Description

Technical Field

[0001] This invention relates to the field of road construction technology, and specifically to a steel bar welding and fixing device for municipal road construction. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete, and their cross-section is usually circular. During road construction, multiple reinforcing bars need to be welded together to meet usage requirements.

[0003] Reference Figure 1 and Figure 2 ,in, Figure 1 This refers to the steel reinforcement frame component that needs to be welded in this application, and Figure 2 It is a finished triangular steel frame component formed by welding various steel bars and connectors. The steel frame component includes a first steel bar 411, two second steel bars 421, two first connectors 412 and multiple second connectors 422.

[0004] Currently, during the welding process, due to the inconvenience of fixing the reinforcing bars, in order to avoid the contact surfaces of the reinforcing bars easily shifting and causing welding failure, it is usually necessary for multiple people to work together to manually support and position each component, or to use wires, ropes, etc. to wrap and fix the shape of each component, and then welders weld the welding points between each component to form a triangular reinforcing bar frame 4.

[0005] It is evident that the welding process of the triangular steel bar frame 4 involves complex and cumbersome procedures, and has low processing efficiency. It requires a significant investment of manpower and resources, and also consumes a long processing cycle, which is extremely inconvenient. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a steel bar welding and fixing device for municipal road construction, so as to solve the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0009] The first erection component is used to erect two first connectors on the first steel bar respectively, so that the first steel bar and the two first connectors are welded together to form a first steel bar frame;

[0010] The second erection assembly is used to erect two second steel bars together on multiple second connectors, so that the two second steel bars and multiple second connectors are welded together to form a second steel bar frame;

[0011] The third erection component is used to erect the two second reinforcing bars of the second reinforcing bar frame onto the two first connecting members on the first reinforcing bar frame, so that the first reinforcing bar frame and the second reinforcing bar frame are welded together to form a triangular reinforcing bar frame.

[0012] In one embodiment, the first erection component includes:

[0013] First workbench;

[0014] The first shaping mechanism includes a first placement position and two flipping units disposed on the first workbench. The two flipping units are respectively disposed on both sides of the first placement position. The first placement position is used to place the first reinforcing bar. The flipping units are used to place and flip the first connector so that a protruding part on one side of the first connector abuts against the first reinforcing bar located at the first placement position.

[0015] In one embodiment, the flipping unit includes a first driving member and a flipping plate. The first driving member is rotatably connected to the first worktable, and the flipping plate is rotatably connected to the first worktable. The driving end of the first driving member is rotatably connected to the flipping plate, and the first driving member is used to drive the flipping plate to perform a flipping action.

[0016] In one embodiment, the flip plate is provided with a plurality of elastic positioning members, each of which is respectively provided in correspondence with a plurality of protrusions on one side of the first connector. The elastic positioning members are used to position the protrusions on one side of the first connector so that the protrusions on the other side come into contact with the first reinforcing bar. The flip plate is also provided with a first clearance notch, which is provided at the position where the protrusions on the other side of the first connector come into contact with the first reinforcing bar.

[0017] In one embodiment, the first connector has a first side and a second side, and both the first side and the second side of the first connector are provided with a plurality of protrusions, and the plurality of protrusions on the first side of the first connector and the plurality of protrusions on the second side are arranged alternately at intervals.

[0018] Multiple elastic positioning members on the flipping plate of one of the flipping units are correspondingly arranged with multiple protrusions on the first side of one of the first connectors, so that the first reinforcing bar contacts the multiple protrusions on the first side of one of the first connectors to form multiple first welded parts.

[0019] Multiple elastic positioning members on the flip plate of another flip unit are correspondingly arranged with multiple protrusions on the second side of another first connector, so that the first reinforcing bar contacts the multiple protrusions on the second side of another first connector to form multiple second welded parts.

[0020] Multiple first welded portions and multiple second welded portions are respectively arranged alternately along the length direction of the first reinforcing bar.

[0021] In one embodiment, the second erection component includes:

[0022] Second workbench;

[0023] The second shaping mechanism is installed on the second workbench. The second shaping mechanism is provided with multiple first limiting units and multiple second limiting units.

[0025] In one embodiment, the second limiting unit includes two support columns respectively corresponding to the two limiting plates. The top of the support column is provided with an inclined support surface that is inclined toward the corresponding limiting plate. The inclined support surface and the corresponding end of the second connector placed in the limiting groove together form a support part for supporting the second reinforcing bar.

[0026] In one embodiment, the third erection component includes a third workbench, which is provided with a support groove for erecting the second steel bar frame on the first steel bar frame. Multiple second clearance notches are provided at intervals on both sides of the support groove, and the multiple second clearance notches on one side of the support groove correspond one-to-one with multiple contact points on the same side of the first steel bar frame and the second steel bar frame.

[0027] In one embodiment, a limiting groove is provided between the two second clearance notches on the same side. The limiting groove is provided corresponding to one end of the second connector to prevent the second connector of the second steel frame from moving the second steel bar left or right.

[0028] Compared with existing technologies, the beneficial effects of this invention are as follows:

[0029] The first and second erection components are used to orderly overlap and fix the steel reinforcement frames, which facilitates subsequent welding work to form the first and second steel reinforcement frames. No multiple people are required to operate them. Then, the first and second steel reinforcement frames are overlapped again by the third erection component to form a triangular steel reinforcement frame through efficient and stable welding. The standardized operation process ensures the overall welding quality, reduces the non-conforming factors caused by human error, and achieves efficient steel reinforcement welding and fixing without the need for multiple people, which greatly reduces the operating costs.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1 to 17 As shown, the present invention provides a steel bar welding and fixing device for municipal road construction, comprising:

[0050] The first erection assembly is used to erect two first connectors 412 on the first steel bar 411 respectively, so that the first steel bar 411 and the two first connectors 412 are welded together to form a first steel bar frame 41;

[0051] The second erection component is used to erect two second steel bars 421 together on multiple second connectors 422, so that the two second steel bars 421 and multiple second connectors 422 are welded together to form a second steel bar frame 42;

[0052] The third erection component is used to erect the two second steel bars 421 of the second steel bar frame 42 on the two first connectors 412 on the first steel bar frame 41, so that the first steel bar frame 41 and the second steel bar frame 42 are welded together to form a triangular steel bar frame 4.

[0053] In this embodiment, the first and second erection components are used to orderly overlap and fix the steel reinforcement frames, thereby facilitating subsequent welding work to form the first steel reinforcement frame 41 and the second steel reinforcement frame 42. No multiple people are required to operate this way. Then, the first steel reinforcement frame 41 and the second steel reinforcement frame 42 are overlapped again by the third erection component to facilitate efficient and stable welding to form the triangular steel reinforcement frame 4. The standardized operation process ensures the overall welding quality, reduces unqualified factors caused by human error, and achieves efficient steel reinforcement welding and fixing without the need for multiple people, greatly reducing the operating costs.

[0054] like Figure 1-5 , Figure 16-17 As shown, it should be noted that the triangular steel bar frame 4 includes a first steel bar 411, two first connecting pieces 412, two second steel bars 421, and multiple second connecting pieces 422. The first steel bar 411 is connected to the two second steel bars 421 respectively through the two first connecting pieces 412. The two second steel bars 421 are connected to each other through multiple second connecting pieces 422. The first steel bar 411 and the two second steel bars 421 are arranged in a triangle. The first connecting pieces 412 are arranged in a wave shape. The first connecting pieces 412 have multiple protrusions 4121 on both sides. The first connecting pieces 412 are connected to the first steel bar 411 and the second steel bar 421 respectively through the protrusions 4121 on both sides. The two ends of the second connecting pieces 422 have limiting hooks 4221. The second connecting pieces 422 are hooked and connected to the two second steel bars 421 respectively through the limiting hooks 4221 at both ends. By arranging the triangular steel reinforcement frame 4 in a triangular shape, the triangular steel reinforcement frame 4 can provide high strength and strong support for the road, effectively enhancing the road strength and support. The first connecting piece 412 supports and connects the first steel bar 411 and the second steel bar 421, and the two second steel bars 421 are hooked and limited by the limiting hook part 4221 of the second connecting piece 422. Combined with the welding effect, the overall working strength is greatly guaranteed, making it suitable for use in various high-strength roads.

[0055] It is necessary to understand that, such as Figures 6 to 9As shown, two first connectors 412 are respectively erected on the first reinforcing bar 411 by the first erection assembly, forming multiple first welding points and second welding points for welding, so that the first reinforcing bar 411 and the two first connectors 412 are welded together to form a first reinforcing bar frame 41; wherein, the first welding point is formed by one of the first connectors 412 contacting the first reinforcing bar 411, and the second welding point is formed by the other first connector 412 contacting the first reinforcing bar 411, and the multiple first welding points and multiple second welding points are staggered along the length direction of the first reinforcing bar 411; thereby achieving the effect of multi-point support for the first reinforcing bar 411, greatly improving the overall strength, and achieving the effect of rapid erection and fixation, which facilitates rapid welding of the first reinforcing bar 411 and the first connectors 412.

[0056] And, such as Figures 10 to 12 As shown, two second reinforcing bars 421 are jointly erected on multiple second connecting members 422 by a second erection assembly, forming multiple third and fourth welding points for welding, so that the two second reinforcing bars 421 and the multiple second connecting members 422 are welded together to form a second reinforcing bar frame 42; wherein, the third welding point is formed by one of the second reinforcing bars 421 contacting one end of the second connecting member 422, and the fourth welding point is formed by the other second reinforcing bar 421 contacting the other end of the second connecting member 422; this effectively prevents the two second reinforcing bars 421 from detaching from the second connecting members 422, and achieves the effect of rapid erection and fixation, facilitating rapid welding of the second reinforcing bars 421 and the second connecting members 422.

[0057] And, as Figures 13 to 15 As shown, the third erection component is used to erect the two second steel bars 421 of the second steel bar frame 42 onto the two first connectors 412 on the first steel bar frame 41, and to form a plurality of fifth and sixth welding points for welding, so that the first steel bar frame 41 and the second steel bar frame 42 are welded together to form a triangular steel bar frame 4, ensuring the overall strength of the steel bar frame and achieving the effect of rapid erection and fixation, which facilitates the rapid welding and fixation of the second steel bar frame 42 and the first steel bar frame 41.

[0058] like Figures 6 to 9 As shown, in one embodiment, the first erection component includes:

[0059] First workbench 11;

[0060] The first shaping mechanism includes a first placement position 121 and two flipping units 122 disposed on the first workbench 11. The two flipping units 122 are respectively disposed on both sides of the first placement position 121. The first placement position 121 is used to place the first reinforcing bar 411. The flipping unit 122 is used to place and flip the first connecting member 412 so that the protrusion 4121 on one side of the first connecting member 412 abuts against the first reinforcing bar 411 located in the first placement position 121.

[0061] In this embodiment, by setting a first shaping mechanism on the first workbench 11, and by using the first placement position 121 of the first shaping mechanism and the two flipping units 122, the protrusions 4121 on one side of the two first connectors 412 are respectively brought into contact with the first steel bar 411 to form a welding point, which facilitates efficient and stable welding of the welding point by the welding mechanism in the future.

[0062] like Figures 6 to 9 As shown, in one embodiment, the flipping unit 122 includes a first driving member 1221 and a flipping plate 1222. The first driving member 1221 is rotatably connected to the first worktable 11, and the flipping plate 1222 is rotatably connected to the first worktable 11. The driving end of the first driving member 1221 is rotatably connected to the flipping plate 1222. The first driving member 1221 is used to drive the flipping plate 1222 to perform a flipping action.

[0063] In this embodiment, the first driving member 1221 drives the flipping plate 1222, thereby flipping the first connecting member 412 placed on the flipping plate 1222 and placing it on the first reinforcing bar 411. This ensures that during the welding process, the first connecting member 412 always maintains a preset angle of contact with the first reinforcing bar 411, achieving the effect of shaping welding and avoiding situations such as contact surface displacement during the welding process, which could lead to welding failure and substandard welding quality.

[0064] like Figures 6 to 9 As shown, in one embodiment, the flip plate 1222 is provided with a plurality of elastic positioning members 12221, which are respectively provided in correspondence with a plurality of protrusions 4121 on one side of the first connector 412. The elastic positioning members 12221 are used to position the protrusions 4121 on one side of the first connector 412 so that the protrusions 4121 on the other side can contact the first reinforcing bar 411. The flip plate 1222 is also provided with a first clearance notch 12222, which is provided at the position where the protrusions 4121 on the other side of the first connector 412 contacts the first reinforcing bar 41.

[0065] In this embodiment, by providing multiple elastic positioning members 12221 on the flip plate 1222, it is ensured that after flipping, the protrusion 4121 on the side of the first connector 412 close to the first steel bar frame 41 always remains in contact with the first steel bar frame 41 and maintains a preset angle connection with the first steel bar frame 41.

[0066] For implementation details, please refer to [link / reference]. Figure 9 The elastic positioning element 12221 includes a limiting post 12221-1, a tension spring 12221-2, and a positioning post 12221-3. The positioning post 12221-3 is installed on the back of the flip plate 1222. The positioning post 12221-3 is connected to one end of the limiting post 12221-1 through the tension spring 12221-2. The limiting post 12221-1 is rotatably connected to the flip plate 1222. The flip plate 1222 is provided with a through-hole. The end of the limiting post 12221-1 away from the tension spring 12221-2 extends through the through-hole to the surface of the flip plate 1222, so as to position the first... The inner recess of the protrusion 4121 of the connector 412 is used for limiting, thereby ensuring that after the flip plate 1222 is flipped, the protrusion 4121 on the side of the first connector 412 near the first steel bar frame 41 always remains in contact with the first steel bar frame 41 and is connected to the first steel bar frame 41 at a preset angle. After the first steel bar is welded to the first connector 412, the flip plate 1222 is reset. Under the elastic action of the tension spring 12221-2, the first connector 412 is prevented from interfering with the reset work of the flip plate 1222 and the limiting post 12221-1.

[0067] like Figure 5-9 As shown, in one embodiment, the first connector 412 has a first side and a second side. Both the first side and the second side of the first connector 412 are provided with a plurality of protrusions 4121. The plurality of protrusions 4121 on the first side of the first connector 412 and the plurality of protrusions 4121 on the second side are arranged alternately at intervals.

[0068] Multiple elastic positioning members 12221 on the flip plate 1222 of one of the flipping units 122 are correspondingly provided with multiple protrusions 4121 on the first side of one of the first connectors 412, so that the first steel bar 411 contacts the multiple protrusions 4121 on the first side of one of the first connectors 412 to form multiple first welded parts.

[0069] Multiple elastic positioning elements 12221 on the flip plate 1222 of another flipping unit 122 are correspondingly provided with multiple protrusions 4121 on the second side of another first connector 412, so that the first reinforcing bar 411 contacts the multiple protrusions 4121 on the second side of another first connector 412 to form multiple second welded parts.

[0070] Multiple first welded parts and multiple second welded parts are arranged alternately along the length direction of the first reinforcing bar 411.

[0071] In this embodiment, the first connector 412 has a first side and a second side. The protrusions 4121 on the first side and the second side of the first connector 412 are staggered. The first reinforcing bar 411 is welded to the protrusion 4121 on the first side of one of the first connectors 412 and to the protrusion 4121 on the second side of the other first connector 412. The welding points of the two first connectors 412 and the first reinforcing bar 411 are staggered, thereby strengthening the support effect on the first reinforcing bar 411, enhancing the overall strength and stability, and facilitating the rapid welding of the two first connectors 412 and the first reinforcing bar 411 by a welding mechanism.

[0072] like Figures 10 to 12 As shown, in one embodiment, the second erection component includes:

[0073] Second workbench 21;

[0074] The second shaping mechanism is installed on the second workbench 21. The second shaping mechanism is provided with multiple first limiting units and multiple second limiting units. The first limiting units are used to vertically place the second connector 422 to prevent the second connector 422 from tipping over. The second limiting units are configured to provide tilting force for the two second reinforcing bars 421 to be tightly attached to the two inner sides of the multiple second connectors 422 respectively.

[0075] In this embodiment, multiple first limiting units and multiple second limiting units are provided on the second workbench 21. The second connector 422 is placed vertically by the first limiting units to prevent it from tipping over. The second limiting units provide an inclination force to the two second reinforcing bars 421, which are tightly pressed against the inner sides of the multiple second connectors 422. This ensures that the two second reinforcing bars 421 are in contact with the multiple second connectors 422 at the same time and always abut against the second connectors 422, thus ensuring the stability and quality of subsequent welding.

[0076] like Figures 10 to 12 As shown, in one embodiment, the first limiting unit includes two clamping plates 221 and two limiting plates 222. The two clamping plates 221 are arranged opposite to each other, and the two limiting plates 222 are arranged opposite to each other. A limiting groove is formed between the two clamping plates 221 and the two limiting plates 222. The limiting groove is used to vertically place the second connecting member 422 to prevent the second connecting member 422 from tipping over.

[0077] In this embodiment, by setting two clamping plates 221 and two limiting plates 222 to work together, a limiting groove that can accommodate the second connecting member 422 is formed, so that the second connecting member 422 can be set vertically, thereby facilitating the second reinforcing bar 421 to be connected to multiple second connecting members 422 at the same time and welded and fixed.

[0078] like Figures 10 to 12 As shown, in one embodiment, the second limiting unit includes two support columns 231 respectively corresponding to the two limiting plates 222. The top of the support column 231 is provided with an inclined support surface 2311 that is inclined toward the corresponding limiting plate 222. The inclined support surface 2311 and the corresponding end of the second connector 422 placed in the limiting groove together form a support portion for supporting the second reinforcing bar 421.

[0079] In this embodiment, two support columns 231 are set up corresponding to the two limiting plates 222, and the inclined support surface 2311 set on the top of the support column 231 cooperates with the corresponding end of the second connector 422 placed in the limiting groove, thereby forming a support part for supporting the second reinforcing bar 421. While supporting the second reinforcing bar 421, the second reinforcing bar 421 is always in contact with the second connector 422 due to gravity, thus ensuring the stability and welding quality of subsequent welding work.

[0080] like Figures 13 to 15 As shown, in one embodiment, the third erection component includes a third workbench 31. The third workbench 31 is provided with a support groove 311 for erecting the second steel bar frame 42 on the first steel bar frame 41. Multiple second clearance notches 312 are provided at intervals on both sides of the support groove 311. The multiple second clearance notches 312 on one side of the support groove 311 correspond one-to-one with multiple contact points on the same side of the first steel bar frame 41 and the second steel bar frame 42.

[0081] In this embodiment, by setting a support groove 311 on the third workbench 31, the second steel bar frame 42 is erected on the second steel bar frame 42. By setting multiple second clearance notches 312 at intervals on both sides of the support groove 311, and the second clearance notches 312 on the same side correspond one-to-one with the contact parts on the same side of the first steel bar frame 41 and the second steel bar frame 42, so as to facilitate the subsequent welding and fixing of the first steel bar frame 41 and the second steel bar frame 42 through the second clearance notches 312.

[0082] like Figures 13 to 15 As shown, in one embodiment, a limiting groove 313 is provided between the two second clearance notches 312 on the same side. The limiting groove 313 is used to prevent the second connector 422 of the second steel frame 42 from moving the second steel bar 421 left and right.

[0083] In this embodiment, a limiting slot 313 is provided between the two second clearance notches 312 on the same side. The second connector 422 of the second steel frame 42 is limited by the limiting slot 313, thereby realizing the stable erection of the second steel frame 42 on the first steel frame 41, so as to facilitate subsequent welding work.

[0084] like Figures 13 to 15 As shown, in one embodiment, the inner walls on both sides of the support groove 311 are also provided with limiting parts 314. There is a preset angle between the two limiting parts 314. The angle of the preset angle is equal to the angle between the outer surfaces of the two first connecting parts 412 of the first steel frame 41. The support groove 311 limits the two first connecting parts 412 of the first steel frame 41 through the two limiting parts 314, thereby ensuring that it can stably and accurately align and weld with the second steel frame 42.

[0085] The implementation principle is as follows:

[0086] During the fixing process of the first steel bar frame 41, the first connector 412 is placed on the flip plate 1222 of the first erection component, and the first steel bar 411 is placed on the first placement position 121. The first driving component 1221 is controlled to work, so that the flip plate 1222 performs a flipping action, thereby causing the protrusion 4121 of the first connector 412 near the first steel bar 411 to abut against the first steel bar 411. When the flip plate 1222 flips to a preset angle, the first driving component 1221 stops working. At this time, the first connector 412 and the first steel bar 411 can be welded through the first clearance notch 12222 of the flip plate 1222.

[0087] During the fixing process of the second steel bar frame 42, the second connectors 422 are placed in the limiting grooves of the first limiting unit. After placement, one end of the second steel bar 421 is passed through the second connectors 422 on the second workbench 21 and placed on the support column 231. The inclined support surface 2311 at the top of the support column 231 ensures that the second steel bar 421 always abuts against the limiting hook part 4221 of the second connector 422, thus ensuring that the second steel bar 421 and the second connector 422 can be welded efficiently and stably during the welding process.
