Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding construction, in particular to a welding device suitable for high-altitude welding of special-shaped steel structures. Background Art

[0002] Steel structures are widely used in current construction, and welding is a common practice. Welding produces a large amount of high-temperature slag, which can easily cause fires and burns if not handled properly. Therefore, a fire hopper is often installed below the welding site to collect and dispose of the high-temperature slag, preventing accidents and damage caused by the slag splashing.

[0003] Conventional welding hoppers are primarily rectangular structures positioned directly below the welding position. While they can catch slag from square structures and small areas, they cannot cover beam-column junctions or irregularly shaped structures, making it difficult to effectively collect welding slag. Traditional high-altitude welding hoppers are primarily suspended structures, but lack a suspension point at the top for curtain wall keel welding, making them difficult to secure during the welding process. Furthermore, existing welding hoppers lack incomplete high-altitude welding facilities and an effective fixing structure, resulting in low slag collection efficiency.

[0004] Clearly, there's still room for improvement in the fire buckets used in steel structure welding. Adjustments and optimizations should be made to improve their ability to collect welding slag at irregular structural locations, such as beam-column junctions, and to improve the fixation of fire buckets when there's no upper hanging area. This will improve the effectiveness of curtain wall stud welding. Therefore, a more reasonable technical solution is needed to address the technical issues inherent in existing technologies.

[0005] Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the Invention

[0006] In order to overcome at least one of the defects mentioned above, the present invention proposes a welding device suitable for high-altitude welding of special-shaped steel structures, which aims to receive welding slag in special-shaped spaces through a flexibly adjustable adjustment rod structure, thereby avoiding the occurrence of welding slag splashing and improving the safety of welding.

[0007] In order to achieve the above-mentioned purpose, the fire connection device disclosed in the present invention can adopt the following technical solutions: A fire connection device suitable for high-altitude welding of special-shaped steel structures includes a fire connection tray body, which is provided with a plurality of adjustment rods that can be telescopically adjusted toward the front end, and adjacent adjustment rods are tightly fitted to form a receiving surface; the front ends of the adjustment rods are provided with a magnetic adsorption structure for matching the steel structure body.

[0008] The aforementioned welding device utilizes the welding tray as the primary slag receiving structure. Adjustable rods extend forward from the tray, forming a complete mating surface beneath the welding position on the steel structure to receive the solder left during the welding operation. Because the extension of each adjusting rod is independent of the others, when welding irregularly shaped structures such as corners, each adjusting rod can be extended forward until it rests against the steel structure, forming a corresponding receiving surface, making it convenient to use.

[0009] Furthermore, the front end of the adjustment rod and the steel structure are coupled via a magnetic attraction structure, leveraging the inherent ferromagnetic properties of the steel structure to achieve a tight fit between the adjustment rod and the steel structure. While this structure is not strictly limited, an optimization is presented herein, offering one feasible option: the magnetic attraction structure includes a magnet disposed at the front end of the adjustment rod. In this embodiment, the magnet can be a strong magnet and can be integrally molded with the adjustment rod, bonded, or formed into a caliper.

[0010] Furthermore, when specifically setting the magnet, considering that the magnetic attraction force affects the tightness of the fit, it is necessary to increase the adsorption area of ​​the magnet, thereby improving the adsorption force. The setting structure of the magnet is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the front end of the adjustment rod is formed with a longitudinal mating head, and the magnet is connected and fixed to the mating head. When the above solution is adopted, the mating head and the adjustment rod are integrally formed, or connected and formed by fasteners. The magnet fits the vertical surface of the mating head to form a larger adsorption surface, thereby improving the adsorption and fitting force.

[0011] Furthermore, the fire tray body and the adjustment rod slide together to achieve the telescopic movement of the adjustment rod. This can be achieved in a variety of ways, and the structure is not limited to a single one. Here, we optimize and propose one feasible option: the fire tray body is formed with an adjustment cavity, and the adjustment rod is slidably inserted into the adjustment cavity. When adopting this solution, the adjustment cavity can be a whole cavity structure or a plurality of separate cavity structures.

[0012] Furthermore, the structure within the adjustment cavity can be optimized to facilitate more stable guidance of the adjustment rod. Here, we propose a feasible optimization option: a plurality of chute grooves are formed within the adjustment cavity, and the adjustment rods mate with the chute grooves one by one. In this solution, the adjustment rod slides within the chute grooves, or the adjustment rod is provided with a corresponding protrusion that fits into and slides along the chute grooves. When the protrusion structure is formed on the adjustment rod, the chute grooves can mate with the upper surface, lower surface, or left and right surfaces of the adjustment rod.

[0013] Furthermore, the adjustment rod slides relative to the fire receiving tray body. To prevent the adjustment rod from falling off the fire receiving tray body, the matching structure between the fire receiving tray body and the adjustment rod can be improved. Here, an optimization is made and one of the feasible options is proposed: a limit structure is provided on the fire receiving tray body, the limit structure includes an adjustment bolt extending into the adjustment cavity, the front end of the adjustment bolt is connected to a limit plate, and the limit plate corresponds to the limit protrusion on the adjustment rod to prevent the adjustment rod from sliding out of the adjustment cavity. When adopting the above solution, the adjustment bolt is used to rotate and adjust the distance between the limit plate and the adjustment rod, so that the limit plate is kept within the appropriate limit distance; and the limit protrusion can be set at the tail of the adjustment rod or other corresponding position, and when the adjustment rod is extended outward to the maximum extent, it will conflict with the limit plate, thereby preventing the adjustment rod from falling off.

[0014] Furthermore, adjacent adjustment rods fit together to form a joint surface. The adjustment rods can be constructed in a variety of forms to maintain good integrity of the joint surface and avoid gaps that could cause welding slag leakage. This structure is not strictly limited. Here, we optimize and propose one feasible option: the adjustment rods are polygonal, with the left and right side surfaces of the adjustment rods serving as joint surfaces for mating with adjacent adjustment rods, and the joint surfaces of adjacent adjustment rods form a directional mating structure. When adopting this solution, the adjustment rods can be rectangular strips, with adjacent adjustment rods tightly fitting together to form a flat joint surface.

[0015] Furthermore, a directional mating structure further stabilizes the fit of adjacent adjustment rods, forming an integrated structure. This structure is not strictly limited, and optimization is provided herein, with one feasible option being proposed: the directional mating structure includes directional grooves and directional sliders correspondingly disposed on adjacent mating surfaces. When adopting this solution, the directional grooves can be configured as trapezoidal grooves, with the width of the groove opening being smaller than the width of the groove bottom. The directional sliders can be correspondingly trapezoidal bars, which, in conjunction with the reminder grooves, maintain a tight fit between adjacent adjustment rods in the lateral direction.

[0016] Furthermore, after the adjustment rod is retracted back into the fire tray body, it is necessary to maintain the stability of the adjustment rod in the retracted state to prevent it from automatically extending uncontrollably and causing damage. This can be achieved in a variety of ways, and an optimization is proposed herein, wherein one feasible option is: a detachable bottom plate is formed at the rear end of the fire tray body, and the bottom plate cooperates with the fire tray body to form a locking cavity. When the adjustment rod is retracted into the fire tray body, its rear end is located in the locking cavity and locked. When the rear end of the adjustment rod is unlocked, it extends toward the front end of the fire tray body. When the above solution is adopted, a concave cavity is formed on the fire tray body, and the bottom plate seals the concave cavity to form a locking cavity.

[0017] Furthermore, the locking scheme for the adjustment rod can adopt a variety of methods, and its structure is not limited to a single method. Here, we optimize and propose one feasible option: a locking member is provided in the fire receiving tray body, and a limit hole is correspondingly provided on the adjustment rod. When the rear end of the adjustment rod extends into the locking cavity, the locking member and the limit hole are locked together. When adopting this solution, the locking member can adopt an elastic structure, which can be disengaged under the action of tension after docking with the limit hole. This can achieve a certain degree of locking of the adjustment rod while ensuring the flexibility and convenience of the adjustment rod in use.

[0018] Furthermore, the specific locking member structure and its matching method can adopt multiple schemes, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: a locking hole is formed on the inner wall of the locking cavity, and the locking member includes an elastic locking tongue arranged in the locking hole. The rear end of the adjustment rod forms a guide surface, and the elastic locking tongue is retracted into the locking hole through the guide surface and the adjustment rod surface. When the limiting hole and the elastic locking tongue are aligned, the elastic locking tongue pops out and snaps into the limiting hole. When adopting the above scheme, the elastic locking tongue can adopt a long strip structure or a ball structure. The elastic locking tongue extends toward the adjustment rod through the locking hole and can return to the locking hole under the pressure of the elastic rod. However, when it is aligned with the limiting hole, it pops out from the locking hole and snaps into the limiting hole.

[0019] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in the present invention include: The present invention cooperates with the fire receiving tray body by arranging an adjusting rod, and adopts a structure in which multiple adjusting rods extend forward respectively, and are matched under the welding position of the steel structure to fit the special-shaped construction area to form a flat receiving surface structure, thereby avoiding the splashing of welding slag at the welding position, thereby ensuring the safety of the welding construction operation; the device has a simple and ingenious structure, is flexible and convenient to use, can be used in a variety of construction environments, and can improve the efficiency and safety and reliability of steel structure welding construction.

[0028] This embodiment will be further explained below with reference to the accompanying drawings and specific examples.

[0029] Aiming at the problems in the prior art of steel structure welding construction such as inconvenient setting of the fire tray and insufficient collection of welding slag, which lead to certain safety hazards in the steel structure welding construction, the following embodiments are optimized and overcome the defects in the prior art.

[0030] Example like Figures 1 to 6 As shown, this embodiment provides a fire connection device suitable for high-altitude welding of special-shaped steel structures, including a fire connection tray body 1, the fire connection tray body 1 is provided with a plurality of adjustment rods 2 that are telescopically adjusted toward the front end, and adjacent adjustment rods 2 are tightly fitted to form a receiving surface; the front end of the adjustment rod 2 is provided with a magnetic adsorption structure for matching the main body of the steel structure 9.

[0031] The welding device disclosed in this embodiment utilizes a welding tray body 1 as the primary slag receiving structure. Adjustable rods 2 extend forward from the tray, forming a complete mating surface below the welding position of the steel structure 9 to receive the solder dropped during the welding operation. Because the extension of each adjustable rod 2 is independent of the others, when welding irregularly shaped structures such as corners of the steel structure 9, each adjustable rod 2 can be extended forward until it abuts the steel structure 9, forming a corresponding receiving surface for the irregular structure, making it convenient to use.

[0032] The front end of the adjustment rod 2 and the steel structure 9 are matched through a magnetic adsorption structure. By utilizing the inherent ferromagnetic characteristics of the steel structure 9, the adjustment rod 2 and the steel structure 9 can be tightly fitted. The structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the magnetic adsorption structure includes a magnet 8 disposed at the front end of the adjustment rod 2. When adopting the above solution, the magnet 8 can be a strong magnet 8, which can be integrally formed with the adjustment rod 2, bonded, or caliper-molded.

[0033] When specifically setting the magnet 8, considering that the magnetic attraction strength affects the tightness of the fit, it is necessary to increase the adsorption area of ​​the magnet 8, thereby improving the adsorption force. The setting structure of the magnet 8 is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the front end of the adjustment rod 2 is formed with a longitudinal mating head 201, and the magnet 8 is connected and fixed to the mating head 201. When adopting the above solution, the mating head 201 is integrally formed with the adjustment rod 2, or is connected and formed by fasteners. The magnet 8 fits the vertical surface of the mating head 201 to form a larger adsorption surface, thereby improving the adsorption and fitting force.

[0034] The fire tray body 1 and the adjustment rod 2 are slidably engaged to achieve the telescopic movement of the adjustment rod 2. This can be achieved in a variety of ways, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the fire tray body 1 is formed with an adjustment cavity 101, and the adjustment rod 2 is slidably inserted in the adjustment cavity 101. When adopting the above solution, the adjustment cavity 101 can be a whole cavity structure or a plurality of separate cavity structures.

[0035] The structure within the adjustment cavity 101 can also be optimized to facilitate more stable guidance of the adjustment rod 2. This embodiment optimizes and adopts one feasible option: a plurality of chute grooves are formed within the adjustment cavity 101, and the adjustment rod 2 corresponds to each of the chute grooves. When adopting this solution, the adjustment rod 2 slides within the chute grooves, or the adjustment rod 2 is provided with a corresponding protrusion structure that fits into the chute groove and slides along the chute groove. When the protrusion structure is formed on the adjustment rod 2, the chute groove can correspond to the upper surface, lower surface, or left and right surfaces of the adjustment rod 2.

[0036] The adjusting rod 2 slides relative to the fire receiving tray body 1. To prevent the adjusting rod 2 from falling off the fire receiving tray body 1, the matching structure between the fire receiving tray body 1 and the adjusting rod 2 can be improved. This embodiment optimizes and adopts one of the feasible options: a limiting structure is provided on the fire receiving tray body 1, which includes an adjusting bolt 6 extending into the adjusting cavity 101. The front end of the adjusting bolt 6 is connected to a limiting plate 7. The limiting plate 7 corresponds to the limiting protrusion 5 on the adjusting rod 2 to prevent the adjusting rod 2 from sliding out of the adjusting cavity 101. When adopting the above solution, the adjusting bolt 6 is used to rotate and adjust the distance between the limiting plate 7 and the adjusting rod 2, so that the limiting plate 7 is maintained within the appropriate limiting distance; and the limiting protrusion 5 can be provided at the tail of the adjusting rod 2 or other corresponding position. When the adjusting rod 2 is extended outward to the maximum extent, it will interfere with the limiting plate 7, thereby preventing the adjusting rod 2 from falling off.

[0037] Adjacent adjustment rods 2 fit together to form a joint surface. The adjustment rods 2 can be constructed in a variety of forms to maintain good integrity of the joint surface and avoid gaps that could cause welding slag leakage. The structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the adjustment rod 2 is polygonal, with the left and right side surfaces of the adjustment rod 2 serving as joint surfaces for mating with adjacent adjustment rods 2, and a directional mating structure is formed on the joint surfaces of adjacent adjustment rods 2. When adopting the above solution, the adjustment rods 2 can be a rectangular strip structure, with adjacent adjustment rods 2 tightly fitting together to form a flat joint surface.

[0038] The directional mating structure stabilizes the fit of adjacent adjustment rods 2, forming an integrated structure. This structure is not strictly limited. This embodiment optimizes and employs one feasible option: the directional mating structure includes directional grooves and directional sliders correspondingly disposed on adjacent mating surfaces. When this solution is employed, the directional grooves can be trapezoidal, with the width of the groove opening being smaller than the width of the groove bottom. The directional sliders can be trapezoidal, and when combined with the reminder grooves, they maintain a tight fit between adjacent adjustment rods 2 in the lateral direction.

[0039] After the adjustment rod 2 is retracted back into the fire tray body 1, it is necessary to maintain the stability of the adjustment rod 2 in the retracted state to prevent it from automatically extending uncontrollably and causing damage. This can be achieved in a variety of ways. This embodiment is optimized and adopts one feasible option: a detachable bottom plate 4 is formed at the rear end of the fire tray body 1. The bottom plate 4 cooperates with the fire tray body 1 to form a locking cavity. When the adjustment rod 2 is retracted into the fire tray body 1, its rear end is located in the locking cavity and locked. When the rear end of the adjustment rod 2 is unlocked, it extends toward the front end of the fire tray body 1. When adopting the above solution, a concave cavity is formed on the fire tray body 1, and the bottom plate 4 seals the concave cavity to form a locking cavity.

[0040] The locking scheme for the adjustment rod 2 can be implemented in a variety of ways, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: a locking member 3 is provided in the fire receiving tray body 1, and a limiting hole 202 is correspondingly provided on the adjustment rod 2. When the rear end of the adjustment rod 2 extends into the locking cavity, the locking member 3 cooperates with the limiting hole 202 to lock. When adopting the above scheme, the locking member 3 can adopt an elastic structure, and after docking with the limiting hole 202, it can be disengaged under the action of tension, thereby achieving a certain degree of locking of the adjustment rod 2 while ensuring the flexibility and convenience of the adjustment rod 2 in use.

[0041] The specific structure of the locking member 3 and its matching method can adopt a variety of schemes, and its structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: a locking hole is formed on the inner wall of the locking cavity, and the locking member 3 includes an elastic locking tongue arranged in the locking hole. The rear end of the adjustment rod 2 forms a guide surface, and the elastic locking tongue is retracted into the locking hole through the guide surface and the surface of the adjustment rod 2. When the limiting hole 202 is aligned with the elastic locking tongue, the elastic locking tongue pops out and snaps into the limiting hole 202. When adopting the above scheme, the elastic locking tongue can adopt a long strip structure or a ball structure. The elastic locking tongue extends toward the adjustment rod 2 through the locking hole and can return to the locking hole under the pressure of the elastic rod. However, when it is aligned with the limiting hole 202, it pops out from the locking hole and snaps into the limiting hole 202.

[0042] The above are the implementation methods listed in this embodiment, but this embodiment is not limited to the above optional implementation methods. Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can derive other various implementation methods based on the inspiration of this embodiment. The above specific implementation methods should not be understood as limiting the scope of protection of this embodiment. The scope of protection of this embodiment should be based on the definition in the claims.
