[0002] In the process of urban renewal and reconstruction, some old buildings need to be reinforced due to aging problems or upgrading. Once the wall roof of the old building has a hole, if it is not reinforced in time, the corner of the hole will become a stress concentration point and is easy to crack under the action of load, leading to continuous expansion of the hole, so it is necessary to reinforce the surrounding steel plate in time.

[0030] Specifically, by setting the fixed frame 4, the inner support 5 and the outer frame 6, when the patch plate 3 is welded to the outer angle steel 2, first, the fixed frame 4 is fixed on both sides of the wall 1, then the inner support 5 and the outer frame 6 are installed on the driving rod 409, the driving rod 409 is rotated by the angle adjusting motor 410, the inner support 5 and the outer frame 6 are synchronously rotated and adjusted, so that the welding gun 8 can weld the patch plate 3 on any side of the hole, and the transverse displacement and the longitudinal displacement of the moving seat 408 ensure that the welding point of the welding gun 8 can be accurately aligned with the joint of the outer angle steel 2 and the patch plate 3. When welding, the welding seat 7 travels along the closed track formed by the inner support 5 and the outer frame 6, and the welding gun 8 will be aligned with the joint and automatically realize the welding process of the joint corner position when passing through the joint position, thereby effectively ensuring the accuracy of the joint welding of the outer angle steel 2 and the patch plate 3 and greatly improving the welding quality.

[0031] As shown in Figure 3 and Figure 4 , the fixed frame 4 is fixedly provided with a handle 401 at both ends, and bolt holes are arranged at four corners of the fixed frame 4. The fixed frame 4 is fixedly installed on the wall surface by bolts. Four side edges of the fixed frame 4 are fixedly provided with sliding rails 402, and sliding seats 403 are slidingly installed on the sliding rails 402.

[0032] Specifically, when installing the fixed frame 4, the worker holds the handle 401 to lift the entire fixed frame 4, carries it to the periphery of the hole of the wall 1, and installs and fixes the fixed frame 4 by locking bolts. Two fixed frames 4 are arranged opposite to each other on both sides of the wall 1, which is convenient for disassembly and assembly.

[0033] As shown in Figure 4 and Figure 5 , a transverse screw pair 404 is arranged between the left and right two sliding seats 403 on one side, and a horizontal sliding rod 407 is fixedly arranged between the left and right two sliding seats 403 on the other side. A longitudinal screw pair 406 is arranged between the upper and lower two sliding seats 403 on one side, and a vertical sliding rod 405 is fixedly arranged between the upper and lower two sliding seats 403 on the other side.

[0034] Specifically, when the welding gun 8 needs to weld different patch plates 3, the transverse screw pair 404 drives the moving seat 408 to move horizontally and linearly along the horizontal sliding rod 407, and the longitudinal screw pair 406 drives the moving seat 408 to move vertically and linearly along the vertical sliding rod 405, so as to adjust the horizontal and vertical positions of the welding gun 8 until the welding gun 8 reaches the specified welding station. The transverse displacement and the longitudinal displacement are carried out independently and do not interfere with each other, and the stability during displacement is ensured by the guiding effect of the sliding rod.

[0035] As shown in Figure 6 and Figure 7 , the inner support 5 is fixedly connected with the outer frame 6 through the connecting plate 501 at both ends, the outer wall of the inner support 5 is provided with a running track 502 for driving the welding seat 7 to run, and the front and rear ends of the inner support 5 are provided with a frame-shaped first groove 503.

[0036] Specifically, the running track 502 serves as the power source for the movement of the welding seat 7, and can drive the welding seat 7 to move along a predetermined route, so that the welding torch 8 automatically tracks the weld at the corner position. In this embodiment, the running track 502 adopts a row of roller tracks, the rollers are in close contact with the welding seat 7, and when the rollers are driven to rotate, the rollers will drive the welding seat 7 to realize continuous circumferential circular motion.

[0037] As shown in Figure 7 , the inner wall of the outer frame 6 is symmetrically embedded with a " " type power contact 601 at both ends, the top of the outer frame 6 is fixedly provided with a power supply 602 at both ends, the two ends of the power contact 601 are electrically connected with the corresponding power supply 602, the front and rear ends of the outer frame 6 are provided with a frame-shaped second groove 603, the top of the outer frame 6 is fixedly provided with a camera 604, and the bottom of the outer frame 6 is fixedly provided with a position sensor 605.

[0038] Specifically, the camera 604 can monitor the welding state of the welding torch 8 in real time, and can collect the weld seam picture after welding, and transmit it to the background to judge the good or bad of the welding quality through the visual analysis system, so as to realize intelligent monitoring and detection of the welding process. When adjusting the horizontal displacement, longitudinal displacement and rotation of the welding torch 8, the position sensor 605 can monitor the distance between the welding torch 8 and the panel 3 in real time, so as to ensure that the welding torch 8 can weld at the best welding distance.

[0039] As shown in Figure 8 and Figure 9 , the welding seat 7 is adaptively installed between the outer wall of the inner support 5 and the inner wall of the outer frame 6, the outer wall around the welding seat 7 is provided with a contact block 701 electrically connected with the welding torch 8, the welding seat 7 is provided with a limiting plate 702 outwardly extending at the front and rear ends, and the first groove 503 and the second groove 603 jointly form a limiting groove for the limiting plate 702 to adaptively slide.

[0040] Specifically, by arranging the first groove 503 and the second groove 603, the limiting plate 702 is always constrained to move in the limiting groove, so as to effectively prevent the welding seat 7 from being detached from the inner support 5, so that the welding seat 7 can always run along the correct route, thereby ensuring the welding accuracy.

[0041] In the embodiment, the moving path of the welding gun 8 along the closed track of the frame is consistent with the outer side edge of the batten 3, and the moving contact path of the contact block 701 and the power contact piece 601 is consistent with the joint of the batten 3 and the outer angle steel 2. By arranging the contact block 701 and the power contact piece 601, when the welding seat 7 travels along the closed track of the frame, the welding gun 8 will pass through the contact area of the batten 3 and the outer angle steel 2 at both ends and the blank area between the outer angle steels 2, when the welding gun 8 passes through the joint of the batten 3 and the outer angle steel 2, the contact block 701 will also be in extrusion contact with the power contact piece 601, at this time the welding gun 8 will also be powered on and start to weld the joint, and can automatically track the joint along the track line, the welding gun 8 moves synchronously with the joint and turns the corner, realizes the tracking welding of the joint, when the welding gun 8 passes through the blank area between the outer angle steels 2 at both ends, the contact block 701 will also be separated from the power contact piece 601, at this time the welding gun 8 will also be powered off and stop running, avoiding miswelding and wrong welding at the non-welding position, so that the welding gun 8 automatically tracks the welding seam in the continuous circulation process, and can realize automatic opening and closing with the joint state, effectively ensuring the welding accuracy.

[0042] As shown in Figure 2 The outer angle steel 2 is provided with a mounting hole 201 penetrating through the inner wall, and the batten 3 is provided with a mounting pin 301 corresponding to the mounting hole 201.

[0043] Specifically, before welding, the batten 3 needs to be pre-positioned, through the cooperation of the mounting pin 301 and the mounting hole 201, the batten 3 can be installed in the specified position on the outer angle steel 2 in advance, and then welded and reinforced by the subsequent welding process.

[0044] The working principle of the present application is as follows: Figures 1-9As shown, in use, the worker holds the handle 401 to lift the entire fixed frame 4, carries it to the periphery of the hole of the wall body 1, and installs and fixes the fixed frame 4 through locking bolts, and then installs the inner support 5 and the outer frame 6 on the driving rod 409, and rotates the driving rod 409 through the angle adjusting motor 410 to synchronously rotate and adjust the inner support 5 and the outer frame 6, so that the welding gun 8 can weld the panel 3 on any side of the hole, and the transverse displacement and the longitudinal displacement of the moving seat 408 ensure that the welding point of the welding gun 8 can be accurately aligned with the joint of the outer angle steel 2 and the panel 3. During welding, the welding seat 7 travels along the closed track formed by the inner support 5 and the outer frame 6, and when the welding gun 8 passes through the joint of the panel 3 and the outer angle steel 2, the contact block 701 also extrudes and contacts the power contact piece 601, at which time the welding gun 8 also operates in power-on mode, starts to weld the joint, and can automatically track the joint along the track line, and the welding gun 8 synchronously moves and turns with the joint to realize tracking welding of the joint. When the welding gun 8 passes through the empty area between the two end outer angle steels 2, the contact block 701 also separates from the power contact piece 601, at which time the welding gun 8 also stops operating in power-off mode, avoids miswelding and wrong welding at a non-welding position, makes the welding gun 8 automatically track the welding seam in the continuous circulation process, and can automatically start and stop with the joint state, effectively ensures welding accuracy. When it is necessary to adjust the welding gun 8 to weld different panels 3, the transverse screw pair 404 drives the moving seat 408 to move in a transverse straight line along the transverse sliding rod 407, and the longitudinal screw pair 406 drives the moving seat 408 to move in a longitudinal straight line along the longitudinal sliding rod 405, so as to adjust the horizontal and height positions of the welding gun 8 until the welding gun 8 reaches the specified welding station. After welding is completed, the inner support 5 and the outer frame 6 are detached from the hole of the wall body 1, and the fixed frames 4 at both ends of the wall body 1 are detached, so as to realize the reinforcing and welding process of the outer angle steel 2 of the hole of the wall body 1.

[0045] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
