The calculation module calculates the power to be output by the linear power mechanism 110 according to the judgment result, and transmits the calculation result to the instruction module. The command module transmits the calculation result to the linear power mechanism 110.
When the detecting device 150 detects that the distance between the end of the support 140 and 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 support arm 120 to swing relative to the synchronizing shaft 130, so that the distance between the end of the support 140 and the axis of the synchronizing shaft 130 reaches the preset distance; when the controller 160 controls the linear power mechanism 110 to drive the support arm 120 to swing relative to the synchronization shaft 130, so that the distance between the end of the support 140 and the axis of the synchronization shaft 130 reaches the preset distance, the controller 160 controls the power mechanism to stop working, thereby realizing automatic control of the lifting device 100 to accurately lift to the preset height.
In this embodiment, the controller 160 is communicatively coupled to the linear motor mechanism 110 and the detection device 150. In other embodiments of the present application, the controller 160 may be connected to the linear motor mechanism 110 and the detecting device 150 by other connection methods such as a circuit connection.
In this embodiment, the controller 160 may be a single-chip microcomputer. It should be noted that, in other embodiments of the present application, the controller 160 may not be limited to a single-chip microcomputer.
The lifting device 100 provided in this embodiment has at least the following advantages:
one end of the support arm 120 is connected to the output end 111 of the linear power mechanism 110, and the other end of the support arm 120 is connected to one end of the synchronizing shaft 130. The extending direction of the support arm 120 forms an angle with the first direction 101. The carrier 140 is connected to an end of the synchronization shaft 130 remote from the support arm 120. The cooperation of the detection device 150 and the controller 160 enables the automatic control of the end of the carrier 140 at a specified height. If, during the lifting process, it is assumed that the end of the supporting member 140 does not reach the preset height due to wear or the like, the detecting device 150 immediately detects that the distance between the end of the supporting member 140 and the axis of the synchronizing shaft 130 does not reach the preset distance, and then 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 supporting member 140 can swing, and the supporting member 140 swings to enable the distance between the end of the supporting member 140 and the axis of the synchronizing shaft 130 to reach the preset distance, thereby realizing automatic lifting control of the lifting device 100 to the preset height.
Example 2
Fig. 3 shows a schematic structural view of a lifting device 200 for a steel-tapping machine according to an embodiment of the present application, and fig. 4 shows a sectional view in A-A direction in fig. 3. Referring to fig. 3 and 4, the present embodiment provides a steel-tapping machine lifting device 200, and as an example, the steel-tapping machine lifting device 200 may be used for a medium plate heating furnace apparatus.
The lifting device 200 of the tapping machine provided by the embodiment comprises a plurality of lifting devices 100 and a plurality of discharging rods 210, wherein the lifting devices are arranged side by side; the number of the discharging rods 210 is the same as the number of the holders 140 in the elevating device 100. Referring to embodiment 1, the structure and connection relationship of the lifting device 100 will not be described in detail.
Each of the discharging rods 210 of the lifting device 200 of the steel-tapping machine is abutted with one of the supporting members 140, the supporting members 140 are used for supporting the discharging rods 210, and each of the discharging rods 210 is used for supporting and conveying a steel billet together. The direction of conveyance of the billet is defined as the second direction 201.
Referring again to fig. 4, in the present embodiment, the steel-tapping machine lifting device 200 includes 4 lifting devices 100 arranged side by side, and the 4 lifting devices 100 are simultaneously used to support one steel billet, so that stable support of the steel billet can be achieved. During the billet conveying process, if the supporting member 140 or the discharging rod 210 of one of the lifting devices 100 in the steel-tapping machine lifting device 200 is worn, the discharging rod 210 cannot be abutted against the billet, and the remaining 3 lifting devices 100 normally support the billet. The lifting device 100 with the abrasion of the supporting piece 140 can realize stable supporting of the steel billet by the contact of the discharging rod 210 and the steel billet through the matching of the components, thereby avoiding the phenomenon that the tail of the steel billet contacts the bearing seat of the steel-tapping roller way to cause the steel billet to be pulled askew in the tapping process due to the insufficient height of some supporting pieces 140. It should be noted that, in other embodiments of the present application, the number of the lifting devices 100 included in the steel-discharging machine lifting device 200 may be 2, 3, or more.
The detecting device 150 is used for detecting the distance between the position of the discharging rod 210, which is used for being abutted against the billet, and the axis of the synchronizing shaft 130 and converting the distance into a detection signal.
The controller 160 is used for controlling the linear power mechanism 110 so that each discharging rod 210 can abut against the billet. When the detecting device 150 detects that the distance between the portion of the discharging rod 210, which is used for being abutted against the billet, and 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 between the portion of the discharging rod 210, which is used for being abutted against the billet, and the axis of the synchronizing shaft 130 reaches the preset distance. The preset distance is a distance between the billet and the axis of the synchronizing shaft 130.
The lifting device 200 for the steel-tapping machine provided by the embodiment has the advantage of the lifting device 100. During the billet conveying process, if the supporting member 140 or the discharging rod 210 of one of the lifting devices 100 in the tapping machine lifting device 200 does not reach the preset height due to abrasion and other reasons, the detecting device 150 of the lifting device 100 can instantly detect the distance between the position of the discharging rod 210, which is used for being abutted against the billet, and the axis of the synchronous shaft 130 and send out a detection signal, the controller 160 receives the detection signal and immediately controls the linear power mechanism 110 to output the force along the first direction 101 to drive the supporting arm 120 to swing relative to the synchronous shaft 130, so that the supporting member 140 can swing, the supporting member 140 swings, the distance end between the position of the position, which is used for being abutted against the billet, of the discharging rod 210 in the tapping machine lifting device 200 and the axis of the synchronous shaft 130 reaches the preset distance, and each discharging rod 210 can be always kept at the preset height, so that the tapping machine lifting device 200 can stably support the billet and convey the billet along the second direction 201, and thus the phenomenon that the bearing seat of the height of the discharging rod 210 is not enough to cause the rolling way of the billet to warp in the process is avoided.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
