Description

Technical Field

[0001] The invention mainly relates to the technical field of pile foundation cage stirrup welding, and in particular to an automatic welding device for pile foundation cage stirrups. Background Art

[0002] The pile foundation cage stirrups are surrounded by multiple steel bars, and cement or other fillers are poured inside for stable support. For example, the cylindrical pile foundation cage stirrups are bent manually with the help of machines according to the situation, and then welded manually. The operation often requires a large number of people to weld on site, and when welding, if faced with a larger pile foundation cage, it is necessary to overcome the problems of welding height and welding angle. There are also steel cage processing equipment in the prior art, but these equipment can often only process pile foundation cages with cylindrical contours, and lack square welding processing. For example, when producing a square pile foundation cage, the bending and enclosing of the steel bars on all four sides still need to be done manually. Summary of the invention

[0057] In the actual setting of the present invention, the height of the main shell 101, the height of the single feed roller 107, the height of the multiple feed rollers 110, and the distance between the various components can be adaptively set to ensure that there is no interference with each other, ensuring that the bending of the single steel bar 108 and multiple steel bars 111 can be completed smoothly.

[0058] The working principle of the present invention is as follows: six multiple steel bars 111 are respectively inserted into the multi-feed roller 110, and then the multi-feed motor 109 is started to drive the multi-feed roller 110 to rotate. Under the action of the two multi-feed gears 112, the upper and lower multi-feed rollers 110 will rotate together to feed the multiple steel bars 111 into the main body shell 101; after the multiple steel bars 111 enter the main body shell 101 and reach a suitable length, the multi-bending cylinder 123 is started to extend the multi-bending seat 165, and then the multi-bending small cylinder 167 is started to slide the multi-bending main rod 166 and the multi-bending frame 168 horizontally, and each multi-bending guide column 173 is slid to the bottom of each multiple steel bars 111.

[0059] At this time, the feeding of the multiple steel bars 111 is stopped, and the multi-bending motor 169 is started to drive the multi-bending cross bar 171 to rotate, and the multiple steel bars 111 are bent by the multi-bending cross bar 171. After bending, the multi-bending cross bar 171 is reset, and the multiple steel bars 111 continue to be fed. When the feeding reaches the next suitable length, the multi-bending motor 169 is started again to drive the multi-bending cross bar 171 to bend the multiple steel bars 111. This requires three bendings, and each of the multiple steel bars 111 is bent into a square.

[0060] After the bending is completed, the cutting device 114 under the multiple steel bars 111 is started to cut off the six multiple steel bars 111, and then the lifting motor 120 is started to drive the lifting synchronous gear 121 and the lifting synchronous belt 122 to rotate, and the lifting card seat 129 will slide to catch the arrangement of the six multiple steel bars 111, or it can catch the multiple steel bars 111 before cutting the multiple steel bars 111 to support the multiple steel bars 111, and the movable end of the positioning cylinder 184 is started to extend, and the positioning cylinder 184 first pushes the positioning slide frame 179 to slide, and the positioning When the sliding frame 179 slides, the positioning sliding long rod 180, the positioning sliding special-shaped rod 181, and the positioning sliding short rod 190 are used to drive the first clamping claw 188 to slide. The first clamping claw 188 will clamp the multiple steel bars 111, and the positioning sliding frame 179 pushes the positioning first connecting rod 185, the positioning middle rod 186, and the positioning second connecting rod 187 to rotate. The positioning second connecting rod 187 pushes the auxiliary frame 183 to slide, and the auxiliary frame 183 drives the second clamping claw 189 to slide, clamping the multiple steel bars 111 in the vertical direction up and down, and fixing the multiple steel bars 111.

[0061] Then the lifting card seat 129 continues to rise until it approaches the entry position of the single steel bar 108, and then the single steel bar 108 is inserted, and the single feeding motor 105 is started to drive the single feeding roller 107 to rotate, and the single feeding roller 107 feeds the single steel bar 108 in and passes over the outside of the multiple steel bars 111 close to the grabbing support 130. When it reaches a certain length, the single bending cylinder 138 is started to drive the single bending seat 139 to extend, and then the single bending height cylinder 140 is started to drive the single bending front end plate 142 to rise, so that the single steel bar 108 is located on the outside of the single bending guide column 145. At this time Start the single bending motor 143 to drive the single bending column 146 to rotate, bend the single steel bar 108, and surround the bent single steel bar 108 on the sides of the four multiple steel bars 111. Then the single bending column 146 is reset, and the single steel bar 108 continues to be fed. When it reaches a suitable length, it is bent again until it is surrounded on the four sides of the multiple steel bars 111 to form a square. The single steel bar 108 is cut off by the cutting device 114 above the single steel bar 108. After cutting, the single feeding motor 105 drives the remaining single steel bars 108 to retreat a certain distance to avoid interference.

[0062] The welding motor 103 is started to drive the welding fixed block 132 to rotate, and the welding fixed block 132 drives the welding main rod 134 to slide on the welding first rod 136, and the welding first rod 136 will slide on the welding second rod 137, and the disc welding machine 135 is used to weld on the outside of the square pile foundation cage. When the outer periphery of the bottom layer is welded, the lifting card seat 129 is lowered for a distance, and the outer side of the pile foundation cage is surrounded again, and then the disc welding machine 135 is used to weld all around, and the horizontal single steel bar 108 and the vertical multiple steel bars 111 are welded together, and this process is repeated until multiple layers of single steel bars 108 are sequentially surrounded in the horizontal direction of the multiple steel bars 111, and a pile foundation cage is gradually welded. The single steel bar 108 is surrounded on the four horizontal sides, and the multiple steel bars 111 are surrounded on the four vertical sides.

[0063] The lifting card seat 129 is moved to a position higher than the discharge receiving seat 128, and the movable end of the grabbing cylinder 148 is contracted to drive the grabbing long connecting rod 150 and the grabbing support 130 to slide. The grabbing support 130 slides horizontally to approach the pile foundation cage, and then the movable end of the grabbing small cylinder 156 is started to extend, pushing the grabbing slide plate 160 to move. The grabbing slide plate 160 drives the grabbing short connecting rod 159 to rotate under the action of the grabbing fixed column 158. The grabbing short connecting rod 159 pulls the two grabbing small connecting rods 157. The grabbing claws 152 are close to each other, and two of the horizontal single steel bars 108 are clamped by the grabbing claws 152, and the grabbing reversing motor 153 is started to drive the grabbing gear 154 and the grabbing large gear ring 155 to rotate, thereby rotating the grabbing disc 151 by ninety degrees. The grabbing claws 152 on the grabbing disc 151 will drive the formed pile foundation cage to flip and fall on the discharge receiving seat 128, until the pile foundation cage stably falls on the discharge receiving seat 128, then release the grabbing claws 152, and the grabbing support 130 retreats.

[0064] After the discharge socket 128 receives the pile foundation cage, the discharge motor 127 is started to drive the discharge screw 126 to rotate, so that the discharge socket 128 slides toward the main body discharge port 102, and finally the welded pile foundation cage is sent out. The staff checks whether there are any welding defects and performs repair welding to complete it.
