Detailed Description
In the following detailed description of the preferred embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific features of the invention, such that the advantages and features of the invention may be more readily understood and appreciated. The following description is an embodiment of the claimed invention, and other embodiments related to the claims not specifically described also fall within the scope of the claims.
Fig. 1 is a schematic structural diagram of a ladle transfer device, which comprises a ladle rotary platform 1, a support frame 2, a vertical lifting driving device 3, a horizontal movement driving device 4, a rotary driving device 5 and a rotary gear 6, wherein the vertical lifting driving device 3 and the horizontal movement driving device 4 are connected to the rotary platform 1 through the support frame 2, and the rotary driving device 5 is connected with the rotary platform 1 through the rotary gear 6.
The vertical lifting driving device 3 controls the vertical lifting of the rotary platform 1, the horizontal moving driving device 5 controls the horizontal side movement of the rotary platform 1, and the rotary driving device 5 controls the rotary platform 1 to rotate. The support frame 2 comprises a horizontal support frame and a vertical support frame, and the rotary platform 1 and the horizontal support frame are integrally installed on the vertical support frame.
The rotary platform 1 is used for loading a ladle, and the rotary platform 1 and the ladle can be connected in a clamping pin manner or in other connection manners. The rotary platform 1 can be driven by the vertical driving device 3, the horizontal driving device 4 and the rotary driving device 5 to perform actions such as lifting, translation, rotation and the like, and can also perform two-by-two combination or three actions of the actions simultaneously.
The support frame 2 may be designed in an L-shape as shown in fig. 1, and is divided into two parts, i.e., the horizontal support frame and the vertical support frame. The support frame can be designed into T-shaped or inverted T-shaped and other different shapes according to different operation requirements, and the material of the support frame is not limited as long as the characteristics of bearing requirements and difficult deformation can be met. The support frame 2 is used for supporting the rotary platform and bearing the movement of the rotary platform 1 under the action of driving force.
Further, as shown in fig. 1, the vertical lift driving device 3 includes a vertical hydraulic cylinder 31 and a guide frame 32, the guide frame 32 includes a transverse fixing beam 322, a longitudinal fixing beam 321 and a vertical guide idler 323, the transverse fixing beam 322 and the longitudinal fixing beam 321 form a rigid high-strength rectangular structure of the guide frame 32, and the vertical guide idler 323 is located at an opposite angle and is non-rigidly connected to the support frame 2.
When lifting and lowering the ladle are needed, the vertical hydraulic oil cylinder 31 outputs power, the output power acts on the vertical guide carrier roller 323 of the guide frame 32, the vertical guide carrier roller 323 moves up and down along the guide frame 32 in the vertical direction, the vertical guide carrier roller 323 acts on the bracket 2, and the bracket drives the rotary platform 1 to move up and down.
Further, the vertical lift driving device 3 further includes a hydraulic lock 34, and the hydraulic lock 34 is configured to enable the vertical hydraulic cylinder 31 to hover at any position within the vertical moving stroke.
The hydraulic lock is used for keeping the oil cylinder in a static state. In the ladle lifting process, when the ladle needs to be suspended at a certain height, the hydraulic lock is started, the vertical hydraulic oil cylinder 31 is changed from a dynamic state to a static state under the action of the hydraulic lock, and therefore the vertical guide carrier roller 323, the support frame 2, the rotary platform and the ladle are all suspended in the vertical direction.
Further, the vertical lifting driving device 3 further includes a limiting block 33, and the limiting block 33 bears a load in the vertical direction during the ladle transferring process.
When the ladle transfer device bears the ladle and is transferred by a vehicle or in other modes, the ladle does not need to be lifted in the vertical direction. The vertical load is carried by the vertical hydraulic cylinder 31, which may cause rapid aging and even damage of the vertical hydraulic cylinder 31, and may also result in unstable output power of the cylinder during the transfer operation. When the transfer operation is needed, the limiting block 33 of the vertical lifting driving device 3 is opened, and the load in the vertical direction is borne by the limiting block, so that the direct stress of the vertical hydraulic oil cylinder 31 is avoided. Or when the rotary platform 1 rises to the height required by the operation, the hydraulic lock 34 acts on the vertical hydraulic oil cylinder 31 to enable the vertical hydraulic oil cylinder 31 to hover at the operation height, and the limit block 33 is started to enable the vertical hydraulic oil cylinder 31 to bear the load in the vertical direction when hovering.
Furthermore, the vertical hydraulic oil cylinder 31 can adopt a single-acting multi-stage oil cylinder, the lifting moment of the single-acting multi-stage oil cylinder is larger than 25 tons, the vertical moving distance is 1850mm, and the moving speed is 0-200 mm/sec. The setting of the moving speed enables the vertical lifting of the ladle to be more stable, the setting of the vertical moving distance enables the vertical lifting operation of the ladle to be more flexible, and the setting of the lifting moment enables the selectable range of the weight of the ladle to be wider.
Further, the horizontal movement driving device 4 comprises a horizontal hydraulic oil cylinder 41 and a horizontal movement sleeve type guide rail 42, and the sleeve type guide rail 42 bears radial load in the horizontal movement process of the rotary platform 1, so that the horizontal movement of the rotary platform is stable and reliable.
The horizontal guide shaft of the horizontal moving sleeve type guide rail 42 is rigidly connected with the support frame 2, and can adopt a bolt connection or other rigid connection modes as required.
When the ladle needs to move horizontally, the horizontal hydraulic oil cylinder 41 outputs power to act on the horizontal guide shaft of the horizontally moving sleeve type guide rail 42, and then the support 2, the rotary platform 1 and the ladle are driven to move horizontally. During horizontal movement, radial loads are taken up by the telescopic guide tracks 42. Because the bracket 2 and the vertical lifting driving device 3 are not rigidly connected by the vertical guide carrier roller 323 through a diagonal positioning mode, the horizontal movement of the support frame 2 cannot be limited at the moment.
Furthermore, the horizontal hydraulic oil cylinder 41 can adopt a double-acting equal-stroke oil cylinder, the transverse accurate stroke of the double-acting equal-stroke oil cylinder is 300mm, and the horizontal moving speed is 0-150 mm/sec. The double-acting equal-stroke oil cylinder is selected, so that the horizontal movement process of the ladle can be kept stable, the setting of the stroke is accurate, and the translation of the ladle is more flexible.
Further, the slewing drive device 5 is driven by a hydraulic oil cylinder.
As shown in fig. 1, the rotation driving device 5 may be installed between the support 2 and the rotation platform 1, may be fixedly installed on a transportation vehicle, or may be installed at any position that does not affect the horizontal movement and vertical lifting of the rotation platform 1.
When the ladle needs to perform rotary motion, the hydraulic oil cylinder of the rotary driving device 5 outputs power to act on the rotary gear 6, the rotary gear 6 drives the rotary platform 1 to perform rotary motion, and the rotary platform 1 drives the ladle to perform rotary motion.
Further, the hydraulic oil cylinder of the slewing drive device 5 can adopt a bidirectional quantitative motor to drive the gear 6, so that the slewing stroke is 316 degrees clockwise/anticlockwise, and the slewing speed is 15 degrees/sec. The bidirectional quantitative motor is adopted to control the rotation speed, so that the ladle rotation action is stable, and the rotation operation is more flexible due to a larger rotation stroke.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim.
