically issue an alarm can be called a centralized lubrication system with automatic alarm function.

[0004] However, when this centralized lubrication device malfunctions and issues an alarm, it cannot continue to operate while maintenance personnel are repairing it. When the centralized lubrication device stops due to maintenance, the motors, guide rails, or lead screws that are lubricated by this device may malfunction due to the interruption of the supply of lubricating oil or grease. Therefore, it does not meet the existing needs. To address this, we propose a centralized lubrication device with an automatic alarm function. Utility Model Content

[0005] The purpose of this utility model is to provide a centralized lubrication device with an automatic alarm function, so as to solve the problems mentioned in the background art, such as when the centralized lubrication device malfunctions and issues an alarm, the centralized lubrication device cannot continue to work when maintenance personnel perform maintenance, and when the centralized lubrication device stops due to maintenance, the motor, guide rail or lead screw and other equipment lubricated by the device may malfunction due to the interruption of the supply of lubricating oil or grease.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centralized lubrication device with automatic alarm function, comprising a first centralized lubrication pump, a first lubrication pump outlet installed on one side of the outer surface of the first centralized lubrication pump, a second centralized lubrication pump provided behind the first lubrication pump outlet, a second lubrication pump outlet installed on one side of the outer surface of the second centralized lubrication pump, a slide rail provided below the second lubrication pump outlet, a slide table slidably installed on one side of the upper end face of the slide rail, a stepper motor fixedly installed on one side inside the slide table, the output shaft of the stepper motor connected to a transmission shaft via a coupling, a first gear fixedly sleeved on the lower side of the outer surface of the transmission shaft, the first gear meshing with a second gear, a roller bearing ring fixedly installed inside the second gear and connected to the slide table via a roller bearing, an internal threaded sleeve connected to the slide table via a threaded structure above the roller bearing ring, and a movable insert rod fixedly connected to both sides of the upper end face of the roller bearing ring and inserted into the internal threaded sleeve, and a lubricating oil connector fixedly installed on the inner side of the internal threaded sleeve;

[0007] An internal thread fixing groove is provided at the middle position of the lower end face of the first lubrication pump oil outlet and the second lubrication pump oil outlet. An oil outlet connecting groove is provided at the middle position of the upper inner wall of the internal thread fixing groove, and the two oil outlet connecting grooves are respectively connected to the interior of the first centralized lubrication pump and the second centralized lubrication pump.

[0008] Preferably, the position of the internal thread fixing groove located on the lower end face of the oil outlet of the second lubrication pump corresponds to the position of the internal thread sleeve, and the external thread of the internal thread sleeve matches the internal thread of the internal thread fixing groove.

[0009] Preferably, an oil supply pipe is connected to the middle position of the lower end face of the lubricating oil connector, and a distributor is connected to the front end face of the oil supply pipe.

[0010] Preferably, a pressure sensor is fixedly installed on the lower end face of the lubricating oil connector on one side of the oil supply pipe, and the monitoring probe of the pressure sensor is inserted into the interior of the lubricating oil connector.

[0011] Preferably, a PLC programmable logic controller is fixedly installed on one side of the outer surface of the slide rail, and the first centralized lubrication pump, the second centralized lubrication pump, the slide table, the stepper motor and the pressure sensor are all electrically connected to the PLC programmable logic controller.

[0013] Preferably, a protective cover plate is provided behind the stepper motor on the outer surface of the slide, and the slide and the protective cover plate are fixed together by screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, when the device is needed, starts a stepper motor to insert the lubricating oil connector into the oil outlet connection groove inside the oil outlet of the second lubricating pump, thereby connecting the second centralized lubricating pump to the lubricating oil connector. The second centralized lubricating pump then delivers lubricating oil or grease into the lubricating oil connector, ensuring the normal operation of the distributor connected to the lubricating oil connector. If the pressure sensor connected to the lower end face of the lubricating oil connector detects abnormalities in oil pressure, oil level, or flow, the slide table and stepper motor automatically disconnect the connection between the second centralized lubricating pump and the lubricating oil connector and connect the lubricating oil connector to the first centralized lubricating pump. With this technical solution, when one of the centralized lubricating pumps fails, another centralized lubricating pump can be automatically replaced to deliver lubricating oil or grease, thus preventing the device from becoming unusable due to a faulty centralized lubricating pump.

[0016] 2. This utility model allows for the direct replacement of centralized lubrication pumps that provide lubricating oil or grease via a slide table and a stepper motor. The lubricating oil connector can only be connected to one centralized lubrication pump at a time, and there is no connecting mechanism between two centralized lubrication pumps. This technical solution can prevent a malfunctioning centralized lubrication pump from affecting another centralized lubrication pump, thereby ensuring the stability of the replaced centralized lubrication pump during operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The first centralized lubrication pump 1 (model YL-ELP10-G-2), stepper motor 7 (model DM542), and first gear 9 (model M08) mentioned in this utility model can be obtained from the market or through private customization.

[0024] Please see Figures 1 to 4 This utility model provides an embodiment of a centralized lubrication device with an automatic alarm function, comprising a first centralized lubrication pump 1, an oil outlet 3 of the first lubrication pump 1 installed on one side of its outer surface, a second centralized lubrication pump 2 located behind the oil outlet 3, an oil outlet 4 of the second lubrication pump 2 installed on one side of its outer surface, a slide rail 5 located below the oil outlet 4, a slide table 6 slidably mounted on one side of the upper surface of the slide rail 5, and a stepper motor 7 fixedly mounted on one side inside the slide table 6, the stepper motor 7 outputting... The shaft is connected to the transmission shaft 8 via a coupling. A first gear 9 is fixedly sleeved on the lower side of the outer surface of the transmission shaft 8. The first gear 9 meshes with a second gear 10. A roller bearing ring 11 is fixedly installed inside the second gear 10 and is connected to the slide table 6 via a roller bearing. An internal threaded sleeve 13 is provided above the roller bearing ring 11 and is connected to the slide table 6 via a threaded structure. A plug rod 12 that can be inserted into the internal threaded sleeve 13 is fixedly connected to both sides of the upper end face of the roller bearing ring 11. A lubricating oil connector 14 is fixedly installed on the inner side of the internal threaded sleeve 13.

[0025] An internal thread fixing groove 15 is provided at the middle position of the lower end face of the first lubrication pump oil outlet 3 and the second lubrication pump oil outlet 4. An oil outlet connecting groove 16 is provided at the middle position of the upper inner wall of the internal thread fixing groove 15, and the two oil outlet connecting grooves 16 are respectively connected to the interior of the first centralized lubrication pump 1 and the second centralized lubrication pump 2.

[0026] An oil supply pipe 18 is connected to the middle position of the lower end face of the lubricating oil connector 14, and a distributor 19 is connected to the front end face of the oil supply pipe 18. A pressure sensor 17 is fixedly installed on one side of the oil supply pipe 18 and fixedly mounted on the lower end face of the lubricating oil connector 14. The monitoring probe of the pressure sensor 17 is inserted into the interior of the lubricating oil connector 14. A PLC programmable logic controller is fixedly installed on one side of the outer surface of the slide rail 5, and the first centralized lubrication pump 1, the second centralized lubrication pump 2, the slide table 6, the stepper motor 7 and the pressure sensor 17 are all electrically connected to the PLC programmable logic controller. The various mechanisms on the equipment can be controlled through the electrical connection between the PLC programmable logic controllers.

[0027] The position of the internal thread fixing groove 15 located on the lower end face of the oil outlet 4 of the second lubrication pump corresponds to the position of the internal thread sleeve 13, and the external thread of the internal thread sleeve 13 matches the internal thread of the internal thread fixing groove 15. When the equipment needs to be used, the stepper motor 7 is started. The stepper motor 7 can drive the transmission shaft 8 connected to it and the first gear 9 fixedly sleeved on the outer surface of the transmission shaft 8 to rotate. The rotating first gear 9 can drive the second gear 10 meshing with it and the roller bearing ring 11 fixed inside the second gear 10 to rotate together. When the roller bearing ring 11 rotates, the two insert rods 12 fixed on the upper end face of the roller bearing ring 11 will revolve accordingly. As the insert rods 12 revolve, the internal thread sleeve 13 inserted by the two insert rods 12 will rotate synchronously. The threaded structure between the internal threaded sleeve 13 and the slide table 6 allows the rotating internal threaded sleeve 13 to move up and down. When the internal threaded sleeve 13 moves upward, as it rises, the internal threaded sleeve 13 and the lubricating oil connector 14 fixed to the inner wall of the internal threaded sleeve 13 will respectively enter the internal thread fixing groove 15 on the lower end face of the oil outlet 4 of the second lubricating pump fixed to the outer surface of the second centralized lubricating pump 2 and the oil outlet connecting groove 16 located on the upper inner wall of the internal thread fixing groove 15. This connects the lubricating oil connector 14 to the second centralized lubricating pump 2. Then, the second centralized lubricating pump 2 can deliver lubricating oil or grease into the lubricating oil connector 14 to ensure that the distributor 19 connected to the lubricating oil connector 14 through the oil supply pipe 18 can operate normally.

[0028] When the pressure sensor 17 connected to the lower end face of the lubricating oil connector 14 detects an abnormality in oil pressure, oil level, or flow rate, the stepper motor 7 is activated to rotate the internal threaded sleeve 13 connected to it in reverse, thereby disconnecting the connection between the lubricating oil connector 14 and the second centralized lubrication pump 2. Then, the slide table 6 moves the internal threaded sleeve 13 and the lubricating oil connector 14 to below the first lubricating pump outlet 3 installed on the outer surface of the first centralized lubrication pump 1. The stepper motor 7 then installs the internal threaded sleeve 13 and the lubricating oil connector 14 respectively onto the first lubricating pump outlet 3 fixed on the outer surface of the first centralized lubrication pump 1. The internal thread fixing groove 15 on the lower end face of the port 3 and the oil outlet connecting groove 16 located on the upper inner wall of the internal thread fixing groove 15 are used to connect the lubricating oil connector 14 to the first centralized lubrication pump 1. Then, the first centralized lubrication pump 1 can deliver lubricating oil or grease to the distributor 19 to ensure the normal operation of the distributor 19. With the above technical solution, when one of the centralized lubrication pumps in use fails, another centralized lubrication pump can be automatically replaced to deliver lubricating oil or grease, thereby preventing the equipment from being unusable when the centralized lubrication pump fails.

[0029] The above mechanism can directly replace the centralized lubrication pump that provides lubricating oil or grease through the slide table 6 and the stepper motor 7. The lubricating oil connector 14 can only be connected to one centralized lubrication pump at a time. There is no connection mechanism between the two centralized lubrication pumps. The above technical solution can prevent the failure of the centralized lubrication pump from affecting the other centralized lubrication pump, thereby ensuring the stability of the replaced centralized lubrication pump during operation.

[0030] If the pressure sensor 17 detects an abnormality in oil pressure, oil level, or flow rate, the PLC programmable logic controller electrically connected to the pressure sensor 17 will automatically issue an alarm to remind maintenance personnel to come and perform maintenance work.

[0031] The faces of the first centralized lubrication pump 1 and the second centralized lubrication pump 2 facing the slide rail 5 are both fixed to the slide rail 5. A bolt fixing plate for bolt fixing is fixedly installed on the front face of the bottom end of the first centralized lubrication pump 1 and the rear face of the rear end of the second centralized lubrication pump 2. The whole equipment can be fixed by the two bolt fixing plates.

[0032] A protective cover plate is provided behind the stepper motor 7 on the outer surface of the slide table 6, and the slide table 6 and the protective cover plate are fixed together by screws. The protective cover plate can protect the internal structure of the slide table 6, and when the internal structure of the slide table 6 fails, the protective cover plate can be removed to repair the internal structure of the slide table 6.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
