[0023] The embodiments of the present invention are described below.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, in the following description, descriptions of well-known structures are omitted to avoid unnecessarily obscuring the concept of the invention.

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figure 1 As shown, an auxiliary device and method for welding the main reinforcement bars of a steel cage include a gripping rod 1, a support rod 2, a fixing device 3, an adjusting device 4, a pressure plate 5, an adjusting handle 6, a rotating shaft 7, a fixing groove 8, a shim 9, and a telescopic rod 10. The support rod 2 is symmetrically arranged at both ends of the gripping rod 1 and is perpendicular to the gripping rod 1, forming a concave shape between the gripping rod 1 and the support rod 2. A fixing device 3 is provided at the opposite end of the end where the support rod 2 connects to the gripping rod 1, and an adjusting device is provided on the fixing device 3. The gripping rod 1 and the support rod 2 work together to maintain a distance between the fixing devices 3, facilitating the installation of the main reinforcement bars of the steel cage. The main reinforcement bars can be installed and fixed in sections within the fixing devices 3. The adjusting device 4 can be used to adjust the fixing devices 3, allowing for tightening and loosening. The adjusting device 4, in conjunction with the fixing devices 3, can tighten and adjust the connection of the main reinforcement bars of the steel cage, ensuring that two sections of the main reinforcement bars are tightly aligned, facilitating the welding work of the main reinforcement bars.

[0027] Preferably, such as Figure 2 As shown, the fixing device 3 is equipped with a pressure plate 5, which is located inside the fixing device 3. The main reinforcement bars of the steel cage can be fixed by moving the pressure plate 5. At the same time, the movement of the pressure plate 5 can move and adjust the main reinforcement bars of the steel cage within the fixing device 3. A shim 9 is also provided at the bottom of the pressure plate 5. The use of the shim 9 can improve the friction and improve the fixing stability. The pressure plate 5 is connected to the adjusting device 4, and the movement of the pressure plate 5 can be controlled by the adjusting device 4.

[0028] Preferably, the fixing device 3 is provided with a fixing groove 8, wherein the fixing groove 8 is disposed opposite to the pressure plate 5 in the fixing device 3. In this embodiment, the fixing groove 8 is set as a V-shaped fixing groove bottom plate, which is disposed on the opposite side of the pressure plate 5. After the main reinforcement of the steel cage is placed on the V-shaped fixing groove bottom plate, the main reinforcement of the steel cage can always be located in the middle gap of the V-shape, so that the main reinforcement of the steel cage maintains its position, which facilitates the docking and welding of the main reinforcement of the steel cage at both ends. After adjusting the position of the fixing groove 8 and the position of the main reinforcement of the steel cage, the main reinforcement of the steel cage can be kept in a concentric position, thereby improving the welding quality.

[0029] Preferably, an angle measuring instrument is installed on one side of the fixing device 3. After the main reinforcement bars of the steel cage are fixed in the fixing device 3, the angle measuring instrument can be used to determine the butt joint angle of the main reinforcement bars of the steel cage installed on the fixing device 3 at both ends, so that the main reinforcement bars of the steel cage can be smoothly butt jointed, and the concentric circles are in the same position, which facilitates the welding work of the user and improves the welding quality.

[0030] Preferably, the adjusting device 4 includes an adjusting handle 6, a rotating shaft 7, and a telescopic rod 10. The adjusting handle 6 is located at one end of the rotating shaft 7, which is mounted on the fixing device 3. Rotating the adjusting handle 6 causes the rotating shaft 7 to rotate, which in turn causes the telescopic rod 10 to extend or retract. The telescopic rod 10 is connected to the pressure plate 5, and the extension or retraction of the telescopic rod 10 allows the pressure plate 5 to move and be fixed within the fixing device 3. The use of the adjusting device 4 facilitates the fixing of the main reinforcement bars of the steel cage by the fixing device 3, improves efficiency, and enhances user-friendliness.

[0031] Preferably, such as Figure 4 As shown, the gripping rod 1 includes a first connecting tube and a second connecting tube, wherein the second connecting tube is embedded inside the first connecting tube. The second connecting tube can move, stretch, and contract within the first connecting tube. By moving the first connecting tube, the length of the gripping rod 1 can be adjusted, thereby adjusting the relative position of the fixing device 3. This facilitates the installation and welding of the main reinforcement bars of the steel cage. After the gripping rod 1 is adjusted in length, the second connecting tube can be fixed within the first connecting tube, improving the practicality of this embodiment.

[0032] Preferably, a rotating disk is provided at the connection between the support rod 2 and the fixing device 3, and the fixing device 3 can be rotated by the rotating disk to adjust the direction of use.

[0033] By utilizing the principle of parallel fixing with standardized tools and employing a combination of devices for processing, the manual labor rate is reduced, ensuring the health and safety of personnel. It effectively prevents quality defects caused by misaligned connections of reinforcing bars, and is easy to carry, simple to operate, highly stable, and can be used by pets, achieving cost reduction, efficiency improvement, and quick and convenient results.

[0034] By using the device of this invention, operation is simple and time-saving, enabling the installation of reinforcing bars to be completed faster with less manpower and less time. At the same time, it ensures that the upper and lower reinforcing bars are aligned and concentric. The device is easy to install and can be quickly fixed and dismantled, greatly reducing the use of manpower while ensuring personnel safety. It effectively improves construction efficiency, promotes the coordinated and rapid development of pile foundation projects, and optimizes costs, thus having high economic and social value.
