Description

Technical Field

[0001] The present application relates to the technical field of steel bar truss manufacturing, and in particular to steel bar truss feeding equipment and welding systems. Background Art

[0002] Typically, a steel truss consists of an upper chord, two lower chords located below and on either side of the upper chord, and web members connected to the upper and lower chords at either end, creating a stable triangular structure on the sides of the truss. However, because there is no constraint between the two lower chords, they can experience relative displacement when subjected to excessive lateral pressure from concrete, creating stress within the truss and negatively impacting the strength of the floor slab. Therefore, a crossbeam is welded to the two lower chords, and a vertical beam is welded between the center of the crossbeam and the upper chord to increase the stability of the truss.

[0003] However, currently the horizontal beams and vertical beams are manually taken and placed at the approximate position of the steel truss for manual welding, which is not only inconvenient to operate but also inefficient.

[0051] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present application and are not intended to limit the present application. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions of the present application, not all of the structures.

[0052] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0053] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0054] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0055] To ensure the rigidity of the steel truss, the inventors of this application welded reinforced composite beams to the ends of the steel truss. The reinforced composite beams include a horizontal beam and a vertical beam. The horizontal beam extends transversely and perpendicular to the two lower chord steel bars and connects to the two lower chord steel bars, thereby limiting the distance between the two lower chord steel bars. The vertical beam extends vertically, with one end welded to the end of the upper chord steel bars and the other end welded to the center of the horizontal beam, providing support for the upper chord steel bars. The reinforced beam combination improves the rigidity of the steel truss as a whole, resisting the forces applied by the concrete when the steel truss is poured, and preventing deformation.

[0056] When welding reinforced composite beams, it is necessary to manually adjust the end reinforcement to the position of the horizontal beam extending in the transverse direction, and hold the horizontal beam in the welding position abutting the two lower chord reinforcements before manual welding. Similarly, it is necessary to manually adjust the end reinforcement to the position of the vertical reinforcement, and hold the vertical reinforcement in the welding position abutting the center of the horizontal beam and the end of the upper chord reinforcement before manual welding. This not only has low processing efficiency but also requires a lot of labor costs.

[0057] This embodiment provides a welding system, which includes a steel truss feeding device and a welding robot located on one side of the steel truss feeding device. The steel truss feeding device can not only automatically supply end steel bars, but also automatically grab the end steel bars and adjust the angle of the end steel bars to a horizontal beam or a vertical beam before transporting them to the welding position. The welding robot welds the horizontal bars or vertical bars located at the welding position to the steel truss, thereby realizing fully automated welding of reinforced composite beams and steel trusses, which can not only ensure welding quality, but also ensure welding efficiency and reduce labor costs.

[0058] In some embodiments of this application, please refer to Figure 1 As shown, one possible structure of the steel truss loading equipment is that the steel truss loading equipment includes a conveyor platform 1 and two loading devices 2 located upstream and downstream on the same side of the conveyor platform 1. A plurality of steel trusses are sequentially located on the conveyor platform 1, and the conveyor platform 1 is used to drive the steel trusses to move to different workstations. The transmission platform can be a belt conveyor platform or a roller conveyor platform 1. As long as it can drive the steel trusses to move, this embodiment does not make specific limitations. When the conveyor platform 1 is transporting the steel trusses, when the steel trusses are transported to the first workstation, the steel trusses located upstream will be located at the second workstation. At this time, the conveyor platform 1 will stop transporting, leaving time for the steel trusses to be welded to the vertical beams or horizontal beams, and then continue to transport them to the next workstation. The loading device 2 includes a loading platform assembly 21 and a grabbing assembly 22. Multiple end bars are placed on the loading platform assembly 21 and automatically moved to the grabbing position in sequence. The grabbing assembly 22 can grab the end bars from the grabbing position, adjust the angle of the end bars to the horizontal bars welded to the two lower chord bars, or the vertical bars welded to the upper chord bars, and then deliver them to the welding position. At the welding position, the horizontal bars abut the two lower chord bars, while the vertical bars abut the ends of the upper chord bars and the center of the horizontal bars. This ensures that the welding robot will not have any empty welds during the welding process, ensuring the smooth progress of the welding process.

[0059] For further information, please refer to Figure 1 As shown, in order to facilitate the loading of the end steel bars, in some embodiments of the present application, the loading platform assembly 21 is located between the grabbing assembly 22 and the conveying platform 1. The grabbing assembly 22 can directly send the end steel bars to the welding position after grabbing the end steel bars on the grabbing platform and adjusting the angle of the end steel bars. Compared with the method in which the loading platform assembly 21 is located on one side of the grabbing assembly 22 or on the side of the grabbing assembly away from the conveying platform, the process of rotating the end steel bars with the grabbing assembly 22 for position adjustment after grabbing the end steel bars is omitted.

[0060] Since the vertical reinforcement is welded between the upper chord reinforcement and the transverse reinforcement, the welding order of the reinforced composite beam is to weld the transverse reinforcement first and then the vertical reinforcement. Therefore, the end reinforcement at the upstream welding position is a transverse beam, and the end reinforcement at the downstream welding position is a vertical beam. The end reinforcement at the grabbing position is in a transverse beam state parallel to the conveyor 1. After the upstream grabbing assembly 22 grabs the transverse beam at the grabbing position, it does not need to adjust the angle and can directly drive the transverse beam to the welding position. However, after the downstream grabbing assembly 22 grabs the transverse beam at the grabbing position, it needs to rotate the transverse beam 90° to become a vertical beam and then drive the vertical beam to the welding position.

[0061] In some embodiments of this application, please refer to Figures 2a to 4b As shown, the loading platform assembly 21 includes a hopper 211, a lifting plate 212, and a power member 231, wherein one end of the hopper 211 is a storage end and the other end is a discharge end. The storage end is provided with a storage groove 2111 for accommodating at least one end steel bar, and the discharge end is provided with a discharge groove 2112 that allows the end steel bars to be sequentially detached. The storage groove 2111 and the discharge groove 2112 are connected through a discharge channel. A vertical slide rail 2113 is provided at the opening of the discharge groove, and the lifting plate 212 is slidably set in the slide rail 2113. The upper end of the lifting plate 212 is provided with a storage position 2121 for accommodating the end steel bars. The end steel bars located in the storage groove 2111 can move along the discharge channel to the discharge groove 2112 and detach from the discharge groove 2112 to the storage position 2121. The output end of the power member 231 is connected to the lifting plate 212, and can drive the lifting plate 212 to rise and fall, so that the lifting plate 212 switches between the first position and the second position. When the lifting plate 212 is in the first position, the lifting plate 212 is in a low position, and the receiving position 2121 at the top of the lifting plate 212 abuts the lower edge of the notch of the discharge chute 2112. When the lifting plate 212 is in the second position, the lifting plate 212 is in a high position, and the lifting plate 212 lifts the steel bar truss to the grasping position, at which time the receiving position 2121 is the grasping position. The slide rail 2113 can be two sets of slide rails 2113 arranged opposite to each other at the notch of the discharge chute 2112. The two ends of the lifting plate 212 can be slidably set in the slide rails 2113 on the corresponding side. When the lifting plate 212 drives the end steel bars to move up and down, the slide rails 2113 can also limit the position of the end steel bars, preventing the end steel bars from escaping from the receiving position 2121 at both ends of the lifting plate 212. The accommodating position 2121 may be an arc-shaped groove to limit the position of the end steel bar. The power member 231 may be a lifting motor.

[0062] To facilitate the filling of end reinforcement, please refer to Figures 2a to 4bAs shown, in some embodiments of the present application, the receiving groove 2111 has an upward notch. To prevent the end steel bars from getting stuck when moving along the discharge channel, in some embodiments of the present application, the end steel bars located in the receiving groove 2111 are stacked in sequence in the receiving groove 2111 in a direction parallel to the transfer platform. Therefore, when the end steel bars move along the discharge channel, they will also move in the same manner as the transverse bars, so that they can be accommodated in the accommodating position 2121 when they emerge from the discharge chute 2112.

[0063] Further, in some embodiments of this application, please refer to Figures 1 to 4b As shown, the length of the accommodating groove 2111 in the direction parallel to the conveying platform 1 is adapted to the length of the end steel bars, so that the accommodating groove 2111 can only accommodate one row of end steel bars in a horizontal state, thereby preventing the end steel bars from getting stuck during the movement along the feeding channel.

[0064] In some embodiments of the present application, please refer to FIG. Figure 3 As shown, the discharge channel slopes downward and gradually decreases in height from the receiving groove 2111 to the discharge groove 2112, with the notch of the discharge groove 2112 facing the receiving position 2121. This allows only one end of a rebar to pass through the discharge groove 2112, and the end rebar can be positioned on the receiving position 2121 after being released from the discharge groove 2112. When the lifting plate 212 is in the first position, the notch of the discharge groove 2112 can be blocked, preventing the end rebar from being released from the discharge groove 2112. When the lifting plate 212 is in the second position, the notch of the discharge groove 2112 is exposed, allowing the end rebar to be released from the discharge groove 2112 and positioned on the receiving position 2121.

[0065] In some embodiments of this application, please refer to Figures 2a to 4b As shown, the grabbing assembly 22 includes a bracket 221, a multi-stage conveying member 222, and a clamping member 223, wherein the bracket 221 is arranged on the side of the loading platform assembly 21 away from the conveying platform 1, and the multi-stage conveying member 222 is arranged on the bracket 221. The bracket 221 can provide support for the multi-stage conveying member 222 and the clamping member 223. The clamping member 223 is arranged on the multi-stage conveying member 222, and the multi-stage conveying member 222 can drive the clamping member 223 to move toward the conveying platform 1. The clamping member 223 can clamp the end steel bars on the clamping position and adjust the angle of the end steel bars so that the end steel bars are vertical bars, or do not adjust the angle of the end steel bars so that the end steel bars remain in the horizontal bar state. Whether the angle of the end steel bars needs to be adjusted depends on the state of the steel bars to be welded. For example, the clamping member 223 located upstream of the steel bar truss loading equipment of the present application does not need to change the state of the end steel bars, while the clamping member 223 located downstream needs to change the state of the end steel bars.

[0066] In some embodiments of this application, please refer to Figures 2a to 4bAs shown, the gripping member 223 includes a driving member 2231 and a gripper 2232 disposed at the output end of the driving member 2231. The driving member 2231 can drive the gripper 2232 to rotate, and the gripper 2232 can grasp and release the end of the rebar. The driving member 2231 can be a rotary motor, and the output end of the rotary motor drives the gripper 2232 to rotate. The gripper 2232 can be a pneumatic gripper 2232 or a hydraulic gripper 2232. The gripper 2232 is connected to an air pump or a hydraulic pump, and the gripper 2232 grasps or releases by controlling the air pressure or hydraulic pressure.

[0067] In some embodiments of this application, please refer to Figures 1 to 4b As shown, the multi-stage conveying member 222 includes a first-level conveying member 2221 and a second-level conveying member 2222, wherein the first-level conveying member 2221 is arranged on the bracket 221, the bracket 221 provides supporting force, the second-level conveying member 2222 is arranged at the output end of the first-level conveying member 2221, and the clamping member 223 is arranged at the output end of the second-level conveying member 2222. The second-level conveying member 2222 can drive the driving member 2231 to move toward the conveying platform 1 to the grabbing position, the clamping member 223 can abut against the end steel bar on the grabbing position, and can grab the end steel bar. When the angle of the end steel bar needs to be adjusted, the driving member 2231 drives the gripper 2232 and the end steel bar to rotate 90°, and then the first-level conveying member 2221 drives the second-level conveying member 2222 and the driving member 2231 to move toward the conveying platform 1 to the welding position. If there is no need to adjust the angle of the end steel bars, the first-level conveyor 2221 directly drives the second-level conveyor 2222 and the driving member 2231 to move toward the conveying platform 1 to the welding position. At the welding position, the gripper 2232 can clamp the position of the horizontal or vertical bars, and return to its original position after releasing the horizontal or vertical bars after welding is completed.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
