Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet processing technology, specifically to a lifting receiving trolley for a silicon steel sheet cross-cutting production line. Background Technology

[0002] In the cross-cutting production of silicon steel sheets, the receiving trolley is a key piece of equipment for the efficient transfer of the sheared silicon steel sheets (mostly coils or stacked sheets). Its degree of automation and transfer efficiency directly affect the continuous operation of the production line.

[0003] Currently, in the material receiving process of silicon steel sheet shearing lines, most receiving carts adopt a two-layer fixed receiving method, with the upper material column being manually lifted and requiring the use of an overhead crane. The outputs of the upper and lower material columns cannot be automatically connected, which further extends the operation time. For small shearing lines, the same configuration of receiving carts results in high procurement costs and high plant configuration costs. Existing receiving carts cannot meet the requirements for a simple and low-cost material receiving method. Utility Model Content

[0004] In view of the problems existing in the lifting receiving car of the existing silicon steel sheet cross-cutting production line, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a lifting receiving trolley for a silicon steel sheet cross-cutting production line, which solves the problem that the existing receiving trolley adopts a fixed receiving form with upper and lower layers, the upper layer of material column is manually lifted and requires the use of a crane for lifting, and the output of the upper and lower layers of material column cannot be automatically connected, thus further extending the operation time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A lifting receiving trolley for a silicon steel sheet cross-cutting production line has a C-shaped overall structure, including an upper receiving frame, two side columns, a lower receiving platform, a linear guide rail, an upper receiving frame connecting seat, a middle connecting beam, and an upper receiving frame lifting mechanism. The two side columns are respectively connected to both ends of the middle connecting beam. The linear guide rail is fixedly connected to the upper surface of the lower receiving platform along the height direction of the two side columns. The upper receiving frame is slidably connected to the linear guide rail through the upper receiving frame connecting seat. The upper receiving frame lifting mechanism includes a reducer, a first sprocket, and a first chain. The first sprocket and the first chain are symmetrically distributed on both sides of the middle connecting beam. The reducer drives the first chain through the first sprocket. One end of the first chain is connected to the upper receiving frame to drive it to move up and down along the linear guide rail. The lower receiving platform includes a trolley body, a power roller assembly, and a traveling mechanism. The power roller assembly is used to drive the material column to move longitudinally, and the traveling mechanism is used to drive the trolley body to move laterally.

[0007] Preferably, the power roller assembly includes rollers evenly distributed inside the vehicle body, a roller reducer, a second sprocket, and a second chain; the rollers are mounted on the upright plates on both sides of the vehicle body, with one end positioned and the other end locked with a nut; the roller reducer is installed at the center inside the vehicle body and drives the rollers to rotate through the second sprocket and the second chain.

[0008] Preferably, the walking mechanism includes wheels, a connecting shaft, gears, and a walking motor; the wheels and gears are mounted on the bottom of the vehicle body, and the walking motor drives the connecting shaft to rotate through gear transmission, thereby driving the wheels to move the entire device laterally.

[0009] Preferably, the lifting stroke of the upper receiving frame is not less than the vertical distance between the lower receiving platform and the initial position of the upper layer.

[0010] Preferably, there are two linear guide rails, symmetrically distributed on the inner sides of the two columns.

[0011] Preferably, the first sprocket, the first chain, and the second sprocket and the second chain in the power roller assembly are all made of wear-resistant alloy steel and their surfaces are hardened.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses a reducer to drive a sprocket and chain to raise and lower the upper receiving frame along a linear guide rail. It can be precisely lowered to be flush with the lower receiving platform, realizing the automatic transfer of material columns from the upper to the lower layer. This replaces the traditional manual lifting and crane coordination mode, reduces the transfer time of a single batch of material columns, improves efficiency, and avoids scratches on silicon steel sheets caused by manual operation. It is especially suitable for continuous operation in large-scale cross-cutting production lines.

[0013] 2. This utility model achieves longitudinal conveying of material columns through a power roller assembly, and with the gear transmission of the walking mechanism, the receiving car can flexibly switch between different workstations on the production line, expanding the coverage area compared to a fixed receiving car.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a lifting receiving trolley for a silicon steel sheet cross-cutting production line.

[0019] This utility model provides, for example Figure 1-4 The diagram shows a lifting receiving trolley for a silicon steel sheet cross-cutting production line. The overall structure is C-shaped, including an upper receiving frame 1, two side columns 2, a lower receiving platform 3, linear guide rails 4, an upper receiving frame connecting seat 5, a central connecting beam 6, and an upper receiving frame lifting mechanism. The two side columns 2 are respectively connected to both ends of the central connecting beam 6. The linear guide rails 4 are fixedly connected to the upper surface of the lower receiving platform 3 along the height direction of the two side columns 2. The upper receiving frame 1 is slidably connected to the linear guide rails 4 via the upper receiving frame connecting seat 5. The upper receiving frame lifting mechanism includes a deceleration mechanism. The reducer 7, first sprocket 8, and first chain 9 are symmetrically distributed on both sides of the middle connecting beam 6. The reducer 7 drives the first chain 9 through the first sprocket 8. One end of the first chain 9 is connected to the upper receiving frame 1 to drive it to move up and down along the linear guide rail 4. The lower receiving platform 3 includes a car body 10, a power roller assembly, and a traveling mechanism. The power roller assembly is used to drive the material column to move longitudinally, and the traveling mechanism is used to drive the car body 10 to move laterally. The lifting stroke of the upper receiving frame 1 is not less than the vertical distance between the lower receiving platform 3 and the initial position of the upper layer.

[0020] After the reducer 7 starts, it drives the first chain 9 to rotate through the first sprocket 8 at the output end. Since one end of the first chain 9 is connected to the upper receiving frame 1, and the upper receiving frame 1 is slidably connected to the linear guide rail 4 through the connecting seat 5, the traction of the first chain 9 causes the upper receiving frame 1 to rise and fall stably along the linear guide rail 4 on the inner side of the two side columns 2. The lifting stroke is not less than the vertical distance between the lower receiving platform 3 and the initial position of the upper layer, ensuring that the upper receiving frame 1 can be lowered to be flush with the lower receiving platform 3, realizing the smooth transfer of the material column from the upper layer to the lower layer without manual lifting, thus improving the receiving efficiency.

[0021] like Figure 1-4 As shown, the power roller assembly includes rollers 11, roller reducers 12, second sprockets 13 and second chains 14, which are evenly distributed inside the vehicle body 10. The rollers 11 are mounted on the upright plates on both sides of the vehicle body 10, with one end positioned and the other end locked with a nut. The roller reducers 12 are installed at the center inside the vehicle body 10 and drive the rollers 11 to rotate through the second sprockets 13 and the second chains 14.

[0022] The roller reducer 12 starts, driving multiple rollers 11 inside the vehicle body 10 to rotate synchronously via the second sprocket 13 and the second chain 14. Silicon steel sheet columns are placed on the rollers 11 and move longitudinally with the rotation of the rollers, facilitating the transport of the columns from the receiving position to storage or the next process position. One end of the roller 11 is positioned, and the other end is locked with a nut to ensure stability during rotation.

[0023] like Figure 1-3 As shown, the walking mechanism includes wheels 15, connecting shafts 16, gears 17 and walking motors 18; wheels 15 and gears 17 are mounted on the bottom of the vehicle body 10, and the walking motor 18 drives the connecting shafts 16 to rotate through the gears 17, thereby driving the wheels 15 to move the entire equipment laterally.

[0024] The walking motor 18 drives the connecting shaft 16 to rotate through the gear 17. The connecting shaft 16 drives the wheels 15 at the bottom of the vehicle body 10 to rotate, so that the whole equipment moves laterally, realizing the flexible switching of the receiving vehicle at different positions on the production line and adapting to the material receiving needs of multiple workstations.

[0025] like Figure 1-2 As shown, there are two linear guide rails 4, symmetrically distributed on the inner sides of the two columns 2.

[0026] The two side columns 2 are symmetrically distributed, and the middle connecting beam 6 enhances the rigidity of the frame, ensuring the overall structural stability of the upper receiving frame 1 when it is raised and lowered. Two symmetrically distributed linear guide rails 4 provide precise guidance for the upper receiving frame 1, avoiding deviation or shaking during the raising and lowering process, and ensuring the accuracy of the receiving position.

[0027] like Figure 1-4As shown, the first sprocket 8, the first chain 9, and the second sprocket 13 and the second chain 14 in the power roller assembly are all made of wear-resistant alloy steel and their surfaces are hardened.

[0028] The first sprocket 8, the first chain 9, and the second sprocket 13 and the second chain 14 in the power roller assembly are all made of wear-resistant alloy steel and have undergone surface quenching treatment, which significantly improves the wear resistance and fatigue strength of the components, making them suitable for high-frequency material receiving and transfer operations on the production line and extending the service life of the equipment.

[0029] In summary, when using this device, silicon steel sheets are stacked on the upper and lower receiving platforms by a sorting machine. When both receiving platforms are full of a column of material, the material cart moves laterally to the external transfer vehicle position for unloading. First, the lower column of material is transferred to the external transfer vehicle via an automatic roller conveyor. Then, the upper receiving platform descends to the lower working position and the upper column of material is transferred to the external transfer vehicle via the conveyor. After unloading, the upper receiving platform rises to the upper working position. This discharge method does not require the use of a crane, making transportation convenient. The upper and lower layers are output at the same height, making docking simple and reducing manufacturing costs.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
