Description

Technical Field

[0001] The invention belongs to the field of automatic welding, and in particular relates to automatic welding equipment for supporting steel frames. Background Art

[0002] The Bailey frame is a modular, prefabricated steel bridge structure composed of standardized steel units connected by pins. Its name derives from a design by British engineer Donald Bailey, and it was originally used for rapid military bridge construction. In the 1960s, my country improved it into the "321" highway steel bridge, and later developed higher-load-bearing models such as the HD200. The supporting steel frame of the Bailey frame needs to be welded at a specific height before it can be erected. Existing construction plans mostly use manual welding at high altitudes. Since the protection is often relatively simple, there is a great risk of falling during the welding process. Therefore, an automatic welding equipment for the supporting steel frame is proposed. Summary of the Invention

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0004] In view of the following technical problems in the existing technology: the supporting steel frame of the Bailey frame needs to be welded at a specific height before it can be erected, and the existing construction scheme mostly adopts manual welding at high altitudes. Since the protection is often relatively simple, there is a great risk of falling during the welding process.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: an automatic welding device for a supporting steel frame, comprising a main column and a first connecting rod, wherein one end of the first connecting rod is fixedly connected to a second connecting rod, and the end of the second connecting rod, which is offset from the first connecting rod, is fixedly connected to a movable piece, wherein a long groove is concavely provided on the outer periphery of the main column, and the movable piece is movably connected to the long groove; As an optimal technical solution for automatic welding equipment for supporting steel frames, the bottom of the main column is fixedly connected to a stabilizing platform, and the stabilizing platform is connected to the gravity plate by bolts to make the main column stand vertically; The connecting rod 1 is provided with a welding component; Connecting rod 1, connecting rod 2 and the movable piece are connected end to end to form a stable triangular structure, which enables it to resist external forces without causing major deformation and maintain normal operation.

[0006] As an optimal technical solution for automatic welding equipment for supporting steel frames, an adjusting part 1 is installed on the inner side of the main column, and the adjusting part 1 is connected to the connecting rod 1 and can control the connecting rod 1 to work. The adjusting part 1 includes a threaded column, a first gear and a second gear. The threaded column is screwed to the inner side of the main column, and the end of the movable piece deviating from the connecting rod 1 is fixedly connected to the movable column. The movable column is threaded on the threaded column, and the first gear and the second gear are screwed to the inner cavity of the stabilizing platform. The central axis of the first gear coincides with the threaded column. The lower side of the threaded column is located on the inner side of the stabilizing platform and is connected to the first gear, and the second gear is engaged with the first gear.

[0007] As an optimal technical solution for automatic welding equipment for supporting steel frames, a rotating rod is installed on the top of the second cone, and the rotating rod passes through the stabilizing platform. A hexagonal prism is installed on the head of the rotating rod. The rotating rod can be rotated by controlling the rotation of the hexagonal prism to rotate the rotating rod, thereby rotating the second cone. The second cone drives the first cone to rotate, thereby rotating the threaded column. The rotation of the threaded column can cause the movable column to pull the movable piece to move along the main column. The movable piece constrains the movable column to prevent the movable column from rotating around itself. The movable column uses the movable piece and the connecting rod 2 to pull the connecting rod 1 to move; For example, a hexagonal socket is used to control the rotation of the rotating rod.

[0008] As an optimal technical solution for automatic welding equipment for supporting steel frames, a servo motor is installed on the stabilization platform. The power output end of the servo motor is connected to the rotating rod, so that the rotation of the rotating rod can be accurately controlled remotely, thereby realizing the adjustment of the relative position of the connecting rod and the main column.

[0009] As a preferred technical solution for automatic welding equipment for supporting steel frames, the "Adjustment Component 1" adjusts the relative position of the "Connecting Rod 1" and the "Main Column," facilitating the vertical positioning of the welding components to facilitate welding at different locations on the support frame. This is significantly safer than traditional welding methods that require workers to move to elevated locations. Connecting Rod 1 and the welded components attached to it can also be quickly and easily brought to the surface, facilitating maintenance and component replacement. This significantly improves worker safety and saves on the equipment and labor costs associated with maintaining manual work at height.

[0010] As a preferred technical solution for automatic welding equipment for supporting steel frames, several sealing components are installed on the main column. These sealing components include baffles 1, 2, and an intermediate piece. Baffle 1 is screwed onto the upper edge of the intermediate piece, and baffle 2 is screwed onto the lower edge of the intermediate piece. Both baffles 1 and 2 can swing and fold around the intermediate piece, allowing them to abut against each other after folding. Baffle 2 is connected to baffles 1 on other sealing components via a movable platform, which is movably connected to the inner side of the long groove. One baffle 1 is screwed onto the movable piece, and the bottom baffle 2 is screwed onto the main column.

[0011] When the connecting rod moves upward, the baffles 1 and 2 can be spread out at an angle of 180 degrees, covering the long groove of the main column to prevent water and dust from entering the inner side of the main column.

[0012] After the sealing piece is folded, connecting rod 1 can protrude from one side of the sealing piece, and baffle 1 and baffle 2 are 5 to 12 mm thick, and the total stacking size does not exceed 1200 mm, which is convenient for maintaining welded parts.

[0013] As an optimal technical solution for automatic welding equipment for supporting steel frames, when the connecting rod 1 is downward, the baffle 1 and the baffle 2 are stacked together, and part of the structure protrudes from the main column. When the baffle 1 and the baffle 2 are spread out to cover the long groove, their two sides are movably connected to the inner wall of the long groove to ensure the sealing effect.

[0014] The movable column applies a downward thrust through the movable piece, driving the first baffle to swing and overlap with the second baffle.

[0015] Two elastic plates are installed on the middle plate. The two elastic plates are elastic steel bars arranged in a V shape. The middle part of the outer periphery of the elastic plates is fixedly connected to the middle plate, and both ends of the elastic plates enter the constraint tubes respectively.

[0016] When the movable piece moves downward, the elastic piece squeezes the restraining tube, forcing baffle 1 and baffle 2 to swing downward and fit against the main column.

[0017] The inner wall edge of the long groove of the main column is provided with an elastic foreskin, which is movably connected to the sealing piece and is equipped with a closing piece.

[0018] As an optimal technical solution for automatic welding equipment for supporting steel frames, the closure member includes a closure sheet, an extruded rod, and an adjustment rod. The closure sheet is made of nitrile material and is embedded in the sealing groove together with the extruded rod. The adjusting rod drives the extrusion rod to move through the slope of the tilting table, so that the closing piece presses the sealing piece and the movable table to completely seal the long groove.

[0019] The end of the extrusion rod that deviates from the closing piece is fixedly connected to the gas spring component. One end of the gas spring component is installed on the extrusion rod, and the other end is connected to the closing piece. The sealing pressure is maintained by the expansion and contraction force of the gas spring.

[0020] When the adjusting rod moves upward, the slope of its tilting platform and the slope of the extrusion rod squeeze each other, pushing the closing piece out of the sealing groove and pressing against the sealing piece, so that the long groove is completely closed.

[0021] As an optimal technical solution for automatic welding equipment used to support steel frames, the lifting and lowering of the adjustment rod is controlled by the second adjustment component, which includes an internal thread connection barrel, a ring gear, and a third gear. By rotating the rod, the third gear is driven to engage with the ring gear, driving the internal thread connection barrel to rotate, thereby achieving precise position adjustment of the adjustment rod.

[0022] The beneficial effects of the automatic welding equipment for a supporting steel frame of the present invention are as follows: the relative position of the connecting rod and the main column can be adjusted by the adjusting member, thereby facilitating the control of the welding components to reach different positions in the vertical direction, thereby facilitating welding at different positions of the supporting frame; the problem of traditional workers having to move to high places for welding is avoided, greatly improving construction safety, and the connecting rod and the welding components on the connecting rod can be quickly moved to the ground surface, facilitating maintenance and replacement of components, greatly ensuring personnel safety, and saving labor costs for maintaining workers working at high places and carrying equipment; Through the coordinated action of the sealing member and the closure member, the equipment maintains a specific height of the welding component while working. At the same time, the long groove is spread out and covered by the blocking piece 1 and blocking piece 2. The two sides are movably connected to the inner wall of the long groove to ensure the sealing effect. In many cases, tall welding equipment can only be placed in an outdoor environment. This solution can effectively prevent dust and water, and avoid damage to the electronic components and moving parts inside the main column. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0028] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0029] like Figures 1 to 16 As shown, the present invention provides an automatic welding device for supporting steel frames, comprising a main column 12 and a connecting rod 13. One end of the connecting rod 13 is fixedly connected to a connecting rod 2 132. The end of the connecting rod 2 132, which is offset from the connecting rod 13, is fixedly connected to a movable piece 133. A long groove is concavely provided on the outer periphery of the main column 12, and the movable piece 133 is movably connected to the long groove. The bottom of the main column 12 is fixedly connected to a stabilizing platform 122, which is connected to a gravity plate by bolts, so that the main column 12 stands upright. The connecting rod 13 is provided with a welding component; The connecting rod 1 13 , the connecting rod 2 132 , and the movable piece 133 are connected end to end to form a stable triangular structure, which enables it to resist external forces without causing significant deformation and maintain normal operation.

[0030] An adjusting member 16 is installed on the inner side of the main column 12. The adjusting member 16 is connected to the connecting rod 13 and can control the operation of the connecting rod 13. The adjusting member 16 includes a threaded column 162, a gear 163, and a gear 2 164. The threaded column 162 is screwed to the inner side of the main column 12. The end of the movable piece 133 that deviates from the connecting rod 13 is fixedly connected to the movable column. 134, the movable column 134 is threadedly connected to the threaded column 162, the gear wheel 1 163 and the gear wheel 2 164 are screwed to the inner cavity of the stabilizing platform 122, the central axis of the gear wheel 163 and the threaded column 162 coincide with each other, the lower side of the threaded column 162 is located on the inner side of the stabilizing platform 122 and is connected to the gear wheel 1 163, and the gear wheel 2 164 is engaged with the gear wheel 1 163.

[0031] A rotating rod is installed on the top of the second gear 164, and the rotating rod passes through the stabilizing platform 122. A hexagonal prism is installed on the head of the rotating rod. The rotating rod can be rotated by controlling the rotation of the hexagonal prism to rotate, thereby rotating the second gear 164. The second gear 164 drives the first gear 163 to rotate, thereby rotating the threaded column 162. The rotation of the threaded column 162 can cause the movable column 134 to pull the movable piece 133 to move along the main column 12. The movable piece 133 constrains the movable column 134 to prevent the movable column 134 from rotating around itself. The movable column 134 uses the movable piece 133 and the second connecting rod 132 to pull the connecting rod 13 to move, and the connecting rod 13 moves with the welding parts.

[0032] For example, the rotation of the rotating rod can be controlled by using a hexagonal socket, so that the rotation of the second gear 164 can be controlled manually. The second gear 164 drives the first gear 163 to rotate, thereby rotating the threaded column 162. The rotation of the threaded column 162 can cause the movable column 134 to pull the movable piece 133 to move along the main column 12.

[0033] A servo motor 1 is installed on the stabilizing platform 122, and the power output end of the servo motor 1 is connected to the rotating rod, so that the rotation of the rotating rod can be remotely and accurately controlled, thereby adjusting the relative position of the connecting rod 13 and the main column 12.

[0034] Adjustment member 16 adjusts the relative position of connecting rod 13 and main column 12, allowing the welded components to be positioned vertically at different locations, facilitating welding at various locations on the support frame. This is significantly safer than traditional welding methods that require workers to move to elevated locations. Connecting rod 13 and the welded components attached to it can also be quickly and easily brought to the surface, facilitating maintenance and component replacement. This significantly improves worker safety and saves on the equipment and labor costs associated with maintaining elevated workstations.

[0035] Several sealing members 14 are mounted on the main column 12. The sealing members 14 include a baffle 142, a baffle 2 143, and an intermediate member 144. The upper side of the intermediate member 144 is screwed onto the baffle 142, while the lower side of the intermediate member 144 is screwed onto the baffle 2 143. Both the baffle 142 and the baffle 2 143 can swing and fold around the intermediate member 144. After folding, the baffle 142 and the baffle 2 143 can abut against each other. The baffle 2 143 is connected to the baffle 1 142 on other sealing members 14 via a movable platform 145. The movable platform 145 is movably connected to the inner side of the long groove.

[0036] One of the baffles 142 is screwed to the movable piece 133 , and the bottom baffle 2 143 is screwed to the main column 12 .

[0037] When the connecting rod 13 moves upward, the baffle 1 142 and the baffle 2 143 are spread out at an angle of 180 degrees, covering the long groove of the main column 12 to prevent water and dust from entering the inner side of the main column 12.

[0038] The span of baffle 142 and baffle 2 143 is smaller than the span of connecting rod 2 132. After the sealing member 14 is folded, connecting rod 13 can protrude from one side of the sealing member 14. The thickness of baffle 142 and baffle 2 143 is 5 to 12 mm, and the total stacking size does not exceed 1200 mm, which is convenient for maintaining welding parts.

[0039] During the downward movement of the connecting rod 13, the baffle 142 and the baffle 2 143 are stacked together, and part of the structure protrudes from the main column. When the baffle 142 and the baffle 2 143 are spread out to cover the long groove, their two sides are movably connected to the inner wall of the long groove to ensure the sealing effect.

[0040] The movable column 134 applies a downward thrust through the movable piece 133 , driving the baffle 1 142 to swing and overlap with the baffle 2 143 .

[0041] Two elastic sheets 146 are installed on the middle sheet 144. The two elastic sheets 146 are elastic steel bars arranged in a V shape. The middle part of the outer periphery of the elastic sheet 146 is fixedly connected to the middle sheet 144, and both ends of the elastic sheet 146 enter the restraining tube 1462 respectively.

[0042] When the movable piece 133 moves downward, the elastic piece 146 squeezes the restraining tube 1462, forcing the baffle 1 142 and the baffle 2 143 to swing downward and fit against the main column 12. The restraining tube 1462 is screwed to the side of the baffle 1 142 or the side of the baffle 2 143, and the length of the middle piece 144 is greater than the width of the baffle 1 142.

[0043] The inner edge of the long groove of the main column 12 is provided with an elastic sheath, which is movably connected to the sealing member 14 and is equipped with a closing member 15.

[0044] The sealing member 15 includes a sealing piece 152, an extrusion rod 153, and an adjustment rod 154. The sealing piece 152 is made of nitrile material and is embedded in the sealing groove together with the extrusion rod 153. The adjusting rod 154 drives the extrusion rod 153 to move through the slope of the tilting platform 155, so that the closing piece 152 presses the sealing member 14 and the movable platform 145 to completely seal the long groove.

[0045] One end of the extrusion rod 153 that deviates from the closing piece 152 is fixedly connected to the gas spring component 156. One end of the gas spring component 156 is installed on the extrusion rod 153, and the other end is connected to the closing piece 152. The sealing pressure is maintained by the expansion and contraction force of the gas spring. The sealing component 14 and the closing component 15 work together to enable the equipment to maintain a specific height of the welding component while working. At the same time, the baffle 142 and the baffle 2 143 are used to spread out and shield the long groove, and its two sides are movably connected to the inner wall of the long groove to ensure the sealing effect.

[0046] When the adjusting rod 154 moves upward, the slope of its tilting platform 155 and the slope of the squeezing rod 153 squeeze each other, pushing the closing piece 152 out of the sealing groove and pressing against the sealing member 14, so that the long groove is completely closed.

[0047] The raising and lowering of the adjustment rod 154 is controlled by the second adjustment member 17, which includes an inner thread connection barrel 172, a ring gear 173 and a third gear 174. By rotating the rod, the third gear 174 is driven to engage with the ring gear 173, thereby driving the inner thread connection barrel 172 to rotate, thereby achieving precise position adjustment of the adjustment rod 154.

[0048] The head and tail of the threaded column 162 have some areas without threads, and the head and tail of the threaded column 162 are screwed to the inner side of the main column 12.

[0049] The welding components include a main unit 1, a servo motor 2, a connecting arm 1, a connecting arm 3, and a connecting arm 2, a welding gun 5 is screwed to the upper end of the connecting arm 2, a connecting arm 3 and a connecting arm 2, a connecting arm 4 are screwed to each other, and the main unit 1 is screwed to the top of a connecting rod 13. The connecting rod 13 is provided with a servo motor 2, and the power output end of the servo motor 2 is connected to the connecting arm 3. The translational carrier carries the main column 12 to move and control the welding gun 5 to align with the position to be welded for welding; Motors are installed between the main machine 1 and the connecting rod 13, and between the connecting arm 1 3 and the connecting arm 2 4. An electric cylinder can be installed between the main machine 1 and the servo motor 2 2 to improve the flexibility of the welding parts. Implementation method: The stabilizing platform 122 is assembled onto the translation vehicle through the gravity plate, so that the main column 12 stands upright. The translation vehicle can move the main column 12 horizontally to adjust the position of the welding component to correspond to the welding position. The welding component adjusts its height as the connecting rod 13 rotates due to the threaded column 162, thereby adapting to the welding requirements of different height positions of the support steel frame. In inclement weather, dust and water can cause threaded column 162 to become stuck and rust. When adjustment rod 154 reaches its highest point, the slope of its tilting platform 155 and the slope of the extrusion rod 153 press against each other, pushing closing piece 152 out of the sealing groove and pressing against sealing member 14, completely sealing the long groove. The synergistic effect of sealing member 14 and closing member 15 effectively prevents dust and water in outdoor environments, protecting the main column 12 from damage to the internal electronic components and moving parts. During the welding process, the carrier is translated to adjust the horizontal coordinate position of the welding component, and the servo motor 2, connecting arm 1 3, connecting arm 2 4, and welding gun 5 are rotated to adjust the posture of the welding gun 5 so that the welding gun 5 is aligned with the position where welding is required for welding. The movement of the welding gun 5 is adjusted and coordinated with the lifting equipment of the steel frame to realize automated welding. The main machine 1 rotation and the connecting rod 13 can also rotate relative to each other to expand the degree of freedom of the welding gun 5.

[0050] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
