Description

Technical Field

[0001] This utility model relates to the field of gear jet lubrication technology, and more specifically, to an open gear jet lubrication device. Background Technology

[0002] As a core transmission component of heavy equipment such as mining machinery, port equipment, and ship lifts, open gears are subjected to harsh working conditions of low speed, heavy load, and high levels of dust and impurities for extended periods. Their lubrication performance directly determines the operational stability and service life of the equipment. Open gear oil is suitable for the lubrication systems of open and semi-closed gearboxes as well as low-speed, heavy-load gear devices. It is widely used in operating machinery in industries such as cement, metallurgy, mining, and power, especially in some extra-large rotating equipment such as ball mills, dryers, and rotary kilns. Most existing open gear lubrication devices are fixed spray systems, where the nozzles are fixed to the equipment with rigid supports. When adjustments are needed, manual operation is required after the machine is stopped. This cannot adapt to the dynamic changes in gear operating conditions during production, significantly reducing the continuity of equipment operation. Furthermore, traditional devices rely on manual periodic inspections of the nozzle spray status, which is not only time-consuming and labor-intensive, but also makes it difficult to detect hidden faults such as pipe blockage and nozzle wear in a timely manner, thus affecting the lubrication effect. Therefore, an open gear spray lubrication device is proposed. Utility Model Content

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example 1 As attached Figure 1-4 An open gear jet lubrication device is shown, including a base plate 1 and a liquid pump 2, a high-pressure air pump 3, and a storage tank 4 fixed on the top of the base plate 1. The liquid pump 2 can be used as the power source for transporting lubricating fluid, and the high-pressure air pump 3 provides auxiliary power for the jetting of lubricating fluid. The output end of the liquid pump 2 is connected to a second distributor 6 through a pipe, and the output end of the high-pressure air pump 3 is connected to a first distributor 5 through a pipe. The first distributor 5 can divide and regulate the pressure of the compressed air output by the high-pressure air pump, and can evenly distribute the compressed air to the air inlet of each nozzle 8 according to the number of nozzles 8 and the working requirements. The outlet of the second distributor 6 is connected to the nozzle 8 through a pipe. A first support plate 7 is provided at the bottom of the first distributor 5 and the second distributor 6. The input end of the liquid pump 2 is connected to the inner cavity of the storage tank 4. The liquid pump 2 and the high-pressure air pump 3 are both located on one side of the storage tank 4. The cross-sectional shape of the first support plate 7 is set as "T". Mounting holes are opened on both sides of the bottom plate of the first support plate 7, the surface of the bottom plate 1, and the surface of the mounting plate 15. The air outlet of the first distributor 5 is connected to the air inlet of the nozzle 8 through a pipe and the solenoid valve 12. The outlet of the second distributor 6 is connected to the liquid inlet of the nozzle 8 through a pipe and the liquid electromagnetic flow meter 11. In use, the high-pressure air pump 3 atomizes the lubricant in the nozzle 8 and accelerates its spraying by compressing air pressure, so that the lubricant can be more evenly attached to the tooth surface and meshing gap of the open gear. The liquid pump 2 draws out the lubricant from the storage tank 4 and delivers it to the second distributor 6, and then delivers it evenly to multiple nozzles 8 and sprays it out. The first support plate 7 can support the first distributor 5 and the second distributor 6, making it convenient to install and fix the first distributor 5 and the second distributor 6.

[0019] A gas valve 9 is installed at the output end pipe of the high-pressure air pump 3, a liquid valve 10 is installed at the output end pipe of the liquid pump 2, an electromagnetic air valve 12 and a liquid electromagnetic flow meter 11 are respectively installed at the air inlet and liquid inlet of the nozzle 8, and a liquid level sensor 19 is embedded in the top of the storage tank 4. In use, the air valve 9 and liquid valve 10 can serve as the main control switch for the air and liquid circuits. During equipment maintenance or long-term shutdown, the fluid supply can be manually cut off, providing a safe operating environment for the staff. The electromagnetic air valve 12 can be set up to achieve automatic control of opening and closing. The liquid electromagnetic flow meter 11 can detect whether liquid is passing through, thereby determining whether there is blockage or damage. The liquid level sensor 19 can conveniently detect the liquid volume inside the storage tank 4, facilitating timely replenishment.

[0020] Example 2 Based on Embodiment 1, this embodiment also provides an open gear jet lubrication device, as shown in the attached figure. Figure 3 , 4 As shown, an adjustment mechanism is provided on one side of the nozzle 8. The adjustment mechanism includes a second support plate 13 fixed on one side of the nozzle 8. A connecting toothed column 14 is fixedly connected to one end of the second support plate 13. An installation plate 15 is provided on one side of the nozzle 8. A support base 16 is fixedly connected to the top of the installation plate 15. An electric push rod 17 is fixedly connected to one side of the installation plate 15. A toothed plate 18 is fixedly connected to the output end of the electric push rod 17. The cross-sectional shape of the second support plate 13 is set to "L" shape. The connecting tooth column 14 is rotatably connected to the support base 16. The tooth plate 18 is located on the side of the connecting tooth column 14 close to the mounting plate 15. The tooth plate 18 and the connecting tooth column 14 mesh with each other. A baffle is fixedly connected to the top of the tooth plate 18. The baffle is located on the top of the mounting plate 15. In use, the electric push rod 17 is activated to control the movement of the toothed plate 18, which can bring the connecting toothed column 14 to the second support plate 13 to rotate the nozzle 8 and adjust the orientation angle of the nozzle 8 to adapt to the lubrication requirements of open gears of different specifications. The mounting plate 15 can be used to conveniently install, fix and support the position of the nozzle 8.

[0021] It should be noted that both the second distributor 6 and the first distributor 5 have a separation chamber in their inner cavity. Each distribution chamber has an independent nozzle 8 connected to its corresponding pipe. The specific structure of the second distributor 6 is existing technology and can be set according to actual needs, so it will not be elaborated on further. Furthermore, a controller is installed on the top of the base plate 1. The controller is electrically connected to the liquid pump 2, the high-pressure air pump 3, the electromagnetic air valve 12, the electric push rod 17, the liquid electromagnetic flow meter 11, and the liquid level sensor 19. The controller has a display screen, operation buttons, and other structures, which can be set according to actual needs. No further explanation is needed. Meanwhile, the liquid level sensor 19 described in this application document is model number BL-YW-CL-31.

[0022] The working principle of this utility model is as follows: When in use, the mounting plate 15 is fixed to one side of the gear with bolts so that the nozzle 8 corresponds to the gear teeth. During installation, it is necessary to determine whether the rotation angle of the nozzle 8 is the same as the rotation direction of the gear. When the open gear starts running, the controller starts the liquid pump 2 and the high-pressure air pump 3 to draw out the liquid inside the storage tank 4 and input it into the corresponding second distributor 6 and first distributor 5 for diversion. The liquid is then fed into the nozzle 8 in sequence, where it is pressurized and sprayed out, thus adhering to the gear tooth surface and meshing gap to achieve a lubricating effect. During the lubrication process, the nozzle 8 can be rotated sequentially by activating the electric push rod 17, and the spray angle of the nozzle 8 can be adjusted to ensure that the lubricant always accurately covers the lubrication area. During operation, the level sensor 19 monitors the level of lubricating fluid in the storage tank 4 in real time, and the liquid electromagnetic flow meter 11 detects whether the flow rate is abnormal, thereby determining whether the nozzle 8 is malfunctioning. When an malfunction occurs, the controller sends a stop signal to shut down the high-pressure air pump 3, the liquid pump 2, the air valve 9, the liquid valve 10, and the solenoid air valve 12, facilitating quick stop and maintenance.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
