Description

Technical Field

[0001] The utility model relates to the field of rolling production lines, in particular to a billet conveying and pushing device for a rolling production line. Background Technique

[0002] A billet conveying and pushing device is a mechanical device specifically used in the iron and steel production line to push billets from one position to another. In the iron and steel production process, billets need to go through multiple processes such as heating, rolling, and cooling, and the billet conveying and pushing device plays a connecting and transitional role between these processes;

[0003] Chinese Patent with publication number CN215158920U discloses a pushing and conveying device, including legs, a platform, a conveying device, a pushing block, and a cylinder. A number of legs are vertically arranged, and the legs are arranged in a rectangular shape. The platform is arranged in a rectangular shape and is set on each leg. The side of the conveying device is parallel to one side of the platform, and the conveying device is close to the platform. The pushing block is slidably arranged on the platform. The long side of the pushing block is parallel to the side of the conveying device, and the pushing block is close to the conveying device. The pushing block is used to push the materials conveyed by the conveying device. The cylinder is arranged on the platform and is fixedly connected to the pushing block. The cylinder is used to push the pushing block, and this device has the effect of changing the conveying direction of goods.

[0004] During the transportation and pushing of the above-mentioned pushing and conveying device, during the pushing process of the pushing block, it will continuously adhere to the conveyor belt for transmission. During the process of the pushing block pushing and retracting, it will affect the subsequent continuous transmission of rolled steel. In order to avoid the collision of rolled steel, it is necessary to reduce the transmission speed of rolled steel, which affects the transportation efficiency of the rolling production line and the subsequent processing efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a billet conveying and pushing device for a rolling production line. When the pushing block is driven by the first hydraulic telescopic rod to push the billets at the upper end of the second conveyor belt, the reserved cavity at the lower end of the first connecting frame on one side of the pushing block will avoid affecting the subsequent billet transmission of the second conveyor belt. After the pushing block retracts, the drive of the motor can drive the pushing block to tilt. After the pushing block tilts, the first hydraulic telescopic rod can contract and complete the reset, avoiding affecting the movement of the pushing block by adjusting the transmission efficiency of the second conveyor belt, and solving the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A billet conveying and pushing device for a steel rolling production line, comprising a pushing block. At the upper end of one side of the pushing block, a first hydraulic telescopic rod is provided. At the lower end of the pushing block, a base for support is provided. Horizontally at the lower end of the pushing block, a first connecting frame for support is provided. At the lower end outside the first connecting frame, a recessed reserved cavity is provided. At the other side of the lower end of the base, a connecting strip is provided. The connecting strip is welded and fixed to the base. At one end of the connecting strip, a motor for output is provided. The output shaft of the motor is welded and fixed to the connecting strip through a connecting shaft.

[0007] Preferably, a groove is provided inside the pushing block. Inside the groove of the pushing block, a second connecting frame is inclinedly provided. Inside the second connecting frame, rollers are horizontally and evenly distributed. And both ends of the rollers are rotatably connected to both ends inside the second connecting frame respectively.

[0008] Preferably, at the lower end of the first hydraulic telescopic rod, a second hydraulic telescopic rod is provided. Between the telescopic position of the second hydraulic telescopic rod and the second connecting frame, a transmission frame for transmission is provided.

[0009] Preferably, on one side of the first connecting frame, an extension strip is provided. And the extension strip is welded and fixed to one side of the pushing block.

[0010] Preferably, on both sides of the reserved cavity, sliding grooves for sliding are provided. Inside the sliding grooves outside, sliding strips are provided. And the outside of the sliding strips is slidably connected to the inside of the sliding grooves through sliding chucks.

[0011] Preferably, the sliding strips are welded and fixed to the base.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. When the first hydraulic telescopic rod extends and retracts and the pushing block pushes the billet at the upper end of the second conveyor belt to move to the first conveyor belt, the sliding strip slides inside the sliding groove at the lower end inside the pushing block to limit the pushing block. During the process of restricting the movement of the pushing block by the sliding strip, the first connecting frame will be driven to slide horizontally together. The horizontal sliding of the first connecting frame can move the recessed reserved cavity at the lower end outside the first connecting frame to the upper end of the second conveyor belt. The billets subsequently conveyed at the upper end of the second conveyor belt can directly slide from the recessed reserved cavity, avoiding the influence of the pushing block pushed by the first hydraulic telescopic rod on the billets subsequently conveyed at the upper end of the second conveyor belt. When the pushing block needs to contract after being pushed, the output of the motor can enable the base and the pushing block to rotate around the connecting shaft as the center. After rotating and unfolding, the first hydraulic telescopic rod can contract to drive the pushing block to reset. The horizontal movement and pushing of the pushing block will not affect the billets subsequently conveyed, and there is no need to adjust the conveying speed of the second conveyor belt for the horizontal movement of the pushing block.

[0014] 2. When the first hydraulic telescopic rod of the present utility model expands and contracts and the billet transported at the upper end of the second conveyor belt is lifted by the push block and moves, the billet longer than the push block can directly contact the inclined position of the outer wall of the push block, and can directly push the billet to move to the upper end of the rolling table board. While the billet shorter than the push block will directly sink into the inside of the push block, causing the billet to move towards the rolling table board together with the push block. After the first hydraulic telescopic rod expands and contracts to the set maximum length, the expansion and contraction of the second hydraulic telescopic rod can actively drive the roller to push the billet sunken inside the push block, enabling the billet to be actively discharged to the upper end of the rolling table board, adapting to billets of different lengths, avoiding the situation where smaller billets cannot be pushed due to inertia and directly move to the upper end of the rolling table board, assisting in the pushing and ensuring that billets of all sizes can be moved to the upper end of the rolling table board by the extrusion of the roller, achieving smooth billet pushing and improving the stability during billet pushing and feeding.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] In order to solve the problem that in the existing pusher conveying device during transportation and pushing, during the pushing process of the push block, it will continuously adhere to the conveyor belt for transmission, and during the process of the push block pushing and retracting, it will affect the subsequent continuous transmission of rolled steel. In order to avoid the collision of the rolled steel, it is necessary to reduce the transmission speed of the rolled steel, which affects the transportation efficiency of the rolled steel production line and the subsequent processing efficiency. The following technical solutions are provided in this embodiment:

[0023] A billet conveying and pushing device for a rolled steel production line, including a push block 8. At the upper end of one side of the push block 8, a first hydraulic telescopic rod 7 is provided. At the lower end of the push block 8, there is a base 1 for support. As Figure 1 shown, the outside of the first hydraulic telescopic rod 7 is fixedly connected to the upper end of the base 1 by bolts. By the expansion and contraction of the first hydraulic telescopic rod 7, the push block 8 can be pushed to move, so that the push block 8 pushes the steel billet transported at the upper end of the second conveyor belt 5;

[0024] In this embodiment, a first connecting frame 9 for support is horizontally arranged at the lower end of the push block 8. At the lower end of the outside of the first connecting frame 9, there is a recessed reserved cavity 10. As Figure 2 、 Figure 3 and Figure 5 shown, an extension bar 12 is arranged on one side of the first connecting frame 9, and the extension bar 12 is fixedly welded to one side of the push block 8. Sliding grooves 11 for sliding are arranged on both sides of the reserved cavity 10. Inside the outside of the sliding grooves 11, there are sliding bars 16, and the outside of the sliding bars 16 is connected to the inside of the sliding grooves 11 by sliding card slots. The sliding bars 16 are fixedly welded to the base 1. During the process of the first hydraulic telescopic rod 7 expanding and contracting and pushing the push block 8 to move horizontally, the push block 8 will cause the sliding bars 16 to slide in the sliding grooves 11. By using the sliding bars 16 at the upper end of the base 1 as support, the stability of the movement of the push block 8 can be ensured;

[0025] In this embodiment, on the other side of the lower end of the base 1, there is a connecting bar 13, and the connecting bar 13 is fixedly welded to the base 1. As Figure 4 shown, at one end of the connecting bar 13, there is a motor 14 for output. The output shaft of the motor 14 is fixedly welded to the connecting bar 13 by a connecting shaft 15. By the output of the motor 14, the base 1 can be driven to rotate by the connecting bar 13. While the base 1 rotates, it can drive the push block 8 to rotate around the connecting shaft 15 and tilt upwards, which is convenient for the subsequent storage of the push block 8 and avoids the retraction of the push block 8 from affecting the subsequent steel billet transmission of the second conveyor belt 5;

[0026] In this embodiment, there is a groove inside the push block 8. Inside the groove of the push block 8, a second connecting frame 19 is inclined. Inside the second connecting frame 19, rollers 20 are horizontally and evenly distributed, and both ends of the rollers 20 are rotatably connected to both ends inside the second connecting frame 19. As Figure 1 and Figure 3As shown, the billet sunken inside the pushing block 8 can be driven by the second connecting frame 19 and then pushed out of the pushing block 8 by the roller 20. The roller 20 can accommodate billets of different sizes, and through the pushing of the roller 20, the billet sunken inside the pushing block 8 can be pushed out, improving the efficiency of billet pushing and preventing the billet from staying inside the pushing block 8;

[0027] In this embodiment, a second hydraulic telescopic rod 17 is arranged at the lower end of the first hydraulic telescopic rod 7. A transmission frame 18 for transmission is arranged between the telescopic position of the second hydraulic telescopic rod 17 and the second connecting frame 19, as Figure 1 and Figure 3 shown. The rear end of the second hydraulic telescopic rod 17 is fixedly connected to the outer wall of the pushing block 8 through bolts. Through the telescoping of the second hydraulic telescopic rod 17 and the transmission of the transmission frame 18, the roller 20 can move horizontally and extend out of the pushing block 8;

[0028] In this embodiment, a tray 2 is arranged on the other side outside the base 1, and the outside of the tray 2 is connected to the card slot on one side outside the base 1. After the output of the motor 14, the base 1 can drive the pushing block 8 at the upper end to be directly placed on the tray 2. The tray 2 can support the pushing block 8, as Figure 1 and Figure 4 shown. A second conveyor belt 5 is arranged on the other side of the tray 2, and the second conveyor belt 5 is used to convey billets;

[0029] In this embodiment, a rolling table plate 3 is arranged on the other side outside the second conveyor belt 5, and a first conveyor belt 4 is arranged on the other side outside the rolling table plate 3, as Figure 1 shown. The billet pushed by the pushing block 8 will move from the second conveyor belt 5 to the upper end of the rolling table plate 3, and the billet moving to the upper end of the rolling table plate 3 will fall to the upper end of the first conveyor belt 4 due to the weight of the billet itself;

[0030] In this embodiment, supports 6 for support are arranged at the lower ends of the first conveyor belt 4, the rolling table plate 3, the second conveyor belt 5, the tray 2 and the base 1, as Figure 1 shown. Through the supports 6, the first conveyor belt 4, the rolling table plate 3, the second conveyor belt 5, the tray 2 and the base 1 at the upper end can be supported and lifted, which is convenient for the transmission and pushing of billet materials.

[0031] Working principle: When the practical device pushes and conveys the steel billets conveyed by the second conveyor belt 5, when the steel billets conveyed by the second conveyor belt 5 move to one side of the push block 8, the first hydraulic telescopic rod 7 is started. Under the support of the first hydraulic telescopic rod 7, the push block 8 moves towards the second conveyor belt 5. The outer shell of the push block 8 contacts the steel billets on the upper end of the second conveyor belt 5, directly causing the steel billets to move towards the rolling table 3. Smaller steel billets will sink into the interior of the push block 8. After the first hydraulic telescopic rod 7 extends to a set length, the telescopic movement of the second hydraulic telescopic rod 17 can push the transmission frame 18, so that the transmission frame 18 drives the roller 20 through the second connecting frame 19 to squeeze the smaller steel billets inside the push block 8, enabling the steel billets to fall onto the upper end of the rolling table 3 and finally slide onto the upper end of the first conveyor belt 4. After the first hydraulic telescopic rod 7 extends and stops contracting, the motor 14 is started. The output shaft of the motor 14 can drive the connecting bar 13 and the upper base 1 to rotate around the connecting shaft 15 as the center. The base 1 can drive the push block 8 to rotate clockwise. After the push block 8 rotates clockwise and tilts away from the second conveyor belt 5, the first hydraulic telescopic rod 7 contracts and the push block 8 returns to its original position. After the push block 8 returns to its original position, the motor 14 drives and makes the base 1 contact the upper end of the tray 2.
