Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a positioning and driving device for steel pipe piles in water. Background Technology

[0002] In the construction of bridges in waterways, due to navigation requirements, temporary steel trestle bridges and underwater drilling platforms are typically erected to ensure the construction of the bridge's pile foundations and substructure. These steel trestle bridges and drilling platforms generally use steel pipe piles as their foundations. The overall structure is considered a high-risk, large-scale project; therefore, the installation accuracy of the steel pipe piles plays a crucial role in the stability of the entire steel trestle bridge and drilling platform. However, in actual implementation, due to various factors such as the bridge span, the size and number of steel pipe piles, and complex hydrological conditions, the positioning of the steel pipe piles is difficult, and the verticality of the piles is hard to control, making it difficult to guarantee the overall structural stability. Summary of the Invention

[0016] The present invention will now be described in detail with reference to the accompanying drawings: as shown in the drawings Figures 1 to 3 As shown, this utility model includes a support frame 1 with a square frame structure; the support frame 1 is divided into upper and lower frames 11, which are symmetrically distributed and connected and fixed at their rear ends by a connecting frame 12. The front ends of the two frames 11 are respectively provided with a horizontal adjustment component 2 and a vertical adjustment component 3, and the vertical positioning of the steel pipe pile 4 is achieved by adjusting the horizontal adjustment component 2 and the vertical adjustment component 3. A counterweight beam 5 is fixed at the rear end of the upper frame 11 of the support frame 1, and the support frame 1 is fixed to the bridge by the counterweight beam 5. The counterweight beam 5 is made of two large I-beams and is fixed on both sides of the rear end of the upper frame 11, which increases the load on the bridge, prevents the structure from overturning, and plays an overall anti-overturning role.

[0017] The frame 11 includes two longitudinal H-beams 11-1 and two transverse channel steels 11-2. The two transverse channel steels 11-2 are fixed between the two longitudinal H-beams 11-1 by welding and are located at the rear end of the frame 11.

[0018] The connecting frame 12 includes two vertical channel steels 12-1 and one diagonal channel steel 12-2. The two vertical channel steels 12-1 are fixed between the upper and lower frames 11 by welding, and the two vertical channel steels 12-1 are distributed one-to-one with the two horizontal channel steels 11-2 respectively. The diagonal channel steel 12-2 is fixed between the two vertical channel steels 12-1 by welding.

[0019] The lateral adjustment assembly 2 on each layer of frame 11 includes two lateral adjustment shafts 21 and several lateral slide rails 22. The two lateral adjustment shafts 21 are fixed at the front end between two longitudinal I-beams 11-1 and have insertion holes for inserting steel pipe piles 4. The several lateral slide rails 22 are movably connected between the two lateral adjustment shafts 21, and several adjusting nuts 6 are connected to the lateral adjustment shafts 21. Adjusting nuts 6 are also provided on both sides of each end of each lateral slide rail 22. The lateral slide rails 22 mainly serve as lateral limiters. The lateral slide rails 22 can slide left and right through the lateral adjustment shafts 21 to limit the lateral displacement of the steel pipe piles 4 and adjust the lateral spacing of the steel pipe piles.

[0020] On each layer of frame 11, the front ends of the two longitudinal I-beams 11-1 are fixed with mounting plates 13 for installing longitudinal adjustment components 3 by welding. There are four mounting plates 13. Two mounting plates 13 are installed along the length of each longitudinal I-beam 11-1. One mounting plate 13 is flush with one of the transverse channel steels 11-2, and the other mounting plate 13 is located at the end of the longitudinal I-beam 11-1.

[0021] The longitudinal adjustment assembly 3 on each layer of frame 11 includes four longitudinal adjustment shafts 31 and two longitudinal slide rails 32. Two longitudinal adjustment shafts 31 are installed on each of the two mounting plates 13 on each longitudinal I-beam 11-1. The two longitudinal slide rails 32 are movably connected between the four longitudinal adjustment shafts 31, and several adjusting nuts 6 are connected to the longitudinal adjustment shafts 31. Adjusting nuts 6 are also provided on both sides of each end of each longitudinal slide rail 32. The longitudinal slide rails 32 mainly serve a longitudinal limiting function. The longitudinal slide rails 32 can slide back and forth through the longitudinal adjustment shafts 31 to limit the longitudinal displacement of the steel pipe pile 4, and together with the transverse slide rails 22, they position the diameter of the steel pipe pile 4.

[0022] The longitudinal adjustment component 3 is located above the lateral adjustment component 2, and the longitudinal adjustment component 3 and the lateral adjustment component 2 are arranged in a cross-shaped staggered pattern.

[0023] The adjusting nut 6 is located on the horizontal adjusting shaft 21 and the vertical adjusting shaft 31, and serves to fix the horizontal slide rail 22 and the vertical slide rail 32.

[0024] The working principle of this utility model is as follows: First, the number of transverse slide rails 22 is determined according to the number of steel pipe piles 4. Generally, one steel pipe pile 4 is equipped with two transverse slide rails 22, but the steel pipe pile 4 located on the side of the support frame 1 can be equipped with one transverse slide rail 22, because one side can abut against the longitudinal I-beam 11-1. Then, the diameter of the steel pipe pile 4 is determined by the sliding of the transverse slide rails 22 and the longitudinal slide rails 32, and it is ensured that the transverse slide rails 22 and the longitudinal slide rails 32 on the upper and lower frames 11 are aligned in the vertical direction. Finally, the steel pipe pile 4 is vertically placed between the preset transverse slide rails 22 and the longitudinal slide rails 32 and submerged in water. At this time, the adjustment nuts 6 on both sides of the transverse slide rails 22 and the longitudinal slide rails 32 are used to limit the movement, that is, the transverse slide rails 22 and the longitudinal slide rails 32 abut against the circumferential wall of the steel pipe pile 4.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
