The utility model provides a throw material device for longmen submerged arc welding machine at the during operation, at first opens control valve 5, and the welding flux passes through solder flux hose 2 and falls down to the welding seam of work piece from welding agent box 1, and wherein gun tube 3 is located solder flux hose 2's upper reaches, and along with the activity of portal frame this moment, solder flux hose 2 and gun tube 3 move together, also weld the work piece simultaneously. After a welding seam of a workpiece is welded, closing the control valve 5, rotating or moving the workpiece, so that a position to be welded at a second position on the workpiece is positioned under the welding gun tube 3, then rotating the supporting transverse plate 4, and after the supporting transverse plate 4 rotates 180 degrees, fixing the angle of the supporting transverse plate 4 through the fixing mechanism, wherein the welding flux hose 2 also rotates 180 degrees (because the welding flux hose 2 is of a soft structure, the welding flux hose 2 can deform to a certain extent in the rotating process of the supporting transverse plate 4, but the welding flux hose 2 cannot be damaged); after the position of the workpiece has been set, the gantry is moved in the opposite direction, in which case the gun tube 3 is already upstream of the solder hose 2, so that the welding can be carried out normally. Because the gantry frame can weld the workpiece in the back-and-forth process, the gantry frame and the arm body can be prevented from idle running, useless energy consumption is reduced, and the energy-saving performance is good.

When the angle of the supporting transverse plate 4 is adjusted, firstly, the sliding plate 7 slides upwards, and the fixing rod 8 is separated from the fixing hole 9, at this time, the supporting transverse plate 4 is not limited by the horizontal direction, and therefore can normally rotate, after the rotating to a proper angle, the sliding plate 7 is moved downwards, and the fixing rod 8 passes through the fixing hole 9, wherein the sliding prism 6 is polygonal, and is preferably hexagonal prism in the embodiment, so that the sliding plate 7 cannot rotate relative to the sliding prism 6, and the fixing rod 8 can only lift and cannot rotate in the horizontal direction, and after the fixing rod 8 passes through the fixing hole 9, the angle of the supporting transverse plate 4 can be fixed, and in order to facilitate the fixing rod 8 to pass through the fixing hole 9, the bottom end of the fixing rod 8 is arranged to be dome-shaped. When two dead levers 8 are fixed the fixed orifices 9 simultaneously, can reduce the burden of single dead lever 8, also can improve the positional stability who supports diaphragm 4 simultaneously.

During welding, the welding flux falls into a welding seam through the welding flux pipe 10 and the blanking part 11 after falling out of the welding flux box 1; wherein, the welding flux can stably fall into the welding seam because the welding flux tube 10 and the blanking part 11 are always kept in a vertical state, and the welding flux tube 10 and the blanking part 11 are both in a hard structure, thereby preventing the welding flux from deforming when the welding flux falls down too fast and causing the welding flux to fall too far, and the welding flux tube 10 and the blanking part 11 improve the falling quality of the welding flux.

Furthermore, since the width of the slit differs between workpieces, the width of the flux required to drop differs (too large flux tube 10 discharges too much flux and the recovery effect is poor), and in this case, different blanking members 11 can be connected to the bottom end of the flux tube 10. Wherein the connecting portion 11a portion of the blanking member 11 can be screwed with the flux tube 10, so that the detachment and attachment between the blanking member 11 and the flux tube 10 are simple. After the blanking part 11 is connected to the flux tube 10, the actual blanking opening is the cross-sectional area of the blanking part 11b, so that the blanking parts 11b with different diameters can be selected according to the actual size of the gap, and the flux can fall into the gap with high quality (not only can the gap be filled, but also excessive flux is not discharged). The blanking member 11 may also be a straight cylinder to reduce the blanking height of the flux tube 10 and prevent the flux from bouncing off.

During operation, the flux tube 10 and the second transfer tube 14 are located at two ends of the gun tube 3, and the gun tube 3 is located on a connecting line between the bottom end of the flux tube 10 and two ends of the second transfer tube 14. The recycling pipe 12 is externally connected with a suction fan and other structures for generating negative pressure in the recycling pipe 12 and generating negative pressure in the first transfer pipe 13 and the second transfer pipe 14 for sucking away redundant welding flux for recycling. After the flux hose 2 and the flux tube 10 rotate by 180 degrees, the first transfer tube 13 is firstly rotated to a certain angle, then the second transfer tube 14 is rotated to a certain angle, and finally the connecting line between the bottom end of the second transfer tube 14 and the bottom end of the flux tube 10 passes through the gun tube 3 again, so that when the gantry is welded backwards, the second transfer tube 14, the first transfer tube 13 and the recovery tube 12 can be subjected to recovery welding again.

When the first transfer pipe 13 is rotated, the first locking pin 17 is firstly lifted upwards, the first locking pin 17 is separated from the second movable sleeve 16, at this time, the first transfer pipe 13 can be rotated until the first transfer pipe 13 rotates to enable the other second movable sleeve 16 to be positioned right below the first movable sleeve 15, the first locking pin 17 is moved downwards, the first locking pin 17 penetrates through the first movable sleeve 15 and the second movable sleeve 16 simultaneously again, and therefore the rotation of the first transfer pipe 13 can be guaranteed. The angle of the second transfer tube 14 can be fixed to the first transfer tube 13 by operating the second locking pin 20, the third movable sleeve 18 and the fourth movable sleeve 19 in the same manner. Wherein the recovery pipe 12, the first transfer pipe 13 and the second transfer pipe 14 are all made of hard materials which can endure certain high temperature, so that the absorption of the welding machine can be normally carried out.

In addition to the above structures, other parts of the gantry welding machine should be understood as conventional structures, that is, in the structures of the track for supporting the movement of the gantry, the gantry frame body, the welding arm connected to the gantry frame body, the wire reel 22 on the welding arm, the wire feeding wheel 23, and the like, the connection relationship and the working principle between the structures should be understood as conventional technical means, and can be implemented, so that no further description is provided herein.

Example 2

The feeding device for the gantry submerged arc welding machine is different from the first embodiment in that the feeding device further comprises an elastic temperature-resistant pipe which is arranged on the side portion of the welding gun pipe 3 in a C shape, the middle portion of the supporting transverse plate 4 is rotatably connected with the welding gun pipe 3, and the elastic temperature-resistant pipe and the welding flux hose 2 are connected to two ends of the supporting transverse plate 4.

Wherein elasticity temperature resistant pipe is made by the temperature resistant material that has the line deformation, for example high temperature resistant rubber or high temperature resistant bellows etc. when adjusting the angle of elasticity temperature resistant pipe like this, because elasticity temperature resistant pipe can take place deformation to only need rotate support diaphragm 4 and can drive elasticity temperature resistant pipe and move together, and when will supporting diaphragm 4 and rotate 180, solder flux pipe 10 and elasticity temperature resistant pipe can both rotate 180, the operation of adjusting solder flux pipe 10 and elasticity temperature resistant pipe angle is convenient and fast more and more quick.
