Description

Technical Field

[0001] The utility model relates to a pin shaft anti-dropping device, in particular to a pin shaft anti-dropping device for connecting a rolling mill transverse floor Background Art

[0002] The rolling mill transverse floor is an important equipment for changing working rolls. Before changing the working rolls, the entrance side floor and the exit side floor need to be transversely moved. The entrance side floor and the exit side floor are connected by a pin shaft. The pin shaft is installed under the floor cover and is not easy to check. Due to the gap at the floor connection, the connecting pin shaft frequently falls off when the floor moves transversely. Once the fall-off is not discovered, it may cause damage to the floor transverse movement device, which will affect the production of changing working rolls. Summary of the invention

[0003] The utility model aims to provide a pin shaft anti-dropping device to prevent the pin shaft of the transverse floor from falling off.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A pin shaft anti-slip device comprises a baffle, an inlet side support, and an outlet side support. One end of the inlet side support is fixedly connected to the inlet side floor, and one end of the outlet side support is fixedly connected to the outlet side floor. The other ends of the inlet side support and the outlet side support are both provided with through holes for installing the pin shaft. One end of the baffle is rotatably connected to the inlet side support or the outlet side support, and the other end can cover the shaft head of the pin shaft.

[0006] The inlet side support is an integrated structure, including a bottom plate and a slot plate. The bottom plate is vertically fixedly connected to the slot plate. The end of the slot plate is a groove-shaped structure, and a through hole is opened on the groove-shaped structure.

[0007] The inlet side support is an integrated structure, including a second bottom plate and a plug plate, wherein the second bottom plate is vertically fixedly connected to the plug plate, and the end of the plug plate is a protruding structure with a through hole.

[0008] The end of the baffle is rotatably connected to the inlet side support or the outlet side support via a rotating shaft.

[0009] The rotating shaft is fixedly connected to the inlet side support or the outlet side support.

[0010] The other end of the baffle is fixedly connected with a handle.

[0011] The baffle is an arc-shaped structure.

[0012] The inner diameter of the arc-shaped structure is between the outer diameter of the shaft head of the pin and the diameter of the shaft handle of the pin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The pin shaft anti-dropout device has a simple and reasonable structure, which can reliably connect the entrance side floor and the working side floor. The rotatable baffle plate is used to block the pin shaft to prevent the pin shaft from falling off, so that the transverse floor can run stably and save time for checking the pin shaft. In addition, there is no need to drill holes in the floor to connect the pin shaft, which ensures the strength of the floor. The entrance side support and the exit side support are used to connect the pin shaft to avoid damage to the floor due to misoperation. Once the pin shaft connection is damaged, the entrance side support and the exit side support can be directly replaced for easy maintenance. The baffle adopts an arc-shaped structure to facilitate the disassembly and assembly of the pin shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0028] Example 1

[0029] See Figure 1-Figure 6A device for preventing a pin shaft 5 from falling off comprises a baffle plate 3, an inlet side support 1 and an outlet side support 2, wherein one end of the inlet side support 1 is fixedly connected to the inlet side floor, and one end of the outlet side support 2 is fixedly connected to the outlet side floor. The other ends of the inlet side support 1 and the outlet side support 2 are both provided with a through hole 14 for installing the pin shaft 5, one end of the baffle plate 3 is rotatably connected to the inlet side support 1 or the outlet side support 2, and the other end can cover the shaft head of the pin shaft 5.

[0030] Example 2

[0031] On the basis of Example 1, an inlet side support 1 and an outlet side support 2 that can be plugged into each other are used. Specifically:

[0032] See Figure 3-Figure 4 The inlet side support 1 is an integrated structure, including a bottom plate 11 and a slot plate 12. The bottom plate 11 and the slot plate 12 are welded vertically to each other. The end of the slot plate 12 is a groove-shaped structure 13, and a through hole 14 is opened on the groove-shaped structure 13.

[0033] See Figure 5-Figure 6 The outlet side support 2 is an integrated structure, including a bottom plate 21 and a plug plate 22. The bottom plate 21 and the plug plate 22 are welded vertically to each other. The end of the plug plate 22 is a protruding structure 23, and a through hole is opened on the protruding structure 23.

[0034] The inlet side support 1 and the outlet side support 2 are arranged opposite to each other. When the inlet side floor and the outlet side floor move laterally, the protruding structure 23 is inserted into the groove-shaped structure 13 until the through hole on the protruding structure 23 coincides with the through hole 14 on the groove-shaped structure 13, and then the pin shaft 5 is inserted into the through hole 14 to complete the connection between the inlet side floor and the outlet side floor.

[0035] Example 3

[0036] On the basis of the embodiment 1 and the embodiment 2, a baffle 3 structure is adopted which is rotatable and convenient for assembly and disassembly.

[0037] See Figure 1-Figure 2 The end of the baffle 3 is rotatably connected to the inlet side support 1 or the outlet side support 2 through the rotating shaft 4. The rotating shaft 4 is fixedly connected to the inlet side support 1 or the outlet side support 2, and the baffle 3 can rotate around the rotating shaft 4. The head diameter of the rotating shaft 4 is larger than the diameter of the rotating shaft 4 body to prevent the baffle 3 from being separated from the rotating shaft 4 during the rotation process. Figure 7-Figure 8 , a handle 31 is welded to the other end of the baffle 3. The baffle 3 is an arc-shaped structure 32. The inner diameter of the arc-shaped structure 32 is between the outer diameter of the shaft head of the pin 5 and the diameter of the shaft handle of the pin 5. The baffle 3 is rotated so that the arc-shaped structure 32 can press the edge of the shaft head of the pin 5, which can prevent the pin 5 from falling off and facilitate the disassembly and assembly of the baffle 3. The handle 31 is fixed on the baffle 3, which is convenient for the hammer to apply force. The handle 31 can be directly hit with a hammer to rotate the baffle 3, which is conducive to operation in a narrow space.

[0038] The utility model has a simple and reasonable structure, can reliably connect the entrance side floor and the working side floor, utilizes the rotatable baffle plate 3 to block the pin shaft 5 to prevent the pin shaft 5 from falling off, makes the transverse floor run stably, and saves time for checking the pin shaft 5.

[0039] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
