Description

Technical Field

[0001] The utility model belongs to the technical field of deviation rectifying devices, and particularly relates to a deviation rectifying device for a stay cable in a cable duct. Background Art

[0002] During the construction of a cable-stayed bridge, the stay cables need to pass through the cable ducts to achieve connection with the main girder and the cable tower. However, due to the influence of various factors, such as slight deviations during construction, changes in material properties, and long-term effects of the external environment, the stay cables often deviate in the cable ducts. This deviation phenomenon not only hinders the installation of the built-in shock absorber but also has an adverse impact on the structural performance and safety of the bridge.

[0003] At present, the common deviation rectifying methods are to use a chain block for dragging or tools such as crowbars for adjustment. However, these methods have many disadvantages: the operation process is complicated, consuming a lot of manpower and time, resulting in low work efficiency; it is difficult to control the deviation rectifying accuracy and difficult to achieve the ideal effect; and it is easy to damage the cable body during operation, posing a safety hazard for the long-term use of the bridge. Therefore, a deviation rectifying device for a stay cable in a cable duct is proposed. Summary of the Invention

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] The present utility model provides a technical solution, a deviation correction device for a stay cable in a cable duct. Please refer to Figure 1 、 Figure 2 and Figure 3 , including:

[0017] A first clamping member 1 and a second clamping member 2. Fixed screws 3 are installed on both sides inside the first clamping member 1 and the second clamping member 2. Both ends of the fixed screw 3 penetrate through the first clamping member 1 and the second clamping member 2 respectively, and nuts are installed on the outside of the fixed screw 3;

[0018] A top frame 4 is arranged at the upper end of the second clamping member 2. A pushing screw 5 is installed inside the top frame 4 by means of thread fit, and a U-shaped clamping groove 6 is installed at one end of the outside of the pushing screw 5.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3, the U-shaped card slot 6 is rotatably connected to the push screw 5, and the U-shaped card slot 6 is used to push the cable body to move.
