Description

Technical Field

[0001] The utility model relates to a novel slab off-line steel pusher, and relates to the technical field of slab roller conveying equipment of a metallurgical continuous casting system. Background Art

[0002] After the metallurgical continuous casting is formed, the slab is flame cut to a certain size and then conveyed in sections by rollers. The conveyed slab is a red-hot slab. During the slab continuous casting production process, various surface defects such as horizontal and vertical cracks, subcutaneous pinholes, scratches, and depressions will appear on the surface of the continuous casting slab. If the surface defects on the ingot are not treated, they will be directly transferred to the steel rolling process and rolled into finished products. The defects will be further expanded. In severe cases, the rolled products will be directly scrapped.

[0003] When surface defects are found on the billet, or when regular sampling is required due to process requirements, the hot billet must be transported off-line from the roller table, sometimes a single piece off-line, or multiple pieces stacked off-line;

[0004] At this time, the steel pusher is driven by the oil cylinder, generating a thrust perpendicular to the forward direction of the red billet conveying, and the pusher head contacts the side end face of the red billet, with an effective stroke of 3455mm. Under the force, the red billet leaves the roller conveyor line and falls into the symmetrical point of the conveyor line, and the lifting pallet is carried out in blocks. Then the crane hook group descends and lifts the billet for transfer.

[0005] However, the existing offline pusher lacks guiding and protecting mechanisms. During the pushing process, due to the heavy weight of the slab and the long-term offset and wear of the push rod connections, the pusher cart on the red slab pusher has been seriously offset. During the retraction process, the pusher often gets stuck and cannot be retracted into place, affecting production. Frequent maintenance also increases the workload of operators, which is not conducive to improving production efficiency. When the pusher is seriously offset, the pusher head may tilt and fall off, causing safety accidents, which is not conducive to safe production. Utility Model Content

DETAILED DESCRIPTION

[0024] See also Figure 1-7As shown, the technical solution adopted in this specific implementation is: it includes a steel pusher 1 and a pusher head 2. The pusher head 2 is arranged at the front end of the steel pusher 1. Wheels 3 are arranged on both sides of the rear end of the steel pusher 1. The wheels 3 are rollingly connected to the track boxes 9 on both sides. Adjustment guide mechanisms 6 are arranged on both sides of the front end of the steel pusher 1 near the pusher head 2. The adjustment guide mechanism 6 includes a side guide wheel assembly 7 and a disc spring assembly 8. The disc spring assembly 8 is arranged on the steel pusher 1. The side guide wheel assembly 7 is arranged at the top of the disc spring assembly 8 and extends out of the steel pusher 1 and is rollingly connected to the track box 9. In this embodiment, adjustment guide mechanisms are arranged on both sides of the front end of the steel stacking car, and are arranged behind the pusher head. When the pusher head is affected by the force of the red blank at the front end, When deviation occurs, the force will be transmitted to the adjusting guide mechanism on one side at the first time. The side guide wheel assembly in the adjusting guide mechanism will compress the upper and lower tracks in the track box to support and limit the steel pusher, and prevent the steel pusher from excessive deviation. At the same time, the disc spring assembly will produce a certain deformation and form a reaction force on the steel pusher. When the steel is pushed, the steel pusher returns to the center under the thrust of the compressed disc spring assembly, and automatic correction is achieved, thereby effectively preventing the drive mechanism and the push head from being worn and caused by accidents due to long-term operation in an offset state, greatly improving the safety of equipment operation, extending the service life of the equipment, reducing the frequency of maintenance, and improving production efficiency.

[0025] More specifically, the side guide wheel assembly 7 includes a side guide wheel 7-1, a guide wheel bracket 7-2, a fixing seat 7-3, and a fixing bolt 7-4. The side guide wheel 7-1 is arranged in the guide wheel bracket 7-2. The guide wheel bracket 7-2 and the fixing seat 7-3 are connected and fixed by fixing bolts 7-4. The bottom of the fixing seat 7-3 is welded to the steel pusher 1. In this embodiment, contact ends 7-1-1 are provided at both ends of the side guide wheel 7-1. The contact ends correspond to the upper and lower tracks in the track box. When an offset occurs, they directly contact the upper and lower tracks, limit the steel pusher during rolling, and prevent the steel pusher from excessively deviating to one side of the track box.

[0026] More specifically, the disc spring assembly 8 includes a support base 8-2, a disc spring 8-3, an outer protective shell 8-4, and an end cover 8-5. The two ends of the disc spring 8-3 are respectively abutted against the support base 8-2 and the end cover 8-5. The top of the outer protective shell 8-4 is connected to the end cover 8-5. The rear section of the outer protective shell 8-4 is movably connected to the support base 8-2. The disc spring assembly 8 also includes a fixed bottom plate 8-1 and a positioning column 8-6. The positioning column 8-6 passes through the end cover 8-5, the disc spring 8-3, the support base 8-2 and is movably connected to the fixed bottom plate 8-1. The end cover and the outer protective shell are welded as a whole. When the support base is subjected to force, it will compress the disc The spring enables the support base to be displaced along the positioning column to avoid hard obstruction to the steel cart. When the steel structure is pushed, the driving mechanism retreats, and the disc spring resets during the retreat process. Specifically, the disc spring on the compressed side releases and stretches after the compression ends, generating thrust to push the steel cart back to its original position, thereby realizing automatic correction and centering of the steel cart during the retreat stroke, avoiding the push rod and cylinder in the driving mechanism from continuing to operate when the whole is offset, thereby effectively reducing the overall wear of the equipment, extending the service life of the equipment, reducing the maintenance frequency and workload, improving production safety, and improving production efficiency.

[0027] To be more specific, the fixed bottom plate 8-1 is welded to the steel pusher 1. Welding the fixed bottom plate to the steel pusher enables the fixed bottom plate to stably push the disc spring to deform and recover after being stressed.

[0028] To be more specific, the end cover 8-5 is welded to the fixed seat 7-3. The welding of the end cover and the fixed seat ensures the connection stability of the side guide wheel assembly and the disc spring assembly. At the same time, since the end cover constrains the end of the positioning column, the limit column will not move after welding. The bottom of the fixed seat is also welded to the steel cart, thereby ensuring that the support base can move stably along the positioning column.

[0029] The working principle of the utility model is as follows: the upper track 10 and the lower track 11 are arranged inside the track box 9, the wheels 3 on both sides of the rear end of the steel pusher 1 are between the upper track 10 and the lower track 11, and the side guide wheel 7-1 at the front end is rollingly connected with the upper track 10 and the lower track 11 through the contact end 7-1-1, so as to generate radial force in this direction. When pushing steel, the oil cylinder 5 pushes the push rod 4 to drive the steel pusher 1 forward, and the push head 2 pushes the front end red blank to move. When the push head 2 is subjected to force, if there is an offset, the force generated by the offset acts on the disc spring assembly 8 on one side, and is further transmitted to The side guide wheel assembly 7, and the side guide wheel 7-1 compresses the upper track 10 and the lower track 11, and will not move further sideways under the constraints of the upper track 10 and the lower track 11, so that the side disc spring 8-3 produces a certain compression deformation. When the steel pushing is completed, the steel pushing car 1 retreats, and the force on the push head 2 disappears, and the steel pushing car 1 is no longer compressed. The disc spring 8-3 on the compressed side stretches to form a restoring thrust, realizing automatic correction, so that the push rod 4 of the driving part also returns to the original correct stroke trajectory when returning to its original position, and will not reset in the case of offset to cause excessive wear.

[0030] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
