Description

Technical Field

[0001] The present invention relates to the technical field of motion mechanisms, and specifically to a motion mechanism applied to a low-temperature vacuum environment. Background Technique

[0002] Low temperature, commonly known as cold, according to the regulations of China's meteorological department, any strong cold air that causes a temperature drop of more than 10°C within 24 hours or more than 12°C within 48 hours in a local area, and the lowest temperature drops below 5°C, is called a cold wave. Low-temperature operation refers to an operation where the average temperature at the work location is equal to or lower than 5°C during the production labor process. According to the temperature at the work location and the low-temperature operation time rate, low-temperature operations can be divided into 4 levels, and the higher the level, the greater the cold intensity.

[0003] The meaning of vacuum refers to the gas state with a pressure lower than one atmospheric pressure in a given space, which is a physical phenomenon. In the "void", sound cannot be transmitted because there is no medium, but the transmission of electromagnetic waves is not affected by the vacuum. In fact, in vacuum technology, vacuum is relative to the atmosphere. When a part of the matter inside a specific space is exhausted, making its pressure less than one standard atmospheric pressure, we generally call this space vacuum or vacuum state. Vacuum is commonly measured in Pascal or Torr as the unit of pressure. In the natural environment, only outer space can be regarded as the space closest to vacuum.

Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0026] As Figures 1-5As shown in the figure, the motion mechanism applied to the low-temperature vacuum environment of the present invention may include a vacuum container 1, a driving assembly 2, a cold plate 3, a driven assembly 4, a driving mechanism heat preservation member 5, and a driven mechanism heat preservation member 6. Both ends of the cold plate 3 are respectively connected to the driving assembly 2 and the driven assembly 4. The driving mechanism heat preservation member 5 is arranged on the driving assembly 2 to keep the driving assembly 2 at a certain temperature. The driven mechanism heat preservation member 6 is arranged on the driven assembly 4 to keep the driven assembly 4 at a certain temperature. The driving assembly 2 and the driven assembly 4 are respectively fixed on the inner wall of the vacuum container 1.

[0027] More specifically, as Figure 2 shown, the driving assembly 2 may include a first mounting seat 21, a driving mechanism 22, a transmission assembly 23, a second mounting seat 24, a driving guide rail 25, a rack 26, a gear 27, a first connecting plate 28, and a first rolling wheel 29. The driving mechanism 22 is fixedly connected to the inner wall of the vacuum container 1 through the first mounting seat 21. The driving mechanism 22 includes a motor and a speed reducer. The transmission assembly 23 includes a transmission shaft and a transmission shaft mounting seat. The transmission shaft mounting seat is fixed on the first mounting seat 21 and the driving guide rail 25 to fix the transmission shaft. One end of the transmission shaft of the transmission assembly 23 is connected to the output end of the speed reducer, and the other end is in transmission connection with the gear 27. One end of the first connecting plate 28 is connected to the cold plate 3, and the other end is in transmission connection with the first rolling wheel 29. The first rolling wheel 29 is arranged on the driving guide rail 25, and the first connecting plate 28 is fixedly connected to the rack 26. The gear 27 cooperates with the rack 26.

[0028] A plurality of second mounting seats 24 (three are shown in the figure) are arranged on the driving guide rail 25. The driving guide rail 25 is fixedly connected to the inner wall of the vacuum container 1 through 24.

[0029] There may be a plurality of the first connecting plates 28 (two are shown in the figure). Each first connecting plate 28 is connected to two first rolling wheels 29. The two first rolling wheels 29 are respectively located on the tracks on both sides of the main body of the driving guide rail 25, so that the first connecting plate 28 is hung on the driving guide rail 25 through the two first rolling wheels 29. Thus, the transmission assembly 23 can drive the first connecting plate 28 and the first rolling wheel 29 to slide along the driving guide rail 25.

[0030] Refer to Figure 4, the driven assembly 4 may include a third mounting seat 41 (there may be multiple, 3 are shown in the figure), a driven guide rail 42, a second connecting plate 43, and a second rolling wheel 44. The second rolling wheel 44 is fixedly connected to the lower end of the connecting plate 28. As shown in the figure, the driven guide rail 42 is fixedly connected to the inner wall of the vacuum container 1 through the third mounting seat 41; two second rolling wheels 44 are respectively arranged on both sides of the main body of the driven guide rail 42. The second connecting plate 43 is in rolling connection with the driven guide rail 42 through the second rolling wheels 44. The upper end of the second connecting plate 28 is fixedly connected to the cold plate 3. Thus, the transmission assembly 23 can drive the cold plate 3 to slide along the driving guide rail 25 and the driven guide rail 42.

[0031] Reference Figure 3 , the driving mechanism heat preservation member 5 includes a heat preservation cover and a heating device (not shown), which can keep the driving assembly 2 at a certain temperature, for example, above 0 degrees Celsius. The heat preservation cover is made of heat preservation and heat-resistant materials (such as organic polymer materials like phenolic resin foam board, polystyrene extruded board, and inorganic materials such as ceramic heat preservation board, etc.). The heating device can be arranged inside the heat preservation cover. For example, it can be an electric heating element to provide heat for the driving assembly 2. As Figure 3 shown, the heat preservation cover basically encapsulates the transmission assembly 23, the driving guide rail 25, the rack 26, the gear 27, and the first rolling wheel 29. Thus, it can prevent the movement mechanism from getting stuck in a low-temperature environment. In addition, in order not to interfere with the movement of the first connecting plate 28, a slit (not shown) is formed on the bottom surface of the heat preservation cover.

[0032] Reference Figure 5 , the driven mechanism heat preservation member 6 includes a heat preservation cover and a heating device, which can keep the driven assembly 4 at a certain temperature, for example, the temperature reaches 0 degrees Celsius. The heat preservation cover is made of heat preservation and heat-resistant materials. The heating device can be arranged inside the heat preservation cover. For example, it can be an electric heating element to provide heat for the driving assembly 2. As Figure 3 shown, the heat preservation cover basically encapsulates the driven guide rail 42 and the second rolling wheel 44. Thus, it can prevent the movement mechanism from getting stuck in a low-temperature environment. In addition, in order not to interfere with the movement of the second connecting plate 43, a slit is formed on the top surface of the heat preservation cover.

[0033] It should be noted that for a motion mechanism applied to a low-temperature vacuum environment, during operation, both ends of the cold plate 3 are respectively connected to the driving assembly 2 and the driven assembly 4. The driving assembly 2 includes a driving mechanism 22, a transmission assembly 23, a driving guide rail 25, a rack 26, a gear 27, a first connecting plate 28, and a first rolling wheel 29. The driving mechanism 22 includes a motor and a speed reducer. The transmission assembly 23 includes a transmission shaft and a transmission shaft mounting seat. One end of the transmission shaft of the transmission assembly 23 is connected to the output end of the speed reducer, and the other end is in transmission connection with the gear 27. One end of the first connecting plate 28 is connected to the cold plate 3, and the other end is in transmission connection with the first rolling wheel 29. The first rolling wheel 29 is arranged on the driving guide rail 25, and the first connecting plate 28 is fixedly connected to the rack 26. The gear 27 cooperates with the rack 26. Thus, the transmission assembly 23 can drive the first connecting plate 28 and the first rolling wheel 29 to slide along the driving guide rail 25. The driven assembly 4 includes a driven guide rail 42, a second connecting plate 43, and a second rolling wheel 44. The rolling wheel 29 is fixedly connected to the lower end of the connecting plate 28, and the second connecting plate 43 is in rolling connection with the driven guide rail 42 through the second rolling wheel 44. The upper end of the second connecting plate 28 is fixedly connected to the cold plate 3. The driving mechanism heat preservation member 5 and the driven mechanism heat preservation member 6 both include a heat preservation cover and a heating device, which can make the temperature of the driving assembly 2 and the driven assembly 4 reach above 0 degrees Celsius.
