TECHNICAL FIELD

[0001] The present application relates to the field of equipment for hot rolling seamless steel pipe production, in particular to a guide plate auxiliary turnover device. BACKGROUND

[0002] In the production of hot rolling straight rolling 900mm and above seamless steel pipes, the guide plate generally refers to a tool or device used to guide and position the billet or pipe billet during the rolling process in the rolling mill. The guide plate, through its specific shape and position, helps the billet or pipe billet to maintain the correct position and direction in the rolling mill, to ensure the accuracy and stability during the rolling process.

[0003] In hot rolling production, the guide plate needs to be replaced according to the specification. Generally, the upper guide plate is placed downward and the lower guide plate is placed upward, which can be directly lifted away, but sometimes part of the guide plate cannot be used, so the guide plate needs to be turned over for use. There is a safety hazard in using a lifting belt to cooperate with a crane to turn over. At the same time, before the guide plate is replaced, it needs to be inspected for contact with the steel pipe. The contact surface of the upper guide plate is downward, and there is a safety hazard if the crane is lifted for inspection. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the possibility of safety hazards, the present application provides a guide plate auxiliary turnover device.

[0007] By adopting the above technical solution, when the guide plate needs to be turned over, the guide plate is only moved into the turnover space by using a lifting belt to cooperate with a crane, then the lifting belt is released, and finally the driving member is started to drive the rotation of the turnover frame, so that the guide plate is turned over upward and downward, thereby improving the stability of the guide plate during turnover, improving the safety of the guide plate during turnover, and reducing the possibility of safety hazards.

[0008] Preferably, the driving member comprises a speed reducer and a driving motor, the speed reducer is connected with the operation table, the output shaft of the driving motor is connected with the input shaft of the speed reducer, and the output shaft of the speed reducer is fixed circumferentially with the turnover frame.

[0009] By adopting the technical scheme, the driving motor reduces the rotating speed through the speed reducer, improves the torque, and makes the rotation of the turnover frame more stable and controllable. This configuration can realize accurate turnover operation and reduce errors. The speed reducer can reduce the burden of the driving motor, avoid vibration and instability caused by high-speed operation, and thus improve the stability and durability of the turnover frame.

[0010] Preferably, a sliding groove is formed on the turnover plate, a sliding block is slidably arranged in the sliding groove, the sliding direction of the sliding block is the length direction of the turnover plate, a buffer spring is arranged in the sliding groove, one end of the buffer spring is connected with the sliding block, and the other end of the buffer spring is connected with the inner wall of the sliding groove. The guide plate is in contact with the sliding block when the turnover frame rotates.

A locking member for locking the position of the blocking plate is arranged in the turnover plate.

[0013] By adopting the technical scheme, after the guide plate is moved into the turnover space by the workers with the lifting belt and the travelling crane, the locking member is opened, the blocking block is ejected from the moving groove, and thus the guide plate is prevented from separating from the turnover space when the turnover frame is turned over.

[0014] Preferably, the locking member comprises a blocking block and a locking spring, a locking groove is formed on the turnover plate and communicates with the moving groove, the blocking block is slidably connected with the locking groove and the sliding direction is the length direction of the blocking plate, one end of the locking spring is connected with the inner wall of the locking groove, and the other end of the locking spring is connected with the blocking block. The opening of the moving groove is closed when the blocking block slides.

The design of the groove provides a convenient operation area for the staff, making them easier to grab and operate the blocking block. This is especially important for devices that need to be adjusted or operated frequently, which can improve operational efficiency.

[0018] Preferably, two buffer blocks are arranged on the operation table, and when the turnover frame rotates, the two sides of the turnover plates close to the operation table respectively abut against the two buffer blocks, and the turnover plates are in a horizontal state when abutting against the buffer blocks.

[0019] By adopting the above technical scheme, the buffer block provides a stable support point to ensure that the turnover plate can remain horizontal during rotation or operation. This stability reduces the risk of tilting or imbalance of the turnover plate, helping to improve the accuracy and safety of operation; when the turnover plate contacts the buffer block, the buffer block can absorb part of the impact force, reducing the mechanical wear and damage of the turnover plate. This design helps to prolong the service life of the turnover plate and reduce the frequency of maintenance and replacement.

[0020] Preferably, two locking rods are further included, and the two turnover plates are hinged, one of the turnover plates is provided with a rotating groove and a first locking hole is arranged on both sides of the width direction of the rotating groove, a rotating shaft is arranged in the rotating groove, the other turnover plate is provided with a plurality of second locking holes on both sides of the width direction and is sleeved on the rotating shaft, and the locking rods are sequentially inserted and matched with the first locking hole and the second locking hole.

[0022] Preferably, the width of the turnover plate is less than the length of the guide plate.

[0023] By adopting the above technical scheme, since the width of the turnover plate is less than the length of the guide plate, the two ends of the guide plate in the length direction can exceed the turnover frame, which facilitates moving the guide plate into the turnover space with the lifting belt cooperating with the trolley, so that the lifting belt does not interfere with the turnover of the turnover frame.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] 1. When the guide plate needs to be turned over, the guide plate is only moved into the turnover space with the lifting belt cooperating with the trolley, then the lifting belt is released, and finally the driving member is started to drive the turnover frame to rotate, so that the guide plate is turned over up and down, thereby improving the stability of the guide plate during turnover, improving the safety of the guide plate during turnover, and reducing the possibility of safety hazards;

[0026] 2. The drive motor reduces the speed through the reduction gear, improves the torque, and makes the rotation of the turnover frame more stable and controllable. This configuration can realize precise turnover operation and reduce errors; the reduction gear can reduce the burden of the drive motor, avoid vibration and instability caused by high-speed operation, and thus improve the stability and durability of the turnover frame;

[0027] 3. The buffer spring can effectively absorb the impact and vibration generated during the turnover process, protect the guide plate, and reduce mechanical wear and possible damage; the sliding block in the sliding groove slides along the length direction of the turnover plate, which helps to smoothly guide the turnover process of the guide plate and ensures the smoothness and consistency of the turnover action; the contact between the sliding block and the guide plate can ensure that the guide plate maintains a stable position during the turnover process, reduces the turnover error caused by uneven movement of the guide plate, and improves the turnover precision.
