Description

Technical Field

[0001] This utility model relates to a kiln car bearing lubrication device, specifically, to an automatic lubrication device for kiln car bearings used in the high-temperature firing of special ceramic balls. Background Technology

[0002] Kiln cars are one of the most important product loading tools in ceramic production. During the firing process, the kiln car follows the product from the kiln head to the kiln tail, experiencing the entire firing process of sanitary ware. When the kiln car is running inside the kiln, some of the high temperature inside the kiln is conducted to the bottom of the kiln car through the insulation cotton and the kiln car's curved seal, causing the temperature of the kiln car wheels to rise, sometimes reaching over 300 degrees Celsius. The kiln car wheel bearings will experience many problems due to long-term operation at high temperatures. Nowadays, most firing processes regularly add lubricating oil to the kiln car bearings to ensure that the kiln car can operate flexibly both inside and outside the kiln. In order to pursue a greater effective loading height, reduce kiln construction costs, and reduce the difficulty of kiln loading operations, kiln companies and production units will appropriately lower the distance between the kiln car's iron parts and the ground. This also makes it more difficult for operators to lubricate the bearings. Because the distance under the car is too small, operators need to spend more time and effort when adding lubricating oil.

[0003] Regarding the aforementioned problems, and the technical difficulties in adding lubricating oil to existing kiln cars, extensive research revealed an automatic lubrication device for kiln cars with patent publication number CN209638744U. This device includes a kiln car, a kiln car track, an oil nozzle, an air compressor, an oil storage tank containing lubricating oil, and a proximity switch. This invention replaces manual labor with equipment, using compressed air or an air compressor to pressurize the oil storage tank. When the kiln car wheels reach a designated position, the lubricating oil in the storage tank is pressurized by the air compressor and sprayed accurately into the bearing gaps through the oil delivery system to clean and lubricate the bearings. However, the high temperature in the kiln car working area means that directly spraying the lubricating oil into the air causes it to evaporate quickly, resulting in waste. Furthermore, the poor air circulation in the workshop often leads to lubricating oil evaporating into the atmosphere, which can seriously affect the health of workers.

[0004] This invention can automatically add oil, automatically alarm when oil is low, reduce the temperature of lubricating oil, and prevent damage to the device due to excessive pressure in the oil inlet pipe. Summary of the Invention

Beneficial effects

[0017] 1. Automatic oil filling is achieved by setting up an oil pressure chamber; when the telescopic cylinder is activated, it moves the oil pressure plate upward through the oil pressure rod. At this time, the pressure in the oil pressure chamber decreases, and the first spring can push open the first pressure plate, allowing the lubricating oil in the oil reservoir to enter the oil pressure chamber. Then, the telescopic cylinder moves the oil pressure plate downward through the oil pressure rod, and the pressure in the oil pressure chamber increases, causing the first pressure plate to be pressed into the oil inlet groove. At this time, the lubricating oil cannot enter the oil reservoir. At the same time, the second pressure plate will open due to the increase in oil pressure, allowing the lubricating oil to be supplied into the oil inlet pipe and then into the bearing to complete the automatic oil filling.

[0018] 2. Equipped with a float, limit switch, and buzzer, it achieves an automatic oil shortage alarm. During operation, the float descends as the lubricating oil level drops. When the device is low on lubricating oil, the float reaches its lowest point, and the counterweight at the top of the device presses against the limit switch. The limit switch then sends a signal to the control board, causing the buzzer to sound an alarm and simultaneously stopping the oil pumping operation of the telescopic cylinder.

[0019] 3. By setting up a heat dissipation device, the temperature of the lubricating oil is reduced. The cooling water first absorbs the heat of the lubricating oil in the heat absorption pipe, then enters the heat dissipation fins in the cooling rack from the water outlet pipe to dissipate heat. Then it flows into the water inlet pipe and is pumped into the heat absorption pipe by the water pump to enter the next heat absorption cycle. The fan and water pump can be turned on and off according to the lubricating oil temperature sensed by the temperature sensor, thereby ensuring that the lubricating oil is kept at a low temperature.

[0020] 4. By incorporating a pressure limiting device, the device is protected from damage due to excessive pressure in the oil inlet pipe. During normal use, the third spring applies pressure to the third pressure plate, pressing it firmly against the fixed ring, preventing lubricating oil from passing through. When the oil pressure is too high, the lubricating oil pushes open the third pressure plate and enters the return oil pipe from the bottom of the pressure limiting housing, thus reducing the pressure in the oil inlet pipe and preventing damage. To adjust the pressure limited by the pressure limiting device, rotate the handle, causing the threaded rod to rotate. Under the limit of the threaded sleeve, the threaded rod moves the base plate up and down, thereby adjusting the pressure applied to the third pressure plate by the third spring and changing the pressure limited by the pressure limiting device.

[0021] 5. In summary, the automatic lubrication device for the kiln car bearing of this type of high-temperature fired special ceramic ball, by setting up an oil pressure chamber, float ball, limiter, buzzer, heat dissipation device and pressure limiting device, can play the roles of automatic lubrication, automatic alarm for insufficient oil, reducing lubricating oil temperature and preventing damage to the device due to excessive pressure in the oil inlet pipe.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0030] Please see Figure 1-6 In this embodiment of the invention, an automatic oiling device for a kiln car bearing used in the high-temperature firing of special ceramic balls includes: a kiln car bearing 1; an oil inlet pipe 6 and an oil return pipe 7 are connected to the outside of the kiln car bearing 1; an oil pressure chamber 2 is fixedly connected to the other end of the oil inlet pipe 6; an oil storage chamber 3 is installed at the other end of the oil return pipe 7; a heat dissipation device 4 is installed at the right end of the oil storage chamber 3; and a control board 8 is installed at the left end of the oil pressure chamber 2.

[0031] A cylinder is installed at the top of the oil pressure chamber 2. An oil pressure rod 202 is fixedly connected to the output end of the telescopic cylinder 203.

The left end of the oil inlet groove is connected to the second pressure plate 207. The fitting allows the second pressure plate 207 to be embedded into the oil groove. Activating the telescopic cylinder 203 causes it to move the pressure plate 201 upwards via the pressure rod 202. At this time, the pressure in the oil chamber 2 decreases, and the first spring 206 pushes open the first pressure plate 205, allowing the lubricating oil in the oil reservoir 3 to enter the oil chamber 2. Then, the telescopic cylinder 203 moves the pressure plate 201 downwards via the pressure rod 202, causing the pressure in the oil chamber 2 to rise. This causes the first pressure plate 205 to be pressed into the oil groove, preventing lubricating oil from entering the oil reservoir 3. Simultaneously, the second pressure plate 207 opens due to the increased pressure in the oil chamber 2, allowing lubricating oil to be supplied into the oil inlet pipe 6 and then into the bearing to complete the automatic lubrication process.

[0032] In this embodiment of the utility model, a plurality of relays 9 are installed on the top of the control board 8. The relays 9 are electrically connected to the control board 8, so as to facilitate the control of the circuit by the control board 8.

[0033] In this embodiment of the utility model, an oil inlet 10 is installed at the upper left end of the oil storage chamber 3; a float 11 is installed at the right end of the oil inlet 10; the float 11 consists of a ball at the bottom, a central part, and a counterweight at the top; a limit switch 12 is installed at the right end of the float 11; the control board 8 is electrically connected to the limit switch 12; a buzzer 13 is installed at the right end of the limit switch 12; the control board 8 is electrically connected to the buzzer 13 to achieve the effect of automatic alarm when oil is low. When in use, the float 11 will descend as the lubricating oil level drops. When the device is low on lubricating oil, the float 11 is at the lowest end, and the counterweight at the top of the device will press against the limit switch 12. The limit switch 12 will send a signal to the control board 8, causing the buzzer 13 to sound an alarm and simultaneously stop the oil pumping operation of the telescopic cylinder 203.

[0034] In this embodiment of the utility model, an oil outlet pipe 104 is provided at the left end of the kiln car bearing 1 and an oil outlet pipe 104 is provided at the right end of the kiln car bearing 1.

An oil inlet pipe 6 and an oil return pipe 7 are connected to the oil change connector 103, so as to facilitate the oiling of the kiln car bearing 1. When in use, the oil change connector 103 is inserted into the oil change interface 102, thus completing the connection between the kiln car bearing 1 and the oil inlet pipe 6 and the oil return pipe 7, and lubricating oil can be injected.

[0035] In addition, the kiln car bearing 1 is a combination of an existing sealed bearing with an oil injection pipe 101, an oil outlet pipe 104 and an oil change interface 102. The sealing of the sealed bearing is an existing technology. The oil injection pipe 101 and the oil outlet pipe 104 should also be equipped with a check valve and other devices to prevent the lubricating oil from flowing out on its own after the lubricating oil is changed. This is also an existing technology.

[0036] In this embodiment of the utility model, the heat dissipation device 4 includes: an outlet pipe 401, a heat absorption pipe 402, an inlet pipe 403, heat dissipation fins 404, a cooling rack 405, and a water pump 406. A plurality of heat absorption pipes 402 are fixedly connected inside the oil storage chamber 3. An outlet pipe 401 is fixedly connected to the top end of each heat absorption pipe 402. A cooling rack 405 is fixedly connected to the other end of the outlet pipe 401. A plurality of heat dissipation fins 404 are disposed inside the cooling rack 405. An inlet pipe 406 is fixedly connected to the bottom end of the cooling rack 405. 3. A heat absorption pipe 402 is fixedly connected to the other end of the water inlet pipe 403. A water pump 406 is installed in the center of the water inlet pipe 403. The water pump 406 is electrically connected to the control board 8 to achieve the effect of reducing the temperature of the lubricating oil. When in use, the cooling water first absorbs the heat of the lubricating oil in the heat absorption pipe 402, and then enters the heat dissipation fins 404 in the cooling rack 405 from the water outlet pipe 401 to dissipate heat. Then it flows into the water inlet pipe 403 and is pumped into the heat absorption pipe 402 by the water pump 406 to enter the next heat absorption cycle.

[0037] In this embodiment of the utility model, a fan 407 is provided at the rear end of the heat dissipation fin 404. The fan 407 is electrically connected to the control board 8, so as to achieve the effect of further and correctly dissipating heat through the fan 407.

[0038] In this embodiment of the utility model, a temperature sensor 14 is installed at the bottom of the oil storage chamber 3. The temperature sensor 14 is electrically connected to the control board 8, so as to facilitate the opening and closing of the fan 407 and the water pump 406 according to the temperature sensor 14, and to accurately control the temperature of the lubricating oil.

[0039] In this embodiment of the present invention, a pressure limiting device 5 is provided between the oil inlet pipe 6 and the oil return pipe 7;

[0040] In this embodiment of the utility model, the pressure limiting device 5 includes a pressure limiting shell 501, a fixing ring 502, a third pressure plate 503, a third spring 504, and a base plate 505. One end of the oil inlet pipe 6 is connected to the upper end of the pressure limiting shell 501. A fixing ring 502 is fixedly connected to the center inside the pressure limiting shell 501. A third pressure plate 503 is installed at the bottom end of the fixing ring 502. A third spring 504 is fixedly connected to the bottom end of the third pressure plate 503. The base plate 505 is fixedly connected to the bottom end of the third spring 504. A return oil pipe 7 is connected to the lower end of the pressure limiting shell 501. This achieves the effect of preventing excessive pressure in the oil inlet pipe 6 when there is pipeline blockage, which could damage the device. During normal use, the third spring 504 applies pressure to the third pressure plate 503, pressing it tightly against the fixing ring 502, preventing lubricating oil from passing through the device. When the oil pressure is too high, the lubricating oil will push open the third pressure plate 503 and enter the return oil pipe 7 from the bottom end of the pressure limiting shell 501, thereby reducing the pressure in the oil inlet pipe 6 and preventing damage to the device.

[0041] In this embodiment of the utility model, a threaded rod 506 is rotatably connected to the bottom end of the base plate 505, and a handle 508 is connected to the other end of the threaded rod 506. A threaded sleeve 507 is installed in the center of the threaded rod 506, and a pressure limiting shell 501 is fixedly connected to the top end of the threaded sleeve 507, so as to achieve the effect of adjusting the pressure limited by the pressure limiting device 5. Rotating the handle 508 drives the threaded rod 506 to rotate. Under the limitation of the threaded sleeve 507, the threaded rod 506 drives the base plate 505 to move up and down, thereby adjusting the pressure applied to the third pressure plate 503 by the third spring 504 and changing the pressure limited by the pressure limiting device 5.

[0042] Working principle:

[0043] Inserting the oil change connector 103 into the oil change interface 102 completes the connection between the kiln car bearing 1 and the oil inlet pipe 6 and the oil return pipe 7. Then, the telescopic cylinder 203 is activated, causing it to move the pressure plate 201 upwards via the pressure rod 202. At this time, the pressure in the pressure chamber 2 decreases, and the first spring 206 can push open the first pressure plate 205, allowing the lubricating oil in the oil storage chamber 3 to enter the pressure chamber 2. Next, the telescopic cylinder 203 moves the pressure plate 201 downwards via the pressure rod 202, increasing the pressure in the pressure chamber 2. This causes the first pressure plate 205 to be pressed into the oil inlet groove, preventing lubricating oil from entering the oil storage chamber 3. Simultaneously, the second pressure plate 207 opens due to the increased pressure in the pressure chamber 2, allowing lubricating oil to be supplied into the oil inlet pipe 6 and then into the bearing to complete the automatic lubrication. When it is necessary to lower the lubricant temperature, the cooling water first absorbs the heat from the lubricating oil through the heat absorption pipe 402, and then dissipates heat from the cooling fins 404 inside the cooling rack 405 through the water outlet pipe 401. The lubricating oil then flows into the inlet pipe 403 and is pumped into the heat absorption pipe 402 by the water pump 406 to enter the next heat absorption cycle. The fan 407 and water pump 406 are turned on and off based on the temperature of the lubricating oil sensed by the temperature sensor 14, thus ensuring the lubricating oil is kept at a low temperature. During normal use, the third spring 504 applies pressure to the third pressure plate 503, pressing it tightly against the fixing ring 502, preventing the lubricating oil from passing through the device. When the oil pressure is too high, the lubricating oil will push open the third pressure plate 503 and enter the return oil pipe 7 from the bottom of the pressure limiting shell 501, thereby reducing the pressure in the oil inlet pipe 6 and preventing damage to the device. When it is necessary to adjust the pressure limited by the pressure limiting device 5, the handle 508 is turned, causing the threaded rod 506 to rotate. Under the limit of the threaded sleeve 507, the threaded rod 506 drives the base plate 505 to move up and down, thereby adjusting the pressure applied to the third pressure plate 503 by the third spring 504 and changing the pressure limited by the pressure limiting device 5.
