[0030] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example

[0031] The utility model discloses an automatic stacking device for casting blanks, comprising: a stand 1, a support 2, a rocker 3, a connecting shaft 4, a rotating handle 5, a synchronization rod 6, a bearing seat 7, a hydraulic cylinder 8, a pin 9, a base 10, a guide column 11, a guide cylinder 12, a proximity switch sensing rod 13, a proximity switch group 14, a photoelectric detection device 15, a column 16, a buffer block 17, a proximity switch mounting plate 22, etc.

[0032] The tail end of the hydraulic cylinder 8 is welded and fixed to the base 10 through a pin 9, and the base 10 is fixed to the ground through anchor bolts. The rod end of the hydraulic cylinder 8 is hinged to the support 2 welded in the middle of the stand 1 through the pin 9, and the stand 1 is driven to move up and down synchronously through the extension and contraction of the hydraulic cylinder 8. In order to ensure the stability of the overall frame movement, four supports 2 are welded at the bottom of the stand 1 at the same time, and are respectively hinged to one end of the rocker 3 through a pin, and the other end of the rocker 3 is connected to one end of the handle 5 fixed on the connecting shaft 4. Bearing seats 7 are installed at both ends of the connecting shaft 4. 7 is fixed to the ground by bolts, and a synchronization rod 6 is arranged between the two rotating handles 5, so that the rocker 3, the connecting shaft 4, the rotating handle 5, and the synchronization rod 6 can move synchronously with the hydraulic cylinder 8, thereby ensuring the balance of the up and down movement of the platform 1; in order to control the hydraulic cylinder 8 to realize automatic start and stop, the proximity switch group 14 for controlling the hydraulic cylinder 8 to stop the movement is fixed to the bearing seat 7 through the proximity switch mounting plate 22, and the proximity switch mounting plate 22 is fixed to the bearing seat 7 by bolts, and the proximity switch group 14 includes proximity switch A 1401, proximity switch B 1402, proximity switch C 1403, and proximity switch C 1404. 1403 and proximity switch D1404, the proximity switch sensing rod 13 matched with the proximity switch group 14 is welded on the connecting shaft 4. When the connecting shaft 4 rotates, the proximity switch sensing rod 13 rotates with the connecting shaft 4 to reach the sensing range of the single proximity switch. After the proximity switch senses, the hydraulic cylinder 8 can be controlled to stop by the controller; by adjusting the position of each proximity switch, the upper surface of the uppermost ingot can be flush with the roller surface each time it stops; in order to prevent the platform 1 from deflecting or tilting when moving up and down, guides are welded on both sides of the bottom of the platform 1 Column 11, the linear bearing matched with the guide column 11 is fixed on the ground; in order to prevent the hydraulic cylinder 8 and other devices from being damaged during the falling process of the platform 1, two groups of buffer blocks 17 are installed on the ground directly below the left and right sides of the platform 1; photoelectric detection devices 15 fixed to the ground through columns 16 are respectively arranged on the ground on both sides of the platform 1, and the two groups of photoelectric detection devices 15 are in the same horizontal plane with the upper surface of the platform 1 (the upper surface at the initial position, that is, the roller surface) to detect whether there is a continuous casting billet on the platform 1, so as to guide the hydraulic cylinder 8 to produce corresponding actions;

[0033] The working process of the utility model is as follows:

[0034] The utility model of the automatic stacking device for casting billets is mainly used at the end of the continuous casting billet conveying area. When the continuous casting billet stacking device is in a non-working state, the hydraulic cylinder 8 is in the maximum stroke. At this time, the upper surface of the stand 1 and the upper surface of the conveying roller 18 are in the same plane. When the continuous casting billet 19 moves to the end with the conveying roller 18, the continuous casting billet 19 is intercepted by the baffle 20 and stops moving forward. The pusher 21 (the existing technology, which pushes the billet out of the conveying roller) pushes the continuous casting billet 19 from the surface of the conveying roller 18 to the stand 1 of the continuous casting billet stacking device. When the photoelectric When the detection device 15 detects that the continuous casting billet 19 stays on the platform 1 for more than a certain period of time, it sends a signal to the main control system. The main control system will respond with a contraction signal to the hydraulic cylinder 8. The contraction of the hydraulic cylinder 8 drives the platform 1 and the guide column 11 to move downward. The guide column 11 moves downward along the matching linear bearing to prevent the platform 1 from deviating from the up and down movement. The contraction of the hydraulic cylinder 8 drives the rocker 3, the connecting shaft 4, the turning handle 5, and the synchronous rod frame 6 to move synchronously. The proximity switch sensing rod 13 welded on the connecting shaft 4 rotates with the rotation of the connecting shaft 4. When the proximity switch sensing rod 1 3 rotates to the second proximity switch 1402 of the proximity switch group 14, the main control system controls the hydraulic cylinder to stop moving. At this time, the upper surface of the continuous casting billet on the stand 1 is in the same plane with the upper surface of the conveyor roller 18 again. When the second continuous casting billet is stacked, the proximity switch sensing rod 13 rotates to the sensing range of the proximity switch 1403, and the hydraulic cylinder also stops moving. When the third continuous casting billet is stacked, the proximity switch sensing rod 13 rotates to the sensing range of the proximity switch 1404, and the hydraulic cylinder 8 stops contracting again and is at the minimum stroke; when the fourth continuous casting billet is stacked on the continuous casting billet After the stacking platform is installed, the photoelectric detection devices 15 on both sides detect that the continuous casting billet 19 has stopped, and the hydraulic cylinder 8 can no longer retract. At this time, the main control system controls the hydraulic cylinder 8 to extend upward until the proximity switch sensing rod 13 rotates with the connecting shaft 4 to the sensing range of the proximity switch 1401. The main control system controls the hydraulic cylinder to stop moving. At this time, the hydraulic cylinder 8 is in the maximum stroke again, the upper surface of the platform 1 and the upper surface of the conveyor roller 18 are in the same plane, and the continuous casting billet stacking platform device is in the initial state. Then, the four stacked continuous casting billets are lifted to the inventory area at one time by a crane. On the other hand, in order to prevent the platform 1 from causing damage to the hydraulic cylinder 8 and other devices during the falling process, two groups of buffer blocks 17 are installed on the ground directly below the left and right sides of the platform 1. When the platform 1 falls back to a certain distance, it contacts the buffer blocks 17, and an upward reaction force is generated after contact to prevent the platform 1 from moving downward again.

[0035] The specific usage and function of this embodiment are as follows:

[0036] The utility model is installed at the end of the continuous casting billet 9 conveying roller 18. When the continuous casting billet 19 moves to the end with the conveying roller 18, the continuous casting billet 19 is intercepted by the baffle 20 and stops moving forward. The pusher 21 pushes the continuous casting billet 19 from the surface of the conveying roller 18 to the stand 1 of the continuous casting billet stacking device. The main control system controls the extension and retraction state of the hydraulic cylinder 8 according to the signals detected by the photoelectric detection devices 15 on both sides and the position relationship between the proximity switch sensing rod 13 and the proximity switch group 14. The extension and retraction of the hydraulic cylinder 8 drives the whole device to move synchronously, so that the whole device moves upward or downward; the online continuous casting billet 19 is taken off the line and neatly stacked at a certain position, and the counting and positioning functions are realized at the same time. When the continuous casting billet 19 reaches a certain number, it is lifted to the storage area by a crane at one time, which not only saves a lot of continuous casting billet 19 off the line and transportation time, but also improves the efficiency of stacking the continuous casting billet 19. At the same time, the device is also provided with a buffer block 17, which can prevent the hydraulic cylinder 8 and other devices from being damaged during the fall of the stand 1.
