Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a welding device for building steel structure construction. Background Art

[0002] Steel structures are mainly composed of steel materials and are one of the main building structure types. Steel structures are mainly composed of components such as steel beams, steel columns, and steel trusses made of sections and steel plates. Welds, bolts, or rivets are usually used to connect each component or part. For steel structure welding in bridge construction, to ensure welding quality, in the manufacture of steel beams, welders, welding materials, welding methods, weld forms, welding equipment and tools, welding process parameters, welding process requirements, weld repair, welding inspection, etc. should be operated in accordance with relevant regulations.

[0003] When the existing devices perform welding work on steel structures, they mostly fix the steel structures by hand for convenience to carry out welding work, which is not convenient for the flexibility of the device. Moreover, when welding steel structures, the welding devices are mostly simple and cannot protect the welding workers during welding operations. During welding work, the sparks generated by welding will splash onto the operator, which is not convenient for the safety of the device. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A welding device for building steel structure construction according to the present invention includes a main body housing. One end of the inner cavity of the main body housing is threadedly connected with a threaded rod. A protection component is fixedly connected to the top of the outer surface of the main body housing. A clamping component is sleeved on the outer surface of the threaded rod. A dust collection component is fixedly connected to the middle of the inner cavity of the main body housing. A welding head is fixedly connected to the top of the outer surface of the dust collection component. After clamping and fixing the workpiece to be welded, by rotating the threaded rod, the threaded rod rotates in the inner cavity of the main body housing, so that the moving block moves on the threaded rod, thereby driving the clamping component to move, facilitating welding work for workpieces of different lengths. While rotating the threaded rod to drive the clamping housing to move, it drives the fixed rod to move in the inner cavity of the protection housing, so that when adjusting the movement of the clamping component, at the same time, the lifting plate moves in the inner cavity of the protection housing, which can protect the operator during welding work and prevent the sparks generated by welding from causing harm to the operator during welding work. While the clamping component moves, through the push of the telescopic rod, the cleaning plate moves in the inner cavity of the dust collection housing, preventing excessive waste chips from accumulating in the inner cavity of the dust collection housing and interfering with the normal operation of the dust collection component.

[0005] Preferably, the clamping component includes a clamping housing. A clamping ring is fixedly connected to the middle of the inner cavity of the clamping housing. A first connecting shaft is inserted into the middle of the inner wall of the clamping housing. The first connecting shaft penetrates through the inner wall of the clamping ring, and the outer surface of the first connecting shaft is slidably connected to the inner cavity of the clamping ring. A small connecting rod is rotatably connected to one end of the first connecting shaft close to the clamping housing. A second connecting shaft is rotatably connected to the end of the small connecting rod away from the first connecting shaft. A clamping block is fixedly connected to the end of the second connecting shaft away from the small connecting rod. A spring is sleeved on the outer surface of the second connecting shaft. One end of the spring close to the clamping housing is fixedly connected to the bottom of the inner cavity of the clamping housing, and the end of the spring away from the clamping housing is fixedly connected to the outer surface of the clamping ring. During operation, the steel bar to be welded is placed on the clamping component. Due to the weight of the steel bar itself, the clamping block moves downward. While the clamping block moves downward, it drives the second connecting shaft to move in the inner cavity of the clamping ring. While the second connecting shaft moves downward, it drives the small connecting rod to move, and at the same time, through the pulling of the small connecting rod, it drives the first connecting shaft to slide in the inner wall of the clamping ring, so that the clamping block on the inner wall of the clamping ring clamps and fixes the steel bar to be welded. In the present invention, by setting the clamping component, by increasing the clamping component, by the weight of the workpiece to be processed, and by the movement of the second connecting shaft in the inner cavity of the clamping ring, the small connecting rod pulls the first connecting shaft, so that the first connecting shaft drives the clamping block to move in the inner cavity of the clamping ring, thereby clamping and fixing the workpiece on the middle of the clamping ring, enabling the device to quickly fix the workpiece to be processed, facilitating the subsequent welding work, and improving the working efficiency of the device.

[0006] Preferably, the protection component includes a protection housing. On both sides of the inner cavity of the protection housing, there are sliding rods rotatably connected. A slider is sleeved on the outer surface of the sliding rod, and the outer surface of the sliding rod is slidably connected to the inner cavity of the slider. A fixed rod is fixedly connected to the outer surface of the clamping housing. One end of the fixed rod away from the clamping housing is fixedly connected to the outer surface of the slider. A lower fixed seat is fixedly connected to the top of the outer surface of the slider. A large connecting rod is rotatably connected to the inner wall of the lower fixed seat. One end of the large connecting rod away from the lower fixed seat is rotatably connected to an upper fixed seat. One end of the upper fixed seat away from the large connecting rod is fixedly connected to a lifting plate, and the outer surface of the lifting plate is slidably connected to the inner wall of the protection housing; after rotating the threaded rod to adjust the position of the clamping component, when the clamping housing moves, it drives the slider to slide on the sliding rod. At the same time, when the two sliders move relative to each other on the sliding rod, it drives the large connecting rod to move upward. Through the extrusion of the large connecting rod, the lifting plate moves upward in the inner cavity of the protection housing, so that when welding work is carried out, the lifting plate protects the operator and prevents the sparks generated during welding from splashing and injuring the staff. By setting the protection component in the present invention, when the workpiece is welded, it is necessary for the staff to observe beside. The sparks generated during welding of the workpiece may splash onto the staff. By adding the protection component, when the workpiece is welded, the lifting plate plays a role in protection. At the same time, after the welding work is completed, the protection component can be stored and will not affect the previous preparation work.

[0007] Preferably, the dust collection component includes a dust collection housing, on the outer surface of which a motor is fixedly connected. A fan blade is fixedly connected to the outer surface of the output end of the motor. A filter screen plate is fixedly connected to the inner cavity of the dust collection housing. In the middle of one end of the outer surface of the clamping housing close to the dust collection housing, a telescopic rod is fixedly connected. The end of the telescopic rod away from the clamping housing is fixedly connected to a cleaning plate. The telescopic rod penetrates the inner wall of the dust collection housing, and the outer surface of the telescopic rod is slidably connected to the inner wall of the dust collection housing. The outer surface of the cleaning plate is slidably connected to the inner wall of the dust collection housing. When the motor is turned on, the fan blade is driven by the output end of the motor to rotate in the inner cavity of the dust collection groove, so as to collect the waste chips generated during the welding work. The waste chips generated during the welding work are adsorbed in the inner cavity of the dust collection housing. When the threaded rod is rotated to adjust the clamping component, the clamping housing drives the telescopic rod to move while moving, so that the telescopic rod drives the cleaning plate to move in the inner cavity of the dust collection housing, thereby pushing the waste chips adsorbed in the inner cavity of the dust collection housing, so that the waste chips enter the bottom of the dust collection housing to prevent too much waste chips from accumulating in the inner cavity of the dust collection housing and interfering with the dust collection work. By setting the dust collection component in the present invention, a large amount of welding waste chips will be generated during the welding work. The waste chips will not only accumulate on the device, but also splash when the waste chips are generated, which may cause burns to the staff. By adding the dust collection component, the waste chips generated during the welding work can be collected, and the waste chips in the inner cavity of the dust collection housing can be pushed and collected by the cleaning plate, preventing too much waste chips from accumulating in the inner cavity of the cleaning housing and reducing the effect of the dust collection component.

[0008] Preferably, a moving block is fixedly connected to the top of the clamping housing, and the inner cavity of the moving block is threadedly connected to the outer surface of the threaded rod. In the present invention, the clamping component is moved by adjusting the threaded rod, and it can be adjusted according to workpieces of different lengths. At the same time when the clamping component moves, the protection component can perform a protection work to prevent the sparks generated by welding from splashing onto the operator. While the threaded rod drives the clamping component to move, the cleaning plate is driven by the telescopic rod to clean the inner cavity of the cleaning housing, preventing a large amount of waste chips from accumulating in the inner cavity of the cleaning housing, thereby improving the linkage of the device.

[0009] The beneficial effects of the present invention are as follows: (1) By setting the clamping component in the present invention, by increasing the clamping component, through the self-weight of the workpiece to be processed, the connecting shaft two moves in the inner cavity of the snap ring, so that the small connecting rod pulls the connecting shaft one, and the connecting shaft one drives the clamping block to move in the inner cavity of the snap ring, thereby clamping and fixing the workpiece on the middle part of the snap ring, enabling the device to quickly fix the workpiece to be processed, facilitating the subsequent welding work, and improving the working efficiency of the device at the same time.

[0010] (2) By providing a protection component in the present invention, when the workpiece is being welded, it is necessary for the staff to observe nearby. The sparks generated during the welding of the workpiece may splash onto the staff. By adding a protection component, when the workpiece is being welded, the lifting plate serves a protective function. At the same time, after the welding work is completed, the protection component can be stored without affecting the preparatory work in the early stage.

[0011] (3) By providing a dust collection component in the present invention, when the device is performing welding work, a large amount of welding waste chips will be generated. The waste chips will not only accumulate on the device, but also splash when generated, which may cause burns to the staff. By adding a dust collection component, the waste chips generated during the welding work can be collected, and the waste chips in the inner cavity of the dust collection housing can be pushed and collected by the cleaning plate to prevent excessive waste chips from accumulating in the inner cavity of the cleaning housing, reducing the effect of the dust collection component.

[0012] (4) By adjusting the threaded rod to move the clamping component in the present invention, it can be adjusted according to workpieces of different lengths. At the same time, when the clamping component moves, the protection component can perform a blocking and protecting function to prevent the sparks generated by welding from splashing onto the operator. When the threaded rod drives the clamping component to move, the cleaning plate is driven by the telescopic rod to clean the inner cavity of the cleaning housing, preventing a large amount of waste chips from accumulating in the inner cavity of the cleaning housing, thereby improving the linkage of the device.

[0016] Embodiment, use Figures 1-8 A welding device for construction steel structure construction according to an embodiment of the present invention will be described as follows.

[0017] As Figures 1-8As shown, a welding device for construction steel structures according to the present invention includes a main body housing 1. One end of the inner cavity of the main body housing 1 is threadedly connected to a threaded rod 2. A protection component 3 is fixedly connected to the top of the outer surface of the main body housing 1. A clamping component 4 is sleeved on the outer surface of the threaded rod 2.

A dust collection component 5 is fixedly connected to the middle of the inner cavity of the main body housing 1. A welding head 6 is fixedly connected to the top of the outer surface of the dust collection component 5. After clamping and fixing the workpiece to be welded, by rotating the threaded rod 2, the threaded rod 2 rotates in the inner cavity of the main body housing 1, causing the moving block 42 to move on the threaded rod 2, thereby driving the clamping component 4 to move, facilitating welding work for workpieces of different lengths. While rotating the threaded rod 2 to drive the clamping housing 41 to move, it drives the fixed rod 43 to move in the inner cavity of the protection housing 31, so that when adjusting the clamping component 4, the lifting plate 37 also moves in the inner cavity of the protection housing 31, protecting the operator during welding work and preventing the sparks generated during welding from harming the operator. While the clamping component 4 moves, the cleaning plate 56 is pushed by the telescopic rod 55 to move in the inner cavity of the dust collection housing 51, preventing excessive waste chips from accumulating in the inner cavity of the dust collection housing 51 and interfering with the normal operation of the dust collection component 5.

[0018] The clamping component 4 includes a clamping housing 41. A clamping ring 44 is fixedly connected to the middle of the inner cavity of the clamping housing 41.

One end of the spring 48 far from the clamping housing 41 is fixedly connected to the outer surface of the clamping ring 44. During operation, the workpiece to be welded is placed on the clamping component 4. Due to the weight of the steel bar itself, the clamping block 49 moves downward. While the clamping block 49 moves downward, it drives the second connecting shaft 47 to move in the inner cavity of the clamping ring 44. While the second connecting shaft 47 moves downward, it drives the small connecting rod 46 to move. At the same time, through the pulling of the small connecting rod 46, it drives the first connecting shaft 45 to slide in the inner wall of the clamping ring 44, so that the clamping block 49 on the inner wall of the clamping ring 44 clamps and fixes the steel bar to be welded.

At the same time, when the two sliders 33 move relatively on the sliding rod 32, it drives the large connecting rod 35 to move upward. Through the extrusion of the large connecting rod 35, the lifting plate 37 moves upward in the inner cavity of the protection housing 31. Thus, during the welding operation, the lifting plate 37 protects the operator and prevents the sparks generated during welding from splashing and injuring the staff.

When the threaded rod 2 adjusts the clamping component 4, when the clamping housing 41 moves, it drives the telescopic rod 55 to move, so that the telescopic rod 55 drives the cleaning plate 56 to move in the inner cavity of the dust collection housing 51, thereby pushing the waste chips adsorbed in the inner cavity of the dust collection housing 51, causing the waste chips to enter the bottom of the dust collection housing 51 to prevent too much waste chips from accumulating in the inner cavity of the dust collection housing 51 and interfering with the dust collection work.
