[0021] Embodiment 1 of the present utility model is as follows:

[0022] A roller lifting mechanism comprises a bracket 1, wherein the bracket 1 comprises a plurality of legs and connecting rods to form a rectangular frame structure, a conveying part 4 is arranged on the upper part of the bracket 1, and the conveying part 4 comprises a frame and a plurality of conveying rollers evenly arranged inside the frame, and the upper surface of the conveying rollers is slightly higher than the upper surface of the frame, thereby realizing the conveying function, a driving device is arranged on the upper part of the bracket 1, comprising a motor, a reducer and a transmission chain, and the conveying rollers are driven to rotate by the motor, and gaps are arranged between the conveying rollers, and a plurality of roller mechanisms and a plurality of conveying rollers are arranged in sequence at intervals to ensure that the steel plate can be lifted up and separated from the conveying rollers.

[0023] The roller mechanism includes a rectangular tube 5, a support plate 6 is arranged on the upper part of the rectangular tube 5, and the roller mechanism also includes a plurality of evenly arranged through holes, which pass through the upper surface of the support plate 6 and the rectangular tube 5 in sequence; a limit rod 11 is arranged on the upper part of the support plate 6, and the limit rod 11 is movably located inside the through hole, and the upper end of the limit rod 11 is fixedly connected with a top plate 9, and a spring 10 is arranged between the top plate 9 and the support plate 6, the upper end of the spring 10 is connected to the top plate 9, and the lower end of the spring 10 is connected to the support plate 6, and a roller seat is arranged on the upper part of the top plate 9, and a rotating wheel 8 is rotatably arranged on the roller seat, and the rotating wheel 8 is connected to the roller seat through a deep groove ball bearing.

[0024] When the steel plate is pressed on the rotating wheel 8, the spring 10 will be stressed and compressed, thereby shortening the distance between the top plate 9 and the support plate 6. At this time, the limit rod 11 will pass through the through hole and move to the inside of the rectangular tube 5. Therefore, when the roller device contacts the steel plate, the rotating wheel 8 at different positions can adapt to the curvature of the steel plate, and the contact support between the rotating wheel 8 and the steel plate is guaranteed by compressing the spring 10, which not only ensures that the rotating wheel 8 will not deviate when moving vertically up and down, but also ensures that the limit rod 11 will not affect the moving range of the rotating wheel 8, ensuring that the rotating wheel 8 can be close to the steel plate and improve the supporting capacity.

[0025] A lifting mechanism is also provided at the lower part of the bracket 1, and the lifting mechanism includes a bearing seat 2 fixedly mounted on the support leg, and a hydraulic cylinder 3 is fixedly provided on the upper part of the bearing seat 2. The upper end of the piston rod of the hydraulic cylinder 3 is connected to the rectangular tube 5, and the rectangular tube 5 is driven up and down by the hydraulic cylinder 3. When not in use, the roller mechanism is located below the conveying roller and will not affect the forward movement of the steel plate. When the steel plate is offset, the roller mechanism is lifted up by the lifting mechanism to make the steel plate contact with the rotating wheel 8, thereby converting the static friction between the steel plate and the conveying roller into the rolling friction between the steel plate and the rotating wheel 8, and the friction force is reduced to a level that can be adjusted by manpower, so that it is convenient to manually correct the position of the steel plate.

[0026] It also includes two side plates 7 fixedly arranged on the upper part of the rectangular tube 5. The two side plates 7 are respectively located on both sides of the spring 10, which can play a protective role to prevent the roller mechanism from deflecting and protect the spring 10 from being damaged.

[0027] Each roller mechanism includes two hydraulic cylinders 3, which are respectively located at two ends of the rectangular tube 5 and work synchronously to ensure that the roller mechanism remains in a horizontal state.

[0028] The width of the supporting plate 6 is greater than the diameter of the spring 10 , and the diameter of the top plate 9 is greater than the diameter of the spring 10 , thereby ensuring that the spring 10 will not fall off.

[0029] In actual work, the motor drives the conveyor roller to rotate synchronously through the reducer and the transmission chain to move the steel plate forward. When the position of the steel plate is offset, the hydraulic cylinder 3 lifts the steel plate through the roller mechanism to make it out of contact with the conveyor roller. At this time, the worker can manually push the steel plate to move to adjust its position.

[0030] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.
