Description

Technical Field

[0001] The utility model relates to the technical field of a plate rolling anti-dropping device, in particular to a plate rolling anti-dropping device for a port clamp. Background Art

[0002] The device to prevent the roll from falling off for port clamps is a key safety device designed to prevent the roll from accidentally falling off during port loading and unloading operations. Its main functions include safely fixing the roll, ensuring that the roll is firmly clamped in the clamp by clamping, fixing or other mechanical means, effectively avoiding accidents that may occur during transportation or loading and unloading. In addition, the device can protect the surface of the roll, prevent damage or deformation, and maintain the integrity and appearance of the roll through appropriate clamping force and mechanical design. In terms of operational efficiency, its design enables operators to carry out loading and unloading operations more safely and efficiently, reducing accidental risks, and complying with safety standards and regulations for ports and industrial environments.

[0003] The traditional port clamp roll plate anti-drop device is mainly composed of the clamp body, fixing mechanism, anti-drop device, adjustment mechanism, safety sensor and control system, as well as durable materials and anti-corrosion treatment. The clamp body includes an adjustable clamp to adjust the clamping force according to the roll plate diameter and thickness; the fixing mechanism is used to firmly install the clamp on the lifting equipment or other appropriate position to prevent movement or shaking; the anti-drop device increases friction and stability through the design of clamping mechanism, safety locking device and anti-slip rubber pad to ensure the safe fixation of the roll plate; the adjustment mechanism adjusts the clamping force and position to adapt to different roll plate characteristics; the safety sensor and control system monitor the roll plate position and clamping state to ensure that the operation meets safety standards.

[0004] If the port clamp in the prior art lacks a device to prevent accidental opening, it may cause serious safety and economic problems. During operation, if the clamp opens accidentally, the rolled plate or other cargo will fall from a height, causing serious material loss and financial loss. In addition, the fallen cargo will cause damage to surrounding facilities, equipment or other cargo, further increasing the cost of repair and replacement. More importantly, the opened clamp will threaten the safety of the operator and cause injury or accidents. Therefore, a device for preventing the rolled plate from falling for the port clamp is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a device for preventing a plate from falling when rolling up a port clamp, comprising a clamping jaw 1 and a hollow plate 3, a support plate 13 is fixedly connected to the top of the clamping jaw 1, a fixing ring 12 is fixedly connected to the top of the support plate 13, a first spring 11 is arranged on the outer wall of the fixing ring 12, a base 14 is fixedly connected to one end of the first spring 11, a first fixing column 10 is fixedly connected to the top of the base 14, a pressure block 5 is fixedly connected to the top of the first fixing column 10, an outer wall of the first fixing column 10 is slidably connected to the inner wall of the first spring 11, a gasket 21 is fixedly connected to the inside of the clamping jaw 1, and a magnetic sensor 22 is fixedly connected to the inside of the clamping jaw 1.

[0033] Specifically, when the steel coil is suspended, the internal pressure block 5 moves downward under the action of the force. This movement causes the first fixed column 10 at the bottom to start moving, and the movement of the first fixed column 10 drives the first spring 11 on the outer wall to contract. At the same time, the first spring 11 moves inside the fixed collar 12. Subsequently, through the force of the first fixed column 10, the base 14 at the bottom begins to move and rests against the inside of the clamp 1. At the same time, the base 14 also contacts the top of the gasket 21 inside the clamp 1. This base 14 has a certain magnetism, and its magnetic field enables the magnetic sensor 22 to sense and transmit signals. At the same time, after receiving the signal, the magnetic sensor 22 locks the gear 8 at the output end of the motor 7, effectively preventing the coil from accidentally falling and ensuring safe operation.

[0034] Reference Figure 1 and Figure 4 A hollow plate 15 is fixedly connected to the top of the hollow plate 3, a rotating plate 16 is rotatably connected to the inner wall of the hollow plate 15, a second fixed column 17 is fixedly connected to the top of the rotating plate 16, a hook 2 is fixedly connected to the top of the second fixed column 17, a third fixed column 19 is fixedly connected to the side wall of the hook 2, a second spring 20 is provided on the outer wall of the third fixed column 19, a clamping plate 18 is rotatably connected to the side wall of the hook 2, and one end of the second spring 20 is fixedly connected to the side wall of the clamping plate 18.

[0035] Specifically, when using the port clamp, in order to prevent the rolled plate from accidentally falling, the overhead hook must first be slid so that one side of it is on the side of the clamping plate 18, and at the same time the overhead hook slides into the inside of the hook 2. Subsequently, the clamping plate 18 is subjected to force to cause the second spring 20 to contract, and this action again causes the clamping plate 18 to cling to the inner wall of the hook 2. While the rolled plate is being hung, the force of the hook 2 causes the second fixed column 17 to start rotating, and the movement of the second fixed column 17 drives the rotating disk 16 to rotate, and at the same time the rotating disk 16 completes the rotation inside the hollow disk 15, thereby achieving the effect of locking the overhead hook.

[0036] Reference Figure 1 and Figure 2 A transmission assembly is provided on the side wall of the clamping jaw 1, and the transmission assembly is used to drive the clamping jaw 1 to move. The transmission assembly includes a fixed plate 6, and the side wall of the fixed plate 6 is fixedly connected to the side wall of the clamping jaw 1. The side wall of the fixed plate 6 is fixedly connected to a rack 9, and the side wall of the hollow plate 3 is fixedly connected to a hollow block 4. The inside of the hollow block 4 is fixedly connected to a motor 7, and the output end of the motor 7 is fixedly connected to a gear 8, and the gear 8 is meshed with the rack 9.

[0037] Specifically, the output end of the motor 7 drives the gear 8 to start rotating, and the power of the gear 8 acts on the rack 9 on the outer wall, pushing the rack 9 to move inside the hollow plate 3. As the rack 9 moves, the fixed plate 6 on the side wall starts to move, and the movement of the fixed plate 6 simultaneously drives the clamping jaw 1 to move, so that the clamping jaw 1 effectively clamps and fixes the steel coil, ensuring its safety and stability during handling and transportation.

[0038] Working principle: When using the port clamp to prevent the plate from falling, first slide one side of the ceiling hook on the side of the card plate 18, and at the same time, the ceiling hook slides into the inside of the hook 2, and then the force of the card plate 18 causes the second spring 20 to contract, and the contraction of the second spring 20 will make the card plate 18 fit the inner wall of the hook 2 again, and at the same time, when the plate is hung up, the force of the hook 2 causes the inside of the second fixed column 17 to rotate, and the force of the second fixed column 17 drives the rotating disk 16 to rotate, and at the same time, the rotating disk 16 rotates inside the hollow disk 15, achieving the effect of locking the ceiling hook, and at the same time, the output end of the motor 7 drives the gear 8 to rotate, and the force of the gear 8 drives the rack 9 of the outer wall to move, and the movement of the rack 9 is inside the hollow plate 3, and at the same time, the movement of the rack 9 drives the fixed plate 6 of the side wall to move, and at the same time, the movement of the fixed plate 6 drives the clamping claw 1 to move, thereby achieving the clamping effect. The effect of the steel coil is that when the steel coil is hung up, the internal pressure block 5 is forced to move downward, and the force of the pressure block 5 drives the first fixed column 10 at the bottom to move, and the movement of the first fixed column 10 drives the first spring 11 of the outer wall to contract. At the same time, the movement of the first spring 11 is inside the fixed ring 12, and then the force of the first fixed column 10 causes the base 14 at the bottom to move, and the base 14 is against the inside of the clamp 1, and at the same time, the base 14 is against the top of the gasket 21 inside the clamp 1, and the base 14 has a magnetic field, which senses the magnetic sensor 22 to transmit a signal. At the same time, the signal transmitted by the magnetic sensor 22 locks the gear 8 at the output end of the motor 7. After the gear 8 is locked, the clamp 1 is prohibited from opening. In summary, there is a certain distance between the gasket 21 and the base 14 to prevent the inner wall of the steel coil from directly contacting the magnetic sensor 22, thereby achieving the effect of preventing the clamp from accidentally opening.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
