Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment, and in particular to a continuous scrap steel material receiving and transporting device. Background Technology

[0002] In continuous casting production lines, risers and sprues of castings need to be removed at the line's exit. These removed risers and sprues are then recycled as scrap steel for recasting. Previously, scrap steel was transported using forklifts and trolleys, which was inefficient. To improve efficiency and automate production, railcars are now commonly used for automated recycling. The railcar consists of a track between the production line exit and the furnace. Scrap steel recycling trolleys run on this track. A vibrating conveyor at the production line exit transports the scrap steel out, and the recycling trolleys automatically transport it to the furnace for unloading. This process repeats. However, due to the long distance between the production line exit and the furnace, the round trip time for the scrap steel recycling trolleys is also long. During this time, the vibrating conveyor must stop, leading to occasional scrap steel accumulation that cannot be cleared in a timely manner, and resulting in low operating efficiency. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a continuous scrap steel material receiving and transporting device that can realize continuous material receiving and transporting, thereby improving efficiency.

[0004] The technical implementation scheme of this utility model is as follows: a continuous scrap steel material receiving and transporting device includes two conveyors, one of which has a vertical frame fixedly connected to one side, a hydraulic cylinder is provided at the lower part of the vertical frame, a connecting plate is vertically fixedly connected to the telescopic end of the hydraulic cylinder, and two pallets are fixedly connected to the connecting plate. The conveyor transports a first car and a second car for carrying scrap steel material. Two mounting frames are connected between the two pallets. The two mounting frames are symmetrically arranged, and each mounting frame is equipped with a cylinder. A push plate is fixedly connected to the telescopic end of each cylinder.

[0005] Furthermore, the vertical frame consists of two vertically installed columns and two horizontally installed cross plates, with reinforcing ribs at both ends of the two cross plates.

[0006] Furthermore, the tray has an L-shaped structure, with the vertical portion of the L-shaped tray fixedly connected to the connecting plate, and the vertical portion is provided with reinforcing ribs.

[0007] Furthermore, when the telescopic end of the hydraulic cylinder is not extended, the two pallets are at their lowest point, and the two pallets are lower than the rotating rollers of the conveyor.

[0008] Furthermore, both cylinders are controlled by the same controller, and the two cylinders operate synchronously.

[0009] Furthermore, the push plate is equipped with multiple wheels to increase the number of contact points without hindering the movement of the first and second carriages.

[0010] This utility model has the following advantages: By using a hydraulic cylinder and a pallet, the receiving times of the first and second carriages are staggered. When the first carriage is receiving material, the second carriage can either feed material or wait, achieving continuous material receiving. There is no need to wait for the waste recycling trolley to unload the material before sending the carriage back, thus improving the efficiency of transportation. Furthermore, by using two synchronized cylinders, when the first or second carriage is waiting at the pallet, the extension and retraction ends of the cylinders extend to straighten the carriage, preventing the carriage from shifting and causing it to detach from the conveyor or affect the loading of the carriage during subsequent transfers.

[0015] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-3 As shown, a continuous scrap steel transport device includes two conveyors 1. Each conveyor 1 consists of a frame, drive rollers and a transmission assembly mounted on the frame, and a motor. The motor drives the drive rollers to rotate via the transmission assembly. Conveyors 1 transport a first car 61 and a second car 62 for carrying scrap steel. When the motor drives the drive rollers to rotate via the transmission assembly, it moves the first car 61 and the second car 62. The two conveyors 1 are connected, allowing either the first car 61 or the second car 62 to be transported from one conveyor 1 to the other.

[0017] One of the conveyors 1 has a vertical frame 2 fixedly connected to one side. The vertical frame 2 consists of two vertically installed columns and two horizontally installed cross plates. Reinforcing ribs are provided at both ends of the two cross plates to ensure the strength of the vertical frame 2. A hydraulic cylinder 3 is located at the lower part of the vertical frame 2. A connecting plate 4 is vertically fixed to the telescopic end of the hydraulic cylinder 3, and two support plates 5 are fixed to the connecting plate 4. The support plates 5 have an L-shaped structure, with their vertical portions fixed to the connecting plate 4 and reinforced with ribs to enhance the strength of the horizontal portion and prevent deformation. The extension and retraction of the hydraulic cylinder 3 drives the lifting and lowering of the two support plates 5. When the telescopic end of the hydraulic cylinder 3 extends and lifts the first carriage 61 through the connecting plate 4 and the support plate 5, the second carriage 62 can pass under the first carriage 61; when the telescopic end of the hydraulic cylinder 3 extends and lifts the second carriage 62 through the connecting plate 4 and the support plate 5, the first carriage 61 can pass under the second carriage 62. Therefore, the first carriage 61 and the second carriage 62 can pass alternately, realizing alternating material receiving.

[0018] Two mounting brackets 7 are connected between the two pallets 5. The two mounting brackets 7 are symmetrically arranged, and each mounting bracket 7 is equipped with a cylinder 8. The two cylinders 8 are controlled by the same controller and operate synchronously. Push plates 9 are fixed to the telescopic ends of the two cylinders 8. When the telescopic ends of the two cylinders 8 extend simultaneously, they drive the two push plates 9 to move towards the center. As the push plates 9 move, they push the passing first carriage 61 or second carriage 62, straightening it. The push plates 9 are equipped with multiple rotating wheels 10 to increase the contact points without hindering the movement of the first carriage 61 and the second carriage 62.

[0019] When the telescopic end of the hydraulic cylinder 3 is not extended, the two pallets 5 are at their lowest point, lower than the rotating rollers of the conveyor 1. This structure prevents the pallets 5 from affecting the normal passage of the first carriage 61 or the second carriage 62.

[0020] In operation, the second conveyor 1 transports the second carriage 62 to the receiving point. The telescopic end of the hydraulic cylinder 3 extends, lifting the first carriage 61 via the connecting plate 4 and the support plate 5. The bottom of the support plate 5 is higher than the second carriage 62. When the second carriage 62 is full of waste material, the first and second conveyors 1, through motor-driven transmission rollers, move the second carriage 62 onto the waste recycling trolley. Simultaneously, the telescopic end of the hydraulic cylinder 3 retracts, placing the first carriage 61 on the first conveyor 1. The first and second conveyors 1 then move the first carriage 61 to the receiving point. At this time, the second carriage 62... 2. After unloading the material, return to the platform and move above the pallet 5. The telescopic ends of the two cylinders 8 extend simultaneously, driving the two push plates 9 to move towards the center. As the push plates 9 move, they push the second carriage 62, straightening it. Then, the telescopic ends of the cylinders 8 retract, and the telescopic ends of the hydraulic cylinder 3 extend again, lifting the second carriage 62 through the pallet 5. After the first carriage 61 is filled with material and moves away from under the pallet 5, the second carriage 62 is lowered and the material is received again. Repeating this operation can achieve continuous material receiving without waiting for the waste recycling trolley to unload the material and then return the carriage, thus improving the efficiency of material receiving.

[0021] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
