Description

Technical Field

[0001] This application relates to the field of pile foundation construction technology in civil engineering, and in particular to a welding tool for splicing prestressed concrete square piles for riverbank protection. Background Technology

[0002] In the field of civil engineering, prestressed concrete square piles are widely used due to their high strength and durability. However, in the process of splicing piles, traditional splicing methods often rely on manual or mechanical assistance, resulting in many problems such as low splicing accuracy, low construction efficiency, and poor safety. Manual splicing depends entirely on the experience and skills of construction workers, making it difficult to guarantee splicing accuracy and posing certain safety hazards. While mechanically assisted splicing can improve efficiency, it usually requires equipment such as cranes, still necessitating manual intervention and limiting accuracy. Furthermore, although specialized splicing equipment can achieve high splicing accuracy, such equipment is typically bulky, expensive, and complex to operate, making it difficult to widely apply in small and medium-sized projects or temporary works.

[0003] Currently, the main drawbacks of existing pile splicing technology are low splicing accuracy, low construction efficiency, and poor safety. These shortcomings not only affect project quality but also increase construction costs and risks. The subjectivity and uncertainty of manual splicing make it difficult to guarantee splicing accuracy, while mechanically assisted splicing still requires manual intervention and cannot completely solve the accuracy problem. Although specialized pile splicing equipment can provide high-precision splicing, its high cost and complex operation make it unsuitable for small and medium-sized or temporary projects, hindering its widespread adoption.

Therefore, this application provides a welding tool for splicing prestressed concrete square piles for riverbank protection.

[0005] The present application provides a welding tool for splicing prestressed concrete square piles for riverbank protection, which adopts the following technical solution: a support frame with a "U" shape, a through hole located at the middle of the lower end face of the support frame, a first fixing clamp located at one end of the long end face of the through hole, a second fixing clamp located at the other end of the upper end face of the through hole, a connecting component located at the connection between the first and second fixing clamps and the support frame, a first adjusting seat located on one side of the first fixing clamp, a second adjusting seat located on one side of the second fixing clamp and relative to the first adjusting seat, an adjusting member located between the first adjusting seat and the second adjusting seat, a first connecting seat located at the other end of the first fixing clamp, a second connecting seat located at the other end of the second fixing clamp and relative to the first connecting seat, and a guide component located between the first connecting seat and the second connecting seat.

[0006] By adopting the above technical solution, the support frame adjusts the distance between the first and second fixed clamps by flexibly adjusting the distance between the first and second adjusting seats, thereby adapting to square tubes with different outer diameters. At the same time, the guide component ensures stability and accuracy during the clamping process.

[0007] As a preferred embodiment, the connecting assembly includes fixing pins respectively disposed at the connection points of the first adjusting seat, the second adjusting seat, the first connecting seat, and the second connecting seat with the support frame, and sliding holes disposed on the support frame that are adapted to the fixing pins, wherein the fixing pins pass through the sliding holes and are connected to the fixing nut.

[0027] The implementation principle of the welding tool for splicing prestressed concrete square piles for riverbank protection in this application embodiment is as follows: In use, the end of the square pile to be spliced ​​is inserted through the through hole 11 and placed between the first fixing clamp 21 and the second fixing clamp 22. The bidirectional screw 5 can rotate in both directions. Through the cooperation of the thread and the screw sleeve, the first adjusting seat 411 and the second adjusting seat 412 move relative to each other along the axial direction of the screw. The distance between the first fixing clamp 21 and the second fixing clamp 22 is adjusted by flexibly adjusting the distance between the first adjusting seat 411 and the second adjusting seat 412. During this process, when the second connecting seat 422 moves relative to the first connecting seat 421, the sliding rod 62 slides in the sliding sleeve 61 and applies tension through the tension spring 621, thereby adapting to square tubes with different outer diameters and sequentially clamping and fixing the square piles to be spliced.
