Description

Technical Field

[0001] The present application relates to the technical field of steelmaking continuous casting equipment, and in particular to a storage device for flexible dummy rods of large-section casting billets. Background Art

[0002] For the continuous casting machines of square and round billets with larger cross-sections, chain-type flexible dummy rods are mostly used for dummy rods and billet pulling. A dummy rod storage device is usually provided to realize the convenient insertion and withdrawal of the dummy rods. Before pouring, the dummy rod storage device is used to lift the dummy rod from the storage position to the roller table so that the dummy rod can be put into work; after the dummy rod is removed, the dummy rod sent back along the roller table is withdrawn from the roller table to the storage position on the side of the roller table and stored waiting for the next casting. The existing flexible dummy rod storage devices mostly adopt a parallel four-bar structure, which lifts the dummy rod by the swing of the mechanism, and the driving hydraulic cylinder that provides power is located at the bottom of the roller table, so that the swing height difference of the connecting rod is large, which makes it easy for the device for moving the dummy rod to be unable to move smoothly to the working position of the roller table. Utility Model Content

[0003] In view of this, the present application proposes a storage device for flexible dummy rods of large-section ingots, which can smoothly move the dummy rods from a storage position to a working position of a roller table.

[0004] According to one aspect of the present application, there is provided a storage device for flexible dummy rods of large-section casting billets, comprising: a synchronous shaft, a driving hydraulic cylinder, a storage bracket, a driving connecting rod and a driven connecting rod;

[0005] The driving hydraulic cylinder is suitable for being arranged outside the roller table;

[0006] The synchronization shaft is arranged between the driving hydraulic cylinder and the roller table;

[0007] The two ends of the driven connecting rod are rotatably connected to the bottom of the roller conveyor and the storage bracket respectively;

[0008] The two ends of the driving connecting rod are rotationally connected to the storage bracket and the hydraulic rod of the driving hydraulic cylinder respectively, and the middle part of the driving connecting rod is connected to the synchronization shaft. The driving hydraulic cylinder drives the driving connecting rod to drive the storage bracket to move from the storage position to the working position of the roller table.

[0009] In a possible implementation, a rotating portion is provided at the bottom of the roller conveyor;

[0010] The driven connecting rod is rotatably connected to the roller conveyor through the rotating part;

[0012] In a possible implementation, the driven connecting rod is arranged in parallel with the driving connecting rod;

[0013] The rotation angle of the driven connecting rod is equal to the rotation angle of the driving connecting rod.

[0014] In a possible implementation, the rotation angle of the driving connecting rod is in the range of 100 degrees to 110 degrees.

[0015] In a possible implementation, one end of the driving connecting rod is a first driving end, and the other end is a first driven end, the driving end is drivingly connected to the hydraulic rod of the driving hydraulic cylinder, driving the driving connecting rod to rotate around the synchronization shaft, and the first driven end is movably connected to a rotating side of the storage bracket away from the roller conveyor;

[0016] One end of the driven connecting rod is a second driving end, and the other end is a second driven end. The second driving end is rotationally connected to a side of the storage bracket adjacent to the roller conveyor, and the second driven end is rotationally connected to the bottom of the roller conveyor.

[0019] In a possible implementation manner, an outer cover of the driving hydraulic cylinder is provided with a protective cover.

[0022] In a possible implementation, the height difference distance of the displacement of the first driven end of the driving connecting rod is 1 / 5 of the rotation diameter of the driving connecting rod.

[0023] The beneficial effects of the storage device for the flexible dummy rods for large-section castings of the embodiment of the present application: Compared with the original storage of dummy rods, the storage device for the dummy rods of the present application optimizes the position of each hinge point and the external dimensions of the connecting rod, greatly optimizes the running track of the equipment, and realizes the low-level translation of the dummy rods from the storage position to the working position, that is, the movement distance of the dummy rods is larger and the movement height is smaller. Not only that, the dummy rods can be translated from the storage position to the working position along a smoother trajectory, and the equipment heights of the storage position and the working position are not much different, thereby providing a larger operating space above and on the side of the roller, facilitating maintenance and lifting of castings, etc. Due to the low swing height, the overall center of gravity of the equipment during the swing process is reduced, making the equipment run more smoothly.

[0033] See also Figure 1 and Figure 2 The storage device for the flexible ingot guide rod of the large-section casting ingot of the embodiment of the present application includes: a synchronous shaft 300, a driving hydraulic cylinder 100, a storage bracket 300, a driving connecting rod 200 and a driven connecting rod 400. The driving hydraulic cylinder 100 is suitable for being arranged on the outside of the roller table 500. The synchronous shaft 300 is arranged between the driving hydraulic cylinder 100 and the roller table 500. The two ends of the driven connecting rod 400 are rotatably connected to the bottom of the roller table 500 and the storage bracket 300, respectively. The two ends of the driving connecting rod 200 are rotatably connected to the storage bracket 300 and the hydraulic rod of the driving hydraulic cylinder 100, respectively, and the middle part of the driving connecting rod 200 is connected to the synchronous shaft 300. The driving hydraulic cylinder 100 drives the driving connecting rod 200 to drive the storage bracket 300 to move from the storage position 610 to the working position 620 of the roller table 500.

[0034] In this embodiment, compared with the original storage of the dummy rod 600, the storage device of the dummy rod 600 of the present application optimizes the running track of the equipment by optimizing the positions of each hinge point and the outer dimensions of the connecting rod, and realizes the low-level translation of the dummy rod 600 from the storage position 610 to the working position 620, that is, the moving distance of the dummy rod 600 is larger and the moving height is smaller. In addition, the dummy rod 600 can be translated from the storage position to the working position 620 along a smoother trajectory, and the equipment height of the storage position and the working position 620 is not much different, thereby providing a larger operating space above and on the side of the roller table 500, facilitating maintenance and lifting of the ingot, etc., and due to the low swing height, the overall center of gravity of the equipment during the swing process is reduced, making the equipment run more smoothly.

[0035] In this embodiment, the driving hydraulic cylinder 100 is arranged on the outside of the roller table 500. On the one hand, the driving hydraulic cylinder 100 is kept as far away from the heat source as possible, which can effectively reduce the impact of heat radiation on the driving hydraulic cylinder 100. On the other hand, it also avoids the damage to the driving hydraulic cylinder 100 caused by high-temperature iron oxide scale falling off the ingot. In addition, because there is no other equipment blocking the top of the driving hydraulic cylinder 100, it is more convenient to install and maintain the equipment.

[0036] In this embodiment, the lateral space between adjacent rollers 500 is large, thereby providing sufficient placement space for the storage device of the dummy rod 600, so that the driving hydraulic cylinder 100 can be arranged outside the roller 500, so that when overcoming the maximum resistance, the hydraulic cylinder is in a state of no rod cavity output, and the output of the driving hydraulic cylinder 100 is increased compared to the solution arranged below the roller 500, so that a smaller specification of the driving hydraulic cylinder 100 can be used under the same load. In addition, the main force-bearing components such as the storage bracket 300, the driven connecting rod 400, the driving connecting rod 200 are welded with thick steel plates and thick-walled seamless steel pipes, and have sufficient bearing capacity.

[0037] In a specific embodiment, a rotating portion 510 is provided at the bottom of the roller 500, and the driven connecting rod 400 is rotatably connected to the roller 500 through the rotating portion 510, and the rotating portion 510 is located on the track near the driving hydraulic cylinder 100, so that it can be used as a fulcrum for rotation, so that the driven rod rotates around the rotating portion 510. In addition, the rotating portion 510 and the synchronization shaft 300 are located in the same horizontal plane, and the length of the driven connecting rod 400 is half the length of the driving connecting rod 200. The driven connecting rod 400 is arranged in parallel with the driving connecting rod 200, so that the frequency and angle of the driven connecting rod 400 can be consistent with the driving connecting rod 200, so that the storage bracket 300 can move more smoothly.

[0038] In this embodiment, the rotation angle of the driving connecting rod is in the range of 100 degrees to 110 degrees.

[0039] In a specific embodiment, one end of the driving connecting rod 200 is a first driving end, and the other end is a first driven end. The driving end is drivingly connected to the hydraulic rod of the driving hydraulic cylinder 100, driving the driving connecting rod 200 to rotate around the synchronization axis 300, and the first driven end is rotatably connected to a rotation side of the storage bracket 300 away from the roller 500. One end of the driven connecting rod 400 is a second driving end, and the other end is a second driven end. The second driving end is rotationally connected to a side of the storage bracket 300 adjacent to the roller 500, and the second driven end is rotationally connected to the bottom of the roller 500.

[0040] In a specific embodiment, the moving track of the storage bracket 300 is arc-shaped, and the rotation angle of the storage bracket 300 is the same as the rotation angle of the driving connecting rod, both of which are within the range of 100 degrees to 110 degrees, and the storage position 610 and the working position 620 of the storage bracket 300 are in the same horizontal plane, so the movement of the dummy rod 600 on the storage bracket 300 is more stable. Compared with the traditional storage device for the dummy rod 600, the storage position 610 and the moving position of the dummy rod 600 of the present application are in the same horizontal plane, so there will be no large drop in the silver ingot rod during the movement, which prevents the silver ingot rod from falling from the storage bracket, and the height difference distance of the storage bracket 300 is 1 / 5 of the rotation diameter of the driving connecting rod 200.

[0041] In a specific embodiment, the outer cover of the driving hydraulic cylinder 100 is provided with a protective cover 110, which can effectively shield and protect the exposed cylinder head and hydraulic rod when the driving hydraulic cylinder 100 is extended.

[0042] In a specific embodiment, the first driven end of the driving connecting rod 200 is bent from the storage position 610 of the storage bracket to the working position 620 of the storage bracket, and the bending angle is in the range of 120 degrees to 140 degrees. The second driving end of the second driven connecting rod 400 is bent from the working position 620 of the storage bracket to the storage position 610 of the storage bracket, and the bending angle is in the range of 130 degrees to 150 degrees. The storage device for the guide rod 600 of the present application optimizes the outer dimensions of the driving connecting rod 200 and the driven connecting rod 400, so that the running trajectory of the storage bracket 300 is greatly optimized, thereby realizing the low-level translation of the guide rod 600, that is, the moving distance of the guide rod 600 is larger and the moving height is smaller.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
