Description

Technical Field

[0001] This invention belongs to the field of steel column welding technology, and specifically relates to a tool-type steel column rotating device. Background Technology

[0002] Steel column welding is a common process in industrial manufacturing and construction, currently mainly employing two methods: automatic welding and manual welding. Automatic welding can improve production efficiency, but requires more sophisticated equipment and processes; manual welding is flexible and convenient, suitable for welding in various positions, but demands higher welder skills. Depending on the structure and location of the steel column, different welding positions can be selected, such as flat welding, vertical welding, overhead welding, or downward welding. Choosing the appropriate welding position is crucial for ensuring welding quality and efficiency. A reasonable welding sequence can reduce welding deformation and residual stress, improving the overall stability of the steel column. Based on the material and performance requirements of the steel column, selecting suitable filler material can improve welding quality and prevent welding defects such as cracks and porosity.

[0003] In some situations, manual welding may be dominant. This not only requires a high level of welding skill, but the placement of the steel column also significantly impacts the welding outcome. The steel columns being welded are long and heavy, and after welding one side, they need to be rotated for further welding. This requires either the welder to change angles or the steel column to be flipped. While the welder can still weld by actively moving the column, the change of position makes it awkward and inconvenient, making welding difficult and uncomfortable. Flipping the steel column, on the other hand, allows for finding a better angle and easier adjustment of the welding position, but the heavy steel column is difficult to flip, and the flipping process can easily damage already welded areas.

[0004] In order to improve the first-pass yield rate of steel column processing and welding, and to avoid difficulties in welding operations and thus affect welding quality due to the limitations of the steel column placement position, the present invention provides a tool to assist in the rotation of steel columns. Summary of the Invention

[0005] To address the problem that steel columns are heavy and difficult to rotate, this invention provides a tool-type steel column rotating device that can rotate the steel column in real time during the lap welding process, ensuring that the welding part is in the optimal welding environment.

[0006] The solution adopted by this invention to solve its technical problem is: a tool-type steel column rotating device, including a base and a clamp. The base includes a track, a spiral adjusting rod, a slider, a wheel seat, and a friction rotating wheel. A spiral adjusting rod is installed in the middle of the track, and a slider is fitted on the spiral adjusting rod. The spiral adjusting rod is symmetrically arranged with opposite rotation directions of external threads, and sliders are fitted on the opposite rotation directions of the external threads. The sliders are provided with internal threads. The rotation of the spiral adjusting rod drives the sliders on both sides to move towards or away from each other along the track direction. The track is composed of two parallel I-beams, with the spiral adjusting rod installed in the middle of the I-beams. The sliders installed on the spiral adjusting rod are located between the I-beams, and the wheel seat installed on the slider is located above the I-beams, with the ground of the wheel seat close to the upper surface of the I-beam.

[0007] Each slider is fixed with a wheel seat, through which a friction rotating wheel is mounted. The friction rotating wheel is connected to a motor. An electrical box is mounted on the side of the track, through which the motor is powered and its start and stop are controlled. The clamp has an outer circle and an inner square structure, including a circular outer shell. The circular outer shell is placed between two friction rotating wheels, which support the clamp. A square hole is set in the center of the circular outer shell, and a square steel column is fitted into the square hole for clamping. The circular outer shell includes a bottom groove and a fastening cover. A directional groove is set in the middle of the bottom groove. The fastening cover is installed on the bottom groove to close the groove and form a square hole. After the bottom groove and the fastening cover are fastened together, a circular outer shell is formed. The surface of the circular outer shell is provided with anti-slip texture.

[0008] Furthermore, one end of the snap-fit ​​cover is hinged to the upper end of the side of the bottom groove, and the other end of the snap-fit ​​cover is provided with a buckle, which is snapped to the upper end of the corresponding side of the bottom groove.

[0009] Top plates are installed on the four side walls of the square hole. A telescopic rod is fixed to the rear of the top plate. The telescopic rod has external threads and a worm gear with internal threads is fitted on it. The worm gear meshes with a worm, one end of which extends outward and protrudes from the side of the fixture. A drive sprocket is installed on the protruding end of the worm. The worm gear and the worm are installed in the fixture housing corresponding to the side wall of the square hole. A chain connects the four drive sprockets, which causes the four worms to rotate synchronously, thereby causing the four top plates to move synchronously. Tension sprockets are also provided on the circular housings corresponding to the four corners of the square hole. The chain passes around all the drive sprockets and tension sprockets.

[0010] The top plate is also provided with guide posts, and the circular outer shell is provided with corresponding guide holes. The guide posts are located next to the telescopic rod and are parallel to the telescopic rod.

[0011] Furthermore, a storage basket is provided on the top plate corresponding to the horizontal direction. An airbag is installed in the storage basket. An air inlet is provided on the side of the storage basket. An air inlet pipe is connected to the air inlet. A valve is provided on the air inlet pipe. The airbag expands or contracts by inflating or deflating the airbag through the air inlet pipe.

[0012] The beneficial effects of this invention are as follows: The tool-type steel column rotating device provided by this invention can rotate the steel column in real time during the steel column lap welding process, ensuring that the worker is in the best position to perform the work, ensuring the welding quality of each section, improving the first-pass yield rate of welding, and the steel column can be welded within the rotating device. It is highly operable, safe and reliable, and avoids the problem of unfavorable positions or blind welding caused by the limitation of the steel column placement position, which would make the welding operation difficult and affect the welding quality.

[0013] The tool-type steel column rotation device of this invention places the steel column within a matching outer-circle, inner-square clamp, securing it firmly. A rotating wheel drives the clamp to rotate, thus mechanizing the rotation of the steel column. This provides the welder with the most advantageous welding working surface in real time, ensuring welding quality. This device achieves the goal of free rotation for steel column welding, allowing welding to be performed in the most comfortable position, guaranteeing welding quality. It can be widely used in the welding and processing of steel columns and other components in steel structure construction. Compared with traditional steel column welding, it not only improves welding quality, but also allows for mechanized continuous operation, reducing the overall manufacturing cycle of steel structure components, achieving high-quality results in one go. The operation is simple, efficient, economical, safe, and practical.

[0014] The components of the tool-type steel column rotation device of the present invention are made of high-performance materials, and are simple, convenient and quick to operate; the component connections adopt flexible connections to achieve the effect of detachable assembly; compared with traditional welding methods, it is more convenient, more practical and safer.

Detailed Implementation

[0022] Example 1: As Figure 1 As shown, in order to ensure that the clamped steel column 3 can be balanced, two parallel tool-type steel column rotating devices are used to clamp the two ends of the steel column 3 respectively, suspending and fixing the steel column in the air, which facilitates the subsequent rotating operation.

[0023] like Figure 2 As shown, the tool-type steel column rotating device includes a base 1 and a clamp 2. The base 1 includes a track, a spiral adjusting rod 102, a slider 103, a wheel seat 104, and a friction rotating wheel 105. The spiral adjusting rod 102 is installed in the middle of the track, and the slider 103 is mounted on the spiral adjusting rod 102. The spiral adjusting rod 102 is symmetrically arranged with external threads in opposite directions of rotation, and sliders 103 are mounted on the external threads in opposite directions of rotation. The sliders 103 are provided with internal threads. The rotation of the spiral adjusting rod 102 drives the sliders 103 on both sides to move towards or away from each other along the track direction.

[0024] The track is composed of two parallel I-beams 101. A spiral adjusting rod 102 is installed in the middle of the I-beams 101. A slider 103 installed on the spiral adjusting rod 102 is located between the I-beams 101. A wheel seat 104 installed on the slider 103 is located above the I-beams 101. The ground of the wheel seat 104 is close to the upper surface of the I-beams 101.

[0025] like Figure 4 As shown, each slider 103 is fixed with a wheel seat 104, and a friction rotating wheel 105 is installed through the wheel seat 104. The friction rotating wheel 105 is connected to a motor 106. An electrical box 4 is installed on the side of the track. The electrical box 4 powers the motor 106 and controls the motor 106 to start and stop.

[0026] Carrier plates are welded and fixed at both ends of the track formed by the I-beam 101. Mounting holes are set on the carrier plates and bearings are installed in the mounting holes. The two ends of the spiral adjusting rod 102 are respectively inserted into the corresponding bearings, and one end of the spiral adjusting rod 102 extends outward. A drive motor with a reduction gearbox is installed at the extended end. The drive motor is connected to the extended end of the spiral adjusting rod 102. The drive motor drives the spiral adjusting rod 102 to rotate forward and backward, thereby adjusting the width between the sliders 103 fitted on the reverse thread, and thus adjusting the distance between the friction rotating wheels 105 on both sides.

[0027] like Figure 2 As shown, the clamp 2 has an outer circle and an inner square structure, including a circular outer shell. The circular shell is placed between two friction rotating wheels 105, which support the clamp 2. A square hole is provided in the center of the circular outer shell, and a square steel column is fitted into the square hole for clamping. The circular outer shell includes a bottom groove 201 and a fastening cover 202. A directional groove is provided in the middle of the bottom groove 201. The fastening cover 202 is installed on the bottom groove 201 to close the groove and form the square hole. After the bottom groove 201 and the fastening cover 202 are fastened together, the circular outer shell is formed, and the square hole formed after fastening is located in the center of the circular outer shell. The surface of the circular outer shell is provided with anti-slip texture.

[0028] This invention uses a snap-fit ​​method to form a circular clamp 2. First, the steel column is fitted into the groove of the bottom slot 201, and then the snap-fit ​​cover 202 is snapped onto the bottom slot 201. The two are then secured tightly with clips or other means. The two friction rotating wheels 105 are initially adjusted, and then the circular clamp 2 is placed between the two friction rotating wheels 105. Further fine-tuning of the two friction rotating wheels 105 is then performed according to the actual situation to ensure that the circular clamp 2 can be stably placed on them. Furthermore, when the friction rotating wheels 105 rotate and drive the circular clamp 2 to rotate, the circular clamp 2 remains stable. Since steel columns come in various sizes, the circular clamp 2 can be prepared in multiple sizes to accommodate different steel column dimensions.

[0029] Even if multiple types of circular clamps 2 are prepared, due to tolerance issues, the circular clamps 2 cannot perfectly fit all the steel columns. Once there is a gap between the steel column and the clamp 2, the steel column will inevitably wobble during the rotation process. The wobble will not only cause misalignment of the welded parts of the steel column, but in severe cases, it will also cause the device to overturn, resulting in a construction safety accident.

[0030] Therefore, as Figure 2 and 3As shown, a top plate 203 is installed on each of the four side walls of the square hole. A telescopic rod 204 is fixed to the rear side of the top plate 203. The telescopic rod 204 is provided with external threads. A turbine 205 with internal threads is fitted on the telescopic rod 204. The turbine 205 meshes with a worm gear 206. One end of the worm gear 206 extends outward and protrudes from the side of the clamp 2. By rotating the worm gear 206, the turbine 205 is driven, thereby causing the threaded turbine 205 and the telescopic rod 204 to move relative to each other.

[0031] The turbine 205 is fixedly installed in the circular housing by bearings, so that the turbine 205 can only rotate around its own central axis. The threaded telescopic rod 204 can then move laterally, so that the top plate 203 fixed at the end of the telescopic rod 204 moves laterally and abuts against the surface of the steel column, eliminating the gap caused by the tolerance of the steel column and firmly clamping the steel column in the center of the clamp 2.

[0032] Since the steel column needs to be clamped in the center of the clamp 2, adjusting each top plate 203 individually can easily cause deviation. Therefore, the present invention installs a drive sprocket 208 at the protruding end of the worm 206. The worm 205 and the worm 206 are installed in the housing of the clamp 2 corresponding to the side wall of the square hole. A chain 210 is connected between the four drive sprockets 208. The chain 210 makes the four worms 206 rotate synchronously, thereby making the four top plates 203 move synchronously.

[0033] The chain 210 is used to move the four top plates 203 synchronously, so that the clamped steel column is always located at the center of the clamp 2.

[0034] Meanwhile, to prevent the chain 210 from encroaching on the position of the central square hole of the clamp 2 and causing the chain 210 to come into contact with the steel column, the present invention also provides tension sprockets 209 on the circular outer shells corresponding to the four corners of the square hole, and the chain 210 passes around all the drive sprockets 208 and tension sprockets 209.

[0035] In order to ensure that the top plate 203 can move laterally and to prevent the top plate 203 from rotating together with the telescopic rod 204, a guide post 207 is also provided on the top plate 203. The circular outer shell is provided with a corresponding guide hole, and the guide post 207 is located next to the telescopic rod 204 and is parallel to the telescopic rod 204.

[0036] Example 2: In addition to square steel columns, there are also rectangular steel columns. For rectangular steel columns, since the clamp 2 provided by this invention is square and the four top plates 203 move synchronously and are also square and close together for clamping, two sides of the rectangular steel column cannot be clamped. When rotating, the unclamped side will fall off, thus affecting the quality and safety of welding.

[0037] Therefore, such as Figure 5As shown, the present invention installs an airbag 232 for clamping and eliminating gaps on a horizontally symmetrical top plate 203. Specifically, a storage basket 231 is provided on the horizontally corresponding top plate 203, and the airbag 232 is installed in the storage basket 231. An air inlet is provided on the side of the storage basket 231, and an air inlet pipe 233 is connected to the air inlet. A valve 234 is provided on the air inlet pipe 233, and the airbag 232 is inflated or contracted by inflating or deflating through the air inlet pipe 233.

[0038] Inflating the airbag 232 causes it to expand and clamp the central steel column, preventing it from falling due to intermittent shaking during the rotation process.

[0039] Example 3: Inflating the airbag 232 individually cannot guarantee that the airbag 232 is filled evenly, and inflating it individually is quite troublesome. After use, each airbag 232 needs to be deflated individually.

[0040] Therefore, the present invention further provides an inflation device, which includes a cylinder 501, a piston 502, and an inner plug 503, specifically as follows: Figure 6 As shown, a piston 502 is installed in the cylinder 501. An inner core tube is set in the center of the piston 502. An inner plug 503 is installed in the inner core tube of the piston 502. A compression spring is set between the inner plug 503 and the piston 502. Exhaust ports are set on both sides of the high-pressure chamber of the cylinder 501. The exhaust ports are connected to the air intake pipe 233 of the airbag 232.

[0041] By pushing the piston 502, the gas in the high-pressure chamber is pushed into the two connected air bladders 232, causing the air bladders 232 to expand synchronously. At the same time, due to the compression of the gas, the inner plug 503 in the inner core tube will compress the spring, leaving some high-pressure gas in the inner core tube.

[0042] The piston 502 continues to push to inflate the two air bladders 232 on both sides until the piston 502 blocks the two exhaust ports on the cylinder 501. The two air bladders 232 are inflated with equal amounts of air, and the connecting air pipes are closed at the same time, which can ensure that the two air bladders 232 expand to the same size at the same time.

[0043] During exhaust, piston 502 is pulled back. Since a small amount of high-pressure gas remains in the inner core tube during inflation, the expansion of the gas can force piston 502 to be pulled back, opening the exhaust port blocked by piston 502, and further extracting the gas from airbag 232, causing airbag 232 to contract and releasing the clamped steel column.

[0044] In this embodiment, the airbag 232 can be inflated in a coordinated manner, achieving the characteristics of simultaneous inflation and deflation in one step. At the same time, after inflation, the two airbags 232 are automatically isolated to avoid the beam and column pressing on the lower airbag 232, which would cause the lower airbag 232 to return air to the upper airbag 232.

[0045] The specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
