Description

Technical Field

[0001] This utility model belongs to the technical field of steel rolling equipment, and specifically relates to a double-line rolling steel separation device. Background Technology

[0002] A steel-separating device is installed between the roughing mill and the intermediate mill to separately transport the rolled pieces from the roughing mill to the two intermediate mill lines. The existing steel-separating device has three parallel roller conveyors. The middle roller conveyor connects to the exit of the roughing mill. The rolled pieces stop on the middle roller conveyor after being rolled, and hydraulically driven levers located below the roller conveyors lift and flip the pieces onto the corresponding roller conveyor. This roller conveyor then transports the pieces to the corresponding intermediate mill. The existing steel-separating device has the following disadvantages: 1) High failure rate: Multiple hydraulic cylinders drive the steel-separating levers, requiring synchronized start-up, flipping, and stopping. After long-term operation, coaxiality and synchronization are difficult to guarantee, leading to incomplete flipping and steel accumulation. 2) Rapid wear rate: Each rolled piece needs to be flipped by the levers, causing rapid wear of components such as the levers, shafts, and hydraulic cylinders. Frequent replacement is necessary, and uneven wear between new and old parts makes adjustment difficult and prone to failure. 3) The rolled piece carries a certain amount of kinetic energy when it flips from the middle roller table to the side roller tables, which impacts both the roller tables and the rolled piece, affecting the service life of the roller tables and the quality of the rolled piece. 4) A hydraulic station is required to achieve the steel separation operation, which consumes a relatively high amount of energy. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a double-line rolling steel separation device that improves steel separation efficiency and facilitates maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A double-line rolling steel separating device includes a box body and roller conveyors. Three rows of roller conveyors are arranged side by side on the steel discharge side of the box body. A set of tracks is laterally connected to the top of the box body on the steel inlet side. A suspension device that can move on the tracks is provided on the tracks. A crossbeam is connected to the top of the box body on the steel discharge side. A hinge rod is movably connected to the crossbeam. Two deflector plates are provided inside the box body. The two deflector plates are driven by cylinders symmetrically arranged outside the box body. The end of the deflector plate on the steel inlet side is connected to the suspension device, and the end of the deflector plate on the steel discharge side is connected to the hinge rod.

[0006] The box body includes a bottom plate and a trough, the trough including a width-reducing section and a width-equalizing section arranged along the running direction of the rolled piece.

[0007] A connecting rod is movably connected to the piston rod of the cylinder, and the outer end of the connecting rod is fixedly connected to the middle part of the lever plate.

[0008] The bottom of the cylinder is connected to a cylinder bracket, and the cylinder bracket is fixedly connected to the housing.

[0009] The suspension device includes a hanging block, rollers connected to the axle heads on both sides of the hanging block, the rollers being rotatably connected to the track, the middle part of the hanging block moving through the suspension rod, the bottom of the suspension rod being fixedly connected to the lever plate, and the top of the suspension rod being threadedly connected to the locking nut.

[0010] The hinge rod includes a shaft that moves through the crossbeam, is fixedly connected to the lever plate, and has a positioning nut threaded to the top of the shaft.

[0011] Compared with existing technologies, the beneficial effects of this utility model are:

[0012] This invention employs two symmetrical sets of cylinders to drive the deflector plates. During steel separation, the two sets of cylinders work together to guide the rolled piece into its respective roller table. When the downstream intermediate rolling mill cannot accept new rolled pieces, the two sets of cylinders can retract simultaneously, opening the two deflector plates and guiding the rolled piece into the intermediate roller table. This prevents steel accumulation and adapts to various unexpected situations on the rolling line. This invention has a simple structure, improves steel separation efficiency, and is easy to maintain and repair. It requires no hydraulic station, reducing energy consumption.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figures 1-4 A double-line rolling steel-separating device includes a box body 1 and roller conveyors 2. Three parallel roller conveyors 2 are arranged on the steel-exit side of the box body 1. A set of rails 4 are laterally connected to the top of the box body 1 on the steel-in side. A suspension device 5 that can move on the rails 4 is provided on the rails 4. A crossbeam 3 is connected to the top of the box body 1 on the steel-exit side. A hinge rod 8 is movably connected to the crossbeam 3. Two deflector plates 7 are provided inside the box body 1. The two deflector plates 7 are driven by cylinders 9 that are symmetrically arranged outside the box body 1. The end of the deflector plate 7 on the steel-in side is connected to the suspension device 5, and the end of the deflector plate 7 on the steel-exit side is connected to the hinge rod 8.

[0021] The box body 1 includes a bottom plate 11 and a trough 12. The trough 12 includes a narrowing section 13 and a constant width section 14 arranged along the running direction of the rolled piece. The width of the trough 12 on the steel inlet side is greater than the width on the steel outlet side, which allows the opening of the deflector plate on the steel inlet side of the trough 12 to be larger than that on the steel outlet side, ensuring that the rolled piece can enter smoothly.

[0022] A connecting rod 6 is movably connected to the piston rod of the cylinder 9, and the outer end of the connecting rod 6 is fixedly connected to the middle part of the lever plate 7.

[0023] The bottom of the cylinder 9 is connected to the cylinder bracket 10, and the cylinder bracket 10 is fixedly connected to the housing 1.

[0024] The suspension device 5 includes a hanging block 51, rollers 52 are connected to the shaft heads on both sides of the hanging block 51, the rollers 52 are rotatably connected to the track 4, the middle part of the hanging block 51 moves through the hanging rod 53, the bottom of the hanging rod 53 is fixedly connected to the lever plate 7, and the top of the hanging rod 53 is threadedly connected to the locking nut 54.

[0025] The hinge rod 8 includes a shaft 81, which moves through the crossbeam 3 and is fixedly connected to the lever plate 7. The top of the shaft 81 is threadedly connected to a positioning nut 82.

[0026] The steel inlet side of the box body is provided with guide grooves 40.

[0027] Work process:

[0028] Rolled pieces a20 and b30 enter the steel inlet side of the box 1 through the guide groove 40. The cylinders 9 on both sides push and pull the two guide plates 7, so that the suspension devices 5 at the ends of the two guide plates 7 on the steel inlet side are in contact. The suspension devices 5 slide on the track 4 under the action of the rollers 52. Rolled pieces a20 and b30 are guided into the outer two roller tracks of the three parallel roller tracks 2 under the guidance of the guide plates 7. This alternating process realizes double-line production.

[0029] When the downstream rolling mill needs to be stopped, and the rolling mill has already entered the guide groove 40, the cylinders 9 on both sides retract simultaneously, causing the suspension devices 5 at the steel-in-the-steel side ends of the two guide plates 7 to separate. The rolled piece enters the middle roller table of the three parallel roller tables 2 between the two guide plates 7, and steel piling will not occur.
