Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically discloses a node synchronous welding device for a reinforced concrete column frame. Background Art

[0002] A reinforced concrete column frame is a load-bearing structural system formed by rigidly connecting or hinging multiple special steel materials, and its main function is to provide an outer frame for subsequent concrete pouring. Most of the outer shapes of reinforced concrete column frames are columnar structures, and the lightweight and high-strength characteristics of its overall structure can effectively bear horizontal loads and bending moments, forming an overall force system. At the same time, anchor bolts or bent tie pieces are mostly used to connect the joints of different steel materials, so as to improve the stable support capacity at each connection joint within the reinforced concrete column frame. At present, most of the connection joints of reinforced concrete column frames need to be welded; the main purpose is to ensure the integrity, seismic performance and force transmission reliability of the reinforced concrete column frame structure; through welding operations, the seismic capacity of the reinforced concrete column frame can be significantly improved, making the joints have high ductility, thereby reducing the risk of core area damage.

[0003] Currently, most of the sizes of reinforced concrete column frames are 10 - 20 meters. Operators need to rely on lifting work platforms or wear hoisting equipment to manually weld each connection joint of the reinforced concrete column frame. Manual welding operations have various technical limitations and cost risk out-of-control problems; firstly, the production efficiency and quality stability are insufficient. Manual welding depends on the operator to weld point by point, and the speed process is relatively slow, which is easily affected by the physical strength and emotional fluctuations of the operator, resulting in unstable welding quality; secondly, manual welding operations rely heavily on the skill level of the operator, and sufficient training cycles need to be given to the operator. The labor cost accounts for more than 60% of the total welding cost, and the high-temperature electric arc, metal spatter and harmful dust increase the risk of occupational injuries, resulting in a sharp increase in the risk of cost out-of-control. Summary of the Invention

[0027] The working principle of the present invention is as follows: Operators can place the reinforced concrete column frame on the support platform 11, and appropriately adjust the positions of the first locking plate 14 and the second locking plate 15 through the fourth cylinder 40 and the fifth cylinder 41, so that the first arc rings 34 and the second arc rings 35 clamp the bottom end of the reinforced concrete column frame, thereby stably placing the reinforced concrete column frame on the support platform 11. When welding operations are performed on the reinforced concrete column frame, the operators can move the lifting seat 7 carrying the reinforced concrete column frame to the side of the bench 1, and can flexibly adjust the spacing difference between the two telescopic welding torches 6 through the spacing adjustment assembly 5, so that the spacing difference between the two telescopic welding torches 6 is the same as the spacing between adjacent two nodes at different heights and the same axis; specifically: by controlling the piston rod of the second cylinder 514, the first driving rack 511 is driven, and through the transmission cooperation of the first transmission gear 510, the driven rack 512 is moved away from or close to the first driving rack 511, thereby adjusting the arrangement height of the support 513, and thus adjusting the arrangement height of the telescopic welding torch 6.

[0028] By controlling the piston rod of the first cylinder 19, the horizontal position of the loading plate 4 is adjusted so that the two telescopic welding torches 6 are arranged at the same height as two adjacent nodes with different heights and the same axis; and under the drive of the telescopic welding torch 6, the tip of the telescopic welding torch 6 performs welding operations on the two nodes; subsequently, by adjusting the electromagnetic slider 18 on the electric rail 17, the vertical position of the adjusting plate 3 is adjusted, thereby completing the welding operations on all nodes with different heights and the same axis. Finally, by controlling the piston rod of the third cylinder 1002, the second driving rack 1008 drives the second transmission gear 1009 to rotate, thereby causing the support table 11 to rotate, and the telescopic welding torch 6 performs welding operations on other nodes of the remaining reinforced concrete column frames.

[0029] Among them, while the telescopic welding torch 6 performs welding operations on the nodes, by controlling the piston rod of the hydraulic cylinder 709, the arrangement height of the top plate 702 can be adjusted, so that the lifting seat 7 and the electric rail 17 form a linkage cooperation structure, thereby shortening the adjustment time of the vertical height of the telescopic welding torch 6 and accelerating the operation efficiency of the welding operation.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
