[0002] At present, large-span steel structures are widely used in the field of construction engineering due to their structural advantages and beautiful shapes. However, the design position of large-span structures is usually located in the middle of the building plane. During installation, due to the limitation of the construction site, it is often impossible to use lifting machinery or the lifting machinery cannot meet the lifting requirements. At this time, it is necessary to use a steel structure sliding device to install the large-span steel structure. Most sliding devices in the project use sliders with friction-reducing materials as sliding devices. The structure is simple and reduces the friction to a certain extent. During the sliding process, the dynamic friction is mainly overcome. However, large-span steel structures are generally heavy. Even if friction-reducing materials are used, the required thrust force is still large, resulting in the existing steel structure sliding devices. There are problems such as large sliding wear of the guide rails, low sliding efficiency, inability to reuse, and high construction costs. In addition, during the sliding process of large-span steel structures, due to the influence of installation errors, temperature shrinkage, force system conversion and other factors at each support point, the contact surface between the slider and the support point is not firmly attached, temporary adjustment is difficult, and the assemblability of the entire sliding device is poor.

[0056] Embodiment 2

[0057] Based on the above-mentioned first embodiment, a construction method is disclosed.

[0058] The first improvement scheme of the present invention is: in order to solve the problem of large wear of the slider and low sliding efficiency during traction and sliding, the movement of the slider assembly is creatively improved. The present invention creatively designs a speed-limiting pulley assembly 5 under the slider bottom plate 6, that is, a high-load-bearing pulley hub 19 is installed under the slider bottom plate 6. In order to prevent the pulley hub 19 from rotating too fast during traction and sliding, a one-way centrifugal speed limiter is creatively designed on the pulley hub 19, that is, a centrifugal control assembly 21. When the speed of the pulley hub 19 reaches the threshold set by the centrifugal control assembly 21, the system immediately responds and triggers the friction block 23. The friction block 23 is made of high-friction material and is in friction contact with the pulley friction surface 25 to achieve a deceleration effect. The faster the pulley 18 rotates, the greater the centrifugal force, the greater the friction between the friction block 23 and the pulley friction surface 25, and the more obvious the deceleration effect.

[0059] The second improvement of the present invention is: in order to solve the problem that the contact surface between the inner base 32 of the slider and the support surface 10 of the slider is not firmly attached and temporary adjustment is difficult during the sliding process of the large-span steel structure, the support of the slider assembly is creatively improved. The present invention creatively designs a height hydraulic adjustment assembly 8 inside the inner base 32 of the slider to adjust the height of the support surface 10 of the slider, and arranges a height hydraulic adjustment assembly 8 on both sides of the hydraulic device to fix the height of the support surface 10 of the slider after adjustment.

[0060] The present invention creatively designs inclined plates around the top of the slider base 4 and designs four groups of angle hydraulic adjustment components 7 to achieve angle adjustment of the slider support surface 10, and sets height hydraulic adjustment components 8 on both sides of the hydraulic device to fix the height of the slider support surface 10 after adjustment. The two groups of angle hydraulic adjustment components 7 and the height hydraulic adjustment components 8 cooperate with each other to achieve arbitrary height and angle adjustment of the slider support surface 10 within a certain range, which meets the sliding bearing requirements of large-span steel structures.

[0061] The third improvement scheme of the present invention is: in order to solve the problems of poor versatility of the guide rail 2 and complicated installation of the limit block 9 during the sliding process of the large-span steel structure, the sliding guide rail 2 is creatively improved. Based on the idea of ​​structural assembly, the present invention creatively performs assembly-type splitting on the guide rail 2. The guide rail 2 can be assembled on site through universal nodes according to the sliding characteristics of the actual project. The limit block 9 is assembled on the upper part of the guide rail 2 through the universal node, which can realize rapid installation before sliding construction and rapid disassembly after sliding is completed. The assembly-type assembly design can be applied to projects with different sliding characteristics.

[0062] Embodiment 3

The bottom end of the support shell 34 is rotatably connected to the first connecting seat 35 through a connecting shaft 43. The bottom of the first connecting seat 35 is fixed to the slider base 4 or the slider oblique base 30. Specifically, the connecting shaft 43 can be located inside the bottom end of the support shell 34 and fixed, so that the first connecting seat 35 is located outside the bottom end of the support shell 34 and is rotatably connected to the connecting shaft 43. The top of the support shell 34 is slidably connected to the adjustment plate 36. The top of the adjustment plate 36 is rotatably connected to the second connecting seat 37. The top of the second connecting seat 37 is fixed to the slider support surface 10, so that the slider support surface 10 can be adjusted parallel or tilted.

[0064] An adjusting drive motor 38 is fixed inside the top of the support shell 34, and an adjusting threaded rod 39 is connected to the output end of the adjusting drive motor 38. The outer side of the top of the adjusting threaded rod 39 is threadedly connected to the adjusting plate 36, so that the rotation of the adjusting threaded rod 39 drives the adjusting plate 36 to extend and retract by sliding inside the support shell 34. Stop plates 41 are provided at the top of the support shell 34 and at both ends of the adjusting plate 36. A fastening bolt 42 is slidably connected inside the stop plate 41, and the bottom end of the fastening bolt 42 is threadedly connected to the support shell 34, so that the stop plate 41 can be adjusted to rotate around the fastening bolt 42 at the top of the support shell 34 through the rotation of the fastening bolt 42. The stop plate 41 is slidably connected to the adjusting plate 36, so that the rotation of the stop plate 41 can enter the inside of the adjusting plate 36, limiting the lifting and lowering of the adjusting plate 36 inside the fastening bolt 42.

[0065] Preferably, stop grooves 40 are evenly distributed inside both ends of the adjustment plate 36, and the stop plate 41 is slidably connected to the adjustment plate 36 through the stop grooves 40. When the stop plate 41 rotates with the fastening bolt 42 as the center and one end of the stop plate 41 enters the inside of the stop groove 40, the adjustment plate 36 cannot be telescopically moved inside the top of the fastening bolt 42.

The top and bottom of the displacement plate 45 close to the supporting shell 34 are fixed with anti-rotation columns 46. The anti-rotation columns 46 and the first connecting seat 35, as well as the anti-rotation columns 46 and the supporting shell 34 are all slidably connected, so that after the anti-rotation columns 46 enter the supporting shell 34 from the inside of the first connecting seat 35, the supporting shell 34 cannot be rotated and adjusted in angle on the inner side of the first connecting seat 35 through the connecting shaft 43.

[0067] Preferably, anti-rotation holes 44 are evenly distributed inside the support shell 34 and on the outside of the connecting shaft 43. The anti-rotation column 46 is slidably connected to the support shell 34 through the anti-rotation holes 44, so that the movement of the anti-rotation column 46 drives the anti-rotation column 46 to move from the inside of the first connecting seat 35 to the inside of the anti-rotation hole 44, thereby limiting the rotation of the support shell 34 on the inner side of the first connecting seat 35.

[0068] The use process of a large-span steel structure sliding device provided by the present invention is as follows: when in use, according to the needs of the use environment, when the hydraulic system cannot be used, the angle hydraulic adjustment component 7 and the height hydraulic adjustment component 8 are replaced, the first connecting seat 35 is fixed to the slider base 4 or the slider inclined base 30 by welding or bolting, and the top of the second connecting seat 37 is fixed to the slider support surface 10, at this time, the adjustment drive motor 38 can be connected to the external power supply through a wire, so that the operation of the adjustment drive motor 38 drives the adjustment threaded rod 39 to rotate, and the rotation of the adjustment threaded rod 39 drives the threadedly connected adjustment plate 36 to telescope inside the support shell 34, thereby adjusting the inclination or height of the slider support surface 10, and at the same time, when the adjustment of the adjustment plate 36 is completed, the stop plate 41 is moved, and the stop plate 41 is rotated with the fastening bolt 42 as the center of the circle, so that one end of the stop plate 41 enters the inner side of the stop groove 40 on the adjustment plate 36, so as to limit the lifting and lowering of the slider inclined base 30 inside the support shell 34;

[0069] When the support shell 34 is rotated on the inner side of the first connecting seat 35 to adjust the angle, the adjusting bolt 47 is rotated at this time, so that the rotation of the adjusting bolt 47 squeezes the sliding displacement plate 45, and the movement of the displacement plate 45 drives the anti-rotation column 46 to move, so that the anti-rotation column 46 moves from the inner side of the first connecting seat 35 into the corresponding anti-rotation hole 44 in the support shell 34, thereby realizing the rotation limitation of the support shell 34 on the inner side of the first connecting seat 35 and improving stability.
