The lifting device 100 with the abraded supporting piece 140 can realize stable supporting of the steel billet by abutting the discharging rod 210 and the steel billet through matching of all components, so that the phenomenon that the steel billet is pulled askew due to the fact that the tail of the steel billet touches a steel tapping roller bearing seat in the steel tapping process due to the fact that the height of some supporting pieces 140 is not enough is avoided. It should be noted that in other embodiments of the present application, the number of the lifting devices 100 included in the steel tapping machine lifting device 200 may be 2, 3, or more.
The detection device 150 is used for detecting the distance from the part of the discharging rod 210, which is used for being abutted with the billet, to the axis of the synchronizing shaft 130 and converting the distance into a detection signal.
The controller 160 is configured to control the linear actuator 110 to enable each discharging rod 210 to abut the billet. When the detection device 150 detects that the distance from the position of the discharging rod 210 for abutting against the steel billet to the axis of the synchronizing shaft 130 does not reach the preset distance, the controller 160 controls the linear power mechanism 110 to drive the supporting arm 120 to swing relative to the synchronizing shaft 130, so that the distance from the position of the discharging rod 210 for abutting against the steel billet to the axis of the synchronizing shaft 130 reaches the preset distance. The preset distance is the distance between the billet and the axis of the synchronizing shaft 130.
The tapping machine elevating apparatus 200 provided in the present embodiment has the advantages of the elevating apparatus 100. In the process of conveying steel billets, if the top end of the discharge rod 210 of one lifting device 100 of the steel tapping machine lifting devices 200 does not reach the preset height due to abrasion and the like, the detection device 150 of the lifting device 100 can instantly detect the distance from the part of the discharge rod 210 for abutting against the steel billets to the axis of the synchronizing shaft 130 and send a detection signal, the controller 160 receives the detection signal and immediately controls the linear power mechanism 110 to output a force along the first direction 101 to drive the supporting arm 120 to swing relative to the synchronizing shaft 130 so as to enable the support 140 to swing, the support 140 swings to enable the distance end, from the part of the discharge rod 210 for abutting against the steel billets, of the position of the discharge rod 210 for abutting against the axis of the synchronizing shaft 130 to reach the preset distance, the top end of each discharge rod 210 in the steel tapping machine lifting devices 200 is automatically controlled to be always maintained at the preset height, and each discharge rod 210 can abut against the steel billets, the steel discharging machine lifting device 200 can stably support the steel billet and convey the steel billet along the second direction 201, so that the phenomenon that the steel billet is pulled askew due to the fact that the tail of the steel billet touches a steel discharging roller bearing seat in the steel discharging process due to the fact that the height of a certain discharging rod 210 is insufficient is avoided.
