[0055] In order to fully understand the implementation of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present invention is not limited to the specific details familiar to those skilled in the art.

[0056] It should be understood that the purpose of the terms used herein is only to describe specific embodiments and is not intended to limit the present invention, and the singular forms "a", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates otherwise.

[0058] The "parallel" / "perpendicular" and similar expressions used in the present invention include an absolute parallel / perpendicular relationship and a roughly parallel / perpendicular relationship (for example, a relationship that differs from absolute parallel / perpendicular by -5° to +5°), which can have the same effect.

[0059] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0060] Piping, especially the piping of hard pipes, is an important part of the installation of pre-installed equipment such as semiconductor equipment. At present, the piping of most pre-installed equipment requires the final positioning and installation of the special gas pipelines after the pre-installed equipment arrives at the production site; or there is a large gap between the pre-installed piping and the actual position of the equipment pipeline, which affects the installation efficiency and piping accuracy.

[0061] In order to solve the problem that the pipe cannot be accurately arranged before the preset equipment arrives, an embodiment of the utility model provides a low-position pre-positioning device for pipelines. The low position here can be understood as that the pipeline to be positioned is located above the supporting surface at the installation position required by the preset equipment, and the distance from the supporting surface is no more than 1m. The supporting surface in this article can be understood as the upward surface of the supporting structure such as the floor and ground at the production site. The low-position pre-positioning device for pipelines according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0062] like Figures 1 to 5 As shown, a low-position pre-positioning device 300 for pipelines according to an embodiment of the utility model is used to position pipelines (not shown) that extend above a supporting surface but are no more than 1m away from the supporting surface. These pipelines that need to be positioned are usually to be assembled to the low position of a preset device. The low position here can be understood as that the pipeline to be positioned is located above the supporting surface at the installation position required by the preset device and is no more than 1m away from the supporting surface. The positioning of the pipeline mentioned here refers especially to the positioning of the end of the pipeline for connecting the preset device. The low-position pre-positioning device 300 for pipelines may include a position adjustment component 320 and a pipeline positioning component 330.

[0063] The position adjustment assembly may include a base member 321 and a bearing member 322. The base member 321 is suitable for being directly or indirectly mounted on the upper part of the support surface. The bearing member 322 is located above the base member 321. The bearing member 322 is movably connected to the base member 321 in at least one of the first direction D1, the second direction D2, and the height direction D3. Any two of the first direction D1, the second direction D2, and the height direction D3 are perpendicular. For example, the bearing member 322 is movable relative to the base member 321 in the first direction D1, the second direction D2, and the height direction D3. This is conducive to changing the coordinates of the bearing member 322 in the first direction D1, the second direction D2, and the height direction D3 relative to the bearing member 322.

[0064] The pipe positioning assembly 330 is connected to the load bearing member 322. The pipe positioning assembly 330 may include a pipe positioning piece 333. The pipe positioning piece 333 is adapted to be connected to an end of a pipe to be positioned.

[0065] According to the low-position pre-positioning device 300 for pipelines of the utility model, before the preset equipment arrives at the production site, the low-position pre-positioning device 300 for pipelines is installed on the supporting surface by connecting the base member 321 with the supporting surface. The coordinates of the bearing member 322 are adjusted by the position adjustment component 320, thereby adjusting the coordinates of the pipeline positioning component 330 relative to the supporting surface. The pipeline positioning member 333 is connected to the pipeline to be positioned to achieve pre-positioning of the pipeline. By adopting the low-position pre-positioning device 300 for pipelines, the purpose of accurately positioning the pipeline can be achieved before the preset equipment is installed at the production site. In this way, after the preset equipment arrives at the production site, the pipeline can be quickly and accurately docked with the preset equipment, thereby greatly saving time costs, and can effectively shorten the installation and commissioning cycle of the preset equipment, and improve the efficiency and accuracy of the entire installation process.

[0066] See also Figures 1 to 5 For example, the pipeline positioning component 330 includes at least two pipeline positioning members 333. At least two pipeline positioning members 333 are configured such that the relative coordinates between the pipeline positioning members 333 are adapted to the relative coordinates of the positions to be installed of the pipelines to be positioned on the preset equipment. The relative coordinates between the pipeline positioning members 333 can be understood as the coordinates of the pipeline positioning members 333, for example, in the first direction D1, the second direction D2, and the height direction D3 relative to the bearing member 322. The relative coordinates of the installation positions of the pipelines to be positioned on the preset equipment can be understood as the coordinates of the joints for installing the pipelines on the preset equipment, for example, in the first direction D1, the second direction D2, and the height direction D3 relative to the preset equipment. After the pipeline positioning component 330 is adjusted to the coordinates that meet the predetermined requirements, the pipeline positioning component 330 can be used to pre-simulate the structures such as the pipeline installation joints of the preset equipment, so that the pipeline positioning component 330 is used as a reference for piping. Based on this, the positioning of the pipelines after piping is completed is more accurate. After the preset equipment arrives at the site, the bottom pre-positioning device for the pipeline is removed, and then the preset equipment is installed and connected to the completed pipeline. This can greatly improve the installation efficiency, save time and cost, and help the production enterprise enter the commissioning and production stage faster.

[0067] Optionally, the pipeline positioning member 333 is a standard pipeline joint adapted to the pipeline to be positioned. The standard pipeline joint here is a standard part.

[0068] See also Figure 1 and Figure 2In one example, the pipe positioning assembly 330 may include a first mounting member 331. The first mounting member 331 is connected to the bearing member 322. At least part of the at least two pipe positioning members 333 is connected to the first mounting member 331. The first mounting member 331 serves as a carrier for at least part of the pipe positioning members 333 and is connected to the bearing member 322.

[0069] Optionally, the pipe positioning assembly 330 may include a transition connector 335. The transition connector 335 is mounted to the first mounting member 331. A plurality of pipe positioning members 333 are provided. The plurality of pipe positioning members 333 are mounted to the first mounting member 331 through the transition connector 335. The first mounting member 331 is a planar plate. The first mounting member 331 is parallel to or nearly parallel to the height direction D3. The plane on which the plurality of pipe positioning members 333 are located is parallel to a plate surface of the first mounting member 331.

[0070] See also Figures 3 to 5 In another example, the pipe positioning assembly 330 may include a first mounting member 331 and a second mounting member 332. The first mounting member 331 is connected to the bearing member 322. The second mounting member 332 is connected to the first mounting member 331. The second mounting member 332 is arranged to intersect with the first mounting member 331. Some of the at least two pipe positioning members 333 are connected to the first mounting member 331. Another part of the at least two pipe positioning members 333 is connected to the second mounting member 332. Here, the first mounting member 331 is used as a carrier of a part of the pipe positioning members 333 and is mounted to the bearing member 322. At the same time, the second mounting member 332 is used as a carrier of another part of the pipe positioning members 333 and is mounted to the first mounting member 331. For example, the first mounting member 331 is directly mounted to the bearing member 322. The second mounting member 332 is indirectly mounted to the bearing member 322 through the first mounting member 331. By providing the first mounting member 331 and the second mounting member 332 , it is convenient to arrange pipeline positioning members 333 having different directions, distribution positions, etc. on the first mounting member 331 and the second mounting member 332 , respectively.

[0071] Optionally, the orientation of the pipe positioning member 333 connected to the second mounting member 332 is different from the orientation of the pipe positioning member 333 connected to the first mounting member 331 .

[0072] See also Figures 3 to 5 In addition, the pipe positioning assembly 330 may further include a cantilever. The cantilever is connected to the first mounting member 331. The pipe positioning member 333 connected to the first mounting member 331 is located on the cantilever. By providing the cantilever, it is convenient to install the pipe positioning member 333 on the cantilever, thereby facilitating preventing the pipe positioning member 333 from interfering with the first mounting member 331.

[0073] Further, the cantilever is located on one side of the first mounting member 331. The pipe positioning member 333 connected to the second mounting member 332 is located on the other side of the first mounting member 331. This can prevent interference between the cantilever and the pipe positioning member 333 located on the second mounting member 332, and between the pipe positioning member 333 located on the cantilever and the pipe positioning member 333 located on the second mounting member 332.

[0074] Continue reading Figures 3 to 5 For example, the pipe positioning assembly 330 may include at least two cantilevers. The cantilevers are arranged at intervals from each other. If each cantilever is arranged with a cluster of pipe positioning members 333, for example, at least two cantilevers can be used to arrange at least two clusters of pipe positioning members 333. Each cluster of pipe positioning members 333 may be the same or different. The pipe positioning members 333 of different clusters may be the same or different.

[0075] Exemplarily, the first mounting member 331 is configured as a planar plate. The first mounting member 331 is perpendicular to the first direction D1 or the second direction D2. The cantilever extends along a direction intersecting with, for example, perpendicular to, the first mounting member 331.

[0076] See also Figures 1 to 5 In addition, the low-level pre-positioning device 300 for pipelines may further include an auxiliary marking member. The auxiliary marking member is connected to the bearing member 322. The marking end of the auxiliary marking member faces the outer side of the position adjustment component 320 intersecting the height direction D3. In the use state, the auxiliary marking member is used as a reference so that the user can mark the supporting surface and other parts of the production site after the coordinate adjustment of the pipeline positioning component 330 is completed. The mark is usually used to reconfirm whether the coordinates of the pipeline positioning component 330 have changed.

[0077] For example, the low-level pre-positioning device 300 for pipelines may include at least two auxiliary marking members. The at least two auxiliary marking members may include a first auxiliary marking member 351 and a second auxiliary marking member 353. The first marking end 351a of the first auxiliary marking member 351 faces the outside of the first direction D1 of the position adjustment component 320, so as to be suitable for generating a first auxiliary mark on the outside of the first direction D1 of the position adjustment component 320. The second marking end 353a of the second auxiliary marking member 353 faces the outside of the second direction D2 of the position adjustment component 320, so as to be suitable for generating a second auxiliary mark on the outside of the second direction D2 of the position adjustment component 320. The first auxiliary mark and the second auxiliary mark may be virtual marks, light marks, etc. By setting the first auxiliary marking member 351 and the second auxiliary marking member 353, it is helpful to mark the position of the pipeline positioning component 330 more accurately.

[0078] Optionally, the first mounting member 331 is mounted to the bearing member 322 via an intermediate connecting member 323 .

[0079] It is understood that the number of auxiliary marking components can be one, three or more.

[0080] Optionally, the auxiliary marking member can be a laser pen. It is understandable that the first auxiliary marking member 351 is a first laser pen. The first auxiliary mark generated by the first laser pen is a first marking light 351b. The second auxiliary marking member 353 is a second laser pen. The second auxiliary mark generated by the second laser pen is a second marking light 353b.

[0081] Further, the low-level pre-positioning device 300 for pipelines may include a first mounting seat 352 and a second mounting seat 354. The first auxiliary marking member 351 is mounted on the intermediate connecting member 323 via the first mounting seat 352. The second auxiliary marking member 353 is mounted on the intermediate connecting member 323 via the second mounting seat 354.

[0082] See also Figures 1 to 5 In addition, the low-level pre-positioning device 300 for pipelines may further include a fixing assembly 310. The fixing assembly 310 is connected to the base member 321. The fixing assembly 310 is adapted to be connected to the upper portion of the support surface. That is, the position adjustment assembly 320 may be mounted to the upper portion of the support surface by additionally providing the fixing assembly 310.

[0083] Continue reading Figures 1 to 5 For example, the fixing assembly 310 may include a first fixing plate 314. The first fixing plate 314 is connected to the base member 321. The first fixing plate 314 is used to be mounted to a supporting surface by fasteners.

[0084] See also Figures 3 to 5 , further, in some examples, there are vacant parts such as pits on the surface of the support surface. In order to increase the force-bearing area of ​​the bottom of the fixing assembly 310, the fixing assembly 310 may further include a second fixing plate 315. The second fixing plate 315 is fixed to the lower part of the first fixing plate 314. In a plane perpendicular to the height direction D3, the orthographic projection of the first fixing plate 314 partially overlaps the orthographic projection of the second fixing plate 315. The second fixing plate 315 can be understood as a pad.

[0085] In other examples, the fixing assembly 310 may be a metal frame.

[0086] According to an embodiment of the present utility model, the position adjustment assembly 320 may include a first displacement member 324, a first adjustment member 325, a second displacement member 326, a second adjustment member 327, a third displacement member 328 and a third adjustment member 329. The first displacement member 324 is movable relative to the base member 321 in the first direction D1. The first adjustment member 325 is used to be operated to change the position of the first displacement member 324 relative to the base member 321 in the first direction D1. The first adjustment member 325 may include, for example, a screw and a nut. Here, the principle of the screw nut structure is used to convert the rotational motion of the screw into the linear motion of the nut, thereby achieving the purpose of adjusting the movement of the first displacement member 324 in the first direction D1. The second displacement member 326 is movable relative to the base member 321 in the second direction D2. The second adjustment member 327 is used to be operated to change the position of the second displacement member 326 relative to the base member 321 in the second direction D2. The second adjustment member 327 may include, for example, a screw and a nut. Here, the principle of the screw-nut structure is used to convert the rotational motion of the screw into the linear motion of the nut, thereby achieving the purpose of adjusting the second displacement member 326 to move in the second direction D2. The third displacement member 328 is movable in the third direction relative to the base member 321. The third adjustment member 329 is used to be operated to change the position of the third displacement member 328 relative to the base member 321 in the third direction. The third adjustment member 329 may include, for example, a screw and a nut. Here, the principle of the screw-nut structure is used to convert the rotational motion of the screw into the linear motion of the nut, thereby achieving the purpose of adjusting the third displacement member 328 to move in the third direction.

[0087] The method of using one embodiment of the utility model is: first fine-tune the coordinates of the pipeline positioning component 330 through a position adjustment component such as a three-axis adjuster to make it reach the specified position. Then, lay the pipeline and connect the end of the pipeline to the corresponding pipeline positioning member 333 in the corresponding pipeline positioning component 330. Then, turn on the laser pen and mark the positioning point on the object irradiated by the laser pen to facilitate the subsequent correction of the position of the pipeline positioning component 330. When the preset equipment arrives at the site, the entire bottom pre-positioning device is removed and temporarily stored, and then the equipment is installed. At this time, since the piping has been completed in advance, it can be directly connected to the pipeline after the preset equipment is installed, which greatly reduces the installation time of the preset equipment, so that the preset equipment can be installed and debugged in a shorter time, and can be put into use earlier.

[0088] The embodiment of the utility model provides a low-level pre-positioning device 300 for pipelines, which can be equipped with pipeline joints at corresponding positions according to the original factory diagram of the preset equipment in specific applications, so as to achieve pre-plumbing. When the preset equipment actually arrives, it is convenient to quickly and accurately connect these pipelines with the preset equipment, thereby greatly saving time and cost and improving the efficiency and accuracy of the entire installation process.
