The feeding component 300 can simultaneously assemble two steel wing plates 103 vertically on both sides of the steel web 102.

The traveling welding component 201 includes a lateral rail 2011 installed on the side of the support plate 203. The cross section of the lateral rail 2011 is T-shaped. A sliding seat 2012 is slidably sleeved on the lateral rail 2011. The two slide together without deflection. A welding arm 2013 is arranged on the outer side of the sliding seat 2012. The outer end of the welding arm 2013 extends to the joint of the steel wing plate 103 and the steel web 102, which is convenient for welding the joint. A fixed rack 2015 is arranged on the outer side of the lateral rail 2011. The length of the fixed rack 2015 is consistent with the length of the lateral rail 2011. A traveling gear 216 for driving the sliding seat 2012 to move is meshed on the fixed rack 2015.

In this embodiment, preferably, multiple inner cross beams 104 are provided inside the lower cross frame 100 and the upper cross frame 101, and a cross plate is provided on the upper surface of the inner cross beam 104. The lifting cylinder 208 is embedded in the cross plate. The lifting cylinder 208 is vertically embedded inside the upper inner cross beam 104, and a limit plate 207 located at the end of the steel wing plate 103 is provided at the lower end of the lifting cylinder 208. The limit plate 207 is L-shaped, and the inner surface of the limit plate 207 is in contact with the end of the steel wing plate 103, so as to limit the front and rear directions of the steel wing plate 103.

Example 2

6 to 8 , a second embodiment of the present invention is shown, which is different from the previous embodiment.

In this embodiment, preferably, an adjusting member 204 is provided between the two lateral rails 2011. The adjusting member 204 can be used to drive and adjust the distance between the two lateral rails 2011, thereby changing the distance between the two welding arms 2013, which is convenient for adapting the length of the steel web 102 and welding the joint of the steel web 102 and the steel wing plate 103. A mounting plate 2043 is provided on the inner side surface of one of the lateral rails 2011 to facilitate the fixation of one of the adjustment racks 2042. Adjustment racks 2042 are provided on the inner side surfaces of the other lateral rail 2011 and the mounting plate 2043. The two adjustment racks 2042 are opposite to each other and staggered. A rotating gear 2041 is meshed between the two adjustment racks 2042. As the rotating gear 2041 rotates, the two adjustment racks 2042 can move back and forth or relative to each other. A driving motor is provided on the inner side surface of the support plate 203. The driving motor is connected to the rotating gear 2041, and the driving motor can drive the rotating gear 2041 to rotate.

When the width of the steel web 102 needs to be adapted, the drive motor works to drive the rotating gear 2041 to rotate, and the two adjusting racks 2042 meshing with it move back and forth, driving the lateral rail 2011 fixed thereto to move, and the limit rod moves with the lateral rail 2011, and can always provide support for the lateral rail 2011 in the up and down directions. When the welding arm 2013 is located in a suitable welding position, the drive motor stops working and the position of the lateral rail 2011 stops being fixed.

In this embodiment, preferably, a vertical pole 105 is provided between the lower horizontal frame 100 and the upper horizontal frame 101 to support and reinforce the two. Feeding components 300 located on both sides of the steel web 102 are symmetrically provided on the sides of the vertical pole 105. By providing the feeding components 300, multiple steel wing plates 103 can be continuously fed, and the feeding position of the steel wing plates 103 can be limited, and the steel wing plates 103 can maintain a pushing and pressing effect, which is convenient for the steel wing plates 103 to be closely spliced with the steel web 102 and is convenient for welding. The feeding component 300 includes two relatively distributed storage plates 301, both of which are L-shaped, and a gap is left between the inner ends of the two storage plates 301 for the steel web 102 to extend into. In order to facilitate the contact between the steel web 102 and the surface of the steel wing plate 103, a plurality of small steel balls are evenly arranged on the inner surface of the storage plate 301, which can contact the upper and lower surfaces of the steel wing plate 103 to reduce friction resistance. A plurality of steel wing plates 103 are stored inside the two storage plates 301, and a spherical block 302 is arranged on the outer side of each steel wing plate 103. The spherical block 302 can separate adjacent steel wing plates 103 and reduce the friction resistance encountered by the steel wing plates 103 when unloading. At the same time, the upper and lower surfaces of the steel wing plates 103 are contacted and limited with the inner surface of the storage plate 301, and a mounting frame 303 is arranged on the outer side of the vertical rod 105. A feeding cylinder 304 with a pushing material is embedded in the mounting frame 303 to provide stable support for the feeding cylinder 304.

In this embodiment, preferably, the innermost steel wing plate 103 contacts the side of the steel web plate 102, and the outer surface of the storage plate 301 is provided with a fixing column 305 that passes through the inner cross beam 104. The fixing column 305 is screwed with a limiting ring 306 located on the upper and lower surfaces of the inner cross beam 104. The limiting ring 306 can limit the height position of the fixing column 305 and the storage plate 301. At the same time, the size of the steel wing plate 103 stored between the two storage plates 301 is adjustable to adapt to steel wing plates 103 of different widths.

In summary, according to the width of the steel wing plate 103, the limit ring 306 is rotated to change its position, so that the fixed column 305 moves outward, and the distance between the two storage plates 301 is adjusted. When the distance is appropriate, the limit ring 306 is rotated to contact the upper and lower surfaces of the inner cross beam 104, and multiple steel wing plates 103 are stored inside the storage plate 301. The innermost steel wing plate 103 contacts the side of the steel web 102. After the welding of the steel wing plate 103 is completed, the entire steel structure is unloaded. Since the upper and lower surfaces of the steel wing plate 103 contact the inner surface of the storage plate 301 Therefore, after the inner steel wing plate 103 is unloaded, the other steel wing plates 103 will not deflect or fall over. Then the feeding cylinder 304 will work, and the internal piston rod will extend to push the steel wing plate 103 to move inward and contact with the small ball, thereby reducing the friction resistance of the steel wing plate 103. When the outer steel wing plate 103 is located at the innermost side, the feeding cylinder 304 stops working, and the extended piston rod always keeps the steel wing plate 103 in close contact with the steel web 102, thereby facilitating welding at the contact point between the two, thereby realizing automatic and continuous feeding of the steel wing plate 103.

The feeding member 400 includes a storage box 401 located behind the lower cross frame 100. The storage box 401 is U-shaped when viewed from the side. While storing the steel web 102, it can play a guiding and limiting role when feeding the steel web 102. Multiple rows of feeding rollers 402 are arranged inside the storage box 401. The two adjacent rows of feeding rollers 402 are arranged inside the storage box 401. 2, a steel web 102 is stored between the steel web 102, a telescopic push rod can be provided on the outside of the steel web 102, which is convenient for feeding the steel web 102 into between the guide wheels 202 distributed up and down, and the feeding roller 402 can reduce the friction resistance when the steel web 102 is fed, and a frame 403 is provided below the storage box 401, and a feeding cylinder 404 is vertically provided on the inner surface of the frame 403, and the feeding cylinder 404 can adjust the height of the frame 403, and a fixed lug 405 is vertically provided on the surface of the storage box 401, and the internal piston rod of the feeding cylinder 404 is connected to the lower surface of the fixed lug 405.

In summary, multiple steel webs 102 can be stored between two adjacent rows of feeding rollers 402, and the external push rod extends out to act on the end of the uppermost steel web 102, and moves the steel web 102 toward the guide wheel 202 for feeding as the push rod moves. After the feeding is completed, the push rod returns to its original position again, and during the feeding process, the steel web 102 contacts and guides the inner surface of the storage box 401, so that the steel web 102 can be fed stably, and the other end of the steel web 102 gradually contacts the guide wheel 202, and at the same time, the side contacts the inner side of the steel wing plate 103. After the welding of the upper steel web 102 is completed, the loading cylinder 404 works The inner piston rod extends out, driving the material storage box 401 to move upward, allowing the steel web 102 below to move upward to the loading position, making it convenient for the pushing rod to push the steel web 102 here. When the next steel web 102 is loaded, the loaded steel web 102 will push the welded steel web 102 to move backward for unloading. At this time, the lifting cylinder 208 works, and the limit plate 207 moves upward with the operation of the lifting cylinder 208, exposing the side of the storage plate 301, which does not affect the unloading of the welded steel web 102 and the steel wing plate 103. After the loading of the steel web 102 is completed, the unloading of the welded steel web 102 is completed.
