Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, and more specifically, to a cable-stayed bridge cable conduit positioning auxiliary tool. Background Art

[0002] A cable-stayed bridge is a structural system consisting of compression-bearing towers, tension-bearing cables, and a bending-bearing main girder. Due to its unique structural characteristics, it is becoming increasingly common in sea- and river-spanning bridges. The cables are the primary load-bearing components that directly transfer the weight of the main girder and deck to the towers. In concrete cable-stayed bridges, the successful installation of the cables depends heavily on the accurate positioning of the cable guides.

[0003] The positioning of the cable guide tube must be precise, otherwise it will cause large changes in the internal force of the structure and affect the quality of the project. In the existing cable-stayed bridge cable guide tube positioning process, it is usually necessary to use an automatic total station for measurement and positioning. However, the total station can only perform rough positioning. Since the cable guide tube is long and heavy, fine-tuning operations are required after positioning with the total station, so positioning auxiliary tools are needed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a cable-stayed bridge cable conduit positioning auxiliary tool, which has the advantage of more precise operation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable-stayed bridge cable duct positioning auxiliary tool, comprising: a positioning seat, a connecting plate, a connecting tube and a locking plate, the positioning seat being an overall arc-shaped structure, with side ear plates provided on both sides of the positioning seat; the positioning seat is relatively provided with two groups, and the connecting plate is installed on the side of the side ear plate facing the axis of the arc structure; a connecting stud is provided on one side of the connecting plate, a screw hole is provided in the connecting tube, and the connecting stud is fitted and connected in the screw hole; the locking plate is provided on the inner side of the arc structure of the positioning seat, and several groups are evenly provided along the arc structure, and several groups of anti-slip heads are evenly provided on the locking plate.

[0007] As a preferred technical solution of the present invention, the cross section of the card slot is an inverted trapezoidal structure, and the card block is configured as an inverted trapezoidal block structure.

[0008] As an optimal technical solution of the present invention, a positioning cylinder is provided on the side ear plate, and a positioning pin is installed in the positioning cylinder through a threaded structure; a positioning hole is correspondingly provided on the clamping block, and the positioning pin is fitted into the positioning hole.

[0009] As a preferred technical solution of the present invention, the connecting tube is symmetrically provided with thread structures in opposite directions, and the connecting studs installed on the two sets of positioning seats are plugged into the two ends of the connecting tube.

[0010] As a preferred technical solution of the present invention, the anti-slip heads are truncated cone-shaped protrusions, and the anti-slip heads are distributed in a rectangular array on the locking plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the auxiliary tool provided by the present invention can clamp and fix the cable guide tube of the cable-stayed bridge by means of two sets of positioning seats that are closed together.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 4As shown, the utility model provides a cable-stayed bridge cable duct positioning auxiliary tool, including: a positioning seat 1, a connecting plate 2, a connecting tube 3 and a locking plate 4, the positioning seat 1 is an overall arc-shaped structure, and side ear plates 11 are arranged on both sides of the positioning seat 1; the positioning seat 1 is relatively arranged with two groups, and the connecting plate 2 is installed on the side of the side ear plate 11 facing the axis of the arc-shaped structure; a connecting stud 21 is provided on one side of the connecting plate 2, and a screw hole is provided in the connecting tube 3, and the connecting stud 21 is fitted and connected in the screw hole; the locking plate 4 is arranged on the inner side of the arc-shaped structure of the positioning seat 1, and several groups are evenly arranged along the arc-shaped structure, and several groups of anti-slip heads 41 are evenly arranged on the locking plate 4.

[0019] By twisting the connecting tube 3, the degree of retraction of the connecting stud 21 is adjusted, thereby varying the spacing between the two sets of positioning seats 1. The two sets of positioning seats 1 can be clamped onto the exterior of the cable guide tube, and their dimensions can be flexibly adjusted to ensure the degree of clamping depending on the cable guide being fastened. Furthermore, the inner side of the positioning seats 1 connects to the cable guide tube via a locking plate 4, with anti-slip bumps 41 increasing friction between the two to prevent slipping.

[0020] The side ear plate 11 is provided with a clamping plate 12 on the side facing the axis of the arc structure, and a clamping slot 15 is provided in the clamping plate 12; the side of the connecting plate 2 facing away from the connecting stud 21 is provided with a clamping block 22, and the clamping block 22 is fitted into the clamping slot 15. The cross section of the clamping slot 15 is an inverted trapezoidal structure, and the clamping block 22 is provided as an inverted trapezoidal block structure.

[0021] The connecting plate 2 is engaged with the card slot 15 in the card plate 12 through the inverted trapezoidal card block 22, and the card connection between the two is achieved through the inverted trapezoidal interlocking structure; the card block 22 and the card plate 12 can only move axially and cannot deviate.

[0022] The side ear plate 11 is provided with a positioning tube 13 , in which a positioning pin 14 is installed via a threaded structure; the block 22 is correspondingly provided with a positioning hole 23 , in which the positioning pin 14 is fitted.

[0023] The positioning pin 14 is clamped in the positioning hole 23 to clamp the clamping block 22 in the clamping plate 12, thereby preventing the axial deviation and facilitating the stability of the two.

[0024] The connecting tube 3 is symmetrically provided with thread structures in opposite directions, and the connecting studs 21 installed on the two sets of positioning seats 1 are plugged into the two ends of the connecting tube 3 .

[0025] The two ends of the connecting tube 3 are connected to the connecting studs 21 on both sides through opposite thread structures, which can achieve the effect of simultaneously approaching or simultaneously moving away in actual application, making adjustment convenient.

[0026] The anti-slip heads 41 are truncated cone-shaped protrusions, and the anti-slip heads 41 are distributed in a rectangular array on the locking plate 4 .

[0027] The multiple frustum-shaped protrusions come into contact with the cable guide tube, thereby increasing the friction between the two.
