Description

Technical Field

[0001] This utility model relates to a cable-stayed bridge correction device, belonging to the technical field of correction devices. Background Technology

[0002] During the construction of a cable-stayed bridge, the stay cables need to pass through cable guides to connect with the main girder and towers. However, due to various factors, such as minor deviations during construction, changes in material properties, and the long-term effects of the external environment, these deviations can hinder the installation of built-in shock absorbers.

[0003] Common methods of cable alignment correction include using chain hoists for pulling or using tools such as pry bars for adjustment. However, these methods can easily damage the cables, posing safety hazards for the long-term use of the bridge, and the accuracy of the correction is difficult to control. To address these shortcomings, this invention proposes a cable alignment correction device. Utility Model Content

A straightening device for adjusting the cable-stayed bridge end is fitted onto the top surface of the support frame. The straightening device comprises a first base and a second base that fit together symmetrically, and directional adjustment seats are aligned on the first base and the second base. A screw adjustment mechanism is symmetrically threaded onto the two directional adjustment seats. Two reinforcing tie rods are connected to the front and rear sides of the first base and the second base. The first base and the second base have the same structure.

[0006] A further improvement is that the first base includes an L-shaped base, and a fixed edge is welded to the lower left side of the L-shaped base. Two adjustment slides are spaced apart on the top surface of the L-shaped base. The adjustment slides are arc-shaped. A semi-circular opening is opened in the middle of the right side of the L-shaped base. Multiple pull rod through holes are opened at the front and rear ends of the left side of the L-shaped base.

[0007] A further improvement is that the two adjusting seats include T-shaped seats, and the bottom surface of the T-shaped seats is equipped with multiple bolts and nuts passing through the two adjusting slides. The T-shaped seats also have adjusting threaded holes opened laterally in the middle, and multiple support slide rod through holes are opened laterally on the front and rear sides of the T-shaped seats.

[0008] A further improvement is that the spiral adjustment mechanism includes an adjusting screw that is rotatably fitted onto the adjusting threaded hole, and a rotating seat and a clamping block are provided at the right end of the adjusting screw. A protective pressure pad is fitted in the arc-shaped groove on the left side of the clamping block. The protective pressure pad is made of rubber. Multiple support slide rods are arranged laterally on the left side of the clamping block, which pass through the support slide rod openings in sequence.

[0009] Further improvements are made to the fact that the bridge tower ends, support frames, stay cables, and reinforcing rods are all existing technologies, and their structures will not be described in detail here.

[0010] The beneficial effects of the utility model are:

[0011] This utility model provides a cable-stayed bridge correction device. The device is constructed by combining a first base, a second base, a directional adjustment seat, a screw adjustment mechanism, and a reinforcing tie rod. The first and second bases are designed as separate units, facilitating subsequent assembly during cable correction. The directional adjustment seat allows for precise symmetrical alignment on both bases based on the cable's deviation, ensuring accurate positioning of the screw adjustment mechanism for lateral cable correction. The reinforcing tie rod enhances the tension during correction after the first and second bases are assembled, preventing them from being forced apart. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figure 1-5The present invention provides a schematic diagram of a cable-stayed bridge correction device. The device comprises a bridge tower end 1, on which a support frame 2 is installed. A cable-stayed bridge cable 3, fixed to the bridge tower end 1, passes through the middle of the support frame 2. A correction device 4 for adjusting the cable-stayed bridge cable 3 is fitted onto the top surface of the support frame 2. The correction device 4 includes a symmetrically fitted first base 41 and a second base 42. Alignment seats 43 are aligned on the first base 41 and the second base 42, and spiral adjustment mechanisms 44 are symmetrically threaded onto the two alignment seats 43. Two reinforcing rods 45 are connected to the front and rear sides of the first base 41 and the second base 42. The first base 41 and the second base 42 have the same structure.

[0019] The first base 41 includes an L-shaped base 411, and a fixed edge 412 is welded to the lower end of the left side of the L-shaped base 411. Two adjusting slides 413 are spaced apart on the top surface of the L-shaped base 411. The adjusting slides 413 are arc-shaped. A semi-circular opening 414 is opened in the middle of the right side of the L-shaped base 411. Multiple pull rod through holes 415 are opened at the front and rear ends of the left side of the L-shaped base 411.

[0020] The two adjusting seats 43 include T-shaped seats 431, and the bottom surface of the T-shaped seats 431 is equipped with a plurality of bolts 432 and nuts 433 passing through the two adjusting slides 413. The T-shaped seats 431 are provided with adjusting threaded holes 434 in the middle, and the front and rear sides of the T-shaped seats 431 are provided with a plurality of support slide rod through holes 435 in the front.

[0021] The screw adjustment mechanism 44 includes an adjustment screw 441 rotatably fitted onto the adjustment threaded hole 434.

A protective pressure pad 444 is fitted into the arc-shaped groove on the left side of the clamping block 443. The protective pressure pad 444 is made of rubber. Multiple support slide rods 445 are arranged laterally on the left side of the clamping block 443, which pass through the support slide rod through-hole 435 in sequence.

[0022] Working principle:

[0023] When correcting the deviation of the stay cable 3, the support frame 2 is pre-installed, which facilitates the subsequent assembly of the correction device 4. When installing the correction device 4, firstly, the first base 41 and the second base 42 are symmetrically fixed on the top surface of the support frame 2. A circular opening for the stay cable 3 to pass through is formed by two semi-circular openings 414. First, the directional adjustment seat 43 and the screw adjustment mechanism 44 are pre-assembled. Then, the deviation of the stay cable 3 is checked. The two directional adjustment seats 43 are inserted into the adjustment slide 413 corresponding to the position of the stay cable 3 and locked with nuts 433. Then, the two reinforcing tie rods are passed through the tie rod openings 415 to tighten and reinforce the first base 41 and the second base 42 to enhance the pushing strength. Finally, the deviation of the stay cable 3 is corrected by adjusting one screw adjustment mechanism 44 in the opposite direction to laterally press the cable body of the stay cable 3. After completion, the other screw adjustment mechanism 44 is used to clamp the other side of the cable body of the stay cable 3 to prevent the stay cable 3 from deviating again.
