Description

Technical Field

[0001] The utility model relates to a novel slab piling table, and relates to the technical field of slab roller conveyors in the metallurgical continuous casting system. Background Art

[0002] During the slab continuous casting production process, various surface defects such as transverse and longitudinal cracks, subcutaneous pinholes, scratches, and depressions will appear on the surface of the continuous casting billet, thus affecting the quality of the final product. Therefore, if there are small defects on the surface of the casting billet and it is transferred to the rolling process without treatment and rolled into finished products, the harm of the defects will be further expanded, and in serious cases, it will directly cause the rolled materials to be rejected.

[0003] When surface defects are found on the billet, or regular sampling inspections are required by the process, the hot red billet must be conveyed away from the roller path. The existing piling table is used to receive the billet in blocks through a lifting tray. An oil cylinder and a connecting rod lifting mechanism are arranged at the bottom of the lifting tray. The oil cylinder drives the ejector rod to drive the tray to lift. Four connecting rods are movably connected with four rockers to assist in supporting the tray. However, during the lifting process of the existing piling table, due to the inevitable uneven overall force, the four connecting rods and the rockers are not synchronized, resulting in tilting, jamming during the lifting process, and in serious cases, the red billet slides off, causing safety accidents.

Detailed implementation manners

[0022] Refer to Figures 1-6 As shown, the technical solution adopted in this detailed implementation manner is: It includes a pallet 1, a lifting oil cylinder 2 is arranged at the center below the pallet 1, the lifting oil cylinder 2 is movably connected to the pallet 1 through an ejector rod 4, and a first auxiliary stabilizing mechanism 5 and a second auxiliary stabilizing mechanism 6 are arranged on both sides of the lifting oil cylinder 1. Both the first auxiliary stabilizing mechanism 5 and the second auxiliary stabilizing mechanism 6 include two sets of stabilizing mechanisms. An auxiliary ejector rod 8 is arranged at the top of each set of stabilizing mechanisms and is movably connected to the pallet 1. In the traditional slab stacking table mechanism, the lifting is mainly carried out by an oil cylinder, and then the auxiliary support is carried out through an independent ejector rod and a rocker. When the pallet is unevenly stressed, the pallet will tilt, resulting in jamming during lifting. Seriously, the green billet will slide off. Therefore, in this embodiment, two sets of auxiliary stabilizing mechanisms are provided. The two sets of auxiliary stabilizing mechanisms are synchronous mechanisms. When the pallet tilts, the two sets of auxiliary stabilizing mechanisms will lift synchronously to ensure that the pallet remains horizontal, effectively preventing the tilting situation during the stacking process and ensuring safe production;

[0023] Specifically, the first auxiliary stabilizing mechanism 5 includes a herringbone rocker 52. A connecting rod 7 is movably arranged on the two herringbone rockers 52. The herringbone rocker 52 includes an upper rocker 521 and a lower rocker 522. The lower rocker 522 is movably connected to the connecting rod 7. The first auxiliary stabilizing mechanism 5 further includes a stabilizing shaft seat 51. A connecting shaft 53 is arranged on the first shaft seat 51, and the connecting shaft 53 is fixedly connected to the herringbone rocker 52. In this embodiment, a rocker is arranged on the connecting shaft of the auxiliary stabilizing mechanism. Among them, the first auxiliary stabilizing mechanism is the main synchronous mechanism, and the rocker arranged on it is a herringbone rocker. The lower part of the herringbone rocker is a lower rocker, and the two lower rockers are connected by a connecting rod. When any herringbone rocker swings, it will drive the other herringbone rocker to swing synchronously, and under the action of the connecting shaft, it will drive the second auxiliary stabilizing mechanism to swing synchronously. When the second auxiliary stabilizing mechanism tilts on one side, it will also drive the first auxiliary stabilizing mechanism to swing synchronously. After a green billet is conveyed, the pallet descends, and the second green billet continues to be conveyed and stacked on top of the first one, thus realizing the stable lifting of the pallet.

[0024] More specifically, the second auxiliary stabilizing mechanism 6 includes a second shaft seat 61 and a cross-shaped rocker 62. The second shaft seat 61 is movably connected to the connecting shaft 53, and the cross-shaped rocker 62 is fixedly connected to the connecting shaft 53. In this embodiment, the second auxiliary stabilizing mechanism is of a traditional structure without a connecting rod provided thereon to prevent interference when there are connecting rods on both sides. Therefore, in the case where a connecting rod is provided on one side, the first and second auxiliary stabilizing mechanisms are connected by the connecting shaft to operate synchronously, thereby achieving the effect of stable lifting and lowering.

[0025] More specifically, lifting brackets are provided at both ends of the tray 1. V-shaped guiding slide rails 10 are provided on both sides of the lifting brackets. At positions corresponding to the V-shaped guiding slide rails 10, V-shaped guiding chute seats 3 are provided. The V-shaped guiding chute seats 3 are fixed to the external frame. The front end guide rails of the V-shaped guiding slide rails 10 are slidably connected in cooperation with the guide groove of the V-shaped guiding chute seats 3. To ensure the stability of lifting and lowering, V-shaped guiding chute seats are provided on the external frame, and V-shaped guiding slide rails are provided on the lifting brackets of the tray. The V-shaped guiding slide rails are slidably engaged with the V-shaped guiding chute seats to prevent lateral displacement during the lifting process and improve the stability of operation.

[0026] More specifically, a stroke control rod 11 is provided on one side of the bottom of the tray 1. Two stroke switches 12 fixed to the frame are provided outside the stroke control rod 11 perpendicular to the stroke direction. In this embodiment, the two stroke switches are used to limit the maximum and minimum strokes of the oil cylinder, prevent over-lifting and retracting, and prevent damage to the equipment. The top stroke switch controls the equipment to stop running when the end piece of the stroke control rod touches the switch during the upward movement, and the bottom stroke switch works on the same principle, thereby achieving the self-protection of the equipment.

[0027] More specifically, scales are provided on the stroke control rod 11. The specific position of the end piece on the stroke control rod can be adjusted through the scales, and the positions of the stroke switches are adjustable, thereby adjusting the stroke range of the tray to ensure that the equipment operates within a safe stroke range.

[0028] More specifically, spherical plain bearings are provided at both ends of the ejector rod 4. By providing spherical plain bearings, the deviation of non-collinear movement can be better eliminated, and the tray can be prevented from being jammed due to upward and downward forces.

[0029] Working principle of the utility model: One side of the tray 1 is adjacent to the roller path. When the red billet 9 is not being transported, the tray 1 can be adjusted to be flush with the roller path. When the transportation of the red billet 9 starts, the pusher pushes the red billet onto the tray 1. When the red billet 9 is pushed to the designated position, the pusher stops pushing and returns. At this time, the oil cylinder 2 starts to contract, driving the tray 1 to move downward. During the downward movement of the tray 1, the auxiliary ejector rod 8 is pressed to move downward, which drives the V-shaped rocker 52 and the linear rocker 62 to swing. Under the action of the connecting rod 7, the two V-shaped rockers 52 will swing synchronously. Since the V-shaped rocker 52 and the linear rocker 62 are fixed on the connecting shaft 53, the connecting rod 7 restricts the two V-shaped rockers 52, enabling the four rockers to swing synchronously. The four rockers provide auxiliary support for the tray 1. At the same time, during the lifting and lowering process, the front guide rail of the V-shaped guiding slide rail 10 is slidably connected with the guide rail groove of the V-shaped guiding chute seat 3. With the cooperation of the first and second auxiliary stabilizing mechanisms, the stable lifting and lowering of the tray 1 are ensured, and no skewing occurs, ensuring safe production.

[0030] The above is only used to illustrate the technical solution of the utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, shall be covered by the scope of the claims of the utility model.
