Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, and particularly relates to a turnover device for steel structure welding. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. During the processing of steel structures, it is often necessary to weld components on steel materials, and it is often necessary to turn over the components during the welding process, so turnover equipment is needed.

[0003] In the Chinese utility model patent with the publication number of CN 210549238 U, a turnover device for steel structure welding is disclosed, which includes a bottom plate. One side of the upper surface of the bottom plate is fixedly installed with a first support plate. One end of the output shaft of the motor penetrates through the second support plate and is fixedly installed with a rotating shaft. One end of the rotating shaft is fixedly installed with a second fixing plate. The upper part of the first support plate is fixedly installed through a threaded sleeve. A threaded rod is in threaded connection with the threaded sleeve. One side of the rotating mechanism is fixedly installed with a first fixing plate. Both ends of one side of the first fixing plate are fixedly installed with guide rods. The other end of the threaded rod extends to the other side of the threaded sleeve and is fixedly installed with a rotating disc. One side of the rotating disc is fixedly installed with a rotating handle. One side of the upper surface of the threaded sleeve is fixedly installed with a fastening nut. For the above related technologies, the inventor believes that there are the following defects: the second fixing plate is driven by the motor to rotate at a constant speed to turn over the steel material to be welded. However, when manual welding is performed on the welding part, there is a time difference in the welding time for each welding point part. If the steel material to be welded is turned over at a constant speed, it will cause uneven welding and affect the welding quality. Therefore, it is necessary for the welding operator to manually turn over the steel material to be welded according to his own welding rhythm. Content of the Utility Model

[0024] Please refer to Figures 1-3 , the present utility model provides a technical solution: a flipping device for steel structure welding, including a bottom plate 1, a first fixing plate 2 is fixedly provided on one side of the upper end of the bottom plate 1, a first flipping disc 3 is rotatably installed on one side of the first fixing plate 2, and the first flipping disc 3 is driven to rotate by a first handwheel 5;

[0025] A sliding plate 9 is slidably provided on the upper end of the bottom plate 1, the sliding plate 9 is driven to translate by a translation mechanism, and a second flipping disc 10 is rotatably installed on one side of the sliding plate 9;

[0026] A second rotating shaft 11 is provided on one side of the second flipping disc 10, and the second rotating shaft 11 is rotatably installed on the sliding plate 9;

[0027] When the sliding plate 9 translates, it drives the second flipping disc 10 to approach the first flipping disc 3 for clamping the material steel to be welded.

[0028] Among them, the sliding plate 9 is driven to translate by a translation mechanism, so that the second flipping disc 10 rotatably installed on the sliding plate 9 approaches the first flipping disc 3 rotatably installed on the first fixing plate 2, so that the first flipping disc 3 and the second flipping disc 10 clamp the material steel to be welded, and then the first handwheel 5 is rotated manually to make the first flipping disc 3 rotate, so that the material steel clamped between the first flipping disc 3 and the second flipping disc 10 is flipped, and the first handwheel 5 can be rotated according to the welding speed and rhythm of the welder himself, which is convenient for the welder to operate.

[0029] The first flipping disk 3 is rotatably mounted on the first fixed plate 2 through the first rotating shaft 4, and an anti-reverse mechanism is fixedly provided on the first rotating shaft 4;

[0030] The anti-reverse mechanism includes a ratchet wheel 6, a pawl 7 and a spring 8. The ratchet wheel 6 is fixedly mounted on the first rotating shaft 4 and is located outside the first fixed plate 2. One end of the pawl 7 is meshed with the ratchet wheel 6, and the other end is rotatably connected to the first fixed plate 2 through a fixing pin. One end of the spring 8 is connected to the pawl 7 through a fixing column, and the other end is connected to the first fixed plate 2 through a fixing pin.

[0031] Among them, the anti-reverse mechanism is used to prevent the first flipping disk 3 from reversing, thereby affecting the stability during the welding process and the welding rhythm of the welding operator. When rotating the first handwheel 5, the ratchet wheel 6 is rotated through the first rotating shaft 4. When the pawl 7 is meshed with the ratchet wheel 6, the first rotating shaft 4 cannot reverse. Therefore, by intermittently rotating the first handwheel 5, the pawl 7 and the ratchet wheel 6 can always be kept in the meshed state, that is, the flipping function is realized and the reverse can be prevented.

[0038] The working principle and usage process of the present utility model:

[0039] By rotating the second handwheel 14, the threaded rod 12 rotates, causing the threaded rod 12 to push the sliding plate 9 to slide on the two sets of guide rails 16, and making the sliding plate 9 approach the first fixing plate 2, so that the second flipping disc 10 approaches the first flipping disc 3 and clamps the material steel to be welded; then, by manually rotating the first handwheel 5, the first flipping disc 3 rotates, causing the material steel clamped between the first flipping disc 3 and the second flipping disc 10 to flip. The first handwheel 5 can be rotated according to the welding speed and rhythm of the welder himself, which is convenient for the welder to operate; among them, the anti-reverse mechanism is used to prevent the first flipping disc 3 from reversing, thereby affecting the stability during the welding process and the welding rhythm of the welder. When rotating the first handwheel 5, the ratchet 6 rotates through the first rotating shaft 4. When the pawl 7 meshes with the ratchet 6, the first rotating shaft 4 cannot reverse. Therefore, by intermittently rotating the first handwheel 5, the pawl 7 and the ratchet 6 can always be kept in the meshing state, that is, the flipping function is realized and the reverse can be prevented.
