[0041] The steel arch 10 at least includes a side steel arch 11 and a closing section 12 connected between the side steel arches 11. The embodiment of the utility model provides a steel arch vertical rotation structure. Figure 1 As shown, it includes: a column foot 13 is arranged on the construction surface 00, a rigid hinge 20 is arranged on one side of the column foot 13, and the rigid hinge 20 is connected to the side steel arch 11;

[0042] A rotating tower 30 is provided on the other side of the column foot 13;

[0043] A hydraulic cylinder 40 is provided on the top of the rotating tower 30, and a steel arch conversion system 50 is provided on the side steel arch 11;

[0044] The steel strand 60 is connected between the hydraulic cylinder 40 and the steel arch conversion system 50 .

[0045] It can be understood that in this embodiment, the steel arch 10 is divided into three parts, the side steel arches 11 on both sides and the closing section 13 in the middle. The side steel arches 11 on the left and right sides are vertically rotated to the specified position in turn, and the closing section 12 in the middle is then lifted and closed.

[0046] Specifically, a column foot 13 is provided on the construction surface 00, a rigid twist 20 is provided on one side of the column foot 13, and a rotating tower 30 is provided on the other side. The rigid twist 20 is connected to the side steel arch 11, and at the same time, a hydraulic cylinder 40 provided on the top of the rotating tower 30 is connected to a conversion system 50 provided on the side steel arch 11 through a steel twist 60. The hydraulic cylinder 40 pulls the steel twist 60, so that the side steel arch 11 realizes vertical rotation with the rigid twist 20 as the axis. The steel twist 60 can be selected with a diameter of 15.2, which can bear sufficient tension.

[0047] In the embodiment provided by the utility model, a rigid swivel 20 is provided at the column foot 13 of the side steel arch 11, and the side steel arch 11 is pulled by the hydraulic oil cylinder 40 on the swivel tower 30 to make it rotate vertically. The utility model adopts a centralized fully automatic hydraulic control device, which has a high degree of automation, strong reliability, simple operation, and easy control; reduces the investment in construction auxiliary materials and large mechanical equipment, saves time and labor, improves the efficiency of vertical rotation, and has high technical and economic efficiency; avoids high-altitude operations and ensures construction safety.

[0048] In an optional embodiment provided by the present utility model, referring to Figure 3 As shown, the rigid hinge 20 includes an upper hinge structure 21, a lower hinge structure 22 and a swivel pin 23;

[0049] The upper twist structure 21 is connected to the side steel arch 11, and the lower twist structure 22 is connected to the construction surface 00;

[0050] The swivel pin 23 movably connects the upper swivel hinge structure 21 and the lower swivel hinge structure 22 .

[0051] The rigid hinge 20 is used for the vertical rotation of the side steel arch 11. Specifically, the upper hinge structure 21 is connected to the side steel arch 11, the lower hinge structure 22 is connected to the construction surface 00, and the lower hinge structure 22 is arranged on one side of the column foot 13. During the vertical rotation of the side steel arch 11, the upper hinge structure 21 rotates through the swivel pin 23, and at the same time, the side steel arch 11 is vertically rotated together until the side steel arch 11 falls on the column foot 13, and the vertical rotation is completed.

[0052] In an optional embodiment provided by the present utility model, referring to Figure 4 As shown, the steel arch conversion system 50 includes a swivel pull anchor point 51 and a lifting lug 52;

[0053] The swivel anchor point 51 is arranged at the middle and upper part of the side steel arch 11, and the lifting lug 52 is connected to the swivel anchor point 51;

[0054] One end of the steel strand 60 is connected to the lifting eye 52 .

[0055] It is understandable that the steel arch conversion system 50 is for better connection with the side steel arch 11. Specifically, the steel arch conversion system 50 includes a swivel anchor point 51, which is located in the middle and upper part of the side steel arch 11. A lifting lug 52 is provided on the swivel anchor point 51, so that the tension provided by the hydraulic cylinder 40 can be distributed more evenly, thereby improving the safety of vertical rotation. The lifting lug 52 can rotate with the change of the vertical rotation angle of the side steel arch 11 to ensure that the force is balanced and effective.

[0056] In an optional embodiment provided by the present utility model, referring to Figure 1 and Figure 2 As shown, along the same horizontal direction, a plurality of steel arches 10 and a plurality of rotating towers 30 are arranged at intervals, and the rotating towers 30 are at least located at the ends;

[0057] The heights of the plurality of steel arches 10 are not completely equal. The heights of the rotating towers 30 are not completely equal. The height of the rotating towers 30 near the ends is smaller than the height of the rotating towers 30 near the center.

[0058] A back cable 80 is provided between any adjacent rotating towers 30;

[0059] The back cable 80 is connected to the top of the swivel tower 30 .

[0060] A ground anchor 70 is provided on the side of the rotating tower 30 at the end facing away from the steel arch 10;

[0061] The ground anchor 70 is connected to the top of the swivel tower 30 at the end through a back rope 80 .

[0062] It is understandable that in the same project, there are multiple steel arches 10, and the heights are not completely the same. Therefore, the heights of the rotating towers 30 are not completely equal. Generally speaking, the height of the rotating towers 30 near the ends is less than the height of the rotating towers 30 near the center. The steel arches 10 and the rotating towers 30 are arranged in sequence, and the rotating towers 30 are arranged at the ends to ensure that any side steel arch 11 has a rotating tower 30 for providing vertical cable force.

[0063] Furthermore, the rotating tower 30 includes a tower foundation, lattice bracing, horizontal bracing, horizontal and vertical distribution beams, and vertical rotating beams, etc. The rotating tower 30 is used to provide stability during the vertical rotation process and bear the pressure generated by the steel strands 60 and the hydraulic cylinders 40 during the conversion of the vertical rotation force.

[0064] Furthermore, back cables 80 are provided between adjacent rotating towers 30 to support each other as back tension, and the rotating towers 30 at the ends are back tensioned by ground anchors 70. The ground anchors 70 can provide a sufficiently large vertical rotation reaction force.

[0065] Furthermore, the method of using the steel arch vertical rotation structure is:

[0066] (1) Determine the position of the ground anchor 70 and install the ear plate of the ground anchor 70;

[0067] (2) assembling the steel arches 10 sequentially on the construction surface 00;

[0068] (3) Assembling the arch foot 13 and installing the rigid hinge 20;

[0071] (6) Installing a hydraulic cylinder 40 on the top of the rotating tower 30;

[0072] (7) The steel strand 60 is threaded and pulled, and the hydraulic cylinder 40 is connected to the steel arch conversion system 50.

[0073] (8) Installing the back rope 80;

[0074] (9) Vertically rotate the side steel arch 11 on one side until it is in place;

[0075] (10) Vertically rotate the other side steel arch 11 until it is in place;

[0076] (11) The middle closing section 12 is lifted and installed to complete the closing of the steel arch 10.

[0077] (12) Complete the construction of the remaining steel arches by rotating them vertically one by one.

[0078] In an optional embodiment provided by the present utility model, referring to Figure 5 As shown, at least two ground anchors 70 are provided at either end;

[0079] The two connecting ground anchors 70 intersect with the extension line of the back cable 80 of the rotating tower 30 .

[0080] It is understandable that two ground anchors 70 are provided at the end, and the distance between them is greater than the distance between the connection positions on the rotating tower 30, that is, the extension lines of the back cables 80 intersect, so that the ground anchors 70, the back cables 80 and the rotating tower 30 form a triangular structure, which is more stable.

[0081] In an optional embodiment provided by the utility model, the hydraulic cylinder 40 includes a tower cable cylinder. The hydraulic cylinder 40 includes a 100t cylinder, a 200t cylinder, and a 350t cylinder. The hydraulic cylinder 40 is used to provide a pulling force during the vertical rotation process. The hydraulic cylinder 40 includes at least a compression cylinder, the purpose of which is to provide stability for the rotating tower 30.

[0082] In summary, the steel arch vertical rotation structure provided by the utility model achieves at least the following beneficial effects:

[0083] In the embodiment provided by the utility model, a rigid swivel is set at the column foot of the side steel arch, and the side steel arch is pulled by the hydraulic cylinder on the swivel tower to make it rotate vertically.
