Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vacuum pipeline process equipment for maglev trains, and more specifically, to a rotary isolation gate valve for vacuum pipelines of high-speed maglev trains. Background Technology
[0002] Before entering the vacuum tube, the maglev train needs to be isolated by a partition device to form a transition chamber. The transition chamber helps the train adapt to the two different environments of atmospheric pressure and vacuum, thereby avoiding the impact of pressure changes when the train enters and exits the vacuum tube.
[0003] In existing vacuum tube maglev trains, the push-pull partition structure requires cutting the train track inside the vacuum tube to achieve a sealing effect when closed. When the partition structure is opened, there will be gaps in the track. After long-term operation, it is difficult to guarantee the precision of the gaps, which is not conducive to the stability of train operation. Utility Model Content

[0024] Example 1:
[0025] like Figures 1 to 3 As shown, this embodiment provides a grouting and water-blocking device suitable for surface drilling in metal mines, including: a housing 1, a drive assembly, a partition plate, and a telescopic assembly. The housing 1 connects two adjacent carriage pipes, and the housing 1 has a passage opening for trains and tracks to pass through. A first drive assembly 31 is disposed on the side edge of the passage opening, and the position of the first drive assembly 31 is flush with the top of the track vertical wall. The partition plate includes a first plate 21 and a second plate 22. The partition plate is configured as an arc, and the partition plate rotates about the endpoint of one of the arcs as an axis. The partition plate is connected to the first drive assembly 31 through the rotation axis. The telescopic assembly connects the first plate 21 and the second plate 22, and the telescopic assembly can drive the second plate 22 to extend or retract from the lower end of the first plate 21.
[0026] like Figures 1 to 3 As shown, this utility model connects two adjacent carriage pipes through the housing 1. The drive assembly drives the partition plate to rotate, realizing the switching of the vacuum pipe partition state. The partition plate is set as a telescopic double plate. The telescopic assembly can drive the second plate 22 to extend or retract from the lower end of the first plate 21. After the chord of the first plate 21 falls on the top surface of the track vertical wall, the telescopic assembly drives the second plate 22 to extend from the lower end of the first plate 21, so that the passage opening is closed. When the passage opening needs to be opened, the telescopic assembly drives the second plate 22 to retract from the lower end of the first plate 21. Without affecting the partition effect, it reduces the storage space of the partition structure and improves the adaptability of the vacuum pipe to the civil engineering size. At the same time, the lower end of the partition plate of this utility model is provided with a groove that fits the shape of the track, avoiding cutting the track inside the vacuum pipe and ensuring the stability of train operation.
[0027] Example 2:
[0028] This embodiment is a further optimization based on Embodiment 1, specifically as follows: Figure 3 As shown, the diameter of the first plate 21 is greater than or equal to the diameter of the channel opening, the second plate 22 is set as a rectangle, the length of the second plate 22 is equal to the spacing of the track vertical walls, and the width is greater than or equal to the height of the track vertical walls. The first plate 21 and the second plate 22 can maintain a vacuum state when the channel opening is closed.
[0029] Example 3:
[0030] This embodiment is a further optimization based on Embodiment 1, specifically as follows: Figure 2 and Figure 3 As shown, the size of the second plate 22 is smaller than that of the first plate 21. The lower end of the first plate 21 is provided with a groove for the second plate 22 to retract. When the second plate 22 is retracted, the partition plate presents itself as a complete bow-shaped plate.
[0031] Example 4:
[0032] This embodiment is a further optimization based on Embodiment 1, specifically as follows: Figure 2 and Figure 3 As shown, the lower end of the second plate 22 is provided with a groove that fits the shape of the track, which avoids cutting the track inside the vacuum pipe and ensures the stability of the train operation.
[0033] Example 5:
[0034] This embodiment is a further optimization based on Embodiment 1, specifically as follows: Figure 1 and Figure 2 As shown, the driving assembly includes a first driving assembly 31, a second driving assembly 32, a first connecting rod 23, and a second connecting rod 24. The second driving assembly 32 is disposed between the channel opening and the housing 1, and the second driving assembly 32 is positioned lower than the first driving assembly 31. One end of the first connecting rod 23 is connected to the second driving assembly 32, and the other end is connected to one end of the second connecting rod 24 and fixed to the arc edge of the partition plate. One end of the second connecting rod 24 is connected to one end of the first connecting rod 23 and fixed to the arc edge of the partition plate, and the other end is fixed to the endpoint of the arc of the first plate 21 that is not the axis of rotation. The driving assemblies jointly drive the partition plate to rotate. The first driving assembly 31 and the second driving assembly 32 are configured as rotary motors.
[0035] This utility model can be regarded as a four-bar linkage mechanism composed of "first drive assembly 31-second drive assembly 32", the chord of the bow-shaped partition plate, the first connecting rod 23, and the second connecting rod 24. The "first drive assembly 31-second drive assembly 32" is the frame of the four-bar linkage mechanism. The chord of the bow-shaped partition plate and the first connecting rod 23 are rockers, and the second connecting rod 24 is a connecting rod. When the first drive assembly 31 and the second drive assembly 32 rotate clockwise, the partition plate moves clockwise with the four-bar linkage mechanism until the passage is fully opened. When the first drive assembly 31 and the second drive assembly 32 rotate counterclockwise, the partition plate moves counterclockwise with the four-bar linkage mechanism until the chord of the first plate 21 falls on the top surface of the track vertical wall.
[0036] Example 6:
[0037] This embodiment is a further optimization based on Embodiment 1, specifically as follows: Figure 1 As shown, a stop device 4 is provided on the inner side wall of the housing 1, which prevents the partition plate from hitting the inner side wall of the housing 1 while ensuring that the opening of the partition plate does not affect the normal operation of the train, limits the rotation angle of the partition plate, and reduces the storage space of the partition device.
[0038] Example 7:
[0039] This embodiment is a further optimization based on Embodiment 1, specifically as follows: Figures 1 to 3 As shown, a traction system is provided inside the housing 1. The traction system is a pulley block, which is fixedly installed on the inner top surface of the housing 1. A traction rope is provided on the pulley block, with one end of the traction rope connected to the first plate 21 and the other end connected to the gravity device 53.
[0040] The pulley system includes a first fixed pulley 51 and a second fixed pulley 52. The two fixed pulleys are arranged parallel to the cross-section of the partition plate. The first fixed pulley 51 is positioned on the same vertical line as the first drive assembly 31. The second fixed pulley 52 is disposed between the first fixed pulley 51 and the inner wall of the housing 1. The traction system can effectively reduce the load on the drive assembly when opening or closing the partition plate.
