Description

Technical Field

[0001] The utility model relates to the field of ladder welding, and more specifically, it relates to a support frame for ladder welding. Background Art

[0002] Ladder welding is a process that requires precise operation and high technology. First, appropriate steel materials need to be prepared, cut and shaped according to the design specifications of the ladder to ensure that the dimensions and shapes of all components are accurate. Then, the welding parts of the steel materials are cleaned and polished to remove surface rust, oil stains and impurities to ensure the welding quality.

[0003] During welding, the ladder is placed on a special support frame for welding, and then it is firmly fixed. After that, normal welding operations can be carried out. However, currently, when the same support frame supports ladders of different sizes, since the support surfaces are at the same height, it will affect the position of the ladder handrails, resulting in difficulty for one support frame to be adapted to two ladders, greatly reducing the practicality of the support frame.

[0004] Therefore, in order to solve the above technical problems, this application proposes a support frame for ladder welding. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a support frame for ladder welding.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A support frame for ladder welding, including a support frame installed on a welding platform. A plurality of support plates perpendicular to the long side thereof are welded at the bottom of the support frame. Both sides of the top end of the support plate are connected to a support table through a rotary fixing component. The support table has two surfaces with different heights, and it is rotated through the rotary fixing component to perform the conversion of the two surfaces. After the surface conversion is completed, the angle of the support table is fixed through the rotary fixing component.

[0007] Preferably, the rotary fixing component includes rotary support blocks fixed on both sides of the top end of the support plate, and a rotary support shaft for supporting the rotation of the support table is installed inside the rotary support block.

[0008] Preferably, insertion slots are opened on both sides above and below the rotary support shaft on the back of the rotary support block, and through slots are also opened on both sides above and below the support table. Plug-in blocks are provided at the opening parts of the through slots. The support table is fixed at an angle by inserting the plug-in blocks through the through slots on the support table and then into the insertion slots on the rotary support block.

[0009] Preferably, the support platform is sleeved on the rotary support shaft and can rotate along the rotary support shaft. A stop block is detachably connected to the head of the rotary support shaft, and the support platform can be replaced to adapt to the welding of ladders of other sizes.

[0010] Preferably, the rotary support block is detachably connected to the support plate by screws, so that it can be replaced when the rotary support block is damaged.

[0011] Preferably, a pressing device is arranged above the support frame. When the ladder is supported by multiple support platforms, the ladder is fixed by pressing its bottom, which is a common fixing method.

[0012] Preferably, a reinforcing rod is fixedly connected to the middle of the support frame, and the bottom surface of the reinforcing rod is tightly attached to the top surface of the support plate, which can improve the connection reliability between the support plate and the support frame.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. The present utility model rotates the support platform through the rotary fixing component, thereby converting the two surfaces of the support platform. After the conversion is completed, the support surfaces on the two support platforms are opposite to support the two sides of the ladder. Immediately afterwards, the angle of the support platform can be fixed through the rotary fixing component, so that the support frame can be replaced back and forth on two platforms with different heights, enabling it to be applicable to the welding of two ladders with different sizes, thus solving the problem that it is difficult for a support frame in the background art to be adapted to two ladders, which greatly reduces the practicality of the support frame.

[0015] 2. The present utility model can remove the stop block, then pull out the support platform from the rotary support shaft, insert another support platform, and install the stop block at the same time to complete the replacement of the support platform, so as to adapt to the welding of ladders of other sizes.

[0016] 3. The present utility model can not only reinforce the support frame through the reinforcing rod, but also tightly attach its top surface to the support plate, and can fix between the support plate and the reinforcing rod here to improve the connection reliability between the support plate and the support frame.

[0023] As Figures 1-4 shown, the present utility model provides a support frame based on ladder welding, including a support frame 1 installed on a welding platform. A plurality of support plates 2 perpendicular to the long side thereof are welded to the bottom of the support frame 1. Both sides of the top end of the support plate 2 are connected to a support platform 4 through a rotating fixing component 3. The support platform 4 has two platforms with different heights. The rotating fixing component 3 is used to rotate it to perform the conversion between the two platforms. After the platform conversion is completed, the angle of the support platform 4 is fixed through the rotating fixing component 3. A pressing device is arranged above the support frame 1. When the ladder is supported by a plurality of support platforms 4, the ladder is fixed by pressing its bottom.

[0024] During use, the support platform 4 is rotated through the rotating fixing component 3, so as to convert the two surfaces of the support platform 4. After the conversion is completed, the support surfaces on the two support platforms 4 are opposite to each other to support both sides of the ladder. Then, the angle of the support platform 4 can be fixed through the rotating fixing component 3. After that, the ladder is placed on the support platform 4 for support, and the ladder is fixed through the pressing device. Finally, welding can be carried out. In this way, the support frame can be replaced back and forth on two platforms with different heights, so that it can be applicable to the welding of two different sizes of ladders.

[0025] The rotating fixing component 3 includes rotating support blocks 31 fixed on both sides of the top end of the support plate 2. A rotating support shaft 32 for supporting the rotation of the support platform 4 is installed inside the rotating support block 31. Insertion slots 34 are opened on the back of the rotating support block 31 on both sides of the rotating support shaft 32. Through slots 35 are also opened on both sides of the support platform 4, and insertion blocks 36 are arranged at the opening parts of the through slots 35.

[0026] That is, rotate the support table 4. The support table 4 rotates along the rotary support shaft 32. After rotating to a suitable position, the insertion block 36 first passes through the through slot 35 on the support table 4 and then inserts into the insertion slot 34 on the rotary support block 31 to fix the angle of the support table 4. On the contrary, pull out the insertion block 36 from the insertion slot 34 and the through slot 35, and then the rotation of the support table 4 can be continued to replace the two table surfaces on the support table 4 again.

[0027] Furthermore, the support table 4 is sleeved on the rotary support shaft 32 and can rotate along the rotary support shaft 32. A stop block 33 is detachably connected to the head of the rotary support shaft 32. That is, the support table 4 (a circular through slot 35 is provided on the support table 4) is sleeved on the rotary support shaft 32, and then the stop block 33 is installed on the head of the rotary support shaft 32 to prevent the support table 4 from detaching from the rotary support shaft 32, and then the normal rotation and fixing operations of the support table 4 can be carried out. Moreover, with such a setting, only by removing the stop block 33, the support table 4 can be pulled out from the rotary support shaft 32, and then another support table 4 can be inserted, and at the same time, the stop block 33 is installed to complete the replacement of the support table 4 (the heights of the table surfaces of the replaced support table 4 and the removed support table 4 are different). In this way, the welding of ladders of other sizes can be adapted. The rotary support block 31 is detachably connected to the support plate 2 by screws. In this way, when the rotary support block 31 is damaged, it can be removed from the support plate 2 for replacement. At the same time, a reinforcing rod 5 is fixedly connected to the middle of the support frame 1, and the bottom surface of the reinforcing rod 5 is tightly attached to the top surface of the support plate 2. The support frame 1 can be reinforced by the reinforcing rod 5, and at the same time, since it is tightly attached to the top surface of the support plate 2, the support plate 2 and the reinforcing rod 5 can be fixed (by welding or screwing) here to improve the connection reliability between the support plate 2 and the support frame 1.
