Description

Technical Field

[0001] This utility model relates to the field of steel coil turning technology, specifically a turning and positioning device for steel coil production. Background Technology

[0002] Steel coils are products made by rolling steel into a coil shape after processing such as cold rolling or hot rolling. After the steel coil is formed, it needs to be flipped so that it stands vertically on the transport rack for easy transportation. However, since a steel coil is very heavy, flipping it is quite difficult, and it is impossible to flip it manually. Therefore, steel coil flipping machines are widely used in the market. They can stably flip the steel coil 90°, turning it from a horizontal position to an vertical position.

[0003] Chinese Patent Publication No. CN221875586U describes a turning device for producing rolled steel. Through the cooperation of a dual-axis motor, lead screw, fixed bracket, sliding block, threaded hole, limiting groove and clamping plate, the device can clamp and limit the movement of the steel coil, preventing the steel coil from shifting to the side and causing accidental safety hazards.

[0004] While the aforementioned patent can clamp and limit the movement of steel coils, if the steel coil is not clamped by two clamping plates when placed horizontally, it will roll. According to the aforementioned patent... Figure 3 As can be seen, the clamping plates are relatively large in order to clamp steel coils of different diameters. Therefore, during the clamping process, because the steel coil is very heavy, the two clamping plates need a very large clamping force to lift and clamp the steel coil. As a result, the two clamping plates may deform the steel coil during clamping, making it difficult to place the steel coil on the roller of the processing equipment when using it later. Utility Model Content

[0005] The purpose of this invention is to provide a flipping and positioning device for steel coil production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flipping and positioning device for steel coil production includes a base frame and an L-shaped flipping table. Arc-shaped plates are fixedly connected to both sides of the outer side of the flipping table. A lifting mechanism for lifting and raising the steel coil is provided on one side of the flipping table, a positioning mechanism for positioning and fixing the steel coil is provided on one side of the flipping table, and a pushing mechanism is provided on the other side of the flipping table.

[0008] The lifting mechanism includes a C-shaped frame fixedly connected to the bottom surface of the tilting table. Four rectangularly distributed hydraulic cylinders are fixedly connected to the inner bottom surface of the C-shaped frame. The output ends of the four hydraulic cylinders pass through the tilting table and are fixedly connected to a bracket. The bracket has a V-shaped structure. Rectangular grooves are equally spaced on two opposite sides inside the bracket. A circular roller is rotatably connected between the two ends inside the rectangular groove.

[0009] Furthermore, the pushing mechanism includes a fixed plate fixedly connected between two arc-shaped plates, and four hydraulic cylinders II distributed in a ring at equal angles are fixedly connected to the top surface of the fixed plate. The output ends of the four hydraulic cylinders II all pass through the tilting table and are fixedly connected to a push plate.

[0010] Furthermore, a groove is provided on the other side of the flipping table, and the push plate is embedded inside the groove.

[0011] Furthermore, the top surface of the push plate is provided with multiple rectangular grooves at equal intervals, and a circular roller is rotatably connected between the two ends of the rectangular groove.

[0012] Furthermore, the bottom frame has guide rails fixedly connected to its two opposite sides, and the side of the arc plate has a slide rail that slides within the guide rail at the corresponding position. The bottom frame has a rotating shaft rotatably connected to its two opposite sides, and a gear is fixedly connected to the outer wall of the rotating shaft. The outer wall of the arc plate has an arc-shaped rack that meshes with the gear at the corresponding position. A dual-axis motor is fixedly connected to the inner bottom surface of the bottom frame, and the two output ends of the dual-axis motor are fixedly connected to the rotating shaft at the corresponding position.

[0013] Furthermore, two symmetrical sliding holes are provided through one side of the flipping table, and the positioning mechanism includes two V-shaped clamps that slide on the side of the flipping table. The bottom end of the clamps is fixedly connected to a connecting plate that slides in the corresponding sliding hole, and a limit block is fixedly connected to the outside of the connecting plate.

[0014] Furthermore, the bottom end of the connecting plate is fixedly connected to a movable plate, the side of the arc-shaped plate is rotatably connected to a screw that is screwed through and engaged with the movable plate at the corresponding position, and the side of the tilting table is fixedly connected to a dual-axis motor II, the two output ends of the dual-axis motor II are respectively fixedly connected to the screws at the corresponding positions.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using the bracket and four hydraulic cylinders in combination, the steel coil can be lifted and raised. Then, the positioning mechanism can be used to position the steel coil, which can avoid the positioning mechanism from applying too much force to the steel coil and causing deformation. Moreover, the pushing mechanism makes it easy for workers to pass the sling through the steel coil and lift the steel coil away with the hoisting equipment.

[0017] 2. Driven by the dual-axis motor, the two clamping plates can clamp and position the steel coil, making the steel coil more stable when flipping and preventing it from slipping off the flipping table or collapsing due to inertia during the flipping process. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 7 In this embodiment of the present invention, a flipping and positioning device for steel coil production includes a base frame 1 and an L-shaped flipping table 2. The flipping table 2 can be flipped back and forth at 90 degrees within the base frame 1. Arc-shaped plates are fixedly connected to both sides of the outer side of the flipping table 2. A lifting mechanism 3 for lifting and raising the steel coil is provided on one side of the flipping table 2, and a positioning mechanism 4 for positioning and fixing the steel coil is provided on another side of the flipping table 2. A pushing mechanism 5 is provided on the other side of the flipping table 2. The lifting mechanism 3 includes a C-shaped frame 31 fixedly connected to the bottom surface of the flipping table 2. Four rectangularly distributed hydraulic cylinders 32 are fixedly connected to the inner bottom surface of the C-shaped frame 31. The output ends of the four hydraulic cylinders 32 pass through the flipping table 2 and are fixedly connected to a bracket 33. The bracket 33 has a V-shaped structure. Rectangular grooves are equally spaced on the two opposite sides of the bracket 33. A circular roller 34 is rotatably connected between the two ends of the rectangular grooves.

[0028] Specifically, firstly, based on the initial placement of the steel coil, the side of the tilting table 2 is selected for placement. If the initial state of the steel coil is vertical, it can be placed on the pushing mechanism 5 using a forklift or lifting equipment. Then, the positioning mechanism 4 positions and fixes the steel coil. Simultaneously, the four hydraulic cylinders 32 drive the bracket 33 to move until the multiple rollers 34 contact the steel coil. By rotating the tilting table 2 90 degrees, the steel coil is flipped from vertical to horizontal. Since the steel coil is in contact with the multiple rollers 34, after the steel coil is flipped to horizontal, the bracket 33 can support the steel coil through the multiple rollers 34, preventing the steel coil from falling off the positioning mechanism. 4. The steel coil is prevented from slipping due to its own weight and deformation under the clamping and limiting effect of the positioning mechanism 4, thanks to the cooperation of bracket 33 and four hydraulic cylinders 32. (Because the steel coil is relatively heavy, relying solely on the positioning mechanism 4 to clamp and fix it may cause it to fall. Furthermore, after clamping, if the steel coil is not supported by bracket 33, its sides may be restricted and deformed under its own weight.) If it is necessary to use lifting equipment to transport the steel coil to a warehouse (lifting equipment typically uses slings to pass through the steel coil and then lift it), a pushing mechanism can be used to facilitate the passage of the slings through the horizontal steel coil. 5. Push the horizontal steel coil forward a certain distance, then separate the pushing mechanism 5 from the steel coil. At this time, the worker can pass the lifting strap through the inside of the steel coil. If the steel coil is placed horizontally, it can be placed on multiple rollers 34 on the bracket 33 using a forklift or lifting equipment. Then, the steel coil can be moved upward by the drive of four hydraulic cylinders 32, and clamped and positioned by the drive of the positioning mechanism 4. (Since the bracket 33 can support the steel coil through four hydraulic cylinders 32, then the steel coil only needs to be in contact with the positioning mechanism 4 to avoid the steel coil shifting during the flipping process.) The presence and cooperation of the positioning mechanism 4 can prevent the steel coil from being deformed due to excessive clamping force. Then, the steel coil is driven by the pushing mechanism 5 to contact one end of the pushing mechanism 5. The steel coil is turned from horizontal to vertical by the reverse flipping of the flipping table 2. The device can lift and raise the steel coil by the cooperation of the bracket 33 and four hydraulic cylinders 32. The positioning mechanism 4 is used to position the steel coil, which can prevent the positioning mechanism 4 from applying excessive force to the steel coil and causing deformation. Moreover, the pushing mechanism 5 makes it easy for workers to pass the sling through the steel coil and lift the steel coil away with the lifting equipment.

[0029] Example 1

[0030] like Figure 7As shown, in this embodiment, the pushing mechanism 5 includes a fixed plate 51 fixedly connected between two arc-shaped plates. Four hydraulic cylinders 52 arranged in a ring at equal angles are fixedly connected to the top surface of the fixed plate 51. The output ends of the four hydraulic cylinders 52 all pass through the tilting table 2 and are fixedly connected to a push plate 53. A groove 22 is provided on the other side of the tilting table 2. The push plate 53 is embedded in the groove 22. A plurality of rectangular slots are provided at equal intervals on the top surface of the push plate 53. A circular roller 54 is rotatably connected between the two ends of the rectangular slot.

[0031] In this embodiment, the push plate 53 can be moved by the drive of four hydraulic cylinders 52. The moving push plate 53 can push the steel coil forward. Then, the push plate 53 is driven back to its original position by the reverse drive of the four hydraulic cylinders 52, which can separate the steel coil from the push plate 53. This makes it easier for workers to pass the sling through the inside of the steel coil. Then, the steel coil can be lifted away by the hoisting equipment using the sling. The friction on the steel coil can be reduced by the use of the first round roller 34 and the second round roller 54.

[0032] Example 2

[0033] like Figure 2 and Figure 4 As shown, in this embodiment, guide rails 11 are fixedly connected to the two opposite sides of the interior of the bottom frame 1. A slide rail 23 is fixedly connected to the side of the arc plate and slidably connected to the guide rail 11 at the corresponding position. A rotating shaft is rotatably connected to the two opposite sides of the interior of the bottom frame 1. A gear 12 is fixedly connected to the outer wall of the rotating shaft. An arc-shaped rack 24 that meshes with the gear 12 at the corresponding position is fixedly connected to the outer wall of the arc plate. A dual-axis motor 13 is fixedly connected to the inner bottom surface of the bottom frame 1. The two output ends of the dual-axis motor 13 are fixedly connected to the rotating shaft at the corresponding position.

[0034] In this embodiment, the dual-axis motor 13 drives the two gears 12 to rotate the corresponding arc racks 24. The two rotating arc racks 24 can rotate the flipping table 2, thereby flipping the steel coil from vertical to horizontal or from horizontal to vertical.

[0035] Example 3

[0036] like Figure 6As shown, in this embodiment, two symmetrical sliding holes 21 are opened through one side of the flipping table 2. The positioning mechanism 4 includes two V-shaped clamping plates 41 that slide on the side of the flipping table 2. The bottom end of the clamping plate 41 is fixedly connected to a connecting plate 42 that slides in the corresponding sliding hole 21. A limit block 46 is fixedly connected to the outside of the connecting plate 42. A moving plate 43 is fixedly connected to the bottom end of the connecting plate 42. A screw 44 that is rotatably connected to the side of the arc plate and screws through and screws into the moving plate 43 at the corresponding position is connected to the side of the flipping table 2. A dual-axis motor 45 is fixedly connected to the side of the flipping table 2. The two output ends of the dual-axis motor 45 are fixedly connected to the screws 44 at the corresponding positions.

[0037] In this embodiment, the two clamping plates 41 can clamp and position the steel coil by driving the dual-axis motor 45, making the steel coil more stable when flipping and preventing it from slipping off the flipping table 2 or collapsing due to inertia during the flipping process.
