Description

Technical Field

[0001] This utility model relates to the technical field of ultra-high speed low vacuum pipeline maglev transportation systems, specifically to a smoothness testing device for ultra-high speed low vacuum pipeline maglev transportation systems. Background Technology

[0002] The ultra-high-speed low-vacuum pipeline maglev transportation system is a transportation system that uses superconducting magnetic levitation technology, low-vacuum pipeline technology and superconducting synchronous linear motor technology to enable superconducting vehicles to run at high speed in a closed pipeline. It requires the laying of steel structure pipelines along the route, with a "U"-shaped tube beam at the bottom and a tube shell at the top. The pipeline is erected at a certain height above the ground and the inside of the pipeline is evacuated to a low vacuum.

[0003] The ultra-high-speed, low-vacuum pipeline maglev transportation system uses prefabricated modular slabs installed on both sides of a U-shaped tube beam. These prefabricated modules serve as the carriers for the magnetic reluctance coils, which are mounted on the modules. The symmetrical magnetic reluctance coils on both sides of the tube beam provide a strong magnetic field for train operation. Currently, the prefabricated modules are available in 6m and 3m sizes, and each module is designed with threaded holes for mounting the magnetic reluctance coils. During construction and installation, a smart total station is used for fine-tuning to ensure that the prefabricated modules are precisely placed in their designed positions.

[0004] Accuracy testing after the prefabricated modular panels are installed is a crucial step in ensuring system smoothness. Existing accuracy testing methods involve repeating the testing process during fine-tuning. However, this method is merely a repetition of the fine-tuning work, requires testing at numerous points, and is time-consuming, thus impacting project progress.

[0005] Therefore, there is an urgent need for a detection device that requires fewer detection points and has a shorter detection time. Summary of the Invention

[0006] The purpose of this invention is to provide a smoothness testing device for ultra-high-speed low-vacuum pipeline maglev transportation systems, so as to at least solve the problems of existing testing devices having many testing points and long testing time.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A ride comfort testing device for an ultra-high speed low vacuum pipeline maglev transportation system includes multiple threaded adapters and a prism frame;

[0009] The threaded adapters are respectively installed in the sleeve threaded holes of the module prefabrication plate;

[0010] The prism frame includes a prism rod, a skeleton, and multiple legs. The prism rod is located at the center of the top of the skeleton, and the legs are respectively located at the bottom of the skeleton and are respectively located in the threaded adapter.

[0011] Furthermore, the threaded adapter includes a cylinder, a cone, and a rotating handle. The cone is located at the bottom of the cylinder with its tip pointing downwards, and the rotating handle is located at the top of the cylinder.

[0012] Furthermore, the outer wall of the threaded adapter is provided with threads, which match the threads of the sleeve threaded hole of the module prefabricated plate.

[0013] Furthermore, the threaded adapter has a straight insertion hole at its top.

[0014] Furthermore, the skeleton is X-shaped and includes two intersecting metal plates.

[0015] Furthermore, the metal plate is a long rectangular parallelepiped structure.

[0016] Furthermore, the prism rod is positioned perpendicular to the skeleton.

[0017] Furthermore, at least four legs are provided, symmetrically arranged at the four corners of the frame.

[0018] Furthermore, the brackets are respectively configured to correspond to the threaded holes of the sleeves on the module prefabricated plate.

[0019] Furthermore, the bracket has a cylindrical structure, and the bracket fits into the straight insertion hole of the threaded adapter.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model provides a smoothness testing device for an ultra-high speed low vacuum pipeline maglev transportation system. By setting threaded adapters and prism frames, the number of measurement points is reduced to one, which greatly reduces the number of points, thereby saving measurement time and significantly improving field efficiency. Moreover, the structure is simple, and the prism can be easily placed in the predetermined position after simple assembly, making it easy to use.

[0022] 2. This utility model achieves a tight fit between the threaded adapter and the precast module by screwing the threaded adapter into the threaded hole of the sleeve. Simultaneously, the prism frame's legs are directly inserted into the threaded adapter, which reduces the connection error between the prism frame and the precast module. Furthermore, this utility model can directly obtain the plane coordinates and elevation of the vertical center of the precast module, thereby reflecting the elevation accuracy of the precast module, simplifying the smoothness calculation process, and optimizing the measurement procedure.

[0023] 3. This utility model uses wear-resistant and corrosion-resistant stainless steel material, which makes the overall weight lighter, easy to carry, and not easily worn after repeated use, thus ensuring measurement accuracy. Attached Figure Description

[0032] Example:

[0033] like Figure 1As shown, this embodiment provides a smoothness testing device for an ultra-high-speed low-vacuum pipeline maglev transportation system, including four threaded adapters 1 and a prism frame 5. The testing device is placed on the module prefabricated plate 7. A total station is used to measure the plane coordinates and elevation of the central prism 6 of the prism frame 5, and then the fine-tuning accuracy of the module prefabricated plate 7 is calculated and the smoothness of the system is verified.

[0034] Specifically, the threaded adapter 1 is respectively installed in the sleeve threaded hole 8 of the module prefabricated plate 7.

[0035] In this embodiment, the threaded adapter 1 includes a cylinder, a cone, and a rotating handle. The cone is integrally disposed at the bottom of the cylinder, with the tip of the cone facing downwards. The diameter of the cylinder is the same as the diameter of the bottom surface of the cone. The rotating handle is disposed at the top of the cylinder.

[0036] The cylindrical outer wall of the threaded adapter 1 is provided with threads, which match the threads of the sleeve threaded hole 8 of the module prefabricated plate 7. The threaded adapter 1 is screwed into the sleeve threaded hole 8 of the module prefabricated plate 7 and tightly engaged with it.

[0037] The top of the cylindrical part of the threaded adapter 1 is provided with a straight insertion hole. The threaded adapter 1 serves as an intermediate part to provide mounting holes for the prism frame 5, making the installation of the prism frame 5 convenient and saving time.

[0038] The rotating handle is used to screw the threaded adapter 1 into the sleeve threaded hole 8 of the module prefabricated plate 7. The rotating handle consists of four cuboids. In other embodiments, the rotating handle may also be of other numbers, and is not limited thereto. The cuboids are all welded to the top of the cylinder of the threaded adapter 1. The four cuboids are evenly spaced apart. One end of each cuboid is set around the straight insertion hole, and the other end extends to the edge away from the cylinder.

[0039] Specifically, the prism frame 5 includes a prism rod 2, a skeleton 3, and four legs 4. The prism rod 2 is located at the center of the top of the skeleton 3, and the legs 4 are located at the bottom of the skeleton 3, and the legs 4 are respectively located in the threaded adapter 1.

[0040] Among them, the skeleton 3 is used to provide stable support for the prism rod 2. The skeleton 3 is designed according to the hole size of the four sleeve threaded holes 8 on the module prefabricated plate 7. The skeleton 3 is X-shaped and includes two intersecting metal plates. The metal plates are long rectangular structures. The skeleton 3 is symmetrically arranged.

[0041] The prism rod 2 is vertically welded and fixed to the frame 3. During measurement, the prism 6 is inserted into the prism rod 2. The prism rod 2 serves as a prism connection adapter, allowing the prism 6 to be quickly inserted into the prism rod 2, making the installation of the prism 6 convenient and saving time. After installation, the prism 6 is located at the vertical center of the module prefabricated plate 7.

[0042] Specifically, the brackets 4 are symmetrically welded and fixed to the four corners of the frame 3, and the brackets 4 are respectively set to correspond to the sleeve threaded holes 8 of the module prefabricated plate 7.

[0043] In this embodiment, the bracket 4 is a cylindrical structure, and the bracket 4 fits into the straight insertion hole of the threaded adapter 1, so that the bracket 4 can be tightly inserted into the straight insertion hole of the threaded adapter 1.

[0044] The bracket 4 serves as a connector between the skeleton 3 and the threaded adapter 1. During installation, the skeleton 3 is inserted into the threaded adapter 1 through the bracket 4, and the bracket 4 is inserted directly into the straight insertion hole of the threaded adapter 1, thereby realizing the installation of the prism frame 5 and the module prefabricated plate 7.

[0045] like Figure 2 As shown, during measurement, the threaded adapter 1 is first screwed into the sleeve threaded hole 8 of the precast module 7, and the bracket 4 of the prism frame 5 is inserted into the threaded adapter 1, thereby forming a tight fit between the prism frame 5 and the precast module 7. Then, the prism 6 is inserted into the prism rod 2, and the plane coordinates and elevation of the prism 6 are observed using a total station. The smoothness of the module system can be obtained through post-processing software.

[0046] In this embodiment, both the threaded adapter 1 and the prism frame 5 are made of wear-resistant and corrosion-resistant stainless steel.

[0047] The usage process in this embodiment is as follows:

[0048] 1. Set up the total station and establish a station;

[0049] 2. Screw the four threaded adapters 1 into the four sleeve threaded holes 8 corresponding to the module prefabrication plate 7 respectively, to provide four straight insertion holes for the prism frame 5;

[0050] 3. Insert the four legs 4 of the prism frame 5 into the corresponding threaded adapter 1 through the straight hole, thereby forming a tight fit between the prism frame 5 and the module prefabrication plate 7.

[0051] 4. Insert prism 6 into prism rod 2 to complete the installation of the device;

[0052] 5. Use a total station to measure the plane coordinates and elevation of prism 6;

[0053] 6. Repeat steps 2 to 5 until one station is completed.
