Description

Technical Field

[0001] The utility model relates to the technical field of steel box girder processing, and more specifically, to a steel box girder edge correcting machine. Background Art

[0002] Steel box girder is a cross beam with a box-like structure, usually made of steel. It has high load-bearing capacity and bending strength, and is often used as a beam material in bridges, building structures, roads, railways and other projects. Traditional correction methods mainly use manual flame correction and external force application. Due to the large manual operation error, the correction effect is not good, and the flatness of the corrected panel is difficult to meet the standard.

[0003] After searching, a Chinese patent with announcement number CN109909325A discloses a "steel box girder edge correction machine". When the steel box girder is set on the workbench, the gantry is set on the upper side of the steel box girder, and the upper surface of the fixed abutment plate on the gantry is abutted against the bottom surface of the steel box girder panel, and the correction plate slidably connected to the gantry is set on the upper side of the steel box girder panel. At this time, the second hydraulic cylinder works, driving the correction plate to move toward the steel box girder panel until the bottom surface of the correction plate is tightly abutted against the steel box girder panel, so that the steel box girder panel is flattened between the bottom surface of the correction plate and the upper surface of the fixed abutment plate. Therefore, the correction machine adopts a mechanical flattening method to correct the steel box girder panel, thereby improving the flatness of the steel box girder panel. Compared with artificial flame correction and the method of applying external force, the error is smaller, so that the corrected steel box girder is more in line with the use requirements.

[0004] When the above-mentioned straightening machine is in use, the second hydraulic cylinder drives the straightening plate to move toward the steel box girder panel, thereby flattening the steel box girder panel between the bottom surface of the straightening plate and the upper surface of the fixed abutment plate. It only simply applies extrusion pressure to the steel box girder, and the correction speed is slow. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a steel box girder edge straightening machine, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel box girder edge correction machine, comprising a connecting frame and a first extrusion plate, and the bottom end of the first extrusion plate is fixedly connected to the connecting frame, and the front and rear sides inside the connecting frame are fixedly connected with I-shaped plates, and a moving component is provided on the connecting frame, and the moving component includes a motor, a first bevel gear, a second bevel gear, forward and reverse screws, two sliders, a slide rod, two storage frames and two vertical plates.

[0007] The motor is fixedly installed on the inner rear side of the connecting frame, the rear side of the first bevel gear is fixedly connected to the end of the motor output shaft, the second bevel gear is fixedly sleeved on the forward and reverse screw rods, the forward and reverse screw rods are movably connected to one of the I-shaped plates through bearings, the sliding rod is fixedly connected to the other I-shaped plate, and the two ends of the forward and reverse screw rods and the sliding rod respectively pass through two sliders, and the bottom ends of the two storage frames are fixedly connected to the two sliders respectively.

[0008] Furthermore, threaded rods are movably provided on the two storage frames, and one end of the two threaded rods passes through the two vertical plates respectively, and two threaded sleeves are threadedly connected to the two threaded rods.

[0009] It can be seen that in the above technical solution, the threaded sleeve is rotated and moved away from the threaded rod, thereby releasing the fixation between the vertical plate and the storage frame, and replacing vertical plates of different heights, thereby facilitating the correction of different positions of the steel box girder.

[0010] Furthermore, two limiting plates are movably arranged inside the connection frame, and opposite sides of the two limiting plates are fixedly connected to the two sliding blocks respectively.

[0011] It can be seen that in the above technical solution, the reverse rotation of the motor drives the two sliders to move away from each other, thereby driving the two limit plates to move away from each other. The two limit plates can prevent the two sliders from moving out of the forward and reverse screw rods.

[0012] Furthermore, both of the two vertical plates are provided with an extrusion assembly, and both of the two extrusion assemblies include a second extrusion plate, a handle and two clamping blocks.

[0013] Furthermore, one side of the two handles is fixedly connected to the two second extrusion plates respectively, one side of the four clamping blocks is fixedly connected to the two second extrusion plates respectively, and the other sides of the four clamping blocks extend into the two vertical plates respectively.

[0014] Furthermore, an adjustment component is provided at the bottom of the connection frame, and the adjustment component includes a base, four telescopic rods and a hydraulic cylinder.

[0015] Furthermore, the top ends of the hydraulic cylinder and the four telescopic rods are fixedly connected to the connection frame, and the bottom ends of the hydraulic cylinder and the four telescopic rods are fixedly connected to the base.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The utility model drives two vertical plates to move toward each other through the operation of a motor. The two vertical plates perform preliminary extrusion on the steel box beam, and then heats the steel box beam with a flamethrower to make the steel reach a certain temperature, soften the steel, and improve its plasticity. Finally, the handle is moved horizontally to move the second extrusion plate into the vertical plate. The two vertical plates drive the two second extrusion plates to move toward each other to correct the edge position of the steel box beam. The operation is simple and the correction speed is greatly improved.

[0018] 2. The utility model drives the connection frame to move upward by extending the piston rod on the hydraulic cylinder, thereby driving the first extrusion plate to move upward, and the bottom of the steel box girder is squeezed by the first extrusion plate. At the same time, the four telescopic rods move vertically with the hydraulic cylinder, which can improve the stability of the connection frame, has a simple structure, and is easy to use.

[0029] The motor 301 is fixedly installed on the inner rear side of the connecting frame 1, the rear side of the first bevel gear 302 is fixedly connected to the end of the output shaft of the motor 301, the second bevel gear 303 is fixedly sleeved on the forward and reverse screw rods 304, the forward and reverse screw rods 304 are movably connected to one of the I-shaped plates 7 through bearings, the sliding rod 306 is fixedly connected to the other I-shaped plate 7, and the two ends of the forward and reverse screw rods 304 and the sliding rod 306 respectively pass through the two sliders 305, and the bottom ends of the two storage frames 307 are fixedly connected to the two sliders 305 respectively.

[0030] Furthermore, threaded rods 309 are movably provided on the two storage frames 307, and one end of the two threaded rods 309 passes through the two vertical plates 308 respectively. Two threaded sleeves 310 are threadedly connected to the two threaded rods 309. The threaded sleeves 310 are rotated and moved away from the threaded rods 309 to release the fixation between the vertical plates 308 and the storage frames 307, and the vertical plates 308 of different heights are replaced, thereby facilitating the correction of different positions of the steel box girder.

[0031] Furthermore, two limit plates 311 are movably provided inside the connecting frame 1, and the opposite sides of the two limit plates 311 are fixedly connected to the two sliders 305 respectively. The motor 301 reverses to drive the two sliders 305 to move away from each other, thereby driving the two limit plates 311 to move away from each other. The two limit plates 311 can prevent the two sliders 305 from moving out of the forward and reverse screw rods 304.

[0032] Furthermore, an extrusion assembly 4 is provided on each of the two vertical plates 308, and each of the two extrusion assemblies 4 includes a second extrusion plate 401, a handle 402 and two clamping blocks 403, one side of the two handles 402 is fixedly connected to the two second extrusion plates 401, one side of the four clamping blocks 403 is fixedly connected to the two second extrusion plates 401, and the other sides of the four clamping blocks 403 extend into the two vertical plates 308, respectively.

[0036] When in use, the steel box beam is located at the top of the connecting frame 1 and between the two vertical plates 308. The staff starts the motor 301, and the motor 301 drives the first bevel gear 302 to rotate. Since the first bevel gear 302 is in contact with the second bevel gear 303, the first bevel gear 302 can drive the second bevel gear 303 to rotate, thereby driving the forward and reverse screw rods 304 to rotate. Since the two sliders 305 are both threadedly connected to the forward and reverse screw rods 304, the slide rod 306 limits the rotation of the two sliders 305, so the forward and reverse screw rods 304 can drive the two sliders 305 to move toward each other, thereby driving the two vertical plates 3 08 move toward each other, the two vertical plates 308 perform preliminary extrusion on the steel box beam, and then use a flamethrower to heat the steel box beam to make the steel reach a certain temperature, soften the steel and improve its plasticity. Finally, move the handle 402 horizontally and move the second extrusion plate 401 into the vertical plate 308. The two vertical plates 308 drive the two second extrusion plates 401 to move toward each other to correct the edge position of the steel box beam. The operation is simple and the correction speed is greatly improved. At the same time, the second extrusion plate 401 drives the two blocks 403 to move in the vertical plate 308 to prevent the second extrusion plate 401 from deflecting when moving.
