Abstract

Technical Field
[0001] The utility model belongs to the technical field of bridge construction and relates to a welding auxiliary supporting device. Background Art
[0002] With the widespread use of steel bridges in transportation infrastructure construction, bridge structures are increasingly trending towards novel structures and aesthetically pleasing shapes. This structural diversity has led to a significant increase in situations where space is limited and welding positions are difficult to operate. This often results in limited welding space and difficulty welding full penetration welds on both sides. This problem can be solved by using a welding process that uses a ceramic backing with a single-sided welding and double-sided forming process. Using a ceramic backing not only improves weld quality but also increases efficiency, ensures good weld formation, reduces labor intensity, and minimizes occupational hazards.
[0003] However, when the ceramic liner cannot be installed in a confined space, the conventional practice in the past is to attach a steel liner. However, welding defects are often prone to occur at the root of the steel liner weld, and the weld quality is difficult to control. Summary of the Invention

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, 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 should fall within the scope of protection of the present invention.
[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate for the embodiments of the present invention described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed may also be "included" and "having"; for example, a process, method, system, product or device that may include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.
[0022] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text.
[0023] like Figure 1-Figure 2 As shown, the utility model is a welding auxiliary support device, comprising a base 1, a pad 6 fixed to the middle of the top surface of the base 1 by a double-sided adhesive film 2 and screws 3, and handles 4 are installed at both ends of the base 1.
[0024] A gasket groove is provided on the top of the base 1 for placing a gasket 6. Symmetrical support columns are provided at the bottom of the base 1 to resist vertical bending of the base 1.
[0025] The base 1 is made of a rigid metal material. The base 1 has a height of 25 mm, a width of 36 mm, and a pad groove depth of 7 mm.
[0026] Double-sided adhesive film 2, using aluminum foil material with double-sided adhesiveness, the metal has better heat resistance.
[0027] To further illustrate, the double-sided adhesive film 2 is bonded to the middle of the bottom surface of the gasket groove, and the length of the double-sided adhesive film 2 is adapted to the gasket 6 .
[0028] Screws 3 are threadedly installed on both sides of the gasket groove, pressing against the sides of gasket 6, thereby improving the connection strength between base 1 and gasket 6. The number of screws 3 determines the connection strength. In this embodiment, the screws 3 are evenly distributed along the longitudinal direction of base 1 by 30 mm.
[0029] The bottom of the pad 6 is bonded to the double-sided adhesive film 2. The top center of the pad 6 is a welding material volume groove for collecting melted welding materials. The two sides of the welding material volume groove are support planes for supporting the steel plate. The pad 6 is made of ceramic material and has low affinity with the welding material.
[0030] The lifting handle 4 consists of a steel wire rope, with its ends connected to a lifting eye and a handle fixing block, respectively. The lifting eye is fixed to the base 1, and the lifting eye is located above the base 1. The wire rope is made of φ3mm steel. The lifting handle 4 is used to lift the base 1 and the liner 6 together and pass under the weld seam. The lifting surfaces on both sides of the top of the liner 6 support the steel plates to be welded. The weld seam is located above the welding consumable volume groove. The lifting eye is secured by a fixing mechanism, such as a fixed shaft.
[0031] Since the base 1 and the gasket 6 are rectangular, there will be sagging in the middle. In order to eliminate the gap between the gasket 6 and the steel plate to be welded due to the sagging, hanging blocks 5 are installed at both ends of the base 1.
[0032] The pendant 5 includes a hanging rope, two ends of which are respectively connected to the handle and the pendant fixing member, and the pendant fixing member is located in the base 1.
[0033] In order to increase the torque, the drop block fixing piece is located outside the handle fixing block.
[0034] Base 1 must be made of a sufficiently rigid material to prevent deflection during installation, which could affect weld quality. Base 1 should have a certain degree of upward curvature, designed to follow a quadratic parabola. This ensures a closer fit between pad 6 and the welded component after handle 4 is pulled upward and secured. Base 1 should be short and should be tailored to the material's rigidity to prevent deflection during installation.
[0035] The bottom surface of the base 1 and the double-sided adhesive film 2 should be provided with ventilation holes to ensure good ventilation during the welding process.
[0036] The specific position of the handle 4 can be adjusted according to the length of the weld.
[0037] When the length of the base 1 is smaller than the length of the weld, the weld can be welded in sections according to the length of the base 1.
[0038] The shape of the base 1 can be appropriately adjusted according to the form of the weld joint to meet the needs of different types of joint welds.
[0039] The working process of this utility model is as follows:
[0040] Double-sided adhesive tape 2 is first bonded to base 1. The length of double-sided adhesive tape 2 is adjusted according to the length of the weld. The liner 6 is bonded and fixed to base 1 using double-sided adhesive tape 2. After the weld is completed, the double-sided adhesive tape 2 and liner 6 are removed together. After the liner 6 is bonded, it is tightened and fixed using screws 3 on both sides.
[0041] Move the device horizontally to the bottom of the steel plate to be welded, lift the lifting ring to raise the entire device until the lifting plane touches the bottom of the steel plate to be welded. After it is close, keep the pull ring fixed; then pull down the handle to increase the fit between the gasket 6 and the steel plate before welding.
[0042] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
