[0012] Preferably, an X-axis guiding sliding groove is opened on the lower inner wall of the support seat. An X-axis sliding block is fixed on the lower surface of the X-axis translation seat. The X-axis sliding block is located in the inner cavity of the X-axis guiding sliding groove and is slidably connected thereto.

[0013] Preferably, a Y-axis cylinder is fixed on the inner wall in the middle of the X-axis translation seat. One end of the Y-axis cylinder is fixedly connected to the side wall of the X-axis translation seat. Y-axis guiding sliding grooves are opened on the side walls at both ends of the X-axis translation seat. Y-axis sliding blocks are fixedly installed on the inner walls on both sides of the X-axis translation seat.

[0022] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0023] Please see Figures 1 to 6 The present invention provides a technical solution: Example 1: A hydraulically adjustable support platform for easy connection of arch ribs, comprising: arch rib unit 1.

[0024] Specifically, adjustment platforms 2 are set on the outer sides of both ends of the arch rib unit 1. The adjustment platforms 2 are installed on the lower side of the arch rib unit 1 by steel structure scaffolding. The arch rib unit 1 passes through the central cavity of the adjustment platform 2. An adjustment component 3 is installed inside the adjustment platform 2 to support the end of the arch rib unit 1. While supporting the arch rib unit 1, the adjustment component 3 can also adjust the end position of the arch rib unit 1. When the adjustment components 3 inside the two adjustment platforms 2 adjust the position of both ends of the arch rib unit 1 in the same direction at the same time, the arch rib unit 1 can only translate (X-axis direction, Y-axis direction or Z-axis direction). When only the adjustment component 3 inside one adjustment platform 2 adjusts the end position of the arch rib unit 1, the arch rib unit 1 will rotate. This gives the adjustment of the position of the arch rib unit 1 a higher degree of freedom and ensures that the two adjacent arch rib units 1 can be more accurately connected. Furthermore, the adjustment component 3 includes a support base 4, an X-axis translation seat 5 that is horizontally slidably disposed on the support base 4, the X-axis translation seat 5 can only slide horizontally along the X-axis direction, a Y-axis translation seat 6 that is horizontally slidably disposed on the X-axis translation seat 5, the Y-axis translation seat 6 can only slide horizontally in the Y-axis direction, and a Z-axis lifting seat 7 that is vertically slidably disposed above the Y-axis translation seat 6, the Z-axis lifting seat 7 can only move up and down in the Z-axis direction; Secondly, a hollow spherical shell 71 is fixed in the middle of the Z-axis lifting seat 7. An opening is provided on the upper side of the hollow spherical shell 71, and a rotating connecting ball 8 adapted to the hollow spherical shell 71 is rotatably mounted inside the opening. The rotating connecting ball 8 can rotate at any angle inside the hollow spherical shell 71. A T-shaped connecting block 81 is fixed on the upper surface of the rotating connecting ball 8, and the T-shaped connecting block 81 is fixedly installed on the lower surface of the arch rib unit 1 by bolts. The T-shaped connecting block 81 serves two purposes: firstly, to connect the rotating connecting ball 8 and the arch rib unit 1; secondly, it can limit the rotation angle of the rotating connecting ball 8. Figure 4 As shown, the cooperation between the rotating connecting ball 8 and the hollow spherical shell 71 can be used to rotate and mount the end of the arch rib unit 1 above the Y-axis translation seat 6. Therefore, when the Y-axis translation seat 6 moves, it can drive the end of the arch rib unit 1 to move accordingly. In addition, the end of the arch rib unit 1 can also rotate around the center of the rotating connecting ball 8 at a certain angle to ensure that the angle of the arch rib unit 1 itself can be adjusted to a certain extent.

[0025] To prevent the plane containing the arch rib unit 1 from tilting, this application further includes anti-deviation columns 9 fixedly installed at both ends of the upper surface of the Z-axis lifting seat 7. An expansion joint 91 is provided at the upper end of the anti-deviation column 9, and a clamping block 92 is provided at the upper end of the expansion joint 91. The end of the clamping block 92 away from the expansion joint 91 is hemispherical. The two clamping blocks 92 respectively abut against the two sides of the end of the arch rib unit 1. Figure 5 and Figure 4 As shown, the anti-deviation column 9 and the clamping top block 92 can be used to further limit the arch rib unit 1 and prevent the arch rib unit 1 from tilting. In other words, when the position of the arch rib unit 1 is adjusted, the plane on which the arch rib unit 1 is located always remains vertical, thereby reducing the difficulty of docking between two adjacent arch rib units 1.

[0026] To achieve clamping and positioning of the arch rib unit 1, this application also includes a fastening knob 921 on the outside of the telescopic joint 91. An adjusting screw is fixedly installed in the middle of the fastening knob 921. One end of the adjusting screw passes through the telescopic joint 91 through a thread and is fixedly connected to the clamping top block 92. The operator can adjust the distance between the two clamping top blocks 92 by rotating the fastening knob 921, thereby ensuring that the two clamping top blocks 92 can clamp and position both sides of the arch rib unit 1. In addition, after the arch rib unit 1 is connected, by loosening the fastening knob 921 to make the two clamping top blocks 92 move away from each other, it is also convenient to separate the entire device from the arch rib unit 1.

[0027] In order to adjust the position of the telescopic joint 91, this application also has a guide post 911 fixed at the lower end of the telescopic joint 91, and the lower end of the guide post 911 is movably inserted into the interior of the anti-deviation column 9. The guide post 911 is used to guide the direction of relative sliding between the telescopic joint 91 and the anti-deviation column 9, that is, the telescopic joint 91 can only move closer to or further away from the anti-deviation column 9. A double-headed stud 912 is provided between the anti-deviation column 9 and the telescopic joint 91 to drive the telescopic joint 91 to rise and fall. The double-headed stud 912 is provided to adjust the distance between the telescopic joint 91 and the anti-deviation column 9, thereby ensuring the stability of the position of the clamping top block 92.

[0028] To facilitate manual adjustment of the distance between the expansion joint 91 and the anti-deviation column 9, the upper and lower ends of the double-ended stud 912 of this application are threaded into the expansion joint 91 and the anti-deviation column 9, respectively. The double-ended stud 912 and the guide post 911 are kept parallel. The guide post 911 and the double-ended stud 912 cooperate with each other to prevent the expansion joint 91 from rotating around the guide post 911 or around the double-ended stud 912. A polygonal collar 913 is fixedly sleeved in the middle of the double-ended stud 912. The operator can rotate the double-ended stud 912 by turning the polygonal collar 913 with an external tool, thereby controlling the distance between the expansion joint 91 and the anti-deviation column 9. It should be noted that the threads at the upper and lower ends of the double-ended stud 912 of this device are in opposite directions.

[0029] To drive the X-axis translation base 5 to slide, the cross-section of the support base 4 in this application is a "C" shape with an upward opening. The X-axis translation base 5 is a horizontally placed "C" shape. X-axis cylinders 42 are fixedly installed on both inner walls of the support base 4. The movable end of the X-axis cylinder 42 is fixedly connected to the outer wall of the X-axis translation base 5. When the X-axis cylinder 42 works and expands or contracts, it can drive the X-axis translation base 5 to slide horizontally.

[0030] To guide and limit the sliding of the X-axis translation base 5, this application also has an X-axis guide chute 41 opened on the lower inner wall of the support base 4. An X-axis slider 51 is fixed on the lower surface of the X-axis translation base 5. The X-axis slider 51 is located inside the X-axis guide chute 41 and is slidably connected thereto. The cooperation between the X-axis guide chute 41 and the X-axis slider 51 can limit and guide the sliding of the X-axis translation base 5, thereby improving the stability of the movement of the X-axis translation base 5.

[0031] To drive the Y-axis translation base 6 to slide, this application also has a Y-axis cylinder 53 fixedly installed on the middle inner wall of the X-axis translation base 5. One end of the Y-axis cylinder 53 is fixedly connected to the side wall of the Y-axis translation base 6. Y-axis guide chutes 62 are opened on the side walls at both ends of the Y-axis translation base 6. Y-axis sliders 52 are fixedly installed on both inner walls of the X-axis translation base 5. The Y-axis sliders 52 are slidably connected and adapted to the Y-axis guide chutes 62. The Y-axis cylinder 53 is used to drive the Y-axis translation base 6 to slide, and the cooperation between the Y-axis sliders 52 and the Y-axis guide chutes 62 can guide and limit the sliding of the Y-axis translation base 6.

[0032] To drive the Z-axis lifting base 7 to lift and lower, this application also has a Z-axis cylinder 72 arranged between the Z-axis lifting base 7 and the Y-axis translation base 6, and the upper and lower ends of the Z-axis cylinder 72 are respectively fixedly connected to the Z-axis lifting base 7 and the Y-axis translation base 6. Vertical Z-axis guide rods 61 are fixedly installed at the four corners of the Y-axis translation base 6. The Z-axis guide rods 61 pass through the Z-axis lifting base 7 movably, and a limiting platform is fixed at the upper end of the Z-axis guide rods 61. When the Z-axis cylinder 72 works and expands or contracts, it can drive the Z-axis lifting base 7 to lift and lower. The arrangement of the Z-axis guide rods 61 can improve the stability of the Z-axis lifting base 7 when lifting and lowering, and at the same time limit the lifting height of the Z-axis lifting base 7.

[0033] To support the Y-axis translation base 6, the thickness dimensions of the X-axis translation base 5 and the Y-axis translation base 6 in this application are the same. The lower surface of the Y-axis translation base 6 is in contact with the lower inner wall of the support base 4, and a lubricating medium is coated between the Y-axis translation base 6 and the support base 4. The support base 4 can support the Y-axis translation base 6, and the lubricating medium can reduce the friction force when the Y-axis translation base 6 slides horizontally.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
