Description

Technical Field

[0001] The utility model relates to the technical field of medium and thick plate processing, in particular to a medium and thick plate working roller platform cover plate installation device. Background Art

[0002] The working roll changing platform of the rough rolling mill of the 3800 production line consists of two intermediate bridges, namely the front bridge and the rear bridge. The front bridge is close to the rolling mill and is a welded special-shaped structure. A set of flat rails and V-shaped rails are laid on it to connect with the fixed rails in the frame. Two sets of flat rails and V-shaped rails are laid on the rear bridge, and two sets of working roll groups can be placed at the same time. The flat rails and V-shaped rails in the rear bridge are aligned with the flat rails and V-shaped rails of the front bridge through the transverse device to complete the replacement of the old and new working roll groups. The track of the working roll changing push-pull cylinder running wheel is also laid on the intermediate bridge to complete the operation of the working roll group entering and exiting the frame.

[0003] The connection between the middle bridge and the inlet side frame and the outlet side frame is completed through the V-shaped seat on the frame. The hydraulic cylinder is connected to the inlet side frame through a pin to complete the lateral movement of the middle bridge, thereby completing the alternating connection between the two sets of tracks and the front bridge track.

[0004] In the above-mentioned prior art, the hole on one side caused by each lateral movement is covered and filled by multiple cover plates. However, due to the limited space on site, the length of the two cover plates is less than the length of the middle bridge, and there is still a hole in a part, which poses a risk of falling. In this regard, we propose a cover plate installation device for medium and thick plate working roller platform. Utility Model Content

When the rolling platform performs a roll changing operation, rapid folding can be performed. After the roll changing is completed, the first folding plate and the second folding plate are quickly reset, thereby quickly covering the cavity and improving the safety of use.

[0014] Furthermore, a sliding rod is transversely inserted into the bottom end of the second folding plate, and both ends of the sliding rod slide through the side wall of the mounting base.

[0015] Through the above technical solution: the sliding rod is used to guide the movement trajectory of the second folding plate, so as to prevent the second folding plate from shaking when folding, thereby improving the stability of the folding process.

[0016] Preferably, a slide groove is provided at the intersection of the mounting base and the slide rod, and both ends of the slide rod are slidably inserted into the slide groove.

[0017] Through the above technical solution: the slide groove is used to guide the movement of the slide rod.

[0018] The beneficial effects of the utility model are:

[0019] 1. Synchronous transmission and linkage effect: Through the coordinated action of sprockets, transmission chains, rotating shafts, gears and other devices, the synchronous transmission and linkage effects between the components are achieved, ensuring the stability and efficiency of the device during operation.

[0020] 2. Fast folding and resetting: The second rotating rod drives the connecting rod to rotate the first folding plate, thereby achieving synchronous folding between the folding plates.

At the same time, after the roll change is completed, the first folding plate and the second folding plate can be quickly reset to quickly cover the hole, improving safety in use.

[0021] 3. Stability of the folding process: Through the design of the slide rod and the slide groove, the movement trajectory of the second folding plate is guided to prevent shaking during the folding process, ensure the stability of the folding process, and further improve operational safety.
