一种轧辊限位装置

Abstract

本实用新型属于轧制机械技术领域，公开了一种轧辊限位装置，包括压板组件，压板组件包括压板、锁紧件和承托件，承托件固定连接于牌坊，用于承载压板，压板上开设有沿压板长度方向延伸的腰型孔，锁紧件穿设于腰型孔，且锁紧件一端连接于牌坊，另一端用于将压板锁紧于牌坊上，其中，压板具有与轴承座端面抵接的限位位置和释放轴承座的拆卸位置，当压板位于拆卸位置时，压板沿轴承座轴向的投影落在轴承座端面之外，以使轴承座可轴向移动。松动锁紧件即可移动压板，无需拆下压板，简化了换辊步骤，能够显著缩短换辊时间，提高轧辊检修效率；承托件对压板起到支撑和导向作用，无需托举压板，能够轻松实现单人操作，有利于保障工作人员的人身安全。

Claims

1. A roll stop device, characterized by, The system includes a pressure plate assembly, which comprises a pressure plate (1), a locking member (2), and a support member (3). The support member (3) is fixedly connected to the archway (100) and is used to support the pressure plate (1). The pressure plate (1) has a waist-shaped hole (11) extending along the length direction of the pressure plate (1). The locking member (2) passes through the waist-shaped hole (11), and one end of the locking member (2) is connected to the archway (100), while the other end is used to lock the pressure plate (1) onto the archway (100). The pressure plate (1) has a limiting position that abuts against the end face of the bearing seat (200) and a disassembly position that releases the bearing seat (200). When the pressure plate (1) is in the disassembly position, the projection of the pressure plate (1) along the axial direction of the bearing seat (200) falls outside the end face of the bearing seat (200), so that the bearing seat (200) can move axially.

2. The roll positioning device according to claim 1, characterized in that The support member (3) includes a vertical part (31) and a horizontal part (32) connected at an angle. The vertical part (31) is fixedly connected to the archway (100), and the horizontal part (32) is used to support the pressure plate (1).

3. The roll positioning device of claim 2, wherein The vertical part (31) is welded to the archway (100).

4. The roll positioning device of claim 2, wherein A stop bar (33) is provided at one end of the horizontal part (32) away from the vertical part (31). The stop bar (33) is used to abut against the pressure plate (1) to limit the displacement of the pressure plate (1) along the axial direction of the bearing seat (200).

5. The roll positioning device of claim 1, wherein The length of the support member (3) is not less than the length of the waist-shaped hole (11).

6. The roll positioning device of claim 1, wherein The pressure plate (1) includes an abutting part (12) and a snap-fit ​​part (13) connected at an angle. The abutting part (12) is used to abut against the end face of the bearing seat (200). The snap-fit ​​part (13) is connected to the end of the abutting part (12) away from the bearing seat (200) and is used to snap with the support member (3).

7. The roll positioning device of claim 1, wherein A handle is connected to the end of the pressure plate (1) away from the bearing seat (200).

8. The roll positioning device of claim 1, wherein The locking component (2) includes a stud (21) and a nut (22). One end of the stud (21) is connected to the archway (100), and the other end passes through the waist-shaped hole (11) and is threadedly connected to the nut (22).

9. The roll positioning device of claim 8, wherein A washer (4) is provided between the nut (22) and the pressure plate (1).

10. The roll stop device according to any one of claims 1 to 9, characterized in that The roll limiting device includes at least two pressure plate assemblies, and the pressure plate assemblies are provided on both sides of the bearing housing (200).
