Description
Technical Field
[0001] The utility model belongs to the technical field of hot-installation operations of reducers and the like of cranes, and in particular relates to a multi-medium intelligent cooling device. Background Art
[0002] At present, the assembly of reducers in the industry is mainly divided into two methods: hot installation and cold installation. Our company's reducers are all assembled by hot installation. Hot installation refers to heating the workpiece to be assembled to make it expand and deform, inserting the output shaft of the reducer into the workpiece, and after the temperature of the workpiece drops, the reducer and the workpiece are tightly connected. The advantages of hot installation are fast assembly speed and tight connection, but during assembly, due to the high temperature of the workpiece, the high temperature is close to the oil seal of the reducer, which often causes the oil seal of the reducer to fail, resulting in oil leakage of the reducer, which brings great trouble to the assembly. In order to solve the above problems, circulating water cooling is often used to cool the workpiece. The circulating water temperature is not adjusted in time, resulting in an unobvious cooling effect. Summary of the invention
[0003] In view of the problems in the prior art of heat assembly of reducers, such as excessive workpiece temperature causing failure of reducer oil seal and oil leakage of reducer, the utility model provides a multi-medium intelligent cooling device for heat assembly of reducers, which changes the existing cooling operation mode, adopts a multi-medium hierarchical control system, accurately controls the workpiece temperature, and ensures assembly quality.
[0004] The purpose of the utility model is achieved in the following ways:
[0005] A multi-media intelligent cooling device, comprising a water storage support tray, a cooling device and an intelligent temperature control device, a water collection tank is arranged at the bottom of the water storage support tray, a grid plate is laid at the top of the water collection tank, the inner surface of the bottom of the water collection tank is inclined at a slope of 1:20, and the water collection tank is connected to the water storage tank through a pipeline;
[0006] The cooling device includes an air-cooled cooling gun, a water-cooled cooling gun and a magnetic seat. The cooling device is electromagnetically adsorbed on the reducer through the magnetic seat. The reducer is located above the water storage support tray. The air-cooled cooling gun and the water-cooled cooling gun are arranged above the magnetic seat through a bracket. The air-cooled cooling gun and the water-cooled cooling gun act on the workpiece assembled with the reducer. The air-cooled cooling gun is connected to the air source through a gas pipeline. The water-cooled cooling gun is connected to the water storage tank through a circulating water pump and a cooling water pipeline. A liquid nitrogen pipeline is also fixedly arranged on the bracket. The gas pipeline and the cooling water pipeline are spirally wound side by side on the liquid nitrogen pipeline.
[0007] The intelligent temperature control device includes an infrared temperature detector, a temperature display screen, an audible and visual alarm and a controller. The infrared temperature detector is electromagnetically adsorbed on the oil seal position on the surface of the reducer. The infrared temperature detector is connected to the controller. The controller is connected to the temperature display screen and the audible and visual alarm. The temperature display screen and the audible and visual alarm are arranged on the water storage support tray through supporting poles.
[0008] The grating laid on the top of the collection tank is galvanized steel grating.
[0009] Compared with the prior art, the utility model changes the existing cooling operation mode and uses liquid nitrogen to cool the cooling water or compressed air, so that the temperature of the water and gas sprayed out by the cooling device is lower, and the temperature adjustment of the circulating water and gas is more timely, so that the high-temperature workpiece can be quickly cooled to the required temperature, solving the problem of excessive temperature during the assembly of the reducer, resulting in oil seal failure, and can greatly reduce the cooling time and improve assembly efficiency. The gas pipeline and the cooling water pipeline are designed to be spirally intertwined on the liquid nitrogen pipeline, which increases the contact area between the liquid nitrogen pipeline and the water and gas pipelines, so that the liquid nitrogen can fully cool the water and gas in the cooling pipeline. The design of the cooling water recovery pipeline realizes the recycling and reuse of cooling water, saving resources while improving the cleanliness of the operating site.

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention, and are not used to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present invention.
[0018] like Figure 1-7 As shown, a multi-media intelligent cooling device includes a water storage support tray 1, a cooling device 2 and an intelligent temperature control device 3. A collecting water tank 11 is arranged at the lower part of the water storage support tray 1, a grid plate 12 is laid on the upper part of the collecting water tank 11, and the inner surface of the bottom of the collecting water tank 11 is inclined with a slope of 1:20. The collecting water tank 11 is connected to the water storage tank 13 through a pipeline. The cooling device 2 includes an air-cooled cooling gun 21, a water-cooled cooling gun 22 and a magnetic seat 23. The cooling device 2 is electromagnetically adsorbed on the reducer 4 through the magnetic seat 23. The reducer 4 is located above the water storage support tray 1. The air-cooled cooling gun 21 and the water-cooled cooling gun 22 are arranged above the magnetic seat 23 through a bracket 231. The air-cooled cooling gun 21 and the water-cooled cooling gun 22 act on the workpiece assembled with the reducer. The air-cooled cooling gun 21 is connected to the air source through a gas pipeline 25, and the water-cooled cooling gun 22 is connected to the water storage tank 13 through a circulating water pump 14 and a cooling water pipeline 26. A liquid nitrogen pipeline 24 is also fixedly arranged on the bracket 231, and the gas pipeline 25 and the cooling water pipeline 26 are spirally wound side by side on the liquid nitrogen pipeline 24. The intelligent temperature control device 3 includes an infrared temperature detector 31, a temperature display screen 32, an audible and visual alarm 33 and a controller 34. The infrared temperature detector 31 is electromagnetically adsorbed on the oil seal position on the surface of the reducer. The infrared temperature detector 31 is connected to the controller 34. The controller 34 is connected to the temperature display screen 32 and the audible and visual alarm 33. The temperature display screen 32 and the audible and visual alarm 33 are arranged on the water storage support tray 1 through the supporting pole 15.
[0019] A grating 12 is laid on the top of the water collecting tank 11, and the inner surface of the bottom of the water collecting tank 11 is inclined to facilitate the cooling water in the water collecting tank 11 to flow into the water storage tank 13, so as to facilitate the recycling and reuse of the cooling water. The cooling water is collected and recycled, which saves resources and improves the cleanliness of the operation site.
[0020] In addition, the size of the grid plate 12 is smaller than the upper surface of the water collection tank 11, and the water collection tank 11 reserves a certain width not to cover the grid plate 12 to prevent water leakage. The grid plate laid on the upper part of the water collection tank 11 is a galvanized steel grid plate, which has good corrosion resistance and good heat dissipation effect.
[0021] Furthermore, multiple water storage support trays 1 are connected in series or in parallel to accommodate simultaneous hot-installation of multiple reducers. The number of water storage support trays can also be increased or decreased and the spacing between the water storage support trays can be adjusted according to actual usage requirements.
[0022] The air-cooling cooling gun 21 performs air cooling on the workpiece. According to the test, the surface temperature of the workpiece can be reduced by about 20°C within 10 seconds. The water-cooling cooling gun 22 performs water flow cooling on the workpiece, which has a better cooling effect. The used cooling water flows into the water storage tank 13 through the grid plate 12, and finally flows into the water storage tank 13 to be circulated through the circulating water pump 14.
[0023] The gas pipeline 25 and the cooling water pipeline 26 are spirally intertwined and wound around the liquid nitrogen pipeline 24, which increases the contact area between the liquid nitrogen pipeline and the gas pipeline 25 and the cooling water pipeline 26, so that the liquid nitrogen in the liquid nitrogen pipeline 24 can fully and quickly cool the compressed air in the gas pipeline 25 and the cooling water in the cooling water pipeline 26, so that the temperature of the water sprayed by the water-cooled cooling gun 22 and the gas sprayed by the air-cooled cooling gun 21 is lower, and the high-temperature workpiece can be quickly cooled to the required temperature, which can greatly reduce the cooling time and improve the assembly efficiency.
[0024] The infrared temperature detector 31 monitors the temperature of the oil seal position in real time during the working process, with a detection accuracy of ±0.2°C, and transmits the detection data to the controller 34, and displays it in real time on the temperature display screen 32. When the reducer and the workpiece are assembled, the heating temperature of the workpiece is as high as 200°C, or even more than 200°C. Even if water cooling or air cooling is performed, the temperature of the oil seal position will not drop instantly. Therefore, the temperature of the oil seal position is a changing process. The infrared temperature detector 31 detects that the real-time temperature of the oil seal position is lower than 45°C, and the cooling device 2 does not work temporarily. When the real-time temperature exceeds 45°C and is lower than 85°C, the controller 34 starts the air-cooled cooling gun 21 to cool the workpiece; when the real-time temperature is higher than 85°C and lower than 100°C, the controller 34 starts the water-cooled cooling gun 22 to cool the workpiece and turns off the air-cooled cooling gun 21; when the real-time temperature exceeds the limit (the established temperature, initially set to 100°C), the sound and light alarm 33 alarms to remind the operator to take other methods to cool down while water cooling is performed. When the temperature drops from above 85° C. to 85° C., the water-cooling cooling gun 22 is turned off and the air-cooling cooling gun 21 is started. When the temperature is below 45° C., the air-cooling cooling gun 21 is turned off to allow the workpiece to cool naturally.
[0025] The controller can control the cooling water and compressed air pipelines in different levels, and adopt different cooling measures for the workpiece according to different temperature ranges to achieve graded cooling of the workpiece. The controller controls the multi-media intelligent cooling device to perform graded cooling for different temperature ranges of the workpiece, and the temperature change can be controlled within ±0.5℃, realizing the automatic temperature control function of the workpiece.
[0026] The magnetic seat and the infrared temperature detector 31 are electromagnetically adsorbed at the oil seal position on the surface of the reducer, which is the same as the electromagnetic adsorption used, and is a mature technology in the prior art, and does not belong to the technical improvement of the utility model, and is not described in detail in the utility model.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
