[0002] The front part of the guide cylinder inside the original closed support of the leveling mill of the 1700 hot rolling production line was fixed with screws. Due to long-term operation and vibration, the screws often broke, and the cylinder body was damaged and leaked oil. The tail end of the cylinder was close to the roller, and the flange screws were stripped and scratched the roller, causing surface scratches and pits. During the internal telescopic movement, the hose was severely worn and often leaked oil. The pin shaft fixing structure at the bottom of the rotating cylinder often fell out after long-term operation. The cylinder body had a large swing angle, and the seal of the tail flange block leaked oil. Frequent equipment failures were not conducive to stable production. The above problems were solved by studying the modification of the support plate and cylinder body installation structure and the pipeline modification. Summary of the Invention

The bottom of the support plate body 8 is fixed with two vertical plates 9 by bolts. The two vertical plates 9 are arranged front and back, so that the original closed support plate body 8 is transformed into the current open support plate body 8. The components on the support plate body 8 are easy to maintain. The front side of the mounting plate 4 is fixed with a fixing plate 5 by bolts, and the front side of the fixing plate 5 is installed with a guide cylinder 6 by shaft rotation. The fixing plate 5 is rotated to install the tail end position of the guide cylinder 6 to limit the tail end position of the guide cylinder 6. The side where the two vertical plates 9 are close to each other is fixed with the same limiting axis and the same connecting axis 11 by welding. , the connecting shaft 11 is located on the right side of the limit shaft, the guide cylinder 6 and the limit shaft are movably connected, the guide cylinder 6 and the limit shaft are connected by screws, and the front side of the base 1 is rotatably installed with a steering cylinder 10 through a rotating shaft. The specifications of the steering cylinder 10 and the guide cylinder 6 can be selected according to actual conditions. The working process is a prior art and will not be described here. The top of the steering cylinder 10 extends to the side where the two vertical plates 9 are close to each other and is movably connected to the connecting shaft 11. The movable connection is similar to the movable connection of a crane boom. The side of the tail end plate 7 close to the roller 3 is arranged in an arc shape, and the arc end of the tail end plate 7 is coaxial with the roller 3. The tail end plate 7 and the roller 3 are not in contact. The steering cylinder 10 and the guide cylinder 6 are staggered and do not interfere with each other. The fixed plate 5 is located below the roller 3. The front side of the support seat 2 is fixedly installed with an L-shaped plate 12 by welding, and the bottom of the L-shaped plate 12 is fixedly installed with an upper positioning block 13.

[0030] Example 2
[0031] The difference between this embodiment and embodiment 1 is that the L-shaped plate 12, the upper positioning block 13, the buffer seat 14 and the buffer spring 16 may not be provided on the support seat 2. Then, there is no limiter when the guide cylinder 6 is running, and the support plate body 8 and the tail end plate 7 will scratch the roller 3 when moving. Since the buffer spring 16 is not provided, the speed of the steering cylinder 10 is too fast during operation, and the vibration generated is relatively large.
[0032] In the present invention, during use, the steering cylinder 10 can drive the mounting plate 4, the tail end plate 7 and the support plate body 8 to rotate around the rotation point on the support seat 2, and the guide cylinder 6 guides the operating position of the support plate body 8. The upper positioning block 13 and the lower positioning block perform bidirectional positioning on the position of the guide cylinder 6. The guide cylinder 6 will not vibrate frequently during operation, thereby extending the service life of the screws on the guide cylinder 6. The guide cylinder 6 is staggered at the tail end of the fixed plate 5 and the roller 3. Therefore, during the operation of the guide cylinder 6, the roller 3 will not be scratched. During the operation of the steering cylinder 10, the buffer spring 16 is provided for buffering, so that the operation process of the steering cylinder 10 is smoother, the vibration generated is smaller, and the operating angle of the steering cylinder 10 is reduced, so the wear of the steering cylinder 10 is reduced, thereby extending the service life of the steering cylinder 10.
[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
