Description

Technical Field

[0001] This utility model relates to steel structure production equipment for buildings, specifically to a steel structure welding device for buildings. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to the uncertainty and flexibility of construction, steel structures vary in size and model. Because of their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion and generally require rust removal, galvanizing, or painting, as well as regular maintenance, which necessitates the use of welding equipment.

[0003] Meanwhile, welded joints in building steel structures often have complex shapes, including cross joints at different angles and positions. While automated welding technology is widely used in some industrial sectors, manual welding remains a more suitable option in the welding process of building steel structures due to the high requirements for welding quality, process flexibility, and adaptability, as well as the complexity of site conditions. Skilled welders can better ensure welding quality and structural safety.

[0004] CN221185211U discloses a steel structure welding tool. This device, through the arrangement of a support plate and a welding table, can better fix the steel structure, facilitating subsequent welding work; through the arrangement of heat dissipation components, it can dissipate heat from the welded steel structure, facilitating subsequent processing. However, this device has the following drawbacks: 1. The position of the heat dissipation component (heat dissipation device) is fixed. However, during welding work, the welding position needs to be constantly adjusted, and the heat dissipation component cannot be adjusted according to the adjustment of the welding position, affecting the heat dissipation effect. 2. The transmission rod is driven by a motor to rotate, and the transmission rod drives the spray head to swing. The spray head can only rotate, not rise or fall, and the spray head cannot be adjusted according to the height of the weld, which is a limitation. Utility Model Content

[0005] The purpose of this utility model is to address the technical problems existing in the prior art: to provide a steel structure welding device for construction in which the position of the atomizing nozzle and the spraying angle can be flexibly adjusted according to the welding position.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The welding table for supporting the steel structure is arranged in the middle of the workbench. The limiting mechanism for fixing the steel structure on the front and rear sides is arranged on the workbench. Two groups of cooling mechanisms are arranged on the left and right sides of the welding table. The cooling mechanism includes an atomizing nozzle, a mounting shell, a first mounting frame, a front and rear translation mechanism, and a rotating and lifting mechanism. The atomizing nozzle is relatively fixed to the mounting shell. The mounting shell is connected to the first mounting frame through the rotating and lifting mechanism, so that the mounting shell can lift relative to the first mounting frame and rotate around the rotation center extending in the front and rear directions. The first mounting frame is installed on the workbench through the front and rear translation mechanism, so that the first mounting frame can translate back and forth relative to the workbench.

[0016] Preferably, there are two sets of limiting mechanisms, located at the front and rear ends of the worktable; and two sets of cooling mechanisms, located at the left and right ends of the worktable.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to specific embodiments.

[0032] A steel structure welding device for construction includes a workbench, a limiting mechanism, a welding table, and a cooling mechanism. The welding table for supporting the steel structure is located in the middle of the workbench. The limiting mechanism for fixing the steel structure on the front and rear sides is located on the workbench. Two sets of cooling mechanisms are located on the left and right sides of the welding table. The cooling mechanism includes an atomizing nozzle, a mounting housing, a first mounting frame, a front-back translation mechanism, and a rotation lifting mechanism. The atomizing nozzle is fixed relative to the mounting housing. The mounting housing is connected to the first mounting frame through the rotation lifting mechanism, so that the mounting housing rises and falls relative to the first mounting frame and rotates along a rotation center extending in the front-back direction. The first mounting frame is mounted on the workbench through the front-back translation mechanism, so that the first mounting frame translates back and forth relative to the workbench.

[0033] The rotary lifting mechanism includes two first electric telescopic rods, two hinge blocks, two connecting blocks, and a slider. A groove is provided at the bottom of the mounting housing. The first mounting frame, first electric telescopic rod, hinge block, and connecting block are connected sequentially from bottom to top. In the left-right direction, the connecting block corresponding to the inner first electric telescopic rod is fixedly connected to the bottom of the mounting housing, and the connecting block corresponding to the outer first electric telescopic rod is connected to the slider, which slides along the groove. The two first electric telescopic rods of a rotary lifting mechanism are arranged in the left-right direction, jointly driving the lifting and rotation of the atomizing nozzle. When the two first electric telescopic rods lift synchronously, the atomizing nozzle lifts. When the two first electric telescopic rods have a height difference, the atomizing nozzle rotates around the inner hinge block, and the slider translates along the groove. Through the arrangement of the slider and groove, as well as the outer hinge block, the position of the outer first electric telescopic rod is adapted to the position of the mounting housing.

[0034] The first mounting bracket is U-shaped, which allows space in the middle for the atomizing nozzle to rise, fall, and rotate, forming a protective structure at the front and back. The first electric telescopic rod is located in the middle of the first mounting bracket.

[0035] The forward and backward translation mechanism is an electric slide rail, through which the first mounting bracket moves forward and backward relative to the worktable. The electric slide rail is waterproof.

[0036] The upper end of the welding table is provided with an arc-shaped groove penetrating in the front-back direction for placing and assisting in positioning the steel structure.

[0037] The limiting mechanism includes a second mounting frame, a second electric telescopic rod, and a limiting plate. The second mounting frame is fixed on the workbench. There is a space on the second mounting frame for the steel structure to pass through. The second electric telescopic rod is fixed on the second mounting frame and drives the limiting plate to move up and down, thereby loosening or pressing the steel structure. The limiting plate is arranged at the bottom of the second electric telescopic rod.

[0038] The second mounting frame is in a "hui" shape. The second electric telescopic rod passes through the upper section of the second mounting frame to press the steel structure against the lower section of the second mounting frame.

[0039] The installation shell is a cubic hollow structure; the cooling mechanism further includes a water outlet pipe and a water delivery hose; the water delivery hose passes through the outer wall of the installation shell, and the rigid water outlet pipe passes through the upper wall of the installation shell and is fixedly connected to the installation shell. The water delivery hose, the water outlet pipe, and the atomizing nozzle are connected in sequence.

[0040] A steel structure welding device for construction also includes a water supply system connected to the water delivery hose; each atomizing nozzle is connected to a water supply system, or two atomizing nozzles are connected in parallel to a water supply system. In this embodiment, two atomizing nozzles are connected in parallel to a water supply system, and the water supply system is provided with a water pump.

[0041] The number of the limiting mechanisms is two groups, which are arranged at the front end and the rear end of the workbench; the number of the cooling mechanisms is two groups, which are arranged at the left end and the right end of the workbench. With this structure, the overall shape is more concise.

[0042] By setting the cooling mechanism in the present utility model, connecting the water delivery hose to the water supply system, the welding position can be sprayed with water for cooling treatment through the atomizing nozzle. If the welding position point changes, the front-back position of the atomizing nozzle can be changed by controlling the electric slide rail; the height of the atomizing nozzle can be adjusted by controlling the telescopic length of the first electric telescopic rod. At the same time, by adjusting the length difference between the two first electric telescopic rods on one side, the spraying angle of the atomizing nozzle can be adjusted to spray upward or downward, and the spraying range of the atomizing nozzle becomes larger, the cooling mechanism is more flexible and convenient to use, and the cooling effect is good.

[0043] When the present utility model is implemented, it is operated according to the following steps:

[0044] 1) First, place the steel structure to be welded in the arc-shaped groove of the welding table 3, and control the second electric telescopic rod 202 to drive the limiting plate 203 to move downward to press and fix the steel structure.

[0045] 2) Then use the welding device to weld the steel structure, and connect the water delivery hose 410 to the external water supply system, and the welding place can be sprayed with water for cooling through the atomizing nozzle 409.

[0046] 3) Finally, the position of the atomizing nozzle 409 can be adjusted according to the change of the welding position. The position of the atomizing nozzle 409 can be moved by controlling the electric slide rail 411. The height of the atomizing nozzle 409 can be adjusted by controlling the synchronous extension and retraction of the two first electric telescopic rods 405 of a cooling mechanism. At the same time, the spraying angle of the atomizing nozzle 409 can be adjusted by adjusting the difference in the extension and retraction lengths of the two first electric telescopic rods 405, so that it sprays upward or downward.

[0047] After adopting the technical solution of this utility model, the front and rear position, high and low position, and spraying angle of the atomizing nozzle can be adjusted in real time according to the changes in the welding part, which has a better cooling effect, and the cooling range that can be covered by the two atomizing nozzles is larger.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
