Description

Technical Field

[0001] This utility model relates to a mechanism for preventing the trolley from derailing during roll changing in a six-roll aluminum cold rolling mill. Background Technology

[0002] Currently, cold rolling mills require roll changing operations during operation. However, due to insufficient space in the mill and inadequate tracks for the roll changing trolley, an extended movable track is generally required when changing support rolls. Without this movable track, the roll changing trolley is prone to overshooting and falling off the track when moving backward. Utility Model Content

[0003] This utility model improves upon the above-mentioned problems. Specifically, the technical problem to be solved by this utility model is to provide a mechanism for preventing the roll changing trolley of a six-roll aluminum cold rolling mill from derailing by setting a block at the outer end of the track to prevent the roll changing trolley from moving too far and derailing.

[0004] This utility model is constructed as follows: it includes a roller changing car, a worktable, and a track set on the worktable. The roller changing car can move along the track. An anti-derailment mechanism is provided at the outer end of the track. The anti-derailment mechanism includes an arc-shaped blocking surface extending laterally and upward along the outer end of the track.

[0005] Furthermore, the anti-derailment mechanism includes a base plate, with support plates arranged in front and behind on the side of the base plate away from the roller changing car. An arc-shaped baffle is provided on the side of the two support plates near the roller changing car, and the side of the arc-shaped baffle away from the support plate is connected to the base plate.

[0006] Furthermore, the bottom plate is provided with front and rear clamping plates on the side away from the roller changing car, and a groove is formed between the two clamping plates. The shape of the groove matches the shape of the upper part of the track.

[0007] Furthermore, the bottom plate has an inclined surface at one end near the roller changing car.

[0008] Furthermore, a pull handle is provided on the side of the base plate away from the roller changing car.

[0009] Furthermore, the top two sides of the card slot are provided with rounded corners.

[0010] Furthermore, the upper end of the arc-shaped blocking surface is higher than the lower end of the arc-shaped blocking surface.

[0011] Compared with existing technologies, this utility model has the following advantages: The device has a simple structure, reasonable design, and is easy to use. By installing the anti-derailment mechanism at the outer end of the track, it prevents the roller changing car from overshooting and falling off the track. Specifically, the anti-derailment mechanism's slot is pushed into and locked along the outer end of the track, with the base plate contacting the track surface. At this time, the anti-derailment mechanism forms a triangular structure, and the arc-shaped blocking surface creates a blocking effect on the roller changing car wheel. The triangular force is transmitted downwards to the track, ensuring the stability of the anti-derailment mechanism. When the roller changing car wheel presses down, the downward force makes the anti-derailment mechanism increasingly tighter. Furthermore, a pull handle is added to the tail of the anti-push mechanism for easy removal when not in use. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] Example: Figures 1-4 As shown in this embodiment, a mechanism for preventing the roll changing trolley of a six-roll aluminum cold rolling mill from derailing is provided. The mechanism includes a roll changing trolley 1, a worktable 2, and a track 3 set on the worktable. The roll changing trolley can move along the track. An anti-derailment mechanism 4 is provided at the outer end of the track. The anti-derailment mechanism includes an arc-shaped blocking surface 41 extending laterally and upward along the outer end of the track.

[0015] In use: The anti-derailment mechanism is installed on the outer end of the track to prevent the roller changing car from overshooting and falling off the track. Specifically, the anti-derailment mechanism is pushed into the slot along the outer end of the track and locked in place. The base plate contacts the track surface, at which point the anti-derailment mechanism forms a triangular structure. The arc-shaped blocking surface provides a blocking effect on the roller changing car wheel, and the force is transmitted downwards to the track through the triangular shape, ensuring the stability of the anti-derailment mechanism. When the roller changing car wheel presses down, the downward force makes the anti-derailment mechanism tighten further. In addition, a pull handle is added to the tail of the anti-push mechanism for easy removal when not in use.

[0016] In this embodiment of the utility model, the anti-derailment mechanism includes a base plate 42, and support plates 43 are provided in front and behind the side of the base plate away from the roller changing car. An arc-shaped baffle 44 is provided on the side of the two support plates close to the roller changing car. The side of the arc-shaped baffle away from the support plate is connected to the base plate. The connection between the arc-shaped baffle and the base plate can be smoothly transitioned.

[0017] In this embodiment of the utility model, the bottom plate is provided with a front and rear clamping plate 45 on the side away from the roller changing car, and a clamping groove 46 is formed between the two clamping plates. The shape of the clamping groove matches the shape of the upper part of the track.

[0018] In this embodiment of the utility model, the bottom plate has an inclined surface 47 at one end near the roller changing car.

[0019] In this embodiment of the invention, a pull handle 48 is provided on the side of the base plate away from the roller changing car.

[0020] In this embodiment of the utility model, the top two sides of the card slot are provided with rounded corners 49.

[0021] In this embodiment of the invention, the upper end of the arc-shaped blocking surface is higher than the lower end of the arc-shaped blocking surface.
