Description

Technical Field

[0001] The utility model relates to the technical field of steel coil packing, and specifically, to an anti-tipping device before steel coil packing. Background Technique

[0002] A steel coil is formed by winding cold-pressed sheet steel into a coil shape for convenient storage and transportation.

[0003] The utility model with the authorization announcement number of CN220054296U provides an anti-tipping device before steel coil packing. By setting a motor to drive a transmission gear to rotate, and then driving a transmission rack to drive a telescopic adjusting rod to move, the steel coil limiting connecting plate can firmly fit against the side wall of the steel coil, having a good limiting effect.

[0004] When the above-mentioned anti-tipping device before steel coil packing loads steel coils with different widths, the center of gravity of the device will change, while the position of the lifting frame arranged on the top of the square connecting frame remains unchanged. When connecting the hook of the hoisting equipment to the lifting frame and hoisting the device loaded with the steel coil, the device is prone to tilt because the center of gravity is not directly below the hook. When one end of the steel coil close to the limiting connecting plate topples to the lower position, a large pressure will be exerted on the limiting connecting plate, causing the limiting connecting plate to bend or even break, resulting in potential safety hazards. In view of this, we propose an anti-tipping device before steel coil packing. Summary of the Invention

[0005] The purpose of the utility model is to provide an anti-tipping device before steel coil packing to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, one of the purposes of the utility model is to provide an anti-tipping device before steel coil packing, including a support frame. The support frame is of a C-shaped structure. A lower slideway is opened inside the horizontal section at the lower side of the support frame. A square rod is slidably arranged inside the lower slideway. One end of the square rod penetrates through the side wall of the lower slideway and is fixedly connected with a vertical plate. A lifting lug is arranged on the top of the horizontal section at the upper side of the support frame. A displacement mechanism is arranged on the support frame. The displacement mechanism is used to drive the square rod to move horizontally to adjust the distance between the vertical plate and the support frame. While adjusting the distance between the vertical plate and the support frame, the displacement mechanism horizontally adjusts the position of the lifting lug. A strengthening mechanism is arranged on the side of the vertical plate away from the support frame.

[0007] As a further improvement of the technical solution, the displacement mechanism includes a lower lead screw rotatably connected inside the lower slideway. A cavity is formed on the side of the square rod away from the vertical plate. The lower lead screw is threadedly connected to the inner wall of the cavity. An upper slideway is formed at the top of the horizontal section on the upper side of the support frame. The side profile of the upper slideway is an inverted T-shaped structure. A slider is slidably arranged on the inner wall of the upper slideway. The lifting lug is fixedly connected to the upper surface of the slider. The upper end of the lifting lug passes through the upper slideway and extends upward. An upper lead screw is rotatably connected inside the upper slideway. The slider is threadedly connected to the outer wall of the upper lead screw.

[0008] As a further improvement of the technical solution, the ends of the lower lead screw and the upper lead screw away from the vertical plate respectively penetrate through one side of the lower slideway and the upper slideway and extend out. A transmission rod is rotatably connected to the side of the support frame away from the vertical plate. Upper bevel gears are fixedly connected to the upper end of the transmission rod and the end of the upper lead screw away from the vertical plate. The two upper bevel gears are meshed with each other. Lower bevel gears are fixedly connected to the lower end of the transmission rod and the end of the lower lead screw away from the vertical plate. The two lower bevel gears are meshed with each other.

[0009] As a further improvement of the technical solution, a motor is fixedly installed on the side of the support frame away from the vertical plate. The output shaft of the motor is drivingly connected with a driving gear. A driven gear is fixedly connected to the outer wall of the transmission rod. The driven gear is meshed with the driving gear.

[0010] As a further improvement of the technical solution, the strengthening mechanism includes an end plate arranged inside the cavity. The end plate is in close contact with the end of the lower lead screw close to the vertical plate. An extension rod is fixedly connected to the side of the end plate away from the lower lead screw. The other end of the extension rod successively penetrates through the cavity and the side wall of the vertical plate and is hinged with a T-shaped frame. Sleeve frames are slidably sleeved at both ends of the horizontal section of the T-shaped frame. The sleeve frames are fixedly connected to the side of the vertical plate away from the square rod. A spring is sleeved outside the extension rod. The two ends of the spring are respectively fixedly connected to the inner wall of the cavity and the end plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For the anti-tipping device before steel coil packing, when adjusting the distance between the vertical plate and the support frame so that the vertical plate cooperates with the vertical section of the support frame to prevent the horizontal movement of the steel coil, the position of the lifting lug is horizontally adjusted so that the lifting lug moves directly above the center of gravity of the device after loading the steel coil. When using a lifting device to lift the steel coil, it can prevent the support frame loaded with the steel coil from tilting in the air, improving the safety during the lifting of the steel coil.

[0013] 2. Before the steel coil is packaged, when the square rod drives the vertical plate to move to the position where it contacts the steel coil, the distance between the connection point of the extension rod and the T-shaped frame and the square rod increases, flipping the T-shaped frame from the vertical state to the inclined state. The inclined T-shaped frame, extension rod, and vertical plate form a triangular structure, enhancing the structural strength of the vertical plate and reducing the possibility of the vertical plate bending or even breaking.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Embodiment

[0025] Please refer to Figure 1 - Figure 2 As shown, one of the purposes of this embodiment is to provide an anti-tipping device before steel coil packing, which includes a support frame 1. The support frame 1 is of a C-shaped structure. A sliding channel 11 is opened inside the horizontal section at the lower side of the support frame 1. A square rod 2 is slidably arranged inside the sliding channel 11. The sliding channel 11 restricts the horizontal movement of the square rod 2. One end of the square rod 2 penetrates through the side wall of the sliding channel 11 and is fixedly connected to a vertical plate 3. A lifting lug 4 is arranged at the top of the horizontal section at the upper side of the support frame 1. When using a lifting device to lift a steel coil, connect the hook of the lifting device to the lifting lug 4. A displacement mechanism 5 is arranged on the support frame 1. After inserting the horizontal section at the lower side of the support frame 1 into the hollow channel of the steel coil and making the steel coil contact the vertical section of the support frame 1, lift the support frame 1 upward by a certain height so that the vertical plate 3 and the vertical section of the support frame 1 are respectively located on both sides of the upper half of the steel coil. Then drive the square rod 2 to move horizontally through the displacement mechanism 5 to adjust the distance between the vertical plate 3 and the support frame 1 until the vertical plate 3 is in close contact with the side of the steel coil away from the vertical section of the support frame 1. At this time, the vertical plate 3 cooperates with the support frame 1 to prevent the steel coil from moving horizontally and prevent the steel coil from rolling. While the displacement mechanism 5 adjusts the distance between the vertical plate 3 and the support frame 1, it horizontally adjusts the position of the lifting lug 4. After the device loads steel coils of different widths, the position of its center of gravity will change. The center of gravity position is directly above the middle section of the steel coil. The stroke of the lifting lug 4 is positively correlated with the stroke of the vertical plate 3. When the vertical plate 3 moves to limit steel coils of different widths, the moving lifting lug 4 can move directly above the center of gravity of the device after loading the steel coil. When using a lifting device to lift the steel coil, it prevents the support frame 1 loaded with the steel coil from tilting in the air and improves the safety during the lifting of the steel coil.

[0026] To horizontally adjust the position of the lifting lug 4 while adjusting the distance between the vertical plate 3 and the support frame 1, the structure of the displacement mechanism 5 is refined as follows. Refer to Figure 2 and Figure 5, the displacement mechanism 5 includes a lower lead screw 51 rotatably connected inside the lower slideway 11. A cavity 21 is formed on the side of the square rod 2 away from the vertical plate 3. The lower lead screw 51 is threadedly connected to the inner wall of the cavity 21. When the lower lead screw 51 rotates, due to the threaded connection between the lower lead screw 51 and the inner wall of the cavity 21, the square rod 2 moves horizontally along the inner wall of the lower slideway 11, and the square rod 2 drives the vertical plate 3 to move synchronously. The upper slideway 52 is formed at the top of the horizontal section of the support frame 1 on the upper side. The side profile of the upper slideway 52 is an inverted T-shaped structure. A slider 54 is slidably arranged on the inner wall of the upper slideway 52. The upper slideway 52 restricts the horizontal movement of the slider 54. The lifting lug 4 is fixedly connected to the upper surface of the slider 54. The upper end of the lifting lug 4 passes through the upper slideway 52 and extends upward. An upper lead screw 53 is rotatably connected inside the upper slideway 52. The slider 54 is threadedly connected to the outer wall of the upper lead screw 53. When the upper lead screw 53 rotates, due to the threaded connection between the upper lead screw 53 and the slider 54, the slider 54 is driven to move horizontally along the inner wall of the upper slideway 52, and the lifting lug 4 moves horizontally synchronously with the slider 54. By rotating the lower lead screw 51 and the upper lead screw 53 synchronously, it is possible to horizontally adjust the position of the lifting lug 4 while adjusting the distance between the vertical plate 3 and the support frame 1. When the vertical plate 3 moves towards the support frame 1, the lifting lug 4 moves towards the vertical section of the support frame 1. When the vertical plate 3 moves away from the support frame 1, the lifting lug moves away from the vertical section of the support frame 1.

[0027] To rotate the lower lead screw 51 and the upper lead screw 53 synchronously, the ends of the lower lead screw 51 and the upper lead screw 53 away from the vertical plate 3 respectively penetrate through one side of the lower slideway 11 and the upper slideway 52 and extend out. A transmission rod 56 is rotatably connected to the side of the support frame 1 away from the vertical plate 3. Upper bevel gears 561 are fixedly connected to the upper end of the transmission rod 56 and the end of the upper lead screw 53 away from the vertical plate 3. The two upper bevel gears 561 are meshed with each other. Lower bevel gears 562 are fixedly connected to the lower end of the transmission rod 56 and the end of the lower lead screw 51 away from the vertical plate 3. The two lower bevel gears 562 are meshed with each other. A motor 58 is fixedly installed on the side of the support frame 1 away from the vertical plate 3. The output shaft of the motor 58 is drivingly connected to a driving gear 59. A driven gear 57 is fixedly connected to the outer wall of the transmission rod 56. The driven gear 57 is meshed with the driving gear 59. When the motor 58 is started, its output shaft drives the driving gear 59 to rotate. Through the meshing transmission between the driving gear 59 and the driven gear 57, the driven gear 57 drives the transmission rod 56 to rotate. The transmission rod 56 drives the upper bevel gears 561 and the lower bevel gears 562 at both ends to rotate synchronously. The other upper bevel gear 561 drives the upper lead screw 53 to rotate, and the other lower bevel gear 562 drives the lower lead screw 51 to rotate, thereby making the upper lead screw 53 and the lower lead screw 51 rotate synchronously. The motor 58 is externally connected to an electric control device, and its output shaft can switch the rotation direction. When the output shaft of the motor 58 rotates forward, the lifting lug 4 and the vertical plate 3 move towards the vertical section of the support frame 1. When the output shaft of the motor 58 rotates reversely, the lifting lug 4 and the vertical plate 3 move away from the vertical section of the support frame 1.

[0028] When the lifting equipment lifts the steel coil through the device, the vertical plate 3 blocks the steel coil from sliding along the outer wall of the lower horizontal section of the support frame 1. Due to the large weight of the steel coil, when the steel coil applies pressure to the vertical plate 3, the connection between the vertical plate 3 and the square rod 2 will be subjected to a large shear force. To share the shear force at the connection between the vertical plate 3 and the square rod 2 and extend the service life of the vertical plate 3, a strengthening mechanism 6 is provided on the side of the vertical plate 3 away from the support frame 1. When the vertical plate 3 moves horizontally towards the support frame 1 to prevent the steel coil from moving horizontally, the strengthening mechanism 6 enhances the structural strength of the vertical plate 3 and reduces the possibility of the vertical plate 3 bending or even breaking.

[0029] To enhance the structural strength of the vertical plate 3, the structure of the strengthening mechanism 6 is refined as follows. Referring to Figure 3 、 Figure 4 and Figure 6 , the strengthening mechanism 6 includes an end plate 61 arranged inside the cavity 21. The end plate 61 is in close contact with one end of the lower lead screw 51 close to the vertical plate 3. A extension rod 62 is fixedly connected to the side of the end plate 61 away from the lower lead screw 51. The other end of the extension rod 62 sequentially penetrates the cavity 21 and the side wall of the vertical plate 3 and is rotatably connected to a T-shaped frame 64. Sleeve frames 65 are slidably sleeved at both ends of the horizontal section of the T-shaped frame 64. The sleeve frames 65 are fixedly connected to the side of the vertical plate 3 away from the square rod 2. A spring 63 is sleeved outside the extension rod 62. Both ends of the spring 63 are fixedly connected to the inner wall of the cavity 21 and the end plate 61 respectively. When the square rod 2 drives the vertical plate 3 to move horizontally towards the support frame 1, the lower lead screw 51 prevents the end plate 61 and the extension rod 62 from moving horizontally, causing the spring 63 to elastically contract. The length of the extension rod 62 outside the square rod 2 increases, and the distance between the connection between the extension rod 62 and the T-shaped frame 64 and the square rod 2 increases. The horizontal section of the T-shaped frame 64 moves downward along the inner walls of the two sleeve frames 65, causing the extension rod 62 to drive the T-shaped frame 64 to rotate downward. The T-shaped frame 64 flips from the vertical state to the inclined state. The inclined T-shaped frame 64, the extension rod 62 and the vertical plate 3 form a triangular structure, enhancing the structural strength of the vertical plate 3. After the loading work of the device on the steel coil is completed, the square rod 2 is made to drive the vertical plate 3 to move horizontally away from the support frame 1. The spring 63 rebounds to push the end plate 61, so that the end plate 61 is always in close contact with the lower lead screw 51 until the T-shaped frame 64 returns to the vertical state again. The vertical T-shaped frame 64 can reduce the occupied space of the device, facilitate the transportation and storage of the device, and at the same time reduce the possibility of the T-shaped frame 64 and the extension rod 62 being damaged by being hit by hard objects.
