The moving plate 220 is limited. The T-shaped plate and the moving plate 220 cannot rotate axially with the lead screw 2312 and can only move axially with the lead screw 2312, thereby adjusting the distance between the two welding heads 500 to adapt to the distance between the two welding points at the same wave crest of the web bar 620 and the lower chord bar 610.

[0046] Specifically, arc-shaped plates 211 are fixed on both sides of the top of the backing plate 210. Two openings 212 are opened on each arc-shaped plate 211.

[0047] Further specific description: The design of the two openings 212 has the function of limiting and arranging the wires at the end of the welding head 500 on the same side and the hose 320 at one end of the air suction pipe 310. In addition, the hose 320 and the wire should have appropriate lengths to meet the movement of the welding head 500 and the air suction pipe 310.

[0051] A second driving assembly 260 is provided on the back plate 210. The second driving assembly 260 is used to drive the back plate 210 to slide horizontally and longitudinally on the dry-type frame 240.

[0052] Further specific description: Through the design of the first driving assembly 250 and the second driving assembly 260, the back plate 210 can be driven to move horizontally and transversely and horizontally and longitudinally respectively, and then the welding head 500 on the back plate 210 can be driven to move horizontally and transversely and horizontally and longitudinally as needed.

[0053] Specifically, the welding machine 400 and the dust suction assembly 330 are both fixed on the dry-type frame 240 and are located on one side of the back plate 210.

[0054] Specifically, the dust suction assembly 330 includes a vacuum cleaner 331.

[0055] Further specific description: The air treatment box 332 treats the adsorbed welding odor and then discharges it, reducing air pollution and effectively ensuring the respiratory health of the staff. For the application of the existing technology, it will not be elaborated here.

[0056] Specifically, the first driving assembly 250 includes a first threaded rod and a first limiting rod. The first threaded rod is rotatably connected above the base 100, and the first limiting rod is fixed above the base 100. The first threaded rod is threadedly connected to the dry formwork 240, and the first limiting rod is slidably connected to the dry formwork 240. There is a first driving member on the first threaded rod.

[0057] On both sides of the top end of the base 100, fixing plates are symmetrically fixed. The first threaded rod is rotatably connected between the fixing plates, the first limiting rod is fixed between the fixing plates, and the first driving member is fixed on the fixing plates.

[0058] Further specifically described: The first driving member adopts a motor. The motor drives the first threaded rod to rotate forward and backward, thereby driving the dry formwork 240 to move horizontally back and forth. It can move horizontally according to the contact position between the web bar 620 and the lower chord bar 610 for multi-point welding.

[0059] Specifically, the second driving assembly 260 includes a second threaded rod and a second limiting rod. A through groove 261 is formed in the dry formwork 240.

[0060] At the bottom end of the backing plate 210, a U-shaped plate 262 is fixed. The horizontal section of the U-shaped plate 262 is slidably connected in the through groove 261.

[0061] Both the second threaded rod and the second limiting rod are arranged inside the through groove 261.

[0062] Further specifically described: The second driving member 263 adopts a motor. The motor is fixed on the dry formwork 240, and the output shaft of the motor is fixedly connected to one end of the second threaded rod. The motor drives the second threaded rod to rotate forward and backward, thereby driving the U-shaped plate 262 and the backing plate 210 to move back and forth. The second limiting rod plays a role in limiting the U-shaped plate 262, enabling the U-shaped plate 262 to move back and forth stably, and thus the U-shaped plate 262 drives the backing plate 210 to move back and forth stably.

[0063] When the multi-point welding and welding equipment for the reinforced truss thin-walled plate in the embodiment of the present application is actually used: According to the distance between two welding points at the same wave crest of the web bar 620 and the lower chord bar 610, adjust the distance between the two welding heads 500. The operation is as follows: Hold the handle of the second power source 2313, the handle drives the lead screw 2312 to rotate, the two moving plates 220 move towards each other, and the moving plates 220 drive the two welding heads 500 to move towards each other to an appropriate distance.

[0064] Then, adjust the height of the welding head 500 according to the heights of the two welding points of the web bar reinforcement 620 and the bottom chord reinforcement 610 at the same peak. The operation is as follows: Start the hydraulic cylinder of the first power source 232. After the free end of the hydraulic cylinder drives the frame plate 231 to move down to a suitable position, the hydraulic cylinder stops working;

[0065] Next, start the motors of the vacuum cleaner 331, the welding machine 400, and the second driving member 263. The motor drives the second threaded rod to rotate. Under the limiting action of the second limiting rod, the U-shaped plate 262 moves forward, driving the welding head 500 to move forward synchronously, and simultaneously welding two points at the contact position of the web bar reinforcement 620 and the bottom chord reinforcement 610 to improve the operation efficiency. After welding, the motor drives the second threaded rod to rotate in the reverse direction, and the welding head 500 resets. At the same time, start the motor of the first driving member. The motor drives the first threaded rod to rotate. Under the limiting action of the first limiting rod, the dry-type frame 240 moves horizontally to the positions of the two welding points at the next peak of the web bar reinforcement 620 and the bottom chord reinforcement 610, and then repeat the above operation to weld the welding points;

[0066] The vacuum cleaner 331 absorbs the air odor during the welding process through the suction pipe 310, enters the air treatment box 332 through the hose 320, and is discharged after treatment, ensuring the respiratory health of the staff and being beneficial to the environmental protection of the surrounding environment.

[0067] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
