Description

Technical Field

[0001] This application relates to the field of vacuum pump technology, and specifically to a vacuum pump assembly installation device. Background Technology

[0002] In existing technologies, pump sets often require stacking Roots pumps to improve cavitation efficiency. This simple stacking of pump bodies results in a relatively simple connection method, but the installation structure between the pump bodies is unstable, reducing the operational stability of the pump set. Furthermore, the overall weight of the stacked pump set increases significantly, and the numerous, small wheels make movement difficult and inflexible. Therefore, when it is necessary to move the pump set, heavy equipment such as forklifts are usually used for assistance. The forklift extends under the pump set to lift it, thus enabling movement.

[0003] However, this method of movement is complicated to operate, has high forklift operating costs and requires a large space. In addition, the repeated insertion of the forklift into the bottom of the pump unit will cause wear on the bottom of the pump unit and increase the probability of pump damage.

[0004] Therefore, there is room for further improvement in the installation structure and movement method of multi-pump pump sets in the existing technology. Utility Model Content

[0005] In view of this, and in response to the technical problems of unstable installation structure between pump bodies in the existing pump sets, the need for forklift assistance for movement, which increases transportation costs and greatly increases the probability of equipment damage, this application provides a vacuum pump set installation device that can install the pump set and change the height of the base pump so that the base pump is off the ground, so as to facilitate the installation device to drive the pump set to move.

[0006] This application provides a vacuum pump assembly installation device, including: Install rack; Rollers are located at the bottom of the mounting frame; Top bracket, connected to the mounting frame, used to mount the top pump; The bottom bracket, spaced apart at the lower end of the top bracket, is used to install the bottom pump; A connecting bracket extends vertically toward the bottom of the mounting frame to connect the bottom support to the mounting frame; An adjustment mechanism, located between the bottom bracket and the connecting frame, is used to adjust the installation height of the bottom bracket on the connecting frame.

[0007] Compared with the prior art, the vacuum pump assembly installation device of this application has a top bracket for mounting a top pump and a bottom bracket for mounting a bottom pump, thereby realizing the installation of the pump assembly. Both the top and bottom brackets are connected to the mounting frame. Compared with the existing structure of two stacked pump bodies, the top bracket, bottom bracket, and mounting frame can provide multi-angle and multi-directional support for the pump bodies, improving the installation stability between the pump bodies. The bottom of the mounting frame is equipped with rollers, which can push the mounting frame to move, thereby moving the vacuum pump assembly. This eliminates the need for forklifts or other auxiliary equipment to move the vacuum pump assembly, greatly reducing transportation costs, simplifying the transportation process, and reducing the probability of wear and tear on the pump assembly during movement. Furthermore, in this application, the connecting frame extends vertically, enabling the bottom bracket to be positioned... The bottom bracket is lowered to support the bottom of the base pump. The base bracket is connected to the connecting frame via an adjustment mechanism, which allows for easy adjustment of the distance between the base pump and the ground. When the pump unit needs to be moved, the adjustment mechanism raises the base bracket on the connecting frame, allowing the rollers at the bottom of the base pump to lift off the ground without adjusting the entire mounting frame base. This simplifies adjustment, saves costs, and prevents interference between the base pump rollers and the mounting frame during movement, facilitating flexible and rapid movement. Furthermore, by raising the height of the base pump during movement, it connects the base pump and the top pump as a single unit, preventing damage to the bellows between the two pumps due to improper operation.

[0008] Preferably, the adjustment mechanism includes: The connecting column is threaded to the bottom bracket and rotatably connected to the connecting frame; A limiting block, located at the end of the connecting column, is used to limit the vertical displacement of the connecting column.

[0009] In this embodiment, the connecting column can rotate around its axis as the center of rotation under the action of the limiting block, but will not be displaced axially. Therefore, the connecting column can be rotated, and the bottom bracket can be displaced axially along the connecting column through the threaded connection between the connecting column and the bottom bracket, thereby changing the vertical installation height of the bottom bracket on the connecting frame.

[0010] Preferred options also include: An adjustment hole is provided on the connecting frame, with its axis perpendicular to the vertical direction and its length extending in a direction parallel to the vertical direction; The mounting hole is located on the bottom bracket, and its axis is parallel to the axis of the adjustment hole. The connectors pass through the adjustment holes and mounting holes in sequence to connect the bottom bracket to the connecting frame; The outer diameter of the connector is smaller than the length of the adjustment hole, and the connector can be displaced along the length direction of the adjustment hole.

[0011] In this embodiment, the adjustment hole is a strip-shaped hole with adjustable installation space in the vertical direction. With the cooperation of the connecting column and the connecting piece, it can realize the movement stability of the bottom bracket and ensure the connection stability between the bottom bracket and the connecting frame.

By changing the fixing holes installed with the connecting brackets, the installation distance between the two sets of connecting brackets can be changed to adapt to pump bodies of different sizes.

[0014] Preferred options also include: The limiting hole is located on the connecting frame, with its axis parallel to the vertical direction and its outer diameter greater than or equal to the inner diameter of the connecting column; A connecting hole is provided on the bottom bracket, with its axis on the same straight line as the limiting hole, and its inner wall is provided with an internal thread; the connecting column is provided with an external thread that mates with the internal thread. The first fastening nut is fixedly connected to the bottom bracket and is coaxially set with the connecting hole.

[0015] In this embodiment, by fixing a first fastening nut to one side of the connecting hole, the thread setting length of the bottom bracket can be increased to ensure the connection stability with the connecting column.

[0016] Preferred options also include: The second fastening nut is fixedly connected to the bottom bracket and is coaxially set with the mounting hole; The connector includes a limiting part and a connecting part. The limiting part is connected to any end of the connecting part. The outer diameter of the limiting part is larger than the outer diameter of the connecting part. The connecting part is threadedly connected to the first fastening nut.

[0017] In this embodiment, by providing a second fastening nut on one side of the mounting hole, the thread length at the mounting hole can be increased to ensure the connection stability between the connector and the bottom bracket.

[0019] In this embodiment, the first limiting plate can be connected to the mounting frame, and the second limiting plate can be connected to the connecting column. The second limiting plate provides a vertical limiting effect on the connecting column to ensure that the connecting column can be stably connected to the connecting frame. The connecting side plate increases the structural strength of the connecting frame while increasing the connection area and connection stability with the bottom support.

[0020] Preferably, there is a gap between the top of the connecting side plate and the first limiting plate; There is a gap between the bottom of the connecting side plate and the bottom of the connecting vertical plate, and the bottom of the connecting side plate extends beyond the bottom of the connecting vertical plate; The adjustment hole is located on the part of the connecting side plate that extends beyond the bottom of the connecting vertical plate.

[0021] In this embodiment, the distance between the top of the connecting side plate and the first limiting plate is used to accommodate the mounting frame, and the gap between the bottom of the connecting side plate and the bottom of the connecting vertical plate can accommodate the bottom bracket, so that the bottom bracket can be located between the two connecting side plates, thereby improving the connection stability between the bottom bracket and the connecting frame.

[0022] Preferably, the bottom support includes: A support plate, parallel to the second limiting plate, is used to support the bottom of the bottom pump; Support side plates are set parallel to the connecting side plates and are located at opposite ends of the support cross plate; The connecting hole and the first fastening nut are provided on the support cross plate, and the mounting hole and the second fastening nut are provided on the support side plate.

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

They are only for the convenience of describing this application and simplifying the description, and 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. Therefore, the above terms should not be construed as limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 7 illustrate.

[0032] This application provides a vacuum pump assembly mounting device (hereinafter referred to as the mounting device), which is capable of mounting a pump assembly, the pump assembly including at least two pump assemblies arranged in a vertical direction; such as Figure 1 As shown, the pump installed at the top is the top pump 7, and the pump installed at the bottom is the bottom pump 8. The installation device of this application can install two pump bodies at the same time.

[0033] Specifically, such as Figures 1 to 2 As shown, the installation device includes a mounting frame 1, rollers 2, a top bracket 3, a bottom bracket 4, a connecting frame 5, an adjusting mechanism 6, and a shock absorber 9. The mounting frame 1 is a rectangular frame structure, providing space for installing the pump unit. The top bracket 3 is connected to the top of the mounting frame 1 for installing a top pump 7. The top bracket 3 is installed at the bottom of the mounting frame 1 for installing a bottom pump 8, and the top bracket 3 and the bottom bracket 4 are vertically spaced. In this application, the cooperation of the top bracket 3, the bottom bracket 4, and the mounting frame 1 ensures a more stable connection between the pump bodies, guaranteeing the structural stability of the pump unit. The bottom of the mounting frame 1 is equipped with rollers 2, which are located at the four right-angled bottoms of the mounting frame 1. This allows the mounting frame 1 to move flexibly, making it easier for workers to move the pump unit installed on the mounting device. This reduces the difficulty of moving the pump unit and eliminates the need for auxiliary equipment such as forklifts to move the vacuum pump unit, greatly reducing transportation costs, simplifying transportation procedures, and reducing the probability of wear and tear on the pump unit during movement. The shock absorbers 9 are located on the wide side of the mounting frame 1, that is, on the bottom of the left and right sides of the mounting frame 1. Two shock absorbers 9 are provided on each side at intervals to achieve vibration reduction of the mounting device.

[0034] Among them, such as Figures 1 to 2 As shown, the mounting frame 1 includes a top frame 12 and a base frame 13. The top frame 12 is used to mount the top bracket 3. The top bracket 3 is a columnar structure. The length extension direction of the top bracket 3 is parallel to the front-rear direction of the mounting frame 1. There are at least two top brackets 3, which are arranged side by side with parallel spacing. The top frame 12 of the mounting frame 1 is provided with at least three sets of through holes for mounting the top bracket 3. That is, the front end and the rear end of the top frame 12 are each provided with at least three through holes. The through holes in the same front-rear direction at the front end and the rear end form a set of through holes. Each set of through holes is used to mount one top bracket 3. The three sets of through holes can provide three mounting positions for the top bracket 3, so that the two top brackets 3 have at least two sets of mounting distances. This allows the mounting distance between the top brackets 3 to be adjusted to adapt to different specifications of top pumps 7, thereby improving the installation flexibility and applicability of the mounting device.

[0035] like Figures 1 to 2 As shown, the base frame 13 is located at the lower end of the mounting frame 1. The base frame 13 is used to connect the frame 5. The length of the connecting frame 5 extends parallel to the vertical direction. The top of the connecting frame 5 is connected to the base frame 13, and the bottom of the connecting frame 5 is connected to the bottom bracket 4. That is, the connecting frame 5 extends vertically towards the bottom of the mounting frame 1 to install the bottom bracket 4. The connecting frame 5 can lower the setting position of the bottom bracket 4 so that the bottom bracket 4 can support the bottom of the bottom pump 8; wherein, as Figure 2 , Figure 6 As shown, the base frame 13 is provided with at least three sets of fixing holes 11 for installing at least two connecting frames 5; each set of fixing holes 11 includes two fixing holes 11 respectively set at the front end and rear end of the base frame 13 on the same straight line, each set of fixing holes 11 is used to install one connecting frame 5, and the three sets of fixing holes 11 can provide three installation positions for the connecting frame 5, so that the two connecting frames 5 have at least two sets of installation distances, thereby making the installation distance between the connecting frames 5 adjustable to adapt to different specifications of base pumps 8, improving the installation flexibility and applicability of the installation device.

[0036] Of course, each connecting bracket 5 can be connected to the base frame 13 through one fixing hole 11 or two fixing holes 11; there is no limitation here. Figure 5 As shown, regardless of the number of fixing holes 11 required at the connection between a connecting frame 5 and the base frame 13, each is considered as an installation station. At least three installation stations are provided on the base frame 13 on the same side.

[0037] Among them, such as Figures 1 to 2 , Figure 5As shown, the connection between the connecting frame 5 and the bottom support 4 is achieved through an adjustment mechanism 6. The adjustment mechanism 6 is used to adjust the installation height of the bottom support 4 on the connecting frame 5, thereby making it easier to adjust the distance between the bottom pump 8 and the ground. That is, when the pump set needs to be moved, the bottom support 4 can be raised on the connecting frame 5 by adjusting the adjustment mechanism 6. The rollers 2 at the bottom of the bottom pump 8 can be lifted off the ground without adjusting the base of the entire mounting frame 1. This simplifies the adjustment and saves adjustment costs. After adjustment, the rollers 2 of the bottom pump 8 can be prevented from interfering with the movement of the mounting frame 1 during the movement, thus facilitating the flexible and rapid movement of the mounting frame 1. Furthermore, during the movement, by raising the height of the bottom pump 8, the bottom pump 8 and the top pump 7 are connected as one unit, preventing damage to the bellows between the two pumps due to improper operation during the movement.

[0038] Furthermore, in this application, if Figures 1 to 2 As shown, there are two bottom brackets 4. Each bottom bracket 4 has a connecting frame 5 connected to its front and rear ends. Each connecting frame 5 is equipped with an adjustment mechanism 6 at the connection point with the bottom bracket 4. That is, the bottom bracket 4 has adjustment mechanisms 6 in four directions. When the bottom pump 8 is installed on the bottom bracket 4, the front left, front right, rear left, and rear right parts of the bottom pump 8 can be adjusted in height. Any one or more of the above four directions can be adjusted so that the bottom pump 8 can meet different height or tilt requirements, thus improving the adjustment flexibility.

[0039] Based on any of the above embodiments, the adjustment mechanism 6 will be further described; such as Figure 5 As shown, the adjustment mechanism 6 includes a connecting column 61 and a limiting block 62. The connecting column 61 is a columnar structure, and the limiting block 62 is fixedly connected to any end of the connecting column 61. The outer diameter of the limiting block 62 is larger than the outer diameter of the connecting column 61, and the connecting column 61 is provided with external threads. The connecting frame 5 is provided with a limiting hole 52, and the bottom bracket 4 is provided with a connecting hole 42. The limiting hole 52 and the connecting hole 42 are coaxially arranged and their axes are parallel to the vertical direction. The connecting column 61 passes through the limiting hole 52 and the connecting hole 42 to realize the vertical connection between the bottom bracket 4 and the connecting frame 5, so that the bottom bracket 4 and the connecting frame 5 can be stably connected.

[0040] Among them, such as Figures 3 to 5As shown, the connecting hole 42 is provided with an internal thread, which mates with the external thread on the connecting column 61, so that the connecting column 61 is threadedly connected to the bottom bracket 4; the outer diameter of the limiting hole 52 is greater than or equal to the outer diameter of the connecting column 61, so that the connecting column 61 is rotatably connected to the connecting frame 5, that is, the limiting block 62 of the connecting column 61 is located at the upper end, and the outer diameter of the limiting block 62 is greater than the diameter of the limiting hole 52, so that the vertical displacement of the connecting column 61 is restricted under the action of the limiting block 62, thereby allowing the connecting column 61 to rotate around its axis as the center of rotation, but without axial displacement. Therefore, the operator can rotate the connecting column 61 to cause the bottom bracket 4 to move axially along the connecting column 61, thereby changing the vertical installation height of the bottom bracket 4 on the connecting frame 5.

[0041] In this embodiment, the limiting hole 52 is located at the upper end of the connecting hole 42, and the limiting block 62 is located at the upper end of the limiting hole 52, so as to limit the connecting column 61 in the vertical direction.

[0042] In another optional embodiment of this application, the limiting hole 52 can be set on the bottom bracket 4, and the connecting hole 42 can be set on the connecting frame 5, that is, the connecting column 61 is threadedly connected to the connecting frame 5, and the connecting column 61 is rotatably connected to the bottom bracket 4; wherein, the connecting hole 42, the limiting block 62, and the limiting hole 52 are arranged sequentially from top to bottom in the vertical direction.

[0043] Specifically, such as Figure 4 As shown, the connecting frame 5 includes a first limiting plate 53, a connecting vertical plate 55, a connecting side plate 56, and a second limiting plate 54. The first limiting plate 53 and the second limiting plate 54 are arranged parallel to each other and spaced apart. The upper end of the connecting vertical plate 55 is connected to the first limiting plate 53, and the lower end of the connecting vertical plate 55 is connected to the second limiting plate 54. The first limiting plate 53 and the second limiting plate 54 are vertically connected to the same side of the connecting vertical plate 55, and the length extension direction of the connecting vertical plate 55 is parallel to the vertical direction. The connecting side plate 56 is provided as two pieces, which are respectively arranged on the left and right sides of the connecting vertical plate 55. The two connecting side plates 56 are vertically connected to the connecting vertical plate 55, and the length extension direction of the connecting side plate 56 is parallel to the vertical direction. The connecting side plate 56 protrudes on the same side as the first limiting plate 53 and the second limiting plate 54, and the connecting side plate 56, the first limiting plate 53, and the connecting vertical plate 55 are perpendicular to each other.

[0044] Among them, such as Figure 4 , Figure 6As shown, there is a gap between the top of the connecting side plate 56 and the first limiting plate 53, the length of which is greater than the thickness of the base frame 13, so that the connecting frame 5 can be fitted and installed with the base plate; the first limiting plate 53 is provided with a through hole coaxial with the fixing hole 11 on the base plate, so as to allow the same bolt or screw to be inserted, so as to realize the detachable connection between the connecting frame 5 and the base frame 13; wherein, the limiting hole 52 is located on the second limiting plate 54, and the second limiting plate 54 can block and limit the limiting block 62, so as to ensure the limiting connection effect between the connecting column 61 and the connecting frame 5 in the vertical direction.

[0045] Among them, such as Figure 4 , Figure 5 As shown, the bottom of the connecting side plate 56 extends beyond the bottom of the connecting vertical plate 55 to form a rectangular n-shaped installation space. This space is used to accommodate the bottom bracket 4, that is, the left and right width of the bottom bracket 4 is less than the distance between the two connecting side plates 56, which enables the bottom bracket 4 to be stably installed in the connecting frame 5, ensuring the installation stability of the connecting frame 5 and the bottom bracket 4.

[0046] At the same time, such as Figure 3 , Figure 5 , Figure 7 As shown, the bottom bracket 4 includes a supporting horizontal plate 45, which is parallel to the first limiting plate 53. The middle part of the supporting horizontal plate 45 is used to install the bottom pump 8, and the two ends are used to connect with the connecting frame 5. The connecting hole 42 is provided on the supporting horizontal plate 45, and the supporting horizontal plate 45 is provided with a first fastening nut 43. The first fastening nut 43 is fixedly connected to the supporting horizontal plate 45 and is located at the bottom of the supporting horizontal plate 45. The first fastening nut 43 is coaxially arranged with the connecting hole 42, and the internal thread of the first fastening nut 43 is engaged with the external thread of the connecting column 61. The setting of the first fastening nut 43 can reduce the thickness of the supporting horizontal plate 45 while ensuring the thread length required for threaded connection with the connecting column 61, which can effectively save manufacturing costs.

[0047] Furthermore, based on any of the above embodiments, the mounting device can be further extended; such as... Figures 3 to 5As shown, the connecting side plate 56 has an adjustment hole 51 extending beyond the connecting vertical plate 55. The axis of the adjustment hole 51 is perpendicular to the vertical direction, and its length extension direction is parallel to the vertical direction, meaning the adjustment hole 51 penetrates the connecting side plate 56 in the left-right direction. The bottom bracket 4 also has a supporting side plate 46, which is vertically connected to the left and right sides of the supporting horizontal plate 45. The supporting horizontal plate 45 is connected to the middle of the supporting side plate 46. The supporting side plate 46 is parallel to the connecting side plate 56. The supporting side plate 46 has a mounting hole 41 extending beyond the upper end of the supporting plate. The mounting hole 41 penetrates the supporting side plate 46 in the left-right direction and is a standard circular hole structure. The extension length of the adjustment hole 51 is greater than the diameter of the mounting hole 41. The axes of the mounting hole 41 and the adjustment hole 51 can overlap to allow the same connector 63 to be inserted, thus achieving a stable connection and guiding function between the connecting frame 5 and the bottom bracket 4. Figure 5 As shown, when the operator adjusts the connecting column 61, under the action of the connecting piece 63 and the adjusting hole 51, the bottom support 4 can move along the length direction of the adjusting hole 51, ensuring that the displacement of the bottom support 4 is always in the vertical direction, ensuring the stability of the movement of the bottom support 4, and thus ensuring the stability of the bottom pump 8 during adjustment.

[0048] Among them, such as Figure 5 , Figure 7 As shown, the connector 63 includes a limiting part and a connecting part. The connecting part has a columnar structure, and the limiting part has a cap-shaped structure. The limiting part is connected to any end of the connecting part. The outer diameter of the limiting part is larger than the outer diameter of the connecting part and the mounting hole 41. The limiting part can limit the connection between the connector 63 and the connecting frame 5. The limiting direction is the axial direction of the connector 63. The connecting part is threadedly connected to the first fastening nut 43 to realize the detachable connection between the connecting frame 5 and the bottom bracket 4. Figure 5 , Figure 7 As shown, a second fastening nut 44 is provided at the end of the support side plate 46 away from the connecting side plate 56. The second fastening nut 44 is coaxially arranged with the mounting hole 41, and the internal thread in the second fastening nut 44 is engaged with the external thread of the connector 63. The setting of the second fastening nut 44 can reduce the thickness of the support side plate 46 while ensuring the thread length required for threaded connection with the connector 63, which can effectively save manufacturing costs.

[0049] In this embodiment, the distance between the two parallel support side plates 46 is less than the distance between the two connecting side plates 56, so that the outer side of the support side plate 46 is in contact with the inner side of the connecting side plate 56, thereby increasing the contact area between the connecting frame 5 and the bottom support 4 in the vertical direction, thus increasing the connection stability and relative displacement stability between the bottom support 4 and the connecting frame 5; and the outer side of the two support plates is in contact with the inner side of the two support side plates 46, which can play a certain role in stabilizing and guiding.

[0050] Furthermore, such as Figure 7 As shown, a reinforcing vertical plate 47 is provided between the supporting side plates 46. The reinforcing vertical plate 47 is parallel to the connecting vertical plate 55 and is located at the bottom of the connecting vertical plate 55. It can increase the structural strength of the bottom bracket 4 and ensure the stability of the connection between the bottom bracket 4 and the connecting frame 5. The reinforcing vertical plate 47 is located at the rear end of the supporting side plates 46 so that the front ends of the two supporting side plates 46 are open, so that the user can rotate the connecting column 61 by rotating the limiting block 62.

[0051] In this application, the limiting block 62 can be configured as either an internal hexagonal bolt or an external hexagonal bolt. In actual use, rotating the limiting block 62 with an external tool will rotate the connecting column 61, which in turn drives the bottom bracket 4 to move up and down. Thus, the height of the bottom pump 8 can be adjusted with a simple structure without incurring excessive costs. It has the advantages of simple structure, easy operation, and low cost. Furthermore, the bottom of the bottom pump 8 can be height adjusted at all four positions, which increases the adjustment flexibility and allows the bottom pump 8 to tilt forward, backward, left, and right, providing the advantage of local fine-tuning and improving adjustment sensitivity and flexibility.

[0052] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0053] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
