Description

Technical Field

[0001] This invention relates to the field of spatial bending and torsion component installation technology, and particularly to a precise positioning device and installation method for spatial bending and torsion components. Background Technology

[0002] With the development of modern building structural technology, people's requirements for the appearance of buildings are constantly changing. Spatial irregular structure technology has created the technical conditions for people to realize architectural structural forms with a modern industrial style. In the process of processing and installing spatial irregular structures, how to accurately assemble the components according to the design dimensions is the key technology to ensure the quality and safety of the building structure.

[0003] Chinese invention patent CN 111775427A discloses a spatial irregular component assembly jig, including a base, a lifting shaft, a lifting rod, a bracket, and a positioning seat. The base includes longitudinal beams, transverse beams, and columns. The lifting shaft is slidably connected vertically to and fixed to the corresponding column on the left end of the base. The lifting rod is slidably connected vertically to and fixed to the corresponding column on the right end of the base. The left end of the bracket is rotatably connected to the lifting shaft, and the right end is mounted on the lifting rod. The positioning seat is slidably connected to and fixed to the bracket. The spatial irregular component assembly jig of this invention facilitates transportation and use, has good structural stability, improves the positioning accuracy of the assembly jig, reduces component assembly dimensional errors, and enables the overall assembly of spatial irregular components with large lengths or curvatures, thus improving the quality and efficiency of spatial irregular steel structure installation.

[0004] The aforementioned device is not convenient for adjusting components with different degrees of curvature when supporting them. When the surface of the component is irregular, the existing clamping device can only contact a portion of it. For irregular surfaces, there are points that cannot be contacted, which makes it impossible to accurately position the component, resulting in errors during installation.

[0005] Therefore, it is necessary to provide a precise positioning device and installation method for spatial bending and torsion components to solve the above-mentioned technical problems. Summary of the Invention

[0015] As a further embodiment of the present invention: the clamping member includes a clamping frame disposed on one side of the L-shaped fixing plate, the clamping frame having two opposing first racks disposed inside, a rotating gear meshing between the two first racks, the rotating gear being rotatably connected to the clamping frame, a fourth telescopic rod and a second spring being fixedly connected between the first racks and the clamping frame, the second spring being sleeved on the outside of the fourth telescopic rod, a clamping head being hinged to one end of each of the two first racks, an adjusting threaded rod being rotatably connected to one end of the clamping frame, the adjusting threaded rod passing through the L-shaped fixing plate and being threadedly connected to the L-shaped fixing plate, and a third telescopic rod being fixedly connected between the L-shaped fixing plate and the clamping frame.

[0016] As a further embodiment of the present invention: the support member includes a contact base plate disposed at the bottom of the support frame, a plurality of third threaded rods are fixedly connected to the top of the contact base plate, a third threaded cylinder is sleeved on the outer side of each of the plurality of third threaded rods, the outer side of each of the plurality of third threaded cylinders is rotatably connected to the bottom of the support frame, a transmission gear is fixedly connected to the outer side of each of the plurality of third threaded cylinders, and an internal gear ring is rotatably connected to the bottom of the support frame, the internal gear ring meshing with the plurality of transmission gears.

[0017] As a further embodiment of the present invention: a limiting frame is fixedly connected to the top of the supporting frame, and multiple slots are provided on the top of the limiting frame. A positioning plate is fixedly connected to the outer side of the rotating ring, and an insert plate passes through the top of the positioning plate. The insert plate is slidably connected to the positioning plate, and the bottom of the insert plate is adapted to the slots provided in the limiting frame.

[0018] The installation method for spatial bending and torsion members includes the following steps:

[0019] S1. First, the component is lifted by a crane, and then the placement of multiple support frames is adjusted according to the shape of the component;

[0020] S2. After the multiple support frames are in place, the support components are used to stabilize the support frames on the ground.

[0021] S3. Adjust the height of the lifting plate using the adjusting mechanism so that the supporting base plate supports the bottom of the component.

[0022] S4. The components are clamped and fixed by the clamping parts set on both sides of the support base plate to ensure that the components can be installed stably.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. Move the support frame by using the casters at the bottom of the support frame. When it moves to the designated position, activate the support components to stabilize the support frame. Then, adjust the height of the lifting plate by adjusting the adjustment components, so that the support base plate supports the bottom of the component and the component is fixed by the clamping components.

[0025] 2. By rotating the rotating ring, the position of the other support frame is adjusted through the second threaded cylinder and the second threaded rod between the first connecting plate and the second connecting plate. When it is necessary to adjust the distance between the other support frame and the former, the second threaded cylinder is rotated to move the second threaded rod connected by the thread inside the second threaded cylinder, thereby adjusting the distance between the first connecting plate and the second connecting plate.

[0026] 3. By pushing the rotating cylinder, the positioning rod inside the rotating cylinder slides out from one of the positioning discs. The positioning rod drives one of the positioning discs to rotate, thereby raising one of the lifting plates. This, in turn, supports the hinge plate between the base plate and the lifting plate to rotate, so that it fits against the bottom of the inclined component and supports the bottom of the component.

[0027] 4. By rotating the adjusting threaded rod, the adjusting threaded rod is limited by the third telescopic rod, pushing the clamping frame to move horizontally. This causes the clamping heads at the front of the two first racks inside the clamping frame to contact the surface of the component. Due to the irregularity of the component surface, once one of the clamping heads contacts the component surface, as the clamping frame continues to move, one of the first racks cannot move. At this time, the other first rack continues to move, causing the clamping head to further contact the surface of the component, thereby achieving the function of clamping and positioning the component.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 10As shown, based on the above-mentioned ideas, the present invention provides the following technical solution: a precise positioning device for the installation of spatial bending and torsion components, comprising the following embodiments:

[0042] Example 1: Includes:

[0043] Multiple support frames 1, each of which is rotatably fitted with a rotating ring 7 on its outer side. A connecting piece is provided between the rotating ring 7 and one side of the support frame 1 for adjusting the position according to the components.

[0044] Multiple support frames 1 are rotatably connected to the top of a rotating support seat 2. The top two sides of the rotating support seat 2 are provided with lifting plates 3. Adjusting components for adjusting the height of the lifting plates 3 are provided between the rotating support seat 2 and the two lifting plates 3. A support base plate 5 is provided between the two lifting plates 3. A hinge plate 501 is hinged between the support base plate 5 and the two lifting plates 3. L-shaped fixing plates 502 are fixedly connected to both sides of the support base plate 5. Clamping components for fixing the components are provided on the outer side of the L-shaped fixing plates 502.

[0045] Multiple casters 901 for movement are installed at the bottom of multiple support frames 1, and support components for locking the support frames 1 are provided at the bottom of the support frames 1.

[0046] In practice, since spatial bending and twisting components are often curved, they need to be fixed after being lifted to ensure accurate positioning during installation and avoid deviations caused by shaking. Therefore, the placement of multiple support frames 1 is adjusted according to the needs of the component installation position. The support frames 1 are moved by the universal wheels 901 at the bottom. When they are moved to the designated position, the support components are activated to keep the support frames 1 stable. The height of the lifting plate 3 is then adjusted by the adjustment components, so that the support base plate 5 supports the bottom of the component and the component is fixed by the clamping components.

[0047] like Figure 2 and Figure 10 As shown, in this embodiment: the connector includes a first connecting plate 701 rotatably connected to the outside of the rotating ring 7 via a shaft pin, a second connecting plate 702 is provided at one end of the first connecting plate 701, the second connecting plate 702 is fixedly connected to the outside of another support frame 1, a fifth telescopic rod 705 is fixedly connected between the first connecting plate 701 and the second connecting plate 702, a second threaded cylinder 703 is rotatably connected to one side of the first connecting plate 701, a second threaded rod 704 is threadedly connected inside the second threaded cylinder 703, and the second threaded rod 704 is fixedly connected to the second connecting plate 702.

[0048] In practice, when it is necessary to adjust the position of another support frame 1, the rotating ring 7 is rotated so that the rotating ring 7 adjusts the position of the other support frame 1 through the second threaded cylinder 703 and the second threaded rod 704 between the first connecting plate 701 and the second connecting plate 702. When it is necessary to adjust the distance between the other support frame 1 and the former, the second threaded cylinder 703 is rotated so that the second threaded rod 704 threaded inside the second threaded cylinder 703 is moved, thereby adjusting the distance between the first connecting plate 701 and the second connecting plate 702.

[0049] like Figure 2 and Figure 9 As shown, in this embodiment: a limiting frame 707 is fixedly connected to the top of the support frame 1. The limiting frame 707 has multiple slots on its top. A positioning plate 706 is fixedly connected to the outside of the rotating ring 7. An insert plate 708 passes through the top of the positioning plate 706. The insert plate 708 is slidably connected to the positioning plate 706. The bottom of the insert plate 708 is adapted to the slots opened in the limiting frame 707.

[0050] In practice, to ensure that the position of the rotating ring 7 remains stable after it rotates, a positioning plate 706 is fixedly connected to the top of the rotating ring 7. The insert plate 708 is pulled to rotate the rotating ring 7. After the rotating ring 7 has rotated, the insert plate 708 is lowered so that it is inserted into the slot opened on the limiting frame 707, thus ensuring that the rotating ring 7 can be stable.

[0051] like Figure 2 and Figure 10 As shown in Embodiment 2: A worm gear 201 is fixedly connected to the outer side of the rotating support base 2. A worm 202 is meshed with the outer side of the worm gear 201. A support plate 204 is rotatably connected to the outer side of the worm 202. The support plate 204 is fixedly connected to the inside of the support frame 1. A rotating handle 205 is provided at the top of the support frame 1. The rotating handle 205 passes through the top of the support frame 1 and is rotatably connected to the support frame 1. A first bevel gear 203 is fixedly connected to the outer side of both the rotating handle 205 and the worm 202. The two first bevel gears 203 mesh with each other.

[0052] In practice, by rotating the handle 205, the first bevel gear 203, which is fixedly connected, is rotated. Since the first bevel gear 203 on the outside of the worm 202 and the first bevel gear 203 on the handle 205 mesh with each other, the worm 202 is rotated. The worm 202 drives the meshing worm wheel 201 to rotate, and the worm wheel 201 drives the fixedly connected rotating support seat 2 to rotate, thereby adjusting the angle of the support base plate 5 between the two lifting plates 3, fitting together according to the components, and maintaining stable support for the components.

[0053] In this embodiment: the adjusting component includes a first threaded cylinder 301 rotatably connected to the top of the rotating support 2, a first threaded rod 302 threadedly connected inside the first threaded cylinder 301, and a first telescopic rod 303 fixedly connected between the lifting plate 3 and the rotating support 2.

[0054] Two first threaded cylinders 301 are fixedly connected to the outer sides of two second bevel gears 407. Two second bevel gears 407 are meshed with third bevel gears 408 on the outer sides of two third bevel gears 408. Two transmission rods 401 are fixedly connected to the outer sides of two transmission rods 401. Support plates are rotatably connected to the outer sides of transmission rods 401. Support plates are fixedly connected to rotating support seats 2. Positioning discs 404 are fixedly connected to opposite ends of two transmission rods 401. Rotating cylinders 402 are sleeved on the outer sides of two positioning discs 404. Positioning rods 403 are fixedly connected to both ends inside the rotating cylinders 402. Positioning grooves are opened on the outer sides of two positioning discs 404. Positioning rods 403 extend into the positioning grooves. A second telescopic rod 405 is rotatably connected between the positioning discs 404 and one end inside the rotating cylinders 402. A first spring 406 is sleeved on the outer side of the second telescopic rod 405.

[0055] In practice, when it is necessary to adjust the height of the support base plate 5, the rotating cylinder 402 is rotated, and the positioning rod 403 set inside the rotating cylinder 402 drives the positioning disk 404 on the two transmission rods 401 to rotate. The positioning disk 404 drives the transmission rod 401 that is fixedly connected, and the transmission rod 401 drives the third bevel gear 408 on the outside to rotate. The third bevel gear 408 drives the meshing second bevel gear 407, and then the second bevel gear 407 drives the first threaded cylinder 301 that is fixedly connected to rotate. Since the first threaded rod 302 is fixedly connected to the lifting plate 3, and the first telescopic rod 303 is fixedly connected between the lifting plate 3 and the rotating support seat 2, the rotation of the first threaded cylinder 301 will push the first threaded rod 302 to rise. The two lifting plates 3 rise synchronously, so that the support base plate 5 can support the components with flat bottoms.

[0056] When the bottom of the component is inclined, by pushing the rotating cylinder 402, the positioning rod 403 inside the rotating cylinder 402 slides out from one of the positioning disks 404. The positioning rod 403 drives one of the positioning disks 404 to rotate, thereby causing one of the lifting plates 3 to rise. This supports the hinge plate 501 between the base plate 5 and the lifting plate 3 to rotate, so that it fits against the inclined bottom of the component and supports the bottom of the component.

[0057] In this embodiment: the clamping member includes a clamping frame 601 disposed on one side of the L-shaped fixing plate 502. The clamping frame 601 has two opposing first racks 604 disposed inside. A rotating gear 605 meshes between the two first racks 604. The rotating gear 605 is rotatably connected to the clamping frame 601. A fourth telescopic rod 606 and a second spring 607 are fixedly connected between the first racks 604 and the clamping frame 601. The second spring 607 is sleeved on the outside of the fourth telescopic rod 606. A clamping head 608 is hinged to one end of each of the two first racks 604. An adjusting threaded rod 603 is rotatably connected to one end of the clamping frame 601. The adjusting threaded rod 603 passes through the L-shaped fixing plate 502 and is threadedly connected to the L-shaped fixing plate 502. A third telescopic rod 602 is fixedly connected between the L-shaped fixing plate 502 and the clamping frame 601.

[0058] In practice, when it is necessary to install and position the component, by rotating the adjusting threaded rod 603, the adjusting threaded rod 603 is limited by the third telescopic rod 602, pushing the clamping frame 601 to move horizontally, so that the clamping heads 608 at the front of the two first racks 604 inside the clamping frame 601 come into contact with the surface of the component. Since the surface of the component is irregular, when one of the clamping heads 608 comes into contact with the surface of the component, as the clamping frame 601 continues to move, one of the first racks 604 cannot move. At this time, the other first rack 604 continues to move, so that the clamping head 608 comes into further contact with the surface of the component, thereby achieving the function of clamping and positioning the component.

[0059] In this embodiment, the support includes a contact base plate 902 disposed at the bottom of the support frame 1. A plurality of third threaded rods 904 are fixedly connected to the top of the contact base plate 902. A third threaded cylinder 903 is sleeved on the outer side of each of the plurality of third threaded rods 904. The outer side of the plurality of third threaded cylinders 903 is rotatably connected to the bottom of the support frame 1. A transmission gear is fixedly connected to the outer side of each of the plurality of third threaded cylinders 903. An internal gear ring 905 is rotatably connected to the bottom of the support frame 1. The internal gear ring 905 meshes with the plurality of transmission gears.

[0060] In practice, when it is necessary to ensure the stability of the support frame 1, the caster wheel 901 is self-locked. Then, by rotating the internal gear ring 905, the internal gear ring 905 drives multiple meshing transmission gears, causing the third threaded cylinder 903 to rotate. When the third threaded cylinder 903 rotates, it drives the third threaded rod 904 to descend, thereby making the contact base plate 902 contact the ground, ensuring the overall stability of the support frame 1.

[0061] The installation method for spatial bending and torsion members is also provided, including the following steps:

[0062] S1. First, the component is lifted by a crane, and then the placement of multiple support frames 1 is adjusted according to the shape of the component;

[0063] S2. After the multiple support frames 1 are in place, the support frames 1 are stably placed on the ground by the support components;

[0064] S3. Adjust the height of the lifting plate 3 by adjusting the adjustment component so that the support base plate 5 supports the bottom of the component;

[0065] S4. The components are clamped and fixed by the clamping parts set on both sides of the support base plate 5 to ensure that the components can be installed stably.

[0066] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
