Description

Technical Field

[0001] The present invention relates to the technical field of steel bar trusses, and in particular to a welding processing device and method for steel bar truss floor decks. Background Art

[0002] Rebar truss floor decking is a composite formwork system that integrates the floor slab's steel bars into trusses in a factory-processed manner and then connected to the base slab. This significantly reduces on-site rebar tying, speeding up construction progress and increasing safety. Furthermore, it ensures uniform rebar spacing and a consistent concrete cover thickness, improving floor construction quality and leading to its widespread adoption in the construction industry.

[0003] Patent application CN117020516A discloses a steel truss floor deck production line, belonging to the field of steel truss technology. The production line includes a frame, a conveying mechanism, a welding frame, welding assemblies, a clamping frame, clamping claws, and a raw material platform. The conveying mechanism is slidably mounted on the frame; the welding frame is mounted on the frame; multiple welding assemblies are provided, each slidably mounted on the welding frame; the clamping frame is slidably mounted on the frame; a moving mechanism for driving the clamping frame is provided on the frame; the clamping claws are slidably mounted at the lower end of the clamping frame; two raw material platforms are symmetrically arranged and slidably mounted on both sides of the frame; and a lifting mechanism for driving the raw material platforms is provided on the frame. This invention enables the steel frame to be quickly placed on the steel plate for welding by the welding mechanism.

[0004] In the above scheme, the steel frame is placed on the steel plate and then transported to the welding position through a transportation device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] like Figures 1 to 11 As shown, a steel bar truss floor deck welding processing device and method includes the following embodiments:

[0043] like Figures 1 to 9As shown, embodiment 1 includes an equipment bracket 1, a transmission device 1001 for conveying is installed inside the equipment bracket 1, and a placement support frame 1002 is fixedly connected to both sides of the equipment bracket 1, and further includes:

[0044] Fixedly connected to the fixing frames 2 on both sides of the top of the equipment bracket 1, a handling component for loading the steel bar truss is provided between the two fixing frames 2;

[0045] A fixed plate 3 is provided on the top of the transmission device 1001, and two supporting side plates 301 are fixedly connected to the bottom of the fixed plate 3. A pushing frame 401 is provided on one side of each of the two supporting side plates 301, and a pushing member for pushing the pushing frame 401 to swing in a circular manner is provided on one side of each of the two supporting side plates 301;

[0046] A welding frame 6 is fixedly connected between one end of the two supporting side plates 301, and lower pressing plates 7 are provided on both sides of the welding frame 6.

[0047] A traction member is provided on one side of each 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 specific implementation, the floor decking is first placed on the transmission device 1001, and then transported to the bottom of the welding frame 6 through the transmission device 1001, and then the steel truss to be welded is grabbed and placed between the two supporting side plates 301 through 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 in the center and push it forward; 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 to be welded, 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 Figures 3 and 4 As shown, in this embodiment: the other ends of the two supporting side plates 301 are fixedly connected to the supporting inclined frames 302, and a plurality of rotating rollers 303 are rotatably connected inside the supporting inclined frames 302. The equipment bracket 1 is rotatably connected to the second screw rod 300, and the second screw rod 300 passes through the fixed plate 3 and is connected to the fixed plate 3 through a ball nut pair. 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 to 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 to the 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 to 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 to pulleys 408, the two pulleys 408 are connected by belt transmission, the top of one of the support plates is fixedly connected to the 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. 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, avoiding the misalignment of the floor deck on the lower pressure plate 101 and the steel truss due to transportation, resulting in the inability to perform precise welding. The steel truss is continuously pushed in steps by the two pushing frames 401 to ensure that the steel truss and the floor deck are in relative motion, and the steel truss is positioned and corrected.

[0054] like Figures 7 and 8As shown, embodiment 2: the traction part includes a rack 801 arranged on one side of the equipment bracket 1, the outer side of the rack 801 is meshed with a gear 802, the inside of the gear 802 is fixedly connected to a transmission rod 804, the transmission rod 804 is rotatably connected to the equipment bracket 1, one end of the transmission rod 804 is fixedly connected to a winding disk 803, the outer side of the winding disk 803 is wrapped and fixedly connected with a second pull rope 809, the bottom of the support side plate 301 is fixedly connected to the 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] When the steel bar truss is in contact with the floor deck, a cold weld may occur. Therefore, when the push frame 401 is away from the steel bar truss, the second rotating plate 406 pulls the rack 801 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 drop through the adjusting member. The bottom of the lower pressure plate 7 presses down the steel bar, so that the steel bar to be welded is fully in contact with the floor deck, and by arranging welding guns 701 on both sides of the lower pressure plate 7, the steel bar and the floor deck are welded by the welding gun 701, thereby ensuring that the steel bar and the floor deck are fully welded.

[0057] In addition, the adjusting part can be rotatably connected to one side of the sliding block 901 by a threaded rod 11. 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 different sizes of the steel trusses, the lower pressure position and welding point of the lower pressure plate 7 can be adjusted.

[0058] like Figure 9 As shown, in this embodiment, a sliding rod 902 is fixedly connected to the inside of 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 end of the fixed frame 9, and the second spring 903 is sleeved on the outside of the sliding rod 902.

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

[0060] As shown in Figure 9, embodiment three: both sides of the fixed frame 9 are fixedly connected with fixed cylinders 10, the interior of 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 pass through 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, a one-way air outlet valve is provided on the outside of the exhaust pipe 104, and a one-way air inlet valve is provided at the bottom of the fixed cylinder 10.

[0061] During 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 fixed 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 gas discharged through the exhaust pipe 104 cleans the welding point 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 replenished 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 outside of the lifting plate 204, the output shaft of the first hydraulic rod 202 is fixedly connected to the connecting plate 203, both ends of the connecting plate 203 are fixedly connected to the supporting cross plate 205, and 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, and 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.

[0063] During specific implementation, a motor is set on the fixed frame 2, and the output shaft of the motor is fixed to the first screw rod 201. The lifting plate 204 is driven to move left and right by the first screw rod 201, and the steel truss is clamped by the clamp 206 on the supporting cross plate 205. The clamp 206 can adopt the existing hydraulic clamp. After clamping, the connecting plate 203 is pushed down by the first hydraulic rod 202, and the lifting plate 204 is driven to move by the first screw rod 201, and the steel truss is placed between the two supporting side plates 301 for positioning.

[0064] A method for welding a steel truss floor deck is also provided, comprising the following steps:

[0065] Step 1: First, the floor deck is placed on the transmission device 1001 and transported to the bottom of the welding frame 6 by the transmission device 1001, waiting for the placement of the steel truss;

[0066] Step 2: Use the transport assembly to grab the steel truss to be welded and place it between the two supporting side plates 301. 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.

[0067] Step 3. When the two pushing frames 401 move away from the steel truss under the action of the pushing member, 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 to be welded, and the steel bars are welded by the welding guns 701 on both sides of the lower pressure plate 7.
