Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a pipe alignment tool. Background Technology
[0002] Currently, welding fixing pins are commonly used in pipe joint construction. By hammering the pins, pipes with large misalignments can be corrected to the same pipe center. This method requires welding fixing parts to the pipes in advance, and the fixing parts need to be cut after the pipe joint welding is completed, which affects the pipe performance and appearance to some extent. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a pipe alignment tool that is reusable, easy to carry, quick to assemble and disassemble, improves pipe alignment efficiency, and improves welding quality.
[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: a pipe fitting device is provided, including a fixed rod, an adjusting rod, a lower bracket and an upper bracket. The upper and lower ends of the fixed rod are bent horizontally to one side, so that an opening is provided on one side of the fixed rod. An adjusting rod is vertically installed on the upper bent part of the fixed rod, passing through the bent end. An upper bracket is rotatably installed on the lower end of the adjusting rod. A lower bracket corresponding to the upper bracket is provided at the lower part of the opening of the fixed rod.
[0005] In this technical solution, a fixing rod is installed as a docking base that can be disassembled and facilitates the connection of two pipes. The lower bracket and upper bracket are installed to align the pipe joints, facilitating quick welding and fixing. An adjusting rod is set to move the upper bracket up and down, simplifying the operation.
[0006] As a supplement to this technical solution, the fixed rod and the adjusting rod are connected by threads. This threaded connection allows the adjusting rod to always move in the vertical direction, and the movement of the adjusting rod is highly stable.
[0007] As a supplement to this technical solution, an adjustment handwheel is installed at the upper end of the adjustment rod.
[0008] As a supplement to this technical solution, the upper part of the upper bracket is provided with a ring-shaped docking sleeve, which is sleeved on the lower end of the adjusting rod.
[0009] Beneficial effects: This invention relates to a pipe alignment tool, which uses a fixed rod as a detachable and convenient docking base for connecting two pipes. The lower and upper brackets are used to align the pipe joints, facilitating quick welding and fixing. An adjusting rod is used to move the upper bracket up and down, simplifying operation. It features reusability, portability, quick assembly and disassembly, improved pipe alignment efficiency, and improved welding quality. Attached Figure Description

[0012] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0013] Embodiments of the present invention relate to a pipe alignment device, such as... Figure 1 — Figure 3 As shown, it includes a fixed rod 1, an adjusting rod 4, a lower bracket 2, and an upper bracket 3. The upper and lower ends of the fixed rod 1 are bent horizontally to one side, so that an opening is provided on one side of the fixed rod 1. An adjusting rod 4 is vertically installed on the upper bent part of the fixed rod 1, passing through the bent end. The lower end of the adjusting rod 4 is rotatably installed with the upper bracket 3. A lower bracket 2 corresponding to the upper bracket 3 is provided at the lower part of the opening of the fixed rod 1.
[0014] In this technical solution, a fixing rod 1 is installed as a docking base that can be disassembled and facilitates the connection of two pipes. The lower bracket 2 and the upper bracket 3 are installed to align the pipe joints, facilitating quick welding and fixing. An adjusting rod 4 is set to move the upper bracket 3 up and down, simplifying the operation.
[0015] As a supplement to this technical solution, the fixed rod 1 and the adjusting rod 4 are connected by threads. The threaded connection enables the adjusting rod 4 to move vertically at all times, and the movement stability of the adjusting rod 4 is high.
[0016] As a supplement to this technical solution, an adjusting handwheel 5 is installed on the upper end of the adjusting rod 4.
[0017] As a supplement to this technical solution, the upper bracket 3 is provided with a ring-shaped docking sleeve 6, which is sleeved on the lower end of the adjusting rod 4.
[0018] Example During operation, first place the fixing rod 1 at the joint of the two pipe openings, and place the ends of the two pipe openings on the lower bracket 2. At this time, due to the weight of the pipe body itself, the joint gap between the two pipe openings is offset to the upper part being larger than the lower part. Then, rotate the adjusting rod 4 by adjusting the handwheel 5. The adjusting rod 4 moves the upper bracket 3 downward, and the upper bracket 3 can press against the upper side of the two pipe openings. By pressing the two pipe openings with the upper bracket 3, the joint gap between the two pipe openings can be made equal. Then, weld on the exposed gap. After completion, remove the device and then fully weld the gap.
