Description

Technical Field

[0001] This utility model belongs to the field of flipping device technology, and specifically relates to a vertical flipping mechanism. Background Technology

[0002] There are many types of tilting devices. According to their size, they can be divided into large, medium and small. Generally, steel companies use more large tilting devices.

[0003] Guides are essential components of rolling mill production lines. Installed before and after the roll passes, they help the workpiece enter and exit the roll passes accurately and stably in a predetermined direction and state. Some guides require a 90° rotation before maintenance and installation. Rotation of these guides utilizes a rotation device, a pry bar, or an overhead crane. Traditional guide rotation methods have the following drawbacks: 1. Low efficiency of manual operation: The flipping process relies on manual operation or hoisting, and each flipping takes about 10-15 minutes, which affects continuous production; 2. Insufficient positioning accuracy: The mechanical limit structure is simple, and after it is flipped into place, it is easy to be displaced due to vibration, resulting in a misalignment between the guide and the roll of ≥2mm; 3. High safety risks: Manual contact with moving parts poses a risk of pinching or crushing injuries; 4. Low level of automation: It cannot be linked with the rolling mill control system and is difficult to adapt to the high-speed rolling rhythm.

[0004] 5. The inertial force generated during the movement of the tilting device is difficult to balance, and there are also dead points, posing a potential risk of equipment jamming.

[0005] Therefore, there is an urgent need to design an efficient, precise, and safe flipping mechanism to meet the automation requirements of modern steel rolling production lines. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a vertical flipping mechanism that eliminates the risk of equipment jamming.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A vertical tilting mechanism includes a vertical tilting platform, a fixed frame, an arc-shaped connecting rod, an arc-shaped rack, a bearing housing, a gear shaft, and a reduction motor. The vertical tilting platform is mounted on the fixed frame, and its corners are movably connected to the fixed frame. The two side platforms of the vertical tilting platform are movably connected to the two ends of the arc-shaped connecting rod, respectively. An arc-shaped rack is fixedly connected to the arc-shaped connecting rod, and the arc-shaped rack meshes with the gear shaft. The gear shaft is connected to the bearing housing and is driven to rotate by the reduction motor.

[0008] The corner of the vertical flipping platform is connected to a hinge plate, which is movably connected to the fixed frame via a pin.

[0009] The bottom of both sides of the vertical flipping platform is connected to a connecting rod base, which is movably connected to the arc-shaped connecting rod via a pin.

[0010] The vertical flipping platform is a welded structure of pipe fittings and steel plates.

[0011] The fixing frame is a frame structure, and buffer rubber blocks are provided on the upper frame of both sides.

[0012] A mounting base plate is fixedly connected to the arc-shaped connecting rod, and an arc-shaped rack is bolted to the mounting base plate.

[0013] The geared motor is connected to the bottom of the fixed frame via a motor bracket.

[0014] Compared with existing technologies, the beneficial effects of this utility model are: 1. This utility model adopts an arc-shaped rack and pinion shaft transmission mechanism, which eliminates the risk of equipment jamming, reduces manual intervention and lowers operational safety risks, and enables the parts to rotate 90°.

[0015] 2. The vertical flipping platform of the pipe fittings and steel plate welded structure of this utility model facilitates the removal of debris and avoids uneven placement of parts or scratches on the surface of parts. Attached Figure Description
