[0024] Example 1, as Figures 1-4As shown, a novel multi-directional adjustment device for the installation and alignment of steel pipe arch segments includes a support bracket 1. A bottom crossbeam 2, made of rectangular or square tubing, is mounted on the top of the support bracket 1 and connects to a temporary support to transfer the upper load. A limiting vertical support 3, made of I-beam, is fixedly connected to the top of the bottom crossbeam 2. The groove of the I-beam constrains the freedom direction of the support 7; therefore, the width of the support 7 is required to be slightly smaller than the width of the groove of the limiting vertical support 3, with the difference preferably controlled within 1 cm. A diagonal support 4 is fixedly connected to one side of the limiting vertical support 3. The diagonal support 4 reinforces the limiting vertical support 3, improving its stability and strength. The diagonal support 4 is fixedly connected to the top of the bottom crossbeam 2. An inner rib plate 5 is fixedly connected to the side of the limiting vertical support 3 away from the diagonal support 4. The inner rib plate 5 is fixedly connected to the top of the bottom crossbeam 2. The inner rib plate 5 is made of thick steel plate and plays the role of structural reinforcement and limiting the lowest position of the support 7. Therefore, the height of the inner rib plate 5 is required to be slightly greater than the height of the jack 6 body to ensure the placement of the jack 6. An adjustment component is provided on the inner side of the limiting vertical support 3.

[0025] As the skeleton of the device, it is arranged on the top of the support bracket 1, providing a mounting base for the adjustment components, maintaining the stability of the bracket 7 and restricting its degree of freedom.

[0026] The adjustment component is the direct load-bearing component supporting the steel pipe arch segment, and also serves as the installation basis for the control component.

[0027] The top of the adjustment assembly is equipped with a control assembly, which includes a jack 6 located on the top of the bottom crossbeam 2. A support 7 is located on the top of the jack 6. The top of the support 7 has an arc-shaped profile. Multiple reinforcing ribs are provided on both sides of the support 7 to enhance strength. The support 7 is slidably connected to the inner side of the limiting vertical support 3. A main board 8 is fixedly connected to the top of the support 7. A threaded rod 9 is slidably connected inside the main board 8. A positioning rod 10 is slidably connected inside the main board 8. A baffle 11 is fixedly connected to one end of the threaded rod 9. A reinforcing rib 18 is fixedly connected to the end of the threaded rod 9 near the baffle 11. The reinforcing rib 18 is fixedly connected to one side of the baffle 11. The positioning rod 10 is fixedly connected to one side of the baffle 11.

[0028] The control assembly includes a kit 12 rotatably connected to the inside of the main board 8. A handle 13 is fixedly connected to the top of the kit 12. A ratchet 14 is rotatably connected to the inside of the kit 12. A threaded sleeve 15 is fixedly connected to the inside of the ratchet 14. The threaded sleeve 15 is rotatably connected to the inside of the kit 12. The threaded sleeve 15 and the threaded rod 9 are connected in a threaded manner. A limit rod 16 is slidably connected to the inside of the handle 13. A ratchet 17 is rotatably connected to the inner wall of the kit 12. A torsion spring is provided between the ratchet 17 and the kit 12. The torsion spring limits the ratchet 17 so that the ratchet 17 remains on the same vertical center line as the limit rod 16 when it is not under force. The handle 13 is inserted into the top of the ratchet 17.

[0029] In this embodiment, when installing the steel pipe arch, the support bracket 1 is erected, and the bottom crossbeam 2 is placed on top of the support bracket 1, with the bottom crossbeam 2 aligned with the center line of the support bracket 1. The jacks 6 and the adjustment components are installed, and the control components and condition components are combined. The support 7 is placed inside the two side limiting vertical supports 3, thereby connecting the adjustment components with the limiting vertical supports 3. The steel pipe arch segment is hoisted, with one end aligned with the arch foot and limited by a clamp plate, while the other end is placed on top of the support 7. At this time, the jacks 6 on both sides are activated to lift the support 7 until the steel pipe arch inside the support 7 is at the required height. Then, the handles 13 on both sides are pushed to move the baffle 11 to the required position, thus completing the positioning of the steel pipe arch. With the help of the jacks 6, the steel pipe arch can be adjusted with high precision, and the operation is convenient and multi-directional, which can greatly improve the accuracy and efficiency of the steel pipe arch alignment.

[0030] Simultaneously, when the handle 13 is pushed to adjust the position of the baffle 11, the handle 13 will drive the assembly 12 to rotate, thereby causing the ratchet 17 to engage with the ratchet 14. The ratchet 17 limits the ratchet 14, thus allowing the ratchet 14 to rotate. The ratchet 14 engages with the threaded rod 9 through the threaded sleeve 15, thereby causing the threaded rod 9 to drive the baffle 11 to move. At the same time, the positioning rod 10 moves accordingly, limiting the baffle 11 to only be able to slide. After a single push of the handle 13, the limiting rod 16 is pulled upwards, causing the limiting rod 16 to separate from the top of the ratchet 17. At this time, the ratchet 17 loses its limit and can rotate. By pulling the handle 13, the assembly 12 is reset. At this time, the ratchet 17 and the… When the ratchet 14 contacts the ratchet, the ratchet 17 rotates and the torsion spring is stretched. After the kit 12 is reset, the ratchet 17 is located in the gap outside the ratchet 14. The torsion spring contracts and drives the ratchet 17 to reset. At this time, the ratchet 17 and the limit rod 16 are on the same vertical center line. By pressing the handle 13 downward, the handle 13 is inserted into the ratchet 17, so that the ratchet 17 can drive the ratchet 14 to rotate again to adjust the baffle 11. Conversely, it can make the baffle 11 slide in the opposite direction. Thus, by pulling the handle 13 back and forth, the baffle 11 can be moved laterally. This operation method is simple and convenient, and it can make the baffle 11 slide horizontally back and forth, thereby improving the flexibility of adjusting the steel pipe arch.

[0031] How to use: Step 1: Based on the splicing position and elevation of the steel pipe arch segments, erect temporary support scaffold 1.

[0032] Step 2: Place the frame of the device on top of the support bracket 1, aligning the center line with the center line of the support bracket 1.

[0033] Step 3: Place two jacks 6 on the top surface of the bottom crossbeam 2 with the center line of the device as the axis of symmetry.

[0034] Step 4: Install the partial assembly consisting of the adjustment component and the control component onto the inner side of the two limit vertical supports 3.

[0035] Step 5: Reset the control components and the stroke of jack 6, and connect and check the oil circuit connection of jack 6.

[0036] Step 6: Hoist the first steel pipe arch segment, aligning one end with the arch foot and limiting it with a clamp, while placing the other end on top of the support 7.

[0037] Step 7: In conjunction with the measurement, adjust the stroke of jack 6 and the pushing amount of baffle 11 respectively to control the positioning and installation accuracy of the first steel pipe arch segment.

[0038] Step 8: After the first section of the steel pipe arch is positioned and aligned, jacks or sleepers or other supports are set on the temporary support for limiting and fixing.

[0039] Step 9: Release jack 6 to complete the transformation of the force system.

[0040] Step 10: Remove the device longitudinally and disassemble it to prepare for the installation of the next segment.

[0041] Step 11: Repeat steps 1-10 to complete the installation of the subsequent steel pipe arch segments.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
