Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of vacuum sealing, and relates to a quick installation device for a flange sealing ring of a suspended transportation vacuum pipeline. BACKGROUND

[0002] At present, major economic and technological powers in the world have carried out relevant technical research and industrial development. Since the size of the pipeline is large (the diameter is not less than 5 m), the sealing ring at the flange connection of the pipeline is large in size, which is more difficult to install than a small sealing ring. The installation quality of the sealing ring directly determines the sealing performance of the train pipeline. The speed of the sealing ring installation directly determines the construction period during the initial construction and the length of time consumed during the subsequent maintenance process. The traditional sealing ring installation method is to directly use a rubber hammer to pound the sealing ring into the sealing groove. Due to the impact, this process can easily affect the performance of the pipe beam. If there are iron residues in the sealing groove, the sealing ring will be directly damaged during the process of being pounded into the sealing groove, thereby losing the sealing performance. Therefore, a special installation device is urgently needed to quickly and high-quality install a large-size flange sealing ring in the sealing groove of the flange. This can not only ensure that the train pipeline can obtain good vacuum sealing performance, but also save a large amount of installation time of the large-size flange sealing ring and reduce the work intensity of the construction personnel.

[0033] like Figure 1a , 1b As shown in 1c, 1d, 2a, 2c, 2b, and 2d, in one embodiment of the present invention, a quick installation device for a flange sealing ring of a suspended transport vacuum pipeline is provided. This installation device includes a rolling clamping device 200 and at least two single-point positioning devices 100, wherein: at least two single-point positioning devices 100... Symmetrically arranged on the flange, each of the single-point positioning devices 100 includes a clamping assembly 10, a first sliding part 20, and a pressure applying assembly 30. The clamping assembly 10 clamps onto the flange, and the first sliding part 20 is slidably disposed on the clamping assembly 10. The first sliding part 20 can slide on the clamping assembly 10 along the radial direction of the flange. The pressure applying assembly 30 is rotatably connected to the first sliding part 20. The pressure applying assembly 30 is used to press part of the sealing ring into the sealing groove to achieve single-point positioning before the sealing ring is installed. The rolling pressing device 200 includes a rolling assembly 50, a second sliding part 60, a rolling pressing assembly 70, and a positioning part 80. The rolling assembly 50 is disposed on the sealing surface of the flange and can move circumferentially along the flange. The second sliding part 60 is slidably disposed on the rolling assembly 50. The second sliding part 60 can slide on the rolling assembly 50 along the radial direction of the flange. The positioning part 80 is detachably connected to one end of the second sliding part 60. A through hole is formed between the positioning part 80 and one end of the second sliding part 60. The sealing ring is fitted inside the through hole. The rolling pressing assembly 70 is connected to the second sliding part 60. The rolling pressing assembly 70 and the positioning part 80 are located on both sides of the rolling assembly 50, respectively. The rolling pressing assembly is used to press the sealing ring into the sealing groove.

[0034] That is, the single-point positioning device 100 is used for single-point positioning before the sealing ring is installed, and the rolling pressing device 200 is used for the installation of the sealing ring. When the sealing ring is installed, the single-point positioning of the sealing ring is first completed by at least two single-point positioning devices 100, and then the installation of the sealing ring is completed by the rolling pressing device 200.

[0035] In this embodiment, since the pressure-applying component 30 is rotatably connected to the first sliding part 20, the first sliding part 20 can slide on the clamping component 10 along the radial direction of the flange. The movement of the first sliding part 20 can drive the pressure-applying component 30 to move along the radial direction of the flange, thereby adjusting the position of the pressure-applying component 30 so that the pressure-applying component 30 is located above the sealing ring, so as to accurately press the sealing ring into the sealing groove. Furthermore, since the pressure-applying component 30 is rotatably connected to the first sliding part 20, the distance between the pressure-applying part and the sealing ring can be adjusted by rotating the pressure-applying part, so as to press the sealing ring into the sealing groove.

[0036] In this embodiment, the single-point positioning device 100 performs single-point positioning of the sealing ring before installation, ensuring that the rolling clamping device 200 can quickly complete the installation of the sealing ring. In the design of the rolling clamping device 200, the rolling assembly 50 is positioned on the sealing surface of the flange, the second sliding part 60 is slidably mounted on the rolling assembly 50, and the rolling clamping assembly 70 is connected to the second sliding part 60. Therefore, the movement of the rolling assembly 50 can drive the rolling clamping assembly 70 to move along the circumferential direction of the flange, and the sliding of the second sliding part 60 can drive the rolling clamping assembly 70 to move along the radial direction of the flange. This allows adjustment of the position of the rolling clamping assembly 70 and completion of the sealing ring installation along the circumferential direction of the flange. The positioning part 80 is designed to be detachably connected to one end of the second sliding part 60, and a through hole is formed between the positioning part 80 and one end of the second sliding part 60. The sealing ring is fitted into the through hole. Thus, before the sealing ring is installed, one end of the positioning part 80 and the second sliding part 60 are not connected. When the sealing ring is fitted into the through hole, the positioning part 80 and the second sliding part 60 are fixed together. This ensures the positioning of the sealing ring during the movement of the rolling pressing device 200. In this way, the rolling pressing device 200 can accurately complete the installation of the sealing ring while moving.

[0037] For example, the positioning part 80 can be an arc-shaped support plate, and one end of the second sliding part 60 is an arc-shaped structure. The arc-shaped support plate and the arc-shaped structure are connected by a set screw, and a circular through hole is formed between them.

[0038] Furthermore, the number of single-point positioning devices 100 can be designed according to the flange size; the larger the flange size, the more single-point positioning devices 100 are required. Specifically, the number of single-point fixing devices to be used needs to be determined based on the size of the flange on site. The purpose of determining the number is to fix the flange sealing ring of the suspended transport vacuum pipeline to the vicinity of the sealing groove, facilitating the subsequent pressing operation of the rolling pressing device 200.

[0039] By applying the embodiments of the present invention, the first sliding part 20 is slidably disposed on the clamping assembly 10, and the first sliding part 20 can slide on the clamping assembly 10 along the radial direction of the flange. The pressure application assembly 30 is rotatably connected to the first sliding part 20. Thus, the first sliding part 20 and the pressure application assembly 30 cooperate to accurately press the sealing ring into the sealing groove. By setting at least two single-point positioning devices 100 symmetrically arranged on the flange, the multiple single-point positioning devices 100 cooperate to press the symmetrical multi-point sealing ring into the sealing groove, thereby realizing single-point positioning during the initial installation of the sealing ring of a large-size flange. Simultaneously, the rolling assembly 50 is designed to move circumferentially along the flange, and the second sliding part 60 is slidably disposed on the rolling assembly 50. The second sliding part 60 slides on the rolling assembly 50 radially along the flange. The rolling pressing assembly 70 is connected to the second sliding part 60, and a through hole is formed between the positioning part 80 and one end of the second sliding part 60. The sealing ring is fitted into the through hole. Thus, the positioning part 80 and the second sliding part 60 cooperate to position the sealing ring. The movement of the rolling assembly 50 drives the rolling pressing assembly 70 to move circumferentially along the flange. During the movement, the rolling pressing assembly 70 presses the large-sized sealing ring into the sealing groove of the flange sealing surface, thereby quickly realizing the installation of the flange sealing ring. Compared with the traditional construction method in which construction workers use rubber mallets to hammer the sealing ring into the sealing groove in sections, the device of this invention has a faster execution speed and saves the number of construction workers.

[0040] In the above embodiments, in order to ensure that the clamping assembly 10 is flexibly and reliably clamped on the flange, the clamping assembly 10 includes a clamping body 11 and a first pressure-applying part 12. The clamping body 11 includes a main body, a first clamping side and a second clamping side. The first sliding part 20 is slidably disposed on the main body. The first clamping side and the second clamping side are respectively connected to both ends of the main body. The first clamping side and the second clamping side are both perpendicular to the main body. The first pressure-applying part 12 is rotatably connected to the second clamping side. The clamping assembly 10 is clamped on the flange by the cooperation of the first pressure-applying part 12 and the first clamping side.

[0041] For example, the main body, the first clamping side, and the second clamping side are integrally formed.

[0042] In this embodiment of the invention, since the first pressure-applying part 12 is rotatably connected to the second clamping side, by rotating the first pressure-applying part 12, the distance between the first pressure-applying part 12 and the first clamping side can be adjusted. The flange is clamped by the first pressure-applying part 12 and the first clamping side, thereby ensuring that the clamping assembly 10 is flexibly and reliably clamped on the flange and can adapt to flanges of different sizes, that is, it can be fixed on flanges of any size.

[0043] As a specific embodiment of the present invention, the first sliding part 20 can be a sliding rod. The connection between the sliding rod and the body is similar to that of a linear slide rail, which allows the sliding rod to slide freely in the track groove of the body at the upper end of the clamping body 11, thereby adjusting the pressure application component 30 directly above the sealing ring to prepare for the pressing operation.

[0044] In the above embodiment, in order to better achieve single-point positioning before the sealing ring is installed, the pressure application component 30 includes a second pressure application part 31 and a third pressure application part 32. Both the second pressure application part 31 and the third pressure application part 32 are rotatably connected to the first sliding part 20. The first pressure application part 12 and the second pressure application part 31 are distributed on both sides of the body. Both the first pressure application part 12 and the second pressure application part 31 are used to press part of the sealing ring into the sealing groove.

[0045] In this embodiment of the invention, since both the second pressing part 31 and the third pressing part 32 are rotatably connected to the first sliding part 20, the distance between the two and the sealing ring can be adjusted by rotating the second pressing part 31 and the third pressing part 32, thereby pressing the sealing ring into the sealing groove. Moreover, the first pressing part 12 and the second pressing part 31 are distributed on both sides of the body, which can ensure uniform single-point positioning.

[0046] In one specific embodiment of the present invention, each of the first pressure-applying part 12, the second pressure-applying part 31, and the third pressure-applying part 32 includes a top block and a handle rod. The handle rod includes a handle and a rod portion connected together. The rod portion is also connected to the top block. The rod portion of the first pressure-applying part 12 is rotatably connected to the second clamping side, and the rod portions of the second pressure-applying part 31 and the third pressure-applying part 32 are rotatably connected to the first sliding part 20.

[0047] For example, for the first pressure application part 12, the distance between the top block and the first clamping side can be adjusted by rotating the handle rod; for the second pressure application part 31 and the third pressure application part 32, the distance between the top block and the sealing ring can be adjusted by rotating the handle rod, and the designed top block can also be used for the installation of large-size sealing rings with different cross-sectional shapes.

[0048] In addition, all of the above-mentioned handle rods can be connected to the corresponding components via threads.

[0049] In the above embodiment, in order to avoid damage to the flange, the clamping assembly 10 further includes an elastic pad 13, which is connected to the first clamping side. The elastic pad 13 cooperates with the top block of the first pressure part 12 to clamp the clamping assembly 10 onto the flange.

[0050] For example, the elastic pad 13 can be fixed to the inner side of the first clamping side by an internal hexagonal head bolt. The elastic pad 13 and the top block of the first pressure part 12 cooperate, and the distance between them can be adjusted by the handle rod of the first pressure part 12, thereby enabling the clamping assembly 10 to be clamped on the flange and avoiding damage to the flange surface.

[0051] In one specific embodiment of the present invention, the elastic pad 13 includes a nylon pad.

[0052] In the above embodiment, in order to realize the rolling assembly 50 moving circumferentially along the flange, the rolling assembly 50 includes a rotating frame 40, a first roller assembly 51, a second roller assembly 52, a shaft 53, and a handle rod 54. The second sliding part 60 is slidably disposed on the rotating frame 40. The handle rod 54 includes a handle and a rod portion connected together. The rod portion is also connected to the first roller assembly 51. The rod portion is also rotatably connected to a first end of the rotating frame 40. The shaft 53 is connected to a second end of the rotating frame 40. The second roller assembly 52 is connected to the shaft 53. The first roller assembly 51 and the second roller assembly 52 cooperate to make the rolling assembly 50 move circumferentially along the flange.

[0053] For example, the handle lever can be connected to the rotating frame 40 via a thread.

[0054] In this embodiment of the invention, since the first roller assembly 51 is connected to the rotating frame 40 via the handle rod 54, and the second roller assembly 52 is connected to the rotating frame 40 via the shaft 53, both the first roller assembly 51 and the second roller assembly 52 are disposed on the flange sealing surface. Thus, the movement of the first roller assembly 51 and the second roller assembly 52 drives the rotating frame 40 to move together along the flange circumferentially. Moreover, since the handle rod 54 is rotatably connected to the rotating frame 40, the distance between the first roller assembly 51 and the second roller assembly 52 can be adjusted by rotating the handle rod 54, thereby enabling the rolling assembly 50 to roll on a flange of any size.

[0055] In the above embodiments, in order to achieve reliable installation and rolling of the first roller assembly 51 and the second roller assembly 52, the first roller assembly 51 includes a first roller 511 and a first retaining ring 512. The first roller 511 is sleeved on the rod portion, and there is a small clearance fit between the first roller 511 and the rod portion. The first retaining ring 512 is embedded on the rod portion and is used to stop the first roller 511. The second roller assembly 52 includes a second roller 521 and a second retaining ring 522. The second roller 521 is sleeved on the shaft 53, and there is a small clearance fit between the second roller 521 and the shaft 53. The second retaining ring 522 is embedded on the shaft 53 and is used to stop the second roller 521.

[0056] That is, the first roller 511 is fitted onto the rod with a small clearance between the first roller 511 and the rod, and the first roller 511 is stopped by the first retaining ring 512 (to prevent the first roller 511 from coming off the rod). The second roller 521 is fitted onto the shaft 53 with a small clearance between the second roller 521 and the shaft 53, and the second roller 521 is stopped by the second retaining ring 522 (to prevent the second roller 521 from coming off the shaft 53). This achieves reliable installation and rolling of the first roller assembly 51 and the second roller assembly 52.

[0057] According to a specific embodiment of the present invention, both the first retaining ring 512 and the second retaining ring 522 are elastic retaining rings.

[0058] In the above embodiment, in order to ensure the rolling of the rolling pressing assembly 70 and the pressing of the sealing ring, the rolling pressing assembly 70 includes a vertical bearing 71, a roller 72 and a handle 73. The vertical bearing 71 includes a seat and a shaft 53 bearing. The handle 73 is connected to the second sliding part 60 and the seat respectively. The roller 72 is connected to the shaft 53 bearing. The roller 72 is used to press the sealing ring into the sealing groove.

[0059] For example, the handle 73 can be fixedly connected to the second sliding part 60 and the seat by an internal hex socket head cap screw.

[0060] As can be seen, by gripping the handle 73 tightly and pressing down, the roller 72 located at the rear of the rolling pressing device 200 is pressed against the sealing ring that is to be pressed into the sealing groove; while pressing down the rolling pressing device 200, it is slowly pushed forward until the entire sealing ring is pressed into the sealing groove.

[0061] like Figure 3 As shown, Figure 3 A schematic diagram illustrating the quick installation of a flange sealing ring according to a specific embodiment of the present invention is shown.

[0062] By adjusting the top block in the single-point fixing device to be directly above the sealing ring to be pressed, the pressing operation is prepared; tightening the handle rod allows the top block to be pressed into the sealing groove, thus achieving the single-point positioning operation before the sealing ring is installed.

[0063] By rotating the handle of the rolling pressing device 200, the roller at its end is fixed to the roller of the rotating frame 40 on the through shaft 53 and stably abuts against the sealing surface of the flange. Adjust the two rollers until they can slide freely without wobbling left and right. At this time, hold the handle 73 tightly and press down, so that the roller 72 at the rear of the rolling pressing device 200 is pressed into the sealing groove. While pressing down the rolling pressing device 200, push it forward slowly until the entire sealing ring is pressed into the sealing groove. In addition, before the sealing ring is installed, the support plate and one end of the second sliding part 60 are connected by a set screw, forming a through hole between them, which provides guidance for the part of the flange sealing ring of the suspended transport vacuum pipeline to be pressed, so that it can be accurately pressed into the sealing groove on the flange. When fixing the rolling pressing device 200 to the flange, the set screw needs to be loosened, the sealing ring needs to be sent into the through hole, and then the support plate and one end of the second sliding part 60 can be fixed by the set screw.

[0064] In the aforementioned quick installation device for the flange sealing ring of the suspended transport vacuum pipeline, the number of single-point fixing devices to be used needs to be determined according to the size of the flange on site. The purpose of determining the number of devices is to fix the flange sealing ring of the suspended transport vacuum pipeline near the sealing groove, so as to facilitate the subsequent pressing operation of the rolling pressing device 200.

[0065] In summary, the device of this invention comprises two parts: a single-point fixing device and a rolling pressing device. When working together, they can achieve rapid installation of flange sealing rings for suspended transport vacuum pipelines. First, the single-point positioning device fixes the large-size sealing ring to the flange sealing surface and presses at least two symmetrical points into the sealing groove, thereby achieving single-point positioning of the large-size flange sealing ring during initial installation. Then, by pushing the rolling pressing device forward along the inner and outer circumferential sides of the flange, the large-size sealing ring is pressed into the sealing groove of the flange sealing surface. The entire process is simple to operate. Compared with the traditional construction method where construction workers use rubber mallets to hammer the sealing ring into the sealing groove in sections, this device is faster and saves on the number of construction workers.

[0066] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0067] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0068] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
