[Technical field]
[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic bracket square tube butt welding limiting tool. [Background technology]
[0002] In current photovoltaic power stations, photovoltaic bracket materials often use square tubes as columns. In construction operations, square tube butt welding is a common phenomenon, mainly in the splicing of residual materials and super-long square tube materials. In order to ensure the safety of the power station, the design and relevant specifications require that the butt weld must be straight and the transition must be smooth. Internal and external defects such as misalignment, undercut, and slag inclusion are strictly prohibited. However, in the actual construction process, due to the different skills and proficiency of welders, the welding quality varies, and there are certain safety hazards. [Contents of the utility model]
[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic bracket square tube butt welding limiter to solve the problem that the welding quality is difficult to ensure due to different welder skills and proficiency.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A photovoltaic bracket square tube butt welding limiting tooling comprises a bottom tray and a first square tube limiting portal frame and a second square tube limiting portal frame, wherein the bottom tray is a rectangular structure, the bottom tray is provided with two slide rails extending in the length direction side by side in the width direction and a square tube positioning plane is provided between the two slide rails, the first square tube limiting portal frame and the second square tube limiting portal frame are arranged side by side in the length direction of the bottom tray, and slide blocks are provided at the bottom of both side frames of the first square tube limiting portal frame and the second square tube limiting portal frame, and the slide blocks are slidably matched with the slide rails; the square tube positioning plane is used to horizontally position the ends of the two butt-welded square tubes after butt-welding, the first square tube limiting portal frame is connected to the first square tube for limiting, and the second square tube limiting portal frame is connected to the second square tube for limiting, so that the ends of the two butt-welded square tubes remain butt-welded.
[0006] Preferably, the top frame and both side frames of the first square tube limiting door frame and the second square tube limiting door frame are connected with limiting locking members for limiting the square tubes.
[0007] Preferably, the limiting locking member includes a screw, a limiting plate connected to one end of the screw, and a rotating handle connected to the other end of the screw; the first square tube limiting door frame and the second square tube limiting door frame are provided with threaded holes connected to the screw; and the limiting plate is locked with the surface of the square tube.
[0008] Preferably, the inner sides of the first square tube limiting door frame and the second square tube limiting door frame are provided with V-shaped limiting blocks, and the side frames of the first square tube limiting door frame and the second square tube limiting door frame are provided with limiting grooves, and the two sides of the mouth of the limiting block cooperate with the limiting grooves, and the top frames of the first square tube limiting door frame and the second square tube limiting door frame are threadedly connected with limiting screws, and the limiting screws cooperate with the limiting blocks.
[0009] Preferably, the slide rail is a T-shaped slide rail, and the slider is a T-shaped block.
[0010] Preferably, the first square tube limiting portal frame and the second square tube limiting portal frame are welded together into one piece by multiple sections of profiles.
[0011] Preferably, the bottom tray is an alloy profile.
[0012] The utility model adopts the above technical solution and has the following beneficial effects:
[0013] 1. Two butt-welded square tubes are horizontally positioned on the square tube positioning plane and butt-jointed at the ends. The first square tube limiting gantry and the second square tube limiting gantry are arranged side by side along the length direction of the bottom tray, and the bottom slider is slidably matched with the slide rail on the bottom tray, so that the relative position can be adjusted, so that the first square tube limiting gantry and the second square tube limiting gantry are correspondingly close to the butt ends of the first square tube and the second square tube, which is conducive to limiting the butt ends of the square tubes.
[0014] The first square tube limiting gantry is connected to the first square tube limiting position, and the second square tube limiting gantry is connected to the second square tube limiting position, so that the two butt-welded square tubes can be horizontally positioned on the square tube positioning plane while the ends of the two butt-welded square tubes can be kept butted to avoid misalignment, thereby achieving the alignment of the axes of the two butt-welded square tubes and improving the welding process quality.
[0015] Therefore, compared with the traditional butt welding process, the use of the limiting tooling of the utility model for butt welding of two square tubes can greatly improve the flatness of the butt welding, reduce quality defects such as misalignment and deviation, improve the overall aesthetics of the power station, and reduce the safety hazards of the bracket.
[0016] 2. Since the top frame and both side frames of the first square tube limiting door frame and the second square tube limiting door frame are connected with limiting locking parts for limiting the square tube, the limiting locking parts connected to the two side frames can realize limiting locking in the width direction of the square tube, so that the square tube is located in the middle position of the width of the square tube positioning plane, and the limiting locking parts connected to the top frame can further increase the reliability of the positioning of the square tube on the square tube positioning plane, avoid upward movement, thereby ensuring that the axes of the two butt-welded square tubes are aligned.
[0017] 3. Rotate the handle to drive the screw to rotate. After the screw rotates, due to the effect of the threaded hole, the screw moves axially, so that the limit plate and the surface of the square tube are locked together, which is not only convenient for locking, but also convenient for loosening the square tube after welding is completed.
[0018] 4. The V-shaped limit block is used. Since both sides of the mouth of the limit block cooperate with the limit grooves, when the limit screws threadedly connected to the top frames of the first square tube limit door frame and the second square tube limit door frame are rotated, the limit block can only be moved up and down, and after moving downward, the square tube is located in the middle of the width of the square tube positioning plane and the square tube is pressed downward and fixed on the square tube positioning plane.
[0019] 5. Since the slide rail is a T-shaped slide rail and the slider is a T-shaped block, the slider slides along the length direction of the slide rail and is not easy to fall out.
[0020] 6. The first square tube limiting door frame and the second square tube limiting door frame are welded together by multiple sections of profiles, so it is convenient to process and reduce costs. Since the bottom tray is an alloy profile, it is convenient to reduce costs.
[0021] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0031] Embodiment 1
[0032] Reference Figure 1 and Figure 2 As shown, a photovoltaic bracket square tube butt welding limiting tool is used to limit the ends of two butt-jointed square tubes after they are butt-joined to facilitate welding, including a bottom tray 1 and a limiting gantry 2 with an inverted U-shaped structure, a first square tube limiting gantry 2A and a second square tube limiting gantry 2B are provided corresponding to the two butt-welded square tubes 100, the bottom tray 1 is a rectangular structure, the bottom tray 1 is provided with two slide rails 11 extending in the length direction side by side in the width direction and a square tube positioning plane 12 is provided between the two slide rails 11, the first square tube limiting gantry 2A and the second square tube limiting gantry 2B are provided side by side in the length direction of the bottom tray 1, and the two have the same structure. Sliders 21 are provided at the bottom of both side frames of the first square tube limiting gantry 2A and the second square tube limiting gantry 2B, and the sliders 21 are slidably matched with the slide rails 11. The two butt-welded square tubes are positioned on the square tube positioning plane and the ends are butted. The first square tube limiting gantry 2A is connected to the first square tube in a limiting manner, and the second square tube limiting gantry 2B is connected to the second square tube in a limiting manner, so that the ends of the two butt-welded square tubes remain butt-jointed.
[0033] According to the above technical scheme, since the two butt-welded square tubes are horizontally positioned on the square tube positioning plane and the ends are butted, the first square tube limiting door frame and the second square tube limiting door frame slide in cooperation with the slide rail on the bottom tray through the bottom slider, so that the relative positions can be adjusted, so that the first square tube limiting door frame and the second square tube limiting door frame are correspondingly close to the butt ends of the first square tube and the second square tube, which is beneficial to limit the butt ends of the square tubes.
[0034] In addition, the first square tube limiting gantry is connected to the first square tube limiting position, and the second square tube limiting gantry is connected to the second square tube limiting position, so that while the two butt-welded square tubes are horizontally positioned on the square tube positioning plane, the ends of the two butt-welded square tubes are kept butt-jointed to avoid misalignment, thereby achieving the alignment of the axes of the two butt-welded square tubes and improving the welding process quality.
[0035] Therefore, compared with the traditional butt welding process, the use of the limiting tooling of the utility model for butt welding of two square tubes can greatly improve the flatness of the butt welding, reduce quality defects such as misalignment and deviation, improve the overall aesthetics of the power station, and reduce the safety hazards of the bracket.
[0036] The top frame and the side frames of the first square tube limiting door frame 2A and the second square tube limiting door frame 2B are both connected with the limiting locking members 3 for limiting the square tube. Therefore, the limiting locking members connected to the side frames can realize the limiting locking in the width direction of the square tube, so that the square tube is located in the middle of the width of the square tube positioning plane, and the limiting locking members connected to the top frame can further increase the reliability of the square tube positioning on the square tube positioning plane, avoid upward movement, and thus ensure that the axes of the two butt-welded square tubes are aligned.
[0037] Specifically, the position-limiting locking member 3 includes a screw 31, a position-limiting plate 32 connected to one end of the screw, and a rotating handle 33 connected to the other end of the screw. The first square tube position-limiting door frame 2A and the second square tube position-limiting door frame 2B are provided with threaded holes connected to the screw, and the position-limiting plate is locked and matched with the surface of the square tube. The rotating handle drives the screw to rotate. After the screw rotates, the screw moves axially due to the effect of the threaded hole, so that the position-limiting plate is locked and matched with the surface of the square tube, which is not only convenient for locking, but also convenient for loosening the square tube after welding is completed.
[0038] In this embodiment, the slide rail 11 is a T-shaped slide rail, and the slider 21 is a T-shaped block. The two are in T-shaped cooperation, so the slider slides along the length direction of the slide rail and is not easy to fall out. It is understandable that it can also be replaced with a dovetail or other shaped structure.
[0039] In addition, the first square tube limiting door frame 2A and the second square tube limiting door frame 2B are welded together by multiple sections of profiles, such as square steel tubes. The bottom tray is an alloy profile, such as aluminum alloy. They are all conventional materials, which is convenient for reducing procurement costs and processing costs.
[0040] Embodiment 2
[0041] As another embodiment, the inner sides of the first square tube limiting door frame and the second square tube limiting door frame are provided with a V-shaped limiting block, the V-shaped limiting block opening faces downward, the side frames of the first square tube limiting door frame and the second square tube limiting door frame are provided with limiting grooves extending up and down, the two sides of the mouth of the limiting block cooperate with the limiting grooves, so that the limiting block can only slide up and down but cannot rotate, and the top frames of the first square tube limiting door frame and the second square tube limiting door frame are threadedly connected with limiting screws, and the limiting screws cooperate with the limiting block, specifically, they can rotate and cooperate. Therefore, when the limiting screws threadedly connected to the top frames of the first square tube limiting door frame and the second square tube limiting door frame rotate, the limiting block can only move up and down, and after moving downward, the square tube is simultaneously located in the middle of the width of the square tube positioning plane and the square tube is pressed downward and fixed on the square tube positioning plane. Compared with the first embodiment, only one limiting block needs to be set to limit the width of both sides and the upper side of the square tube at the same time.
[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
