Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel continuous casting equipment, and in particular to a lifting and pushing machine. Background Technology
[0002] In the billet discharge system of billet and round billet continuous casting equipment, the pusher is an important component. Its main function is to push the cut-to-length continuous casting billet from the discharge roller conveyor to the fixed cooling bed, achieving step cooling and collection of the billet. Traditional walking beam pushers can only achieve step-by-step pushing from the discharge roller conveyor to the fixed cooling bed when the elevations of the discharge roller conveyor and the fixed cooling bed are the same. When the elevation of the discharge roller conveyor is lower than that of the cooling bed, the continuous casting billet must be lifted first before step cooling and collection. Because traditional walking beam pushers cannot achieve this, an additional lifting device is required. This device lifts the pusher and the billet to adjust their height before pushing the billet. To ensure the pusher moves smoothly in the vertical direction, the existing lifting device requires a pair of lifting rods that move synchronously. Therefore, the existing lifting device has a complex structure, increasing equipment and operating costs. Therefore, a lifting and pushing machine is needed, which is set between the billet delivery roller table and the cooling bed in continuous casting. It can lift the billet to a high position and push it horizontally, combining multiple functions into one and sharing a single drive device. The total investment in the equipment is small and the manufacturing cost is low. Utility Model Content
[0003] To address the aforementioned issues, this utility model proposes a lifting and pushing machine, which is positioned between the continuous casting billet conveyor and the cooling bed. It can lift the billet to a certain height and push it horizontally, integrating multiple functions into one unit and sharing a single drive device. The total investment in the equipment is small, and the manufacturing cost is low.
[0004] This utility model is achieved through the following technical solution:
[0005] This utility model proposes a lifting and pushing steel machine, including: a transverse beam, a lifting beam, a lifting rail, a lifting cylinder, and a transverse cylinder. The lifting rail is installed on the ground, and the upper end face of the lifting rail is inclined. The side of the lifting beam is provided with a lifting guide wheel, and the lifting beam is slidably connected to the lifting rail through the lifting guide wheel. The upper part of the lifting beam is provided with a lower translation guide wheel, and the lower part of the transverse beam is connected to the lifting beam through the lower translation guide wheel. One end of the lifting cylinder and one end of the transverse cylinder are both connected to the ground through a mounting base. The other end of the lifting cylinder is connected to one end of the lifting beam through a first connecting rod and a second connecting rod, and the other end of the transverse cylinder is connected to one end of the transverse beam through a third connecting rod and a fourth connecting rod.
[0006] Furthermore, a billet support is provided on the upper part of the transverse beam, and the billet support moves between the billet roll and the fixed cooling bed via the transverse beam.
[0007] Furthermore, the billet support is provided with a pusher, the middle part of which is mounted on one side of the billet support via a pin, and a first limiting block is provided on one side of the lower part of the billet support.
[0008] Furthermore, both the lifting cylinder and the lateral cylinder are installed on the side close to the fixed cooling bed.
[0009] Furthermore, there are multiple lifting rails, and the installation height of the multiple lifting rails is the same. The lifting beam is connected to the lifting rails through multiple lifting guide wheels.
[0010] Furthermore, the transverse beam is also provided with an upper translation guide wheel, and the side of the transverse beam is provided with a protrusion, the outer periphery of the upper translation guide wheel is pressed tightly against the upper part of the protrusion.
[0011] Furthermore, the lifting guide wheel has a groove on its outer periphery, and the lifting guide wheel is connected to the lifting rail through the groove.
[0012] Furthermore, a second limiting block is provided on the lifting rail, the lower part of the second limiting block is clamped on the lifting rail, and the second limiting block is used to limit the lifting guide wheel.
[0013] The beneficial effects of this utility model are as follows: By setting a lifting beam and lifting rail at the lower part of the transverse beam, the lifting beam is moved on the lifting rail by the lifting cylinder, thereby realizing the height adjustment.

When there is a height difference between the billet roll and the fixed cooling bed, the billet can be lifted and pushed horizontally to realize the smooth billet discharge. This device integrates multiple functions into one, sharing a single drive device. The total investment of the equipment is small and the manufacturing cost is low. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0021] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of this utility model provides a lifting and pushing steel machine, including: a transverse beam 1, a lifting beam 2, a lifting rail 3, a lifting cylinder 6, and a transverse cylinder 7. The lifting rail 3 is installed on the ground, and the upper end face of the lifting rail 3 is inclined. The side of the lifting beam 2 is provided with a lifting guide wheel 4, and the lifting beam 2 is slidably connected to the lifting rail 3 through the lifting guide wheel 4. The upper part of the lifting beam 2 is provided with a lower translation guide wheel 5, and the lower part of the transverse beam 1 is connected to the lifting beam 2 through the lower translation guide wheel 5. One end of the lifting cylinder 6 and one end of the transverse cylinder 7 are both connected to the ground through a mounting base. The other end of the lifting cylinder 6 is connected to one end of the lifting beam 2 through a first connecting rod 8 and a second connecting rod 9. The other end of the transverse cylinder 7 is connected to one end of the transverse beam 1 through a third connecting rod 10 and a fourth connecting rod 11.
[0022] like Figure 2As shown, the operation flow of this lifting and pushing steel machine is ① waiting for billet → ② lifting → ③ pushing steel → ④ descending → ⑤ retracting → ⑥ waiting for billet, repeating the cycle. During the waiting period, both the lifting cylinder 6 and the transverse cylinder 7 are in the retracted state. At this time, the lifting guide wheels 4 on both sides of the lifting beam 2 are located at the lower part of the lifting rail 3. After the billet exits, it moves on the billet exit roller 13. When the billet moves to the upper part of the billet support 12, the lifting cylinder 6 begins to extend, driving the lifting beam 2 to move upward along the lifting rail 3 through the connecting rod, so that the height of the lifting beam 2 and the transverse beam 1 increases, causing the billet support 12 to lift the billet. After the lifting cylinder 6 extends to the predetermined position, the transverse cylinder... 7 begins to extend, thereby driving the transverse beam 1 and billet support 12 towards the fixed cooling bed 14 via the connecting rod, realizing the horizontal movement of the billet. After the billet has completely moved to the upper part of the fixed cooling bed 14, the transverse cylinder 7 stops extending, and then the lifting cylinder 6 retracts, causing the lifting beam 2 to move downward along the lifting rail 3, thereby reducing the height of the transverse beam 1 and billet support 12. After the billet support 12 descends, it supports the billet through the cooling bed. After the lifting cylinder 6 retracts, the transverse cylinder 7 retracts, causing the billet support 12 to move to the position of the billet waiting. The above cycle is repeated after the next billet moves to the billet support 12.
[0023] The lifting of the transverse beam 1 is achieved by the movement of the lifting beam 2 on the lifting rail 3. The height of the transverse beam 1 can be controlled by the lifting cylinder 6. The lifting mechanism has a simple structure and high reliability. The lifting beam 2 is raised by multiple lifting rails 3, and the height of the lifting beam 2 is highly uniform during the raising process. It integrates multiple functions into one unit and uses a single drive device, resulting in low total investment and low manufacturing cost.
[0024] The height difference between the billet discharge roller 13 and the fixed cooling bed 14 is generally 10cm to 20cm, while the lengths of the second connecting rod 9 and the fourth connecting rod 11 are 80cm to 100cm. Both ends of the second connecting rod 9 and the fourth connecting rod 11 are hinged, which can automatically adapt to the changes in the connecting rod angle caused by the height change during lifting. During lifting, the transverse beam 1 will move horizontally within a small range under the limit of the fourth connecting rod 11. The actual measured movement range is 2cm to 3cm, and its influence on the lifting and translation of the billet is basically negligible.
[0025] In a preferred embodiment, a billet support 12 is provided on the upper part of the transverse beam 1. The billet support 12 moves between the billet discharge roller 13 and the fixed cooling bed 14 via the transverse beam 1. The billet support 12 is mainly used to support the billet. When pushing the billet, it is supported by multiple billet supports 12. The billet support 12 moves in the space between the billet discharge rollers 13. Driven by the transverse beam 1, the billet is lifted and moved to the fixed cooling bed 14 along the axial direction of the billet discharge roller 13, thereby realizing the transfer of the billet.
[0026] Specifically, the billet support 12 is equipped with a pusher 15. The middle part of the pusher 15 is installed on one side of the billet support 12 via a pin. The lower part of the billet support 12 is equipped with a first limiting block 16. When the billet support 12 moves the billet to the upper part of the fixed cooling bed 14, the previous billet is placed in front of the fixed cooling bed 14. The pusher 15 can push the previous billet, thereby freeing up space for placing the new billet. When the upper part of the pusher 15 pushes the billet, the first limiting block 16 supports the lower part of the pusher 15, so that the pusher 15 obtains support force to push the billet. Since the upper part of the pusher 15 is higher than the support surface of the billet support 12, when the transverse beam 1 returns to the billet waiting position, the pusher 15 will move the billet. The lower part of the pusher 15 is only equipped with a first limiting block 16 on one side, so the pusher 15 can be moved by the billet, thus smoothly returning to the billet waiting position.
[0027] Preferably, the lifting cylinder 6 and the transverse cylinder 7 are both installed close to the fixed cooling bed 14, so that the second connecting rod 9 and the fourth connecting rod 11 mainly apply tension to counteract the reaction force of the transverse beam 1 when pushing the billet.
[0028] Preferably, there are multiple lifting rails 3, and the installation height of the multiple lifting rails 3 is the same. The lifting beam 2 is connected to the lifting rails 3 through multiple lifting guide wheels 4. Under the drive of the lifting cylinder 6, the lifting beam 2 causes the lifting guide wheels 4 to move synchronously on the lifting rails 3, so as to maintain the consistency of height during lifting.
[0029] In one specific embodiment, the transverse beam 1 is also provided with an upper translation guide wheel 17, and the side of the transverse beam 1 is provided with a protrusion. The outer periphery of the upper translation guide wheel 17 is pressed tightly against the upper part of the protrusion. The transverse beam 1 is limited by the upper translation guide wheel 17 and the lower translation guide wheel 5, so that the transverse beam 1 can only move along a straight line on the lifting beam 2, thus ensuring the stability of the transverse beam 1.
[0030] In a preferred embodiment, the lifting guide wheel 4 has a groove on its outer periphery. The lifting guide wheel 4 is connected to the lifting rail 3 through the groove. When subjected to lateral force, the lifting guide wheel 4 can be stably locked on the lifting rail 3 to improve stability and prevent the lifting guide wheel 4 from derailing from the lifting rail 3.
[0031] In a specific embodiment, such as Figure 3 As shown, a second limiting block 18 is provided on the lifting rail 3. The lower part of the second limiting block 18 is clamped on the lifting rail 3. The second limiting block 18 is used to limit the lifting guide wheel 4. The lower two sides of the second limiting block 18 are provided with clamping parts, and the second limiting block 18 is provided with locking bolts. After tightening the bolts, the distance between the clamping parts is reduced, so that the second limiting block 18 is clamped on the lifting rail 3, preventing the second limiting block 18 from moving on the lifting rail 3. The second limiting block 18 can limit the lifting guide wheel 4, thereby controlling the lifting height of the lifting beam 2, avoiding the lifting beam 2 from being raised too high, and also preventing the lifting guide wheel 4 from slipping out from the end of the lifting rail 3.
[0032] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
