[0047] A traction member is provided on one side of the two supporting side plates 301, one end of the traction member is connected to the sliding block 901, and the other end is connected to the pushing member. When the pushing member moves, the lower pressure plate 7 is pulled down by the traction member, so that the lower pressure plate 7 presses down and fixes the welding part of the steel truss.

[0048] During the specific implementation, the floor decking is first placed on the transmission device 1001, and then transported to the bottom of the welding frame 6 by the transmission device 1001, and then the steel truss to be welded is grabbed and placed between the two supporting side plates 301 by the handling assembly. At this time, the two pushing frames 401 are driven forward by the pushing members between the two supporting side plates 301 to clamp and push the steel truss forward in the center; when the two pushing frames 401 are away from the steel truss under the action of the pushing members, the sliding block 901 is pulled down by the traction member, and then the lower pressure plate 7 is driven down by the adjusting member to press down the steel bars at the location where welding is required, and the steel bars are welded by the welding guns 701 on both sides of the lower pressure plate 7, so as to ensure that the steel bars and the floor decking remain stable and avoid the occurrence of cold welding.

[0049] like Figure 3 to Figure 4 As shown, in this embodiment: the other ends of the two supporting side plates 301 are fixedly connected to the supporting oblique frames 302, and the supporting oblique frames 302 are internally rotatably connected to a plurality of rotating rollers 303, and the equipment bracket 1 is internally rotatably connected to the second screw rod 300, the second screw rod 300 passes through the fixed plate 3 and is connected to the fixed plate 3 by a ball nut pair, and guide rods 601 are fixedly connected on both sides of the welding frame 6, and the two guide rods 601 pass through the equipment bracket 1 and are rotatably connected to the equipment bracket 1.

[0050] During specific implementation, when the steel truss is placed between the two supporting side plates 301 through the handling assembly, and most of the steel truss is placed on the supporting diagonal frame 302, a driving motor is installed on the outside of the equipment bracket 1, and the output shaft of the driving motor is fixedly connected to the second screw rod 300, the second screw rod 300 is rotated to adjust the steel truss on the supporting diagonal frame 302 to the place where it needs to be welded with the floor decking to make it more precise.

[0051] like Figures 5 to 7 As shown, in this embodiment: the pushing member includes two second rotating plates 406 , the tops of the two second rotating plates 406 are fixedly connected to the third hydraulic rods 402 , and the telescopic ends of the two third hydraulic rods 402 are fixedly connected to the pushing frame 401 .

[0052] The pushing member also includes two rotating rods 407, the bottom of the two rotating rods 407 are fixedly connected with the first rotating plate 404, the two first rotating plates 404 are respectively arranged on the top of the two second rotating plates 406, the top of the two second rotating plates 406 are fixedly connected with a rotating shaft 405, the two rotating shafts 405 respectively penetrate the two first rotating plates 404 and are rotatably connected to the first rotating plates 404, one side of the supporting side plate 301 is fixedly connected with two support plates, the two rotating rods 407 respectively penetrate the two support plates and are rotatably connected to the support plates, the outer sides of the two rotating rods 407 are fixedly connected with pulleys 408, the two pulleys 408 are connected by belt transmission, the top of one of the support plates is fixedly connected with a first motor, and the output end of the first motor is fixedly connected to the rotating rod 407.

[0053] During specific implementation, after adjusting to the specified position, by starting the first motor, one of the rotating rods 407 is driven to rotate. Since the two rotating rods 407 are connected by the pulley 408 and the belt transmission, the two rotating rods 407 are synchronously rotated and connected, and the rotating rod 407 drives the fixedly connected first rotating plate 404 to rotate, and the first rotating plate 404 drives the second rotating plate 406 to rotate through the rotating shaft 405, thereby driving the pushing frame 401 to perform a circular reciprocating motion, so that the two pushing frames 401 clamp the steel truss in the center and push it forward, so as to avoid the misalignment of the floor decking on the lower pressure plate 101 and the steel truss due to transportation, resulting in the inability to perform precise welding, and the steel truss is continuously pushed step by step by the two pushing frames 401 to ensure that the steel truss and the floor decking are in relative motion, so as to position and correct the steel truss.

[0054] like Figures 7 and 8As shown, embodiment 2: the traction member includes a rack 801 arranged on one side of the equipment support 1, the outer side of the rack 801 is meshedly connected with a gear 802, the inside of the gear 802 is fixedly connected with a transmission rod 804, the transmission rod 804 is rotatably connected to the equipment support 1, one end of the transmission rod 804 is fixedly connected to a winding drum 803, the outer side of the winding drum 803 is wrapped and fixedly connected with a second pull rope 809, the bottom of the supporting side plate 301 is fixedly connected to a second guide plate 810, the second pull rope 809 passes through the second guide plate 810 and the fixed frame 9 and is fixedly connected to the sliding block 901.

[0055] The traction member also includes a horizontal plate 806 fixedly connected to the outside of the rack 801, a first guide plate 805 fixedly connected to the outside of the supporting side plate 301, a first spring 811 and a first telescopic rod 807 fixedly connected between the first guide plate 805 and the horizontal plate 806, the first spring 811 is sleeved on the outside of the first telescopic rod 807, one end of the rack 801 is fixedly connected to the first pull rope 808, the first pull rope 808 passes through the first guide plate 805 and is fixedly connected to one end of the second rotating plate 406.

[0056] During the specific implementation, it is necessary to weld the outer steel bars of the steel truss to the floor decking during the welding process. Since the welding points between the steel bars and the floor decking are prone to non-contact, cold welding is prone to occur during welding. Therefore, in this solution, when the pushing frame 401 is away from the steel truss, the second rotating plate 406 pulls the rack 801 to move toward the first guide plate 805 through the first pull rope 808. At this time, the first guide plate 805 drives the meshing gear 802 to rotate, and the gear 802 drives the winding disk 803 to rotate through the transmission rod 804. The winding disk 803 pulls the sliding block 901 down through the second pull rope 809 wrapped around the outside, and the sliding block 901 drives the lower pressure plate 7 to descend through the adjusting member. The bottom of the lower pressure plate 7 presses down the steel bars, so that the steel bars to be welded are fully contacted with the floor decking, and welding guns 701 are set on both sides of the lower pressure plate 7. The steel bars and the floor decking are welded by the welding guns 701, thereby ensuring that the steel bars and the floor decking are fully welded.

[0057] And for the adjustment piece, the threaded rod 11 can be rotatably connected to one side of the sliding block 901. The threaded rod 11 passes through the lower pressure plate 7 and is threadedly connected to the lower pressure plate 7. A second telescopic rod 12 is fixedly connected between the lower pressure plate 7 and the sliding block 901. When the threaded rod 11 is rotated according to the steel truss of different sizes, the lower pressure position and welding point of the lower pressure plate 7 can be adjusted.

[0058] like Fig. 9 As shown, in this embodiment, a sliding rod 902 is fixedly connected inside the fixed frame 9, the sliding rod 902 passes through the sliding block 901 and is slidably connected to the sliding block 901, and a second spring 903 is fixedly connected between the sliding block 901 and the top of the fixed frame 9, and the second spring 903 is sleeved on the outside of the sliding rod 902.

[0059] In specific implementation, after welding is completed, the pusher continues to push the push frame 401 to move. At this time, the traction member no longer pulls down the sliding block 901, but pulls the sliding block 901 to rise quickly through the second spring 903, and cooperates with the pusher to weld the next welding point.

[0060] As shown in 9, embodiment three: both sides of the fixed frame 9 are fixedly connected with fixed cylinders 10, the fixed cylinder 10 is slidably connected with a lower pressure plate 101, both sides of the sliding block 901 are fixedly connected with mounting plates 103, the bottoms of the two mounting plates 103 are fixedly connected with fixed rods 102, the two fixed rods 102 respectively penetrate the fixed cylinder 10 and are slidably connected to the fixed cylinder 10, the bottoms of the two fixed cylinders 10 are fixedly connected with exhaust pipes 104, the outside of the exhaust pipe 104 is provided with a one-way air outlet valve, and the bottom of the fixed cylinder 10 is provided with a one-way air inlet valve.

[0061] In specific implementation, when the sliding block 901 descends, the mounting plates 103 fixedly connected on both sides of the sliding block 901 drive the fixedly connected fixing rods 102 to descend, and the fixing rods 102 drive the fixedly connected lower pressure plate 101 to move inside the fixed cylinder 10, and the gas inside the fixed cylinder 10 is discharged through the exhaust pipe 104. Before the welding gun 701 welds, the welding point is cleaned by the gas discharged through the exhaust pipe 104 to prevent dust from affecting the welding quality when the welding gun 701 welds. When the sliding block 901 rises, the lower pressure plate 101 rises, and air is supplemented through the one-way air intake valve.

[0062] The handling assembly includes a lifting plate 204, a first hydraulic rod 202 is fixedly connected to the outer side of the lifting plate 204, an output shaft of the first hydraulic rod 202 is fixedly connected to a connecting plate 203, both ends of the connecting plate 203 are fixedly connected to supporting cross plates 205, a clamp 206 for clamping the steel truss is provided at the bottom of the supporting cross plate 205, a first screw rod 201 is rotatably connected between the two fixed frames 2, the first screw rod 201 passes through the lifting plate 204 and is connected to the lifting plate 204 through a ball nut pair, a support rod is fixedly connected between the two fixed frames 2, the support rod passes through the lifting plate 204 and is slidably connected to the lifting plate 204.

[0066] Step 2: Grab the steel truss to be welded and place it between the two supporting side plates 301 through the handling assembly.
