backup pad

2, 2 tops in backup pad have

saddle bottom plate

3, 2 bottoms in backup pad have hydraulic motor 6, hydraulic motor 6's output and saddle bottom plate 3 are connected, hydraulic motor 6 drives saddle bottom plate 3 rotation, hydraulic motor 6 embeds there is the encoder that is used for measuring and control rotation angle, saddle bottom plate 3 surfaces have saddle 4, saddle 4 includes a plurality of saddles claw 41, saddles claw 41 is used for supporting coil of strip 8, be provided with position induction system 7 between backup pad 2 and the saddle bottom plate 3, position induction system 7 is connected with hydraulic motor 6's controller electricity.

In the preferred embodiment of the present invention, a rotary support seat 5 is provided between the support plate 2 and the saddle bottom plate 3.

The utility model discloses a preferred embodiment, the mounting hole has in the middle part of backup pad 2, the mounting hole top is connected with motor mounting panel 61, hydraulic motor 6 is connected in motor mounting panel 61 bottom.

In the preferred embodiment of the utility model, the output of hydraulic motor 6 is connected with spline housing 62, the bottom of spline housing 62 top and saddle bottom plate 3 is connected.

In the preferred embodiment of the present invention, the position sensing device 7 comprises a sensing plate 72 disposed outside the saddle bottom plate 3 and a plurality of proximity switches 71 disposed outside the support plate 2, wherein the sensing plate 72 is sensed or separated from the proximity switches 71 during the rotation of the saddle bottom plate 3.

In the preferred embodiment of the present invention, the number of the dry saddles 41 is four, each the surface of the saddle 41 has the saddle arc surface 42 of the slope, the saddle arc surface 42 is disposed in two opposite directions.

The working principle of the device is explained by taking the working angle of the steel coil steering table as +/-90 degrees as an example.

As shown in fig. 3, on the outer side of the support plate, there are 4 proximity switches 71 for detecting and controlling the first stop position, the first deceleration position, the second stop position and the second deceleration position of the saddle 4, respectively.

Supposing that the initial position of the saddle 4 is stop position one, when the steel coil 8 is placed on the saddle 4 and then sends a signal, the hydraulic motor 6 starts to work after receiving the signal, the saddle 4 and the steel coil 8 are driven to rotate, the hydraulic motor can preset the rotation angle and the rotation direction as required, and the whole motion process is stable and free of blocking due to the rotary support of the rotary support seat. When the sensing plate 72 on the side of the saddle bottom plate 3 rotates counterclockwise and passes the second deceleration position, the proximity switch 71 at the position sends a signal, and the hydraulic motor 6 starts to decelerate. When the sensing plate 72 on the side of the saddle bottom plate 3 rotates counterclockwise to the second stop position, the proximity switch at the position sends a signal, and the hydraulic motor 6 stops operating. To this end, the saddle 4 has supported the coil of steel 8 from the first stop position rotated 90 ° counterclockwise to the second stop position. Conversely, through the same action, the saddle 4 can also rotate clockwise by 90 ° from the second stop position to the first stop position.

When the saddle 4 passes through the deceleration position or the stop position, the proximity switch at the position sends a signal, and the signal of the proximity switch only plays a role of indicating that the saddle 4 is approximately close to the in-position, and the actual in-position condition of the saddle 4 is realized by means of an encoder arranged in the hydraulic motor 6. Therefore, the position of the proximity switch for sending the signal does not need to be particularly accurate, and even if the proximity switch cannot work normally, the steel coil 8 cannot rotate to be over-positioned, and the next process cannot be influenced.
