Detailed Description

The following describes embodiments of the present invention with reference to the drawings. While many details are set forth in the following description, these are for illustrative purposes and are not intended to be limitations of the invention. On the basis of the present description, a person skilled in the art will be able to vary within the scope defined by the claims.

Referring to fig. 1, a ladle rotating apparatus 100 includes a driving arm 110, a push rod 120, and a ladle flipping member 130.

As shown in fig. 1, the driving arm 110 is connected to the first fixed mount 1 and forms a first revolute pair 10, that is, the driving arm 110 can rotate relative to the first fixed mount 1. In one example, the driving arm 110 may rotate around a first axis fixed to the first stationary support 1.

In the embodiment shown in fig. 1, a drive disk 300 is also included and is configured to rotate coaxially with drive arm 110. Further, drive disk 300 is fixed to drive arm 110 such that the drive disk rotates in unison with the drive arm. In this embodiment, the drive arm 110 is arranged in the diameter direction of the drive disc 300, i.e. the drive arm 110 is fixed to the drive disc 300 across the entire diameter. This allows a large torque to be transmitted to the drive arm via the drive plate.

More specifically, referring to fig. 1 and 3, a plurality of mounting holes 310 are provided in the circumferential direction of the drive disk 300, and these mounting holes 310 are symmetrical with respect to the axis of the drive disk. The drive arm 110 is fixed to the drive disc 300 by at least one pair of symmetrical mounting holes 310, i.e. two mounting holes symmetrical about an axis. In the embodiment of fig. 1, the drive arm is secured by two pairs of symmetrical mounting holes, however, depending on the size of the drive arm and the particular application, securing by more mounting holes may be employed. This allows the relative orientation of the drive arms to be adjusted as desired, for example, depending on the range of rotation and position of the bale turning member. As can be appreciated by those skilled in the art, the driving arm is provided with mounting holes for mounting and fixing the driving arm.

The drive arm and/or the drive disk may be rotated by a motor. The output shaft of the motor may be connected directly to the rotational shaft of the drive arm and/or drive disk, or may also be connected via a gear reduction box. The type of motor may be any suitable type of motor.

Although in the above described embodiment a specific way of securing the drive arm is described, it will be appreciated by those skilled in the art that other securing means may be used. For example, in some instances, the drive plate may not be employed. Alternatively, in another example, the revolute pair may be provided at one end of the drive arm.

In addition, although in the illustrated embodiment, the rotating disk is configured in a circular shape. However, in other embodiments, the rotating disk may be configured in any suitable shape as long as it can rotate about the rotating shaft. The distribution of the mounting holes is not limited to the circumferential distribution as long as it is symmetrical about the axis, and the distance between the symmetrical mounting holes may be determined according to the length of the driving arm and the arrangement of the fixing hole sites thereof.

As shown in fig. 1, the front portion of the turning-up member 130 is connected to the second fixed mount 2 and forms the second revolute pair 20, i.e., the turning-up member 130 can relatively revolve with respect to the second fixed mount 2. In one example, the turnup member 130 may be configured to rotate about a second axis on the second stationary support 2.

Further, in the embodiment shown in fig. 1, the first and second fixed mounts are configured as part of a stand 200, wherein the axes of the first 10 and second 20 revolute pairs are parallel to each other and form a fixed distance therebetween. The distance mentioned here refers to the distance on the plane where the axes of the two revolute pairs are located, and can be interpreted as the distance between two parallel lines on the same plane. In other examples, the first and second fixed mounts may be two separate components.

The term "front" in relation to the turn-up member herein refers to a portion of the turn-up member which is closer to the side of the centrifuge when mounted, and correspondingly, the term "rear" in relation to the turn-up member refers to a portion of the turn-up member which is further from the side of the centrifuge when mounted. It will be understood by those skilled in the art that the location of the particular connection point between the front portion of the turn-up member and the second shaft may be determined according to the particular application environment, and the locations shown in the drawings of this specification are exemplary only and not limiting.

In one embodiment, the turning member 130 includes a fanning pack 132, wherein a front portion of the fanning pack is coupled to the second stationary bracket and forms the second revolute pair. In addition, in this example, the upper end of the push rod 120 is connected to the bottom of the rear portion of the fanning pack 132 and forms the third revolute pair 30. The terms "front" and "rear" are used herein to refer to the portion of the fan pack adjacent to or remote from the side of the centrifuge, respectively, as defined above for the tipping member. The term "upper end of the push rod" herein means an end of the push rod 120 which is positioned higher in the vertical direction after being installed.

Also, in this example, the push rod 120 is attached to the outside of the bottom of the fanned pack, i.e., the outer surface of the bottom, as would be understood by one skilled in the art. Referring to fig. 2, similarly, the bottom outer side of the fan-shaped bag may be provided with a third fixed support 3 on which a third shaft is fixedly mounted, and the upper end of the push rod 120 and the third shaft form the third revolute pair 30.

In another embodiment, the turning member 130 includes a fanned pack 132 and a turning frame 134, wherein a front portion of the turning frame 134 is coupled to the second stationary bracket and forms the second revolute pair. In this example, the upper end of the push rod 120 is attached to the bottom of the rear portion of the turnup 134 and forms the third revolute pair 30. As shown in fig. 2, the bottom surface of the tipping frame 134 can be provided with the third fixed support 3, on which the third shaft can be mounted, and the upper end of the push rod 120 and the third shaft form the third revolute pair 30.

In this example, the terms "front portion of the tip-up stand" and "rear portion of the tip-up stand" refer to the portion of the tip-up stand that is closer to or farther from the side of the centrifuge, respectively, after installation. The term "upper end of the push rod" here is the same as the term used in the foregoing.

In addition, in this example, as previously described, the tipping frame 134 is fixedly connected to the second fixed support, and the fan-shaped package 132 is placed on the tipping frame 134 and is kept stable by its own weight. Also, the fanning pack 132 is provided at the front thereof with an anti-slip hook structure 136 configured to hook on the aforementioned turning shaft or the turning frame 134.

Further, the distance between the position where the push rod 120 is connected to the turn-up member 130 and the highest liquid level of the turn-up member 130 is the largest. The highest liquid level of the ladle turning component refers to the liquid level of the static molten iron when the fan-shaped package carries the maximum amount of molten iron. Since in practice the molten iron is always in motion and the fan pack does not always contain the maximum amount of molten iron, depending on the amount of molten iron required for casting, when the fan pack is provided with a scale or mark indicating the maximum load, this mark corresponds to the maximum level, i.e. the maximum level.

The expression that the distance from the highest liquid level is maximum means that the distance from the third revolute pair to the highest liquid level of the ladle turning member is maximum. In the utility model, the third revolute pair is parallel to the highest liquid level. Thus, the term "distance from the highest liquid level" is to be interpreted as the distance between a parallel line and a plane. This distance is the largest, which means that the third revolute pair sets the lowest point of the ladle tilting member in the vertical direction, so that when the push rod 120 lifts the ladle tilting member 130 to be tilted, more molten iron can be poured out of the ladle fan 132 at a relatively small tilting angle. The dotted line in fig. 2 shows the position of the push rod 120 when the lift-up turn-up member 130 is turned over.

In addition, the shape of the fan-shaped package 132 may be set according to a specific application environment.

As also shown in fig. 2, the end of the drive arm 110 is connected to the lower end of the push rod 120 and forms a fourth revolute pair 40. That is, the driving arm and the push rod may be relatively rotated. The term "lower end" herein means an end of the push rod 120 which is installed to be lower in a vertical direction.

In the present invention, the length of the push rod 120 can be adjusted. In the exemplary embodiment shown in fig. 1 and 2, the length of the push rod 120 is adjusted such that the distance between the third gear pair 30 and the fourth gear pair 40 is equal to the distance between the first gear pair 10 and the second gear pair 20. In this example, the length of the push rod is the distance between the axes of rotation of the upper and lower ends of the push rod.

In the present invention, the axes of the first, second, third and fourth revolute pairs are parallel to each other. The distance between the revolute pairs is the distance between the axes of the revolute pairs and can be determined by reference to the distance between two parallel lines. In addition, the distance between the first rotating pair and the third rotating pair is equal to the distance between the second rotating pair and the fourth rotating pair. Thus, the first, second, third and fourth revolute pairs constitute four revolute pairs of the four-bar linkage.

The push rod 120 may be configured to include an outer sleeve 122 and an inner rod 124. Wherein the outer sleeve 122 and the inner rod 124 are axially slidable relative to each other to adjust the overall length of the push rod. Also, the outer sleeve 122 and the inner rod 124 may be relatively fixed in a plurality of positions such that the overall length of the push rod 120 remains constant when the two are relatively fixed. In one example, the outer sleeve 122 and the drive arm 110 form the fourth revolute pair 40, and the inner rod 124 and the turnup member 130 form the third revolute pair 30. Alternatively, in another example, the outer sleeve and the turnup member may form a third revolute pair, and the inner rod and the drive arm may form a fourth revolute pair.

In the embodiment of fig. 1 and 2, the drive arm 110, the pusher 120, and the bale turning member 130 are configured as a parallelogram mechanism, such that the rotational angles of the drive arm and bale turning member are synchronized. In other embodiments, a non-parallelogram four-bar linkage may be constructed.

Also, those skilled in the art will appreciate that the above described rotary pair includes a rotary shaft, wherein the rotary shaft may be configured as part of either of the two rotary members forming the rotary pair, or as a separate component. Depending on the specific application, the shaft may or may not have a bearing, and the shaft itself may or may not rotate. In addition, the relative rotation range between the two rotating parts of the rotating pair, namely, the rotatable angle range, can be determined according to the specific application environment.
