Description

Technical Field

[0001] This invention relates to the field of space frame sphere center coordinate determination technology, specifically to a measurement and positioning auxiliary device and method for determining space frame sphere coordinates. Background Technology

[0002] Space frame structures are widely used in the design of large stadiums due to their superior load-bearing performance. In the conventional installation of space frame spheres, workers often need to hold a prism rod against a point on the surface of the sphere for positioning. The center position of the prism changes with the contact point and the inclination, making it impossible to accurately locate the center of the sphere, and the coordinates of the center point are not accurately calculated. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a measurement and positioning auxiliary device and method for determining the coordinates of a space frame sphere are provided to solve the problem of inaccurate positioning of the center point of the space frame sphere.

[0004] To achieve the above objectives, a measurement and positioning auxiliary device for determining the spherical coordinates of a space frame is provided, comprising: A support plate having a plurality of legs spaced apart along the circumference of the support plate, a level being mounted on the support plate, and an annular groove concentrically arranged on the support plate. A base is disposed above the support plate, and the base is formed with a plurality of support rods, which are slidably disposed in the annular groove; A gantry frame is fixed to the base, and a receiving frame is installed between the two columns of the gantry frame that can be raised and lowered to the ground. A prism, compatible with the total station, is embedded in the receiving frame and positioned on the central axis of the support plate.

[0005] Furthermore, the plurality of the support legs are arranged at equal intervals along the circumference of the support plate.

[0006] Furthermore, the plurality of support rods are arranged at equal intervals along the circumferential direction of the base.

[0007] Furthermore, each of the two columns has a sliding groove formed on its opposite side along the length of the column, and a slider is formed on the opposite sides of the receiving frame. The slider is slidably disposed in the sliding groove, and the column is equipped with a driving mechanism for driving the slider.

[0008] Furthermore, the drive mechanism includes: A rotating shaft is rotatably mounted in the slide groove, and the rotating shaft is coaxially connected to a gear. A rack is laid on the slider, and the gear meshes with the rack.

[0009] Furthermore, the column has a through hole that passes through the sliding groove, and the rotating shaft is rotatably inserted in the through hole. The two ends of the rotating shaft extend to the outside of opposite sides of the column, and the two ends of the rotating shaft are respectively equipped with locking members for pressing against the column to lock the rotating shaft.

[0010] Furthermore, the locking member has a threaded hole, and the two ends of the rotating shaft are respectively formed with external threads. The threaded hole of the locking member is screwed into the end of the rotating shaft.

[0011] Furthermore, the perforation is provided along the width direction of the groove.

[0012] This invention provides a method for measuring and positioning the spherical coordinates of a space frame using a measurement and positioning auxiliary device for determining the spherical coordinates of a space frame, comprising the following steps: Multiple support legs of the support plate are set on top of the net ball to be tested; By observing the level and moving the support plate along the spherical surface of the net frame sphere, the support plate is positioned horizontally so that the central axis of the support plate coincides with the center of the net frame sphere. The height of the receiving frame is raised to adjust the distance between the inner prism of the receiving frame and the sphere, so that the total station can observe the prism; The coordinates of the prism were determined using the total station. Based on the prism coordinates and the distance, the center coordinates of the net frame sphere are calculated. The beneficial effect of this invention is that the measurement and positioning auxiliary device for determining the coordinates of the net frame sphere uses an adjustment device to ensure the support plate is horizontally positioned, thereby aligning the center of the support plate, the prism, and the center of the net frame sphere on the same vertical axis, ensuring plumbness. The center position is determined according to the principle that the geometric center is the center of the sphere. The center coordinates are calculated using a total station reading, thus improving the efficiency of determining the center coordinates of the net frame sphere during installation and resulting in more accurate center coordinates.

[0021] Reference Figures 1 to 5 As shown, the present invention provides a measurement and positioning auxiliary device for determining the spherical coordinates of a space frame, comprising: a support plate 1, a base 2, a gantry 3, and a prism 4.

[0022] In this embodiment, the support plate 1 is disc-shaped. The outer diameter of the support plate is much smaller than the outer diameter of the space frame sphere. The support plate 1 has multiple legs 11. The multiple legs 11 are spaced apart along the circumference of the support plate 1. The multiple legs are of equal height, so when the support plate rests on a horizontal surface, the support plate is correspondingly horizontal. A level 12 is mounted on the support plate 1. During construction, the levelness of the support plate is observed using the level 1.

[0023] In a preferred embodiment, the level is a bubble level. The support plate 1 has an annular groove b. The annular groove b is concentrically arranged with the support plate 1.

[0024] The base 2 is positioned above the support plate 1. In this embodiment, the base is rectangular. The base and the support plate are coaxially arranged. The base 2 has multiple support rods 21. The support rods 21 slide in the annular groove b. The support rods are of equal height. The width of the annular groove is adapted to the outer diameter of the support rods. Multiple support rods can slide simultaneously along the circumferential direction of the annular groove, during which time the base and the support plate are always coaxially arranged.

[0025] The gantry 3 is fixed to the base 2. The gantry includes two columns 31 and a crossbeam. The crossbeam is connected to the top of the two columns 31. A receiving frame 32 is installed between the two columns 31 of the gantry 3 and can be raised and lowered to the ground.

[0026] The prism is a total station prism. Prism 4 is matched with the total station. Prism 4 is embedded in the receiving frame 32. Prism 4 is set on the central axis of the support plate 1.

[0027] The receiving frame is set vertically. The receiving frame can slide along the length of the slide, thereby changing the setting height of the prism.

[0028] In this embodiment, multiple support legs 11 are equally spaced along the circumference of the support plate 1. Multiple support rods 21 are equally spaced along the circumference of the base 2.

[0029] There are four legs. The four legs are arranged in a cross shape. There are also four support rods. The four support rods are arranged in a cross shape. The legs are L-shaped. The support rods are inverted L-shaped.

[0030] Combination Figure 1 and Figure 2 Each of the two uprights 31 has a sliding groove 310 formed on its opposite side. The sliding groove 310 is arranged along the length of the uprights 31. Slider blocks 33 are formed on opposite sides of the receiving frame 32. The sliders 33 slide in the sliding grooves 310. A drive mechanism 5 is installed on the uprights 31. The drive mechanism 5 is used to drive the sliders 33 to adjust the setting height of the prism.

[0031] Combination Figures 1 to 3 As shown, the drive mechanism 5 includes a rotating shaft 51 and a rack 52.

[0032] The rotating shaft 51 is rotatably mounted in the slide groove 310. The rotating shaft 51 is coaxially connected to the gear 54. The rack 52 is laid on the slider 33. The gear 54 meshes with the rack 52.

[0033] In this embodiment, the column 31 has a through hole. The through hole passes through the slide groove 310. The rotating shaft 51 is rotatably inserted into the through hole. The two ends of the rotating shaft 51 extend to the outside of opposite sides of the column 31. The two ends of the rotating shaft 51 are respectively equipped with locking members 53 for pressing against the column 31 to lock the rotating shaft 51.

[0034] The locking member 53 has a threaded hole. Both ends of the rotating shaft 51 have external threads. The threaded hole of the locking member 53 is screwed into the end of the rotating shaft 51.

[0035] The perforation is set along the width direction of the groove 310. A locking element is provided on the pivot of one of the columns. After the height of the prism is adjusted to the correct position, the locking element is rotated. The locking elements at both ends of the pivot press against the column to lock the pivot.

[0036] This invention provides a method for measuring and positioning the spherical coordinates of a space frame using a measurement and positioning auxiliary device for determining the spherical coordinates of a space frame, comprising the following steps: S1. Place multiple legs 11 of the support plate 1 on top of the net frame ball 6 to be tested.

[0037] S2. By observing the level instrument 12 and moving the support plate 1 along the spherical surface of the net frame ball 6, the support plate 1 is set in the horizontal direction so that the central axis of the support plate 1 coincides with the center of the net frame ball 6.

[0038] S3. Raise the height of the receiving frame 32 to adjust the distance between the inner prism 4 and the sphere of the receiving frame 32, so that the total station can observe the prism 4.

[0039] S4. Determine the coordinates C of the prism using a total station.

[0040] S5. Based on the prism coordinates C and the distance, calculate the center coordinates A of the net sphere 6.

[0041] Combination Figure 5 As shown in the figure, after the measuring and positioning auxiliary device for determining the coordinates of the grid sphere of the present invention is temporarily set on the top of the grid sphere 6 and the support plate is leveled, the coordinates A of the center of the grid sphere, the coordinates C of the prism, the coordinates D of the vertex of the grid sphere, the distance a from the center of the support plate to the sphere surface, and the distance l from the center of the prism to the center of the support plate are shown in the figure.

[0042] When the measuring and positioning auxiliary device for determining the coordinates of the grid sphere of the present invention is temporarily set on the top of the grid sphere 6 and the support plate is leveled, the prism, the vertex of the grid sphere, and the center of the grid sphere are on the same vertical axis. Accordingly, the coordinates C of the prism are obtained by measuring with a total station as (x, y, z), the coordinates D of the vertex of the grid sphere are (x, y, z-1), and the coordinates A of the center of the grid sphere are (x, y, z-1-R).

[0043] The measurement and positioning auxiliary device for determining the coordinates of a space frame sphere of the present invention uses an adjustment device to make the support plate horizontal, thereby ensuring that the center of the support plate, the prism, and the center of the space frame sphere are on the same vertical axis, ensuring verticality. The position of the sphere center is determined according to the principle that the geometric center is the center of the sphere. The coordinates of the sphere center are calculated by reading the total station, which improves the efficiency of determining the coordinates of the space frame sphere during the installation process and makes the obtained coordinates of the sphere center more accurate.

[0044] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
