Description

Technical Field

[0001] This utility model relates to the field of steel structure processing, and in particular to a plate rolling device for processing steel structures for offshore platforms. Background Technology

[0002] Offshore platforms are structures that provide production and living facilities for activities such as drilling, oil production, collection and transportation, observation, navigation and construction at sea. A large amount of steel structures are used in the construction of offshore platforms, and a considerable portion of the steel needs to be processed using plate rolling machines.

[0003] A plate rolling machine is a processing equipment that rolls metal sheets into the required circular, arc, or conical shapes. The plate rolling machine works on the principle that three points form a circle. The predetermined shape is obtained by adjusting the relative position between the side rollers and the top roller of the plate rolling machine.

[0004] For example, patent document CN222710530U discloses a plate rolling device for ship steel structure processing, belonging to the technical field of shipbuilding related equipment. It includes a three-axis plate rolling machine body, with a feeding auxiliary frame fixedly installed on the front surface of the body. Multiple auxiliary rollers are rotatably installed inside the feeding auxiliary frame, and two positioning plates with adjustable positioning spacing are installed within the feeding auxiliary frame. A support frame is fixedly installed on the rear surface of the three-axis plate rolling machine body, with an arc-shaped frame rotatably installed inside the support frame. Multiple fixing rods are fixedly installed inside the arc-shaped frame, and rollers are rotatably installed on the outer surface of each fixing rod. Arc-shaped plates with adjustable positioning spacing are installed between the multiple fixing rods. A drive mechanism is installed between the support frame and the arc-shaped frame, used to drive the arc-shaped frame to rotate and change its position. This invention effectively replaces manual assistance in existing production processes, reduces labor costs, improves the automation and intelligence of production, and reduces operator contact with hazardous areas, thus reducing operational risks.

[0005] In the existing technology, the arc or circular steel structures used for offshore platforms are generally large in volume. When producing rolled plates, the upper end needs to be supported to ensure the processing effect and safety. However, the steel plate is prone to vibration during the rolling process. This vibration may not only cause the arc or circular steel structure to become out of round and fail to meet the processing requirements, but also bring safety hazards. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8As shown, a plate rolling device for processing steel structures of offshore platforms includes a plate rolling machine body. A top support mechanism is provided on the rear side of the plate rolling machine body, and two side support mechanisms are symmetrically arranged on both sides of the plate rolling machine body. The side support mechanisms include side brackets 301, and a tilting wing plate 303 is rotatably connected to the top bearing of the side bracket 301. Two third hydraulic rods 302 are hinged to the side brackets 301 and are symmetrically arranged front and rear. The other end of the third hydraulic rods 302 is hinged to the other end of the tilting wing plate 303. A sliding crossbar 306 is slidably connected to the tilting wing plate 303. The plate 303 is equipped with a moving component for driving the sliding crossbar 306 to slide. A pivot 307 is hinged to the sliding crossbar 306. Two symmetrically arranged U-shaped frames 308 are welded and fixed to both ends of the pivot 307. Two symmetrically arranged roller support sliders 310 are slidably connected to the top of the U-shaped frames 308. A support roller 311 is rotatably connected between the front and rear roller support sliders 310 via a bearing. Two symmetrically arranged spring damping rods 309 are bolted to the U-shaped frames 308. The spring damping rods 309 are prior art, and their structure will not be described here. The output end of the spring damping rod 309 is bolted to the roller support slider 310. During the process of the steel plate entering the device, the flipping wing plate 303 remains horizontal. At this time, the two support rollers 311 on one side can assist the steel plate in entering the device. After the steel plate enters between the fixed roller 103 and the movable roller 106 and begins to be rolled, as the curvature of the steel plate continues to increase, the third hydraulic rod 302 drives the motor 304 to flip upward. During the flipping process, the moving component drives the sliding crossbar 306 to move, and the sliding crossbar 306 drives the rotating shaft 30 7. The movement ensures that the two support rollers 311 remain close to the steel plate. Furthermore, due to the rotational connection between the rotating shaft 307 and the sliding crossbeam 306, automatic adjustment can be achieved when the two support rollers 311 are close to the steel plate, ensuring that both support rollers 311 can support the steel plate. If vibration occurs during processing, the steel plate will transmit the vibration to the support rollers 311, which will then transmit it to the roller support slider 310, and finally to the spring damping rod 309, thereby absorbing the vibration and reducing its impact on the rolling process.

[0031] The plate rolling machine mainly includes a machine body 101. The internal structure of the machine body 101 is existing technology and will not be described in detail here. A control power box 102 is fixedly connected to the rear of the machine body 101. Its internal structure and the commercially available CNC system it houses are also existing technology and will not be described in detail here. Several movable rollers 106 are mounted on the control power box 102; three are selected here. The other end of each movable roller 106 is mounted on the front end of the machine body 101. A fixed roller 103 is mounted on the top of the control power box 102. A tilting plate 104 is hinged to the front end of the machine body 101. The tilting plate 104 is connected to the fixed roller 103. One end is movably connected, and a first hydraulic rod 105 is hinged to the front side of the tilting plate 104. The other end of the first hydraulic rod 105 is rotatably connected to the machine body 101. The machine body 101 is bolted to two side supports 301. Through the cooperation of the machine body 101 and the control power box 102, the distance between the fixed roller 103 and the three movable rollers 106 is changed to achieve the rolling of the steel plate. After the rolling is completed, the first hydraulic rod 105 drives the tilting plate 104 to tilt. After the tilting plate 104 tilts, the workers can use a crane or other devices to unload the rolled steel structure from the device.

[0032] The top support mechanism includes a rear support 201 bolted to the rear side of the machine body 101. A lifting slider 203 is slidably connected to the upper end of the rear support 201. A support crossbar 204 is bolted to the front end of the lifting slider 203. Several ball bearings 205 are rotatably connected to the support crossbar 204. A second hydraulic rod 202 is fixedly connected to the lower end of the rear support 201. The output end of the second hydraulic rod 202 is fixedly connected to the lifting slider 203. The support crossbar 204 has a semi-dodecagonal cross section. The bottom of the crossbar 204 is equipped with reinforcing ribs. During the rolling process, when the steel plate is rolled into a shape that exceeds a semicircle, the second hydraulic rod 202 drives the lifting slider 203 to slide on the upper end of the rear support 201. The lifting slider 203 drives the support crossbar 204 to rise and fall. The support crossbar 204 drives several balls 205 to approach the steel plate and support it. The arrangement of the balls 205 ensures that the steel plate can be provided with sufficient support during the rolling process and the unloading process, and will not affect the movement of the steel plate.

[0033] The moving component includes a lead screw 305 rotatably connected to the middle of the tilting wing plate 303. A motor 304 is bolted to the outer end of the tilting wing plate 303. The output end of the motor 304 is fixedly connected to the lead screw 305. The lead screw 305 is threadedly connected to the sliding crossbar 306. The motor 304 drives the lead screw 305 to rotate. The lead screw 305 drives the sliding crossbar 306 to move axially along the lead screw 305 through the threaded connection.

[0034] The sliding crossbeam 306 has protrusions on both sides, and the rotating shaft 307 has two symmetrically arranged limiting strips 312 on both sides. The two ends of the limiting strips 312 are fixedly connected to the two U-shaped frames 308 respectively. The limiting strips 312 can contact the sliding crossbeam 306 through the hinge between the rotating shaft 307 and the sliding crossbeam 306. The support roller 311 can adaptively approach the steel plate, but a limiting structure is required to prevent excessive rotation between the rotating shaft 307 and the sliding crossbeam 306. Therefore, two symmetrically arranged limiting strips 312 are provided. When the rotating shaft 307 drives the U-shaped frame 308 to rotate to the limit, the limiting strips 312 contact the protrusions on the sliding crossbeam 306, thereby stopping the rotation of the rotating shaft 307.

[0035] Working principle: During the steel plate entry process, the flipping wing plate 303 remains horizontal. At this time, the two support rollers 311 on one side can assist the steel plate in entering the device. After the steel plate enters between the fixed roller 103 and the movable roller 106, the distance between the fixed roller 103 and the three movable rollers 106 is changed through the cooperation of the machine body 101 and the control power box 102 to achieve the rolling of the steel plate. During the rolling process, when the steel plate is rolled into a shape that exceeds a semi-circle, the second hydraulic rod 202 drives the lifting slider 203 to slide on the upper end of the rear support 201. The lifting slider 203 drives the support crossbar 204 to rise and fall. The support crossbar 204 drives several balls 205 to approach the steel plate and support it. During the rolling process, as the curvature of the steel plate continues to increase, the third hydraulic rod 302 drives the motor 304 to flip upward. During the process, the moving component drives the sliding crossbeam 306 to move, and the sliding crossbeam 306 drives the rotating shaft 307 to move, so that the two support rollers 311 are always close to the steel plate. In addition, due to the rotational connection between the rotating shaft 307 and the sliding crossbeam 306, automatic adjustment can be achieved when the two support rollers 311 are close to the steel plate, ensuring that both support rollers 311 can support the steel plate. If vibration occurs during processing, the steel plate transmits the vibration to the support rollers 311, the support rollers 311 transmit it to the roller support slider 310, and the roller support slider 310 transmits it to the spring damping rod 309, thereby absorbing the vibration and reducing the impact of vibration on the rolling process. After the rolling is completed, the first hydraulic rod 105 drives the tilting plate 104 to tilt. After the tilting plate 104 tilts, the workers can use a crane or other devices to unload the rolled steel structure from the device.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
