[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of an auxiliary hydraulic climbing formwork construction arc-shaped guide device for curved tower columns of cable-stayed bridges, comprising a first hollow plate 1, with telescopic plates 3 rotatably connected to the left and right sides of the bottom of the first hollow plate 1, a second hollow plate 4 rotatably connected to the outer side of the telescopic plates 3, a rotating rod 8 rotatably connected to the inner sides of the first hollow plate 1 and the second hollow plate 4, a first gear 7 fixedly connected to the left and right sides of the outer wall of the rotating rod 8, a first bevel gear 9 fixedly connected to the middle of the outer wall of the rotating rod 8, and a second bevel gear 9 rotatably connected to the front side of the inner wall of the first hollow plate 1 and the second hollow plate 4. The device is equipped with a bevel gear 10, which meshes with the first bevel gear 9 for transmission. Second gears 17 are rotatably connected to the left and right sides of the inner walls of the first hollow plate 1 and the second hollow plate 4. These second gears 17 mesh with the first gear 7 for transmission. Multiple second gears 17 extend through the outer sides of the first hollow plate 1 and the second hollow plate 4 and are fixedly connected to a first rotating wheel 5. A first belt 6 is provided on the outer side of the first rotating wheel 5, and multiple first rotating wheels 5 are connected to each other via the first belt 6. A positioning mechanism 2 is provided on the inner side of the first hollow plate 1 for fixing the device.

[0040] Specifically, the relative rotation between the first hollow plate 1 and the second hollow plate 4 can be adjusted by the rotation and extension of the telescopic plate 3. Then, when the second bevel gear 10 rotates, it drives the first bevel gear 9 to rotate through meshing transmission, and at the same time drives the rotating rod 8 connected to it and the first gear 7 on it to rotate together. At this time, the first gear 7 further drives the second gear 17 to rotate through meshing transmission. With the rotation of the second gear 17, the multiple first rotating wheels 5 on the first belt 6 are made to rotate synchronously by the transmission action of the first belt 6.

[0041] Reference Figure 3 , Figure 4 and Figure 5The positioning mechanism 2 includes an electric telescopic rod 201. Multiple electric telescopic rods 201 are fixedly connected to the left and right sides of the inner walls of the first hollow plate 1 and the second hollow plate 4, respectively. A movable plate 202 is fixedly connected to the rear side of the electric telescopic rod 201. Second rotating wheels 203 are rotatably connected to the left and right sides of the outer wall of the movable plate 202. A second belt 204 is provided on the outer side of the second rotating wheel 203. The second rotating wheel 203 is connected to the second belt 204 through transmission. A motor 206 is fixedly connected to the middle of the front side of the movable plate 202. The output end of the motor 206 passes through the movable plate 202 and is fixedly connected to the corresponding second rotating wheel 203. The rear sides of multiple second rotating wheels 203 pass through the first hollow plate 1 and the telescopic plate 3 and are fixedly connected to threaded blocks 205.

[0042] Specifically, after starting the motor 206, its power is transmitted to the second rotating wheel 203 through the second belt 204, causing the second rotating wheel 203 to start rotating. At the same time, it drives the connected threaded block 205 to rotate synchronously. Then, the electric telescopic rod 201 is started to push the moving plate 202 to move. During the rotation of the threaded block 205, the moving plate 202 will move the threaded block 205 out from between the first hollow plate 1 and the second hollow plate 4 until it contacts and fixes the cable-stayed bridge part to be installed, which can quickly install and position the device.

[0043] Reference Figure 2 , Figure 3 and Figure 4 Handles 12 are fixedly connected to the left and right sides of the front end of the outer wall of the first hollow plate 1, and protective sleeves 13 are fixedly connected to the outer side of the handles 12; knobs 11 are rotatably connected to the middle of the front end of the first hollow plate 1 and the second hollow plate 4, and the outer sides of multiple knobs 11 pass through the first hollow plate 1 and the second hollow plate 4 and are fixedly connected to the second bevel gear 10; controller 16 is fixedly connected to the middle of the top end of the second hollow plate 4, and controller 16 is electrically connected to electric telescopic rod 201 and motor 206 respectively;

[0044] Specifically, the handle 12 makes it easy for workers to hold, so as to help them maintain their balance when the device is working or to facilitate the handling of the device when it is dismantled. The protective cover 13 on it can improve the comfort of holding. The corresponding knob 11 can be manually rotated to rotate the corresponding second bevel gear 10. The controller 16 can control the starting and running power between the electric telescopic rod 201 and the motor 206 respectively.

[0045] Reference Figure 1 , Figure 2 and Figure 5Positioning blocks 14 are fixedly connected to the left and right sides of the outer walls of the first hollow plate 1 and the second hollow plate 4, and positioning holes 15 are opened on the outer side of the positioning blocks 14; slots 18 are opened on the left and right sides of the outer walls of the second hollow plate 4, and a manned platform 19 is fixedly connected to the inner side of the slots 18; brackets 20 are fixedly connected to the left and right sides of the rear end of the manned platform 19, and the top of the brackets 20 is fixedly connected to the second hollow plate 4.

[0046] Specifically, by installing threaded parts in the positioning holes 15 on the positioning block 14, the device can be easily installed and fixed. The slot 18 can fix the manned platform 19 inside the second hollow plate 4 so that the staff can work and operate on the device. The bracket 20 can improve the structural strength and stability between the manned platform 19 and the second hollow plate 4.

[0047] Working principle: Before using the device, the rotation and extension of the telescopic plate 3 can adjust the rotation between the first hollow plate 1 and the second hollow plate 4. Then, rotating the second bevel gear 10 can drive the first bevel gear 9 to rotate through meshing transmission, and at the same time drive the rotating rod 8 and its first gear 7 to rotate. At this time, the second gear 17 can be driven to rotate through meshing transmission. As the second gear 17 rotates, it can cooperate with the first belt 6 to drive the multiple first rotating wheels 5 on it to rotate synchronously, so as to improve the synchronization and stability of the device during rotation.

[0048] Furthermore, by starting the motor 206, the second rotating wheel 203 can be driven to rotate through the transmission of the second belt 204, and the threaded block 205 will rotate synchronously with the rotation of the threaded block 205. At this time, the electric telescopic rod 201 is started to push the moving plate 202 to move, so that when the threaded block 205 rotates, it will push out the first hollow plate 1 and the second hollow plate 4, so that it can be fixed with the cable-stayed bridge to be installed, thereby enabling the quick installation and positioning of the device.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
