Description

Technical Field

[0001] The present application relates to the technical field of sliding bearing cooling, and in particular to a cooling structure for a vertical sliding bearing. Background Art

[0002] During the operation of vertical sliding bearings, a lot of heat will be generated due to the friction. This heat mainly comes from the relative movement between the bearing and the shaft. High temperature may cause thermal expansion of the bearing material, change the geometric dimensions and matching accuracy of the bearing, and thus affect the operating stability and accuracy of the bearing. Long-term high-temperature operation may also lead to fatigue and wear of the bearing material, shortening the service life of the bearing. Therefore, after a period of use, it is recommended to remove the bearing for inspection. Some bearings are removed when the temperature is high after operation. At this time, they need to be cooled before inspection. The existing cooling method mostly uses cooling equipment to directly cool the bearing. Since the cooling temperature is very low at the beginning, the bearing may cause invisible deformation of the material when the temperature drops suddenly, and even damage in serious cases, causing unnecessary losses. Utility Model Content

[0003] The purpose of the present application is to provide a cooling structure for vertical sliding bearings, which solves the problem that the existing cooling method proposed in the background technology mostly uses cooling equipment to directly cool the bearings. Since the cooling temperature is very low at the beginning, the bearings may be deformed invisible to the naked eye when the temperature drops suddenly, and even damaged in serious cases, causing unnecessary losses.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a cooling structure for a vertical sliding bearing, comprising a cooling groove, a water leakage plate, a lifting groove and a baffle, a secondary support plate is fixedly installed at the center of the inner bottom of the cooling groove, a primary support plate is fixedly installed at the top left edge of the secondary support plate, a limiting plate is fixedly connected between the front and rear inner walls of the cooling groove above the primary support plate and the right edge of the secondary support plate, a baffle is movably inserted through the top of the limiting plate, a silicone rubber pad is inlaid and connected below the left side wall of the baffle, and a roller is rotatably connected between the front and rear inner walls of the cooling groove above the primary support plate and the secondary plate, a water cooler is fixedly installed at the inner bottom of the cooling groove below the primary support plate and the secondary support plate, a cooling pipe is connected to the top of the water cooler, the middle section of the cooling pipe is located below the roller, and one end of the cooling pipe is connected to a cooling pump fixedly installed at the top of the water cooler, a water leakage plate is fixedly connected between the secondary support plate and the inner right side wall of the cooling groove, springs are fixedly installed on both sides of the top of the water leakage plate, and a buffer plate is fixedly connected to the top of the spring.

[0005] In this technical solution, the water in the water tank is first pumped along the pumping pipe to between the primary support plate and the corresponding baffle of the cooling trough, and the bearing is placed on the roller above the support plate. The water will begin to cool the bearing. The bearing can be cooled step by step through the roller, baffle and cooling pipe. The water cooler below pumps cold water into the cooling pipe through the cooling pump to absorb heat and cool the water in the space above the primary support plate, thereby absorbing heat and cooling the bearing. After the heat absorption and cooling reaches a certain level, the baffle is lifted up, and the bearing will slide onto the roller above the secondary support plate. The cooling effect of the water cooler under the secondary support plate is better than that of the primary support plate. The water cooler under the plate is stronger, and continues to absorb heat and cool the bearing, thereby gradually lowering the temperature for cooling, avoiding the possible negative impact of a sudden drop in temperature on the bearing, ensuring the cooling efficiency while taking into account the protection effect on the bearing. At the same time, the baffle, silicone rubber pad, spring and buffer plate can be used to protect the bearing from collision. When the bearing slides on the drum, it will hit the silicone rubber pad on the baffle. After the baffle on the right side of the secondary support plate is lifted, the bearing will fall on the buffer plate. The impact force is reduced under the buffering of the spring, thereby avoiding the damage that may be caused by the impact of the bearing during movement and improving the protection effect on the bearing.

[0006] As an optional solution of the technical solution of the present application, two lifting grooves are vertically fixedly installed on the rear surface of the cooling groove, the inner side of the lifting groove is vertically rotatably connected with a threaded rod, the surface of the threaded rod is threadedly connected with a threaded block, the top surface of the threaded block located on the outer side of the lifting groove is fixedly connected with a lifting rod, and the other end of the lifting rod is fixedly connected to the upper side wall of the baffle.

[0007] As an optional solution of the technical solution of the present application, a motor is fixedly installed at the top of the lifting slot, and the output end of the transmission shaft of the motor is fixedly connected to the top of the threaded rod below.

[0008] As an optional solution of the technical solution of the present application, a water tank is movably placed on the left side of the cooling trough, the bottom end of the water pump is movably connected and communicated with the water pump inside the water tank, and the top end of the water pump passes through the top of the left side wall of the cooling trough and is located on the inner side of the cooling trough.

[0009] As an optional solution of the technical solution of the present application, a drain outlet is provided on the right side wall of the cooling trough below the water leakage plate, and a side door is hingedly connected to the edge of the notch provided on the right side wall of the cooling trough above the water leakage plate.

[0010] As an optional solution of the technical solution of the present application, the rollers above the primary support plate and the secondary support plate are inclined to the lower right.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present application can cool down the bearing step by step through the roller, baffle and cooling pipe. The water cooler below pumps cold water into the cooling pipe through the cooling pump to absorb heat and cool the water in the space above the primary support plate, thereby absorbing heat and cooling the bearing. After the heat absorption and cooling reaches a certain level, the baffle is lifted up and the bearing will slide onto the roller above the secondary support plate. The cooling effect of the water cooler below the secondary support plate is stronger than that of the water cooler below the primary support plate, and the bearing continues to absorb heat and cool, thereby gradually lowering the temperature for cooling, avoiding the possible negative impact of a sudden drop in temperature on the bearing, ensuring the cooling efficiency while taking into account the protection effect of the bearing.

[0013] 2. The present application can provide anti-collision protection for the bearing through the baffle, silicone rubber pad, spring and buffer plate. When the bearing slides on the drum, it will hit the silicone rubber pad on the baffle. After the baffle on the right side of the secondary support plate is lifted, the bearing will fall on the buffer plate. The impact force is reduced under the buffering of the spring, thereby avoiding damage to the bearing caused by collision during movement and improving the protection effect of the bearing.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0020] like Figure 1 and Figure 2As shown, a cooling structure for a vertical sliding bearing includes a cooling trough 1, a water leakage plate 4, a lifting trough 12 and a baffle 9. A drain port 19 is provided on the right side wall of the cooling trough 1 below the water leakage plate 4. A side door 18 is hingedly connected to the edge of the notch provided on the right side wall of the cooling trough 1 above the water leakage plate 4. The cooled bearing can be taken out after the side door 18 is opened.

[0021] like Figure 2 As shown, a secondary support plate 3 is fixedly installed at the center of the inner bottom of the cooling groove 1, a primary support plate 2 is fixedly installed at the left edge of the top of the secondary support plate 3, a limiting plate 8 is fixedly connected between the front and rear inner walls of the cooling groove 1 above the right edge of the primary support plate 2 and the secondary support plate 3, a baffle 9 is movably inserted through the top of the limiting plate 8, and the bottom of the baffle 9 is respectively fitted with the primary support plate 2 and the secondary support plate 3 to avoid water leakage, and a silicone rubber pad 7 is inlaid and connected at the bottom of the left side wall of the baffle 9. The silicone rubber pad 7 is a high-temperature resistant soft material and can buffer and block the bearing.

[0022] like Figure 2 As shown, a roller 101 is rotatably connected between the front and rear inner walls of the cooling groove 1 above the primary support plate 2 and the secondary support plate, and the roller 101 above the primary support plate 2 and the secondary support plate 3 is tilted to the lower right to facilitate the sliding of the bearing.

[0023] like Figure 2 As shown, water coolers 15 are fixedly installed at the bottom of the cooling groove 1 below the primary support plate 2 and the secondary support plate 3, and the top of the water cooler 15 is connected with a cooling pipe 17. The middle section of the cooling pipe 17 is located below the drum 101, and one end of the cooling pipe 17 is connected with a cooling pump 16 fixedly installed on the top of the water cooler 15. The cooling pump 16 can pump water in the cooling pipe 17 upward, and the cooling effect of the left and right water coolers 15 gradually increases, so that the bearing is cooled step by step. A water leakage plate 4 is fixedly connected between the secondary support plate 3 and the inner right side wall of the cooling groove 1, and springs 5 ​​are fixedly installed on both sides of the top of the water leakage plate 4. A buffer plate 6 is fixedly connected to the top of the spring 5. The buffer plate 6 buffers the sliding bearing under the elastic force of the spring 5 to prevent it from being damaged.

[0024] like Figure 3 As shown, two lifting grooves 12 are vertically fixedly installed on the rear side surface of the cooling groove 1, and the inner side of the lifting groove 12 is vertically rotatably connected with a threaded rod 13, and the surface of the threaded rod 13 is threadedly connected with a threaded block 11, and the top surface of the threaded block 11 located on the outer side of the lifting groove 12 is fixedly connected with a lifting rod 10, and the other end of the lifting rod 10 is fixedly connected to the upper side wall of the baffle 9. After the motor 14 is started, it drives the threaded rod 13 to rotate, so that the threaded block 11 rises with the lifting rod 10, thereby lifting the baffle 9.

[0025] like Figure 2 and Figure 3 As shown, a motor 14 is fixedly installed on the top of the lifting groove 12, and a water tank 20 is movably placed on the left side of the cooling groove 1 of the transmission shaft of the motor 14. The bottom end of the water pump 21 is movably connected and communicated with the water pump inside the water tank 20, and the top end of the water pump 21 passes through the upper left side wall of the cooling groove 1 and is located on the inner side of the cooling groove 1.

[0026] In actual use, the water in the water tank 20 is first pumped along the pumping pipe 21 to between the primary support plate 2 and the corresponding baffle plate 9 of the cooling tank 1, and the bearing is placed on the roller 101 above the support plate. The water will begin to cool the bearing, and the water cooler 15 below pumps cold water into the cooling pipe 17 through the cooling pump 16 to absorb heat and cool the water in the space above the primary support plate 2, thereby absorbing heat and cooling the bearing. After the heat absorption and cooling reaches a certain level, the baffle plate 9 is lifted up, and the bearing will slide onto the roller 101 above the secondary support plate 3. The cooling effect of the water cooler 15 below the secondary support plate 3 is stronger than that of the water cooler 15 below the primary support plate 2. The bearing is cooled by absorbing heat, so that the temperature is gradually reduced for cooling, avoiding the possible negative impact of a sudden drop in temperature on the bearing, ensuring the cooling efficiency while taking into account the protection effect of the bearing. When the bearing slides on the roller 101, it will hit the silicone rubber pad 7 on the baffle 9. After the baffle 9 on the right side of the secondary support plate 3 is lifted, the bearing will fall on the buffer plate 6. The impact force is reduced under the buffering of the spring 5, thereby avoiding possible damage to the bearing caused by the impact during the movement, and improving the protection effect of the bearing. When the bearing falls on the buffer plate 6, the cooling water that follows the slide passes through the leaking plate 4 and leaves the drain port 19. At this time, open the side door 18 to take out the bearing.

[0027] It should be noted that the water cooler 15 uses water as a cooling medium, and through the flow of water in the pipeline, heat is exchanged with the medium that needs to be cooled, thereby achieving the purpose of cooling and absorbing heat. It is a well-known device that can be directly purchased on the market. It is only used here, and no structural and functional improvements are made to it, so it will not be described in detail.
